A national audit of the secondary care of "acute" asthma in Wales--February 2006.

BACKGROUND: No national audit of acute asthma in secondary care has been undertaken since 1991 in spite of further revisions of national guidelines. There has been no audit of the patient course through the ambulance, accident and emergency units (A&E), medical admission units (MEAU) and in-patient care in an integrated manner. AIM: To audit the care of acute asthma in the various areas of secondary care in all hospitals in Wales in February 2006. METHODS: Standardised audit forms were produced to assess ambulance performance during transfer, A&E and MEAU care and in-patient care where admission occurred. The results were compared to national guidelines. RESULTS: Acute asthma in Wales is a common reason for hospital attendance, 30% of such patients appear to be mild but 19% are severe/acute severe. British Thoracic Society (BTS)/Sign assessment of severity is rarely performed and both monitoring of progress and the discharge process are disappointing. There are major incompatibilities between BTS/Sign guidelines and the current Welsh Ambulance Service protocol. A similar problem exists with the British Society of Accident and Emergency Medicine (BAEM) protocol for moderate asthma. CONCLUSIONS: This audit demonstrates disappointing adherence to BTS/Sign guidelines for the care of acute asthma. A new approach to acute asthma care in Wales is required.

Longitudinal study of sensitization to natural rubber latex among dental school students using powder-free gloves.

BACKGROUND: A high rate of sensitization and clinical allergy to latex proteins has been reported in health care personnel. This is thought to be due to increased occupational exposure especially to natural rubber latex (NRL) gloves with an estimated prevalence varying widely (2.8-18%). OBJECTIVE: This was a longitudinal study to monitor a cohort of first-year dental students throughout 4 study years during exposure to powder-free gloves. Their atopic status was determined by skin prick testing using a panel of common allergens, and any sensitivity to latex proteins and the cross-reacting food allergens assessed. METHODS: Skin prick testing was carried out on the volunteers using latex, avocado, kiwi, banana, grass pollens, tree pollen, house dust mite and cat dander. Each volunteer completed a questionnaire detailing allergic history and any previous latex exposure. RESULTS: Skin prick testing showed a 65% incidence of atopy in the longitudinal study group. Initial latex skin testing was positive in 3 of the 63 students followed throughout their period of study. Subsequent testing gave a negative result in one student and one declined retesting. The third continued to give a positive response on each testing; she wore only nitrile gloves and remained free of clinical NRL allergy symptoms. No student developed latex sensitivity during the 5 yr of this study. CONCLUSION: Exposure to powder-free latex gloves was not associated with subsequent sensitization over 5 yr in a population with a high atopic incidence.
