Anesthesia myTIPreport: A Web-Based Tool for Real-Time Evaluation of Accreditation Council for Graduate Medical Education's Milestone Competencies and Clinical Feedback to Residents.

Feedback in clinical education is essential but challenged by multiple barriers. This report describes the use of myTIPreport, a web-based tool, which streamlines the dual purpose of milestone evaluation and real-time feedback from faculty to residents in a US anesthesiology program. In a 6-month trial, faculty members and residents used myTIPreport for daily clinical feedback. We believe myTIPreport will be a valuable tool for clinical feedback given further refinement of the tool and improved faculty and resident development on program use.

Utilization of the Flipped Classroom in Anesthesiology Graduate Medical Education: An Initial Survey of Faculty Beliefs and Practices About Active Learning.

BACKGROUND: Flipped classroom (FC) is an active learning (AL) technique thought to have potential benefits in anesthesiology resident education. This survey aimed to determine the frequency of FC utilization, barriers of utilization, and means to overcome these barriers. METHOD: A web-based questionnaire was developed to survey anesthesiology faculty on their knowledge of and experience with FC. The Society of Academic Associations of Anesthesiology and Perioperative Medicine sent the survey to all United States core program directors (PD) via their list serve with a request for the PDs to forward the survey invitation to their clinical faculty. Descriptive statistics were summarized. RESULTS: A total of 244 anesthesiology faculty completed the survey. Reported faculty understanding of AL and FC were 57%. Of these faculty, 87% utilized AL and 57% utilized FC in their personal teaching practice during the past year (spring 2015-spring 2016). The most prevalent barriers to utilization of FC were faculty concern that learners would not come to class prepared or participate in class, faculty comfort with delivering traditional lectures, lack of faculty knowledge of necessary technological tools, and faculty concern about perceived increase in time needed to create a FC session. Eighty-nine percent of all faculty desired education on FC with preference for institutional workshops or grand rounds. CONCLUSIONS: Our survey found a discrepancy between faculty knowledge of FC and usage of this method in anesthesiology resident teaching. More educational resources are warranted to address barriers and familiarize faculty with FC applications in anesthesiology resident education.

Validity of Simulation-Based Assessment for Accreditation Council for Graduate Medical Education Milestone Achievement.

INTRODUCTION: The Accreditation Council for Graduate Medical Education requires biannual evaluation of anesthesiology residents on 25 subcompetency milestones. Some milestone domains are particularly challenging to repeatedly and reliably observe during clinical care. Simulation-Based Milestones Assessment (SBMA) may help overcome these challenges. However, few studies have examined the external validation of simulation assessment scores (ie, the relationships between simulation-based assessment scores and other standard measures of ability) for milestones. This study analyzed whether SBMA scores (1) discriminate by postgraduate year, (2) improve over time, and (3) correlate with traditional measures of performance. METHODS: This is a retrospective analysis of 55 residents' SBMA data from 30 scenarios for two academic years. Each scenario was evaluated for time-in-training discrimination. Scenarios were then analyzed for SBMA scoring trends over time, and SBMA scores were compared with residents' clinical evaluations. RESULTS: Twenty-four SBMA scenarios discriminated by postgraduate year. Repeated measure analysis of variance showed statistically significant between-session score improvements (F (3, 54) = 17.79, P < 0.001). Pearson correlation coefficients demonstrated moderate to strong correlation between SBMA and clinical evaluations: January 2015 r = 0.67, P < 0.01 (n = 27); May 2015 r = 0.43, P = 0.09 (n = 17); November 2015 r = 0.70, P < 0.01 (n = 24); and April 2016 r = 70, P < 0.01 (n = 27). CONCLUSIONS: The associations between SBMA scores and experience level, time-in-training, and clinical performance evaluations provide evidence that SBMA may be used as metrics of residents' Accreditation Council for Graduate Medical Education milestone competencies.

Defining Value-Based Care in Cardiac and Vascular Anesthesiology: The Past, Present, and Future of Perioperative Cardiovascular Care.

Health care reimbursement models are transitioning from volume-based to value-based models. Value-based models focus on patient outcomes both during the hospital admission and postdischarge. These models place emphasis on cost, quality of care, and coordination of multidisciplinary services. Perioperative physicians are challenged to evaluate traditional practices to ensure coordinated, cost-effective, and evidence-based care. With the Centers for Medicare and Medicaid Services planned introduction of bundled payments for coronary artery bypass graft surgery, cardiovascular anesthesiologists are financially responsible for postdischarge outcomes. In order to meet these patient outcomes, multidisciplinary care pathways must be designed, implemented, and sustained, a process that is challenging at best. This review (1) provides a historical perspective of health care reimbursement; (2) defines value as it pertains to quality, service, and cost; (3) reviews the history of value-based care for cardiac surgery; (4) describes the drive toward optimization for vascular surgery patients; and (5) discusses how programs like Enhanced Recovery After Surgery assist with the delivery of value-based care.

Results of a Flipped Classroom Teaching Approach in Anesthesiology Residents.

BACKGROUND: In a flipped classroom approach, learners view educational content prior to class and engage in active learning during didactic sessions. OBJECTIVE: We hypothesized that a flipped classroom improves knowledge acquisition and retention for residents compared to traditional lecture, and that residents prefer this approach. METHODS: We completed 2 iterations of a study in 2014 and 2015. Institutions were assigned to either flipped classroom or traditional lecture for 4 weekly sessions. The flipped classroom consisted of reviewing a 15-minute video, followed by 45-minute in-class interactive sessions with audience response questions, think-pair-share questions, and case discussions. The traditional lecture approach consisted of a 55-minute lecture given by faculty with 5 minutes for questions. Residents completed 3 knowledge tests (pretest, posttest, and 4-month retention) and surveys of their perceptions of the didactic sessions. A linear mixed model was used to compare the effect of both formats on knowledge acquisition and retention. RESULTS: Of 182 eligible postgraduate year 2 anesthesiology residents, 155 (85%) participated in the entire intervention, and 142 (78%) completed all tests. The flipped classroom approach improved knowledge retention after 4 months (adjusted mean = 6%; P = .014; d = 0.56), and residents preferred the flipped classroom (pre = 46%; post = 82%; P < .001). CONCLUSIONS: The flipped classroom approach to didactic education resulted in a small improvement in knowledge retention and was preferred by anesthesiology residents.

A Descriptive Survey of Anesthesiology Residency Simulation Programs: How Are Programs Preparing Residents for the New American Board of Anesthesiology APPLIED Certification Examination?

BACKGROUND: Anesthesiology residency programs may need new simulation-based programs to prepare residents for the new Objective Structured Clinical Examination (OSCE) component of the American Board of Anesthesiology (ABA) Primary Certification process. The design of such programs may require significant resources, including faculty time, expertise, and funding, as are currently needed for structured oral examination (SOE) preparation. This survey analyzed the current state of US-based anesthesiology residency programs regarding simulation-based educational programming for SOE and OSCE preparation. METHODS: An online survey was distributed to every anesthesiology residency program director in the United States. The survey included 15 to 46 questions, depending on each respondent's answers. The survey queried current practices and future plans regarding resident preparation specifically for the ABA APPLIED examination, with emphasis on the OSCE. Descriptive statistics were summarized. χ and Fisher exact tests were used to test the differences in proportions across groups. Spearman rank correlation was used to examine the association between ordinal variables. RESULTS: The responding 66 programs (49%) were a representative sample of all anesthesiology residencies (N = 136) in terms of geographical location (χ P = .58). There was a low response rate from small programs that have 12 or fewer clinical anesthesia residents. Ninety-one percent (95% confidence interval [CI], 84%-95%) of responders agreed that it is the responsibility of the program to specifically prepare residents for primary certification, and most agreed that it is important to practice SOEs (94%; 95% CI, 88%-97%) and OSCEs (89%; 95% CI, 83%-94%). While 100% of respondents reported providing mock SOEs, only 31% (95% CI, 24%-40%) of respondents provided mock OSCE experiences. Of those without an OSCE program, 75% (95% CI, 64%-83%) reported plans to start one. The most common reasons for not having an OSCE program already in place, and the perceived challenges for implementing an OSCE program, were the same: lack of time (faculty and residents), expertise in OSCE development and assessment, and funding. CONCLUSIONS: The results provide data from residency programs for benchmarking their simulation curriculum and ABA APPLIED Examination preparation offerings. Despite agreement that residency programs should prepare residents for the ABA APPLIED Examination, many programs have yet to implement an OSCE preparation program, in part due to lack of financial resources, faculty expertise, and time. Additionally, in contrast to the SOE, the OSCE is a new format for ABA primary certification. As a result, the lack of consensus concerning preparation needs could be related to the amount information that is available regarding the examination content and assessment process.

The predictive value of pre-recruitment achievement on resident performance in anesthesiology.

STUDY OBJECTIVE: Selecting candidates for residency positions is challenging and there is little research on the correlation between commonly used selection criteria and subsequent performance in anesthesiology. This study examined the association between the selection measures and post-recruitment performance in residency. DESIGN: Retrospective review of archival data. SETTING: Anesthesiology residency program at a large academic anesthesiology department. SUBJECTS: Residents who were matched to the anesthesiology program over 9years (graduation classes of 2006 to 2014). INTERVENTIONS: None. MEASUREMENTS: The pre-recruitment achievements included a comprehensive list of measures obtained from residents' application portfolios in conjunction with interview performance. The post-recruitment examination outcomes consisted of the in-training examination (ITE) scores in the three clinical anesthesia (CA) years and first-attempt success on the written board certification examination administered by the American Board of Anesthesiology (ABA). Scholarly output during residency was measured by publication record. Clinical performance at the conclusion of residency was independently rated by three faculty members. Bivariate analysis and regression models were conducted to examine association between predictors and outcomes. MAIN RESULTS: High United States Medical Licensing Examination (USMLE) scores, class rank in medical school and interview performance were predictive of high examination scores in residency and good clinical performance. Class rank appeared to be the best predictor of scholarly publication and pursuing an academic career beyond residency. CONCLUSIONS: Comparative performance with classmates (i.e., class rank) in medical school appeared to be an effective predictor of overall performance in residency, which warrants more attention in future study. Although interview performance is subject to recruitment team members' interpretation, it is an important measure to include in recruitment decisions.

BMI as a Predictor for Potential Difficult Tracheal Intubation in Males.

INTRODUCTION: Difficult tracheal intubation is a common source of mortality and morbidity in surgical and critical care settings. The incidence reported of difficult tracheal intubation is 0.1%-13% and reaches 14% in the obese population. The objective of our retrospective study was to investigate and compare the utility of body mass index (BMI) as indicator of difficult tracheal intubation in males and females. MATERIAL AND METHODS: We performed a retrospective chart review of patients who underwent abdominal surgeries with American Society of Anesthesiologists I to V under general anesthesia requiring endotracheal intubation. The following information was obtained from medical records for analysis: gender, age, height, weight, BMI, length of patient stay in the Post Anesthesia Care Unit, past medical history of sleep apnea, Mallampati score, and the American Society of Anesthesiologists classification assigned by the anesthesia care provider performing the endotracheal intubation. RESULTS: Of 4303 adult patients, 1970 (45.8%) men and 2333 (54.2%) women were enrolled in the study. Within this group, a total of 1673 (38.9%) patients were morbidly obese. The average age of the study group was 51.4 ± 15.8 and the average BMI was 29.7 ± 8.2 kg/m(2). The overall incidence of the encountered difficult intubations was 5.23% or 225 subjects. Thus, our results indicate that BMI is a reliable predictor of difficult tracheal intubation predominantly in the male population; another strong predictor, with a positive linear correlation, being the Mallampati score. CONCLUSION: In conclusion, our data shows that BMI is a reliable indicator of potential difficult tracheal intubation only in male surgical patients.

Simulator training enhances resident performance in transesophageal echocardiography.

BACKGROUND: Standardized training via simulation as an educational adjunct may lead to a more rapid and complete skill achievement. The authors hypothesized that simulation training will also enhance performance in transesophageal echocardiography image acquisition among anesthesia residents. METHODS: A total of 42 clinical anesthesia residents were randomized to one of two groups: a control group, which received traditional didactic training, and a simulator group, whose training used a transesophageal echocardiography-mannequin simulator. Each participating resident was directed to obtain 10 commonly used standard views on an anesthetized patient under attending supervision. Each of the 10 selected echocardiographic views were evaluated on a grading scale of 0 to 10, according to predetermined criteria. The effect of the intervention was assessed by using a linear mixed model implemented in SAS 9.3 (SAS Institute Inc., Cary, NC). RESULTS: Residents in the simulation group obtained significantly higher-quality images with a mean total image quality score of 83 (95% CI, 74 to 92) versus the control group score of 67 (95% CI, 58 to 76); P = 0.016. On average, 71% (95% CI, 58 to 85) of images acquired by each resident in the simulator group were acceptable for clinical use compared with 48% (95% CI, 35 to 62) in the control; P = 0.021. Additionally, the mean difference in score between training groups was the greatest for the clinical anesthesia-1 residents (difference 24; P = 0.031; n = 7 per group) and for those with no previous transesophageal echocardiography experience (difference 26; P = 0.005; simulator n = 13; control n = 11). CONCLUSION: Simulation-based transesophageal echocardiography education enhances image acquisition skills in anesthesiology residents.

A Novel Core Competencies-Based Academic Medicine Curriculum: Description and Preliminary Results.

BACKGROUND: Physicians practice health care in a rapidly changing system that requires more than the delivery of safe and effective care. Modern physicians must also acquire skills beyond direct patient care. Residency programs must, therefore, prepare physicians to meet these demands by providing appropriate education and training. METHODS: We designed, implemented and assessed an academic medicine curriculum in the first post-graduate year. This curriculum provides comprehensive exposure to necessary non-patient contact related physician skills. Topics centered around four domains: critical appraisal of literature of literature, quality improvement, professional development, and teaching. Each of these domains is linked to the six core competencies established by the Accreditation Council for Graduate Medical Education's (ACGME). Instruction includes small-group learning sessions with additional time for self-directed online modules and a faculty-mentored quality improvement research project that is presented at a graduation symposium. All residents completed a survey evaluation of the curriculum before and after the course via open-ended questions and Likert responses (0-5). We assessed improvement in resident confidence with each curricular domain using mean Likert score change and 95% confidence intervals (CI). RESULTS: Residents improved at all curricular domains measured. The most significant mean changes included confidence in: poster presentations (2.7; 95% CI: 1.9-3.5), plan-do-check-act cycle (2.5; 95% CI: 2.1-2.9), quality improvement projects (2.4; 95% CI: 1.9-2.9), and abstract presentation (2.3; 95% CI: 1.6-3.0). CONCLUSIONS: We found that the academic medicine rotation (AMR) is feasible in a large academic setting. Furthermore, the AMR allows early exposure to and improvement in essential non-patient contact related physician skills required by the ACGME core competencies and assessed through the milestones.

Enhancement of anesthesiology in-training exam performance with institution of an academic improvement policy.

BACKGROUND: Anesthesiology resident physicians across the United States complete an annual in-training examination (ITE). The ITE evaluates resident knowledge and provides personalized feedback to guide future study in low scoring sections(1). Performance on the ITE correlates with outcomes on the American Board of Anesthesiology (ABA) written board examination(2). Over the last several years, declining ITE scores were observed at the University of North Carolina (UNC). In response to this decline, our department reprioritized the ITE by instituting an academic improvement policy (AIP). The AIP employed both reward for satisfactory achievement and consequence for under-performance to elevate the ITE as a "high stakes" examination. Our hypothesis was that implementation of this AIP would improve ITE scores. METHODS: ITE scores were compiled from 150 residents in the Department of Anesthesiology at UNC for graduating classes from 2004-2015. Data is presented as the number of residents scoring below the 20th percentile when compared to the national distribution before and after the AIP. In addition, average USMLE Step 1 three-digit scores for each graduating class were compared to average ITE percentile scores of the corresponding graduating class (USMLE does not provide percentile scores). RESULTS: Between 2009 and 2013, the number of residents who scored below the 20th percentile on the ITE increased steadily to a peak of 10 in 2011. After implementation of the AIP in July 2011, there was an 80% decrease in those scoring below the 20th percentile, from 10 to 2 residents (p<0.05). CONCLUSIONS: Anesthesiology resident ITE scores improved after implementation of an academic improvement policy.

Inhibition of phosphodiesterases leads to prevention of the mitochondrial permeability transition pore opening and reperfusion injury in cardiac H9c2 cells.

PURPOSE: We tested if inhibition of phosphodiesterases (PDEs) with IBMX (1-methyl-3-isobutylxanthine) can modulate the mitochondrial permeability transition pore (mPTP) opening by inactivating glycogen synthase kinase 3ß (GSK-3ß). METHODS: H9c2 cells were exposed to 600 µM H(2)O(2) for 20 min to cause the mPTP opening. Mitochondrial membrane potential (ΔΨm) was assessed by imaging cells loaded with tetramethylrhodamine ethyl ester (TMRE). Cell viability was measured with propidium iodide (PI) fluorometry using a fluorescence reader. Ischemia/reperfusion injury was induced by exposing cells to ischemic solution for 90 min followed by 30 min of reperfusion. RESULTS: IBMX reduced loss of ΔΨm caused by H(2)O(2), indicating that inhibition of PDEs can prevent the mPTP opening. However, IBMX could not inhibit the pore opening in cells transfected with the constitutively active GSK-3ß (GSK-3ß-S9A) mutant, suggesting a critical role of GSK-3ß in the action of IBMX. IBMX also reduced reperfusion injury in a GSK-3ß dependent manner. In support, IBMX increased GSK-3ß phosphorylation at Ser(9), an effect that was reversed by both the PKA inhibitor H89 and the PKG inhibitor KT5823. In support, IBMX activated both PKA and PKG. IBMX failed to prevent the loss of ΔΨm in the presence of H89 or PKA siRNA. Similarly, both KT5823 and PKG siRNA reversed the protective effect of IBMX. CONCLUSION: Inhibition of PDEs prevents the mPTP opening by inactivating GSK-3ß through PKA and PKG. GSK-3ß is a common downstream target of PKA and PKG. Inhibition of PDEs may be a useful approach to prevent reperfusion injury.

Prognostic value of tissue Doppler-Derived E/e' on early morbid events after cardiac surgery.

BACKGROUND: The tissue Doppler-derived surrogate for left ventricular diastolic pressure, E/e', has been used to prognosticate outcome in a variety of cardiovascular conditions. In this study, we determined the relationship of intraoperative E/e' to the use of inotropic support, duration of mechanical ventilation (MV), length of intensive care unit stay (ICU-LOS), and total hospital stay (H-LOS) in patients requiring cardiac surgery. The records of 245 consecutive patients were retrospectively reviewed to obtain 205 patients who had intraoperative transesophageal echocardiography examinations prior to coronary artery bypass grafting and/or valvular surgery. Cox proportional hazards and logistic regression models were used to analyze the relation between intraoperative E/e' or LVEF and early postoperative morbidity (H-LOS, ICU-LOS, and MV) and the probability that a patient would require inotropic support. With adjustments for other predictors (female gender, hypertension, diabetes, history of myocardial infarction, emergency surgery, renal failure, procedure type, and length of aortic cross-clamp time), an elevated E/e' ratio (>or=8) was significantly associated with an increased ICU-LOS (49 versus 41 median h, P = 0.037) and need for inotropic support (P = 0.002) while baseline LVEF was associated with inotropic support alone (P < 0.0001). These data suggest that the tissue Doppler-derived index of left ventricular diastolic filling pressure may be a useful indicator for predicting early morbid events after cardiac surgery, and may even provide additional information from that of baseline LVEF. Further, patients with elevated preoperative E/e' may need more careful peri- and postoperative management than those patients with E/e' <8.

The critical role of intracellular zinc in adenosine A(2) receptor activation induced cardioprotection against reperfusion injury.

Exogenous zinc can protect cardiac cells from reperfusion injury, but the exact roles of endogenous zinc in the pathogenesis of reperfusion injury and in adenosine A(2) receptor activation-induced cardioprotection against reperfusion injury remain unknown. Adenosine A(1)/A(2) receptor agonist 5'-(N-ethylcarboxamido) adenosine (NECA) given at reperfusion reduced infarct size in isolated rat hearts subjected to 30min ischemia followed by 2h of reperfusion. This effect of NECA was partially but significantly blocked by the zinc chelator N,N,N',N'-tetrakis-(2-pyridylmethyl) ethylenediamine (TPEN), and ZnCl(2) given at reperfusion mimicked the effect of NECA by reducing infarct size. Total tissue zinc concentrations measured with inductively coupled plasma optical emission spectroscopy (ICPOES) were decreased upon reperfusion in rat hearts and this was reversed by NECA. NECA increased intracellular free zinc during reperfusion in the heart. Confocal imaging study showed a rapid increase in intracellular free zinc in isolated rat cardiomyocytes treated with NECA. Further experiments revealed that NECA increased total zinc levels upon reperfusion in mitochondria isolated from isolated hearts. NECA attenuated mitochondrial swelling upon reperfusion in isolated hearts and this was inhibited by TPEN. Similarly, NECA prevented the loss of mitochondrial membrane potential (DeltaPsim) caused by oxidant stress in cardiomyocytes. Finally, both NECA and ZnCl(2) inhibited the mitochondrial metabolic activity. NECA-induced cardioprotection against reperfusion injury is mediated by intracellular zinc. NECA prevents reperfusion-induced zinc loss and relocates zinc to mitochondria. The inhibitory effects of zinc on both the mPTP opening and the mitochondrial metabolic activity may account for the cardioprotective effect of NECA.

Adenosine A2A and A2B receptors work in concert to induce a strong protection against reperfusion injury in rat hearts.

We aimed to test if stimulation of both adenosine A2A and A2B receptors is required to produce an effective cardioprotection against reperfusion injury. Isolated rat hearts were subjected to 30-min regional ischemia followed by 2 h of reperfusion. The adenosine A1/A2 receptor agonist 5'-(N-ethylcarboxamido) adenosine (NECA) given at reperfusion reduced infarct size, an effect that was reversed by both the adenosine A2A antagonist SCH58261 and the A2B antagonist MRS1706. The A2B agonist BAY 60-6583 but not the selective A2A agonist CGS21680 reduced infarct size. Interestingly, a combination of BAY 60-6583 and CGS21680 further reduced infarct size. These results suggest that both A2A and A2B receptors are involved in NECA's anti-infarct effect at reperfusion. NECA attenuated mitochondrial swelling upon reperfusion and this was blocked by both SCH58261 and MRS1706, indicating that activation of A2 receptors with NECA can modulate reperfusion-induced mitochondrial permeability transition pore (mPTP) opening. In support, NECA also prevented oxidant-induced loss of mitochondrial membrane potential (DeltaPsi(m)) and matrix Ca2+ overload in cardiomyocytes via both the A2 receptors. In addition, NECA increased mitochondrial glycogen synthase kinase-3beta (GSK-3beta) phosphorylation upon reperfusion and this was again blocked by SCH58261 and MRS1706. In conclusion, A2A and A2B receptors work in concert to prevent reperfusion injury in rat hearts treated with NECA. NECA may protect the heart by modulating the mPTP opening through inactivating mitochondrial GSK-3beta. A simultaneous stimulation of A2A and A2B receptors at reperfusion is required to produce a strong cardioprotection against reperfusion injury.
