IntroductionIn psychiatric practice, some mentally ill patients spend their life in continuous or prolonged hospitalization; that is, as long stay patients. 1,2 This is due among other reasons to severe mental illness with poor symptom control, substance dependence, homelessness and abandonment by the patients' relatives. 3,4 Furthermore, in developing countries such as Nigeria, the situation is slightly different. The issue of long-stay patients is intertwined with the historical development of orthodox psychiatric care. In the early 20th century, asylums were established in selected towns and cities in the country by the then colonial powers. These were to serve as places of confinement or long-stay for psychiatrically ill offenders. 5,6 Over the years, these asylums were converted to fully-fledged psychiatric hospitals; with most of the long-stay offender inmates remaining in these facilities till date. 6 Another major source of long-stay patients is from the population of vagrant, psychotic individuals in the country. From time to time, the Nigerian print media focuses on this situation. 7,8 Some of these vagrant patients have over the years found their way to hospital, with a prolonged stay, by being brought to the centre by government health officials or most times by concerned members of the public. 9 Finally, in the study centre, the additional source of long-stay patients include some abandoned mentally ill returnee Nigerian soldiers from both the Second World War as well as the Nigerian civil war of 1967-1970. However, the cost of prolonged hospitalization care for these patients is borne by the hospital management. In the face of recently introduced government health reform and the dwindling number of available beds for acutely ill patients, a cross sectional study was carried out on long-stay patients at the 100 years old psychiatric hospital Yaba, Lagos, Nigeria with a view to discharging most of them. Method: Necessary consent was obtained from the Hospital Research and Ethical Committee. All the long-stay patients were evaluated with a specially designed proforma to elicit socio-demographic, clinical and long-stay variables. Further more, each of them had clinical assessment to make diagnosis in accordance with ICD -10 and finally, the subjects were also assessed with the Brief Psychiatric Rating Scale (BPRS). Results: Fifty-one (51) subjects; that is, occupying 10.7% of the hospital functional beds fulfilled the criteria of long-stay. They included 36 (70.6%) males and 15(24.4%) females. The mean age was 47.3±16.5 years with age range of 18-92 years. The average length of stay was 11.4±15.0 years and range of 0.5 to 57 years; with significant gender difference (males higher than females) (t =3.51, p<0.02). The vast majority of the subjects were diagnosed with schizophrenia (84.3%), followed by mental retardation with seizure disorder (5.9%). One-third (33.3%) of the subjects had co-morbid physical pathologies most especially epilepsies, hypertension, Koch's disease, HIV/AIDS. Despite being on hig...
