Process modification and emergency department radiology service

摘要

Our purpose was to demonstrate the impact of changes in technology, staffing, and departmental processes on service levels in emergency department (ED) radiology. We also attempted to determine if report turnaround time affects ED patient throughput. Radiology performance was evaluated before and after the modifications of processes integral to the interpretation of ED imaging. Picture archiving and communication system, voice recognition (VR), staffing, physical site, work flow, and administrative modifications were undertaken over ～2 years. The average time interval from the exam completion to report signature was 5,184 min (standard deviation (SD) of 1,858 min before the implementation of VR and other modifications of ED radiology processes). In post initial modifications, it was 150 min (SD, 169 min) and 157 min (SD, 215 min) in post additional modifications. The percentage of the signed written reports available in less than or equal to 60 min was 0%, 27%, and 40%, respectively. Ongoing improvements are needed to increase the service levels for ED radiology. Further improvement will require collaboration and adjustment with the ongoing assessment of metrics.
