Multicomponent Intervention Study- Blood Donors With High Cholesterol

This is a single center randomized, two arm trial. The two study arms include usual care (standard notification) and implementation bundle intervention. UT Southwestern Medical Center will be the main study site and Carter Blood Care will serve as the recruitment site.

Screening/Baseline visit: Donors agreeing to participate in the study will be informed of study procedures and will provide informed consent. A 20 mL blood sample as well as a urine sample will be obtained for eligibility screening laboratories and baseline LDL-C.

Follow-up phone call: At 3 months post-randomization, participants in both arms will be briefly contacted by phone by the Research Assistant to thank them for their participation and to answer any study related questions.

End of study 6 month visit. Participants will engage in a virtual visit for end of study procedures. At this follow-up visit, the Research Assistant will assess for any adverse events and direct the participant to collect a fasting blood sample for repeat LDL-C measurement. The Research Assistant will administer an electronic survey and knowledge questionnaires. Additional clinical visits as desired by the participants' physicians will be allowed at their discretion.
