OBJECTIVE: To determine the mortality rate and risk factors for in-hospital death among hospitalised human immunodeficiency virus (HIV) negative tuberculosis (TB) patients in poor urban areas in the Philippines. DESIGN: A cross-sectional study was conducted at a national infectious disease hospital in Manila City. The target population was patients aged ≥13 years with all forms of HIV-negative TB admitted from October to December 2009. Demographic and clinical information was collected from medical charts, and risk of in-hospital death was measured. RESULTS: Of 407 HIV-negative TB patients, four were excluded due to missing records, and 403 were included in the analysis. The majority were poor urban residents (90%), and 66% were males. Overall, 37.5% of hospitalised patients died in the hospital (151/403), 30% of whom died before the third day of hospitalisation. Risk factor analysis demonstrated that complications of bacterial pneumonia had the greatest effect on in-hospital death (aOR 4.53, 95%CI 2.65–7.72), followed by anorexia (aOR 3.01, 95%CI 1.55–5.84), anaemia (haemoglobin <10 g/dl, aOR 2.35, 95%CI 1.34–4.13) and older age (aged ≥50 years, aOR 1.85, 95%CI 1.08–3.17). The presence of haemoptysis (aOR 0.44, 95%CI 0.25–0.80) was associated with improved survival. CONCLUSION: Mortality among hospitalised HIV-negative TB patients was extremely high in poor urban areas in the Philippines.
