Studies are published every month demonstrating that physicians who implement national guidelines at the local level improve such patient outcomes as mortality, length of stay, and time to clinical stability. Dr. Corrigan notes that there are abundant examples of guideline adherence boosting quality outcomes, and cites as a prime example the AHA’s Get With the Guidelines program (www.american heart.org/presenter.jhtml?identifier=1165), which has documented quality gains in coronary artery disease, stroke, and heart failure patients.
We’re finally shedding light on how to tackle patient handoff and hospital readmission issues. … If we were to solve just that one piece, we can more easily start implementing other clinical guidelines.

Barriers to Acceptance and Adherence
But there are obstacles to guideline adherence, and widespread practice pattern variation remains a huge national problem. Providers in some regions of the country can use twice the resources as their counterparts in other regions and bring no additional benefit to patients (see “Medicare Fee Inspection,” p. 30). The Dartmouth Atlas of Health Care says unwarranted practice variation is responsible for as much as 30% of wasted healthcare spending in the U.S.—a cost that reformers are anxious to eliminate.
The traditional culture of autonomy in the medical profession is perhaps the most difficult and enduring barrier to reducing unjustified practice variation: clinicians don’t automatically follow guidelines, many treat them more as options than as true standards, and organizations do not sufficiently enforce or reward adherence to guidelines, wrote researchers in a special 2005 issue of Health Affairs focusing on guidelines.2
