description: This doctoral dissertation comprises two independent essays on healthcare delivery analytics. In the first essay, we investigate the impact of task switching on three angles of emergency department (ED) operations: physician productivity, quality of care, and patient routing using comprehensive data of patient visits and lab tests. We find that a 10% increase in the switching frequency of physicians reduces the number of patients treated per hour by 8.65% - 11.53% on average. However, we find no significant influence on treatment quality. We propose an easily implementable data-driven queue management method to optimally partition patients into two queues to minimize switch cost. Further simulation shows that this method can reduce average waiting time by 38%. In the second essay, we study how surgical and cleaning teams adaptively adjust the service speed in response to real-time deviations from the planned schedules and the further impact on surgical quality. Using a unique surgery data set, we unveil that surgical and cleaning teams speed up when they fall behind schedule and slow down when they get ahead of schedule, with a stronger slowdown effect. We further show that a faster-than-scheduled surgical procedure erodes quality by increasing 30-day readmission and reoperation probabilities. Through a counterfactual analysis, we obtain a convex relationship between readmissions/reoperations and end-of-shift times.
