Extra-pulmonary Tuberculosis among Tuberculosis Patients Visiting a Tertiary Care Centre: A Descriptive Cross-sectional Study

Introduction: Tuberculosis outside of the lung is extrapulmonary tuberculosis. The diagnosis of extrapulmonary tuberculosis is not easy in a community setting even in district hospitals. Clinical symptoms and radiological diagnosis are effective for the diagnosis of pulmonary and extra-pulmonary cases. The aim of the study is to find out the prevalence of extra-pulmonary tuberculosis among tuberculosis patients visiting a tertiary care centre. Methods: This was a descriptive cross-sectional study conducted among the patient visiting a tertiary care centre from August 2019 to January 2020 after taking ethical approval from Institutional Review Committe (Reference number: 86) which observed different clinicoradiological and laboratory features in patients with extrapulmonary tuberculosis to address their respective accuracy and usability in measuring the burden of tuberculosis. The interview was taken for the symptoms, and then radiological and laboratory data were collected. Convenience sampling was used. Point estimate and 95% confidence interval were calculated. Results: Out of 60 patients with tuberculosis, 39 (65%) (62.83-67.17, 95% Confidence Interval) were diagnosed with extrapulmonary tuberculosis. Among them, 30 (76.9%) were with pleural effusions followed by lymphadenopathy in 9 (23.07%). Conclusions: The prevalence of extra-pulmonary tuberculosis was found to be higher as compared to the study done in similar settings
