Hypothesis

What is the prevalence of multidrug-resistant tuberculosis (MDR-TB) among Category II pulmonary tuberculosis patients?

Conclusion

The study found a significant prevalence of MDR-TB at 20.4% among Category II pulmonary tuberculosis patients.

Supporting Evidence

  • 40 out of 196 patients had MDR-TB, indicating a prevalence of 20.4%.
  • The mean age of MDR-TB patients was 33.25 years.
  • 9 patients (22.5%) were female.
  • 36 patients showed resistance to rifampicin and isoniazid.

Takeaway

This study shows that many patients who have had tuberculosis before are now getting a tougher version of the disease that is harder to treat.

Methodology

A cross-sectional, descriptive study involving sputum-positive Category II pulmonary TB patients diagnosed between 2005 and 2008.

Potential Biases

Referral bias due to the hospital-based nature of the study.

Limitations

The study is hospital-based, which may introduce referral bias, and results may not be applicable to all Category II patients in India.

Participant Demographics

Mean age of participants was 33.25 years, with 22.5% being female.
