Para alcançar esta meta, é preciso conhecer exatamente quais as condições e processos de cuidado que levam as mulheres a situações clínicas críticas e morte durante o ciclo gravídico-puerperal. Neste cenário, um grupo de pesquisadores implantou um projeto com objetivo de criar a rede nacional de cooperação científica para realizar vigilância, estimar frequência dos casos de near-miss maternos, realizar uma investigação multicêntrica sobre a qualidade dos cuidados das mulheres com complicações severas na gestação e conduzir uma avaliação multidimensional de um grupo selecionado destas mulheres (Rede Nacional de Vigilância de Morbidade Materna Grave - RNVMMG), composta de 27 serviços de referência em diferentes regiões do Brasil. Objetivo: avaliar a perspectiva dos profissionais sobre o impacto na qualidade dos cuidados oferecidos às mulheres com a participação do serviço na Rede Nacional de Vigilância de Morbidade Materna Grave (RNVMMG). Sujeitos e Métodos: Estudo multicêntrico com todos os participantes da RNVMMG nas 27 unidades obstétricas das cinco diferentes regiões geográficas do Brasil. Para o estudo, realizaram-se entrevistas com os coordenadores, pesquisadores e gestores de cada instituição, 6 e 12 meses após o término da coleta de dados da Rede. Os dados foram coletados a partir das entrevistas telefônicas gravadas, utilizando sistema digital NVIVO 9.0 ®, após consentimento informado verbal. Foi realizada análise qualitativa de conteúdo das respostas abertas das entrevistas e análise descritiva dos dados quantitativos. O conteúdo das respostas abertas foi submetido à análise temática, definindo-se as categorias e subcategorias emergentes dos discursos dos profissionais, segundo sua inserção institucional e na Rede. Resultados: Foram realizadas 122 entrevistas nas duas fases, incluindo pesquisadores e gestores dos serviços participantes, abrangendo 75,3% das entrevistas previstas, com maior participação dos gestores na 2ª fase. A maioria dos entrevistados considerou que a participação na RNVMMG mudou sua percepção e atitude diante da identificação dos casos de risco à morbidade/ mortalidade materna, ajudou a difundir os conhecimentos adquiridos no próprio serviço e tomar a conduta médica mais eficiente na condução desses casos. A divulgação científica dos resultados finais foi um fator determinante, em muitos serviços, para a discussão de mudanças de protocolo. Porém, não ficou evidente um impacto institucional duradouro. A necessidade de manter uma rede de vigilância morbidade materna grave foi salientada. Conclusão: Houve uma mudança significativa na capacidade dos profissionais que participaram da RNVMMG para identificar os casos, que se aprimorou ao longo do tempo. Os serviços participantes em sua maioria tiveram melhoria na qualidade dos cuidados oferecidos / Abstract: Background: Maternal death remains as a complex health problem and its reduction is the 5th Millennium Development Goal. To achieve this goal, countries need to know exactly what conditions lead to the death of women during pregnancy and childbirth. In this scenario, a group of researchers implemented a project to create a national network of scientific cooperation to surveillance, in order to know the frequency of near miss, to conduct a multicenter investigation on quality care of women with severe complications in pregnancy and to conduct a multidimensional assessment of a select group of these women (Brazilian Network for Surveillance of Severe Maternal Morbidity - BNSMM), with the participation of 27 centers in different regions of the country, Objective: To evaluate the perspective of professionals about the impact of the surveillance during the network study on the quality of care .Subjects and Methods: A multicenter study with 27 obstetric referral facilities in 5 different geographic regions of Brazil. For the study, researchers conducted a telephone interview with research coordinator, principal investigator and manager from each institution, six and 12 months after the end of the data collection from the surveillance study. Data was collected through interviews recorded using a digital system NVIVO® 9.0, after verbally authorized informed consent. Data analysis was performed by qualitative content analysis of open answers from the interviews and descriptive data analysis. The contents of the open answers were subjected to thematic analysis, defining the categories and subcategories of emerging discourses of professionals according to their insertion and institutional network. Results: We performed a total of 122 interviews in two phases including researchers and managers of the participating hospitals, covering 75.3% of the sample, with greater involvement of managers in the 2nd phase. Most of researchers felt that participation in BNSMM changed their perception and attitude towards the identification of cases with risk of severe maternal morbidity / mortality and helped to disseminate the knowledge acquired in the service itself and they considered that the medical management was more efficient in conducting these cases. Participants believe that the scientific publication of the final results was a determining factor to change practice. However, there was no evidently a lasting institutional impact. Participants emphasized need to maintain a network of severe maternal morbidity surveillance. Conclusion: There was a significant change in the ability of the professionals who participated in the RNVMMG to identify cases, which improved over time. Services participants mostly had improvement in quality of care offered / Doutorado / Saúde Materna e Perinatal / Doutora em Ciências da Saúde

O estudo dos casos de Near Miss (NM) é estratégico para identificar falhas no atendimento obstétrico. Em números absolutos, tanto MM quanto a ocorrência de eclâmpsia são eventos raros. Objetivo: avaliar os principais preditores de desfecho maternal grave (DMG: NM materno e MM) para eclâmpsia. Métodos: análise secundária de um estudo transversal, multicêntrico, incluindo 27 unidades obstétricas de referência de todas as cinco regiões do Brasil, entre 2009/2010. Foram identificados 426 casos de eclâmpsia e classificados de acordo com os resultados: DMG e não-DMG. As regiões brasileiras foram divididas em regiões de menor e maior renda e calculados os indicadores de cuidados obstétricos pela OMS. SPSS® e Stata® softwares foram utilizados para avaliar as características maternas, história clínica e obstétrica e o acesso aos serviços de saúde como preditores para a DMG, e correspondentes resultados perinatais, através do cálculo das razões prevalência (RP), respectivos intervalos de confiança de 95% (IC) e ainda aplicada à análise de regressão múltipla de Poisson (ajustada para o efeito cluster). Resultados: a prevalência e o índice de mortalidade por eclâmpsia em regiões de menor e maior renda foram de 0,8% / 0,2% e 8,1% / 22%, respectivamente. Dificuldades no acesso aos serviços de saúde: internação em UTI (RP ajustada 3,61, IC 95% 1,77-7,35) e monitorização inadequada (RP ajustada 2,31, IC 95% 1,48-3,59) foram associadas com DMG, também a morte perinatal foi maior neste grupo (RP ajustada 2,30; IC de 95% 1,45-3,65). Conclusão: a morbidade / mortalidade associada com eclâmpsia foi elevada no Brasil, especialmente nas regiões de baixa renda. A qualificação do atendimento à saúde materna e melhorias nos atendimentos das emergências são essenciais para aliviar a carga de eclâmpsia / Abstract: Background: Maternal mortality (MM) is a core indicator of disparities in women rights. Studying Near Miss cases is strategic to identify breakdowns in obstetrical care. In absolute numbers, both MM and the occurrence of eclampsia are rare events. We aim to assess the obstetric care indicators and main predictors for severe maternal outcome from eclampsia (SMO: maternal death plus maternal near miss). Methods: secondary analysis of a multicentre cross-sectional study, including 27 referral obstetric units from all five regions of Brazil, from 2009/2010. 426 cases of eclampsia were identified and classified according to outcomes: SMO and non-SMO. We divided Brazilian regions in lower and higher income regions and calculated the obstetric care indicators by WHO. SPSS® and Stata® softwares were used to assess the maternal characteristics, clinical and obstetrical history, access to health services as predictors for SMO, and correspondent perinatal outcomes, by calculating the prevalence ratios (PR), respective 95% confidence interval (CI) and also applying Poisson multiple regression analysis (adjusted for cluster effect). Results: prevalence and mortality index for eclampsia in lower and higher income regions were0.8%/ 0.2% and 8,1%/ 22%, respectively. Difficulties on access health care: ICU admission (adjPR 3.61; 95%CI 1.77-7.35) and inadequate monitoring (adjPR 2.31; 95%CI 1.48-3.59) were associated with SMO, also perinatal death was higher in this group (adjPR 2.30; 95%CI 1.45-3.65). Conclusions: morbidity/mortality associated with eclampsia were high in Brazil, especially in lower income regions. Qualifying maternal health and improvements in emergency care are essential to relieve the burden of eclampsia / Mestrado / Saúde Materna e Perinatal / Mestra em Ciências da Saúde

Sujeitos e métodos: a revisão foi realizada a partir da busca eletrônica de artigos publicados e indexados nas bases bibliográficas MedLine e SciELO, além da busca manual em periódico brasileiro e na lista de referências bibliográficas dos artigos identificados pelos unitermos ¿maternal near miss¿. Os artigos foram qualitativamente avaliados pelo tipo de desenho de estudo, procedência, disponibilidade de dados originais e tipo de critério utilizado para a definição de near miss. Foi ainda realizado um estudo descritivo em um centro terciário de referência à saúde da mulher, entre 01 de julho de 2003 e 30 de junho de 2004. De 2.929 mulheres que tiveram parto na instituição, foram identificados os casos de morbidade grave segundo critérios propostos por Mantel e Waterstone, através de visita diária às instalações da maternidade. A revisão dos prontuários e a coleta dos dados de interesse foram realizadas no momento da alta hospitalar. As principais medidas de efeito estudadas foram: a ocorrência de near miss e seus fatores determinantes primários, critério de identificação como near miss, tempo total de permanência hospitalar, tempo de permanência em UTI e número e tipos de procedimentos especiais realizados. Resultados: Foram incluídos na revisão 33 estudos da literatura, com uma razão média de near miss de 7,5/1000 partos. No centro de referência foram identificados 124 casos de near miss, correspondente a uma razão de 42/1000 partos, e ocorreram dois óbitos maternos. Foram realizados 126 procedimentos especiais, 102 deles realizados em mulheres admitidas na UTI para suporte intensivo (80,9%). O número médio de procedimentos especiais por mulher foi de 1,04 (±1,91) e os mais freqüentes foram a instalação de acesso venoso central, a realização de ecocardiografia e a ventilação artificial invasiva. A média de permanência hospitalar foi de 10,3 dias (±13,24). O tempo de permanência hospitalar e o número de procedimentos especiais foram significativamente maiores quando utilizados os critérios de Mantel. Conclusões: A incidência de near miss tende a ser maior nos países em desenvolvimento e quando utilizada a definição de disfunção orgânica. A incidência de near miss foi elevada e os critérios propostos por Mantel permitiram a identificação de um subgrupo de mulheres com manejo clínico mais complexo, considerando-se o tempo de permanência hospitalar e a demanda por procedimentos especiais. Os determinantes primários de morbidade materna grave foram coincidentes com as principais causa básicas conhecidas de morte materna / Abstract: Objectives: to perform a wide review of the international and national literature and to combine reported data on the occurrence of severe maternal morbidity (near miss) in several contexts; to evaluate the occurrence of near-miss in a tertiary Brazilian maternity, using different sets of criteria, to identify their primary determinants, their demand for care and the maternal and fetal outcomes. Methods: the review was performed through an electronic search of the published articles indexed in the bibliographic databases of MedLine and SciELO, besides a manual search in Brazilian journal and in the list of references of the articles identified through the uniterms ¿maternal near miss¿. The articles were qualitatively evaluated according to their study design, local, availability of original data and kind of criteria used for the definition of near miss. A descriptive study was also performed at a tertiary referral center for the women¿s health, between 1st. July 2003 to 30th. June 2004. From the total of 2929 women who delivered at the institution during the period, the cases of maternal near miss morbidity were identified through a daily visit in the wards of the maternity according to the criteria proposed by Mantel and by Waterstone. At the moment of hospital discharge a review of the clinical records and data collection were performed. The main outcome measures studied were the occurrence of near miss and their primary determinant factors, criteria for identification as a near miss case, total time of hospital stay, time of stay in ICU and number and kind of special procedures performed. Results: thirty three studies were identified and evaluated as adequate for inclusion in the review and the mean near miss ratio was 7.5/1000 deliveries. A total of 124 cases of near-miss were identified in the referral center, corresponding to a ratio of 42/1000 deliveries, and there were two maternal deaths. For these cases, 126 special procedures were performed, 102 of them among women admitted in ICU for intensive care (80.9%). The mean number of special procedures by each woman was 1.04 (±1.91) and the most frequent were central venous access, echocardiography and invasive mechanical ventilation. The mean total time of hospital stay was 10.3 days (±13.24). The total time of hospital stay and the number of special procedures were significantly higher when the criteria of Mantel were used. Conclusions: there is a trend of higher incidence of near miss in developing countries and when using the definition of organ dysfunction. The incidence of near miss was high and the criteria proposed by Mantel allowed the identification of a sub-group of women with a more complex clinical management, considering the total time of hospital stay and the demand for special procedures. The primary determinants of severe maternal morbidity were coincident with the main known basic causes of maternal death / Mestrado / Tocoginecologia / Mestre em Tocoginecologia

A prematuridade terapêutica tem papel importante nesse contexto, pois se estima que 20 a 40% dos partos prematuros ocorrem por indicação dos provedores de assistência obstétrica. Dessa forma, a redução dos partos prematuros terapêuticos adquire cada vez mais importância para o controle da taxa de prematuridade e da morbimortalidade neonatais. O conhecimento dos fatores relacionados ao parto prematuro terapêutico é ponto fundamental para atingir essa redução. Objetivos: Avaliar a ocorrência do parto prematuro terapêutico e seus fatores associados na população do Estudo Multicêntrico de Investigação em Prematuridade (EMIP). Métodos: Análise secundária do EMIP, um estudo brasileiro de caso-controle aninhado a um corte transversal multicêntrico. O estudo ocorreu em 20 hospitais de referência em 3 regiões do Brasil de abril de 2011 a julho de 2012 e realizou a vigilância de 33.740 partos nesse período. O principal desfecho a ser avaliado é a ocorrência de parto prematuro terapêutico, definido como o parto que ocorreu antes de 37 semanas e que foi indicado pela equipe de assistência devido uma condição materna ou fetal. O grupo controle foi composto pelas mulheres com parto a termo. Os partos prematuros foram categorizados, conforme recomendações da Organização Mundial da Saúde, em prematuro extremo, muito prematuros e pretermo moderado Uma quarta categoria de idade gestacional, contemplando apenas os prematuros tardios, também foi analisada. Variáveis relacionadas a características sociodemográficas, pôndero-estaturais e de estilo de vida maternos, características da assistência ao pré-natal e ao parto e sobre a presença de morbidade ou complicação durante a gravidez, parto ou puerpério foram avaliadas na análise de risco para parto prematuro terapêutico. Foi realizada uma análise bivariada para estimar o risco de parto prematuro terapêutico para cada e uma análise multivariada com regressão logística não condicional para obter os fatores independentemente associados ao desfecho. Resultados: O parto prematuro terapêutico foi responsável por 35,4% dos partos prematuros na amostra estudada. As síndromes hipertensivas, o descolamento prematuro de placenta e a diabetes foram as condições que mais frequentemente motivaram a resolução prematura da gravidez. A idade materna avançada, a hipertensão crônica, a obesidade e a gravidez múltipla foram as principais condições maternas relacionadas à ocorrência de parto prematuro terapêutico. Houve uma tentativa de tratamento da condição materna que motivou a resolução em mais de 50% dos casos e 74,5% das mulheres com parto entre 28 e 31 semanas receberam corticoterapia. A cesariana foi a via de parto mais frequente. A proporção de mortalidade neonatal, do Apgar do quinto minuto menor que sete e da admissão em unidade intensiva neonatal foi muito maior nos prematuros terapêuticos do que no termo, mesmo considerando os prematuros tardios. Conclusões: Os resultados do estudo corroboram com a crescente importância do parto prematuro terapêutico, devido sua prevalência e impacto nos resultados perinatais. A gravidez múltipla, idade materna avançada, a obesidade e a presença de morbidades pré-gestacionais são os fatores que requerem especial atenção nas estratégias de prevenção da prematuridade terapêutica / Abstract: Background: More than 15 million babies are born prematurely each year worldwide and its the leading cause of deaths in the neonatal period. Provider-initiated preterm birth (piPTB) plays an important role in this context because it is estimated that 20-40% of preterm births occur by indication of obstetric care providers. Thus, the reduction in piPTB rate acquires more importance to decrease the rate of prematurity and neonatal morbidity and mortality. Knowledge of the factors related to piPTB is a key factor to achieve this reduction. Objectives: To evaluate the occurrence of provider-initiated preterm birth and the associated factors in the Multicenter Study on Preterm Birth in Brazil (EMIP) population. Methods: Secondary analysis of EMIP, a Brazilian multicenter cross-sectional study plus a nested case-control. The study took place in 20 referral hospitals in 3 regions of Brazil from April 2011 to March 2012 and conducted surveillance of 33,740 deliveries in this period. The primary outcome to be evaluated is the occurrence of provider-initiated preterm birth, defined as birth that occurred before 37 weeks and was medically indicated due to maternal or foetal condition. The control group was composed of women with term delivery. Preterm birth was categorized into extremely premature, very premature and moderate preterm, according to the World Health Organization. Another category that includes only the late preterm was also evaluated. Maternal, socio-demographic, obstetrical, prenatal care, delivery and postnatal characteristics were assessed as factors associated with piPTB. A bivariate analysis to estimate the risk for piPTB and a multivariate analysis using unconditional logistic regression for the factors independently associated with piPTB was performed. Results: The therapeutic preterm labor accounted for 35.4% of premature births in the sample. Hypertensive disorders, placental abruption and diabetes were the main conditions related to pi-PTB indications. Advanced maternal age, chronic hypertension, obesity and multiple pregnancy were the main maternal conditions related to pi-PTB. There was an attempt to treat maternal condition that led to the resolution in over 50% of cases and 74.5% of women with birth between 28 and 31 weeks received corticosteroid therapy. Cesarean section was the most frequent mode of delivery. The proportion of neonatal mortality, Apgar score<7 at 5 minutes and NICU admission were much higher in provider-initiated preterm newborns than in term newborns, even considering the late preterms. Conclusions: The results of our study corroborate the increasing notability of provider-initiated preterm birth, due to its prevalence and impact on perinatal outcomes. Multiple pregnancies, advanced maternal age, obesity and the presence of pre-gestational morbidities are the main factors that require special attention in prematurity prevention strategies / Mestrado / Saúde Materna e Perinatal / Mestre em Ciências da Saúde

As razões de Condições Potencialmente Ameaçadoras da Vida (CPAV), Resultados Maternos Graves (RMG), Near Miss Materno (NMM), e Mortalidade Materna (MM) foram estimadas e estratificadas por estágio de transição obstétrica. Resultados: Dados de 314.623 mulheres incluídas neste estudo demonstram que a fecundidade das mulheres, indiretamente estimada pela paridade, foi maior nos países que estão em estágio menor da transição obstétrica, variando de uma média de 3,0 crianças por mulher no Estágio II para 1,8 crianças por mulher no Estágio IV. O nível de medicalização do nascimento nas instituições de saúde dos países participantes, avaliada pelas taxas de cesárea e de indução de trabalho de parto, tendeu a aumentar à medida que os estágios de transição obstétrica aumentam. No Estágio IV, as mulheres tiveram 2,4 vezes a taxa de cesáreas (15,3% no Estágio II e 36,7% no Estágio IV) e 2,6 vezes a taxa de indução de trabalho de parto (7,1% no Estágio II e 18,8% no Estágio IV) que as mulheres de países no Estágio II. À medida que os estágios da transição obstétrica aumentaram, a média de idade das primíparas também aumentou. A ocorrência de ruptura uterina apresentou uma tendência decrescente, caindo aproximadamente 5,2 vezes, de 178 para 34 casos para 100 000 nascidos vivos à medida que os países transicionaram do Estágio II para o Estágio IV. Conclusões: Esta análise corroborou o modelo da Transição Obstétrica utilizando um banco de dados de grande porte e multipaíses. O modelo da Transição Obstétrica pode justificar a individualização da estratégia de redução da mortalidade materna de acordo com os estágios da transição obstétrica de cada país / Abstract: Objectives: To test whether the proposed features of the Obstetric Transition Model¿a theoretical framework that may explain gradual changes that countries experience as they eliminate avoidable maternal mortality¿are observed in a large, multicountry, maternal and perinatal health database. Methods: This was a secondary analysis of a WHO cross-sectional study that collected information on all women who delivered in 359 health facilities in 29 countries in Africa, Asia, Latin America, and the Middle East, during a 2¿4-month period in 2010 ¿ 2011. The ratios of Potentially Life-threatening Conditions (PLTC), Severe Maternal Outcomes (SMO), Maternal Near Miss (MNM) and Maternal Death (MD) were estimated and stratified by stages of obstetric transition. Results: Data from 314 623 women showed that female fertility, indirectly estimated by parity, was higher in countries at a lower obstetric transition stage, ranging from a mean of 3 children in Stage II to 1.8 children in Stage IV. The level of medicalization in health facilities in participating countries, defined by the number of caesarean deliveries and number of labor inductions, tended to increase as the stage of obstetric transition increased. In Stage IV, women had 2.4 times the caesarean deliveries (15.3% in Stage II and 36.7% in Stage IV) and 2.6 times the labor inductions (7.1% in Stage II and 18.8% in Stage IV) than women in Stage II. As the stages of obstetric transition increased, the mean age of primiparous women also increased. The occurrence of uterine rupture had a decreasing trend, dropping by 5.2 times, from 178 to 34 cases per 100 000 live births, as a country transitioned from Stage II to IV. Conclusions: This analysis supports the concept of obstetric transition using multicountry data. The obstetric transition model could provide justification for customizing strategies for reducing maternal mortality according to a country¿s stage in the obstetric transition / Mestrado / Saúde Materna e Perinatal / Mestra em Ciências da Saúde

BACKGROUND: Rates of maternal mortality and severe maternal morbidity are higher in New York City (NYC) than nationally, with Black birthing people experiencing the worst maternal outcomes, followed by Latina/e and Asian/Pacific Islander birthing people. This study aimed to understand the barriers and facilitators to engaging in maternal self-care and maternal health care to support the design of a stakeholder- informed maternal community health worker (CHW) model in NYC. The study also identified key intervention components and strategies for adoption, implementation, and sustainability. METHODS: In-depth interviews were conducted with prenatal and postpartum people (N=38) from a large teaching hospital in Upper Manhattan serving a racially and ethnically diverse patient population and with a cross-section of professionals (N=15) delivering maternal health care. Interviews took place between November 2020 and August 2022. Thematic analyses were conducted to uncover findings to inform program vii design, with the Intervention Mapping framework guiding this process. RESULTS: Findings reveal a range of barriers and facilitators to maternal self-care and health care engagement. Barriers included lack of transportation and childcare, delayed introduction of resources by the health care team, lack of care continuity, and experience with and concerns about disrespectful or discriminatory care. Additional barriers from the COVID-19 pandemic included disruptions to social support networks, childcare, and health care experience. Facilitators included information and advice from family, friends, and social media, positive coping skills, and trusted relationships with obstetric providers. Prenatal and postpartum participants recommended program components that provide emotional and instrumental support, and viewed the CHW as a someone they can trust to provide support and advice. Maternal health professionals recommended patient education and skills-building, and a focus on patients with high-risk pregnancies and chronic conditions. Maternal health professionals also recommended early staff and patient buy-in, clear definition of the CHW role, strong supervisory structure, and external seed funding. CONCLUSION: A needs and assets assessment using the Intervention Mapping framework was critical to design a stakeholder-informed and evidence-based maternal community health worker model. These findings include lessons learned for similar health systems seeking to develop community-based care models to address maternal health inequities and improve outcomes. / 2026-01-03T00:00:00Z

Osteopathic Manipulative Treatment (OMT) has been used for more than 100 years to enhance the physiologic process of labor and delivery by normalizing pelvic structures and providing adequate blood supply to the uterus. Since maternal morbidity and mortality is a major health concern for developing countries, it was desirable to explore the benefits of OMT. After IRB approval by the Virginia College of Osteopathic Medicine and Virginia Tech, the research was conducted in Santo Domingo, Dominican Republic at Hospital Maternidad Nuestra Señora de la Altagracia to determine the relationship of OMT during labor and delivery on rates of cesarean section and perineal lacerations/ episiotomies. Qualifying candidates received the next sequentially numbered envelope with a randomized number assigning her to either the treatment or control group. Staff physicians at the hospital provided care to women in the control group according to their standard protocol. Four Osteopathic Physicians and one pre-doctoral OMM fellow performed OMT on women during the first and second stages of labor and performed their deliveries. There were 33 parturients in the OMT Treatment group and 32 in the control, for a total of 65 in the trial. The results of a logistic regression analysis using Wald criterion, with a statistical significance of alpha = 0.05, indicated treatment group reduction of rates of episiotomies in the primiparous (P = .04) and marginal significance in the combined primiparous and multiparous population (P = .05). The percentage of episiotomies in the primiparous treatment group was 35.29% and 75% in the control group. The percentage of episiotomies in the combined primiparous and multiparous groups were 15.15% in the treatment group and 37.5% in the control group. The cesarean rate for the treatment group was 9.09% and 18.75% for the control group (P = 0.098). The percentages of grade I & II perineal lacerations were 15.15% for the treatment group and 12.5% for the control group (P = 0.55) due to the extensive use of episiotomies in the control group. There were composite calculations made of the total number of parturients who had either a cesarean section, an episiotomy, or a perineal laceration so that overall maternal morbidity in each group could be compared. In the combined groups, there were fourteen total parturients (42.42%) who had undergone one of the three outcomes measures in the treatment group and twenty-one (65.63%) in the control group. This brings an odds ratio of 0.200 and a significant P value of 0.0235. Though cross-cultural issues made it difficult to perform the research as originally intended, there is evidence that Osteopathic Obstetrics provides benefit to parturients. A multi-institutional randomized controlled trial is proposed as the next step for the evaluation of OMT during labor and delivery. / Ph. D.

Aims: The aims of this thesis were to investigate the risk of severe maternal morbidity amongst women from different socioeconomic groups in the UK, explore why these differences exist and compare these findings to the setting in Australia. Methods: Three separate analyses were conducted. The first used UK Obstetric Surveillance System (UKOSS) data to assess the incidence and independent odds of severe maternal morbidity by socioeconomic group in the UK. The second analysis used quantitative and qualitative data from the 2010 UK National Maternity Survey (NMS) to explore the possible reasons for the difference in odds of morbidity between socioeconomic groups in the UK. The third analysis used data from the Victorian Perinatal Data Collection (VPDC) unit in Austra lia to assess the incidence and odds of severe maternal morbidity by socioeconomic group in Victoria. Results: The UKOSS analysis showed that compared with women from the highest socioeconomic group, women in the lowest 'unemployed' group had 1.22 (95%CI: 0.92 - 1.61) times greater odds associated with severe maternal morbidity. The NMS analysis demonstrated that independent of ethnicity, age and parity, women from the lowest socioeconomic quintiJe were 60% less likely to have had any antenatal care (aOR 0.40; 95%CI 0.18 - 0.87), 40% less likely to have been seen by a health professional prior to 12 weeks gestation (aOR 0.62; 95%CI 0.45 - 0.85) and 45% less likely to have had a postnatal check with their doctor (aOR 0.55; 95%CI 0.42 - 0.70) compared to women from the highest quintile. The Victorian analysis showed that women from the lowest socioeconomic group were 21% (aOR 1.21 ; 95% CI 1.00 - 1.47) more likely and that Aboriginal and Torres Strait Islander women were twice (aOR 2.02; 95%CI 1.32 - 3.09) as likely to experience severe morbidity. Discussion: The resu lts suggest that women from the lowest socioeconomic group in the UK and in Victoria have increased odds of severe maternal morbidity. Further research is needed into why these differences exist and efforts must be made to ensure that these women are appropriately prioritised in the future planning of maternity services provisio n in the UK and Australia.

Thesis (MSc)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: Background Caesarean section deliveries are the most common procedures performed by obstetricians in Zimbabwe. Surgical site infections (SSI) following caesarean section delivery result in increased hospital stay, treatment, cost, hospital readmission rates and related maternal morbidity and mortality. There is no national surveillance system for SSIs in Zimbabwe, however, information is available on number of cases of post-operative wound infection after caesarean section, but the denominator and definition used is not consistent. The objective of this study were develop and strengthen the surveillance system in Zimbabwe, to establish a clinical-based system in a setting with limited microbiological access, to measure post-operative SSI after caesarean section and to describe the associated risk factors and to determine whether feedback of SSI data has any effect on the surgical site infection incidence rate. Methodology This was a before and after study with two rolling cohort periods conducted at two Central hospitals in Harare, Zimbabwe. An Infection Prevention and Control (IPC) intervention was conducted in-between. During the pre-intervention period, baseline demographic and clinical data were collected using a structured questionnaire, and during the post-intervention period the impact of the interventions was measured. Convenience sampling was employed. Results A total of 290 women consented to participate in the study in the pre intervention period, 86.9% (n= 252) completed the 30-days post-operative follow-up and the incidence rate of SSI was 29.0% (n=73, 95% CI:23.4-35.0) Interventions developed included: training in Infection Prevention and Control for health workers; implementation of a protocol for cleaning surgical instruments; dissemination of information on post-operative wound management for the women. After implementation of the intervention, 314 women were recruited for the post-intervention, 92.3%(n= 290) completed the 30-day follow-up and there was a significant (p<0.001) reduction in the incidence rate of SSIs to 12.1 % (n=35, 95% CI: 8.3 -15.8) during this period. Development of SSI after caesarean section was found to be significantly associated with emergency surgery (p<0.001), surgical wound class IV (p=0.001) and shaving at home (p<0.001) at both pre- intervention and post-intervention periods. Stellenbosch University https://scholar.sun.ac.za iii Conclusion This study shows that caesarean section can be performed with low incidence of SSI if appropriate interventions such as training in IPC, adequate cleaning of equipment and education in wound-care for the mother are adhered to. It also demonstrated a simple surveillance data collection tool can be used on a wide scale in resource limited countries to assist policy makers with monitoring and evaluation of SSI rates as well as assessment of risk factors. / AFRIKAANSE OPSOMMING: Agtergrond Keisersnitte is die mees algemene prosedure wat uitgevoer word deur obstetriese dokters in Zimbabwe. Chirurgiese wond infeksies wat op keisersnitte volg lei tot verlengde hospitaal verblyf, behandeling, koste, heropname koerse en verwante moederlike morbiditeit en mortaliteit. Alhoewel daar geen nasionale waaktoesig sisteem vir chirurgiese wondinfeksies is nie, is informasie beskikbaar vir ‘n aantal gevalle wat post-operatiewe wondinfeksie na ‘n keisersnit onwikkel het, maar die noemer en definisie word inkonsekwent gebruik. Die doel van hierdie studie was om die waaktoesig sisteem in Zimbabwe te ontwikkel en te versterk, om ‘n klinies-gebasseerde sisteem te vestig in ‘n opset met beprekte mikrobiologiese toegang, om postoperatiewe chirurgiese wond infeksies na keisersnitte te meet en om die geassosieerde risikofaktore te beskryf en om vas te stel of terugvoering van chirurgiese wondinfeksie data enige effek op die infeksiekoerse na keisersnitverlossings gehad het. Metodologie Hierdie was ‘n voor-en-na studie met twee kohort periodes uitgevoer by twee sentrale hospitale in Harare, Zimbabwe. ‘n Infeksievoorkoming en –beheer intervensie was tussenin uitgevoer. Tydens die pre-intervensie periode was basislyn demografiese en kliniese data ingesamel deur middel van ‘n gestruktureerde vraeboog, en gedurende die post-intervensie fase was die impak van die intervensies gemeet. Gerieflikheidsteekproefneming was geimplementeer. Resultate ‘n Totaal van 290 vroue het toestemming verleen om aan die studie deel te neem in die pre-intervensie periode, waarvan 86.9% (n=252) die 30 day post-operatiewe opvolg voltooi het en die insidensiekoers van chirurgiese wondinfeksies was 29.0% (n=73, 95% CI:23.4-35.0) Intervensies wat onwikkel was het ingesluit: opleiding in Infeksie Voorkoming en -Beheer vir gesondheidswerkers; die implementering van ‘n protokol om chirurgiese instrumente skoon te maak; disseminering van informasie oor post-operatiewe wondhantering vir vroue. Na die implimentering van die intervensie was 314 vroue gewerf in die post-intervensie fase, waarvan 92.3% (n=290) die 30 dae opvolg voltooi het. Daar was ‘n beduidende (p<0.001) verlaging in die insidensiekoers van chirurgiese wondinfeksies na 12.1% (n=35, 95% CI: 8.3-15.8) gedurende hierdie periode. Stellenbosch University https://scholar.sun.ac.za v Daar was bevind dat chirurgiese wondinfeksies beduidend geassosieer was met noodchirurgie (p<0.001), chirurgiese wondklassifikasie IV (p=0.001) en skeer van hare by die huis (p<0.001) by beide die pre-intervensie en post-intervensie periodes. Gevolgtrekking Hierdie studie wys dat keisersnitte uitgevoer kan word met ‘n lae insidensie van chirurgiese wondinfeksies indien toepaslike intervensies, soos opleiding in infeksievoorkoming en beheer, voldoende skoonmaak van toerusting en opvoeding in wondsorg vir die moeders. Dit het ook aangedui dat ‘n eenvoudige data-insameling instrument op ‘n wye basis gebruik kan word in beperkte-hulpbron lande om beleidmakers te help met monitering en evaluering van chirurgiese wondinfeksie koerse, asook die assessering van risikofaktore.
