What Was Measured?

Members who contacted their plan with a problem or to get information were surveyed for the Plan Service rating.

Why Is It Important?

The best HMOs and their doctors communicate with patients about common health risks. For example, a common health risk is sexually transmitted infections in younger, sexually active women. HMOs and their doctors should test younger, sexually active women for sexually transmitted infections like Chlamydia.
