Multicenter Study
Physicians' attitudes and adherence to use of risk scores for primary prevention of cardiovascular disease: cross-sectional survey in three world regions.
To evaluate physicians' attitudes and adherence to the use of risk scores in the primary prevention of cardiovascular disease (CVD). ⋯ Based on a survey conducted in a 'real-world' setting, risk scores are generally not used by a majority of physicians to guide primary prevention in asymptomatic persons at intermediate risk for CVD. Appropriate prescribing of lipid-lowering therapy in such patients is equally neglected. Changing physicians' attitudes towards the use of CVD risk scores is one of several challenges that need to be addressed to reduce the world-wide burden of CVD.

Baseline clinical and health-related quality of life (HRQoL) data from a phase 2, multi-site, international, randomized, controlled trial were analyzed to: (1) characterize the health status of patients with relapsing-remitting multiple sclerosis (RRMS), (2) explore cross-sectional relationships between HRQoL and clinical measures, and (3) evaluate differences in HRQoL scores for subsequent validation as minimally important differences (MID). ⋯ Clinical and HRQoL assessments documented health impairments in physical functioning, fatigue, and cognition among these RRMS patients with relatively short disease duration. HRQoL data varied with clinical measures and contributed new information regarding disease burden. The association between clinical and HRQoL measures was limited to cross-sectional analysis and requires confirmation in longitudinal datasets. These findings reflect an ambulatory, early-stage RRMS population that was mostly European in location or descent. The PAMSI also requires further validation as a measure of patient health status.
