Physician hand-offs in other contexts have been associated with worse patient outcomes, presumably through communication gaps. We aimed to determine the association between attending physician hand-offs on CTUs and patient outcomes including escalation of care, readmission and mortality.Methods: We conducted a retrospective, multicentre cohort study using data from 3 tertiary care hospitals in Calgary between Jan. 1, 2015, and Dec. 31, 2017. We included hospital admissions in the top 10 case-mix groups. Our exposure variable was the number of attending physicians seen by a patient. Outcome measures were admission to intensive care unit (ICU); inpatient 7- and 30-day mortality; and 7- and 30-day readmission rate. We used multivariable regression statistical models adjusted for patient age, sex, length of stay, Charlson Comorbidity Index, case-mix groups, senior resident presence, team handovers and team transfers.Results: Our cohort included 4324 unique patients. There were no significant differences in the odds ratios (ORs) of admission to ICU, inpatient 7- and 30-day mortality, and 7- and 30-day readmission rates among 1 or 2 physicians. However, we noted a significant increase in 30-day readmission rate (OR 1.37, 95% confidence interval 1.05–1.78) in patients who had 3 or more attending physicians compared with those who had 1 attending physician.Interpretation: We found that 2 or more physician hand-offs on CTUs had a modestly greater association with patient readmission at 30 days. More research is needed to explore this finding and to evaluate associated patient and resource outcomes with physician hand-offs. ER -
