mFI-5 Preoperative Frailty

mFI-5: A highly validated subset of the NSQIP database. A score of 2 or more indicates frailty and highly elevated surgical morbidity.

Select Present Factors

1. Diabetes Mellitus

History of diabetes requiring oral agents or insulin.

2. Hypertension

Hypertension requiring medication.

3. Congestive Heart Failure

History of CHF within 30 days prior to surgery.

4. COPD or Severe Pulmonary Disease

History of severe COPD, pneumonia, or recent ventilator dependency.

5. Non-Independent Functional Status

Partially or totally dependent in ADLs prior to illness/surgery.

When to Use

Preoperative risk stratification for older adults undergoing major surgery.

Predicting 30-day mortality, postoperative complications, and non-home discharge.

Used extensively across surgical specialties (orthopaedics, vascular, general, neurosurgery).

Database Derived

The mFI-5 was derived from the massive ACS-NSQIP database. It distills the complex 11-item and 70-item historical frailty indices down to the 5 most statistically powerful predictors of surgical morbidity, making it highly practical for the preoperative clinic.

Related Scores in Practice

In clinical practice, this assessment is frequently evaluated alongside other validated measures. Depending on the patient's presentation and specific diagnostic requirements, you may also need to utilize the Clinical Frailty Scale (CFS) or the Edmonton Frail Scale (EFS) to formulate a comprehensive care plan.
