Hospital-level, 30-day risk-standardised readmission rate for patients discharged from the hospital with either a principal discharge diagnosis of Chronic Obstructive Pulmonary Disease (COPD) or a principal discharge diagnosis of acute respiratory failure with a secondary discharge diagnosis of COPD with exacerbation.

30-day, all-cause readmissions for patients discharged from the hospital with either a principal discharge diagnosis of COPD or a principal discharge diagnosis of acute respiratory failure with a secondary discharge diagnosis of COPD with exacerbation. This measure looks for a dichotomous yes or no outcome of whether each admitted patient has an unplanned readmission within 30 days.

Admissions for patients that meet all of the following inclusion criteria: 1. Discharged from the hospital with either a principal discharge diagnosis of COPD or a principal discharge diagnosis of acute respiratory failure with a secondary discharge diagnosis of COPD with exacerbation; 2. Aged 65 or over; 3. Discharged alive; 4. Not transferred to another acute care facility.

Index admissions: 1. Without at least 30 days of post-discharge enrolment in Medicare fee-for-service; 2. COPD admissions within 30 days of discharge from a prior COPD index admission; 3. Discharged against medical advice; 4. With a principal diagnosis/secondary diagnosis code of COVID-19 coded as present on admission on the index admission claim.

Hierarchical logistic regression is used to adjust for differences in hospital case mix (age and clinical status of the patient, accounted for by adjusting for comorbidities) and to account for the clustering of patients within a hospital. The measure calculates a risk-standardised ratio of the number of predicted readmissions to the number of expected readmissions. This ratio is multiplied by the national observed readmission rate to get the risk-standardised readmission rate (RSRR).
