Hospital Information System

Hospital Information System Definition Hospital Information System is an integrated, computer-assisted system designed to store, manipulate, and retrieve information concerned with the administrative and clinical aspects of providing services within the hospital CEN/TC 251 /PT001 Medical Informatics-Vocabulary First Draft Working Document

Hospital Information System Another definition A Hospital Information System (HIS) can be defined as an open system which attempts to integrate and communicate the outside and inside flow of information within a hospitaland provide the functions common for all applications.

Description of a Hospital Information System in terms of the main Information Entities Clinical subsystem: patient central Patient-Record Medical information Medical-administrative information Diagnostic laboratory radiology nuclear medecine EEG, ECG, EMG, respiratory. Therapeutical operation history radiotherapy intensive care physiotherapy nursing medication Admission data Patient demographic data Orders Planning and appointment data Patient diets Material deliveries Hospital : Communication system - Repository system General accounting Accounts receivable Accounts payable Personnel data Loans and salaries Budget control Inventories Case mix Resource allocation data Simulations/Models Retrospective utilization data Cost/Quality information Financial information Strategic information Management subsystem : hospital central Hospital Record

Objectives of A Hospital Information System The most important goals of HIS are: *To have a common registration of total patient information at the point of each transaction *To have the possibility to access information from any location at any time *To recognise the health care provider as major user and thus ease of use *To recognise integration as a “conditio sine qua non” *To recognise that a HIS must be cost efficient. *To provide tools for evaluating health care costs and quality *To recognise the clinical communications hub of a HIS *To recognise that technology must meet the user’s and applications needs *To establish the basis for hospiatl controlled and developed applications *To guarantee backward compatibility of new software releases *To guarantee high availability of the system

A modern HIS includes the following modules: Patient record Admissions/discharge/transfer Order entry/results reporting Drug profile Care planning Personnel/staff planning Financial

1. Patient Record The critical elements of a patient record-handling system are: Access control functions Input and presentation functions Document-handling functions Information-handling functions Electronic mail functions Help functions Communications functions Functions for follow-up of the activities

2. Admissions/Discharge/Transfer (ADT) Outpatient Care Modules Scheduling of appointments with physicians and nurses Registration of the visit Financial functions Statistics Data transfer to the hospital financial system Inpatient Care Modules Waiting list Preadmission data Admission and discharge Diagnosis Hospital statistics Data transfer to the hospital financial system

3. Order Entry/Results Reporting There are two subsets to the order system: a. Order Entry System: includes all orders for a patient and links that system to the hospital financial routines b. Referral Reply System:- the order for a procedure or an examination connected with an appointment scheduling module - checks that all referrals are handled and the results signed and included in the patient record

4. Drug Profile Drug Information Systems: is relevant to both inpatient and out patient care may include modules for retrieving information about drugs as well as for indicating what drugs a patient is using at a given moment provide formulations for specific prescriptions allow data manipulation link to the hospital financial system

5. Care Planning Care Information System for: giving every patient an individual care plan and following it up also contain functions that assist in selecting the appropriate care plan evaluating follow-up manipulating data for further analysis and study

6. Personnel/Staff Planning These systems : handle individual unit requirements in assigning staff provide follow-up reports assist in daily planning for staff allocation link to the hospital financial routines

7. Financial Each individual local unit needs routines for planning financial transactions and for evaluating their effectiveness Linkages with the main financial system eliminate the need to duplicate data input and to refer to separate systems

Implementation of HIS Implementation issues that must be addressed when satisfactory installing a hospital information system: Access Control System Patient Identification System Patient Admission, Discharge, and Transfer System Data Communications Standards
