Why hearing health matters for cognitive decline and dementia
In the latest guidelines published by the World Health Organization, hearing loss is recognized as the leading, modifiable trait in cognitive decline. Not only does it often lead to social isolation, depression, and withdrawal from regular activities, but when hearing becomes challenging, the brain needs to work harder to make sense of sound, drawing from cognitive resources used in key mechanisms like attention and memory. This is especially prevalent in adults over the age of 50; more than 60 per cent of older adults will develop hearing loss. But despite the glaring statistics, the Canadian health-care system has no clear structure or program to catch or address this prevalent need. The Infant Hearing Program aims to screen all newborns at birth, but after that most Canadians aren’t regularly tested or prompted to be screened for hearing loss at any other moment in their health journey. The responsibility often rests with individuals to identify hints of oncoming hearing loss and find a clinic where they can get tested; though because it develops slowly, it’s difficult for people to pinpoint and acknowledge. “What really ends up happening is that they’ll spend many years with hearing difficulties, withdrawing from activities, dealing with the fallout, before they reach the point of taking action,” said Bataineh. Many cases are left untreated. But hearing loss can be managed. Through interventions such as early screening, hearing aids and rehabilitation, people can maintain the communication they need to age well. It got Bataineh thinking: how could we better handle this condition, and how do we change the system to make it happen? Bolstered by a student initiative grant from Speech-Language & Audiology Canada, Bataineh envisioned a future where patients are routinely screened by primary care providers like family doctors and nurses, connecting them directly with audiologists. Not only could this catch hearing loss at its onset, it could lessen the load for busy physicians. This holistic model has been implemented with success in countries like the United Kingdom and Ireland, where integrating an audiologist directly into the primary care setting has relieved the caseload for family doctors. In Canada, there largely remains a disconnect between the two health fields. Most physicians and patients aren’t discussing hearing in appointments. If it does come up, it could turn into a months long wait to see an Ear, Nose and Throat (ENT) specialist or find a hearing test on their own. Beyond the challenge of getting to the right professional, audiology services are typically not covered by provincial health plans such as OHIP.Seeing the gap, and the critical need for a new way forward, she took it upon herself to try and make this vision a reality. Creating the Hearing Health Seminar Series, Bataineh reached out to primary care centres across the province, and set up lunchtime visits to present and discuss the importance of hearing well. Bringing along an audiologist to various sessions, Bataineh was able to spark direct conversations between hearing experts, physicians and clinic staff – from nurses to managers. “There’s not a lot of education or training for physicians on the topic of hearing loss. At the same time, in audiology we don’t have a full understanding of what they’re facing in the primary care setting,” she said. “These seminars open a two-way discussion where we each get to learn about the challenges we’re confronting and identify opportunities for collaboration.” The response was overwhelmingly positive. A slew of ideas for how to bridge the two fields quickly emerged. “Once people get together, it’s great to see the simple ideas that arise,” she said, from adding hearing checks to the electronic medical system or including hearing health in case history forms, so doctors are prompted to ask about it at regular checkups.“In order to stay on the world stage when it comes to health care, we want to make sure that our population is also getting access to these innovative models that streamline care.” – Jana Bataineh, PhD candidate in health and rehabilitation sciences
Connecting physicians and audiologists
The conversation didn’t end there. Through these sessions, audiologists and physicians had built a connection that turned into a referral pathway. Family doctors recognized the value in having a hearing expert they could connect patients to when necessary. One physician who attended the discussion, Dr. Omar Elsalakawy from Thompson Medical Centre, took the information to heart. “After the session, hearing loss started to become one of my regular questions, especially to older people who come in for a physical checkup,” Elsalakawy said.
