Abstract
BACKGROUND: Pulmonary tuberculosis with acute respiratory failure is fatal and is a burden in the intensive care units and leads to mortality. This retrospective study identifies the factors influencing the development of pulmonary tuberculosis requiring mechanical ventilation (TBMV) and mortality in the hospitalized patients with pulmonary tuberculosis. METHODS: The medical records of hospitalized adult patients with pulmonary tuberculosis were retrospectively reviewed. Demographic data, clinical presentations, radiographic findings, biochemical tests, and clinical outcomes were collected. Data were compared by Student's t-test and Chi-square test between groups. Select variables that were statistically significant with P values <0.1 were introduced into a forward, stepwise, logistic regression model. Odds ratios (ORs) and their 95% confidence intervals (CIs) identified the independent influencing factors in the development of TBMV and mortality. RESULTS: Of 268 enrolled patients, 185 (69.0%) were male. The patients were equally divided between the TBMV and non-TBMV groups. The shorter duration of illness (OR, 0.99; 95% CI, 0.98-0.99), underlying disease of AIDS (OR, 14.55; 95% CI, 1.71-123.91), presentation of fever (OR, 2.11; 95% CI, 1.20-3.71) and dyspnea (OR, 3.51; 95% CI, 2.02-6.11), large amount of acid fast bacilli on sputum smear (OR, 3.76; 95% CI, 1.90-7.47), lower serum albumin level (OR, 0.39; 95% CI, 0.26-0.59), and delayed initiation of anti-tuberculosis agents (OR, 1.06; 95% CI, 1.00-1.12) were independent factors to develop TBMV. Male gender (OR, 2.16; 95% CI, 1.01-4.61), consolidation pattern on chest X-ray (OR, 2.41; 95% CI, 1.17-4.98), and lower serum albumin (OR, 0.39; 95% CI, 0.21-0.71) were correlated to mortality. CONCLUSIONS: The incidence and mortality rate of TBMV patients were high. Acute tuberculous pneumonia, underlying disease of AIDS, amount of acid fast bacilli, and delayed administration of anti-tuberculosis agents were independent risk factors to develop TBMV. Male gender, consolidation on chest X-ray, and low serum albumin were significantly related to mortality.
