Point-of-Care Ultrasound (PoCUS) Teleeducation Curriculum for Hospital-at-home Care

Since July 2024, the National Health Insurance Administration (NHIA) has been implementing a pilot Hospital-at-Home (HAH) Acute Care Program to curb hospital admissions. Point-of-Care Ultrasound (PoCUS) is considered the most promising imaging tool for this model. Replicating the hospital's familiar environment-its staffing patterns, diagnostic workflows, and medication protocols-in a patient's home or nursing facility is almost impossible, posing a major challenge to care teams. Medical-simulation training offers a solution, yet current PoCUS courses remain organ-based and lack scenario-based simulations that prepare physicians for HAH practice. This two-year study will create a PoCUS curriculum and outcome-assessment tools tailored to HAH, adapting previously validated Entrustable Professional Activities (EPA) instruments to three HAH scenarios: pneumonia, urinary tract infection, and soft-tissue infection. Year 1 will develop scenario-based simulation courses and matching EPA tools, and train peer instructors who receive full PoCUS instruction for the three scenarios. Year 2 will randomly assign learners to compare two teaching models-peer training with remote supervision and scenario simulation versus traditional PoCUS training-evaluated with an Objective Structured Clinical Examination (OSCE) scored by EPA forms across multiple domains. The project aims to establish normative standards for PoCUS training and assessment in HAH, confirm the feasibility of peer training with remote supervision, and provide a platform to train HAH medical teams nationwide, including those in rural areas.
