ABSTRACT This study examined characteristics of frequent visitors to a psychiatric emergency service in a French public teaching hospital over six years. Diagnostic variability of psychotic disorders was documented.
A retrospective review of the service's administrative and medical databases identified 1,285 patients with more than one visit during the period who were given at least one diagnosis of a psychotic disorder. A total of 317 patients with six or more visits (frequent visitors) were compared with 968 patients with between two and five visits (occasional visitors).
Frequent visitors were significantly more likely to be single and homeless and to have diagnostic variability, substance use disorders, and personality disorders. A total of 177 patients experienced diagnostic variability, which was found mainly in three diagnostic categories: schizophrenia, schizoaffective disorder, and bipolar disorder with psychotic features.
Future studies should further examine the link between increased use of emergency services and diagnostic variability.

    ABSTRACT: The aim of this study was to describe the characteristics of children and adolescents admitted to the psychiatric emergency department (ED) of a French public teaching hospital over a six-year study period (2001-2006). Data for all episodes of care in the psychiatric ED from January 1, 2001, to December 31, 2006, delivered to adolescents aged less than 18 years were retrospectively analyzed. During the six-year study period, 335 episodes of care in the psychiatric ED were experienced by 264 different adolescents. They accounted for 2.0% of the 16,754 care episodes of the ED; 164 patients (62.1) were female and the average age was 16.5 (SD = 1.6). The neurotic, stress-related, and somatoform disorders were the most frequent (25.4%) and concerned mainly anxiety disorders (15.2%). The frequency of the absence of psychiatric diagnosis (22.7%) was high. A total of 48 children and adolescents (18.2%) benefited from more than one episode of care. Several factors were associated to a higher number of visits to the ED: substance use, schizophrenia, disorders of adult personality and behaviour, disorders occurring in childhood and adolescence, and dual diagnosis. In conclusion, mental health disorders in children and adolescents are a serious problem associated with several potentially modifiable factors.

    ABSTRACT: This study aimed to develop a self-administered, multidimensional, poverty-related quality of life (PQoL) questionnaire for individuals seeking care in emergency departments (EDs): the PQoL-17. The development of the PQoL was undertaken in three steps: item generation, item reduction, and validation. The content of the PQoL was derived from 80 interviews with patients seeking care in EDs. Using item response and classical test theories, item reduction was performed in 3 EDs on 300 patients and validation was completed in 10 EDs on 619 patients. The PQoL contains 17 items describing seven dimensions (self-esteem/vitality, psychological well-being, relationships with family, relationships with friends, autonomy, physical well-being/access to care, and future perception). The seven-factor structure accounted for 75.1% of the total variance. This model showed a good fit (indices from the LISREL model: root mean square error of approximation, 0.055; comparative fit index, 0.97; general fit index, 0.96; standardized root mean square residual, 0.058). Each item achieved the 0.40 standard for item internal consistency, and Cronbach α coefficients were >0.70. Significant associations with socioeconomic and clinical indicators showed good discriminant and external validity. Infit statistics ranged from 0.82 to 1.16. The PQoL-17 presents satisfactory psychometric properties and can be completed quickly, thereby fulfilling the goal of brevity sought in EDs.

    ABSTRACT: Substance misuse is frequently encountered in the psychiatric emergency service (PES) and may take many forms, ranging from formal DSM-IV diagnoses to less obvious entities such as hazardous consumption. Detecting such patients using traditional screening instruments has proved problematic. We therefore undertook this study to more fully characterize substance misuse in the PES and to determine whether certain variables might help better screen these patients. We used a prospectively acquired database of over 18,000 visits made to four PESs during a 2-year period in the province of Quebec, Canada. One of the variables acquired was a subjective rating by the nursing staff as to whether substance misuse was a contributing factor to the visit (graded as direct, indirect, or not at all). Substance misuse accounted for 21% of all diagnoses and alcohol was the most frequent substance used. Patients were divided into those with primary (PSM), comorbid (CSM) or no substance misuse (NSM). Depressive disorders were the most frequent primary diagnoses in CSM, whereas personality and substance misuse disorders were frequent secondary diagnoses in PSM. Although many variables significantly differentiated the three groups, few were sufficiently detailed to be used as potential screening tools. Those situations that did have sufficient details included those with a previous history of substance misuse, substance misuse within 48 hours of the visit, and visits graded by the nursing staff as being directly and/or indirectly related to substance misuse. Variables related to substance misuse itself were the primary predictors of PSM and, less significantly, CSM. The nursing staff rating, although promising, was obtained in less than 30% of all visits, rendering its practical use difficult to assess.
