title: Determinants of once-only contact in a community-based psychiatric service.
abstract: BACKGROUND
  This study examined variables associated with patients who had a once-only contact with the out-patient department of a Community Mental Health Service (CMHS).
  
  
  METHODS
  Using the South-Verona Psychiatric Case Register (PCR), an 8-year cohort of patients who had a new episode of care with the out-patient department of the South Verona CMHS was followed up for 3 months after the first contact, to identify those patients who had no further contact with the service. Potential determinants of once-only contact were analysed.
  
  
  RESULTS
  A total of 2,446 new episodes of care met the inclusion criteria of the study. Of those, 734 (30%) were once-only contacts with the service. Compared to patients with more than one contact, patients who had a once-only contact were older, more likely to be male, had a lower socio-economic status and less severe psychiatric diagnosis. They were more likely to be referred by consultation/liaison or emergency room.
  
  
  CONCLUSIONS
  Multivariate analysis revealed that having a less severe psychiatric diagnosis was the most significant determinant of once-only contact with a CMHS. The results suggest that the behaviour of referring agents in selecting patients and preparing them for treatment merits further investigation.
