Abstract
BACKGROUND Neuraxial analgesia provides effective pain relief during labor. However, it is unclear whether neuraxial analgesia prevalence differs across U.S. hospitals. The aim of this study was to assess hospital variation in neuraxial analgesia prevalence in California. METHODS A retrospective cross-sectional study analyzed birthing patients who underwent labor in 200 California hospitals from 2016 to 2020. The primary exposure was the delivery hospital. The outcomes were hospital neuraxial analgesia prevalence and between-hospital variability, before and after adjustment for patient and hospital factors. Median odds ratio and intraclass correlation coefficients quantified between-hospital variability. The median odds ratio estimated the odds of a patient receiving neuraxial analgesia when moving between hospitals. The intraclass correlation coefficients quantified the proportion of the total variance in neuraxial analgesia use due to variation between hospitals. RESULTS Among 1,510,750 patients who underwent labor, 1,040,483 (68.9%) received neuraxial analgesia. Both unadjusted and adjusted hospital prevalence exhibited a skewed distribution characterized by a long left tail. The unadjusted and adjusted prevalences were 5.4% and 6.0% at the 1st percentile, 21.0% and 21.2% at the 5th percentile, 70.6% and 70.7% at the 50th percentile, 75.8% and 76.6% at the 95th percentile, and 75.9% and 78.6% at the 99th percentile, respectively. The adjusted median odds ratio (2.3; 95% CI, 2.1 to 2.5) indicated substantially increased odds of a patient receiving neuraxial analgesia if they moved from a hospital with a lower odds of neuraxial analgesia to one with higher odds. The hospital explained only a moderate portion of the overall variability in neuraxial analgesia (intraclass correlation coefficient, 19.1%; 95% CI, 18.8 to 20.5%). CONCLUSIONS A long left tail in the distribution and wide variation exist in the neuraxial analgesia prevalence across California hospitals that is not explained by patient and hospital factors. Addressing the low prevalence among hospitals in the left tail requires exploration of the interplay between patient preferences, staffing availability, and care providers' attitudes toward neuraxial analgesia.

Abstract
OBJECTIVE Data from the academic medical centers in the United States showing improvements in survival of periviable infants born at 22 to 24 weeks GA may not be nationally representative since a substantial proportion of preterm infants are cared for in community hospital-based neonatal intensive care units. Our objective was to examine the national trends in survival and other short-term outcomes among preterm infants born at ≤24 weeks gestational age (GA) in the United States from 2009 to 2018. STUDY DESIGN This was a retrospective, repeated cross-sectional analysis of the National Inpatient Sample for preterm infants ≤24 weeks GA. The primary outcome was the trends in survival to discharge. Secondary outcomes were the trends in the composite outcome of death or one or more major morbidity (bronchopulmonary dysplasia, necrotizing enterocolitis stage ≥2, periventricular leukomalacia, severe intraventricular hemorrhage, and severe retinopathy of prematurity). The Cochran-Armitage trend test was used for trend analysis. p-Value <0.05 was considered significant. RESULTS Among 71,854 infants born at ≤24 weeks GA, 34,251 (47.6%) survived less than 1 day and were excluded. Almost 93% of those who survived <1 day were of ≤23 weeks GA. Among the 37,603 infants included in the study cohort, 48.1% were born at 24 weeks GA. Survival to discharge at GA ≤ 23 weeks increased from 29.6% in 2009 to 41.7% in 2018 (p < 0.001), while survival to discharge at GA 24 weeks increased from 58.3 to 65.9% (p < 0.001). There was a significant decline in the secondary outcomes among all the periviable infants who survived ≥1 day of life. CONCLUSION Survival to discharge among preterm infants ≤24 weeks GA significantly increased, while death or major morbidities significantly decreased from 2009 to 2018. The postdischarge survival, health care resource use, and long neurodevelopmental outcomes of these infants need further investigation. KEY POINTS · Survival increased significantly in infants ≤24 weeks GA in the United States from 2009 to 2018.. · Death or major morbidity in infants ≤24 weeks GA decreased significantly from 2009 to 2018.. · Death or surgical procedures including tracheostomy, VP shunt placement, and PDA surgical closure in infants <=24 weeks GA decreased significantly from 2009 to 2018..

Patient‐Centered
Care Culture. Health Serv Res 2022; 57:806-819. [PMID: 35128641 PMCID: PMC9264452 DOI: 10.1111/1475-6773.13949] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2021] [Revised: 01/14/2022] [Accepted: 01/18/2022] [Indexed: 11/04/2022] Open
Abstract
OBJECTIVE To develop and test a measure of patient-centered care (PCC) culture in hospital-based perinatal care. DATA SOURCES Data were obtained from US perinatal hospitals: one provided survey development data and 14 contributed data for survey testing. STUDY DESIGN We used qualitative and quantitative methods to develop the mother-infant centered care (MICC) culture survey. Qualitative methods included observation, focus group, interviews, and expert consultations to adapt items from other settings and create new items capturing dimensions of PCC articulated by The Commonwealth Fund. We quantitatively assessed survey psychometric properties using reliability (Cronbach's α and Pearson correlation coefficients) and validity (exploratory and confirmatory factor analysis [CFA]) statistics, and refined the survey. After confirming aggregation suitability (ICCs), we calculated "MICC culture scores" at the individual, unit, and hospital level and assessed associations between scores and survey-collected, staff-reported outcomes to evaluate concurrent validity. DATA COLLECTION Survey development included 12 site-visit observations, one semi-structured focus group (five participants), two semi-structured interviews, five cognitive interviews, and three expert consultations. Survey testing used online surveys administered to obstetric and neonatal unit staff (N = 316). PRINCIPAL FINDINGS Using responses from 10 hospitals with ≥4 responses from both units (n = 240), the 20-item MICC culture survey demonstrated reliability (Cronbach's α = 0.95) while capturing all PCC dimensions (subscale Cronbach's α = 0.72-0.87). CFA showed validity through goodness-of-fit (overall chi-square = 214 [p-value = 0.012], SRMR = 0.056, RMSEA = 0.041, CFI = 0.97, and TLI = 0.96). Aggregation statistics (ICCs < 0.05) justify unit- and hospital-level aggregation. Demonstrating preliminary validity, individual-, unit-, and hospital-level MICC culture scores were associated with all outcomes (satisfaction with care provided, within-unit team effectiveness, and relational coordination [RC] between units) (p-values < 0.05), except for neonatal unit scores and RC (p-value = 0.11). CONCLUSIONS The MICC culture survey is a psychometrically sound measure of PCC culture for hospital-based perinatal care. Survey scores are associated with staff-reported outcomes. Future studies with patient outcomes will aid identification of improvement opportunities in perinatal care.

Abstract
OBJECTIVE To describe the status of implementation of the Alliance for Innovation in Maternal Health's primary cesarean birth patient safety bundle in Maryland after 1 year (2016-2017), and assess whether hospital characteristics and implementation strategies employed are associated with bundle implementation. METHODS The Alliance for Innovation in Maternal Health's bundle to decrease primary cesarean births includes 26 evidence-based practices that hospitals can adopt based on specific needs. One year after the start of a statewide implementation collaborative at 31 of 32 birthing hospitals in Maryland, we sent a computer-based survey to hospital collaborative leaders to assess progress. Respondents reported on hospital characteristics, adoption of bundle practices, and use of 15 selected implementation strategies. We conducted descriptive and bivariate analyses of their responses. RESULTS Among 26 hospitals with complete reporting, 23 fully implemented at least one bundle practice (range 1-7) during the collaborative's first year. Of 26 bundle practices, on average, hospitals had fully implemented a third (mean 8.6; SD 5.5; range 0-17) before the collaborative, and 3 new practices (SD 2.4; range 0-8) during the collaborative. Hospitals' use of six implementation strategies, all highly dependent on strong clinician involvement, was significantly associated with their fully implementing more practices during the collaborative's first year. CONCLUSION Our assessment has promising results, with a majority of hospitals having implemented new cesarean birth bundle practices during the collaborative's first year. However, there are lessons from the wide variability in the number and type of practices adopted. Clinicians should be aware of this variability and become more involved in the implementation of cesarean birth bundle practices. We identified six strategies associated with full implementation of more bundle practices for which clinicians' support and commitment to practice changes are critical. Clinicians' understanding of available and effective implementation strategies can better assist with the implementation of this and other Alliance for Innovation in Maternal Health patient safety bundles.

Abstract
Environmental conditions and resources that may influence provider's behaviors have been investigated in birth environments focusing on location rather than conditions and available resources. Using a descriptive, cross sectional design, we surveyed a random sample of certified nurse-midwives (CNMs), obstetricians, family practice physicians, and certified professional midwives (CPMs) to describe conditions, resources, and workforce present during U.S. births. In all, 1,243 midwives and physicians reported most environmental resources were present at almost 100% of births they attended. Conditions varied: room noise acceptability restriction of phone calls/texts from any source and lighting kept to a minimum. Trainees were present at most births regardless of setting and provider type. The impact of room noise, phone calls/texting, and lighting on outcomes should be determined. The roles and impact of personnel, including trainees, should be described. The extent to which clusters of resources are associated with outcomes might provide new directions for interventions that improve care.

Abstract
OBJECTIVE To assess hospital practices in obstetric quality management activities and identify institutional characteristics associated with utilization of evidence-supported practices. METHODS Data for this study came from a statewide survey of obstetric hospitals in California regarding their organization and delivery of perinatal care. We analyzed responses from 185 hospitals that completed quality assurance sections of the survey to assess their practices in a broad spectrum of quality enhancement activities. The association between institutional characteristics and adoption of evidence-supported practices (ie, those supported by prior literature or recommended by professional organizations as beneficial for improving birth outcome or patient safety) was examined using bivariate analysis and appropriate statistical tests. RESULTS Most hospitals regularly audited adherence to written protocols regarding critical areas of care; however, 77.7% and 16.8% reported not having written guidelines on diagnosis of labor arrest and management of abnormal fetal heart rate, respectively. Private nonprofit hospitals were more likely to have a written protocol for management of abnormal fetal heart rate (P=.002). One in 10 hospitals (9.7%) did not regularly review cases with significant morbidity or mortality, and only 69.0% regularly tracked indications for cesarean delivery. Moreover, 26.3%, 14.3%, and 8.7% of the hospitals reported never performing interprofessional simulations for eclampsia, shoulder dystocia, or postpartum hemorrhage, respectively. Teaching status was associated with more frequent simulations in these three areas (P≤.04 for all), while larger volume was associated with more frequent simulations for eclampsia (P=.04). CONCLUSION Hospitals in California engage in a wide range of practices to assure or improve quality of obstetric care, but substantial variation in practice exists among hospitals. There is opportunity for improvement in adoption of evidence-supported practices.

Abstract
Significant racial/ethnic disparities in maternal morbidity and mortality exist in the United States. Black women are 3-4 times more likely to die a pregnancy-related death as compared with white women. Growing research suggests that hospital quality may be a critical lever for improving outcomes and narrowing disparities. This overview reviews the evidence demonstrating that hospital quality is related to maternal mortality and morbidity, discusses the pathways through which these associations between quality and severe maternal morbidity generate disparities, and concludes with a discussion of possible levers for action to reduce disparities by improving hospital quality.

Abstract
This special article presents potentially important trends and issues affecting the field of obstetric anesthesia drawn from publications in 2015. Both maternal mortality and morbidity in the United States have increased in recent years because, in part, of the changing demographics of the childbearing population. Pregnant women are older and have more pre-existing conditions and complex medical histories. Cardiovascular and noncardiovascular medical diseases now account for half of maternal deaths in the United States. Several national and international organizations have developed initiatives promoting optimal obstetric and anesthetic care, including guidelines on the obstetric airway, obstetric cardiac arrest protocols, and obstetric hemorrhage bundles. To deal with the increasing burden of high-risk parturients, the national obstetric organizations have proposed a risk-based classification of delivery centers, termed as Levels of Maternal Care. The goal of this initiative is to funnel more complex obstetric patients toward high-acuity centers where they can receive more effective care. Despite the increasing obstetric complexity, anesthesia-related adverse events and morbidity are decreasing, possibly reflecting an ongoing focus on safe systems of anesthetic care. It is critical that the practice of obstetric anesthesia expand beyond the mere provision of safe analgesia and anesthesia to lead in developing and promoting comprehensive safety systems for obstetrics and team-based coordinated care.

Abstract
Background Health care improvement efforts should be aligned in order to make a meaningful impact on health systems. Appropriate care delivery could be a unifying goal to help coordinate efforts to improve health outcomes and ensure system sustainability. A more complete understanding of how appropriate care is currently conceived in research and clinical practice could help inform a more integrated and holistic concept of appropriate care that could guide health care policy and delivery practices. We examined the current understanding of appropriate care by identifying its use and definitions in recently published literature. Methods An integrated review of the practices, goals and perspectives of appropriate care in English language peer-reviewed articles published from 2011 to 2016. Inductive content analysis was used to describe emerging themes of appropriate care in articles meeting inclusion criteria. Results This integrative review included empirical studies, reviews, and commentaries with various health care settings, cultural contexts, and perspectives. Conceptualizations of appropriate care varied, however most descriptions fell into five main categories: evidence-based care, clinical expertise, patient-centeredness, resource use, and equity. These categories were often used in combination, indicating an integrated understanding of appropriate care. Conclusions An understanding of how appropriate care is conceptualized in research and policy can help inform an integrated approach to appropriate care delivery in policy and practice according to the relevant priorities and circumstances.

Abstract
Objective To evaluate whether busy days on a labour and delivery unit are associated with maternal and neonatal complications of childbirth in California hospitals, accounting for weekday/weekend births. Design This is a population-based retrospective cohort study. Setting Linked vital statistics/patient discharge data for California births between 2009 and 2010 from the Office of Statewide Health Planning and Development. Participants All singleton, cephalic, non-anomalous California births between 2009 and 2010 (N=724 967). Main outcomes The key exposure was high daily obstetric volume, defined as giving birth on a day when the number of births exceeded the hospital-specific 75th percentile of daily delivery volume. Outcomes were a range of maternal and neonatal complications. Results Several maternal and neonatal complications were increased on high-volume days and weekends following adjustment for maternal demographics, annual hospital birth volume and teaching hospital status. For example, compared with low-volume weekdays, the odds of Apgar <7 on low-volume weekend days and high-volume weekend days were 11% (adjusted OR (aOR) 1.11, CI 1.03 to 1.21) and 29% higher (aOR 1.29, CI 1.10 to 1.52), respectively. High volume was associated with increased odds of neonatal seizures on weekdays (aOR 1.33, CI 1.01 to 1.71) and haemorrhage on weekends (aOR 1.11, CI 1.01 to 1.22). After accounting for between-hospital variation, weekend delivery remained significantly associated with increased odds of Apgar score <7, neonatal intensive care unit admission, prolonged maternal length of stay and the odds of neonatal seizures remained increased on high-volume weekdays. Conclusions Our findings suggest that weekend delivery is a consistent risk factor for a range of perinatal complications and there may be variability in how well hospitals handle surges in volume.
