The effect on attendance rates for sickness absence assessment of a revised employee information sheet

BACKGROUND: An increasingly high standard of ethical practice is expected of all doctors and in particular those not providing treatment services. AIMS: This case-control study investigated the effect on non-attendance rates for first sickness absence appointments of a new employee information sheet sent to staff from the two largest departments, education and social services, of a large UK local authority. METHOD: An information sheet detailing the ethical standards applying to a local authority occupational health service was developed and sent to all employees referred by their managers as part of the sickness absence management procedures, along with details of their appointment. RESULTS: A reduction of approximately 1/3 in the rate of non-attendance was noted in the intervention group, which was statistically significant for social services referrals. CONCLUSION: This approach may improve the efficiency and effectiveness of occupational health services, as well as helping to achieve the informed consent of employees undergoing occupational health assessment.     

Is service with the parachute regiment bad for your health?

Military parachuting is perceived to be a 'high risk' activity. The estimate of risk should be based on a comparison of injury rates between soldiers who are military parachutists and soldiers who are not military parachutists rather than the rate of injury per parachute descent. Since other aspects of military life also have an inherent risk of injury the risk attributable to military parachuting must be assessed in this context. The aim of this paper is to determine whether Parachute Regiment soldiers have a greater risk of injury as compared with non-Parachute Regiment infantry soldiers by comparing rates of hospital admission and medical discharge between the two groups. Records at the Defence Analytical Services Agency were analysed for the 10-year period 1987-96. The mean rate of hospital admission for Parachute Regiment soldiers was 50.1 per 1,000 and for infantry soldiers was 50.8 per 1,000 [relative risk (RR) = 0.98; 95% confidence interval (CI) = 0.92-1.04). The mean rate of medical discharge for Parachute Regiment soldiers was 4.9 per 1,000 and for infantry the mean rate was 2.8 per 1,000 (RR = 1.76; CI = 1.45-2.15). This study has shown a methodology for comparing occupational exposure to risk that could be extended to other groups if they can be separated by appropriate criteria.     

Ethical issues in occupational medicine practice: knowledge and attitudes of occupational physicians

Views on ethical conduct in occupational medicine practice canvary from country to country and even between occupational healthpractitioners. However, there are many areas of common agreement,and this is apparent on comparing guidance documents on ethicsproduced by several different organizations. The usefulnessof these documents will depend in part on how aware practitionersare of their existence. A standardized questionnaire administeredto 70 occupational physicians in the Netherlands, UK, and Singaporeshowed that there was a lack of awareness of guidance documentson ethics, even for publications from their own countries. Onlyfive of the 70 respondents consulted an ethics document in thepast year. In addition to publications, other avenues were usedfor advice on ethical issues. There was a difference in opinionbetween the physicians from Singapore and those from the twoEuropean countries on whether specific occupational health activitieswere ethical. These findings reinforce the need for internationalguidance on ethics to take into account differences in attitudesand practice between countries. On many issues there was nounanimity of opinion, even between occupational physicians fromthe same country. This may be an indication of the complexityof ethical matters, and provides a rationale for publishingguidance on ethics in occupational medicine.     

Biomarkers, screening and ethics

Rapid scientific advances, such as those in biomarker technology,have made a significant impact on the ethics and practice ofoccupational health. Biomarkers are extensively used in occupationalhealth practice. In the pre-employment stage, preventive orpredictive testing can be performed. Preventive testing aimsto avert accidents that may occur if a medically unfit workerundertakes a job that he is unable to perform. For safety sensitivejobs, routine testing of a worker's functional capacity in theactual job would suffice in most cases. However, a recentlyquotes application of a test is the screening for mutationsof the cardiac myosin-heavy chain and troponin genes among asymptomaticpersons with a family history of sudden death from hypertrophicobstructive cardiomyopathy. Predictive testing hopes to forecastthe risk of a worker developing an illness. The aims may vary.One aim may be to exclude a susceptible worker from workingin a hazardous environment. Another aim may be to avoid employmentof a worker who is likely to develop an illness which couldlead to higher employer health care costs. A pertinent questionto consider is whether the test undertaken is to benefit theindividual or to fulfil some administrative or financial need.Among exposed workers, screening may be conducted for biomarkersof exposure or effect. As the aim is to prevent the onset ofclinical illness, the physician must take responsibility forinitiating requests for screening. The appropriate responseto the effect of technical and societal advances on ethics isthe updating of ethical guidelines by the profession. However,in the context of unvalidated biomarkers being used for screening,it may be necessary to require a regulatory body to ensure thatthe tests are accurate and effective, and that they are notused to discriminate against individuals.     

Occupational health management: an audit tool

BACKGROUND: Organizations must manage occupational health risks in the workplace and the UK Health & Safety Executive (HSE) has published guidance on successful health and safety management. AIMS: This paper describes a method of using the published guidance to audit the management of occupational health and safety, first at an organizational level and, secondly, to audit an occupational health service provider's role in the management of health risks. The paper outlines the legal framework in the UK for health risk management and describes the development and use of a tool for qualitative auditing of the efficiency, effectiveness and reliability of occupational health service provision within an organization. The audit tool is presented as a question set and the paper concludes with discussion of the strengths and weaknesses of using this tool, and recommendations on its use.     

Ethical requirements for occupational health research--compliance arrangements for a single company in relation to a recent major nuclear industry study.

The media coverage given to occupational health studies in the field of ionizing radiation has, on occasion, been the cause of very real distress to radiation workers and their families. In response to this situation the Chief Medical Officers of the major UK nuclear companies developed an ethical policy for future involvement in research, based on the duty of care which researchers owe to a key customer of such studies: the worker. The policy consists of four principal elements: medical confidentiality; worker information; worker consent and the guarantee of the availability to the workers of pre-publication knowledge of the results. The policy issued in 1991/92 has achieved growing acceptance among researchers and medical journals, though the medical officers involved have been aware of some scepticism, particularly in relation to the practicalities of the dissemination of pre-publication information. The Record Linkage Study published in November 1997 marked a major piece of research work involving data from 120,000 radiation workers that had been carried out since the development of the policy. This paper reports on the successful compliance arrangements to meet the ethical requirements of that study within a single UK nuclear company, and is published to demonstrate that with commitment from researchers, the journal and occupational health staff such ethical requirements, and particularly the need for pre-publication information can be met in full.     

A risk-based system to penalize and reward line management for occupational safety and health performance

Penalizing line management for the occurrence of lost time injuries has in some cases had unintended negative consequences. These are discussed. An alternative system is suggested that penalizes line management for accidents where the combination of the probability of recurrence and the maximum reasonable consequences such a recurrence may have exceeds an agreed limit. A reward is given for prompt effective control of the risk to below the agreed risk limit. The reward is smaller than the penalty. High-risk accidents require independent investigation by a safety officer using analytical techniques. Two case examples are given to illustrate the system. Continuous safety improvement is driven by a planned reduction in the agreed risk limit over time and reward for proactive risk assessment and control.     

Increased risk of asthma among Finnish construction workers

AIM: To determine the risk of asthma among 7891 Finnish construction workers in the Pirkanmaa Region of southern Finland. METHOD: Retrospective cohort study of hospital records of the Tampere University Hospital. A population of Pirkanmaa paper mill workers (n=2686) and the Pirkanmaa working age population (n=252,500) served as reference populations. RESULTS: There were 147 new cases of asthma among the construction workers in 1991-1995. The annual rate was 37 per 10,000 workers and the odds ratio was 2.1 [95% confidence interval (CI)=1.2-3.6] for the women and 1.8 (95% CI=1.5-2.2) for the men when compared with the general working age population. In general, the risk of asthma among the paper mill workers did not differ from the risk of asthma among the general working age population. The construction workers had an increased risk for asthma, although the number of reported cases of occupational asthma was lower for the construction workers than for the paper mill workers or for the working population. CONCLUSION: Construction work, especially dusty tasks, was associated with an elevated risk of asthma. Thus the effect of exposure to irritant agents may have a role in the development of asthma among construction workers. For the most part, these cases of asthma do not meet the criteria for occupational asthma because the specified causal agent can not be defined. The aetiologic agents and mechanisms of asthma in construction work should be clarified for preventive measures.     

Occupational safety risk management in Australian mining

In the past 15 years, there has been a major safety improvement in the Australian mining industry. Part of this change can be attributed to the development and application of risk assessment methods. These systematic, team-based techniques identify, assess and control unacceptable risks to people, assets, the environment and production. The outcomes have improved mine management systems. This paper discusses the risk assessment approach applied to equipment design and mining operations, as well as the specific risk assessment methodology. The paper also discusses the reactive side of risk management, incident and accident investigation. Systematic analytical methods have also been adopted by regulatory authorities and mining companies to investigate major losses.     

Air blast circuit breaker noise and hearing loss: a multifactorial model for risk assessment

The assessment of the risk to hearing from impulse noise exposure may be a problem for the occupational physician because existing legislative and international noise exposure standards deal primarily with continuous noise, and are not valid in excess of the peak exposure limit of 200 pa (140 dB). Noise exposure in excess of this level, for example that due to firearms, is frequently perceived as harmful, but this is not necessarily the case, as impulse noise standards do, in fact, allow exposure with a maximum in the order of 6.3 kPa (170 dB). To illustrate this, a cross-sectional group of electrical transmission workers have been studied who were exposed to significant levels of impulse noise from air blast circuit breakers and firearms. Important hearing loss factors have been identified by means of a specially designed questionnaire. Using the Health & Safety Executive definition, the risk of hearing loss was determined by calculating prevalence odds ratios (ORs) for exposure to these factors. The OR for those with fewer than eight unprotected air blast circuit breaker exposures was 2.27 (95% confidence interval (CI), 1.01-5.08), whilst for those with more than eight exposures the OR was 2.10 (95% CI, 0.97-4.54). For firearm exposure, ORs of 1.61 (95% CI, 0.95-2.74) were noted in the medium exposure group and 2.05 (95% CI, 1.08-3.86) in the high exposure group. When all the factors were included in the model, the most significant factor was age. The study gives support to the impulse noise exposure criteria, confirming the borderline risk from air blast circuit breaker noise exposure and the relative safety of moderate gunfire exposure.     

The impact of educational interventions on primary health care workers' knowledge of occupational exposure to blood or body fluids

AIM: To assess the impact of educational interventions on primary health care workers' knowledge of management of occupational exposure to blood or body fluids. METHODS: Cluster-randomized trial of educational interventions in two National Health Service board areas in Scotland. Medical and dental practices were randomized to four groups; Group A, a control group of practices where staff received no intervention, Group B practices where staff received a flow chart regarding the management of blood and body fluid exposures, Group C received an e-mail alert containing the flow chart and Group D practices received an oral presentation of information in the flow chart. Staff knowledge was assessed on one occasion, following the educational intervention, using an anonymous postal questionnaire. RESULTS: Two hundred and fifteen medical and dental practices were approached and 114 practices participated (response rate 53%). A total of 1120 individual questionnaires were returned. Face to face training was the most effective intervention with four of five outcome measures showing better than expected knowledge. Seventy-seven percent of staff identified themselves as at risk of exposure to blood and body fluids. Twenty-one percent of staff believed they were not at risk of exposure to blood-borne viruses although potentially exposed and 16% of exposed staff had not been immunized against hepatitis B. Of the 856 'at risk' staff, 48% had not received training regarding blood-borne viruses. CONCLUSIONS: We found greater knowledge regarding management of exposures to blood and body fluids following face to face training than other educational interventions. There is a need for education of at risk primary health care workers.     

Ethical issues among Finnish occupational physicians and nurses

A postal survey was conducted among 200 Finnish occupational physicians and nurses on their ethical values and problems. Both groups considered 'expertise' and 'confidentiality' as the most important core values of occupational health services (OHS) corresponding with newly published national ethical guidelines for occupational physicians and nurses in Finland. Nearly all respondents had encountered ethically problematic situations in their work, but ethical problems with gene testing in the near future were not considered likely to occur. Only 41% of the nurses and 36% of the physicians had received some training in the ethics of OHS, and 76% of all respondents never used available ethical guidelines. According to the results, even if ethics play a vital role in OHS, the ability to critically evaluate one's own performance seems quite limited. This creates a need for further training and more practicable national guidelines.     

Occupational health and safety curricula: the factors that decide -an Australian experience

Societal, economic and other changes in recent years have resulted in both an increased level and diversity of education and training in occupational health and safety in Australia. Consideration has been given to the key skills and knowledge required by those who take tertiary level courses and who practise as specialists and generalists in the field of occupational health and safety. The curricula and mode of implementation of these courses are determined by the needs of employers, increased emphasis on quality management systems, the prevailing work climate including information technology, communication and legislative requirements all in the context of a rapidly changing tertiary education system.     

The prevalence of musculoskeletal troubles among car drivers

In order to explore the relationship between car driving and musculoskeletal troubles, a cross-sectional structured-interview survey of low- to high-mileage drivers (including individuals who drove as part of their job) was conducted based on the Nordic Musculoskeletal Questionnaire. The results clearly showed that exposure to car driving was associated with reported sickness absence due to low back trouble and that those who drive as part of their job appear to be more at risk from low back trouble than those whose jobs primarily involve sitting (not driving) and standing activities. The frequency of reported discomfort also increased with higher annual mileage. In addition, drivers of cars with more adjustable driving packages had fewer reported musculoskeletal troubles. This identifies an urgent need for the training of managers of fleet vehicles in the importance of developing measures to reduce this problem, for example, the selection of an individual's car with respect to comfort and postural criteria.     

AIDS Programmes at the Workplace: A Scoresheet for Assessing the Quality of Services

Little data is available on the extent or comprehensivenessof AIDS prevention activities at South African workplaces. Across-sectional postal survey was performed of all members ofthe local occupational health nursing association in the areaof greater Cape Town in 1994 to assess the quality of such programmes.Use was made of an index to score services based on their comprehensiveness,using criteria based on recommendations previously identifiedin the South Africa literature on AIDS control. The presenceof a workplace policy on AIDS was the strongest predictor ofhigh quality AIDS prevention activities. Substantial numbersof companies reported sending staff for HIV-related training,and the presence of training was non-significantly associatedwith higher quality services with regard to HIV prevention.Treatment of sexually-transmitted diseases (STDs) was reportedin slightly over half of the sample. Given the central importanceof STD treatment for the prevention and control of AIDS, improvementsin STD management at the workplace may significantly assistattempts at the public health control of the HIV epidemic. Inaddition, worker involvement in the planning, management andimplementation of AIDS prevention activities is also limitedat present and needs attention. Recommendations for the useof a scoring system to promote evaluation of AIDS programmesin the workplace are made.     

Psychosocial risk assessment: problems and prospects

Health and safety legislation now requires organizations to undertake risk assessments for psychosocial hazards in the workplace. Despite this, there is relatively little guidance on what constitutes a psychosocial risk assessment and how one should be conducted. The approaches that do exist are not without problems. This paper examines some of the difficulties with current approaches and looks at possible areas for development to improve understanding and performance in this important area of health and safety management.     

Genetic screening--uses, potential abuses and ethical issues

Potential uses, abuses and control of genetic screening techniquesare discussed and the ethical issues arising from their useare compared with those for existing health screening practices.The main emphasis is upon issues affecting employment but morewide ranging implications are also touched upon. Although thecurrent policy of various bodies is described, the views expressedare personal.     

Peer-group risk assessment: a post-traumatic management strategy for hierarchical organizations

BACKGROUND: Organizations have moral and legal duties to consider the psychological needs of their workforce following exposure to potentially traumatic events related to the workplace. Additionally, it makes economic sense to avoid loss of valuable personnel to the effects of psychological trauma. There have been attempts to provide a range of psychological interventions for staff after exposure to potentially traumatizing events, but recent evidence-based medicine publications have questioned their effectiveness and, indeed, some studies show that single-session psychological debriefings may be harmful. AIM: This paper presents a post-traumatic management strategy based upon peer-group risk assessment which was developed by the British military and is in use with other hierarchical organizations. The presented model keeps employees functioning after traumatic events and provides support and education to those who require it. Additionally, the strategy aims to identify those who are unable to cope after potentially traumatizing events and aims to refer them for early intervention, which has been shown to be of benefit.     

New stressors, new remedies

This paper looks at the stressors prominent in the workplace at the end of the 20th century--increases in workload, falls in social support, uncertainty and violence. It considers some of the pressures that have created these stressors and some of the interventions used to combat them; for example, better teamworking, different management style, an emphasis on quality, a more accurate analysis of the burgeoning costs of stress to organizations, and an increasing appreciation that parental stress affects children negatively and so makes our future society more at risk. It considers the rising emphasis on the individual role in stress, and on the increase in counselling services. It concludes that occupational health services have a very important role to play not only in providing secondary interventions but also in influencing preventive measures.
