Does Realism Matter? A Randomized Controlled Trial Comparing Models for Medical Student Suture Education.

ABSTRACT: Background:We hypothesized that medical students trained in suturing using high-fidelity models (cadaveric tissue) would demonstrate greater proficiency when compared with those trained using low-fidelity models (synthetic tissue). Methods:Forty-three medical students were randomized into 2 groups. Group 1 consisted of students taught to perform simple interrupted sutures using synthetic tissue, and group 2 consisted of those taught using human cadaveric tissue. Suturing proficiency was measured pre- and postinstruction using the Global Rating Scale and by measuring suture accuracy. Perceived confidence in suturing was measured on a scale of 0-100. Results:Perceived confidence was measured as an average of 8.26 out of 100 pretraining and significantly improved after training (56.91 out of 100); however, there was no significant difference when comparing confidence between groups posttraining (57.65 cadaveric versus 56.05 synthetic; P = 0.78), nor in the measured confidence change pre- and posttraining (P = 0.53). Posttraining, participants displayed a significant improvement in the number of adequately placed sutures; however, there was no significant difference posttraining when comparing groups (2.43 cadaveric versus 2.75 synthetic; P = 0.48). The change in adequate suture placement pre- and posttraining did not reach statistical significance between groups (P = 0.27). After instruction, participants demonstrated a significant improvement in total suture performance scores; however, there was no significant difference when comparing groups (30.04 cadaveric versus 29.80 synthetic; P = 0.90), nor in the total change pre- and posttraining (P = 0.74). Conclusions:Training medium fidelity (tissue versus synthetic) does not significantly influence a student's overall suturing performance. However, formal instruction significantly improves objective competence and perceived confidence. Regardless of the model, surgical departments should emphasize medical student exposure to basic surgical skills education.

Project description:BACKGROUND:More than 8.5 million Germans suffer from chronic diseases attributable to smoking. Education Against Tobacco (EAT) is a multinational network of medical students who volunteer for school-based prevention in the classroom setting, amongst other activities. EAT has been implemented in 28 medical schools in Germany and is present in 13 additional countries around the globe. A recent quasi-experimental study showed significant short-term smoking cessation effects on 11-to-15-year-old adolescents. OBJECTIVE:The aim of this study was to provide the first randomized long-term evaluation of the optimized 2014 EAT curriculum involving a photoaging software for its effectiveness in reducing the smoking prevalence among 11-to-15-year-old pupils in German secondary schools. METHODS:A randomized controlled trial was undertaken with 1504 adolescents from 9 German secondary schools, aged 11-15 years in grades 6-8, of which 718 (47.74%) were identifiable for the prospective sample at the 12-month follow-up. The experimental study design included measurements at baseline (t1), 6 months (t2), and 12 months postintervention (t3), via questionnaire. The study groups consisted of 40 randomized classes that received the standardized EAT intervention (two medical student-led interactive modules taking 120 minutes total) and 34 control classes within the same schools (no intervention). The primary endpoint was the difference in smoking prevalence from t1 to t3 in the control group versus the difference from t1 to t3 in the intervention group. The differences in smoking behavior (smoking onset, quitting) between the two groups, as well as gender-specific effects, were studied as secondary outcomes. RESULTS:None of the effects were significant due to a high loss-to-follow-up effect (52.26%, 786/1504). From baseline to the two follow-up time points, the prevalence of smoking increased from 3.1% to 5.2% to 7.2% in the control group and from 3.0% to 5.4% to 5.8% in the intervention group (number needed to treat [NNT]=68). Notable differences were observed between the groups for the female gender (4.2% to 9.5% for control vs 4.0% to 5.2% for intervention; NNT=24 for females vs NNT=207 for males), low educational background (7.3% to 12% for control vs 6.1% to 8.7% for intervention; NNT=30), and migrational background (students who claimed that at least one parent was not born in Germany) at the 12-month follow-up. The intervention appears to prevent smoking onset (NNT=63) but does not appear to initiate quitting. CONCLUSIONS:The intervention appears to prevent smoking, especially in females and students with a low educational background.

Project description:IntroductionGood handoffs require teamwork, clear communication, a cognitively safe environment, and a good understanding of the patient's medical needs. Complex tertiary care training institutions require multiple handoffs over a patient's time in the hospital. Medical students need better handoff education. We designed a handoff training exercise using a simulated patient care environment for students to practice and observe multiple handoffs over time.MethodsAn initial large-group didactic session provides direct instruction on handoffs. In small groups, students are subsequently assigned roles as individual physicians in a chain of providers during a simulated patient hospitalization over several days, with an additional student as an observer. Blinded to any prior discussion, student physicians sequentially give and receive handoffs about the patient from a previous physician as their simulated hospital course evolves. The observer shares his or her insights, and a large-group structured debriefing exercise follows.ResultsIn both 2015 and 2016, we implemented this session with a cohort of 30 fourth-year medical students. Most recently we implemented this with chief residents, and a group of 20 third-year pediatric clerkship students. We reviewed a selection of the discussion guides and found reporters/ observers noted that participants stated the primary problem 95% of the time (19 of 20 handoffs), the patient acuity 90% of the time (18 of 20 handoffs), and a clear contingency plan 85% of the time (17 of 20 handoffs).DiscussionWe found students initially to be preoccupied with making correct clinical decisions instead of giving effective handoffs, and consequently we clarified details and adjusted clinical information to be more transparent. Results suggest the session achieves our goals of using a structured handoff method to communicate higher-level information and debrief effectively with peers. We envision this activity to be applicable to teaching handoffs to residents, nurses, and other health care professionals, as well as possibly in diverse clinical environments or in collaboration with outpatient providers.

Project description:The emergency medicine (EM) clerkship curriculum at Los Angeles County + University of Southern California Medical Center includes monthly lectures on pediatric fever and shortness of breath (SOB). This educational innovation evaluated if learning could be enhanced by "priming" the students with educational online videos prior to an in-class session. Factors that impacted completion rates were also evaluated (planned specialty and time given for video viewing).Twenty-minute videos were to be viewed prior to the didactic session. Students were assigned to either the fever or SOB group and received links to those respective videos. All participating students took a pre-test prior to viewing the online lectures. For analysis, test scores were placed into concordant groups (test results on fever questions in the group assigned the fever video and test results on SOB questions in the group assigned the SOB video) and discordant groups (crossover between video assigned and topic tested). Each subject contributed one set of concordant results and one set of discordant results. Descriptive statistics were performed with the Mann-Whitney U test. Lecture links were distributed to students two weeks prior to the in-class session for seven months and three days prior to the in-class session for eight months (in which both groups included both EM-bound and non-EM bound students).In the fifteen-month study period, 64% of students rotating through the EM elective prepared for the in class session by watching the videos. During ten months where exclusively EM-bound students were rotating (n=144), 71.5% of students viewed the lectures. In four months where students were not EM-bound (n=54), 55.6% of students viewed the lectures (p=0.033). Participation was 60.2% when lecture links were given three days in advance and 68.7% when links were given two weeks in advance (p=0.197). In the analysis of concordant scores, the pre-test averaged 56.7% correct, the immediate post-test averaged 78.1% correct, and the delayed post-test was 67.2%. In the discordant groups, the pretest averaged 51.9%, the immediate posttest was 67.1% and the delayed by 68.8%. In the concordant groups, the immediate post-test scores improved by 21.4%, compared with 15.2% in the discordant groups (p = 0.655). In the delayed post-test the concordant scores improved by 10.5% and discordant scores by 16.9 percent (p=0.609). Sixty-two percent of students surveyed preferred the format of online videos with in-class case discussion to a traditional lecture format.Immediate post-tests and delayed post-tests improved but priming was not demonstrated to be a statistically superior educational method in this study. Medical student completion of the preparatory materials for the EM rotation session increased when the students were EM-bound. Participation rates were not significantly different when given at two weeks versus three days.

Project description:BackgroundDuring the Covid-19 pandemic medical students were offered paid roles as medical student healthcare assistants. Anecdotal reports suggested that students found this experience rich for learning. Previous studies have explored alternative models of student service, however this defined medical student support role is novel.MethodsIndividual semi-structured interviews were recorded with 20 medical students at a UK medical school exploring their experiences of placement learning and experiences of working as healthcare assistants. Responses were analysed qualitatively using a framework approach. The framework was developed into a model describing key findings and their relationships.ResultsInterviews yielded data that broadly covered aspects of (1) Medical students' experiences of clinical placement learning (2) Medical students' experiences of working as medical student healthcare assistants (3) Learning resulting from working as a healthcare assistant (4) Hierarchies and professional barriers in the clinical environment (5) Influences on professional identity. Participants described barriers and facilitators of clinical learning and how assuming a healthcare assistant role impacted on learning and socialisation within the multidisciplinary team. Students became increasingly socialised within the healthcare team, contributing directly to patient care; the resulting social capital opened new opportunities for learning, team working and enhanced students' interprofessional identity. Students described the impact of these experiences on their aspirations for their future practice.ConclusionsChanges to work patterns in healthcare and delivery models of medical education have eroded opportunities for students to contribute to healthcare delivery and be embedded within a team. This is impacting negatively on student learning and socialisation and we suggest that medical curricula have much to learn from nursing and allied health professional training. Longitudinal embedment with a multidisciplinary team, where students have a defined role and work directly with patients may not only add value to clinical service, but also overcome current barriers to effective placement learning and interprofessional identity formation for medical students.
