OBJECTIVE: Especially in emergency departments (EDs), a lack of internal medicine
(IM) residents in charge causes difficulties in medical care and ED overcrowding.
Thus, protocols without IM residents in EDs is needed. This study aimed to
investigate changes in medical care when emergency medicine residents replaced
the roles of IM residents. METHODS: This study was conducted at a single-site ED
of a university medical center. The study group contained patients admitted to
the IM department between September and December 2015, during which IM residents
were absent in the ED. The control group contained patients admitted to the IM
department between September and December 2014, during which IM residents were
present in the ED. Changes in medical care between the presence and absence of IM
residents in the ED were studied by comparing admission rates from the ED, length
of ED stay, duration of hospitalization, and concordance of diagnoses between
admission and discharge by the IM department. RESULTS: The study group contained
2,341 patients; the control group contained 2,215 patients. Admission rates from
the ED increased by 53.4% (95% confidence interval [CI], P<0.001); lengths of
stay decreased by 15.1% (95% CI, P<0.001); and durations of hospitalization in
the pulmonology department decreased by 38.4% (95% CI, P=0.001). Concordance of
diagnoses between admission and discharge decreased by 14.2% in the cardiology
department (95% CI, P=0.021). CONCLUSION: Lengths of stay were reduced without
critical declines in diagnostic concordance rates when emergency medicine
physicians, instead of IM residents in the ED, decided upon admissions of IM
patients.
