I am delighted to have the opportunity to present some of the insights from the IDS-TILDA study and, briefly, The Irish Longitudinal Study on Ageing for people with intellectual disability. I hope this will help to inform important deliberations.
IDS-TILDA examines ageing among people with an intellectual disability aged 40 years and over in the Republic of Ireland. It is the first study of its kind in Europe, and the only study in the world with the ability to compare ageing in the general population with data yielded by TILDA. The study commenced in 2008 and one of its key strengths is its ability to track initiatives and reforms intended to support change in the lives of people with an intellectual disability. We have seen that there has been a number of important achievements during this period. Our first report, in wave 1 in 2008, reported that 47% of participants lived in residential or congregated settings. By wave 5, in the overall population this figure had reduced to 28.5%. The change was even more dramatic when we looked at those aged 40 to 50 years. In wave 1, almost 45% of participants in this age category lived in residential or congregated settings. By wave 5, this had dropped to 7.7%. Our data supports that continuing to deliver on movement to and engagement in the community must continue to be a key priority. We have found that quality of life is lower for people living in congregated settings than those living in the community and those living in the community are less likely to have choice and self-agency across many life domains. We are aware that around 2,000 people continue to live in congregated settings so we need to continue to work on that.
We have found increases, as compared with wave 1, in the proportion of participants who had regular contact with both their family and friends, more people living full social lives with rich interpersonal relationships and engaged in their communities. Again, the most notable increases were among those less than 50 years of age, those with mild intellectual disability and those living in the community.
This is good news but many barriers and concerns remain. People with more severe intellectual disabilities, those living in residential or congregated settings, remain dependent on staff for support. Staff are really important in their lives. There is a huge crisis in the recruitment and retention of staff. This is a major issue in terms of the security and well-being of many people with severe to profound intellectual disability.
Approximately 20% of participants reported not leaving their house at all. For some, this was a personal choice. However, others - one in five in this group - reported this was due to a lack of staff or resources to get out of their home.
The findings of IDS-TILDA continue to highlight high rates of often manageable or preventable physical health problems, including chronic constipation in about 50% of this population, high levels of poor bone health, for example, osteoporosis which is often undiagnosed, and a high incidence of falls and fractures, all of which we know impact hugely on quality of life and increased risk of mortality.
Medication use remains higher, with patterns of prescribing substantially different from those observed in the older population by TILDA. Although we have seen a decrease over time in the use of some medications, particularly in those under 50 years, overall levels of polypharmacy and hyper-polypharmacy, which is the use of ten or more drugs, at 21%, are much higher than in the general population, at 2%.
IDS-TILDA is also shining a light on poorly understood diseases in areas such as oral health, women’s health and cancer. Cancer was infrequently diagnosed across the five waves, yet it was one of the leading causes of death recorded on death certificates. We are not identifying cancers in a timely manner, which would offer people with intellectual disabilities the opportunity to avail of new therapeutics and treatments. There is also a limited understanding of their experience of survivorship.
We have also shown that women with an intellectual disability die, on average, 20 years earlier than women in the general population and they have much poorer levels of physical and mental health. Menopause occurs at an earlier age and, indeed, earlier again for women with Down's syndrome, yet many were unaware of menopausal transition. Very few had spoken to anybody about this and over 80% of them did not receive information they could readily understand. This is an area that really needs to be examined.
The IDS-TILDA study on oral health revealed stark inequalities, with high rates of oral health disease and a lack of access to essential dental care. Two in five participants aged over 65 were edentulous, which means they had no teeth at all. This rate far exceeds the rate in the general population. Of those without teeth, 70% lacked dentures compared with 5% in the general population, so they were orally disabled. Over 70% lacked functional dentition, affecting smiling and their ability to eat and chew food. Oral disease was prevalent, with nearly half of participants having cavities, two thirds experiencing swollen gums and only a quarter having clean mouths. Dental anxiety was high and although most had seen a dentist recently, these visits were often for assessment without treatment.
There is a fivefold increased risk of people with intellectual disability, particularly those with Down's syndrome, developing dementia compared with the general population. We know that for people with Down's syndrome aged over 65, the risk of developing dementia is almost 80%. This compares with a risk of between 4.8% and 8.6% among those aged 65 years and older in the general population. The risks are, therefore, very different.
IDS-TILDA, when it comes to translation, has driven the model of dementia care in Ireland with the establishment of the national intellectual disability memory clinic, which gives everyone in Ireland a chance to access memory screening, assessment and post-diagnostic advice. I acknowledge the Minister of State at the Department of Health, Deputy Mary Butler, and the national dementia office for listening to the advice, taking it on and building a world-class memory clinic at Tallaght University Hospital.
We are working hard on areas like brain health. We must tackle things like brain health and create prevention programmes. We are positioned to engage in much-needed clinical trials for this increasingly at-risk group in our population.
More generally, our health findings support an approach that focuses on diagnosis and prevention: health promotion; the creation of care pathways and capacity building within mainstream health services; and the creation of disability-friendly hospitals and healthcare environments that truly understand and embrace what reasonable adjustments look and feel like. This will benefit not only people ageing with an intellectual disability but everyone in society. Failing to adopt such an approach may result for many in a return prematurely to institutional care and the congregated settings they have left or, even more concerning, a move into long-stay nursing homes which are often ill-suited to meet their needs due to a lack of disability-specific knowledge and training among staff. We have demonstrated this trend, with lack of resources, increasing costs and lack of capacity among the workforce, as the key driver to transfer to more supported settings.
IDS-TILDA has also been examining how the family caregiving landscape in Ireland has continued to change.
Decongregation and an increased reliance on family caregivers are challenged by smaller family sizes and the progressing age of parent carers, people with intellectual disabilities and, to some extent, siblings, of whom we have seen many. This raises serious questions regarding the sustainability of care for older people with intellectual disabilities in the coming decades.
For participants in the IDS-TILDA caregivers' study, we have seen a growing generational transfer of care from parents to siblings, but many of those siblings said they were the last remnant of care and that they would not transfer that care responsibility to their family members. Although most carers strongly agreed or agreed that providing care made them feel needed, feel useful and appreciate life more, they frequently cited being constantly on call and the stress and emotional strain as difficult. Many found the role confining and expected to be still providing at least the same level of care in five years, and many of them were in their 70s or 80s. Carers expressed a lack of confidence that the State would look after their adult family member when they themselves could no longer do so. Carers’ allowances and respite services were acknowledged as helpful, but there is not a comprehensive set of supports needed for caring to continue, nor are alternatives available when caring cannot be sustained in the family home.
IDS-TILDA demonstrates that the lives of people with intellectual disabilities have improved, sometimes dramatically, especially in younger age cohorts. This is particularly true for those with mild and moderate levels of intellectual disability, but not so for those with a severe intellectual disability nor for those living in residential care. Much more work is needed, particularly to address preventable and treatable mortality. IDS-TILDA is documenting the changes in lives and continuing challenges in ways that no other survey can or does. We now have the strongest data in the world on the physical and social determinants of health and well-being for people with intellectual disabilities as they age. Let us use it wisely to inform policy and the necessary supports to ensure people with intellectual disabilities can age with dignity and pride.
I hope we have learned from the history of our past, a past when people with intellectual disabilities were segregated from their communities. We must not give up on the hard-fought gains we have made within the disability sector. A premature return to institutional care is a serious breach of Article 19 of the UN Convention on the Rights of Persons with Disabilities. Instead, our focus should be driven by the belief our work with people with intellectual disabilities is about not just adding years to life but equally, and critically, adding life to years.
We are grateful for the support we have received from the Minister of State, Deputy Rabbitte, as well as from previous Ministers and various Departments, the Health Research Board, the HSE clinical leads and the National Federation of Voluntary Service Providers, with which we so work so closely. Most critically, people with intellectual disabilities themselves have shaped our understanding of their ageing.
