Abstract

Chronic wounds have a major socioeconomic impact due to their frequency, chronicity, and societal costs. Patients experience substantial quality of life (QoL) impairments. The use of questionnaires for a continuous assessment of QoL and resulting interventions to improve the situation of the individual are an important cornerstone of a guideline-based wound care. The aim of this study was to investigate the validity of the Wound-QoL questionnaire. Patients with chronic wounds from two different centers were included in the prospective study. All patients completed the Wound-QoL and two other QoL questionnaires (European Quality of Life-5 Dimensions, EQ-5D, and Freiburg Life Quality Assessment for wounds, FLQA-wk) at baseline and at two more time points (4 and 8 weeks, respectively). Wound status was defined with an anchor question. Two hundred and twenty-seven patients (48.5% women) participated in the study. Mean age was 66.9 years (range 17-96, median 69.5). Indications were venous leg ulcers (40.1%), pyoderma gangraenosum (14.1%), diabetic or ischemic foot ulcers (5.3%), pressure ulcers (2.6%), and other etiologies (30.0%). The Wound-QoL showed good internal consistency, with high Cronbach's alpha in all the subscales and in the global scale in all time points (>0.8). Convergent validity was satisfactory since there were significantly (p ≤ 0.001) good correlations with the EQ-5D (range = 0.5-0.7) and FLQA-wk global score (r > 0.8) at every time point. Responsiveness was high, too. The Wound-QoL is a simple, valid tool for the longitudinal assessment of QoL in patients with chronic wounds. This questionnaire is suitable for use in clinical trials, quality of care studies and clinical routine.
