| Question | Summary of Responses and Identified Themes |
| Q1. What are your initial thoughts or impressions on the use of a barrier such as an acrylic box during intubation? | Cumbersome / restrictive (8 respondents) |
| Potentially / conditionally useful (6 respondents) | |
| Increased difficulty for intubation (3 respondents) | |
| Concerns of concentrated / lingering aerosol after removal (2 respondents) | |
| Concern of false sense of reassurance with use of box (1 respondent) | |
| Q2. Do you think you would use this in actual clinical practice? Why or why not? | Yes (1 respondent - if clinically indicated for a patient with airborne infection) |
| No (10 respondents) Reasons: | |
| - Increased intubation difficulty (4 respondents) | |
| - Aerosolization is a non-issue with proper paralysis (3 respondents) | |
| - Cumbersome design (3 respondents) | |
| - Low confidence in conferred protective benefits (2 respondents) | |
| Conditionally (4 respondents) | |
| - With more practice using the box (1 respondent) | |
| - If modified (1 respondent) | |
| - If more information supported efficacy (1 respondent) | |
| - For extubation when coughing is more prominent (1 respondent) | |
| Q3a. Do you think there are clinical scenarios in which these boxes or sheet barriers would be especially useful? | Yes - 10 respondents. Reasons: |
| - Extubation (5 respondents) | |
| - Active coughing (3 respondents) | |
| - Routine cases (2 respondents) | |
| - Cases with aerosol/droplet precautions (1 respondent) | |
| - Emergency with others in proximity (1 respondent) | |
| Did not comment (5 respondents) | |
| Q3b. Situations in which it would get in the way? | Yes (9 respondents) - Scenarios: |
| - Difficult/emergent airways (4 respondents) | |
| - Obese patients (2 respondents) | |
| - Remote cases (1 respondent) | |
| Did not comment (6 respondents) | |
| Q4. Did you feel use of the box hindered intubation performance? If so, how? | Yes (14 respondents) |
| - Restricted movement (7 respondents) | |
| - Difficulty pulling stylet due to box height (4 respondents) | |
| - Visibility hindered (2 respondents) | |
| - Distracting (1 respondent) | |
| - Unable to suction (1 respondent) | |
| - Concern for obese patients (1 respondent) | |
| No (1 respondent, who only noted "Easy to use in routine intubations.") | |
| Q5. What are improvements or changes you would suggest to the design or implementation of these barriers? | Provided suggestions - 12 respondents |
| - Modify box's size (8 respondents) | |
| - Modify accessibility (8 respondents) | |
| - Modify visibility (4 respondents) | |
| - Modify weight (3 respondents) | |
| - Alternate methodology: "Keep it simple. Use ppe for intubation, sheet or towel for extubation." (1 respondent) | |
| No suggestions (2 respondents) |
