Cost of post-deployment screening for mental illness in the UK military: findings from a cluster randomised controlled trial

Abstract

Background

Little is known about the economic impact of military mental health screening.

Aims

To investigate (a) whether post-deployment screening of military personnel affects use and cost of services and (b) the impact of psychiatric morbidity on costs.

Methods

Participants were recruited from UK Royal Marine and Army platoons and randomised to an intervention group (which received tailored advice predicated upon mental health status) or a control group (which received general advice following assessment of mental health status). The intervention costs were calculated while service use and associated costs were assessed at 12-month follow-up.

Results

Data were available for 6323 participants. Mean screening cost was £34. Service costs were slightly higher in the control group compared to the intervention group (£1197 vs. £1147) which was not statistically significant (bootstrapped 95%CI, −£363 to £434. In both groups, screening and control, costs were significantly higher for those who screened positive for mental health problems.

Conclusions

Costs were not affected by screening. In countries that have already implemented post-deployment screening, the political cost of disinvestment needs careful consideration. Those who develop psychiatric morbidity have substantially higher care costs than those who do not.
