Emergency department overutilization following cholecystectomy and inguinal hernia repair.

backgroundEmergency Department (ED) utilization following general surgery procedures is poorly understood and places immense strain on the healthcare system. Inefficient ED utilization is responsible for up to $38 billion in wasteful spending annually. Nearly 56% of ED visits may be avoidable. The aim of our study was to quantify ED utilization following elective cholecystectomy (CCY) and inguinal hernia repair (IHR), to characterize the impact and identify causes. MATERIALS AND

methodsThis retrospective study included patients across eight hospitals in a single health system undergoing elective CCY and IHR between January 2018 to June 2019. Patients who returned to the ED within 30 and 90 days were analyzed for hospital readmission, preventability (based on the Goldfield criteria), relation to index surgery and clinician communication within 48 h of presentation.

resultsIn total, 3678 patients had elective surgery in this timeframe. Of these, 476 patients (13.1%) visited the ED at least once within 90 days from their surgical admission discharge date and 114 were readmitted to the hospital (23.9%). Average length from discharge to ED presentation was 27.1 days. The mean cost associated with these ED visits was $974 per visit. 31.9% communicated with their clinician within 48 h of ED presentation. 73.9% of ED visits occurred between Monday - Friday and 51.5% took place between the hours of 8 am-5 pm. 46.6% of ED visits were related to the index operation and 40.7% of ED visits were deemed preventable.

conclusionsWhile hospital readmissions have been scrutinized in the literature, relatively little is known about postoperative ED utilization. Our study is one of the first to document postoperative ED utilization up to 90 days after surgery. For just two common elective general surgery procedures, we found these visits were financially burdensome and led to ED discharge in > 75% of patients. Numerous opportunities to improve care were identified. Most ED visits occurred on weekdays and during daylight hours, suggesting an opportunity to utilize outpatient clinics in lieu of the ED. Nearly 50% were related to the operation and nearly 40% were preventable. Revamping the discharge instructions and post-discharge communication-including novel strategies leveraging telemedicine-by providers has the potential to dramatically decrease postoperative ED utilization.
