Effectiveness and costs of acute day hospital treatment as compared with conventional in-patient care: a randomised controlled trial

BACKGROUND: Data on effectiveness of acute day hospital treatment for psychiatric illness are inconsistent. AIMS: To establish the effectiveness and costs of care in a day hospital providing acute treatment exclusively. METHOD: In a randomised controlled trial, 206 voluntarily admitted patients were allocated to either day hospital treatment or conventional wards. Psychopathology, treatment satisfaction and subjective quality of life at discharge, 3 months and 12 months after discharge, readmissions to acute psychiatric treatment within 3 and 12 months, and costs in the index treatment period were taken as outcome criteria. RESULTS: Day hospital patients showed significantly more favourable changes in psychopathology at discharge but not at follow-up. They also reported higher treatment satisfaction at discharge and after 3 months, but not after 12 months. There were no significant differences in subjective quality of life or in readmissions during follow-up. Mean total support costs were higher for the day hospital group. CONCLUSIONS: Day hospital treatment for voluntary psychiatric patients in an inner-city area appears more effective in terms of reducing psychopathology in the shortterm and generates greater patient satisfaction than conventional in-patient care, but may be more costly.
