Percentage of patients whose cardiac surgery or procedure was completed within target time
Percentage of patients who underwent a cardiac surgery or procedure within the provincial access target
measures the percentage of patients that require a cardiac surgery or procedure
and receive it within the provincial access target. Wait times were calculated
from the day the patient and doctor decided to go ahead with the surgery or
procedure, to the day it was performed. A higher percentage is better. The
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:
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.
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.
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.

Caveats and Limitations
1. This indicator is collected for patients who have undergone this procedure. That is, patients who are still waiting are not included in the calculation.
2. This indicator is reported not at the surgeon level but rather at the level of the facility where the procedure took place.
3. Cardiac service hospital with small volumes will be more severely impacted by extreme waits (particularly the average wait time). For example, an unusually long or short wait time for a single patient in a reporting period for hospitals will have a greater impact on the average.
4. Certain components of wait times may be difficult to capture. For example, the “decision to treat” date data element has a less standardized definition which may be open to some interpretation.
