The impact of Recovery College enrolment on health service use and patient outcomes: retrospective matched cohort study using routinely collected data

BackgroundRecovery Colleges (RCs) support recovery through adult education, with preliminary evidence of positive effects on a range of outcomes. This study examined associations between RC enrolment and mental health service use at an index mental health provider, use of other National Health Service (NHS) hospital services for all causes, associated costs, and service user outcomes. MethodsOur retrospective matched cohort study used a controlled before-and-after design. We used linkage with electronic health records to identify all mental health service user students enrolled at one RC. Students were matched with non-student service user controls on sociodemographic and clinical variables using caliper matching. Impacts of RC enrolment on service use were assessed using negative binomial regression models at six-month, 12-month, and five-year post-enrolment. People with lived experience were involved in the design, conduct, and reporting of this study. OutcomesOur sample comprised 1 435 students and 4 665 controls. We observed decreases in several types of mental health service use in students relative to controls at six months (e.g. adjusted Incidence Rate Ratios [aIRRs] for inpatient admissions 0{middle dot}56, 95%CI 0{middle dot}30 to 0{middle dot}64) and 12 months (aIRR 0{middle dot}60, 95%CI 0{middle dot}44 to 0{middle dot}81). At 12 months, students showed a {pound}5 028 (95%CI -{pound}8 223 to -{pound}1 834) greater reduction in total costs per student compared with controls. This indicates that RCs offer an 8{middle dot}4:1 financial return on investment. Students also showed relative reductions in all-cause hospital bed days at six months (aIRR 0{middle dot}53, 95%CI 0{middle dot}35 to 0{middle dot}81) and 12 months (aIRR 0{middle dot}66, 95%CI 0{middle dot}46 to 0{middle dot}96), with a {pound}412 (95%CI -{pound}1 085 to -{pound}260) greater reduction in associated total costs at 12 months. Among students, reductions in Health of the Nation Outcome Scale (HoNOS) scores indicated consistent improvement in functioning over time. InterpretationMental health service users who enrol in a RC have reduced subsequent mental and all-cause healthcare use, and reduced service-related costs compared with matched service users not using a RC. Service user outcomes are also improved. FundingNational Institute for Health and Care Research. Research in contextO_ST_ABSEvidence before this studyC_ST_ABSSince the first one opened in England in 2009, Recovery Colleges (RCs) have spread globally. A 2025 review collating 2013-2024 evidence (64 papers) identified 11 studies investigating outcomes and four investigating service use. Quantitative evaluation of outcomes has used pre-post designs to investigate the impact of RCs on components of recovery, finding consistent evidence of benefit in relation to a number of outcomes including wellbeing, empowerment, hope, and social inclusion. Service use studies have indicated benefits from RC attendance, including increased employment and reduced hospital admissions and bed days, with preliminary evidence of associated cost savings. However, across all studies the evidence quality is low, with most outcome studies using small samples (mostly <100 students) and none using a separate control group. Consequently, change due to other factors such as measurement error or time cannot be discounted, so causation cannot be established. Added value of this studyThis is the largest study of its kind which utilises a methodologically rigorous approach to investigate the impact of RCs on service use, costs and outcomes. In 6 100 people, we identified a consistent positive impact for service user students, compared with optimally matched service user non-students, in relation to mental health service use at an index mental health provider (especially in-patient admissions) and wider all-cause hospital service use (especially bed days) at 12 months post-enrolment, resulting in relative cost savings for service users who are students compared with those who are not. Furthermore, we showed a relative beneficial impact for students on functioning consistently up to five years after RC enrolment. Implications of all the available evidenceThe evidence base for supporting RCs is significantly strengthened. Mental health service users who are students at RCs are likely to benefit, both in terms of clinical outcomes and reduced service use, compared to similar people not using the RC. Significant cost savings also arise, which we estimate as an 8{middle dot}4:1 financial return on investment. Our study evidence supports ongoing investment in RCs with significant return on investment, especially in England.
