Effect of Wearing a Face Mask on Hand-to-Face Contact by Children in a Simulated School Environment: The Back-to-School COVID-19 Simulation Randomized Clinical Trial.

Importance: Wearing a face mask in school can reduce SARS-CoV-2 transmission but it may also lead to increased hand-to-face contact, which in turn could increase infection risk through self-inoculation. Objective: To evaluate the effect of wearing a face mask on hand-to-face contact by children while at school. Design, Setting, and Participants: This prospective randomized clinical trial randomized students from junior kindergarten to grade 12 at 2 schools in Toronto, Ontario, Canada, during August 2020 in a 1:1 ratio to either a mask or control class during a 2-day school simulation. Classes were video recorded from 4 angles to accurately capture outcomes. Interventions: Participants in the mask arm were instructed to bring their own mask and wear it at all times. Students assigned to control classes were not required to mask at any time (grade 4 and lower) or in the classroom where physical distancing could be maintained (grade 5 and up). Main Outcomes and Measures: The primary outcome was the number of hand-to-face contacts per student per hour on day 2 of the simulation. Secondary outcomes included hand-to-mucosa contacts and hand-to-nonmucosa contacts. A mixed Poisson regression model was used to derive rate ratios (RRs), adjusted for age and sex with a random intercept for class with bootstrapped 95% CIs. Results: A total of 174 students underwent randomization and 171 students (mask group, 50.6% male; control group, 52.4% male) attended school on day 2. The rate of hand-to-face contacts did not differ significantly between the mask and the control groups (88.2 vs 88.7 events per student per hour; RR, 1.00; 95% CI, 0.78-1.28; P = >.99). When compared with the control group, the rate of hand-to-mucosa contacts was significantly lower in the mask group (RR, 0.12; 95% CI, 0.07-0.21), while the rate of hand-to-nonmucosa contacts was higher (RR, 1.40; 95% CI, 1.08-1.82). Conclusions and Relevance: In this clinical trial of simulated school attendance, hand-to-face contacts did not differ among students required to wear face masks vs students not required to wear face masks; however, hand-to-mucosa contracts were lower in the face mask group. This suggests that mask wearing is unlikely to increase infection risk through self-inoculation. Trial Registration: ClinicalTrials.gov Identifier: NCT04531254.

Genetic simulation for high-stakes conversations.

BACKGROUND: High-stakes conversations are frequent in Medical Genetics. News shared is often perceived as "bad" and can lead to patient hostility. Breaking bad news (BBN) is therefore a challenging clinical task for physicians and is often included as a foundational skill in medical education. The methods of teaching this skill are variable, with no widely accepted standard. We propose the use of simulation as a safe and effective training tool. APPROACH: Medical Genetics residents participated in a 4-week curriculum on BBN and de-escalating patient hostility and anger. The curriculum consisted of (1) a standardised patient simulation scenario requiring the disclosure of abnormal prenatal test result to a hostile patient, (2) coaching and feedback by genetic counsellors (GCs), (3) reflective exercises, and (4) workshops on de-escalation techniques. Trainees completed a postsimulation survey and postencounter reflection forms. Written comments on the survey and the reflections were analysed for themes. EVALUATION: Six junior and four senior residents participated in this curriculum innovation. Analysis of reflections revealed that simulation coupled with the genetic counsellor's (GC) timely feedback and reflection exercise were good education strategies for practicing BBN and de-escalation techniques in a challenging counselling situation. Most of the trainees felt that this teaching approach was successful and should be used for future training. IMPLICATIONS: Simulation can help prepare Medical Genetics trainees deliver difficult news and successfully de-escalate a hostile patient encounter. Consideration should be given to counselling and de-escalation simulations as a useful addition to standing curricula for Medical Genetics trainees.
