The impact of dedicated physician staffing on patient flow and quality assurance parameters in an Air Force emergency department.

A retrospective audit of 17,028 emergency charts at USAF Medical Center, Scott was performed over two time periods to compare patient waiting times and selected quality assurance parameters with two methods of physician staffing. Phase 1 consisted of 4 months when the Emergency Department (ED) was manned with five physicians assigned only to that department. Non-departmental physicians supplemented the full-time staff. Phase 2 was the corresponding 4 months the following year when the ED was staffed with six emergency physicians, and non-emergency physician coverage was minimal. The difference in daily census between the two periods of time was not statistically significant. The time required to be seen by a physician decreased from an average of 25.6 minutes per patient in phase 1 to 13.7 minutes per patient in phase 2. Time to disposition also decreased from 71.9 minutes per patient in phase 1 to 59.5 minutes per patient in phase 2. In the second phase the number of "positive" x-ray findings increased, while the number of incomplete charts and patients who left without being seen by a physician diminished.
