Hospital Information Systems (HIS) are computers that help hospitals keep track of information about their patients, staff, and other important data. The system helps to make sure that patients are getting the best care, and that the hospital staff is working efficiently and safely. Hospitals use the HIS to store and retrieve everything from patient records to lab results. It also helps hospital staff monitor and report on patient progress, keep track of finances, and improve patient safety. The HIS also lets doctors and nurses access data quickly and securely so that they can make informed decisions about patient care.
