Principle 12. Multifaceted Interventions: Multifaceted
interventions are more effective than single-component interventions.
Effective SMS is typically provided by multifaceted
rather than single-component interventions.6,11,12,44,93 Multi -
faceted interventions include patient registries that identify
patients with specific chronic conditions94 and linkage to
appointment recall systems,95 evidence-based guidelines, and
outcome measures. In a review of trials of smoking cessation
involving physicians and nonphysicians, Kottke et al. concluded
that multifaceted interventions were more successful when
teams of providers were involved and that combinations of
group and individual sessions produced better outcomes than
either alone.96 Better outcomes were predicted by the number of
interventions and the number of reinforcing sessions.96
