Demographic and clinical profiles of patients who make multiple visits to psychiatric emergency services.
OBJECTIVE
The study identified clinical and sociodemographic characteristics of patients making multiple visits to a psychiatric emergency service.


METHODS
Information was obtained for patients visiting a hospital psychiatric emergency service in Montreal from 1985 to 2000. Profiles were determined for four groups: one visit, two visits, three to ten visits, and 11 or more visits. To determine whether the profile for those with 11 or more visits was generalizable, data for patients visiting the main site and three other such services from 2002 to 2004 were similarly analyzed.


RESULTS
At the main study site (1985 to 2000), patients with single visits accounted for 36% of the 29,569 visits. The 292 patients with 11 or more visits accounted for almost 21% of total visits. Timing of the visit-time of day and day of the week-did not differentiate between groups. However, time itself was important in identifying patients with 11 or more visits: use of 30-month observation periods resulted in identification of only 8% of this group. Patients with 11 or more visits were more likely to be diagnosed as having schizophrenia and as having a comorbid diagnosis and were generally younger at the index visit and more economically impaired than those in the other groups. Overall, and at two of the three other sites, schizophrenia was overrepresented in the highest user group.


CONCLUSIONS
Most visits to the psychiatric emergency service were made by frequent users who had distinctive profiles, which are potentially useful for developing clinical strategies to reduce the impact of this patient group on this service.
