Intensive versus standard case management for severe psychotic illness: a randomised trial. UK 700 Group.

BACKGROUND

Case management has increasingly been the recommended approach to care for severely mentally ill patients since the number of psychiatric beds has decreased. Despite equivocal results, in the UK and Europe, this approach is becoming accepted policy. We assessed the effect of smaller case loads.

METHODS

We randomly assigned 708 psychotic patients in four centres standard case management (355 patients, case load 30-35 per case manager) or intensive case management (353 patients, case load 10-15 per case manager). We measured clinical symptoms and social functioning at baseline, 1 year, and 2 years. The impact of treatment on hospital use was assessed at 2 years by subgroup analyses for Afro-Caribbean and for severely socially disabled patients. Analysis was by intention to treat.

FINDINGS

There was no significant decline in overall hospital use among intensive-case-management patients (mean 73.5 vs 73.1 days in those who received standard care [SD 0.4, 95% CI -17.4 to 18.1]), nor were there any significant gains in clinical or social functioning. There was no evidence of differential effect in Afro-Caribbean patients or the most socially disabled patients.

INTERPRETATION

In well-coordinated mental-health services, a decline in case load alone does not improve outcome for these patients. Mental-health planners may need to pay more attention to the content of treatment rather than changes in service organisation.
