Psychotic symptoms in primary care.

BACKGROUND: Psychotic symptoms include a variety of disturbances in perception, reality testing, speech, and behavior. We examine the prevalence, distribution, treatment, and functional impairment associated with psychotic symptoms in primary care patients. METHODS: Data are drawn from a recent study of adult primary care patients (N = 1001) in a large, urban, prepaid group practice. At the medical visit, patients completed a questionnaire that probed demographic characteristics, health status, and mental health care utilization. Following the visit, patients received a telephone-administered, structured psychiatric interview that included 11 psychotic symptoms. Medication prescription data were also available. Comparisons are presented of patients with and without psychotic symptoms. RESULTS: Thirty-seven (3.7%) patients reported one or more psychotic symptoms, most commonly a belief that others were spying on or following them (n = 16). As compared with patients without psychotic symptoms, a larger proportion of the patients with psychotic symptoms reported mental health-related work loss (54.1% vs 17.9%, P < .0001), suicidal ideation (21.6% vs 2.6%, P < .0001), major depressive disorder (32.4% vs 6.3%, P < .0001), bipolar disorder (29.7% vs 1.2%, P < .0001), and several other mental disorders. An antipsychotic medication had been prescribed during the previous 17 to 20 months for only two (5.4%) of the patients with psychotic symptoms. CONCLUSIONS: Psychotic symptoms were relatively common (3.7%) in this practice and were strongly associated with functional impairment and affective, anxiety, or substance use disorders. Primary care physicians are encouraged to examine patients with these mental disorders for the presence of psychotic symptoms.
