What is Changes in Quality‐of‐Life After Pacemaker Implantation: Responsiveness of the Aquarel Questionnaire about?

**STOFMEEL, M.A.M., et al.: Changes in Quality‐of‐Life After Pacemaker Implantation: Responsiveness of the Aquarel Questionnaire.** Before being introduced for widespread use, health status instruments should be evaluated for reliability, validity, and responsiveness to relevant clinical changes. In a previous study the validity and reliability of Aquarel, a disease‐specific quality‐of‐life (QOL) questionnaire for pacemaker patients, were tested and found satisfactory. The purpose of this study was to assess the sensitivity to change in health of Aquarel. A cohort of 51 patients was assessed at baseline and at 4–6 weeks after pacemaker implantation. We compared the sensitivity to change over time on the Aquarel scores to the scores on the SF‐36 using various techniques (__t__‐test value, effect size, standard error of measurement). Using the 1‐standard error of measurement (SEM) criterion for clinically relevant change, Aquarel seemed to provide better classification of patients compared to the SF‐36 alone. This study supports the value of Aquarel as a disease‐specific measure of QOL in pacemaker patients.
