MARTINEZ-GUTIERREZ, María Soledad et al. Pilot study: tobacco-attributable direct costs in two hospitais in Santiago, Chile. Rev. méd. Chile [online]. 2008, vol.136, n.10, pp. 1281-1287. ISSN 0034-9887. http://dx.doi.org/10.4067/S0034-98872008001000007.
Background: Tobaceo is the fourth cause of the global burden of disease, accounting for 79.9 million loss of disability-adjusted Ufe years (DALYs) in 2001. In 2002, tobacco-attributable mortality in Chile represented 17% of total mortality. Aim: To estimate the direct cost of tobaceo in Ischemic Heart Disease, Chronic Obstructive Pulmonary Disease and Lung Cáncer, explore patients' disposition to answer a health related expenses questionnaire, valídate the instruments used and determine an adequate sample size for an upcoming study. Material and methods: Socio-demographic and health care related variables were investigated among patients attending two publie hospitais for ischemic heart disease, chronic obstructive pulmonary disease and lung cancer, in a cross-sectional study. Costs were estimated using the national publie health insurance price list and market pnces. Tobacco-attributable fraction was then applied to calcúlate the tobacco-attributable cost ofeach disease. Results: The instruments used were validated. The group of lung cáncer patients was smaller due to increased mortality prior to interview. Lung cancer generated the largest total and attríbutable direct costs. The costs in patients with ischemic heart disease were significantly lower Conclusions: There were some difficulties in the application of the questionnaire to register medication use. The sample size needed in a larger study was calculated for each of the three diseases. We recommend that a definitive study addresses tobacco-attributable direct costs related to chronic obstructive pulmonary disease.
