(1) EATING FISH CUTS RISK OF DEMENTIA

(Fish, meat, and risk of dementia: cohort study)
http://bmj.com/cgi/content/full/325/7370/932

Elderly people who eat fish or seafood at least once a
week are at lower risk of developing dementia, including
Alzheimer's disease, finds a study in this week's BMJ.

Using data from a large ageing study, a team of French
researchers set out to test whether there was a relation
between consumption of fish (rich in polyunsaturated fatty
acids) or meat (rich in saturated fatty acids) and risk of
dementia.

The study involved 1,674 people aged 68 and over
without dementia and living at home in southwestern
France. Their frequency of consumption of meat and fish
or seafood was recorded as daily, at least once a week
(but not every day), from time to time (but not every
week), or never. Participants were followed up two, five,
and seven years afterwards.

Participants who ate fish or seafood at least once a week
had a significantly lower risk of being diagnosed as having
dementia in the seven subsequent years. When education
was taken into account, the strength of the association was
slightly reduced, suggesting that this "protective" effect was
partly explained by higher education of regular consumers,
say the authors. They found no significant association
between meat consumption and risk of dementia.

As well as providing vascular protection, the fatty acids
contained in fish oils could reduce inflammation in the brain
and may have a specific role in brain development and
regeneration of nerve cells, suggest the authors.

Healthy dietary habits acquired in infancy could be
associated with achievement of higher education. Highly
educated people might also adhere more closely to dietary
recommendations on fish consumption, they conclude.

(2) NEEDS OF PEOPLE DYING OF HEART FAILURE
NOT BEING MET

(Dying of lung cancer or cardiac failure: prospective
qualitative interview study of patients and their carers in the
community)
http://bmj.com/cgi/content/full/325/7370/929

(Editorial: Palliative care for heart failure)
http://bmj.com/cgi/content/full/325/7370/915

The needs of people dying of heart failure are not being
met, finds a study in this week's BMJ.

Researchers at the University of Edinburgh compared the
experiences of 20 people with lung cancer with those of
20 people with advanced heart failure, using interviews
every three months for up to one year with patients, their
carers, and key professional carers.

They found that patients with lung cancer had access to
good quality written information and most understood their
illness and its causes. In contrast, patients with heart failure
rarely recalled being given any written information, had a
poor understanding of their condition, and had less
opportunity to address end of life issues.

More health and social services, including financial benefits
were available to those with lung cancer, although they
were not always used effectively. Cardiac patients
received less health, social, and palliative care, and care
was often poorly coordinated.

Many patients with end stage chronic illnesses do not
receive appropriate services because their
multi-dimensional needs are not understood, and their
prognosis is uncertain, say the authors. They argue that all
patients with advanced serious illness should be afforded
the same priority for palliative care as patients with cancer.
Care should be prioritised according to the degree of need
the patient has, not simply according to the diagnosis.

Care for patients with advanced heart failure should be
proactive and designed to meet their specific needs, they
conclude.

(3) PATIENTS WITH CHRONIC ILLNESS NOT
BENEFITING FROM ADVANCES IN CARE

(As good as it gets? Chronic care management in nine
leading US physician organisations)
http://bmj.com/cgi/content/full/325/7370/958

Many patients with chronic diseases are not benefiting
from advances in care because of a lack of financial and
staff resources, inadequate information systems, and
doctors' heavy workload, argue US researchers in this
week's BMJ.

They assessed the extent to which evidence-based chronic
care management processes and computer based clinical
information systems were used to care for patients with
asthma, congestive heart failure, depression, and diabetes
in nine leading physician practices in the United States.

The care management processes studied were the use of
practice guidelines, population disease management, case
management, and health promotion or disease prevention
activities.

Although they found several examples of high quality care,
some of the medical groups used few, if any, care
management processes. In some cases care management
processes were discontinued because of financial and
staffing problems.

Nearly all study groups used clinical practice guidelines for
all four chronic conditions. However, the use of other care
management processes varied greatly across conditions,
with fewer than half of the nine groups using all four
processes. The use of computer based information system
functions also varied greatly among the groups.

They identified several barriers to the use of care
management processes including lack of financial and staff
resources, inadequate clinical information systems,
doctors' heavy workload and doctors' resistance to
change. One medical director said, "We have a major
problem with overwork in primary care, and it's getting
worse. It is impossible to launch any programme that gives
physicians more work."

The future agenda for restructuring practices should
include addressing workload issues, promoting a culture
that supports quality improvement, expanding clinical
information systems, and financial incentives to reward
practices that improve the care and outcomes of patients
with chronic disease, they conclude.

(4) COMPUTERISED GUIDELINES ARE NO "MAGIC
BULLET"

(Effect of computerised evidence based guidelines on
management of asthma and angina in adults in primary
care: cluster randomised controlled trial)
http://bmj.com/cgi/content/full/325/7370/941

Computerised guidelines do not improve care for patients
with chronic diseases, and are unlikely ever to be the
"magic bullet" that answers all questions, finds a study in
this week's BMJ.

Martin Eccles and colleagues set out to evaluate the use of
a computerised decision support system delivering
evidence based guidelines for asthma and angina in 60
general practices in north east England.

The computerised guidelines had no significant effect on
consultation rates, any aspect of the process of care, or
prescription of any category of drugs in patients with
asthma or angina. This was probably due to low levels of
use of the software, despite the system being optimised as
far as was technically possible, say the authors.

Certainly in terms of implementing evidence based care,
computerisation seems unlikely to be the "magic bullet" that
answers all questions, and the current system could not be
recommended. Even if the technical problems of producing
a system that fully supports the management of chronic
disease were solved, there remains the challenge of
integrating the systems into primary care, where busy
practitioners manage patients with complex, multiple
conditions, they conclude.
