Readmission rate for percutaneous coronary intervention (PCI)

Why is this measure important?

Percutaneous coronary intervention (PCI), commonly known as angioplasty, is used to treat patients with diseased (narrowed or blocked) arteries in the heart. Arteries in the heart are called coronary arteries. PCI can be successful at relieving chest pain and reducing heart muscle damage during an acute heart attack.
During PCI, a catheter (small tube) with a balloon at the tip is inserted into the diseased coronary artery. The balloon is slowly inflated (filled with air) to open up the artery. Blood is then able to flow more freely through the artery to the heart. A small metal stent (coil) may be inserted at this time to keep the artery open after the procedure.
If patients end up back in the hospital within 30 days of having the procedure, this is known as readmission. Going back to the hospital can put patients at added risk for other health problems and can cause patients and their families more stress.
It is important that hospital staff give patients clear and detailed discharge instructions, including how to correctly manage their conditions and their medications and when patients should seek additional medical care. Hospitals following these safety guidelines will likely have low rates of PCI readmissions.

What does this measure show?

The PCI readmission measure shows the percentage of patients who came back to the hospital for treatment within 30 days following a PCI procedure. Patients who were planning to return to the hospital are not included. This measure includes patients who are 65 years of age or older who are enrolled in Original Medicare (Fee For Service) and who had an unplanned readmission within 30 days
Northwestern Memorial’s performance in this measure is placed into one of three categories based on the results of a statistical analysis that compares our performance with the performance of other hospitals in the National Cardiovascular Data Registry (NCDR) CathPCI Registry. These categories are:
·         Better than CathPCI Registry rate
·         No different than CathPCI Registry  rate
·         Worse than CathPCI Registry  rate
The percentage for Northwestern is higher than the overall rate, but based on statistical analysis, Northwestern is considered to be “No different than” the National Cardiovascular Data Registry rate.
For this measure, a lower number is better.
