Review of early hospitalization after percutaneous coronary intervention

Abstract Percutaneous coronary intervention (PCI) is the commonest modality of revascularization in patients with coronary artery disease. Data suggests that 30-day readmissions are not uncommon. The rate of readmission after PCI is highly influenced by the cohort and the healthcare system studied, with 30-day readmission rates reported between 4.7–15.6%. Understanding the reasons for readmission is important because it is a quality of care indicator, in addition to being a burden to patients and healthcare services. Studies consistently report that majority of readmissions within 30 days are due to a cardiac related disorders or complication related. While there are many predictors of readmissions it is not known whether any of the modifiable predictors could have prevented the readmission. This review aims to evaluate readmission rates, causes and predictors in the current literature. Furthermore, we explore the cohort inclusion criteria and patient characteristics to better understand the variation in reported readmission rates and causes across different studies.
