The most common psychiatric diagnoses among inpatients were schizophrenia (55.8%), bipolar disorder (23.3%) and major depressive disorder (7.2%). The most common psychiatric diagnoses among outpatients were major depressive disorder (29.3%), schizophrenia (28.9%), generalized anxiety disorder (15.6%) and bipolar disorder (11.5%). Primary psychotic disorders and secondary psychiatric disorders were significantly more frequent among men whereas primary bipolar disorders and depressive disorders were significantly more frequent among women in both inpatient and outpatient settings. Psychotic and bipolar disorders were significantly more frequent among younger patients whereas depressive disorders were significantly more frequent among older patients; anxiety disorders were of similar frequency in all age groups.
