Non-communicable comorbidities in pulmonary tuberculosis and healthcare utilization: a cross-sectional study of 2021 Indonesian national health insurance data

Abstract

BackgroundLimited research exists on the comorbidity of pulmonary tuberculosis with non-communicable diseases (NCDs) and its implications for healthcare utilization in Indonesia. The lack of investigation into NCD comorbidity among pulmonary tuberculosis patients could adversely affect both the healthcare system and the national health insurance scheme. Understanding the NCD comorbidity among pulmonary tuberculosis patients, associated factors, and healthcare utilization is crucial for ensuring the effective and efficient delivery of health services.MethodThis study utilized an observational cross-sectional design based on anonymized sample data from tuberculosis cases covered by Indonesia's National Health Insurance in 2021. Chi-square tests were employed to analyze dependent and independent variables, while unadjusted and adjusted logistic regressions were used to explore further associations.ResultsThe prevalence of NCD comorbidity in tuberculosis patients was 11.81%. Aged over 60 (aOR 5.16; [CI] 4.23—6.3), married (aOR 1.19; [CI] 1.05—1.34), and unemployed (aOR 1.27; [CI] 1.08—1.49) were associated with the NCD comorbidity in pulmonary tuberculosis patients. Factors associated with increased inpatient service utilization among pulmonary tuberculosis patients included aged over 60 (aOR 5.69; [CI] 4.81—6.74), male (aOR 1.32; [CI] 1.23—1.40), self-employment (aOR 1.42; [CI] 1.29—1.56), having insurance subsidized by central government (aOR 1.89; [CI] 1.73—2.08) or local government funds (aOR 1.75; [CI] 1.58—1.93), and having comorbidity non-communicable diseases (aOR 1.80; [CI] 1.66—1.96).ConclusionPulmonary tuberculosis patients exhibit a significant prevalence of NCD comorbidity, which substantially impacts healthcare utilization. Early detection and management of these conditions are critical to mitigate burdens on both the healthcare system and the financial sustainability of the national health insurance scheme. Integrating health services for tuberculosis and NCDs through bidirectional screening is essential for comprehensive patient care.
