3. 3
what is HIS?
•HIS. Hospital Information System. One that supports all hospital
functions and activities such as patient records, scheduling,
administration, charge-back and billing, and often links to or includes
clinical information systems such as RIS. (Radiology Information
System )
•that part of a HIS in which computer systems are used as ICT-
tools(information and communication technology ) is referred to as
its
computer-supported part
•the remainder is being referred to as the
non-computer-supported part
•as a consequence, a hospital has a HIS from ...
the beginning of its existence on

4. 4
what is HIS?
•the question is not
whether a hospital should be equipped with a hospital
information system or not,
•but an appropriate question would be ...
whether the performance should be enhanced, for example,
by using state of the art ICT-tools
•HIS must consider all areas of a hospital:
wards
outpatient units
service units (diagnostic, therapy,others)
administrative departments
management/executive units

5. 5
what is HIS?
•HIS must consider all groups of persons
physicians
nurses
administrative staff
technical staff
health informaticians / health information managers
...
•... and last, but not least,
patients
visitors
suppliers

The information in hospital

10. 10
The information of the hospital come from
•Front office
•Doctors consultation room
•Ward
•Laboratory
•The service providers like financial and
insurance service provider
•And so on

Conclusions
•The system allows for interaction between the various
component in an integrated and modular format
•While creating a composite Master Patient Index
comprising of all kinds of financial,administrative and
clinical information, the system also serves to pass on the
message
•A technology that allows computers and networks to add
and extract value from information as the information
moves throughout an organization
•The information can be assigned, routed, activated and
managed through system-controlled rules that mirror the
decision processes of the business operations in the hospital

17. 17
The function of HIS

18. 18
•Laboratories
•Pharmacies
•Researchers
•Doctors and consultants
•Banks and financial institutions
•Administrators
•And knowledge managers
HIS have the ability to link the following
major players

19. 19

20. 20
•the aim of a HIS is
to adequately enable the execution of information processing
functions
– for patient care, including
administration as well as
– for research and education mainly
for university hospitals -
considering economic hospital management, as well as
legal and other requirements
•therefore HIS contributes to a high quality of patient care and
medical research

21. 21
•HIS should provide
information, primarily about patients, in a way that it
is correct, pertinent and up to date, in time, accessible
by the right persons at the right site in a usable format
knowledge, primarily about diseases, but also, for
example, about the effects of drug interaction, to
support diagnosis and therapy
information about the quality of patient care, hospital
performance and costs

22. 22
in other words:
•HIS should provide, as far as feasible,
the right information and
the right knowledge
at the right time
in the right place
to the right people
in the right form
•so that these people can make
the right decisions

23. 23
•university hospitals / university medical centers,
in addition to patient care
undertake research and teaching to gain medical
knowledge and deeper understanding
new knowledge is gained from specific
experiences in patient care through careful data
collection
to support this, also specialized biometric
methods, such as planning clinical trials,are needed

24. 24
ten application areas will be the necessary
part of the HIS
1.Admissions, Medical Records & Abstracting (ADM/MRI/ABS)
2.Billing/Account Receivable (BAR)
3.Community Wide Scheduling (CWS)
4.Data Repository (DR)
5.Imaging and Therapeutic Services (ITS)
6.Laboratory, Microbiology, Blood Bank & Anatomical
Pathology (LIS)
7.Order Entry & Electronic Medical Record (OE/EMR)
8.Patient Care System (PCS)
9.Pharmacy (PHA)
10.Remote Physician Access

25. 25
importance of HIS

26. 26
•the information system of a hospital is an important
quality factor
•the information system of a hospital is an important
cost factor
•the quality of HIS is becoming increasingly relevant in
the competition between hospitals
•a HIS can provide a holistic view of patients and of a
hospital
•a HIS can be seen as the memory and nervous system
of a hospital
