Area of Science:

  • Public Health
  • Infectious Diseases
  • Respiratory Medicine

Background:

  • Timely diagnosis and treatment are critical for managing pulmonary tuberculosis (TB).
  • Delays in case-finding contribute to disease progression and transmission.
  • Understanding patient and doctor delays is essential for improving TB control strategies.

Purpose of the Study:

  • To analyze patient and doctor delays in the diagnosis of pulmonary tuberculosis.
  • To identify factors contributing to delays in seeking medical care and receiving a diagnosis.
  • To evaluate the impact of healthcare facility type on diagnostic timeliness.

Main Methods:

  • Retrospective study of 100 consecutive pulmonary tuberculosis patients at Penang Hospital Chest Clinic.
  • Analysis of time from illness onset to initial consultation (patient delay) and from consultation to diagnosis (doctor delay).
  • Assessment of demographic factors, initial healthcare seeking behavior, and diagnostic investigations.

Main Results:

  • Median patient delay was two weeks, longer in males, less educated, and drug abusers.
  • Median doctor delay resulted in only 47% of patients diagnosed and treated within one month.
  • Patients initially seeking care at private practices experienced longer doctor delays and fewer appropriate investigations (sputum exam, chest X-ray).

Conclusions:

  • Significant patient and doctor delays contribute to advanced tuberculosis at diagnosis.
  • Healthcare providers, particularly in the private sector, require enhanced awareness of TB diagnosis and management.
  • Public health education campaigns are needed to reduce patient delay and encourage prompt medical consultation.
