Occupational Health: Core Areas of Knowledge and Competence

OHA’s can contribute by helping managers to manage sickness absences more effectively. The nurse may be involved in helping to train line managers and supervisors on how to use the OH service best, how to refer staff, what type of information will be required, and what to expect from occupational health. By developing transparent referral procedures, ensuring that medical confidentiality is maintained and that the workers’ rights are respected, the OHA can ensure that employees referred for assessment due to sickness absence are comfortable with the process.

OH, nurses, with their close relationship with workers, knowledge of the working environment, and trends in ill-health in the company, are often in a good position to advise management on preventing sickness absence. In my experience, referral to General Practitioners has limited use for work-related issues. It gains the best results by informing the GP and referring to a specialist occupational physician.

Planned rehabilitation strategies can help ensure a safe return to work for employees absent from work due to ill health or injury. The nurse is often the key person in the rehabilitation program who will, with the manager and individual employee, complete a risk assessment, devise the rehabilitation program, monitor progress, and communicate with the individual, the OH physician, and the line manager. Nurses have also become involved in introducing proactive rehabilitation strategies that aim to detect early changes in health before such conditions result in absence from work.

Improving and sustaining working ability benefits many groups, individuals, organizations, and society, as costly absence and other health care costs are avoided. In many cases, the OH nurse has to work within the organization as the client’s advocate to ensure that managers appreciate the value of fully improving the workforce’s health. OH, nurses have the skills necessary to undertake this work and may develop areas of special interest.



The occupational health nurse may develop proactive strategies to help the workforce maintain or restore workability. New workers, older workers, women returning to work following pregnancy, or workers who have been unemployed for a prolonged period may benefit from health advice or a planned program of work-hardening exercises to help maintain or restore their workability even before any health problems arise. Increasingly the problems faced by the industry are psychosocial, and these can be even more complex and costly to deal with. OH nurses, working at the company level, are in a good position to advise management on strategies that can be adopted to improve the psychosocial health and wellbeing of workers.

Health and Safety

The OHA can have a role to play in developing health and safety strategies. Where large or high-risk organizations have in-house health and safety specialists, the OHA can work closely with these specialists to ensure that the nurse’s expertise in health, risk assessment, health surveillance, and environmental health management is fully utilized in the health and safety strategy. Occupational health nurses are trained in health and safety legislation, risk management, and the control of workplace health hazards. Therefore, they can contribute to the overall management of health and safety at work, with particular emphasis on ‘health’ risk assessment.

Hazard identification

The nurse often has close contact with the workers and is aware of changes in the working environment. Because of the nurse’s expertise in the effects of work on health, they are in a good position to be involved in hazard identification. Hazards may arise due to new processes or working practices or from informal changes to existing procedures and working practices that the nurse can readily identify and assess the likely risk from. This activity requires pre-supposed regular and frequent workplace visits by the occupational health nurse to maintain up-to-date knowledge and awareness of working processes and practices.

Risk assessment

A risk management approach is increasingly driving legislation in Europe. OHAs are trained in risk assessment and risk management strategies. Depending upon their level of expertise and the complexity involved in the risk assessment, the nurse can undertake risk assessments or contribute towards the risk assessment by working closely with other specialists.

Advice on control strategies

Having been involved in hazard identification and risk assessment, the occupational health nurse can provide advice and information on appropriate control strategies, including health surveillance, risk communication, monitoring, and the evaluation core of control strategies within the limits of their education and training.

Research and the use of evidence-based practice

Specialist OHAs utilize research findings from various disciplines in daily practice, including nursing, toxicology, psychology, environmental health, and public health. The principal requirement for occupational health nurses in practice is that they have the skills to read and critically assess research findings from these different disciplines and to be able to incorporate the results into an evidence-based approach to their practice. Research in nursing is already well established. There is a small but growing body of evidence created by occupational health nursing researchers investigating occupational health nursing practices.

OHAs should ensure access to and the skills necessary to base their practice on the best available evidence. At the company level, occupational health nurses may be involved in producing management reports on, for example, sickness absence trends, accident statistics, assessment of health promotion needs, and evaluating service delivery and the effectiveness of occupational health interventions. The role’s important aspects are research skills and the ability to transfer knowledge and information from published research to practice.
