Insights
Left atrial appendage occlusion (LAAO) is an alternative stroke prevention method. LAAO has a 9.2% readmission rate, with gastrointestinal bleeding being the most common cause.
Area of Science:
- Cardiology
- Interventional Cardiology
- Health Services Research
Background:
- Percutaneous left atrial appendage occlusion (LAAO) offers a non-drug alternative for stroke prevention in non-valvular atrial fibrillation patients unsuitable for oral anticoagulation.
- Data regarding 30-day readmission rates following LAAO procedures is limited, necessitating further investigation.
Purpose of the Study:
- To analyze the rates and causes of 30-day readmissions after percutaneous left atrial appendage occlusion (LAAO).
- To identify independent predictors associated with 30-day readmission following LAAO procedures.
Main Methods:
- The Nationwide Readmissions Database (NRD) was utilized to identify patients undergoing LAAO from 2016 to 2018.
- Complex samples multivariable logistic regression models were employed to determine predictors of 30-day readmission.
Main Results:
- A total of 29,367 patients underwent LAAO, with a 30-day readmission rate of 9.2%.
- The primary causes for readmission were gastrointestinal bleeding (18.5%), heart failure (13.1%), and infection (7.3%).
- Independent predictors for readmission included female gender, heart failure, anemia, chronic lung disease, end-stage renal disease, acute kidney injury, and bleeding/transfusion events.
Conclusions:
- The overall 30-day readmission rate post-LAAO is 9.2%, with non-cardiac causes like gastrointestinal bleeding being most prevalent.
- Strategies to reduce in-hospital complications and optimize post-procedural antithrombotic regimens may be crucial for decreasing LAAO readmissions.
Abstract:
Percutaneous left atrial appendage occlusion (LAAO) provides a nonpharmacological alternative of preventing stroke in patients with non-valvular atrial fibrillation who are poor candidates for oral anticoagulation. Data on 30 day readmission measures following LAAO is limited. Index LAAO procedures and 30 day readmissions were identified using the Nationwide Readmissions Database (NRD) from 2016 to 2018. The rates and causes of 30 day readmissions were studied. Complex samples multivariable logistic regression models were used to identify predictors of 30 day readmission. Among 29,367 patients undergoing LAAO, the rates of 30 day readmissions were 9.2%. The most common overall cause of 30 day readmission was gastrointestinal bleeding (18.5%), followed by heart failure (13.1%), and infection (7.3%). Female gender (OR1.22; 95% CI 1.08-1.38), HF (OR 1.30; 95% CI 1.15-1.47), anemia (OR 1.37; 95% CI 1.11-1.68), chronic lung disease (OR 1.42; 95% CI 1.25-1.62), End stage renal disease (OR 2.75; 95% CI 2.13-3.55), Acute kidney injury (OR 1.66; 95% CI 1.25-2.20), bleeding/transfusion (OR 1.63; 95% CI 1.28-2.09) were found to be independent predictors of 30 days Readmission. The overall rate of 30 day readmission after LAAO was 9.2% with non-cardiac causes (gastrointestinal bleeding) being the most common. Reducing in-hospital complications and identifying optimal post procedural anticoagulation/antithrombotic regimen may help decrease readmissions following LAAO.
