Outcomes
Primary outcome [1] 257471 0
Wound-related pain (WRP) intensity and quality.
WRP intensity was measured using the Numerical Rating Scale.
WRP quality was measured from data collected using the Wound-related pain at dressing assessment tool - Question 5 on the tool.
Timepoint [1] 257471 0
Measured at baseline and at every dressing change for 12 weeks.
Secondary outcome [1] 262653 0
Health-related quality of life using the validated Cardiff Wound Impact Schedule.
Timepoint [1] 262653 0
Measured at baseline and weeks 4 and 12.
