Analysis of Risk Factors and Predictors of Success in Controlling Drop Out Pulmonary Tuberculosis: An Observational Study in Batang Regency, Indonesia

Abstract

Introduction: Pulmonary tuberculosis (TB) remains a significant public health problem in Batang Regency, Indonesia. The high drop out (DO) rate of treatment is one of the main obstacles in controlling TB. This study aims to identify risk factors and predictors of DO for pulmonary TB treatment in Batang Regency. Methods: An analytical observational study with a cross-sectional design was conducted in 2023 involving 150 pulmonary TB patients who were recorded as having DO in the 2021-2022 period. Primary data was collected through interviews and secondary data from medical records. Bivariate analysis using the Chi-square test or Fisher's exact test, and multivariate analysis using logistic regression were performed to identify risk factors and predictors of DO. Results: Bivariate analysis showed that young age (<25 years) (OR = 3.21; 95% CI: 1.54-6.69), long distance of residence from health facilities (OR = 4.12; 95% CI: 1.98-8.57), and a history of adverse drug reactions (ESO) (OR = 5.63; 95% CI: 2.65-11.94) were significant risk factors for DO. Multivariate analysis confirmed that young age (aOR = 2.95; 95% CI: 1.35-6.43), long distance of residence (aOR = 3.88; 95% CI: 1.79-8.41), and history of ESO (aOR = 5.12; 95% CI: 2.38-11.01) were independent predictors of DO. Conclusion: Young age, long distance of residence from health facilities, and history of ESO are risk factors and independent predictors of DO for pulmonary TB treatment in Batang Regency. Interventions that target these factors, such as intensive education and counseling for young patients, increased access to health services, and optimal management of ESO, are needed to increase the success of TB control.
