Hospital information system (HIS) is a section of health informatics that deals with the requirements of a hospital in the management. Modern hospitals use computer system that helps in managing all their information and allow efficiency of work in hospitals. The computer software in hospitals helps in monitoring patients’ admission, discharge, transfer and taking test results. HIS is basically the central unit of transaction in hospitals, all transactions like admissions, consultations, and registrations of patients. In addition, the system takes census and report in the management of the hospital; it records the number of patients, number of admissions and the financial report. In most hospitals, you find that the number of patients entering and exiting is high; taking records manually may cause inaccuracy. HIS aims at creating a paperless and conducive environment that cover all concepts of hospital operation. This system helps in keeping a common record of patients' history, this ensures the information is kept safe and controls those who access the information at different circumstances (Paré, Trudel, Jaana & Kitsiou., 2015). It enables the health care professionals to be attentive and bring care by being able to retrieve past records of the patients' health and the visiting records whenever it is needed. HIS benefits the healthcares in monitoring the usage of drugs that may lead to a reduction of unfavorable prescription of drugs to patients, while promoting the more appropriate utility of pharmaceuticals. The system enhances information efficiency and accuracy and helps in reducing duplication of information entries. Hospital software is an easier method to use especially when eliminating errors made by handwriting. This system makes administration simpler and accurate, the diet of patients and the distribution of medical aid is easily supervised. There is reduced documentation and filing since the use of paper is minimal. Use of information technology in healthcare has made it easier to access and retrieve patients' data and their transactions.
