Abstract

Objective Increasing numbers of young people attending university has raised concerns about the capacity of student mental health services to support them. We conducted a randomised controlled trial (RCT) to explore whether provision of an 8 week mindfulness course adapted for university students (Mindfulness Skills for Students - MSS), compared with university mental health support as usual (SAU), reduced psychological distress during the examination period.

Here, we conduct an economic evaluation of MSS+SAU compared with SAU. Design and setting Economic evaluation conducted alongside a pragmatic, parallel, single-blinded RCT comparing provision of MSS+SAU to SAU.

Participants 616 university students randomised. Primary and secondary outcome measures The primary economic evaluation assessed the cost per quality-adjusted life year (QALY) gained from the perspective of the university counselling service.

Costs relate to staff time required to deliver counselling service offerings. QALYs were derived from the Clinical Outcomes in Routine Evaluation Dimension 6 Dimension (CORE-6D) preference based tool, which uses responses to six items of the Clinical Outcomes in Routine Evaluation Outcome Measure (CORE-OM; primary clinical outcome measure).

Primary follow-up duration was 5 and 7 months for the two recruitment cohorts. Results It was estimated to cost pounds1584 (2022 prices) to deliver an MSS course to 30 students, pounds52.82 per student.

Both costs (adjusted mean difference: pounds48, 95% CI pounds40-pounds56) and QALYs (adjusted mean difference: 0.014, 95% CI 0.008 to 0.021) were significantly higher in the MSS arm compared with SAU. The incremental cost-effectiveness ratio (ICER) was pounds3355, with a very high (99.99%) probability of being cost-effective at a willingness-to-pay threshold of pounds20 000 per QALY.

Conclusions MSS leads to significantly improved outcomes at a moderate additional cost. The ICER of pounds3355 per QALY suggests that MSS is cost-effective when compared with the UK's National Institute for Health and Care Excellence thresholds of pounds20 000 per QALY.
