Definition
The Discharge Function Score calculates the percent of IRF patients who achieve a riskx0002adjusted expected function score at discharge.
Numerator
Number of IRF stays with an observed discharge function score that is equal to or greater than the calculated expected discharge function score
Denominator
Total number of IRF stays with an IRF-PAI record in the measure target period, which do not meet the exclusion criteria
Exclusions
Denominator Exclusions: The IRF stay is excluded if any of the following are true: • Patient has an incomplete stay. Patients with incomplete stays include patients who are discharged to an acute care setting (Short-stay Acute Hospital, Critical Access Hospital, Inpatient Psychiatric Facility, or Long-term Care Hospital) for longer than 3 calendar days; patients who die or leave an Inpatient Rehabilitation Facility (IRF) against medical advice; and patients with a length of stay less than three days. • Patient is in a coma, persistent vegetative state, or locked-in state, or has complete tetraplegia, severe anoxic brain damage, cerebral oedema, or compression of brain. • Patient is younger than 18 years: Age in years is calculated based on the truncated difference between admission date and birth date, i.e., the difference is not rounded to the nearest whole number. • Patient is discharged to hospice (home or institutional facility).
Use of Risk Adjustment
Risk Adjustments
Risk-adjusting the observed discharge function score for each IRF stay with controls for patient characteristics such as admission function score, age, and clinical conditions
