Learning Points • Pluses and minuses of work on health • Revisit concepts of hazard and risk • Major UK occupational health problems • Revisit occupational history • Supplemented by small group seminars

Hazard Any exposure that might cause harm
Risk The chance of that harm actually occurring in given circumstances.
HAZARDS/EXPOSURES • Chemical • Physical • Mechanical (ergonomic) • Biological • Psycho-social/organisational

Top Four Illnesses/Diseases? Musculoskeletal, Stress, Respiratory, Skin Problems.
Musculoskeletal Diseases Most common problem: • 1.1 million people/yr • Cost = £5.7 billion/yr
Musculoskeletal Diseases • Most frequent causes include: • Repetitive and heavy lifting • Bending and twisting • Repeating an action too frequently • Uncomfortable working position • Exerting too much force • Working too long without breaks
Occupational Stress Close second! 9.1 million UK workdays lost each year are attributed to stress related illnesses Cost to industry is £3.7 billion Costs for Govt Sick Pay + NHS is £7 billion 20% of workers report high or very high levels of stress at work
Respiratory Work related death due to lung disease (2000): • Mesothelioma 1628 • Asbestosis without meso 186 • Other pneumoconiosis 279 • Byssinosis 4 • Allergic alveolitis 7 • TOTAL 2104
OCCUPATIONAL ASTHMA • Most frequently reported occupational respiratory disease in Great Britain • 1500-3000 new cases a year • 7000 cases of work related asthma when those whose asthma is made worse by work are added • Cost £1.1 billion each year
SWORD reported cases/year • isocyanates 128 • flour or grain dust 80 • glutaraldehyde 49 • wood dust 49 • natural rubber latex 38 • solder/colophony 35 • laboratory animals 32 • glues and resins 30
OCCUPATIONAL ASTHMA • Who develops hypersensitivity is unpredictable • The dose of exposure needed is unpredictable • Hypersensitivity is irreversible • Removal from exposure immediately warning symptoms start may allow complete recovery • Cases must be reported under RIDDOR Scheme
Skin Work-related skin diseases: • Self-reported prevalence = approx 39,000 • Annual incidence reported by specialist doctors = approx 3,900
How Do You Make a Difference? • Prevention (Better than Cure) • Health & Safety Policies • Screening • Surveillance • Treatment • Workplace Adjustment • Redeployment (Change of Work)
What is an Occupational History? An occupational history is a chronological list of all the patient’semployment, expanded as necessary to detail anyevidenceof occupationalexposureto potentiallyhazardous agentsand resultingeffectson health.
Why take an Occupational History? To determine if there is evidence that: work is a likely cause of ill health. work has aggravated existing ill health. health or ill health hasan effect on the capacity for work.
The Occupational History • What do you do for a living? • What do you actually do at work? • What do you work with? • How long have you been doing this type of work? • Do you have more than one job? • Have you done any different kinds of work in the past? • Have you been told that anything you use at work may make you ill? • Has anyone at work had the same symptoms? • Do you have hobbies e.g. DIY or gardening, that may bring you into contact with chemicals? • Is there an occupational health doctor or nurse at your workplace?
