The Patient Satisfaction Rating is an average of all responses to the care provider related questions from our nationally recognized Press Ganey Patient Satisfaction Survey. Patients that are treated in outpatient or hospital environments may receive different surveys, and the volume of responses will vary by question.
Responses are measured on a scale of 1 to 5 with 5 being the best score.
The comments are submitted by patients and reflect their views and opinions. The comments are not endorsed by and do not necessarily reflect the views of St. Luke's University Health Network.
