ABSTRACT

BACKGROUND: Mental health issues are prevalent among children and young people (CYP) with chronic conditions like epilepsy, yet few access evidence-based psychological therapies. Evidence from the Mental Health Intervention for Children with Epilepsy (MICE) trial supports the effectiveness of a personalised modular psychological intervention, but cost-effectiveness is unknown.

AIMS: To assess the cost-effectiveness of the MICE intervention compared with assessment-enhanced usual care at 12-months follow-up, taking a health and social care perspective.

METHOD: We conducted a within-trial economic evaluation. Outcomes were the Strengths and Difficulties Questionnaire (SDQ; primary) and quality-adjusted life years (QALYs; secondary) for CYP, caregivers, and CYP and caregivers combined. Sensitivity analyses examined missing data and intervention-costing assumptions.

RESULTS: Cost-effectiveness results for the SDQ indicated that MICE had a higher probability of being cost-effective compared with control at a willingness to pay ≥£368 per unit improvement. For QALYs, MICE had a lower probability of being cost-effective for CYP compared with control (35 to 42%) across the £20 000-£30 000 per QALY threshold range. However, at the upper threshold this finding was reversed in sensitivity analyses with missing data imputed (45 to 58%) and with MICE costed at 75%, assuming the intervention partly substituted standard services (46 to 55%). Furthermore, MICE had a higher probability of being cost-effective for caregiver QALYs (52 to 63%) and combined CYP and caregiver QALYs (62 to 75%).

CONCLUSIONS: MICE appears to be cost-effective compared with assessment-enhanced usual care when considering QALYs for CYP and caregivers combined, though uncertainty exists across willingness-to-pay thresholds.
