Many of us pay close attention to how our taxes are spent, and how well governments invest in infrastructure projects such as roads, schools and hospitals. Value for money is key. Yet horror stories of waste, lateness and poor quality are common.

To develop and finance public services and infrastructure, governments around the world (but especially in Europe) have become increasingly keen on private sector involvement. These cross-sector collaborations can help provide value for money for taxpayers – but they are also at risk of wasting it.

In health care, collaborations between public and private partners have a direct impact on society. This is why it is important for health care professionals like doctors and nurses to talk directly to the designers and builders of a new hospital. It ensures that these projects not only deliver economic value for the private companies building the hospital – but also social value for the doctors, nurses and patients who will use the hospital for decades to come.

For instance, in one recently built British hospital, medical staff were able to bring valuable insight to the design process. A visit by some of the hospital’s senior nurses to a children’s hospital in the US led to the replication of a lighting design on the ceiling of a children’s ward so that it mimicked a starry night sky. As one of the nurses explained to me afterwards:

It might sound like a small change, but it provides a much more homely surrounding than the normal NHS lighting. This is important for our young patients [providing a] less scary, hospital experience which positively impacts on the healing process. […] It creates a much nicer environment in which our little patients can recover.

In another hospital, input from senior nurses helped to establish a ward design that most suited their professional needs – right down to the placement of plumbing. This saved large amounts of money that might have been spent on undoing unnecessary building work had the nurses not been consulted.

As one project manager of the construction company told me: “Thanks to [the senior nurses’] input and telling us how they intend to use wards, we changed the ward layout, such as the position of sinks. This may seem to be a minor issue, but may have a huge impact when caring for a patient.”

To see how social value can be best achieved through cross-sector collaborations we looked into the key building blocks that go beyond a mere focus on contracts.

An organisations’ prior experience of cross sector collaboration and a supportive climate is vital in creating social value. It also helps to have had some exposure to previous projects (good and bad). But a major ingredient is the individual employees in both public and private sector organisations.

We need a starry sky ceiling right there.

Building mutual knowledge and aligning goals between doctors, nurses and design and construction professionals is key, as public and private sector employees often have different objectives for projects (making a profit vs healing patients). A shared understanding can come through listening to and appreciating the other parties’ professional language and the expertise that language expresses.

Joint expertise

Beyond an understanding of the other parties’ expertise, practical matters of shared goals and jointly developed timelines are necessary. Coordinating efforts between the two sectors needs to take priority at the outset – rather than emphasising project speed and completion.

To encourage these positive outcomes, the key people need to meet frequently to exchange information, address problems and discuss plans. Without this kind of coordination and collaboration, it will be impossible to make the most of both sides’ specialist knowledge.

So when it comes to hospitals and clinics, the private company needs to actively seek the involvement of doctors and nurses in the design and construction phases. Similarly, doctors and nurses should not be threatened by private companies, but instead seek to become actively engaged. This will help drive creative design innovations such as the “night sky” ceiling in the children’s ward.

The ConversationIt takes time and resources, but this kind of collaboration and coordination between public and private sectors provides an opportunity to increase value – both economic and social. And that’s something that not only benefits construction companies and health care professionals – but patients and taxpayers, too.

A new study out today has found residents with dementia in aged-care facilities that provide a home-like model of care have a better quality of life and fewer hospitalisations than those living in more standard facilities. We also found the benefits of a home-like model were provided without an increase in running costs.

Our study compared home-like models (which have up to 15 residents per unit and free access to outdoor areas) to more standard residential care, where a large number of people are housed in one building. In 2011, around half of all facilities in Australia had places for more than 60 residents, and the average size is growing.

The World Health Organisation has stated smaller home-like residential care settings “hold promise for older people, family members and volunteers who provide care and support”. But Australia is lagging behind other countries in offering alternative models of residential aged care.

There’s no need to lock older people into nursing homes ‘for their own safety’


What is a home-like model of care?

Most older people with dementia want to stay at home as long as they can. When this is no longer possible, they move into residential aged-care facilities, which become their homes.

These residential facilities, or nursing homes, frequently adopt a model of care that emphasises individuality. This is known as person-centred care. But delivering this model may require more staff or a different mix of staff, which may be difficult to deliver with current funding.

So standard aged-care facilities in Australia often have some similarities to health facilities, with designated staff areas and centralised kitchens. Access to outdoor areas, particularly for people with dementia, may depend on the availability of staff. Despite adhering to philosophies such as person-centred care, the scheduling of this care and of meals often lacks flexibility.

The problems are compounded when residential care is used for multiple purposes ranging from palliative care to providing care for people with dementia. The needs of these two groups are quite different and the lack of focus makes delivering quality care a challenge.

Evidence shows the physical design of the residential aged-care environment may play an important role in the well-being of residents, particularly those living with dementia. Internationally, there is a move towards providing care in facilities that feel more like a home and promote independence.

Such models of residential aged care generally have:

  • flexibility in daily routines – for example, the time people get dressed and eat
  • opportunity for residents to participate in domestic activities such as meal preparation
  • access to outdoor spaces
  • clusters of smaller living units (up to, say, 15 residents in each)
  • care staff assigned to living units for continuity of care and development of relationships between staff and residents.

What we found

Our study was specifically designed to include people with dementia and their family members. People with dementia are not often included in research studies.

It included 541 participants from 17 not-for-profit residential aged-care facilities in four different states in Australia. They had been residents for a year or longer.

These facilities were all considered high quality. This means they had lower hospitalisation rates for potentially avoidable conditions than the national performance target. And more than 80% of residents in the standard care facilities indicated they felt as safe as they wanted and that their environment was as clean and comfortable as they wanted.

Around one-quarter of people in the study lived in a facility with a home-like model of care. All of them were living with dementia.

The study found residents in home-like models of care had a better quality of life, as rated by the residents themselves or their family members. They also had a 68% lower rate of being admitted to hospital and 73% lower rate of having an emergency department presentation.

We have previously shown residents who lived in a home-like model were 52% less likely to be exposed to potentially inappropriate medications. These are medications where the potential harms may outweigh the benefit, such as antipsychotics or relaxants, but are still often prescribed to older people in residential care.

The benefits for residents were provided with similar running costs for the home-like and the standard models of care. However, the costs excluded differences in the build of the facilities. Initial establishment costs are likely to be higher, due to the requirement for more space per resident.

Rethinking models of care

Funding arrangements don’t incentivise Australian aged-care providers to offer variety in terms of models of care. Government funding is provided based on the assessed care needs of the residents, rather than the preferred model of care or resident outcomes.

Funding supplements are available to care providers for reasons such as residents’ financial hardship or risk of homelessness and to small, rural aged-care service providers, but none are available for offering an alternative model of care.

The ConversationThe Australian government plans to improve the aged-care system to offer “choice and flexibility”. This is crucial, but we also need to improve choice and variety in residential aged-care models.

Circadian circuit may affect “Sundowning”

News Release
April 9, 2018 | Boston – Beth Israel Deaconess Medical Center

New Discovery May Calm ‘Sundowning’

sunset-1661088_960_720.jpg

BOSTON – Patients with Alzheimer’s disease and other forms of dementia commonly experience the sundown syndrome – a sudden worsening of confusion, agitation and aggression at the end of the day. Its daily pattern suggested that “sundowning,” as the phenomenon is also known, may be governed by the body’s internal biological clock. Synchronized by light and darkness, the circadian clock exerts control over wake/sleep cycles, body temperature, digestion, hormonal cycles and other physiological and behavior patterns. But whether the circadian clock regulated aggressive behavior was unknown.

Now, for the first time, a team of neuroscientists at Beth Israel Deaconess Medical Center (BIDMC) has demonstrated circadian control of aggression in male mice and identified the specific neurons and circuitry regulating the daily pattern. The insight opens the door to potential opportunities for managing the evening-time agitation common in patients with degenerative neurological disorders. The study was published today in Nature Neuroscience.

“Sundowning is often the reason that patients have to be institutionalized, and if clinicians can control this circuit to minimize aggressiveness at the end of the day, patients may be able to live at home longer,” said senior author Clifford B. Saper, MD, Chair of the Department of Neurology at BIDMC. “We examined the biological clock’s brain circuitry and found a connection to a population of neurons known to cause violent attacks when stimulated in male mice. We wanted to know if this represented a propensity for violence at certain times of day.”

Saper and colleagues observed aggressive interactions between male mice – resident mice defending territory against intruders introduced to residents’ cages at different times throughout the day. Counting the intensity and frequency of residents’ attacks on intruders revealed for the first time that aggression in male mice exhibits a daily rhythm.

“The mice were more likely to be aggressive in the early evening around lights out, and least aggressive in the early morning, around lights on,” Saper said. “It looks like aggressiveness builds up in mice during the lights on period, and reaches a peak around the end of the light period.”

Next, the scientists used genetics-based tools to manipulate neurons known to regulate the central circadian clock. When Saper and colleagues inhibited these neurons by disabling their ability to produce a specific neurotransmitter, the mice lost the daily waxing and waning of their aggressive tendencies. These genetically manipulated mice were more aggressive overall, demonstrating a significant increase in total time attacking intruders.

Using optogenetics – a technique that uses light to activate or deactivate targeted brain cells – to map brain circuitry revealed two parallel pathways between the biological clock and a population of neurons in a sub-region of the hypothalamus (called the VMHvl) known to cause violent attacks when stimulated in male mice.

Taken together, the experiments showed that this circadian circuit kept aggressiveness in check in the early morning; stimulating it prevented attack, while inhibiting it promoted attack. Because stimulating the neurons in question cools off aggression, Saper suggests that controlling this circuit could potentially make animals – and perhaps people – less aggressive.

“Our results in mice mimic the patterns of increased aggression seen in patients during sundowning,” Saper said. “This new research suggests this pathway may be compromised in neurodegenerative diseases. Examining changes to this pathway in patients could provide insight into future interventions that could greatly improve the quality of life for patients and caregivers alike.”

In addition to Saper, investigators included co-first authors William D. Todd and Henning Fenselau, Joshua L. Wang, Natalia L. Machado, Anne Venner, Rebecca Broadhurst, Satvinder Kauer, Bradford B. Lowell, and Patrick M. Fuller, of BIDMC and Harvard Medical School; Rong Zhang, of Boston Children’s Hospital and Harvard Medical School; Timothy Lynagh of the University of Copenhagen; and David P. Olsen, of the University of Michigan, Ann Arbor.

Learning from zoos – how our environment can influence our health

We are told that we are a nation of couch potatoes, lacking the will and the strength to turn around the obesity tanker. We all need a little help in our quest for a healthier life and design can play a crucial part. If we designed our towns, cities, homes and workplaces more like animal experts design zoos, we could be one step nearer to reaching our fitness goals – as long as we can have some fun along the way.

It is reported that British people will be the fattest in Europe by 2025 and that if we want to reverse this we should have a healthier lifestyle by exercising more and eating less. But we are often made to feel guilty for not sticking to theses healthy lifestyle plans. I would suggest that before we start blaming people for adopting sedentary lifestyles, we should be taking a step back to look at the design of the environments, towns and cities in which we live.

The link between the design of the built and natural environment and its role in our health and well-being has been well explored. Now new research, led by Lancaster University, on “design for health” suggests that the environment, including buildings, cities, urban spaces and transport infrastructure, is closely linked to the lifestyles we adopt.

What is abundantly clear is that, as we shape our environment, it is also shaping us. Our psychological, physiological and physical status as well as our interactions with other people and with the natural environment are all affected. A key challenge that governments and policy makers worldwide are facing is how our built environment and infrastructure should be shaped to support healthier behaviours to prevent disease.

First, we should stop focusing on methods that tell people what to (or not to) do and which attempt to change their behaviour simply through media campaigns and punitive measures, such as tax schemes. While seeking to minimise the barriers that prevent healthy behaviours, we should make sure that the design of new environments is taken into account.

Looking to zoos

A good model would be to look at how zoos are designed. Before a zoo is built, it is common practice for zoologists, biologists, animal psychologists, nutritionists, architects, designers and landscape architects to work closely together to create an environment that optimises the living conditions for the animals.

Important environmental elements, such as vegetation, habitat, lighting, materials and each animal’s requirements are taken into account. The ultimate aim is to design an environment that fully supports the animals’ physical, psychological and social well-being. Ironically, we do not seem to make the same demands when a town, neighbourhood or workplace environment for humans is planned and designed.

Another opportunity that has recently emerged is the healthy new town NHS initiative. The aim is to radically rethink how we live and take an ambitious look at improving health through the built environment. Ten demonstrator towns will be built across England with community health and well-being as their main focus. Clinicians, designers and technology experts will reimagine how healthcare can be delivered in these places. Although this is a step in the right direction, what it is currently missing is the more holistic approach we have seen in the design of the zoos.

A crucial element in designing these towns so they are places that people would want to live in, is to include community members in their creation. This strategy would help design-in health-promoting behaviours, such as access to healthy food outlets or green spaces in which people can walk and exercise.

Embracing playfulness

Playful design – the mapping of playful experiences from games and toys to other non-game contexts – can play an important role here in inviting and encouraging people towards healthier alternatives. For example, the piano stairs project in Stockholm, which converts the metro stairs into a giant functioning piano keyboard – much like the piano made famous in the Tom Hanks movie Big (1988) – demonstrates great promise. It encourages commuters to opt for the intriguing new stairway instead of the escalators to enjoy making musical movements as they go up and down.

A project in The Netherlands, meanwhile, illustrates how everyday street furniture, such as lampposts, benches and bollards, can be inexpensively converted into impromptu exercise devices, inviting people to engage in casual activity and socialise with their neighbours. We could therefore envisage several other contexts were playfulness can transform mundane everyday activities into fun ones that encourage people into a more active and social lifestyle.

We could convert building walls into activity walls to encourage stretching of arms and legs through touch; redesign public squares and walkways into interactive dance floors that invite movement and guide you through a city; and transform workplace spaces and public places into “playgrounds” that boost movement and productivity and decrease lethargy.

The Conversation

So there you have it. If we want to be a nation of lean, mean and healthy citizens we need to learn from zoos and the animals that live in them. And we need to embrace playfulness and enjoy the place where we live. That way, we can tackle life with a hop, skip and a jump.

Building a better world: can architecture shape behaviour?

US architect Frank Lloyd Wright, who designed Fallingwater, believed that appropriate architecture would save the US from corruption.

In 1966, a British planner called Maurice Broady came up with a new term for the architectural lexicon: architectural determinism.

This was to describe the practice of groundlessly asserting that design solutions would change behaviour in a predictable and positive way.

It was a new phrase but the belief system behind it – that buildings shape behaviour – had allowed the heroes of architecture to make all kinds of outlandish claims.

A hopeful history

Leon Battista Alberti, an Italian Renaissance-era architect, claimed in the 1400s that balanced classical forms would compel aggressive invaders to put down their arms and become civilians.

Frank Lloyd Wright, the US architect who designed one of the most famous buildings in America, Fallingwater, similarly believed appropriate architecture would save the US from corruption and turn people back to wholesome endeavours.

British author and thinker Ebenezer Howard believed companies would be more efficient if their employees lived in village-like garden communities.

Swiss-born French architect Le Corbusier made claims about how his Villa Savoye building in France would heal the sick – and when it did just the opposite, he only avoided court because of the commencement of the second world war.

It took a long list of failures over the millennia before postmodern theorists took to critiquing architectural fantasy with malevolent vengeance. The high-point of this trend was the delight shared over the demolition of the famously dangerous and dysfunctional Pruitt-Igoe urban housing complex in St Louis in the US.

It was designed by architects George Hellmuth, Minoru Yamasaki and Joseph Leinweber to provide “community gathering spaces and safe, enclosed play yards.” By the 1960s, however, it was seen as a hotspot for crime and poverty and demolished in the 1970s.

The demolition of Pruitt-Igoe in 1972 fuelled resistance to deterministic thinking.

The loss of faith in architecture’s power has been regrettable. Architects’ well-meant fantasies once routinely provided clients with hope and sometimes even with results.

Without this promise, the profession was left inept before the better structural knowledge of engineers, the cumulative restrictions imposed by generations of planners, the calculations of project-managers and the expediency of a draughtsman’s CAD (computer-aided design) skills in turning a client’s every whim into reality.

Without fiction, architecture has become a soulless thing. But was determinism dismissed too soon? Is there a role for imagined futures without rationalist restrictions?

Restoring the faith

Just think of some of the ways architecture can manipulate your own experience. In his book, Happy City: Transforming Our Lives Through Urban Design, US author Charles Montgomery points out that some environments predictably affect our moods.

The fact is that environments do affect us, regardless of whether by design or by accident. In 2008, researchers in the UK found that a ten-minute walk down a South London main street increased psychotic symptoms significantly.

In my own research, I find that the healthier a person is, the more a good environment will affect them positively and the less a bad one will affect them negatively. Mentally ill patients show about 65 times more negative reactivity to bad environments than controls and all these reactions translate directly into symptoms.

The same patients have about half the positive responsiveness. That’s fewer smiles, less laughter and a reported drop in feeling the “fun of life”.

But that’s not all. The potential for architecture is richer still. The ease with which architecture can embrace sublime aesthetics makes it great for generating awe.

Psychiatrists have found that awe reduces the prevalence and severity of mood disorders. Could sublime architecture even potentially save lives?

The psychological effects of architecture are difficult to prove, but difficulty doesn’t dilute the value of a building that hits the right notes and creates a sense of awe. Each building type has different functions, and for each there’s an imperative to use the building to help create an optimal mood, desire or sense of coherence, security or meaning.

Fortunately, there’s a resurgence of belief that buildings can change behaviour, led by a few architectural journals: World Health Design, Environment Behavior and HERD.

Most of these focus on health care design, because that’s where behavioural changes have life and death consequences.

But nobody dares make any promises. As such, research rarely opens the black box of environmental psychology, leaving findings unexplained and prone to failure.

To give architecture back its mojo, a new interest in how architecture changes us must be fostered. Clients have to learn to trust architects again and research funding bodies have to re-gear to encourage research into how buildings affect our mood, health and behaviours.

Finally, architecture schools have to teach students how they might predict psychological, emotional, healing and functional effects.
