RESUMO

BACKGROUND: Intraoperative handoffs have been implicated as a contributing factor in many perioperative adverse events. Despite conflicting data around their impact on perioperative outcomes, they remain a vulnerable point in the perioperative system with significant attention focused on improving them. This study aimed to understand the processes in place surrounding the point of information transfer in intraoperative handoffs. METHODS: We used semistructured interviews with anesthesia clinicians to understand the processes and systems surrounding intraoperative handoffs. Interview data were coded deductively using the Systems Engineering Initiative for Patient Safety model as a framework, with subthemes developed inductively. RESULTS: Clinicians do a significant amount of work before and after the point of information transfer to ensure a smooth handoff and safe patient care. Despite not having standardization of handoffs, most clinicians have a typical handoff organization and largely agree on content that should be included. However, there is variability based on clinician and patient characteristics, including clinician discipline and patient acuity. These handoffs are additionally impacted by the overall culture in the operating room, including the teamwork and hierarchies present among the surgical and anesthesia teams. Finally, the broader operating room logistics, including scheduling practices for surgical cases and anesthesia teams, impact the quality of intraoperative handoffs and the ability of clinicians to prepare for these handoffs. CONCLUSIONS: Handoffs involve processes beyond the point of information transfer and are embedded in the systems and culture of the operating rooms. These considerations are important when seeking to improve the quality of intraoperative handoffs.

RESUMO

STUDY OBJECTIVE: Use of cognitive aids during emergencies increases key actions and decreases omissions, both known to save lives. With little known about emergency manual (EM) clinical use, we aimed to help answer "Will EMs be used peri-crisis at a meaningful frequency?" and to explore clinical sustainment. DESIGN: Prospective, observational study. SETTING: Operating Rooms. PATIENTS: All patients undergoing anesthesia at a major academic medical center during the study periods; ∼75,000 cases. INTERVENTION & MEASUREMENTS: To understand the initial and sustainment phases of EM implementation, we placed a question regarding EM use at the end of every anesthetic case to prospectively measure EM use at: implementation, one-year later, and six years post-implementation. MAIN RESULTS: For more than twenty-four thousand cases in each approximately 6-month study period, EMs were used peri-crisis (before, during or after a perioperative crisis) in 145 cases initially (0.55%; SE 0.045%), 42 cases one-year later (0.17%; SE 0.026%), and 57 cases (0.21%; SE 0.028%) six years post-implementation. Peri-crisis EM uses dropped 0.38% (97.5% CI: 0.26%, 0.49%) from initial to one-year post-implementation. After that, peri-crisis EM uses did not differ significantly from one-year to six years post-implementation, showing sustainment [increased 0.04% (97.5% CI: -0.05%, 0.12%)]. Among cases with cardiac arrest or CPR, as a subset proxy for relevant crises, EMs were used in 7/13 such cases initially (54%, SE 13.6%), 8/20 one-year later (40%; SE 10.9%) and 7/13 six years later (54%; SE 13.6%). CONCLUSIONS: After an initial expected drop, EM peri-crisis use six years post-implementation was: sustained without intensive additional efforts, averaged ∼10 times per month at a single institution, and was reported in more than half of cases with cardiac arrest or CPR. Peri-crisis use of EMs is appropriately rare, though for relevant crises can have substantial positive impacts as described in prior literature. The sustained use of EMs may be related to increasing cultural acceptance of EMs, as reflected in survey result trends and broader cognitive aid literature.

RESUMO

Managing a safe and efficient anaesthetic induction within a team involves the challenge of when, if, and how to surface, discuss, and implement the best plan on how to proceed. The Lemke and colleagues study in this issue of the British Journal of Anaesthesia is a unique view into real-world conversations that naturally occur in anaesthesia teams in moments of high task and cognitive load, such as induction of anaesthesia. The study spotlights important small moments of physician, nurse, and trainee team coordination. It illuminates key patterns of conversation in naturally occurring anaesthesia teams, and raises important questions about what the speaking up standard should be and the psychological safety-shaping role consultants play in setting the norms for speaking up.

RESUMO

The expectation by colleagues that fellow clinicians deftly manage the stresses of practice often predisposes healthcare professionals involved in an adverse event to experience isolation, blame, and shame. The peer support model has since been recognized as an important component of institutional wellness and follows a well-described and structured method. Although peer support programs have traditionally been established to support caregivers involved in adverse medical events, the relevance and applicability of these programs have found substantial traction across broader crisis domains. Interventions, including peer support, help mitigate the 3 components of burnout: emotional exhaustion, depersonalization (cynicism), and reduced efficacy.

RESUMO

Debriefing after perioperative crises (eg, cardiac arrest, massive hemorrhage) is a well-described practice that can provide benefits to individuals, teams, and health systems. Debriefing has also been embraced by high-stakes industries outside of health care. Yet, in studies of actual clinical practice, there are many critical events that do not get debriefed. This article explores the gap that exists between principle and reality and the factors and strategies to offer opportunities to reflect on actual critical events, when indicated, across the increasing scope of environments where anesthesia care is provided.

RESUMO

PURPOSE OF REVIEW: Simulation training in obstetric anesthesia has become widespread in recent years. Simulations are used to train staff and trainees, assess and improve team performance, and evaluate the work environment. This review summarizes current research in these categories. RECENT FINDINGS: Simulation to improve individual technical skills has focused on induction of general anesthesia for emergent cesarean delivery, an infrequently encountered scenario by anesthesia trainees. Low- and high-fidelity simulation devices for the learning and practicing neuraxial and non-neuraxial procedures have been described, and both are equally effective. The use of checklists in obstetric emergencies has become common as and post-scenario debriefing techniques have improved. Although participant task performance improves, whether participants retain learned skills or whether simulation improves patient outcomes has not yet been established. Tools to assess teamwork during simulation have been developed, but none have been rigorously validated. In-situ vs. offsite simulations do not differ in effectiveness. SUMMARY: Simulation allows for practice of tasks and teamwork in a controlled manner. There is little data whether simulation improves patient outcomes and metrics to predict the long-term retention of skills by simulation participants have not been developed.

RESUMO

Interprofessional teams work together on the labor and delivery unit, where clinical care is often unscheduled, rapidly evolving, and fast paced. Effective communication is key for coordinated delivery of optimal care and for fostering a culture of community and safety in the workplace. The preoperative huddle allows for information sharing, cross-checking, and preparation before the start of surgery. Postoperative debriefings allow the operative team to engage in ongoing process improvement. Debriefings after adverse events allow for shared understanding, mutual healing, and help mitigating the harm to potential "second victims."

RESUMO

PURPOSE: The authors addressed three questions: (1) Would a realistic simulation-based educational intervention improve speaking-up behaviors of practicing nontrainee anesthesiologists? (2) What would those speaking-up behaviors be when the issue emanated from a surgeon, a circulating nurse, or an anesthesiologist colleague? (3) What were the hurdles and enablers to speaking up in those situations? METHOD: The authors conducted a simulation-based randomized controlled experiment from March 2008-February 2011 at the Center for Medical Simulation, Boston, Massachusetts. During a mandatory crisis management course for practicing nontrainee anesthesiologists from five Boston institutions, a 50-minute workshop on speaking up was conducted for intervention (n = 35) and control (n = 36) groups before or after, respectively, an experimental scenario with three events. The authors analyzed videos of the experimental scenarios and debriefing sessions. RESULTS: No statistically significant differences between the intervention and control group subjects with respect to speaking-up actions were observed in any of the three events. The five most frequently mentioned hurdles to speaking up were uncertainty about the issue, stereotypes of others on the team, familiarity with the individual, respect for experience, and the repercussion expected. The five most frequently mentioned enablers were realizing the speaking-up problem, having a speaking-up rubric, certainty about the consequences of speaking up, familiarity with the individual, and having a second opinion or getting help. CONCLUSIONS: An educational intervention alone was ineffective in improving the speaking-up behaviors of practicing nontrainee anesthesiologists. Other measures to change speaking-up behaviors could be implemented and might improve patient safety.

RESUMO

STATEMENT: The use of deceptive methodology in simulation education is an emerging ethical controversy. At the 2014 International Meeting on Simulation in Healthcare, arguments for and against its use were debated by simulation experts. What emerged from this discussion was an apparent disconnect between current practice and existing empiric research on this subject. At present, no framework exists to guide the simulation community's exploration of this issue of deception.After reviewing the relevant psychological literature, we propose a framework delineating discrete elements and important relationships, which enables a comprehensive view of the factors germane to simulations that use deception. We further comment on key pedagogical and psychological issues in the context of this framework and define an agenda for further research. Educators are encouraged to use this framework when determining whether, when, and how deception might be used and, if used, how it can be ethically justified and carefully implemented.

RESUMO

BACKGROUND: Optimal team performance in the operating room (OR) requires a combination of interactions among OR professionals and adherence to clinical guidelines. Theoretically, it is possible that OR teams could communicate very well but fail to follow acceptable standards of patient care and vice versa. OR simulations offer an ideal research environment to study this relationship. The goal of this study was to determine the relationship between ratings of OR teamwork and communication with adherence to patient care guidelines in a simulated scenarios of malignant hyperthermia (MH). METHODS: An interprofessional research team (2 anesthesiologists, 1 surgeon, an OR nurse, and a social scientist) reviewed videos of 5 intraoperative teams managing a simulated patient who manifested MH while undergoing general anesthesia for an epigastric herniorraphy in a high-fidelity, in situ OR. Participant teams consisted of 2 residents from anesthesiology, 1 from surgery, 1 OR nurse, and 1 certified surgical technician. Teamwork and communication were assessed with 4 published tools: Anesthesiologists' Non-Technical Skills (ANTS), Scrub Practitioners List of Intra-operative Non-Technical Skills (SPLINTS), Non-Technical Skills for Surgeons (NOTSS), and Objective Teamwork Assessment System (OTAS). We developed an evidence-based MH checklist to assess overall patient care. RESULTS: Interrater agreement for teamwork tools was moderate. Average rater agreement was 0.51 For ANTS, 0.67 for SPLINTS, 0.51 for NOTSS, and 0.70 for OTAS. Observer agreement for the MH checklist was high (0.88). Correlations between teamwork and MH checklist were not significant. Teams were different in percent of the MH actions taken (range, 50-91%; P = .006). CONCLUSION: In this pilot study, intraoperative teamwork and communication were not related to overall patient care management. Separating nontechnical and technical skills when teaching OR teamwork is artificial and may even be damaging, because such an approach could produce teams with excellent communication skills as they unsuccessfully manage the patient. OR simulations offer a unique opportunity to research how to best integrate both of these domains to improve patient care.

RESUMO

In this study, we aimed to continuously measure cardiac output (CO) with the electrical velocimetry (EV) method and characterize the hemodynamic profile of patients undergoing spinal anesthesia for elective cesarean delivery (CD), and to discuss the potential benefit of using real time CO monitoring to guide patient management. Forty-two patients scheduled for elective CD under spinal anesthesia were enrolled in this observational study. A non-invasive CO monitor incorporating the electrical velocimetry algorithm, ICON(®) (Cardiotronic(®), La Jolla, California, USA), was used to measure CO and stroke volume (SV) continuously. Peripheral venous pressure was measured intermittently at pre-defined time points. Systemic vascular resistance was calculated retrospectively after completion of the study. Hemodynamic changes at pre-defined time points and caused by phenylephrine administration were analyzed. Hypotension (MAP reduction more than 20% from baseline values) occurred in 71.1% of patients after spinal anesthesia, while the coinstantaneous CO was increased ≥20% from baseline in the majority of patients (76.3%) at the same time. Significant increase in CO took place at 3-2 min before the administration of phenylephrine bolus. Treatment of hypotension with phenylephrine was associated with significant decrease in CO. Continuous CO monitoring with EV enables clinicians to determine CO and SV changes prior to onset of hypotension and to better understand patients' hemodynamics. It is an important addition to the current monitoring. The benefit of routinely using this technique remains to be determined in term of the patient outcomes.

RESUMO

BACKGROUND: Emotional stability is important for individual and team performance during operating room (OR) emergencies. We compared physiologic and psychological anxiety assessments in OR teams during simulated events. METHODS: Twenty-two teams participated in a "cannot intubate/cannot ventilate" simulation. Participants completed the State-Trait Anxiety Inventory and wore a galvanic skin response (GSR) sensor. Differences in State-Trait Anxiety Inventory scores and GSR levels were analyzed. Anxiety scores were correlated with GSR levels. RESULTS: Resident physicians had significantly higher trait anxiety than the nurses, certified registered nurse anesthetists, and surgical technicians (43.9 ± 9.9 vs 38.3 ± 9.3, P < .01). Senior practitioners had significantly higher trait anxiety than junior practitioners (43.7 ± 9.6 vs 40.0 ± 9.9, P = .03). All groups showed significant increases in GSR. Psychological and physiologic data did not correlate. CONCLUSIONS: Senior practitioners and residents have higher levels of baseline trait anxiety for unclear reasons. Also, OR team training results in physiological signs of anxiety that do not correlate to self-reported psychological measurements.

RESUMO

BACKGROUND: High-quality teamwork among operating room (OR) professionals is a key to efficient and safe practice. Quantification of teamwork facilitates feedback, assessment, and improvement. Several valid and reliable instruments are available for assessing separate OR disciplines and teams. We sought to determine the most feasible approach for routine documentation of teamwork in in-situ OR simulations. We compared rater agreement, hypothetical training costs, and feasibility ratings from five clinicians and two nonclinicians with instruments for assessment of separate OR groups and teams. MATERIALS AND METHODS: Five teams of anesthesia or surgery residents and OR nurses (RN) or surgical technicians were videotaped in simulations of an epigastric hernia repair where the patient develops malignant hyperthermia. Two anesthesiologists, one OR clinical RN specialist, one educational psychologist, one simulation specialist, and one general surgeon discussed and then independently completed Anesthesiologists' Non-Technical Skills, Non-Technical Skills for Surgeons, Scrub Practitioners' List of Intraoperative Non-Technical Skills, and Observational Teamwork Assessment for Surgery forms to rate nontechnical performance of anesthesiologists, surgeons, nurses, technicians, and the whole team. RESULTS: Intraclass correlations of agreement ranged from 0.17-0.85. Clinicians' agreements were not different from nonclinicians'. Published rater training was 4 h for Anesthesiologists' Non-Technical Skills and Scrub Practitioners' List of Intraoperative Non-Technical Skills, 2.5 h for Non-Technical Skills for Surgeons, and 15.5 h for Observational Teamwork Assessment for Surgery. Estimated costs to train one rater to use all instruments ranged from $442 for a simulation specialist to $6006 for a general surgeon. CONCLUSIONS: Additional training is needed to achieve higher levels of agreement; however, costs may be prohibitive. The most cost-effective model for real-time OR teamwork assessment may be to use a simulation technician combined with one clinical rater to allow complete documentation of all participants.

RESUMO

BACKGROUND: Although feedback conversations are an essential component of learning, three challenges make them difficult: the fear that direct task feedback will harm the relationship with the learner, overcoming faculty cognitive biases that interfere with their eliciting the frames that drive trainees' performances, and time pressure. Decades of research on developmental conversations suggest solutions to these challenges: hold generous inferences about learners, subject one's own thinking to test by making it public, and inquire directly about learners' cognitive frames. METHODS: The authors conducted a randomized, controlled trial to determine whether a 1-h educational intervention for anesthesia faculty improved feedback quality in a simulated case. The primary outcome was an analysis of the feedback conversation between faculty and a simulated resident (actor) by using averages of six elements of a Behaviorally Anchored Rating Scale and an objective structured assessment of feedback. Seventy-one Harvard faculty anesthesiologists from five academic hospitals participated. RESULTS: The intervention group scored higher when averaging all ratings. Scores for individual elements showed that the intervention group performed better in maintaining a psychologically safe environment (4.3 ± 1.21 vs. 3.8 ± 1.16; P = 0.001), identifying and exploring performance gaps (4.1 ± 1.38 vs. 3.7 ± 1.34; P = 0.048), and they more frequently emphasized the professionalism error of failing to call for help over the clinical topic of anaphylaxis (66 vs. 41%; P = 0.008). CONCLUSIONS: Quality of faculty feedback to a simulated resident was improved in the interventional group in a number of areas after a 1-h educational intervention, and this short intervention allowed a group of faculty to overcome enough discomfort in addressing a professionalism lapse to discuss it directly.

RESUMO

SUMMARY STATEMENT: Medicine is hierarchical, and both positive and negative effects of this can be exposed and magnified during a crisis. Ideally, hierarchies function in an orderly manner, but when an inappropriate directive is given, the results can be disastrous unless team members are empowered to challenge the order. This article describes a case that uses misdirection and the possibility of simulated "death" to facilitate learning among experienced clinicians about the potentially deadly effects of an unchallenged, inappropriate order. The design of this case, however, raises additional questions regarding both ethics and psychological safety. The ethical concerns that surround the use of misdirection in simulation and the psychological ramifications of incorporating patient death in this context are explored in the commentary. We conclude with a discussion of debriefing strategies that can be used to promote psychological safety during potentially emotionally charged simulations and possible directions for future research.

RESUMO

BACKGROUND: Vascular alterations are present in pregnant women affected by preeclampsia. In this study, we assessed arterial compliance in women affected by hypertensive disorders of pregnancy. We hypothesized that arterial compliance is reduced in women affected by preeclampsia. METHODS: Forty-three hypertensive pregnant women undergoing evaluation for preeclampsia were studied. Clinical data about each patient and pregnancy were collected. Large (C1) and small (C2) artery compliance were assessed by radial tonometry, while the patients underwent laboratory tests to diagnose preeclampsia. At the time of delivery, gestational age and newborn data were recorded. RESULTS: Eighteen women were diagnosed with preeclampsia. C2 levels were lower among preeclamptic versus hypertensive aproteinuric women (mean ± SD, 4.5 ± 1.3 vs 5.9 ± 2.3 mL/mm Hg · 100, P = 0.013, 95% confidence interval [CI] of difference 0.32-2.55), whereas C1 levels did not differ. In the preeclampsia group, C2 levels correlated with urine total protein concentrations measured the same day (Spearman ρ = -0.49, P = 0.047, upper 95% CI -0.01) and with gestational age at first occurrence of hypertension (Spearman ρ = 0.59, P = 0.010, lower 95% CI 0.17). Among singleton gestations, C2 also correlated with newborn birth weight measured at delivery (Spearman ρ = 0.43, P = 0.009, lower 95% CI 0.11). Women who were hypertensive but aproteinuric at the time of compliance assessment, but who subsequently developed preeclampsia (n = 6), had C2 levels similar to those with an early diagnosis of preeclampsia (mean difference 0.37 mL/mm Hg · 100, 95% CI -2.42 to 1.67) and lower C2 levels than women diagnosed with gestational hypertension (P = 0.019, 95% CI 0.33-4.42 mL/mm Hg · 100). CONCLUSIONS: The noninvasive assessment of arterial elasticity may contribute toward characterization of the nature of the pathophysiology in pregnancy-induced hypertensive disorders. The vascular alterations of the small arteries, as assessed by C2, may reflect the extent of vascular alterations present with preeclampsia.
