Effectiveness of anti-tumor necrosis factor agents in the treatment of rheumatoid arthritis: observational study.

Objective: The efficacy of anti-tumor necrosis factor therapies in rheumatoid arthritis has been demonstrated in randomized clinical trials. The purpose of the present study was to evaluate the effectiveness of these agents for the treatment of rheumatoid arthritis in a real-world setting.

Method: This retrospective chart review included patients from 6 clinics in the United States.

A United States cost-benefit comparison of an apodized, diffractive, presbyopia-correcting, multifocal intraocular lens and a conventional monofocal lens.

Purpose: To demonstrate the value, from the patient's perspective, of an apodized, diffractive, presbyopia-correcting multifocal intraocular lens (MF-IOL) compared to a conventional monofocal intraocular lens (CM-IOL).

Setting: Open-label, multi-site U.S.

Effects of an increase in prescription copayment on utilization of low-sedating antihistamines and nasal steroids.

Background: Health plans are using 3-tier copayment designs and other methods to control utilization that shifts drug costs to plan members. There is a need to determine the effects of increased member cost sharing on drug utilization and drug costs.

Objective: To assess the impact of a 10 US dollars increase in prescription copayment in a public employer health plan for 2 classes of drugs used for allergic rhinitis.
