Background Studies of Malawi’s Option B+ programme for HIV-positive pregnant and breastfeeding women have reported high loss to follow-up during pregnancy and at the start of antiretroviral therapy (ART), but few data exist about retention during breastfeeding and after weaning. We examined loss to follow-up and retention in care in patients in the Option B+ programme during their first 3 years on ART. Methods We analysed two data sources: aggregated facility-level data about patients in Option B+ who started ART between Oct 1, 2011, and June 30, 2012, at 546 health facilities; and patient-level data from 20 large facilities with electronic medical record system for HIV-positive women who started ART between Sept 1, 2011, and Dec 31, 2013, under Option B+ or because they had WHO clinical stages 3 or 4 disease or had CD4 counts of less than 350 cells per μL. We used facility-level data to calculate representative estimates of retention and loss to follow-up. We used patient- level data to study temporal trends in retention, timing of loss to follow-up, and predictors of no follow-up and loss to follow-up. We defined patients who were more than 60 days late for their first follow-up visit as having no follow-up and patients who were more than 60 days late for a subsequent visit as being lost to follow-up. We calculated proportions and cumulative probabilities of patients who had died, stopped ART, had no follow-up, were lost to follow-up, or were retained alive on ART for 36 months. We calculated odds ratios and hazard ratios to examine predictors of no follow-up and loss to follow-up. Findings Analysis of facility-level data about patients in Option B+ who had not transferred to a different facility showed retention in care to be 76·8% (20 475 of 26 658 patients) after 12 months, 70·8% (18 306 of 25 849 patients) after 24 months, and 69·7% (17 787 of 25 535 patients) after 36 months. Patient-level data included 29 145 patients. 14 630 (50·2%) began treatment under Option B+. Patients in Option B+ had a higher risk of having no follow-up and, for the first 2 years of ART, higher risk of loss to follow-up than did patients who started ART because they had CD4 counts less than 350 cells per μL or WHO clinical stage 3 or 4 disease. Risk of loss to follow-up during the third year was low and similar for patients retained for 2 years. Retention rates did not change as the Option B+ programme matured. Interpretation Our data suggest that pregnant and breastfeeding women who start ART immediately after they are diagnosed with HIV can be retained on ART through the Option B+ programme, even after many have stopped breastfeeding. Interventions might be needed to improve retention in the first year on ART in Option B+.

One-third of women enrolled in Malawi's program to prevent human immunodeficiency virus mother-to-child-transmission (Option B+) adhered inadequately to antiretroviral therapy during pregnancy and breastfeeding. Long-term virological outcomes must be closely monitored, and effective interventions to improve adherence should be deployed.

Introduction: In Malawi, HIV-infected pregnant and breastfeeding women are offered lifelong antiretroviral therapy (ART) regardless of CD4 count or clinical stage (Option B+). Their HIV-exposed children are enrolled in the national prevention of mother-to-child transmission (PMTCT) programme, but many are lost to follow-up. We estimated the cumulative incidence of vertical HIV transmission, taking loss to follow-up into account. Methods: We abstracted data from HIV-exposed children enrolled into care between September 2011 and June 2014 from patient records at 21 health facilities in central and southern Malawi. We used competing risk models to estimate the probability of loss to follow-up, death, ART initiation and discharge, and used pooled logistic regression and inverse probability of censoring weighting to estimate the vertical HIV transmission risk. Results: A total of 11,285 children were included; 9285 (82%) were born to women who initiated ART during pregnancy. At age 30 months, an estimated 57.9% (95% CI 56.6–59.2) of children were lost to follow-up, 0.8% (0.6–1.0) had died, 2.6% (2.3–3.0) initiated ART, 36.5% (35.2–37.9) were discharged HIV-negative and 2.2% (1.5–2.8) continued follow-up. We estimated that 5.3% (95% CI 4.7–5.9) of the children who enrolled were HIV-infected by the age of 30 months, but only about half of these children (2.6%; 95% CI 2.3–2.9) were diagnosed. Conclusions: Confirmed mother-to-child transmission rates were low, but due to poor retention only about half of HIV-infected children were diagnosed. Tracing of children lost to follow-up and HIV testing in outpatient clinics should be scaled up to ensure that all HIV-positive children have access to early ART.

Rationale-The Global Burden of Disease Study suggests almost 3.5 million people die as a consequence of household air pollution every year. Respiratory diseases including chronic obstructive pulmonary disease and pneumonia in children are strongly associated with exposure to household air pollution. Smoke from burning biomass fuels for cooking, heating, and lighting is the main contributor to high household air pollution levels in low-income countries like Malawi. A greater understanding of biomass fuel use in Malawi should enable us to address household air pollution-associated communicable and noncommunicable diseases more effectively.Objectives-To conduct a cross-sectional analysis of biomass fuel use and population demographics among adults in Blantyre, Malawi.Methods-We used global positioning system-enabled personal digital assistants to collect data on location, age, sex, marital status, education, occupation, and fuel use. We describe these data and explore associations between demographics and reported fuel type. Measurements and MainResults-A total of 16,079 adults participated (nine households refused); median age was 30 years, there was a similar distribution of men and women, 60% were married, and 62% received secondary school education. The most commonly reported occupation for men and women was "salaried employment" (40.7%) and "petty trader and marketing" (23.5%), respectively. Charcoal (81.5% of households), wood (36.5%), and electricity (29.1%) were the main fuels used at home. Only 3.9% of households used electricity exclusively. Lower educational and occupational attainment was associated with greater use of wood.Correspondence and requests for reprints should be addressed to Kevin Mortimer, M.A., M.B., B.Chir., M.Sc., Ph.D., Liverpool School of Tropical Medicine, Pembroke Place, Liverpool L3 5QA, UK.

Conclusions-This large cross-sectional study has identified extensive use of biomass fuels in a typical sub-Saharan Africa periurban population in which women and people of lower socioeconomic status are disproportionately affected. Biomass fuel use is likely to be a major driver of existing communicable respiratory disease and the emerging noncommunicable disease (especially respiratory and cardiovascular) epidemic in this region. Our data will help inform the rationale for specific intervention studies and the development of appropriately targeted public health strategies to tackle this important and poverty-related global health problem.

BackgroundMortality from acute bacterial meningitis (ABM) in sub-Saharan African adults and adolescents exceeds 50%. We tested if Goal Directed Therapy (GDT) was feasible for adults and adolescents with clinically suspected ABM in Malawi.Materials and methodsSequential patient cohorts of adults and adolescents with clinically suspected ABM were recruited in the emergency department of a teaching hospital in Malawi using a before/after design. Routine care was monitored in year one (P1). In year two (P2), nurses delivered protocolised GDT (rapid antibiotics, airway support, oxygenation, seizure control and fluid resuscitation) to a second cohort. The primary endpoint was composite mean number of clinical goals attained. Secondary endpoints were individual goals attained and death or disability from proven or probable ABM at day 40.Results563 patients with suspected ABM were enrolled in the study; 273 were monitored in P1; 290 patients with suspected ABM received GDT in P2. 61% were male, median age 33 years and 90% were HIV co-infected. ABM was proven or probable in 132 (23%) patients. GDT attained more clinical goals compared to routine care: composite mean number of goals in P1 was 0·55 vs. 1·57 in P2 GDT (p<0·001); Death or disability by day 40 from proven or probable ABM occurred in 29/57 (51%) in P1 and 38/60 (63%) in P2 (p = 0·19).ConclusionNurse-led GDT in a resource-constrained setting was associated with improved delivery of protocolised care. Outcome was unaffected.Trial registrationwww.isrctn.com ISRCTN96218197

Most Malawian women who start ART under Option B+ are still in care three years later, a higher than average adherence rate for life-threatening chronic disease treatments, worldwide (50%). We asked 75 Malawian on ART their motivations for remaining in treatment, and what barriers they overcame. Focus groups and interviews included 75 women on ART for 6+ months, at 12 health facilities. Four main motivations for continuing ART emerged: 1) evidence that ART improved their own and their children’s health; 2) strong desire to be healthy and keep their children healthy; 3) treatment was socially supported; 4) HIV/ART counselling effectively showed benefits of ART and told women what to expect. Women surmounted the following barriers: 1) stigma; 2) health care system; 3) economic; 4) side effects. Women stayed on ART because they believed it works. Future interventions should focus on emphasizing ART’s effectiveness, along with other services they provide.

Malawi’s Option B+ program is based on a ‘test and treat’ strategy that places all HIV-positive pregnant and lactating women on lifelong antiretroviral therapy. The steep increase in patient load placed severe pressure on a health system that has struggled for decades with inadequate supply of health care workers (HCWs) and poor infrastructure. We set out to explore health system barriers to Option B+ by asking HCWs in Malawi about their experiences treating pregnant and lactating women. We observed and conducted semi-structured interviews (SSIs) with 34 HCWs including nine expert clients (ECs) at 14 health facilities across Malawi, then coded and analyzed the data. We found that HCWs implementing Option B+ are so overburdened in Malawi that it reduces their ability to provide quality care to patients, who receive less counseling than they should, wait longer than is reasonable, and have very little privacy. Interventions that increase the number of HCWs and upgrade infrastructure to protect the privacy of HIV-infected pregnant and lactating women and their husbands could increase retention, but facilities will need to be improved to support men who accompany their partners on clinic visits.
