Risk-adjusted rate of all-cause urgent readmission occurring within 30 days following discharge for an episode of care with a percutaneous coronary intervention.

Number of hospitalisation episodes within the denominator with a non-elective readmission within 30 days of discharge after the percutaneous coronary intervention index episode of care.

Number of hospitalisation episodes for patients age 18 and older who underwent a percutaneous coronary intervention.

In-hospital death.

Logistic regression. Covariates: Age, sex, cerebrovascular disease, peripheral vascular disease, coronary syndrome status, shock, cardiac dysrhythmias, multiple cardiac interventions, previous acute myocardial infarction, previous cardiac interventions, multivessel PCI, acute renal failure, Charlson Index, acute care transfer. 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.
