Assessment of internet-based information on statin therapy.

AIMS: The use of statin therapy is deemed to be controversial by mainstream media. Patients increasingly source medical information from the internet, and the use of statins is no exception. This study aims to determine the quality and educational content of statin-focused information on the internet and YouTube. METHODS AND RESULTS: 'Statin' was searched on Google, Yahoo!, Bing, and YouTube. The first 50 results obtained from each search engine and the first 20 YouTube videos were screened by two assessors. Websites were assessed using the Flesch Reading Ease (FRE) score, University of Michigan Consumer Health Website Evaluation Checklist, and a customized scoring system evaluating statin-focused content for quality. Videos were scored using the Journal of the American Medical Association (JAMA) benchmark criteria, Global Quality Score (GQS), and the customized scoring system. Websites scored a median FRE score of 57.5 [interquartile range (IQR) 52.1-62.3], median Michigan score of 36 (IQR 32-41.5), and median content score of 5 (IQR 3.75-7). Good interobserver agreement was demonstrated [Michigan score interobserver coefficient correlation (ICC) = 0.968; content score ICC = 0.944]. Videos scored a median JAMA score of 2, median GQS score of 2.5, and median content score of 2.5. Good interobserver agreement was demonstrated (JAMA ICC = 0.746; GQS ICC = 0.874; content score ICC = 0.946). CONCLUSION: Quality and readability of statin-focused online information are poor. Healthcare professionals should be aware of the limitations of the current available sources and design online resources that are accurate and patient-friendly.

Morphometric and traditional frailty assessment in transcatheter aortic valve implantation.

OBJECTIVES: Frailty is common amongst patients undergoing transcatheter aortic valve implantation (TAVI). The aim of this study was to determine the prognostic relevance of newer objective and traditional measures of frailty after TAVI. METHODS: Consecutive patients were identified from the Leeds Teaching Hospitals Trust TAVI database. Frailty was quantified objectively by measuring the total psoas muscle area (TPMA) on routine computer tomography scans and compared against Canadian Study of Health and Aging Clinical Frailty Score, Katz Index of independence in activities of daily living and Clinician Estimated Poor Mobility. Postintervention morbidity and mortality were examined between these scoring systems. RESULTS: The current study included 420 patients who had undergone TAVI between January 2013 and December 2015. Median clinical follow-up was 4.0 years (interquartile range 2.9-5.0). Standardized measurements of the TPMA were not associated with either postintervention morbidity or mortality. Only the Canadian Study of Health and Aging Clinical Frailty Score was associated with hospital stay (adjusted regression coefficient 0.70, 95% confidence interval 0.04-1.36, P = 0.038) and overall all-cause mortality (adjusted regression coefficient 1.26, 95% confidence interval 1.05-1.50, P = 0.013). There were no significant correlations between TPMA and any of the traditional frailty tools. CONCLUSION: We demonstrate TPMA to be a poor measure of patient frailty when compared with traditional methods of assessment which failed to predict postintervention outcomes. Furthermore, morphometric sarcopaenia correlated poorly with established measures of frailty.
