Clinical decision support (CDS) tools in electronic health records (EHRs) often face low uptake due to limited usability, workflow integration, and other implementation issues. We recently designed and implemented the STRATIFY-CDS tool, which calculates a validated risk-prediction model and recommends disposition for emergency department (ED) patients with acute heart failure. Despite applying human-centered design and implementation science strategies, initial utilization in the first 3 months of the STRATIFY-CDS tool was just 3%.

Background: The Kansas City Cardiomyopathy Questionnaire-12 (KCCQ-12), a patient-reported outcome measure for adults with heart failure, is associated with hospitalizations and mortality in clinical trials. Curated data sets from controlled trials differ substantially from pragmatic data collected from real-world settings, however, and few data exist on the KCCQ-12's predictive utility in clinical practice.

Objectives: This study sought to evaluate the predictive utility of the KCCQ-12 for hospitalizations and mortality when administered during outpatient heart failure care.

The transition from hospital to home can be a vulnerable and challenging period for patients, especially those living with multiple chronic conditions (MCC), as evidenced by their disproportionately high rates of readmission. Low health literacy, complexity of a new medication schedule, and "post-hospital syndrome" can all contribute to suboptimal adherence to discharge instructions. Timely and adequate support during transitional care has the potential to prevent adverse events and avoidable hospital readmissions.

Article Synopsis
  • Clinical prediction models are valuable tools intended to improve clinical decision making, but their use in practice is limited due to issues like incomplete data in electronic health records (EHR).
  • The article proposes a new submodel approach that enhances prediction model application by refining the model coefficients to better handle real-time data inconsistencies.
  • Simulation results indicate that this new method performs well across different scenarios and is better suited for practical implementation than existing methods, specifically in identifying emergency department patients with acute heart failure eligible for safe discharge.
