Risk of Severe Maternal Morbidity in Birthing People With Opioid Use Disorder.

INTRODUCTION: We examined severe maternal morbidity (SMM) among birthing people with opioid use disorder (OUD) and evaluated the extent to which differences in SMM exist by race and ethnicity. METHODS: We performed a retrospective cohort study using hospital discharge data for all Massachusetts births between 2016 and 2020. SMM rates for all SMM indicators, except transfusions, were computed for those diagnosed with and without OUD. Multivariable logistic regression was used to examine the association between OUD and SMM after adjusting for patient and hospital characteristics, including race and ethnicity. RESULTS: Among 324,012 childbirths, the SMM rate was 148 (95% confidence interval [CI]. 115-189) per 10,000 childbirths among birthing people with OUD compared with 88 (95% CI, 85-91) for those without. In adjusted models, both OUD and race/ethnicity were significantly associated with SMM. Birthing people with OUD had 2.12 (95% CI, 1.64-2.75) times the odds of experiencing an SMM event compared with those without. Non-Hispanic Black and Hispanic birthing people were at 1.85 (95% CI, 1.65-2.07) and 1.26 (95% CI, 1.13-1.41) higher odds of experiencing SMM compared with non-Hispanic White birthing people. Among birthing people with OUD, the odds of SMM were not significantly different between birthing people of color and non-Hispanic White individuals. CONCLUSIONS: Birthing people with OUD are at an elevated risk of SMM, underscoring the need for improved access to OUD treatment and increased support. Perinatal quality improvement collaboratives should measure SMM in bundles aimed at improving outcomes for birthing people with OUD.

Decreasing Decision-to-Incision Times for Unscheduled, Urgent Cesarean Deliveries.

OBJECTIVE: To standardize the preprocedure process for urgent, unscheduled cesarean deliveries to decrease the time from decision to skin incision to improve maternal and fetal outcomes. METHODS: In our quality-improvement project, we selected indications that require urgent cesarean deliveries, created a standard algorithm, then implemented a multidisciplinary process intended to reduce decision-to-incision time. This initiative was conducted from May 2019 to May 2021, with a preimplementation period from May 2019 to November 2019 (n=199), implementation period from December 2019 to September 2020 (n=283), and postimplementation period from October 2020 to May 2021 (n=160). An interrupted time series calculation was performed, with stratification by patient race and ethnicity. The primary process measure was mean decision-to-incision time. The secondary outcomes were neonatal status as measured by 5-minute Apgar score and quantitative blood loss during the cesarean delivery. RESULTS: We analyzed 642 urgent cesarean deliveries; 199 were preimplementation of the standard algorithm, and 160 were postimplementation. The mean decision-to-incision time improved from 88 minutes (95% CI 75-101 min) to 50 minutes (95% CI 47-53 min) from the preimplementation period to the postimplementation period. When stratified by race and ethnicity, the mean decision-to-incision time among Black non-Hispanic patients improved from 98 minutes (95% CI 73-123 min) to 50 minutes (95% CI 45-55 min) (t=3.27, P <.01); it improved from 84 minutes (95% CI 66-103 min) to 49 minutes (95% CI 44-55 min) among Hispanic patients (t=3.51, P <.001). There was no significant improvement in decision-to-incision time among patients in other racial and ethnic groups. When the cesarean delivery was performed for fetal indications, Apgar scores were significantly higher in the postimplementation period compared with the preimplementation period (8.5 vs 8.8 beta=0.29, P <.01). CONCLUSION: Development and implementation of a standard algorithm to expedite decision-to-incision time for unscheduled, urgent cesarean deliveries led to a significant decrease in decision-to-incision time.

Development and testing of a decision aid to achieve shared decision-making for routine labor induction.

BACKGROUND: This quality improvement project aimed to create a decision aid for labor induction in healthy pregnancies at or beyond 39 weeks that met the needs of pregnant people least likely to experience shared decision-making and to identify and test implementation strategies to support its use in prenatal care. METHODS: We used quality improvement and qualitative methods to develop, test, and refine a patient decision aid. The decision aid was tested in three languages by providers across obstetrics, family medicine, and midwifery practices at a tertiary care hospital and two community health centers. Outcomes included patients' understanding of their choices, pros and cons of choices, and the decision being theirs or a shared one with their provider. RESULTS: Patient interview data indicated that shared decision-making on labor induction was achieved. Across three Plan-Do-Study-Act cycles, we interviewed a diverse group of 24 pregnant people: 20 were people of color, 16 were publicly insured, and 15 were born outside the United States. All but one (23/24) reported feeling the decision was theirs or a shared one with their provider. The majority could name induction choices they had along with pros and cons. Interviewees described the decision-making experience as empowering and positive. Nine medical providers tested the decision aid and gave feedback. Providers stated the tool helped improve the quality of their counseling and reduce bias. CONCLUSION: This project suggests that using an evidence-based and well-tested decision aid can help achieve shared decision-making on labor induction for a diverse group of pregnant people.

Implementation of a pharmacological prophylaxis bundle to prevent obstetric-associated venous thromboembolism.

PURPOSE: Venous thromboembolism (VTE) accounts for a significant proportion of pregnancy-related mortality. In response to a series of VTEs at our institution and in accordance with mounting medical evidence for increased assessment, we implemented a universal, standardized obstetric VTE risk assessment process during antepartum and postpartum admissions and corresponding pharmacological thromboprophylaxis, which extends into the postdischarge period to prevent pregnancy-associated VTE in our urban, safety-net population. SUMMARY: This quality improvement (QI) project used the Institute for Healthcare Improvement's Model for Improvement. We analyzed data from chart audits, patient and pharmacy outreach, and electronic reports using statistical process control charts. A review of 407 charts showed an increase in the proportion of patients undergoing documented risk assessment from 0% to 80% (average of 61%) from July 2015 to June 2016. The average risk assessment rate increased from 61% to 98% from July 2016 through March 2021 after the screening was integrated into the electronic health record (EHR). Rate of receipt of recommended thromboprophylaxis during admission increased from an average of 85% before EHR integration to 94% after integration. The proportion of high-risk patients receiving prescriptions upon discharge increased from 7% before EHR integration to 87% after integration. We interviewed 117 patients by telephone, of whom 74% continued the medications at home. CONCLUSION: An interprofessional team can achieve high rates of obstetric inpatient VTE risk assessment, pharmacological thromboprophylaxis initiation, and outpatient continuation using QI methodology.

The association of hourly second-stage documentation with cesarean delivery and maternal blood loss.

PURPOSE OF THE ARTICLE: Cesarean rates and maternal morbidity increase with the duration of the second stage of labor. We studied the effect of hourly evaluation and documentation during the second stage of labor on maternal and fetal outcomes. MATERIALS AND METHODS: We performed a retrospective cohort study of all women who delivered at our urban, tertiary care hospital and underwent a second stage of greater than 60 min between 1 June 2016 and 31 May 2019. There were 1498 patients with complete data. Four hundred forty patients had hourly evaluation and documentation throughout the second stage and 1058 did not. We performed t-tests, Chi-squared, and regression analyses to compare cesarean delivery rate, second-stage duration, quantitative blood loss, hemorrhage and blood transfusion rates, and fetal outcomes. We performed regression analyses to evaluate for independent effect of this intervention on each outcome. RESULTS: Patients with hourly evaluation and documentation had a decreased likelihood of cesarean delivery (8.2% vs. 20.3%, p < .001), shorter second-stage of labor (98.1 min vs. 177.5 min, p < .001), decreased quantitative blood loss (514.4 mL vs. 667.7 mL, p < .001), and hemorrhage rate (12.5% vs. 19.9%, p < .001). Hourly evaluation was associated with decreased transfusion rates (3.2% vs. 5.6%, p = .05) but was not related to the number of units transfused. Regression analyses confirmed the impact of hourly documentation when potential confounders were included. These differences in outcomes were also noted when evaluation was performed and documented within every 75 min. Hourly second-stage evaluation and documentation did not affect other maternal or infant morbidities. CONCLUSION: Hourly evaluation and documentation in the second stage was associated with decreased cesarean delivery rate, second-stage duration, quantitative blood loss, hemorrhage, and transfusion.

Implementation of a Universal Screening Process for Substance Use in Pregnancy.

OBJECTIVE: To implement a standardized universal substance use screening process in an outpatient prenatal clinic at an urban tertiary care hospital. METHODS: Using a quality-improvement framework that involved process modeling, stakeholder analyses, and plan-do-study-act cycles, we implemented universal substance use screening for prenatal patients using a modified 5Ps screening tool (Parents, Peers, Partner, Past, Present). Implementation included an operational workflow based on the SBIRT (Screening, Brief Intervention, Referral to Treatment) model. The primary outcome measure was percentage of patients who were screened for substance use, with a goal of 90% screened. Secondary outcome measures were percentage who screened positive and percentage of the time a positive screen resulted in documentation of a brief intervention by a health care practitioner. RESULTS: Over a 19-month implementation period, 733 patient encounters were sampled. A substance use screen was completed in 618 (84%). We exceeded our goal of screening 90% of eligible patients for the final 6 months of data collection. Of the 618 completed screens, 124 (20%) screened positive. Health care practitioner documentation of brief interventions for patients with a positive screen reached 80% in the final phase of implementation, but then declined to 50% by the completion of the study period. CONCLUSION: A sustainable and generalizable process to carry out substance use screening within a large prenatal practice is feasible, and assisted with identification of patients not known to be at risk. Further efforts are needed to evaluate how to sustain health care practitioner documentation of intervention in response to positive screens.

Oral or Vaginal Misoprostol for Labor Induction and Cesarean Delivery Risk.

OBJECTIVE: To evaluate whether cervical ripening with oral misoprostol increases cesarean delivery risk and prolongs time to vaginal delivery compared with vaginal misoprostol in a predominantly overweight population. METHODS: This single center, retrospective cohort study was performed at a tertiary care academic medical center and compared labor induction outcomes with vaginal misoprostol to outcomes with oral misoprostol after a complete institutional shift to oral misoprostol. Labor induction using 25 micrograms vaginal misoprostol in 2013-2014 was compared with 50 micrograms oral misoprostol in 2014-2015. The primary outcome was cesarean delivery. Secondary outcomes included time to vaginal delivery, uterine tachysystole, maternal hemorrhage, and composite adverse neonatal outcomes. Demographics and outcomes were analyzed using standard statistical tests. Multivariable regression models accounting for potential confounders were created for the primary and secondary outcomes with adjusted odds ratios (aOR) as the measures of effect. RESULTS: There were 138 women in the oral and 138 women in the vaginal misoprostol groups. In the overall cohort, the median (interquartile range) body mass index was 31.7 (28.2-36.8) and most women (72%) were of either black or Hispanic race or ethnicity. The frequency of cesarean delivery was higher in the oral than the vaginal misoprostol group (32% vs 21%; P=.04). The adjusted odds of cesarean was higher with oral misoprostol (aOR 2.01; 95% CI 1.07-3.76). Among nulliparous women, the frequency of cesarean delivery was 41% in the oral and 28% in the vaginal misoprostol groups (aOR 2.79; 95% CI 1.26-6.19). Women had a longer time to vaginal delivery in the oral compared with vaginal misoprostol group (41 vs 31 hours respectively, P=.01). Tachysystole occurred more frequently with vaginal misoprostol (20% vs 11%; P=.04). CONCLUSION: Compared with vaginal misoprostol, oral misoprostol may be associated with increased risk of cesarean delivery and longer time to vaginal delivery.

The Association of Maternal Asthma and Early Pregnancy Vitamin D with Risk of Preeclampsia: An Observation From Vitamin D Antenatal Asthma Reduction Trial (VDAART).

BACKGROUND: Maternal asthma, uncontrolled asthma, and low vitamin D levels during pregnancy have been individually linked to increased risk of preeclampsia. OBJECTIVE: To investigate the association of history of physician-diagnosed asthma and uncontrolled asthma status during pregnancy with the risk of preeclampsia and the effects of early pregnancy vitamin D concentrations on this relationship. METHODS: A total of 816 subjects with available pregnancy outcome data and risk factors of interest were analyzed. A group of experienced obstetricians and gynecologists from 3 study centers validated the preeclampsia diagnoses. Vitamin D was measured using the DiaSorin method at 10 to 18 weeks of gestation. The Pregnancy-Asthma Control Test was used to assess asthma control during pregnancy. Criterion-based stepwise variable selection algorithm was applied to investigate the relationships of risk factors of interest (history of asthma diagnosis, uncontrolled asthma during pregnancy, and vitamin D) to preeclampsia. RESULTS: The incidence of preeclampsia was not related to the presence of asthma diagnosis (8.9% with vs 7.4% without). The adjusted odds of preeclampsia controlled for maternal serum 25-hydroxyvitamin D (25OHD) concentrations was higher for women with a higher proportion of uncontrolled asthma months per visit during pregnancy (adjusted odds ratio, 3.55; 95% CI, 1.15-13.0). Adjusting for asthma control status during pregnancy, an additional decrease in the associated preeclampsia risk by 7% was observed for a 10-unit (ng/mL) increase in early pregnancy 25OHD levels (adjusted odds ratio10-unit, 0.60; 95% CI, 0.43-0.82) as compared with the previous risk estimate of preeclampsia associated with low maternal 25OHD unadjusted for asthma control status. CONCLUSIONS: Uncontrolled asthma during pregnancy is associated with an increased risk of preeclampsia. Early pregnancy 25OHD contributes to the association of uncontrolled asthma status with preeclampsia.

Incidence and Predictors of Venous Thromboembolism in Abdominoplasty.

BACKGROUND: The prevention of venous thromboembolism (VTE) is a high priority in aesthetic surgery. Abdominoplasty is the aesthetic procedure most commonly associated with VTE, yet the mechanisms for the development of VTE associated with this procedure are unclear. OBJECTIVES: The purpose of this study was to analyze the incidence and predictors of VTE in patients undergoing abdominoplasty procedures in outpatient surgery centers using data from the Internet Based Quality Assurance Program (IBQAP). METHODS: IBQAP data from 2001 to 2011 were queried retrospectively to identify abdominoplasty cases and VTE cases. Patient- and procedure-specific variables were analyzed to identify potential predictors of VTE in abdominoplasty. RESULTS: Among all outpatient aesthetic surgery cases entered from 2001 to 2011, 414 resulted in VTE, representing a VTE incidence of 0.02%. Of these, 240 (58%) occurred in abdominoplasty cases. Predictors of VTE were age greater than 40 years and BMI greater than 25 kg/m2. Patient sex, duration of anesthesia and surgery, type of anesthesia, type of additional procedure, and number of procedures did not appear to influence the risk of VTE. Importantly, 95.5% of the VTEs identified for this study occurred in patients whose Caprini risk assessment model score was between 2 and 8, which would not be an indication for chemoprophylaxis according to current recommendations. CONCLUSIONS: Many factors must be considered when determining the true incidence of VTE in abdominoplasty. Research is needed to discover the reason abdominoplasty carries a greater risk compared with other aesthetic surgery procedures so that appropriate steps can be taken to prevent its occurrence and improve the safety of the procedure.

Lost opportunities to prevent early onset type 2 diabetes mellitus after a pregnancy complicated by gestational diabetes.

OBJECTIVES: Gestational diabetes mellitus (GDM) greatly increases the risk of developing diabetes in the decade after delivery, but few women receive appropriately timed postpartum glucose testing (PPGT) or a referral to primary care (PC) for continued monitoring. This qualitative study was designed to identify barriers and facilitators to testing and referral from patient and providers' perspectives. METHODS: We interviewed patients and clinicians in depth about knowledge, values, priorities, challenges, and recommendations for increasing PPGT rates and PC linkage. Interviews were coded with NVIVO data analysis software, and analyzed using an implementation science framework. RESULTS: Women reported motivation to address GDM for the health of the fetus. Most women did not anticipate future diabetes for themselves, and focused on delivery outcomes rather than future health risks. Patients sought and received reassurance from clinicians, and were unlikely to discuss early onset following GDM or preventive measures. PPGT barriers described by patients included provider not mentioning the test or setting it up, transportation difficulties, work responsibilities, fatigue, concerns about fasting while breastfeeding, and timing of the test after discharge from obstetrics, and no referral to PC for follow-up. Practitioners described limited communication among multiple care providers during pregnancy and delivery, systems issues, and separation of obstetrics from PC. CONCLUSIONS: Patients' barriers to PPGT included low motivation for self-care, structural obstacles, and competing priorities. Providers reported the need to balance risk with reassurance, and identified systems failures related to test timing, limitations of electronic medical record systems (EMR), lack of referrals to PC, and inadequate communication between specialties. Prevention of early onset has great potential for medical cost savings and improvements in quality of life.

Effect of Prenatal Supplementation With Vitamin D on Asthma or Recurrent Wheezing in Offspring by Age 3 Years: The VDAART Randomized Clinical Trial.

IMPORTANCE: Asthma and wheezing begin early in life, and prenatal vitamin D deficiency has been variably associated with these disorders in offspring. OBJECTIVE: To determine whether prenatal vitamin D (cholecalciferol) supplementation can prevent asthma or recurrent wheeze in early childhood. DESIGN, SETTING, AND PARTICIPANTS: The Vitamin D Antenatal Asthma Reduction Trial was a randomized, double-blind, placebo-controlled trial conducted in 3 centers across the United States. Enrollment began in October 2009 and completed follow-up in January 2015. Eight hundred eighty-one pregnant women between the ages of 18 and 39 years at high risk of having children with asthma were randomized at 10 to 18 weeks' gestation. Five participants were deemed ineligible shortly after randomization and were discontinued. INTERVENTIONS: Four hundred forty women were randomized to receive daily 4000 IU vitamin D plus a prenatal vitamin containing 400 IU vitamin D, and 436 women were randomized to receive a placebo plus a prenatal vitamin containing 400 IU vitamin D. MAIN OUTCOMES AND MEASURES: Coprimary outcomes of (1) parental report of physician-diagnosed asthma or recurrent wheezing through 3 years of age and (2) third trimester maternal 25-hydroxyvitamin D levels. RESULTS: Eight hundred ten infants were born in the study, and 806 were included in the analyses for the 3-year outcomes. Two hundred eighteen children developed asthma or recurrent wheeze: 98 of 405 (24.3%; 95% CI, 18.7%-28.5%) in the 4400-IU group vs 120 of 401 (30.4%, 95% CI, 25.7%-73.1%) in the 400-IU group (hazard ratio, 0.8; 95% CI, 0.6-1.0; P = .051). Of the women in the 4400-IU group whose blood levels were checked, 289 (74.9%) had 25-hydroxyvitamin D levels of 30 ng/mL or higher by the third trimester of pregnancy compared with 133 of 391 (34.0%) in the 400-IU group (difference, 40.9%; 95% CI, 34.2%-47.5%, P < .001). CONCLUSIONS AND RELEVANCE: In pregnant women at risk of having a child with asthma, supplementation with 4400 IU/d of vitamin D compared with 400 IU/d significantly increased vitamin D levels in the women. The incidence of asthma and recurrent wheezing in their children at age 3 years was lower by 6.1%, but this did not meet statistical significance; however, the study may have been underpowered. Longer follow-up of the children is ongoing to determine whether the difference is clinically important. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00920621.

Labor and Delivery Experiences of Mothers with Suspected Large Babies.

OBJECTIVE: To characterize the prevalence of and factors associated with clinicians' prenatal suspicion of a large baby; and to determine whether communicating fetal size concerns to patients was associated with labor and delivery interventions and outcomes. METHODS: We examined data from women without a prior cesarean who responded to Listening to Mothers III, a nationally representative survey of women who had given birth between July 2011 and June 2012 (n = 1960). We estimated the effect of having a suspected large baby (SLB) on the odds of six labor and delivery outcomes. RESULTS: Nearly one-third (31.2%) of women were told by their maternity care providers that their babies might be getting "quite large"; however, only 9.9% delivered a baby weighing ≥4000 g (19.7% among mothers with SLBs, 5.5% without). Women with SLBs had increased adjusted odds of medically-induced labor (AOR 1.9; 95% CI 1.4-2.6), attempted self-induced labor (AOR 1.9; 95% CI 1.4-2.7), and use of epidural analgesics (AOR 2.0; 95% CI 1.4-2.9). No differences were noted for overall cesarean rates, although women with SLBs were more likely to ask for (AOR 4.6; 95% CI 2.8-7.6) and have planned (AOR 1.8; 95% CI 1.0-4.5) cesarean deliveries. These associations were not affected by adjustment for gestational age and birthweight. CONCLUSIONS FOR PRACTICE: Only one in five US women who were told that their babies might be getting quite large actually delivered infants weighing ≥4000 g. However, the suspicion of a large baby was associated with an increase in perinatal interventions, regardless of actual fetal size.

Racial and Ethnic Differences in the Likelihood of Vaginal Birth After Cesarean Delivery.

BACKGROUND: A major contributor to the increase in cesarean deliveries over recent decades is the decline in vaginal births after cesarean (VBAC). Racial and ethnic disparities in other perinatal outcomes are widely recognized, but few studies have been directed toward racial/ethnic differences in VBAC rates. METHODS: We used the population-based Massachusetts Pregnancy to Early Life (PELL) database to investigate racial/ethnic differences in rates of VBAC for Massachusetts residents with one prior cesarean from 1998 to 2008. RESULTS: The overall VBAC rate was 17.3 percent. After adjusting for demographic, behavioral, and medical risk factors, non-Hispanic Asian mothers had a greater likelihood of VBAC than non-Hispanic white mothers (adjusted risk ratio 1.31 [95% CI 1.23-1.39]). No other racial/ethnic group was significantly different from non-Hispanic whites in adjusted analyses. The likelihood of VBAC also decreased with increasing maternal age. DISCUSSION: Non-Hispanic Asian women are significantly more likely to have VBAC than non-Hispanic white women. Efforts to reduce cesarean delivery rates in the United States should address these disparities. Future research should investigate factors underlying these differences to ensure that all women have access to appropriate maternity care services.

Deep venous thrombosis: prevention and management.

This article summarizes current information on the risk and the assessment of risks for deep venous thrombosis (DVT) resulting from plastic surgery procedures. Risk assessment is the foundation for recommended methods of prevention of DVT and, in turn, possible pulmonary emboli. If prevention fails, treatment of DVT is required to avoid the major complication of pulmonary emboli. The significant risk of DVT and pulmonary emboli after an abdominoplasty is confirmed in this article.

Evidence-based medicine and data sharing in outpatient plastic surgery.

The Authors discuss the importance of evidence based medicine (EBM) as related particularly to outpatient surgery. They discuss the five core steps in current EBM and take the reader through each of the steps, listing methods the surgeon can follow to achieve a thorough and relevant evidence based plan. Challenges of EBM such as reporting bias and evidence grading are discussed along with solutions and tools to meet those challenges. The article concludes with a look at data sharing as a means of enabling surgeons to access outcomes and specific aspects of care for a surgical procedure.

Patient safety series: obstetric safety improvement and its reflection in reserved claims.

In reviewing outcomes that are associated with the implementation of a series of labor and delivery patient safety efforts from 2004-2009, we requested data on the number of related professional liability claims that were reserved by our insurance companies that are established with the specific objective of financing risks that emanate from their parent group or groups. While we restructured the manner in which we give care, required training modules, and provided simulations to our providers, our legal risk continued to be monitored independently and in parallel. Retrospective review of the number of cases for which money was held in reserve for claims demonstrated a 20% decrease per year, which was adjusted for delivery volume, over this time period. We believe that the improved care that resulted from our safety projects has led to this decreased legal risk.
