INTRODUCTION: Data from an operating room information system (ORIS) indicated that only 26% of scheduled first cases start on-time. A recent report has indicated that data feedback systems are currently being introduced to improve medical and surgical outcomes.  The purpose of this study is to determine if the implementation of a daily data feedback system would increase the percentage of scheduled cases starting on-time.
METHODS: The newly implemented data feedback system consisted of a daily data collection form which indicated the scheduled start time and actual start time for the first cases of the day. Other data included names of the attending anesthesiologist, attending surgeon, and the reason for delay (e.g. patient, anesthesiologist, surgeon, or nursing late). Within each category, detailed information was also obtained (e.g. premedication needed, no consent, equipment delays, etc.). This data collection form was posted on a public bulletin board located at the entrance to the PACU and near the surgical dictation station. Data was collected by the anesthesiologist. The ORIS data was analyzed before and after implementation of the new data feedback system. Statistical analysis was performed using Pearson Chi square test with p<0.05 considered significant.
RESULTS: A total of 286 first cases scheduled in the Children's Hospital Operating Rooms were analyzed. All cases were elective ASA 1-3 patients aged 1 day to 15 years. Data were analyzed from the ORIS for 2 months prior to initiation of the new feedback system and compared to data obtained 2 months after implementation of the new data feedback system.
As can be seen in Figure 1, there was a significant increase in the percentage of first scheduled cases that started on time (p=0.001) or were delayed only 1-15 minutes (p=0.04). There were no changes in delay times greater than 15 minutes.
CONCLUSIONS: Introduction of a daily data feedback system can lead to increased efficiency of operating rooms.
