Canadians over 65 years old use over 40 per cent of hospital services, a demand that continues to rise. As they age, Canadians hope to stay at home as long as possible. If hospitalization is required, they should expect to go home quickly and safely afterwards. Yet many spend weeks to months in a hospital bed, acquiring new health problems and disabilities, only to find themselves as one of over 300,000 Canadians living in a nursing home.
If hospitals are meant for getting well, why does this happen?
Our healthcare system was designed in the 1950s. Back then, it was about unexpected emergencies, like pneumonia or injuries. Conditions like heart attacks had few beneficial treatments so most patients did not survive very long.
Today, advances in medical science and public health mean that more people survive with conditions that would have killed their grandparents. Conditions that can be treated but not cured are called “chronic diseases.” The biggest risk factor for chronic diseases is aging. As Canadians get older, they usually acquire not one, but many chronic diseases.
Many older Canadians also develop other age-related problems such as dementia, making simple everyday tasks more difficult. Many lose muscle strength, becoming less active and more disabled.
Over time, the burden of these problems grows, and affected persons become increasingly vulnerable. Simple health challenges like influenza, nothing more than a nuisance to young people, will incapacitate or kill a vulnerable older person. This vulnerability is called frailty.
The problem is that hospitals remain better suited to care for healthy surgical patients and acute illnesses like pneumonia. Most are not geared to help frail seniors cope with acute illnesses or flare-ups of chronic conditions. Frailty is why so many do poorly in senior-unfriendly hospital environments, often becoming more confused and disabled, often irreversibly.
So what can be done?
First, hospitals need to identify vulnerable patients with complex needs to quickly address and minimize complications. Detection requires that the right information be collected efficiently and reliably at the right time.
Ideally, information about complex needs and frailty should be identified early, in all healthcare settings, using a common approach. Doing so means that important information can be gathered and acted upon even before a hospitalization.
Most of the pieces for this are in place in Canada, but not in hospitals. Existing hospital documentation systems are bloated and inefficient, collecting some information repetitively but missing other important data.
Yet knowing who’s at risk ensures that patients with mobility issues do not stay bedridden a minute longer than needed. It means that patients with dementia are regularly oriented to place and time and maintained on a stable daily routine. It means aggressive de-prescribing programs to get rid of harmful or useless medications.
It also means a more efficient health system.
An international not-for-profit group of researchers has carefully designed and studied instruments for just this purpose. interRAI assessment tools are already used in home care, nursing home and mental health settings across Canada. Unfortunately, they are not used yet in primary care and hospitals where measuring frailty is typically an afterthought, if done at all.
Along with our colleagues, we recently studied the interRAI Hospital Suite in 10 Canadian hospitals on over 5000 older adults, supported by the Canadian Frailty Network. The instruments were easy to use and were able to reliably predict, within 24 hours of hospitalization, which older patients would develop complications in hospital, which ones were at risk of a long hospital stay, and which ones were at risk of ending up in a nursing home.
Efforts are already underway to make our hospitals senior friendly, but the lack of systematic assessment in the system overall leaves us all vulnerable as we age. By the time frail patients need hospital care, it is often too late to addressing their complex needs.
Reliable information is a fundamental requirement to make our health care system and especially our hospitals senior friendly, allowing better targeting of programs to respond to needs along the entire trajectory of life.
