Table 2. Burnout inventory scores.

Question: Overall, based on your definition of burnout, how would you rate your level of burnout? Response options:  1. I enjoy my work. I have no symptoms of burnout.  2. Occasionally I am under stress, and I don't always have as much energy as I once did, but I don't feel burned out.  3. I am definitely burning out and have one or more symptoms of burnout, such as physical and emotional exhaustion.  4. The symptoms of burnout that I'm experiencing won't go away. I think about frustration at work a lot.  5. I feel completely burned out and often wonder if I can go on. I am at the point where I may need some changes or may need to seek some sort of help
Resident type	Residents burned out, number (%)
New night float resident, n  = 4	0 (0%)
Traditional call system resident, n  = 11	6 (54.5%)

Comparing resident perceptions of burnout between the new night float system to the traditional call system. Presence of burnout was defined as choosing a level of 3–5 on the single-item questionnaire. NOTE: Two residents in the new night float system were excluded from the questionnaire because they are investigators of this study (SA and AG).
