Abstract
In 1964, 219,085 persons were examined during a tuberculosis survey in Vancouver: 115 new cases of tuberculosis and 929 cases of significant non-tuberculous lung disease were found. In a 4 mo. follow-up of the non-tuberculous cases it was found that of the 742 patients who named a physican when examined 26.6% did not contact him. Of those who did contact the physician, the follow-up was considered "poor" in only 30 patients (2.1%). Seventeen patients died in the four-month interval and 81 who could not be located after the initial survey were considered "lost". Rates were determined for 37 diagnoses/1000 patients screened. The most common diagnosis was localized pulmonary fibrosis (1.69/1000). Carcinoma was found in 0.30/1000 and solitary lung density in 0.17/1000 populations screened.
