Impact of the 1970 Reforms to Cuba's National Tuberculosis Control Program.

INTRODUCTION To reach the goal of eliminating tuberculosis as a public health problem in Cuba, the epidemiological evolution of the disease and of strategies designed to prevent and manage it to date must be well understood. In this context, in 1970, changes were introduced in Cuba's National Tuberculosis Control Program. OBJECTIVE Review background and evolution of Cuba's strategy for tuberculosis control, the changes implemented in the 1970 revision of the Program, and their impact on the subsequent evolution of the disease in Cuba. METHODS Published articles on the history of tuberculosis control in Cuba were reviewed, along with archival documents and medical records. Documents concerning the situation of pulmonary tuberculosis in Cuba, including measures adopted to address the disease and its extent, were selected for study, with an emphasis on the period of the Program. Interviews with key informants were conducted. RESULTS Cuba's fight against tuberculosis began in Santiago de Cuba, with the creation of a local Anti-Tuberculosis League in 1890. Strategic changes introduced by Cuba's public health sector, stressing health promotion and disease prevention, led to the 1959 creation of the Tuberculosis Department, which implemented Cuba's first National Tuberculosis Control Program in 1963. This Program was completely reorganized in 1970. The National Tuberculosis Control Program (1963) covered a network of 27 tuberculosis dispensaries, 8 sanatoriums and 24 bacteriology laboratories. Diagnosis was based on radiographic imaging criteria. Incidence was 52.6/100,000 in 1964 and reached 31.2 in 1970. The Program was updated in 1970 to include two major changes: the requirement for bacteriological confirmation of diagnosis and directly-observed outpatient treatment fully integrated into health services. By 1971, incidence was down to 17.8/100,000, and further reduced to 11.6 in 1979. The decrease is interpreted as the result of the greater specificity of microbiologic diagnosis. Tuberculosis control continued to make progress, reaching an incidence rate of 6.1/100,000 in 2012 and mortality rate of 0.3/100,000 in 2013. CONCLUSIONS Changes introduced in the National Tuberculosis Control Program in 1970 led to the successful results achieved in later decades, reducing tuberculosis incidence and mortality. These results also allowed health authorities to propose elimination of the disease in Cuba as a current objective.
