The Contribution of Neighborhood Context to the Association of Race with Severe Maternal Morbidity.

OBJECTIVE: Severe maternal morbidity (SMM) has disproportionate frequencies among racial minorities and those of socioeconomic disadvantage, with people of Black race consistently having the highest proportion. Neighborhood level deprivation has been associated with maternal morbidity and mortality, including adverse pregnancy outcomes. We sought to explore the relationship between neighborhood socioeconomic disadvantage and SMM and describe how neighborhood context impacts the relationship between race and SMM. STUDY DESIGN: We performed a retrospective cohort analysis of all delivery admissions in a single health care network from 2015 to 2019. Area deprivation index (ADI) was used to represent neighborhood socioeconomic disadvantage and is a composite index of neighborhood that spans income, education, household characteristics, and housing. The index ranges from 1 to 100 with higher values indicating higher disadvantage. Logistic regression assessed the relationship between ADI and SMM and estimated the effect that ADI has on the relationship between race and SMM. RESULTS: Of the 63,208 birthing persons in our cohort, the unadjusted incidence of SMM was 2.2%. ADI was significantly associated with SMM, with higher values conferring higher risk for SMM (p < 0.001). The absolute risk of SMM increased roughly by 1.0% from the lowest to highest ADI value. Those of Black race had the highest unadjusted incidence of SMM compared with the referent group (3.4 vs. 2.0%) and highest median ADI (92; interquartile range [IQR]: 20). In the multivariable model, in which the primary exposure was race and ADI was adjusted for, Black race had a 1.7 times odds SMM when compared with White race (95% confidence interval [CI]: 1.5-1.9). This association was attenuated to 1.5 adjusted odds when controlling for ADI (95% CI: 1.3-1.7). Risk attenuation for SMM was not seen in other race categories. CONCLUSION: Neighborhood context contributes to SMM but does not explain the majority of racial disparities. KEY POINTS: · Neighborhood context is associated with SMM, with higher disadvantage conferring higher risk.. · Compared with White race, all other races had higher rates of SMM, with Black race having the highest.. · Accounting for neighborhood modestly attenuates the magnitude of association of Black race with SMM.. · Neighborhood context contributes to health outcomes but does not explain the majority of disparities..

Comparative Analysis of Obstetric Hemorrhage Risk Prediction Tools.

OBJECTIVE: Hemorrhage risk prediction tools were developed in response to rising rates of obstetric hemorrhage (OBH). The California Maternal Quality Care Collaborative (CMQCC) risk prediction tool classifies patients as low, medium, and high risk for OBH based on individual risk factors. At our institution, Magee-Womens Hospital (MWH), a unique OBH risk prediction tool was derived from the CMQCC tool that differs through its use of weighted risk factors and distinctive laboratory value cutoffs. Our objective is to compare this enhanced institution-specific tool to the CMQCC tool. STUDY DESIGN: This study was a retrospective cohort analysis of delivery admissions from a single health care network. Admission OBH risk scores were assigned to each patient using both the MWH and CMQCC scores. Cohen's kappa estimated agreement. Scoring systems and maternal outcomes were compared using chi-square test. Composite morbidity included transfusion, hysterectomy, uterine artery embolization, and intensive care unit admission. RESULTS: A total of 21,843 delivery admissions were included. A moderate association was observed between scoring systems (kappa = 0.41, p < 0.001). The CMQCC tool categorized 16,184 (74%) patients as low risk, 4,664 (21%) as medium risk, and 995 (5%) as high risk. The MWH tool categorized 13,137 (60%) patients as low risk, 8,113 (37%) as medium risk, and 593 (3%) as high risk. The MWH score recategorized CMQCC low-risk patients to a higher stratum 26% of the time. CMQCC high-risk patients were recategorized to a lower stratum 82% of the time. Both the MWH and CMQCC tools were able to differentiate OBH-related morbidity across risk strata. The MWH tool independently predicted risk of composite morbidity within each stratum of the CMQCC score. CONCLUSION: Both the MWH and CMQCC tools independently distinguish risk of composite morbidity. Adding weighted values to individual risk factors further discriminates risk of morbidity. This suggests it may be reasonable to adapt the CMQCC tool to reflect institutional populations and resources. KEY POINTS: · The nationally adopted CMQCC risk prediction tool identifies women at risk for obstetric hemorrhage.. · Our institution (MWH) developed a unique tool that weights individual risk factors to better capture risk.. · The CMQCC and MWH tools both differentiate risk; though similar to other tools, categorize a proportion of women who hemorrhage as low risk..

Implementation of a universal postpartum blood pressure monitoring program: feasibility and outcomes.

BACKGROUND: New-onset postpartum preeclampsia has a higher risk of maternal morbidity and mortality than preeclampsia with antepartum onset, underscoring the need for earlier identification of elevated blood pressure among patients with this condition. Given the decrease in healthcare engagement, which is typical of the postpartum period, new-onset postpartum hypertension often goes unrecognized. Currently, there are no recommendations for universal postpartum blood pressure surveillance in women without hypertensive disorders of pregnancy. With the shift to telemedicine because of the COVID-19 pandemic, our institution's approach was to distribute blood pressure cuffs to women receiving any portion of their prenatal care virtually, thus also providing access to an opportunity for blood pressure measurement during the postpartum period for all women. OBJECTIVE: To explore the feasibility of a patient-driven universal postpartum home blood pressure monitoring program in women without a previous diagnosis of a hypertensive disorder. STUDY DESIGN: This was a prospective observational study of all postpartum women who were discharged from our institution from July 2020 through June 2021 and who were not previously identified to have hypertension. A clinical algorithm was developed and followed. All the women received discharge educational materials and were called at a 1-week interval by a nurse to review blood pressure and preeclampsia symptoms. The maternal demographics and delivery outcomes were recorded. RESULTS: Of the 10,092 deliveries during the study period, 5959 (59%) were successfully contacted. 352 were excluded, as they did not deliver at the primary hospital; 1052 (18%) had a previous hypertensive disorder of pregnancy diagnosis; 1522 (26%) did not have a blood pressure cuff; and 1841 (31%) planned to take their blood pressure at a later time. Precautions and blood pressure parameters were given to this last group. Of the remaining 1192, 222 (19%) had an initial elevated blood pressure. Of these, 98 had a second elevated blood pressure on recheck; 17 were referred to the emergency room for evaluation, with 8 being diagnosed with severe preeclampsia; and the remainder were recommended to follow with their obstetrical provider and enrolled in our institution's remote blood pressure management program. Of the 1192 women, 8% potentially had a new diagnosis of a hypertensive disorder of pregnancy, with 0.7% having severe hypertension. Women with elevated blood pressures were more likely to be of non-Hispanic Black race and have a higher early pregnancy body mass index than those without elevated blood pressures. CONCLUSION: Our study indicates that a patient-driven postpartum blood pressure monitoring program is feasible and may be incorporated using existing resources. In addition, our findings suggest that the incidence of new-onset postpartum hypertensive disorders of pregnancy may be higher than previously assessed in retrospective cohorts. Thus, there may be a role for closer surveillance of all women with patient-driven home blood pressure monitoring, particularly those with risk factors or in the setting of limited resources.

Lessons Learned From a Gap Analysis of Obstetric Hemorrhage Protocols across a Health System.

INTRODUCTION: The United States has experienced a rising incidence of maternal deaths, including those attributable to obstetric hemorrhage (OBH). In response, the National Partnership for Maternal Safety developed a standardized OBH Consensus Bundle with the goal of universal adoption. In 2016 a large western Pennsylvania health system adopted the OBH Consensus Bundle across its 8 obstetrical units, with the goal to improve maternal outcomes. METHODS: Gap analysis was used to identify differences between existing OBH protocols and the OBH Consensus Bundle from January to June 2016. Identified gaps as well as existing practices of success were used to systematically develop and implement a standardized system-wide OBH improvement initiative. Hospitals were then categorized by annual birth volume as high (> 2000), medium (500-2000), and low (< 500) with analysis performed across these groups to identify potential trends. RESULTS: All hospitals had individual successes as well as gaps that were used to direct the system-wide OBH improvement initiative. In some cases, individual plans were tailored to meet hospital resources. When hospitals were compared by annual birth volume, variation existed in their preparedness for, and management of OBH, with the single low-volume hospital having the most gaps. DISCUSSION: This gap analysis identified areas for improvement among all hospitals in a health system regardless of annual birth volume. This systematic approach of evaluation of current protocols and identification of improvement targets with implementation strategies may improve maternity outcomes. Additionally, these lessons described may provide a useful framework for other hospitals and health systems as they implement their own safety bundles.

Isolated echogenic intracardiac foci and the role of cell-free fetal DNA: A cost-effectiveness analysis.

OBJECTIVES: Cell-free fetal DNA (cfDNA) has been increasingly incorporated into prenatal aneuploidy screening paradigms given its relatively high sensitivity for Down syndrome (DS). This is often the case when fetal ultrasonographic soft markers are present, such as the relatively common echogenic intracardiac focus (EIF). We sought to evaluate the cost-effectiveness of a screening strategy that included cfDNA screening when an isolated EIF is identified in a low-risk population with prior aneuploidy screening. METHODS: A decision-analytic model was constructed using TreeAge software with probabilities derived from the literature. Our model compared cfDNA screening following isolated EIF detection in women less than 35 years with prior reassuring first trimester screen compared to a strategy of no further aneuploidy screening. Strategies were compared to generate an incremental cost-effectiveness ratio with a threshold of $100 000/quality-adjusted life year (QALY) and applied to a theoretical cohort. RESULTS: The cfDNA strategy resulted in 21 fewer DS births and 52 additional QALYs, however, increased costs by $51.3 million. This yielded an incremental cost-effectiveness ratio of $986 503; therefore, it was not a cost-effective strategy. CONCLUSION: In a low-risk population with prior reassuring aneuploidy screening, it is not cost effective to offer cfDNA after identification of an isolated EIF.

Maternal and fetal outcomes of pancreatitis in pregnancy.

OBJECTIVE: This study examined maternal and neonatal outcomes that are associated with pancreatitis in pregnancy, in particular preeclampsia. STUDY DESIGN: We conducted a retrospective cohort study of all singleton nonanomalous pregnancies in California from 2005-2008 with an identification of all cases of pancreatitis. Outcomes of interest included preeclampsia, intrauterine fetal death, preterm delivery, and neonatal or infant death. Univariate and multivariable analyses were then conducted to examine the association of pancreatitis in pregnancy and maternal characteristics and fetal outcomes. RESULTS: Our cohort of 2,039,870 pregnant women included 342 women (0.017%) with pancreatitis. Pancreatitis in pregnancy was not associated significantly with neonatal or infant death. When assessing fetal outcomes, pancreatitis was associated with preterm delivery, small for gestational age, jaundice, respiratory distress syndrome, and intrauterine fetal death (P < .001). Of note, pregnancy-associated pancreatitis was found to be associated with preeclampsia and severe preeclampsia in both univariate (P < .001) and multivariate analysis after we controlled for potential confounders (odds ratio, 4.21 [95% confidence interval, 2.99-5.93]; odds ratio, 7.85 [95% confidence interval, 5.03-12.24], respectively). CONCLUSION: We found that pancreatitis in pregnancy was associated with several adverse maternal outcomes; in particular, a strong association existed with preeclampsia, which has its own implications and complications surrounding pregnancy management. Pancreatitis in pregnancy was also associated with increased risk for preterm delivery but not neonatal or infant death, which is consistent with the literature.

Very late complications of cervical arthroplasty: results of 2 controlled randomized prospective studies from a single investigator site.

STUDY DESIGN: Prospective, single-site, randomized, Food and Drug Administration-approved investigational device exemption clinical trials of 2 cervical arthroplasty (CA) devices. OBJECTIVE: To evaluate complications with CA occurring more than 4 years after the surgical procedure in Food and Drug Administration clinical trials of the Bryan and Prestige LP arthroplasty devices. SUMMARY OF BACKGROUND DATA: Reports of several randomized clinical studies have shown CA to be a safe and effective alternative to anterior cervical fusion in the treatment of degenerative cervical disc disorders. A majority include follow-up intervals of 4 years or less. METHODS: Between 2002 and 2006, 94 patients were enrolled in Food and Drug Administration studies of the Bryan and Prestige LP cervical disc devices. Charts, imaging studies, and hospital records were reviewed for those who underwent arthroplasty and returned more than 4 years after their surgical procedure with neck-related pain or dysfunction. RESULTS: Excluding adjacent segment disease that occurred with a similar rate for patients who underwent fusion and arthroplasty, 5 patients, all treated with arthroplasty, returned for evaluation of neck and arm symptoms between 48 and 72 months after surgery. Four patients had peridevice vertebral body bone loss. One patient had posterior device migration and presented with myelopathy. Three required revision surgery and 2 were observed. Four patients maintained follow-up and reported stabilization or improvement in symptoms. CONCLUSION: Despite their similarities, CA and fusion are not equivalent procedures in this study in regard to very late complications. Similar to large joint arthroplasty, delayed device-related complications may occur with CA. These complications commenced well beyond the time frame for complications associated with more traditional cervical spine procedures. Both patients and surgeons should be aware of the potential for very late device-related complications occurring with CA and the need for revision surgery. LEVEL OF EVIDENCE: 1.
