The Effect of Daytime Surgical Hospitalists on Reducing Night Shift Physicians’ Workload

Abstract

Background The shortage of doctors at night makes it difficult to execute complex tasks and deliver accurate decisions. Therefore, reducing the night shift physician’s workload is essential for patient safety. This study aimed to observe the effect of daytime surgical hospitalists on the reduction in night shift physicians’ workload by analyzing the volume of electronic orders generated at night for postoperative patients. Methods A total of 9328 hospitalized patients who underwent colorectal or gastrointestinal surgery for more than 120 minutes were reviewed retrospectively. This study reviewed the nighttime volume difference of electronic orders between patients cared for by a daytime surgical hospitalist and patients cared for by a resident. Multiple logistic regression analysis was performed to analyze the risk factors of nighttime orders during hospitalization (dichotomous end point). Negative binomial regression analysis was also performed to analyze the volume of electronic orders as countable data, and the incident rate ratio was estimated (count end point). Results The risk of the occurrence of nighttime electronic order for patients treated by a surgical hospitalist was lower than that of patients cared for by a resident (adjusted odds ratio, 0.616; 95% confidence interval, 0.558–0.682; P < 0.001). In the negative binomial regression analysis, the total volume of electronic orders at night was lower in patients cared for by a surgical hospitalist than in patients cared for by a resident (adjusted incident rate ratio, 0.653; 95% confidence interval, 0.623–0.685; P < 0.001). Conclusions The introduction of daytime surgical hospitalists is associated with the lower workload of night shift physicians.
