The demand for quality of care is ever increasing. The perioperative surgical clinic is one of the key components in improving the quality of care through identification, risk stratification, and management of the patients going through elective surgeries. Perioperative surgical clinic is a concept that has existed for a long time that is implemented in various ways. To help its operation, the perioperative surgical clinic utilizes a patient management system. However, the current usability relies on a software engineer's perspective rather than the actual users. This project reports a usability inspection of the current system through heuristic evaluation by actual users. After evaluation, potential remedies were suggested to the vendor for further improvements in the system.
