Objective. The evaluation of the Hospital for Sick Children's Electronic Patient Chart (EPC) system was conducted to determine user satisfaction and perceptions, realized benefits, and the impact on physician practice and patient care.Methods. Clinical user surveys (18), semi-structured interviews (10), and analysis of chart viewing statistics.Results. In general clinical users are satisfied with the system. Four months post-implementation, the use of EPC had increased by over 300%, physicians increased the percentage of charts viewed for returning patients, and the number of hard copy chart requests decreased by 43%. The identified clinical issues included workstation locations, log-in security, and searching through charts. The Release of Information staff is also satisfied with the system but Health Records coding staff is not as EPC slows down their work.Conclusion. Although the EPC system has realized many benefits, the evaluation recommendations should be used to improve the EPC system and future implementations.
