Patient-centered Precision Medicine Lab Result Communication for Older Adults

For adults ≥65 years and their providers, the investigators will test the usability and design of a tool to replace standard uniform reporting of lab results to patients and their providers with a new personalized Electronic Health Record (EHR) lab result communication tool that: 1) extracts patient-level data from the EHR; 2) calculates individual risk; and 3) for patients with very low risk, communicates the individualized risk information. The investigators will employ a range of User Experience (UX) research methods to understand how patient and provider users interact with the new lab result communication tool and to assess their comprehension of the lab results. This study will be conducted with both patient and provider participants. The patient participant portion of this study uses a four-arm, design to evaluate three newly designed laboratory result communication template reports compared with the current standard (control) communication. The provider participant portion of this study is non-randomized; all provider participants will review all four template reports. This will include live semi-structured interviews with the participants and review of the template report(s) of the Chronic Kidney Disease (CKD) lab result communication tool. An anonymous in-person template report feedback survey will be provided to the participants to gauge their understanding of the template report(s), clarity of the information presented, and overall satisfaction with the tool. This will be a single-visit interaction with the participant in the UCLA Health geriatric or general medicine patient waiting room. The survey was revised after an initial pilot.
