Abstract
AbstractIn resource-limited settings, point-of-care ultrasound (POCUS) has great potential to support the timely diagnosis of extrapulmonary tuberculosis (EPTB). We aim to determine the in-hospital mortality due to EPTB according to clinical and POCUS features and risk factors in newly diagnosed patients hospitalized for EPTB in Chókwè district, Mozambique. We analyzed routinely collected data from paper medical files and electronic POCUS records of EPTB in infected patients aged 15 years or older and admitted to Carmelo Hospital of Chókwè from 2016 to 2020. Kaplan–Meier survival curves and adjusted Cox regression analyses were used to model predictors of mortality and time to death. The 390 included in-patients with EPTB and POCUS data contributed a total of 6240 in-hospital person-days of observation. The overall mortality rate was 2.16 per 100 person-days. Adjusted Cox regression showed a higher risk of death in those with abdominal tenderness (adjusted hazard ratio [aHR] 1.61, 95% confidence interval [CI] 1.00–2.82, p = 0.050), antiretroviral treatment (ART) for more than 90 days (aHR 4.03, 95% CI 1.50–10.78, p = 0.006), and mixed patterns on kidney POCUS (aHR 2.91, 95% CI 1.38–6.10, p = 0.005). An optimal immunovirological response to ART was a protective factor against death [aHR] 0.12, 95% CI 0.04–0.35, p < 0.001). Variables associated with an increased risk of death were male gender, abdominal pain, ART for more than three months (with immunovirological failure or non-response to ART) and having a mixed pattern of kidney POCUS characteristics. Early detection of these risk factors may have a direct impact on reducing TB mortality, and the POCUS approach as a complementary diagnostic method for EPTB provides a simple, feasible and affordable intervention in resource-limited settings like Mozambique.
