Purpose And MethodsThere has been a recent increase in the number of non-profit facilities that provide shelter for the homeless. These social service facilities aim to assist the social rehabilitation of homeless persons. The Public Health Center of Chiba City screened 1,054 residents of these homeless shelters between November 2002 and August 2004 and found 17 individuals (1.6%) with active pulmonary tuberculosis. We clinically reviewed these cases.ResultsAll 17 individuals were male, and their ages ranged from 44 to 70 years (mean 54.9 years). Four cases were smear positive and three cases were smear negative but culture positive by sputum examination for acid-fast bacilli. Nine cases had cavitary lesions on chest X-ray. There were three cases complicated with hepatitis C, two cases with diabetes mellitus and two cases with past history of gastrectomy. Of the 17 individuals, 13 were treated as inpatients, and four as outpatients. The mean hospitalization duration was 146.7 days excluding two patients who were discharged by themselves. Of the 11 inpatients, four remained hospitalized until the completion of treatment. Final outcome of the treatment was the following; 12 patients were cured, while five patients dropped out or discontinued treatment.ConclusionThe screening performed by the Public Health Center of Chiba City revealed a very high prevalence of tuberculosis among shelter residents. Thus, in the future, public health centers and medical institutions must work in collaboration to actively screen and provide treatment for residents of homeless shelters. This study also revealed that in spite of recommended hospitalization or long-term treatment, patients often self-discharged or discontinued regular outpatient treatment. Health centers and other public agencies must therefore work in close cooperation to help the homeless to continue hospitalization and subsequent medication and treatment even after their discharge from hospital.
