Introduction: Zambia is one of the few countries in Africa to permit termination of pregnancy (TOP) on a wide range of grounds. However, substantial barriers remain to TOP and postabortion care (PAC). Methods: We conducted a census of 153 facilities between March and May 2016. We defined facilities according to whether they met basic and/or comprehensive signal functions criteria for TOP and PAC. We linked our facility data to census data to estimate geographic accessibility under different policy scenarios. Results: Overall, 16% of facilities reported they had performed a TOP and 39% performed a PAC in the last year. Facilities were twice as likely to use medical methods for TOP compared with surgical methods, and four times more likely for PAC. Considerably more facilities had performed TOP or PAC than met the basic or comprehensive signal functions criteria, indicating services were being performed in facilities below essential quality standards. Under current Zambian law for non-emergency scenarios, 21% of women in Central Province lived within 15 km of a facility with basic capability to provide TOP; if midlevel providers were trained to provide TOP, this would increase to 36%. Conclusion: A supportive legislative framework is essential, but not in itself sufficient, for adequate access to services. Training midlevel providers, in line with WHO guidance, and ensuring equipment is available in primary care can increase accessibility of TOP and PAC. While both medical and surgical methods need to be available, medical abortion is a safe and effective method that can be provided in low-resource settings.

BackgroundWith the accessibility of prevention of mother to child transmission (PMTCT) services in sub‐Saharan Africa, more women are being tested for HIV in antenatal care settings. Involving partners in the counselling and testing process could help prevent horizontal and vertical transmission of HIV. This study was conducted to assess the feasibility of couples' voluntary counseling and testing (CVCT) in antenatal care and to measure compliance with PMTCT.MethodsA prospective cohort study was conducted over eight months at two public antenatal clinics in Kigali, Rwanda, and Lusaka, Zambia. A convenience sample of 3625 pregnant women was enrolled. Of these, 1054 women were lost to follow up. The intervention consisted of same‐day individual voluntary counselling and testing (VCT) and weekend CVCT; HIV‐positive participants received nevirapine tablets. In Kigali, nevirapine syrup was provided in the labour and delivery ward; in Lusaka, nevirapine syrup was supplied in pre‐measured single‐dose syringes. The main outcome measures were nurse midwife‐recorded deliveries and reported nevirapine use.ResultsIn eight months, 1940 women enrolled in Kigali (984 VCT, 956 CVCT) and 1685 women enrolled in Lusaka (1022 VCT, 663 CVCT). HIV prevalence was 14% in Kigali, and 27% in Lusaka. Loss to follow up was more common in Kigali than Lusaka (33% vs. 24%, p = 0.000). In Lusaka, HIV‐positive and HIV‐negative women had significantly different loss‐to‐follow‐up rates (30% vs. 22%, p = 0.002). CVCT was associated with reduced loss to follow up: in Kigali, 31% of couples versus 36% of women testing alone (p = 0.011); and in Lusaka, 22% of couples versus 25% of women testing alone (p = 0.137). Among HIV‐positive women with follow up, CVCT had no impact on nevirapine use (86‐89% in Kigali; 78‐79% in Lusaka).ConclusionsWeekend CVCT, though new, was feasible in both capital cities. The beneficial impact of CVCT on loss to follow up was significant, while nevirapine compliance was similar in women tested alone or with their partners. Pre‐measured nevirapine syrup syringes provided flexibility to HIV‐positive mothers in Lusaka, but may have contributed to study loss to follow up. These two prevention interventions remain a challenge, with CVCT still operating without supportive government policy in Zambia.

Little is known about how the information presented in the informed consent process influences study outcomes among participants. This study examines the influence of informed consent content on reported baseline contraceptive knowledge and concerns among two groups of HIV‐serodiscordant and seroconcordant HIV‐positive couples enrolled in research projects at an HIV research center in Lusaka, Zambia. We found significant differences in the reporting of contraceptive knowledge and concerns between couples viewing consent materials that included detailed information about contraception and those viewing consent materials that lacked the detailed information. We conclude that the design of informed consent materials should strike a balance between ensuring that participants give truly informed consent and educating participants in ways that do not compromise the assessment of the impact of behavioral interventions.

BACKGROUND: Integrating family planning interventions with HIV studies in developing countries has been shown to prevent mother-to-child HIV transmission and simultaneously reduce HIV and unintended pregnancy in high-risk populations. As part of a prospective cohort study on HIV incidence and risk factors in Zambian women having unprotected sex, we also offered family planning counseling and immediate access to long-acting reversible contraceptives. Although long-acting reversible contraceptives are the most effective form of contraception, many Zambian women are limited to oral or injectable methods due to lack of knowledge or method availability. This project offers single mothers enrolled in a cohort study information about and access to long-acting reversible contraceptives at enrollment and at each follow-up visit. OBJECTIVE: This study evaluates how fertility intentions affect long-acting reversible contraceptive utilization in HIV-negative single mothers in Zambia. Our primary outcome was long-acting reversible contraceptive use throughout study participation. We also estimated rates of long-acting reversible contraceptive uptake and discontinuation. We specifically studied single mothers because they are at high risk for unintended pregnancy, which can have significant negative ramifications on their financial, social and psychological circumstances. STUDY DESIGN: From 2012–2017, Zambia Emory HIV Research Project recruited 521 HIV-negative single mothers between the ages of 18–45 years from government clinics in Lusaka and Ndola, Zambia's two largest cities. Participants were followed every three months for up to five years. At each visit, we discussed fertility goals and contraceptive options and offered a long-acting reversible method to any woman who was not pregnant or already using a long-acting reversible or permanent contraceptive method. Data was collected on demographic factors, sexual behavior and reproductive history. Multivariable logistic regression was used to model baseline fertility ...

OBJECTIVE: To present the incremental cost from the payer's perspective and effectiveness of couples' family planning counseling (CFPC) with long-acting reversible contraception (LARC) access integrated with couples' voluntary HIV counseling and testing (CVCT) in Zambia. This integrated program is evaluated incremental to existing individual HIV counseling and testing and family planning services. DESIGN: Implementation and modeling SETTING: 55 government health facilities in Zambia SUBJECTS: Patients in government health facilities INTERVENTION: Community health workers and personnel promoted and delivered integrated CVCT+CFPC from March 2013-September 2015. MAIN OUTCOME MEASURES: We report financial costs of actual expenditures during integrated program implementation and outcomes of CVCT+CFPC uptake and LARC uptake. We model primary outcomes of cost-per-: adult HIV infections averted by CVCT, unintended pregnancies averted by LARC, couple-years of protection against unintended pregnancy by LARC, and perinatal HIV infections averted by LARC. Costs and outcomes were discounted at 3%/year. RESULTS: Integrated program costs were $3,582,186 (2015 USD), 82,231 couples received CVCT+CFPC, and 56,409 women received LARC insertions. The program averted an estimated 7,165 adult HIV infections at $384/adult HIV infection averted over a 5-year time horizon. The program also averted 62,265 unintended pregnancies and was cost-saving for measures of cost-per-unintended pregnancy averted, cost-per-couple-year of protection against unintended pregnancy, and cost-per-perinatal HIV infection averted assuming 3 years of LARC use. CONCLUSIONS: Our intervention was cost-savings for CFPC outcomes and CVCT was effective and affordable in Zambia. Integrated couples-focused HIV and family planning was feasible, affordable, and leveraged HIV and unintended pregnancy prevention.

AbstractIntroductionCouples' voluntary HIV counselling and testing (CVCT) is a high‐impact HIV prevention intervention in Rwanda and Zambia. Our objective was to model the cost‐per‐HIV infection averted by CVCT in six African countries guided by an HIV prevention cascade framework. The HIV prevention cascade as yet to be applied to evaluating CVCT effectiveness or cost‐effectiveness.MethodsWe defined a priority population for CVCT in Africa as heterosexual adults in stable couples. Based on our previous experience nationalizing CVCT in Rwanda and scaling‐up CVCT in 73 clinics in Zambia, we estimated HIV prevention cascade domains of motivation for use, access and effectiveness of CVCT as model parameters. Costs‐per‐couple tested were also estimated based on our previous studies. We used these parameters as well as country‐specific inputs to model the impact of CVCT over a five‐year time horizon in a previously developed and tested deterministic compartmental model. We consider six countries across Africa with varied HIV epidemics (South Africa, Zimbabwe, Kenya, Tanzania, Ivory Coast and Sierra Leone). Outcomes of interest were the proportion of HIV infections averted by CVCT, nationwide CVCT implementation costs and costs‐per‐HIV infection averted by CVCT. We applied 3%/year discounting to costs and outcomes. Univariate and Monte Carlo multivariate sensitivity analyses were conducted.ResultsWe estimated that CVCT could avert between 54% (Sierra Leone) and 62% (South Africa) of adult HIV infections. Average costs‐per‐HIV infection averted were lowest in Zimbabwe ($550) and highest in South Africa ($1272). Nationwide implementations would cost between 7% (Kenya) and 21% (Ivory Coast) of a country's President's Emergency Plan for AIDS Relief (PEPFAR) budget over five years. In sensitivity analyses, model outputs were most sensitive to estimates of cost‐per‐couple tested; the proportion of adults in heterosexual couples and HIV prevention cascade domains of CVCT motivation and access.ConclusionsOur model indicates that nationalized CVCT could prevent over half of adult HIV infections for 7% to 21% of the modelled countries' five‐year PEPFAR budgets. While other studies have indicated that CVCT motivation is high given locally relevant promotional and educational efforts, without required indicators, targets and dedicated budgets, access remains low.

Background: The impact and cost-effectiveness of couples' voluntary HIV counselling and testing (CVCT) has not been quantified in real-world settings. We quantify cost-per-HIV-infection averted by CVCT in Zambia from the donor's perspective. Methods: From 2010 to 2016, CVCT was established in 73 Zambian government clinics. The cost-per-HIV-infection averted (CHIA) of CVCT was calculated using observed expenditures and effectiveness over longitudinal follow-up. These observed measures parameterized hypothetical 5-year nationwide implementations of: 'CVCT'; 'treatment-as-prevention (TasP) for discordant couples' identified by CVCT; and 'population TasP' for all HIV+ cohabiting persons identified by individual testing. Results: In all, 207 428 couples were tested (US $52/couple). Among discordant couples in which HIV+ partners self-reported antiretroviral therapy (ART), HIV incidence was 8.5/100 person-years before and 1.8/100 person-years after CVCT (79% reduction). Corresponding reductions for non-ART-using discordant and concordant negative couples were 63% and 47%, respectively. CVCT averted an estimated 58% of new infections at US $659 CHIA. In nationwide implementation models, CVCT would prevent 17 times the number of infections vs 'TasP for discordant couples' at 86% of the cost, and nine times the infections vs 'population TasP' at 28% of the cost. Conclusions: CVCT is a cost-effective, feasible prevention strategy in Zambia. We demonstrate the novel, added effectiveness of providing CVCT to ART users, for whom ART use alone only partially mitigated transmission risk. Our results indicate a major policy shift (supporting development of CVCT indicators, budgets and targets) and have clinical implications (suggesting promotion of CVCT in ART clinics as a high-impact prevention strategy).

Background In 2015, an estimated 303 000 women died in pregnancy and childbirth. Obstetric haemorrhage, sepsis, and hypertensive disorders of pregnancy account for more than 50% of maternal deaths worldwide. There are effective treatments for these pregnancy complications, but they require early detection by measurement of vital signs and timely administration to save lives. The primary aim of this trial was to determine whether implementation of the CRADLE Vital Sign Alert and an education package into community and facility maternity care in low-resource settings could reduce a composite of all-cause maternal mortality or major morbidity (eclampsia and hysterectomy). Methods We did a pragmatic, stepped-wedge, cluster-randomised controlled trial in ten clusters across Africa, India, and Haiti, introducing the device into routine maternity care. Each cluster contained at least one secondary or tertiary hospital and their main referral facilities. Clusters crossed over from existing routine care to the CRADLE intervention in one of nine steps at 2-monthly intervals, with CRADLE devices replacing existing equipment at the randomly allocated timepoint. A computer-generated randomly allocated sequence determined the order in which the clusters received the intervention. Because of the nature of the intervention, this trial was not masked. Data were gathered monthly, with 20 time periods of 1 month. The primary composite outcome was at least one of eclampsia, emergency hysterectomy, and maternal death. This study is registered with the ISRCTN registry, number ISRCTN41244132. Findings Between April 1, 2016, and Nov 30, 2017, among 536 223 deliveries, the primary outcome occurred in 4067 women, with 998 maternal deaths, 2692 eclampsia cases, and 681 hysterectomies. There was an 8% decrease in the primary outcome from 79·4 per 10 000 deliveries pre-intervention to 72·8 per 10 000 deliveries post-intervention (odds ratio [OR] 0·92, 95% CI 0·86–0·97; p=0·0056). After planned adjustments for variation in event rates between and within clusters over time, the unexpected degree of variability meant we were unable to judge the benefit or harms of the intervention (OR 1·22, 95% CI 0·73–2·06; p=0·45). Interpretation There was an absolute 8% reduction in primary outcome during the trial, with no change in resources or staffing, but this reduction could not be directly attributed to the intervention due to variability. We encountered unanticipated methodological challenges with this trial design, which can provide valuable learning for future research and inform the trial design of future international stepped-wedge trials.
