Quality measures in high-risk pregnancies: Executive Summary of a Cooperative Workshop of the Society for Maternal-Fetal Medicine, National Institute of Child Health and Human Development, and the American College of Obstetricians and Gynecologists

Society for Maternal-Fetal Medicine Special Statement: Clinical quality measures in obstetrics

This article provides an updated overview and critique of clinical quality measures relevant to obstetrical care. The history of the quality movement in the United States and the proliferation of quality metrics over the past quarter-century are reviewed. Common uses of quality measures are summarized: payment programs, accreditation, public reporting, and quality improvement projects. We present listings of metrics that are reported by physicians or hospitals, either voluntarily or by mandate, to government agencies, payers, "watchdog" ratings organizations, and other entities. The costs and other burdens of extracting data and reporting metrics are summarized. The potential for unintended adverse consequences of the use of quality metrics is discussed along with approaches to mitigating adverse consequences. Finally, some recent attempts to develop simplified core measure sets are presented, with the promise that the complex and burdensome quality-metric enterprise may improve in the near future.

Maternal and fetal/neonatal outcomes in pregnancy, delivery and postpartum following bariatric surgery and comparison with pregnant women with obesity: a study protocol for a prospective cohort

BACKGROUND

Being obese can lead to various complications during pregnancy, such as Gestational Diabetes Mellitus (GDM), pregnancy induced hypertension (PIH), Pre-Eclampsia (PE), and Large Gestational Age (LGA). Although bariatric surgery is an effective way to treat obesity, it can also result in complications and may be linked to having small for gestational age (SGA) babies. This cohort study protocol aims to compare the maternal and fetal/neonatal outcomes of two groups of Iranian pregnant women: those who have undergone bariatric surgery and those who are obese but have not had bariatric surgery.

METHODS

In this study Pregnant women (< 14 weeks' gestation) (n = 38 per group) are recruited either from one of the obesity clinic (exposure group = with a history of bariatric surgery) or primary healthcare clinics in Tehran city (comparison group = pregnant women with obesity and and no history of bariatric surgery). Dietary intake and nutrient status are assessed at < 14, 28, and 36 weeks. Maternal and fetal/neonatal outcomes are compared between the two groups, including gestational diabetes, preeclampsia, preterm labor, intrauterine growth restriction, severe nausea and vomiting, abortion, placenta previa and abruption, venous thrombosis, vaginal bleeding, cesarean delivery, meconium aspiration, and respiratory distress. Maternal serum levels of ferritin, albumin, zinc, calcium, magnesium, selenium, copper, vitamins A, B9, B12, and 25-hydroxy Vit D are checked during 24th to 28th weeks. Maternal and neonatal outcomes, including height, weight, head circumference, fetal abnormality, infection, small or large fetus, low birth weight, macrosomia, NICU admission, and total weight gain during pregnancy, are measured at birth. Maternal and offspring outcomes, including weight, height, head circumference, total weight gain during pregnancy, newborn diseases, postpartum bleeding, breastfeeding, and related problems, are assessed 6 weeks after delivery. Child's weight, height, and head circumference are followed at 2, 4, 6, 8, 10, and 12 months after birth. Maternal stress, anxiety, and depression are assessed with the DASS-21 questionnaire, and physical activity is evaluated using the PPAQ questionnaire in the first and third trimesters.

DISCUSSION

By assessing the levels of micronutrients in the blood of pregnant women along with the evaluation of pregnancy outcomes, it is feasible to gain a more accurate understanding of how bariatric surgery affects the health and potential complications for both the mother and the fetus/newborn. This information can help specialists and patients make more informed decisions about the surgery. Additionally, by examining issues such as stress, anxiety, and depression in women undergoing surgery, this study can contribute to recognizing these problems, which can also affect pregnancy outcomes.

Electronic Reminder to Transition Care After Hypertensive Disorders of Pregnancy: A Randomized Controlled Trial

OBJECTIVE

Scalable interventions are needed to improve preventive care for those with increased cardiovascular disease (CVD) risk identified during pregnancy. We hypothesized that an automated reminder message for clinicians (nudge) would increase counseling at the postpartum visit on patient transitions of care.

METHODS

We conducted a single-center, randomized controlled trial including birthing people with a hypertensive disorder of pregnancy evaluating a nudge compared with usual care. The nudge, including counseling phrases and patient-specific information on hypertensive diagnosis, was sent to the obstetric clinician through the electronic medical record up to 7 days before the postpartum visit. The primary outcome was documentation of counseling on transitions of care to primary care or cardiology. Secondary outcomes were documentation of CVD risk, use of counseling phrases, and preventive care visit within 6 months. A sample size of 94 per group (n=188) was planned to compare the nudge intervention with usual care; given the anticipated loss to follow-up, the sample size was increased to 222. Intention-to-treat analyses were performed, with P <.05 considered significant.

RESULTS

From February to June 2021, 392 patients were screened, and 222 were randomized and analyzed. Of these, 205 (92.3%) attended a postpartum visit. Groups were similar, but more women in the usual care group had diabetes (16.1% vs 6.7%, P =.03). After adjustment for diabetes, patients in the nudge group were more likely to have documented counseling on transitions of care (38.8% vs 26.2%, adjusted relative risk [aRR] 1.53, 95% CI 1.02-2.31), CVD risk (21.4% vs 8.4%, aRR 2.57, 95% CI 1.20-5.49), and use of aspirin in a future pregnancy (14.3% vs 1.9%, aRR 7.49, 95% CI 1.66-33.93). Counseling phrases were used more often in the nudge group (11.2% vs 0.9%, aRR 12.27, 95% CI 1.50-100.28). Preventive care visit attendance did not differ by group (22.1% vs 24.6%, aRR 0.91, 95% CI 0.57-1.47).

CONCLUSION

A timely electronic reminder to obstetric clinicians improved counseling about transitions of care after hypertensive disorders of pregnancy but did not result in increased preventive care visit attendance.

Postpartum hemorrhage protocols and benchmarks: improving care through standardization

Postpartum hemorrhage remains a leading cause of maternal morbidity and mortality in the United States. Several state maternal morbidity and mortality committees have reviewed areas of opportunity concerning postpartum hemorrhage management and found that common patterns include delays in recognition and response to hemorrhage. Hospital systems and state perinatal quality collaboratives have found that comprehensive, interdisciplinary response to postpartum hemorrhage care improves patient outcomes and, in some instances, reduces racial disparities. A key component of this focus involves the implementation of stage-based hemorrhage protocols for postpartum hemorrhage management. Stage-based hemorrhage protocols are designed to reduce delays in the diagnosis and management and avoid the pitfalls of cognitive biases. These protocols are complex, and their effectiveness is tied to the quality of their implementation. Systematic benchmarking and development of quality metrics for adherence to postpartum hemorrhage bundles would be expected to improve clinical outcomes, but evidence regarding the effectiveness of this practice in the literature is limited. Here, key features of stage-based interventions and evidence regarding the use of quality metrics for postpartum hemorrhage protocol adherence have been outlined.

Defining a Cesarean Delivery Rate for Optimizing Maternal and Neonatal Outcomes

After the global cesarean delivery rate nearly doubled between 2000 and 2015, cesarean deliveries now account for nearly one third of births in the United States. Although rates have plateaued, the high national cesarean delivery rate has garnered criticism from both lay and academic communities because it has not been associated with improvements in maternal or neonatal outcomes. Efforts are underway to lower the cesarean delivery rate through implementation of hospital-level and national guidelines. However, the cesarean delivery rate that optimizes maternal and neonatal outcomes is not known. Defining a cesarean delivery rate that optimizes perinatal outcomes and reduces morbidity seems simple. However, there are a host of challenges to such a task, including determining the outcomes that are most meaningful to use, deciding the population that should define the rate, and incorporating person-centered decision making, given that people place different value on different outcomes. Rather than a "call" for cesarean delivery rate reductions of a specific and arbitrary magnitude, we need further attention to defining an evidence-based optimal target. This commentary summarizes current national and international cesarean delivery rate targets, discusses the challenges of identifying an evidence-based national cesarean delivery rate target, and explores future considerations for best defining a cesarean delivery rate target.

Society for Maternal-Fetal Medicine Special Statement: Quality metrics for optimal timing of antenatal corticosteroid administration

Preterm birth is a leading cause of perinatal morbidity and mortality. Antenatal corticosteroid administration before preterm birth reduces the risks of perinatal death, respiratory morbidity, necrotizing enterocolitis, and intraventricular hemorrhage and reduces the costs of perinatal care. Antenatal corticosteroids are optimally effective when administered within 7 days before preterm birth. However, only 20% to 40% of early preterm infants receive antenatal corticosteroids within 7 days before birth, in part because it is difficult to predict the precise timing of preterm birth. Until 2020, The Joint Commission had a Perinatal Care quality metric measuring the rate of antenatal corticosteroid administration at any time before early preterm birth. This metric incentivized providers to use antenatal corticosteroids liberally. The Joint Commission retired the metric in 2020 after the rate reached more than 97% in The Joint Commission-accredited hospitals. However, the metric did not evaluate whether the timing of antenatal corticosteroid administration was optimal, that is, within 7 days of birth. A 2016 multistakeholder Cooperative Workshop recommended the development of a new quality metric to assess the rate of optimally timed antenatal corticosteroids among early preterm births. In this statement, we outline proposed specifications for such a metric and discuss potential uses, advantages, limitations, and barriers. Furthermore, we propose a balancing metric that tracks the percentage of patients treated with antenatal corticosteroids who ultimately give birth at term. We suggest that the use of these new metrics may incentivize more conservative antenatal corticosteroid timing, which could, in turn, lead to meaningfully improved outcomes for preterm neonates.

Society for Maternal-Fetal Medicine Special Statement: Quality metric for timely postpartum follow-up after severe hypertension

Hypertensive disorders of pregnancy are a leading cause of maternal morbidity and mortality. Because postpartum exacerbation of severe hypertension is common, the American College of Obstetricians and Gynecologists recommends that patients with severe hypertension during the childbirth hospitalization be seen within 72 hours after discharge. In this statement, the Society for Maternal-Fetal Medicine proposes a uniform metric reflecting the rate of timely postpartum follow-up of patients with severe hypertension. The metric is designed to be measured using automated calculations based on billing codes derived from claims data. The metric can be used in quality improvement projects to increase the rate of timely follow-up in patients with severe hypertension during the childbirth hospitalization. Suggested steps for implementing such a project are outlined.

The Safety of Low-Dose Aspirin on the Mode of Delivery: Secondary Analysis of the Effect of Aspirin in Gestation and Reproduction Randomized Controlled Trial

OBJECTIVE

This study aimed to examine whether prenatal low-dose aspirin (LDA) therapy affects risk of cesarean versus vaginal delivery.

STUDY DESIGN

This study is a secondary analysis of the randomized clinical effects of aspirin in gestation and reproduction (EAGeR) trial. Women received 81-mg daily aspirin or placebo from preconception to 36 weeks of gestation. Mode of delivery and obstetric complications were abstracted from records. Log-binomial regression models estimated relative risk (RR) of cesarean versus vaginal delivery. Data were analyzed among the total preconception cohort, as well as restricted to women who had a live birth.

RESULTS

Among 1,228 women, 597 had a live birth. In the intent-to-treat analysis, preconception-initiated LDA was not associated with risk of cesarean (RR = 1.02; 95% confidence interval [CI]: 0.98-1.07) compared with placebo. Findings were similar in just women with a live birth and when accounting prior cesarean delivery and parity.

CONCLUSION

Preconception-initiated daily LDA was not associated with mode of delivery among women with one to two prior losses.

KEY POINTS

· Aspirin was not associated with risk of cesarean section.. · Aspirin was not associated with mode of delivery.. · No increased risk of bleeding with use of aspirin..

Society for Maternal-Fetal Medicine Special Statement: A quality metric for evaluating timely treatment of severe hypertension

Severe hypertension in pregnancy is a medical emergency. Although expeditious treatment within 30 to 60 minutes is recommended to reduce the risk of maternal death or severe morbidity, treatment is often delayed by >1 hour. In this statement, we propose a quality metric that facilities can use to track their rates of timely treatment of severe hypertension. We encourage facilities to adopt this metric so that future reports from different facilities will be based on a uniform definition of timely treatment.

Benchmarking Cesarean Delivery Rates using Machine Learning-Derived Optimal Classification Trees

OBJECTIVE

To establish a case-adjusted hospital-specific performance evaluation tool using machine learning methodology for cesarean delivery.

DATA SOURCES

Secondary data were collected from patients between 1/1/2015-2/28/2018 using a hospital's "Electronic Data Warehouse" database from Illinois, USA.

STUDY DESIGN

The machine learning methodology of Optimal Classification Trees (OCT's) was used to predict cesarean delivery rate by physician group, thereby establishing the case-adjusted benchmarking standards in comparison to the overall hospital cesarean delivery rate. Outcomes of specific patient populations of each participating practice were predicted, as if each were treated in the overall hospital environment. The resulting OCTs estimate physician group expected cesarean delivery outcomes, both aggregate and in specific clinical situations.

DATA COLLECTION/EXTRACTION METHODS

12,841 singleton, vertex, term deliveries, cared for by practices with ≥50 births.

PRINCIPAL FINDINGS

The overall rate of cesarean delivery was 18.6% (n = 2384), with a range of 13.3%-33.7% amongst 22 physician practices. An optimal decision tree was used to create a prediction model for the overall hospital which defined 23 patient cohorts, divided by 46 nodes. The model's performance for prediction of cesarean delivery is as follows: area under the curve- 0.73, sensitivity- 98.4%, specificity- 16.1%, positive predictive value 83.7%, negative predictive value 70.6%. Comparisons with the overall hospital's specific-case adjusted benchmark groups revealed that several groups outperformed the overall hospital and some practice groups underperformed in comparison to the overall hospital.

CONCLUSIONS

OCT benchmarking can assess physician practice specific case-adjusted performance, both overall and clinical situation specific, and can serve as a valuable tool for hospital self-assessment and quality improvement. This article is protected by copyright. All rights reserved.

Volume as an Indicator for Outcomes for Severe Maternal Morbidity in the Military Health System

BACKGROUND

Maternal obstetric morbidity is a growing concern in the USA, where rates of maternal morbidity exceed Europe and most developed countries. Prior studies have found that obstetric case volume affects maternal morbidity, with low-volume facilities having higher rates of morbidity. However, these studies were done in civilian healthcare systems that are different from the Military Health System (MHS). This study evaluates whether obstetric case volume impacts severe maternal morbidity (SMM) in military hospitals located in the continental United States.

METHODS

This cross-sectional study included all military treatment facilities (MTFs) (n = 35) that performed obstetric deliveries (n = 102,959) from October 2015 to September 2018. Data were collected from the MHS Data Repository and identified all deliveries for the study time period. Severe maternal morbidity was defined by the Centers for Disease Control. The 30-day readmission rates were also included in analysis. Military treatment facilities were separated into volume quartiles for analysis. Univariate logistic regressions were performed to determine the impact of MTF delivery volume on the probability of SMM and 30-day maternal readmissions.

RESULTS

The results for all regression models indicate that the MTF delivery volume had no significant impact on the probability of SMM. With regard to 30-day maternal readmissions, using the upper middle quartile as the comparison group due to the largest number of deliveries, MTFs in the lower middle quartile and in the highest quartile had a statistically significant higher likelihood of 30-day maternal readmissions.

CONCLUSION

This study shows no difference in SMM rates in the MHS based on obstetric case volume. This is consistent with previous studies showing differences in MHS patient outcomes compared to civilian healthcare systems. The MHS is unique in that it provides families with universal healthcare coverage and access and provides care for approximately 40,000 deliveries annually. There may be unique lessons on volume and outcomes in the MHS that can be shared with healthcare planners and decision makers to improve care in the civilian setting.

Term Singleton Vertex Cesarean Birth Rates in the Military Health System

Cesarean births have increased in the United States, accounting for approximately one-third of all births. There is concern that cesarean birth is overused, due to the wide variation in rates geographically and at different institutions within the same region. Despite the rising rate, there has not been an improvement in maternal or neonatal outcomes. Consequently, the American College of Obstetricians and Gynecologists and the Society for Maternal-Fetal Medicine published recommendations aimed at the safe prevention of primary cesarean births in 2014. The purpose of this project was to identify the term singleton vertex cesarean birth rates in the Military Health System's hospitals; to compare the Military Health System's rate of term singleton vertex cesarean birth to published benchmarks; and to compare term singleton vertex cesarean birth rates over time and among facilities within the Military Health System to determine whether variation existed. This was a retrospective review of aggregate data reported by the National Perinatal Information Center. Data were analyzed over 9 years at 2-year intervals from 2011 through 2019 inclusively. The Military Health System exceeded national benchmarks for term singleton vertex cesarean birth rates and had less variation over time and among facilities.

Postpartum counseling in women with hypertensive disorders of pregnancy

BACKGROUND

Hypertensive disorders of pregnancy are associated with increased cardiovascular disease risk across the lifespan. The American College of Obstetricians and Gynecologists and the American Heart Association emphasize the postpartum period as an important opportunity to identify and intervene women at high risk of future cardiovascular disease.

OBJECTIVE

This study aimed to determine the proportion of women with documented counseling on risks and transitions of care after hypertensive disorders of pregnancy at the postpartum visit.

STUDY DESIGN

This was a retrospective longitudinal descriptive study of women with hypertensive disorders of pregnancy who were enrolled in a text-based blood pressure program from September 2018 to February 2019. We abstracted counseling in the discharge summary and postpartum note from the electronic medical record. The primary outcome was counseling at the postpartum visit defined as documentation of (1) follow-up with primary care or cardiology, (2) risk of cardiovascular disease, or (3) recommendation for aspirin in a future pregnancy. We assessed demographic and clinical factors that may influence counseling through multivariable logistic regression. We also compared the proportion of women counseled on hypertensive disorders of pregnancy vs contraception and glucose tolerance tests at the postpartum visit.

RESULTS

Of 320 eligible women, most women had gestational hypertension or preeclampsia without severe features (64%). Postpartum visits were scheduled in our hospital system for 284 women, of whom 253 attended (89%). Documented counseling occurred for 62 women (25%). Counseling on follow-up with primary care or cardiology, cardiovascular disease risk, and aspirin in future pregnancies was documented for 51 (20%), 15 (6%), and 1 (0.4%), respectively. Only 1 woman had documented counseling on all 3 components. In multivariable analysis, black race remained an independent factor that increased the likelihood of counseling on hypertensive disorders of pregnancy (adjusted odds ratio, 2.77; 95% confidence interval, 1.32-5.83). Women were significantly less likely to be counseled on hypertensive disorders of pregnancy than on contraceptives (99%, P<.001) or glucose tolerance testing after gestational diabetes mellitus (79%, P<.001).

CONCLUSION

Postpartum counseling on hypertensive disorders of pregnancy merits urgent improvement efforts among obstetrical care providers.

Short-Term Effect of MgSO4 on the Expression of NRG-ErbB, Dopamine, GABA, and Glutamate Systems in the Fetal Rat Brain

MgSO₄ has been used for the past two decades as neuroprotective treatment in a variety of preterm conditions. Despite the putative advantages of MgSO₄ as a neuroprotective agent in the preterm brain, the short- and long-term molecular function of MgSO₄ as a neuroprotective agent has not been fully elucidated. Neuregulin (NRG1)-ErbB4 signaling plays a critical role in embryonic brain development, in the biology of dopaminergic, GABAergic, and glutamatergic systems. We hypothesize that this pathway may be associated with the neuroprotective role of MgSO₄. The current study aims to investigate the ability of MgSO₄ to modulate the normal developing expression pattern of selected genes related to the NRG1-ErbB, dopaminergic, GABAergic, and glutamatergic systems. We demonstrate that overall short-term treatment of dam rats with MgSO₄ affects the expression of fetal brain NRG1, NRG3, ErbB4, GAD67, tyrosine hydroxylase (TH), dopamine D₂ and D₁ receptors, GluN1, and GluN2B. More specifically, the administration of MgSO₄ alters the expression of NRG-ErbB, GAD67, TH, and D2R at early gestation day 16 (GD16) regardless of the activation of the maternal immune system by lipopolysaccharide (LPS). Our data suggest that MgSO₄ treatment may affect the expression of major neuronal systems and pathways mostly at an early gestation day. These changes might be an initial clue (foundation stone) in the molecular mechanism that underlies the beneficial effect of MgSO₄ as a neuroprotective agent for the developmental brain.

Special statement: Proposed quality metrics to assess accuracy of prenatal detection of congenital heart defects

Congenital heart defects are a leading cause of neonatal morbidity and mortality. Accurate prenatal diagnosis of congenital heart defects can reduce morbidity and mortality by improving prenatal care, facilitating predelivery pediatric cardiology consultation, and directing delivery to facilities with resources to manage the complex medical and surgical needs of newborns with congenital heart defects. Unfortunately, less than one half of congenital heart defect cases are detected prenatally, resulting in lost opportunities for counseling, shared decision-making, and delivery at an appropriate facility. Quality improvement initiatives to improve prenatal congenital heart defects detection depend on the ability to measure the rate of detection at the level of providers, facilities, or populations, but no standard metric exists for measuring the detection of congenital heart defects at any level. The need for such a metric was recognized at a Cooperative Workshop held at the 2016 Annual Meeting of the Society for Maternal-Fetal Medicine, which recommended the development of a quality metric to assess the rate of prenatal detection of clinically significant congenital heart defects. In this paper, we propose potential quality metrics to measure prenatal detection of critical congenital heart defects, defined as defects with a high rate of morbidity or mortality or that require surgery or tertiary follow-up. One metric is based on a retrospective approach, assessing whether postnatally diagnosed congenital heart defects had been identified prenatally. Other metrics are based on a prospective approach, assessing the sensitivity and specificity of prenatal diagnosis of congenital heart defects by comparing prenatal ultrasound findings with newborn findings. Potential applications, limitations, challenges, barriers, and value for both approaches are discussed. We conclude that future development of these metrics will depend on an expansion of the International Classification of Diseases system to include specific codes that distinguish fetal congenital heart defects from newborn congenital heart defects and on the development of record systems that facilitate the linkage of fetal records (in the maternal chart) with newborn records.

Prior authorization and its impact on access to obstetric ultrasound

Prior authorization is a process requiring health care providers to obtain advance approval from a payer before a patient undergoes a procedure for the study to be covered. Prior authorization was introduced to decrease overutilization of ultrasound procedures. However, it has led to unanticipated consequences such as impeding access to obstetric imaging, increased administrative overhead without reimbursement, and contribution to physician frustration and burnout. Payers often use intermediary radiology benefit management companies without providing specialty-specific review in a timely manner as is requisite when practicing high-risk obstetrics. This article proposes a number of potential solutions to this problem: (1) consider alternative means to monitor overutilization; (2) create and evaluate data regarding providers in the highest utilization; (3) continue to support and grow the educational efforts of speciality societies to publish clinical guidelines; and (4) emphasize the importance of practicing evidence-based medicine. Understanding that not all health plans may be willing or able to collaborate with health care providers, we encourage physicians to advocate for policies and legislation to limit the implementation of prior authorization within their own states.

Brief Report: Markers of Spontaneous Preterm Delivery in Women Living With HIV: Relationship With Protease Inhibitors and Vitamin D

BACKGROUND

Women living with HIV (WLHIV) have increased risk of spontaneous preterm delivery (SPTD). We sought to identify plasma predictors of SPTD and their correlations with factors that increase the risk of SPTD, such as vitamin D deficiency and use of protease inhibitors.

DESIGN

Plasma was obtained from 103 WLHIV with SPTD (≤35 weeks gestation) and 205 controls with term deliveries (TDs; ≥37 weeds) matched to cases 2:1 by race and gestational age at blood draw. TNFα, IFNγ, IL6, IL8, IL1β, IL18, IL17, granulocyte colony stimulating factor (GCSF), MCP1, IP10, sIL2Rα, sCD14, vascular endothelial factor a, monocyte colony stimulation factor, GROα, MMP9, IL10, TGFβ, sCTLA4, and eicosanoids were compared between cases adjusting for known SPTD risk factors.

RESULTS

Participants had similar demographic characteristics, but cases had higher plasma HIV RNA, lower CD4 cells, and more advanced HIV disease compared with controls. High sIL2Rα was associated with increased risk of SPTD. High sCD14, GCSF, PGF2α, and 5-HEPE were marginally associated with increased risk of SPTD. Women who initiated protease inhibitors-containing antiretroviral treatment before or during the first trimester had higher levels of GCSF and 5-HEPE compared with women without such exposure before plasma collection. Vitamin D insufficiency was associated with higher inflammatory sCD14 and PGF2α, and lower anti-inflammatory 5-HEPE.

CONCLUSIONS

The best plasma predictor of SPTD in WLHIV was sIL2Rα, a marker of T-cell activation. Markers of monocyte activation and eicosanoids were marginally increased in WLHIV and SPTD, suggesting that they may also play a role in the pathogenesis of this disorder.

Safely lowering the emergency Cesarean and operative vaginal delivery rates using the Fetal Reserve Index

Objective: The cardiotocograph (CTG) or electronic fetal monitoring (EFM) was developed to prevent fetal asphyxia and subsequent neurological injury. From a public health perspective, it has failed these objectives while increasing emergency operative deliveries (emergency operative deliveries (EODs) - emergency cesarean delivery or operative vaginal delivery) for newborns, who in retrospect, actually did not require the assistance. EODs increase the risks of complications and stress for patients, families, and medical personnel. A safe reduction in the need for EOD will likely reduce both the overall Cesarean section rate as well as the risk of fetal neurological injury during labor to which it is related. We have developed the fetal reserve index (FRI), which is more comprehensive than CTG as a new screening method for early identification of the fetus at-risk of both neurological harm and the need to "rescue" by means of an EOD. Here, we compare prospectively the need for EOD in two groups of parturients undergoing a trial of labor at term. One group was managed conventionally, the other by the principles of the FRI.Study design: We compared the need for EOD of 800 parturients with singleton cases undergoing a trial of labor at term entering with normal CTG patterns (ACOG category 1). Patients were either treated routinely (400 - "early cases") or in a second group seen later actively managed using the principles of the FRI (400 - "late cases"). The FRI includes measurements of five components of the CTG: rate, variability, decelerations, accelerations, and abnormal uterine activity combined with the presence of medical, obstetrical, and fetal risk factors. The 8-point metric categorizes cases as "green", "yellow", and "red" with the latter being at risk.Results: All 800 patients delivered babies, who were discharged in the usual time course with no untoward outcomes noted. The incidence of red zone scores was comparable in the two groups (≈25%), but the use of intrauterine resuscitation (IR) when reaching the red zone in the late group (47%) was more than double the incidence in the early group (20%) (p < .001). Despite (or because of) this, EODs were significantly reduced in the late group, from 17.3 to 4.0% (p < .001). Further, the late group spent less time in the red zone without increasing overall time in labor. Overall, EOD cases averaged >1 h in the red zone versus 0.5 h for non-EODs.Conclusions: The FRI may provide a metric to reduce EODs and by extension also reduce the risks of both cesarean delivery and adverse fetal/neonatal outcomes. The safe avoidance of EOD would seem to be an important metric to assess the quality of intrapartum management. This study represents the first attempt to apply the principles of the FRI "live" for the concurrent management of patients during labor. These promising results, if confirmed, in larger sample sizes, set the stage for our computerization of the FRI for widespread study. Benefits appear to come from identification and early, conservative management of fetal deterioration before the need to "rescue" the fetus by EOD.

Developing a set of consensus indicators to support maternity service quality improvement: using Core Outcome Set methodology including a Delphi process

OBJECTIVE

To develop a core metric set to monitor the quality of maternity care.

DESIGN

Delphi process followed by a face-to-face consensus meeting.

SETTING

English maternity units.

POPULATION

Three representative expert panels: service designers, providers and users.

MAIN OUTCOME MEASURES

Maternity care metrics judged important by participants.

METHODS

Participants were asked to complete a two-phase Delphi process, scoring metrics from existing local maternity dashboards. A consensus meeting discussed the results and re-scored the metrics.

RESULTS

In all, 125 distinct metrics across six domains were identified from existing dashboards. Following the consensus meeting, 14 metrics met the inclusion criteria for the final core set: smoking rate at booking; rate of birth without intervention; caesarean section delivery rate in Robson group 1 women; caesarean section delivery rate in Robson group 2 women; caesarean section delivery rate in Robson group 5 women; third- and fourth-degree tear rate among women delivering vaginally; rate of postpartum haemorrhage of ≥1500 ml; rate of successful vaginal birth after a single previous caesarean section; smoking rate at delivery; proportion of babies born at term with an Apgar score <7 at 5 minutes; proportion of babies born at term admitted to the neonatal intensive care unit; proportion of babies readmitted to hospital at <30 days of age; breastfeeding initiation rate; and breastfeeding rate at 6-8 weeks.

CONCLUSIONS

Core outcome set methodology can be used to incorporate the views of key stakeholders in developing a core metric set to monitor the quality of care in maternity units, thus enabling improvement.

TWEETABLE ABSTRACT

Achieving consensus on core metrics for monitoring the quality of maternity care.

Quality Improvement in Perinatal Medicine and Translation of Preterm Birth Research Findings into Clinical Care

Billions of dollars are spent yearly in perinatal medicine on studies designed to improve outcomes for mothers and their neonates. However, implementing research findings is challenging and imperfect. Strategies for implementation must be multifaceted and comprehensive. These implementation challenges extend to, and are often greater in, translational and basic science research. The purpose of this review is to discuss current challenges in the provision of quality perinatal and neonatal medical care, particularly those related to preterm birth, and provide examples of prematurity-related perinatal quality collaborative initiatives. Finally, the authors review considerations in implementing both clinical and translational/basic science prematurity research.
