Patients cause half of the delays in diagnosing pulmonary tuberculosis (PTB). Doctors account for most of the healthcare system

Area of Science:

  • Pulmonary Medicine
  • Infectious Diseases
  • Public Health

Context:

  • Symptomatic pulmonary tuberculosis (PTB) diagnosis is often delayed.
  • Understanding diagnostic delay components is crucial for timely treatment initiation.
  • Previous studies have not fully elucidated the specific contributions to PTB diagnostic delays.

Purpose:

  • To investigate the factors contributing to diagnostic delays in symptomatic pulmonary tuberculosis (PTB).
  • To analyze patient delay (PD), doctor delay (DD), diagnostic process delay (DPD), and healthcare system delay (HCSD).
  • To determine the total delay (TD) from symptom onset to PTB treatment initiation.

Summary:

  • A prospective study of 287 new symptomatic PTB cases (age ≥15) analyzed delays using structured interviews.

  • Mean delays were: TD 81.8 days, PD 43.3 days, DD 28.4 days, DPD 10.0 days, and HCSD 38.5 days.
  • Patients accounted for 50% of excess diagnostic delay; doctors were responsible for 75% of system-related delays.

    • Impact:

    • Findings highlight significant patient and healthcare system contributions to PTB diagnostic delays.
    • Interventions targeting patient awareness and healthcare provider efficiency are needed to reduce PTB diagnosis time.
    • Reducing diagnostic delays can improve PTB treatment outcomes and limit disease transmission.
