Article Synopsis
- The National Cardiovascular Data Registry's LAAO Registry includes most LAAO procedures in the U.S., and this study aimed to create a model predicting in-hospital adverse events for patients undergoing LAAO with Watchman FLX.
- The study analyzed data from 41,001 procedures, using logistic regression on both development and validation cohorts to identify key predictors of major adverse events, such as age, sex, and health status.
- The resulting risk model showed moderate accuracy and offered a simplified bedside risk score, enabling healthcare professionals to better predict risks and improve decision-making in patient care.
Article Synopsis
- The study investigates the underutilization of cardiac resynchronization therapy-defibrillator (CRT-D) despite existing guidelines, revealing significant differences in its application across hospitals.
- It analyzed Medicare claims data linked with the National Cardiovascular Data Registry from 2010 to 2015, finding that 74% of variation in CRT-D usage was due to the specific hospital rather than patient factors.
- The findings indicate that varying rates of CRT-D use can lead to clinically meaningful differences in hospital-level outcomes, making CRT-D utilization a potential target for improving healthcare quality.
