Hospital readmission after emergency room visit for cholelithiasis.

BACKGROUND: For patients presenting with symptomatic cholelithiasis, cholecystectomy is the definitive treatment modality. Our goal was to evaluate the surgical follow-up and outcomes in patients seen in the emergency department (ED) for an episode of symptomatic cholelithiasis and discharged home for elective follow-up.

METHODS: We performed a retrospective review of consecutive patients seen in the ED for cholelithiasis and discharged without hospital admission between August 2009 and May 2014. All patients were followed for 2 y from the date of the initial ED visit. We evaluated outpatient surgeon visits, elective and emergent cholecystectomy rates, and additional ED visits. Cumulative incidence and Kaplan-Meier curves were used to examine the time from the initial ED visit to outpatient surgeon evaluation and the time from the initial ED visit to ED readmission.

RESULTS: Seventy-one patients were discharged from the ED with a diagnosis of symptomatic gallstones. Patients who had an elective cholecystectomy in the 2 y after the initial visit were 12.6%. In this group, the mean time from the initial ED visit to outpatient surgeon follow-up was 7.7 d, and all elective cholecystectomies occurred within 1 mo of the initial visit. Of the 62 patients who did not have an elective cholecystectomy, only 14.5% of patients in this group had outpatient surgeon follow-up at mean time of 137 d from the initial ED visit for symptomatic gallstones. In addition, 37.1% of patients in this group had additional ED visits for gallstone-related symptoms, with 17.7% of patients having two or more additional ED visits, and 12.9% required emergent and/or urgent cholecystectomy. Additional ED visits (43.5%) occurred within 1 mo and 60.9% within 3 mo of their initial ED visit. In patients with additional ED visits for symptomatic cholelithiasis, 60.9% had more than one abdominal ultrasound or computed tomography scan during the course of multiple visits.

CONCLUSIONS: Failure to achieve a timely surgical follow-up leads to multiple ED readmissions and emergent gallstone-related hospitalizations, including emergency cholecystectomy. System-level interventions to ensure outpatient surgical follow-up within 1-2 wk of the initial ED visit has the potential to improve outcomes for patients with symptomatic biliary colic.
