    A Simulation-based PPE orientation training curriculum for novice physicians
    (Elsevier, 2023) Greaves, Spencer W.; Alter, Scott M.; Ahmed, Rami A.; Hughes, Kate E.; Doos, Devin; Clayton, Lisa M.; Solano, Joshua J.; Echeverri, Sindiana; Shih, Richard D.; Hughes, Patrick G.; Emergency Medicine, School of Medicine
    Background: Personal protective equipment (PPE) is effective in preventing coronavirus disease (COVID-19) infection. Resident knowledge of proper use and effective training methods is unknown. We hypothesise that contamination decreases and knowledge increases after a formalised PPE educational session. Methods: Participants included first year interns during their residency orientation in June 2020. Before training, participants took a knowledge test, donned PPE, performed a simulated resuscitation, and doffed. A standardised simulation-based PPE training of the donning and doffing protocol was conducted, and the process repeated. Topical non-toxic highlighter tracing fluid was applied to manikins prior to each simulation. After doffing, areas of contamination, defined as discrete fluorescent areas on participants' body, was evaluated by ultraviolet light. Donning and doffing were video recorded and asynchronously rated by two emergency medicine (EM) physicians using a modified Centers for Disease Control and Prevention (CDC) protocol. The primary outcome was PPE training effectiveness defined by contamination and adherence to CDC sequence. Results: Forty-eight residents participated: 24 internal medicine, 12 general surgery, 6 EM, 3 neurology, and 3 psychiatry. Before training, 81% of residents were contaminated after doffing; 17% were contaminated after training (P<0.001). The most common contamination area was the wrist (50% pre-training vs. 10% post-training, P<0.001). Donning sequence adherence improved (52% vs. 98%, P<0.001), as did doffing (46% vs. 85%, P<0.001). Participant knowledge improved (62%-87%, P <0.001). Participant confidence (P<0.001) and preparedness (P<0.001) regarding using PPE increased with training. Conclusion: A simulation-based training improved resident knowledge and performance using PPE.

    How to HEEAL: A Patient and Peer-Centric Simulation Curriculum for Medical Error Disclosure
    (AAMC, 2024-04-02) Falvo, Lauren; Bona, Anna; Heniff, Melanie; Cooper, Dylan; Moore, Malia; Doos, Devin; Sarmiento, Elisa; Hobgood, Cherri; Ahmed, Rami; Emergency Medicine, School of Medicine
    Introduction: Medical errors are an unfortunate certainty with emotional and psychological consequences for patients and health care providers. No standardized medical curriculum on how to disclose medical errors to patients or peers exists. The novel HEEAL (honesty/empathy/education/apology-awareness/lessen chance for future errors) curriculum addresses this gap in medical education through a multimodality workshop. Methods: This 6-hour, two-part curriculum incorporated didactic and standardized patient (SP) simulation education with rapid cycle deliberate practice (RCDP). The morning focused on provider-patient error disclosure; the afternoon applied the same principles to provider-provider (peer) discussion. Summative simulations with SPs evaluated learners' skill baseline and improvement. Formative simulations run by expert simulation educators used RCDP to provide real-time feedback and opportunities for adjustment. Medical knowledge was measured through pre- and postintervention multiple-choice questions. Learners' confidence and attitude towards medical errors disclosure were surveyed pre- and postintervention with assistance of the Barriers to Error Disclosure Assessment tool, revised with the addition of several questions related to provider-provider disclosure. Results: Fourteen medical students participated in this pilot curriculum. Statistical significance was demonstrated in medical knowledge (p = .01), peer-disclosure skills (p = .001), and confidence in medical error disclosure (p < .001). Although there was improvement in patient-disclosure skills, this did not reach statistical significance (p = .05). Discussion: This curriculum addresses the need for designated training in medical error disclosure. Learners gained knowledge, skills, and confidence in medical error disclosure. We recommend this curriculum for medical students preparing for transition to residency.

    Reuse of Personal Protective Equipment: Results of a Human Factors Study Using Fluorescence to Identify Self-Contamination During Donning and Doffing
    (Elsevier, 2022) Doos, Devin; Barach, Paul; Sarmiento, Elisa; Ahmed, Rami; Emergency Medicine, School of Medicine
    Background: At least 115,000 health and care workers (HCWs) are estimated to have lost their lives to COVID-19, according to the the chief of the World Health Organization (WHO). Personal protective equipment (PPE) is the first line of defense for HCWs against infectious diseases. At the height of the pandemic, PPE supplies became scarce, necessitating reuse, which increased the occupational COVID-19 risks to HCWs. Currently, there are few robust studies addressing PPE reuse and practice variability, leaving HCWs vulnerable to accidental contamination and harm. Objective: The objective of this study was to assess potential HCW contamination during PPE donning, doffing, and reuse. Methods: The study included 28 active acute care physicians, nurses, and nurse practitioners that evaluated 5 simulated patients with COVID-like symptoms while donning and doffing PPE between each patient encounter. An N95 mask was contaminated with a transparent fluorescent gel applied to the outside of the N95 mask to simulate contamination that might occur during reuse. Participants were evaluated after PPE doffing for each encounter using a black light to assess for face and body contamination. Results: All participants had multiple sites of contamination, predominantly on their head and neck. None of the participants were able to don and doff PPE without contaminating themselves during five consecutive simulation cycles. Conclusions: The current Centers for Disease Control and Prevention PPE guidelines for donning and doffing fall short in protecting HCWs. They do not adequately protect HCWs from contamination. There is an urgent need for PPE and workflow redesign.
