How assistive technology can improve dementia care

Dementia is one of the most prominent challenges our society faces today. Indicative of the sheer scale of this challenge, dementia has been officially recognised as the ninth National Health Priority Area in 2012.

Dementia has already become the single greatest cause of disability in older Australians, aged 65 years or older. According to the Australian Institute of Health and Welfare (AIHW), the number of older Australians afflicted by dementia was estimated to be 322,000 last year.

But as the proportion of elderly people in our society grows at an unprecedented rate and life expectancy also increases, more and more people will be affected. Alarmingly, a 2012 report commissioned by Alzheimer’s Australia predicted that three million Australians will develop dementia between 2012 and 2050.

As the number of dementia sufferers rises, an adequately skilled and trained workforce will be required to ensure that complex, dynamic care and support services are delivered, thus placing further pressure on aged care providers.

One of the key responses to this emerging challenge has been the development of assistive technologies, designed to support people with dementia to live independently and safely for longer, as well as reducing the burden on their carers.

What is assistive technology?

Assistive technology is a broad term used to describe any item, object, device or system that enables a person to perform a task that they would otherwise be unable to do, or increase the ease and safety by which certain tasks can be performed.

Put simply, assistive technology is any aid that can assist the most frail and vulnerable members of our society to live safely and live well at home or in a residential care environment.

How can assistive technology help dementia sufferers?

The role of assistive technology and how it can be used to support someone living with dementia varies greatly. Assistive technology ranges from simple, standalone devices right through to complex, integrated systems that help a person to remain independent for as long as possible.

Some of the areas where assistive technology may help include everyday living, monitoring, safety, communication, as well as prompts and reminders.

Safety

Assistive technology for people with dementia is primarily designed to support security and safety, while providing a less intrusive living environment. For example, in a residential aged care setting, motion sensor technology can be used to silently alert staff when those residents with a high risk of falling move away from their chair or bed, in order to reduce the likelihood of falls and injuries. While in a person’s home, safeguarding technology can be used to protect against flooding, fires, intruders, the safe use of domestic appliances, and summoning help in an emergency situation.

Everyday living

Assistive technology can also be employed to assist with a person’s daily needs. These gadgets may include temperature sensors for automatic climate control, lamp and light activation, automated ovens, dishwashers and washing machines, automatic window and curtain controls, floor cleaning robots, garden sensors for automated watering, and electronic showers, taps and toilets.

Point-of-care technologies also enable remote monitoring of a person’s daily health condition such as blood sugar, blood pressure and heart rate. This data can be automatically transmitted to the appropriate health professional, who can monitor vital signs and make appropriate decisions about necessary interventions.

Monitoring

In instances where a person with dementia is prone to wandering and disorientation, assistive technology such as virtual door and exit sensors that detect entry and exit can be implemented to alert family members, loved ones and carers, while GPS tracking devices can securely monitor the person’s exact location to within metres.

Communication

Assistive technology that simplifies communication enables carers to be on-hand and assist when necessary, instead of providing round-the-clock, one-on-one supervision. As an example, video conferencing is now being used to facilitate communication with health professionals and service providers, which is particularly important where an elderly person may reside at a significant distance from the health clinic. In this context, assistive technology has the potential to relieve the pressure on caregivers and support their efforts in delivering care in a way that supports the independence of the resident or consumer.

But online communication can also help to address social isolation, which the World Health Organisation has identified as the single biggest ‘killer’ of older people and improve their health and wellbeing.

An example of this includes enabling older people to communicate with friends and relatives or participate in major family events via networked computers with internet capabilities. Access to internet applications, and online browsing, research, learning and games can also help broaden a person’s interests.

Prompts and reminders

The span of assistive technology also incorporates personal solutions that can positively impact confidence, health and wellbeing. Examples of these include automatic medication dispensers that help dementia sufferers to maintain medication compliance, while orientation clocks can help with confusion about the time, day of the week, month or year, and locator devices help to find lost items of property.

Benefits of assistive technology

It’s important to note that assistive technology is not about the technology. Instead, it is about enhancing a person’s quality of life through improved outcomes in safeguarding, living standards, social interaction and greater independence.

According the Victorian Government’s Dementia-Friendly Environments guide, the key benefits of assistive technology include:

  • allowing people with dementia make more decisions for themselves
  • offering safer and more secure living
  • giving people more privacy and dignity
  • reassuring family members about the level and quality of care
  • efficiency and cost effectiveness

A few concerns and considerations

One of the most common concerns about assistive technology is based around ethical issues – particularly devices that are used for monitoring safety, and how that may negatively impact the privacy or freedom of a person with dementia. Another common concern is that assistive technology may make life more complicated or extend beyond the abilities of the person with dementia. There is also the fear that these technologies may be used to reduce human contact and the services provided by carers. However, we firmly believe that as with all technology, assistive technology can be effective only when combined with high quality, consistent care and support.

When considering the use of technology to help with dementia care, the personal needs and choices of the individual are critical. It is no use trying to mould an individual to fit in with a certain technology. The proposed technology must be able to support and suit the individual and their unique situation.

Keep in mind that individuals will react differently to the various types of assistive technology. For example, one person might find it helpful to have a recorded message that prompts them to remember their keys or turn off the stove after use. But another person might find this confusing and intrusive. Therefore, prior to the implementation of any new technology, start by asking the following two questions:

1. Can the technology enable the person, carer or their family to do something that would not be possible without it?

2. Can the technology complement the care and support already being provided by carers in certain situations?

If the answer is ‘yes’, it is likely the proposed assistive technology would have a positive impact on the quality of a person’s life. For more information on assistive technologies that can help people with dementia live more independently, visit Alzheimer’s Australia.

    Nice articles. Technology can help seniors grow old at home instead of spending life in the old age homes.

    Part of my work is in the field of respite for carers and maintaining our clients’ independence at home. One piece of assistive technology much needed that keeps coming up in discussion with families, is an electronic diary built into an orientation device. Perhaps this already exists and I am unaware of the name it goes by. For instance a clock that can also have notes from family played at key points throughout the day such as ” I will see you tomorrow”, or “today the bus will pick you up for the Day Centre, mum. Your good shoes are in front of the mirror”. Or can it connect to an automatic phone call/skype that allows the family carer to give cues for ADLS such as dressing? I would appreciate an email back to let me know of any such device existing or in development.
