Directly observed therapy (DOT) for tuberculosis showed similar cure and treatment completion rates compared to self-treatment. While DOT did not significantly improve outcomes, some studies suggest benefits in specific settings for tuberculosis treatment adherence.

Area of Science:

  • Public Health
  • Infectious Diseases
  • Clinical Trials

Background:

  • Tuberculosis treatment non-adherence affects up to 50% of patients.
  • Strategies to improve treatment adherence are crucial for tuberculosis control.

Purpose of the Study:

  • To compare directly observed therapy (DOT) with self-treatment for tuberculosis.
  • To evaluate the impact on cure and treatment completion rates.

Main Methods:

  • Systematic review of randomized and quasi-randomized trials.
  • Searched multiple databases including Cochrane, MEDLINE, and EMBASE.
  • Independent assessment of methodological quality and data extraction.

Main Results:

  • Six studies (n=1910) found DOT and self-treatment had similar cure and completion rates.

  • Stratified analysis by observer type (health worker, volunteer, family) showed no significant differences.
  • One study with patient choice of supervisor showed modest benefit in cure and completion.

    • Conclusions:

    • Well-conducted trials indicate directly observed therapy (DOT) has similar effects to self-administered treatment for tuberculosis.
    • Findings are consistent across low, middle, and high-income countries.
    • Direct observation did not significantly improve cure or treatment completion in most evaluated settings.
