Diagnosis delay in smear positive tuberculosis patients

Area of Science:

• Public Health
• Infectious Diseases
• Epidemiology

Background:

• Early diagnosis of tuberculosis (TB) is critical for effective TB control programs.
• Evaluating diagnostic delays is essential for assessing the performance of national TB programs.
• This study focuses on the Islamic Republic of Iran to understand TB diagnosis delays.

Purpose of the Study:

• To evaluate the diagnosis delay in smear-positive tuberculosis patients in Iran.
• To identify factors contributing to delayed TB diagnosis.

Main Methods:

• A cross-sectional study of smear-positive TB patients registered in Iran from March 20, 2009, to March 20, 2010.
• Diagnosis delay was defined as the time from symptom onset to TB confirmation.
• Statistical analysis included Mann-Whitney test, chi-square, and logistic regression.

Main Results:

• Diagnosis delay was significantly longer for females (58 days) compared to males (53 days).
• Non-Iranians (61 days), urban residents (59 days), and prisoners (37 days) experienced longer delays than their counterparts.
• Patients utilizing the private outpatient system (61 days) had longer delays than those using the public system (52 days).

Conclusions:

• Risk factors for delayed TB diagnosis include being non-Iranian, living in urban areas, not being a prisoner, and using the private healthcare system.
• Integrating the private healthcare sector through a public-private mix model is vital for successful national TB programs.
