Abstract 238: Causes Of Readmission In Congestive Heart Failure Patients: Analysis Of 2,536,439 discharges
Introduction: Congestive heart failure (CHF), a major cause of morbidity, is associated with a high 30-day re-admission rate and economic burden on health care. However, detailed description of the causes and preventability of readmissions after CHF are lacking. Determination of the causes of 30-day re-admissions can help hospitals to formulate strategies to reduce readmission and improve quality of life. This study was done to determine causes of re-admission within 30-days after index visit from CHF.
Methods: We used Agency of Healthcare Research and Quality sponsored Healthcare Cost and Utilization Project’s Nationwide Inpatient Sample (NIS) data to extract data. NIS represents 20% of all hospital data in US. Patients discharged with CHF during years 2009-2011 were identified using ICD 9 codes of 398.91, 428.0, 428.1, 428.20, 428.21, 428.22, 428.23, 428.30, 428.31, 428.32, 428.33, 428.40, 428.41, 428.42, 428.43 and 428.9. Patients readmitted within 30 days were identified and categorized based on admitting diagnosis.
Results: We identified a total of 2,536,439 admissions for CHF nationwide during the study period with 630,998 patients readmitted within 30 days (re-admission rate of 24.88%). Out of these, CHF was responsible as a primary diagnosis for 236,572 readmissions (37.49%) and secondary diagnosis for 319,178 readmissions (50.58%). Renal failure was primary diagnosis in 25,652 readmissions (4.07%), arrhythmia in 23,580 readmissions (3.74%), septicemia in 21,891 readmissions (3.47%) and pneumonia in 20,875 readmissions (3.31%).
Conclusions: Strategies to reduce 30-day readmissions secondary to CHF should be focused on control of risk factors for congestive heart failure, renal failure, arrhythmia, septicemia and pneumonia.
