Simulation-Based Cardiac Point-of-Care Ultrasound Program to Improve Clinical Outcomes in Acute Heart Failure Patients

maanantai 11. toukokuuta 2026 päivittänyt: Duke University

Co-design and Implementation of a Simulation-Based Cardiac Point-of-Care Ultrasound Program to Improve Clinical Outcomes in Acute Heart Failure Patients

The aim of this study is to co-design a cardiac POCUS simulation training intervention and implementation strategy for EM clinicians and evaluate the effectiveness of the cardiac point-of-care ultrasound (POCUS) simulation-based training (CPST) and CPG implementation. By performing this study, the investigators hope to improve diagnostic processes and time-to-diuretic dosing for acute heart failure (AHF) patients.

Yksityiskohtainen kuvaus

Cardiac disease is the leading cause of mortality worldwide, with over 6.7 million Americans with acute heart failure (AHF) presenting with 1 million annual emergency department (ED) visits. Point-of-care ultrasound (POCUS) is a critical bedside tool that can expedite diagnosis and treatment in AHF patients. However, gaps in POCUS training remain that limit clinical utilization. Simulation-based training reinforces technical skills for clinical application. Prior work achieved high procedural knowledge (70% passed, 18% SD) and technical skills (95%, 6% SD) in emergency medicine (EM) clinicians using a simulation nerve block model, with retention at 3-months post-intervention. The current proposed study builds on this work, using the Implementation Research Longitudinal Framework (IRLM) to translate knowledge into clinical skills through simulation-based POCUS training for EM physicians and Advanced Practice Providers (APPs) to improve time-to-diuretics and AHF patient clinical outcomes. Specific Aim 1 uses adaptive Experience-Based Co-design (EBCD) to co-design a cardiac POCUS simulation training intervention and implementation strategy for EM clinicians The cardiac POCUS training workshop and reinforcement sessions will be co-designed with ED leadership, ultrasound faculty, and key stakeholders. Participants will then perform cardiac and lung POCUS using standardized clinical practice guidelines (CPG) in AHF patients as part of clinical care. Specific Aim 2 is the intervention assessment. We will assess pre-, post, and 6-month post-simulation participant POCUS skills using validated ultrasound self-efficacy scales, image interpretation tests (knowledge), and simulated scenario performance (technical skills). Specific Aim 3 evaluates the effectiveness of the cardiac POCUS simulation-based training and clinical practice guideline implementation. The investigators will perform a quasi-experimental pre-/post design by interrupted time series with one year of data before and after intervention implementation. We will perform a quasi-experimental pre-/post design interrupted time series with one year of data before and after intervention implementation in three diverse EDs. Our primary clinical outcome is time-to-diuretic dose in ED heart failure patients.11 PROCTOR-guided outcomes include effectiveness, provider adoption, and clinical POCUS uptake/utilization.

IPD-suunnitelman kuvaus

All data will be collected in hospital secured platforms including Duke REDCap, the current clinical Butterfly Enterprise POCUS archiving system, and Epic electronic health records. All data will be de-identified at the collection step and kept as de-identified data for our research purposes. Data will be collected in digital format and stored using standardized file types such as .csv, .txt, .docx, .mp3. The total data volume will cover about 175 participants across 2-3 hospital sites.

The research community will have access to data when the award ends. As required by NHLBI, studies will also be created that contain the data used for every publication. Those studies will be shared when the pre-print is available and have digital object identifiers (DOI) to aid in findability. The investigators will include the DOI in relevant publications. NHLBI will make decisions about how long to preserve the data.
