Good patient care takes time. Unfortunately, there never seems to be enough of it, particularly as appointment durations are abbreviated to satisfy volume demands, and documentation requirements increase. Point-of-service references intended to answer questions (common and otherwise) are multiplying in an effort to meet the need for quick, concise, and complete information. The Mount Sinai Expert Guides are one such attempt. In the case of the gastroenterology version, a roughly 500-page soft-cover printed text is complemented by an online companion program.
