Motion Graphic Training for Scrub Nurses in Hip Surgery
Motion Graphic Video-Based Training and Its Effect on Scrub Nurse Performance During Dynamic Hip Screw Surgery in Iran: A Pilot Randomized Controlled Trial
연구 개요
상태
상세 설명
This is a pilot randomized controlled trial conducted at Valiasr Teaching Hospital, Arak University of Medical Sciences, Iran, from December 2024 to July 2025. The study is designed according to CONSORT guidelines for pilot and feasibility trials.
A total of 30 undergraduate operating room technology students in their 6th or 8th semester are randomly assigned to intervention (n=15) and control (n=15) groups using block randomization with a computer-generated random numbers table. Both groups receive routine clinical training from the same instructor at the beginning of the course. The intervention group additionally views a 15-minute motion graphic video demonstrating DHS surgical steps, which they can watch unlimited times during the 15-day internship period. The video content includes introduction of surgical instruments, anatomy review, surgical table setup, patient preparation and draping, and instrument delivery to the surgeon.
Students' performance as first scrub nurse is assessed twice: on the first day of internship (pre-test) and at the end of the 15-day internship (post-test) by a blinded independent evaluator using a validated 43-item checklist covering preoperative (13 items), intraoperative (24 items), and postoperative (6 items) phases. The checklist has been validated for content validity and reliability through expert review and pilot testing.
To prevent contamination, the control group is enrolled first, and intervention group students are asked not to discuss the educational video with others. The video will be provided to the control group after study completion for educational equity.
Data will be analyzed using paired and independent t-tests. Effect sizes will be calculated for between-group comparisons.

Scrub Nurse Performance Score
기간: Baseline (day 1) and day 15 (end of 15-day internship)
|
Performance assessed using a validated 43-item researcher-made checklist covering preoperative (13 items), intraoperative (24 items), and postoperative (6 items) phases.
Each item is scored on a three-point scale: 0 = does not perform, 1 = performs incompletely, and 2 = performs correctly.
The total score ranges from 0 to 86, with higher scores indicating better performance.
The checklist was validated for content validity and reliability through expert review and pilot testing.
