Hospital Information System A hospital information system (HIS), variously also called clinical information system (CIS) is a comprehensive, integrated information system designed to manage the administrative, financial and clinical aspects of a hospital. This encompasses paper based information processing as well as data processing machines. It can be composed of one or a few software components with specialty-specific extensions as well as of a large variety of sub-systems in medical specialties (e.g. Laboratory Information System, Radiology Information System). CISs are sometimes separated from HISs in that the former concentrate on patient-related and clinical-state related data (electronic patient record) whereas the latter keeps track of administrative issues. The distinction is not always clear and there is contradictory evidence against a consistent use of both terms.

A hospital information systems (HIS) is a computer system that is designed to manage all the hospital’s medical and administrative information in order to enable health professional perform their jobs j obs effectively and efficiently. Hospital information systems were first developed in the 1960s and have been an essential part in hospital information management and administration. Early systems consisted of large central computers connected to by dumb terminals, which are now being replaced by networked microcomputers. The systems were used









Hospital information systems now focus on the integration of all clinical, financial and administrative applications and thus could also be called an integrated hospital information processing systems (IHIPS). Components of a hospital information system consist of two or more of the following: Clinical Information System (CIS)  Financial Information System (FIS)  Laboratory Information System (LIS)  Nursing Information Systems (NIS) 









Advancement in computer technology and the development of information exchange standards such HL7 and DICOM, make the task administering and integrating such systems a little more easier. Benefits of Hospital Information System (HIS) A 1992 survey of executive nurses (Simpson 1992) listed these benefits:









Improved quality of documentation  Improved quality of patient care  Increased nursing productivity  Improved communications  Reduced errors of omission  Reduced medication errors  Reduced hospital costs  Increased nurse job satisfaction  Compliance with regulations of the Joint Commission on Accreditation of Healthcare Organizations (JCAHO)  Development of a common clinical database  Improved patient's perception of care 









A study conducted by Mannle and Gaylin in 1997 entitled Quantifying clinical benefits created by integrated hospital information systems: a cost-benefit model yielded these results: The four Veterans Health Administration pilot hospitals could expect to realize over $22.6 million in clinical benefits. Of the $22.6 million, benefits for inpatient services accounted for $9.4 million, and benefits for outpatient services accounted for $13.2 million. During the first year of implementation, factors of incomplete clinical workstation saturation, incomplete clinical workstation adoption, and incomplete user proficiency produce underutilization of the HIS, resulting in 25 percent lower clinical benefits than could be expected under optimal utilization. Despite this loss of potential benefits, in the first year of implementation, projected savings exceeded projected costs (for system development, hardware, software, installation, maintenance, and training) by $5.8 million. These results are conservative-sensitivity analyses suggest that the total projected benefits could be overestimated by 6 percent and underestimated by 47 percent. Net benefits of implementing the system are positive and substantial.











Nauright & Simpson in 1995 authored a paper entitled Front-line hospital staff from six hospitals rate benefits of hospital information systems . The results were of the study states: A total of 695 respondents from six hospitals described benefits related to the quality of care, interdisciplinary communication, and collaboration; these were realized to a greater extent and were more important than benefits related to costsavings.









Types of Hospital Information System

Centralized vs. Decentralized. This distinction is based on whether information is kept primarily in a central computer, or is distributed over a number of workstations or servers located around the hospital. There are variations on this; for example, a system may be

























Business Oriented vs. Patient Oriented. Though both these types of systems handle patient information, the orientation of the original designers may affect the procedures and general "character" of a HIS. Terminal vs. Workstation Oriented. Terminals and workstations are computer devices that often look very similar: both usually have a keyboard and a CRT display screen, and are often











Workstation-oriented systems can be either centralized or decentralized, because the processing power of the workstation gives
