Approaches to improve and adapt maternal mortality estimations in low- and middle-income countries: A scoping review.

BACKGROUND: In the absence of robust vital registration systems, many low- and middle-income countries (LMICs) rely on national surveys or routine surveillance systems to estimate the maternal mortality ratio (MMR). Although the importance of MMR estimates in ending preventable maternal deaths is acknowledged, there is limited research on how different approaches are used and adapted, and how these adaptations function. OBJECTIVES: To assess methods for estimating maternal mortality in LMICs and the rationale for these modifications. SEARCH STRATEGY: A literature search with the terms "maternal death", "surveys" and "low- and middle-income countries" was performed in Medline, Embase, Web of Science, Scopus, CINAHL, APA PsycINFO, ERIC, and IBSS from January 2013 to March 17, 2023. SELECTION CRITERIA: Studies were eligible if their main focus was to compare, adapt, or assess methods to estimate maternal mortality in LMICs. DATA COLLECTION AND ANALYSIS: Titles and abstracts were screened using Rayyan. Relevant articles were independently reviewed by two reviewers against inclusion criteria. Data were extracted on mortality measurement methods, their context, and results. MAIN RESULTS: Nineteen studies were included, focusing on data completeness, subnational estimates, and community involvement. Routinely generated MMR estimates are more complete when multiple data sources are triangulated, including data from public and private health facilities, the community, and local authorities (e.g. vital registration, police reports). For subnational estimates, existing (e.g. the sisterhood method and reproductive-age mortality surveys [RAMOS]) and adapted methods (e.g. RAMOS 4 + 2 and Pictorial Sisterhood Method) provided reliable confidence intervals. Community engagement in data collection increased community awareness of maternal deaths, provided local ownership, and was expected to reduce implementation costs. However, most studies did not include a cost-effectiveness analysis. CONCLUSION: Household surveys with community involvement and RAMOS can be used to increase data validity, improve local awareness of maternal mortality estimates, and reduce costs in LMICs.

Community delivery of malaria intermittent preventive treatment in pregnancy: protocol of a quasi-experimental evaluation through multistage cluster sampling household surveys in four sub-Saharan African countries.

BACKGROUND: In sub-Saharan Africa (SSA), millions of pregnant women are exposed to malaria infection. The cornerstone of the WHO strategy to prevent malaria in pregnancy in moderate to high-transmission areas is the administration of intermittent preventive treatment (IPTp) with sulfadoxine-pyrimethamine at each scheduled antenatal care (ANC) visit. However, overall coverage remains low. 'Transforming IPT for Optimal Pregnancy' (TIPTOP) project aims at delivering IPTp at the community level (C-IPTp) to complement ANC provision with the goal of increasing IPTp coverage and improving maternal and infant's health. This protocol describes the approach to measure the effect of this strategy through household surveys (HHS) in four SSA countries: Democratic Republic of Congo (DRC), Madagascar, Mozambique and Nigeria. METHODS AND ANALYSIS: A quasi-experimental evaluation has been designed. Delivery of C-IPTp will start first in one area per country, and later it will be extended to two more areas per country. HHS will be carried out before C-IPTp implementation in all study sites, at midterm in initial implementation areas, and after the implementation in all project areas. A multistage cluster sampling method will be followed for the selection of participants. Women of reproductive age who had a pregnancy that ended in the 6 or 12 months prior to the interview, depending on the survey, will be invited to participate by responding to a questionnaire. The main indicators will be coverage of three or more doses of IPTp and attendance to at least four ANC visits. A difference-in-difference analysis will be performed to evaluate the effectiveness of C-IPTp. ETHICS AND DISSEMINATION: The project has been reviewed by the ethics committees of WHO, Hospital Clinic of Barcelona and all project country boards. Project results will be disseminated to in-country stakeholders and at regional and international meetings. TIPTOP project aims to develop and disseminate global recommendations for C-IPTp delivery. TRIAL REGISTRATION NUMBER: NCT03600844; Pre-results.

Coverage of intermittent preventive treatment of malaria in pregnancy in four sub-Saharan countries: findings from household surveys.

BACKGROUND: Intermittent preventive treatment in pregnancy (IPTp) with sulphadoxine-pyrimethamine (SP) is a key malaria prevention strategy in areas with moderate to high transmission. As part of the TIPTOP (Transforming IPT for Optimal Pregnancy) project, baseline information about IPTp coverage was collected in eight districts from four sub-Saharan countries: Democratic Republic of Congo (DRC), Madagascar, Mozambique and Nigeria. METHODS: Cross-sectional household surveys were conducted using a multistage cluster sampling design to estimate the coverage of IPTp and antenatal care attendance. Eligible participants were women of reproductive age who had ended a pregnancy in the 12 months preceding the interview and who had resided in the selected household during at least the past 4 months of pregnancy. Coverage was calculated using percentages and 95% confidence intervals. RESULTS: A total of 3911 women were interviewed from March to October 2018. Coverage of at least three doses of IPTp (IPTp3+) was 22% and 24% in DRC project districts; 23% and 12% in Madagascar districts; 11% and 16% in Nigeria local government areas; and 63% and 34% in Mozambique districts. In DRC, Madagascar and Nigeria, more than two-thirds of women attending at least four antenatal care visits during pregnancy received less than three doses of IPTp. CONCLUSIONS: The IPTp3+ uptake in the survey districts was far from the universal coverage. However, one of the study districts in Mozambique showed a much higher coverage of IPTp3+ than the other areas, which was also higher than the 2018 average national coverage of 41%. The reasons for the high IPTp3+ coverage in this Mozambican district are unclear and require further study.

Presence of doctors and obstetrician/gynecologists for patients with maternal complications in hospitals in six provinces of Indonesia.

OBJECTIVE: To describe doctors' and specialist physicians' availability to manage obstetric complications in hospitals in six provinces of Indonesia. METHODS: Data from a nonrandomized, quasi-experimental pre-post evaluation study were used to describe the distribution of providers by each cadre of worker and assess the availability of doctors and obstetrician/gynecologists (ob/gyns) for consultations for women experiencing postpartum hemorrhage or pre-eclampsia/eclampsia, disaggregated by hospital type, province, referral status, and by time of day of provider consultation. RESULTS: Among hospitals that should have comprehensive emergency obstetric and newborn care (CEmONC) services available 24 hours a day, 7 days a week, many did not have a doctor available to manage obstetric complications as they presented, despite there being an average of seven ob/gyns and four doctors registered for service across all facilities. Slightly over 50% of obstetric emergency cases admitted with postpartum hemorrhage and severe pre-eclampsia/eclampsia did not receive a consultation from an ob/gyn. Among the patients who received consultations, about 70% received consultations by phone or SMS. CONCLUSION: Findings from this study indicate that persistent issues of maldistribution of maternal and newborn specialists and high absence rates of both doctors and ob/gyns at CEmONC hospitals during obstetric emergencies undermines Indonesia's efforts to reduce high maternal mortality rates.

Assessing the effect of the Expanding Maternal and Neonatal Survival program on improving stabilization and referral for maternal and newborn complications in Indonesia.

OBJECTIVE: To determine if the Expanding Maternal and Neonatal Survival (EMAS) program was associated with improved effectiveness of the referral system in Indonesia to facilitate timely and effective management of complications experienced by women and newborns. METHODS: Poisson regression using longitudinal monitoring data was used to assess the impact of the EMAS program on stabilization practices prior to referral. Data from a nonrandomized quasi-experimental pre-post evaluation study were used to assess the impact of the EMAS program along the referral pathway using χ2 analysis. RESULTS: Monitoring data demonstrated improvements in intervention areas for stabilization of pre-eclampsia/eclampsia (24% vs 61%, incidence rate ratio [IRR] 2.4; 95% confidence interval [CI], 2.3-2.6) and treatment of newborns with suspected severe infection (30% vs 54%, IRR 2.0; 95% CI, 1.6-2.4) prior to referral. The EMAS program was associated with significantly higher levels of communication, advanced notification, back referral, and hospital emergency readiness and staff preparedness compared with the comparison arm. CONCLUSION: The EMAS program contributed to improvements in the management of obstetric and newborn complications, including communication, transportation, and preparation of pregnant mothers in need of referral and hospital emergency readiness and staff preparedness.

The effect of Expanding Maternal and Neonatal Survival interventions on improving the coverage of labor monitoring and complication prevention practices in hospitals in Indonesia: A difference-in-difference analysis.

OBJECTIVE: To assess whether the Expanding Maternal and Neonatal Survival (EMAS) program was associated with improved care provided during hospital-based childbirth. METHODS: A quasi-experimental study with two rounds of data collection examined whether EMAS interventions improved facility-based labor and childbirth care. Direct clinical observations were conducted for 1208 deliveries across 13 hospitals in 12 districts. Primary outcome measures included implementation of standard practices to reduce the risk of complications during labor and childbirth for both women and newborns. RESULTS: Adjusted difference-in-difference analysis compared the mean difference in quality scores between EMAS intervention hospitals and comparison sites and consistently found significantly better performance in EMAS sites: 14 points higher for labor monitoring (ß-coefficient 14.1; 95% confidence interval [CI], 7.1-21.0); 38 points higher for newborn resuscitation readiness (ß-coefficient 38.1; 95% CI, 31.1-45.2); and 33 points higher for infection prevention practices (ß-coefficient 32.6; 95% CI, 28.5-36.8). CONCLUSION: EMAS approaches emphasizing facility readiness and adherence to performance standards significantly improved labor monitoring and complication prevention practices during childbirth.

Changes in obstetric case fatality and early newborn mortality rates in hospitals after the implementation of the Expanding Maternal and Neonatal Survival program in Indonesia: Results from a health information system.

OBJECTIVES: Case fatality rates (CFRs) are often used as the key indicator for the measurement of quality of care at hospitals. We examine the trends of obstetric CFRs and very early neonatal mortality rates at hospitals in selected districts of Indonesia after implementation of a facility-based maternal and neonatal health intervention-the Expanding Maternal and Neonatal Survival (EMAS) program. METHODS: Random-effects Poisson regression models were fitted to routine facility data collected from 101 hospitals over approximately 4 years. Predicted incidence rates from the models were used for ascertaining the changes in CFRs and very early neonatal mortality rates during the EMAS intervention period. RESULTS: The obstetric CFR from any maternal complications decreased significantly by 50% (adjusted incidence rate ratio [IRR] 0.50; 95% confidence interval [CI] 0.42-0.61) at hospitals after the implementation of the EMAS program. On average, the CFR decreased from 5.4 to 2.6 deaths per 1000 cases of obstetric complications admitted during the program period. The very early neonatal mortality rate (deaths within 24 hours of birth) decreased by 21% (IRR 0.79; 95% CI, 0.65-0.96). CONCLUSION: Our study suggests that overall obstetric case fatality and very early neonatal mortality rates-two indicators for tracking the quality of emergency obstetric care-decreased significantly at hospitals after the implementation of the EMAS intervention program in Indonesia.

Assessment of knowledge of evidence-based maternal and newborn care practices among midwives and nurses in six provinces in Indonesia.

OBJECTIVE: To investigate knowledge of obstetric and newborn care guidelines among midwives and nurses in Indonesia, whether knowledge differs between health centers (puskesmas) and hospitals, and factors associated with knowledge. METHODS: Cross-sectional knowledge assessments of 409 health workers in 56 public and private health facilities across six provinces were conducted. Poisson regression models examined relationships between knowledge; health workers' age; in-service education about labor, delivery, or newborn care in the past 3 years; and supervision in the past 3 months. RESULTS: The mean maternal care score among the 302 midwives for the 10 questions was 3.3 (standard deviation [SD]1.8). Hospital midwives performed slightly better than puskesmas midwives: 3.8 correct (confidence interval [CI], 3.43-4.19) vs 3.0 correct (CI, 2.77-3.26), which was a statistically significant difference. The mean knowledge score for three newborn care questions was 0.79 (SD 0.87). There was no statistically significant difference in scores between hospital workers and puskesmas providers (0.80 correct [CI, 0.64-1.00] vs 0.78 correct [CI, 0.67-0.92]). Receipt of supervision was not associated with maternal or newborn health knowledge scores. CONCLUSIONS: There is a need to improve knowledge of maternal and newborn care guidelines among midwives and nurses in Indonesia.

Case Study: Clinical Governance as an Approach to Improve Maternal and Newborn Health in 22 Hospitals in Indonesia.

Clinical governance is a concept used to improve management, accountability and the provision of quality healthcare. An approach to strengthen clinical governance as a means to improve the quality of maternal and newborn care in Indonesia was developed by the Expanding Maternal and Neonatal Survival (EMAS) Program. This case study presents findings and lessons learned from EMAS program experience in 22 hospitals where peer-to-peer mentoring supported staff in strengthening clinical governance from 2012-2015. Efforts resulted in improved hospital preparedness and significantly increased the odds of facility-level coverage for three evidence-based maternal and newborn healthcare interventions.

Newborn care practices at home and in health facilities in 4 regions of Ethiopia.

BACKGROUND: Ethiopia is one of the ten countries with the highest number of neonatal deaths globally, and only 1 in 10 women deliver with a skilled attendant. Promotion of essential newborn care practices is one strategy for improving newborn health outcomes that can be delivered in communities as well as facilities. This article describes newborn care practices reported by recently-delivered women (RDWs) in four regions of Ethiopia. METHODS: We conducted a household survey with two-stage cluster sampling to assess newborn care practices among women who delivered a live baby in the period 1 to 7 months prior to data collection. RESULTS: The majority of women made one antenatal care (ANC) visit to a health facility, although less than half made four or more visits and women were most likely to deliver their babies at home. About one-fifth of RDWs in this survey had contact with Health Extension Workers (HEWS) during ANC, but nurse/midwives were the most common providers, and few women had postnatal contact with any health provider. Common beneficial newborn care practices included exclusive breastfeeding (87.6%), wrapping the baby before delivery of the placenta (82.3%), and dry cord care (65.2%). Practices contrary to WHO recommendations that were reported in this population of recent mothers include bathing during the first 24 hours of life (74.7%), application of butter and other substances to the cord (19.9%), and discarding of colostrum milk (44.5%). The results suggest that there are not large differences for most essential newborn care indicators between facility and home deliveries, with the exception of delayed bathing and skin-to-skin care. CONCLUSIONS: Improving newborn care and newborn health outcomes in Ethiopia will likely require a multifaceted approach. Given low facility delivery rates, community-based promotion of preventive newborn care practices, which has been effective in other settings, is an important strategy. For this strategy to be successful, the coverage of counseling delivered by HEWs and other community volunteers should be increased.

Evaluation of a quality improvement intervention to prevent mother-to-child transmission of HIV (PMTCT) at Zambia defence force facilities.

BACKGROUND: The Zambian Defence Force (ZDF) is working to improve the quality of services to prevent mother-to-child transmission of HIV (PMTCT) at its health facilities. This study evaluates the impact of an intervention that included provider training, supportive supervision, detailed performance standards, repeated assessments of service quality, and task shifting of group education to lay workers. METHODS: Four ZDF facilities implementing the intervention were matched with four comparison sites. Assessors visited the sites before and after the intervention and completed checklists while observing 387 antenatal care (ANC) consultations and 41 group education sessions. A checklist was used to observe facilities' infrastructure and support systems. Bivariate and multivariate analyses were conducted of findings on provider performance during consultations. RESULTS: Among 137 women observed during their initial ANC visit, 52% came during the first 20 weeks of pregnancy, but 19% waited until the 28th week or later. Overall scores for providers' PMTCT skills rose from 58% at baseline to 73% at endline (p=0.003) at intervention sites, but remained stable at 52% at comparison sites. Especially large gains were seen at intervention sites in family planning counseling (34% to 75%, p=0.026), HIV testing during return visits (13% to 48%, p=0.034), and HIV/AIDS management during visits that did not include an HIV test (1% to 34%, p=0.004). Overall scores for providers' ANC skills rose from 67% to 74% at intervention sites, but declined from 65% to 59% at comparison sites; neither change was significant in the multivariate analysis. Overall scores for group education rose from 87% to 91% at intervention sites and declined from 78% to 57% at comparison sites. The overall facility readiness score rose from 73% to 88% at intervention sites and from 75% to 82% at comparison sites. CONCLUSIONS: These findings are relevant to civilian as well as military health systems in Zambia because the two are closely coordinated. Lessons learned include: the ability of detailed performance standards to draw attention to and strengthen areas of weakness; the benefits of training lay workers to take over non-clinical PMTCT tasks; and the need to encourage pregnant women to seek ANC early.

Improving performance of Zambia Defence Force antiretroviral therapy providers: evaluation of a standards-based approach.

BACKGROUND: The Zambia Defence Force (ZDF) has applied the Standards-Based Management and Recognition (SBM-R®) approach, which uses detailed performance standards, at some health facilities to improve HIV-related services offered to military personnel and surrounding civilian communities. This study examines the effectiveness of the SBM-R approach in improving facility readiness and provider performance at ZDF facilities. METHODS: We collected data on facility readiness and provider performance before and after the 2010-2012 intervention at 4 intervention sites selected for their relatively poor performance and 4 comparison sites. Assessors observed whether each facility met 16 readiness standards and whether providers met 9 performance standards during consultations with 354 returning antiretroviral therapy (ART) clients. We then calculated the percentages of criteria achieved for each readiness and performance standard and conducted bivariate and multivariate analyses of provider performance data. RESULTS: Facilities' ART readiness scores exceeded 80% before the intervention at both intervention and comparison sites. At endline, scores improved on 4 facility readiness standards in the intervention group but on only 1 standard in the comparison group. Multivariate analysis found that the overall provider performance score increased significantly in the intervention group (from 58% to 84%; P<.01) but not in the comparison group (from 62% to 70%). The before-and-after improvement in scores was significantly greater among intervention sites than among comparison sites for 2 standards-initial assessment of the client's condition and nutrition counseling. CONCLUSION: The standards-based approach, which involved intensive and mutually reinforcing intervention activities, showed modest improvements in some aspects of providers' performance during ART consultations. Further research is needed to determine whether improvements in provider performance affect client outcomes such as adherence to ART.

HIV/AIDS misconceptions among Latinos: findings from a population-based survey of California adults.

Misconceptions about HIV/AIDS among Latino adults (N = 454) in California were examined using data from a population-based telephone survey conducted in 2000. Common misconceptions concerning modes of HIV transmission included transmission via mosquito or animal bite (64.1%), public facilities (48.3%), or kissing someone on the cheek (24.8%). A composite misconceptions score was constructed. Correlations between the composite measure and other HIV/AIDS-related beliefs were examined. Latinos with a higher level of misconceptions were more likely to report higher self-perceived risk of HIV infection, and discomfort with infected individuals in a school and in a food setting. Results from multiple linear regression analysis indicated that individuals 45 years and older, those who were interviewed in Spanish, and those with lower education or income levels had a higher degree of misconceptions. The results suggest the need for targeted education efforts to reduce HIV/AIDS misconceptions among Latino adults in California.

Knowledge of sexual partner's HIV serostatus and serosorting practices in a California population-based sample of men who have sex with men.

OBJECTIVES: To describe knowledge of primary and secondary sexual partner's HIV serostatus and sexual practices, including serosorting, among men who have sex with men (MSM) living in California. METHODS: Men who self-identified as gay/bisexual in the 2001 California Health Interview Survey, a statewide biennial random-digit-dial survey interviewing more than 50,000 adults on a variety of health topics, were recontacted in 2002 and interviewed by telephone about injection drug use, their own and partner's HIV serostatus, and sexual risk behaviors. RESULTS: Among 220 men who reported a primary partner, 86% [95% confidence interval (CI): 77-92] knew their primary partner's serostatus; 62% (95% CI, 52-70) of the 250 men who reported a secondary partner knew their most recent secondary partner's HIV serostatus. Knowledge of one's most recent secondary partner's HIV serostatus was inversely related to history of injecting recreational drugs (odds ratio, 0.22; P < 0.01), and reporting a primary partner in the past year (odds ratio, 0.37; P < 0.05). Two-fifths (41%) of HIV-positive men and three-fifths (62%) of HIV-negative men engaged in serosorting (serocordant unprotected anal intercourse) with their primary partners, whereas 33% HIV-positive men and 20% HIV-negative men did so with their most recent secondary partners. CONCLUSIONS: This population-based survey documented the extent to which MSM know their partners' serostatus and practice serosorting behaviors. The findings emphasize the need for studies to report serocordant and serodiscordant unprotected anal intercourse separately, as the former presents significant lower risk of HIV transmission.

The effect of venue sampling on estimates of HIV prevalence and sexual risk behaviors in men who have sex with men.

OBJECTIVE: The objective of this study was to investigate differences in HIV prevalence and sexual risk behaviors among men who have sex with men (MSM) according to their gay venue visit patterns. METHODS: In a cross-sectional survey, a population-based sample of men aged 18 to 64 years who self-identified as gay or bisexual were interviewed by telephone regarding their sexual behaviors, HIV serostatus, and gay venue visit patterns. RESULTS: A total of 398 men were recruited for the study. The results showed that frequent gay venue visitors were more likely to engage in high-risk sexual behaviors. Among gay venue attendees who visited different types of gay venues, men who visited sex clubs/bathhouses reported the highest rates of 5 or more male sexual partners and unprotected anal intercourse (UAI) with secondary partners (62.6% and 34.6%, respectively), gay bar/club attendees and cruisers reported higher rates of having sex with women (8.5% and 14.8%, respectively), and circuit party attendees reported the highest HIV prevalence (40.4%) and serodiscordant UAI (30.2%). CONCLUSIONS: MSM who visited different types of gay venues and with varied visit frequency showed marked differences in sexual risk behaviors, and the differences suggest the importance of weighting procedure to obtain unbiased estimates in venue-based studies.

HIV prevalence and sexual risk behaviors among men who have sex with men: results from a statewide population-based survey in California.

OBJECTIVES: To investigate HIV prevalence, sexual risk behaviors, and HIV testing among men who have sex with men (MSM) between 18 and 64 years old living in California. DESIGN: Cross-sectional study of a statewide population-based sample of MSM. METHODS: Using data from the 2001 California Health Interview Survey (CHIS 2001), 398 men who self-identified as gay or bisexual were recontacted and interviewed by telephone for a follow-up study in 2002. Study participants were interviewed regarding their demographic characteristics and sexual behavior, HIV testing history, and HIV infection status. Those who self-reported as HIV-negative or of unknown status were offered an HIV test using a home urine specimen collection kit. RESULTS: HIV prevalence among MSM in California was 19.1% (95% confidence interval [CI]: 12.8% to 25.3%) with higher rates seen among the following subgroups: high school or less education (40.4%), annual income less than dollar 20,000 (35.0%), or history of ever injecting recreational drugs (40.3%). Young age and Hispanic or African-American race/ethnicity were associated with higher proportions of risky sexual behavior and lower HIV testing rates. CONCLUSIONS: HIV prevalence among MSM living in California continues to be high across the whole state, and population-based studies are needed periodically to complement findings from surveys using other sampling designs.

Nonoxynol-9 spermicide for prevention of vaginally acquired HIV and other sexually transmitted infections: systematic review and meta-analysis of randomised controlled trials including more than 5000 women.

We aimed to determine the effectiveness of the vaginally administered spermicide nonoxynol-9 (N-9) among women for the prevention of HIV and other sexually transmitted infections (STIs). We did a systematic review of randomised controlled trials. Nine such trials including 5096 women, predominantly sex workers, comparing N-9 with placebo or no treatment, were included. Primary outcomes were new HIV infection, new episodes of various STIs, and genital lesions. Five trials included HIV and nine included STI outcomes, and all but one (2% of the data) contributed to the meta-analysis. Overall, relative risks of HIV infection (1.12, 95% confidence interval 0.88-1.42), gonorrhoea (0.91, 0.67-1.24), chlamydia (0.88, 0.77-1.01), cervical infection (1.01, 0.84-1.22), trichomoniasis (0.84, 0.69-1.02), bacterial vaginosis (0.88, 0.74-1.04) and candidiasis (0.97, 0.84-1.12) were not significantly different in the N-9 and placebo or no treatment groups. Genital lesions were more common in the N-9 group (1.18, 1.02-1.36). Our review has found no statistically significant reduction in risk of HIV and STIs, and the confidence intervals indicate that any protection that may exist is likely to be very small. There is some evidence of harm through genital lesions. N-9 cannot be recommended for HIV and STI prevention.
