BackgroundPatient-reported outcomes are important in the assessment of efficacy of intervention for ulcerative colitis (UC).AimTo compare the impact of interventions for moderate-to-severe UC on health-related quality of life (HRQL).MethodsWe searched Medline, Embase, CENTRAL and grey literature sources through October 2017. We included randomised controlled trials (RCTs) that compared infliximab, adalimumab, golimumab, vedolizumab or tofacitinib to each other or placebo. Outcomes included the change in quality of life scores and the proportion of patients with improvement in quality of life. We performed random-effect pairwise and network meta-analysis. We assessed confidence in estimates using the CINeMA (Confidence in Network Meta-Analysis) framework.ResultsFourteen RCTs assessed HRQL using the Inflammatory Bowel Disease Questionnaire (IBDQ) (14 trials), the Short Form questionnaire-36 (SF-36) (seven trials) or the European Quality of Life-5 Dimensions questionnaire (EQ-5D) (three trials). At induction (13 trials), low to very low confidence evidence suggested that all agents significantly improved both generic and disease-specific HRQL scores compared to placebo. However, only infliximab (MD 18.58; 95% CI 13.19-23.97) and vedolizumab (MD 18.00; 95% CI 11.08-24.92) showed clinically meaningful improvement in IBDQ score. Differences among individual interventions were imprecise. For maintenance (four trials), very low confidence evidence suggested that vedolizumab, tofacitinib and adalimumab maintained improvement in HRQL.ConclusionsInduction treatment with infliximab, adalimumab, golimumab, vedolizumab or tofacitinib improves quality of life compared to placebo. Evidence on maintenance therapy is sparse and uncertain. Head-to-head comparisons could enhance confidence in conclusions about differences between drugs in terms of HRQL.© 2018 John Wiley & Sons Ltd.
