Labor epidural analgesia (LEA) is the most commonly administered neuraxial anesthesia for labor pain.1 In the United States, more than 70% of women receive some form of a neuraxial procedure during labor. Although the effectiveness of neuraxial anesthesia for labor pain management and the safety of neuraxial anesthesia for the fetus and newborns during the perinatal period have been well documented, the long-term effects of neuraxial anesthesia on the offspring are largely unknown.2-4 Limited toxicology and animal studies have shown that standard clinical doses of local anesthetics (LAs) can produce neurotoxic effects and alter normal behavioral development in rhesus monkeys.5 Recent observational studies with humans found that general anesthesia for cesarean deliveries was associated with an approximately 50% increased risk for children to develop autism spectrum disorders (ASDs) compared with vaginal deliveries.6,7 A recent meta-analysis comprising 61 studies with 20 million deliveries concluded that birth by cesarean delivery was significantly associated with the risk of ASD.8 However, these studies did not address the potential risk associated with the common use of neuraxial anesthesia for routine vaginal delivery. Given that LEA is currently the criterion standard for labor pain management for routine vaginal delivery, it is critical to assess whether maternal LEA exposure has any long-term association with outcomes in offspring.

Background: Postoperative mortality and complications after geriatric hip fracture surgery remain high despite efforts to improve perioperative care for these patients. One factor of particular interest is anesthetic technique, but prior studies on this are limited by sample selection, competing risks, and incomplete followup. Questions/purposes: (1) Among older patients undergoing surgery for hip fracture, does 90-day mortality differ depending on the type of anesthesia received? (2) Do 90-day emergency department returns and hospital readmissions differ based on anesthetic technique after geriatric hip fracture repairs? (3) Do 90-day Agency for Healthcare Research and Quality (AHRQ) outcomes differ according to anesthetic techniques used during hip fracture surgery? Methods: We conducted a retrospective study on geriatric patients (65 years or older) with hip fractures between 2009 and 2014 using the Kaiser Permanente Hip Fracture Registry. A total of 1995 (11%) of the surgically treated patients with hip fracture were excluded as a result of missing anesthesia information. The final study sample consisted of 16,695 patients. Of these, 2027 (12%) died and 98 (< 1%) terminated membership during followup, which were handled as competing events and censoring events, respectively. Ninety-day mortality, emergency department returns, hospital readmission, deep vein thrombosis (DVT) or pulmonary embolism (PE), myocardial infarction (MI), and pneumonia were evaluated using multivariable competing risk proportional subdistribution hazard regression according to type of anesthesia technique: general anesthesia, regional anesthesia, or conversion from regional to general. Of the 16,695 patients, 58% (N = 9629) received general anesthesia, 40% (N = 6597) received regional anesthesia, and 2.8% (N = 469) patients were converted from regional to general. Results: Compared with regional anesthesia, patients treated with general anesthesia had a higher likelihood of overall 90-day mortality (hazard ratio [HR], 1.22; 95% confidence interval [CI], 1.11-1.35; p < 0.001); however, when stratified by before and after hospital discharge but within 90 days of surgery, this higher risk was only observed during the inpatient stay (HR, 3.83; 95% CI, 3.18-4.61; p < 0.001); no difference was observed after hospital discharge (HR, 1.04; 95% CI, 0.94-1.16; p = 0.408). Patients undergoing conversion from regional to general also had a higher overall mortality risk compared with those undergoing regional anesthesia (HR, 1.34; 95% CI 1.04-1.74; p = 0.026), but this risk was only observed during their inpatient stay (HR, 6.84; 95% CI, 4.21-11.11; p < 0.001) when stratifying by before and after hospital discharge. Patients undergoing general anesthesia had a higher risk for all-cause readmission when compared with regional anesthesia (HR, 1.09; 95% CI, 1.01-1.19; p = 0.026). No differences according to anesthesia type were observed for risk of 90-day AHRQ outcomes, including DVT/PE, MI, and pneumonia. Conclusions: We found the use of general anesthesia and conversion from regional to general anesthesia were associated with a higher risk of mortality during the in-hospital stay compared with regional anesthetic techniques, but this higher risk did not persist after hospital discharge. We also found general anesthesia to be associated with a higher risk of all-cause readmission compared with regional, but no other differences were observed in risk for complications. Our findings suggest regional anesthetic techniques may be preferred when possible in this patient population. Level of Evidence: Level III, therapeutic study.

Perioperative care delivery is a patient-centered, multidisciplinary process. It relies heavily on synchronized teamwork from a well-coordinated team. Perioperative physicians-surgeons and anesthesiologists-face enormous challenges in surgical care delivery due to changing work environments, post-COVID consequences, shift work disorder, value conflict, escalating demands, regulatory complexity, and financial uncertainties. Physician burnout in this working environment has become increasingly prevalent. It is not only harmful to physicians' health and well-being, but it also affects the quality and safety of patient care. Additionally, the economic costs associated with physician burnout are untenable due to the high turnover rate, high recruitment expenses, and potential early permanent exit from medical practice. In this deteriorating environment of unbalanced physician supply/demand, recognizing, managing, and preventing physician burnout may help preserve the system's most valuable asset and contribute to higher quality and safety of patient care. Leaders in government agencies, health care systems, and organizations must work together to re-engineer the health care system for better physicians and patient care.

Microaggression is widespread in the health care industry and occurs in every health care delivery setting. It comes in many forms, from subtle to obvious, unconscious to conscious, and verbal to behavioral. Women and minority groups (eg, race/ethnicity, age, gender, sexual orientation) are often marginalized during medical training and subsequent clinical practice. These contribute to the development of psychologically unsafe working environments and widespread physician burnout. Physicians experiencing burnout who work in unsafe psychological environments impact the safety and quality of patient care. In turn, these conditions impose high costs on the health care system and organizations. Microaggressions and psychological unsafe work environments are intricately related and mutually enhanced. Therefore, addressing both simultaneously is a good business practice and a responsibility for any health care organization. Additionally, addressing them can reduce physician burnout, decrease physician turnover, and improve the quality of patient care. To counter microaggression and psychological unsafe, it takes conviction, initiative, and sustainable efforts from individuals, bystanders, organizations, and government agencies.

Objectives: To determine the impact of anesthesia type on in-hospital mortality and morbidity for geriatric fragility hip fracture surgery. Design: Retrospective cohort study. Setting: Integrates health care delivery system across 38 facilities in the United States. Patients/Participants: We identified 16,695 patients 65 years of age and older who underwent emergent hip fracture repairs between 2009 and 2014 through the Kaiser Permanente hip fracture registry and excluded pathologic or bilateral fractures. Intervention: Hip fracture surgery with general or regional anesthesia. Main Outcomes Measures: Data on in-hospital mortality, time to death, discharge disposition, and length of stay (LOS) were analyzed among the following anesthesia types: general anesthesia (GA), regional anesthesia (RA), and intraoperative conversions from regional to general (Cv). Results: Compared with RA, the hazard ratio for GA for in-hospital mortality was 1.38 and 2.23 for the Cv group; the time ratio for GA-associated time to death was 0.97 and 0.89 for the Cv group. The GA-associated time ratio for LOS before discharge was 1.01, and the hazard ratio for home discharge was 0.86, but no significance was found with the Cv group. Conclusions: RA may offer advantages over GA for fragility hip fracture surgeries when possible. In-hospital mortality, time to death, increased LOS, and discharge to an institute rather than home were all adversely influenced by GA. Furthermore, the previously understudied Cv group demonstrated adverse outcomes for in-hospital mortality and time to death. Level of Evidence: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Importance: Maternal labor epidural analgesia (LEA) and oxytocin use for labor and delivery have been reported to be associated with child autism spectrum disorders (ASD). However, it remains unclear whether these 2 common medications used during labor and delivery have synergistic associations with ASD risk in children.Objective: To assess the independent associations of LEA and oxytocin during labor and delivery with ASD, as well as outcome modification associated with the concurrent use of both interventions.Design, Setting, and Participants: Data for this cohort study included 205 994 singleton births with vaginal deliveries in a single integrated health care system in Southern California from calendar years 2008 to 2017. Children were followed up to December 31, 2021. Data on use of LEA and oxytocin, covariates, and ASD outcome in children were obtained from electronic medical records. Cox proportional hazards regression was used to estimate the hazard ratios (HRs) adjusting for covariates.Exposures: Labor epidural analgesia and/or oxytocin use during labor and delivery.Main Outcomes and Measures: A child’s clinical diagnosis of ASD during follow-up and at age of diagnosis.Results: Among the cohort, 153 880 children (74.7%) were exposed to maternal LEA and 117 808 children (57.2%) were exposed to oxytocin during labor and delivery. The population of children was approximately half boys and half girls. The median (IQR) age of the mothers was 30.8 (26.8-34.5) years for those not exposed to LEA, 30.0 (25.9-33.8) years for those exposed to LEA, 30.4 (26.5-34.1) years for those unexposed to oxytocin, and 30.0 (25.9-33.9) years for those exposed to oxytocin during labor and delivery. A total of 5146 children (2.5%) had ASD diagnosed during follow-up. Oxytocin exposure was higher among LEA-exposed (67.7%) than -unexposed (26.1%) children. The ASD risk associated with LEA was independent of oxytocin exposure (HR, 1.28; 95% CI, 1.18-1.38); however, the ASD risk associated with oxytocin was not significant after adjusting for LEA exposure (HR, 1.05; 95% CI, 0.99-1.12). A significant interaction of LEA and oxytocin on child ASD risk was found (P = .02 for interaction). Compared with no exposure, HRs were 1.20 (95% CI, 1.09-1.32) for LEA alone, 1.30 (95% CI, 1.20-1.42) for both LEA and oxytocin, and 0.90 (95% CI, 0.78-1.04) for oxytocin alone.Conclusions and Relevance: The findings of this cohort study suggest an association between maternal LEA and ASD risk in children, and the risk appeared to be further increased if oxytocin was also administered. Oxytocin exposure without LEA exposure was not associated with ASD risk in children. These findings must be interpreted with caution. Further studies are needed to replicate or refute the study results and examine biological plausibility.
