Introduction

Work place.jpg

Occupational Health (OH) refers to the relationship between work and health.

  • OH specialists aim to enhance a worker’s health status, increase the productivity of a workforce, improve business performance and the economy.[1]

Various terms are used to denote this area of rehabilitation. Occupational Health is typically used to refer to individuals in work whereas Vocational Rehabilitation tends to be used when referring to those outside paid employment, but these terms vary across the world.[2]

OH specialists have specific training and experience to understand the link between health and work.[1] This enables them to support both workers and employers. OH focuses on three main objectives:

  • Maintenance and promotion of workers’ health and working capacity
  • Improvement of working environments to ensure that they are conducive to health and safety
  • The development of work organisations/cultures in ways which support health and safety at work, promote positive social interactions and improve productivity[2]

Why is Occupational Health Important ?

Work is said to increase physical and mental health, enhance a worker’s sense of purpose, confidence, self-worth, independence and fulfilment.[3] Return to work post illness or injury should, therefore, be considered as an important outcome measure when exploring treatment options and the support of working age people.[3]

  • Five percent of all sickness absence will become long term (ie it will last more than 4 weeks) and this accounts for almost half of the total working days lost each year.[4]
  • The longer a person is absent from work, the greater the chance that s/he will not return to work.[3] eg. if an individual is absent from work for six months, there is an 80% chance that s/he will be out of work for five years,[5] which comes at significant cost to the individual and society.

Of particular importance to physiotherapists is that alongside “stress, depression and anxiety”, “other musculoskeletal problems” are some of the most commonly reported reasons for long term absence from work.[3]

What does an Occupational Health Specialist Do?

The OH specialist is involved in performing impartial and objective assessments that consider not only what is best for the employee, but also what is best for the employer.[2]

  • Important as an organisation’s success is strongly affected by the health and wellbeing of its workforce.[1]
  • Effectively managing the requirements of both parties is essential to ensure a productive outcome for all.[2]
  • This focus on both the patient and their employer sets OH apart from other areas of physiotherapy, where the focus is usually on the individual.[2]

Not all employees have equal access to OH services. Employees working for larger organisations will be more likely to be able to access these supports, as will those working in the public sector versus those in the private sector,[3] thus it seems important that all physiotherapists consider this area when creating treatment or rehabilitation plans.

Biopsychosocial Model

OH uses the biopsychosocial (or bio-occupational-psycho-social) model rather than the biomedical model:[2]

  • Bio - a focus on the physiological pathology, levels of physical health or disability
  • Psycho  - a focus on thoughts, emotions, and behaviours such as psychological distress, fear avoidance/beliefs and current coping mechanisms
  • Social  - a focus on the social economical, social environmental and cultural factors such as work issues, family circumstances and economy based factors

All these areas are related and must be considered together for effective OH assessment and support.[2]

The Occupational Health Team

The OH team includes health professionals from a variety of backgrounds who work together to enable workers to return/remain in the workplace.

  1. Occupational Health Physicians promote and protect the health and workability of workers. They focus on preventative medicine and management of illness, injury and disability related to the workplace.[2]
  2. Occupational Health Advisors are nurses with specialist training in OH. They often take on a case management role and will perform duties such as new starter health assessments, health surveillance and screening programmes such as audiometry, spirometry, vision screening, hand/arm vibration assessment and shift worker assessment.[2]
  3. Occupational Health Psychologists care for psychological well being of the individual. They are involved in supporting job satisfaction and the effectiveness of the organisation. Their role is diverse and can focus on education and training or one-to-one support and therapy. Similarly they may be involved in advising managers and decision makers on how best to support the mental health and well-being of employees.[2]
  4. Occupational Therapists in the workplace help employees overcome barriers that prevent them from participating in work. These barriers are varied and include issues such as illness, disability, social/institutional or physical environmental issues.[2]
  5. Occupational Health Physiotherapists are often involved in the assessment of return to work, functional rehabilitation, and other clinical treatment services. They may take on health promotion and education roles, risk assessment and training, health promotion activities, as well as being involved in managing long term conditions in the workplace. Physiotherapists working in OH have the scope to develop their own practice in different directions from risk management and interventions through to case management of long term conditions in the work place.[2]

The roles of these professions often overlap and all may be first contact practitioners. They may also be supported by ergonomists, occupational hygienists, health and safety consultants, HR and senior managers.[2]

Relationship of Occupational Health to Physiotherapy

Physiotherapy has been found to be clinically and cost effective in getting people back to work.[5] While not all physiotherapists will become OH specialists, there is a need for all physiotherapists to consider the importance of work factors when assessing patients.[2]

Physiotherapists are well placed to ask questions about work and to set goals focused on return to work. Examples of questions to guide you to assess the impact of an injury on work could include:

  • What work duties are difficult as a result of your injury/condition/disability?
  • What do you feel could be done to help resolve this issue?
  • Which of your work tasks are you currently still able to undertake?[2]

With careful questioning, physiotherapists can develop a picture of how work conditions may be aggravating a patient’s condition.[2] Patients can also provide photos or videos of their work station to enable the physiotherapist to better understand the workplace. Many office workers spend prolonged periods in front of computers/laptops, so physiotherapists can provide information on stands, the use of an external mouse and keyboard, as well as providing postural advice and a simple exercise programme to do at work.[2]

Physiotherapists can also consider blue or yellow flags that may be affecting a worker’s condition or engagement in the workplace. If unable to address all the relevant issues, a physiotherapist can then consider referring on for more specialist OH management.
