Factors influencing maternal death in Cambodia, Laos, Myanmar, and Vietnam countries: A systematic review.

BACKGROUND: A maternal mortality ratio is a sensitive indicator when comparing the overall maternal health between countries and its very high figure indicates the failure of maternal healthcare efforts. Cambodia, Laos, Myanmar, and Vietnam-CLMV countries are the low-income countries of the South-East Asia region where their maternal mortality ratios are disproportionately high. This systematic review aimed to summarize all possible factors influencing maternal mortality in CLMV countries. METHODS: This systematic review applied "The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Checklist (2020)", Three key phrases: "Maternal Mortality and Health Outcome", "Maternal Healthcare Interventions" and "CLMV Countries" were used for the literature search. 75 full-text papers were systematically selected from three databases (PubMed, Google Scholar and Hinari). Two stages of data analysis were descriptive analysis of the general information of the included papers and qualitative analysis of key findings. RESULTS: Poor family income, illiteracy, low education levels, living in poor households, and agricultural and unskilled manual job types of mothers contributed to insufficient antenatal care. Maternal factors like non-marital status and sex-associated work were highly associated with induced abortions while being rural women, ethnic minorities, poor maternal knowledge and attitudes, certain social and cultural beliefs and husbands' influences directly contributed to the limitations of maternal healthcare services. Maternal factors that made more contributions to poor maternal healthcare outcomes included lower quintiles of wealth index, maternal smoking and drinking behaviours, early and elderly age at marriage, over 35 years pregnancies, unfavourable birth history, gender-based violence experiences, multigravida and higher parity. Higher unmet needs and lower demands for maternal healthcare services occurred among women living far from healthcare facilities. Regarding the maternal healthcare workforce, the quality and number of healthcare providers, the development of healthcare infrastructures and human resource management policy appeared to be arguable. Concerning maternal healthcare service use, the provisions of mobile and outreach maternal healthcare services were inconvenient and limited. CONCLUSION: Low utilization rates were due to several supply-side constraints. The results will advance knowledge about maternal healthcare and mortality and provide a valuable summary to policymakers for developing policies and strategies promoting high-quality maternal healthcare.

[Regional inequalities in access to hospital birth in the state of Rio de Janeiro, Brazil: travel networks, distance, and time (2010-2019)]. / Desigualdades regionais no acesso ao parto hospitalar no Estado do Rio de Janeiro, Brasil: redes de deslocamento, distância e tempo (2010-2019).

Difficult access to birth care services is associated with infant and neonatal mortality and maternal morbidity and mortality. In this study, data from the Brazilian Unified National Health System (SUS) were used to map the evolution of geographic accessibility to hospital birth of usual risk in the state of Rio de Janeiro, Brazil, corresponding to 418,243 admissions in 2010-2011 and 2018-2019. Travel flows, distances traveled, and intermunicipal travel time between the pregnant women's municipality and hospital location were estimated. An increase from 15.9% to 21.5% was observed in the number of pregnant women who needed to travel. The distance traveled increased from 24.6 to 26km, and the travel time from 76.4 to 96.1 minutes, with high variation between Health Regions (HR). Pregnant women living in HR Central-South traveled more frequently (37.4-48.9%), and those living in the HRs Baía da Ilha Grande and Northwest traveled the largest distances (90.9-132.1km) and took more time to get to the hospital in 2018-2019 (96-137 minutes). The identification of municipalities that received pregnant women from many other municipalities and municipalities that treated a higher number of pregnant women (hubs and attraction poles, respectively) reflected the unavailability and disparities in access to services. Regional inequalities and reduced accessibility highlight the need to adapt supply to demand and review the distribution of birth care services in the state of Rio de Janeiro. This study contributes to research and planning on access to maternal and child health services and can be used as a reference study for other states in the country.

A dificuldade de acesso aos serviços de atenção ao parto está associada à mortalidade infantil e neonatal e à morbimortalidade materna. Neste estudo, dados do Sistema Único de Saúde (SUS) foram utilizados para mapear a evolução da acessibilidade geográfica ao parto hospitalar de risco habitual no Estado do Rio de Janeiro, Brasil, correspondentes a 418.243 internações nos biênios 2010-2011 e 2018-2019. Foram estimados os fluxos de deslocamento, as distâncias percorridas e o tempo de deslocamento intermunicipal entre o município de residência e de internação das gestantes. Houve um crescimento de 15,9% para 21,5% na proporção de gestantes que precisaram se deslocar. A distância percorrida aumentou de 24,6 para 26km, e o tempo de deslocamento de 76,4 para 96,1 minutos, com grande variação entre as Regiões de Saúde (RS). As gestantes residentes na RS Centro Sul se deslocaram mais frequentemente (37,4-48,9%), e as residentes nas RS Baía da Ilha Grande e Noroeste percorreram as maiores distâncias (90,9-132,1km) e levaram mais tempo para chegar ao hospital no último biênio (96-137 minutos). A identificação dos municípios que receberam gestantes de muitos outros municípios e daqueles que atenderam maior volume de gestantes (núcleos e polos de atração, respectivamente) refletiu a indisponibilidade e as disparidades no acesso aos serviços. As desigualdades regionais e a redução da acessibilidade alertam para a necessidade de adequar a oferta à demanda e de revisar a distribuição dos serviços de atenção ao parto no Rio de Janeiro. O estudo contribui para as pesquisas e o planejamento sobre o acesso a serviços de saúde materno-infantil, além de servir como referência para outros estados do país.

Objective: To analyze trends in sociodemographic inequalities in the access to and use of prenatal care in Baixada Litorânea, a region of the state of Rio de Janeiro, Brazil, 2000-2020. Methods: This was an ecological time-series study of the number of visits and adequacy of access to prenatal care. Absolute (differences) and relative (ratios) inequalities were calculated between extreme categories of variables; trends were estimated using joinpoint regression. Results: A total of 185,242 pregnant women were studied. A proportion of ≥ 7 visits increased annually by 2.4% (95%CI 1.1;3.7) between 2013 (54.4%) and 2020 (63.4%), stable for less than eight years of schooling. Adequacy of access increased 2.6% (95%CI 1.2;4.0) between 2014 and 2020, stable for women ≥ 35 years old and schooling ≥ 12 years. Absolute inequalities decreased (between 3.5% and 6.4%) for age and race/skin color, and relative inequalities decreased (between 7.7% and 20.0%) for all variables. Conclusion: Access and number of prenatal consultations increased, however, remained lower for adolescents, women with low level of schooling and those of Black and mixed race/skin color.

An assessment of the role of socio-economic, maternal and service utilization factors in increasing self-reported maternal complications in India.

BACKGROUND: Self-reported maternal complications are associated with maternal morbidity, deliveries by C-section, postpartum depression, and maternal death. Thus, it is necessary to examine the contribution of socio-demographic and maternal characteristics, as well as service utilization in the rising self-reporting of maternal complications (difficulty with daylight vision, convulsions, swelling of the legs, body or face, heavy vaginal bleeding or high fever) in India. The study aimed at examining the factors that have influenced the increasing prevalence of maternal complications between 2005-06 and 2015-16 in India. METHODS: Data from the two most recent rounds of the National Family Health Survey, which covered a sample of 36,850 and 190,898 women respectively who delivered in the last five years preceding the survey has been used. Logistic regression analysis was performed to carve out the factors which significantly contributed to maternal complications among women aged 15 - 49 years in India. With the help of the Fairlie decomposition technique, the study quantified the contribution of factors which influenced the changes in maternal complications in the period from 2005-06 to 2015-16. RESULTS: A significant increase was seen in the prevalence of maternal complications - from 43.6% to 53.7% between the years 2005-06 and 2015-16. About 21% of the increase could be explained by certain maternal, households level factors, service utilization and birth outcomes. For example, service utilization, in which 13% was attributed to the place of delivery and 6% to postnatal care, was the major contributor to the increase in maternal complications from 2005-06 to 2015-16). This was followed by individual-level factors like education (2%), body mass index (4%) and tobacco use,. It was also found that household-level factors like standard of living (-3.7%) and region (-1.4%), and birth weight contributed to the reduction of complications during the period. CONCLUSION: The increase in the prevalence of maternal complications in India could be attributed mainly attributed to increase in reporting behavior, an outcome of increased utilization of maternal healthcare services, and increase in BMI. However, reduced prevalence of maternal complications can be attributed to the decrease in the prevalence of low-birth-weight babies and tobacco use among women in India.

Wrong-Patient Orders in Obstetrics.

OBJECTIVE: To compare rates of wrong-patient orders among patients on obstetric units compared with reproductive-aged women admitted to medical-surgical units. METHODS: This was an observational study conducted in a large health system in New York between January 1, 2016, and December 31, 2018. The primary outcome was near-miss wrong-patient orders identified using the National Quality Forum-endorsed Wrong-Patient Retract-and-Reorder measure. All electronic orders placed for eligible patients during the study period were extracted retrospectively from the health system data warehouse, and the unit of analysis was the order session (consecutive orders placed by a single clinician for a patient within 60 minutes). Multilevel logistic regression models were used to estimate odds ratios (ORs) and 95% CIs comparing the probability of retract-and-reorder events in obstetric and medical-surgical units, overall, and in subgroups defined by clinician type and order timing. RESULTS: Overall, 1,329,463 order sessions were placed during the study period, including 676,643 obstetric order sessions (from 45,436 patients) and 652,820 medical-surgical order sessions (from 12,915 patients). The rate of 79.5 retract-and-reorder events per 100,000 order sessions in obstetric units was significantly higher than the rate in the general medical-surgical population of 42.3 per 100,000 order sessions (OR 1.98, 95% CI 1.64-2.39). The obstetric retract-and-reorder event rate was significantly higher for attending physicians and house staff compared with advanced practice clinicians. There were no significant differences in error rates between day and night shifts. CONCLUSION: Order errors occurred more frequently on obstetric units compared with medical-surgical units. Systems strategies shown to decrease these events in other high-risk specialties should be explored in obstetrics to render safer maternity care.

Perinatal psychosocial assessment of women of refugee background.

BACKGROUND: Women of refugee background may be particularly vulnerable to perinatal mental illness, possibly due to increased exposure to psychosocial stressors associated with their forced migration and post-resettlement adjustment. AIM: This study aimed to compare psychosocial risk factors reported by women of refugee background receiving maternity services at a public hospital, to those reported by Australian-born women in the same hospital. It further aimed to examine the referrals offered, and accepted, by the women of refugee background reporting psychosocial risk factors for perinatal mental illness. METHODS: A retrospective hospital record review was conducted to compare the antenatal and postnatal psychosocial risk factors of 100 women of refugee background and 100 Australian-born women who gave birth at a public hospital in Victoria between 1 July 2015 and 30 April 2016, and who had completed the Maternity Psychosocial Needs Assessment. FINDINGS: Women of refugee background were more likely than Australian-born women to report financial concerns and low social support at antenatal assessment, but were less likely to report prior mental health problems than Australian-born women at either assessment point. Both groups reported low rates of family violence compared to published prevalence rates. Of the women of refugee background assessed antenatally, 23% were offered referrals, with 52% take-up. Postnatally, 11.2% were offered referrals, with 93% take-up. DISCUSSION/CONCLUSION: This study showed elevated rates of psychosocial risk factors among women of refugee background, however, possible under-reporting of mental health problems and family violence raises questions regarding how to assess psychosocial risk factors with different cultural groups. Lower antenatal referral take-up suggests barriers to acceptance of referrals may exist during pregnancy.

Impact of Indonesia's national health insurance scheme on inequality in access to maternal health services: A propensity score matched analysis.

BACKGROUND: Reducing inequality in maternal, neonatal and infant mortality are key targets in the Sustainable Development Goals. This study is the first to evaluate the impact of Indonesia's national health insurance scheme, Jaminan Kesehatan Nasional (JKN), on access to maternal health services by sociodemographic status. METHODS: Using data from the 2017 Indonesia Demographic and Health Survey (IDHS) on women with live births in 2016-2017, we conducted propensity score matching (PSM) analysis to evaluate the association of JKN enrollment on the following maternal health care utilisation outcomes: (1) at least four antenatal care (ANC4+) visits; (2) ANC4+ visits and received essential components of ANC; (3) skilled birth attendance; (4) facility-based delivery; (5) post-natal care (PNC); and (6) PNC with skilled provider. Analyses were conducted at the national level and by economic subgroup and region of residence. Additionally, we investigated the potential negative impact of JKN on access to maternal health services among the uninsured population by looking at trends over time using data from the 2012 and 2017 IDHS. RESULTS: Of the 5429 women who had recently given birth, 61% were insured by JKN in 2017. After matching treated and untreated women on key sociodemographic characteristics, enrollment in JKN was associated with a higher prevalence of receiving ANC4+ visits (7.4%, 95% confidence interval (CI) = 4.8-9.39); ANC4+ visits and received essential components of ANC (5.6%, 95% CI = 3.3-7.9); skilled birth attendance (3.0%, 95% CI = 1.5-4.5; facility-based delivery (10.2%, 95% CI = 7.5-12.7); PNC (4.0%, 95% CI = 2.2-5.7); PNC with skilled provider (4.5%, 95% CI = 2.6-6.5). Effect sizes were larger among the poor and those living in less-developed areas, such as Eastern Indonesia and Sulawesi, except for at least ANC4+ and received clinical components. CONCLUSIONS: Expansion of health insurance coverage was associated with reductions in sociodemographic inequalities in access to maternal health services in Indonesia. However, large differences in utilisation persist across regions and by economic subgroup. Accelerating progress toward universal health coverage may reduce health inequalities in other low and middle-income countries.

Survey of Australian maternity hospitals to inform development and implementation of a stillbirth prevention 'bundle of care'.

BACKGROUND: 'Bundles of care' are being implemented to improve key practice gaps in perinatal care. As part of our development of a stillbirth prevention bundle, we consulted with Australian maternity care providers. OBJECTIVE: To gain the insights of Australian maternity care providers to inform the development and implementation of a bundle of care for stillbirth prevention. METHODS: A 2018 on-line survey of hospitals providing maternity services included 55 questions incorporating multiple choice, Likert items and open text. A senior clinician at each site completed the survey. The survey asked questions about practices related to fetal growth restriction, decreased fetal movements, smoking cessation, intrapartum fetal monitoring, maternal sleep position and perinatal mortality audit. The objectives were to assess which elements of care were most valued; best practice frequency; and, barriers and enablers to implementation. RESULTS: 227 hospitals were invited with 83 (37%) responding. All proposed elements were perceived as important. Hospitals were least likely to follow best practice recommendations "all the time" for smoking cessation support (<50%), risk assessment for fetal growth restriction (<40%) and advice on sleep position (<20%). Time constraints, absence of clear guidelines and lack of continuity of carer were recognised as barriers to implementation across care practices. CONCLUSIONS: Areas for practice improvement were evident. All elements of care were valued, with increasing awareness of safe sleeping position perceived as less important. There is strong support from maternity care providers across Australia for a bundle of care to reduce stillbirth.

Prenatal care in the Brazilian public health services / Assistência pré-natal na rede pública do Brasil

ABSTRACT OBJECTIVE To verify regional inequalities regarding access and quality of prenatal and birth care in Brazilian public health services and associated perinatal outcomes METHODS Birth in Brazil was a national hospital-based survey conducted between 2011 and 2012, which included 19,117 women with public-funded births. Regional differences in socio-demographic and obstetric characteristics, as well as differences in access and quality of prenatal and birth care were tested by the χ2 test. The following outcomes were assessed: spontaneous preterm birth, provider-initiated preterm birth, low birth weight, intrauterine growth restriction, Apgar in the 5th min < 8, neonatal and maternal near miss. Multiple and non-conditional logistic regressions were used for the analysis of the associated perinatal outcomes, with the results expressed in adjusted odds ratio and 95% confidence interval. RESULTS Regional inequalities regarding access and quality of prenatal and birth care among users of public services are still evident in Brazil. Pilgrimage for birth associated with all perinatal outcomes studied, except for intrauterine growth restriction. The odds ratios ranged between 1.48 (95%CI 1.23-1.78) for neonatal near miss and 1.62 (95%CI 1.27-2.06) for provider-initiated preterm birth. Among women with clinical or obstetric complications, pilgrimage for birth associated with provider-initiated preterm birth and with Apgar in the 5th min < 8, odds ratio of 1.98 (95%CI 1.49-2.65) and 2.19 (95%CI 1.31-3.68), respectively. Inadequacy of prenatal care associated with spontaneous preterm birth in both groups of women, with or without clinical or obstetric complications. CONCLUSION Improvements in the quality of prenatal care, appropriate coordination and comprehensive care at the time of birth have a potential to reduce prematurity rates and, consequently, infant morbidity and mortality rates in the country.

RESUMO OBJETIVO Verificar desigualdades regionais no acesso e na qualidade da atenção ao pré-natal e ao parto nos serviços públicos de saúde no Brasil e a sua associação com a saúde perinatal. MÉTODOS Nascer no Brasil foi uma pesquisa nacional de base hospitalar realizada entre 2011 e 2012, que incluiu 19.117 mulheres com pagamento público do parto. Diferenças regionais nas características sociodemográficas e obstétricas, bem como as diferenças no acesso e qualidade do pré-natal e parto foram testadas pelo teste do χ2. Foram avaliados os desfechos: prematuridade espontânea, prematuridade iniciada por intervenção obstétrica, baixo peso ao nascer, crescimento intrauterino restrito, Apgar no 5º min < 8, near miss neonatal e near miss materno. Para a análise dos desfechos perinatais associados, foram utilizadas regressões logísticas múltiplas e não condicionais, com resultados expressos em odds ratio ajustada e intervalo de confiança de 95%. RESULTADOS As desigualdades regionais ainda são evidentes no Brasil, no que diz respeito ao acesso e qualidade do atendimento pré-natal e ao parto entre as usuárias dos serviços públicos. A peregrinação para o parto se associou a todos os desfechos perinatais estudados, exceto para crescimento intrauterino restrito. As odds ratios variaram de 1,48 (IC95% 1,23-1,78) para near miss neonatal a 1,62 (IC95% 1,27-2,06) para prematuridade iniciada por intervenção obstétrica. Entre as mulheres com alguma complicação clínica ou obstétrica, a peregrinação se associou ainda mais com a prematuridade iniciada por intervenção e com Apgar no 5º min < 8, odds ratio de 1,98 (IC95% 1,49-2,65) e 2,19 (IC95% 1,31-3,68), respectivamente. A inadequação do pré-natal se associou à prematuridade espontânea em ambos os grupos de mulheres CONCLUSÃO Melhorar a qualidade do pré-natal, a coordenação e a integralidade do atendimento no momento do parto têm um impacto potencial nas taxas de prematuridade e, consequentemente, na redução das taxas de morbimortalidade infantil no país.

Tracking pregnant women displacements in Sao Paulo, Brazil: a complex systems approach to regionalization through the emergence of patterns.

BACKGROUND: The healthcare system can be understood as the dynamic result of the interaction of hospitals, patients, providers, and government configuring a complex network of reciprocal influences. In order to better understand such a complex system, the analysis must include characteristics that are feasible to be studied in order to redesign its functioning. The analysis of the emergent patterns of pregnant women flows crossing municipal borders for birth-related hospitalizations in a region of São Paulo, Brazil, allowed to examine the functionality of the regional division in the state using a complex systems approach and to propose answers to the dilemma of concentration vs. distribution of maternal care regional services in the context of the Brazilian Unified Health System (SUS). METHODS: Cross-sectional research of the areas of influence of hospitals using spatial interaction methods, recording the points of origin and destination of the patients and exploring the emergent patterns of displacement. RESULTS: The resulting functional region is broader than the limits established in the legal provisions, verifying that 85% of patients move to hospitals with high technology to perform normal deliveries and cesarean sections. The region has high independence rates and behaves as a "service exporter." Patients going to centrally located hospitals travel twice as long as patients who receive care in other municipalities even when the patients' conditions do not demand technologically sophisticated services. The effects of regulation and the agents' preferences reinforce the tendency to refer patients to centrally located hospitals. CONCLUSIONS: Displacement of patients during delivery may affect indicators of maternal and perinatal health. The emergent pattern of movements allowed examining the contradiction between wider deployments of services versus concentration of highly specialized resources in a few places. The study shows the potential of this type of analysis applied to other type of patients' flows, such as cancer or specialized surgery, as tools to guide the regionalization of the Brazilian Health System.

Potential Effects of Regionalized Maternity Care on U.S. Hospitals.

OBJECTIVE: To examine the current patterns of care for women at high risk for delivery-related morbidity to inform discussions about the feasibility of this regionalized approach. METHODS: We performed a cross-sectional study and linked 2014 American Hospital Association survey and State Inpatient Database data from seven representative states. We used American Hospital Association-reported hospital characteristics and State Inpatient Database procedure codes to assign a level of maternal care to each hospital. We then assigned each patient to a minimum required level of maternal care (I-IV) based on maternal comorbidities captured in the State Inpatient Database. Our outcome was delivery at a hospital with an inappropriately low level of maternal care. Comorbidities associated with delivery at an inappropriate hospital were assessed using descriptive statistics. RESULTS: The analysis included 845,545 deliveries occurring at 556 hospitals. The majority of women had risk factors appropriate for delivery at level I or II hospitals (85.1% and 12.6%, respectively). A small fraction (2.4%) of women at high risk for maternal morbidity warranted delivery in level III or IV hospitals. The majority (97.6%) of women delivered at a hospital with an appropriate level of maternal care, with only 2.4% of women delivering at a hospital with an inappropriate level of maternal care. However, 43.4% of the 19,988 high-risk patients warranting delivery at level III or IV hospitals delivered at level I or II hospitals. Women with comorbidities likely to benefit from specialized care (eg, maternal cardiac disease, placenta previa with prior uterine surgery) had high rates of delivery at hospitals with an inappropriate level of maternal care (68.2% and 37.7%, respectively). CONCLUSION: Though only 2.41% of deliveries occurred at hospitals with an inappropriate level of maternal care, a substantial fraction of women at risk for maternal morbidity delivered at hospitals potentially unequipped with resources to manage their needs. Promoting triage of high-risk patients to hospitals optimized to provide risk-appropriate care may improve maternal outcomes with minimal effect on most deliveries.

What components of smoking cessation care during pregnancy are implemented by health providers? A systematic review and meta-analysis.

BACKGROUND: Pregnancy is an opportunity for health providers to support women to stop smoking. OBJECTIVES: Identify the pooled prevalence for health providers in providing components of smoking cessation care to women who smoke during pregnancy. DESIGN: A systematic review synthesising original articles that reported on (1) prevalence of health providers' performing the 5As ('Ask', 'Advise', 'Assess', 'Assist', 'Arrange'), prescribing nicotine replacement therapy (NRT) and (2) factors associated with smoking cessation care. DATA SOURCES: MEDLINE, EMBASE, CINAHL and PsycINFO databases searched using 'smoking', 'pregnancy' and 'health provider practices'. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Studies included any design except interventions (self-report, audit, observed consultations and women's reports), in English, with no date restriction, up to June 2017. PARTICIPANTS: Health providers of any profession. DATA EXTRACTION, APPRAISAL AND ANALYSIS: Data were extracted, then appraised with the Hawker tool. Meta-analyses pooled percentages for performing each of the 5As and prescribing NRT, using, for example, 'often/always' and 'always/all'. Meta-regressions were performed of 5As for 'often/always'. RESULTS: Of 3933 papers, 54 were included (n=29 225 participants): 33 for meta-analysis. Health providers included general practitioners, obstetricians, midwives and others from 10 countries. Pooled percentages of studies reporting practices 'often/always' were: 'Ask' (n=9) 91.6% (95% CI 88.2% to 95%); 'Advise' (n=7) 90% (95% CI 72.5% to 99.3%), 'Assess' (n=3) 79.2% (95% CI 76.5% to 81.8%), 'Assist (cessation support)' (n=5) 59.1% (95% CI 56% to 62.2%), 'Arrange (referral)' (n=6) 33.3% (95% CI 20.4% to 46.2%) and 'prescribing NRT' (n=6) 25.4% (95% CI 12.8% to 38%). Heterogeneity (I2) was 95.9%-99.1%. Meta-regressions for 'Arrange' were significant for year (p=0.013) and country (p=0.037). CONCLUSIONS: Health providers 'Ask', 'Advise' and 'Assess' most pregnant women about smoking. 'Assist', 'Arrange' and 'prescribing NRT' are reported at lower rates: strategies to improve these should be considered. PROSPERO REGISTRATION NUMBER: CRD42015029989.

Factors that impact the timely treatment of obstetric fistulas in Malawi: The perspective of health care providers.

BACKGROUND: In sub-Saharan African countries, women face a high risk of obstetric fistulas. In Malawi, the prevalence rate is 1 per 1000 women. Studies suggest that several obstacles exist that prevent obstetric fistula patients from getting timely treatment for their condition. AIM: The aim of this article was to find out the factors that delay the timely treatment of obstetric fistula patients at Malawian hospitals. SETTING: The study was conducted at the Queen Elizabeth Central Hospital, a referral hospital, situated in Blantyre, Malawi, and the findings have been generalised to all the hospitals in Malawi. METHODS: An exploratory case study, employing key interview questions, was used to provide insights into why there are delays in providing treatment and care for fistula patients. Purposive sampling technique was used to identify study respondents. Key informant interviews were conducted with 16 health care personnel at a hospital in Malawi. RESULTS: The presence of numerous cases of complicated obstetric fistula cases overwhelms the health care system in Malawi. In addition, the severe shortage of staff, lack of obstetric fistula surgery training, low staff morale, inadequate infrastructure or equipment and water scarcity in the city of Blantyre contribute towards delayed treatment of fistulas at the hospitals. CONCLUSION: The presence of numerous cases of obstetric fistulas is overwhelming health services, and hence there is a need for devising and implementing health policies that will motivate Malawian health personnel to undertake obstetric fistula surgery and care.

Including ultrasound scans in antenatal care in low-resource settings: Considering the complementarity of obstetric ultrasound screening and maternity waiting homes in strengthening referral systems in low-resource, rural settings.

Recent World Health Organization (WHO) antenatal care recommendations include an ultrasound scan as a part of routine antenatal care. The First Look Study, referenced in the WHO recommendation, subsequently shows that the routine use of ultrasound during antenatal care in rural, low-income settings did not improve maternal, fetal or neonatal mortality, nor did it increase women's use of antenatal care or the rate of hospital births. This article reviews the First Look Study, reconsidering the assumptions upon which it was built in light of these results, a supplemental descriptive study of interviews with patients and sonographers that participated in the First Look study intervention, and a review of the literature. Two themes surface from this review. The first is that focused emphasis on building the pregnancy risk screening skills of rural primary health care personnel may not lead to adaptations in referral hospital processes that could benefit the patient accordingly. The second is that agency to improve the quality of patient reception at referral hospitals may need to be manufactured for obstetric ultrasound screening, or remote pregnancy risk screening more generally, to have the desired impact. Stemming from the literature, this article goes on to examine the potential for complementarity between obstetric ultrasound screening and another approach encouraged by the WHO, the maternity waiting home. Each approach may address existing shortcomings in how the other is currently understood. This paper concludes by proposing a path toward developing and testing such a hybrid approach.

Factors associated with choice of antenatal, delivery and postnatal services between HIV positive and HIV negative women in Zambia.

BACKGROUND: Previous research has shown that developing countries account for the majority of maternal deaths around the world. Relatively high maternal mortality in developing countries has been linked to high HIV prevalence rates in these countries. Several studies have shown that women living with HIV are more vulnerable and are thus more likely to die during maternity than those who are not. Although there has been increased focus on this subject in contemporary research, the relationship between HIV status and maternal-care-utilization is not very well understood. It is not clear whether factors associated with professional maternal care utilization during antenatal, delivery and postnatal periods are similar for HIV positive and HIV negative women. It is also not known whether being HIV positive has an impact on the choice of care (professional care or traditional birth attendants). Thus the aim of this study is to investigate the differences in factors affecting choice of care during antenatal, delivery and postnatal periods between HIV positive and HIV negative women. We also investigate the effect of HIV positive status on choice of care. METHODS: By using the 2013-2014 Zambia Demographic Health Survey Data (ZDHS), we performed two different quantitative analyses. a) Regression analysis: to identify and compare factors associated with the likelihood of utilizing professional care during antenatal, at birth and postnatal periods between HIV positive and HIV negative women. b) Propensity score matching: to investigate the effect of being HIV positive on the choice of care (Professional care or TBAs). RESULTS: Our results show that reasons for choosing professional care during antenatal, at birth, and postnatal periods are the same for both HIV positive and HIV negative women. Further, we also showed that although the probability of utilizing professional care is slightly higher for HIV positive women, the difference is negligible. CONCLUSION: We demonstrated that in Zambia, utilization of professional care among HIV positive women is not particularly high. We also demonstrate that although institutional care is desirable and an ideal solution for HIV positive women, insisting on institutional care when the health facilities lack adequate trained personnel, drugs, and equipment is counterproductive.

Prevent Mother-to-Child Transmission (PMTCT) Programs and Enhancement of Maternal Healthcare Infrastructure to Improve Early Detection of Maternal Syphilis in Shanghai, China.

This study aimed to compare the screening and diagnosis of maternal syphilis in Shanghai between the national and municipal prevent mother-to-child transmission (PMTCT) of syphilis policies, and then to assess whether PMTCT programs and enhancing healthcare infrastructure could bring about an early detection of maternal syphilis. Detection of maternal syphilis was initiated in 2001 and then scaled-up in 2011 along with the enhancement of antenatal healthcare infrastructure. The initial five-year periods of municipal and national PMTCT policies were defined as the "exploring period" (2002⁻2006) and the "comprehensive period" (2011⁻2015). The demographic and gestational weeks (GW) of syphilis screening and diagnosis were analyzed to identify the factors affecting early detection. During the study period, maternal syphilis screening increased from 83,718 in 2002 to 243,432 in 2015. Of the 1,894,062 pregnant women screened, 1526 and 2714 participants were diagnosed with maternal syphilis in 2002⁻2006 and 2011⁻2015, respectively. The average age of diagnosis was 28.36 years and non-residents accounted for 71.1%. In the comprehensive period, more women received early syphilis screening (14.0% vs. 10.8%) and diagnosis (13.3% vs. 7.3%) within 12 GWs compared with the exploring period. Significantly, early detection grew during 2011⁻2015, which was not seen in the exploring period. Multivariate analysis revealed a greater possibility for infected women to be diagnosed within 16 GWs (OR = 2.76) in the comprehensive period, but those who were non-residents and unemployed were less likely to receive early detection. In conclusion, early detection of maternal syphilis has been remarkably improved. More emphasis is required on the development of pro-vulnerable policies and the implementation of tailored health education to improve the accessibility of routine antenatal care and awareness of syphilis prevention.

Experiencias de mujeres sobrevivientes a morbilidad materna extrema en México, un estudio cualitativo desde el modelo de las tres demoras / Experiences of survivors of maternal near miss in Mexico: a qualitative study based on the three delays model / Experiências de mulheres sobreviventes à morbidade materna extrema em México: um estudo qualitativo partindo do modelo das três demoras

Resumen: El objetivo fue analizar las experiencias de sobrevivientes de morbilidad materna extrema, para desde el enfoque de las tres demoras, identificar los determinantes que obstaculizan este proceso en el estado de San Luis Potosí, México. Durante 2016-2017, se realizó un estudio cualitativo con 27 mujeres que vivieron un evento de este tipo entre 2014 y 2016 en hospitales públicos. Las informantes fueron seleccionadas mediante muestreo teórico y entrevistadas en sus domicilios. El análisis de datos se realizó desde la propuesta de teoría fundamentada de Strauss & Corbin, las categorías asociadas con la primera demora fueron: (1) oportunidades pérdidas para la identificación de morbilidad materna extrema, (2) temor de comunicar el malestar frente a la descalificación, (3) entre el miedo y la fe en que algo superior resolverá, (4) desarrollo de la percepción del riesgo obstétrico. Con la segunda demora: (1) falta de ordenamiento urbano para el traslado, (2) ausencia de regulación de costos del traslado, (3) falta de claridad sobre los itinerarios y rutas críticas para acceder a la atención, (4) coordinación institucional para el traslado oportuno; y finalmente con la tercera: (1) rechazo institucional, (2) deficiencias de infraestructura, personal y equipo, y (3) entre la experiencia y la falta de ella del personal de salud. Las experiencias compartidas evidencian retos en materia de política pública y trabajo intersectorial para mejorar los resultados en materia de morbilidad materna extrema.

Abstract: The objectives were to analyze the experiences of survivors of maternal near miss based on the three delays model and to identify the obstacles to this process in the state of San Luis Potosí, Mexico. In 2016-2017, a qualitative study was performed with 27 women who had experienced maternal near miss in public hospitals between 2014 and 2016. The informants were selected with theoretical sampling and interviewed at their homes. Data analysis was based on the theoretical framework proposed by Strauss & Corbin. The categories associated with the first delay were: (1) missed opportunities for identification of maternal near miss; (2) failure of the women to voice their symptoms out of fear of reprimand; (3) dilemma between fear and the faith that a higher power will solve the problem; and (4) development of the perception of obstetric risk. The second delay involved: (1) lack of urban transportation infrastructure to access healthcare services; (2) lack of regulation of transportation costs; (3) lack of clarity on itineraries and critical routes to access care; and (4) lack institutional coordination for timely transportation. The third delay involved: (1) institutional refusal of care; (2) deficient infrastructure, personnel, and equipment; and (3) lack of expertise and experience in the healthcare personnel. The shared experiences reveal challenges for public policies and inter-sector work to improve the results in maternal near miss.

Maternal health training priorities for nursing and allied health workers in Colombia, Honduras, and Nicaragua / Prioridades de capacitación en el ámbito de la salud materna para el personal de enfermería y otros trabajadores de salud en Colombia, Honduras y Nicaragua / Prioridades em formação em saúde materna para profissionais de enfermagem e outros profissionais da saúde na Colômbia, Honduras e Nicarágua

ABSTRACT Objective To assess maternal health training priorities for primary care human resources for health (HRH) in nursing and allied health workers in Colombia, Honduras, and Nicaragua, to inform maternal care HRH strategic planning efforts. Methods This Washington, D.C.-based study utilized cross-sectional survey methodology to collect country-level data. From October 2016 to March 2017, a needs assessment tool was developed by the Pan American Health Organization/World Health Organization (PAHO/WHO) and PAHO/WHO Collaborating Centers. Data collection was completed by PAHO/WHO country offices, in collaboration with national health authorities and other high-level government personnel. The collected data included information on the composition, capacities, and training priorities of traditional birth attendants (TBAs), community health workers (CHWs), registered nurses (RNs), and auxiliary nurses in the three study countries; the findings were summarized in a report. Results Data on the health workforce composition in the three countries indicated reliance on HRH with low levels of education and training, with limited integration of TBAs. In all three countries, management of obstetric emergencies was a training priority for RNs, and identification of danger signs was a priority for CHWs and TBAs. Training priorities for auxiliary nurses varied widely across the three countries and included health promotion, preconception and prenatal care, and obstetric emergencies. There was also a wide range in the total number of HRH across the three countries. Conclusions Reliance on health workers with low levels of training is concerning but can be mitigated through in-service training. Training priorities are consistent with the major causes of maternal mortality, and Latin America and Caribbean region training programs show promise for improving quality of care. In the long term, planning for maternal care HRH should seek to increase the concentration of health professionals that are more highly skilled.

RESUMEN Objetivo Evaluar las prioridades de capacitación en el ámbito de la salud materna de los recursos humanos de enfermería y otros trabajadores de atención primaria en Colombia, Honduras y Nicaragua, y fundamentar los esfuerzos de planificación estratégica de los recursos humanos para la salud dedicados a la atención materna. Métodos En este estudio, con sede en Washington, D. C., se empleó una metodología de encuesta transversal para recopilar datos a nivel de país. Entre los meses de octubre del 2016 y marzo del 2017, la Organización Panamericana de la Salud/Organización Mundial de la Salud (OPS/OMS) y sus centros colaboradores elaboraron una herramienta para la evaluación de las necesidades. Las representaciones de la OPS/OMS, en colaboración con las autoridades nacionales de salud y otros funcionarios gubernamentales de alto nivel, realizaron la recopilación de datos. Los datos reunidos incluyeron información sobre la composición, las aptitudes y las prioridades de capacitación de las parteras tradicionales, los agentes comunitarios de salud, las enfermeras tituladas y las enfermeras auxiliares en los tres países del estudio. Los resultados se resumieron en un informe. Resultados Los datos sobre la composición del personal de salud en los tres países indicaron que se depende de recursos humanos para la salud que presentan escasos niveles de educación y formación, y que la integración de las parteras tradicionales es limitada. En los tres países, el tratamiento de las urgencias obstétricas constituyó una prioridad de capacitación para las enfermeras tituladas, y la detección de los signos de peligro fue una prioridad en el caso de los agentes comunitarios de salud y las parteras tradicionales. Las prioridades de formación para las enfermeras auxiliares variaron sustancialmente entre los tres países y entrañaron la promoción de la salud, la atención pregestacional y prenatal, y las urgencias obstétricas. Asimismo, el número total de recursos humanos para la salud varió considerablemente entre los países. Conclusiones Depender de personal de salud de escaso nivel formativo es motivo de preocupación, si bien la capacitación en el servicio puede mitigar este problema. Las prioridades de capacitación están en consonancia con las principales causas de mortalidad materna y los programas formativos de América Latina y el Caribe resultan prometedores para mejorar la calidad de la atención. A largo plazo, la planificación de los recursos humanos para la salud dedicados a la atención materna deberá procurar aumentar la concentración de profesionales de salud más capacitados.

RESUMO Objetivo Avaliar as prioridades de formação em saúde materna dos recursos humanos na área de atenção primária à saúde entre profissionais de enfermagem e outros profissionais da saúde na Colômbia, Honduras e Nicarágua, a fim de subsidiar os esforços de planejamento estratégico de recursos humanos para saúde materna. Métodos Foi conduzido um estudo transversal, sediado em Washington, D.C., para coletar dados ao nível nacional. Uma ferramenta de avaliação das necessidades foi desenvolvida, de outubro de 2016 a março de 2017, pela Organização Pan-Americana da Saúde/Organização Mundial da Saúde (OPAS/OMS) e Centros Colaboradores da OPAS/OMS. A coleta de dados foi concluída pelas representações da OPAS/OMS nos países, em colaboração com autoridades sanitárias nacionais e pessoal de alto escalão do governo. Foram coletados dados sobre a composição, as competências e as prioridades de formação de parteiras tradicionais, agentes comunitários de saúde, enfermeiros licenciados e assistentes de enfermagem nos três países de estudo. Os resultados foram compilados em um relatório. Resultados Os dados relativos à composição da força de trabalho em saúde nos três países indicaram que eles contam com pessoal com baixo nível de instrução e formação, com integração limitada das parteiras tradicionais. Observou-se, nos três países, que a atuação em emergências obstétricas era uma prioridade de formação para enfermeiros licenciados e a identificação de sinais de perigo era uma prioridade para agentes comunitários de saúde e parteiras tradicionais. As prioridades de formação para os assistentes de enfermagem foram bastante distintas entre os países: promoção da saúde, cuidados pré-concepcionais e assistência pré-natal e emergências obstétricas. O número total de recursos humanos para a saúde também variou nos três países. Conclusões É motivo de preocupação ter de contar com profissionais da saúde com baixo nível de formação, porém este problema pode ser reduzido com a capacitação no próprio serviço. As prioridades de formação nos países estudados são condizentes com as principais causas de mortalidade materna e os programas de formação profissional da Região da América Latina e Caribe têm potencial para melhorar a qualidade da atenção. O planejamento dos recursos humanos para saúde materna deve visar a longo prazo aumentar a concentração de profissionais que são mais capacitados.

Periconceptional folic acid supplementation and sex difference in prevention of neural tube defects and their subtypes in China: results from a large prospective cohort study.

BACKGROUND: Folic acid (FA) supplementation is known to prevent neural tube defects (NTDs). We examined whether this preventive effect differs by the sex of the infant. METHODS: Data were gathered from a large population-based cohort study in China that evaluated the effects of FA supplementation on NTDs. All births at 20 complete gestational weeks, including live births, stillbirths, and pregnancy terminations, and all NTDs, regardless of gestational age, were recorded. In a northern China province, a total of 30,801 singleton live births to women whose use of FA supplements during the first trimester was known at the time were included in the study. The birth prevalence of NTDs was classified by sex, subtype, and maternal FA supplementation. Male to female rate ratios [RR] and their 95% confidence intervals [CI] were calculated. RESULTS: A total of 106 NTDs cases were recorded. The overall prevalence of NTDs was 2.5‰ among males and 4.4‰ among females; NTDs were less prevalent among males than among females (RR, 0.58; 95% CI, 0.54-0.63). There was a higher prevalence of anencephaly (RR, 0.34; 95% CI, 0.27-0.43) and spina bifida (RR, 0.73; 95% CI, 0.63-0.84) among females. However, FA supplementation led to significantly greater decreases in the rates of anencephaly (4.8‰) and total NTDs (7.6‰) in females than in males (1.6‰ and 2.8‰, respectively). CONCLUSIONS: FA supplementation successfully reduces the prevalence of NTDs in both male and female infants, although we found a significantly greater decrease in anencephaly and total NTDs in females than in males. How the protective effects of FA supplementation affect the sexes differently needs to be studied further.
