Devon Hill Associates harnesses the research power of mystery shopping to analyze and improve the patient experience in hospitals and healthcare organizations — and the marketing and sales effectiveness of senior living and long-term care organizations. Medical mystery shopping is a research tool for observing, assessing and analyzing the patient experience through the eyes of incognito patients and visitors. Trained mystery shoppers, posing as real patients, offer healthcare providers valuable insight into the efficiency and responsiveness of their operations, as well as their perceptions about the care being provided.
