The Effect of Emergency Medicine Residents on Clinical Efficiency and Staffing Requirements.

OBJECTIVES: The effect of emergency medicine (EM) residents on the clinical efficiency of attending physicians is controversial. The authors hypothesized that implementing a new EM residency program would result in an increase in relative value units (RVUs) generated per hour by attending physicians and decrease staffing requirements. METHODS: This was a retrospective observational analysis of an emergency department before, during, and after the establishment of a new EM residency program. We analyzed the change in RVUs billed, patients seen, and hours worked by attending physicians, midlevel providers (MLPs), and residents, and addressed potential confounding factors. RESULTS: The clinical efficiency of attending physicians increased by 70%, or 4.98 RVUs/hour (from 7.12 [SD ± 1.4] RVUs/hour to 12.1 [SD ± 2.2] RVUs/hour, p < 0.001) with the implementation of an EM residency program. Overall, net department RVU generation rose by 32%, even as attending physician coverage decreased by 6.3% (p < 0.05), and MLP coverage dropped by 60% (p < 0.05). We estimated that the implementation of the residency saved 4,860 hours of attending physician coverage and 5,828 hours of MLP coverage per year. This represents an estimated $1,741,265 in annual staffing savings, comparable to the residency program's annual operating cost of $1,821,108. CONCLUSIONS: The implementation of an EM residency program had a positive effect on the clinical efficiency of attending physicians and decreased staffing requirements.

A new electrocardiographic criteria for emergent reperfusion therapy.

The benefit of emergency reperfusion therapy with fibrinolytics or primary percutaneous coronary intervention in patients with ST-segment elevation (STE) acute myocardial infarction (MI) is well known. However, what is not well known are which subgroups of MI patients with ST-segment depression (STD) on the 12-lead electrocardiogram (ECG) may benefit from emergent reperfusion therapy. Current clinical guidelines recommend against administering emergent reperfusion therapy to MI patients with STD on the ECG unless a true posterior MI is suspected. Overlooked subgroups of patients with STD on the initial ECG who may potentially benefit from emergent reperfusion therapy are patients with multilead STD with coexistent STE in lead aVR. This finding has been reported in MI patients with occlusion of the left main artery, occlusion of the proximal left anterior descending artery, and MI in the presence of severe multivessel coronary artery disease. Because these patients have a higher mortality in the setting of MI, we believe that this ECG finding be considered a STEMI equivalent and that patients with this finding receive consideration for emergent reperfusion therapy preferably at a center with both primary percutaneous coronary intervention and coronary artery bypass grafting capability. In this report, we present 3 such patients to heighten the awareness of the emergency physician to this phenomenon.
