All rapid responses
We read with interest the findings of Fairhead and Rothwells
study.[1] We discovered that amongst patients admitted with acute stroke,
brain imaging was performed only in a small proportion of older adults.
The most common misconceptions were that imaging older adults after an
acute stroke would not change management and therefore it would be a waste
of resources. After the appointment of a clinical lead in stroke, there
has been a sustained effort at changing this practice by a continuing
audit cycle, development of local acute stroke guidelines, regular
teaching sessions regarding the importance of appropriate prescribing of
anti-platelet agents, risk of haemorrhage with indiscriminate use of anti-
platelet agents, consequences of recurrent stroke and importance of its
prevention especially in the older adult. We are glad that this effort has
improved brain imaging in older adults in our hospital.

I have misgivings about this paper and about the suggestions of ageism in the accompanying editorial. In the introduction, we learn that lower rates of treatment in older people “might legitimately reflect … patients’ choice”. However, the conclusions of the abstract assert “a willingness to have surgery” on the part of elderly patients and in the discussion section of the main paper we are told that the low rate of endarterectomy in patients of 80 and above is ”unlikely to have been due … to patient choice”. Neither of these statements is supported by a reference. In the methods section, we are told that “all patients were interviewed and examined so that the potential appropriateness of carotid surgery could be determined”. However, we are not told how appropriateness was determined and from whose perspective.
When research findings contradict clinical experience, they demand careful scrutiny. My experience of talking to older people over many years is that many, although certainly not all, begin to lose their enthusiasm for hospital treatment of any sort after the age of 80, let alone for invasive surgery with a significant, albeit small, risk of harm. I note that in this study the gold standard was a decision made by the patient after discussions with surgeons who were not involved in the study. Ageism is undoubtedly operating in the distribution of healthcare resources in the UK but we should not forget that it can also occur when patients are persuaded to accept treatments that do not accord with their own values and aspirations. There is a real danger that locating ageism within rates of prophylactic surgery will distract attention from the much more pervasive expressions of ageism which are to be found in the lack of funding for the care of frail older people in England and particularly those suffering from dementia.

Dear Editor,
My deepest respect to Fairfield and Rothwell for doing this study and
to BMJ for publishing it.[1] Their findings echo those found in a past
BMJ paper that reported many ICUs in UK had age-based admission
criteria.[2] Both papers highlight an important social issue that affects
healthcare systems: ageism.
Ageism has been defined by sociologists as discrimination on the
basis of age and the mistaken belief that older persons benefit less from
medical interventions.[3,4] Why do physicians and healthcare systems
discount the demonstrated ability of older patients to benefit from
interventions and continue to deprive them of beneficial treatment? Is it
because of an underlying attitude that the elderly are a financial burden
to society or simple ignorance?
Ageism is a pervasive problem in society with its roots deeply
entrenched in stereotypical attitudes towards older persons that are
taught to us through society, media, and even the negative attitudes that
some older persons may hold of themselves. For anti-ageist practice to
become firmly established as a central part of good medical practice,
careful but concrete steps must be taken. We must have a deeper
appreciation of the ageist attitudes of society that run much deeper than
the level of personal values and individual concerns. It must take into
account the wider issues of culture, gender, race, and society’s
structural issues.[5] As healthcare providers, we must continue to keep
vigilant against ageist attitudes and policies that may creep into our
daily practice.

Geriatricians and stroke
The paper and editorial on investigation into stroke and ageism are
important
additions to the literature on ageism as a source of inequity in access to
healthcare (1, 2). One of the missing pieces of information is the
specialty or
sub-specialty of the physicians providing secondary care in the Oxford
study.
Allowing for selection bias in admissions, there is evidence that care
under a
neurologist or geriatrician can be associated with a higher levels of
investigation in stroke, or avoidance of harmful therapy (3). Nursing
styles
and team work in stroke care in geriatric medicine wards has been
demonstrated to be more appropriate than in general medicine and stroke
unit care (4), and the use of Acute Care of the Elderly principles has
been
shown to be an effective basis for the development of stroke unit care
(5).
It is notable that the UK and the Ireland have evolved models of
stroke unit
care with clinical leadership from both geriatricians and neurologists, in
conjunction with rehabilitationists. This unique combination allows for
the
introduction of gerontological principles and models of care that
facilitate
care for an age-related disease, as well as balancing advocacy against
ageism
with a biopsychosocial approach. The effectiveness of the gerontological
approach to medical care has been demonstrated for acute general medical
admissions (6): it is vital that the advantages of this dual approach are
developed and expanded in stroke care.
