discuss alternative sites for vaccination if there is any tendency for keloid or hypertrophic scar formation in the individual. We believe that it is for the profession to impress on the public that every attempt is made to control the disease and that an "unavoidable" scar is a small price to pay for this.

BCG vaccination scars SIR,-Mr Roy Sanders and Mr M G Dickson (11 December, p 1679) have clearly described the management of the BCG scar and have suggested an alternative site as a solution to the problem. They have not, however, described the need for some uniformity in the policy and the management of medicolegal implications. We wish to describe our experiences and thus convey the occupational health problems associated with the BCG scar. Hospital employees are at a higher risk of contracting tuberculosis and are screened for evidence of tuberculosis or vaccination in the past before their employment. It is easy to rescreen the population seeking employment for evidence of previous BCG vaccination when a conventional site is used. There is no better evidence of BCG vaccination than the presence of a scar. We tried ascertaining the vaccination state by retrieving this information from general practice records. Only 220' of these records contained the information. In view of this observation we screened all prospective employees and found that 23 0 had escaped BCG vaccination in school. Vaccination can be given in any of the alternative sites mentioned in the leading article provided the request is made at the time of vaccination. Unfortunately, dissatisfaction is usually expressed long after the event. Between 1975 and 1981 we administered 500 BCG vaccinations. Only two claims for compensation were made-two and three years after the vaccination. Both complainants (female) stressed their dissatisfaction with the site rather than the nature of the scar; the scars were conventional in both women. The inability to wear garments that do not cover the scar was the reason given for their dissatisfaction. BCG is usually given by the school health service in this country before the age of 13. Fashion changes with time and imposes on the profession the need to modify periodically the site of vaccination to prevent

in appropriate cases in order to identify the occasional case where there is a need for subsequent follow up or even biopsy. We must remember that cervical cancer can rarely present in pregnancy. Patients having shared care should return to the specialist antenatal clinic around 32 weeks' gestation, mainly so that the specialist can check the presentation and measure blood pressure, fetal growth, etc. Around 36 weeks she should again attend the specialist clinic mainly so that he can make an assessment of pelvic adequacy and consider the prospects for labour in addition to the other customary observations. When maturity is reached patients should attend the specialist clinic weekly to ensure that postmaturity will not endanger the fetus. The sentiments expressed by Dr Bull regarding good communications should be applauded. The national cooperation card should enable most useful information to be exchanged. Otherwise, what is needed is a feeling of teamwork, with professional groups cooperating and complementing each other. Each should to some extent cross check the observations made on the patient and be prepared to alert the team if the case is deviating from normal. I have no doubt that good cooperation of this type is in the best interests of patient care. R M BURTON

SIR,-Dr W A M Cutting replied to your leading article (11 December, p 1679) that a small pitted scar over the deltoid was not sufficient for a BCG immunisation programme to consider changing its site of innoculation or discontinuing vaccination (8 January, p 148). Dr Cutting seems to have completely misunderstood the argument. No one is bothered about a small pitted scar. The deltoid area, however, happens to be, after the presternal area, the area of the body most susceptible to keltoid scarring. This is a disabling condition for which there is no satisfactory treatment. Movement of the site of inocculation by only a few centimetres would make BCG innoculation scarring a rarity. Far from jeopardising the inoculation programme its acceptibility could only be increased. BRYAN J MAYOU Perivale Maternity Hospital, St Thomas's Hospital, London SE1 7EH

***This correspondence is now closed.-ED, BM7. The GP and the specialist: obstetrics

SIR,-Over many years I have become convinced that shared care in obstetrics, discussed by Dr M J V Bull (8 January, p 141), is in the best interests of patients, even for those who may be considered normal. Clinical assessment should have a somewhat critical approach, resisting the assumption that a case is necessarily normal and will remain normal in every particular. For shared care to function satisfactorily both the general practitioner obstetrician and the specialist must be able to carry out their proper functions. Patients should certainly be referred early for specialist assessment. By early I mean about 10 weeks' gestation and I hope not as late as 16 weeks. The dating of a pregnancy is often called into question, in many cases at an advanced stage of gestation. In this event most reliance should be placed on a careful bimanual examination by a specialist obstetrician of some experience carried out at this early stage. The specialist should assess the size of the uterus relative to the dates, exclude any abnormality of the genital tract, and in most cases make an assessment of the mechanical adequacy of the pelvis. Most patients appreciate the need for such examination, and the minority who over-react can be counselled and encouraged to attend for future litigation. Fortunately, most recipients parentcraft lessons to gain confidence and of the vaccination are grateful for the service understanding. Rhesus grouping and rubella immunity and accept the scar. It is for a small minority that we have to offer an alternative site to avoid state should certainly be checked as soon as legal complications.

Intensive attention improves glycaemic control in insulin dependent diabetes

SIR,-We were interested to read the results reported in the letter from Dr R H Harrad and others (1 January, p 59). The problem of motivation (of both patient and doctor) is fundamental to achieving improved control of blood glucose concentrations with present methods. The excellent control that can be achieved in nearly all cases of diabetic pregnancy is a good example of the strong motivation that patients can have, which often wanes following delivery. It is much more difficult in our experience to generate and maintain the necessary enthusiasm in diabetics who are otherwise perfectly well and free of complications, We infer from their letter that Dr Harrad and others selected their patients on the basis of their retinopathy. We wonder, if this is true, whether the patients were told that they had retinopathy since this could provide a very powerful incentive to the patient to intensify efforts to improve control. Any improvement in control as a result of home blood glucose monitoring alone does seem to depend on the procedure being performed several times daily on a regular basis. As we indicated in our original paper, we were not able to maintain this intensity in our group of uncomplicated diabetics. The problem of motivation seems to remain, therefore, the major difficulty. Whatever the reason, however, the sustained improvement in control obtained in the patients at St Thomas's Hospital is encouraging. We would agree that a specialist diabetic nursing sister may well be thought by a diabetic to be more approachable than a doctor, hence prompting more frequent contact between patient and counsellor.

Hours of work of junior hospital doctors SIR,-While supporting the efforts of the Hospital Junior Staff Committee to reduce the unacceptable burden of work represented by a one in two rota for resident house staff we do not accept that similar changes in the on call rotas for registrars and senior registrars are desirable or feasible if standards of patient care and surgical training are to be maintained. Such a reduction in on call rotas would be possible only with a system of cross cover, whereby patients would be cared for by doctors unacquainted with their cases; we do not consider this acceptable in surgery. As surgeons in training we have a responsibility to all our patients and particularly those on whom we have operated, and we would expect to be called should postoperative problems occur. Thus our out of hours work pattern is dictated by the vicissitudes of surgery, and a reduction in rotas to one in three would not change our commitments but merely provide an excuse for regional health authorities to cut units of medical time against the wishes of both consultants and senior registrars on the grounds that the BMA recommends the move. We urge all surgical staff (and those of other acute specialties) seriously to consider the effects of the current BMA recommendation on patient care and registrar training. We suggest that a one in three rota is against the interests of most, if not all, senior surgical registrars and that current practice at regional level and above should not be changed without the agreement of all the individuals concerned; we also suggest that the BMA's recommendations should be restricted to resident hospital doctors.

Budgeting for pharmaceuticals SIR,-Mr Mahesh Patel (15 January, p 241) claims that drugs account for over 15%, of total health expenditure and that drug sales are rising at about 15%/ annually. It may help to clarify this point if it is noted that, in manufacturers' price terms, total sales to the NHS (family practitioner services and hospital sector combined) actually accounted for about 9-2% of total UK health service spending in 1981. Non-economists might also note that Mr Patel was not adjusting for inflation when he claimed that expenditure on medicines is climbing at 15% a year. Another way of presenting the available data is to say that, although there were some fluctuations, NHS pharmaceutical spending (again in manufacturers' prices) rose only slightly as a percentage of total NHS outlays throughout the 1970s. In 1970 it approximated to 8 4% of all NHS expenditure. D G TAYLOR Deputy Director Office of Health Economics, London SWIA 2DY
