Emergency Department Utilization Following Hepatopancreatic Surgery Among Medicare Beneficiaries

Background Care delivered in hospital-based emergency departments (ED) is a target for cost savings. ED utilization following hepatopancreatic surgery remains poorly defined. We sought to define the rate of ED utilization following liver and pancreatic resection, as well as to identify factors associated with ED visits post-discharge. Methods The Medicare 100% Standard Analytic Files were used to identify Medicare beneficiaries who underwent hepatectomy or pancreatectomy between 2013 and 2017. Claims associated with ED services were identified using the relevant Revenue Center Codes. Patient characteristics and postoperative outcomes associated with ED care within 30 days of discharge were investigated. Results Among 37,707 patients who underwent hepatopancreatic surgery, 10,323 (27.4%) had at least one ED visit within 30 days of discharge. Patients presenting to the ED were more likely to be male (OR 1.13, 95%CI 1.07-1.18). Patients undergoing a pancreatectomy (OR 1.39, 95%CI 1.32-1.47), as well as patients who had a perioperative complication (OR 1.16, 95%CI 1.10-1.23) and patients not discharged home (OR 1.41, 95%CI 1.33-1.49), were more likely to require ED care. In contrast, patients undergoing resection for cancer or surgery for an elective basis were less likely to present to the ED postoperatively (OR 0.92, 95%CI 0.87-0.97 and OR 0.22, 95%CI 0.20-0.23, respectively). Patients often had multiple ED visits within 30 days of discharge as 37.2% of patients presented to the ED with at least 2 visits. Visits were also most common in the immediate postoperative period, with 30.9% of ED visits taking place in the first 2 days from discharge. Among patients requiring postoperative ED care, 53.9% were readmitted within 30 days. Conclusion More than 1 in 4 patients undergoing hepatopancreatic surgery presented to the ED within 30 days of discharge, with most patients returning to the ED within the first week of discharge. A subset of patients had multiple ED visits. Future efforts should target patients most likely to be high ED utilizers to avoid the need for early post-discharge ED use.

Automated summary

More than 1 in 4 patients undergoing hepatopancreatic surgery presented to the emergency department within 30 days of discharge, with most patients returning within the first week post-discharge, and a subset of patients having multiple ED visits. Efforts should target those most likely to be high ED utilizers to prevent early post-discharge ED visits.
