The Patient Experience Star Rating reflects our patients’ perception of how well their Mount Sinai provider communicated with them during an office visit. The Star Rating is based on patient responses to three questions on a patient experience survey, a standardized questionnaire sent to verified patients and distributed by a third party vendor, Press Ganey. Responses are measured on a scale of 1 to 5, with 5 being the best score.
