This report summarizes the hospital information system (HIS) used at Universiti Kebangsaan Malaysia Medical Centre (UKMMC). The main system is the Patient Management System (PMS) which stores information on all patients. Other key systems include the Pharmacy Information System, Radiology Information System, and Research Management System. The objectives of HIS are to improve efficiency, quality of care, data sharing, and support research. While HIS provides benefits, there can be drawbacks related to development, implementation, user expectations, and post-implementation. Suggestions are made to improve systems like implementing an e-Pharmacy application.
