Maternal Group B Streptococcus Prophylaxis Improvement using an Electronic Medical Record Dynamic Order Set.

OBJECTIVE: To develop and implement a Group B Streptococcal (GBS) dynamic order set to improve adherence to the American College of Obstetricians and Gynecologists/Centers for Disease Control and Prevention (ACOG/CDC) guidelines. STUDY DESIGN: A team of information technology and clinical experts developed a dynamic order block. The content was patterned after the CDC "Prevent GBS" mobile app. It was then embedded in the labor and delivery/induction order set and piloted at a single high-volume obstetric unit. Following the pilot and incorporation of the 2019 ACOG update of the CDC guidelines, the order set was rolled out in five additional hospitals within a region of a large health system. Information on GBS prophylaxis performance before and after implementation was available for the pilot site and four of the additional hospitals. Information before implementation was obtained electronically from electronic medical record (EMR) laboratory and pharmacy data and supplemented by manual chart review. Postimplementation data were obtained from discrete order set EMR data elements. Adherence to the guidelines before and after were compared using chi-squared test. RESULTS: There were 7,114 deliveries before implementation and 4,502 after implementation. Preterm delivery occurred in 6.8 and 6.9%, respectively. There was an increase in appropriate treatment of preterm patients (positive and unknown GBS) delivering after implementation (88.7-99.1%, p < 0.001). More patients were reported to have a penicillin allergy before implementation than after implementation (14.7 vs. 11.1%, respectively, p = 0.01). Associated changes in therapy noted after implementation included a nonsignificant decrease in the proportion reporting a high-risk allergy (50.3 vs. 41.9%, p = 0.18), an increase in the appropriate use of clindamycin and vancomycin (64.4 vs. 92.3%, p < 0.001) and a decrease in clindamycin use in those without sensitivity testing. CONCLUSION: Routine universal use of a dynamic admission labor/induction order set was associated with high and improved adherence to GBS prophylaxis guidelines. KEY POINTS: · Lapses in GBS prophylaxis are associated with early-onset GBS disease.. · Preterm delivery and penicillin allergic patients are commonly associated with lapses in prophylaxis.. · Dynamic EMR order set use can improve adherence to clinical guidelines..

Electronic Fetal Monitoring Credentialing Examination: The First 4000.

Objective Recognized variability in fetal heart rate interpretation led the Perinatal Quality Foundation (PQF) to develop a credentialing exam. We report an evaluation of the 1st 4000 plus PQF Fetal Monitoring Credentialing (FMC) exams. Study Design The PQF FMC exam is an online assessment for obstetric providers and nurses. The exam contains two question types: traditional multiple-choice evaluating knowledge and Script Concordance Theory (SCT) evaluating judgment. Reliability was measured through McDonald's Total Omega and Cronbach's Alpha. Pearson's correlations between knowledge and judgment were measured. Results From February 2014 through September 2018, 4,330 different individuals took the exam. A total of 4,057 records were suitable for reliability analysis: 2,105 (52%) physicians, 1,756 (43%) nurses, and 196 (5%) certified nurse midwives (CNMs). As a measure of test reliability, total Omega was 0.80 for obstetric providers and 0.77 for nurses. There was only moderate correlation between the knowledge scores and judgment scores for obstetric providers (0.38) and for nurses (0.43). Conclusion The PQF FMC exam is a reliable, valid assessment of both Electronic Fetal Monitoring (EFM) knowledge and judgment. It evaluates essential EFM skills for the establishment of practical credentialing. It also reports modest correlation between knowledge and judgment scores, suggesting that knowledge alone does not assure clinical competency.

Shifting Patterns in Cesarean Delivery Scheduling and Timing in Oregon before and after a Statewide Hard Stop Policy.

OBJECTIVES: To assess the use and timing of scheduled cesareans and other categories of cesarean delivery and the prevalence of neonatal morbidity among cesareans in Oregon before and after the implementation of Oregon's statewide policy limiting elective early deliveries. DATA SOURCES: Oregon vital statistics records, 2008-2013. STUDY DESIGN: Retrospective cohort study, with multivariable logistic regression, regression controlling for time trends, and interrupted time series analyses, to compare the odds of different categories of cesarean delivery and the odds of neonatal morbidity pre- and postpolicy. DATA COLLECTION/EXTRACTION METHODS: We analyzed vital statistics data on all term births in Oregon (2008-2013), excluding births in 2011. PRINCIPAL FINDINGS: The odds of early-term scheduled cesareans decreased postpolicy (adjusted odds ratio [aOR], 0.70; 95 percent confidence interval [CI], 0.66-0.74). In the postpolicy period, there were mixed findings regarding assisted neonatal ventilation and neonatal intensive care unit admission, with regression models indicating higher postpolicy odds in some categories, but lower postpolicy odds after controlling for time trends. CONCLUSIONS: Oregon's hard stop policy limiting elective early-term cesarean delivery was associated with lower odds of cesarean delivery in the category of women who were targeted by the policy; more research is needed on impact of such policies on neonatal outcomes.

Oregon's Hard-Stop Policy Limiting Elective Early-Term Deliveries: Association With Obstetric Procedure Use and Health Outcomes.

OBJECTIVE: To evaluate the association of Oregon's hard-stop policy limiting early elective deliveries (before 39 weeks of gestation) and the rate of elective early-term inductions and cesarean deliveries and associated maternal-neonatal outcomes. METHODS: This was a population-based retrospective cohort study of Oregon births between 2008 and 2013 using vital statistics data and multivariable logistic regression models. Our exposure was the Oregon hard-stop policy, defined as the time periods prepolicy (2008-2010) and postpolicy (2012-2013). We included all term or postterm, cephalic, nonanomalous, singleton deliveries (N=181,034 births). Our primary outcomes were induction of labor and cesarean delivery at 37 or 38 weeks of gestation without a documented indication on the birth certificate (ie, elective early term delivery). Secondary outcomes included neonatal intensive care unit admission, stillbirth, macrosomia, chorioamnionitis, and neonatal death. RESULTS: The rate of elective inductions before 39 weeks of gestation declined from 4.0% in the prepolicy period to 2.5% during the postpolicy period (P<.001); a similar decline was observed for elective early-term cesarean deliveries (from 3.4% to 2.1%; P<.001). There was no change in neonatal intensive care unit admission, stillbirth, or assisted ventilation prepolicy and postpolicy, but chorioamnionitis did increase (from 1.2% to 2.2%, P<.001; adjusted odds ratio 1.94, 95% confidence interval 1.80-2.09). CONCLUSIONS: Oregon's statewide policy to limit elective early-term delivery was associated with a reduction in elective early-term deliveries, but no improvement in maternal or neonatal outcomes.

Cell-free DNA analysis for noninvasive examination of trisomy.

BACKGROUND: Cell-free DNA (cfDNA) testing for fetal trisomy is highly effective among high-risk women. However, there have been few direct, well-powered studies comparing cfDNA testing with standard screening during the first trimester in routine prenatal populations. METHODS: In this prospective, multicenter, blinded study conducted at 35 international centers, we assigned pregnant women presenting for aneuploidy screening at 10 to 14 weeks of gestation to undergo both standard screening (with measurement of nuchal translucency and biochemical analytes) and cfDNA testing. Participants received the results of standard screening; the results of cfDNA testing were blinded. Determination of the birth outcome was based on diagnostic genetic testing or newborn examination. The primary outcome was the area under the receiver-operating-characteristic curve (AUC) for trisomy 21 (Down's syndrome) with cfDNA testing versus standard screening. We also evaluated cfDNA testing and standard screening to assess the risk of trisomies 18 and 13. RESULTS: Of 18,955 women who were enrolled, results from 15,841 were available for analysis. The mean maternal age was 30.7 years, and the mean gestational age at testing was 12.5 weeks. The AUC for trisomy 21 was 0.999 for cfDNA testing and 0.958 for standard screening (P=0.001). Trisomy 21 was detected in 38 of 38 women (100%; 95% confidence interval [CI], 90.7 to 100) in the cfDNA-testing group, as compared with 30 of 38 women (78.9%; 95% CI, 62.7 to 90.4) in the standard-screening group (P=0.008). False positive rates were 0.06% (95% CI, 0.03 to 0.11) in the cfDNA group and 5.4% (95% CI, 5.1 to 5.8) in the standard-screening group (P<0.001). The positive predictive value for cfDNA testing was 80.9% (95% CI, 66.7 to 90.9), as compared with 3.4% (95% CI, 2.3 to 4.8) for standard screening (P<0.001). CONCLUSIONS: In this large, routine prenatal-screening population, cfDNA testing for trisomy 21 had higher sensitivity, a lower false positive rate, and higher positive predictive value than did standard screening with the measurement of nuchal translucency and biochemical analytes.

Determining the rate of elective deliveries before 39 weeks of gestation: methodology matters.

Abundant evidence suggests that neonates delivered during the early-term period (before 39 weeks of gestation) have a small but significantly increased risk of morbidity. In an effort to reduce preventable adverse outcomes, there has been growing momentum aimed at eliminating elective deliveries before 39 weeks of gestation. One of the strategies to accomplish the goal is public reporting of institutional rates. Several organizations and institutions have developed measures to report early elective delivery rates. Methodology used to derive currently reported rates varies considerably. There are differences in how an elective compared with an indicated delivery is defined. There are also differences in the denominator used to calculate the rate, ranging from all of an institution's deliveries to a subset of deliveries occurring between 37 0/7 and 38 6/7 weeks of gestation. The former denominator will give a much smaller rate than the latter despite both having the same number of elective early-term deliveries. These variations make comparison of reported rates all but impossible. In this commentary, we describe several of the currently used methodologies and their effect on reported rates to make a case for standardization. It is our opinion that the Joint Commission methodology using a large list of International Classification of Diseases, 9th Revision codes to define indications for acceptable early-term deliveries and a defined subset of 37- and 38-week deliveries for the denominator combined with a requirement for validation of the reported data is the best method available at this time.

Delayed umbilical cord clamping in premature neonates.

OBJECTIVE: Delayed umbilical cord clamping is reported to increase neonatal blood volume. We estimated the clinical outcomes in premature neonates who had delayed umbilical cord clamping compared with a similar group who had early umbilical cord clamping. METHODS: This was a before-after investigation comparing early umbilical cord clamping with delayed umbilical cord clamping (45 seconds) in two groups of singleton neonates, very low birth weight (VLBW) (401-1,500 g) and low birth weight (LBW) (greater than 1,500 g but less than 35 weeks gestation). Neonates were excluded from delayed umbilical cord clamping if they needed immediate major resuscitation. Primary outcomes were provision of delivery room resuscitation, hematocrit, red cell transfusions, and the principle Vermont Oxford Network outcomes. RESULTS: In VLBW neonates (77 delayed umbilical cord clamping, birth weight [mean±standard deviation] 1,099±266 g; 77 early umbilical cord clamping 1,058±289 g), delayed umbilical cord clamping was associated with less delivery room resuscitation, higher Apgar scores at 1 minute, and higher hematocrit. Delayed umbilical cord clamping was not associated with significant differences in the overall transfusion rate, peak bilirubin, any of the principle Vermont Oxford Network outcomes, or mortality. In LBW neonates (172 delayed umbilical cord clamping, birth weight [mean±standard deviation] 2,159±384 g; 172 early umbilical cord clamping 2,203±447 g), delayed umbilical cord clamping was associated with higher hematocrit and was not associated with a change in delivery room resuscitation or Apgar scores or with changes in the transfusion rate or peak bilirubin. Regression analysis showed increasing gestational age and birth weight and delayed umbilical cord clamping were the best predictors of higher hematocrit and less delivery room resuscitation. CONCLUSION: Delayed umbilical cord clamping can safely be performed in singleton premature neonates and is associated with a higher hematocrit, less delivery room resuscitation, and no significant changes in neonatal morbidities. LEVEL OF EVIDENCE: II.

Non-Invasive Chromosomal Evaluation (NICE) Study: results of a multicenter prospective cohort study for detection of fetal trisomy 21 and trisomy 18.

OBJECTIVE: We sought to evaluate performance of a noninvasive prenatal test for fetal trisomy 21 (T21) and trisomy 18 (T18). STUDY DESIGN: A multicenter cohort study was performed whereby cell-free DNA from maternal plasma was analyzed. Chromosome-selective sequencing on chromosomes 21 and 18 was performed with reporting of an aneuploidy risk (High Risk or Low Risk) for each subject. RESULTS: Of the 81 T21 cases, all were classified as High Risk for T21 and there was 1 false-positive result among the 2888 normal cases, for a sensitivity of 100% (95% confidence interval [CI], 95.5-100%) and a false-positive rate of 0.03% (95% CI, 0.002-0.20%). Of the 38 T18 cases, 37 were classified as High Risk and there were 2 false-positive results among the 2888 normal cases, for a sensitivity of 97.4% (95% CI, 86.5-99.9%) and a false-positive rate of 0.07% (95% CI, 0.02-0.25%). CONCLUSION: Chromosome-selective sequencing of cell-free DNA and application of an individualized risk algorithm is effective in the detection of fetal T21 and T18.

Rectovaginal Staphylococcus aureus colonization: is it a neonatal threat?

We sought to determine the rate of Staphylococcus aureus rectovaginal colonization and positive newborn blood cultures. Routinely obtained group B streptococcus (GBS) rectovaginal specimens were cultured for S. aureus using standard microbiology procedures. S. aureus- and GBS-positive blood cultures in infants less than 3 days old were determined from our microbiology database. Overall, 1488 rectovaginal cultures were obtained. Rates of positive GBS, S. aureus, and methicillin-resistant S. aureus (MRSA) cultures were 20.2%, 8.2%, and 1.7%, respectively. Cultures were positive for methicillin-susceptible S. aureus (MSSA) and GBS or MRSA and GBS in 1.6% and 0.3% of women, respectively. There was no association between GBS and MSSA or MRSA. From 1998 to 2008, there were four positive S. aureus blood cultures (0.4/10,000 live births). The rate of early onset GBS-positive blood cultures was 2.8/10,000 live births. S. aureus rectovaginal colonization at 35 to 37 weeks is relatively uncommon and currently does not appear to pose a significant risk of early onset neonatal sepsis.

Caring for the pregnant woman presenting at periviable gestation: acknowledging the ambiguity and uncertainty.

Counseling the periviable pregnant woman presenting at the edge of viability can often be confusing for the patient and frustrating for the clinician. Although neonatal survival rates have improved dramatically over the last few decades, severe morbidity is still common. This is further complicated by the fact that the information provided to the parents regarding the outcomes may not be up to date or completely accurate. The counseling is also frequently influenced by personal beliefs and biases of the medical staff. An evidence-based approach may improve the experience for both the expectant parents and the health care team.

Counseling pregnant women who may deliver extremely premature infants: medical care guidelines, family choices, and neonatal outcomes.

OBJECTIVES: The justification of neonatal intensive care for extremely premature infants is contentious and of considerable importance. The goal of this report is to describe our experience implementing consensus medical staff guidelines used for counseling pregnant women threatening extremely premature birth between 22 and 26 weeks' postmenstrual age and to give an account of family preferences and the immediate outcome of their infants. METHODS: Retrospective chart review was performed for all women threatening premature birth between 22 and 26 weeks postmenstrual age who presented to our high-risk obstetric service between June 2003 and December 2006. Women participated in comprehensive periviability counseling, which featured our specific obstetric and neonatology care recommendations for them and their infant at each gestational week. A subset of women were approached to obtain consent for a 2-step interview process beginning 3 days after the initial periviability counseling and followed with a 6- to 18-month assessment. RESULTS: Two hundred sixty women were identified as eligible subjects. After periviability counseling, but before any birth, palliative comfort care was requested by a higher percentage of families at each decreasing week. Ninety-five of the 260 women delivered 121 infants at <27 weeks' postmenstrual age. At delivery, at the request of the families and with the agreement of the medical staff, the following proportions of these infants were provided palliative comfort care: 100% at 22 weeks, 61% at 23 weeks, 38% at 24 weeks, 17% at 25 weeks, and 0% at 26 weeks. All nonresuscitations and comfort care measures were supported by the medical and nursing staffs, and all infant deaths occurred within 171 minutes. Fifty women consented to a postcounseling interview, and 25 of them also participated in a follow-up interview 6 to 18 months later. The counseling process and the guidelines were viewed as highly understandable, useful, consistent, and done in a comfortable manner. The tone and content of the parental comments regarding the counseling process were very positive, even more so at the later interview. There were no complaints or negative comments regarding the counseling process or the infant outcomes. CONCLUSIONS: Rational, consensus periviability guidelines are well accepted and can be used by all neonatologists, obstetricians, and nurses who provide care to pregnant women and infants at extremely early gestational ages. Pregnant women see these guidelines as highly understandable, useful, consistent, and respectful. When encouraged to participate with attending staff in discussions involving morbidity and mortality outcomes of premature infants and consensus medical practice recommendations, a substantial proportion of parents will choose palliative comfort care for their extremely premature infant up through 25 weeks' postmenstrual age. We believe the choice of neonatal intensive care versus palliative comfort care in extremely premature infants rightfully belongs to medically informed parents. More research is needed to examine how these decisions are made under diverse conditions of culture, religion, and technology.

Early goal directed therapy for sepsis during pregnancy.

Sepsis is a leading cause of death in pregnancy and results in significant perinatal mortality. These deaths occur despite the younger age of pregnant patients, the low rate of comorbid conditions and the potential for effective interventions that should result in rapid resolution of illness. To date, no "evidence-based" recommendations are specific to the pregnant patient who is critically ill or septic. Optimal care for the septic patient requires a multidisciplinary team with expertise in obstetrics, maternal-fetal medicine, critical care, infectious disease, anesthesia, and pharmacy. Coordination of care and good communication amongst team members is essential. Incorporation of early goal directed therapy for suspected sepsis into obstetric practice is needed to optimize maternal and neonatal outcomes.
