Feasibility and utility of the montreal cognitive assessment in routine clinical exams and telehealth visits in neuro-oncology

Abstract Cognitive dysfunction (CD) is common among primary brain tumor (PBT) patients and adds to the overall symptom burden. Standardized assessments able to be incorporated into routine clinical in-person and telehealth care are needed. Here, we report the feasibility, utility, and satisfaction with use of the Montreal Cognitive Assessment (MoCA) in telehealth and clinical settings by trained clinical providers. Feasibility and provider satisfaction were assessed through survey responses, and patient performance on the MoCA, after a reliability check, was reported through descriptive statistics. Seventy-nine MoCAs on 71 patients were completed in clinic (n=55) or telehealth (n=24). Majority of patients were white (83%) males (54%) with high grade PBTs (66%), and half of patients had completed at least a college education. In clinic, providers (n=9) reported the MoCA took 5-20 minutes to complete, was easy to incorporate into routine practice (78%), believed it was accurate in assessing cognition (67%), and was useful in determining treatment (88%). The average in-person MoCA score was 25 (range: 6 to 30), with 31% of scores classified as abnormal (≤26). In telehealth, providers (n=11) found the administration of the MoCA prior to attending participation in the telehealth visit helpful (75%), discussed the results with their clinical team (75%) and patient (63%), and believed the MoCA was accurate in assessing cognition remotely (63%). On average, patients took 13 minutes (9-22) to complete testing, with three tests discordant on reliability scoring and one patient unable to complete testing. The average telehealth MoCA score was 26 (12-30), with 29% of scores classified as abnormal. Overall, testing was feasible in both clinical and telehealth settings, and providers reported satisfaction with its use. Future studies should evaluate validity in a larger sample and include analysis of relevant cut-off scores, impact of disease, tumor treatment, and genomic predispositions.
