  • Implementation strategies to increase Malawian health care workers’ knowledge about and self-efficacy to recommend HPV vaccination

    Open AccessCorrina Moucheraud, Sam Phiri et al.ARTICLEPLOS Global Public Health2026

    Health workers’ recommendation of HPV vaccination is a highly effective evidence-based intervention for increasing the uptake of this important cancer prevention tool. In Malawi, as in many countries, HPV vaccine uptake is low. In preparation for an implementation science study using an intervention optimization design, we pilot tested two implementation strategies aimed at increasing Malawian health workers’knowledge and self-efficacy to counsel…

  • Access to HIV treatment during community-wide flooding

    Open AccessMisheck Mphande, R Paneno et al.ARTICLEPLOS Global Public Health2026

    Community-wide flooding in high HIV-burdened districts affects continuity of HIV care, especially in resource-limited countries in sub-Saharan Africa. We explored the lived experiences of antiretroviral therapy (ART) clients and health care workers (HCWs) in Malawi to understand challenges and potential solutions for ART delivery during floods. This was a mixed methods study. In quantitative analysis, we used routine program data from Partners in…

  • Barriers to viral suppression in children aged 9 years or younger on dolutegravir-based antiretroviral therapy in Malawi, a mixed-methods study

    Open AccessKhumbo Phiri, Christine Hagstrom et al.ARTICLEPLOS Global Public Health2025

    After the transition to pediatric dolutegravir-based regimens, viral load (VL) suppression among children with HIV (CWH) in Malawi has remained suboptimal. This mixed-methods study assessed factors associated with high VL among young CWH on dolutegravir-based antiretroviral therapy (ART) and explored adherence barriers from primary-caregiver and healthcare worker perspectives. Between April-July 2023, we performed an unmatched case-control study …

  • Health care needs survey to improve preparedness of community outreach clinics after severe flooding in Mulanje district, Malawi

    Open AccessJoseph Njala, Kelvin Balakasi et al.ARTICLEPLOS Global Public Health2025

    Due to the rising impact of climate change, Malawi has increasingly experienced extreme weather events in the last decade, including flooding that resulted in large-scale displacement of vulnerable populations. In response, the Ministry of Health and partners set up outreach clinics at camps for displaced persons. However, little is known about health care needs of the affected populations. We conducted a cross-sectional survey among individuals …

  • Intimate partner violence among HIV index case testing clients in Malawi, a mixed-methods study

    Open AccessMaria Sanena, Christine Hagstrom et al.ARTICLEPLOS Global Public Health2025

    While its prevalence in sub-Saharan Africa is high, intimate partner violence (IPV) is rarely reported during routine index case testing (ICT) services in Malawi. We retrospectively explored the occurrence of IPV in a large, PEPFAR-supported HIV care and treatment program, among people with HIV (PWH) who had previously accessed ICT services. Between July-August 2022, we enrolled PWH aged ≥18 years, at 15 health facilities, who had received ICT se…

  • Healthcare provider and health system leader perspectives on barriers to hypertension care in Malawi

    Open AccessChristine Hagstrom, Pericles Kalande et al.ARTICLEGlobal Health Action2025

    BACKGROUND: Malawi has a significant burden of hypertension, including for people with HIV. The World Health Organization recommends integrated HIV-hypertension care, but such integration is not widely implemented in resource-constrained settings. OBJECTIVE: This study explored barriers to hypertension care in Malawi from the perspectives of healthcare providers and health system leaders. METHODS: We conducted a qualitative study of providers and…

  • Preferences for Hypertension Care in Malawi

    Open AccessRisa M Hoffman, Khumbo Phiri et al.ARTICLEAIDS and Behavior2024

    Hypertension is the most common non-communicable disease diagnosed among people in sub-Saharan Africa. However, little is known about client preferences for hypertension care. We performed a discrete choice experiment in Malawi among people with hypertension, with and without HIV. Participants were asked to select between two care scenarios, each with six attributes: distance, waiting time, provider friendliness, individual or group care, antihyp…

  • Men’s Satisfaction with General Health Services is Associated with Future Use of HIV Testing in Malawi

    Open AccessMarguerite Thorp, Kelvin Balakasi et al.ARTICLEAIDS and Behavior2024

    Across sub-Saharan Africa, men are less likely to know their HIV status than women, leading to later treatment initiation. Little is known about how experiences with general health services affect men's use of HIV testing. We used data from a 2019 community-representative survey of men in Malawi to understand frequency and cause of men's negative health service experiences (defined as men reporting they "would not recommend" a facility) and their…

  • Burnout and depression

    Open AccessKhumbo Phiri, John Songo et al.ARTICLEPLOS Global Public Health2023

    Health care workers (HCWs) in eastern Africa experience high levels of burnout and depression, and this may be exacerbated during the COVID-19 pandemic due to anxiety and increased work pressure. We assessed the prevalence of burnout, depression and associated factors among Malawian HCWs who provided HIV care during the COVID-19 pandemic. From April-May 2021, between the second and third COVID-19 waves in Malawi, we randomly selected HCWs from 32…

  • Provider-led community antiretroviral therapy distribution in Malawi

    Open AccessJohn Songo, Hannah Whitehead et al.ARTICLEPLOS Global Public Health2023

    Background Outcomes of community antiretroviral therapy (ART) distribution (CAD), in which provider–led ART teams deliver integrated HIV services at health posts in communities, have been mixed in sub-Saharan African countries. CAD outcomes and costs relative to facility-based care have not been reported from Malawi. Methods We performed a retrospective cohort study in two Malawian districts (Lilongwe and Chikwawa districts), comparing CAD with f…

  • Prisoners’ access to HIV services in southern Malawi

    Open AccessAustrida Gondwe, Alemayehu Amberbir et al.ARTICLEBMC Public Health2021

    Malawian prisoners reported adequate knowledge about HIV services albeit with gaps in specific areas. Prisoners from smaller, rural prisons had suboptimal access to comprehensive HIV services and female prisoners reported having less access to health care than males. Prisoners have great concern about their poor living conditions affecting general health and adherence to ART. These findings provide guidance for improvement of HIV services and gen…

  • The burden of hypertension, diabetes mellitus, and cardiovascular risk factors among adult Malawians in HIV care

    Open AccessOscar Divala, Oscar H Divala et al.ARTICLEBMC Public Health2016

    Among patients in HIV care 26.6% had hypertension and/or diabetes. Close to two-thirds of hypertension diagnoses was stage I and of those few had an indication for antihypertensive pharmacotherapy. According to our criteria, 13.0% of HIV patients in care required drug treatment for hypertension and/or diabetes

  • Characteristics and outcomes of women initiating ART during pregnancy versus breastfeeding in Option B+ in Malawi

    Open AccessMegan Landes, S Sodhi et al.ARTICLEBMC Public Health2016

    Many women in Malawi started ART during breastfeeding within Option B+ and were older and had more advanced WHO Clinical Staging. This represents a missed PMTCT opportunity to initiate treatment early in pregnancy. Early defaulting is identified as a challenge within Option B+, and was more likely among younger women and those initiating ART in pregnancy. Targeted research to understand factors associated with uptake of ART during pregnancy and r…

  • Retention in care under universal antiretroviral therapy for HIV-infected pregnant and breastfeeding women (‘Option B+’) in Malawi

    Lyson Tenthani, Andreas D Haas et al.ARTICLEAIDS2014

    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…

  • Evidence of improving antiretroviral therapy treatment delays

    Open AccessDerek J Sloan, Joep J van Oosterhout et al.ARTICLEBMC Public Health2013

    Continued improvements in treatment delays provide evidence that universal access to ART can be achieved using the public health approach adopted by Malawi However, the longer delays for women and patients diagnosed at outlying sites emphasises the need for targeted interventions to support equitable access for these groups

  • HIV testing coverage of family members of adult antiretroviral therapy patients in Malawi

    Danielle Cohen, M Lungu et al.ARTICLEAIDS Care2010

    Many children in sub-Saharan Africa die from AIDS, not having accessed HIV testing and care. Children of adult antiretroviral therapy (ART) patients are a target group for HIV testing in order to increase access to care, but the HIV test coverage of this group in Malawi is unknown. In a cross-sectional survey of 832 patients at a large urban ART clinic in Blantyre, we found that 81.2% of 1223 children and 37.7% of 488 spouses of adult ART patient…

  • The benefit of supplementary feeding for wasted Malawian adults initiating ART

    Joep J van Oosterhout, Macdonald Ndekha et al.ARTICLEAIDS Care2010

    Food insecurity is considered to be an important contributor to HIV associated wasting in sub-Saharan Africa. Low body mass index (BMI) is a strong risk factor for early mortality during antiretroviral therapy (ART). Nutritional supplementation has become standard of care in wasted patients starting ART in many countries in the region, but there is no unequivocal evidence base for this intervention. Against this background, we performed a retrosp…
