1National Department of Health, Kerema District, Gulf Province, Papua New Guinea (PNG).
Setting:
Gulf Province, a rural area of mainland Papua New Guinea, is known to have one of the highest burdens of tuberculosis (TB) in the country.
Objectives:
To describe the characteristics and outcomes of TB patients registered for first-line treatment in Kerema General Hospital in Gulf Province between January and December 2016.
Design:
This was a retrospective cohort study using routinely collected programme data.
Results:
Of 347 cases with a recorded TB site, 54% were male and 32% were aged <15 years. No human immunodeficiency virus (HIV) status was recorded for 51% of cases. TB was bacteriologically confirmed in 23% of cases. Among the cohort, there were 145 extrapulmonary TB cases (42%); the site of disease was unknown in 56% of these cases. Of the 297 cases with treatment outcome evaluated, 56% had a favourable outcome and 26% were lost to follow-up. On multivariable analysis, extrapulmonary TB (adjusted OR [aOR] 0.51, 95%CI 0.30-0.88, P = 0.02) and bacteriologically confirmed TB (aOR 0.40, 95%CI 0.21-0.77, P < 0.01) were associated with decreased odds of an unfavourable treatment outcome.
Conclusion:
The study findings highlight the need to improve TB diagnosis, access to HIV testing, treatment adherence, patient support and the quality of TB programme data in Gulf Province.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
