Q

Occupational history

A

An occupational history is a chronological list of all patients employment, expanded as necessary to detail any evidence of occupational exposure to potentially hazardous agents and resulting effects on health
Most effective instrument:
-to determine if there is evidence that work is a likely cause of ill health (diagnosis of disease)
-diagnosis will lead to better management or appropriate referral
-for assisting return to work after injury or disease if it helps to identify shortfalls in health or fitness against required standards

A

There must be indication of sufficient occupational exposure
Exposure information on hazards
-type eg chemical substance, noise, radiation
-level and duration of exposure
-when exposed (specific job tasks)
-potential health effects

32
Q

Exposure information

A

Evidence of occupational exposure may be obtained from:
-occupational history
-results of exposure survey at work: personal environmental or biological monitoring data samples
-exposure records: workplace risk assessments

33
Q

Medical tests

A

Reported signs and symptoms may be supported in some cases by suitable tests eg spirometry, audiometry, vision testing, patch testing
Examples:
-extent of hearing loss and type
-allergic reactions to substances used at work
-decrement in lung function

34
Q

Temporality

A

When in relation to exposure do/did the symptoms start

35
Q

Reversibility

A

Do the symptoms improve when no longer exposure
Peak flow variation between workdays and weekends

36
Q

Exposure response

37
Q

Strength of association

A

Do other workers suffer similar symptoms associated with the same exposures

38
Q

Differential diagnosis

A

Non-occupational conditions that have similar clinical features as the occupational disease:

-environmental
-social (smoking, alcohol)
-hobbies, pets
-medical history
-family history/genetic
Need to also consider other employment

39
Q

Additional information for diagnosis occupational disease

A

Minimum intensity level of exposure required to cause disease
Minimum duration of exposure
Maximum latency periods- length of time between from cessation of exposure beyond which it unlikely that the disease can be attributed to work

Return to work

A

A GP is often involved in assessing fitness to return to work RTW
Fundamental questions:
-does the patient want to RTW
-does patient need to be symptom free before RTW
- is some work feasible

51
Q

Moving from ‘sick note’ to ‘fit note’

A

Many people with health conditions can work as they recover from their condition
Work can aid recovery and benefit the employer by reducing sickness absence
Need to focus on what individual can do rather than incapacity
Introduced in 2010 doctor to advise if an employee may be fit to work with some support
Tick Boxes for doctors to use to suggest common ways to help a return to work
Note:
-certification for statutory sick pay (and other benefits)
-advisory (to the patient), not an instruction

52
Q

GPs and OH

A

The patients occupation is not always recorded
The patient is not asked about their work
GPs don’t feel trained to use to fit note and rarely advise someone might be fit
GPs often don’t understand occupational health

53
Q

Aim of the OH assessment

A

Effects of health on work
Effects of work on health
Workplace adjustments/adaptations etc required for employee to work safely
Communicate outcome and recommendations
