  • It was perfect

  • Better communication between support staff and the patients. Sometimes what happens is, when you call scripts, you get a issue between the pharmacy and the physician's office. Each pointing fingers back and forth that leaves the patient in the lurch. So there needs to be a better process of confirmation that it was sent. So, perhaps when it's sent that the patient gets a text message that it was sent to the pharmacy. So that when there's an issue with the pharmacy saying it hasn't received it*

  • De Theroux is an extremely intelligent and compassionate individual who always puts the patient first. Additionally, his sense of humor has a very calming effect on his patients.

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.
