The effect of supplemental high Fidelity simulation training in medical students.

BACKGROUND: Simulation-based education (SBE) with high-fidelity simulation (HFS) offers medical students early exposure to the clinical environment, allowing development of clinical scenarios and management. We hypothesized that supplementation of standard pulmonary physiology curriculum with HFS would improve the performance of first-year medical students on written tests of pulmonary physiology. METHODS: This observational pilot study included SBE with three HFS scenarios of patient care that highlighted basic pulmonary physiology. First-year medical students' test scores of their cardio-pulmonary curriculum were compared between students who participated in SBE versus only lecture-based education (LBE). A survey was administered to the SBE group to assess their perception of the HFS. RESULTS: From a class of 188 first-year medical students, 89 (47%) participated in the SBE and the remaining 99 were considered as the LBE group. On their cardio-pulmonary curriculum test, the SBE group had a median score of 106 [IQR: 97,110] and LBE group of 99 [IQR: 89,105] (p < 0.001). For the pulmonary physiology subsection, scores were also significantly different between groups (p < 0.001). CONCLUSIONS: Implementation of supplemental SBE could be an adequate technique to improve learning enhancement and overall satisfaction in preclinical medical students.

Perioperative do-not-resuscitate orders: Trainee experiential learning in preserving patient autonomy and knowledge of professional guidelines.

ABSTRACT: Anesthesiologists and surgeons have demonstrated a lack of familiarity with professional guidelines when providing care for surgical patients with a do-not-resuscitate (DNR) order. This substantially infringes on patient's self-autonomy; therefore, leading to substandard care particularly for palliative surgical procedures. The interventional nature of surgical procedures may create a different mentality of surgical "buy-in," that may unintentionally prioritize survivability over maintaining patient self-autonomy. While previous literature has demonstrated gains in communication skills with simulation training, no specific educational curriculum has been proposed to specifically address perioperative code status discussions. We designed a simulated standardized patient actor (SPA) encounter at the beginning of post-graduate year (PGY) 2, corresponding to the initiation of anesthesiology specific training, allowing residents to focus on the perioperative discussion in relation to the SPA's DNR order.Forty four anesthesiology residents volunteered to participate in the study. PGY-2 group (n = 17) completed an immediate post-intervention assessment, while PGY-3 group (n = 13) completed the assessment approximately 1 year after the educational initiative to ascertain retention. PGY-4 residents (n = 14) did not undergo any specific educational intervention on the topic, but were given the same assessment. The assessment consisted of an anonymized survey that examined familiarity with professional guidelines and hospital policies in relation to perioperative DNR orders. Subsequently, survey responses were compared between classes.Study participants that had not participated in the educational intervention reported a lack of prior formalized instruction on caring for intraoperative DNR patients. Second and third year residents outperformed senior residents in being aware of the professional guidelines that detail perioperative code status decision-making (47%, 62% vs 21%, P = .004). PGY-3 residents outperformed PGY-4 residents in correctly identifying a commonly held misconception that institutional policies allow for automatic perioperative DNR suspensions (85% vs 43%; P = .02). Residents from the PGY-3 class, who were 1 year removed the educational intervention while gaining 1 additional year of clinical anesthesiology training, consistently outperformed more senior residents who never received the intervention.Our training model for code-status training with anesthesiology residents showed significant gains. The best results were achieved when combining clinical experience with focused educational training.

Early experience with a combined surgical and obstetrics/gynecology clerkship: We do get along.

BACKGROUND: In 2012, the Ohio State University College of Medicine (OSUCOM) implemented a new undergraduate medical curriculum. We compare outcomes of a third year traditional clerkship format to a combined Surgery and Obstetrics/Gynecology 'ring'. METHODS: Performance outcomes of 4 consecutive classes were compared between pre- (2014, 2015) and post-curricular revision (2016, 2017). RESULTS: Three hundred ninety-one students consented use of their educational data for research. We examined medical knowledge (NBME scores, USMLE Step 1 and Step 2 CK scores) and student satisfaction between pre- and post-curricular revision. Results demonstrated no statistically significant difference in the Obstetrics/Gynecology NBME shelf examination. Surgery NBME and USMLE Step 2 scores were increased and statistically significant but satisfaction of both disciplines was higher pre-curricular revision. CONCLUSION: Medical knowledge outcomes in this combined 'ring' were similar to or higher than performance in previous years'. Future analyses are needed to assess the impact of OSUCOM curricular revision.

Physiologically Triggered Digital Cognitive Aid Facilitates Crisis Management in a Simulated Operating Room: A Randomized Controlled Study.

INTRODUCTION: Although the benefits of using cognitive aids in anesthesia care have previously been demonstrated, several challenges remain. It must be presented in a timely manner, and providers must be amenable to using the tool once it is available. We hypothesized that anesthesia residents would perform superiorly when presented with a digital cognitive aid (DCogA) that is automatically triggered by a set vital sign aberration. METHODS: Thirty anesthesia residents were randomized to either control (with access to hard copy of the cognitive aid) or receive a DCogA projected on their anesthesia information management system with the onset of heart block and associated hypotension. The scenario ended upon commencement of pacing, and the times to interventions were recorded. RESULTS: Fourteen participants were randomized to the control group and 16 to the intervention group DCogA. In the control group, 6 of 14 participants failed to pace, and in the DCogA group, all participants initiated pacing (P < 0.01). Those in the DCogA group were also faster to pace [260.1 (137.5) s vs. 405.1 (201.8) s, P = 0.03]. Both groups were similar with respect to their knowledge of advanced cardiovascular life support as measured by a pretest (P = 0.92). CONCLUSIONS: We found those participants who were presented with electronic, physiologically triggered cognitive aids were more likely to appropriately treat heart block by initiating transcutaneous pacing. We believe that adoption of a high-functioning anesthesia information management system designed to detect physiologic perturbations and present appropriate decision support tools would lead to safer intraoperative care.

Relationship between chest lateral width, tube current, image noise, and radiation exposure associated with coronary artery calcium scanning on 320-detector row CT.

BACKGROUND: The relationship between chest lateral width, tube current, image noise, and radiation exposure on 320-detector row CT has not been reported. OBJECTIVE: We investigated the relationships between chest lateral width, estimated radiation exposure (DLPe), and image noise in 300 patients undergoing clinical coronary calcium scanning. METHODS: Patients undergoing coronary calcium scanning with 320-detector row CT (prospective, volumetric mode, 120 kV of tube voltage, 100-550 mA of tube current, 0.5-mm detector width) were grouped by chest lateral width (small, medium, and large) from anteroposterior topograms and 100 consecutive patients were selected from each group (n = 300). Tube current, DLPe, and noise were compared among groups with Kruskal-Wallis or one-way ANOVA. Phantom experiments were performed to evaluate the accuracy of calcium quantification as a function of size and tube current. RESULTS: Median tube current in small, medium, and large patients was 130, 200, and 250 mA, respectively (P < 0.0001). Despite the use of higher tube current settings, noise levels also increased with size (20.2 ± 4.5 HU, 22.0 ± 3.9 HU, and 25.1 ± 4.9 HU, respectively; global P < 0.001). DLPe was significantly higher with increasing size (54, 83, and 104 mGy · cm, respectively; P < 0.0001). Phantom experiments showed that 50-100 mA, 150-200 mA, and approximately 300 mA in small, medium, and large phantoms were associated with stable estimate of calcium. CONCLUSIONS: Increasing chest lateral width is associated with increasing radiation exposure and image noise. The use of 50-100 mA in small and 150-200 mA in medium patients is associated with acceptable noise and stable estimate of coronary artery calcium. In large patients, precise identification of individual calcified lesions remains difficult despite increasing tube current and radiation exposure.
