Differences between patient- and proxy-reported HRQoL using the Wound-QoL

Wound Repair Regen. 2018 May;26(3):293-296. doi: 10.1111/wrr.12662. Epub 2018 Oct 11.


The purpose of this study was to examine the patient- and proxy-report agreement on the Wound-quality of life (QoL) questionnaire to assess health-related QoL in patients with chronic wounds. Patients and their proxies (in this case, relatives) were recruited via different nursing services in Germany and asked to complete the Wound-QoL. Intraclass correlation coefficients were calculated for each Wound-QoL scale and the total score, and weighted Cohen's Kappa coefficients for individual items. Proxies tended to report lower health-related QoL in the Wound-QoL than their relatives with chronic wounds. Agreement between the two perspectives was moderate on single-item level and excellent on scale level. Proxy-reports can be helpful, if patients are unable to provide information, although caution remains when interpreting the results. However, the patient's own perspective remains preferable.
