Some of us wear shorts and skirts anyway, ignoring furtive glances or curious comments, while others just hide their veins under hose or pants. A third option is available: treatment.

Patient Ratings and Comments
About Our Survey

The Patient Rating score is based on responses given during the CAHPS Patient Experience Survey. Responses are measured on a 10-point scale, with 10 being the best score. These scores are then translated to a 5-point scale in order to display results in a 5-star rating. Comments are also gathered from the same survey and displayed in their entirety with the exception of any language that may be considered slander, libel or contain private health information, which will be removed prior to publishing the comments.
