The Medical Student Guide to Pharmacy: Piloting an Interactive Textbook on Basic Pharmacology Principles and Clinical Correlations.

OBJECTIVES: Despite the wide use of medications in clinical practice, graduating medical students often feel unprepared for the task of prescribing upon starting residency. With recent educational initiatives aiming to transform learning modalities, we sought to pilot an interactive textbook on basic pharmacology principles at our institution as a supplement to first-year lectures and assess its subjective impact on students' knowledge of content as well as confidence to apply material in the real world through pre- and post-intervention surveys. METHODS: First-year medical students were invited to complete non-validated, voluntary, anonymous, emailed, online surveys consisting of Likert scale and free-text response questions. Our investigation served as a pilot test for future iterations of this research. RESULTS: Response rates for the pre- and post-intervention surveys were 73/145 (50%) and 38/145 (26%), respectively, with the post-intervention survey further reduced to 13 individuals who indicated use of the interactive textbook. Questions regarding interactive textbook chapters that overlapped with course content were excluded from data analysis due to an inability to separate learning gains from lectures versus the interactive textbook. Post-intervention survey responses all showed significant changes in mean Likert scale scores on student-perceived knowledge and confidence to apply material with P < .001. Free-text response questions revealed limited exposure to the field of pharmacy and interactions with pharmacists prior to medical school. CONCLUSION: Our pilot study on the initial use of an interactive textbook titled The Medical Student Guide to Pharmacy presented us with valuable insight into providing first-year medical students with a clinically oriented supplemental resource within coursework on basic pharmacology. Challenges for the future include better integrating the interactive textbook into class lectures to facilitate increased use by students as well as developing more targeted, validated assessments of the impact it has on students' learning.

Impact of a Preclinical Medical Student Anesthesiology Elective on the Attitudes and Perceptions of Medical Students Regarding Anesthesiology.

Purpose: First- and second-year medical students typically have limited exposure to the field of anesthesiology, yet recent match data shows growing interest in the specialty. Early, structured exposure to anesthesiology in the form of a preclinical elective may allow medical students to make more informed decisions on their specialty of choice. Methods: The anesthesiology preclinical elective, BIOL 6704: "Anesthesia: Much More than Putting you to Sleep", is a one-credit course taught at The Warren Alpert Medical School of Brown University. A survey consisting of fifteen questions assessing changes in attitudes, perceptions, and interest in anesthesiology was distributed to first- and second-year medical students before and after course participation. The results were analyzed using the Wilcoxon's signed-rank test for paired samples. Results: The biggest impact of the preclinical elective was observed in the students' subjective understanding of key aspects of the practice of anesthesiology. Statistically significant improvement was seen in the understanding of airway management, anesthetic pharmacology, basics of ultrasound, vascular access, anesthesiology subspecialties, and an understanding of anesthesiology residency. Overall, results were limited by our small sample size. Conclusion: Our elective allows medical students to explore anesthesiology early in their medical school career. After taking this course, students noted more familiarity with various topics in anesthesiology. Peer institutions lacking a similar course may consider using our experience to increase interest about the specialty of anesthesiology for future students.

Echocardiographic imaging of a bifurcated double barrel coronary sinus.

BACKGROUND: The coronary sinus (CS) is the terminal collecting vessel of the myocardial venous network, which returns deoxygenated blood used by the heart to the right atrium. The advent of high-fidelity imaging via CT and transesophageal echocardiography (TEE) has further defined the anatomy of the CS and its multiple tributaries. Understanding this anatomy is crucial for cardiac surgical cases that require the cannulation of the coronary sinus to deliver retrograde cardioplegia. However, anatomical variants of the CS may frustrate surgical retrograde catheter placement, in turn increasing the risk of CS injury or leading to inadequate cardioplegia delivery. Here, we present an especially unique CS presentation, a bifurcated, double-barrel CS, which was discovered via intraoperative TEE imaging that revealed a CS with two smaller lumens instead of the singular large os. CASE PRESENTATION: A 67-year-old male presented for ascending aortic dissection repair, aortic valve replacement, and single vessel coronary artery bypass graft. On the pre-bypass TEE exam, the anesthesiologist noted a bifurcated CS with two small lumens. The surgeon utilized this information to select a smaller diameter retrograde catheter to avoid damage or perforation of the vessel. With TEE guidance, the surgeon successfully cannulated one of the CS lumens. However, it was noted upon dosing of retrograde cardioplegia that all tributary vessels attached to the non-cannulated lumen remained devoid of cardioplegia. The surgeon was forced to repeatedly administer anterograde cardioplegia via a handheld catheter through the coronary ostium throughout the case. The operative field was also flooded with topical ice saline slush to ensure cardiac protection. Ultimately, the operation was completed without incident despite the non-ideal conditions resulting from this anatomic variant. CONCLUSIONS: Discovery of this patient's double-barrel CS during the pre-bypass TEE was incidental, showing that such anatomical variants may be completely asymptomatic and benign in the non-operative setting. However, the delivery of cardioplegia proved challenging for this patient, highlighting some degree of risk with certain cardiac interventions. This case demonstrates the utility of intraoperative TEE to quickly ascertain unforeseen anatomical variants of the CS which could compromise the safety of cardiac surgery cases.
