Assessing the Impact of a Training Intervention on Venous Compression Bandaging Application: A Factorial Design Randomised Trial.

At baseline, compression bandaging quality was low among advanced practice nursing students.

• Mean CCB score (0-7 scale) at baseline was 3.78
• Installation conformity at baseline was 52%
• Study enrolled 50 advanced practice nursing students (APNS) in France
• Assessments were performed on a mannequin leg

The one-hour training intervention did not significantly improve the primary outcome of compression bandaging quality (CCB score) compared to controls.

• Adjusted difference in CCB score between intervention and control groups: -0.43
• 95% CI: -1.01 to 0.15, indicating no statistically significant improvement
• The trial used a 2×2 factorial randomised open-label design
• The intervention was a one-hour behaviourist-based training session

A significant interaction between bandage type and training intervention was found for installation conformity.

• Installation conformity showed a tendency to improve with system B following the intervention
• Installation conformity showed a tendency to decrease with system A following the intervention
• Two different compression bandage types (system A and system B) were compared within the factorial design

Improvements in compression bandaging observed at one month were not sustained at three months.

• The study assessed sustainability of the training intervention over a three-month follow-up period
• Any improvements seen at the one-month follow-up point were lost by the three-month assessment
• This indicates the brief training intervention lacked long-term efficacy for skill retention

Application time decreased over the course of follow-up, and system B was applied more efficiently than system A.

• Application time was a secondary outcome measure
• System B demonstrated more efficient application compared to system A across the study period
• The reduction in application time occurred regardless of training intervention assignment

Brief, behaviourist-based training was identified as insufficient to achieve lasting compression bandaging skill improvement.

• Authors identified the need for repeated group practice, feedback, and integration into relevant clinical contexts
• The training duration was one hour
• The findings suggest that more comprehensive educational approaches are required to enhance compression bandaging proficiency
• Compression therapy is described as the gold-standard treatment for venous leg ulcers (VLU)
