Key takeaways:
- About 50% of enrollees with excessive eRADAR scores had MCI or dementia.
- Solely 30% of contributors accomplished their visits.
- The researchers acknowledged the necessity for outreach to underrepresented communities.
An digital screening device reveals promise for detecting cognitive impairment and dementia threat in older adults, however outreach is required to spice up participation to evaluate its feasibility in a main care setting, per to a presentation.
The digital well being report Danger of Alzheimer’s and Dementia Evaluation Rule (eRADAR)” “is an [electronic health record]-based threat rating to determine people who find themselves at excessive threat of getting undiagnosed dementia,” Deborah E. Barnes, PhD, MPH, epidemiologist within the Weill Institute for Neurosciences on the College of California, San Francisco, stated on the Alzheimer’s Affiliation Worldwide Convention.
Information have been derived from Barnes DE, et al. Evaluating focused dementia screening of high-risk sufferers in main care: Preliminary outcomes from the digital well being report Danger of Alzheimer’s and Dementia Evaluation Rule (eRADAR) pragmatic randomized trial. Introduced at: Alzheimer’s Affiliation Worldwide Convention; July 27-31, 2025; Toronto.
An ongoing scientific trial, whose foremost function is to ascertain whether or not eRADAR’s implementation in a primary-care setting will enhance the speed of dementia analysis, is being carried out at UCSF and at Kaiser Permanente Washington Well being Analysis Institute.
Eligible contributors have been aged 65 years and older and didn’t have a dementia analysis or dementia medicines. Researchers used eRADAR to display screen EHRs for sufferers who have been “excessive threat” based mostly on roughly 30 variables.
“Demographic variables embrace issues like age and intercourse. It contains some persistent well being circumstances and diagnoses like diabetes and coronary heart failure. It contains some very important indicators like underweight and a few medicines,” Barnes stated.
Well being care utilization variables comparable to main care and ED visits are among the many variables as properly, she continued.
Sufferers with eRADAR scores within the highest 15% to twenty%, indicating biggest threat, have been contacted first by way of mail and adopted by telephone calls. On the primary-care stage, sufferers have been randomized to obtain an invite for a “mind well being” evaluation by way of in-person go to, video or telephone or obtain typical care.
The first final result for the examine is the speed of dementia analysis after 12 months, with secondary outcomes associated to qualitative assessments of the examine on these concerned.
A baseline mind well being go to was carried out both by telephone or video convention and led by a licensed clinician. Sufferers have been inspired to have a care accomplice alongside for the evaluation.

Points associated to reminiscence or pondering, together with evaluation of day by day residing actions, potential despair signs and the Montreal Cognitive Evaluation (MoCA), have been examined. At UCSF, the intervention was supplied in English, Spanish, Cantonese and Mandarin, with English solely at Kaiser.
Following the session, a affected person abstract and suggestions for remedy have been supplied, with a scientific notice handed onto the first care supplier. These with suspected dementia have been inspired to comply with up with their PCP inside a month, after which the PCP would order testing to make a analysis.
Interventionists then monitored affected person charts for 4 months. In case of an absence of follow-up, researchers referred to as sufferers as a reminder, and if no new analysis was made, extra assets have been supplied.
A post-visit survey moreover assessed the affected person’s acceptance of the remedy and satisfaction with the intervention.
At UCSF, 1,271 people have been break up on a 1:1 foundation between the intervention arm (n = 683) and commonplace care arm (n = 588), whereas among the many 3,417 contributors at Kaiser, 1,715 got the intervention and 1,702 positioned in commonplace care.
In line with outcomes, at UCSF, 637 people obtained examine outreach, 222 (35%) agreed to a go to and 197 (31%) accomplished the visits. At Kaiser, the figures have been 1,706 who obtained outreach, 554 (32%) who agreed to a go to and 505 (29%) who accomplished visits.
“They didn’t reply their telephone. Perhaps they weren’t studying their mail,” Sascha Dublin, MD, PhD, senior investigator, doctor and affiliate affiliate professor at Kaiser, stated throughout the presentation. “Some simply weren’t .”
Sufferers who accomplished visits had a imply age of 83.4 years at KPWA and 83.6 years at UCSF; have been 57% feminine at KPWA and 52% feminine at UCSF; and 88% white at KPWA and 61% white at UCSF.
Relating to the outcomes of the mind well being visits, 21% of the 197 at UCSF and 17% of the 505 at Kaiser have been suspected dementia circumstances, whereas 31% on the former location and 32% on the latter confirmed proof of gentle cognitive impairment.
Amongst those that accomplished the examine visits at UCSF, 50% did so by video and 57% had a care accomplice current; at Kaiser, 74% have been carried out in individual and 72% had a care accomplice included.
Within the affected person satisfaction survey, contributors have been requested in the event that they discovered the go to useful, in the event that they discovered the interventionist put them comfy and in the event that they felt snug speaking about mind well being. For UCSF enrollees, settlement was roughly 90% to 96% for all three questions and at Kaiser it was roughly 91% to 98%.
“This can be a inhabitants who now is ready to get enhanced care. They may have simpler entry to new disease-modifying therapies,” stated Dublin,. “We predict eRADAR reveals numerous promise for possibly figuring out individuals who might get early intervention, possibly a behavioral intervention.”
Such interventions would emphasize bodily exercise or new pharmacologic therapies, Dublin continued.
Among the many causes researchers discovered for lack of participation have been time and logistic challenges, cultural stigma, and extra urgent well being considerations and circumstances in an getting older inhabitants, significantly in these aged 90 years and older.
Information additional confirmed that at UCSF, a considerably greater proportion of non-Hispanic white English-speaking contributors accomplished their go to in contrast with English-speaking Asian, Black and Hispanic contributors. As well as, a better proportion of non-English-speaking Asian contributors accomplished their visits vs. Hispanic contributors.
At Kaiser, non-Hispanic white enrollees had the best completion charges, with decrease charges present in Hispanic, Black and Asian sufferers.
“It is actually necessary that we hold pursuing analysis and develop new methods to assist participation amongst communities of shade and folks whose most popular language isn’t English,” Dublin added.
