As society moves toward requiring greater accountability for medical practice, clinical practice guidelines based on expert evaluation of relevant data have received greater attention as a potential tool for measuring quality. However, because using guidelines in quality measurement is relatively new, little exploration has occurred regarding what it means to actually “follow” a guideline. This is particularly concerning in an environment in which adhering to recommendations or not might have consequences for patient referrals or financial incentives.Guidelines are designed to assist the clinician in making appropriate decisions about the patients' care.1 A good guideline provides a range of appropriate options—but only appropriate options—that a clinician can choose among for individual treatment decisions. During guidelines development, available evidence is considered and used as the foundation for recommendations, with high level evidence preferred. When high level evidence is not available, guidelines developers use lower level evidence, including phase II studies and retrospective analysis. Experts evaluate the evidence available at the time and make recommendations expecting that, over time, new data will drive changes in the guidelines.2Guidelines developers consider key decisions that must be made in providing appropriate care. They cannot, however, address every possible situation that might arise. In developing the NCCN Clinical Practice Guidelines in Oncology™, for example, panel members invoke the “5% rule”: if a situation will probably not be encountered in more than 5% of the patient population under consideration, that situation is not addressed in the guidelines. This strategy limits undue complexity and emphasizes that, even...
