The Wound-QoL questionnaire on quality of life in chronic wounds is highly reliable.

The Wound-QoL questionnaire has been tested in a previous study, indicating that the instrument is a reliable and valid measurement for the assessment of HRQoL in chronic wounds. The aim of this study was to examine the test-retest reliability of the Wound-QoL. Patients were asked to complete the Wound-QoL twice within 3-7 days. Next to descriptive statistics, internal consistency was determined. Test-retest reliability was calculated with the intraclass correlation coefficient. The data showed ICCs between 0.79 and 0.86, which can be considered evidence of excellent reliability. Another indicator of very good reliability, high internal consistency of both global score, and subscale scores were found. The availability of the Wound-QoL provides a step forward in allowing measurement of the HRQoL in chronic wounds. The instrument is fit for use to measure outcomes in clinical trials and as well to assess treatment outcomes in routine practice.
