Is Your Job Making You Wheezy? GPs Failing To Diagnose 75% Of Patients With Occupational Asthma In The UK

A new report published today in the scientific journal, Occupational Medicine, finds that many people who develop work related are not correctly diagnosed by GPs. Work related factors cause one in ten cases of in adults but an audit of patient records suggests that GPs do not recognise this in three quarters of patients.

Every year up to 3000 people develop asthma because they are exposed to materials at work. A wide range of substances including some workplace chemicals, flour, cutting oils, laboratory animals and insects, enzymes and wood dusts can all contribute to workers getting wheezy symptoms. Vehicle paint-sprayers, bakers, and those who work in the chemical industries are most at risk.

Early diagnosis of and avoidance of further exposure can lead to complete recovery. However, failures to diagnose the condition and delays in accessing specialist advice mean that two thirds of sufferers never make a full recovery.

Researchers at the Institute of Occupational and Environmental Medicine, University of Birmingham conducted an audit of the electronic patient records of working age asthmatics. Occupation was only recorded in 14% of the cases and in nearly all cases (98%) GPs failed to record if they had asked simple screening questions about whether their improved at weekends and on holiday.

, the lead author, said “Most workers with new asthma symptoms present to their GPs first, so it is important for health care professionals working in primary care to recognize when these symptoms might be caused by or related to work. Currently occupational asthma is very costly to the NHS and to society – and an early diagnosis can prevent on-going debilitating symptoms, time off work and financial loss for the worker.”

The Society of Occupational Medicine who published the study urged GPs to always question patients who present with respiratory problems about their job, the materials they work with and whether their symptoms improve when they are away from work.

“Highlighting the prevalence of occupational asthma is absolutely key, as too often work-related factors are overlooked,” said Dr Richard Heron, President of the Society of Occupational Medicine. “About 70% of the UK workforce does not have access to occupational health care. This makes it vital that general practitioners are assessing for potential work-related causes and referring to specialists where appropriate. More importantly, employers need to be aware of those substances that may cause asthma and where possible remove them or minimise exposure.”
