primary care suggests the need for such interventions.
But if primary care settings are to focus their quality
improvement and individual patient-care efforts on
those conditions that have the greatest effects on health
and the best cost effectiveness, it is important to have
evidence-based information about the relative priority
of all effective preventive services. Yarnall et al.5 has
shown that if primary care clinicians tried to provide
each of the services recommended by the USPSTF for
each patient seen, it would take 7.5 hours per day for
just that task.5 Thus, some prioritization information
seems absolutely necessary.
