Conference Report: The Society for Acute Medicine Spring Meeting – April 22nd to 23rd 2004

For this year’s spring meeting, the Society for Acute Medicine took us to Bournemouth on the sunny south coast of England. The Marsham Court Hotel served as an excellent venue for this, the ninth meeting of the society, which ran for two days over the 22nd and 23rd of April. Sunshine, the grand Pier and long stretches of raked beach augmented a relaxed and friendly atmosphere and provided a spectacular backdrop for coffee breaks between sessions.

Benefits of an Emergency Assessment Area Medical Review Clinic: prospective evaluation

Summary

Following the establishment of a medical review clinic in an Emergency Assessment Area (EAA) the reasons for and the appropriateness of referral of patients after initial visit were prospectively analysed in 167 patients. An attempt was also made to establish the number of patients who would have been admitted if the clinic were not in place and thus the potential saving of bed-days from this new initiative. Three main reasons for referral were the uncertainty about diagnosis, uncertainty about management and the review of outstanding investigations. Fifteen per cent of patients were judged to have been inappropriately referred. In 22% of patients the presence of the clinic prevented hospital admission and it was also felt that in a further group of patients the clinic provided a useful role in reassuring the patient, reinforcing and reviewing management plans. The clinic also acted as an educational tool for junior doctors. Thus the development of an early review clinic in an Acute Medical Unit / EAA setting is a useful adjunct to the delivery of high quality ambulatory patient care.

Controversies in acute medicine: Oxygen therapy for exacerbations of chronic obstructive pulmonary disease (COPD)

Abstract

Some patients with COPD ‘retain CO2’ when given high concentration or uncontrolled oxygen therapy. The mechanism for this, and why it occurs in only some patients, is unclear. The pathogenesis of chronic hypercapnia in COPD involves multiple, poorly understood mechanisms. During acute exacerbations ‘CO2 retention’ is thought to occur due to redistribution in ventilation-perfusion with oxygen therapy, although some studies suggest reduced ventilation also contributes. Problems arise when inexperienced staff extrapolate this teaching to include all patients with hypercapnia. The most common cause of hypercapnia is ventilatory failure. Teachers need to emphasise how to recognise ventilatory failure and the dangers of hypoxaemia in critically ill patients.

Medical Emergencies in Human Immunodeficiency Virus (HIV) Infection

Abstract

With increasing awareness, earlier diagnosis, and aggressive use of anti-retroviral therapy, more people with HIV are living longer so that the average survival time from diagnosis is now significantly better than what it was 10 years ago. As a consequence of this, more patients with HIV are now presenting to hospitals and emergency departments as acute medical emergencies either directly related to their HIV infection, or their treatment.1 An awareness of the potential problems with which these patients can present to hospital, plus guidance on their management is essential to all acute care physicians. In this article we outline the general management of patients with HIV presenting as emergencies to hospital, and then systematically focus on some of the more common clinical problems which may arise.

Management of Tuberculosis for the Acute Physician

Abstract

Tuberculosis is increasing world-wide and also in England and Wales, where there are marked geographical and ethnic variations. Acute physicians should be aware of this, and also of the variable manifestations of this multisystem disease, as well as current epidemiology which informs clinical risk stratification. Treatment is highly evidence based, and bacteriological confirmation should be sought whenever possible, partly because of the current level of drug resistance.

The Emergency Management of Adult Bacterial Meningitis

Abstract

Over the last decade, new protein-conjugate vaccines against Haemophilus influenzae type b (Hib) and Neisseria meningitidis serogroup C (MenC) have had a dramatic effect on the epidemiology of childhood meningitis in the United Kingdom. Amongst adults, bacterial meningitis remains an important cause of preventable morbidity and mortality. Clinicians need to remain vigilant for the possibility of this infection. The identification of the one patient with meningitis out of many with trivial viral infections remains a difficult task. Even once the diagnosis is made clinically, the subsequent investigation and management of the patient remains controversial, with strong opinions often influenced by one or two adverse experiences. Potential improvements in the way we identify and manage meningitis patients have been identified in recent years. This review will focus on those areas relevant to the emergency care specialist. Meningitis in the immunocompromised patient often has a different clinical and epidemiological pattern and is beyond the scope of this review.

Acute Hypoglycaemia: Diagnostic criteria, Investigation and Management for the Emergency Physician

Abstract

Hypoglycaemia is a common condition, which may easily be missed due to the variation in clinical presentation in patients with or without diabetes. The most common cause is related to the treatment of diabetes. Non-diabetes related hypoglycaemia is rare. Nonetheless, the need for careful evaluation of the underlying cause is important as well as relieving symptoms.

The diagnosis and investigations involved in management of hypoglycaemia are discussed with a direct relevance to the acute general physician.

Editorial

Over the past three years it has become apparent to me that referring to ‘current affairs’ in these columns can be a mistake, serving only to highlight inevitable printing delays. By the time this edition arrives on your doormat Euro 2004, ‘Big Brother’ and the early summer heat wave will be nothing but a distant memory. However the ‘recent’ publication of the Royal College of Physicians document ‘Acute Medicine – making it work for patients’ cannot be allowed to pass without a mention. This report represents a significant shift in the position of the College in relation to Acute Medicine since the previous working party reported its findings in 2000. The value of consultants specialising in Acute Medicine is now clearly recognised and supported – every trust should now have one, with the minimum figure of three per hospital being proposed by 2008. Whether this is achievable will depend on the rapid development of training schemes across the UK, as well as the generation of enthusiasm for the specialty amongst junior staff. The number of applicants for our Wessex programme indicates no shortage of the latter. Although developing a training scheme takes a lot of hard work, it is vital that those already working in the specialty make this a high priority. We have already seen benefits from the appointment of high quality middle grade staff and are looking forward to a ‘flood’ of future applicants for local consultant posts, 4 years from now.

This edition comprises four more important review papers on aspects of acute medicine, along with the first in our ‘Controversies in acute medicine’ series. The latter was designed to try to stir up some correspondence, for future publication. The confusion over oxygen delivery in the acute setting seems to reign fairly widely amongst junior, and indeed some more senior medical staff. Hopefully Dr Cooper’s well-written paper will serve to dismiss some of the misconceptions in this area. Our reviews cover relatively uncommon, but nonetheless important aspects of acute medicine. Tuberculosis and HIV are both on the increase in the UK. The success of anti-retroviral therapy will undoubtedly lead HIVrelated illness to be a significant part of our practice over the next decade. An understanding of the range of conditions specific to this group of immunocompromised patients is therefore crucial for physicians involved in the acute take. Hypoglycaemia and suspected bacterial meningitis are both conditions which require immediate action by medical staff. Both of these reviews comprehensively cover their respective topics with a combination of well written text, illustrations tables and algorithms. Dr Hartman highlights recent evidence supporting the use of dexamethosone in bacterial meningitis and re-iterates some of the points made in an earlier edition regarding the use (and abuse) of CT scanning prior to lumbar puncture.

For a change we have no case reports this time, although Dr Macdonald’s audit of the innovative review clinic in the Emergency Assessment Area of Heartlands hospital provides a worthy substitute. Submission of similar articles in future would be most welcome.

Once again, a reminder that multiple choice questions are for self assessment and ‘personal’ CPD only; I hope you will find this edition helpful in your clinical practice.
