English and Spanish-speaking vulnerable older adults report many barriers to advance care planning.

Background/objectives: Advance care planning (ACP) rates are low in diverse, vulnerable older adults, yet little is known about the unique barriers they face and how these barriers impact ACP documentation rates.

Design: Validated questionnaires listing patient, family/friend, and clinician/system-level ACP barriers and an open-ended question on ACP barriers.

Setting: Two San Francisco public/Department of Veterans Affairs hospitals.
