Abstract
e21571 Background: We developed and validated the values questions for the Person-Centered Oncologic Care and Choices (P-COCC) ACP intervention, which combines an informational care goals video with a brief patient values interview. Herein, we studied (primarily) the acceptability of P-COCC, and (secondarily) its effects on wellbeing and decisional conflict. Methods: Patients (pts): English-speaking with GI cancer, ≤ monthly followup in MSK medical oncology clinics and believed by their oncologist able to complete study measures and to survive 1-12 months. Consented pts randomized 2:2:1 to P-COCC vs. video alone (V) vs. usual care (UC). Questionnaires: administered baseline and at next follow-up visit on validated measures of wellbeing, and on follow-up only, decisional conflict. P-COCC arm pts also completed 3 Likert scales (was the intervention helpful, comfortable and recommended to others?); a positive score on ≥1 of 3 indicated acceptability for that pt. Results: During screening from 9/2014-11/2016, 202 potentially eligible pts were approached. 51 (25%) declined participation (most common reason, N = 31 = not wanting to discuss the topic). 151 consented and were randomized; 99 (66% of the 151) completed study measures (most common attrition reason, N = 34 = disease progression or death). Of the 99, 63% male; mean age 61 years; mean ECOG PS 1; most common cancer types colorectal, gastroesophageal, and pancreatic; most white race, Christian religion and married. The primary aim was met: Among 33 pts, 32 (97%, 95%CI: 0.84-0.99, p < 0.001) rated P-COCC acceptable. Mean distress scores (0-10) increased (0.43) in the P-COCC arm but decreased in the V (-0.04) and UC (-0.21) arms (p = 0.03 and 0.04, P-COCC vs V and UC, respectively). There were no significant pre-post change scores on other measures of wellbeing (anxiety, depression, stress, acceptance, QOL), or intergroup differences in decisional conflict. Conclusions: Our values-based ACP paradigm is acceptable but may increase distress in GI cancer outpatients. Further studies will investigate underpinnings and follow-up duration of these observations, and ways to best support cancer patients (with any cancers, and regardless of prognosis) in ACP. Clinical trial information: NCT01912131.
