Mortality and associated factors among people living with HIV admitted at a tertiary-care hospital in Uganda: a cross-sectional study

BACKGROUND

Hospital admission outcomes for people living with HIV (PLHIV) in resource-limited settings are understudied. We describe in-hospital mortality and associated clinical-demographic factors among PLHIV admitted at a tertiary-level public hospital in Uganda.

METHODS

We performed a cross-sectional analysis of routinely collected data for PLHIV admitted at Kiruddu National Referral Hospital between March 2020 and March 2023. We estimated the proportion of PLHIV who had died during hospitalization and performed logistic regression modelling to identify predictors of mortality.

RESULTS

Of the 5,827 hospitalized PLHIV, the median age was 39 years (interquartile range [IQR] 31-49) and 3,293 (56.51%) were female. The median CD4 + cell count was 109 cells/µL (IQR 25-343). At admission, 3,710 (63.67%) were active on antiretroviral therapy (ART); 1,144 (19.63%) had interrupted ART > 3 months and 973 (16.70%) were ART naïve. In-hospital mortality was 26% (1,524) with a median time-to-death of 3 days (IQR 1-7). Factors associated with mortality (with adjusted odds ratios) included ART interruption, 1.33, 95% confidence intervals (CI) 1.13-1.57, p 0.001; CD4 + counts ≤ 200 cells/µL 1.59, 95%CI 1.33-1.91, p < 0.001; undocumented CD4 + cell count status 2.08, 95%CI 1.73-2.50, p < 0.001; impaired function status 7.35, 95%CI 6.42-8.41, p < 0.001; COVID-19 1.70, 95%CI 1.22-2.37, p 0.002; liver disease 1.77, 95%CI 1.36-2.30, p < 0.001; co-infections 1.53, 95%CI 1.32-1.78, p < 0.001; home address > 20 km from hospital 1.23, 95%CI 1.04-1.46, p 0.014; hospital readmission 0.7, 95%CI 0.56-0.88, p 0.002; chronic lung disease 0.62, 95%CI 0.41-0.92, p 0.019; and neurologic disease 0.46, 95%CI 0.32-0.68, p < 0.001.

CONCLUSION

One in four admitted PLHIV die during hospitalization. Identification of risk factors (such as ART interruption, function impairment, low/undocumented CD4 + cell count), early diagnosis and treatment of co-infections and liver disease could improve outcomes.

Determinants to Continuation on Hiv Pre-exposure Propylaxis Among Female Sex Workers at a Referral Hospital in Uganda: a Mixed Methods Study Using Com-b Model

Background

Female sex workers (FSWs) have the highest HIV prevalence in Uganda. Pre exposure prophylaxis (PrEP) has been recommended as part of the HIV combination prevention strategy, with improved patient initiation, but continuation on the service is low. We evaluated PrEP continuation among FSWs and explored potential determinants of PrEP continuation within a public referral hospital in Urban Uganda.

Methods

An explanatory sequential mixed method study was conducted at Kiruddu National referral hospital in Uganda. Secondary data on social demographic characteristics and follow up outcomes of at least one year was collected for all FSWs who were initiated PrEP between May 2020 and April 2021.We used Kaplan-Meier survival analysis to evaluate continuation on PrEP from time of initiation and follow-up period. The capability, opportunity, and motivation to change behaviour model was used to explore perspectives and practices of FSWs (n = 24) and health care providers (n = 8) on continuation on PrEP among FSWs, using semi structured interviews. The qualitative data was deductively coded and analyzed thematically, categorizing the themes related to PrEP continuation as facilitators and barriers.

Results

Of the 292 FSWs initiated on PrEP during this period, 101 (34.6) % were active on PrEP, 137 (46.9%) were lost to follow-up, 45 (15.4%) were no longer eligible to continue PrEP, eight (2.7%) were transferred out and one (0.3%) had died. Median survival time on PrEP was 15 months (Interquartile range IQR, 3-21). The continuation rates on PrEP at six (6) and 12 months were, 61.1% and 53.1%, respectively. Facilitators of PrEP continuation included awareness of risk associated with sex work, integration of PrEP with other HIV prevention services, presence of PrEP Peer support and use of Drop-in centers. The barriers included low community awareness about PrEP, high mobility of sex workers, substance abuse, and the unfavorable daytime clinic schedules.

Conclusion

Continuation on PrEP remains low among FSWs. Interventions for PrEP continuation should address barriers such as low community awareness on PrEP, substance abuse and restrictive health facility policies for scale of the PrEP program among FSWs in Uganda. Integration of PrEP with other services and scale up of community PrEP delivery structures may improve its continuation.
