The determinants and effect of shared care on patient outcomes and psychiatric admissions

factors associated with receipt of different levels of shared care, and the effect of shared care on patient outcomes. Method A total of 349 patients with severe mental illness were selected from general practice lists. Patient functioning was assessed using standardised questionnaires, and GPs completed a questionnaire about patients’ shared care arrangements at baseline (response-rate 79 %). Patients were followed up at 12 months. Results Receipt of high shared care was associated with greater patient satisfaction with services and social functioning at baseline (p<0.005). Patients receiving high shared care showed greater improvements in SF-12 mental health scores at follow-up compared to low shared care groups (p=0.02). This effect was abolished after adjustment for age, sex and psychiatric diagnosis. Conclusion Receipt of high shared care was not associated with demographic or clinical characteristics. High shared care had limited value for patients in terms of improved clinical, social or general health functioning over one year.
