Indicators for measurement of health including mortality, morbidity an d disability

1. Indicators of Health By Dr. Madhusudan Swarnkar Assistant professor Dept. of Preventive and Social Medicine Jhalawar Medical College, Jhalawar

2. Health: Health is defined as “ a state of complete physical, mental & social wellbeing, and not merely an absence of disease or infirmity” (WHO) Health cannot be measured in exact measurable forms Hence measurement have been framed in terms of illness (or lack of health), consequences of ill-health (morbidity, mortality) & economic, occupation & domestic factors that promote ill health

3. Indicators of Health: Indicator also termed as Index or Variable is only an indication of a given situation or a reflection of that situation Health Indicator is a variable, which help to measure changes and over time they indicate direction and speed of changes On direct measurement, they reflects the state of health of persons in a community.

4. Use of indicators Indicators are required to measure health status of community Also to compare health status of one country with that of another For assessment of health care needs For allocation of scarce resources Monitoring and evaluation of health services, activities and programs To measure the extent to which the objectives and targets of program achieved

5. Characteristics of indicators: for ideal indicators Should be valid , they should actually measure what they are supposed to measure, Should be reliable and objective , the answer should be the same if measured by different people in different situation, Should be sensitive , they should be sensitive to changes in the situation concerned, Should be specific , they should reflect changes only in the situation concerned, Should be feasible , they should have the ability to obtain the data needed and; Should be relevant , they should contribute to the understanding of the phenomenon of interest.

6. Classification : Mortality indicators Morbidity indicators Disability rates Nutritional status indicators Health care delivery indicators Utilization rates Indicators of social and mental health Environmental indicators Socio economic indicators Health policy indicators Indicators of quality of life Other indicators

7. Mortality indicators Crude death rate: Expectation of life: Infant mortality rate Child mortality rate: Under-5 proportionate rate: Maternal (puerperal) mortality rate: Disease specific mortality: Proportional mortality rate

8. Mortality indicators - Crude death rate: Number of deaths per 1000 population per yr. in a given community, It indicates the rate at which people are dying. It provides a good tool for accessing the overall health improvement in a population. Usefulness of CDR is restricted b/c it is influenced by the age sex composition of the population. A decrees in death rate indicates towards overall health improvement of community. CDR = Total no. of deaths in an area during a given year Mid year population in the same area and year x1000

9. Maternal mortality rate “The death of a women while from pregnant or within 42 days of termination of pregnancy, irrespective of the duration and site of pregnancy, from any cause related to or aggravated by the pregnancy or its management but not from accident or incidental causes.” Expressed as a rate per 1000 females in reproductive age group . MMR = Total no. of female deaths due to complication of pregnancy, childbirth or within 42 days of delivery from puerperal causes in an area during a given year Total no. of females in reproductive age group in the same area and year X 1000

10. Mortality indicators- MMR…… MMR strongly reflects the overall effectiveness of health system. The low status of women in the society coupled with their low literacy levels prevents the women from taking antenatal care even if services are available There is inverse relationship b/w life time risk of maternal death and the availability of the trained health worker during pregnancy and at the time of delivery. Enhancing women’s access to family planning, adequate nutrition and affordable basic health care would ↓ rate further. 11-17 % maternal deaths occur during child birth while 50-70% in postpartum period. About 45% of postpartum maternal deaths occur during the 1 st 24 hrs.

11. perinatal mortality rate No. of foetal deaths of > 28 weeks gestation plus infant deaths of < 7 days age in a defined area in one year per 1000 live births > 28 weeks gestation in the same area and in the same year. PMR is a combination of stillbirths and neonatal deaths. It is good indication of the extent of pregnancy wastage as well as quality and quantity of health care available to the mother and the newborn. PMR in India for the year 2011 was 31/1000 live births. PMR = Late foetal deaths(28 weeks gestation and more or 1000gm. or more weight at birth) + early neonatal deaths (1 st week) in an area during a given year Total no. of live births (weighing over 1000 gm. At birth) in the same area and year x1000

12. Neonatal mortality rate Neonatal deaths are deaths of newborn commencing at birth and upto 28 completed days after birth . Early neonatal deaths ( upto 7 days after birth) Late neonatal deaths ( from 7days after birth to 28days after birth) Neonatal mortality is directly related to birth weight and gestational age. Main causes of neonatal mortality are intrinsically associated with the health of mother and cares she receives before, during and immediately after birth. NMR = Total no. deaths of children under 28 days of age in an area during a given year Total no. of live births in the same area and year x1000

13. Infant mortality rate…. Infant mortality rate : it is ratio of deaths under 1 yr of age in a given yr to the total no. of live births in same yr; expressed as a rate per thousand live birth. It is a sensitive indicator of the availability, utilization and effectiveness of health care, particularly perinatal care. It is universally accepted indicator of health status not only infants, but also of the whole population and of the socioeconomic conditions under which they live. India still among high IMR countries, 40/1000 LBs. in 2013 (while 47/ 1000 LBs. in world). Madhya Pradesh, Orissa and UP still having IMR above 70 (while in Rajasthan and Assam it is 67).

14. Child mortality rate Child mortality rate: no. of deaths at ages 1-4 yrs in a given yr, per 1000 children in that age group at mid-yr. it excludes infant mortality. It is related to inadequate MCH services, insufficient nutrition, low coverage by immunization and adverse environmental exposure and other exogenous agents. Infectious diseases of childhood like measls , whooping cough, diphtheria, diarrhoea , and ac.resp . inf. Affect mostly this age group and lead to high mortality (particularly in malnourished). >8% of total deaths in Rajasthan, Bihar and U.P.

15. Under-5 proportionate rate, and under 5 mortality rate Under-5 proportionate rate: proportion of total deaths occurring in the ↓5 age group. High rate reflects high birth rates, high child mortality rates and shorter life expectancy. In communities with poor hygiene the proportion may exceed 60%. Under 5 mortality rate : annual no. of deaths children ↓ 5 yr of age, per 1000 live births. It measures the probability of dying b/w birth and exact 5 yrs of age. It is best single indicator of social development rather than GNP per capita.

16. Disease specific mortality When mortality rate were computed for specific diseases. It shows burden on community b/c of particular disease. It is total no. of deaths by a specified disease in a year and in particular area. Examples: deaths from cancer, accidents, cardiovascular diseases, diabetes, etc

17. Proportional mortality rate Simplest measure of estimating the burden of a disease in the community. Proportion of all deaths attributed due to diabetes/ MI/ Stroke/ cancer/ accidents etc Proportional mortality rate for communicable diseases indicates the magnitude of preventable mortality.

18. Morbidity indicators Incidence and prevalence Notification rates Attendance rates at out-patient department, health centers etc. Admission, readmission and discharge rates Duration of stay in hospital and Spells of sickness or absence from work or school

19. Health care delivery indicators a. Doctor-population ratio b. Doctor-nurse ratio c. Population-bed ratio d. Population per health/ subcentre e. Population per traditional birth attendant These indicators reflect the equity of distribution of health resources in different parts of the country and provision of health care.

20. Utilization rates Utilization of services/use of heath services or actual coverage expressed as the proportion of people in need of a service who actually receive it in a given period.(a yr.) Health care utilization is affected by factor such as availability and accessibility of health services and the attitude of an individual towards his health and the health care system. A relationship exists between utilization of health care services and health needs and status of population.

21. Utilization rates Proportion of pregnant women who receive antenatal care, or have their delivery supervised by a trained birth attendant. Proportion of infants who are fully immunized against the 6 vaccine preventable diseases. Percentage of population using various methods of family planning. Bed occupancy rate ( average daily in patients/average number of beds). Average length of stay(days of care rendered/discharge). Bed turn over ratio(discharges/average beds)

22. Nutritional status indicators Nutritional status is a positive health indicator. Three nutritional status indicators important as indicators of health status: Anthropometric measurements of preschool children:- weight, height and mid arm circumference; Height( and sometimes weight) of children at school entry and Prevalence of low birth weight (<2.5 kg.)

23. Indicators of social and mental health These include suicide , homicide, act of violence and crime, road traffic accidents, juvenile delinquency, alcohol and drug abuse, smoking, obesity, battered baby and battered wife syndromes; neglected and abandoned youth in the neighborhood. These social indicators provide a guide to social action for improving the health of the people.

24. Environmental indicators These reflect the quality of physical and biological environment in which diseases occur and I which people live. These are pollution of water and air, radiation, solid waste, noise, exposure to toxic substances in food and drinks. Most useful indicators are those measuring the proportion of population having access to safe water and sanitation, (percentage of households with safe water in the home or within 15 min. walking distance, adequate sanitary facilities in the home or immediate vicinity)

25. Socio economic indicators Rate of population increase Per capita GNP Level of unemployment Dependency ratio Literacy rate, especially female literacy rates Family size Housing: no. of persons per room Per capita calorie availability

26. Health policy indicators The relevant indicators are proportion of GNP spent on health services proportion of GNP spent on health related activities (including water supply and sanitation, housing and nutrition, community development) proportion of total health resources devoted to primary health care

27. Disability rates Event type indicators: Number of days of restricted activity Bed disability days Work loss days (or school loss days) within a specified period Person type indicators: Limitation of mobility: eg . Confined to bed/house, Limitation of activity: eg . limitation to perform the basic activities of daily living- (eating, washing, dressing, going to toilet, moving about), limitation in major activity (ability to work at job, ability to housework )

28. Disability rates Sullivan’s index (expectation of life free of disability): computed by subtracting from the life expectancy the probable duration of bed disability and inability to perform major activities. HALE (Health -Adjusted Life Expectancy) : measure healthy life expectancy, based on life expectancy at birth but includes an adjustment for time spent in poor health. DALY (Disability - Adjusted Life Year ): measure of burden of disease in a defined population and the effectiveness of the interventions. DALYs express years of life lost to premature death and years lived with disability adjusted for the severity of the disability.

29. Other indicators Social indicators : Population ; Family formation, family and households; Learning and educational services; Earning activities; Distribution of income, consumption and accumulation; Social security and welfare services ; Health services and nutrition ; Housing and it’s environment ; Public order and safety ; Time use ; Leisure and culture ; Social stratification and mobility Basic needs indicators : calorie consumption, access to water, life expectancy, deaths due to disease, literacy, doctors and nurses per population, GNP per capita Health for all indicators: Millennium development goal indicators :

30. Health for all indicators . Four categories of indicator given by WHO Health policy indicators Political commitment to heath for all Resource allocation The degree of equity of distribution of health services Community involvement Organizational framework and managerial process Social and economic indicators related to health Rate of population increase GNP or GDP Income distribution Work conditions Adult literacy rate Housing Food availability Indicators for the provision of health care Availability Accessibility Utilization Quality of care Health status indicators Low birth weight (%) Nutritional status and psychological development of children Infant mortality rate Child mortality rate(1-4) Life expectancy at birth Maternal mortality rate Disease specific mortality Morbidity – incidence and prevalence Disability prevalence
