What is a clinical information system (CIS)?

A CIS uses computers to manage clinical information. This information includes medical history and other relevant information, which helps health care personnel make decisions.
The information in a CIS is legible and accessible. The U.S. government states that these systems will lead to improved patient outcomes by improving decision making using computerized decision-support systems and reducing adverse drug events by eliminating handwritten prescriptions. Actual studies are divided on these questions. However, these systems are expensive to adopt, raise privacy questions, and may be resisted by doctors who believe that their workload will increase.
