Blue Cross and Blue Shield policyholders will soon be able to compare the costs and effectiveness of different types of treatment for a variety of conditions.

This spring, the state’s largest health insurer will offer customers Wiser Health, a personalized online decision-making tool that assesses possible treatments. Consumers can use that information to select the most cost-effective and cost-appropriate treatment for them, according to Wise Together Inc., the tool’s designer. The result is improved health and lower costs.

Being sick or injured can be stressful, said Dr. David Carmouche, Blue Cross chief medical officer. The Wiser Health tools provide easy-to-understand information about their health conditions so Blue Cross members feel more in control, better able to discuss options with their doctors, and to choose the treatments that work for the patients.
