Detaillierte Beschreibung
This quasi-experimental study aims to compare two instructional models-physician-led versus peer NP-led POCUS training-and their effects on learners' outcomes and clinical skill performance.
Methods:
Sixty NPs, either in practice or under training, will be recruited and non-randomly assigned to either the experimental group (peer-led instruction) or the control group (physician-led instruction), based on their course availability, simulating real-world clinical education allocation:
- Experimental group: Hands-on training led by NPs who have completed a structured POCUS curriculum and passed both teaching and practical assessments.
- Control group: Hands-on training delivered by specialist physicians.
To ensure the quality and standardization of instructional delivery and operational procedures, two groups of nurse practitioners received the training program in separate cohorts. The educational intervention was structured into two phases: the first phase consisted of a two-hour online course covering fundamental ultrasound theory, relevant anatomical structures, and key points in clinical application; the second phase was a four-hour in-person hands-on workshop focusing on clinical scanning techniques and image interpretation skills. The instructional content encompassed five core structures: (1) inferior vena cava (IVC) assessment, (2) pleural effusion detection, (3) ascites identification, (4) hydronephrosis evaluation, and (5) bladder volume estimation and urinary retention interpretation.
Participants completed a pre-test prior to the training, a first post-test immediately after the course, and a second post-test three months later. The assessment tools included: (1) a POCUS knowledge questionnaire, (2) a self-confidence scale, (3) an image interpretation assessment, and (4) an Objective Structured Clinical Examination (OSCE).

Experimental: Nurse Practitioner-Led Peer Teaching Group
Participants in this arm will receive a structured POCUS training program delivered by trained nurse practitioner instructors.
The intervention includes a 2-hour online course covering basic ultrasound principles, relevant anatomy, and clinical applications, followed by a 4-hour hands-on practice session focused on integrative volume status assessment, including IVC, pleural effusion, ascites, hydronephrosis, and bladder assessment.
|
Participants 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.

Aktiver Komparator: Experimental
Participants in this group will receive the same structured POCUS training program delivered by trained physician instructors.
The program includes a 2-hour online lecture and a 4-hour hands-on practice session focused on integrative volume status assessment, including inferior vena cava, pleural effusion, ascites, hydronephrosis, and bladder assessment.

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.
