We invited 62 anesthesiologists to participate, of whom 24 did not respond, 5 declined, 3 responded affirmatively but did not respond to subsequent scheduling requests, and 30 (48%) agreed and were interviewed. The interviews were conducted from August 2020 to June 2021. One interview was not completed because the interviewee experienced an interruption; this interview was excluded from the study. The mean interview length was 52 min.
