Communicating health risk.

Health risk communication is a two way interactive process that involves the exchange of information among interested parties about the nature, magnitude, significance, or control of a risk. Although it has only recently become a topic for scientific research, much has been learned in relation to the strategies and the techniques that contribute to effective health risk communication. In parallel, there has probably never been a time of greater need for effective training in health risk communication. The media and the general public are now very hazard conscious, subsequent to apparently regular events in the areas of public health, safety and environmental issues. Public concern regarding such issues is sometimes much less than experts feel to be appropriate, whilst at other times concern has outstripped the concern of the experts involved. Health professionals trained in the techniques of health risk communication are a vital resource in ensuring that the workforce or the population is properly informed so as to exercise appropriate decisions and actions in relation to hazard and risk.     

The changing role of the occupational physician in the private sector: the Canadian experience

The role of the occupational physician in the private sectoris changing. Fewer large corporations maintain medical departmentsfollowing the ‘downsizing’ trend of the late 1980'sand early 1990's and those that do have extensively redefinedthe duties of the corporate medical director, often extendingthese duties to include responsibility for environmental health.Occupational medical services for employees previously coveredby in-house services are now often provided by outsourcing.The private practice of occupational medicine has become themajor growth area of the speciality in both the US and Canada.These trends have been driven primarily by economic imperativesand new management philosophies; the trend may have gone toofar and a ‘rightsizing’ correction may be in progress.However, it is not clear that corporations in general are derivingthe greatest value they can from their physicians or that thecurrent generation of senior managers is utilizing its healthprofessionals as effectively as they might. This is in partbecause the training, qualifications and capabilities of occupationalphysicians are not well understood. At least as important, however,is persistent confusion over desirable and appropriate rolesthat obscures the potential contribution of the medical professionalwithin a management structure. We suggest that the greatestvalue in occupational medical services may be in the anticipationof risk related to health issues and the flexibility this givesthe organization to manage the problem.     

Band saw injury in a butcher

BACKGROUND: While treating an unusual amputation caused by a meat band saw in a 35-year-old butcher, we sought information from the medical literature that would be useful to other physicians who might encounter similar occupational injuries. METHODS: Using the Medline database and relevant search terms, we reviewed the literature concerning occupational saw blade injuries and porcine microbiology as they related to this injury. RESULTS: Among meat workers using powered cutting equipment, hand injuries and distal fingertip amputations appear to be common. The greatest risk for a wound infection after open exposure to raw pork meat appears primarily related to environmental flora rather than enteric-borne porcine pathogens. CONCLUSIONS: Decision-making strategy when formulating a treatment plan for debridement or reconstruction of saw blade amputations should rely on a detailed understanding of the injury and occupational environment to achieve an optimal patient outcome. When considering operative and antibiotic treatment for porcine meat-related amputation injury, surgeons should adhere to open fracture-related guidelines, since porcine-borne illnesses are most often caused by ingestion rather than transcutaneous inoculation.     

How I address quality and teamwork issues in the occupational health department

To be successful in today's climate an occupational health providerneeds well-trained and motivated staff who are both professionaland focused on delivering quality services that meet the needsof their customers. Achieving this goal is facilitated by havinga clear sense of mission with systems in place within the organizationof the department that support this and encourage continuousimprovement. Good communication, performance measures and teamworkare identified as key elements in realizing the goal of a qualitydepartment. This article, in sharing the experiences of addressingquality and teamwork, discusses important issues relevant tomany occupational health departments.     

The interaction between general practitioners and occupational health professionals in relation to rehabilitation for work: a Delphi study

BACKGROUND: Anecdotally, communication between general practitioners (GPs) and occupational health professionals is poor and acts as a barrier to successful rehabilitation for work. It is not known how widely this view is held by the many stakeholders in rehabilitation for work, or how important the observation is in its effect. METHODS: A Delphi study was conducted by initial semi-structured telephone interview, followed by a three-round collation and feedback of opinion by e-mail. The 25 participants were identified by suggestion within the study process for their position as key informants within a wide range of stakeholders. RESULTS: The process generated a consensus statement which identifies the extremely important nature of rehabilitation for work, the crucial role by GPs, the central role of occupational health professionals in case management and the barrier represented by the often very poor communication between them. CONCLUSION: The way forward is to improve communication by mutual education and understanding and a team approach to rehabilitation strategy. This may be facilitated by the GPs who work in occupational health and disability assessment and the involvement of other health professionals to great benefit for all stakeholders.     

Inequity in occupational health services for government hospital workers in South Africa

South Africa's inequitable public health system is mainly delivered by provincial health departments, and exemplifies the potential and problems of occupational health services in middle-income countries. The occupational health services for 153 265 employees in all of South Africa's 370 provincial hospitals were described and compared. Information was obtained from 303 (82%) hospitals, using a self-completed questionnaire and telephone interviews. Thirty-two per cent of hospitals had an occupational health clinic, but 61% of employees worked in hospitals with a clinic. Occupational health clinics were more likely to be present in larger hospitals, and were strongly associated with provision of primary care and chronic disease services to workers. Thirty-nine per cent of hospitals had a safety officer, 41% had access to an industrial hygienist or environmental health officer, and 80% had health and safety committees, as required by law. While occupational health services were more likely in larger hospitals, workforce size did not explain the marked differences between provinces. The study shows that substantial occupational health services exist, but that important gaps persist, even in wealthier provinces and especially in provinces without coherent occupational health policies.     

Major chemical incidents: bridging the occupational--public health gap

Increasing awareness and concern about possible long-term health effects of exposure to chemicals after major chemical incidents has opened up a new area of public health activity. However, progress is hampered by a lack of low level exposures in potentially highly susceptible subgroups of the populations, and by a lack of expertise in public health. The challenge is to extend the toxicological and epidemiological experience developed in the occupational setting to the community level. To better define the problem population surveillance of acute chemical hazards, first set up in Wales, has been extended throughout the UK, and is also being piloted internationally. Further work is needed to address specific problems of the epidemiological follow-up of populations exposed, the assessment of the psychological consequences at the community level, and risk perception and communication. Organisational arrangements for the public health management of incidents and their sequelae must move beyond short-term funding and market competition and must incorporate the expertise of the occupational disciplines.     

The design of hazard risk assessment matrices for ranking occupational health risks and their application in mining and minerals processing

Two hazard risk assessment matrices for the ranking of occupational health risks are described. The qualitative matrix uses qualitative measures of probability and consequence to determine risk assessment codes for hazard-disease combinations. A walk-through survey of an underground metalliferous mine and concentrator is used to demonstrate how the qualitative matrix can be applied to determine priorities for the control of occupational health hazards. The semi-quantitative matrix uses attributable risk as a quantitative measure of probability and uses qualitative measures of consequence. A practical application of this matrix is the determination of occupational health priorities using existing epidemiological studies. Calculated attributable risks from epidemiological studies of hazard-disease combinations in mining and minerals processing are used as examples. These historic response data do not reflect the risks associated with current exposures. A method using current exposure data, known exposure-response relationships and the semi-quantitative matrix is proposed for more accurate and current risk rankings.     

Compensating occupationally related tenosynovitis and epicondylitis: a literature review

OBJECTIVES: To assess occupational associations with tenosynovitis and epicondylitis, we conducted a systematic literature review. We focused particularly on evidence that might support compensation of these disorders 'on the balance of probabilities'. METHODS: We searched the MEDLINE and EMBASE electronic biomedical databases to 1 January 2005 using combinations of keyword and medical subject headings, and also the references cited in two state-of-the-art reviews from the 1990s. Primary research reports were retrieved and checked for further relevant citations. From each paper, we abstracted a standardized set of information on study populations, exposure contrasts and estimates of effect. RESULTS: We found and summarized 18 papers. In the main, these based analysis on job titles rather than on directly assessed physical activities. Few occupations were studied more than once, however, and there was little consistent evidence of jobs or work activities that carried more than a doubling of risk for either disorder. CONCLUSION: Compensation of occupational illness can be problematic for disorders that are not specific to work and for which there are no distinctive clinical features in occupationally related cases. Attribution can, however, be made on the balance of probabilities if there is convincing evidence that risk is at least doubled in an occupational group. Our review highlights the relative lack of data to support such attribution for tenosynovitis and epicondylitis, and discusses the difficulty of compensating upper limb disorders.     

Lead toxicity

Lead is one of the oldest known and most widely studied occupational and environmental toxins. Despite intensive study, there is still vigorous debate about the toxic effects of lead, both from low-level exposure in the general population owing to environmental pollution and historic use of lead in paint and plumbing and from exposure in the occupational setting. The majority of industries historically associated with high lead exposure have made dramatic advances in their control of occupational exposure. However, cases of unacceptably high exposure and even of frank lead poisoning are still seen, predominantly in the demolition and tank cleaning industries. Nevertheless, in most industries blood lead levels have declined below levels at which signs or symptoms are seen and the current focus of attention is on the subclinical effects of exposure. The significance of some of these effects for the overt health of the workers is often the subject of debate. Inevitably there is pressure to reduce lead exposure in the general population and in working environments, but any legislation must be based on a genuine scientific evaluation of the available evidence.
