Oasys and Occupational Asthma

This website contains information on Occupational Asthma and a free multi award winning computer program called OASYS, which is used to help diagnose Occupational Asthma from serial peak flow records. Oasys shows further information and downloads for the Oasys program. References is a searchable database of more than 5000 published papers in the field of occupational asthma. Causes shows some of the causes of occupational asthma. The Shield scheme reports some statistics for occupational asthma, mainly in the West midlands region, UK. BOHRF shows the evidence based occupational asthma guidelines for the UK. The interactive Case Histories are a learning resource for interested health professionals. There are also Medics, Specialists, Employers and Worker sections.

Comments for the paper: "Impact of occupational asthma on health and employment status: a long-term follow-up study", 2022, Occup Environ Med
The numbers with continuing employment after diagnosis by SIC is higher than many previous studies, despite the lack of emphasis on this by Italian compensation authorities. There is no information as to how this was achieved. Nearly 80% were still employed at follow-up, most changing their place of work, which was associated with more recovery than those relocated in their original workplace. There was no overall improvement in FEV1 % predicted at follow-up, but some improvement in NSBR and FeNO. This paper has a low follow-up rate (60/204) and finds similar factors relating to poorer prognosis as earlier studies (lower presenting FEV1 and NSBR, longer time exposed after symptoms started, longer latent interval).

Comments for the paper: "Workplace-related inhalation test - Specific inhalation challenge: S2k Guideline of the German Society for Occupational and Environmental Medicine e.V. (DGAUM), the German Soc
These are practical guidelines for occupational challenge testing in Germany, and do not attempt to be evidence-based. They include indications and methods, but omit the need for a control exposure for most patients. The reasons for this are more pragmatic than evidence-based. They are perhaps more appropriate for countries who require a positive SIC for compensation, the tests often carried out after a decision to remove the worker from exposure has been made.

The Website

This website is run by the Oasys research group, part of the Midland Thoracic Society, UK. We are an independent group of clinicians and researchers, and run a clinical service for workers with occupational lung disease as part of the British National Health Service. We have developed the Oasys program to help ourselves and others in the diagnosis of occupational asthma. We have no specific funding, relying on research grants and the enthusiasm of our group. The website is written by Cedd Burge, who receives some funding from the group. The group meets every Friday evening after the occupational lung disease clinic, as shown below.



As a casual user of this site (without logging in or registering) you can view all the information and use all the contact pages. Registered and logged in users (registering is free and we won't abuse your email) can download and use the Oasys program, ask and reply to questions in the forums, leave comments, add new references, add abstracts and full text links to existing references, answer questions in the case histories and provide evidence and suggest questions for future evidence based guidelines.

If you would like to be added to the list of known authors or collaborators then please register with the website (if you have not already done so) and then get in touch from the contact page. Once we have set the page up you will be able to edit it yourself and indicate which references you have written. Your picture will then be displayed along with each of these references.
