SECONDARY outcome

Timeframe: Satisfaction measures will be surveyed at baseline and at 6 months and reported as a single change score

Population: Clinic staff in the study clinics.

In order to assess clinician and staff satisfaction with the eReferral and paper-based referral systems, a single-item "The steps I need to take to address my patients' tobacco use are efficient and well designed" was administered to healthcare system clinical staff. The response format was 1 = Strongly disagree; 2 = Disagree; 3 = Mildly disagree; 4 = Feel neutral; 5 = Mildly agree; 6 = Agree; 7 = Strongly agree. Higher scores indicate greater satisfaction with the assigned intervention (EHR-based vs Fax-based referral systems). The item is not part of any existing validated scale and was created for purposes of the project; this item was selected from a larger set of items and determined to be the most appropriate measure of overall staff satisfaction.
