Conditions That Do Not Reach the Threshold for Mental Disorder in Spanish Psychiatric Outpatients: Prevalence, Treatment and Management

Background: In recent years there has been controversy around the treatment demands of people who, without meeting diagnostic criteria for a mental disorder, have certain symptoms and are referred to mental health professionals.Aims: To determine the prevalence of individuals assessed by mental health service, referred from primary care, who do not meet the diagnosis criteria of mental disorders according to ICD-10. To analyze the medical treatment given to these individuals, measured by the indication for discharge or follow-up and by the pharmacological intervention decided in the first interview, as well as the associated variables.Method: Design: descriptive study. Scope: urban area. Population: all patients referred to the Salamanca mental health service during a year, without any exclusion (n = 1,187). Variables: sociodemographics; clinical and health service utilization gathered through clinical interview, GHQ-28, SCL-90-R and an expectations scale.Results: Of the 1,004 patients who attended interview, 24.4% (CI 95%: 21.6-27.0) did not present any diagnosable mental disorder (Z codes); they constitute the body of this study. 50.8% of these were referred from primary care with a psychotropic drug treatment already prescribed. Any drug intervention (addition, suspension or modification) was performed in 37.2% of the cases by the mental health service. Regardless of the treatment indicated, 52% were discharged after the first interview.Conclusions: The prevalence of patients who failed to reach diagnostic criteria for a mental disorder in this health service is similar to other studies, in spite of the filter provided by primary care. Many individuals without a diagnosable mental disorder received treatment both in primary care and in the mental health service.
