Modified 11-Item Frailty Index (mFI-11)
Modified Frailty Index-11 (Velanovich 2013): an 11-item accumulated-deficit fraction; a higher fraction tracks rising postoperative morbidity and mortality.

Example
- Diabetes mellitus
- Yes
- Congestive heart failure
- Yes
- Myocardial infarction
- Yes
Result: mFI-11 deficits 3/11 (index 27.3%): a higher accumulated-deficit fraction tracks rising postoperative risk.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Deficits
- diabetes, dependent status, COPD/pneumonia, CHF, MI, cardiac intervention/angina, hypertension, PVD/rest pain, impaired sensorium, TIA/CVA, CVA with deficit — one each, count/11.
- Use
- the original accumulated-deficit index; a higher fraction tracks rising postoperative morbidity and mortality. The validated 5-item mFI-5 performs comparably.
What you enter
- Diabetes mellitus
- Dependent functional status
- COPD or current pneumonia
- Congestive heart failure
- Myocardial infarction
- Prior PCI, cardiac surgery, or angina
- Hypertension requiring medication
- Peripheral vascular disease or rest pain
The other 3 fields
- Impaired sensorium
- TIA or cerebrovascular accident
- CVA with neurological deficit
