Abstract Background Managing fatigue, pain and urgency/ faecal incontinence (FI) represents a key unmet need in holistic treatment of IBD. The IBD-BOOST programme was a 5-year programme evaluating the burden and treatment of these symptoms. Methods A national survey was conducted 1, followed by development and feasibility testing of a checklist for nurse-led optimisation of modifiable causes of symptoms 2. Following this, IBD-BOOST, a digital, interactive, facilitator-supported, self-management intervention to address fatigue, pain and FI was assessed in a multi-centre, two-arm, parallel-group, randomised controlled trial 3. The web-based programme combined educational, behavioural and cognitive strategies delivered through a cognitive behavioural framework. Patients who rated impact of fatigue, pain, and/or FI as ≥ 5/10 in the national survey were invited. The intervention was 6 months access to the online IBD-BOOST programme supported by a facilitator; the control group received are as usual (CAU). Primary outcomes were UK Inflammatory Bowel Disease Questionnaire (UK-IBDQ) and global rating of symptom relief (GRSR) at 6 months. A cost-effectiveness analysis was performed. Results From the national survey (8486 responses; 54% reporting FI, 24% fatigue and 21% pain)1, 780 participants were recruited to the RCT. At 6 months, there were no statistically significant between-arm differences for UK-IBDQ (mean difference = -1.67 (95%CI = -4.13, 0.80), p = 0.19) and GRSR (mean difference = 0.44 (95%CI = -0.56, 1.44), p = 0.39), but positive trends across outcomes were observed. Engagement with the programme was variable, with 57% of participants completing the minimum “dose” of four sessions. Importantly, complier-averaged causal effects analysis demonstrated that participants who complied with the intervention reported better UK-IBDQ scores than ‘would-be’ compliers receiving CAU alone (mean difference = -2.39 (95%CI = -4.34, -0.45), p = 0.02). Serious adverse events were similar between the intervention and CAU. The intervention was found to be cost-effective, improving generic health-related QoL (EQ-5D-5L) with high probability (90%) of being cost-effective at conventional willingness-to-pay thresholds. Cost savings were -£28,633 (95% CI: -51,555; 18,764) and -£33,568 (-64,421; 26,198) per QALY gained with IBD-BOOST from health services and societal perspectives, respectively. Conclusion The IBD BOOST programme represents an in-depth body of work in holistic IBD care. The RCT is the largest trial of a psychological intervention in IBD fatigue, pain and FI. Although the primary outcome endpoints were not met, patients who engaged with the intervention derived benefit and the intervention was cost-effective. References: 1.
