Current concepts in the use of cell salvage in obstetrics.

PURPOSE OF REVIEW: The worldwide leading cause of maternal death is severe maternal hemorrhage. Maternal hemorrhage can be profound leading to an entire loss of blood volume. In the past two decades, Patient Blood Management has evolved to improve patient's care and safety. In surgeries with increased blood loss exceeding 500 ml, the use of cell salvage is strongly recommended in order to preserve the patient's own blood volume and to minimize the need for allogeneic red blood cell (RBC) transfusion. In this review, recent evidence and controversies of the use of cell salvage in obstetrics are discussed. RECENT FINDINGS: Numerous medical societies as well as national and international guidelines recommend the use of cell salvage during maternal hemorrhage. SUMMARY: Intraoperative cell salvage is a strategy to maintain the patient's own blood volume and decrease the need for allogeneic RBC transfusion. Historically, cell salvage has been avoided in the obstetric population due to concerns of iatrogenic amniotic fluid embolism (AFE) or induction of maternal alloimmunization. However, no definite case of AFE has been reported so far. Cell salvage is strongly recommended and cost-effective in patients with predictably high rates of blood loss and RBC transfusion, such as women with placenta accreta spectrum disorder. However, in order to ensure sufficient practical experience in a multiprofessional obstetric setting, liberal use of cell salvage appears advisable.

Documento de consenso de la Sociedad Española de Obstetricia y Ginecologia (SEGO) y el Comité Español Interdisciplinario para la Prevención Vascular (CEIPV). Ventana de oportunidad: prevención del riesgo vascular en la mujer. Resultados adversos del embarazo y riesgo de enfermedad vascular / Consensus document of the Spanish Society of Obstetrics and Gynecology (SEGO) and the Spanish Interdisciplinary Committee for Vascular Prevention (CEIPV). Opportunity window: vascular risk prevention in women. Adverse pregnancy outcomes and risk of vascular disease

Este documento resume la evidencia que existe entre los resultados adversos del embarazo (RAE), tales como son los trastornos hipertensivos, el parto pretérmino, la diabetes gestacional, los defectos en el crecimiento fetal (feto pequeño para la edad gestacional y/o restricción del crecimiento), el desprendimiento de placenta y la pérdida fetal, y el riesgo que tiene una persona gestante de desarrollar factores de riesgo vascular (RV) que pueden terminar provocando enfermedad vascular (EV) futura: cardiopatía coronaria, accidente cerebrovascular, enfermedad vascular periférica e insuficiencia cardíaca. Asimismo, este documento destaca la importancia de saber reconocer los RAE cuando se evalúa el RV en mujeres. Un antecedente de RAE es un indicador suficiente para hacer una prevención primaria de EV. De hecho, adoptar una dieta saludable y aumentar la actividad física entre las mujeres con RAE, de inicio en el embarazo y/o postparto y manteniéndolo a lo largo de la vida, son intervenciones importantes que permiten disminuir el RV. Por otro lado, la lactancia materna también puede disminuir el RV posterior de la mujer, incluyendo menos riesgo de mortalidad. Estudios futuros que evalúen el uso del ácido acetilsalicílico, las estatinas y la metformina, entre otros, en las mujeres con antecedentes de RAE podrían reforzar las recomendaciones sobre el uso de la farmacoterapia en la prevención primaria de la EV entre estas pacientes. Existen diferentes opciones dentro de los sistemas de salud para mejorar la transición de la atención de las mujeres con RAE entre los diferentes profesionales e implementar estrategias para reducir su RV a largo plazo. Una posible estrategia podría ser la incorporación del concepto delcuarto trimestre en las recomendaciones clínicas y las políticas de atención de la salud.(AU)

This document summarises the evidence regarding the association between adverse pregnancy outcomes (APOs), such as hypertensive disorders, preterm birth, gestational diabetes, fetal growth defects (small for gestational age and/or fetal growth restriction), placental abruption, fetal loss, and the risk that a pregnant individual in developing vascular risk factors (VR) that may lead to future vascular disease (VD): coronary heart disease, stroke, peripheral vascular disease, and heart failure. Furthermore, this document emphasises the importance of recognising APOs when assessing VR in women. A history of APOs serves as a sufficient indicator for primary prevention of VD. In fact, adopting a healthy diet and increasing physical activity among women with APOs, starting during pregnancy and/or postpartum, and maintaining it throughout life are significant interventions that can reduce VR. On the other hand, breastfeeding can also reduce the future VR of women, including a lower risk of mortality.Future studies evaluating the use of aspirin, statins, and metformin, among others, in women with a history of APOs could strengthen recommendations regarding pharmacotherapy for primary prevention of VD in these patients. Various healthcare system options exist to improve the transition of care for women with APOs between different healthcare professionals and implement longterm VR reduction strategies. One potential process could involve incorporating the fourth-trimester concept into clinical recommendations and healthcare policies.(AU)

The evolution of the diagnostic criteria of preeclampsia-eclampsia.

As the understanding of the pathophysiology of preeclampsia has improved, its diagnostic criteria have evolved. The classical triad of hypertension, edema, and proteinuria has become hypertension and organ dysfunction-renal, hepatic, neurologic, hematological, or uteroplacental. However, the most recent definitions have largely been based off consensus and expert opinion, not primary research. In this review, we explore how the criteria have evolved, particularly through the second half of the 20th and the beginning of the 21st century and offer a critical appraisal of the evidence that has led the criteria to where they stand today. Some key themes are the following: the debate between having a simple and convenient blood pressure cutoff vs a blood pressure cutoff that accounts for influencing factors such as age and weight; whether a uniform blood pressure threshold, a rise in blood pressure, or a combination is most discriminatory; whether existing evidence supports blood pressure and proteinuria thresholds in diagnosing preeclampsia; and whether using flow-charts and decision trees might be more appropriate than a single set of criteria. We also discuss the future of a preeclampsia diagnosis. We challenge the move toward a broad (vs restrictive) diagnosis, arguing instead for criteria that directly relate to the prognosis of preeclampsia and the response to treatments.

Current state and future direction of task shifting in obstetric and gynecological care: A survey of obstetrician-gynecologists across Japan.

ABSTRACT: To conduct a survey about task shifting in obstetric and gynecological care.A multivariate logistic regression analysis was conducted in Japanese hospitals using obstetrician-gynecologists (OB/GYNs) who answered that task shifting was rarely used at their working environment as the outcome variable and using their personal attributes (sex, age, type of medical institution employed at, and regional characteristics) as predictor variables. Opinions were gathered regarding promoting task shifting impact on individual work duties.Responses were collected from 919 OB/GYNs (49.9% women, 50.8% <40 years). Characteristics' analysis of 34.6% of OB/GYNs who thought that task shifting was hardly used indicated that it was used significantly more at private university hospitals (odds ratio 5.33, 95% confidence interval: 2.33-12.18) than at national university hospitals (odds ratio 3.54, 95% confidence interval: 1.67-7.51). "Transfer of patients (from operating rooms to the ward)" and "securing the contrast agent line" were the only items related to the task shifting status for individual work duties that were identified by most respondents, revealing that task shifting is not progressing. More than half and 9% of the OB/GYNs said that task shifting progression would improve and decline medical care quality, respectively. Overall, 46% and 24% of the respondents thought that task shifting could reduce working hours by ">1 hour, but <2 hours"/day and "<1 hour"/day, respectively.The current study confirmed that OB/GYNs working at university hospitals believe that task shifting is not progressing in university hospitals and that the working environment is poor. Even if task shifting reduces the number of working hours per day by 2 hours, the working hours of these physicians still exceed the criteria for death by overwork. Thus, further working hour reduction measures are needed in addition to task shifting, such as consolidation of medical institutions dealing with deliveries.To promote task shifting in obstetrical and gynecological care in Japan, it is necessary to continue promoting policy-based, institutional, and educational guidance.

The prediction of preeclampsia: the way forward.

Despite intensive investigation, we still cannot adequately predict, treat, or prevent preeclampsia. We have gained awareness that preeclampsia is a syndrome not a disease and is heterogeneous in its presentation and pathophysiology, which may indicate differing underlying phenotypes, and that the impact extends beyond pregnancy per se. Effects on the fetus and mother extend many years after pregnancy, as evidenced by fetal programming of adult disease and increased risk of the development of maternal cardiovascular disease. The increased occurrence of preeclampsia in women with preexisting risk factors suggests that the stress of pregnancy may expose subclinical vascular disease as opposed to preeclampsia damaging the vasculature. The heterogeneity of preeclampsia has blighted efforts to predict preeclampsia early in gestation and has thwarted success in attempts at therapy with treatments, such as low-dose aspirin or global antioxidants. There is a critical need to identify the phenotypes to enable their specific prediction and treatment. Such studies require considerably larger collections of patients than employed in past and current studies. This does not necessarily imply much larger patient numbers in single studies but can be facilitated by the ability to easily combine many smaller studies. This can be accomplished by agreeing on a priori standardized and harmonized clinical data and biospecimen collection across new studies. Such standards are being established by international groups of investigators. Leadership by international organizations, perhaps adopting a carrot and stick approach, to overcome investigator, institutional and funder reticence toward data sharing is required to ensure adoption of such standards. Future studies should include women in both low- and high-resource settings and employ social media and novel methods for data collection and analysis, including machine learning and artificial intelligence. The goal is to identify the pathophysiology underlying differing preeclampsia phenotypes, their successful prediction with the design, and the implementation of phenotype-specific therapies.

Experiences of maternity care among women at increased risk of preterm birth receiving midwifery continuity of care compared to women receiving standard care: Results from the POPPIE pilot trial.

BACKGROUND: Midwifery continuity of care models for women at low and mixed risk of complications have been shown to improve women's experiences of care. However, there is limited research on care experiences among women at increased risk of preterm birth. We aimed to explore the experiences of care among women with risk factors for preterm birth participating in a pilot trial (POPPIE) of a midwifery continuity of care model which included a specialist obstetric clinic. METHODS: A total of 334 pregnant women identified at increased risk of preterm birth were randomly allocated to either midwifery continuity of care (POPPIE group) or standard maternity care. Women in both groups were followed up at six-to-eight weeks postpartum and were invited to complete a postnatal survey either online or by post. An equal status exploratory sequential mixed method design was chosen to collect and analyse the quantitative postnatal survey data and qualitative interviews data. The postnatal survey included measures of social support, trust, perceptions of safety, quality of care, control during childbirth, bonding and quality of life. Categorical data were analysed with chi-squared tests and continuous data were analysed with t-tests and/or Mann-Whitney U test to measure differences in measures scores among groups. The qualitative interview data were subjected to a thematic framework analysis. Data triangulation brought quantitative and qualitative data together at the interpretation stage. FINDINGS: A total of 166 women completed the survey and 30 women were interviewed (90 and 16 in POPPIE group; 76 and 14 in standard group). We found survey respondents in the POPPIE group, compared to respondents in the standard group, were significantly more likely to report greater trust in midwives (Mann-Whitney U, p<0.0001), greater perceptions of safety during the antenatal care (t-test, p = 0.0138), have a particular midwife to contact when they needed during their pregnancy (t-test, p<0.0001) and the postnatal period (chi-squared, p<0.0001). They reported increased involvement in decisions regarding antenatal, intrapartum and postnatal care (t-test, p = 0.002; p = 0.008; p = 0.006 respectively); and greater postnatal support and advice about: feeding the baby (chi-squared, p<0.0001), handling, settling and looking after the baby (chi-squared, p<0.0001), baby's health and progress (chi-squared, p = 0.039), their own health and recovery (chi-squared, p = 0.006) and who to contact about any emotional changes (chi-squared, p = 0.005). There were no significant differences between groups in the reporting of perceptions of safety during birth and the postnatal period, concerns raised during labour and birth taken seriously, being left alone during childbirth at a time of worries, control during labour, bonding, social support, and physical and mental health related quality of life after birth. Results from qualitative interviews provided insight and depth into many of these findings, with women in the POPPIE group reporting more positive experiences of bonding towards their babies and more positive physical health postnatally. CONCLUSIONS: Compared with standard maternity care, women at increased risk of PTB who received midwifery continuity of care were more likely to report increased perceptions of trust, safety and quality of care.

Changes in the Frequency of Cesarean Delivery in Nulliparous Women in Labor in a Canadian Population, 1992-2018.

OBJECTIVE: To examine the relative contribution of changes in patient demographics and physician management to changes in the cesarean delivery rate in labor among nulliparous women. METHODS: We conducted a retrospective cohort study of 485,451 births to nulliparous women who experienced labor at or beyond 35 weeks of gestation in Alberta, Canada, from 1992 to 2018. The data were from a province-wide perinatal database. The primary outcome was cesarean delivery. Multivariate logistic regression and calculation of population attributable risk for identified risk factors were performed. RESULTS: The cesarean delivery rate increased from 12.5% in 1992 to 24% in 2018. The prevalence of maternal risk factors for cesarean delivery such as obesity, maternal age 35 years or older at delivery, and comorbidities increased over the study period. However, this did not account for the increase in cesarean delivery, because the frequency of cesarean delivery increased irrespective of risk status. Additionally, the population-attributable risk for each risk factor was stable across the study period. For example, for maternal age 35 years or older at delivery, the number of cesarean deliveries attributable to this factor (the population-attributable risk) was 0.9 per 100 deliveries in 1992-1998 and 1 per 100 in 2014-2018. The proportion of cesarean deliveries in which nonreassuring fetal status was the indication increased from 30.1% in 1992 to 51.1% in 2018. The absolute rate of cesarean delivery in the second stage of labor increased from 3.1% in 1992 to 5.9% in 2018. This was due to a significant increase, among those who entered the second stage, in cesarean delivery without a trial of forceps, from 2.5% in 1992 to 7.0% in 2018. CONCLUSION: The observed doubling of the rate of cesarean delivery in labor in first-time mothers was not driven by patient risk factors. Increases in the rate of cesarean delivery for nonreassuring fetal status and decreased operative vaginal deliveries were important factors.

Current Trends in Compensation for Fellowship in Minimally Invasive Gynecologic Surgery Graduates: A 6-Year Follow-Up.

STUDY OBJECTIVE: To present updated information regarding compensation patterns for Fellowship in Minimally Invasive Gynecologic Surgery (FMIGS)-graduated physicians in the United States beginning practice during the last 10 years, focusing on the variables that have an impact on differences in salary, including gender, fellowship duration, geographic region, practice setting, and practice mix. DESIGN: An online survey was sent to FMIGS graduates between March 15, 2019 and April 12, 2019. Information on physicians' demographics, compensation (on the basis of location, practice model, productivity benchmarks, academic rank, and years in practice), and attitudes toward fairness in compensation was collected. SETTING: Online survey. PARTICIPANTS: FMIGS graduates practicing in the United States. INTERVENTION: E-mail survey. MEASUREMENTS AND MAIN RESULTS: We surveyed 298 US FMIGS surgeons who had graduated during the last 10 years (2009-2018). The response rate was 48.7%. Most of the respondents were women (69%). Most of the graduates (84.8%) completed 2- or 3-year fellowship programs. After adjustment for inflation, the median starting salary for the first postfellowship job was $252 074 ($223 986-$279 983) (Table 1). The median time spent in the first job was 2.6 years, and the median total salary at the current year rose to $278 379.4 ($241 437-$350 976). The median salary for respondents entering a second postfellowship job started at $280 945 ($261 409-$329 603). Significantly lower compensation was reported for female FMIGS graduates in their initial postfellowship jobs and was consistently lower than for that of men over time. Most FMIGS graduates (59.7%) reported feeling inadequately compensated for their level of specialization. CONCLUSION: A trend toward higher self-reported salaries is noted for FMIGS graduates in recent years, with significant differences in compensation between men and women. Among obstetrics and gynecology subspecialists, FMIGS graduates earn significantly less than other fellowship-trained physicians, with median salaries that are lower than those of generalist obstetrics and gynecology physicians.

Impact of the COVID-19 Pandemic on Excess Perinatal Mortality and Morbidity in Israel.

OBJECTIVE: The 2020 COVID-19 pandemic has been associated with excess mortality and morbidity in adults and teenagers over 14 years of age, but there is still limited evidence on the direct and indirect impact of the pandemic on pregnancy. We aimed to evaluate the effect of the first wave of the COVID-19 pandemic on obstetrical emergency attendance in a low-risk population and the corresponding perinatal outcomes. STUDY DESIGN: This is a single center retrospective cohort study of all singleton births between February 21 and April 30. Prenatal emergency labor ward admission numbers and obstetric outcomes during the peak of the first COVID-19 pandemic of 2020 in Israel were compared with the combined corresponding periods for the years 2017 to 2019. RESULTS: During the 2020 COVID-19 pandemic, the mean number of prenatal emergency labor ward admissions was lower, both by daily count and per woman, in comparison to the combined matching periods in 2017, 2018, and 2019 (48.6 ± 12.2 vs. 57.8 ± 14.4, p < 0.0001 and 1.74 ± 1.1 vs. 1.92 ± 1.2, p < 0.0001, respectively). A significantly (p = 0.0370) higher rate of stillbirth was noted in the study group (0.4%) compared with the control group (0.1%). All study group patients were negative for COVID-19. Gestational age at delivery, rates of premature delivery at <28, 34, and 37 weeks, pregnancy complications, postdate delivery at >40 and 41 weeks, mode of delivery, and numbers of emergency cesarean deliveries were similar in both groups. There was no difference in the intrapartum fetal death rate between the groups. CONCLUSION: The COVID-19 pandemic stay-at-home policy combined with patient fear of contracting the disease in hospital could explain the associated higher rate of stillbirth. This collateral perinatal damage follows a decreased in prenatal emergency labor ward admissions during the first wave of COVID-19 in Israel. KEY POINTS: · Less obstetrical ER attendance is observed during the pandemic.. · There is a parallel increase in stillbirth rate.. · Stillbirth cases tested negative for COVID-19.. · Lockdown and pandemic panic are possible causes..

Differential Uptake of Telehealth for Prenatal Care in a Large New York City Academic Obstetrical Practice during the COVID-19 Pandemic.

During the coronavirus disease 2019 (COVID-19) pandemic in New York City, telehealth was rapidly implemented for obstetric patients. Though telehealth for prenatal care is safe and effective, significant concerns exist regarding equity in access among low-income populations. We performed a retrospective cohort study evaluating utilization of telehealth for prenatal care in a large academic practice in New York City, comparing women with public and private insurance. We found that patients with public insurance were less likely to have at least one telehealth visit than women with private insurance (60.9 vs. 87.3%, p < 0.001). After stratifying by borough, this difference remained significant in Brooklyn, one of the boroughs hardest hit by the pandemic. As COVID-19 continues to spread around the country, obstetric providers must work to ensure that all patients, particularly those with public insurance, have equal access to telehealth. KEY POINTS: · Telehealth for prenatal care is frequently utilized during the COVID-19 pandemic.. · Significant concerns exist regarding equity in access among lower-income populations.. · Women with public insurance in New York City were less likely to access telehealth for prenatal care..
