Learning Health Systems and the Revised Common Rule.

Quality improvement (QI) is an important function of learning health systems, and public policy should promote QI activities. Use of systematic methodologies in QI has prompted substantial confusion regarding when QI is human subjects research under the Common Rule, and this confusion persists with the revised Rule. Difficulty distinguishing research from QI imposes costs on the quality improvement process. I offer guidance to IRBs to mitigate these costs and suggest a new regulatory exclusion for minimal risk quality improvement activities. [ABSTRACT FROM AUTHOR]
