Survival outcomes and resuscitation process measures in maternal in-hospital cardiac arrest

Assessment and Prediction of Cardiovascular Contributions to Severe Maternal Morbidity

Severe maternal morbidity (SMM) refers to any unexpected outcome directly related to pregnancy and childbirth that results in both short-term delivery complications and long-term consequences to a women's health. This affects about 60,000 women annually in the United States. Cardiovascular contributions to SMM including cardiac arrest, arrhythmia, and acute myocardial infarction are on the rise, probably driven by changing demographics of the pregnant population including more women of extreme maternal age and an increased prevalence of cardiometabolic and structural heart disease. The utilization of SMM prediction tools and risk scores specific to cardiovascular disease in pregnancy has helped with risk stratification. Furthermore, health system data monitoring and reporting to identify and assess etiologies of cardiovascular complications has led to improvement in outcomes and greater standardization of care for mothers with cardiovascular disease. Improving cardiovascular disease-related SMM relies on a multipronged approach comprised of patient-level identification of risk factors, individualized review of SMM cases, and validation of risk stratification tools and system-wide improvements in quality of care. In this article, we review the epidemiology and cardiac causes of SMM, we provide a framework of risk prediction clinical tools, and we highlight need for organization of care to improve outcomes.

Parada cardiorrespiratória obstétrica: construção e validação de instrumento para avaliar o conhecimento da enfermagem

RESUMO Objetivo Construir e validar instrumento para avaliar o conhecimento da enfermagem sobre parada cardiorrespiratória obstétrica. Métodos Estudo metodológico composto pela construção do instrumento, validação de conteúdo por 23 especialistas e validação da consistência interna com 74 profissionais da enfermagem e 99 estudantes de enfermagem. Foram considerados válidos os itens com concordância mínima de 90%, verificada a partir do Índice de Validação de Conteúdo, Razão de Validade de Conteúdo e teste binomial. O alpha de Cronbach foi utilizado para verificar a consistência interna e o valor superior a 0,6 classificado como aceitável. Resultados O instrumento foi composto por16 questões de múltipla escolha, dos 16 itens avaliados, oito possuíram concordância de 100% e seis 95%. A menor razão de validade de conteúdo foi de 0,82 e o alpha de Cronbach foi de 0,694. Conclusões O instrumento foi construído e validado, recomendando-se sua utilização para avaliação do conhecimento em parada cardiorrespiratória obstétrica.

Obstetric cardiopulmonary arrest: construction and validation of an instrument to assess nursing knowledge

ABSTRACT Objective To build and validate an instrument to assess nursing knowledge about obstetric cardiopulmonary arrest. Methods A methodological study consisting of the construction of the instrument, content validation by 23 experts and validation of internal consistency with 74 nursing professionals and 99 nursing students. Items with a minimum agreement of 90%, verified from the Content Validation Index, Content Validity Ratio and binomial test were considered valid. Cronbach’s alpha was used to verify internal consistencyand a value greater than 0.6 was classified as acceptable. Results The instrument consisted of 16 multiple-choice questions, from the 16 items evaluated, eight had 100% agreement by the experts and six had 95%. The lowest content validity ratio was 0.82 and Cronbach’s alpha was 0.694. Conclusions The instrument was constructed and validated, and its use is recommended to assess knowledge in obstetric cardiopulmonary arrest.
