Stratification of inflammatory bowel disease outpatients by disease activity and risk of complications to guide out-of-hospital monitoring: a patient-centred quality improvement project

BACKGROUND: Inflammatory bowel disease (IBD) is a chronic relapsing-remitting condition affecting 600 000 people in the UK. Traditionally, patients attend outpatient clinics for monitoring regardless of their symptoms or risk of developing complications. This can lead to a mismatch between need and access: patients in remission given elective appointments displace those in need of urgent specialist attention. Novel initiatives implemented in the UK to improve outpatient monitoring have often required a well-maintained patient registry, empowered patients and significant information technology support. DESIGN AND STRATEGY: In this large-scale quality improvement project at St Mark’s Hospital, a tertiary centre for IBD, we stratified over 1000 patients attending three non-complex IBD clinics over 12 months according to disease activity and risk profile. The aim was to offer a choice and subsequently transfer 50% of eligible patients to specialist nurse-led telephone clinics and demonstrate non-inferior satisfaction levels to existing outpatient follow-up. We also sought to ensure there was timely access to a newly established rapid access clinic for patients requiring urgent specialist attention. A core project team consisting of healthcare professionals, patients and quality improvement scientists met regularly. The team tested and scaled up interventions using ‘Plan-Do-Study-Act’ cycles within the ‘Model for Improvement’ framework and analysed data continuously using statistical process charts. RESULTS: Over 12 months, the average number of eligible patients transferred to telephone clinics rose from 17.6% (42/239) using a questionnaire method to 59.3% (73/123) using active discussion in clinic. Patient satisfaction scores remained high and non-inferior to baseline scores in face-to-face clinics. The median waiting time to be seen in the rapid access clinic was 6.5 days. CONCLUSION: This is the first published study to report on the successful stratification of patients with IBD based on disease activity and risk of complications to create a more responsive, sustainable and patient-centred model for IBD monitoring.
