[Management of mycobacteriosis in general hospital without isolation ward for tuberculosis patients. 4. Actual status of the management of tuberculosis patients in a university hospital without isolation wards for infectious diseases].

We retrospectively evaluated clinical findings and the actual status of management of 69 tuberculosis patients admitted to the Fujita Health University Hospital, a hospital without isolation wards for infectious diseases, between 1991 and 1994. Forty-nine patients were smear-positive and 22 patients were smear-negative and culture-positive. Twenty-five cases (36.2%) were classified as type II (cavitary) and 29 cases (42.0%) as type III (non-cavitary) according to the GAKKAI classification of findings on chest X-ray films for pulmonary tuberculosis. Physicians in charge did not diagnose twenty-four patients (34.8%) as tuberculosis on admission. Physicians in charge tended not to suspect smear-negative patients of tuberculosis. Most of the patients with cavities on their chest X-ray films were strongly suspected of tuberculosis on admission, but in some of them, tuberculosis was not considered at all. Smear-positive patients with strongly suspected tuberculosis were diagnosed with the disease within three hospital days, while it took about three weeks in patients who were not considered as tuberculosis on admission to be diagnosed as tuberculosis. In the case of smear-negative patients, it took about one month and two months respectively to diagnose the case as tuberculosis. About half (51.1%) of the smear-positive patients were admitted and treated in single-bed rooms while 44.7% were attended in multiple-bed rooms for 11 days before they were transferred to single-bed rooms. When acid-fast bacilli were detected, 57.4% of the smear-positive patients were transferred to hospitals with isolation wards for infectious diseases, while the remaining smear-positive patients were treated in single-bed rooms at the university hospital. About one-third (31.7%) of the smear-negative patients had already left the hospital when specimens were found to be culture positive for tubercle bacilli. In conclusion, it is utmost important for physicians to suspect to tuberculosis for the early diagnosis of the disease.
