Engaging Black sexual minority women in breast cancer research: Lessons in community partnerships.

BACKGROUND: Black sexual minority women (BSMW) face significant breast cancer health inequities and are underrepresented in health research because of historical and present-day exclusion. However, there exists no peer-reviewed literature on best practices for the inclusion of BSMW in cancer research. "Our Breast Health: The Access Project" was a national primary data collection study in June 2018 through October 2019 that aimed to identify facilitators and barriers to breast cancer care among BSMW, and that successfully recruited the highest number of BSMW for any national breast cancer screening study at the time of its publication. METHODS: The present analysis highlights best practices for reaching BSMW by examining by how effective various recruitment sources were at recruiting BSMW. Recruitment partners were grouped into several categories: (1) cancer focused, (2) Black women or sexual minority women focused, (3) BSMW focused, (4) social media, and (5) other. Then logistic regression was used to estimate the odds that a particular recruitment source category could recruit BSMW compared with other categories. RESULTS: Partnerships with community-based organizations led by and intended for BSMW were the most successful at recruiting BSMW, demonstrating the importance of an intersectional approach to recruitment. Community-based organizations focused on BSMW specifically were 26 times more successful in recruiting BSMW to the study compared with recruiting Black women who were not sexual minorities (odds ratio, 26.43 [95% CI, 7.50-93.10]). CONCLUSIONS: Successful recruitment enables breast cancer research grounded in the perspectives of BSMW, which can generate key findings that have the potential to remedy longstanding health inequities for this population.

Capacity-Building for Collecting Patient-Reported Outcomes and Experiences (PRO) Data Across Hospitals.

PURPOSE: Patient-reported outcomes and experiences (PRO) data are an integral component of health care quality measurement and PROs are now being collected by many healthcare systems. However, hospital organizational capacity-building for the collection and sharing of PROs is a complex process. We sought to identify the factors that facilitated capacity-building for PRO data collection in a nascent quality improvement learning collaborative of 16 hospitals that has the goal of improving the childbirth experience. DESCRIPTION: We used standard qualitative case study methodologies based on a conceptual framework that hypothesizes that adequate organizational incentives and capacities allow successful achievement of project milestones in a collaborative setting. The 4 project milestones considered in this study were: (1) Agreements; (2) System Design; (3) System Development and Operations; and (4) Implementation. To evaluate the success of reaching each milestone, critical incidents were logged and tracked to determine the capacities and incentives needed to resolve them. ASSESSMENT: The pace of the implementation of PRO data collection through the 4 milestones was uneven across hospitals and largely dependent on limited hospital capacities in the following 8 dimensions: (1) Incentives; (2) Leadership; (3) Policies; (4) Operating systems; (5) Information technology; (6) Legal aspects; (7) Cross-hospital collaboration; and (8) Patient engagement. From this case study, a trajectory for capacity-building in each dimension is discussed. CONCLUSION: The implementation of PRO data collection in a quality improvement learning collaborative was dependent on multiple organizational capacities for the achievement of project milestones.

The Impact of Race and Ethnicity on Use of Minimally Invasive Surgery for Myomas.

STUDY OBJECTIVE: To determine whether minimally invasive surgery (MIS) for uterine myomas is used differentially based on race and ethnicity. DESIGN: Retrospective cohort study. SETTING: Quaternary care academic hospital in the United States. PATIENTS: Patients undergoing hysterectomy or myomectomy for uterine myomas between March 15, 2015, and March 14, 2020 (N = 1311). Cases involving correction of pelvic organ prolapse, malignancy, peripartum hysterectomy, or combined procedures with nongynecologic specialties were excluded. Racial/ethnic composition of the study population was 40.0% non-Hispanic white (white), 27.9% non-Hispanic black (black), 14.0% Hispanic, 13.7% non-Hispanic Asian (Asian), and 4.3% non-Hispanic American Indian/Alaska Native/Pacific Islander/Other. INTERVENTIONS: Hysterectomy, myomectomy. MEASUREMENTS AND MAIN RESULTS: Of the 1311 cases, 35.9% were minimally invasive hysterectomy, 16.4% abdominal hysterectomy, 35.6% minimally invasive myomectomy, and 12.1% abdominal myomectomy. MIS rates were 94.7% among fellowship-trained minimally invasive gynecologic surgery subspecialists, 44.2% among obstetrics and gynecology specialists, and 46.8% among gynecologic oncologists. There were disparities in surgeon type based on race/ethnicity, with 59.8% of white patients having undergone surgery with a minimally invasive gynecologic surgery subspecialist vs 44.0% of black patients and 45.7% of Hispanic patients. Black and Hispanic patients were less likely to undergo MIS overall vs white patients (adjusted odds ratio [aOR] 0.33, 95% confidence interval [CI] 0.22-0.48 and aOR 0.44, 95% CI 0.28-0.72, respectively). Black and Hispanic patients undergoing hysterectomy were less likely than white patients to undergo MIS (aOR 0.33, 95% CI 0.21-0.51 and aOR 0.35, 95% CI 0.20-0.60, respectively). There were no significant differences in rates of MIS based on race/ethnicity for myomectomies nor differences in major or minor complications by race/ethnicity overall. CONCLUSION: At a quaternary care institution, black and Hispanic patients were significantly less likely than white patients to undergo MIS for uterine myomas, particularly for hysterectomy.

Routine Multidisciplinary Review of Severe Maternal Morbidity Is Associated with a Reduction in Preventable Cases of Severe Maternal Morbidity.

OBJECTIVE: Severe maternal morbidity (SMM) has increased by 45% in the United States and is estimated to affect up to 1.5% of all deliveries. Research has not yet been conducted that demonstrates a benefit to multidisciplinary review of SMM. The aim of our study was to determine if standardized, routine review of the cases of SMM by a multidisciplinary committee results in a reduction of potentially preventable cases of SMM. STUDY DESIGN: A retrospective cohort study of all women admitted for delivery at Cedars-Sinai Medical Center from March 1, 2012 to September 30, 2016. Our cohort was separated into two groups: a preintervention group composed of women admitted for delivery prior to the implementation of the obstetric Quality and Peer Review Committee (OBQPRC), and a postintervention group where the committee had been well established. Cases of confirmed SMM were presented to a multidisciplinary research committee, and the committee determined whether opportunities for improvement in care existed. The groups were compared with determine if there was a decreased incidence of preventable SMM following the implementation of the OBQPRC standardized review process. RESULTS: There were 30,319 deliveries during the study period; 13,120 deliveries in the preintervention group; and 13,350 deliveries in the postintervention group (2,649 deliveries during the transition period). There was no difference in the rate of SMM between the preintervention (125; 0.95%) and postintervention (129; 0.97%) groups, (p = 0.91). There was a significantly lower rate of opportunity for the improvement in care in the postintervention group (29.5%) compared with the preintervention group (46%; p = 0.005). CONCLUSION: We demonstrated a significant reduction in the rate of potentially preventable SMM following the implementation of routine review of all SMM suggesting that this process plays an important role in improving maternal care and outcomes. KEY POINTS: · Benefit to routine review of SMM has not been demonstrated.. · Routine review of SMM is associated with 36% reduction in potentially preventable SMM.. · This is the first study to demonstrate the benefit of routine review of SMM..

Comparing Methods of Identifying Outlying Nurses in Audits of Low-Risk Cesarean Delivery Rates.

BACKGROUND: The low-risk cesarean delivery (CD) rate is an established performance indicator for providers in maternity care for quality improvement purposes. PURPOSE: Our objectives were to assess nurse performance using adjusted nurse-level CD rates and to compare methods of identifying nurse outliers. METHODS: We conducted a retrospective, cohort study of 6970 births attended by 181 registered nurses in one hospital's maternity unit. Adjusted and unadjusted nurse-level CD rates were compared and agreement between 3 definitions (statistical, top decile, over a benchmark) of outliers calculated. RESULTS: Adjusted nurse-level CD rates varied from 5.5% to 53.2%, and the unadjusted rates varied from 5% to 50%. Risk adjustment had little impact on the ranking of nurses, and outliers were consistently identified by 3 definitions. CONCLUSIONS: Trade-offs between statistical certainty and feasibility need to be considered when classifying nurse outliers. Findings can help target interventions to improve nurse performance.

"This is some mess right here": Exploring interactions between Black sexual minority women and health care providers for breast cancer screening and care.

BACKGROUND: Few studies have explored how the intersection of race and sexual identity contribute to breast cancer disparities for Black sexual minority women (SMW). Issues within patient-provider relationships, including bias, contribute to health disparities for minority groups. The authors used constructs from self-determination theory (SDT) to explore the nature of health care provider interactions in breast cancer screening and care among Black SMW. METHODS: Participants were sampled nationally through social media, targeted emails, and referrals. Qualitative, in-depth interviews were conducted with 15 Black cisgender SMW, ages 38 to 64 years, who had a breast cancer diagnosis or recent abnormal mammogram. Interviews were conducted face-to-face or online, audio-recorded, and transcribed verbatim. Two analysts coded the interviews. Codes were analyzed across interviews to identify themes salient to SDT. RESULTS: Themes aligned with the SDT constructs of relatedness and autonomy. Some participants discussed feeling most understood by Black and/or female providers who shared at least 1 of their identities. Feeling understood through shared identity contributed to participants feeling seen and heard by their providers. Participants who discussed negative experiences with providers believed that the provider made negative assumptions about them based on their race and/or sexual orientation. CONCLUSIONS: When interacting with health care providers for breast cancer screening and care, Black SMW face specific challenges related to their multiply marginalized social position. Reducing health care provider bias toward Black SMW may improve patients' desires to continue in care. Providing equitable care while acknowledging and respecting women with multiply marginalized identities may improve the nature of these interactions.

Delays in breast cancer care by race and sexual orientation: Results from a national survey with diverse women in the United States.

BACKGROUND: Despite known differences in breast cancer by both race and sexual orientation, data on the intersectional experiences of Black sexual minority women (BSMW) along the care continuum are scant. This study sought to understand delays in breast cancer care by examining the intersection of race and sexual orientation. METHODS: This online, cross-sectional survey enrolled racially and sexually diverse women aged ≥ 35 years who had been diagnosed with breast cancer within the prior 10 years or had an abnormal screening in the prior 24 months. The authors calculated summary statistics by race/sexual orientation categories, and they conducted univariate and multivariable modeling by using multiple imputation for missing data. RESULTS: BSMW (n = 101) had the highest prevalence of care delays with 5.17-fold increased odds of a care delay in comparison with White heterosexual women (n = 298) in multivariable models. BSMW reported higher intersectional stigma and lower social support than all other groups. In models adjusted for race, sexual orientation, and income, intersectional stigma was associated with a 2.43-fold increase in care delays, and social support was associated with a 32% decrease in the odds of a care delay. CONCLUSIONS: Intersectional stigma may be an important driver of breast cancer inequities for BSMW. Reducing stigma and ensuring access to appropriate social support that addresses known barriers can be an important approach to reducing inequities in the breast cancer care continuum.

Beyond Black and White: race and sexual identity as contributors to healthcare system distrust after breast cancer screening among US women.

OBJECTIVE: Healthcare system distrust (HCSD) has been linked to poor breast cancer outcomes. Previous HSCD analyses have focused on Black-White disparities; however, focusing only on race ignores the complex set of factors that form identity. We quantified the contributions of race and sexual minority (SM) identity to HCSD among US women who had received breast cancer screening. METHODS: This cross-sectional study used intersectionality decomposition methods to assess the degree to which racial and SM identity contributed to disparate responses to the validated 9-item HCSD Scale. The sample included online survey participants identifying as a Black or White woman living in the US, with a self-reported abnormal breast cancer screening result in the past 24 months and/or breast cancer diagnosis since 2011. RESULTS: Of 649 participants, 49.4% of Black SM women (n = 85) were in the highest HCSD tertile, followed by 37.4% of White SM women (n = 123), 24.4% of Black heterosexual women (n = 156), and 19% of White heterosexual women. Controlling for age, 72% of the disparity in HCSD between Black SM women and White heterosexual women was due to SM status, 23% was due to racial identity, and 3% was due to both racial and SM identity. CONCLUSIONS: SM identity emerged as the largest driver of HCSD disparities; however, the combined racial and SM disparity persisted. Excluding sexual identity in HCSD studies may miss an important contributor. Interventions designed to increase the HCS's trustworthiness at the provider and system levels should address both racism and homophobia.

Alcohol testing and alcohol involvement among violent deaths by state, 2014-2016.

Blood alcohol concentration (BAC) testing rates vary across states, potentially biasing estimates of alcohol involvement in violent deaths. The National Violent Death Reporting System (NVDRS) collects information on violent deaths, including decedents' BACs. This study assessed characteristics of violent deaths by BAC testing status, and the proportion of decedents with a positive BAC or BAC ≥ 0.08 g/dL. NVDRS data from 2014 to 2016 (2014: 18 states; 2015: 27 states; 2016: 32 states) were analyzed to assess BAC testing (tested, not tested, unknown/missing) by state, decedent characteristics, and death investigation system (e.g., state medical examiner, coroners), in 2019. The proportion of violent deaths with a BAC > 0.0 or ≥ 0.08 g/dL was also assessed. Among 95,390 violent death decedents, 57.1% had a BAC test (range: 9.5% in Georgia to 95.8% in Utah), 2.3% were not tested, and 40.6% had an unknown/missing BAC testing status (range: 1.3% in Alaska to 78.0% in Georgia). Decedents who were 21-44 years, American Indian/Alaska Native or Hispanic, died by poisoning, died by undetermined intent, or were investigated by a state medical examiner were most likely to receive BAC testing. Among the violent deaths with a reported BAC, 41.1% had a positive BAC and 27.7% had a BAC ≥ 0.08 g/dL. About 2 in 5 violent deaths were missing data on alcohol testing. Increased testing and reporting of alcohol among violent deaths could inform the development and use of evidence-based prevention strategies (e.g., increasing alcohol taxes, regulating alcohol outlet density) for reducing violent deaths.

Postoperative Urinary Retention after Benign Gynecologic Surgery with a Liberal versus Strict Voiding Protocol.

STUDY OBJECTIVE: Surgeons employ various methods for evaluating what is considered a common occurrence after gynecologic operations, postoperative urinary retention (POUR). Few have reported the incidence of POUR with a liberal voiding protocol (no requirement to void before discharge). The primary objective of this study was to evaluate the risk of POUR after benign gynecologic surgery, comparing a liberal voiding protocol with more strict voiding protocols. Secondary outcomes included length of hospital stay (LOS) and urinary tract infection (UTI). DESIGN: Retrospective cohort study. SETTING: Quaternary-care academic hospital in the United States. PATIENTS: Patients undergoing hysterectomy or myomectomy at Cedars-Sinai Medical Center from August 2017 through July 2018 (n = 652). Cases involving incontinence operations, correction of pelvic organ prolapse, malignancy, or peripartum hysterectomy were excluded. INTERVENTIONS: Hysterectomy, myomectomy. MEASUREMENTS AND MAIN RESULTS: POUR, defined as the need for recatheterization within 24 hours of catheter removal, along with UTI and LOS were compared between liberal and strict voiding protocols. A subgroup analysis was performed for those undergoing minimally invasive surgery (MIS). A total of 303 (46.5%) women underwent surgery with a liberal postoperative voiding protocol and 349 (53.5%) women with a strict voiding protocol. Overall, the incidence of POUR was low at 3.8% and not different between the groups (2.6% liberal vs. 4.9% strict, p = .14). UTIs also occurred infrequently (2.8% overall, 2.6% liberal vs. 2.9% strict, p = .86). Similar results were seen specifically among those who underwent MIS: POUR (3.7% overall, 2.8% liberal vs. 5.3% strict, p = .17) and UTI (3.3% overall, 2.4% liberal vs. 4.7% strict, p = .28). The median LOS (interquartile range) was much shorter for MIS patients with a liberal voiding protocol (median 15 hours overall [interquartile range 15 hours], 9 [4] hours liberal vs. 36 [34] hours strict, p <.01). Among those discharged the same day (72.6% of the MIS cases), patients with a liberal voiding protocol had a significantly shorter LOS than those with strict (mean [standard deviation] 9.4 [2.5] hours vs. 10.6 [35] hours, p <.01). Postoperative complications occurred less frequently in those with MIS procedures (11.8% in MIS vs. 20.2% in laparotomies, p <.01) and those with liberal voiding protocols (11.2% liberal vs. 16.9% strict p = .04). CONCLUSION: Overall, POUR occurs infrequently after major benign gynecologic surgery and does not differ between those with liberal and strict voiding protocols. Our data suggest that same-day discharge after MIS hysterectomy and myomectomy without a requirement to void does not increase the risk of POUR and shortens LOS. Eliminating voiding protocols after these procedures may facilitate greater efficiency in the postanesthesia recovery unit and may contribute to enhanced recovery after surgery protocols.

Risk of Urinary Tract Infection Symptoms after Posthysterectomy Cystoscopy with 50% Dextrose as Compared with Saline Cystoscopy with Indigo Carmine.

STUDY OBJECTIVE: Compare odds of postoperative urinary symptoms in women who had cystoscopy after benign laparoscopic hysterectomy with 50% dextrose and with normal saline solution with intravenous indigo carmine. DESIGN: Retrospective cohort study. SETTING: Two tertiary care centers. PATIENTS: All women who underwent benign laparoscopic hysterectomy and intraoperative cystoscopy carried out by a single surgeon. INTERVENTIONS: We compared postoperative urinary symptoms in patients who received 50% dextrose cystoscopy fluid (January 2016-June 2017) with those who received saline cystoscopy with intravenous indigo carmine (November 2013-April 2014). MEASUREMENTS AND MAIN RESULTS: A total of 96 patients had cystoscopy with 50% dextrose and 104 with normal saline with intravenous indigo carmine. Differences in baseline characteristics of the two groups of participants mainly reflected institutional population diversity: age (45.2 vs 41.9, p = .01), body mass index (26.9 vs 33.4, p <.01), race, current smoking status (1% vs 7.8%, p = .04), diabetes (2.1% vs 11.5%, p = .01), history of abdominal surgery (53.1% vs 74%, p <.01), hysterectomy type, receipt of intraoperative antibiotics (92.7% vs 100%, p <.01), recatheterization (10.4% vs 0%, p <.01), and removal of catheter on postoperative day 0 (66.7% vs 12.5%, p <.01). Urinary symptoms were similar for 50% dextrose and saline (12.5% vs 7.7%, p = .19). After adjusting for age, body mass index, race, diabetes, and day of catheter removal, there remained no significant differences in urinary symptoms between the groups (odds ratio 3.19 [95% confidence interval, 0.82-12.35], p = .09). One immediate bladder injury was detected in the saline group and 1 delayed lower urinary tract injury in the 50% dextrose group. CONCLUSION: Overall, most women experienced no urinary symptoms after benign laparoscopic hysterectomy. There were no significant differences in postoperative urinary symptoms or empiric treatment of urinary tract infection after the use of 50% dextrose cystoscopy fluid as compared with normal saline. The previous finding of increased odds of urinary tract infection after dextrose cystoscopy may be due to use in a high-risk population.

Variability in antemortem and postmortem blood alcohol concentration levels among fatally injured adults.

Background: Excessive alcohol use is a risk factor for injury-related deaths. Postmortem blood samples are commonly used to approximate antemortem blood alcohol concentration (BAC) levels.Objectives: To assess differences between antemortem and postmortem BACs among fatally injured adults admitted to one shock trauma center (STC).Method: Fifty-two adult decedents (45 male, 7 female) admitted to a STC in Baltimore, Maryland during 2006-2016 were included. STC records were matched with records from Maryland's Office of the Chief Medical Examiner (OCME). The antemortem and postmortem BAC distributions were compared. After stratifying by antemortem BACs <0.10 versus ≥0.10 g/dL, differences in postmortem and antemortem BACs were plotted as a function of length of hospital stay.Results: Among the 52 decedents, 22 died from transportation-related injuries, 20 died by homicide or intentional assault, and 10 died from other injuries. The median BAC antemortem was 0.10 g/dL and postmortem was 0.06 g/dL. Thirty-one (59.6%) decedents had antemortem BACs ≥0.08 g/dL versus 22 (42.3%) decedents using postmortem BACs. Postmortem BACs were lower than the antemortem BACs for 42 decedents, by an average of 0.07 g/dL. Postmortem BACs were higher than the antemortem BACs for 10 decedents, by an average of 0.06 g/dL.Conclusion: Postmortem BACs were generally lower than antemortem BACs for the fatally injured decedents in this study, though not consistently. More routine antemortem BAC testing, when possible, would improve the surveillance of alcohol involvement in injuries. The findings emphasize the usefulness of routine testing and recording of BACs in acute care facilities.

Patient Discharge without an Order to Void in the Outpatient Gynecologic Surgery Setting.

STUDY OBJECTIVE: To evaluate if there is a difference in hospital readmission when patients are required to void versus not required to void before discharge after a same-day gynecologic procedure. DESIGN: A retrospective cohort study. SETTING: An urban tertiary care hospital. PATIENTS: A total of 4743 patients undergoing same-day gynecologic surgery. INTERVENTIONS: The readmission rates of patients discharged home without an order to void were compared with those with an order to void. Chart review was performed for readmission within 30 days and time to discharge from the postanesthesia recovery unit. MEASUREMENTS AND MAIN RESULTS: There was no statistically significant difference in the readmission rate between patients with or without an order to void before discharge (0.4% vs 0.9%, p = .08). Only 3 patients were readmitted for urinary retention, all with an order to void before discharge. Compared with gynecologic surgeons treating benign conditions, gynecologic oncologists were 23% more likely to place an order to void before discharge. Patients without an order to void spent approximately 59 minutes more in the postanesthesia care unit compared with those required to void (p <.01). CONCLUSION: Discharge without an order to void is a safe practice in patients undergoing same-day gynecologic procedures. The risk of postdischarge urinary retention is low, consistent with previously reported rates in the literature.

Childbirth-specific patient-reported outcomes as predictors of hospital satisfaction.

BACKGROUND: Under value-based payment programs, patient-reported experiences and outcomes can impact hospital and physician revenue. To enable obstetrical providers to improve the childbirth experience, a framework for understanding what women expect and desire during childbirth is needed. OBJECTIVE: The purpose of this study was to identify key predictors of childbirth hospital satisfaction with the use of the Childbirth Experiences Survey. STUDY DESIGN: This study builds on a larger effort that used Patient-Reported Outcomes Management Information System methods to develop a childbirth-specific preliminary patient-reported experiences and outcomes item bank. These efforts led to the development of an antepartum and postpartum survey (Childbirth Experiences Survey Parts 1 and 2). All phases of the study were conducted with the participation of a community-based research team. We conducted a prospective observational study using national survey response panels that was organized through Nielsen to identify women's antepartum values and preferences for childbirth (Childbirth Experiences Survey Part 1). Eligible participants were pregnant women in the United States (English or Spanish speaking) who were ≥18 years old and ≥20 weeks pregnant. Women were recontacted and invited to participate in a postpartum follow-up survey to collect information about their childbirth patient-reported experiences and outcomes, which included childbirth satisfaction (Childbirth Experiences Survey Part 2). In bivariate analyses, we tested whether predisposing conditions (eg, patient characteristics or previous experiences), values and preferences, patient-reported experiences and outcomes, and the "gaps" between values and preferences and patient-reported experiences and outcomes were predictors of women's satisfaction with hospital childbirth services. Multivariable logistic regression models were fitted to examine the simultaneous effect of predictors on hospital satisfaction, which were adjusted for key predisposing conditions. RESULTS: From 500 women who anticipated a vaginal delivery at the time of the antepartum survey, who labored before delivery, and who answered the postpartum survey, key findings included the following responses: (1) the strongest predictors of women's satisfaction with hospital childbirth services were items in the domains of staff communication, compassion, empathy, and respect, and (2) 23 childbirth-specific patient-reported experiences and outcomes were identified. Examples of these patient-reported experiences and outcomes (such as being told about progress in labor and being involved in decisions regarding labor pain management) appeared especially relevant to women who experienced childbirth. A final model that predicted women's satisfaction with hospital childbirth services included a total of 8 items that could be optimized by doctors, midwives, and hospitals. These included the patient's report of how well she coped with labor pain, whether the hospital provided adequate space and food for their support person, and whether she received practical support for feeding the newborn infant. CONCLUSION: This study identified 23 childbirth-specific patient-reported experiences and outcomes that were predictors of childbirth hospital satisfaction. The implementation of the Childbirth Experiences Survey Parts 1 and 2 in a multihospital setting may lead to the development of childbirth hospital performance measures and strategies for improvement of the childbirth experience.

Antibiotics during Intrauterine Balloon Tamponade Is Associated with a Reduction in Endometritis.

OBJECTIVE: To evaluate whether prophylactic antibiotics at the time of placement of an intrauterine balloon tamponade (IBT) is associated with a reduction in postpartum endometritis. STUDY DESIGN: Retrospective cohort study of patients who received an IBT from January 1, 2012, to December 12, 2016. Patients were included if the IBT remained in place at least 2 hours and excluded if chorioamnionitis was present. Patients who received prophylactic antibiotics at the time of IBT placement were compared with those who did not. RESULTS: A total of 149 subjects received an IBT; 36 were excluded due to early removal or chorioamnionitis. Of the remaining, 59 received prophylactic antibiotics and 54 did not. Baseline characteristics were similar between the groups except mode of delivery. The majority (65%) of those who did not receive prophylactic antibiotics had a cesarean delivery (p = 0.03). The overall incidence of endometritis was 15%. The incidence of endometritis was greater among those patients who did not receive prophylactic antibiotics compared with those who did (5 vs. 26%; p < 0.002; odds ratio [OR]: 6.53; 95% confidence interval [CI]: 1.76-24.25). This association remained after adjustment for mode of delivery and receiving group B Streptococcus antibiotics prior to delivery (adjusted OR: 5.9; 95% CI: 1.58-22.35). CONCLUSION: Prophylactic antibiotics were associated with a reduction in postpartum endometritis among patients receiving an IBT.

Gene-Environment Interaction in Parkinson's Disease: Coffee, ADORA2A, and CYP1A2.

BACKGROUND AND PURPOSE: Drinking caffeinated coffee has been reported to provide protection against Parkinson's disease (PD). Caffeine is an adenosine A2A receptor (encoded by the gene ADORA2A) antagonist that increases dopaminergic neurotransmission and Cytochrome P450 1A2 (gene: CYP1A2) metabolizes caffeine; thus, gene polymorphisms in ADORA2A and CYP1A2 may influence the effect coffee consumption has on PD risk. METHODS: In a population-based case-control study (PASIDA) in Denmark (1,556 PD patients and 1,606 birth year- and gender-matched controls), we assessed interactions between lifetime coffee consumption and 3 polymorphisms in ADORA2A and CYP1A2 for all subjects, and incident and prevalent PD cases separately using logistic regression models. We also conducted a meta-analysis combining our results with those from previous studies. RESULTS: We estimated statistically significant interactions for ADORA2A rs5760423 and heavy vs. light coffee consumption in incident (OR interaction = 0.66 [95% CI 0.46-0.94], p = 0.02) but not prevalent PD. We did not observe interactions for CYP1A2 rs762551 and rs2472304 in incident or prevalent PD. In meta-analyses, PD associations with daily coffee consumption were strongest among carriers of variant alleles in both ADORA2A and CYP1A2. CONCLUSION: We corroborated results from a previous report that described interactions between ADORA2A and CYP1A2 polymorphisms and coffee consumption. Our results also suggest that survivor bias may affect results of studies that enroll prevalent PD cases.

Confirmed severe maternal morbidity is associated with high rate of preterm delivery.

BACKGROUND: Because severe maternal morbidity (SMM) is increasing in the United States, affecting up to 50,000 women per year, there was a recent call to review all mothers with SMM to better understand their morbidity and improve outcomes. Administrative screening methods for SMM have recently been shown to have low positive predictive value for true SMM after chart review. To ultimately reduce maternal morbidity and mortality we must better understand risk factors, and preventability issues about true SMM such that interventions could be designed to improve care. OBJECTIVE: Our objective was to determine risk factors associated with true SMM identified from California delivery admissions, including the relationship between SMM and preterm delivery. STUDY DESIGN: In this retrospective cohort study, SMM cases were screened for using International Classification of Diseases, Ninth Revision codes for severe illness and procedures, prolonged postpartum length of stay, intensive care unit admission, and transfusion from all deliveries in 16 hospitals from July 2012 through June 2013. Charts of screen-positive cases were reviewed and true SMM diagnosed based on expert panel agreement. Underlying disease diagnosis was determined. Women with true-positive SMM were compared to SMM-negative women for the following variables: maternal age, ethnicity, gestational age at delivery, prior cesarean delivery, and multiple gestation. RESULTS: In all, 491 women had true SMM and 66,977 women did not have SMM for a 0.7% rate of true SMM. Compared to SMM-negative women, SMM cases were significantly more likely to be age >35 years (33.6 vs 23.8%; P < .0001), be African American (14.1 vs 7.9%; P < .0001), have had a multiple gestation (9.7 vs 2.1%; P < .0001), and, for the multiparous women, have had a prior cesarean delivery (58 vs 30.2%; P < .0001). Preterm delivery was significantly more common in SMM women compared to SMM-negative women (41 vs 8%; P < .0001), including delivery <32 weeks (18 vs 2%; P < .0001). The most common underlying disease was obstetric hemorrhage (42%) followed by hypertensive disorders (20%) and placental hemorrhage (14%). Only 1.6% of women with SMM had cardiovascular disease as the underlying disease category. CONCLUSION: An extremely high proportion of women with severe morbidity (42.5%) delivered preterm with 17.8% delivering <32 weeks, which underscores the importance of access to appropriate-level care for mothers with SMM and their newborns. Further, the extremely high rate of preterm delivery (75%) in women with placental hemorrhage in combination with their 63% prior cesarean delivery rate highlights another risk of prior cesarean delivery: subsequent preterm delivery. These data provide a reminder that a cesarean delivery could be a contributing factor to not only hemorrhage-related SMM, but also to increased subsequent preterm delivery, more reason to continue national efforts to safely reduce initial cesarean deliveries.

Severe maternal morbidity in a large cohort of women with acute severe intrapartum hypertension.

BACKGROUND: Hypertensive diseases of pregnancy are associated with severe maternal morbidity and remain common causes of maternal death. Recently, national guidelines have become available to aid in recognition and management of hypertension in pregnancy to reduce morbidity and mortality. The increased morbidity related to hypertensive disorders of pregnancy is presumed to be associated with the development of severe hypertension. However, there are few data on specific treatment or severe maternal morbidity in women with acute severe intrapartum hypertension as opposed to severe preeclampsia. OBJECTIVE: The study aimed to characterize maternal morbidity associated with women with acute severe intrapartum hypertension, and to determine whether there was an association between various first-line antihypertensive agents and posttreatment blood pressure. STUDY DESIGN: This retrospective cohort study of women delivering between July 2012 and August 2014 at 15 hospitals participating in the California Maternal Quality Care Collaborative compared women with severe intrapartum hypertension (systolic blood pressure >160 mm Hg or diastolic blood pressure >105 mm Hg) to women without severe hypertension. Hospital Patient Discharge Data and State of California Birth Certificate Data were used. Severe maternal morbidity using the Centers for Disease Control and Prevention criteria based on International Classification of Diseases-9 codes was compared between groups. The efficacy of different antihypertensive medications in meeting the 1-hour posttreatment goal was determined. Statistical methods included distribution appropriate univariate analyses and multivariate logistic regression. RESULTS: There were 2252 women with acute severe intrapartum hypertension and 93,650 women without severe hypertension. Severe maternal morbidity was significantly more frequent in the women with severe hypertension (8.8%) compared to the control women (2.3%) (P < .0001). Severe maternal morbidity rates did not increase with increasing severity of blood pressures (P = .90 for systolic and .42 for diastolic). There was no difference in severe maternal morbidity between women treated (8.6%) and women not treated (9.5%) (P = .56). Antihypertensive treatment rates were significantly higher in hospitals with a level IV neonatal intensive care unit (85.8%) compared to a level III neonatal intensive care unit (80.2%) (P < .001), and in higher-volume hospitals (84.5%) compared to lower-volume hospitals (69.1%) (P < .001). Severe maternal morbidity rates among severely hypertensive women were significantly higher in hospitals with level III neonatal intensive care unit level compared to hospitals with a level IV neonatal intensive care unit (10.6% vs 5.7%, respectively; P < .001), and significantly higher in low-delivery volume hospitals compared to high-delivery volume hospitals (15.5% vs 7.6%, respectively; P < .001). Only 53% of women treated with oral labetalol as first-line medication met the posttreatment goal of nonsevere hypertension, significantly less than those treated with intravenous hydralazine, intravenous labetalol, or oral nifedipine (68%, 71%, and 82%, respectively) (P = .001). Severe intrapartum hypertension remained untreated in 17% of women. CONCLUSION: Women with acute severe intrapartum hypertension had a significantly higher risk of severe maternal morbidity compared to women without severe hypertension. Significantly lower antihypertensive treatment rates and higher severe maternal morbidity rates were seen in lower-delivery volume hospitals.

Opportunities for improvement in care among women with severe maternal morbidity.

BACKGROUND: Severe maternal morbidity is increasing in the United States and has been estimated to occur in up to 1.3% of all deliveries. A standardized, multidisciplinary approach has been recommended to identify and review cases of severe maternal morbidity to identify opportunities for improvement in maternal care. OBJECTIVE: The aims of our study were to apply newly described gold standard guidelines to identify true severe maternal morbidity and to utilize a recently recommended multidisciplinary approach to determine the incidence of and characterize opportunities for improvement in care. STUDY DESIGN: We conducted a retrospective cohort study of all women admitted for delivery at Cedars-Sinai Medical Center from Jan. 1, 2012, through June 30, 2014. Electronic medical records were screened for severe maternal morbidity using the following criteria: International Classification of Diseases, Ninth Revision codes for severe illness identified by the Centers for Disease Control and Prevention; prolonged length of stay; intensive care unit admission; transfusion of ≥4 U of packed red blood cells; or hospital readmission within 30 days of discharge. A multidisciplinary team conducted in-depth review of each medical record that screened positive for severe maternal morbidity to determine if true severe maternal morbidity occurred. Each true case of severe maternal morbidity was presented to a multidisciplinary committee to determine a consensus opinion about the morbidity and if opportunities for improvement in care existed. Opportunity for improvement was described as strong, possible, or none. The incidence of opportunity for improvement was determined and categorized as system, provider, and/or patient. Morbidity was classified by primary cause, organ system, and underlying medical condition. RESULTS: There were 16,323 deliveries of which 386 (2%) screened positive for severe maternal morbidity. Following review of each case, true severe maternal morbidity was present in 150 (0.9%) deliveries. We determined by multidisciplinary committee review that there was opportunity for improvement in care in 66 (44%) cases. The 2 most common underlying causes of severe maternal morbidity were hemorrhage (71.3%) and preeclampsia/eclampsia (10.7%). In cases with opportunity for improvement in care, provider factors were present in 78.8%, followed by patient (28.8%) and system (13.6%) factors. CONCLUSION: We demonstrated the feasibility of a recently recommended review process of severe maternal morbidity at a large, academic medical center. We demonstrated that opportunity for improvement in care exists in 44% of cases and that the majority of these cases had contributing provider factors.

Measuring severe maternal morbidity: validation of potential measures.

BACKGROUND: Both maternal mortality rate and severe maternal morbidity rate have risen significantly in the United Sates. Recently, the Centers for Disease Control and Prevention introduced International Classification of Diseases, 9th revision, criteria for defining severe maternal morbidity with the use of administrative data sources; however, those criteria have not been validated with the use of chart reviews. OBJECTIVE: The primary aim of the current study was to validate the Centers for Disease Control and Prevention International Classification of Diseases, 9th revision, criteria for the identification of severe maternal morbidity. This analysis initially required the development of a reproducible set of clinical conditions that were judged to be consistent with severe maternal morbidity to be used as the clinical gold standard for validation. Alternative criteria for severe maternal morbidity were also examined. STUDY DESIGN: The 67,468 deliveries that occurred during a 12-month period from 16 participating California hospitals were screened initially for severe maternal morbidity with the presence of any of 4 criteria: (1) Centers for Disease Control and Prevention International Classification of Diseases, 9th revision, diagnosis and procedure codes; (2) prolonged postpartum length of stay (>3 standard deviations beyond the mean length of stay for the California population); (3) any maternal intensive care unit admissions (with the use of hospital billing sources); and (4) the administration of any blood product (with the use of transfusion service data). Complete medical records for all screen-positive cases were examined to determine whether they satisfied the criteria for the clinical gold standard (determined by 4 rounds of a modified Delphi technique). Descriptive and statistical analyses that included area under the receiver operating characteristic curve and C-statistic were performed. RESULTS: The Centers for Disease Control and Prevention International Classification of Diseases, 9th revision, criteria had a reasonably high sensitivity of 0.77 and a positive predictive value of 0.44 with a C-statistic of 0.87. The most important source of false-positive cases were mothers whose only criterion was 1-2 units of blood products. The Centers for Disease Control and Prevention International Classification of Diseases, 9th revision, criteria screen rate ranged from 0.51-2.45% among hospitals. True positive severe maternal morbidity ranged from 0.05-1.13%. When hospitals were grouped by their neonatal intensive care unit level of care, severe maternal morbidity rates were statistically lower at facilities with lower level neonatal intensive care units (P < .0001). CONCLUSION: The Centers for Disease Control and Prevention International Classification of Diseases, 9th revision, criteria can serve as a reasonable administrative metric for measuring severe maternal morbidity at population levels. Caution should be used with the use of these criteria for individual hospitals, because case-mix effects appear to be strong.
