Development and psychometric assessment of the COPD and Asthma Sleep Impact Scale (CASIS)
<p>Abstract</p> <p>Background</p> <p>Patients with respiratory disease experience disturbed sleep, but there is no widely accepted measure of sleep impairment due to respiratory disease. We developed and evaluated the psychometric performance of a patient-reported measure to assess the impact on sleep due to respiratory disease, the COPD and Asthma Sleep Impact Scale (CASIS).</p> <p>Methods</p> <p>Identification of the items forming the CASIS was guided by patient interviews and focus groups. An observational study involving patients from the US and UK was then conducted to assess the psychometric characteristics of the measure.</p> <p>Results</p> <p>Qualitative data from 162 patients were used to develop the CASIS (n = 78 COPD; n = 84 asthma). The observational study included 311 patients with COPD and 324 patients with asthma. The final seven items used in the CASIS were identified based on factor and item response theory analyses. Internal consistency was 0.90 (COPD) and 0.92 (asthma), and test-retest reliability was 0.84 (both groups). In the COPD sample, CASIS scores were significantly correlated with the Saint George's Respiratory Questionnaire scores (all p < 0.0001) and differed significantly by patient-reported disease severity, exacerbation status, and overall health status (all p ≤ 0.005). In the asthma sample, CASIS scores were significantly correlated with the Asthma Quality of Life Questionnaire scores (all p < 0.0001) and differed significantly by clinician and patient-reported disease severity, exacerbation status, and overall health status (all p ≤ 0.0005).</p> <p>Conclusion</p> <p>The CASIS shows good internal consistency, test-retest reliability, and construct validity and may be useful in helping to understand the impact that COPD and asthma have on sleep outcomes.</p
Conversaciones y reacciones en relación con la hipoglucemia grave (CRASH): resultados de España de una encuesta global en personas con diabetes tipo 1 o diabetes tipo 2 tratada con insulina y cuidadores
Introduction: Information on experience/management of severe hypoglycaemic events (SHEs) among people with insulin-treated diabetes (PWD) and caregivers (CGs) providing care to PWD was sought. Materials and methods: An online cross-sectional survey was conducted in eight countries. Inclusion criteria: PWD (aged ≥ 18 years; self-reported type 1 [T1D] or insulin-treated type 2 [T2D] diabetes; experienced ≥1 SHE [hypoglycaemia requiring external assistance] in past 3 years); CGs (layperson aged ≥18 years; caring for PWD meeting all criteria above except age [≥4 years]). This descriptive analysis provides data from Spain. SHE-associated data relate to the most recent SHE. Results: Across all groups (T1D PWD, n = 106; T2D PWD, n = 88, T1D CG, n = 87; T2D CG, n = 96), 76–89% reported that the SHE occurred at home; most common cause was eating less than planned (38–53%). Most usual action during the SHE was to intake carbohydrates (67–84%); glucagon use was low (9–36%). Discussion of the SHE with their healthcare provider (HCP) was reported by 70–75% of PWD. During the SHE, 35–69% of PWD/CGs reported feeling scared, unprepared and/or helpless. Conclusions: Most SHEs occurred outside the healthcare setting; treatment therefore depends greatly on CGs. SHEs have a negative emotional impact on PWD/CGs, underscoring the need for HCPs to discuss SHEs with PWD/CGs, and to provide tools and strategies to prevent and effectively manage SHEs
