Factors Associated with Length of Hospital Stay among HIV Positive and HIV Negative Patients with Tuberculosis in Brazil

Identify and analyze the factors associated to length of hospital stay among HIV positive and HIV negative patients with tuberculosis in Manaus city, state of Amazonas, Brazil, in 2010.Student test at a 5% significance level.Income from 1 to 3 minimum wages (P = 0.028), pulmonary tuberculosis form (P = 0.011), negative smear test or no information in this regard (P = 0.014), initial 6-month treatment scheme (P = 0.029), and adverse drug reactions (P = 0.021) were associated to prolonged hospital stay in HIV positive patients.We found out that although there were no significant differences in the length of hospital stay in HIV positive patients, all factors significantly associated to prolonged hospital stay occurred in this group of patients. This finding corroborates other studies indicating the severity of tuberculosis in HIV patients, which may also contribute to lengthen their hospital stay
