  • Preclinical curriculum of prospective case-based teaching with faculty- and student-blinded approach. BMC medical education Waliany, S., Caceres, W., Merrell, S. B., Thadaney, S., Johnstone, N., Osterberg, L. 2019; 19 (1): 31

    Abstract

    BACKGROUND: Case-based teaching with real patient cases provides benefit of simulating real-world cognition. However, while clinical practice involves a prospective approach to cases, preclinical instruction typically involves full disclosure of case content to faculty, introducing hindsight bias into faculty teaching in medical curricula.METHODS: During 2015-2018, we piloted an optional medical school curriculum involving 6-7 one-hour sessions over a 3-month period each year. New groups enrolled each year from first- and second-year classes. A facilitator provided a blinded physician discussant and blinded students with case information during and not in advance of each session, allowing prospective case-based discussions. Cases were based on real patients treated in the Department of Medicine. Clinical material was presented in the chronologic sequence encountered by treating physicians. Content covered a median of 5 patient visits/case (range: 2-10) spanning over months. A 14-item survey addressing components of the reporter-interpreter-manager-educator (RIME) scheme was developed and used to compare self-reported clinical skills between course participants and non-participant controls during the 2016 course iteration.RESULTS: This elective curriculum at Stanford School of Medicine involved 170 preclinical students (22.7% of 750 eligible). During the 2016 course iteration, a quasi-experimental study compared self-reported clinical skills between 29 course participants (response rate: 29/49 [59.2%]) and 35 non-participant controls (response rate: 35/132 [26.5%]); students self-assessed clinical skills via the RIME-based survey developed for the course. Two-sample t-tests compared the change in pre- and post-course skills between course participants and non-participants. Of 15 Department of Medicine faculty members invited as discussants, 12 (80%) consented to participate. Compared with controls, first-year participants self-assessed significantly greater improvement in understanding how clinicians reason through cases step-by-step to arrive at diagnoses (P=0.049), work through cases in longitudinal settings (P=0.049), and share information with patients (P=0.047). Compared with controls, second-year participants self-assessed significantly greater improvement (P=0.040) in understanding how clinicians reason through cases step-by-step to arrive at diagnoses.CONCLUSIONS: Prospective case-based discussions with blinding offaculty and students to clinical content circumvents hindsight bias and may impart real-world cognitive skills as determined by student self-report.

  • Immersion medicine programme for secondary students. The clinical teacher Minhas, P. S., Kim, N., Myers, J., Caceres, W., Martin, M., Singh, B. 2017

    Abstract

    Although the proportion of ethnicities representing under-represented minorities in medicine (URM) in the general population has significantly increased, URM enrolment in medical schools within the USA has remained stagnant in recent years.This study sought to examine the effect of an immersion in community medicine (ICM) programme on secondary school students' desire to enter the field of medicine and serve their communities. The authors asked all 69 ICM alumni to complete a 14-question survey consisting of six demographic, four programme and four career questions, rated on a Likert scale of 1 (completely disagree) to 5 (completely agree), coupled with optional free-text questions. Data were analysed using GraphPad prism and nvivo software.A total of 61 students responded, representing a response rate of 88.4 per cent, with a majority of respondents (73.7%) from URM backgrounds. An overwhelming majority of students agreed (with a Likert rating of 4 or 5) that the ICM programme increased their interest in becoming a physician (n = 56, 91.8%). Students reported shadowing patient-student-physician interactions to be the most useful (n = 60, 98.4%), and indicated that they felt that they would be more likely to lead to serving the local community as part of their future careers (n = 52, 85.3%). Of the students that were eligible to apply to medical school (n = 13), a majority (n = 11, 84.6%) have applied to medical school. URM enrolment in medical schools within the USA has remained stagnant in recent years DISCUSSION: Use of a community medicine immersion programme may help encourage secondary students from URM backgrounds to gain the confidence to pursue a career in medicine and serve their communities. Further examination of these programmes may yield novel insights into recruiting URM students to medicine.

  • Hand hygiene of medical students and resident physicians: predictors of attitudes and behaviour. Postgraduate medical journal Barroso, V., Caceres, W., Loftus, P., Evans, K. H., Shieh, L. 2016; 92 (1091): 497-500

    Abstract

    We measured medical students' and resident trainees' hand hygiene behaviour, knowledge and attitudes in order to identify important predictors of hand hygiene behaviour in this population.An anonymous, web-based questionnaire was distributed to medical students and residents at Stanford University School of Medicine in August of 2012. The questionnaire included questions regarding participants' behaviour, knowledge, attitude and experiences about hand hygiene. Behaviour, knowledge and attitude indices were scaled from 0 to 1, with 1 representing superior responses. Using multivariate regression, we identified positive and negative predictors of superior hand hygiene behaviour. We investigated effectiveness of interventions, barriers and comfort reminding others.280 participants (111 students and 169 residents) completed the questionnaire (response rate 27.8%). Residents and medical students reported hand hygiene behaviour compliance of 0.45 and 0.55, respectively (p=0.02). Resident and medical student knowledge was 0.80 and 0.73, respectively (p=0.001). The attitude index for residents was 0.56 and 0.55 for medical students. Regression analysis identified experiences as predictors of hand hygiene behaviour (both positive and negative influence). Knowledge was not a significant predictor of behaviour, but a working gel dispenser and observing attending physicians with good hand hygiene practices were reported by both groups as the most effective strategy in influencing trainees.Medical students and residents have similar attitudes about hand hygiene, but differ in their level of knowledge and compliance. Concerns about hierarchy may have a significant negative impact on hand hygiene advocacy.
