IntroductionThe effect on quality of life by healing leg ulcers is not known and no validated disease-specific tool is available for measuring health-related quality of life (HRQoL) for people with venous leg ulcers. The objective of this paper was to compare four generic instruments [MOS 36-Item Short-Form Health Survey (SF-36); EuroQol (EQ); McGill Short Form Pain Questionnaire (SF-MPQ) and the Frenchay Activities Index (FAI)] used for measuring HRQoL in people with venous leg ulcers, and to offer guidance on the most appropriate tool for researchers.MethodsTwo hundred and thirty-three patients with venous leg ulcers were recruited as part of a randomised controlled trial of the cost-effectiveness of community leg ulcer clinics. Subjects completed questionnaires containing the four instruments on three occasions (initial assessment, 3 and 12 months). The discriminative and evaluative properties of the four instruments were compared.ResultsAll four instruments were acceptable to patients, taking a mean of 19.3 (SD 6.3) min to complete. At initial assessment, the SF-MPQ had poorer discriminative properties than the other three instruments and was not able to distinguish between the different patient groups in relation to age and ulcer duration. The FAI was good at discriminating between the different patient groups (at initial assessment) in relation to age, mobility and ulcer size. At the three-month follow-up, the SF-MPQ was more responsive than the other measures and detected changes in HRQoL, whereas the EQ and SF-36 did not. At 12 months, the SF-MPQ still identified differences and the SF-36 and EQ also did at this stage.ConclusionIn the absence of a validated condition-specific tool for measuring changes in general health status for patients with venous leg ulcers, we make the following recommendations. For evaluating the outcome of interventions with a short-term follow-up (three months) in a clinical study we recommend the SF-MPQ and for 12-month follow-up in a clinical study the SF-36, with or without the SF-MPQ.
