PS1-1d: Use of CER Hub to Evaluate Outcomes of Smoking Cessation Services, a Behavioral Treatment

organizations. We assessed the internal validity of the measures through analysis of the manual chart review data. Results: Abstractors as a group (n = 3) reliably identified components of PA counseling, including non-specific advice, personalized advice, and referral for PA, in approximately 25% of encounters from a health plan that had implemented EVS. Significantly fewer instances of PA counseling were found in encounters from a second health system without EVS. Conclusions: This preliminary work supports the development of strategies to create a Mediclass program to automatically search the ambulatory component of EMR for these measures. We plan to assess PA counseling before and after the implementation of EVS, which has occurred at different times in different regions of KP, allowing a lagged baseline design for evaluation of relationships between EVS, PA counseling, and health outcomes.
