The state of the unit: variable care models in paediatric acute care cardiology units documented by the fourth iteration of the Paediatric Acute Care Cardiology Collaborative (PAC ³ ) Hospital Survey

BACKGROUND: ) have not been formally reassessed and shared, despite significant growth in the field. METHODS: centres were surveyed in September 2023 via REDCap. Descriptive statistics were performed. RESULTS: centers. Diverse unit composition exists with 37% of centres utilising a single, dedicated acute care cardiology unit, 28% using mixed-specialty acute care units, and 19% using acuity adaptable units, housing critical and acute care patients in one physical space. Since 2017, acute care cardiology-dedicated multidisciplinary staff has increased (physical therapy (PT): 0 to 4; occupational therapy (OT): 1 to 5; speech-language pathology (SLP): 0 to 4; PharmD: 7 to 26). There is heterogeneity in utilisation of many of the resources and therapies used in acute care cardiology, and use of ventricular assist devices on the acute care cardiology unit has increased. CONCLUSION: .
