Abstract
We examine the impact of emergency department (ED) treatment on future healthcare costs and outcomes. We postulate that ED physicians may a_ect patient outcomes through acumen in diagnosis and appropriate disposition conditional on diagnosis. We make use of a unique dataset and quasi-experiment on patients who seek treatment at an ED in Montreal, Canada. Physicians there rotate across shifts between simple cases and di_cult cases, implying that the assignment of patients will be quasi-random across physicians in an ED. We examine how the initial assignment of ED physician a_ects the use of resources during the initial ED visit and patient outcomes. We consider two serious, potentially life-threatening conditions, that present frequently in the ED, angina and transient ischemic attacks. We _nd that ED-costs (measured by physician-related costs and the number of procedures) and outcomes (from ED revisits to hospitalizations) vary across ED physicians practicing in the same ED. We also _nd a strong correlation of physician "practice style" (de_ned by a physician's average contribution to physician-related costs during the ED visit) across the two illness categories. Similarly, we _nd that physician "skills" (measured in revisits to EDs and hospitalizations), or lack there of, correlate positively across patient populations. Our results also suggest that physicians associated with costly practice styles are not associated with better outcomes. Finally, we _nd
that variations in diagnostic skills may be quantitatively more important than variations in
disposition skills.
