Patients with a psychiatric disorder in general practice: determinants of general practitioners' psychological diagnosis.
BACKGROUND
Although psychiatric disorders are highly prevalent in the community, many patients with a psychiatric morbidity remain unidentified as such in primary care.


OBJECTIVE
The aim of this study was to analyze which clinical and sociodemographic characteristics of patients with psychiatric morbidity are related to general practitioners' (GPs) diagnosis of mental illness.


METHODS
A 1-year naturalistic survey of primary care contacts of patients with a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) diagnosis of affective disorder, anxiety disorder or alcohol abuse was carried out.


RESULTS
Of the patients with a DSM-IV diagnosis, 10% did not visit their GP at all during 1 year, 40% visited their GP but were only diagnosed as having somatic diagnoses and 50% were given a psychological or social diagnosis at least once during 1 year. Affective disorders are more frequently diagnosed than anxiety disorders or alcohol abuse. The chances of psychological GP diagnosis increase with the number of GP contacts.


CONCLUSIONS
GPs appear to have few indications to help them distinguish patients with a psychiatric morbidity from others, as long as the patients themselves do not express more explicit clues to their condition. Public mental health education and a better public relations policy are badly needed.
