4. HOSPITAL A  hospital  is a  health care  institution providing  patient  treatment with specialized medical and nursing staff and medical equipment. best-known type of hospital is the general hospital, which typically has an  emergency department  to treat urgent health problems ranging from fire and accident victims to a sudden illness. A district hospital typically is the major health care facility in its region, with many beds for  intensive care  and additional beds for patients who need long-term care. Specialized hospitals include  trauma centers ,  rehabilitation hospitals ,  children's hospitals , seniors' ( geriatric ) hospitals, and hospitals for dealing with specific medical needs such as  psychiatric  treatment (see  psychiatric hospital ) and certain disease categories. Specialized hospitals can help reduce  health care costs  compared to general hospitals. Hospitals are classified as general, specialty, or government depending on the sources of income received. A  teaching hospital  combines assistance to people with teaching to medical students and nurses. A medical facility smaller than a hospital is generally called a  clinic . Hospitals have a range of departments (e.g.  surgery  and  urgent care ) and specialist units such as  cardiology . Some hospitals have  outpatient departments  and some have chronic treatment units. Common support units include a  pharmacy ,  pathology , and  radiology . Dept of Biomedical Engineering,VCET 4

5. HOSPITAL Hospitals are typically funded by  public funding , health organisations ( for profit  or  nonprofit ),  health insurance  companies, or  charities , including direct charitable donations. Historically, hospitals were often founded and funded by  religious orders , or by charitable individuals and leaders. Currently, hospitals are largely staffed by professional  physicians ,  surgeons ,  nurses , and  allied health practitioners , whereas in the past, this work was usually performed by the members of founding religious orders or by  volunteers .

9. Role of Hospitals in Health Care Dept of Biomedical Engineering,VCET 9 Medical care is a programme of services that should make available to the individual, and thereby to the community,all facilities of medical and allied services necessary to promote and maintain health of mind and body. This programme should take into account the physical, social and family environment, with a view to the prevention of disease, the restoration of health and the alleviation of disability. A Hospital is an integral part of a Social and Medical organisation , the function of which is to provide for the population complete health care, both curative and preventive, and whose outpatient services reach out to the family and its home environment; the hospital is also a centre for the training of health workers and biosocial research. —WHO definition of Hospital

10. Role of Hospitals in Health Care Dept of Biomedical Engineering,VCET 10 Individual as well as group health has evolved as a product of human biology, environment, ways of living, economic status, and health services. The physical and mental traits of a person are also determined among others, by his or her genetic endowment, as evidenced by the discovery of many disorders being of genetic origin. The health status and disease status are, thus, a result of the process of a continuous adjustment between the internal and external environment. The society’s health is influenced by the accessibility, affordability, quality, availability and utilisation of health services. The best health services are those that are easily accessible , both time-wise and distance-wise to all classes of society, those that can be afforded by the society and government which provides them and affordable by people who utilise them, of a minimum acceptable standard in keeping with the need of the users at each level, available to all classes of society who need them, and which range in their coverage from womb-to-tomb , with effective deployment of available resources.

11. Role of Hospitals in Health Care Dept of Biomedical Engineering,VCET 11 Environmental Health Services Environmental health services are considered as a component of public health, with overlaps. It covers the following: 1. Water supply 2. Pollution control 3. Sewage disposal 4. Food hygiene 5. Ecology and environmental pollution.

12. Role of Hospitals in Health Care Dept of Biomedical Engineering,VCET 12 Public Health Services Public health services are concerned with the following. 1. Control of communicable diseases 2. Sanitation 3. Maternal and child health 4. Public health education 5. Vital statistics 6. Health planning 7. Occupational health and reduction of health hazards.

13. Role of Hospitals in Health Care Dept of Biomedical Engineering,VCET 13 Personal Health Services Personal health services are the services provided by hospitals, health centres and nursing homes, apart from privately practising physicians. The care provided has been traditionally classified into: i . promotion of health, ii. prevention of disease, iii. early diagnosis and treatment, and iv. rehabilitation.

14. Role of Hospitals in Health Care Dept of Biomedical Engineering,VCET 14 Promotion of Health Promotion of health is not directed at any particular disease and is generally considered the responsibility of the individual. Good health practices promote health through adequate nutrition, exercise, rest, personal hygiene, health screening and health education. Although the primary responsibility is that of the individual, others outside the health system are also concerned with health promotion. Health promotion programmes aim at physical and mental fitness, diet, alcohol and drug abuse, recreation and genetic counselling. However, by itself, improved health is an insufficient incentive for many individuals to adapt good personal health practices. As a society we are concerned about placing incentives on members of the health team, but do little to place incentives on the individual. To cut down costs on hospital-based care, plans are now being proposed in many countries to provide financial incentives and disincentives through health insurance plans to individuals to promote their own health and avoid using health care services. Healthful behaviour tends to promote more healthful behaviour .

15. Role of Hospitals in Health Care Dept of Biomedical Engineering,VCET 15 Prevention of Disease Primary prevention is a service designed to protect against specific diseases through immunisation , use of specific nutrients and protection against occupational hazards and accidents. All diagnostic and therapeutic activity has a preventive component in that it seeks to prevent further deterioration of a man’s health. In this context, early detection of disease through mass screening services among vulnerable population helps in prevention of disease, although this approach is questioned by many from economic point of view. The cost of mass multiphasic screening can be high.

16. Role of Hospitals in Health Care Dept of Biomedical Engineering,VCET 16 Early Diagnosis and Treatment The earlier a disease is diagnosed and treated, the better it is from the point of view of prognosis and for preventing secondary cases in the community. The principle of early detection and treatment of cases in the general population is the basis on which disease control is built. A good deal of early diagnosis now comes through hospital-based screening for disease programmes and periodical medical checkups among the apparently healthy people.

17. Role of Hospitals in Health Care Dept of Biomedical Engineering,VCET 17 Primary, Secondary and Tertiary care : Treatment services are categorised as primary, secondary and tertiary care. Primary care is the entry point into the health system and usually obtained through family physicians and through the hospital-based ambulatory outpatients services—besides the community health workers and multipurpose workers at the grass-roots level. WHO defined primary health care as “essential health care based on practical, scientifically sound and socially acceptable methods and technology made universally accessible to individuals and families. It is the first level of contact of individuals, the family and the community....and constitutes the first element of a continuing health process.”2 Secondary care services are at an intermediate level in the chain of hospitals. The services of smaller peripheral hospitals and general hospitals would fit in this category. Tertiary care refers to highly specialized care in specialist hospitals and speciality services provided in superspeciality centres and research centres .

18. Role of Hospitals in Health Care Dept of Biomedical Engineering,VCET 18 THE CHANGING ROLE OF HOSPITALS From its gradual evolution through the 18th and 19 th centuries, the hospital both in the eastern and the western world—has come of age only recently during the past 50 years or so, the concept of todays hospital contrasting fundamentally from the old idea of a hospital as no more than a place for the treatment of the sick. With the wide coverage of every aspect of human welfare as part of health care—viz. physical, mental and social wellbeing, a reachout to the community, training of health workers, biosocial research, etc.—the health care services have undergone a steady metamorphosis, and the role of hospital has changed, with the emphasis shifting from: i . acute to chronic illness ii. curative to preventive medicine iii. restorative to comprehensive medicine iv. inpatient care to outpatient and home care v. individual orientation to community orientation vi. isolated function to area-wise or regional function vii. tertiary and secondary to primary health care viii. episodic care to total care.

19. Role of Hospitals in Health Care Dept of Biomedical Engineering,VCET 19 HOSPITAL VIEWED AS A SYSTEM A hospital can be variously described as a factory, an office building, a hotel, an eating establishment, a medical care agency, a social service institution and a business organisation . In fact, it is all of these in one, and more. Sometimes it is run by business means but not necessarily for business ends. This complex character of the hospital has fascinated social scientists as well as lay people. Management science defines a system as “a collection of component subsystem which, operating together, perform a set of operations in accomplishment of defined objectives.” A system is viewed as anything formed of parts placed together or adjusted into a cohesive whole. Every system is therefore a part of a large system and has its own subsystem. A system is construed as having inputs which undergo certain processing and get transformed into output, the output itself in turn ending feeback to the input and the process, which can be altered to achieve still better output. A system is therefore a continuous and dynamic phenomenon Transformation of matter, energy or information produce the output by two processes, viz . decision process, i.e. the process of deciding what to do, how best to do it, when to do it and so on, and action process, i.e. the process of putting the above decisions in action. Fig. 1.1: Conceptual representation of a system

20. Role of Hospitals in Health Care Dept of Biomedical Engineering,VCET 20 Peculiarities of a Hospital System In spite of the simple definition of a system, a hospital system is more than the sum of its parts. The peculiarities of a hospital system are as follows. 1. A hospital is a open system which interacts with its environment. 2. Although a system generally has boundary, the boundaries separating the hospital system from other social systems are not clear but rather fuzzy. 3. A system must produce enough outputs through use of inputs. But the output of a hospital system is not clearly measurable. 4. A hospital system has to be in a dynamic equilibrium with the wider social system. 5. A hospital system is not an end in itself. It must function, as a part of the larger health care system. 6. A hospital system like other open social systems tends towards elaboration and differentiation, i.e. as it grows, the hospital system tends to become more specialised in its elements and elaborate in structure, manifesting in the creation of more and more specialised departments, acquisition of new technology, expansion of the “product lines” and scope of services.

21. Role of Hospitals in Health Care Dept of Biomedical Engineering,VCET 21 Hospital as a Social System Sociologists have considered hospital as a social system based on bureaucracy, hierarchy and superordination subordination. A hospital manifests characteristics of a bureaucratic organisation with dual lines of authority, viz. Administrative and Professional. In teaching hospitals and in some others, many professionals at the lower and middle level (interns, junior resident, senior residents, registrar) are transitory, whileas in others, all medical professionals are permanent with tenured positions and nontransferable jobs. In order to continue in a orderly fashion, every social system has to fulfil the functional needs of that system, viz. the need for pattern maintenance, the need for adaptation, for goal attainment and integration.

24. Role of Hospitals in Health Care Dept of Biomedical Engineering,VCET 24 INTRAMURAL AND EXTRAMURAL FUNCTIONS OF HOSPITAL The activities of the present day hospital can be divided into two distinct types—intramural and extramural. Intramural activities are confined within the walls of the hospital, whereas extramural activities are the services which radiate outside the hospital and to the home environment and community.

26. Role of Hospitals in Health Care Dept of Biomedical Engineering,VCET 26 HOSPITAL AND COMMUNITY The ultimate purpose of the health services is to meet effectively the total health needs of the community. There are a lot of factors which determine the health needs of community and solutions to them. Some of the important factors are listed in Table 1.7. A good hospital would build its services on the knowledge and understanding of the community it is to serve, its success will depend upon the involvement of many groups, both professional and nonprofessional within and outside the hospital.

28. Role of Hospitals in Health Care Dept of Biomedical Engineering,VCET 28 The Providers, Support Group and Community The hospital being a distinct, albeit integral, part of the health service, is influenced by all the above mentioned factors and the health services in turn influence those factors. It has to deal with three different groups which from the larger community. 1. The first group is the “providers” of medical care, viz. the doctors, nurses, technicians and paramedical personnel. 2. The second group is management, administrative and support group comprising of personnel dealing with nonclinical functions of the hospitals, such as diet, supplies, maintenance, accounts, housekeeping, watch and ward, etc. 3. The third group and the most important one for whose benefit the first two groups exist in the first place, is that of the patients who seek hospital service and their attendants, relatives and associates who, along with patient come in close contact of the hospital. This group is broadly termed as the “community.”

29. Role of Hospitals in Health Care Dept of Biomedical Engineering,VCET 29 PRIMARY HEALTH CARE (PHC) AND HOSPITALS Realisation of the importance of the role of hospitals in primary health care (PHC) was generated as a result of the International conference on Primary Health Care held at Alma Ata in the erstwhile USSR in 1978 jointly sponsored by WHO and UNICEF. PHC is a concept providing comprehensive health care, i.e. promotive, preventive, curative, and rehabilitative services covering the main health problems in the community. have an important role in fostering and encouraging the growth of primary health care. Health being dependent on economic conditions and correlated to social and cultural values of the society, the quality, quantity, nature and content of health services under this concept are bound to vary between different societies. The exercise of providing primary medical care (supported by other components of medical and health services) has evolved into certain concepts based on basic technical knowledge. “Health for all by 2000 AD” declared as a goal of all nations at Alma Ata and accepted by India needs to be supported by all components of medical and health care services.

30. Role of Hospitals in Health Care Dept of Biomedical Engineering,VCET 30 Elements of Primary Health Care Eight essential elements of PHC as described by the WHO are as follows.9 1. Adequate nutrition 2. Safe and adequate water supply 3. Safe waste disposal 4. Maternal and child health and family planning services 5. Prevention and control of locally endemic diseases 6. Diagnosis and treatment of common diseases and injuries 7. Provision of adequate drugs and supplies 8. Health education.

31. Role of Hospitals in Health Care Dept of Biomedical Engineering,VCET 31 Benefits to the Health Care System Tremendous costs are incurred everytime a patient is treated in a hospital who could well be treated in an efficient PHC facility which is inexpensive, avoiding the overuse of the hospital by unnecessary patient self-referral. However, there has been a traditional hospital disinterest in PHC activities. The interest of acute care hospitals has been centering around development of quality secondary and tertiary care facilities and programmes . Hospitals have viewed their role as delivery of curative services and not in early intervention, reduced mortality, prevention of disease or health education which are the basis of most PHL programmes . However, there is now a growing realization of the role hospitals can play in PHC.

32. Role of Hospitals in Health Care Dept of Biomedical Engineering,VCET 32 Referral Function 1. Organising a two way referral system from mobile and outreach clinics to the hospital and referral back with reports for follow-up 2. Backing up the referral system with medical records 3. Organising visits of hospital specialists to outreach clinics 4. Carry out training and reinforcing skills at PHC workers by visiting specialists 5. Giving preferences to patients referred from PHC centres for specialist clinics and for admissions.

33. Role of Hospitals in Health Care Dept of Biomedical Engineering,VCET 33 Support Function 1. Providing logistics support in respect of equipment, materials, drugs and other supplies 2. Reinforcing diagnostic capabilities of PHC workers and outreach clinics 3. Providing transport for referrals and outreach services 4. Making hospitals facilities available for training and retraining of PHC workers.

34. Planning the Hospitals Dept of Biomedical Engineering,VCET 34 HOSPITAL PLANNING TEAM One must realise in the very beginning that hospital project planning and execution is likely to be a difficult and frustrating task. All the people involved in the delivery as well as utilization of services are concerned with hospital planning. The people, patients, nursing, medical staff and the management all have their own peculiar requirements. Technical requirements of a particular professional group in isolation have led to creation of physical forms limited in their utility. On the other hand, the interest of administrators is attracted by other than technical requirements of patients, community and owners. A critical understanding of these relationships is necessary to blend the differences of professional prestige, functional requirements and administrative considerations. Suitably qualified and competent planning staff are scarce to find. And they will need a long time to do the necessary work in a careful manner at each stage. It is a common practice, once the idea of a hospital has taken root, to go ahead too hastily in the preparation of building plans without much deliberation.

36. Planning the Hospitals Dept of Biomedical Engineering,VCET 36 Hospital Architect The architect has to acquire an understanding of the comprehensive technical and administrative needs of the hospital. His responsibility is to translate clinical and administrative requirements into architectural and engineering realities which encompass site selection, orientation of buildings, supervision of construction, utilities and electrical and mechanical installations. The requirements have to be understood in depth by the architect from the hospital consultant, from which should develop a programme in writing stating clearly all the requirements in comprehensive terms, viz. number of beds, their distribution, departmental needs, area requirements, major equipment, number and type of personnel to be employed, departmental functions and relationships.

38. Planning the Hospitals Dept of Biomedical Engineering,VCET 38 ASSESSMENT OF THE EXTENT OF NEED FOR THE HOSPITAL SERVICES One of the first task of the planning team is collection of data to assess the extent of need for the particular hospital and the range of services required. Such data should usually be available with the existing health care agencies in the government sector with local, district or state health authorities. There are two methods of assessing the extent of functional need for a hospital. They are (1) the empirical method which applies the norms of the past and rules of thumb to the problem, with appropriate modifications to suit local conditions, and the (2) analytical method which makes a more fundamental, systematic approach to the problem. The emperical method hinders evolution of new solutions whileas the analytical method lacks the controlling elements of the “norms”. Use of such norms and rules of thumb also tend to perpetuate past faults. The analytical method overcomes some of these faults. In practice, therefore, a combination of the two method will usually be applied.

39. Planning the Hospitals Dept of Biomedical Engineering,VCET 39 Relationship between Demand and Need 1. Demand for hospital services can be estimated by studying statistical returns of current usage and morbidity statistics. 2. Measurement of need for hospital services takes account of a more positive approach by aiming at a quantitative estimation of the amount of illness in the community which would require hospital services.

40. Planning the Hospitals Dept of Biomedical Engineering,VCET 40 Levels of Medical Care Level of care is primarily determined by the level of staff in crucial role, i.e. the staff involved in decision making in diagnosis, treatment and referrals. There are four levels of medical care as in Table 2.3. Table 2.3: Levels of medical care Level of care Medical facility Level of decision maker 1. Primary Dispensary, Primary General practitioner health centre or medical assistant, multisubcentre purpose worker 2. Secondary District hospital Mostly general practi - (intermediate) or tioner , partly specialists equivalent 3. Tertiary Provincial or similar Specialists hospital (regional) 4. Quaternary Institute of research Superspecialists, and higher training researchers In practice, medical facilities of higher levels also provide care at lower levels. For example, a superspecialist institute will deliver tertiary care through specialists and secondary care through junior specialists and nonspecialists

41. Planning the Hospitals Dept of Biomedical Engineering,VCET 41 Factors Influencing Hospital Utilisation Hospital bed availability : As opposed to developed countries where utilisation is high because of large availability of hospital beds, in developing countries it is because of low bed : population ratio. A high available bed complement may lead to low bed occupancy rate. 2. Population coverage and bed distribution : Since full coverage of population depends upon equitable regional distribution rather than on total number of beds, an even distribution increases hospital utilisation by wider coverage of population. People from scarcely populated areas generally find it necessary to travel to district hospitals or metropolitan towns for more sophisticated type of medical care. 3. Age profile of population : A population with a high life expectancy (and consequently a higher proportion of aged persons) tends to raise the volume of hospitalisation . The effect of age on utilisation indices is reflected in an increase in the per person hospitalisation rate and in average length of stay. 4. Availability of medical services other than hospitals : Availability of well- organised dispensaries, outpatient clinics, mobile clinics and competent general practitioners reduce the load on hospital beds in an area. 5. Customs and attitudes of medical profession : Doctors order admissions primarily for medical reasons. On the other hand, people themselves influence the decision for admissions if a strong “hospital habit” is developed in them, or against admission because of fear of the hospital and unwillingness for separation from family. Physicians’ attitude on these matters and their philosophy on early ambulation and home care influence hospital bed utilisation.

42. Planning the Hospitals Dept of Biomedical Engineering,VCET 42 6. Method of payment for hospital services : Hospital services can be free, on payment by patient directly to the hospital, or by indirect payment through sickness insurance. Hospital utilisation is greatly influenced in the last case. 7. Availability of qualified medical manpower : In areas with very small number of qualified doctors, much illness remains undetected, and therefore admission rates are low. However, the customs and attitudes of medical profession and pattern of services available influence hospital utilisation more than the number of doctors. 8. Housing : Break up of the joint family system and a trend for nuclear families living in independent apartments result in increasing hospital admission because of inconveniences encountered in caring for the sick person at home. Shortage of home help in nuclear families and shortage of space in modern apartment dwellings are jointly responsible for demand for hospital admissions in urban areas. 9. Morbidity pattern : Acute communicable diseases result in a demand for short stay hospitals, whileas chronic infective and degenerative diseases create demand for long-stay institutions. The former raises the admission rate and bed turnover, the latter needs longer average length of stay. 10. Hospital bottlenecks : The efficiency with which supportive services (radiography and laboratory, etc.) support and reinforce the total hospital organisation has direct influence on hospital utilisation. Poor supportive services and cumbersome admission and discharge procedures act as “bottlenecks” and result in longer hospital stay. 11. Internal organisation : A high degree of specialization where specialist departments function as watertight compartments result in segmentation within a hospital, resulting in lesser degree of utilisation due to tight compartmentalisation of beds. This points out the need to provide the greatest flexibility in bed planning. 12. Public attitudes : There are certain factors which are of considerable importance in determining where people will go to receive medical care, these are public attitudes. The category includes social and religious attitudes, local customs and traditions, beliefs and mores, and group preferences.

43. Planning the Hospitals Dept of Biomedical Engineering,VCET 43 Geographical, Environmental and Miscellaneous Factors

44. Planning the Hospitals Dept of Biomedical Engineering,VCET 44 Bed Planning It is unlikely that elaborate calculations to determine number of beds will be required in starting a new hospital anywhere because nowhere has the bed:population ratio reached adequate levels. Even in cities where it has achieved such figures, more beds are required because of increasing urbanisation and high density of population. Here, it should be realised that the hospital facilities in an area are not only utilised primarily by the population in the vicinity of the hospital—the direct population, but also by people who will constitute the indirect population in the larger catchment area. When these population factors are worked out, the calculation for total bed requirements can proceed as per guidelines of WHO. Indices of direct and indirect admissions give the coverage hoped to be attained the assumed average length of stay and the occupancy rate indicate efficiency in the use of services. About 85 per cent bed occupancy is considered optimum.

45. Planning the Hospitals Dept of Biomedical Engineering,VCET 45

46. Planning the Hospitals Dept of Biomedical Engineering,VCET 46 CHOOSING A SITE General Considerations The second task of the planning team will be to choose the site for the hospital. Site is a very important factor for, upon the suitability of it, will depend the hospital’s fate and utility in future. With increasing demand on hospital beds, planning for expansion at a future date should always be kept in mind right at the outset while choosing the site. Therefore, the site should be large enough to enable future expansion and growth. However, strategic sites large enough for the project requirement may be hard to find in urban areas. In dense urban areas, a large site near the periphery of the present town is suitable that will, in due course become central to the major residential areas at a later date. Close collaboration with local town planning authorities will pay dividends in choosing the site.

47. Planning the Hospitals Dept of Biomedical Engineering,VCET 47 Land Requirements Determining the requirement of land depends upon many factors. In rural and semi-urban areas, plentiful land may be available permitting the hospital to grow horizontally. However, in urban areas there will always be great premium on land and the only available avenue will be a vertical growth. Site cover on a plot of land is expressed as percentage as under Site cover percentage= Total ground floor area of all buildings × 100 _________________________________________ Total area of site available

48. Planning the Hospitals Dept of Biomedical Engineering,VCET 48 Soil Structure In the selection of site, two very important factors that should be looked into the level of subsoil water and the structure of the soil. A preliminary soil survey to determine subsoil water level and the “bearing” quality of the soil will help determine the type of foundation, possibility of constructing a basement, and effectiveness of sewage plant (if it is to be built on the site). Public Utilities Three other important considerations in site selection are the availability of water supply, sewage disposal system and electric power. Water Water is required for patients and patient care activities in wards and also for the supportive services. The national building code of the ISI suggests 455 litres of water per consumer day (LPCD) for hospitals up to 100 beds and 340 LPCD for hospitals of 100 beds and over.5 For planning purposes, the overall requirement of water in hospitals is estimated at about 300 to 400 litres per bed per day. If staff quarters and nurses’ hostel are going to form part of the hospital complex, additional availability of water for these will have to be ensured. Storage capacity for three days requirement must be build at the site.

49. Planning the Hospitals Dept of Biomedical Engineering,VCET 49 Sewage Disposal Liquid and semisoild effluent in the hospital originate from all departments and service areas. Solid waste from hospitals is approximately 1 kg per bed per day. Liquid effluents will be about the same as the hospital’s requirement of water, i.e. between 300 to 400 litres per bed per day. Power Requirement of electric power is minimum 1 kW on a per bed per day basis. This includes the needs of all departments and services including power requirement of X-ray department, operation theatres, laboratories, central sterile supply department, laundry, and kitchen. A hospital with many life-support systems cannot afford to remain without power even for a short-time. It is preferable that power supply should be available on a multigrid instead of the unigrid system in general use, so that a continuous supply of electricity is assured to the hospital at all times. Besides this, stand-by generator is also a necessity.

50. Planning the Hospitals Dept of Biomedical Engineering,VCET 50 Electrical Substation A hospital will have its own transformer and electrical substation for distribution of power to various areas. The total substation area depending on the transformers capacity is given in Table

51. Planning the Hospitals Dept of Biomedical Engineering,VCET 51 CIRCULATION ROUTES The utility and success of hospital plans depend to a large extent on the circulation routes on hospital site and within buildings. Wayfinding in hospitals is a major problem for most new patients and many old ones too, leaving them with a feeling of helplessness and frustration. To ensure placement of departments and equipment in proper relationship, flow chats depicting movements of patients, personnel and visitors should be developed for predicted movements between departments and within D epartments. These charts should be provided to the architect and checked later against his preliminary drawing.

52. Planning the Hospitals Dept of Biomedical Engineering,VCET 52 Internal Circulation Internally, traffic routes are required for linking major clinical departments for use by patients and staff, and for delivery of supplies to these departments. The circulation space involves corridors, stairways and lifts. Corridors with less than 8 feet width are not desirable in hospitals, and protective corner beading is a necessity in hospital corridors. Ramps, steps, stairs : Handrails must be provided on both sides of steps and stairs, and should extend beyond the first and the last steps on at least one side. Hard, level, nonskid surfaces are essential for steps and stairs, and handrails must not be of slipery material.

53. Planning the Hospitals Dept of Biomedical Engineering,VCET 53 External Circulation Only one entrance to the hospital for vehicular traffic from the main road is desirable. Provided the entrance and exist points are wide enough to take two lanes of traffic, one entry has the advantage of clarity for all visiting traffic, and one exit the advantage of security from administrative viewpoint. The volume of external traffic reaching a hospital is quite enormous. Not only the patients but supplies, ambulances, staff and visitors need access to the hospital at different points. Supplies and stores also arrive on handcarts, pushcarts, rickshaws and other vehicles. Patients, their attendants and visitors come to hospitals in a variety of transport. Therefore, appropriate areas have to be earmarked for scooter, car, rickshaw and bicycle parking facilities for patients, visitors and staff.

54. Planning the Hospitals Dept of Biomedical Engineering,VCET 54 Distances Distances must be minimised for all movements of patients, medical, nursing and other staff and for supplies, aiming at minimum of time and motion. Similarly, the routes which the patients will have to take on stretchers, wheelchairs or on foot from their wards to the radiography department, laboratory and physiotherapy require careful thought to minimise the length of these routes. Compactness Functional efficiency and economy depend also on the compactness of the hospital. Horizontal development demands more land involving extra costs in development and installation of services, roads, water supply, sewage, electric lines and so on. From this angle, multistoreyed construction has the advantage of being convenient because of compactness.

55. Planning the Hospitals Dept of Biomedical Engineering,VCET 55 Parking For each inpatient bed there is likely to be at least one visitor a day. For each inpatient bed, there will be about 3 outpatients, many of them coming in cars, taxis, threewheelers and two-wheelers. One car parking space per two beds is desirable in metropolitan towns, lesser in smaller urban areas whileas much less in semiurban and rural areas. Additional parking for three-wheelers, scooters and motor cycles and separate parking for bicycles and rickshaws should be considered. Employees and staff parking areas are preferably separated from public parking. Landscaping The psychological effect of the visual impact of attractive grounds, buildings and surroundings on patients, visitors and staff cannot be underestimated. If possible the building is best located on a relatively high ground, the elevation being not so great to be a handicap for those approaching on foot.

56. Planning the Hospitals Dept of Biomedical Engineering,VCET 56 Visual Impact Architectural handling of the design determines the visual impact of the hospital. The architect has the opportunity to give visual expression to the human units of which the hospital is composed, or suppress these divisions in the interests of uniformity. ZONAL DISTRIBUTION AND INTER-RELATIONSHIPS OF DEPARTMENTS Each major department, clinical area, supportive units and administrative units have to be distributed over the site in appropriate zones to group them in such a manner that they are related to each other in contiguity and proximity. The departments which come in close contact with the public should be isolated from the main inpatient areas and allotted areas closer to the main entrance to the site. Such departments are the outpatient department and accident and emergency or casualty department. The supportive service departments, viz. the X-ray and laboratory services are extensively used by outpatients and need to be located as near the outpatient department as possible, at the same time integrated with the main inpatient wards. Therefore, these departments need to be located in such a way that they are approachable by separate entrances by outpatients as well as through inpatient areas, but preferably closer to the outpatient department.

57. Planning the Hospitals Dept of Biomedical Engineering,VCET 57 Hospital Stores If the volume of stores is only a few days’ consumption requirement and remains small, the various items of stores— rations and vegetables, linen, drugs and dressings and laboratory supplies can be kept in the respective storage areas in the kitchen, laundry, pharmacy and laboratory respectively. When the bulk of these goods is high, it is necessary to design a central place as hospital store. This will depend upon the hospital’s philosophy on materials management. The central store should be approachable by supply vehicles and should therefore have separate service entrance. The risk of fire and explosion in a medical supplies storehouse, storage of acids, inflammable materials and oxygen and other gas cylinders will require special attention while earmarking for such stores. CSSD Central sterile supply department (CSSD) mostly serves the operation theatres, but its other users include the emergency and casualty department, the wards and maternity suite and should be so sited as to be central to all these.

58. Planning the Hospitals Dept of Biomedical Engineering,VCET 58 Hospital Kitchen It will have to be located taking into consideration the prevailing wind direction so that smoke and kitchen odours are not constantly wafted to patient care areas. The best site for a kitchen is at the ground level. However, kitchens on first, second and higher floors are in existence, with stores located on ground floor and connected to the kitchen with lift. Hospital Workshop A large quantum of various types of mechanical and electrical equipment is installed in a hospital and requires repair and preventive maintenance. Even if the major installation, plant and equipment may have maintenance and repair contracts with outside agencies for maintenance, some equipment will from time to time require repairs by the hospital’s inhouse maintenance staff. No large hospital can function satisfactorily without a workshop.

59. Planning the Hospitals Dept of Biomedical Engineering,VCET 59 Laundry Mechanical laundries are becoming popular with larger hospitals. Used linen from wards, operation theatres and delivery suites may be infected, and therefore needs careful handling at an area remote from all other clinical and supportive services departments. If the indigenous dhobi ghat type of laundry arrangement are planned, then space for bhatties , dhobi-stores , drying sheds and ironing rooms have to be catered for at an appropriate area, preferably at a remote corner of the site with plentiful supply of water.

60. Planning the Hospitals Dept of Biomedical Engineering,VCET 60 Miscellaneous There are some more points that remain to be considered for zonal distribution at this stage. They are as follows: 1. Medical Gases A reliable supply of medical gases and vacuum is a prerequisite for a modern hospital. Medical gases for patient care activities in hospital include medical oxygen, nitrous oxide, carbon dioxide, medical grade air and vacuum for suction. All these (except suction) are provided in metal storage cylinders. Medical air : Compressed air is required to operate surgical instruments such as pneumatic drills and saws in operating rooms and procedure rooms. Air is also used to run ventilations in ICU and other units. Carbon dioxide : It is injected during laparoscopy, endoscopy, arthroscopy, etc. to enlarge and stabilise body cavities for better visibility of the surgical field in laparoscopic surgery.

61. Planning the Hospitals Dept of Biomedical Engineering,VCET 61 Colour coding of gas pipelines distribution system Item Colour of pipeline • Oxygen – Yellow • Nitrous oxide – Dark blue • Compressed air – Sky blue • Vacuum – Sky blue 2. Size and location of water storage tanks—whether undergound , overhead or roof mounted. Storage capacity should be at least three times the total daily requirement. 3. Location of the hospital incinerator where trash and infected material will be burned. 4. Boiler house for supply of steam to laundry, CSSD and kitchen. 5. Garages for ambulances and staff vehicles. 6. Mortuary for storage of dead bodies, and postmortem room. 7. Residential campus for specialists, residents, nurses and other essential staff. 8. A “community centre ” with grocery and fruit shop, barber’s shop, newspaper and bookstall, chemist shop, and a community hall. 9. Dharamshala or choultry for attendants and relatives of the patients to stay.

62. Planning the Hospitals Dept of Biomedical Engineering,VCET 62 Bed distribution : It has been generally found that about 165 out of every thousand population will be hospitalised for an average of about seven days each. The number of beds necessary to care for this number will be about 3 to 4 per thousand population. Determining the bed size of the hospital in governed by the service capacity to be provided which itself will depend on the projected number of admissions and consultations. Admissions and consultations will reflect in the number of beds and consulting rooms that would be necessary. Making calculations for beds will require data on the morbidity pattern in the dependent population and the average length of stay. With this information available, beds per 1000 population required for a given population in a given region is calculated by the following formulae: Bed : population = A × S × 100 ________________________ 365 × PO where, A = number of inpatient admissions per thousand population per year S = average length of stay (ALS) PO = percentage occupancy.

63. Planning the Hospitals Dept of Biomedical Engineering,VCET 63 Operation Theatres As a high standard of asepsis is required to be maintained, it is advantageous to group the operating rooms together in one area, keeping in view the concept of protective, clean, aseptic and disposal zones. A good standards of air hygiene also requires recourse to artificial ventilation Airconditioning). This is achieved economically by pooling all the operating rooms together in one complex. Majority of operations—including ophthalmic, ENT and orthopaedic —can be carried out in well-designed standard operating rooms which also provide maximum flexibility in their use. However, in large hospitals, at least one or two operating rooms should be larger than the rest to facilitate wheeling in of bulky equipment for specialised surgery. The number of operating rooms will be dependant on the number of surgical beds. On an average an operation theatre can cater for a mix of 4 to 5 major and minor operations per working day.

64. Planning the Hospitals Dept of Biomedical Engineering,VCET 64 Laboratory Laboratory tests are ordered for diagnosis and assessment of response to treatment. A well-planned and equipped laboratory can reduce the running costs of a hospital by reducing length of stay of inpatients by rapid return of investigation results facilitating early diagnosis. By its link with the outpatient department, it can also reduce the number of patients admitted solely for laboratory investigations. Many a times a false sense of economy is sought to be achieved by curtailing the space requirements of the laboratory by shifting it in an insignificant corner of the hospital. Rapid developments in diagnostic laboratory methods are taking place resulting in increasing demand for space and equipment. To reduce potential health hazards due to the very nature of tasks performed in the laboratory and to obviate laboratory accidents, a hospital laboratory space needs to be provided on generous lines.

65. Planning the Hospitals Dept of Biomedical Engineering,VCET 65 CLIMATIC CONSIDERATION IN DESIGN India has a predominantly tropical climate ranging from the hot and humid climate in the east and north eastern states, hot and dry climate of the central and western Indian plains, to the cold climate in the northern regions. Orientation of buildings to direct sunlight and to prevailing wind direction is an important factor to be considered in the tropics where temperatures in the shade can reach as high as 45°C. Orientation of Buildings In very hot climate buildings will have to be cooled in summer by artificial means. Nevertheless, even in hot climate, it is not always necessary to use extensive artificial cooling. Some natural cooling is possible by building orientation and design. The design of the buildings can be carefully planned to derive maximum natural cooling and thus reduction in energy consumption. Natural ventilation aided by forced air circulation by fans is adequate in most instances, with recourse to air-conditioning only where inescapable.

66. Planning the Hospitals Dept of Biomedical Engineering,VCET 66 Artificial Ventilation Where air-conditioning is considered necessary, the design of the building will have to be as compact as Possible. Air-conditioning is the process of treating air to control all or some selected parameters viz . temperature, humidity, pressure, air movement pattern, air velocity and air cleanliness. The cost of air-conditioning has direct relationship with the volume of the building. Therefore, the aim should be to restrict air-conditioning to the minimum and only where inescapable. This is achieved by resorting to keeping the volume of the buildings low by low ceilings and restricting the size of the rooms to the absolute minimum. However, certain areas of the hospital should always need airconditioning . These are the operation theatre, labour room, postoperative recovery ward, premature nursery and accident and emergency department/ward and ICU.

67. Planning the Hospitals Dept of Biomedical Engineering,VCET 67 Project Administrator and Coordination With so many interests involved (like clinical disciplines, architects, utility engineers and other specialist advisers from time-to-time), the project administrator has to take charge of coordinating the design team. Constant interaction between “clients” and works professionals during briefing and design process at all stages is a feature peculiar to hospital planning. Project Cost The most common method of estimating hospital construction costs has been the “per bed” method, i.e. if the total cost of a 100-beded hospital has been Rs. 400 lakhs, the cost per bed is Rs. 4,00,000.The complexity of modern hospitals defies determining the cost by such a general method. Certain hospitals have extensive research functions, classroom and educational facilities may be required for some, there may be emphasis on extensive outpatient clinical facilities for others, and still others are exclusively inpatient hospitals. Not only the range of services provided by one hospital may be vastly different from that of another, but also the gross areas per bed utilized by different hospitals will vary. General estimates based on comparison of costs are, therefore, difficult to make on a per bed or per square foot basis.

68. Planning the Hospitals Dept of Biomedical Engineering,VCET 68 Break-up of Project Cost The total cost of a hospital project can be broken down broadly as under: 1. Acquisition of site 2. Site survey, investigation 3. Landscaping 4. Construction contract—building with fixed equipment 5. Supervision and inspection 6. Equipping the hospital—diagnostic and therapeutic equipment 7. Movable equipment—furniture, etc. 8. Architect’s fees 9. Consultant’s fees 10. Site Engineers fees.

69. Planning the Hospitals Dept of Biomedical Engineering,VCET 69 EQUIPPING A HOSPITAL The mechanical and electrical installations and the plant and equipment component in a modern general hospital has been estimated to cost about 40 per cent of the entire hospital project out of which about half (20%) is required for medical equipment(s) of general use. Hospital equipment covers a broad range of items necessary for functioning of all the services. Various ways of classifying the equipment in hospitals can be used. However, for universal application the equipment in the hospital can be classified as: i . physical plant, ii. hospital furniture and appliances, iii. general purpose furniture and appliances, and iv. therapeutic and diagnostic equipment.

70. Planning the Hospitals Dept of Biomedical Engineering,VCET 70 Shake-down Period A well-planned hospital passes from the construction stage to the commissioning stage with a smooth transition if adequate thought has gone into aspect planning, equipment and staffing. After commissioning, a hospital’s staff, patients, community, buildings, facilities and environment interact and adjust with one another untill the hospital settles into its usual routine. The period from the time of commissioning of the hospital till it settles down into a satisfactorily functioning entity is the “shake-down period”. It is the period during which it experiences its teething troubles. In general, this period will be shorter if adequate time and thought have been devoted to planning and execution and can last from a few months to a year. Any necessity for additions, alterations and modifications will become apparent during this period, as also the necessity to readjust staffing schedules.

71. Guiding principles in planning hospital facilities and service Dept of Biomedical Engineering,VCET 71 GUIDING PRINCIPLES IN PLANNING A hospital is responsible to render an essential service. In fulfilling this responsibility, hospital planning should be guided by certain universally acknowledged principles. The principles are useful irrespective of the level of planning, i.e. whether at the national level, state level or individual hospital level. These principles were developed in the context of the American system of hospitals but have relevance and usefullness to hospital planning in India, and they are as relevant today as they were over five decades ago.

72. Guiding principles in planning hospital facilities and service Dept of Biomedical Engineering,VCET 72 Patient Care of a High Quality Patient care of a high quality should be achieved by the hospital through adopting following measures. 1. Provision of appropriate technical equipment and facilities necessary to support the hospital’s objectives. 2. An organisational structure that assigns responsibility appropriately and requires accountability for the various functions within the institution. 3. A continuous review of the adequacy of care provided by physicians, nursing staff and paramedical personnel and of the adequacy with which it is supported by other hospital activities.

73. Guiding principles in planning hospital facilities and service Dept of Biomedical Engineering,VCET 73 Effective Community Orientation Effective community orientation should be achieved by the hospital through adopting following measures: 1. A governing board made up of persons who have demonstrated concern for the community and leadership ability. 2. Policies that assure availability of services to all the people in the hospital’s service area. 3. Participation of the hospital in community programmes to provide preventive care. 4. A public information programme that keeps the community identified with the hospital’s goals, objectives and plans.

74. Guiding principles in planning hospital facilities and service Dept of Biomedical Engineering,VCET 74 Economic Viability Economic viability should be achieved by the hospital through taking these measures: 1. A corporate organisation that accepts responsibility for sound financial management in keeping with desirable quality of care. 2. Patient care objectives that are consistent with projected service demands, availability of operating finances and adequate personnel and equipment. 3. A planned programme of expansion based solely on demonstrated community need. 4. A specific programme of funding that will assure replacement, improvement and expansion of facilities and equipment without imposing too much cost burden on patient charges. 5. An annual budget plan that will permit the hospital to keep pace with times.

75. Guiding principles in planning hospital facilities and service Dept of Biomedical Engineering,VCET 75 Orderly Planning Orderly planning should be achieved by the hospital through the following. 1. Acceptance by the hospital administrator of primary responsibility for short and long-range planning, with support and assistance from competent financial, organisational , functional and architectural advisors. 2. Establishment of short and long-range planning objectives with a list of priorities and target dates on which such objectives may be achieved. 3. Preparation of a functional programme that describes the short-range objectives and the facilities, equipment and staffing necessary to achieve them.

76. Guiding principles in planning hospital facilities and service Dept of Biomedical Engineering,VCET 76 Sound Architectural Plan A sound architectural plan should be achieved by the hospital through the following: 1. Engaging an architect experienced in hospital design and construction. 2. Selection of a site large enough to provide for future expansion and accessibility of population. 3. Recognition of the need of uncluttered traffic patterns within and without the hospital for movement of hospital staff, patients, and visitors and for efficient transportation of supplies. 4. An architectural design that will permit efficient use of personnel, interchangeability of rooms and provide for flexibility. 5. Adequate attention to important concepts such as infection control and disaster planning.

77. Guiding principles in planning hospital facilities and service Dept of Biomedical Engineering,VCET 77 Medical Technology and Planning Developments in medical technology are taking place so rapidly that now the use of sophisticated technology determines professional status. The diffusion of medical technology vis-a-vis shortage of resources constantly play on the minds of the planners. Even in western countries, “rational” planning for medical technology is an evasive subject. The workshop on problems of planning of health services in urban areas in Europe felt that rational planning is aided by a hospital hierarchy of specialisation , and by national review agencies which have strong links with similar agencies in other countries. Specialised coronary care units (CCUs) were introduced on the basis of clinicians’ opinions about the effectiveness of such units. The evidence is suggestive that the innovation had serious flaws but once CCUs were established, there was great resistance to formal controlled trials. Some studies suggest that admission to a CCU is no better than treatment at home. However, the professional as well as popular view of these units is so entrenched that it is often difficult to plan for the proper use of these expensive facilities.

93. Purchase of capital equipment Dept of Biomedical Engineering,VCET 93

94. Purchase of capital equipment Dept of Biomedical Engineering,VCET 94 Here Are Five Primary Characteristics Of Capital Equipment: 1. Cost Capital equipment  is generally any piece of equipment whose cost is beyond a preset mark. This “set mark” will vary depending on the  hospital . For instance, a small hospital may classify any equipment purchased at more than $1,000 as capital equipment. A larger hospital with enormous resources may classify  capital equipment  as those items purchased at more than $5,000. Capital equipment can be stand-alone or supplementary. That is, they may be able to function independently or they may need to be used in conjunction with other equipment items in order to fulfill a particular function. For instance, software purchased together with, and physically installed in, a piece of capital hardware equipment may be capitalized. Under this circumstance the "set mark" price becomes irrelevant for the software because without it, the hardware would be useless. However, if you later purchase separate software to improve the performance of the hardware, this software may be expensed if it is valued at less than the established "set mark" or capitalized if it costs more. Equipment items that do not meet the "set mark" price individually may sometimes be bundled together to meet or exceed that "set mark" threshold cost. An example of such could be chairs for a waiting room. Individually, they may only cost $250 each, far below a $1,000 set mark for capital equipment. However, when purchased together, a group of just twelve would represent a purchase price of $3000 and so qualify to be capitalized.

95. Purchase of capital equipment Dept of Biomedical Engineering,VCET 95 2. Durability Capital equipment items are durable. Any item that cannot be used for a whole year before it wears out or becomes obsolete should not be classified as capital equipment. Capital equipment items are not purchased to be sold or disposed of in the short term. Consumable and disposable items, even if they exceed the "set mark" threshold, cannot be considered as capital equipment. 3. Size Capital equipment has on most occasions been associated with large, bulky items. While this is not completely untrue, not all capital equipment devices are big. For instance, a stand-by generator for $15,000 is definitely capital equipment. However, a defibrillator that costs $1,200 may also qualify as a capital equipment item even though it consumes much less space and is much lighter than the generator. 4. Tangibility Capital equipment is also tangible and physical in nature. This means that it is material, can be touched, and it occupies space. It can be inventoried and tagged as an enduring asset. If an item is not tangible, it cannot be considered as capital equipment. 5. Use Life Capital equipment items generally have a long use life, but are not permanent. They depreciate over time and may deteriorate or become outdated. Working with a medical equipment distributor like CME Corp gives you access to our Biomedical Equipment Technicians (BMETs) who carry out  preventive maintenance and equipment repair  that ensures patient safety, maximum productivity, and a longer use life. Typically, capital equipment has a life expectancy of 1 year or more, can be indexed as an asset, and may be amortized over a period of 5 to 10 years.
