Summary

Simple interventions significantly improved tuberculosis cure rates in Mzuzu, demonstrating that effective tuberculosis control is achievable even with high HIV prevalence through enhanced program evaluation and supervision.

Area of Science:

  • Public Health
  • Infectious Disease Control
  • Program Evaluation

Background:

  • District-level tuberculosis (TB) control programs often face challenges in achieving high cure rates.
  • High human immunodeficiency virus (HIV) seroprevalence, as seen in Mzuzu (67% among TB patients), can complicate TB treatment outcomes.

Purpose of the Study:

  • To identify reasons for low TB cure rates in a district-level program.
  • To develop, implement, and assess interventions aimed at improving TB cure rates.

Main Methods:

  • The study was conducted in Mzuzu, a district with high TB incidence and HIV prevalence.
  • Case-holding activities were examined, and interventions focused on improving training, supervision, patient address recording, and adherence to protocols.

Main Results:

  • The TB cure rate increased from 24% to 68% after implementing interventions.
  • The cure rate among survivors to end of treatment rose from 29% to 92%.

Conclusions:

  • Simple, cost-effective local interventions can substantially enhance TB case holding.
  • The study highlights the critical need for ongoing evaluation, training, and supervision in TB control programs.
