Underestimating a ‘Serious Problem’
The report “probably underestimates” the “serious problem with dementia specialty care in the United States,” David S. Knopman, MD, professor of neurology, Mayo Clinic, Rochester, Minnesota, told this news organization.
Given the complexity of managing treatments for AD, such as the monoclonal antibody lecanemab, or those for dementia with Lewy bodies, “my sense is that very few geriatricians are likely to take an active role in dementia care,” said Dr. Knopman.
Very few neurologists have specialty training in dementia diagnosis and care, he added, and neurologists who do specialize in dementia are generally located exclusively in tertiary medical centers.
“While neurologists are more likely to be able to diagnose dementia subtypes compared to geriatricians or general internists or family physicians, non-specialty neurologists are also unlikely to have the expertise to manage lecanemab therapy or to deal with diagnosis and management of dementia subtypes,” Dr. Knopman said.
“Filling the pipeline with new trainees is going to take a long, long time,” he added.
As it stands, most dementia diagnoses are not made by specialists. The report cited a study of Medicare beneficiaries that found 85% of people living with dementia were diagnosed by providers such as primary care physicians (PCPs).
Barriers to Care
Although screening is now a reimbursable service by Medicare, PCPs experience numerous barriers to detecting cognitive impairment and diagnosing dementia. Routinely used cognitive assessments are time-consuming and labor-intensive, making them challenging to use in a busy clinical setting.
“Even if dementia is diagnosed, providers sometimes wait to disclose this information to the patient due to diagnostic uncertainty, time constraints, stigma, and fear of causing emotional distress,” the authors wrote.
A previous survey by the Alzheimer’s Association uncovered a high degree of uncertainty and discomfort among PCPs in making a dementia diagnosis. While almost a third reported referring patients to specialists, 55% said there were not enough geriatricians and other specialists in their area to meet the demand.
In tackling the theme of dementia care navigation, the report included a survey of 1204 nonphysician healthcare workers, including nurses, physician assistants, and social workers.
About 60% believed the US healthcare system isn’t effectively helping patients and families navigate the system and that training in dementia care navigation is lacking and not standardized. Respondents also said nonmedical professionals are best suited to help people with dementia and their caregivers navigate care.
Respondents identified a range of barriers that make navigating dementia care difficult for patients and families. More than three in four (77%) identified a lack of community-based resources as a barrier. And 70% called out restrictions in current payment models as a barrier, with 41% saying this was the greatest barrier.
Alternative Model
In July, the Centers for Medicare & Medicaid Services will launch a pilot model in dementia care management, the Guiding an Improved Dementia Experience. The program will test a monthly per-patient payment model as a fee-for-service replacement.
Healthcare providers who participate in the program will deliver supportive services to people living with dementia and provide access to a care navigator to help patients and caregivers access services and support.
“There is growing momentum in this country to enhance dementia care navigation,” Dr. Fazio said in the release. “Dementia care navigation programs have shown they can be a huge benefit to people living with dementia and their caregivers.”
These programs are unfortunately not widespread across the country, but the Alzheimer’s Association hopes this report “will be a catalyst for change,” Dr. Fazio added.
A separate survey of dementia caregivers found they would overwhelmingly welcome navigator support. The vast majority (97%) said they would find navigation services helpful.
Such services may also go a long way to alleviating stresses involved in dementia caregiving, a top stressor being care coordination, the report noted. Seven in 10 caregiver survey respondents (70%) reported coordinating care is stressful. More than half (53%) said navigating healthcare is difficult, and two-thirds (66%) said they have difficulty finding resources and supports.
Around-the-clock support in addition to care coordination and help understanding their care recipient’s condition are among the top services dementia caregiver respondents cited as being most helpful.
Dr. Knopman reported no relevant conflicts of interest.
