Hypothesis

Can initial clinical presentations predict mortality in pulmonary tuberculosis patients?

Conclusion

Clinical presentations such as fever, anorexia, and the absence of chronic cough are independent predictors of mortality in pulmonary tuberculosis patients.

Supporting Evidence

  • Older age was associated with higher mortality (RR=1.04).
  • Malignancy increased mortality risk (RR=2.42).
  • Renal insufficiency was linked to higher mortality (RR=1.77).
  • Presence of fever was associated with increased mortality (HR=1.72).
  • Absence of chronic cough was linked to higher mortality (HR=0.54).

Takeaway

This study found that if a tuberculosis patient has a fever or doesn't have a chronic cough, they might be at a higher risk of dying from the disease.

Methodology

This was a prospective observational study that enrolled newly diagnosed, culture-proven pulmonary tuberculosis patients from six hospitals in Taiwan.

Potential Biases

The study was conducted in referral medical centers, which may not represent the general population of tuberculosis patients.

Limitations

The study may have overestimated mortality rates due to the inclusion of patients with more co-morbidities and higher disease severity.

Participant Demographics

Mean age was 64.6 years, predominantly male (77.6%), with 1.3% HIV-positive patients.
