title: [Evidence-based tuberculosis control: a public health approach].
abstract: Evidence-based medicine is the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients. One of the differential traits of the practice of public health when compared to clinical medicine is that it does not concentrate in individual patients, but rather in the health problems of the population in a given time. In public health interventions, besides the importance of efficacy, aspects related to the process of implementation become also crucial. This paper develops some principles for evidence-based public health, which are then applied to a given problem: tuberculosis control in our context. Tuberculosis control poses challenges which go beyond clinical practice, and require a collective organized effort. This is precisely what makes it a public health issue and not only a clinical problem, as it requires not only health care dimensions but also public health dimensions, which require policies that are feasible, have high efficacy, and a moderate cost. To illustrate the problem and the results of public health policies, available data and indicators are used, with special reference to the authors experience in the program for the prevention and control of tuberculosis in Barcelona (Catalonia, Spain).
