Clinical Trial Data on Atrial Fibrillation Risk Tool and Cardiac Monitoring

Prospective clinical trial data from hospitalized ischemic stroke patients without known atrial fibrillation. The study compares a preintervention period (October 2018 - June 2019) to an intervention period (March 2021 - March 2022) where an EHR-based tool calculated 5-year AF risk. The analysis tests for an interaction between predicted AF risk and the intervention period on the incidence of extended cardiac monitoring within 6 months of discharge.

Use Cases

• Analyze the interaction between predicted 5-year AF risk and the intervention period on extended cardiac monitoring incidence.
• Compare the incidence of extended cardiac monitoring within 6-months of discharge between preintervention and intervention periods.
• Stratify analysis of cardiac monitoring utilization by BPA (best-practice advisory) completion status.
• Model the relationship between the clinical trial period (preintervention vs. intervention) and patient outcomes using a Fine and Gray model.

Strengths

• Data is from a prospective clinical trial with defined preintervention and intervention periods.
• Study design includes a multivariable Fine and Gray model for statistical analysis.
• Focus on a specific clinical question regarding AF risk estimation tool impact on monitoring.

Limitations

• Sample size and number of rows are unknown, limiting assessment of statistical power.
• Column names and specific data features are not provided, restricting detailed analytical planning.
• Geographic scope and specific hospital setting are not detailed, which may limit generalizability.
