Oral PrEP continuation rates among key populations in Nigeria
INTRODUCTION: Pre-exposure prophylaxis (PrEP) is an effective HIV prevention strategy, but its impact is limited by low uptake and poor continuation rates. This study investigates oral PrEP continuation among key populations (KPs) enrolled in an HIV prevention programme across seven states in Nigeria, representing one of the largest longitudinal PrEP continuation studies in Sub-Saharan Africa to date. METHODS: We analysed data from 43 788 clients…
The case for investing in provider-administered subcutaneous DMPA
INTRODUCTION: Depot medroxyprogesterone acetate (DMPA) is available as provider-administered intramuscular (DMPA-IM) and subcutaneous injections (PA DMPA-SC), as well as DMPA-SC self-injection (SI), which enhances accessibility and continuation by reducing facility visits. However, DMPA-SC has a higher unit price than DMPA-IM, and low SI uptake can undermine its cost-effectiveness. This study assessed whether PA DMPA-SC's potential benefits justi…
Factors associated with self-reported diagnosis of depression in Kenya
The proportion of participants who self-reported depression was low. Besides, there was a considerable variation in self-reported depression across different counties in Kenya. Furthermore, there was variability in depression among different socio-demographic groups. Therefore, there is a need to target mental health interventions to persons with chronic conditions and those in middle economic class as they are greatly affected with depression
Prevalence and factors associated with HIV drug resistance among adult persons living with HIV/Aids in nine countries of Sub-Saharan Africa using population-based HIV impact assessments
This study concludes by highlighting the substantial prevalence of HIVDR in SSA, which varies significantly among nations and sociodemographic characteristics. The results highlight the importance of ART use and viral load suppression in determining HIVDR prevalence, underscoring the necessity of focused interventions to enhance viral load monitoring and ART adherence. To combat the growing threat of HIVDR and guarantee the long-term efficacy of …
Uptake of Covid-19 vaccine and associated factors among Health Care Workers at Queen Elizabeth Central Hospital in Malawi
Globally, the introduction of the Coronavirus Disease of 2019 (COVID-19) vaccine within one year of the pandemic brought doubts to the general population including health professionals. Even though Health Care Workers (HCWs) are at a high risk of contracting and transmitting the coronavirus due to their work, their COVID-19 vaccine uptake is unknown. This study aimed to determine the uptake of the COVID-19 vaccine and identify factors associated …
Covid-19 vaccine inequity in African low-income countries
Equitable access and utilization of the COVID-19 vaccine is the main exit strategy from the pandemic. This paper used proceedings from the Second Extraordinary Think-Tank conference, which was held by the Health Economics and Policy Unit at the Kamuzu University of Health Sciences in collaboration with the Malawi Ministry of Health, complemented by a review of literature. We found disparities in COVID-19 vaccine coverage among low-income countrie…
Quality of life among type 2 diabetes mellitus patients at Kamuzu Central Hospital in Lilongwe, Malawi
Type II diabetes mellitus (T2DM) significantly impacts quality of life (QoL) yet data among these patients in Malawi are lacking. This study was conducted to assess QoL among patients with T2DM. A mixed-method cross-section study was conducted at Kamuzu Central Hospital (KCH), Lilongwe, Malawi. Data collection was done using a modified diabetes quality of life (MDQoL)-17 questionnaire for quantitative data while in-depth interviews and diary meth…
Modeling Contraception and Pregnancy in Malawi
Malawi has high unmet need for contraception with a costed national plan to increase contraception use. Estimating how such investments might impact future population size in Malawi can help policymakers understand effects and value of policies to increase contraception uptake. We developed a new model of contraception and pregnancy using individual‐level data capturing complexities of contraception initiation, switching, discontinuation, and fai…
Leveraging human resources for outbreak analysis
Emerging infectious diseases are a growing threat in sub-Saharan African countries, but the human and technical capacity to quickly respond to outbreaks remains limited. Here, we describe the experience and lessons learned from a joint project with the WHO Regional Office for Africa (WHO AFRO) to support the sub-Saharan African COVID-19 response.In June 2020, WHO AFRO contracted a number of consultants to reinforce the COVID-19 response in member…
Retention in care under universal antiretroviral therapy for HIV-infected pregnant and breastfeeding women (‘Option B+’) in Malawi
OBJECTIVE: To explore the levels and determinants of loss to follow-up (LTF) under universal lifelong antiretroviral therapy (ART) for pregnant and breastfeeding women ('Option B+') in Malawi. DESIGN, SETTING, AND PARTICIPANTS: We examined retention in care, from the date of ART initiation up to 6 months, for women in the Option B+ program. We analysed nationwide facility-level data on women who started ART at 540 facilities (n = 21,939), as well…
Timing of antiretroviral therapy and regimen for HIV-infected patients with tuberculosis
Implementation of the 2011 Malawi Integrated ART/PMTCT guidelines was associated with an overall increase in ART uptake among TB/HIV patients and with an increase in the number of patients initiating ART within two weeks of starting their TB treatment. However, the reduction in time between initiating TB treatment and starting ART was small suggesting that further measures must be implemented to facilitate ART uptake. Early enrolment in HIV care …
