This study aims to develop and evaluate a peer-led training program specifically designed for Nurse Practitioners (NPs) to acquire Point-of-Care Ultrasound (POCUS) skills. POCUS, known for its non-invasive nature and real-time imaging capability, has been widely applied in clinical fluid status assessment and plays a pivotal role in enhancing diagnostic efficiency and quality of care. However, current POCUS training resources for NPs in Taiwan remain insufficient, limiting their clinical application and professional visibility. Using a quasi-experimental design, this study investigates the effectiveness of peer-led instruction in strengthening image interpretation, clinical reasoning, and self-efficacy among NPs. The ultimate goal is to establish an evidence-based, nursing-oriented POCUS education model to fill existing gaps in the training system and elevate the role of NPs in multidisciplinary care.

Nurse Practitioner-Led Peer POCUS Training
BehavioralParticipants will receive a structured point-of-care ultrasound training program delivered by trained nurse practitioner instructors. The program includes a 2-hour online lecture and a 4-hour hands-on practice session. Training focuses on integrative volume status assessment, including ultrasound evaluation of the inferior vena cava, pleural effusion, ascites, hydronephrosis, and bladder volume or urinary retention.
Change in POCUS Clinical Performance Score
POCUS clinical performance will be assessed using an Objective Structured Clinical Examination (OSCE). Participants will be evaluated on ultrasound probe positioning, image acquisition, anatomical identification, clinical interpretation, and integration of findings for volume status assessment, including inferior vena cava, pleural effusion, ascites, hydronephrosis, and bladder assessment. Higher scores indicate better clinical performance.
Change in POCUS Knowledge Score
POCUS knowledge will be assessed using a structured 10-item questionnaire covering basic ultrasound principles, organ identification, and clinical applications. Higher scores indicate better POCUS knowledge.
