Hepatitis B vaccination status and associated factors among undergraduate students of Makerere University College of Health Sciences

Background

Hepatitis B is a global health problem. Trainees in the health-related fields are exposed to occupational risk of Hepatitis B Virus. In Uganda, there is scarcity of information on vaccination among students in health-care. The objective of this study was to assess hepatitis B vaccination status of the students and factors associated.

Methods and findings

This was a cross sectional study, conducted at Makerere University College of Health Sciences among undergraduate students who were eligible. A self-report on Hepatitis B vaccination status and various characteristics were collected on each participant, using a standardized structured self-administered questionnaire. Descriptive statistics were computed, bivariate and multivariate analysis were done using Stata 14.

Results

Out of 760 participants, 44.3% (95% CI 35.2–52.8) reported full vaccination. Vaccination was associated with gender, course, year of study and student’s sponsorship. Males were less likely to be vaccinated, Prevalence Ratio (PR) 0.79; P-value <0.001, while self-sponsored students were also most likely to be vaccinated, PR 2.08; P-value <0.001. About 37% reported an accidental needle injury during their training.

Conclusion

Full vaccination was low and given the high prevalence of needle injuries, it raises a safety concern. Vaccination should be mandatory for all students prior to clinical exposure. There is need for targeted interventions to increase uptake.

Incidence and predictors of first line antiretroviral regimen modification in western Kenya

Background

Limited antiretroviral treatment regimens in resource-limited settings require long-term sustainability of patients on the few available options. We evaluated the incidence and predictors of combined antiretroviral treatment (cART) modifications, in an outpatient cohort of 955 patients who initiated cART between January 2009 and January 2011 in western Kenya.

Methods

cART modification was defined as either first time single drug substitution or switch. Incidence rates were determined by Poisson regression and risk factor analysis assessed using multivariate Cox regression modeling.

Results

Over a median follow-up period of 10.7 months, 178 (18.7%) patients modified regimens (incidence rate (IR); 18.6 per 100 person years [95% CI: 16.2–21.8]). Toxicity was the most common cited reason (66.3%). In adjusted multivariate Cox piecewise regression model, WHO disease stage III/IV (aHR; 1.82, 95%CI: 1.25–2.66), stavudine (d4T) use (aHR; 2.21 95%CI: 1.49–3.30) and increase in age (aHR; 1.02, 95%CI: 1.0–1.04) were associated with increased risk of treatment modification within the first year post-cART. Zidovudine (AZT) and tenofovir (TDF) use had a reduced risk for modification (aHR; 0.60 95%CI: 0.38–0.96 and aHR; 0.51 95%CI: 0.29–0.91 respectively). Beyond one year of treatment, d4T use (aHR; 2.75, 95% CI: 1.25–6.05), baseline CD4 counts ≤350 cells/mm³ (aHR; 2.45, 95%CI: 1.14–5.26), increase in age (aHR; 1.05 95%CI: 1.02–1.07) and high baseline weight >60kg aHR; 2.69 95% CI: 1.58–4.59) were associated with risk of cART modification.

Conclusions

Early treatment initiation at higher CD4 counts and avoiding d4T use may reduce treatment modification and subsequently improve sustainability of patients on the available limited options.

Risk factors, person, place and time characteristics associated with Hepatitis E Virus outbreak in Napak District, Uganda

BACKGROUND

Hepatitis E is self-limiting, but can cause death in most at risk groups like pregnant women and those with preexisting acute liver disease. In developing countries it presents as epidemic, in 2014 Hepatitis E Virus (HEV) outbreak was reported in Napak district Uganda. The role of factors in this setting that might have propagated this HEV epidemic, including host, agent, and environmental characteristics, were still not clear. This study was therefore conducted to investigate the risk factors, person, place and time characteristics, associated with the hepatitis E virus (HEV) epidemic in Napak district.

METHODS

Review of line lists data for epidemiological description and matched case control study on neighborhood and age in the ratio of 1:2 were used to assess risk factors for HEV outbreak in Napak. Cluster and random sampling were used to obtain a sample size of 332, (111 cases, 221 controls). Possible interaction and confounding was assessed using conditional logistic regression.

RESULTS

Over 1359 cases and 30 deaths were reported during 2013/2014 HEV outbreak. The mean age of patients was 29 ± years, 57.9% of cases were females. Overall case Fatality Ratio was 2.2% in general population but 65.2% in pregnant women. More than 94% of the cases were reported in the sub counties of Napak, 5.7% of cases were reported in the outside neighboring districts. The epidemic peaked in January 2014 and gradually subsided by December 2014. Risk factors found to be associated with HEV included drinking untreated water (OR 6.69, 95% CI 3.15-14.16), eating roadside food (OR 6.11, 95% CI 2.85-13.09), reported not cleaning utensils (OR 3.24, 95% CI 1.55-1.76), and being a hunter (OR 1.14, 95% CI 1.03-12.66).

CONCLUSION

The results of this study suggest that the virus is transmitted by the feco-oral route through contaminated water. They also suggest that active surveillance and appropriate measures targeting community and routine individual health actions are important to prevent transmission and decrease the deaths.

Pneumococcal Carriage in Children under Five Years in Uganda-Will Present Pneumococcal Conjugate Vaccines Be Appropriate?

BACKGROUND

Pneumonia is the major cause of death in children globally, with more than 900,000 deaths annually in children under five years of age. Streptococcus pneumoniae causes most deaths, most often in the form of community acquired pneumonia. Pneumococcal conjugate vaccines (PCVs) are currently being implemented in many low-income countries. PCVs decrease vaccine-type pneumococcal carriage, a prerequisite for invasive pneumococcal disease, and thereby affects pneumococcal disease and transmission. In Uganda, PCV was launched in 2014, but baseline data is lacking for pneumococcal serotypes in carriage.

OBJECTIVES

To study pneumococcal nasopharyngeal carriage and serotype distribution in children under 5 years of age prior to PCV introduction in Uganda.

METHODS

Three cross-sectional pneumococcal carriage surveys were conducted in 2008, 2009 and 2011, comprising respectively 150, 587 and 1024 randomly selected children aged less than five years from the Iganga/Mayuge Health and Demographic Surveillance Site. The caretakers were interviewed about illness history of the child and 1723 nasopharyngeal specimens were collected. From these, 927 isolates of S. pneumoniae were serotyped.

RESULTS

Overall, the carriage rate of S. pneumoniae was 56% (957/1723). Pneumococcal carriage was associated with illness on the day of the interview (OR = 1.50, p = 0.04). The most common pneumococcal serotypes were in descending order 19F (16%), 23F (9%), 6A (8%), 29 (7%) and 6B (7%). One percent of the strains were non-typeable. The potential serotype coverage rate for PCV10 was 42% and 54% for PCV13.

CONCLUSION

About half of circulating pneumococcal serotypes in carriage in the Ugandan under-five population studied was covered by available PCVs.

The effect of AIDS defining conditions on immunological recovery among patients initiating antiretroviral therapy at Joint Clinical Research Centre, Uganda

Background

Many HIV-infected patients only access health care once they have developed advanced symptomatic disease resulting from AIDS Defining Conditions (ADCs). We carried out a study to establish the effect of ADCs on immunological recovery among patients initiated on antiretroviral therapy (ART).

Methods

A retrospective cohort of 427 HIV-1 patients who were initiated on ART between January 2002 and December 2006 was studied. Data on ADCs was retrieved from Joint Clinical Research Centre (JCRC) data base and backed up by chart reviews. We employed Kaplan-Meier survival curves to estimate median time to 50 CD4 cells/μl from the baseline value to indicate a good immunological recovery process. Cox proportional hazard models were used at multivariate analysis.

Results

The median time to gaining 50 CD4 cells/μl from the baseline value after ART initiation was longer in the ADC (9.3 months) compared to the non-ADC group (6.9 months) (log rank test, p = 0.027). At multivariate analysis after adjusting for age, sex, baseline CD4 count, baseline HIV viral load, total lymphocyte count and adherence level, factors that shortened the median time to immunological recovery after ART initiation were belonging to the non-ADC group (HR = 1.31; 95% CI: 1.03–1.28, p = 0.028), adherence to ART of ≥ 95% (HR = 2.22; 95% CI: 1.57–3.15, p = 0.001) and a total lymphocyte count ≥ 1200 cells/mm³ (HR = 1.84; 95% CI: 1.22–2.78, p = 0.003). A low baseline CD4 count of ≤ 200 cells/μl (HR = 0.52; 95% CI: 0.37–0.77, p = 0.001) was associated with a longer time to immunological recovery. There was no interaction between low CD4 counts and ADC group.

Conclusion

Patients with ADCs take longer to regain their CD4 counts due to the defect in the immune system. This may prolong their risk of morbidity and mortality.

Antimicrobial stewardship: Attitudes and practices of healthcare providers in selected health facilities in Uganda

Though antimicrobial stewardship (AMS) programmes are the cornerstone of Uganda's national action plan (NAP) on antimicrobial resistance, there is limited evidence on AMS attitude and practices among healthcare providers in health facilities in Uganda. We determined healthcare providers' AMS attitudes, practices, and associated factors in selected health facilities in Uganda. We conducted a cross-sectional study among nurses, clinical officers, pharmacy technicians, medical officers, pharmacists, and medical specialists in 32 selected health facilities in Uganda. Data were collected once from each healthcare provider in the period from October 2019 to February 2020. Data were collected using an interview-administered questionnaire. AMS attitude and practice were analysed using descriptive statistics, where scores of AMS attitude and practices for healthcare providers were classified into high, fair, and low using a modified Blooms categorisation. Associations of AMS attitude and practice scores were determined using ordinal logistic regression. This study reported estimates of AMS attitude and practices, and odds ratios with 95% confidence intervals were reported. We adjusted for clustering at the health facility level using clustered robust standard errors. A total of 582 healthcare providers in 32 healthcare facilities were recruited into the study. More than half of the respondents (58%,340/582) had a high AMS attitude. Being a female (aOR: 0.66, 95% CI: 0.47-0.92, P < 0.016), having a bachelor's degree (aOR: 1.81, 95% CI: 1.24-2.63, P < 0.002) or master's (aOR: 2.06, 95% CI: 1.13-3.75, P < 0.018) were significant predictors of high AMS attitude. Most (46%, 261/582) healthcare providers had fair AMS practices. Healthcare providers in the western region's health facilities were less likely to have a high AMS practice (aOR: 0.52, 95% CI 0.34-0.79, P < 0.002). In this study, most healthcare providers in health facilities had a high AMS attitude and fair AMS practice.

Association between oral candidiasis and low CD4+ count among HIV positive patients in Hoima Regional Referral Hospital

BACKGROUND

The aim of this study was to determine the prevalence of Human Immune Virus (HIV) related oral lesions and their association with Cluster of Differentiation 4 (CD4+) count among treatment naïve HIV positive patients.

METHODS

This was a descriptive and analytical cross sectional study. Participants were 346 treatment naïve HIV positive adult patients. These were consecutively recruited from Hoima Regional Referral hospital between March and April 2012. Data collection involved interviews, oral examinations and laboratory analysis.

RESULTS

A total of 168(48.6%) participants had oral lesions. The four commonest lesions were oral candidiasis (24.9%, CI = 20.6-29.7%), melanotic hyperpigmentation (17.3%, CI = 13.7-21.7%), kaposi sarcoma (9.3%, CI = 6.6-12.8%) and Oral Hairy Leukoplakia (OHL) (5.5%, CI = 3.5-8.4%). There was significant association between oral candidiasis and immunosuppression measured as CD4+ less than 350 cells/mm3 (OR = 2.69, CI = 1.608-4.502, p < 0.001). Oral candidiasis was the only oral lesion significantly predictive of immunosuppression (OR = 2.56, CI = 1.52-4.30, p < 0.001) with a Positive Predictive Value (PPV) of 48.2%, Negative Predictive Value (NPV) of 74.3%, 38.1% sensitivity and specificity of 81.4%.

CONCLUSION

Oral candidiasis can be considered as a marker for immunesuppression, making routine oral examinations essential in the management of HIV positive patients.

An assessment of Makerere University College of Health Sciences: optimizing health research capacity to meet Uganda's priorities

Background

Health research is critical to the institutional mission of the Makerere College of Health Sciences (MakCHS). Optimizing the alignment of health research capacity at MakCHS with the health needs and priorities of Uganda, as outlined in the country’s Health Sector Strategic Plan (HSSP), is a deliberate priority, a responsibility, and a significant opportunity for research. To guide this strategic direction, an assessment of MakCHS’s research grants and publication portfolio was conducted.

Methods

A survey of all new and ongoing grants, as well as all publications, between January 2005 and December 2009 was conducted. Research, training, and education grants awarded to MakCHS’ constituent faculties and departments, were looked for through financial records at the college or by contact with funding organizations. Published manuscripts registered with PubMed, that included MakCHS faculty authors, were also analyzed.

Results

A total of 58 active grants were identified, of which 18 had been initiated prior to 2005 and there were an average of about eight new grants per year. Most grants funded basic and applied research, with major focus areas being HIV/AIDS (44%), malaria (19%), maternal and child health (14%), tuberculosis (11%), mental health (3%), and others (8%). MakCHS faculty were identified as Principal Investigators (PIs) in only 22 (38%) active grants. Grant funding details were only available for one third of the active grants at MakCHS. A total of 837 publications were identified, with an average of 167 publications per year, most of which (66%) addressed the country’s priority health areas, and 58% had MakCHS faculty or students as first authors.

Conclusions

The research grants and publications at MakCHS are generally well-aligned with the Ugandan Health Ministry priorities. Greater efforts to establish centralized and efficient grants management procedures are needed. In addition, greater efforts are needed to expand capacity for MakCHS faculty leadership of grants, as well as to continue to expand the contribution of MakCHS faculty to lead research publications.

Factors associated with utilization of insecticide-treated nets in children seeking health care at a Ugandan hospital: perspective of child caregivers

In Uganda malaria causes more morbidity and mortality than any other disease and children below 5 years contribute the biggest percentage of malaria related mortality. Insecticide treated nets (ITNs) are currently one of the most cost effective option for reducing malaria-related morbidity and mortality, however the factors affecting their utilization in Uganda are still not well understood. This study examined the prevalence and factors associated with ITN utilization among children of age 0-12 years seeking health care from a Ugandan hospital using caregiver's reports. A cross sectional design was used to collect data using a semi-structured questionnaire from 418 participants. Binary logistic regression was employed to determine predictors of ITN utilization. Results show that the prevalence of ITN utilization among children seeking health care was 34.2%. ITN utilization was higher among children of age <5 years [37.0, 95% CI 31.81-42.21] as compared to children aged ≥5 years [22.9, 95% CI 13.77-32.01]. Source of mosquito net (OR = 13.53, 95% CI = 6.47-28.27), formal employment by head of household (OR = 6.00, 95% CI = 1.95-18.48), sharing a bed with parent (s) (OR = 2.61, 95% CI = 1.21-5.63) and number of children below 12 years in a household (OR = 0.80, 95% CI = 0.65-0.99), were significant predictors of utilization. ITN utilization among children was below the set national target. The predictors identified by this study reveal opportunities that can be taken advantage of by malaria control programs to achieve the desired rates of utilization and subsequently malaria prevention in children.

Dental age estimation using radiographic assessment of third molar eruption among 10-20-year-old Ugandan population

Aim

This study aimed at establishing the age for third molar eruption among Ugandans aged 10-20 years.

Materials and Methods

This was a cross-sectional study comprising 471 male and 541 female patients attending Mulago Dental Clinic. Patients' orthopantomographs were assessed for third molar eruption as described by Olze et al. Age was summarized using means/SD. Jaw and sex differences were assessed using Student's t-test.

Results

Complete eruption (Stage D) ranged between 13 and 20 years. The mean age at complete eruption for girls and boys was 17.5-18 years and 18.2-18.6 years, respectively. Mean age was statistically significantly (P < 0.05) lower among girls compared to boys for all third molar teeth (#18, #28, #38, and #48). The difference in mean eruption times between girls and boys was -0.62 (95% confidence interval: 0.2-1.0, P = 0.006). At 18 years, 40% or 41% maxillary and 52% or 53% mandibular molars were completely erupted. There were statistically significant differences in eruption between the sexes and jaws for all teeth (P < 0.05).

Conclusions

Given the fact that the percentage of erupted third molars by age 18 was found to be <50% on an average in this Ugandan population, we should reconsider the use of third molar eruption as a definitive tool for age estimation in this population.

Socioeconomic and nutritional factors associated with age of eruption of third molar tooth among Ugandan adolescents

This study aimed to establish the influence of socioeconomic and nutritional factors on the age of eruption of the mandibular third molar among Ugandans aged 10–20 years.

Baseline Xpert MTB/RIF ct values predict sputum conversion during the intensive phase of anti-TB treatment in HIV infected patients in Kampala, Uganda: a retrospective study

Background

In resource-limited settings, sputum smear conversion is used to document treatment response. Many People living with HIV (PLHIV) are smear-negative at baseline. The Xpert MTB/RIF test can indirectly measure bacterial load through cycle threshold (ct) values. This study aimed to determine if baseline Xpert MTB/RIF could predict time to culture negativity in PLHIV with newly diagnosed TB.

Methods

A subset of 138 PLHIV from the ‘SOUTH’ study on outcomes related to TB and antiretroviral drug concentrations were included. Bacterial load was estimated by Mycobacterium Growth Indicator Tubes (MGIT) culture time-to-positivity (TTP) and Lowenstein Jensen (LJ) colony counts. Changes in TTP and colony counts were analyzed with Poisson Generalised Estimating Equations (GEE) and multilevel ordered logistic regression models, respectively, while time to culture negativity analysed with Cox proportional hazard models. ROC curves were used to explore the accuracy of the ct value in predicting culture negativity.

Results

A total of 81 patients (58.7%) were males, median age 34 (IQR 29  – 40) years, median CD4 cell count of 180 (IQR 68  – 345) cells/μL and 77.5% were ART naive. The median baseline ct value was 25.1 (IQR 21.0  – 30.1). A unit Increase in the ct value was associated with a 5% (IRR = 1.05 95% CI 1.04  – 1.06) and 3% (IRR = 1.03 95% CI 1.03  – 1.04) increase in TTP at week 2 and 4 respectively. With LJ culture, a patient’s colony grade was reduced by 0.86 times (0R = 0.86 95% CI 0.74  – 0.97) at week 2 and 0.84 times (OR = 0.84 95% CI 0.79  – 0.95 P = 0.002) at week 4 for every unit increase in the baseline ct value. There was a 3% higher likelihood of earlier conversion to negativity for every unit increase in the ct value. A ct cut point ≥28 best predicted culture negativity at week 4 with a sensitivity of 91. 7% & specificity 53.7% while a cut point ≥23 best predicted culture negativity at week 8.

Conclusion

Baseline Xpert MTB/RIF ct values predict sputum conversion in PLHIV on anti-TB treatment. Surrogate biomarkers for sputum conversion in PLHIV are still a research priority.

Characteristics of antimicrobial stewardship programmes in hospitals of Uganda

While interest in antimicrobial stewardship programmes (ASPs) is growing in most low- and middle-income countries (LMICs), there is a paucity of information on their adoption or implementation in Africa, particularly Uganda. The study assessed the presence and characteristics of ASPs, implemented antimicrobial stewardship (AMS) strategies and the challenges to their implementation in hospitals in Uganda. We conducted a cross-sectional study among heads of infection prevention committees (IPCs) in regional referral hospitals, general hospitals, and private-not-for-profit (PNFP) hospitals from November 2019 to February 2020. An interviewer-administered questionnaire was used to collect data. We analysed data using descriptive statistics. A total of 32 heads of IPCs were enrolled in the study. Of these, eight were from regional referral hospitals, 21 were from general hospitals, and three were from PNFPs. Most heads of IPC were pharmacists (17/32, 53.1%) with a mean age and standard deviation (sd) of 36.1 (±1.1) years. A formal ASP was adopted or implemented in 14 out of the 32 (44%, 95% CI 26-62) studied hospitals. Thirty out of 32 hospitals implemented at least one type of AMS strategy. Sixty-eight percent (22/32) of the hospitals implemented pre-authorisation and approval as their primary AMS core strategy to optimise antibacterial use. The most commonly reported challenges to the implementation of ASP across all 32 hospitals (with or without ASP) were lack of time for the ASP team (29/32, 90.6%) and lack of allocated funding for antimicrobial stewardship team (29/32, 90.6%). In this study, most hospitals in Uganda implemented at least one AMS strategy despite the low implementation of ASPs in hospitals. The ministry of health needs to sensitise and support the establishment of ASP in hospitals across the country.

Factors Associated with Utilisation of Couple HIV Counselling and Testing Among HIV-Positive Adults in Kyoga Fishing Community Uganda, May 2017: Cross Sectional Study

Couple HIV counseling and testing (CHCT) is key in preventing heterosexual HIV transmission and achievement of 90-90-90 UNAIDS treatment targets by 2020. We conducted secondary data analysis to assess utilization of CHCT and associated factors using logistic regression. 58/134 participants (49%) had ever utilized CHCT. Disclosure of individual HIV results to a partner [aOR = 16; 95% CI: (3.6-67)], residence for > 1 < 5 years [aOR = 0.04; 95% CI (0.005-0.33)], and none mobility [aOR = 3.6; 95% CI (1.1-12)] were significantly associated with CHCT. Age modified relationship between CHCT and disclosure (Likelihood-ratio test LR chi2 = 4.2 (p value = 0.041). Disclosure of individual HIV results with a partner and residence for more than 1 year improved utilization of CHCT; mobility reduced the odds of CHCT. Interventions should target prior discussion of individual HIV results among couples and mobile populations to increase CHCT.

Village health team-delivered oral HIV self-testing increases linkage-to-care and antiretroviral-therapy initiation among men in Uganda

Targeted strategies are central to increasing HIV-status awareness and progress on the care cascade among men. We implemented Village-Health-Team (VHT)-delivered HIV self-testing (HIVST) among men in a peri-urban Ugandan district and assessed linkage to confirmatory-testing, antiretroviral-therapy (ART) initiation and HIV-status disclosure following HIVST. We conducted a prospective cohort study from November 2018 to June 2019 and enrolled 1628 men from 30-villages of Mpigi district. VHTs offered each participant one HIVST-kit and a linkage-to-care information leaflet. At baseline, we collected data on demographics, testing history and risk behavior. At one-month, we measured linkage to confirmatory-testing and HIV-status disclosure, and at three months ART-initiation if tested HIV-positive. We used Poisson regression generalized estimating equations to evaluate predictors of confirmatory-testing. We found that 19.8% had never tested for HIV and 43% had not tested in the last 12-months. After receiving HIVST-kits, 98.5% self-reported HIVST-uptake in 10-days, 78.8% obtained facility-based confirmation in 30-days of HIVST with 3.9% tested HIV-positive. Of the positives, 78.8% were newly diagnosed, 88% initiated ART and 57% disclosed their HIV-status to significant others. Confirmatory testing was associated with having a higher level of education and knowing a partner's HIV-status. VHT-delivered HIVST may be effective for boosting testing, ART-initiation and HIV-status disclosure among men.

Measurement error of mean sac diameter and crown-rump length among pregnant women at Mulago hospital, Uganda

Background

Ultrasonography is essential in the prenatal diagnosis and care for the pregnant mothers. However, the measurements obtained often contain a small percentage of unavoidable error that may have serious clinical implications if substantial. We therefore evaluated the level of intra and inter-observer error in measuring mean sac diameter (MSD) and crown-rump length (CRL) in women between 6 and 10 weeks’ gestation at Mulago hospital.

Methods

This was a cross-sectional study conducted from January to March 2016. We enrolled 56 women with an intrauterine single viable embryo. The women were scanned using a transvaginal (TVS) technique by two observers who were blinded of each other’s measurements. Each observer measured the CRL twice and the MSD once for each woman. Intra-class correlation coefficients (ICCs), 95% limits of agreement (LOA) and technical error of measurement (TEM) were used for analysis.

Results

Intra-observer ICCs for CRL measurements were 0.995 and 0.993 while inter-observer ICCs were 0.988 for CRL and 0.955 for MSD measurements. Intra-observer 95% LOA for CRL were ± 2.04 mm and ± 1.66 mm. Inter-observer LOA were ± 2.35 mm for CRL and ± 4.87 mm for MSD. The intra-observer relative TEM for CRL were 4.62% and 3.70% whereas inter-observer relative TEM were 5.88% and 5.93% for CRL and MSD respectively.

Conclusions

Intra- and inter-observer error of CRL and MSD measurements among pregnant women at Mulago hospital were acceptable. This implies that at Mulago hospital, the error in pregnancy dating is within acceptable margins of ±3 days in first trimester, and the CRL and MSD cut offs of ≥7 mm and ≥ 25 mm respectively are fit for diagnosis of miscarriage on TVS. These findings should be extrapolated to the whole country with caution. Sonographers can achieve acceptable and comparable diagnostic accuracy levels of MSD and CLR measurements with proper training and adherence to practice guidelines.

Acceptability of an online peer support group as a strategy to improve antiretroviral therapy adherence among young people in Kampala District, Uganda: qualitative findings

Introduction

Peer support groups may contribute to adherence and play a role in decreasing stigma to antiretroviral therapy (ART) adherence among young people living with HIV (YPLHIV). However, peer support activities usually occur face-to-face in Uganda and elsewhere in Sub-Saharan Africa, and thus have structural limitations and may not be readily available when young people need them. Online peer support has the potential to help YPLHIV access regular psychosocial support without significant effort or cost. We assessed the acceptability of a WhatsApp-based peer support group as a strategy to improve ART adherence among Ugandan YPLHIV.

Methods

We conducted a formative qualitative study in three health facilities in Kampala, Uganda, between July and August 2022. We held four focus group discussions with twenty-six YPLHIV seeking services at the study facilities. We also conducted six key informant interviews with health providers attached to adolescent HIV care clinics. The data was analyzed using thematic analysis guided by the acceptability framework to understand socio-cultural beliefs and perceptions towards utilizing WhatsApp-based peer support groups for HIV care.

Results

Overall, the peer support group on WhatsApp was acceptable for use among YPLHIV. The young people regarded it as convenient because it would save time and would be more cost-effective compared to the transport costs of in-person meetings. Health providers revealed that the WhatsApp peer support group could reduce the stigma associated with community follow-up for non-adhering young people and empower YPLHIV to overcome stigma. Both the young people and health providers suggested that online peer support could provide accessible emotional support, which could improve YPLHIV's psychosocial well-being and enhance adherence to ART. However, participants raised concerns about privacy, the cost of internet bundles, and smartphones, especially for younger adolescents.

Conclusion

Online peer support groups are acceptable to Ugandan YPLHIV and hold promise in enhancing psychosocial support and improving treatment adherence in this sub-population. In implementing online support groups, due consideration should be given to software tools with high privacy standards and zero-rated data use for new apps. Research is needed to evaluate the feasibility and effectiveness of this peer support model in Uganda.

Antimicrobial Stewardship Programmes: Healthcare Providers' Perspectives on Adopted Hospital Policies That Combat Antibacterial Resistance in Selected Health Facilities in Uganda

Background: This study aimed to determine healthcare providers' perspectives on adopted hospital policies that support establishing antimicrobial stewardship programmes (ASPs) in selected health facilities in Uganda. Results: In this study, 63.1% of healthcare providers had a low-level perspective regarding adopting hospital policies to facilitate the establishment of ASPs. The low-perspective was significantly associated with females (aOR: 17.3, 95% CI: 1.28-2.34, p < 0.001), healthcare practitioners aged 50 + years (aOR: 1.92, 95% CI: 1.22-3.01, p = 0.004), individuals in the Obstetrics and Gynaecology department (aOR: 1.73, 95% CI: 1.03-2.90, p < 0.037), and Uganda's Eastern (aOR: 1.47, 95% CI: 1.03-2.09, p = 0.034) and Northern regions (aOR: 2.97, 95% CI: 1.63-5.42, p < 0.001). Methods: We conducted a cross-sectional study where 582 healthcare providers (response rate (76%) were interviewed using a questionnaire to assess their perspectives on hospital policies that support ASP in 32 selected health facilities. We performed ordinal logistic regression on factors associated with adopted policies, and these were reported with odds ratios (ORs) and 95% confidence intervals (CIs). Conclusions: there was a low-level perspective on adopted hospital policies to support ASPs, which were significantly associated with the sex of healthcare providers, departments, age, and region of the country.

High burden of pulmonary tuberculosis and missed opportunity to initiate treatment among children in Kampala, Uganda

Background: There is uncertainty about the actual burden of childhood TB in Uganda, but underestimation is acknowledged. We aimed at determining prevalence, factors associated with PTB among children attending PHC facilities in Kampala. Methods: This was a cross-sectional study of 255 children, with presumed TB, attending six health facilities in Kampala, Uganda, in March 2015. Socio-demographic, clinical, and laboratory data were collected using a questionnaire. TB was diagnosed using “Desk Guide” algorithms. Sputum based on ZN/FM and/or Gene-Xpert. Logistic regression was used to assess associations with outcomes. Results: Overall, prevalence of PTB 13.7 % (2.6 – 24.8). Among HIV-positive, the prevalence of PTB was 41.7%, while among malnourished children, 21.7% and contacts, 89.3%. The factors that influenced PTB included: tobacco smoker at home (OR =1.6, 95 % CI: 1.07 – 6.86), stunting (OR = 2.2, 95 % CI: 1.01 – 4.15). Only 5.3% of the smear-negative TB children and 81.3% of the smear-positive children were initiated on treatment within a month of diagnosis. Conclusion: Clinical TB among children is underdiagnosed and undertreated. There is a need for more sensitive and specific diagnostic tests, need ways to disseminate and promote uptake of standardized clinical algorithms. Also, contact TB tracing should be strengthened so that such cases can be actively detected even at community level. Keywords: Pediatric; pulmonary; tuberculosis.

Perspectives of female sex workers on HIV pre-exposure prophylaxis delivery in Uganda: A qualitative study

Background

HIV pre-exposure prophylaxis (PrEP) is underutilized by cisgender female sex workers (FSW) despite its proven effectiveness. This study aimed to understand the experiences of FSW with PrEP services in Uganda to inform HIV programming for this key population.

Methods

We conducted qualitative interviews with 19 FSW between June and July 2022 at the Most at Risk Populations Initiative clinic, Mulago Hospital, Kampala, to explore experiences with accessing PrEP Indepth interviews explored: (1) descriptions of where and how PrEP was obtained; (2) perspectives on current approaches for accessing PrEP; and (3) individual encounters with PrEP services. Data were analyzed through inductive thematic analysis.

Results

Three key themes emerged for FSW perspectives on PrEP service delivery. FSW highlighted the positive impact of a welcoming clinic environment, which motivated FSW to initiate PrEP and fostered a sense of connectedness within their community. They also reported feeling accepted, secure, and free from prejudice when accessing PrEP through facility-based services. The second explores the obstacles faced by FSW, such as lengthy wait times at clinics, inadequate provider support, and lack of sensitivity training which hindered their access to PrEP The third sheds light on how HIV-related stigma negatively impacted the delivery of community-based PrEP for FSW. While community-based distribution offered convenience and helped mitigate stigma, clinic-based care provided greater anonymity and was perceived as offering higher-quality care. Overall, FSWs emphasized the critical role of friendly healthcare providers, social support, and non-stigmatizing environments in promoting successful utilization of PrEP.

Conclusion

The study findings offer insights that can support HIV programs in optimizing PrEP delivery for FSW. Establishing easily accessible drug pick-up locations, prioritizing privacy, addressing and improving health workers' attitudes, and providing regular reminders could enhance PrEP access for FSW and decrease HIV acquisition.

Level of and factors associated with optimal uptake of intermittent preventive treatment for malaria in pregnancy at private-not-for-profit health facilities in Kasese district

Malaria in pregnancy poses a high risk of poor maternal and neonatal outcomes and WHO recommends IPTp. However, its uptake has remained sub-optimal among mothers who attend antenatal care at private-not-for-profit health facilities. This study determined the level of and factors associated with uptake Intermittent preventive treatment of malaria for pregnant women (IPTp) at private-not-for-profit (PNFP) health facilities in Kasese District, Uganda. This was a cross-sectional study involving 396 postpartum mothers in the postnatal wards of 8 PNFP health facilities in Kasese district was conducted in September 2022. One hospital and 2 Health Centre IVs were purposively selected and 5 Health Centre IIIs selected randomly. Mothers were consecutively selected and interviewer administered semi-structured questionnaires were used to collect the data. Data were entered in epi-data version 3.1, cleaned and analyzed using STATA version 14. Data were adjusted for clustering & modified poison regression was used to determine associations of the factors and the outcome. From the analysis, level of optimal uptake of IPTp was 51.5% CI = (46.6-56.4). Being married (aPR = 1.35, 95% CI = 1.06-1.7, p = 0.014), attending ANC more than 4 Visits (aPR = 1.29, 95%CI = 1.09-1.54, p<0.001) positively influence optimal uptake while not taking IPTp at recommended time intervals (aPR = 0.49, 95%CI = 0.39-0.62 p<0.001) and mothers paying for IPTp drugs themselves (aPR = 0.74, 95%CI = 0.57-0.97, p = 0.031) negatively influence optimal uptake. This moderate uptake of IPTp among pregnant mothers suggests insufficient protection of pregnant mothers against malaria. Efforts to improve Antenatal care attendance, taking IPTp at recommended time intervals, not paying for ITPp drugs and encouraging marriages should be intensified.

Acceptability of an online peer support group as a strategy to improve antiretroviral therapy adherence among young people in Kampala district, Uganda: qualitative findings

INTRODUCTION

Peer support groups may contribute to adherence and play a role in decreasing the stigma of antiretroviral therapy (ART) adherence among young people living with HIV (YPLHIV). However, peer support activities usually occur face-to-face in Uganda and elsewhere in Sub-Saharan Africa and thus have structural limitations and may not be readily available when young people need them. Online peer support has the potential to help YPLHIV access regular psychosocial support without significant effort or cost. We assessed the acceptability of a WhatsApp peer support group as a strategy to improve ART adherence among Ugandan YPLHIV.

METHODS

We conducted a formative qualitative study in three health facilities in Kampala, Uganda, between July and August 2022. We held four focus group discussions with twenty-six YPLHIV seeking services at the study facilities. We also conducted six key informant interviews with health providers attached to adolescent HIV care clinics. Data was analyzed using thematic analysis guided by Sekhon's theoretical framework of acceptability (2017), which conceptualizes acceptability through multiple constructs, including affective attitudes, burden, intervention coherence, and perceived effectiveness. Our analysis examined these dimensions in the context of WhatsApp-based peer support groups for HIV care.

RESULTS

Overall, WhatsApp peer support groups were acceptable for use among YPLHIV. The young people regarded it as convenient because it would save time and would be more cost-effective compared to the transport costs of in-person meetings. Health providers revealed that the WhatsApp peer support group could reduce the stigma associated with community follow-up and empower YPLHIV to overcome stigma. Both young people and health providers suggested that online peer support could enhance emotional support, psychosocial well-being, and ART adherence. However, participants raised concerns about privacy and the cost of internet bundles and smartphones, especially for younger adolescents.

CONCLUSION

Online peer support groups are acceptable to Ugandan YPLHIV and hold promise in enhancing psychosocial support and improving treatment adherence in this sub-population. In implementing online support groups, due consideration should be given to software tools with high privacy standards and zero-rated data use for new apps. Research is needed to evaluate the feasibility and effectiveness of this peer support model in Uganda.

The role of medicines and therapeutics committees structure in supporting optimal antibacterial use in hospitals in Uganda: A mixed method study

Although the roles of Medicines and therapeutic committees (MTCs) have been expanding, there is limited information on the role of their structure in optimal antibacterial use in hospitals, especially in low-and-middle-income countries. Our study explored the structure and role of MTC in supporting antibacterial use in regional referral, general hospitals and tertiary private not-for-profit (PNFP) hospitals in Uganda. We conducted an explanatory sequential mixed-method approach with triangulation to explore the structure and functional role of MTCs from August 2019 to February 2020 in hospitals in Uganda. Quantitative data was collected using an interviewer-administered questionnaire among chairpersons or secretaries of MTCs and was analysed using descriptive statistics. We conducted key informant interviews using an interview guide among long-term serving members of MTCs to collect qualitative data which triangulated the quantitative data. The study revealed that sixteen hospitals had successfully established MTCs with an average duration of the MTCs' existence of 5.6 (+2.7) years. The membership of the MTCs varied between 7 and 14, with a median value of 10, and the majority of members in MTCs were pharmacists (15 out of 16) and clinical specialists (13 out of 16). The most frequent subcommittees of the 16 hospitals MTC were supply chain (n = 14), antimicrobial stewardship (n = 13), and infection control (n = 12). Majority (14 out of 16) of the MTCs supported availability and access of antibacterial use by selecting and evaluating antibacterials agents for their formulary lists using established criteria. Additionally, 15 out 16 MTCs conducted antimicrobial stewardship activities to support optimal antimicrobial use. In our study, MTC membership and subcommittees were critical structural components that aided the selection and evaluation antibacterials on hospital formulary lists and they supported optimal antibacterial use through implementing various antimicrobial stewardship activities. There is a need for the Ministry of Health to conduct more training on operationalising MTCs structures in all hospitals.

Unmasking the Ethical Dimensions of Data-sharing in Health Research: Perspectives from Researchers at a Public University in Uganda

Background

In resource-limited settings like Uganda, ethical sharing of health research data is crucial for advancing scientific knowledge. Despite the growing trend of data sharing in the digital age, its adoption in low-resource contexts is often hampered by complex ethical considerations. This report investigates these ethical concerns using data from researchers at a public university, with the goal of informing the development of practical solutions to promote ethical data-sharing practices in Uganda.

Methods

A qualitative phenomenographic study was conducted with 26 participants at Makerere University College of Health Sciences, including professors, lecturers, research fellows, and PhD students. In-depth interviews were conducted via Zoom or in person, using an interview guide. Data were analyzed thematically using ATLAS.ti (V9), following both deductive and inductive approaches.

Results

The study revealed a complex landscape of data-sharing practices among researchers. Participants had varying understandings of data sharing, with some expressing limited awareness. Incentives were widely recognized as crucial for encouraging data sharing. While acknowledging data sources in publications was appreciated, some researchers advocated for co-authorship for significant contributions. Researchers' autonomy and control over data-sharing practices were influenced by factors such as research concept origination, funding sources, researchers' financial status, and analytical skills. Institutional policies, cultural norms, and customs that promote a 'siloed' research environment also significantly influenced of data-sharing behavior.

Conclusion

This study revealed a complex landscape of data-sharing practices among researchers. The varying interpretations of data sharing highlight the need for enhanced education and awareness regarding its importance. The identified incentives, such as financial rewards and co-authorship, which encourage data sharing, suggest a need to establish a fair data-sharing reward system. Additionally, policies that facilitate researchers' autonomy and data control, while fostering trust, are crucial to address the siloed research culture.

Loss to follow up after pregnancy among mothers enrolled on the option B+ program in Uganda

Objective

Option-B+ programs in Uganda have reported high levels of loss to follow up (LTFU) after cessation of breastfeeding, and this remains unknown beyond this period. In this study, we assessed the incidence and factors associated with LTFU two to four years after delivery among Option-B+ mothers.

Study design

Retrospective cohort.

Methods

We reviewed files of 452 mothers who enrolled on Option-B+ between January 1st, 2013 and December 31st, 2014 ​at Kisenyi Health Centre IV in Kampala district. We assessed factors associated with LTFU using Cox proportional hazards regression. We also explored the reasons for LTFU using three focus group discussions, five in-depth and three key informant interviews.

Results

Of the 452 mothers, 131(29%) were LTFU after delivery. The incidence of LTFU after delivery was 17/1000 person months (95% CI, 14–30/1000) with a median follow up of 32 months. The risk of LTFU was higher among mothers who started ART on the day they tested HIV positive (aHR ​= ​1.66, 95% CI; 1.25–2.20, p-value< 0.001). Reasons for LFTU included transport costs, stigma, poor human resource policies and non-disclosure.

Conclusion

LTFU after delivery among Option-B+ mothers is higher than the global target of 15%. ART initiation on the day a mother tests positive increases the risk of LTFU. The major reasons for LTFU were stigma and non-disclosure. To reduce the risk of LTFU, we recommend approaches that encourage disclosure to sexual partners and ongoing specific support to mothers who are initiated on ART-the day of positive test.

•

Loss to follow up (LTFU) among Option-B+ mothers after delivery is high.

•

ART initiation on the day a mother tests positive increases the risk of LTFU.

•

Non-disclosure is a major contributor to LTFU among Option-B+ mothers.
