Thank you.
Madam Chair, honourable members, thank you for the opportunity to speak to you today regarding chronic diseases related to aging. I am very pleased to be able to speak on behalf of the Canadian Coalition for Seniors' Mental Health.
As a brief introduction, the CCSMH is a national coalition with approximately 3,000 members from coast to coast to coast, representing a full range of health disciplines, sectors, government and administrators, including older adults and caregivers themselves.
Our mission is to promote the mental health of seniors by connecting people, ideas, and resources. Our primary strategic goal is to ensure that seniors' mental health is recognized as a key Canadian health and wellness issue. With that goal in mind, I commend you for initiating your study on chronic diseases related to aging and for including mental illnesses in your definition of chronic disease.
As you are well aware, 2011 marks the year that the first baby boomers will turn 65, an important milestone for our aging population. Planning and foresight are required to ensure our systems and structures adjust to best accommodate this demographic shift and to ensure we don't buy into apocalyptic demography or the oversimplified notion that population aging will have catastrophic consequences for our society.
Recently I had the pleasure of co-authoring new guidelines for comprehensive mental health services for older adults in Canada. Copies of these guidelines are on USB keys that I think have been distributed. These were funded and published by the Mental Health Commission of Canada. Within these guidelines we clearly outlined four distinct populations living with mental illnesses in later life, populations that I hope you'll keep in mind as you continue your study on chronic diseases. They include those growing older with a recurrent, persistent, or chronic mental illness; those experiencing late mental illness for the first time in late life; those living with behavioural and psychological symptoms associated with Alzheimer's disease and related dementias; and those living with chronic medical problems with known correlations with mental illness, for example, Parkinson's disease, cerebrovascular disease, and chronic obstructive lung disease.
As outlined in the Chief Public Health Officer's report on the state of public health last year, in 2009 chronic conditions were widespread among seniors, with 89% living with at least one chronic condition and many experiencing multiple chronic conditions. One in four seniors aged 65 to 79 years and more than one in three of those aged 80 and older reported having at least four chronic conditions, including arthritis, high blood pressure, diabetes, heart disease, cancer or stroke, Alzheimer's disease, and mood and anxiety disorders.
I will remind you that many of the common chronic illnesses of late life have known correlations with mental illness. For example, major depression occurs in about 40% of patients who have experienced an acute stroke. As outlined in the recent Alzheimer Society of Canada report, “Rising Tide”, we also know that the number of new cases of dementia in 2038 among Canadians aged 65 plus will be 2.5 times the number in 2008, with a projected incidence of 257,811 new dementia cases per year by the year 2038.
Comorbidities make accurate diagnosis of mental illnesses much more challenging. Untangling the symptoms of physical illnesses from somatic presentations of mental illnesses such as depression can be difficult, and without proper training, health care providers can and unfortunately do let treatable illnesses go unnoticed. Health outcomes can also be negatively impacted by an untreated depression, as indicated by a recent report from the Canadian Institute for Health Information, suggesting that residents of long-term or residential care homes who are diagnosed and treated for depression have better health outcomes than do those who are not.
I'd also like to highlight that despite the chronic and sometimes progressive nature of all of these common mental disorders in late life, there are successful treatment options and strategies to promote recovery and well-being, and despite the fact that some, such as Alzheimer's disease, currently have no cure, we can move towards recovery and well-being. Additionally, primary, secondary, and tertiary prevention strategies can be employed to reduce occurrence and severity of symptoms as well as medical comorbidities. Older adults who are on a journey towards recovery and well-being are important contributors to our society. They are valued as volunteers, as caregivers and social supports to family, friends, and community, and they are an investment worth making.
As you are likely aware, the UN summit on non-communicable diseases, held in New York this September, highlighted the need to recognize that mental and neurological disorders, including Alzheimer's disease, are important causes of morbidity and contribute to the global NCD burden.
These priorities are also reinforced by the World Health Organization's statistics, indicating that by the year 2020, depression is projected to reach second place of the ranking of disability-adjusted life years for the sum of years of potential life lost to premature mortality and the years of productive life lost due to disability, calculated for all ages and both sexes.
And of course the most tragic complication of depression is death by suicide. I again would like to commend your committee for the recent discussions in the House of Commons about the need for a suicide prevention strategy in Canada, and also take this opportunity to remind you that older adults are not immune from suicide. In fact, according to the 2008 Statistics Canada data, men aged 90 and older have the highest rates of suicide in Canada, just under double the national average, with a suicide rate of 33.1 per 100,000 population, compared with the overall rate of 16.8.
And for the context of your study, you should consider that research by Heisel and Flett, published in 2005, indicated that mental illnesses and medical illnesses such as chronic lung disease, neurological disorders, moderate or severe pain, and cancer are some of the risk factors for suicide among older adults.
We currently live in an acute care system, despite the compression of morbidity we see in late life. So what can be done? I would like to suggest several action items for the consideration of this committee. When discussing chronic diseases related to aging, I would encourage you to approach this topic within a social ecological model, with consideration of intra- and interpersonal factors and processes, institutional and community factors, and public policy. The model predicts that efforts focused exclusively on the individual at the expense of other factors are likely to fail, and thus efforts to improve an individual's health should be directed at multiple levels simultaneously.
I would also suggest that the life course theoretical model be used as a lens for considering chronic disease and aging. This theory is a necessary vehicle to look at the older adults in the context of time and social structures, and it has influenced a body of research on social inequalities and how these inequalities tend to become pronounced as a person ages—the notion of accumulated disadvantages.
I would also urge you to look beyond academic literature and to value evidence informed by people with lived experience and their caregivers when looking for interventions to improve the lives of people aging with chronic diseases. One such example is the philosophy of self-management, which empowers older adults and their caregivers to be active and engaged partners in their health care and disease management.
I'd also ask that you consider a functional approach to health, where we consider people of all ages and their ability to interact in the world rather than labelling people by their diagnoses. As eloquently stated by my colleague, Dr. Elaine Wiersma, chronic disease prevention and management is often disease focused and should be life and person focused.
I would also urge you to work with partners such as the Mental Health Commission of Canada to implement strategies that address the stigma that may prevent older adults from accessing services and/or may lead to the improper assumption that some of their struggles are attributed as just being a part of growing older rather than illnesses that can be addressed. I would also remind you that for those older adults living with mental illnesses, they face the double whammy of stigma, both of ageism and the all too common stigma associated with mental illness.
In closing, it is my belief that the federal government can play a crucial role in the issue of chronic diseases related to aging, despite provincial jurisdictions over health. As we approach the renewal of the health accord, I urge you to consider some of the recommendations made in the 2009 Senate report on aging, including:
To provide leadership and coordination for multijurisdictional approaches to addressing the needs of our aging population;
To provide support for research, education and the dissemination of knowledge and best practices;
And finally:
That the federal government develop a federal initiative which would provide financial support to the provinces to facilitate the move toward integrated models of care for the elderly as a model for quality care for all ages.
I'd like to thank you again for this opportunity, and I look forward to ongoing dialogue in the future.
