Teaching residents the two-challenge rule: a simulation-based approach to improve education and patient safety.

Introduction: Residents train in a historically hierarchical system. They may be compelled to question their teachers if they do not understand or disagree with a clinical decision, have a patient safety concern, or when treatment plans are unclear. We sought to determine whether a debriefing intervention that emphasizes (1) joint responsibility for safety and (2) the “two-challenge rule” (a rubric for challenging others) using a conversational technique that is assertive and collaborative (advocacy-inquiry) can improve the frequency and effectiveness with which residents “speak up” to superiors. Methods: In a simulated operating room, anesthesiology trainees were presented with opportunities to challenge coworkers (eg, orders to administer a relatively contraindicated medication). Opportunities to challenge the attending faculty anesthesiologist, attending faculty surgeon, and nurse (all confederates) were presented. When debriefed, subjects were taught the two-challenge rule and a communication technique that paired advocacy (stating trainee’s observation) and inquiry (request for the other’s reasoning). A second scenario offered new opportunities to challenge. Video recorded scenarios were evaluated by two investigators and trainee use of the prescribed advocacy-inquiry language was rated on a 5-point scale. Results: Forty subjects participated. Overall use of the two-challenge rule and advocacy-inquiry increased after debriefing. The debriefing and instruction specifically improved the frequency and quality of challenges directed toward superordinate physicians, without improving resident challenges toward nurses. Conclusions: This instructional intervention improves “speaking up” by residents to other physicians during simulated obstetric cases. Providing increased opportunities for resident learning, sharing responsibility for patient safety, and overcoming communication barriers within the medical hierarchy may improve teamwork and patient safety.

Peripartum subarachnoid hemorrhage: nationwide data and institutional experience.

Background: Subarachnoid hemorrhage (SAH) in pregnancy occurs because of a variety of etiologies, which range from ruptured aneurysms to benign venous bleeding. The more malignant etiologies represent an important cause of maternal morbidity and mortality. We sought to investigate the epidemiology and mechanisms of pregnancy-related SAH. Methods: Using the Nationwide Inpatient Sample of the Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality, we extracted pregnancy-related admissions for women ages 15–44 from 1995–2008 and identified admissions complicated by SAH. Logistic regression identified independent predictors of SAH. Outcomes and risk factors were then compared with age-matched, nonpregnant women with SAH. We also analyzed our institutions experience with pregnancy-related SAH. Results: There were 639 cases (5.8 per 100,000 deliveries) of pregnancy-related SAH in the cohort during the study period; SAH was associated with 4.1% of all pregnancy-related in-hospital deaths. More than half of the SAH cases occurred postpartum. Advancing age, African-American race, Hispanic ethnicity, hypertensive disorders, coagulopathy, tobacco, drug or alcohol abuse, intracranial venous thrombosis, sickle cell disease, and hypercoagulability were independent risk factors for pregnancy-related SAH. Compared with SAH in nonpregnant controls, pregnancy-related SAH had lower clipping/coiling rates (12.7% vs. 44.5%, P < 0.001). We identified 12 cases of pregnancy-related SAH in our hospital, the majority of which presented postpartum and with severe headache. Conclusion: SAH during pregnancy results from a range of etiologies, and is less likely to be because of a cerebral aneurysm than SAH occurring in the nonpregnant patient. Peripartum SAH frequently occurs in the setting of hypertensive disorders.

Improving Anesthesiologists' Ability to Speak Up in the Operating Room: A Randomized Controlled Experiment of a Simulation-Based Intervention and a Qualitative Analysis of Hurdles and Enablers.

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.

Improving faculty feedback to resident trainees during a simulated case: a randomized, controlled trial of an educational intervention.

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.

Speaking across the drapes: communication strategies of anesthesiologists and obstetricians during a simulated maternal crisis.

Introduction Organizational behavior and management fields have long realized the importance of teamwork and team-building skills, but only recently has health care training focused on these critical elements. Communication styles and strategies are a common focus of team training but have not yet been consistently applied to medicine. We sought to determine whether such communication strategies, specifically “advocacy” and “inquiry,” were used de novo by medical professionals in a simulation-based teamwork and crisis resource management course. Explicit expression of a jointly managed clinical plan between providers, a strategy shown to improve patient safety, was also evaluated. Methods Forty-four of 54 videotaped performances of an ongoing team-building skills course were viewed and analyzed for presence of advocacy and/or inquiry that related to information or a plan; inclusion criteria were participation of a nonconfederate obstetrician and an anesthesiologist. Verbal statement of a jointly managed clinical plan was also recorded. Results Anesthesiologists advocated information in 100% of cases and advocated their plans in 93% of cases but inquired information in 30% of cases and inquired about the obstetricians’ plans in 11% of cases. Obstetricians advocated information in 73% of cases, advocated their plans in 73% of cases, inquired information in 75% of cases, and inquired about the anesthesiologists’ plans in 59% of cases. An explicitly stated joint team plan was formed in 45% of cases. Conclusions Anesthesiologists advocated more frequently than obstetricians, while obstetricians inquired and advocated in more balanced proportions. However, fewer than half of the teams explicitly agreed on a joint plan. Increasing awareness of communication styles, and possibly incorporating these skills into medical training, may help teams arrive more efficiently at jointly managed clinical plans in crisis situations.

Practicality of using galvanic skin response to measure intraoperative physiologic autonomic activation in operating room team members

BACKGROUND Physiologic and psychological stress are commonly experienced by operating room (OR) personnel, yet there is little research about the stress levels in OR teams and their impact on performance. Previously published procedures to measure physiologic activation are invasive and impractical for the OR. The purpose of this study was to determine the practicality of a new watch-sized device to measure galvanic skin response (GSR) in OR team members during high-fidelity surgical simulations. METHODS Interprofessional OR teams wore sensors on the wrist (all) and ankle (surgeons and scrub nurses/technicians) during the orientation, case, and debriefing phases for 17 simulations of a surgical airway case. Data were compared across all simulation phases, collectively and for each professional group. RESULTS Forty anesthesiology residents, 35 surgery residents, 27 OR nurses, 12 surgical technicians, and 7 CRNAs participated. Collectively, mean wrist GSR levels significantly increased from orientation phase to the case (0.40-0.62 μS; P < .001) and remained elevated even after the simulation was over (0.40-0.67 μS; P < .001). Surgery residents were the only group that demonstrated continued increases in wrist GSR levels throughout the entire simulation (change in GSR = 0.21 to 0.32 to 0.11 μS; P < .01). Large intraindividual differences (≤ 200 times) were found in both wrist and ankle GSR. There was no correlation between wrist and ankle data. CONCLUSION Continuous GSR monitoring of all professionals during OR simulations is feasible, but would be difficult to implement in an actual OR environment. Large variation in individual levels of physiologic activation suggests complementary qualitative research is needed to better understand how people respond to stressful OR situations.

Spontaneous coronary artery dissection in a parturient with Nail–Patella syndrome

Spontaneous coronary artery dissection is an uncommon cause of acute coronary syndrome, occurring predominantly in women during and immediately after pregnancy; it carries a mortality rate of greater than 50%. While the exact etiology is unknown, possible contributing factors include pregnancy-related hormonal, connective tissue and hemodynamic changes. We present a case of a 35-year-old multigravid woman with Nail-Patella syndrome who developed an acute myocardial infarction secondary to spontaneous coronary artery dissection during labor which was not diagnosed until after delivery. We hypothesize that abnormal collagen fiber formation found in Nail-Patella syndrome may have put her at an increased risk of coronary dissection and myocardial infarction. Regardless of etiology, a delay in diagnosis of myocardial ischemia can lead to significant morbidity and mortality. In light of the increasing burden of cardiac disease in the obstetric population, clinicians should remain vigilant for signs of myocardial infarction and prepare for definitive diagnosis and treatment.

Obstetric and Other Uses of Ether Before Ether Day, According to the Boston Medical and Surgical Journal of 1828-1846☆

From the inception of the Boston Medical and Surgical Journal in 1828 until the prominent public demonstration of surgical anesthesia on Ether Day of 1846, ether was often mentioned in the journal. Many of the examples were related to obstetrics. Because molecular structures were not available in the early 1800s, diverse volatile liquids were termed ethers. In addition to sulphuric ether, so-called ethers included cyanide-releasing propionitrile and ethanolic solutions of chloroform and of the potent vasodilator ethyl nitrite. Familiarity with anesthetically unsuitable ethers may have long deterred consideration of inhaled sulphuric ether for analgesia and anesthesia.

Third-degree heart block during spinal anesthesia for cesarean delivery.

A 34-year-old parturient developed third-degree atrioventricular block, in the setting of hypotension, after spinal anesthesia for cesarean delivery. The arrhythmia fully resolved with anticholinergic and sympathomimetic drugs. Considering the increasing maternal morbidity and potential risk of maternal cardiac arrest, this critical state is reviewed, and a treatment algorithm is suggested.

Board 400 - Research Abstract Integrating Technical and Team Training Skills in an In-Situ Simulation Operating Room (Submission #1193)

Introduction/Background Cricothyrotomy is an essential, life-saving procedure that is taught to our general surgery interns using task trainers. Unfortunately, the task trainers lack clinical context to know when to perform the procedure and how to work in the environment where the skill will be utilized. We hypothesized that practicing this skill in an in-situ operating room scenario fosters integration of technical and team-training skills for all participants. Methods Interprofessional teams (general surgery interns, anesthesiology residents and operating room nurses) were asked to manage a simulated intraoperative patient who progresses from a difficult intubation to a “cannot mask/cannot ventilate” situation requiring cricothyrotomy. Participants were then debriefed following the session. Results Four general surgery interns, eight anesthesia residents (PGY2-4) and eight OR nurses (5-30 years of experience) participated. Anesthesia residents notified the rest of the OR team about the possibility for cricothyrotomy in 25% of cases. A patent secured airway was not achieved in any cases and average time to attempted cricothyrotomy was late in 75% (>20 minutes of severe hypoxia) and early in 25% (patient not severely hypoxic). Fifty percent of nurses recognized the need and prepared for cricothyrotomy before requested but there was no physician-to-nurse communication prior to cricothyrotomy in any case. Ninety percent of participants agreed or strongly agreed that the simulation was realistic, clinically applicable and improved teamwork skills. The program also led to the discovery of real system issues such as variable contact information for the surgical airway team, unclear equipment locations and postcricothyrotomy management. Conclusion This in-situ operating room team-training program emphasized the utility of practicing cricothyrotomies in actual clinical environments and improved interdisciplinary communication. These programs may be a platform to develop and enhance intraoperative protocols or systems. Disclosures Gordon Center, University of Miami School of Medicine.
