Healthcare utilisation of patients with cholecystolithiasis in primary care: a multipractice comparative analysis

Abstract

Objectives To examine general practitioners’ (GP) management of cholecystolithiasis and to evaluate persisting abdominal complaints in the years after the diagnosis.Design Retrospective analysis of registry data and a subset of individual medical records.Setting Seventeen primary care practices affiliated with the Radboudumc Practice Based Research Network in the Netherlands.Participants 633 patients with cholecystolithiasis diagnosed between 2012 and 2016.Primary and secondary outcome measures The primary outcome of this study was the healthcare utilisation of patients with cholecystolithiasis diagnosed by the GP in terms of referrals to secondary care, laboratory diagnostics, prescribed medication and the prevalence of concomitant abdominal-related diagnoses in a time interval of 3 years before and 3 years after diagnosis of cholecystolithiasis. For secondary outcomes, electronic medical records were studied from seven practices to assess emergency department visits, operation rates and repeat visits for persistent abdominal symptoms. We compared the non-referred group with the referred group.Results In 57% of patients, concomitant abdominal-related diagnoses were recorded besides the diagnosis cholecystolithiasis. In-depth analyses of 294 patients showed a referral rate of 79.3% (n=233); 62.9% (n=185) underwent cholecystectomy. After referral, 55.4% (129/233) returned to the GP for persistent abdominal symptoms. Patients returning after referral were more often treated for another abdominal-related diagnosis before cholecystolithiasis was recorded (51.9% vs 28.8%, p<0.001).Conclusions The majority of patients in general practice with gallstones are referred and undergo cholecystectomy. Patients with concomitant abdominal-related diagnoses are likely to return to their physician. GPs should inform patients about these outcomes to improve the shared decision-making process before gallbladder surgery.
