  • When I began my treatments back in May, the original greeter at the door was a bit sullen, but the greeter who eventually replaced her (I never did get her name) was a joy to see and chat with both entering and exitingthe Cancer Center. The security guards were also cheerful.

  • When I found out I had cancer I was really nervous. From the first appointment I knew I was in good hands. Everyone who came in contact with me was so professional. Southcoast was recommended by my best friend who had gone thru the same situation a few months before. Thankfully I took her advice. The Doctors and Staff were excellent. I can not thank them enough. While I hope I never need their services again I will always suggest and praise the Southcoast Cancer Center.

Southcoast Health physician profiles now feature star ratings.  Below, you’ll find frequently asked questions about our process for calculating the ratings.

Why does Southcoast publish survey ratings online?
Southcoast is dedicated to providing patients and consumers with helpful information about the quality of our patients’ experiences. Star ratings published on our physician biography pages are based on actual responses from patients of that particular physician to patient satisfaction surveys that are distributed and processed by a national patient satisfaction survey vendor.

Who receives the survey?
Our vendor sends surveys via SMS or email to all patients seen in our outpatient physician practices who have a valid smart phone number or email address on file with Southcoast Health. Surveys are sent to patients within a few days of their appointment.

How is the Patient Satisfaction Star Rating Calculated?
Star ratings are calculated using an average of all survey responses to each of three questions: Courtesy and Respect of Staff, Provider Overall Rating, and  Willingness to Recommend Provider’s Office.  The star rating displayed on our physicians’ main biography page represents the average of the three measures for that particular physician.
