Physician turnover effect for in-hospital cardiopulmonary resuscitation: a 10-year experience in a tertiary academic hospital.

Abstract

Controversy exists as to whether the physician turnover affects patient outcome in academic hospitals. In-hospital cardiopulmonary resuscitation (CPR) is an important indicator of in-hospital mortality. This study aimed to investigate whether the physician turnover is associated with the in-hospital CPR rate. This retrospective cohort study was conducted at a single center; all in-hospital CPR cases among in-patients from 1 January 2007 to 31 December 2016 were analyzed. The turnover period was defined as the changeover of the trainee workforce in March, May, and November. The primary outcome was any variation in the monthly in-hospital CPR events (per 1000 admissions). The secondary outcomes were return of spontaneous circulation (ROSC), CPR in intensive care unit (ICU), monthly in-hospital deaths per 1000 admissions, and average length of hospital stay. A total of 2182 in-hospital CPR cases were included in the analysis. Monthly in-hospital CPR rates were greater during the turnover period when compared to the non-turnover period (4.66±1.02 vs. 4.18±1.56, P=0.027). There was no significant difference in ROSC rate, CPR in ICU rate, monthly in-hospital deaths per 1000 admissions, or average length of hospital stay between the two periods. Our findings indicate that physician turnover may be associated with in-hospital CPR rate. However, physician turnover was not associated with ROSC rate, rate of CPR in the ICU, in-hospital death, or length of hospital stay.
