(1) POOR DIABETES CONTROL LINKED TO
PREGNANCY COMPLICATIONS

(Association between outcome of pregnancy and glycaemic
control in early pregnancy in type 1 diabetes: population based
study)
http://bmj.com/cgi/content/full/325/7375/1275

Women with poorly controlled diabetes during early
pregnancy run an increased risk of their baby being
malformed, finds a study in this week's BMJ.

Researchers in Norwich identified 158 first pregnancies in
women with type 1 diabetes. They defined adverse pregnancy
outcome as spontaneous abortion, major congenital
malformation (potentially life threatening or associated with
serious long term disability), stillbirth, or infant death.

The women were divided into two groups according to their
level of blood glucose control - a group with fair control and a
group with poor control.

Adverse outcome was over fourfold higher in the poor control
group than the fair control group. Compared with the fair
control group, the poor control group had a fourfold increase
in spontaneous abortion, and a ninefold increase in major
congenital malformation. Stillbirth or infant death was also
higher in the poor control group, but the difference was not
significant.

This study confirms earlier reports of increased risk of
spontaneous abortion and malformation with poor glycaemic
control in early pregnancy in women with type 1 diabetes, say
the authors.

"Our findings suggest that good glycaemic control around the
time of conception is necessary to optimise outcome of
pregnancy in diabetic women. Diabetic women and their
carers need to be advised of the risks and encouraged to
optimise glycaemic control before and during pregnancy," they
conclude.

(2) SURVIVAL AFTER MELANOMA NOT AFFECTED BY
SURGICAL BACKGROUND

(Observational study of type of surgical training and outcome
of definitive surgery for primary malignant melanoma)
http://bmj.com/cgi/content/full/325/7375/1276

Survival of melanoma patients does not depend on the surgical
background of the person removing the primary tumour,
concludes a study in this week's BMJ.

Such a specialist treatment effect has been observed for breast
cancers, with better outcomes for surgeons who carry out
breast cancer surgery regularly.

Researchers at the University of Glasgow identified 4,159
melanoma patients. All patients had had their primary
melanoma removed between 1979 and 1998. They divided
the surgeons performing the procedure into dermatological,
plastic surgery, or general surgery training.

They also looked at the effect within the three surgical groups
of treating up to six or more than six primary melanomas
annually.

They found no evidence that any type of surgeon performing
excisions of primary melanomas regularly had a better
outcome than those who carried out fewer excisions, possibly
because it is a relatively simple procedure.

The authors therefore recommend referral of suspected
primary melanomas to the dermatological, plastic surgery, or
general surgical service with the shortest surgical waiting time.

(3) LOWER RISK THRESHOLDS FOR HEART DISEASE
NEEDED

(Application of Framingham risk estimates to ethnic minorities
in United Kingdom and implications for primary prevention of
heart disease in general practice: cross sectional population
based study)
http://bmj.com/cgi/content/full/325/7375/1271

General practitioners should use lower risk thresholds for
heart disease when they are treating high blood pressure in
people from ethnic minorities, finds a study in this week's
BMJ.

The current recommended threshold predicts the risk of heart
disease with reasonable accuracy in white people, but
underestimates the risk in people of south Asian and African
origin.

Researchers identified 1,069 men and women from nine
general practices in south London. All participants were aged
40-59 years, 404 were white, 342 were south Asian, and 323
were of African origin.

They used a standard risk threshold of 15% to compare the
ten year risk of coronary heart disease (CHD), stroke, and
combined cardiovascular disease (CVD). This threshold
identifies 91% of white people, but only 81% of south Asians
and people of African origin for blood pressure treatment.

After adjusting for age and sex, the estimated 10 year risk of
CHD varied significantly by ethnic group. South Asians had
the greatest risk of CHD and combined CVD, whereas
people of African origin had the lowest. However, people of
African origin had the highest risk of stroke.

These results imply that we should be using lower thresholds
of CHD risk when treating raised blood pressure in people of
African or south Asian origin, say the authors. Using
thresholds of 12% in south Asians and 10% in people of
African origin would increase the probability of identifying
those at risk to 100% and 97% respectively. Risk of CVD
would be an even better measurement, they conclude.

(4) CONCERNS OVER PUBLIC REPORTING ON
QUALITY OF CARE IN THE NHS

(Attitudes to the public release of comparative information on
the quality of general practice care: qualitative study)
http://bmj.com/cgi/content/full/325/7375/1278

The public disclosure of information about quality of care is a
central component of UK government plans for the reform of
the NHS.

A study in this week's BMJ finds that the public and health
professionals support the principle of publishing information
about general practice performance, but are concerned about
the practical implications.

Researchers conducted 12 focus groups with 35 patients, 24
general practitioners, and 18 quality improvement clinical
managers in an urban area in north west England and a
semirural area in the south of England.

Patients regarded public disclosure as a political initiative and
were uneasy about practices being encouraged to compete
against each other. They were also more inclined to trust their
own experience or that of friends and family than to trust
comparative data. One person said: "If I saw my own doctor
being slagged off in the Good Doc Guide, I'd still go to him
because personally he suits me and I've got faith in him."

General practitioners focused on the unfairness of drawing
comparisons from current data and the risks of "gaming" the
results, while managers were concerned that public release of
the information would encourage a "name and shame" culture
in general practice, damaging their developmental approach to
improving quality. One commented: "We'll get cover-ups, we'll
get further entrenched in our blame culture."

These findings should not derail an initiative that has the
potential to improve accountability and stimulate
improvements in quality. However, the technical barriers, the
antipathy of the general public, the impact on professional
morale, and the opportunity costs of focusing on public
reporting at the expense of other health service reforms,
should not be discounted, say the authors.

A greater understanding of the practical implications of public
reporting is required before the potential benefits can be
realised, they conclude.
