Initial default among diagnosed sputum smear-positive pulmonary tuberculosis patients in Andhra Pradesh, India

Area of Science:

• Public Health
• Infectious Diseases
• Tuberculosis Control

Background:

• The Revised National TB Control Programme (RNTCP) in India defines 'initial defaulters' as smear-positive pulmonary tuberculosis (PTB) patients not confirmed to have started treatment.
• Understanding the reasons for treatment non-initiation is critical for improving TB control program effectiveness.

Purpose of the Study:

• To investigate the reasons behind treatment non-initiation among smear-positive PTB patients identified as initial defaulters under the RNTCP.
• To assess the magnitude of initial default in a specific region of India.

Main Methods:

• A cross-sectional survey was conducted in twenty districts of Andhra Pradesh, India.
• The study included all patients reported as initial defaulters between July and September 2006.
• Data collection involved verifying treatment status and identifying reasons for non-initiation.

Main Results:

• Out of 1304 reported initial defaulters, 47.5% were incorrectly reported, often due to poor documentation or delayed treatment initiation.
• Among the confirmed 685 initial defaulters (4.5% of total diagnosed), 51% were untraceable, 22% had died before treatment, and 13.5% cited other reasons like refusal.
• A significant proportion of initially reported defaulters were actually initiated on treatment, highlighting documentation issues.

Conclusions:

• Approximately 5% of diagnosed smear-positive PTB patients failed to initiate treatment under the RNTCP during the study period.
• Improving patient address recording systems is essential for patient retrieval and treatment adherence.
• Further research is needed on enhancing patient counseling to prevent initial default and understanding mortality before treatment initiation.
