RESUMO

BACKGROUND: There is unmet need for family planning in Rwanda. We previously developed an evidence-based couples' family planning counseling (C)FPC program in the capital city that combines: (1) fertility goal-based family planning counseling with a focus on long-acting reversible contraceptive (LARC) for couples wishing to delay pregnancy; (2) health center capacity building for provision of LARC methods, and (3) LARC promotion by community health workers (CHW) trained in community-based provision of oral and injectable contraception. From 2015 to 2016, this service was integrated into eight government health centers in Kigali, reaching 6072 clients and resulting in 5743 LARC insertions. METHODS: From May to July 2016, we conducted cross-sectional health center needs assessments in 30 rural health centers using surveys, key informant interviews, logbook extraction, and structured observations. The assessment focused on the infrastructure, materials, and human resources needed for LARC demand creation and provision. RESULTS: Few nurses had received training in LARC insertion [41% implant, 27% intrauterine device (IUD)]. All health centers reported working with CHW, but none trained in LARC promotion. Health centers had limited numbers of IUDs (median 10), implants (median 39), functional gynecological exam tables (median 2), and lamps for viewing the cervix (median 0). Many did not have backup power supplies (40%). Most health centers reported no funding partners for family planning assistance (60%). Per national guidelines, couples' voluntary HIV counseling and testing (CVCT) was provided at the first antenatal visit at all clinics, reaching over 80% of pregnant women and their partners. However, only 10% of health centers had integrated family planning and HIV services. CONCLUSIONS: To successfully implement (C)FPC and LARC services in rural health centers across Rwanda, material and human resource capacity for LARC provision will need to be greatly strengthened through equipment (gynecological exam tables, sterilization capacity, lamps, and backup power supplies), provider trainings and follow-up supervision, and new funding partnerships. Simultaneously, awareness of LARC methods will need to be increased among couples through education and promotion to ensure that demand and supply scale up together. The potential for integrating (C)FPC with ongoing CVCT in antenatal clinics is unique in Africa and should be pursued.

RESUMO

INTRODUCTION: Couples' 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. METHODS: We 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. RESULTS: We 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. CONCLUSIONS: Our 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.

RESUMO

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 modelling. SETTING: Fifty-five 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 to 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% per 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 7165 adult HIV infections at $384 per 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. CONCLUSION: 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.

RESUMO

The sexually transmitted infections (STIs) chlamydia (CT) and gonorrhea (NG) are often asymptomatic in women and undetected by syndromic management, leading to complications such as pelvic inflammatory disease, infertility, and ectopic pregnancy. Molecular testing, such as the GeneXpert CT/NG assay, is highly sensitive, but cost restraints preclude implementation of these technologies in resource-limited settings. Pooled testing is one strategy to reduce the cost per sample, but the extent of savings depends on disease prevalence. The current study describes a pooling strategy based on identification of sociodemographic and laboratory factors associated with CT/NG prevalence in a high-risk cohort of Zambian female sex workers and single mothers conducted from 2016 to 2019. Factors associated with testing positive for CT/NG via logistic regression modeling included city, younger age, lower education, long-acting reversible contraception usage, Trichomonas vaginalis infection, bacterial vaginosis, and incident syphilis infection. Based on these factors, the study population was stratified into high-, intermediate-, and low-prevalence subgroups and tested accordingly-individually, pools of 3, or pools of 4, respectively. The cost per sample was reduced from $18 to as low as $9.43 in the low-prevalence subgroup. The checklist tool and pooling approach described can be used in a variety of treatment algorithms to lower the cost per sample and increase access to molecular STI screening. This is particularly valuable in resource-limited settings to detect and treat asymptomatic CT/NG infections missed by traditional syndromic management.

RESUMO

BACKGROUND: Zambia's total fertility rate (5 births per woman) and adult HIV prevalence (11.5%) are among the highest in the world, with heterosexual couples being the most affected group. Jointly counseling and testing couples for HIV has reduced up to 58% of new HIV infections in Zambian clinics. Married women using contraceptives in Zambia have a high (20%) unmet need for family planning and low (8.6%) uptake of cost-effective long-acting reversible contraceptives. We present an integrated counseling, testing, and family-planning program to prevent HIV and unplanned pregnancy in Zambia. OBJECTIVE: The objective of this study was to integrate effective HIV prevention and family-planning services for Zambian couples. STUDY DESIGN: A 3 year program (2013-2016) progressively integrated the promotion and provision of couples' voluntary HIV counseling and testing and long-acting reversible contraceptives. The program was based in 55 urban and 215 rural government clinics across 33 districts. In the first year, a couples' family-planning counseling training program was developed and combined with existing couples HIV counseling training materials. To avoid congestion during routine clinic hours, joint counseling services were initially provided on weekends, while nurses were trained in intrauterine device and hormonal implant insertion and removal during weekday family-planning services. Demand was created through mutual referral between weekend and weekday programs and by clinic staff, community health workers, and satisfied family-planning clients. When the bulk of integrated service training was completed, the program transitioned services to routine weekday clinic hours, ensuring access to same-day services. Performance indicators included number of staff trained, clients served, integrated service referrals, HIV infections averted, and unplanned pregnancies averted. RESULTS: A stepwise approach trained high-performing service providers to be trainers and used high-volume clinics for practicum training of the next generation. In total, 1201 (391 urban, 810 rural) counselors were trained and served 120,535 urban and 87,676 rural couples. In urban clinics, 236 nurses inserted 65,619 long-acting reversible contraceptives, while in rural clinics, 243 nurses inserted 35,703 implants and intrauterine devices. The program prevented an estimated 12,869 urban and 8279 rural adult HIV infections, and 98,626 unintended urban pregnancies. In the final year, the proportion of clients receiving joint counseling services on weekdays rose from 11% to 89%, with many referred from within clinics including HIV testing and treatment services (32%), outpatient department (31%), family planning (16%), and infant vaccination (15%). The largest group of clients requesting long-acting reversible contraceptives (45%) did so after joint fertility goal-based counseling, confirming the high impact of this couple-focused demand creation approach. Remaining family-planning clients responded to referrals from clinic nurses (34%), satisfied implant/intrauterine device users (13%), or community health workers (8%). CONCLUSION: Integrated HIV and unplanned pregnancy prevention can be implemented in low-resource public sector facilities. Combination services offered to couples mutually leverage HIV prevention and unplanned pregnancy prevention. The addition of long-acting reversible contraceptives is an important complement to the method mix available in government clinics. Demand creation in the clinic and in the community must be coordinated with a growing supply of well-trained providers.

RESUMO

BACKGROUND: We coordinated community health worker (CHW) promotions with training and support of government clinic nurses to increase uptake of long-acting reversible contraception (LARC), specifically the copper intrauterine device (IUD) and the hormonal implant, in Kigali, Rwanda. METHODS: From August 2015 to September 2016, CHW provided fertility goal-based family planning counseling focused on LARC methods, engaged couples in family planning counseling, and provided written referrals to clients expressing interest in LARC methods. Simultaneously, we provided didactic and practical training to clinic nurses on LARC insertion and removal. We evaluated: 1) aggregate pre- versus post-implementation LARC uptake as a function of CHW promotions, and 2) demographic factors associated with LARC uptake among women responding to CHW referrals. RESULTS: 7712 referrals were delivered by 184 CHW affiliated with eight government clinics resulting in 6072 family planning clinic visits (79% referral uptake). 95% of clinic visits resulted in LARC uptake (16% copper IUD, 79% hormonal implant). The monthly average for IUD insertions doubled from 29 prior to service implementation to 61 after (p < 0.0001), and the monthly average for implant insertions increased from 109 to 309 (p < 0.0001). In adjusted analyses, LARC uptake was associated (p < 0.05) with the CHW referral being issued to the couple (versus the woman alone, adjusted odds ratio, aOR = 2.6), having more children (aOR = 1.3), desiring more children (aOR = 0.8), and having a religious affiliation (aOR = 2.9 Protestant, aOR = 3.1 Catholic, aOR = 2.5 Muslim each versus none/other). Implant versus non-LARC uptake was associated with having little or no education; meanwhile, having higher education was associated with IUD versus implant uptake. CONCLUSIONS: Fertility goal-based and couple-focused family planning counseling delivered by CHW, coupled with LARC training and support of nursing staff, substantially increased uptake of LARC methods.

RESUMO

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).

RESUMO

OBJECTIVES: To evaluate rates of long-term survival in a prospective, longitudinal, closed HIV cohort in Africa between 1986 and 2006. METHODS: A total of 548 HIV-infected Rwandan women were recruited from prenatal clinics in Kigali and followed at 3-6 month intervals to February 2006. Overall, 401 women (73%) were HIV positive at initial cross-sectional testing in 1986 (seroprevalent cohort) and 147 women (27%) were initially HIV negative but seroconverted during follow-up from 1986 to 1993 (seroincident cohort). Kaplan-Meier survival methods were used to calculate survival times censored in mid-2003. RESULTS: In February 2006, 109 women (20%) remained alive in the cohort. Time to 50% non-genocide mortality was 11.9 years among seroincident women and 8.9 years among seroprevalent women. Smoothed mortality rates increased with duration of follow-up to a peak of 0.12 deaths per person-year at 9.5 years of follow-up but subsequently declined. After 15 years of follow-up (pre-HAART introduction), the survival probability was 36% for seroincident women and 26% for seroprevalent women. Most survivors had virological and immunological evidence of disease progression. The median CD4 cell count of survivors declined from 447 cells/mul in 1998 to 268 cells/mul in 2003. Among survivors, 57 women (52%) met treatment criteria and initiated antiretroviral treatment by 2006. CONCLUSION: Although median survival times in this cohort were similar to those observed in high-income countries, the rates of long-term survival after 15 years of follow-up were higher than expected. A levelling off of mortality rates during the late stages of follow-up may explain this high rate of long-term survival.
