Care-seeking pathways and diagnostic delays in extrapulmonary TB patients

This study was conducted at a private tertiary hospital engaged with the TB control programme in the city of Lahore, Pakistan.

To assess the healthcare-seeking pathways, different delays and factors associated with delays among the patients who presented in the outpatient department with tuberculous lymphadenitis and pleuritis, the most common manifestations of extrapulmonary TB.

This cross-sectional study was conducted prospectively from April 2016 to August 2017.

The median age of the 339 patients analysed was 22 years (IQR 17-30); tuberculous lymphadenitis was predominant in females (63%), while pleuritis affected more males (64%). Overall, 62% reported seeking care from healthcare providers before diagnosis, of whom 62% sought care from private facilities, 32% visited facilities >2 times and 8% visited traditional healers. Diagnostic delay was associated with tuberculous lymphadenitis, age 15-44 years, poor socio-economic status and poor TB knowledge.

There was considerable delay in the management of extrapulmonary TB patients, and the health-system delay was the major contributor, leading to increased patient suffering. Efforts towards minimising health-system delay need to be prioritised for patient screening and diagnosis, with a feasible algorithm that is workable in resource-limited settings.
