Abstract: Following a retrospective review of tuberculosis cases reported from Ottawa County, Oklahoma, from 1969 through 1973, a selective tuberculosis screening project was implemented. Screening of a "target group" of the population, 519 former miners, is greater than or equal to 50 years of age, resulted in the discovery of abnormal chest X-rays in 182; (103 with silicosis, 36 with silicotuberculosis, 12 with inactive tuberculosis, and 31 with other abnormalities). Eighty-five of these persons had positive tuberculin skin tests. Preventive therapy was recommended for 50, and 36 completed the prescribed course of treatment. Eight new bacteriologically confirmed cases of tuberculosis were found and treated. A large number of persons (1,904) residing in the same area who were not part of the target group were also screened for tuberculosis. This group contained a large number of positive tuberculin reactors but very few were candidates for isoniazid preventive therapy. Thirteen persons in this group had abnormal chest X-rays consistent with inactive tuberculosis but 12 had been identified and given preventive therapy before the project began. These data suggest that selective approaches to screening for tuberculosis in a community which are based on an in-depth retrospective review of the tuberculosis case register can be highly successful.
