摘要
Background: Overnight observation is the standard of care for uncomplicated elective percutaneous coronary intervention (PCI). However, same-day discharge (SDD) is reportedly safe using predetermined criteria and patient risk categories. Characteristics of patients with SDD have not yet been described. Objective: The purpose of this study was to describe the phenotype of patients appropriate for SDD after PCI without predetermined criteria and patient risk categories. Methods: Analysis of PCI registry data was conducted on patients (n = 2174) who underwent elective and nonelective PCI between January 2012 and June 2014. Preliminary analysis included descriptive statistics, t tests, and chi(2) tests. All variables were analyzed using random forest plot to determine importance of predictors of SDD followed by confirmatory logistic regression. Results: Random forest plot indicated 6 predictors of SDD. Confirmatory logistic regression using a model with all 6 predictors indicated that the model was able to distinguish between patients with SDD and overnight observation after PCI and was statistically significant (chi(2) (7.12, N = 2174) = 511.12, P < .005). Strongest predictors of SDD were stable angina (odds ratio, 5.93 [95% confidence interval, 1.316-26.712]; P = .020) followed by non-ST elevation myocardial infarction/high-risk unstable angina (odds ratio, 1.66 [95% confidence interval, 1.239-2.225]; P= .001). Readmission within 24 hours of SDD after PCI was low at 0.91%. Conclusions: Age, access site, complexity, and number of lesions stented did not preclude SDD. A broader range of patients, particularly patients in higher risk categories (non-ST elevation myocardial infarction and unstable angina), are candidates for SDD.
