P004 - 30-Day Hospital Readmission Rates, Frequencies, and Heart Failure Classification for Patients with Heart Failure


The purpose of this DNP project is to determine 30-day hospital readmission rates, frequencies, and heart failure classification for patients with heart failure. A retrospective chart review was conducted at an urban hospital in Memphis, TN. The study was deemed exempt by the Review Board. Electronic medical records were queried from July 1, 2019 through December 31, 2019 for heart failure ICD-10 codes beginning with the prefix 150 and a report was generated. The total number of heart failure admissions was computed and compared to national average. Using age ranges 40-80, the number of patients readmitted withing 30 days was computed and descriptive and inferential statistics were computed using Microsoft Excel and R. A total of 3524 patients were admitted for heart failure within the six-month time frame. Of those, 297 were re-admitted within 30 days for heart failure exacerbation (8.39%). An annual estimate was computed (16.86%), well below the national average (21%). Of those re-admitted within 30 days, 50 were readmitted sequentially, on multiple occasions, ranging from two to eight readmissions. The median age was 60 and 60% were male. Due to the skewed distribution (most readmitted twice), nonparametric statistics were used for correlation. While graphic display of charts suggested a trend for most multiple readmissions due to diastolic dysfunction and least number due to systolic heart failure, there was no statistically significant correlation between age and number or multiple re-admissions (Spearman rank, p = 0.6208) or number of multiple re-admissions and heart failure classification (Kruskal Wallis, p =0.2553).
