Introduction to Tobacco Cessation and Motivational Interviewing: Evaluation of a Lecture and Case-Based Learning Activity for Medical Students.

Introduction Despite the fact that tobacco use continues to have significant public health impacts, most healthcare providers are not adequately trained to counsel patients on their tobacco use or to provide cessation resources. Although all healthcare providers have a role in providing tobacco cessation assistance, physicians and advanced practice providers are generally the only practitioners able to furnish tobacco cessation medications and bill insurance for their cessation services. Therefore, ensuring these practitioners are properly trained to offer tobacco cessation to their patients is critical to addressing this public health threat. In line with this goal, this study outlines the curriculum evaluation for an innovative student-facilitated tobacco cessation activity for medical students. Methods A lecture and case-based learning activity was created and piloted with a class of first-year medical students. The activity was facilitated by fourth-year medical students. Students took a pre-session survey to establish baseline experience and beliefs and a post-session survey to ascertain their confidence in applying what was covered in the session. Descriptive statistics were utilized to analyze the data. Results One hundred and twenty-eight students completed both surveys. Prior to the activity, students reported low levels of confidence in their ability to counsel patients and knowledge of cessation resources. Following the activity, more than 90% reported improvement in their ability to assess a patient's willingness to quit and counsel those ready to quit. Greater than 80% reported an improvement in their ability to counsel patients not ready to quit and to establish a quit plan. More than 90% of students reported that the session increased their self-efficacy in helping patients quit and that it was worth their time, with 96% committing to increasing their tobacco cessation efforts with their patients. Discussion Students valued the training and almost all reported that it increased their ability to help patients quit smoking. The use of student-facilitated case-based learning provided both an opportunity for students to practice cessation techniques and a low-stakes introduction to the OSCE format without the need for extensive faculty resources. Although this session was run with first-year medical students, the curriculum presented can be used for residents, nurses, and other healthcare professionals.

Comparing the Perceptions of Reciprocal- and Near-Peer Objective Structured Clinical Examinations (OSCEs) in Medical Students.

INTRODUCTION: The Objective Structured Clinical Examination (OSCE) is utilized by medical schools to assess students' competency in clinical skills. Literature has shown that first-year students who were tutored by fourth-year students (MS4s; near-peer) in practice OSCEs reported self-perceived improvement in OSCE skills. There is a lack of research regarding the effectiveness of first-year (MS1) pairs for reciprocal-peer practice OSCEs. This study aims to assess if virtual reciprocal-peer OSCEs provide comparable learning opportunities to virtual near-peer OSCEs. METHODS: MS1 students were assigned to work with a near-peer or a reciprocal-peer for one week, and then switched protocols the second week. One student in each reciprocal-peer pair was assigned to act as a standardized patient (SP). Their partner took a history, interpreted physical exam findings, prepared a note, and gave an oral presentation. The pair then switched roles using a second case. The near-peer group followed the same procedure, without the reversal of roles. RESULTS: A total of 135 MS1s participated in the first week and 129 in the second week. Students agreed that working with a near-peer was more valuable than a reciprocal-peer in the following parameters: peer feedback (N=113, 89%), history-taking skills (N=101, 80%), physical exam skills (N=102, 81%), and note-writing skills (N=109, 89%). Pairwise comparison utilizing Wilcoxon signed-rank test indicated participants preferred the choice of a fourth-year student partner over an MS1 partner (Z=1.436, p<0.001). CONCLUSION: Participants found working with a near-peer increased confidence in their clinical skills and near-peer feedback was more valuable. Although MS1s found that watching and evaluating their peers in a reciprocal-peer exercise was beneficial, students overwhelmingly preferred working with MS4s due to more valuable feedback.

Clostridioides difficile Infection: Update on Management.

Guidelines for the diagnosis and treatment of Clostridioides difficile infection have recently been updated. Risk factors include recent exposure to health care facilities or antibiotics, especially clindamycin. C. difficile infection is characterized by a wide range of symptoms, from mild or moderate diarrhea to severe disease with pseudomembranous colitis, colonic ileus, toxic megacolon, sepsis, or death. C. difficile infection should be considered in patients who are not taking laxatives and have three or more episodes of unexplained, unformed stools in 24 hours. Testing in these patients should start with enzyme immunoassays for glutamate dehydrogenase and toxins A and B or nucleic acid amplification testing. In children older than 12 months, testing is recommended only for those with prolonged diarrhea and risk factors. Treatment depends on whether the episode is an initial vs. recurrent infection and on the severity of the infection based on white blood cell count, serum creatinine level, and other clinical signs and symptoms. For an initial episode of nonsevere C. difficile infection, oral vancomycin or oral fidaxomicin is recommended. Metronidazole is no longer recommended as first-line therapy for adults. Fecal microbiota transplantation is a reasonable treatment option with high cure rates in patients who have had multiple recurrent episodes and have received appropriate antibiotic therapy for at least three of the episodes. Good antibiotic stewardship is a key strategy to decrease rates of C. difficile infection. In routine or endemic settings, hands should be cleaned with either soap and water or an alcohol-based product, but during outbreaks soap and water is superior. The Infectious Diseases Society of America does not recommend the use of probiotics for prevention of C. difficile infection.

Favorable results from the 2 studies reviewed here have prompted ACOG to recommend that cell-free DNA screening be discussed with all pregnant patients.
