Electronic tags were one of several restrictions imposed under the now defunct control orders

Does electronic surveillance of persons with dementia conflict with personhood?

Families, friends, and carers of people with dementia may be faced at some time with the problem of what to do if the person begins to wander. Wandering is quite common amongst people with dementia, and can be very worrying for those concerned for their safety and living well. The problem of wandering in dementia is not trivial. It causes stress to carers, referrals to psychiatric services and hospital admissions, problems in the hospital environment, and an unknown number of deaths.

The last Labour government developed a reputation for being authoritarian in the domain of civil liberties, reaching a peak, arguably, with its legislation for terrorists for detention without trial. Governments of all shades have at some point or other wished to stamp their liberal or libertarian credentials, and indeed in relation to the free market. For example, an outsourcing company within the lifetime of this government got into trouble over allegations to do with prisoner tagging.

Different companies have been pitching their products – tiny cameras, wearable sensors, connectivity services – mainly at the US and other rich countries where abductions and violent crime are mercifully rare. Google recently, to much media attention, launched with great fanfare its ‘Google glasses’. Indeed, a Scottish friend of mine recently logged onto her Facebook in Bilbao in Spain, and Facebook cunningly producing a sponsored advert for a hotel in Bilboa. When you make a tweet, you have an option of activating the ‘location detector’ of your tweet. This article is not about terrorism or the use of smart apps to book hotels, but the point is merely that a plethora of converging evidence might suggest that a technology explosion may be going hand in hand with a surveillance culture, and it is perhaps no big surprise that this is also having an effect on dementia care.

I asked Alex Andreou, who has written with remarkable authority and passion about his own mother living with dementia in the Guardian newspaper, what he thought of the general issue of electronic surveillance of persons with dementia?

“I would welcome it. Terrifying when I see reports about people lost.”

When I reassured Alex that I would not mention this name, Alex said, “I don’t mind if you do.”

Sussex Police has been trialling the scheme at a cost of £400 a month, and hopes it will save the force thousands of pounds by avoiding call-outs which can take up a lot of police officers’ time and can involve the use of search helicopters. A number of local authorities are already using similar devices to track sufferers, but this is believed to be the first time a police force has taken on such a scheme in May 2013. If the trial is successful, there are ambitions to roll it out across the county to a much larger population. The idea is that people with dementia can wear the tracking device around their neck, clipped to a belt or on a set of house keys. It works through a Global Positioning System (GPS) – a space-based satellite navigation system that is used by ‘sat-navs’ in vehicles. It is linked to a 24/7 response service which the wearer can call at a press of a button. The device is called “MindMe”, and family and friends can log into the system whenever they like to find out where the person is.

It is claimed that the Police regularly have to search for missing people with dementia, and that it is genuinely heartbreaking to see the torment that their families are put through and to see the impact it has on the person with dementia when they are found. A £15 (€18; $23) pair of transmitters would, for example, sound an alarm if the person gets separated. GPS trackers not intended as a general panacea, but they do mean that patients can be found more quickly. This is thought to be useful for several reasons. Firstly, rapid recovery reduces risk. Typically, carers delay calling for help, wanting to avoid involving the police if possible. Half of all people with dementia who are missing for more than 24 hours can die or become seriously injured. However, 40% of those with dementia get lost at some point, and about 5% get lost repeatedly. It is this 5% who are the most obvious candidates for a tracker. The first episode of getting lost is usually not predicted, and is often followed by restrictions on freedom and increased observation, reducing the perceived need for a device.

On November 11th 2013, Norman McNamara, a campaigner for awareness of the dementias himself who himself is living with a dementia, announced that, that Ostrich Care would be making available free GPS trackers to all persons who are diagnosed with dementia, and to registered carers (in the UK, not uniquely to the Torbay area.) A monthly ‘maintenance fee’ still has been made though. The info from Ostrich Care is here (ht: Jane Moore).

But in reality there is no right answer. The situation is complex. Decisions about limiting a person’s liberty should remain a matter of ethical concern even when technology finally makes the practical management of wandering easier. This approach has as its backdrop evolving body of work on technology and dementia, known as “assistive technology”, where collaboration and engagement with “users” has been a guiding principle. The earlier literature on electronic surveillance monitoring pointed out that the technique could be associated with objectification, infantilisation, and disempowerment, which are negative phenomena. The acceptability of surveillance monitoring has generally been researched among formal and informal carers only, with the views of those living with dementia curiously under-represented.

The whole issue can raise strong emotions. Dot Gibson, general secretary of the National Pensioners Convention, has been reported as feeling that the Sussex Police scheme is “inhumane”, “barbaric” and flouts fundamental  human rights. This criticism has been bundled with a general criticism of the care system, with Gibson adding,  “This is trying to solve a human problem with technology”.

According to Gibson:

“Using electronic tags on dementia sufferers raises very important issues about the individual’s human rights. They haven’t committed any crime – they’ve just grown old. This is just about saving money rather than treating people with dignity. Rather than tagging people we need better social care out in the community. Dementia patients need human interaction not tagging.”

In terms of medical ethics, “autonomy” relates to self governance or personal control. One of the main aims of implementing these surveillance monitoring devices is the promotion of increased independence. Most carers, whether relatives or paid staff, want the best for the person they support. Alongside doctors’ duties of beneficence, non-maleficence, and justice, respect for patient autonomy is invoked as a cardinal principle. The legal courts in various jurisdictions have confirmed the principle of respect for patient autonomy in the language of rights of self-determination. This is not merely viewed as a a rejection of a paternalistic tradition of ‘doctor knows best’, but includes differing philosophical positions including those of Kant.

There are a number of possible reasons why a person with dementia might wander, and this is related to which parts of the mind or brain are affected at any particular time. Here is yet another example where it is unhelpful to think of ‘dementia’ as one big homogeneous group. There are hundreds of different causes of dementia, and this might impact on why a person with dementia wanders. However, any patient living with dementia can of course become acutely confused, just like any other person (particularly in the elderly age group due to some underlying infection, for example.) Various important causes include a changed environment, excess energy, searching for the past, expressions of boredom, where it might be difficult to establish an underlying ‘medical cause’.

Dementia of the Alzheimer type is the most common type of dementia worldwide. Memory problems are the hallmark of dementia of Alzheimer type. Indeed, wandering may be due to a loss of short-tem memory. A person may set off to go to the shop or a friend’s house, and then forget where they were going or why. Or they forget that their partner has told them that they were going out for a while and set off in search of them. In another type of dementia known as Lewy Body dementia, visual hallucinations can occur: in other words, seeing things which aren’t there. An inability to distinguish hallucinations from reality may cause the person to respond to something that they dreamed, thinking that this has happened in real life. Lewy Body dementia tends to affect the younger age group (by younger, I mean below the age of 60).

In advanced dementia, whatever the cause of dementia, people can lose their regular ‘body clock’ or circadian rhythm. People with dementia may suffer from insomnia, or wake in the early hours and become disoriented. They may think it is daytime and decide to go for a walk. Poor eyesight or hearing loss may mean shadows or night sounds become confusing and distressing. Also, in advanced dementia, walking may actually ease discomfort, so it is important to find out if there is any physical problem or medical condition and try to deal with it. Tight clothing, excessive heat or needing to find a toilet can all cause problems. Also, changes that have occurred in the brain may cause a feeling of restlessness and anxiety. Agitation can cause some people to pace up and down or to wander off with no apparent purpose. They may fail to recognise their own home, and insist on leaving.

Some caregivers appear to like the idea of electronic tracking devices if these can ensure that the wanderer is found more swiftly. Some argue that for, the sake of safety, a slight loss of liberty might be a price worth paying. In the case of someone with moderate to severe dementia who wanders, electronic surveillance monitoring arguably satisfies an ethical principle and decreases stigma. Being lost and half dressed in the middle of the night near a dual carriageway to any reasonable unlooker is hugely stigmatising, and electronic surveillance monitoring could avoid this. However, there is a concern that wandering as a behaviour of the dementias, like many aspects, is generally becoming overly medicalised, or turned into a medical problem. The inevitability of this is to turn it into a medical problem in need of a medical solution. This in turn potentially legitimates social control efforts in the name of ‘protecting’ wanderers.

Social control through the medical gaze encourages an environment of pharmacological surveillance and physical confinement. We all know of the dangers of the approach of the “chemical cosh”. Neuroleptic drugs have harmful side effects and show only modest efficacy in managing some behavioural problems in dementia. Physical restraints, such as safety belts and bedrails, are used in nursing homes all over the world, with a prevalence somewhere averaging around 50%. There is growing awareness that the use of these means can have significant psychological and physical disadvantages, such as increased cognitive decline and decreased mobility and has even led to death in some cases. Therefore, it is argued legitimately that the use of physical restraints should be diminished. Counsel and Care’s famous publication ‘The Right to Take Risks’ (1993) lists at least twenty forms of restraint commonly used at present, ranging from literally tying someone down to the use of sedatives, locks, glass panels in doors, threats and poverty. Despite the negative press associated with electronic surveillance monitoring devices in some quarters then, this new technology, developed and perfected as a result of its uses in prisoner tagging, may offer somehope of a more humane solution to a difficult problem. Here, language is crucial, as “surveillance monitoring” is a preferable term to “tagging”, as it is completely objectionable to use language for people with dementia normally reserved for criminals. You cannot be ‘convicted’ of having a diagnosis of dementia. Whilst some ideologically might feel nervous of a somewhat libertarian-facing solution, the risks and restrictions of alternatives to surveillance monitoring, should perhaps be borne in mind.

Over the last decade, a new ethos in the management of wandering has evolved with a move towards promotion of safe walking, rather than the prevention of wandering, in order to balance a person with dementia’s need for autonomy with the need to minimise risk. Other non-pharmacological approaches include: behavioural approaches; carer interventions; exercise; music therapy; sensory therapies (aromatherapy, multi-sensory environment); environmental designs and subjective barriers (visual modifications that may be interpreted as a barrier but are not physically so). Evidence on the effectiveness and acceptability of the above interventions is limited. The availability of all alternatives will frequently depend on resources, attitudes and policies of health professionals, institutions and governments, and the precise legislative and regulatory framework.  For example, in the Netherlands, the Health Care Inspectorate promotes the use of surveillance technology as a way to diminish the use of more severe means of restricting freedom. In 2009, already 91% of the nursing homes were using some kind of surveillance technology in the care for people with dementia. In most developed countries, the legislation regarding the use of physical restraints is based on, among other things, guidelines of the United Nations and the World Health Organization and the European Convention on Human Rights (Council of Europe, 1950; General Assembly of the United Nations, 1948; World Health Organization, 2005).

Although surveillance monitoring might increase liberty in some senses, it has the potential to decrease autonomy and tracking devices might settle the anxieties of others without attending to the needs of the person with dementia. There are considerations from medical law and medical ethics too on the place of the family. Where the adult patient is unable to consent, both medical ethics and law allow for consultation with relatives. Indeed, consultation with the family is the default position in cases of adult patient incompetence. The general tradition of ethics can be denoted through primary concern with individuals; in fact, medicine’s traditions have a tendency to be individualistic. It could be that ‘taking friends and families seriously’ challenges that individualistic approach. For illustration, the doctor-patient relationship is structured in a manner similar to a contract between two individuals, and the doctor has a duty to the person/patient. Contrary to individualist perceptions of autonomy, “communitarians” acknowledge the significance of the person’s relations. This is of course particularly relevant if one wishes to pursue in English policy and elsewhere the notion of “dementia friendly communities”. If it can be mooted that liberals focus on what separates people from one another, communitarians see persons as fundamentally attached to each other. For such an approach to work, those advising concerned relatives need to be trained in not only dementia care but also in understanding and negotiating the different ethical perspectives of carers and professionals.

This is important so that professionals do not seem to be assume some high moral ground of civil libertarianism, as well as to allow recognition that our autonomy is exercised in the embrace of others. So in my opinion the use of surveillance technology, as either an infringement of human rights or as contrary to human dignity, as it reduces or infringes privacy and removes personhood, is only a small part of the issue. There is a danger that resorting to technology in general might result in a reduction in the essential human contact between caregivers and residents and could lead to a further decrease in staff in long-term care facilities. However, if this is a known risk, this can be mitigated against, and adoption of electronic surveillance monitoring might led to the evolution of a more secure environment (thereby reducing caregiver stress), but also increase liberty and dignity when compared with forms of physical restraint. The ‘threat to personhood’ is an important consideration, and the law itself regarding mental capacity as currently drafted in the English jurisdiction could indeed be too a blunt weapon. However, policy in general has been driving to empowering persons with dementia to have more choice and control than previously, and this policy driver is not at all insignificant.

  • Excellent article covering some very important issues.

    Some value in raising awareness and talking about available assistive technology in early stages.

    AS has a policy statement on Safer Walking Technology (http://bit.ly/1hUGcZC) which is helpful. SCIE (http://bit.ly/OwUpyO) & JIT Scotland (http://bit.ly/SkrLjt) have also done some useful work on ethical issues of assistive technology/telecare.

    Looking forwards to the publication on 17 January 2014.

    Well using electronic surveillance on dementia or Alzheimer’s patient is always a violation of human rights as it limits you in some kind of boundary and since you are mature enough to take your decision on your own, tagging dementia patient with electronic surveillance is not a right move to implement, there are many other options to take care of dementia patient like home care and home help services, moreover a dementia patient need a good emotional support from their family and friends to survive and recover from dementia.
