QOLP-17. YOGA THERAPY AS A SUPPORTIVE CARE STRATEGY FOR FAMILY CAREGIVERS OF HIGH GRADE GLIOMA PATIENTS: RESULTS OF 3-ARM PILOT RANDOMIZED CONTROLLED TRIAL

Abstract

Abstract BACKGROUND This pilot RCT compared the feasibility and preliminary efficacy of a dyadic versus individual yoga intervention as a supportive care strategy for family caregivers of high grade glioma patients. METHODS Caregivers completed self-reported assessments of QOL (SF-36) and caregiver burden (CRA) and were then randomized to a patient-caregiver dyadic yoga (DY), caregiver yoga (CY) or usual are (UC) arm while patients were undergoing standard radiotherapy. Both yoga programs were delivered over 15 sessions either in-person or via videoconference (Zoom). All groups were re-assessed at the end of treatment and then again 3-months later. RESULTS We consented 76 dyads (59%) and randomized 23 to the DY, 22 to the CY, and 22 to the UC arm. Attendance in the DY was higher than in the CY group (means, DY=12.23, CY=9.00, P=.06, d=.57). Caregivers reported significantly more overall subjective benefit in the CY compared to the DY arm (means, CY=1.39, DY=1.81, P< .05, d=1.45). Caregivers slightly favored the in-person delivery (means, in person: 1.48; zoom: 1.82, P=.10; d=.77). A clinically significant, medium effect size was found for improved QOL in favor of the CY over the DY group (means, CY=49.45, DY=44.45; F=3.58, P=.07; d=.67). Caregivers in the CY group reported less caregiving-related health declines compared to the DY group (means, CY=2.18; DY=2.48; F=4.23, P< .05; d=.42). Caregivers in the CY group reported less caregiving-related financial burden than the UC group (means: CY=2.79; UC=3.21; F=3.32, P=.08; d=.35). CONCLUSION Despite lower attendance, caregivers in the CY arm reported greater subjective overall benefit, experienced better mental QOL and less caregiver burden compared with those in the DY and UC comparison arms. It appears that individual rather than dyadic delivery may be a superior supportive care approach for this vulnerable caregiver population. An adequately powered, larger trial of this intervention strategy is warranted.
