From time to time, Quality Management in Health Care (QMHC) is the fortunate beneficiary of the efforts of a team of guest, or issue, editors. For this Fall 2009 issue of QMHC, David Litaker, MD, PhD, has assembled a group of colleagues to share their thoughts and research findings on the role of context in health care quality management. QMHC thanks Dr Litaker and his co-Issue Editors, Mats Brommels, MD, PhD, and Darcy Terris, PhD, for their leadership and their contributions to this issue.
