Risk-adjusted rate of all-cause urgent readmission occurring within 30 days following discharge for an episode of care with an isolated coronary artery bypass graft surgery.

Number of hospitalisation episodes in the denominator with an urgent readmission within 30 days of discharge after the coronary artery bypass graft surgery index episode of care.

Number of hospitalisation episodes for patients age 18 and older who underwent an isolated coronary artery bypass graft surgery.

In-hospital death; Episodes with valve procedures; Episodes with core concomitant procedures.

Logistic regression. Covariates: Age, sex, urgent admission, previous acute myocardial infarction, cardiac dysrhythmias, hypertension, multiple cardiac interventions, peripheral vascular disease, acute renal failure, Charlson Index. The risk-adjusted rate for a facility is calculated by dividing the observed number of readmissions for each facility by the expected number of readmissions for the facility and multiplying by the Canadian average readmission rate.

CIHI Web Tool: Cardiac Care Quality Indicators Report. Belongs to a suite of Cardiac Care quality indicators (CCQI) that provided pan-Canadian comparable information on outcomes related to selected cardiac interventions. Publicly available indicator results are based on 3 years of pooled data. Results for 2018–2019 to 2020–2021 are the last that will be published for the CCQI indicators. No further updates after July 2022.
