One-year rehospitalisation after percutaneous coronary intervention: a retrospective analysis

Area of Science:

• Cardiology
• Public Health
• Health Services Research

Background:

• Percutaneous coronary intervention (PCI) is a common procedure for ischemic heart disease.
• Understanding rehospitalisation rates is crucial for healthcare system efficiency and patient outcomes.
• Denmark's universal healthcare system provides a unique setting to study healthcare utilization post-PCI.

Purpose of the Study:

• To determine the incidence and causes of rehospitalisation within one year after PCI.
• To identify predictors associated with rehospitalisation for angina/myocardial infarction versus other causes.

Main Methods:

• Retrospective analysis of 17,111 patients undergoing PCI between January 2010 and September 2014.
• Identification of one-year readmissions and categorization of causes.
• Statistical analysis to identify predictors of rehospitalisation, including demographic factors, comorbidities, and indication for PCI.

Main Results:

• The overall one-year rehospitalisation rate was 50.4%.
• Angina/myocardial infarction accounted for 49.7% of readmissions, while other reasons comprised 50.3%.
• Predictors for angina/MI readmissions included female gender, diabetes, and specific PCI indications (STEMI, NSTEMI). Predictors for other readmissions included female gender, diabetes, age, and high comorbidity index.

Conclusions:

• Approximately half of patients treated with PCI experience rehospitalisation within one year.
• Comorbidity significantly impacts rehospitalisation rates in patients with ischemic heart disease.
• Identifying specific predictors can aid in targeted interventions to reduce readmissions.
