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:

  1. I enjoy my work. I have no symptoms of burnout.
  2. I am under stress, and I don’t always have resources to cope, but I don’t feel burned out.
  3. I am burning out. I have one or more symptoms of burnout (e.g., emotional exhaustion, depersonalization).
  4. I feel burned out and wonder if I should be in healthcare.
  5. 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)
