The Relationship Between Quality of Life and Health-Related Quality of Life in Young Males with Duchenne Muscular Dystrophy

AIM: This study investigated the relationship between quality of life (QoL) and health-related quality of life (HRQoL) and assessed factors other than health that contribute to differences in QoL in young males with Duchenne muscular dystrophy (DMD). METHOD: In this cross-sectional study, QoL and HRQoL measures were completed by 98 parents and 85 children. The Quality of My Life (QoML) questionnaire measured QoL and HRQoL as single-items, and the Pediatric Quality of Life 4.0 Generic Core (PedsQL) questionnaire was used as a multidimensional measure of HRQoL. Simple regression was used to examine the relationship between single-item measures of HRQoL and QoL. Multivariable regression was used to investigate factors that may contribute to difference in QoL and HRQoL. RESULTS: While ratings of QoL and HRQoL were significantly correlated with one another, HRQoL only accounted for 21% and 44% of the variability in QoL by child- and parent-reports respectively. None of the factors measured contributed ratings of the child\u27s QoL to be much higher than HRQoL. INTERPRETATION: QoL and HRQoL are related but distinct constructs as rated by children with DMD and their parents. Further research is needed to elucidate factors outside HRQoL that contribute to QoL. WHAT THIS PAPER ADDS: Quality of life (QoL) and health-related quality of life are distinct concepts rated by young males with Duchenne muscular dystrophy (DMD) and their parents. Factors outside of \u27health\u27 contribute to overall QoL in the paediatric population with DMD. This article\u27s abstract has been translated into Spanish and Portuguese.

Fear of hypoglycaemia: defining a minimum clinically important difference in patients with type 2 diabetes

<p>Abstract</p> <p>Background</p> <p>To explore the concept of the Minimum Clinically Important Difference (MID) of the Worry Scale of the Hypoglycaemia Fear Survey (HFS-II) and to quantify the clinical importance of different types of patient-reported hypoglycaemia.</p> <p>Methods</p> <p>An observational study was conducted in Germany with 392 patients with type 2 diabetes mellitus treated with combinations of oral anti-hyperglycaemic agents. Patients completed the HFS-II, the Treatment Satisfaction Questionnaire for Medication (TSQM), and reported on severity of hypoglycaemia. Distribution- and anchor-based methods were used to determine MID. In turn, MID was used to determine if hypoglycaemia with or without need for assistance was clinically meaningful compared to having had no hypoglycaemia.</p> <p>Results</p> <p>112 patients (28.6%) reported hypoglycaemic episodes, with 15 patients (3.8%) reporting episodes that required assistance from others. Distribution- and anchor-based methods resulted in MID between 2.0 and 5.8 and 3.6 and 3.9 for the HFS-II, respectively. Patients who reported hypoglycaemia with (21.6) and without (12.1) need for assistance scored higher on the HFS-II (range 0 to 72) than patients who did not report hypoglycaemia (6.0).</p> <p>Conclusion</p> <p>We provide MID for HFS-II. Our findings indicate that the differences between having reported no hypoglycaemia, hypoglycaemia without need for assistance, and hypoglycaemia with need for assistance appear to be clinically important in patients with type 2 diabetes mellitus treated with oral anti-hyperglycaemic agents.</p
