Primary Institution: KNCV Tuberculosis Foundation

Hypothesis

High mortality rates would indicate long diagnostic delay.

Conclusion

Diagnostic delay is not associated with treatment mortality in Vietnam, suggesting that high case fatality should not be used as an indicator of long diagnostic delay.

Supporting Evidence

  • Fatality was 4.4% among the studied patients.
  • Fatality did not correlate with diagnostic delay at the district level.
  • The study included 1,881 patients with complete data.

Takeaway

This study found that waiting a long time to get treated for tuberculosis doesn't mean more people will die from it.

Methodology

A cohort of 2,093 patients was followed, with data on diagnosis and treatment extracted from routine registers.

Potential Biases

Recall bias may have affected the accuracy of reported diagnostic delays.

Limitations

The study may not represent patients who did not start treatment or those treated in specialized hospitals.

Participant Demographics

Patients aged ≥ 15 years with newly diagnosed smear-positive pulmonary tuberculosis.
