A Standardized Approach for Category II Fetal Heart Rate with Significant Decelerations: Maternal and Neonatal Outcomes.

OBJECTIVE: To determine if a standardized intervention process for Category II fetal heart rates (FHRs) with significant decels (SigDecels) would improve neonatal outcome and to determine the impact on mode of delivery rates. STUDY DESIGN: Patients with Category II FHRs from six hospitals were prospectively managed using a standardized approach based on the presence of recurrent SigDecels. Maternal and neonatal outcomes were compared between pre- (6 months) and post-(11 months) implementation. Neonatal outcomes were: 5-minute APGAR scores of <7, <5, <3, and severe unexpected newborn complications (UNC). Maternal outcomes included primary cesarean and operative vaginal birth rates of eligible deliveries. RESULTS: Post implementation there were 8,515 eligible deliveries, 3,799 (44.6%) were screened, and 361 (9.5%) met criteria for recurrent SigDecels. Compliance with the algorithm was 97.8%. The algorithm recommended delivery in 68.0% of cases. Relative to pre-implementation, 5-minute APGAR score of <7 were reduced by 24.6% (p < 0.05) and severe UNC by -26.6%, p = < .05. The rate of primary cesarean decreased (19.8 vs 18.3%, p < 0.05), while there were nonsignificant increases in vaginal (74.6 vs 75.8%, p = 0.13) and operative vaginal births (5.7 vs 5.9%, p = 0.6). CONCLUSION: Standardized management of recurrent SigDecels reduced the rate of 5-minute APGAR scores of < 7 and severe UNC.

A Comparison of the Nulliparous-Term-Singleton-Vertex and Society of Maternal-Fetal Medicine Cesarean Birth Metrics Based on Hospital Size.

OBJECTIVE: The purpose of this study was to compare the nulliparous-term-singleton-vertex (NTSV) and the Society of Maternal-Fetal Medicine (SMFM) cesarean birth metrics as tools for quality improvement efforts based on hospital size. MATERIALS AND METHODS: Cesarean birth rates from 275 hospitals from six states were used to evaluate the NTSV metric and 81 hospitals from four states for the SMFM metric. Data were assessed based on delivery volume, their use as an effective tool for ongoing quality improvement programs, and their ability to serve as performance-based payline indicators. RESULTS: The average NTSV and SMFM cesarean birth rates were 25.6 and 13.0%, respectively. The number of deliveries included in the NTSV metric was stable across all hospital sizes (33.1-36.2%). With the SMFM metric, there was a progressive decline in the number of deliveries included, 90.0 versus 69.6%, in relatively small to large facilities. Variability was less and precision increased with the SMFM metric, which reduced the number of hospitals that could be incorrectly categorized when using performance-based predefined cesarean birth rate paylines. CONCLUSION: The SMFM metric appears to be better suited as a tool for rapid process improvement programs aimed at reducing cesarean birth rates in low-risk patients.

Early standardized treatment of critical blood pressure elevations is associated with a reduction in eclampsia and severe maternal morbidity.

BACKGROUND: Hypertensive disorders of pregnancy result in significant maternal morbidity and mortality. State and national guidelines have been proposed to increase treatment of patients with hypertensive emergencies or critically elevated blood pressures. There are limited data available to assess the impact of these recommendations on maternal morbidity. OBJECTIVE: The purpose of this prospective quality improvement project was to determine if maternal morbidity would be improved using a standardized approach for treatment of critically elevated blood pressures. STUDY DESIGN: In all, 23 hospitals participated in this project. Treatment recommendations included the use of an intravenous blood pressure medication and magnesium sulfate when there was a sustained blood pressure of ≥160 mm Hg systolic and/or ≥110 mm Hg diastolic. Compliance with the metric recommendations was monitored based on the number of patients treated with an intravenous blood pressure medication, use of magnesium sulfate, and if they received a timely postpartum follow-up appointment. The metric was scored as all or none; missing any of the 3 metric components was considered noncompliant. From January through June 2015 baseline data were collected and hospitals were made aware that ongoing monitoring of compliance would begin in July 2015 through June 2016. The primary outcomes were composite metric compliance, the incidence of eclampsia per 1000 births, and severe maternal morbidity. RESULTS: During the 18 months of this study there were 69,449 births. Within this population, 2034 met criteria for a critically elevated blood pressure, preeclampsia, or superimposed preeclampsia with severe features. Of this group, 1520 had a sustained critical blood elevation. Initial compliance with treatment recommendations was low (50.5%) and increased to >90% after April 2016 (P < .001). Compliance with utilization of intravenous blood pressure medication increased by 33.2%, from a baseline of 57.1-90.3% (P < .01) during the last 6 months of monitoring. Compliance with utilization of magnesium sulfate increased by 10.8%, from a baseline of 85.4-96.2% (P < .01). The incidence of eclampsia declined by 42.6% (1.15 ± 0.15/1000 to 0.62 ± 0.09/1000 births). Severe maternal morbidity decreased by 16.7% from 2.4 ± 0.10% to 2.0 ± 0.15% (P < .01). CONCLUSION: We noted 3 important findings: (1) compliance with state and national treatment guidelines is low without monitoring; (2) high levels of compliance can be achieved in a relatively short period of time; and (3) early intervention with intravenous blood pressure medication and magnesium sulfate for verified sustained critical maternal blood pressures resulted in a significant reduction in the rate of eclampsia and severe maternal morbidity. The reduction in the rate of eclampsia could only partially be attributed to the increase in the use of magnesium sulfate, suggesting an additive or synergistic effect of the combined treatment of an antihypertensive medication and magnesium sulfate on the rate of eclampsia and severe maternal morbidity.

Use of Maternal Early Warning Trigger tool reduces maternal morbidity.

BACKGROUND: Maternal mortality in the United States has increased unabated for the past 20 years. Maternal morbidity is also affecting an increasingly large number of women in the United States. A number of national and state organizations have recommend the use of maternal early warning tools as a method to combat this problem. There are limited data suggesting that the use of these types of clinical assessment tools can reduce maternal morbidity. OBJECTIVE: We sought to determine if maternal morbidity could be reduced with the implementation of a clinical pathway-specific Maternal Early Warning Trigger (MEWT) tool. STUDY DESIGN: The tool was developed internally and prospectively implemented as a pilot project in 6 of 29 hospitals within a large hospital system. The primary goal was early assessment and treatment of patients suspected of clinical deterioration. The tool addressed the 4 most common areas of maternal morbidity: sepsis, cardiopulmonary dysfunction, preeclampsia-hypertension, and hemorrhage. To be considered positive, triggers needed to be sustained for >20 minutes and were defined as severe (single abnormal value): maternal heart rate (HR) >130 beats/min (bpm), respiratory rate >30/min, mean arterial pressure <55 mm Hg, oxygen saturation <90%, or nurse concern; or nonsevere (required 2 abnormal values): temperature >38 or <36°C, blood pressure >160/110 or <85/45 mm Hg, HR >110 or <50 bpm, respiratory rate >24 or <10/min, oxygen saturation <93%, fetal HR >160 bpm, altered mental status, or disproportionate pain. Within each group, recommended management or assessment was also provided. Outcome measures were Centers for Disease Control and Prevention (CDC)-defined severe maternal morbidity, composite maternal morbidity, and intensive care unit (ICU) admissions. Two time intervals were used to analyze the effect of the MEWT tool: a 24-month baseline control period and a 13-month MEWT study period. To determine that the findings noted were not simply changes that would have occurred without the utilization of the early warning tool, we also compared a control population from nonpilot sites during the same baseline and 13-month time periods. RESULTS: There were 36,832 deliveries at the pilot sites (24,221 pre- and 12,611 post-MEWT testing) and 146,359 at the nonpilot sites (95,718 pre- and 50,641 post-MEWT testing) during the 2 study time periods. Use of the MEWT tool resulted in significant reductions in CDC severe maternal morbidity (P < 0.01) and composite morbidity (P < 0.01). ICU admissions were unchanged. At nonpilot sites CDC severe maternal morbidity, composite morbidity, and ICU admissions were unchanged between baseline and the post-MEWT testing time period. CONCLUSION: The use of the MEWT tool in this study, designed to address 4 of the most common causes of maternal morbidity, as well as provide assessment and management recommendations, resulted in significant improvement in maternal morbidity. The variation in hospital delivery services at the pilot sites suggests that this maternal early warning tool would be suitable for use in the majority of maternity centers in the United States.

Comprehensive maternal hemorrhage protocols reduce the use of blood products and improve patient safety.

The purpose of this study was to assess the effectiveness of instituting a comprehensive protocol for the treatment of maternal hemorrhage within a large health care system. A comprehensive maternal hemorrhage protocol was initiated within a health care system with 29 different delivery units and with >60,000 annual births. Compliance with key elements of the protocol was assessed monthly by a dedicated perinatal safety nurse at each site and validated during site visits by system perinatal nurse specialist. Outcome variables were the total number of units of blood transfused and the number of puerperal hysterectomies. Three time points were assessed: (1) 2 months before implementation of the protocol, (2) a 2-month period that was measured at 5 months after implementation of the protocol, and (3) a 2-month period at 10 months after implementation. There were 32,059 deliveries during the 3 study periods. Relative to baseline, there was a significant reduction in blood product use per 1000 births (-25.9%; P < .01) and a nonsignificant reduction (-14.8%; P = .2) in the number of patients who required puerperal hysterectomy. Within a large health care system, the application of a standardized method to address maternal hemorrhage significantly reduced maternal morbidity, based on the need for maternal transfusion and peripartum hysterectomy. These data support implementation of standardized methods for postpartum care and treatment of maternal hemorrhage and support that this approach will reduce maternal morbidity.

Decreased rates of shoulder dystocia and brachial plexus injury via an evidence-based practice bundle.

OBJECTIVE: To evaluate whether a standardized approach to identify pregnant women at risk for shoulder dystocia (SD) is associated with reduced incidence of SD and brachial plexus injury (BPI). METHODS: Between 2011 and 2015, prospective data were collected from 29 community-based hospitals in the USA during implementation of an evidence-based practice bundle, including an admission risk assessment, required "timeout" before operative vaginal delivery (OVD), and low-fidelity SD drills. All women with singleton vertex pregnancies admitted for vaginal delivery were included. Rates of SD, BPI, OVD, and cesarean delivery were compared between a baseline period (January 2011-September 2013) and an intervention period (October 2013-June 2015), during which there was a system-wide average bundle compliance of 90%. RESULTS: There was a significant reduction in the incidence of SD (17.6%; P=0.028), BPI (28.6%; P=0.018), and OVD (18.0%; P<0.001) after implementation of the evidence-based practice bundle. There was a nonsignificant reduction in primary (P=0.823) and total (P=0.396) cesarean rates, but no association between SD drills and incidence of BPI. CONCLUSION: Implementation of a standard evidence-based practice bundle was found to be associated with a significant reduction in the incidence of SD and BPI. Utilization of low-fidelity drills was not associated with a reduction in BPI.

Baseline assessment of a hospital-specific early warning trigger system for reducing maternal morbidity.

OBJECTIVE: To determine whether predefined maternal early warning triggers (MEWTs) can predict pregnancy morbidity. METHODS: In a retrospective case-control study, obstetric patients admitted to the intensive care unit (ICU) between 2012 and 2013 at seven pilot US hospitals were compared with control patients who had a normal delivery outcome. Six MEWTs were assessed. RESULTS: The case and control groups each contained 50 patients. Hemorrhage (15/50, 30%), sepsis (12/50, 24%), cardiac dysfunction (8/50, 16%), and pre-eclampsia (6/50, 12%) were the most common reasons for ICU admission. Significant associations were recorded between ICU admission and tachycardia (OR 5.0, 95% CI 2.1-11.7), mean arterial pressure less than 65 mm Hg (OR 4.5, 95% CI 1.9-10.8), temperature of at least 38°C (OR 44.1, 95% CI 13.0-839.1), and altered mental state (OR 44.1, 95% CI 13.1-839.0). Two or more triggers were persistent for 30 minutes or more in 36 (72%) ICU patients versus 2 (4%) controls (OR 61.7, 95% CI 13.2-288.0). Earlier medical intervention might have led to a lesser degree of maternal morbidity for 31 (62%) ICU patients with at least one MEWT. CONCLUSION: Persistent MEWTs were present in most obstetric ICU cases. Retrospectively, MEWTs in this cohort seemed to separate normal obstetric patients from those for whom ICU admission was indicated; their use might reduce maternal morbidity.

A system-wide initiative to prevent retained vaginal sponges.

As any perinatal nurse knows, retained vaginal sponges are an obstetrical and postpartum patient safety problem. As surgical sponge counts are not routine in some obstetrical units for vaginal births, our healthcare system chose to institute a rigorous process to eliminate retained sponges in all vaginal births. This article describes this process, along with the lessons learned, when Catholic Healthcare West implemented the Sponge ACCOUNTing System in its 32 hospitals in California, Arizona, and Nevada. Implementation of this process involved the standardization of practice for obstetricians, certified nurse midwives, nurses, obstetric technicians, radiologists, and radiology technicians in the management and accounting of surgical sponges.
