Participant Flow

We used a targeted recruitment approach by first identifying potentially eligible patients in the electronic health record (EHR) and then emailing or mailing recruitment letters. Letters were followed by a phone call from study staff who described the study and further assessed eligibility by confirming race/ethnicity and health coverage and administering a social risks screener.

Measure
Patient Navigation
Participants randomized to the patient navigation only arm will be referred to a KPNW patient navigator using a standard electronic health record-based referral process. Once the participant has completed the Your Current Life Situation (YCLS) assessment with study staff, the navigator will receive the referral and follow-up with the participant to address the social and economic needs identified. The patient navigator will follow-up with the participant 2-3 times over the 6 month period by phone or in-person about progress with the referral and help address additional needs that may develop during the 6-month intervention. Participant will also receive monthly mailing of American Diabetes Association educational materials. Standard Patient Navigation: Once the participant has completed the YCLS assessment with study staff, the navigator will receive the referral and follow-up with the participant to address the social and economic needs identified. The patient navigator will follow-up with the participant 2-3 times over the 6 months by phone or in-person about progress with the referral and help address additional needs that may develop during the 6-month intervention.
Patient Navigation+Diabetes Self-Management Support
In addition to receiving navigation, participants in this arm will also be referred to Project Access NOW by study staff using REDCap. Project Access NOW will connect participants to a community-based organization based on their preference, previous experience with an agency, geography, and capacity. The CHW will follow-up with the participant to conduct a home visit and follow-up on community-based referrals already placed by the KPNW patient navigator and assess for additional needs. The timing of the diabetes self-management training will be based on the needs of the participant. Diabetes Self-Management Training: The Decision-making Education for Choices in Diabetes Everyday (DECIDE) program is a nine-module, literacy adapted diabetes and cardiovascular disease education and problem-solving training program. Participants are taught the five steps of problem solving with each module going in depth on a single step: 1) identify the problem; 2) brainstorm possible strategies for problem resolution; 3) select the most appropriate strategy; 4) apply the strategy; 5) evaluate the effectiveness of the strategy. During the six months, CHWs will have weekly or bi-weekly contract with participants in-person or by phone to deliver the DECIDE modules and address social and economic needs.
