Characteristics of patients with hypnotic-related psychiatric disorders in the nationwide mental hospital survey

Abstract

We investigated the characteristics of patients with hypnotic-related psychiatric disorders. Subjects were 90 patients reported in the nationwide Mental Hospital Survey in 1998, who were divided into three groups according to their history of substances use. Group A (patients without history of any illicit substance use) was estimated to be the most common and core group with iatrogenic characteristics. Hypnotic use in Group B (patients with history of any illicit substance use) was recognized as one of behavioral disorders in the psychosocial context. Patients in Group C (patients with multiple-substance use and without history of any illicit substance use) showed the most serious disorders in the context of addiction. More specified treatment programs would be required considering patients' characteristics.
