The VEPSER system is a web-based application that facilitates voluntary reporting of patient safety events. It allows healthcare providers to submit safety event reports and includes tools for quality managers to analyze reports, identify root causes, and track follow-up actions. The system guides users through the reporting process, integrates with external data sources, and generates reports that comply with the AHRQ Common Formats standard. It also includes a report designer interface to customize existing reports or create new ones.
