Scientists reveal how living alone can put people with cognitive decline at risk

CALIFORNIA: One in every four senior Americans with dementia or mild cognitive impairment lives alone, making them vulnerable to risky driving, wandering outside the home, mixing up medications, and skipping appointments.

According to a study led by UC San Francisco and published in JAMA Network Open on August 18, 2023, patients living alone with cognitive decline, whose numbers are expected to rise as the population ages, are not effectively served by the American health system.

For these patients, living alone is a social determinant of health with an impact as profound as poverty, racism and low education, said first author Elena Portacolone, PhD, MBA, MPH, of the UCSF Institute for Health and Aging and the Philip R. Lee Institute for Health Policy Studies.

In this qualitative study, researchers interviewed 76 health care providers, including physicians, nurses, social workers, case workers, home care aides and others. Participants worked in memory clinics, home care services and social services and other places in California, Michigan and Texas.

The providers raised concerns about patients missing medical appointments, failing to respond to follow-up phone calls from the doctor’s office and forgetting why appointments were made, leaving them vulnerable to falling off the radar. “We don’t necessarily have the staff to really try to reach out to them,” said a physician in one interview.

Some patients could not assist their doctor with missing information on their chart, leaving the providers uncertain about the pace of their patient’s decline. Many had no names listed as emergency contacts, “not a family member, not even a friend to rely on in case of a crisis,” according to a case manager.

These patients were at risk for untreated medical conditions, self-neglect, malnutrition and falls, according to the providers. A house service coordinator also noted that calls to Adult Protective Services were sometimes dismissed until a patient’s situation became very serious.

One consequence of the shaky infrastructure supporting these patients was that they were not identified until they were sent to a hospital following a crisis, like a fall or reaction to medication mismanagement. Some were discharged without a support system in place. In one case, a patient was sent home with a taxi voucher, a situation that a psychiatrist likened to “sending a kid out to play on the freeway.”

These findings are an indictment of our health care system, which fails to provide subsidized home care aides for all but the lowest-income patients, said Portacolone.

“In the United States, an estimated 79% of people with cognitive decline have an income that is not low enough to make them eligible for Medicaid subsidized home care aides in long-term care,” she said, adding that the threshold for a person living alone in California is $20,121 per year.

While Medicare is available to adults over 65, subsidized aides are generally only provided after acute episodes, like hospitalizations, for fixed hours and for limited durations, she said.

“Most patients need to pay out-of-pocket and since cognitive impairment can last for decades, it is unsustainable for most people. Aides that are available via Medicaid are very poorly paid and usually receive limited training in caring for older adults with cognitive impairment,” she added.

In contrast, subsidized home care aides are generally available to a significantly larger percentage of their counterparts living in parts of Europe, Japan and Canada, said Portacolone, citing a 2021 review of 13 countries, of which she was the senior author.

The study’s findings illustrate substantial deficiencies in how our health system provides for people with dementia, said senior author Kenneth E. Covinsky, MD, MPH, of the UCSF Division of Geriatrics. “In an era when Medicare is going to spend millions of dollars for newly approved drugs with very marginal benefits, we need to remember that Medicare and other payers refuse to pay far less money to provide necessary supports for vulnerable people with dementia.”

The researchers advocate for a system in which robust supports are made available by funding from an expanded Medicare and Medicaid. This will become increasingly critical, said Portacolone, “because effective treatments to reverse the course of cognitive impairment are unavailable, childlessness and divorce are common, and older adults are projected to live longer and often alone.”
