(1) STUDY REVEALS ETHNIC DIFFERENCES IN
TREATMENT FOR HEART DISEASE

(Ethnic differences in invasive management of
coronary disease: prospective cohort study of
patients undergoing angiography)
http://bmj.com/cgi/content/full/324/7336/511

South Asian patients are less likely to receive
treatment for coronary artery disease than white
patients, finds a study in this week's BMJ.

Researchers in London compared rates of coronary
revascularisation (a procedure to restore adequate
blood supply to the heart) in 502 south Asian and
2,974 white patients with heart disease.

Although the same proportion of south Asian and
white patients were deemed appropriate to undergo
revascularisation, south Asian patients were less
likely to receive it than white patients. This difference
cannot be explained by physician bias or
socioeconomic status of patients, say the authors,
but they suggest that south Asian and white patients
may differ in their understanding of the risks and
benefits of the procedure.

These findings provide the strongest evidence to date
that coronary revascularisation among comparable
patients with heart disease is less likely to be carried
out in south Asian patients than in white patients in
the United Kingdom, say the authors.

The national service framework for coronary heart
disease in England and Wales explicitly requires the
equitable provision of revascularisation between
ethnic groups; this may not be happening, they
conclude.

(2) ARE ONE STOP BREAST CLINICS
JUSTIFIED?

(Costs and benefits of a one stop clinic compared
with a dedicated breast clinic: randomised controlled
trial)
http://bmj.com/cgi/content/full/324/7336/507

One stop clinics for assessing women with suspected
breast cancer may not be as cost effective as
previously thought, according to a study in this
week's BMJ.

Women aged 35 or over who were referred to
hospital with a breast lump were randomly allocated
to attend either a dedicated breast clinic or a one
stop clinic. The costs and benefits of each clinic were
measured and compared.

Compared to women attending the dedicated clinic,
those attending the one stop clinic were less anxious
24 hours after their visit but not at 3 weeks or 3
months after diagnosis. A one stop policy cost £32
more per patient. The costs saved by reducing the
number of visits are more than offset by the staff
costs of same day reporting of diagnostic tests, say
the authors.

Benefits of one stop clinics are, in the main, short
term, and may not justify the added costs, they
conclude.

Before the one stop breast clinics that already exist
are dismantled on the basis of these results, several
issues need to be considered, writes Michael Dixon
in an accompanying commentary. They should not
yet be abandoned, but their supporters do need to
show that if they see more patients per clinic and use
a more selective testing policy than in this study, the
benefits are not outweighed by the costs, he
concludes.

(3) HOMOEOPATHY IS NOT AN EFFECTIVE
TREATMENT FOR ASTHMA

(Use of ultramolecular potencies of allergen to treat
asthmatic people allergic to house dust mite: double
blind randomised controlled clinical trial)
http://bmj.com/cgi/content/full/324/7336/520

(Editorial: Randomised controlled trials for
homoeopathy)
http://bmj.com/cgi/content/full/324/7336/498

Homoeopathic remedies are no better than placebo
for the treatment of asthmatic patients who are
allergic to house dust mite, but there is a difference in
response between homoeopathy and placebo,
concludes a study in this week's BMJ.

The research team identified 242 asthmatic people
allergic to house dust mite. Participants received
either homoeopathic therapy or placebo and were
assessed over 16 weeks.

They found no improvement in lung function or
quality of life between those treated with placebo
and those who received homoeopathic therapy.
They conclude that a homoeopathic dose of house
dust mite therapy is no better than placebo for the
treatment of people with asthma who are house dust
mite allergic.

Previous studies have suggested that this type of
homoeopathy is effective in the treatment of hay
fever and possibly asthma. However, this study was
substantially larger than any of the earlier studies and
included a wider range of outcome measures, say the
authors.
