AbstractRemote cognitive diagnostic assessment offers numerous benefits, including increased access to care, but it may not always be appropriate, and guidelines are lacking. Our goal was to develop a clinical tool to determine a patient’s suitability for undergoing remote cognitive assessment. A multidisciplinary workgroup, composed of experts in remote assessment, was convened under the auspices of the Canadian Consortium on Neurodegeneration in Aging. Delphi, an anonymous group consensus method, was used to determine ‘red flags’ for remote cognitive diagnostic assessment. The process consisted of one round of flag generation, then two rounds of flag scoring based on effectiveness, reproducibility, and efficiency. In the first round, 11 respondents generated 67 potential flags. In subsequent rounds, 8 and 9 respondents, respectively, scored the flags, yielding 14 red flags that met the predetermined consensus criteria. This research led to the creation of a novel clinical decision-making infographic to support multidisciplinary clinicians in determining a patient’s readiness to undergo remote cognitive and behavioral diagnostic assessment.HighlightsA timely and accessible diagnosis of dementia is crucial for optimal patient care.Although clinicians are increasingly using telemedicine, guidelines on patient suitability for remote cognitive and behavioral assessment are lacking.To address this knowledge gap, we developed a clinical decision-making tool to determine if a cognitive evaluation via telemedicine should be avoided.To synthesize expert opinion, we used the Delphi method, an anonymous group consensus method that reduces eminence bias.In collaboration with knowledge translation experts, an infographic describing the final 14 red flags for remote cognitive assessment was developed for clinicians to determine the appropriateness of patients for remote dementia diagnostic assessment.Research in contextSystematic ReviewPubMed and Google Scholar were used to survey the literature. Our review found that although there was a need for better access to dementia care, a framework to provide such care remotely is in development. We identified a gap in clinical guidelines on contraindications for remote cognitive assessment.InterpretationThis study created a clinical decision-making tool as an accessible infographic for clinicians to use when considering a remote cognitive diagnostic assessment. This guideline is based on expert consensus.Future DirectionsIn future studies, patient and caregiver perspectives should be incorporated into the decision-making process, and this tool should be validated in clinical contexts. Some of the identified flags for remote assessment are modifiable, and strategies to mitigate burden on patients and caregivers are warranted.
