Development of a new definition of maternal near miss based on organ dysfunction in Latin America and the Caribbean: A prospective multicenter cohort study.

BACKGROUND: There has been debate over whether the existing World Health Organization (WHO) criteria accurately represent the severity of maternal near misses. OBJECTIVE: This study assessed the diagnostic accuracy of two WHO clinical and laboratory organ dysfunction markers for determining the best cutoff values in a Latin American setting. METHODS: A prospective multicenter cohort study was conducted in five Latin American countries. Patients with severe maternal complications were followed up from admission to discharge. Organ dysfunction was determined using clinical and laboratory data, and participants were classified according to severe maternal outcomes. This study compares the diagnostic criteria of Latin American Centre for Perinatology, Network for Adverse Maternal Outcomes (CLAP/NAMO) to WHO standards. RESULTS: Of the 698 women studied, 15.2% had severe maternal outcomes. Most measured variables showed significant differences between individuals with and without severe outcomes (all P-values <0.05). Alternative cutoff values suggested by CLAP/NAMOs include pH ≤7.40, lactate ≥2.3 mmol/L, respiratory rate ≥ 24 bpm, oxygen saturation ≤ 96%, PaO2/FiO2 ≤ 342 mmHg, platelet count ≤189 × 109 × mm3, serum creatinine ≥0.8 mg/dL, and total bilirubin ≥0.67 mg/dL. No significant differences were found when comparing the diagnostic performance of the CLAP/NAMO criteria to that of the WHO standards. CONCLUSION: The CLAP/NAMO values were comparable to the WHO maternal near-miss criteria, indicating that the WHO standards might not be superior in this population. These findings suggest that maternal near-miss thresholds can be adapted regionally, improving the identification and management of severe maternal complications in Latin America.

What's the CATCH? A Participatory Learning Model for Case Review Rounds to Support a Culture of Safety and Quality Improvement in Pediatric Hospital Medicine.

OBJECTIVE: To evaluate the effectiveness of a new model, Case Analysis and Translation to Care in Hospital (CATCH), for the review of pediatric inpatient cases when an adverse event or "close call" had occurred. STUDY DESIGN: The curricular intervention consisted of an introductory podcast/workshop, mentorship of presenters, and monthly CATCH rounds over 16 months. The study was conducted with 22 pediatricians at a single tertiary care center. Intervention assessment occurred using participant surveys at multiple intervals: pre/post the intervention, presenter experience (post), physicians involved and mentors experience (post), and after each CATCH session. Paired t-tests and thematic analysis were used to analyze data. Time required to support the CATCH process was used to assess feasibility. RESULTS: Our overall experience and data revealed a strong preference for the CATCH model, high levels of engagement and satisfaction with CATCH sessions, and positive presenter as well as physicians-involved and mentor experiences. Participants reported that the CATCH model is feasible, engages physicians, promotes a safe learning environment, facilitates awareness of tools for case analysis, and provides opportunities to create "CATCH of the Day" recommendations to support translation of learning to clinical practice. CONCLUSIONS: The CATCH model has significant potential to strengthen clinical case rounds in pediatric hospital medicine. Future research is needed to assess the effectiveness of the model at additional sites and across medical specialities.

Resumo Objetivou-se analisar fatores associados ao near miss neonatal em Cuiabá, Mato Grosso. Estudo caso-controle de nascidos vivos em capital do Centro-Oeste brasileiro, de janeiro de 2015 a dezembro de 2018, com 931 casos e 1.862 controles. Os dados foram coletados no Sistema de Informações sobre Nascidos Vivos e no Sistema de Informações sobre Mortalidade. As variáveis foram organizadas seguindo o modelo hierárquico. A associação foi analisada por meio de regressão logística, com nível de significância de 5%. Os dados foram expressos em odds ratio (OR) bruta e ajustada e respectivos intervalos de confiança (IC95%). Mantiveram-se associados ao near miss neonatal: mães com duas (OR = 1,63; IC95%: 1,01-2,63) ou três ou mais gestações anteriores (OR = 1,87; IC95%: 1,09-3,21), sem nenhum filho (OR = 2,57; IC95%: 1,56-4,24) ou com um filho vivo ao nascer (OR = 1,53; IC95%: 1,04-2,26), gravidez múltipla (OR = 4,57; IC95%: 2,95-7,07), menos de seis consultas de pré-natal (OR = 2,20; IC95%: 1,77-2,72), partos realizados em hospitais públicos/universitários (OR = 2,25; IC95%: 1,60-3,15) e filantrópicos (OR = 1,62; IC95%: 1,16-2,26), apresentação não cefálica (OR = 2,71; IC95%: 1,87-3,94) e trabalho de parto não induzido (OR = 1,47 IC95%: 1,18-1,84).

Abstract We aimed to analyze factors associated with neonatal near-miss in Cuiabá, State of Mato Grosso, Brazil by performing a case-control study of live births in a capital city of central-western Brazil from January 2015 to December 2018 that included 931 cases and 1,862 controls. Data were obtained from the Live Births Information System and the Mortality Information System and variables were organized according to the hierarchical model. Association was analyzed by logistic regression with a 5% significance level. Data were expressed as crude and adjusted odds ratio (OR) and respective confidence intervals (95%CI). The following factors were associated with neonatal near miss: mothers with two (OR = 1.63; 95%CI: 1.01-2.63) or three or more previous pregnancies (OR=1.87; 95%CI: 1.09-3.21), without any live children (OR = 2.57; 95%CI: 1.56-4.24 ) or one live child at birth (OR = 1.53; 95%CI: 1.04-2.26), multiple pregnancy (OR = 4.57; 95%CI: 2.95-7.07), fewer than six prenatal consultations (OR = 2.20; 95%CI: 1.77-2.72), whose deliveries took place in public/university hospitals (OR = 2.25; 95%CI: 1.60-3.15) or philanthropic hospitals (OR = 1.62; 95%CI: 1.16-2.26), with non-cephalic presentation (OR = 2.71 95%CI: 1.87-3.94) and uninduced labor (OR = 1.47; 95%CI: 1.18-1.84).

Association between near miss maternal with sociodemographic factors and health assistants / Associação entre o near miss materno com fatores sociodemográficos e assistenciais de saúde

Abstract Objectives: evaluate the association between the maternal near miss rate (TNMM) and sociodemographic and health care factors. Methods: this is an aggregated, cross- sectional epidemiological survey, with regression analysis and spatial analysis, with the units of analysis being the 399 municipalities that make up the four health macro- regions in the state of Paraná, Brazil. Data from the years 2018 to 2021 were obtained through the state maternal near miss report and monitoring system. Results: the state's total TNMM was 6.4 per 1,000 live births, with an increasing trend during the studied period (p<0.001). Sociodemographic and healthcare factors were not associated with TNMM, except for municipalities with a higher degree of urbanization (β adjusted=0.022; CI95%=0.002-0.041) and located in the northern health macro-region (β adjusted=12.352; CI95%= 10.779-15.099), demonstrated by clusters with high and positive associations (high-high). Conclusion: the lack of association with sociodemographic and care factors may be due to their low effect on near miss, or the underreporting of near miss cases in the state. The differences found can be justified by the organization of health services and the intense regionalization of municipalities belonging to the macronorth, which have a better near miss report culture.

Resumo Objetivos: avaliar a associação existente entre a taxa de near miss materno (TNMM) com fatores sociodemográficos e assistenciais de saúde. Métodos: trata-se de uma pesquisa epidemiológica agregada, transversal, com análises de regressão e análise espacial, sendo as unidades de análise os 399 municípios que compõem as quatro macrorregiões de saúde do estado do Paraná, Brasil. Os dados provenientes dos anos de 2018 a 2021 foram obtidos por meio do sistema estadual de notificação e monitoramento do near miss materno. Resultados: a TNMM total do estado foi de 6,4 por 1.000 nascidos-vivos, com tendência de aumento no período estudado (p<0,001). Fatores sociodemográficos e assistenciais não se associaram com a TNMM, exceto municípios com maior grau de urbanização (β ajustado=0,022; IC95%= 0,002-0,041) e localizados na macrorregião norte de saúde (β ajustado=12,352; IC95%= 10,779; 15,099), demonstrado por clusters com associações altas e positivas (high- high). Conclusão: a ausência de associação com os fatores sociodemográficos e assistenciais podem decorrer do baixo efeito dos mesmos sobre o near miss, ou à subnotificação de casos de near miss materno no estado. As diferenças encontradas podem ser justificadas pela organização dos serviços de saúde e intensa regionalização dos municípios pertencentes à macronorte, os quais apresentam melhor cultura de notificação de near miss.

Factors associated with exclusive breastfeeding in "Near Miss" neonates in Brazil

Abstract Objective To assess the association between sociodemographic and perinatal factors and hospital practices to encourage exclusive breastfeeding in near miss neonates in maternity hospitals. Methods This is a prospective cohort of live births from the survey "To be born in Brazil" conducted between 2011 and 2012. The weighted number of newborns who met the neonatal near miss criteria was 832. Exclusive breastfeeding at hospital discharge and 45 days after delivery were dependent variables of the study. The sociodemographic and perinatal factors of the puerperal women and hospital practices to encourage breastfeeding were independent variables. The data were analyzed with Poisson regression and set with p value<0.05. Is exclusive breastfeeding in neonatal near misses associated with factors related to sociodemographic conditions, maternal characteristics and the organization of health services? Results Data from 498 women and their children were analyzed. Mothers with incomplete primary education were more likely (36%) to have exclusive breastfeeding (RR: 1.36; 95% CI: 1.06-1.74) at discharge. Women who did not offer the breast to the newborn in the joint accommodation (65%) were less likely to be breastfeeding exclusively (RR: 0.65; 95% CI: 0.56-0.75) at discharge. Variables that increased the probability of exclusive breastfeeding after 45 days of delivery were primiparity (RR: 1.36; 95% CI: 1.08-1.69) and having the newborn in the delivery room (RR: 1.90; 95% CI: 1.12-3.24). Conclusion Exclusive breastfeeding in neonatal near misses was associated with maternal characteristics and important hospital practices, such as being breastfed in the joint accommodation and the newborn being in the mother's lap in the delivery room.

Entre a busca por assistência e sua efetivação: peregrinação de gestantes e puérperas com quadro de Near Miss Materno / Between the search for assistance and its realization: the peregrination of pregnant and postpartum women with Maternal Near Miss

Resumo Este estudo, de caráter misto e sequencial exploratório, objetivou identificar padrões relacionados a trajetória de mulheres gestantes e puérperas que evoluíram para situações de risco, desde sua chegada em um primeiro serviço de assistência até sua admissão em uma maternidade terciária. A fase quantitativa analisou 1.703 prontuários e registros de internação de mulheres assistidas em três maternidades terciárias da Região Metropolitana de Fortaleza, no Ceará, entre 2010 e 2019. Na fase qualitativa, realizada entre janeiro e setembro de 2020, participaram 14 mulheres sobreviventes ao Near Miss Materno (NMM), por meio da Entrevista Narrativa Autobiográfica de Schütze. Os achados desvelam como atrasos relacionados aos profissionais e ao sistema de saúde contribuíram para a peregrinação de gestantes e puérperas e, consequentemente, para os quadros de NMM. A peregrinação destas mulheres associa-se a problemas nas estruturas da rede de atenção e dos serviços de saúde. Assim, fazem-se necessários o uso de ferramentas de acompanhamento da qualidade do serviço prestado pelos profissionais de saúde, os processos assistenciais bem estabelecidos, as estruturas físicas e as Redes de Atenção à Saúde (RAS), que suportem o seguimento desses processos.

Abstract This mixed-method and sequential exploratory study aims to identify patterns related to the trajectory of pregnant and puerperal women who evolved to risk situations, from arrival in a first care service to admission to a tertiary maternity hospital. The quantitative phase analyzed 1,703 medical records and hospitalization records of women assisted in three tertiary maternity hospitals in the Metropolitan Region of Fortaleza, Ceará, from 2010 to 2019. The qualitative phase was conducted from January to September 2020 with 14 women survivors of Maternal Near Miss (MNM), using Schütze's Autobiographical Narrative Interview. The findings reveal how delays related to professionals and the health system contributed to the pilgrimage of pregnant and postpartum women and, consequently, to the MNM cases. The peregrination of these women is associated with problems in the structures of the Care Network and the services. Thus, it becomes necessary to use tools to monitor the quality of the service provided by health professionals and to provide well-established care processes, physical structures, and the healthcare networks that support the follow-up of these processes.

Prevalência e desfechos materno-fetais de pacientes internadas por amniorrexe prematura no pré-termo no Hospital Universitário da Faculdade de Medicina de Jundiaí nos anos de 2020 e 2021 / Prevalence and maternal-fetal outcomes in patients hospitalized with preterm premature rupture of membranes at the University Hospital of Jundiaí's Medical School in the years 2020 and 2021

Objetivo: Atualizar a estatística do serviço, reconhecendo a prevalência de amnior- rexe prematura no pré-termo e seus principais desfechos materno-fetais. Méto- dos: Estudo transversal realizado pela análise de prontuários médicos de pacien- tes internadas devido a amniorrexe prematura no pré-termo e de seus respectivos conceptos no Hospital Universitário da Faculdade de Medicina de Jundiaí durante o período de janeiro de 2020 a dezembro de 2021. Resultados: Participaram da pesquisa 161 pacientes e 166 conceptos, resultando em uma prevalência de 2,12% no período estudado, com intervalo de confiança de 95% (1,80-2,47). Entre os des- fechos maternos, 2,5% das gestantes compunham critérios para near miss mater- no; enquanto entre os desfechos fetais, o resultado foi de 54,8% dos conceptos apresentando complicações, sendo as mais prevalentes a síndrome do desconfor- to respiratório (36,3%), icterícia (39,5%), baixo peso (27,5%) e hipoglicemia (24,2%). Além disso, 40,4% necessitaram de internação na unidade de terapia intensiva, 22,9% foram classificados como near miss neonatal e 4,4% foram a óbito. Conclu- são: Os resultados seguiram os padrões nacionais e internacionais esperados para prevalência de amniorrexe prematura no pré-termo e seus desfechos materno-fe- tais, com alta porcentagem de internações e complicações neonatais e baixa taxa de complicações maternas.

Objective: To update service statistics, recognizing the preva- lence of the pathology and its main outcomes. Methods: Cros- s-sectional study carried out through the analysis of medical records of patients hospitalized due to preterm premature rup- ture of membranes and their respective fetuses at the Univer- sity Hospital of Jundiaí's Medical School during the period from January 2020 to December 2021. Results: A total of 161 patients and 166 fetuses participated in the research, resulting in a pre- valence of 2.12% in the period studied with 95% confidence in- terval (1.80-2.47). About the outcomes, 2.5% of the pregnant wo- men composed the criteria for maternal near miss; as for the fetus, complications evolved in 54.8% of the fetuses, the most prevalent being respiratory distress syndrome (36.3%), jaundice (39.5%), low birth weight (27.5%) and hypoglycemia (24.2%). In addition, 40.4% required admission to the intensive care unit, 22.9% were neonatal near miss and 4.4% died. Conclusion: The results followed the expected national and international standards for the prevalence of preterm premature rupture of membranes and its maternal and fetal outcomes, with a high percentage of hospitalizations and neonatal complications, and a low rate of maternal complications.

Neonatal outcomes according to different degrees of maternal morbidity: cross-sectional evidence from the Perinatal Information System (SIP) of the CLAP network.

BACKGROUND: The burden of maternal morbidity in neonatal outcomes can vary with the adequacy of healthcare provision and tool implementation to improve monitoring. Such information is lacking in Latin American countries, where the decrease in severe maternal morbidity and maternal death remains challenging. OBJECTIVES: To determine neonatal outcomes according to maternal characteristics, including different degrees of maternal morbidity in Latin American health facilities. METHODS: This is a secondary cross-sectional analysis of the Perinatal Information System (SIP) database from eight health facilities in five Latin American and Caribbean countries. Participants were all women delivering from August 2018 to June 2021, excluding cases of abortion, multiple pregnancies and missing information on perinatal outcomes. As primary and secondary outcome measures, neonatal near miss and neonatal death were measured according to maternal/pregnancy characteristics and degrees of maternal morbidity. Estimated adjusted prevalence ratios (PRadj) with their respective 95% CIs were reported. RESULTS: In total 85,863 live births were included, with 1,250 neonatal near miss (NNM) cases and 695 identified neonatal deaths. NNM and neonatal mortality ratios were 14.6 and 8.1 per 1,000 live births, respectively. Conditions independently associated with a NNM or neonatal death were the need for neonatal resuscitation (PRadj 16.73, 95% CI [13.29-21.05]), being single (PRadj 1.45, 95% CI [1.32-1.59]), maternal near miss or death (PRadj 1.64, 95% CI [1.14-2.37]), preeclampsia (PRadj 3.02, 95% CI [1.70-5.35]), eclampsia/HELPP (PRadj 1.50, 95% CI [1.16-1.94]), maternal age (years) (PRadj 1.01, 95% CI [<1.01-1.02]), major congenital anomalies (PRadj 3.21, 95% CI [1.43-7.23]), diabetes (PRadj 1.49, 95% CI [1.11-1.98]) and cardiac disease (PRadj 1.65, 95% CI [1.14-2.37]). CONCLUSION: Maternal morbidity leads to worse neonatal outcomes, especially in women suffering maternal near miss or death. Based on SIP/PAHO database all these indicators may be helpful for routine situation monitoring in Latin America with the purpose of policy changes and improvement of maternal and neonatal health.

Clinical, epidemiological and laboratory characteristics of cases of Covid-19-related maternal near miss and death at referral units in northeastern Brazil: a cohort study.

Objective: Covid-19 poses a major risk during pregnancy and postpartum, resulting in an increase in maternal mortality worldwide, including in Brazil; however, little research has been conducted into cases of a near miss. This study aimed to describe the frequency of COVID-19-related near miss and deaths during pregnancy or in the postpartum in referral centers in northeastern Brazil, as well as the clinical, epidemiological, and laboratory characteristics of the women who experienced a severe maternal outcome.Methods: A retrospective and prospective cohort study was performed between April 2020 and June 2021 with hospitalized pregnant and postpartum women with a diagnosis of COVID-19 confirmed by real-time polymerase chain reaction (RT-PCR). Data from five tertiary hospitals in northeastern Brazil were evaluated. Descriptive statistical analysis was performed using Epi Info, version 7.2.5.0.Results: A total of 463 patients were included. Of these, 64 (14% of the sample) had a severe maternal outcome, with 42 cases of near miss (9%) and 22 maternal deaths (5%). Patients who had a severe maternal outcome were predominantly young (median age 30 years) and 65.6% were black or brown-skinned. The women had between 6 and 16 years of schooling; 45.3% had a stable partner; 81.3% were pregnant at the time of admission to the study; and 76.6% required a Cesarean section. The great majority (82.8%) had severe acute respiratory syndrome (SARS). Other complications included hypertensive syndromes (40.6%), pneumonia (37.5%), urinary tract infections (29.7%), acute renal failure (25.0%) and postpartum hemorrhage (21.9%). Sepsis developed in 18.8% of cases, neurological dysfunction in 15.6%, and hepatic dysfunction and septic shock in 14.1% of cases each. The relative frequency of admission to an intensive care unit was 87.5%, while 67.2% of the patients required assisted mechanical ventilation, and 54.7% required noninvasive ventilation. Antibiotics were prescribed in 93.8% of cases and corticosteroids in 71.9%, while blood transfusion was required in 25.0% of cases and renal replacement therapy in 15.6%. Therapeutic anticoagulants were administered to 12.5% of the patients. Of the patients who had a severe maternal outcome, the frequency of respiratory dysfunction was 93.8%, with 50.0% developing neurological dysfunction and 37.5% cardiovascular dysfunction. Hematological dysfunction was found in 29.7%, renal dysfunction in 18.8%, and uterine dysfunction in 14.1%. Hepatic dysfunction occurred in 7.8% of the sample. The near-miss ratio for Covid-19 was 1.6/1000 live births and the maternal mortality ratio for Covid-19 was 84.8/100,000 live births, with a mortality index of 34.4% in the sample.Conclusion: This study revealed a low Covid-19-related maternal near miss (MNM) ratio of 1.6/1000 live births and a high Covid-19-related maternal mortality ratio (MMR) of 84.81/100,000 live births. The mortality index was also high. Most of the patients were admitted while pregnant, were young, married and black or brown-skinned, and none had completed university education. The majority had SARS and required admission to an intensive care unit and mechanical ventilation. Most were submitted to a Cesarean section.

Surveillance of severe maternal morbidity and maternal mortality in maternity hospitals of the Latin American and Caribbean network - Red CLAP: study protocol.

The sustained reduction in maternal mortality in America underlines the need to analyse women who survived a complication that could have been fatal if appropriate and timely care had not been taken. Analysis of maternal near-miss (MNM) cases, as well as potentially life-threatening conditions (PLTC), are considered indicators for monitoring the quality of maternal care. The specific objective of this study protocol is to develop a surveillance system for PLTC, MNM and maternal mortality, as primary outcomes, in Latin American and Caribbean maternal healthcare institutions. Secondarily, the study was designed to identify factors associated with these conditions and estimate how often key evidence-based interventions were used for managing severe maternal morbidity. This is a multicenter cross-sectional study with prospective data collection. The target population consists of all women admitted to health centres participating in the network during pregnancy, childbirth, or the postpartum period. Variables describing the sequence of events that may result in a PLTC, MNM or maternal death are recorded. Relevant quality control is carried out to ensure the quality of the database and confidentiality. Centres with approximately 2,500 annual deliveries will be included to achieve a sufficient number of cases for calculation of indicators. The frequency of outcome measures for PLTC, MNM and maternal mortality and their confidence intervals and differences between groups will be calculated using the most appropriate statistical tests. Similar procedures will be performed with variables describing the use of evidence-based practices. Networking creates additional possibilities for global information management and interaction between different research groups. Lessons can be learned and shared, generating scientific knowledge to address relevant health problems throughout the region with provision of efficient data management.

Association between neonatal near miss and infant development: the Ribeirão Preto and São Luís birth cohorts (BRISA).

AIM: To analyze the association between neonatal near miss and infant development at two years. METHODS: Data from two birth cohorts, one conducted in Ribeirão Preto (RP)/São Paulo and the other in São Luís (SL)/Maranhão, were used. The cognitive, motor and communication development of children was evaluated using the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III). The following criteria were used for the definition of NNM: birth weight < 1,500 g, 5-min Apgar score < 7, gestational age < 32 weeks, and report of congenital malformations. The relationship between neonatal near miss and development was assessed using the weighted propensity score from the Inverse Probability of Treatment Weighting (IPTW). A directed acyclic graph was built to select the adjustment variables. RESULTS: A total of 1,050 mother-newborn dyads were evaluated in SL and 1,840 in RP. Regarding outcomes in SL and RP, respectively, 2.4% and 17.3% of the children were not competent in the cognitive domain, 12.1% and 13.3% in the receptive communication domain, 39.2% and 47.1% in the expressive communication domain, 20.7% and 12.6% in the fine motor domain, and 14.3% and 13.8% in the gross motor domain. The prevalence of neonatal near miss was 5.4% in SL and 4.3% in RP. Unadjusted analysis showed an association of neonatal near miss with fine motor development in SL and RP and with the cognitive, receptive communication, expressive communication, and gross motor domains only in RP. These associations remained after adjusted analysis. CONCLUSION: Neonatal near miss is a risk factor for developmental delays.

Uterine tamponade in postpartum hemorrhage with handmade balloons: Comparison of manufacturing, infusion, and total times.

OBJECTIVE: To compare the manufacturing, infusion, and total times of handmade balloons for uterine tamponade using the El Hennawy and Alves techniques, given the failure of initial measures and uterotonic therapy to control postpartum hemorrhage. METHODS: An open clinical trial (clinical article) was conducted among 30 physicians, residents, and assistants in an Obstetrics Department. Each participant manufactured and infused one of two different balloons compared in the study, in a randomly predefined sequence. The manufacturing and infusion times were timed by the researchers and their medians were compared using the t test or Mann-Whitney U test. RESULTS: The manufacturing time of the El Hennawy balloon was 72 s lower in relation to the Alves balloon (P < 0.010). Regarding the infusion time, the Alves balloon was filled faster than the El Hennawy balloon (P < 0.010). The total time (manufacturing and infusion) of Alves balloon was also lower than the El Hennawy device (P < 0.010). CONCLUSIONS: Although the El Hennawy balloon was manufactured more quickly, the total time of manufacturing and infusing the Alves balloon was much faster, which makes it the most suitable device to be used in critical situations of postpartum hemorrhage.

Predicting severe maternal outcomes in a network of sentinel sites in Latin-American countries.

OBJECTIVE: This study aimed to determine incidences of potentially life-threatening conditions (PLTC), maternal near misses (MNM), and maternal deaths (MD) in women who gave birth in participating facilities, and to determine the probability that a pregnancy involving a PLTC would evolve into an MNM and/or an MD. METHODS: This was a multicentric observational study implemented on a maternal network from August 2018 to May 2019 in five Latin-American countries. We summarized categorical variables as frequencies and continuous variables with median, interquartile range, and standard deviations. Positive and negative likelihood ratios were calculated and multivariate predictive models were built. RESULTS: There were 33 901 deliveries and miscarriages, of which 8.0% had at least one PLTC and 0.6% had an MNM. Hypertensive disorder was the most frequent condition to evolve into a severe maternal outcome. CONCLUSION: Identifying PLTC can help to prevent MNM and MD. The inclusion of these predictors in a real-time data registration system like the Perinatal Informatic System could work as a surveillance tool for early detection, leading to a reduction in the rate of worsening conditions.

Neonatal near miss and mortality and associated factors: cohort study of births in the city of Rio de Janeiro, RJ, Brazil / Near miss e mortalidade neonatal e fatores associados: estudo de coorte de nascimentos do município do Rio de Janeiro, RJ

Abstract Objective: The aim of this study was to investigate factors associated with neonatal near miss and mortality of the live birth cohort in the city of Rio de Janeiro, Brazil, in 2015. Methods: Population-based retrospective cohort of live births (LB) of single pregnancy with 0-27 days of follow-up. Data were obtained from the Brazilian Live Birth and Mortality Information Systems. Logistic regressions with the analytical strategy of hierarchical determination were used for cases of near miss and deaths separately. Results: The cohort was composed of 85,850 LB. For every one thousand LB, about 16 were cases of near miss and six died. Maternal level of education, skin color, and age and adequacy of prenatal care were associated with neonatal near miss; for deaths, presentation of LB at delivery, birth weight, gestational age, and five-minute Apgar score are added. Conclusions: Besides confirming the effect of low birth weight, prematurity, and asphyxia on neonatal death, socioeconomic vulnerability markers - low education level and brown or black skin colors - were associated with neonatal death and near miss. Absent or inadequate prenatal care showed a strong association with both outcomes, being stronger for neonatal death. Investments in the quality of prenatal care and reduction of disparities in health care are necessary in Rio de Janeiro.

Resumo Objetivo: Investigar fatores associados aos near miss e óbito neonatais na coorte de nascidos vivos do município do Rio de Janeiro (RJ), 2015. Métodos: Coorte retrospectiva de base populacional de nascidos vivos de gravidez única com seguimento de até 27 dias. Dados obtidos dos Sistemas de Informações sobre Nascidos Vivos e sobre Mortalidade. Foram usadas regressão logística e estratégia analítica de determinação hierárquica separadamente para casos de near miss e óbitos. Resultados: Coorte composta de 85.850 nascidos vivos. Para cada mil nascidos vivos, 16 foram casos de near miss e seis evoluíram para óbito. Escolaridade, cor da pele e idade maternas e adequação do pré-natal estiveram associadas ao near miss neonatal; para óbitos, acrescenta-se apresentação do NV no parto, peso, idade gestacional e Apgar no 5º minuto. Conclusões: Além de confirmar o efeito do baixo peso, da prematuridade e da asfixia no óbito neonatal, variáveis marcadoras de vulnerabilidade socioeconômica — baixa escolaridade e cor da pele parda ou preta — mostraram-se associadas ao óbito e ao near miss neonatal. Pré-natal ausente ou inadequado mostrou forte associação com ambos os desfechos, mais intensa para o óbito. Investimentos na qualificação do pré-natal e na redução das desigualdades na saúde são necessários no Rio de Janeiro.

Factors associated with neonatal near miss in a Midwest capital in Brazil / Fatores associados ao near miss neonatal em uma capital do Centro-Oeste do Brasil

Abstract Objectives: to estimate neonatal near miss rates and investigate sociodemographic, obstetric, childbirth, and neonate factors residing in a Midwest capital city. Methods: observational cohort study of live births from Cuiabá in the period of 2015 to 2018, with data from the Sistemas de Informações sobre Mortalidade e sobre Nascidos Vivos (Mortality and Live Birth Information Systems). The neonatal near miss rate was calculated according to sociodemographic, obstetric, childbirth, and neonate variables. Logistic regression model was adjusted to analyze the factors associated with neonatal near miss. Results: the neonatal near miss rate was 22.8 per thousand live births and the variables showed an association with the outcome were: maternal age 35 years or older (OR=1.53; CI95%=1.17-2.00), having fewer than six prenatal consultations (OR=2.43; CI95%=2.08-2.86), non-cephalic fetal presentation (OR=3.09; CI95%=2.44-3.92), multiple pregnancy (OR=3.30; CI95%=2.57- 4.23), no live birth (OR=1.62; CI95%=1.34-1.96) or one live birth (OR=1.22; CI95%=1.00-1.48), delivery in public/university hospital (OR=2.16; CI95%=1.73-2.71) and philanthropic hospital (OR=1.51; CI95%=1.19-1.91) and non-induced labor (OR=1.50; CI95%=1.25-1.80). Conclusion: the neonatal near miss rate was 3.04 cases for each death, and neonatal near miss was influenced by maternal characteristics, obstetric history, type of birth hospital, and delivery care organization.

Resumo Objetivos: estimar as taxas de near miss neonatal e investigar os fatores sociodemográficos, obstétricos, do parto e dos neonatos residentes em uma capital do Centro-Oeste. Métodos: estudo observacional de coorte de nascidos vivos de Cuiabá no período de 2015 a 2018, com dados dos Sistemas de Informações sobre Mortalidade e sobre Nascidos Vivos. Foi calculada a taxa de near miss neonatal conforme as variáveis sociodemográficas, obstétricas, do parto e dos neonatos. Modelo de regressão logística foi ajustado para analisar os fatores associados ao near miss neonatal. Resultados: a taxa de near miss neonatal foi 22,8 por mil nascidos vivos e as variáveis que apresentaram associação com o desfecho foram: idade materna de 35 anos ou mais (OR=1,53; IC95%=1,17-2,00), realizar menos de seis consultas de pré-natal (OR=2,43; IC95%=2,08-2,86), apresentação fetal não cefálica (OR=3,09; IC95%=2,44-3,92), gravidez múltipla (OR=3,30; IC95%=2,57-4,23), nenhum filho nascido vivo (OR=1,62; IC=1,34-1,96) ouum filho nascido vivo (OR=1,22; IC95%=1,00-1,48), parto em hospital público/universitário (OR=2,16; IC95%=1,73-2,71) e filantrópico (OR=1,51; IC95%=1,19-1,91)e trabalho de parto não induzido (OR=1,50; IC95%=1,25-1,80). Conclusão: a taxa de near miss neonatal foi de 3,04 casos para cada óbito, sendo que o near miss neonatal foi influenciado pelas características maternas, histórico obstétrico, tipo do hospital do nascimento e organização da assistência ao parto.

Morbimortalidade materna no Brasil e a urgência de um sistema nacional de vigilância do near miss materno / Maternal morbidity and mortality in Brazil and the urgency of a national surveillance system for maternal near miss / La morbimortalidad materna en Brasil y la urgencia de un sistema nacional de vigilancia del near miss materno

A Organização Mundial da Saúde (OMS) recomenda a análise dos casos de morbidade materna severa/near miss materno como complemento às análises das mortes de mães, dado que a incidência é mais elevada e os fatores preditivos dos dois desfechos são semelhantes. Tendo em vista que as razões de mortalidade materna, no Brasil, têm se mantido constantes apesar do compromisso firmado durante a Assembleia Geral da Organização das Nações Unidas (ONU), em 2015, o objetivo deste artigo é propor um sistema nacional de vigilância de near miss materno. Propõe-se a inclusão dos eventos near miss materno na Lista Nacional de Notificação Compulsória de Doenças, Agravos e Eventos de Saúde Pública, por meio da compatibilização dos critérios diagnósticos de near miss materno, informados pela OMS, com os códigos da Classificação Internacional de Doenças (CID) para identificação dos casos. Tendo em vista que a vigilância em saúde se faz baseada em diversas fontes de informações, a notificação poderia ser feita pelos profissionais dos serviços de saúde tão logo fosse identificado um caso confirmado ou suspeito. A partir do estudo dos fatores associados aos desfechos, espera-se a avaliação mais qualificada dos serviços voltados à assistência obstétrica e consequente implementação de políticas mais eficientes de prevenção não apenas do óbito materno, mas de eventos que podem tanto causar sequelas irreversíveis à saúde da mulher quanto aumento do risco de óbito fetal e neonatal.

The World Health Organization (WHO) recommends the analysis of severe maternal morbidity/maternal near miss cases as complementary to the analysis of maternal deaths since the incidence is higher and the predictive factors of the two outcomes are similar. Considering that the reasons for maternal mortality in Brazil have remained constant despite the commitment made during the General Assembly of the United Nations in 2015, this article aims to propose a nationwide maternal near miss surveillance system. We propose the inclusion of maternal near miss events in the National List of Compulsory Notification of Diseases, Injuries, and Public Health Events, via the compatibility of the diagnostic criteria of maternal near miss, informed by the WHO, with the codes of the International Classification of Diseases for the identification of cases. Considering that health surveillance is based on several sources of information, notification could be made by health service professionals as soon as a confirmed or suspected case is identified. With the study of the factors associated with the outcomes, we expect a qualified evaluation of the services focused on obstetric care and consequent implementation of more efficient policies to prevent not only maternal death but also events that can both cause irreversible sequelae to women's health and increase the risk of fetal and neonatal death.

Teniendo en vista que la vigilancia en salud se basa en diversas fuentes de Informaciones, la notificación podría ser hecha por los profesionales de los servicios de salud, tan pronto fuese identificado un caso confirmado o sospechoso. Se espera que el estudio de los factores asociados a los resultados conduzca a una evaluación más calificada de los servicios de atención obstétrica y a la consecuente implementación de políticas más eficientes de prevención no solo de la muerte materna; sino de eventos que pueden tanto causar secuelas irreversibles a la salud de la mujer como aumento del riesgo de muerte fetal y neonatal.

Realizou-se também busca de dados nas seguintes bases secundárias: Notify - World Health Organization (WHO), Organização Pan-Americana de Saúde (OPAS) e Google Scholar. Para a avaliação da qualidade dos estudos foi utilizada a ferramenta MINORS. Resultados Foram identificados 551 estudos, após as etapas de avaliação, foram incluídos oito deles para a revisão sistemática. Estes foram divididos entre resultados, processos e estratégias de prevenção de eventos adversos. Quanto a classificação da qualidade dos estudos, dois obtiveram classificação boa. Conclusão Os resultados apontam a ocorrência de eventos adversos ocorridos em alguma etapa do processo de doação e transplante de órgãos e tecidos, como: reações adversas relacionadas a medicamentos; neurotoxicidade; aumento do tempo de hospitalização; reintervenções cirúrgicas; queda; coma; óbito; falha ou perda do enxerto. Destaca-se que os eventos adversos possivelmente ainda são subnotificados.

Abstract Objective To synthesize and critically evaluate the scientific evidence from observational studies on biosurveillance systems and adverse event reporting in organ donation and transplantation. Methods Systematic review of observational studies following the recommendations of the Methodological Guidelines (REBRATS) and Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA). Primary studies and case reports on biosurveillance and/or adverse events in organ donation and/or transplantation, without restriction of publication date or language were included. Six electronic databases were used in the scientific literature search: Medical Literature Analysis and Retrieval System Online (MEDLINE) (via PubMed), Excerpta Medica Database (Embase), Web of Science, LILACS, Scopus and the electronic library Scielo. A data search was also performed in the following secondary databases: Notify - World Health Organization (WHO), Pan American Health Organization (PAHO) and Google Scholar. The MINORS tool was used to assess the quality of studies. Results 551 studies were identified, and after the evaluation steps, eight of them were included in the systematic review. These were divided into results, processes and strategies for preventing adverse events. Regarding the classification of the quality of studies, two obtained a good classification. Conclusion The results indicate the occurrence of adverse events at some stage of the organ and tissue donation and transplantation process, such as: adverse drug-related reactions; neurotoxicity; longer length of hospital stay; surgical reinterventions; falls; coma; death; graft failure or loss. The fact that adverse events are possibly still underreported is noteworthy.

Factors associated with severe maternal, fetuses and neonates' outcomes in a university hospital in Rio de Janeiro State / Fatores associados a desfechos graves maternos, fetais e neonatais em um hospital universitário do estado do Rio de Janeiro

Abstract Objectives: to estimate the burden of parturients, fetuses and neonate's severe morbidity and mortality and investigate the association between maternal and their conceptus outcomes. Methods: retrospective cohort of 546 parturients and their conceptus in a university hospital, reference for high-risk pregnancy, in the metropolitan region II of Rio de Janeiro State from 2015 to 2017. We classified parturients according to obstetric morbidity (OM) in direct, indirect, or mixed, and their outcomes as: 1) no severity, 2) severe complication (SC), 3) critical intervention/Intensive Care Unit, and 4) greater severity -maternal near-miss (MNM) or death. We evaluated the conceptus as neonatal near-miss (NNM) and fetal and neonatal deaths. We estimated morbimortality indicators and associated factors (multinomial logistic regression). Results: OM was frequent: 29.3% indirect, 22.3% direct, and 15.8% mixed. There were eight cases of NMM, seven with direct MO. Among the conceptus: 7.5% were NNM cases and 4.4%, deaths. The risk of severe maternal outcomes was 16.8 and neonatal, 102.6/1000 live births. Mixed race, inadequate prenatal care, CG and NMM/death, were associated with NNM. Inadequate prenatal care and maternal NM/death were associated with conceptus deaths. Conclusion: even in a reference unit, sociodemographic, and health care inequalities negatively affect mothers and, consequently, their children.

Resumo Objetivos: estimar a carga de morbidade grave e mortalidade em parturientes, fetos e neonatos e investigar a associação entre os desfechos maternos e de seus conceptos. Métodos: coorte retrospectiva de 546 parturientes e seus conceptos no hospital universitário referência para gravidez de alto risco da região metropolitana II do estado do Rio de Janeiro (ERJ), de 2015 a 2017. Classificamos as parturientes segundo morbidade obstétrica (MO) em direta, indireta e mista, e seus desfechos como: 1) sem gravidade, 2) complicação grave (CG), 3) intervenção crítica/ Unidade Terapia Intensiva e 4) maior gravidade-near miss materno (NMM) ou óbito. Avaliamos os conceptos quanto a near miss neonatal (NMN), óbitos fetais e neonatais. Estimamos indicadores de morbimortalidade, e fatores de associação (regressão logística multinomial). Resultados: MO foi frequente: 29,3% indiretas, 22,3% diretas e 15,8% mista. Ocorreram oito casos de NMM, sete com MO direta. Entre os conceptos,7,5% foram casos de NMN e 4,4%, óbitos. O risco de desfecho grave materno foi 16,8 e neonatal, 102,6 p/1000 nascidos vivos. Estiveram associados ao NMN: cor parda, pré-natal inadequado, CG e NMM/óbito; e ao óbito do concepto: pré-natal inadequado e NMM/óbito. Conclusão: mesmo em situação de referência, desigualdades sociodemográficas e assistenciais afetam negativamente mães e, consequentemente, seus conceptos.

Maternal near miss: before and during the coronavirus disease 2019 pandemic

SUMMARY OBJECTIVE: The aim of this study was to evaluate and compare Maternal Near Miss prevalence and outcomes before and during the coronavirus disease 2019 pandemic. METHODS: This retrospective study was carried out in a university maternity hospital of high complexity. The population was divided into two groups: G1, 1 year before the coronavirus disease 2019 pandemic period (August 2018-July 2019) and G2, 1 year during the pandemic period (August 2020-July 2021). All pregnant/postpartum women hospitalized up to 42 days after the end of pregnancy/childbirth were included, and pregnant women who were admitted with coronavirus disease 2019/flu symptoms were excluded. The association of variables with "Maternal Near Miss" was estimated using logistic regression. RESULTS: A total of 568 women from G1 and 349 women from G2 fulfilled the Maternal Near Miss criteria. The prevalence of Maternal Near Miss in pre-pandemic was 144.1/1,000 live births and during the pandemic was 78.5/1,000 live births. In the analysis adjusted for G1, the factors of days of hospitalization (PR: 1.02, CI: 1.0-1.0, p<0.05), pre-eclampsia (PR: 0.41, CI: 1.4-2.2, p<0.05), and sepsis/severe systemic infection (PR: 1.79, CI: 0.3-0.4, p<0.05) were crucial for women with the Maternal Near Miss condition to have a greater chance of being admitted to the intensive care unit. In G2, low education (PR: 0.45, CI: 0.2-0.9, p<0.05), eclampsia (PR: 5.28, CI: 3.6-7.6, p<0.05), and use of blood products (PR: 6.48, CI: 4.7-8.8, p<0.05) increased the risk of admission to the intensive care unit. CONCLUSION: During the pandemic, there was a lower prevalence of Maternal Near Miss in high-risk pregnancies, fewer hospitalizations, and more deaths compared to the non-pandemic period.

Obstetric and neonatal adverse events and association with care models: a cohort study / Eventos adversos obstétricos y neonatales y asociación con modelos de atención: un estudio de cohorte / Eventos adversos obstétricos e neonatais e associação com os modelos de assistência: um estudo coorte

ABSTRACT Objective: to analyze the prevalence of practices in childbirth care, obstetric and neonatal adverse events and their association with care models in three public health services. Method: this is a prospective cohort study carried out with 548 dyads, postpartum women and their newborns, whose pregnancy was of usual risk and vaginal birth, admitted to hospital in three public services, one with an exclusive care model by nurse-midwives (service A), one with a collaborative model involving obstetric doctors and nurses (service B) and one with an exclusive medical care model (service C). Initially, an interview was carried out with participants, and a second contact was carried out 42 days after birth to complement the collection of the adverse event outcome. Results: in service A, no woman underwent the Kristeller maneuver, episiotomy, directed pushing or more than one vaginal examination per hour. Meanwhile, in service C, 19.3%, 39.9%, 77.1% and 26.3% of women underwent these interventions, respectively. Adverse events occurred in 19.2% of the dyads. Occurrence of adverse events was associated with not using partograph (p=0.001; OR: 11.03; CI: 2.64-45.99) and episiotomy (p=0.042; OR: 1.72; CI: 1. 02-2.91). The mean probability of experiencing an adverse event was 5% in service A, 21% in service B and 24% in service C. Conclusion: adverse events had a lower mean probability of occurrence in the service exclusively operated by nurse-midwives, in which greater application of recommendations for labor and birth care was identified.

RESUMEN Objetivo: analizar la prevalencia de prácticas en la atención del childbirth, eventos adversos obstétricos y neonatales y su asociación con los modelos de atención en tres servicios públicos de salud.

Inicialmente se realizó una entrevista a los participantes y se realizó un segundo contacto a los 42 días del nacimiento para complementar la recopilación del resultado del evento adverso. Resultados: en el servicio A ninguna mujer fue sometida a maniobra de Kristeller, episiotomía, pujo dirigido o más de un examen vaginal por hora. Mientras tanto, en el servicio C, el 19,3%, 39,9%, 77,1% y 26,3% de las mujeres se sometieron a estas intervenciones, respectivamente. Los eventos adversos ocurrieron en el 19,2% de los binomios. La aparición de eventos adversos se asoció con la no utilización del partographa (p=0,001; OR: 11,03; IC: 2,64-45,99) y episiotomía (p=0,042; OR: 1,72; IC: 1,02-2,91). La probabilidad promedio de experimentar un evento adverso fue del 5% en el servicio A, del 21% en el servicio B y del 24% en el servicio C. Conclusión: los eventos adversos tuvieron menor probabilidad promedio de ocurrencia en el servicio operado exclusivamente por enfermeras obstétricas, en el que se identificó mayor aplicación de las recomendaciones de asistencia al childbirth y nacimiento.

RESUMO Objetivo: analisar a prevalência de práticas na atenção ao parto, eventos adversos obstétricos e neonatais e sua associação com modelos assistenciais em três serviços de saúde públicos. Método: estudo coorte prospectivo realizado com 548 binômios, puérperas e seus recém-nascidos, cuja gestação foi de risco habitual e o parto vaginal, internados em três serviços públicos, sendo um com modelo de assistência exclusivo por enfermeiras obstetras (serviço A), um com modelo colaborativo com atuação de médicos e enfermeiras obstetras (serviço B) e um com modelo de assistência exclusiva médica (serviço C). Inicialmente, foi realizada uma entrevista com as participantes e um segundo contato foi realizado após 42 dias do parto para complementar a coleta do desfecho evento adverso. Resultados: no serviço A, nenhuma mulher foi submetida à manobra de Kristeller, episiotomia, incentivos a puxos dirigidos ou mais de um toque vaginal por hora. Enquanto, no serviço C, 19,3%, 39,9%, 77,1% e 26,3% das mulheres foram submetidas a essas intervenções, respectivamente. Os eventos adversos ocorreram em 19,2% dos binômios. A ocorrência dos eventos adversos foi associada ao não uso do partograma (p=0,001; OR: 11,03; IC: 2,64-45,99) e episiotomia (p=0,042; OR: 1,72; IC: 1,02-2,91). A probabilidade média de apresentar algum evento adverso foi de 5% no serviço A, 21% no serviço B e 24% no serviço C. Conclusão: os eventos adversos apresentaram menor probabilidade média de ocorrência no serviço com atuação exclusiva de enfermeiras obstetras, no qual se identificou maior aplicação das recomendações para assistência ao parto e nascimento.
