Missed Opportunities in Tuberculosis Investigation and Associated Factors at Public Health Facilities in Uganda 

Abstract

Abstract; BackgroundThe incidence of tuberculosis (TB) is high in Uganda; yet, TB case detection is low. A recent national TB prevalence survey revealed that only 16% of presumptive TB patients seeking care at health facilities were offered sputum microscopy or chest-X ray (CXR). The objective of this study was to determine the magnitude of, and patient factors associated with missed opportunities in TB investigation at public health facilities of Wakiso District in Uganda.MethodsA facility-based cross-sectional survey was conducted at 10 high volume public health facilities offering comprehensive TB services in Wakiso, Uganda, among adults (≥18 years) with at least one symptom suggestive of TB predefined according to World Health Organisation criteria. Using exit interviews, data on demographics, TB symptoms, and clinical data relevant to TB were collected. A missed opportunity in TB investigation was defined as a patient with symptoms suggestive of TB who did not have sputum and/or CXR evaluation to rule out TB. Poisson regression analysis was performed to determine factors associated with missed opportunities in TB investigation using STATA 14.ResultsTwo hundred forty seven presumptive TB patients were recruited into this study exiting at antiretroviral therapy (ART) clinics (n=132) or general outpatient clinics (n=115) at public health facilities. Majority of participants were females (161/247, 65.2%) and the mean +SD age was 35.1 + 11.5 years. Sputum and/or CXR were not requested from 138 (55.9%) patients with symptoms suggestive of TB disease. Patients who did not inform health workers about TB related symptoms were more likely to miss a TB investigation (adjusted prevalence ratio: 1.68, 95%CI; 1.36-2.08, P<0.001). Conclusion; A large proportion of patients with symptoms suggestive of TB did not have sputum and/ or CXR requested for investigation. Patients who did not inform health workers about their TB related symptoms were more likely to miss having sputum and/ or CXR requested. We recommend studies to explore barriers and facilitators of disclosure of TB symptoms to enable formulation of effective interventions to empower people to improve likelihood of disclosing TB related symptoms.
