Popis: | BackgroundTuberculosis (TB) remains a significant public health concern, and a leading cause of ill-health and death globally. More so, People living with HIV have been shown to carry an increased risk of developing TB with an estimated one-third of deaths in this population. The World Health Organization recommends systematic and routine screening of PLHIV for TB on every clinic visit and further testing using sputum for those with a positive TB screen test. Not all PLHIV with a positive TB screen test in Ghana are further tested for TB using sputum and the factors for this are not well understood. This study assessed factors associated with sputum ordering for TB diagnosis in PLHIV who were screened positive for TB in three hospitals providing HIV care and treatment services in the Greater Accra region of Ghana.MethodsMixed method study performed at three purposively selected hospitals providing HIV care and treatment services in the Greater Accra region. The study involved a cross sectional review of patients’ charts and in-depth interviews with health workers involved in the care and treatment of PLHIV. Quantitative data was analyzed using STATA version 15. Chi square test was used for bivariate analysis. Logistic regression was used for multivariate analysis. P≤ 0.05 was considered statistically significant. Inductive thematic analysis was used to determine emerging themes from the interviews. The major themes were represented with representative quotations.ResultsFour hundred (400) patient charts were reviewed of which 67.7% were female with median age of 39 (IQR 31-49). TB screening was recorded in 78% (95% CI 73.6, 82.0) of the patients of whom ninety-two (92) patients had a positive TB screen test. Only 53 (57.6%) who had a positive screen test had sputum ordered for further TB testing. In the multivariate analysis, patient general appearance described as abnormal (OR=3.05, p=0.036), having more than one TB symptom (OR=3.42, p=0.028) and presence of an alternative presumptive diagnosis (OR=0.34, p=0.023) were associated with having a sputum test ordered. High patient numbers, inability to produce sputum, unwillingness of the not so sick patients to provide sputum and the costs associated with chest X-ray were perceived as the challenges to further testing for TB.ConclusionTB screening in PLHIV is still lower than recommended and almost half of PLHIV with a positive TB screen test did not have a sputum test documented. Sputum testing was likely to be done in patients with an abnormal general appearance and more than one TB symptom and unlikely in those with an alternative presumptive diagnosis. High workload, costs of TB tests, lack of training for health workers and inability to produce sputum by patients were the barriers to sputum testing highlighted by the health workers. |
