INDICATOR DESCRIPTION

Description

This indicator measures the total number of patients that underwent a cardiac surgery or procedure. This indicator is reported by priority level. Patients are assigned a priority level for the surgery based on their clinical assessment. The indicator is reported based on the institution where the surgery took place.

There are three cardiac surgeries or procedures reported Online:

1.A diagnostic cardiac catheterization (CATH), or angiography, is a catheter based diagnostic test that involves selectively injecting x-ray contrast dye into one or more coronary arteries in order to visualize blockages in the arteries and vessels that supply blood to the heart.

2.A percutaneous coronary intervention (PCI), or angioplasty, is a procedure that involves using a catheter to insert a stent that opens blocked blood vessels in the coronary arteries.

3.Coronary artery bypass graft (CABG) is a surgical procedure performed on patients with coronary artery disease to bypass areas of blockage. Blood vessels, most commonly from the legs or chest wall, are grafted onto the heart to allow blood to flow past diseased heart vessels.

Numerator including inclusion/exclusion

All adult cardiac surgeries or procedures that are done in the reporting period within Ontario's 19 advanced cardiac service hospitals and meet the inclusion criteria below:

Inclusions:

1.Static (month-end) Data.

2.Must be onlisted and offlisted as that procedure: Onlisted and offlisted refers to being put on the waiting list. Once a patient sees a specialist (cardiologist, cardiac surgeon) and that physician accepts the patient for a procedure (CATH, PCI, CABG) they are "onlisted" to the wait list. Once the patient receives their treatment and the procedure is over the patient is "offlisted" from the wait list (because the treatment is done).

3.Wait time takes into account DART* per patient.

*DART stands for Dates Affecting Readiness to Treat. It means that a wait list clock is paused because the patient asked the physician to pause it.There is no limit to the number of DARTS that can be applied to a surgery. If a patient changes priority, the wait time clock is restarted against the target for the new priority.

Exclusions:

1.Patients who die before they receive their procedures
