Left atrial appendage occlusion (LAAO) is approved for non-valvular atrial fibrillation (AF) in patients who are at high risk of stroke but unable to tolerate anticoagulation. We studied the causes and predictors of readmission after LAAO.
National Readmission Database (NRD) 2013 to 2014 was utilized to select study cohort. International Classification of Diseases, 9th revision (ICD-9CM) procedure code 37.90 was used. Admission within 90 day of index admission was considered as early readmission. Hierarchical two-level logistic models were used to evaluate outcomes.
Among study cohort (n=1209), 20.3% (n= 246) were readmitted within 90 days of discharge following index admission. Most common etiologies for readmission were cardiac (40.04%, Heart failure-14.67%), respiratory (9.01%), GI (14.62%). Ischemic stroke/TIA happened in 1.69% of patients. Highest number of readmissions happened on 8th day after discharge (n= 8). Significant predictors of readmission were Anemia (OR 2.09, 95% CI 1.25-3.4), Peripheral vascular disease (OR 2.26, 95% CI 1.29-3.9).
We identified high-risk population for readmission following LAAO as well as trends and most common causes of readmission, which could be utilized to implement individualized health care transition to reduce readmission, related cost.
