THE study of the fate of persons who have received treatment for pulmonary tuberculosis in sanatoria is of considerable importance to the clinician and also to the epidemiologist. Definite knowledge of what happens following discharge from a sanatorium is necessary not only to evaluate the results of sanatorium treatment and to advance a prognosis, but such knowledge can also be of value as an index in comparing the characteristics of the disease in different areas. Attempts to obtain exact knowledge of events subsequent to discharge by relying upon the patient's co6peration either in reporting at specified intervals or in replying to questionnaires, are prone to yield results which contain bias because of the inability of fatal cases to report and a tendency for those who have improved to cooperate more readily. Only by a systematic follow-up through personal canvas can the percentage lost from observation be lowered and bias reduced to a minimum. |
