Kaiser Permanente has decided to use a single health risk assessment vendor for all regions.

Kaiser Permanente, Oakland, Calif., a large health maintenance organization company, has been testing several assessment programs since 2005.

Kaiser Permanente decided to standardize on a single program, offered by HealthMedia Inc., Ann Arbor, Mich., so that it would be using uniform procedures to decide which plan members should be encouraged to use the HMO’s weight management, smoking cessation, stress management and nutrition programs, according to HealthMedia.
