How Can We Design Assistive Technology that Helps People with Early-Onset Dementia?

Posted in research at 9:18 am by mariawolters

Living with dementia can be hard for the person with dementia and for the people who care for them. Good support can make life a lot easier, and create space for moments of contentment, joy, and happiness.

In the past decades, assistive technology developers have sought to provide part of this support through specialized technology. Just as a prosthetic leg can help amputees walk, developers have created prosthetic memory solutions that fill the gaps in a person’s own memory.

However, finding the package of solutions and services that is best for the person with dementia and their carers can be very difficult. Often, these services are put together by occupational therapists.

In the paper I am discussing here, three occupational therapists, academics and practitioners from the North of Norway, Cathrine Arntzen, Torhild Holte, and Rita Jentoft, reflect on the process of creating a technology solution that works. They focus on people who are diagnosed with dementia relatively early in their lives, in their fifties and sixties. These are baby boomers who tend to be far more familiar with technology than people in their eighties and nineties, who are more likely to be diagnosed with dementia.

To give you an idea of the complexity of these solutions, the assistive technology introduced, which is documented in Table 1 of the paper, ranged from a simple digital calendars to a package of four devices, and included specialized solutions such as a reminder connected to the timer of the coffee machine and non-technological solutions such as whiteboards.

Methodology

For their study, they used a longitudinal, qualitative design. This means  that they followed 12 people and their carers for a year after the first home visit, when their needs were assessed. They talked to their participants every three months, reviewing issues that had come up at past interviews, and exploring new issues that had arisen. They also took notes of their own observations.

Qualitative data such as interviews are notoriously difficult to analyse. Each analyst approaches the text with their own preconceptions and ideas. Therefore, texts are often analysed by two to three people over several iterations, comparing and contrasting their findings, to ensure that their interpretation is grounded in what the participants told them.

As a result of analysis, patterns and themes emerge as well as individual experiences that highlight wider issues. There are many ways to ensure that these findings can be useful in different contexts. In this study, Arntzen, Holthe, and Jentoft interpreted their findings in light of a particular theory of lived experience, phenomenology.

Findings

Arntzen, Holte, and Jentoft identified five elements of a successful assistive technology. As I list them, I will comment on each from my own experience of working in this field.

1 The technology has to address an actual need, which can be practical, emotional, or about the way people relate to each other.

Comment: This means that careful initial assessment is important, and default packages are likely to fail.

2 The technology has to fit in with people’s established habits and problem solving strategies, because they reflect how a person thinks about and relates to the world.

Comment: If a piece of assistive technology is introduced because it provides useful data to central services, even though it would require people with dementia and their carers to rethink the way they organize their lives, it is highly likely to fail.

3 The technology needs to be reliable and trustworthy, and people need to feel good about it.

Comment: This means that assistive technology needs to be well designed and tested, requiring high quality software engineering, and supported by qualified engineers who can intervene quickly in case of malfunctions.

4 The technology needs to be user friendly, adaptable, and easy to manage.

Comment: Ideally, all technology would be like that, but all too often, technology is designed primarily to provide data and to enforce standard procedures, and to enforce a predictable life with no room for spontaneity. This has been a problem for a long time, and it is a typical of the conflicts between stakeholders (people with dementia who want to live their own lives as they used to; carers; social care; health care; policy)

5 The technology needs to interest and engage the family carer. It is likely that the family carer will be the one to look after the technology, keep it up to date, make sure it works, and use the more complex functionalities. If they like it, and if it engages them, it is more likely to be used. A case in point was the digital calendar, which proved very popular with the carers, less so with the people with dementia.

Comment: Family carers are sometimes overlooked in the work on supporting people with dementia to live in the community, as there is a strong emphasis on helping those who do not have family live independently – those are the people who require more social care time. Carers are also often assumed to be children, and spouses are assumed to be technophobic, as they are older. However, all of the people with dementia in this study were cared for by their spouse, who was in a similar age group. This means that we need to make sure technology for people with dementia is also accessible to older people without cognitive impairment.

Conclusion

While much  of what Arnzten, Holthe, and Jentoft found in their paper will not be new to people who work in the field, I still think that their paper is a salutary reminder of just how important adaptable, flexible technology solutions are. Fixed packages of standard technology may be easier to maintain and to prescribe, but will they pay for themselves in actual daily use? If Arntzen, Holthe, and Jantoft are right, then this is highly unlikely.
