Sociodemographic and clinical profiles of homeless mentally ill admitted in mental health institute of South India: 'Know the Unknown' project.

OBJECTIVES: A significant number of homeless mentally ill (HMI) patients without any personal, family or other identification details represent a unique problem in the psychiatric services of developing countries like India in the context of legal, humanitarian and treatment issues. These patients pose challenge to the mental health professional in diagnosis and management.

AIMS: To study the sociodemographic and clinical profiles of HMI patients admitted under psychiatry.

METHODS: We performed a retrospective chart review of 'HMI' patients from 1 January 2002 to 31 December 2015, who were admitted to the Department of Psychiatry at National Institute of Mental Health and Neurosciences (NIMHANS), Bangalore, India. Sociodemographic and clinical profiles of the patients were analyzed by descriptive statistics.

RESULTS: Mean age of the sample was 34.6 years (±12.21 years), 42 (53.8%) were females, 74 (94.9%) were registered as Medico Legal Case and 53 (80.8%) were admitted under reception order issued by a magistrate. HMI patients brought by police were 32 (41.0%), by the public were 32 (41.0%) and 14 (18.0%) by nongovernmental organization /ambulance/social worker. In total, 51 (65.4%) of them had schizophrenia and other psychotic disorders, 24 (30.8%) had mental retardation and 23 (29.5%) had a comorbid substance use disorder. The mean Clinical Global Impression severity at admission was 5.07 (±1.7), and the mean duration of inpatient care was 15 weeks. Anemia and malnutrition were found in 34 (43.6%) and 25 (32.1%) patients, respectively.

CONCLUSION: This study shows that schizophrenia, comorbid mental retardation and substance use disorder are common causes of admission of HMI patients in psychiatry. It is an emerging problem, which needs urgent interventions, and there is a need for an efficient system, guidelines and collaboration with government and nongovernmental agencies.
