The primary care physician (PCP) plays an important role in the outpatient care of psychotic patients, particularly in the early detection of these disorders. Through the PCP's status as a trusted individual who knows the patient and his/her family, his/her opinion and attitude influence treatment acceptance and, consequently, the prognosis. By ensuring the continuity of care, in collaboration with a psychiatrist, the PCP helps prevent relapse and the evolution towards chronicity and long-term handicaps. A high incidence of cardiopulmonary disease and concomitant substance abuse in the population of chronic psychotic patients, as well as the monitoring of potential somatic side effects of psychotropic medication, require regular somatic follow-up by the PCP.
