Abstract 15722: Demographic Factors for 30 Day Readmission Following Percutaneous Coronary Intervention Procedure: Analysis of Nationwide Inpatient Sample Data
Introduction: Acute myocardial infarction is a major cause of morbidity and mortality in USA with percutaneous coronary intervention (PCI) as a mainstay of therapy. Short term hospital readmissions account for a significant portion of health care budget and much of the focus recently has been on reducing 30 day readmission rate. This study was done to determine demographic parameters associated with 30 day readmission rate after index PCI.
Methods: Nationwide Inpatient Sample (NIS) data was used to extract data of patients discharged after PCI during index admission for years 2009-2011. Patients were identified by Clinical Classification Software code 45, corresponding to ICD 9 procedure codes of 00.66, 17.55, 36.01, 36.02 and 36.05. NIS represents 20% of all hospital data in US. Patients readmitted within 30 days were identified and demographic parameters associated with high readmission rate identified.
Results: We identified a total of 1,784,929 hospitalizations where PCI was performed with 13.04% readmitted within 30 days after index hospitalizations. Elder age (65+), female gender, Medicaid insurance, low median income for zip code and metropolitan areas were associated with high 30 day readmission rate.
Conclusions: This first national study identifies the demographic parameters associated with high 30 day readmission rate. Strategies to reduce morbidity and healthcare cost should be targeted more on these groups with high readmission rate. Study was limited by the fact that the admission for staged PCI could not he differentiated from unplanned readmission. Further studies might be needed to supplement the results.
