Summary
Unplanned readmissions after percutaneous coronary intervention (PCI) are high, particularly following acute procedures. Implementing quality measures can help reduce these readmissions for both elective and acute PCI patients.
Area of Science:
- Cardiology
- Interventional Cardiology
- Health Services Research
Background:
- Prior studies indicate high unplanned readmission rates post-acute percutaneous coronary intervention (PCI).
- Limited data exist outside the USA comparing 30-day unplanned readmissions after elective versus acute PCI.
Purpose of the Study:
- To determine the rates, causes, and predictors of 30-day unplanned readmissions following elective and acute PCI.
- To compare readmission rates between elective and acute PCI procedures.
- To identify factors associated with unplanned readmissions.
Main Methods:
- Analysis of 199,686 PCI encounters in Australia and New Zealand (2010-2015).
- Comparison of 30-day unplanned readmission rates and causes for elective versus acute PCI.
- Logistic regression used to identify predictors of readmission.
Main Results:
- Overall 10.6% unplanned 30-day readmission rate; lower for elective (7.0%) vs. acute PCI (12.7%).
- Non-specific chest pain was the most common readmission cause for both groups.
- Readmissions for acute myocardial infarction and heart failure were significantly higher after acute PCI.
Conclusions:
- High rates of unplanned readmissions occur after both elective and acute PCI.
- Clinical and quality-control interventions are necessary to prevent avoidable readmissions in all PCI settings.

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...
