One in five. That is how many older adults screened through two Ontario community paramedicine programs showed signs of potential cognitive impairment, and if that number does not reshape how this province funds senior care, it is hard to imagine what will.

New research led by Gina Agarwal at McMaster University, published in BMC Health Services Research, looked at 385 adults enrolled in Community Paramedicine at Clinic and Community Paramedicine at Home. These programs do something quietly sensible: they move paramedics out of the ambulance and into subsidized housing buildings and private living rooms, where they check blood pressure, chronic disease, and mental health before a crisis forces a 911 call. When researchers layered on the Mini-Cog, a brief three-word memory task paired with clock drawing, the results stopped us cold: 18.54 percent of clinic participants and 20.14 percent of home-visit participants screened positive for potential cognitive impairment.

What most people miss is why those two numbers look so much alike. These were strikingly different groups. Clinic attendees averaged 74.2 years of age, and 75.74 percent lived alone. Home-visit participants averaged 78.5 years, carried 2.42 chronic conditions on average, and were considerably more frail. Two groups this different should have produced very different risk rates. Instead, the difference was statistically insignificant. The researchers' interpretation makes sense to us on the ground: paramedics applied clinical judgment about whom to screen, enriching both samples with higher-risk individuals. That judgment is an asset in the field, but it also flags the need for clearer screening protocols, so the province knows exactly how selection is actually working.

Here is what we keep coming back to: the insight is not the statistic itself. It is the delivery model. Dementia stays notoriously underdiagnosed in primary care, and seniors who live alone or cannot easily travel rarely show up for cognitive assessment until symptoms are far along. A trusted paramedic, already in the room, can piggyback a few minutes of screening onto a visit that is already happening, then route a positive result to a family physician for follow-up. The programs run alongside partners across Niagara, Durham, Rainy River, Guelph-Wellington, Norfolk, Cochrane, and Oxford, which tells us the model holds in urban, rural, and remote settings alike.

Ontario faces a choice, and it is the kind of question our communities need to weigh in on: keep waiting for crises, or fund the community infrastructure that catches risk years earlier. Earlier identification is not a cure. It buys time, and that time is not small: to review medications, connect families with supports, and let seniors help plan their own futures while they still can. To be fair, and we want to be honest with you, this was an observational study of 385 adults, not a randomized trial, and a positive screen is a flag, not a diagnosis. That honesty matters. The recommendations here should be treated as a starting point to test, not settled law. But a province that claims to work for everyone should not ignore a warning this clear, delivered one kitchen-table visit at a time.
