Objective: To evaluate the level of access to health care clinics of a population of patients hospitalized for tuberculosis (TB) at two hospitals in the city of São Paulo, Brazil, comparing them with a population of TB patients under outpatient treatment only. Methods: We compiled sociodemographic, clinical and epidemiological data related to patients hospitalized for TB at two hospitals in the city of São Paulo, Brazil, between January and December of 2007, using a structured questionnaire. We also identified the outpatient clinics to which the patients were referred at discharge. The same variables were evaluated for TB outpatients during the same period, using a database. Results: The study sample consisted of 474 patients (166 inpatients and 308 outpatients: mean age, 41.0 and 39.1 years, respectively). The univariate analysis showed positive associations between hospitalization due to TB and the following variables: 30-39 year age bracket (OR = 2.17); 50-59 year age bracket (OR = 2.17); combination of pulmonary and extrapulmonary forms of TB (OR = 5.31); TB re-treatment (OR = 2.66); seeking treatment at other health care facilities prior to the diagnosis of TB (OR = 2.05); symptom duration of more than 12 weeks (OR = 2.23); and TB diagnosed at hospitals or in emergency rooms (OR = 4.68). The proportion of inpatients who resided in the same regional health district area as that in which the respective hospital was located was 77.6% and 36.8%. The proportion of discharged patients who were referred to outpatient clinics in the same areas was 67.1% and 39.7%, respectively. Conclusions: Patients hospitalized for TB should be monitored from discharge until their admission to the outpatient clinic.

Objective: To compare inpatient and outpatient treatment of tuberculosis, in terms of outcomes, in the city of São Paulo, Brazil, as well to determine which variables are most frequently associated with hospitalization. Methods: A prospective, longitudinal study carried out between January and December of 2007, at two large hospitals and at outpatient clinics, in two regions of the city of São Paulo. For inpatients, data were collected with a structured questionnaire. Additional data were obtained from the São Paulo State Department of Health Tuberculosis Database. Results: Of the 474 patients included in the study, 166 were inpatients, and 308 were outpatients. The multivariate analysis showed that hospitalization for tuberculosis was associated with hospital/emergency room diagnosis of tuberculosis (OR = 55.42), with HIV co-infection (OR = 18.57), with retreatment (OR = 18.51), and with having previously sought treatment at another health care facility (OR = 12.32). For the inpatient and outpatient groups, the overall cure rates were 41.6% and 78.3%, respectively, compared with 30.4% and 58.5% for those who were co-infected with HIV, whereas the overall mortality rates were 29.5% and 2.6%, respectively, compared with 45.7% and 9.8% for those who were co-infected with HIV. Conclusions: Among inpatients, tuberculosis appears to be more severe and more difficult to diagnose, resulting in lower cure rates and higher mortality rates, than among outpatients. In addition, tuberculosis patients co-infected with HIV have less favorable outcomes.
