Mini-Z — Physician Burnout Assessment Scale
What Mini-Z Is
The Mini-Z is a brief, validated self-assessment tool for measuring physician burnout. Originally developed by the American Medical Association (AMA) and the Mayo Clinic, it is one of the most widely used single-item burnout measures in healthcare research and quality improvement.
The standard Mini-Z asks physicians a single question:
“Using your own definition of burnout, how would you rate your level of burnout?”
Respondents answer on a 5-point scale:
- I enjoy my work. I have no symptoms of burnout.
- I am under stress, and I don’t always have resources to cope, but I don’t feel burned out.
- I am burning out. I have one or more symptoms of burnout (e.g., emotional exhaustion, depersonalization).
- I feel burned out and wonder if I should be in healthcare.
- I am so burned out I need to seek help.
A score of 3 or higher is typically used as the threshold for “burnout” in research studies.
Mini-Z in the Abridge Research
The Olson et al. JAMA Network Open study used Mini-Z as the primary burnout measurement instrument:
- Pre-implementation burnout rate: 51.9% (Mini-Z ≥3)
- 30-day post-implementation burnout rate: 38.8% (Mini-Z ≥3)
- Adjusted odds ratio: 0.26 (95% CI 0.13–0.54, P<.001)
The Mini-Z is paired with a longer 10-item burnout scale in the Olson study to create a composite burnout assessment.
Why Mini-Z Is Important for AI Scribe Research
Burnout is the primary clinical outcome that Abridge’s research team targets — not time savings, not revenue, not documentation quality. Burnout reduction is the clinically meaningful outcome that drives purchasing decisions by health system CMIOs and wellness officers.
Mini-Z is particularly useful because:
- It’s one question — easy to add to a pre/post survey
- It’s validated against longer instruments
- It’s widely used — allows benchmarking across institutions
- It’s directionally sensitive — can detect change over short periods (30 days)
