About These Ratings
The BJC Medical Group (BJCMG) partners with an independent survey company, National Research Corporation Health (NRC), to gather feedback directly from patients about their experiences. NRC sends electronic surveys to BJCMG patients following a medical visit, asking them to evaluate different aspects of their care. Once a provider receives at least 30 reviews, responses are calculated by our survey vendor and posted to the provider's profile using a five-star rating system. By collecting information in this way, you can trust that the reviews posted on our website are from verified patients of that provider and represent all responses to the survey.
We refer to BJC Medical Group, Washington University Physicians, clinical services in Illinois provided by Washington University Physicians in Illinois, Inc., and independent providers who actively participate at a BJC-affiliated hospital. Providers make no payments for these referrals, and our selections are based on your needs and preferences.
