these studies, 26 used proportion of days covered, 23 used medication possession ratio, and 72 used self-reported questionnaires (e.g., the Morisky Scale) to assess MMA. About 50% of the studies included more than one method for measuring MMA, and different variations of medication possession ratio and proportion of days covered were used for measuring MMA. Conclusions: There appears to be no standardized method to measure MMA. With an increasing prevalence of polypharmacy, more efforts should be directed toward constructing robust measures suitable to evaluate adherence to complex regimens. Future research to understand the validity and reliability of MMA measures and their effects on objective clinical outcomes is also needed.
The data suggest that a somewhat less profound anesthesia with gel is clearly preferred by the patients because of the low incidence of post-procedure problems as compared to conventional injection anesthesia. The median WTP is likely in excess of the acquisition cost of the product, which indicates a favorable cost-benefit ratio for the individual patient.
Objectives: To compare the improvement of hip and knee osteoarthritis during treatment with naproxen. Methods: Men and women aged 40 to 75 years with symptomatic osteoarthritis of the knee or hip of at least three months' duration participated in a six week placebo controlled, double blind study with naproxen 500 mg twice daily as one treatment arm. Naproxen was given to 403 patients (280 knee, 123 hip) and placebo to 108 patients (75 knee, 33 hip). WOMAC (Western Ontario and McMaster Universities osteoarthritis index) 3.1 visual analogue scale and SF-36 (36 item short form health survey) were used to assess response to treatment between baseline and week 6. Results: There were no differences at baseline between knee and hip osteoarthritis for any of the WOMAC subscales or SF-36 domains. Improvement was between 4 and 7 mm greater for knee than for hip for all WOMAC subscales (pain, D = 4.7 mm (p = 0.03); stiffness, D = 6.6 mm (p = 0.004); function, D = 4.8 mm (p = 0.06)). Effect size was about 0.8 for all WOMAC subscales for the knee and between 0.5 and 0.6 for the hip. Knee patients treated with naproxen improved 4.6 (p = 0.033) more than hip patients for SF-36 bodily pain and 10.3 (p = 0.014) more for SF-36 role-physical. Conclusions: Patients with knee osteoarthritis improved more with naproxen treatment than patients with hip osteoarthritis, as monitored by WOMAC and the SF-36 domains bodily pain and role-physical. These findings warrant further investigation and strongly suggest that efficacy of treatment of osteoarthritis of knee and hip should be evaluated separately.
We conclude that the measures introduced in 2005 significantly improved the value of the information in the registry, which has contributed greatly to our understanding of patients' real-world experience with enzyme replacement therapy for Fabry disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
