Hospitals today have evolved to be a complex, interdependent and multi-disciplinary sector that is built around in order to provided highly and intensive care to community authorities. Almost all hospital or health care centers need a vast amount of information. When a patient admitted to the hospital, the first things physician or nurses need is the information of the patient. Later patient need the result from clinical, laboratory and radiology examination. All of this is the frequent diagnostic procedure in all hospital around the world.

For that purpose, hospital today are recognizing IT as a supportive arm to control all the system require in the hospital to serve patients in an efficient way and to enhance revenue and also to improve operational efficiency.

Computer used is the one that introduced in the hospital in order to:

Increase organizational efficiency

Store, exchange useful, accurate and timely information

Improve medical care to high quality services at reasonable cost.

Improved Management Information System; and reduce clerical error

Administrative workload by automating processes.

From that it was realized to create one system that is health information system specifically for hospital called Hospital Information System or HIS. This system streamline the essential function in the hospital by computerizing the process of retrieved patient information, collating and collecting data .In order to understanding of an HIS system ,two main word need to be master first that is ‘data’ and ‘information’.


A series of observation or measurement or fact.


A set of element working interactively to process input data

Information System:

A set of elements working interactively to gather input data and later to disseminate output information.

What is Hospital Information System (HIS)?

Hospital Information System is a set of component and procedures organized to generating information, manage administrative in order to improve health care management decision at all level of health system. hospital information system

The goal of this system is to use computer and communication equipment to collect, store, process and administrative information for all hospital activities to satisfy the functional requirement of all authorized users.

The main purpose of Hospital Information System is to use a technology network of computers to collect process and retrieve patient care and administrative information from various departments for all hospital activities to satisfy the functional requirement of the users.

Others purpose:

As a decision support system for the hospital authorities for developing comprehensive health care policies in health care sector.

Comprises an electronic patient record which forms the core of the system and links it to all other department in the hospital.

Centralize the information, so no duplication occurs.

Hospital authorities can access the case sheets, order tests and later prescribe medication. Doctors can maintain notes and surgery record in the operation theatre and laboratory.

In the early starting of HIS, it is consists with the large central computers connected to the terminals ,in the progressing of technology, the latest HIS is replaced by networked microcomputers to manage all the hospital medical care information.

HIS can utilize the power used of computer in medical care that provided a network of integrated computer in record and services to a patient in the hospital from one department such as laboratory ,blood bank, nursing, radiology, clinical ,inpatient ward, outpatient and so on to other department.

The software created for each department or process is called a module.

This module used to automate all the individual department, when all these module put together it will from HIS.

In general, there are two or more component consists in this Hospital Information System that are:

Clinical Information System (CIS)
