Directly observed therapy (DOT) for tuberculosis (TB) did not improve cure or treatment completion rates in low and middle-income countries. Patient choice of supervisor in one study showed modest benefits, but overall evidence is lacking for DOT effectiveness.

Area of Science:

  • Public Health
  • Infectious Diseases
  • Clinical Trials

Background:

  • Tuberculosis (TB) treatment non-completion affects up to 50% of patients.
  • Improving adherence to TB treatment and diagnostic regimens is crucial.

Purpose of the Study:

  • To evaluate the impact of directly observed therapy (DOT) on tuberculosis cure and treatment completion.
  • Assessed DOT effectiveness when administered by health workers, community volunteers, or family members.

Main Methods:

  • Systematic review and meta-analysis of randomized and quasi-randomized controlled trials.
  • Searched multiple databases including Cochrane, MEDLINE, EMBASE, and LILACS.
  • Two independent reviewers assessed trial quality and extracted data.

Main Results:

  • Four studies (1603 participants) were included in the analysis.
  • No significant difference in cure or treatment completion rates between DOT and self-treatment.
  • One study with patient choice of supervisor showed a modest benefit.

Conclusions:

  • Current evidence does not support the effectiveness of DOT in improving TB cure or treatment completion in low and middle-income settings.
  • Further research may be needed to identify specific contexts or patient groups where DOT could be beneficial.
