Item 2353.Distance and Time to Clinic Are Associated with Increased Risk of Detectable HIV-1 Viral Load at a Peripheral Health Center in Rural Western Uganda(US: Oxford University Press., 2022) Hendren, Cate; Ndizeye, Ronnie; Mumbere, Nobert; Rubinstein, Rebecca J.; Baguma, Emma; Muhindo, Rabbison; Goel, Varun; Ntaro, Moses; Siedner, Mark; Mulogo, EdgarAntiretroviral therapy (ART) improves the health of people living with HIV (PLHIV) and reduces HIV transmission. While availability and efficacy of ART have improved in sub-Saharan Africa (SSA), access remains a challenge. Travel burden, measured as travel time, distance, and cost, has been posited as a potential barrier to ART. For example, a previous study at a large, urban referral center in Uganda showed GPS-measured distance was associated with clinic absenteeism. However, others suggest that PLHIV are willing to travel farther for HIV care because of stigma or for higher quality care. Less is known about the effect of travel burden in rural settings where transportation infrastructure is sparse, and there are few transportation options. Therefore, the objective of this study funded by the IDSA GERM Program was to explore potential associations between distance- and time-to-clinic in a highland area of rural western Uganda with HIV outcomes including viral suppression.Item Community health workers trained to conduct verbal autopsies provide better mortality measures than existing surveillance: Results from a cross-sectional study in rural western Uganda(PLoS ONE, 2019) Nabukalu, Doreen; Ntaro, Moses; Seviiri, Mathias; Reyes, Raquel; Wiens, Matthew; Sundararajan, Radhika; Mulogo, Edgar; Boyce, Ross M.In much of sub-Saharan Africa, health facilities serve as the primary source of routine vital statistics. These passive surveillance systems, however, are plagued by infrequent and unreliable reporting and do not capture events that occur outside of the formal health sector. Verbal autopsies (VA) have been utilized to estimate the burden and causes of mortality where civil registration and vital statistics systems are weak, but VAs have not been widely employed in national surveillance systems. In response, we trained lay community health workers (CHW) in a rural sub-county of western Uganda to conduct VA interviews in order to assess the feasibility of leveraging CHW to measure the burden of disease in resource limited settings. Methods and findings Trained CHWs conducted a cross-sectional survey of the 36 villages comprising the Bugoye sub-county to identify all deaths occurring in the prior year. The sub county has an estimated population of 50,249, approximately one-quarter of whom are children under 5 years of age (25.3%). When an eligible death was reported, CHWs administered a WHO 2014 VA questionnaire, the results of which were analyzed using the InterVA-4 tool. To compare the findings of the CHW survey to existing surveillance systems, study staff reviewed inpatient registers from neighboring referral health facilities in an attempt to match recorded deaths to those identified by the survey. Overall, CHWs conducted high quality VA interviews on direct observation, identifying 230 deaths that occurred within the sub-county, including 77 (33.5%) among children under five years of age. More than half of the deaths (123 of 230, 53.5%) were reported to have occurred outside a health facility and thus would not be captured by passive surveillance. More than two-thirds (73 of 107, 68.2%) of facility deaths took place in one of three nearby hospitals, yet only 35 (47.9%) were identified on our review of inpatient registers. Consistent with previous VA studies, the leading causes of death among children under five years of age were malaria (19.5%), prematurity (19.5%), and neonatal pneumonia (15.6%). while among adults, HIV/AIDS-related deaths illness (13.6%), pulmonary tuberculosis (11.4%) and malaria (8.6%) were the leading causes of death. No child deaths identified from inpatient registers listed HIV/AIDS as a cause of death despite 8 deaths (10.4%) attributed to HIV/AIDS as determined by VA. Conclusions Lay CHWs are able to conduct high quality VA interviews to capture critical information that can be analyzed using standard methodologies to provide a more complete estimate of the burden and causes of mortality. Similar approaches can be scaled to improve the measurement of vital statistics in order to facilitate appropriate public health interventions in rural areas of sub-Saharan Africa.Item Effectiveness of a mobile antiretroviral pharmacy and HIV care intervention on the continuum of HIV care in rural Uganda(AIDS care, 2020) Bajunirwe, Francis; Ayebazibwe, Nicholas; Mulogo, Edgar; Eng, Maria; McGrath, Janet; Kaawa-Mafigiri, David; Mugyenyi, Peter; Sethi, Ajay K.Adherence to antiretroviral therapy (ART) is critical in order to achieve viral suppression. We designed an intervention, Mobile Antiretroviral Therapy and HIV care (MAP-HC) in rural southwestern Uganda aimed to reduce travel distance and hypothesized that MAP-HC would improve ART adherence and rates of viral load suppression. The study was conducted at two district hospitals, among patients who lived >5 km from the hospital. For each hospital, we identified 4 health centers in the catchment area to serve as site for the mobile pharmacy. Each site was visited once a month to provide ART refills and adherence counseling. We measured patient waiting time, adherence and viral load suppression before and after the intervention. The proportion of patients who missed an ART dose in the last 30 days dropped from 20% to 8.5% at 12 months post-intervention (p = 0.009) and those with detectable viral load dropped from 19.9% to 7.4% (p = 0.001), however, mean waiting time increased from 4.48 to 4.76 h (p = 0.13). Mobile pharmacy intervention in rural Uganda is feasible and resulted in improvement in adherence and viral load suppression. Although it did not reduce patient waiting time at the clinic, we recommend scale-up in rural areas where patients face transportation challenges.Item Erratum for Ciccone et al., “Rapid Diagnostic Tests to Guide Case Management of and Improve Antibiotic Stewardship for Pediatric Acute Respiratory Illnesses in Resource-Constrained Settings: a Prospective Cohort Study in Southwestern Uganda”(Microbiology Spectrum, 2022) Ciccone, Emily J.; Kabugho, Lydia; Baguma, Emmanuel; Muhindo, Rabbison; Juliano, Jonathan J.; Mulogo, Edgar; Boyce, Ross M.Pediatric acute respiratory illness (ARI) is one of the most common reasons for evaluation at peripheral health centers in sub-Saharan Africa and is frequently managed based on clinical syndrome alone. Although most ARI episodes are likely caused by self-limited viral infections, the majority are treated with antibiotics. This overuse contributes to the development of antimicrobial resistance. To evaluate the preliminary feasibility and potential impact of adding pathogen-specific and clinical biomarker diagnostic testing to existing clinical management algorithms, we conducted a prospective, observational cohort study of 225 children presenting with malaria-negative, febrile ARI to the outpatient department of a semi-urban peripheral health facility in southwestern Uganda from October 2019 to January 2020. In addition to routine clinical evaluation, we performed influenza and Streptococcus pneumoniae antigen testing and measured levels of C-reactive protein, procalcitonin, and lactate in the clinic’s laboratory, and conducted a follow-up assessment by phone 7 days later. Almost one-fifth of participants (40/225) tested positive for influenza. Clinical biomarker measurements were low with C-reactive protein of >40 mg/L in only 11% (13/222) of participants and procalcitonin >0.25 ng/mL in only 13% (16/125). All but two children received antibiotic treatment; only 3% (7/225) were admitted. At follow-up, 59% (118/201) of caregivers reported at least one persistent symptom, but fever had resolved for all children. Positive influenza testing was associated with persistent symptoms. In summary, we demonstrate that simple, rapid pathogen-specific testing and biomarker measurement are possible in resource-limited settings and could improve syndromic management and, in turn, antibiotic stewardship.Item High Baseline CD4 Count and Exclusive Breastfeeding Are Associated with Lower Rates of Mother to Child HIV Transmission in Northwestern Uganda: A Two-Year Retrospective Cohort Study(Advances in Public Health, 2018) Izudi, Jonathan; Apangu, Pontius; Bajunirwe, Francis; Mulogo, Edgar; Batwala, VincentUnder Option B plus, the transmission of Human Immunodeficiency Virus (HIV) along the Early Infant Diagnosis (EID) of HIV cascade remains unknown. We described HIV transmission along the EID cascade and determined associated factors at Arua Regional Referral Hospital, Northwestern Uganda. Methods. Data on 295 mother-baby pairs in EID care (January 2014 and April 2015) was extracted, cleaned, and analysed in STATA. Univariate, bivariate, and multivariate analyses were performed. Independently associated factors were stated in adjusted odds ratio (AOR), 95% confidence interval (CI), and -values. Results. 233 (89.0%) mothers were above 30 years, 251 (85.1%) were in World Health Organization (WHO) clinical stages I/II at enrolment, 170 (57.6%) attended antenatal care (ANC) visits during recent pregnancy, and 204 (69.1%) delivered in a health facility. Meanwhile, 257 (87.1%) HIV Exposed Infants (HEIs) received Nevirapine prophylaxis from birth up to 6 weeks and 245 (83.0%) were exclusively breastfed during the first 6 months. Of 295 mother-baby pairs, 25 (8.5%) HEIs turned HIV-positive along the EID cascade. Baseline maternal CD4 count of more than 500 cells/ul compared to less than 500 cells/ul (adjusted odds ratio (AOR) = 0.29; 95% Confidence Interval (CI): 0.10–0.85; = 0.024) and exclusive breastfeeding (EBF) in the first 6 months of delivery in contrast to not EBF in the first 6 months (AOR = 0.17; 95% CI: 0.52–0.55; = 0.003) reduced HIV transmission. Meanwhile, ANC visits, place of delivery, time of Nevirapine initiation, and maternal antiretroviral therapy use were not significantly associated with infant HIV transmission. Conclusion. HIV transmission was high. High baseline CD4 count and exclusive breastfeeding reduced HIV transmission.Item Predictors of sleeping under cost-free mosquito bed nets among children under-five years in Mbarara, Uganda: a household survey(African Health Sciences, 2019) Andinda, Maureen; Mulogo, Edgar; Turyakira, Eleanor; Batwala, VincentIn 2010, Uganda Malaria Control Programme distributed cost-free mosquito bed nets to households with children under-five years and pregnant women in selected sub-counties. We assessed the factors associated with sleeping under costfree mosquito nets among children under-five years in Nyakayojo sub-county, Mbarara District, Uganda. Methods: 381 households with at least a child under-five years and benefited from cost-free bed nets in Nyakayojo were randomly selected. Caregivers of children were interviewed using a questionnaire. Results: 74% children slept under bed nets a night before the study. Children from households with ≥2 nets [aOR=1.75; 95% CI: 1.09-2.81, p=0.02], female caregiver [aOR=2.11; 95% CI: 1.16-3.79, p=0.01] and children from households that did not face problems (skin irritation, torn nets, suffocation, night sweating, nasal congestion and candle fire) when sleeping under bed nets [aOR=1.81; 95% CI: 1.10-2.98, p=0.02] were more likely to use nets. Main reason for not sleeping under a net was damage to the net (47.1%). Conclusion: The proportion of children sleeping under nets was comparable to MDG target. Improvements in use of mosquito nets by children can be achieved through increasing number of nets in a household.Item Rapid Diagnostic Tests to Guide Case Management of and Improve Antibiotic Stewardship for Pediatric Acute Respiratory Illnesses in Resource-Constrained Settings: a Prospective Cohort Study in Southwestern Uganda(Microbiology Spectrum, 2021) Ciccone, Emily J.; Kabugho, Lydia; Baguma, Emmanuel; Muhindo, Rabbison; Juliano, Jonathan J.; Mulogo, Edgar; Boyce, Ross M.Pediatric acute respiratory illness (ARI) is one of the most common reasons for evaluation at peripheral health centers in sub-Saharan Africa and is frequently managed based on clinical syndrome alone.

Data on retention of HEIs at large referral hospitals in Uganda is limited. We investigated the retention level of HEIs and associated factors. We conducted a retrospective cohort study on 352 HEIs in care (January 2014 and April 2015) at Arua Regional Referral Hospital, North-western Uganda. Electronic medical data were retrieved and analyzed with Stata. Chi-square, Fisher’s exact, and Students t-tests were used for bivariate analysis. Logistic regression was performed to determine factors independently associated with retention. 236 (67.0%) HEIs were delivered in a health facility and 306 (86.9%) received Nevirapine prophylaxis from birth until 6-weeks. Of mothers, 270 (76.7%) were 25–46 years, 202 (57.4%) attended antenatal care (ANC) at recent pregnancy, and 328 (93.2%) were on life-long anti-retroviral therapy. At 18-months, 277 (78.7%) HEIs were retained in care. Maternal age (25–46 years) (Adjusted Odds Ratio (AOR), 2.32; 95% CI, 1.32–4.06), ANC attendance during recent pregnancy (AOR, 2.01; 95% CI, 1.19–4.3.41) and Nevirapine prophylaxis initiation from birth until 6-weeks (AOR, 3.07; 95% CI, 1.50–6.26) were associated with retention. Retention was suboptimal. Older maternal age, ANC visits at last pregnancy, and timely NVP initiation increased retentionItem Retention of HIV exposed infants in care at Arua regional referral hospital, Uganda: a retrospective cohort study(BMC public health, 2019) Apangu, Pontius; Izudi, Jonathan; Bajunirwe, Francis; Mulogo, Edgar; Batwala, VincentRetention of HIV Exposed Infants (HEIs) in care ensures adequate care.

We aimed to assess the causes of mortality of children younger than 5 years at household level in Bugoye subcounty, Uganda. Methods This cross-sectional study was done in all 35 villages of Bugoye subcounty in March and April, 2017. Community health workers collected data on all deaths in all households of the subcounty that occurred between Jan 1, 2016, and Jan 1, 2017, using 2014 WHO standardised verbal autopsy (VA) questionnaires. Causes of death were determined using the InterVA-4 algorithm and cause-specific mortality proportions were calculated using STATA. Findings The VA survey identified 77 deaths among children younger than 5 years that occurred during the study period. Nearly half of these deaths occurred among neonates (n=38 [49%]), followed by ages 1–11 months (n=21 [27%]), and 1–4 years (n=18 [23%]). Among neonates, mortality most commonly occurred in the first 24 h (n=17 [22%]), followed by 8–28 days (n=10 [13%]). The five leading causes of death for all ages were malaria (19%), prematurity (19%), neonatal pneumonia (16%), HIV/AIDS-related illnesses (10%), and acute respiratory tract infections including pneumonia (9%). Malaria was the dominant cause of death for those aged 1–11 months and 1–4 years, accounting for 44% and 33%, respectively. Prematurity and neonatal pneumonia were the leading causes of death among neonates. Most deaths (81%) captured from the VAs could not be traced from the records of the reported health facilities in the district. Interpretation There is a considerable discrepancy between mortality captured by the district and mortality in the communities. Interventions that address common causes of mortality for children younger than 5 years need to be strengthened and extended to rural health facilities. Community death registration systems are lacking and in need of revitalisation. VA surveys could be conducted by district health authorities periodically to collect mortality data in the rural and hard-to-reach areas.
