Cost of care in the emergency department: impact of an emergency medicine residency program.
OBJECTIVE
To evaluate the impact of an emergency medicine residency training program on the cost of care in the emergency department.


METHODS
A retrospective chart review was conducted of all ED encounters for a three-month period, six months before and six months after the introduction of an emergency medicine residency program into an urban community hospital. Physician staffing of this ED before the residency period was by nonemergency medicine residency-trained emergency physicians.


METHODS
A 27,000-visit-per-year urban community hospital ED. TYPE OF PATIENTS: A consecutive sample of all patients discharged home from the emergency center with one of six diagnoses. The diagnoses studied were viral upper respiratory infection, pharyngitis, acute asthma, seizure, lumbosacral strain, and cervical strain.


METHODS
Frequency of laboratory test and radiograph ordering pertinent to the evaluation of each diagnostic category were used as a marker of cost of care.


RESULTS
The presence of the residency training program did not increase the cost of care as measured by test use and, for three of the six diagnoses, actually lowered the cost of care. This effect was most prominent in the evaluation of lumbosacral and cervical strain when the residency physicians ordered radiographs at a rate five and 2.3 times lower, respectively, than the previous group and in the approach to pharyngitis when they ordered throat cultures 2.8 times less frequently.


CONCLUSIONS
As measured by selected test use for six common discharge diagnoses, the introduction of an emergency medicine residency program did not increase the cost of care in this urban community hospital ED.
