Motion Graphic Training for Scrub Nurses in Hip Surgery

8 de julio de 2026 actualizado por: Hamed Parnikh, Arak University of Medical Sciences

Motion Graphic Video-Based Training and Its Effect on Scrub Nurse Performance During Dynamic Hip Screw Surgery in Iran: A Pilot Randomized Controlled Trial

This pilot randomized controlled trial evaluates the effect of motion graphic video-based training on the performance of scrub nurse students during dynamic hip screw (DHS) surgery. A total of 30 operating room technology students in their 6th or 8th semester are randomly assigned to either an intervention group (n=15) or a control group (n=15). The intervention group receives routine clinical training plus a 15-minute motion graphic video demonstrating DHS surgical steps, while the control group receives only routine clinical training. Performance is assessed before and after a 15-day internship using a validated 43-item checklist.

Descripción detallada

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.

Experimental: Motion Graphic Video Training
Students received a 15-minute motion graphic video demonstrating DHS surgical steps, in addition to routine clinical training, with unlimited access during the 15-day internship.
A 15-minute animated video demonstrating the steps of proximal femur fracture surgery using a dynamic hip screw (DHS). Content includes surgical instruments, anatomy review, table setup, patient draping, and instrument delivery to the surgeon.
Comparador activo: Routine Clinical Training
Students received only routine clinical training in the operating room, including attending the OR, performing the scrub nurse role, and receiving direct feedback from the clinical instructor during the 15-day internship.
Standard clinical training in the operating room including attendance, performing the scrub nurse role, and receiving direct feedback from the clinical instructor during the 15-day internship.

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Scrub Nurse Performance Score
Periodo de tiempo: 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.
Baseline (day 1) and day 15 (end of 15-day internship)
Within-Group Pre-Post Score Changes
Periodo de tiempo: Baseline to day 15
Comparison of Scrub Nurse Performance Scores (measured using a validated 43-item checklist, total score range: 0-86, with higher scores indicating better performance) before and after the 15-day internship within each group using paired t-tests.
Baseline to day 15
Between-Group Post-Test Score Comparison
Periodo de tiempo: Day 15
Comparison of Scrub Nurse Performance Scores (measured using a validated 43-item checklist, total score range: 0-86, with higher scores indicating better performance) between the intervention and control groups after the 15-day internship using independent t-tests.
Day 15
