Tracing as part of tuberculosis control in a rural Cambodian district during 1992

Area of Science:

• Public Health
• Infectious Disease Control
• Epidemiology

Background:

• Tuberculosis (TB) control programs face challenges with patient adherence and treatment completion, particularly in rural settings.
• Patient non-adherence and loss to follow-up hinder effective TB management and disease containment.
• Understanding factors contributing to non-adherence is crucial for developing targeted interventions.

Purpose of the Study:

• To evaluate the effectiveness of a district-based tracing program designed to enhance TB treatment outcomes in rural Cambodia.
• To identify specific factors influencing patient non-adherence to TB therapy.
• To assess the rate of patient return to treatment after being traced.

Main Methods:

• A cohort analysis was conducted on all TB patients initiating treatment in 1992 in Banteay Meas district, Cambodia.
• Patients who absconded from treatment were traced and followed as a separate cohort.
• Treatment outcomes and reasons for non-adherence were systematically recorded and analyzed.

Main Results:

• The tracing program successfully re-engaged 81% of absconded patients met at home.
• Socioeconomic factors were the primary reported reasons for non-adherence (68%), not distance.
• Cohort analysis revealed improvements in TB treatment completion rates and a significant decrease in the absconding rate.

Conclusions:

• District-based patient tracing is an effective strategy for improving TB treatment adherence and completion in rural Cambodia.
• The program demonstrated success in re-engaging patients and strengthening the overall TB control program at the district level.
• Addressing socioeconomic determinants of non-adherence is vital for successful TB treatment outcomes.
