During the past 70 years, patient safety science has evolved through four organizational frameworks known as Safety-0, Safety -1, Safety-2, and Safety-3. Their evolution reflects the realization over time that blaming people, chasing errors, fixing one-offs, and regulation would not create the desired patient safety. In Safety-0, the oldest framework, harm events arise from clinician failure; event prevention relies on better staffing, education, and basic standards. In Safety-1, used by hospitals, harm events arise from individual and/or system failures. Safety is improved through analytics, workplace culture, high reliability principles, technology, and quality improvement. Safety-2 emphasizes clinicians' adaptability to prevent harm events in an everchanging environment, using resilience engineering principles. Safety-3, used by aviation, adds system design and control elements to Safety-1 and Safety-2, deploying human factors, design-thinking, and operational control or feedback to prevent and respond to harm events. Safety-3 represents a potential way for anesthesia and perioperative care to become safer., (Copyright © 2024 American Society of Anesthesiologists. All Rights Reserved.)

Introduction: Women continue to be underrepresented in academic anesthesiology. This study assessed guidelines in anesthesia journals over the past 5 years, evaluating differences in woman-led versus man-led guidelines in terms of author gender, quality, and changes over time. We hypothesized that anesthesia guidelines would be predominately man-led, and that there would be differences in quality between woman-led versus man-led guidelines., Methods: All clinical practice guidelines published in the top 10 anesthesia journals were identified as per Clarivate Analytics Impact Factor between 2016 and 2020. Fifty-one guidelines were included for author, gender, and quality analysis using the Appraisal of Guidelines for Research & Evaluation (AGREE) II instrument. Each guideline was assessed across 6 domains and 23 items and given an overall score, overall quality score, and overall rating/recommendation. Stratified and trend analyses were performed for woman-led versus man-led guidelines., Results: Fifty out of 51 guidelines were included: 1 was excluded due to unidentifiable first-author gender. In total, 255 of 1052 (24%) authors were women, and woman-led guidelines (woman-first author) represented 12 of 50 (24%) overall guidelines. Eighteen percent (9 of 50) of guidelines had all-male authors, and a majority (26 of 50, 52%) had less than one-third of female authors. The overall number and percentage of woman-led guidelines did not change over time. There was a significantly higher percentage of female authors in woman-led versus man-led guidelines, median 39% vs 20% ( P = .012), as well as a significantly higher number of female coauthors in guidelines that were woman-led median 3.5 vs 1.0, P = .049. For quality, there was no significant difference in the overall rating or objective quality of woman- versus man-led guidelines. However, there was a significant increase in the overall rating of all the guidelines over time ( P = .010), driven by the increase in overall rating among man-led guidelines, P = .002. The overall score of guidelines did not increase over time; however, they increased in man-led but not woman-led guidelines. There was no significant correlation between the percentage of female authors per guideline and either overall score or overall rating., Conclusions: There is a substantial disparity in the number of women leading and contributing to guidelines which has not improved over time. Woman-led guidelines included more women and a higher percentage of women. There was no difference in quality of guidelines by first-author gender or percentage of female authors. Further systematic and quota-driven sponsorship is needed to promote gender equity, diversity, and inclusion in anesthesia guidelines., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2024 International Anesthesia Research Society.)

Purpose of Review: Traumatic brain injury (TBI) presents complex clinical challenges, requiring a nuanced understanding of its pathophysiology and current management principles to improve patient outcomes. Anesthetists play a critical role in care and need to stay updated with recent evidence and trends to ensure high-quality treatment. The Brain Trauma Foundation Guidelines, last updated in 2016, have shown moderate adherence, and much of the current management relies on expert opinions. This literature review synthesizes the current evidence and provides insights into the role of anesthetists in TBI management., Recent Findings: Recent literature has emphasized the importance of tailored anesthetic management principles in treating TBI, focusing on minimizing secondary brain injury during neurosurgical interventions or extracranial surgery. Emerging trends include individualized intracranial pressure approaches and multimodal neuromonitoring for comprehensive assessment of cerebral physiology., Summary: Anesthesia for TBI patients requires a comprehensive approach that balances anesthetic goals with the unique pathophysiological factors of brain injury. Despite recent research expanding our understanding, challenges remain in standardizing protocols and addressing individual patient response variability. Adherence to established management principles, personalized approaches, and ongoing research is crucial for improving the outcomes., (Copyright © 2024 Wolters Kluwer Health, Inc.

This consensus statement is a comprehensive update of the 2010 Society for Ambulatory Anesthesia (SAMBA) Consensus Statement on perioperative blood glucose management in patients with diabetes mellitus (DM) undergoing ambulatory surgery. Since the original consensus guidelines in 2010, several novel therapeutic interventions have been introduced to treat DM, including new hypoglycemic agents and increasing prevalence of insulin pumps and continuous glucose monitors. The updated recommendations were developed by an expert task force under the provision of SAMBA and are based on a comprehensive review of the literature from 1980 to 2022. The task force included SAMBA members with expertise on this topic and those contributing to the primary literature regarding the management of DM in the perioperative period. The recommendations encompass preoperative evaluation of patients with DM presenting for ambulatory surgery, management of preoperative oral hypoglycemic agents and home insulins, intraoperative testing and treatment modalities, and blood glucose management in the postanesthesia care unit and transition to home after surgery. High-quality evidence pertaining to perioperative blood glucose management in patients with DM undergoing ambulatory surgery remains sparse. Recommendations are therefore based on recent guidelines and available literature, including general glucose management in patients with DM, data from inpatient surgical populations, drug pharmacology, and emerging treatment data. Areas in need of further research are also identified. Importantly, the benefits and risks of interventions and clinical practice information were considered to ensure that the recommendations maintain patient safety and are clinically valid and useful in the ambulatory setting. What Other Guidelines Are Available on This Topic? Since the publication of the SAMBA Consensus Statement for perioperative blood glucose management in the ambulatory setting in 2010, several recent guidelines have been issued by the American Diabetes Association (ADA), the American Association of Clinical Endocrinologists (AACE), the Endocrine Society, the Centre for Perioperative Care (CPOC), and the Association of Anaesthetists of Great Britain and Ireland (AAGBI) on DM care in hospitalized patients; however, none are specific to ambulatory surgery. How Does This Guideline Differ From the Previous Guidelines? Previously posed clinical questions that were outdated were revised to reflect current clinical practice. Additional questions were developed relating to the perioperative management of patients with DM to include the newer therapeutic interventions., Competing Interests: Conflicts of Interest: See Disclosures at the end of the article., (Copyright © 2024 International Anesthesia Research Society.)

The landscape of ambulatory surgery is changing, and tonsillectomy with or without adenoidectomy is one of the most common pediatric surgical procedures performed nationally. The number of children undergoing tonsillectomy on an ambulatory basis continues to increase. The 2 most common indications for tonsillectomy are recurrent throat infections and obstructive sleep-disordered breathing. The most frequent early complications after tonsillectomy are hemorrhage and ventilatory compromise. In areas lacking a dedicated children's hospital, these cases are managed by a nonpediatric specialized anesthesiologist and general otolaryngology surgeon. In response to requests from our members without pediatric fellowship training and/or who care for pediatric patients infrequently, the Pediatric Committee of the Society for Ambulatory Anesthesia (SAMBA) developed a position statement with recommendations for the safe perioperative care of pediatric patients undergoing tonsillectomy with and without adenoidectomy in freestanding ambulatory surgical facilities. This statement identifies children that are more likely to experience complications and to require additional dedicated provider time that is not conducive to the rapid pace and staffing ratios of many freestanding ambulatory centers with mixed adult and pediatric practices. The aim is to provide health care professionals with practical criteria and suggestions based on the best available evidence. When high-quality evidence is unavailable, we relied on group consensus from pediatric ambulatory specialists in the SAMBA Pediatric Committee. Consensus recommendations were presented to the Pediatric Committee of SAMBA., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2024 International Anesthesia Research Society.)

Organization of healthcare strongly differs between European countries and results in country-specific requirements in postgraduate medical training. Within the European Union (EU), the European Board of Anaesthesiology has set recommendations of training for the Specialty of Anaesthesiology including standards for Postgraduate Medical Specialist training including a description for providing service in pediatric anesthesia. However, these standards are advisory and not mandatory. Here we aimed to review the current state and associated challenges of pediatric anesthesia training in Europe. We report an important country-specific variability both in training and regulations of practice of pediatric anesthesia in the EU and in the United Kingdom. The requirements for training in pediatric anesthesia varies between nothing specified (Belgium) or providing anesthesia with direct supervision to a minimum of 50 cases below 5 years of age (Germany) to 3-6 month clinical practice in a specialized pediatric hospital (France). Likewise, the regulations for providing anesthesia to children varies from no regulations at all (Belgium) to age specific requirements and centralization of all children below 4 years of age to specified centers (United Kingdom). Officially recognized pediatric anesthesia fellowship programs are not available in most countries of Europe. It remains unclear if and how country-specific differences in pediatric anesthesia training are associated with clinical outcomes in pediatric perioperative care. There is converging interest and support for the establishment of a European pediatric anesthesia curriculum., (© 2024 The Authors. Pediatric Anesthesia published by John Wiley & Sons Ltd.)

The reporting of incidents has a long association with safety in healthcare and anaesthesia, yet many incident reporting systems substantially under-report critical events. Better understanding the underlying reasons for low levels of critical incident reporting can allow such factors to be addressed systematically to arrive at a better reporting culture. However, new forms of automation in anaesthesia also provide powerful new approaches to be adopted in the future., (Copyright © 2024 British Journal of Anaesthesia. Published by Elsevier Ltd.

Purpose of Review: To explore the collaboration between human factors (HFs) experts and clinicians in order to improve perioperative patient safety., Recent Findings: Recent recommendations to integrate human factors into anesthesia in the United Kingdom emphasizes the value of applying disciplines outside of medicine to optimize the patient experience., Summary: Human factors engineering is underutilized worldwide. Patient safety would benefit from collaboration with HF experts to design resilient systems. Healthcare organizations must consider HF to develop and implement user-centered solutions to improve safety for patients and professionals., (Copyright © 2024 Wolters Kluwer Health, Inc.

Purpose of Review: Patient safety in anesthesiology has advanced significantly over the past several decades. The current process of improving care is often based on studying adverse events (AEs) and near misses. However, there is a wealth of information not captured by focusing solely on these events, potentially resulting in missed opportunities for care improvements., Recent Findings: We review terms such as AEs and nonroutine events (NREs), and introduce the concept of unanticipated events (UEs), defined as events that deviate from intended care that may/may not have been caused by error, may/may not be preventable, and may/may not have caused injury to a patient. UEs incorporate AEs in addition to many other anesthetic events not routinely tracked, allowing for trend analysis over time and the identification of additional opportunities for quality improvement. We review both automated and self-reporting tools that currently exist to capture this often-neglected wealth of data. Finally, we discuss the responsibility of quality/safety leaders for data monitoring., Summary: Consistent reporting and monitoring for trends related to UEs could allow departments to identify risks and mitigate harm before it occurs. We review various proposed methods to expand data collection, and recommend anesthesia practices pursue UE tracking through department-specific reporting interfaces., (Copyright © 2024 Wolters Kluwer Health, Inc.

Climate change, environmental degradation, and biodiversity loss are adversely affecting human health and exacerbating existing inequities, intensifying pressures on already strained health systems. Paradoxically, healthcare is a high-polluting industry, responsible for 4.6% of global greenhouse gas emissions and a similar proportion of air pollutants. Perioperative services are among the most resource-intensive healthcare services and are responsible for some unique pollutants. Opportunities exist to mitigate pollution throughout the entire continuum of perioperative care, including those that occur upstream of the operating room in the process of patient selection and optimisation, delivery of anaesthesia and surgery, and the postoperative recovery period. Within a patient-centred, holistic approach, clinicians can advocate for healthy public policies that modify the determinants of surgical illness, can engage in shared decision-making to ensure appropriate clinical decisions, and can be stewards of healthcare resources. Innovation and collaboration are required to redesign clinical care pathways and processes, optimise logistical systems, and address facility emissions. The results will extend beyond the reduction of public health damages from healthcare pollution to the provision of higher value, higher quality, patient-centred care., (Copyright © 2024 British Journal of Anaesthesia.

Purpose of Review: This review explores the timely and relevant applications of machine learning in ambulatory anesthesia, focusing on its potential to optimize operational efficiency, personalize risk assessment, and enhance patient care., Recent Findings: Machine learning models have demonstrated the ability to accurately forecast case durations, Post-Anesthesia Care Unit (PACU) lengths of stay, and risk of hospital transfers based on preoperative patient and procedural factors. These models can inform case scheduling, resource allocation, and preoperative evaluation. Additionally, machine learning can standardize assessments, predict outcomes, improve handoff communication, and enrich patient education., Summary: Machine learning has the potential to revolutionize ambulatory anesthesia practice by optimizing efficiency, personalizing care, and improving quality and safety. However, limitations such as algorithmic opacity, data biases, reproducibility issues, and adoption barriers must be addressed through transparent, participatory design principles and ongoing validation to ensure responsible innovation and incremental adoption., (Copyright © 2024 The Author(s).

Safely anesthetizing patients with left ventricular assist devices (LVADs) can be intimidating, particularly for novice anesthesia providers. Given the variety of complex issues anesthesia providers may encounter with patients, it would be impractical to expect expertise in every population. To combat the inevitable loss of knowledge, education experts recommend active learning techniques, including test-enhanced learning, active recall, and spaced repetition. To that end, this research team created an LVAD Assessment for Anesthesia, or LAmA tool, to be evaluated for content validity by eight experts. The LAmA tool and content validity assessment were distributed to two anesthesiologists and four nurse anesthetists in the cardiothoracic anesthesia department at a hospital in Northeast Ohio, as well as to two outside nursing research experts. Results were analyzed by the research team and the content validity index (CVI) was determined. A CVI of at least 0.875 was required for the tool to be valid, and final scores in the categories of relevance, clarity, and importance were all ≥ 0.9. The data from the validated tool were used to create a pocket reference on LVAD anesthetic management. Both educational assessments and pocket references have the potential to positively impact knowledge retention and patient outcomes, making them excellent clinical resources., Competing Interests: Name: Sarah Margaret-Ruth Srour, DNP, BA, APRN-CRNA Contribution: This author made significant contributions to the conception, synthesis, writing, and final editing and approval of the manuscript to justify inclusion as an author.

Introduction: Preanesthesia teleconsultation helps reduce availability constraints as well as direct and indirect expenses. The TELECAM trial was performed to assess the quality of preanesthesia teleconsultation in terms of clinical parameters evaluation, feasibility, patient satisfaction and preoperative anxiety, and anesthesiologist satisfaction. Methods: TELECAM was an investigator-initiated, prospective, single-center, randomized, controlled, parallel group, evaluator-blinded, open-label study. Patients with a scheduled ambulatory surgery (orthopedic or hand surgery) were randomized into the in-person preanesthesia consultation group or the preanesthesia teleconsultation (conducted at the patient's home or workplace) group. The quality of the teleconsultation was evaluated through agreement on intubation difficulty, predictable mask ventilation difficulty, and American Society of Anesthesiologists (ASA) scores between the preanesthesia consultation and the preanesthesia in-person visit. Results: A total of 241 patients were included, and 208 were considered in the analyses. The feasibility of teleconsultation was high, with a feasibility ratio of 87.5%. The quality of the preanesthesia consultation regarding the evaluation of predictable intubation, mask ventilation difficulties, and ASA score, did not differ between the two groups (p = 0.23, 0.29, and 0.06, respectively). The preoperative satisfaction was higher for patients who had a preanesthesia teleconsultation (p = 0.04). Patients' preoperative anxiety did not differ between the two groups (p = 0.90). The median satisfaction of the anesthesiologists who performed the teleconsultation reached a maximum of 10 (IQR: 8.0; 10.0). Conclusion: This study showed positive results for the quality of preanesthesia teleconsultation on the evaluation of clinical parameters, with high feasibility and satisfaction of the patients and anesthesiologists. The trial was registered in ClinicalTrials (NCT03470896).

Purpose of Review: The integration of artificial intelligence (AI) in nonoperating room anesthesia (NORA) represents a timely and significant advancement. As the demand for NORA services expands, the application of AI is poised to improve patient selection, perioperative care, and anesthesia delivery. This review examines AI's growing impact on NORA and how it can optimize our clinical practice in the near future., Recent Findings: AI has already improved various aspects of anesthesia, including preoperative assessment, intraoperative management, and postoperative care. Studies highlight AI's role in patient risk stratification, real-time decision support, and predictive modeling for patient outcomes. Notably, AI applications can be used to target patients at risk of complications, alert clinicians to the upcoming occurrence of an intraoperative adverse event such as hypotension or hypoxemia, or predict their tolerance of anesthesia after the procedure. Despite these advances, challenges persist, including ethical considerations, algorithmic bias, data security, and the need for transparent decision-making processes within AI systems., Summary: The findings underscore the substantial benefits of AI in NORA, which include improved safety, efficiency, and personalized care. AI's predictive capabilities in assessing hypoxemia risk and other perioperative events, have demonstrated potential to exceed human prognostic accuracy. The implications of these findings advocate for a careful yet progressive adoption of AI in clinical practice, encouraging the development of robust ethical guidelines, continual professional training, and comprehensive data management strategies. Furthermore, AI's role in anesthesia underscores the need for multidisciplinary research to address the limitations and fully leverage AI's capabilities for patient-centered anesthesia care., (Copyright © 2024 Wolters Kluwer Health, Inc.

Purpose of Review: Given the rapid growth of nonoperating room anesthesia (NORA) in recent years, it is essential to review its unique challenges as well as strategies for patient selection and care optimization., Recent Findings: Recent investigations have uncovered an increasing prevalence of older and higher ASA physical status patients in NORA settings. Although closed claim data regarding patient injury demonstrate a lower proportion of NORA cases resulting in a claim than traditional operating room cases, NORA cases have an increased risk of claim for death. Challenges within NORA include site-specific differences, limitations in ergonomic design, and increased stress among anesthesia providers. Several authors have thus proposed strategies focusing on standardizing processes, site-specific protocols, and ergonomic improvements to mitigate risks., Summary: Considering the unique challenges of NORA settings, meticulous patient selection, risk stratification, and preoperative optimization are crucial. Embracing data-driven strategies and leveraging technological innovations (such as artificial intelligence) is imperative to refine quality control methods in targeted areas. Collaborative efforts led by anesthesia providers will ensure personalized, well tolerated, and improved patient outcomes across all phases of NORA care., (Copyright © 2024 Wolters Kluwer Health, Inc.

Monitoring the patient's physiological functions is critical in clinical anesthesia. The latest version of the Japanese Society of Anesthesiologists' Guidelines for Safe Anesthesia Monitoring, revised in 2019, covers various factors, including electroencephalogram monitoring, oxygenation, ventilation, circulation, and muscle relaxation. However, with recent advances in monitoring technologies, the information provided has become more detailed, requiring practitioners to update their knowledge. At a symposium organized by the Journal of Anesthesia in 2023, experts across five fields discussed their respective topics: anesthesiologists need to interpret not only the values displayed on processed electroencephalogram monitors but also raw electroencephalogram data in the foreseeable future. In addition to the traditional concern of preventing hypoxemia, monitoring for potential hyperoxemia and the effects of mechanical ventilation itself will become increasingly important. The importance of using AI analytics to predict hypotension, assess nociception, and evaluate microcirculation may increase. With the recent increase in the availability of neuromuscular monitoring devices in Japan, it is important for anesthesiologists to become thoroughly familiar with the features of each device to ensure its effective use. There is a growing desire to develop and introduce a well-organized, integrated "single screen" monitor., (© 2024. The Author(s) under exclusive licence to Japanese Society of Anesthesiologists.)

Purpose: Although most anesthetic drugs are classified as compatible with breastfeeding, literature shows that anesthesia providers routinely advise patients to discard milk when receiving all types of anesthesia. The purpose of this project was to determine if a multimodal educational module and cognitive aid improved student registered nurse anesthetists' knowledge and confidence to counsel lactating patients on current anesthesia-related recommendations., Design: This project used a pre-experimental one-group, pretest and post-test design., Methods: Preintervention and postintervention surveys measured knowledge and confidence to counsel lactating patients scheduled to receive anesthesia., Findings: Significant improvement in knowledge and confidence after the intervention were noted., Conclusions: A multimodal educational session and cognitive aid improved student registered nurse anesthetists' knowledge about current anesthesia-related breastfeeding recommendations and their confidence in counseling these patients. Wider use of this educational module with the cognitive aid has the potential to positively impact breastfeeding patients and their children., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The American Society of PeriAnesthesia Nurses.

Background: Many serious adverse events in anaesthesia are retrospectively rated as preventable. Anonymous reporting of near misses to a critical incident reporting system (CIRS) can identify structural weaknesses and improve quality, but incidents are often underreported., Methods: This prospective qualitative study aimed to identify conceptions of a CIRS and reasons for underreporting at a single Swiss centre. Anaesthesia cases were screened to identify critical airway-related incidents that qualified to be reported to the CIRS. Anaesthesia providers involved in these incidents were individually interviewed. Factors that prevented or encouraged reporting of critical incidents to the CIRS were evaluated. Interview data were analysed using the Framework method., Results: Of 3668 screened airway management procedures, 101 cases (2.8%) involved a critical incident. Saturation was reached after interviewing 21 anaesthesia providers, who had been involved in 42/101 critical incidents (41.6%). Only one incident (1.0%) had been reported to the CIRS, demonstrating significant underreporting. Interviews revealed highly variable views on the aims of the CIRS with an overall high threshold for reporting a critical incident. Factors hindering reporting of cases included concerns regarding identifiability of the reported incident and involved healthcare providers., Conclusions: Methods to foster anonymity of reporting, such as by national rather than departmental critical incident reporting system databases, and a change in culture is required to enhance reporting of critical incidents. Institutions managing a critical incident reporting system need to ensure timely feedback to the team regarding lessons learned, consequences, and changes to standards of care owing to reported critical incidents. Consistent reporting and assessment of critical incidents is required to allow the full potential of a critical incident reporting system., (Copyright © 2024 The Authors. Published by Elsevier Ltd..

Purpose of Review: This review explores the intricacies of ethical anesthesia, exploring the necessity for precision anesthesia and its impact on patient-reported outcomes. The primary objective is to advocate for a defined aim, promoting the implementation of rules and feedback systems. The ultimate goal is to enhance precision anesthesia care, ensuring patient safety through the implementation of a teamwork and the integration of feedback mechanisms., Recent Findings: Recent strategies in the field of anesthesia have evolved from intraoperative monitorization to a wider perioperative patient-centered precision care. Nonetheless, implementing this approach encounters significant obstacles. The article explores the evidence supporting the need for a defined aim and applicable rules for precision anesthesia's effectiveness. The implementation of the safety culture is underlined. The review delves into the teamwork description with structured feedback systems., Summary: Anesthesia is a multifaceted discipline that involves various stakeholders. The primary focus is delivering personalized precision care. This review underscores the importance of establishing clear aims, defined rules, and fostering effective and well tolerated teamwork with accurate feedback for improving patient-reported outcomes. The Safe Brain Initiative approach, emphasizing algorithmic monitoring and systematic follow-up, is crucial in implementing a fundamental and standardized reporting approach within patient-centered anesthesia care practice., (Copyright © 2024 Wolters Kluwer Health, Inc.

Purpose: In this project, we sought to develop and implement pediatric anesthesia metrics into electronic health records (EHR) in a hospital setting to improve quality and safety of patient care. While there has been an upsurge in metric-driven health care, specific metrics catering to pediatric anesthesia remain lacking despite widespread use of EHR. The rapid proliferation and implementation of EHR presents opportunities to develop and implement metrics appropriate to local patient care, in this case pediatric anesthesia, with the strategic goal of enhancing quality and safety of patient care, while also delivering transparency in reporting of such metrics., Clinical Features: Using a quasi-nominal consensus group design, we collected requirements from attending anesthesiologists using Agile methodology. Forty-five metrics addressing quality of care (e.g., induction experience, anesthesia delivery, unanticipated events, and postanesthetic care unit stay) and provider performance (e.g., bundle-compliance, collaboration, skills assurance) were developed. Implementation involved integration into the EHR followed by transition from PDF-based feedback to interactive Power BI (Microsoft Corporation, Redmond, WA, USA) dashboards., Conclusion: We introduced and implemented customized pediatric anesthesia metrics within an academic pediatric hospital; however, this framework is easily adaptable across multiple clinical specialties and institutions. In harnessing data-collecting and reporting properties of EHR, the metrics we describe provide insights that facilitate real-time monitoring and foster a culture of continuous learning in line with strategic goals of high-reliability organizations., (© 2024.

Purpose: The purpose of this project was to develop a plan and then implement a process for improving anesthesia delivery at a surgery center in the Southeast United States over a 2-month period., Design: The design of the project was based on utilization of the instrument QoR-15 (Quality of recovery - 15 item questionnaire). This tool is a valid and reliable instrument for the measurement of postoperative outcomes. The QoR-15 includes 15 questions that can each be scored on a 10-point scale., Methods: Methods included a literature search, collecting pre-assessment data, making phone calls to patients utilizing QoR-15 tool, analyzing data, presenting findings to stakeholders, creating a plan of future anesthesia care adjustments., Findings: The results revealed the following outcome data: a total of 183 postoperative phone calls were successfully performed. The calls were completed on the first postoperative day during the months of July and August 2021. There were 459 total cases during this 2-month period with 113 successful patient contacts (24.6 % successful contact rate). Mean scores of the QoR-15 data for the total population were above 9 for all 15 items. The data was then analyzed according to surgical specialty. The category of moderate pain scores in patients from the General and Ophthalmology surgical specialties were 7.9 and 7.8 respectively. General surgery patients also had one of the highest scores in severe pain with a mean of 8.7., Conclusions: In conclusion, the leadership team at the ASC received a formal presentation of the results and recommendations for future adjustments that could be potentially implemented in anesthesia care. The benefits of regional anesthesia were suggested to help achieve better patient pain outcomes in both the General and Ophthalmologic surgical populations., Competing Interests: Declaration of Competing Interest None to report., (Copyright © 2024 The American Society of PeriAnesthesia Nurses.

Purpose of Review: Nonobstetric surgery during pregnancy is associated with maternal and fetal risks. Several physiologic changes create unique challenges for anesthesiologists. This review highlights physiologic changes of pregnancy and presents clinical recommendations based on recent literature to guide anesthetic management for the pregnant patient undergoing nonobstetric surgery., Recent Findings: Nearly every anesthetic technique has been safely used in pregnant patients. Although it is difficult to eliminate confounding factors, exposure to anesthetics could endanger fetal brain development. Perioperative fetal monitoring decisions require an obstetric consult based on anticipated maternal and fetal concerns. Given the limitations of fasting guidelines, bedside gastric ultrasound is useful in assessing aspiration risk in pregnant patients. Although there is concern about appropriateness of sugammadex for neuromuscular blockade reversal due its binding to progesterone, preliminary literature supports its safety., Summary: These recommendations will equip anesthesiologists to provide safe care for the pregnant patient and fetus undergoing nonobstetric surgery., (Copyright © 2024 Wolters Kluwer Health, Inc.

Purpose of Review: Gender-affirming surgery (GAS) is an effective, well studied, and often necessary component of gender-affirming care and mitigation of gender dysphoria for transgender and gender-diverse (TGD) individuals. GAS is categorized as chest surgeries, genitourinary surgeries, facial feminization/masculinization, and vocal phonosurgery. Despite increased incidence of GAS during recent years, there is a gap in knowledge and training on perioperative care for TGD patients., Recent Findings: Our review discusses the relevant anesthetic considerations for the most common GAS, which often involve highly specialized surgical techniques that have unique implications for the anesthesia professional., Summary: Anesthesiology professionals must attend to the surgical and anesthetic nuances of various GAS procedures. However, as many considerations are based on common practice, research is warranted on anesthetic implications and outcomes of GAS., (Copyright © 2024 Wolters Kluwer Health, Inc.

Introduction and Objectives: Cataract surgery is one of the most common procedures in outpatient surgery units. The use of information and communication technologies (ICT) in clinical practice and the advent of new health scenarios, such as the Covid pandemic, have driven the development of pre-anaesthesia assessment models that free up resources to improve access to cataract surgery without sacrificing patient safety. The approach to cataract surgery varies considerably among public, subsidised and private hospitals. This raises the need for guidelines to standardise patient assessment, pre-operative tests, management of background medication, patient information and informed consent., Results: In this document, the SEDAR Clinical Management Division together with the Major Outpatient Surgery Division SEDAR Working Group put forward a series of consensus recommendations on pre-anaesthesia testing based on the use of ITCs, health questionnaires, patient information and informed consent supervised and evaluated by an anaesthesiologist., Conclusions: This consensus document will effectivise pre-anaesthesia assessment in cataract surgery while maintaining the highest standards of quality, safety and legality., (Copyright © 2024 Sociedad Española de Anestesiología, Reanimación y Terapéutica del Dolor.

Objective: Internet-based patient education materials (PEMs) are often above the recommended sixth grade reading level recommended by the U.S. Department of Health and Human Services. In 2016 the U.S. Food and Drug Administration (FDA) released a warning statement against use of general anesthetic drugs in children and pregnant women due to concerns about neurotoxicity. The aim of this study is to evaluate readability, content, and quality of Internet-based PEMs on anesthesia in the pediatric population and neurotoxicity., Study Design: The websites of U.S. medical centers with pediatric anesthesiology fellowship programs were searched for PEMs pertaining to pediatric anesthesia and neurotoxicity. Readability was assessed. PEM content was evaluated using matrices specific to pediatric anesthesia and neurotoxicity. PEM quality was assessed with the Patient Education Material Assessment Tool for Print. A one-sample t -test was used to compare the readability of the PEMs to the recommended sixth grade reading level., Results: We identified 27 PEMs pertaining to pediatric anesthesia and eight to neurotoxicity. Mean readability of all PEMs was greater than a sixth grade reading ( p <0.001). While only 13% of PEMs on anesthesia for pediatric patient mentioned the FDA warning, 100% of the neurotoxicity materials did. PEMs had good understandability (83%) and poor actionability (60%)., Conclusion: The readability, content, and quality of PEMs are poor and should be improved to help parents and guardians make informed decisions about their children's health care., Key Points: · The FDA issued a warning statement against the use of general anesthetic drugs in children and pregnant women.. · Readability, content, and quality of Internet-based patient education materials on the topic of neurotoxicity are poor.. · Improving the readability, content, and quality of PEMs could aid parents in making important health care decisions.., Competing Interests: P.T., MD, MPH was supported by grants from the Agency for Healthcare Research and Quality and National Institute on Minority Health and Health Disparities (R03MD011628, R03HS025267, and R18HS026169).

Purpose: Improvement in delivery of perioperative care depends on the ability to measure outcomes that can direct meaningful changes in practice. We sought to identify and provide an overview of perioperative quality indicators specific to the practice of anesthesia in noncardiac surgery., Source: We conducted an umbrella review (a systematic review of systematic reviews) according to Joanna Briggs Institute methodology. We included systematic reviews examining perioperative indicators in patients ≥ 18 yr of age undergoing noncardiac surgery. Our primary outcome was any quality indicator specific to anesthesia. Indicators were classified by the Donabedian system and perioperative phase of care. The quality of systematic reviews was assessed using AMSTAR 2 criteria. Level of evidence of quality indicators was stratified by the Oxford Centre for Evidence-Based Medicine Classification., Principal Findings: Our search returned 1,475 studies. After removing duplicates and screening of abstracts and full texts, 23 systematic reviews encompassing 3,164 primary studies met our inclusion criteria. There were 330 unique quality indicators. Process indicators were most common (n = 169), followed by outcome (n = 114) and structure indicators (n = 47). Few identified indicators were supported by high-level evidence (45/330, 14%). Level 1 evidence supported indicators of antibiotic prophylaxis (1a), venous thromboembolism prophylaxis (1a), postoperative nausea/vomiting prophylaxis (1b), maintenance of normothermia (1a), and goal-directed fluid therapy (1b)., Conclusion: This umbrella review highlights the scarcity of perioperative quality indicators that are supported by high quality evidence. Future development of quality indicators and recommendations for outcome measurement should focus on metrics that are supported by level 1 evidence. Potential targets for evidence-based quality-improvement programs in anesthesia are identified herein., Study Registration: PROSPERO (CRD42020164691); first registered 28 April 2020., (© 2024.

Introduction: Applying basic standards of anesthesia care is crucial. Patients’ status should be evaluated based on a standard checklist. In case of mismanagement, logical approaches must be conducted. The main objective of the present study is to develop a checklist for evaluation of implementing anesthesia care standards, and its application by observing the practice of anesthesiologists and their residents in Guilan Medical University hospitals. Methods: At first, different stages of anesthesia from patients’ arrival to the operating room till discharge from the recovery room were determined. In every stage, standard protocols were prepared. Then, the checklist items were developed based on anesthesia reference books and the modifications made according to Guilan anesthesiologists and conditions of university hospitals. After that, the adherence of twenty anesthesiologists and residents to these protocols were insensibly observed and scored for six months. Data were analyzed and frequency distribution was presented. Results: Rate of not-applied standards in descending orders was: 52.5% in preparation of operating room, 42.2% in pre-intubation, 40% in pre-extubation, 34.5% during maintenance of anesthesia,33.3% at discharge from the recovery room, 27.7% after intubation, 27.2% before arrival to the recovery room, 17.1% in recovery room, 13.8% at the time of intubation, 11.3% at arrival to the recovery room, 10% upon admission to the recovery room, 9% upon extubation, and 0% after extubation. Conclusion: This study revealed the necessity of using standard checklist for anesthesia care in operating room to protect the patient and to decrease the risk of anesthesia for them. Based on the results, educational and management interventions should be designed to promote adherence to standards.

Intra-operative hypotension frequently complicates anaesthesia in older patients and is implicated in peri-operative organ hypoperfusion and injury. The prevalence and corresponding treatment thresholds of hypotension are incompletely described in the UK. This study aimed to identify prevalence of intra-operative hypotension and its treatment thresholds in UK practice. Patients aged ≥ 65 years were studied prospectively from 196 UK hospitals within a 48-hour timeframe. The primary outcome was the incidence of hypotension (mean arterial pressure <65 mmHg; systolic blood pressure reduction >20%; systolic blood pressure <100 mmHg). Secondary outcomes included the treatment blood pressure threshold for vasopressors; incidence of acute kidney injury; myocardial injury; stroke; and in-hospital mortality. Additionally, anaesthetists providing care for included patients were asked to complete a survey assessing their intended treatment thresholds for hypotension. Data were collected from 4750 patients. Hypotension affected 61.0% of patients when defined as mean arterial pressure <65 mmHg, 91.3% of patients had >20% reduction in systolic blood pressure from baseline and 77.5% systolic blood pressure <100 mmHg. The mean (SD) blood pressure triggering vasopressor therapy was mean arterial pressure 64.2 (11.6) mmHg and the mean (SD) stated intended treatment threshold from the survey was mean arterial pressure 60.6 (9.7) mmHg. A composite adverse outcome of myocardial injury, kidney injury, stroke or death affected 345 patients (7.3%). In this representative sample of UK peri-operative practice, the majority of older patients experienced intra-operative hypotension and treatment was delivered below suggested thresholds. This highlights both potential for intra-operative organ injury and substantial opportunity for improving treatment of intra-operative hypotension., (© 2021 The Authors.

The Earth's mean surface temperature is already approximately 1.1°C higher than pre-industrial levels. Exceeding a mean 1.5°C rise by 2050 will make global adaptation to the consequences of climate change less possible. To protect public health, anaesthesia providers need to reduce the contribution their practice makes to global warming. We convened a Working Group of 45 anaesthesia providers with a recognised interest in sustainability, and used a three-stage modified Delphi consensus process to agree on principles of environmentally sustainable anaesthesia that are achievable worldwide. The Working Group agreed on the following three important underlying statements: patient safety should not be compromised by sustainable anaesthetic practices; high-, middle- and low-income countries should support each other appropriately in delivering sustainable healthcare (including anaesthesia); and healthcare systems should be mandated to reduce their contribution to global warming. We set out seven fundamental principles to guide anaesthesia providers in the move to environmentally sustainable practice, including: choice of medications and equipment; minimising waste and overuse of resources; and addressing environmental sustainability in anaesthetists' education, research, quality improvement and local healthcare leadership activities. These changes are achievable with minimal material resource and financial investment, and should undergo re-evaluation and updates as better evidence is published. This paper discusses each principle individually, and directs readers towards further important references., (© 2021 The Authors.

Background: Enhancing patient outcomes in an array of surgical procedures in the head and neck requires the maintenance of complex regional functions through the protection of cranial nerve integrity. This review and consensus statement cover the scope of cranial nerve monitoring of all cranial nerves that are of practical importance in head, neck, and endocrine surgery except for cranial nerves VII and VIII within the temporal bone. Complete and applied understanding of neurophysiologic principles facilitates the surgeon's ability to monitor the at-risk nerve., Methods: The American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) identified the need for a consensus statement on cranial nerve monitoring. An AAO-HNS task force was created through soliciting experts on the subject. Relevant domains were identified, including residency education, neurophysiology, application, and various techniques for monitoring pertinent cranial nerves. A document was generated to incorporate and consolidate these domains. The panel used a modified Delphi method for consensus generation., Results: Consensus was achieved in the domains of education needs and anesthesia considerations, as well as setup, troubleshooting, and documentation. Specific cranial nerve monitoring was evaluated and reached consensus for all cranial nerves in statement 4 with the exception of the spinal accessory nerve. Although the spinal accessory nerve's value can never be marginalized, the task force did not feel that the existing literature was as robust to support a recommendation of routine monitoring of this nerve. In contrast, there is robust supporting literature cited and consensus for routine monitoring in certain procedures, such as thyroid surgery, to optimize patient outcomes., Conclusions: The AAO-HNS Cranial Nerve Monitoring Task Force has provided a state-of-the-art review in neural monitoring in otolaryngologic head, neck, and endocrine surgery. The evidence-based review was complemented by consensus statements utilizing a modified Delphi method to prioritize key statements to enhance patient outcomes in an array of surgical procedures in the head and neck. A precise definition of what actually constitutes intraoperative nerve monitoring and its benefits have been provided.

Nocebo refers to non-pharmacological adverse effects of an intervention. Well-intended procedural warnings frequently function as a nocebo. Both nocebo and placebo are integral to the generation of 'real' treatment effects and their associated 'real' side-effects. They are induced or exacerbated by: context; negative expectancy; and negative conditioning surrounding treatment. Since the late 1990s, the neuroscience literature has repeatedly demonstrated that the nocebo effect is mediated by discrete neurobiological mechanisms and specific physiological modulations. Although no single biological mechanism has been found to explain the nocebo effect, nocebo hyperalgesia is thought to initiate from the dorsal lateral prefrontal cortex subsequently triggering the brain's descending pain modulatory system and other pain regulation pathways. Functional magnetic resonance imaging shows that expectation of increased pain is accompanied by increased neural activity in the hippocampus and midcingulate cortex which is not observed when analgesia is expected. Functional magnetic resonance imaging studies have shown that the anterior cingulate cortex is pivotal in the perception of affective pain evoked by nocebo words. Research has also explored neurotransmitters which mediate the nocebo effect. The neuropeptide cholecystokinin appears to play a key role in the modulation of pain by nocebo. Hyperalgesia generated by nocebo also increases the activity of the hypothalamic-pituitary-adrenal axis as indicated by increases in plasma cortisol. The avoidance or mitigation of nocebo needs to be recognised as a core clinical skill in optimising anaesthesia care. Embracing the evidence around nocebo will allow for phrases such as 'bee sting' and 'sharp scratch' to be thought of as clumsy verbal relics of the past. Anaesthesia as a profession has always prided itself on practicing evidence-based medicine, yet for decades anaesthetists and other healthcare staff have communicated in ways counter to the evidence. The premise of every interaction should be 'primum non nocere' (first, do no harm). Whether the context is research or clinical anaesthesia practice, the nocebo can be ignored no longer., (© 2022 Association of Anaesthetists.)

Surgery and anaesthesia subject the brain to considerable stress in the peri-operative period. This may be caused by potentially neurotoxic anaesthetic drugs, impaired cerebral perfusion and reperfusion injury related to surgery or thromboembolic events. Patient monitoring using electroencephalogram and cerebral oximetry can assist in optimising depth of anaesthesia and assessment of cerebral metabolic activity. However, research findings have been contradictory as to whether these monitors can help ameliorate peri-operative neurocognitive complications. In this narrative review, we will discuss recent evidence in the use of electroencephalography and cerebral oximetry and the underlying scientific principles. It is important to appreciate the raw electroencephalographic changes under anaesthesia and those associated with ageing, in order to interpret depth of anaesthesia indices correctly. Cerebral oximetry is useful not only for the detection of cerebral desaturation but also to identify those patients who are particularly vulnerable to injury, for better risk stratification. An algorithm-based approach may be most effective in managing the episodes of cerebral desaturation., (© 2022 Association of Anaesthetists.)

Objectives: To evaluate current international practice in PICUs regarding components of the "Assessing Pain, Both Spontaneous Awakening and Breathing Trials, Choice of Sedation, Delirium Monitoring/Management, Early Exercise/Mobility, and Family Engagement/Empowerment" (ABCDEF) bundle., Design: Online surveys conducted between 2017 and 2019., Setting: One-hundred sixty-one PICUs across the United States (n = 82), Canada (n = 14), Brazil (n = 27), and Europe (n = 38) participating in the Prevalence of Acute Rehabilitation for Kids in the PICU study., Interventions: None., Measurements and Main Results: Of the 161 participating PICUs, 83% were in academic teaching hospitals and 42% were in free-standing children's hospitals. Median size was 16 beds (interquartile range, 10-24 beds). Only 15 PICUs (9%) had incorporated all six ABCDEF bundle components into routine practice. Standardized pain assessment (A) was the most common (91%), followed by family engagement (F, 88%) and routine sedation assessment (C) with validated scales (84%). Protocols for testing extubation readiness or conducting spontaneous breathing trials (B) were reported in 57%, with 34% reporting a ventilator weaning protocol. Routine delirium monitoring with a validated screening tool (D) was reported by 44% of PICUs, and 26% had a guideline, protocol, or policy for early exercise/mobility (E). Practices for spontaneous breathing trials were variable in 29% of Canadian PICUs versus greater than 50% in the other regions. Delirium monitoring was lowest in Brazilian PICUs (18%) versus greater than 40% in other regions, and family engagement was reported in 55% of European PICUs versus greater than 90% in other regions., Conclusions: ABCDEF bundle components have been adopted with substantial variability across regions. Additional research must rigorously evaluate the efficacy of specific elements with a focus on B, D, E, and full ABCDEF bundle implementation. Implementation science is needed to facilitate an understanding of the barriers to ABCDEF implementation and sustainability with a focus on specific cultural and regional differences., (Copyright © 2021 by the Society of Critical Care Medicine and Wolters Kluwer Health, Inc.

Traumatic brain injury is the alteration in brain function due to an external force. It is common and affects millions of people worldwide annually. The World Health Organization estimates that 90% of global deaths caused by injuries occur in low- and middle-income countries, with traumatic brain injury contributing up to half of these trauma-related deaths. Patients with traumatic brain injury in low- and middle-income countries have twice the odds of dying compared with their counterparts in high-income countries. Sedation is a key element of care in the management of traumatic brain injury, used for its neuroprotective effects and to prevent secondary brain injury. While sedatives have the potential to improve outcomes, they can be challenging to administer and have potentially dangerous complications. Sedation in low-resource settings should aim to be effective, safe, affordable and feasible. In this paper, we summarise the indications for sedation in traumatic brain injury, the choice of sedative drugs and the pragmatic management and monitoring of sedated traumatic brain injury patients in low-resource settings., (© 2022 Association of Anaesthetists.)

Background: The number of patients receiving anaesthesia is increasing, but the impact of general anaesthesia on the patient's immune system remains unclear. The aim of the present study is to investigate dynamics of systemic immune cell responses to anaesthesia during perioperative period at a single-cell solution., Methods: The peripheral blood mononuclear cells (PBMCs) and clinical phenomes were harvested and recorded 1 day before anaesthesia and operation, just after anaesthesia (0 h), and 24 and 48 h after anaesthesia. Single-cell sequencing of PBMCs was performed with 10× genomics. Subsequently, data analysis was performed with R packages: Seurat, clusterProfiler and CellPhoneDB., Results: We found that the cluster of CD56 + NK cells changed at 0 h and the cluster of monocytes increased at 24 and 48 h after anaesthesia. The characteristic genes of CD56 + NK cells were mainly enriched in the Jak-STAT signalling pathway and in cell adhesion molecules (24 h) and carbon metabolism (48 h). The communication between CD14 + monocytes and other cells decreased substantially 0 and 48 h after operation. The number of plasma cells enriched in protein export in men was substantially higher than that in women, although the total number in patients decreased 24 h after operation. CD14 + monocytes dominated that cell-cell communications appeared in females, while CD8 + NKT cells dominated that cell-cell communications appeared in male. The number of plasma cells increased substantially in patients with major surgical trauma, with enrichments of pentose phosphate pathway. The communications between plasma cells with other cells varied between surgical severities and anaesthetic forms. The intravenous anaesthesia caused major alterations of cell types, including CD14 + monocytes, plasmas cells and MAIT cells, as compared with inhalation anaesthesia., Conclusion: We initially reported the roles of perioperative anaesthesia/surgery in temporal phenomes of circulating immune cells at a single-cell solution. Thus, the protection against immune cell changes would benefit the recovery from anaesthesia/surgery., (© 2022 The Authors.

Patients with Parkinson's disease are at higher risk of peri-operative medical and surgical complications. Multidisciplinary management, early recognition of potential complications, specialised care of medications and intra-operative protection of the vulnerable brain are all important aspects of the peri-operative management of patients with Parkinson's disease. Advances in continuous dopaminergic treatment, development of a peri-operative Parkinson's disease pathway and application of telemedicine are starting to play a role in improving peri-operative care. Management of patients with advanced Parkinson's disease is also evolving, with potential for incorporation of integrated care and changes in the anaesthetic management for deep brain stimulation surgery. There are new methods for localisation of target nuclei and increasing insight on the effects of anaesthetic drugs on microelectrode recordings and clinical outcomes. Parkinson's disease is a progressive disease, but management is improving with better peri-operative care for patients., (© 2022 Association of Anaesthetists.)

Introduction: Clinical record (CR) is the primary tool used by healthcare workers (HCWs) to record clinical information and its completeness can help achieve safer practices. CR is the most appropriate source in order to measure and evaluate the quality of care. In order to achieve a safety climate is fundamental to involve a responsive healthcare workforce thorough peer-review and feedbacks. This study aims to develop a peer-review tool for clinical records quality assurance, presenting the seven-year experience in the evolution of it; secondary aims are to describe the CR completeness and HCWs' diligence toward recording information in it., Methods: To assess the completeness of CRs a peer-review tool was developed in a large Academic Hospital of Northern Italy. This tool included measurable items that examined different themes, moments and levels of the clinical process. Data were collected every three months between 2010 and 2016 by appointed and trained HCWs from 42 Units; the hospital Quality Unit was responsible for of processing and validating them. Variations in the proportion of CR completeness were assessed using Cochran-Armitage test for trends., Results: A total of 9,408 CRs were evaluated. Overall CR completeness improved significantly from 79.6% in 2010 to 86.5% in 2016 (p<0.001). Doctors' attitude showed a trend similar to the overall completeness, while nurses improved more consistently (p<0.001). Most items exploring themes, moments and levels registered a significant improvement in the early years, then flattened in last years. Results of the validation process were always above the cut-off of 75%., Conclusions: This peer-review tool enabled the Quality Unit and hospital leadership to obtain a reliable picture of CRs completeness, while involving the HCWs in the quality evaluation. The completeness of CR showed an overall positive and significant trend during these seven years., Competing Interests: The authors have declared that no competing interests exist.
