The risk-standardised readmission rate for Medicare Fee-for-Service (FFS) beneficiaries aged 65 or older who were hospitalised and experienced an unplanned readmission for any cause to a short-stay acute-care hospital within 30 days of discharge.

Any unplanned readmission to a non-federal, short-stay, acute-care or critical access hospital within 30 days of discharge from an index admission.

Eligible index admissions include acute care hospitalisations for FFS beneficiaries aged 65 or older at non-federal, short-stay, acute-care or critical access hospitals that were discharged during the performance period.

Hospitalisations are generally excluded from the denominator if the beneficiary was: • Discharged against medical advice • Hospitalised in a prospective payment system-exempt cancer hospital • Hospitalised primarily for medical treatment of cancer • Hospitalised primarily for a psychiatric disease • Hospitalised for "rehabilitation care or fitting of prostheses and adjustment devices" (CCS 254) • Was not able to be attributed to a clinician group • Not continuously enrolled in Medicare Part A FFS for at least 12 months prior to the index admission and 30 days following discharge from the index admission; or • With a principal or a secondary diagnosis code of COVID-19 coded as present on admission (POA) on the index admission claim.

Five specialty cohort models adjust for case mix differences among providers by risk adjusting for patients' comorbid conditions identified in inpatient episodes of care for the 12 months prior to the index admission as well as those present at admission.
