Occupational health in the USA in the 21st century

Comparable to the confusion encountered in the birth of the machine age is the perplexing reconfiguration of the United States' health care system. Paralleling the advances in medicine have been the divesting mergers and downsizing of industry, coupled with globalization, which have released millions of long-time workers. The labour contingent is changing, with the addition of great numbers of women and immigrant workers, and the manufacturing economy has become one of service and information. Serving the occupational health (OH) needs of such a force have been the professional societies of physicians, nurses, and industrial hygienists, with their members providing care in a broad variety of facilities. It is possible that a national organization, including all these disciplines, would have a greater voice in the protection of workers' health. Immediate leadership of an occupational health service (OHS) can be rotated among the disciplines, so that competition for primacy among the professionals would end. The new workforce demands culture sensitivity among OH personnel and polylingual capabilities may be demanded in the future. Management skills will be required of all in OH, and greater participation of employees in OH policy will characterize the decades ahead. Nearly neglected up to now, occupational mental health programming will be required to meet the real needs of workers, and to counter the move to outsource OH services, where little patient contact results. Behavioural safety, total quality management, and application of the rapidly developing technologies in health care will define the 21st century efforts in OH. Remaining issues, such as violence, telecommuting injuries, the inclusion of alternative medicine, and women's health, among others, will see carry-over for resolution into the year 2000.     

Communication between an occupational physician and other medical practitioners--an audit

Four hundred and seventy-two consecutive referral episodes relatingto 386 patients attending the Occupational Health Departmentof a general teaching hospital were analyzed to evaluate thefrequency, content and effect on management of communicationsbetween the occupational physician and other doctors. In all,250 episodes (53%) were associated with such a communication.The likelihood of a communication was strongly influenced byreason for referral, particularly in respect of long or shortterm sickness absence; univariate odds ratios (OR)=10.58, 95%Cl=8.13–27.08) and 2.65, 95% Cl=1.55–4.60) respectively;a medical diagnosis of psychiatric illness (OR=3.17, 95% Cl=1.69–5.97));and by number of consultations. Communication was also morelikely when the occupational outcome was ill health retirement,rehabilitation in work or modified work. Ninety-eight per centof specific requests for information or an opinion eliciteda reply. Information received from other doctors influencedthe occupational health physician's management in 52 referralepisodes (20%). Specific action by GPs as a result of communicationwas documented in 54 and by specialists in 37 episodes. Theimportance of communication between occupational health physicianand other doctors in the occupational health process is confirmed.     

NHS occupational health services in England and Wales--a changing picture

AIMS: To establish the extent of doctor input to occupational health (OH) service provision in the UK National Health Service (NHS) in 2001 and to compare this with inputs in 1998. METHOD: A postal questionnaire was used to obtain information from OH medical staff employed by the NHS in England and Wales. RESULTS: The NHS OH service has seen an increase between 1998 and 2001 in the amount of doctor time per employee. Doctors tend to work now for more sessions per week. The proportion of doctors holding specialist qualifications has also increased. An increased number of NHS employees now have access to consultant care for occupational medicine. OH departments increasingly tend to provide services to employees beyond the NHS and are thereby able to generate income to further the development of the service. CONCLUSIONS: Steady progress is being made in improving the provision of OH services within the NHS. However, substantial variation exists in the apparent level of access to such provision. The government policy for all NHS staff to have access to a consultant-led service is not yet met. NHS Plus will impact on this picture and deserves study in the future.     

Problematic or practical? Professional body occupational health guidelines

This paper focuses upon conflict between professional and managerial values in an occupational health setting. Findings are presented which suggest that the guidelines issued by UK occupational health professional bodies (describing the duties and responsibilities of occupational health professionals), have been perceived by professionals as being impractical because they tend to focus on the theoretical role of the professional at the expense of the reality of the experienced role. The paper concludes that the problem does not actually lie with the guidelines, but with the perception of the guidelines. It is suggested that this problem can be addressed by empowering occupational health professionals to interpret and tailor the guidelines to suit their particular working environment. In addition, encouraging occupational health professionals to pro-actively market their role, will result in awareness raising amongst the managers for whom they work who often have inappropriate expectations of the occupational health professionals.     

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.     

Charging for NHSPlus: an inferential study based on the internal provision of occupational health services within the National Health Service

BACKGROUND: 'NHSPlus' was conceived as a national agency that would provide occupational health services to organizations, for a fee, without imposing any financial burden on the taxpayer. This self-funding requirement brings into focus the resource implications for such a service and the determination of the charges to be made to external clients. AIM: The existing provision of occupational health services to >100000 National Health Service (NHS) staff by 13 NHS occupational health services of various sizes was analysed, with the objective of determining an appropriate charge-out rate to third parties. METHOD: Two focus groups were questioned on their work external to the NHS. Data collected on the allocation of doctors and nurses to occupational health services in relation to the number of NHS clients serviced were used to investigate the nature of the resourcing relationship using regression analysis. RESULTS: The relationship was found to be stable enough to provide a good estimate of staff requirements (the key resource requirement). Combining this with costing information allowed inferences to be drawn concerning the economic cost and hence the break-even rate of charge for the service. This was then compared with the employer charge rates in the NHSPlus published case studies. CONCLUSIONS: The results suggest that the per capita charges to external clients are lower than the per capita cost of internal occupational health provision within the NHS, raising questions about the viability of the service.     

Good medical practice: guidance for occupational physicians

Following a catalogue of serious, highly publicized medical misdemeanours, the General Medical Council (GMC) has introduced plans for a new system of medical licensing in the UK called 'revalidation'. Under this, the onus will fall on individual doctors, including occupational physicians, to demonstrate their continuing fitness to practice. Doctors will need to show that they meet basic minimum standards in terms of the care they provide, their own continuing professional development, and other aspects of professional life like probity and ethical behaviour. As part of the process, the Faculty of Occupational Medicine, Royal College of Physicians, has produced its own guidance on good medical practice for occupational physicians, following an extensive consultation exercise. This paper summarizes the background to the initiative, the development process and the standards that have been recommended to aid professional accountability.     

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.     

Psychological and occupational predictive factors for back pain among employees of a university hospital in southern Spain

OBJECTIVES: To identify the individual and occupational factors that are predictors for low back pain among the employees of a university hospital in southern Spain. METHODS: A transverse study was conducted in which the population used was the hospital employees who volunteered to participate. The information was obtained by using a questionnaire, which included demographic and anthropometric variables, habits, characteristics of the work done, and of any pain experienced. The mental health condition of subjects was measured using the GHQ-28, using a score of > or = 6 as the cut-off point. To study the variables associated with pain, crude odds ratios (ORs) were calculated (+/- 95% CI) and adjusted according to a logistic regression model. RESULTS: One thousand one hundred and four subjects participated in the study but only 890 of these completed the questionnaire in full (rate of response, 35.7% of total employees). The population studied was notable for the high proportion of women, for subjects > 41 years of age, and subjects who undertook little or no physical exercise. In addition, according to the GHQ-28 test, 29.9% of the total were 'probable psychiatric cases'. The crude ORs were high in all the occupational categories in comparison with the doctors, with the exception of the maintenance, cleaning, and catering group. They were also higher among women, among subjects with poor mental health, and among women with one or more children. The adjusted ORs showed that having a GHQ-28 score of > or = 6, and belonging to the auxiliary technician category, were independent risk factors for suffering low back pain. Being older than 41 years and in temporary employment were protective variables. CONCLUSIONS: The presence of probable mental illness is the variable most strongly associated with the presence of low back pain in the population studied. Its diagnostic confirmation and appropriate treatment could contribute to reducing the prevalence of vertebral pains in this occupational group.     

Occupational exposure and health problems in small-scale industry workers in Dar es Salaam, Tanzania: a situation analysis

BACKGROUND: Workers in informal small-scale industries (SSI) in developing countries involved in welding, spray painting, woodwork and metalwork are exposed to various hazards with consequent risk to health. Aim To assess occupational exposure and health problems in SSI in Dar es Salaam, Tanzania. METHODS: Focused group discussions (FGD) were conducted among SSI workers. Participants were assessed for exposure to occupational and environmental hazards, the use of protective equipment and health complaints by interview. The findings were discussed with participants and potential interventions identified. RESULTS: Three hundred and ten workers were interviewed (response rate 98%). There was a high level (>90%) of self-reported exposure to either dust, fumes, noise or sunlight in certain occupational groups. There was low reported use of personal protective equipment. There was a high level of self-reported occupational health problems, particularly amongst welders and metalworkers. Workers reported their needs as permanent workplaces, information on work related hazards, water and sanitation, and legislation for SSI. CONCLUSIONS: In SSI in Tanzania, our study suggests that workers have high levels of exposure to multiple health hazards and that use of protective equipment is poor. This group of workers warrants improved occupational health and safety provision.     

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.     

A survey of the delivery and uptake of influenza vaccine among health care workers

During the 1990s, policies for immunizing fit health care workers against influenza varied between National Health Service (NHS) employers and the uptake of influenza vaccine by NHS staff was poor. In light of recent Department of Health recommendations to immunize key health care staff against influenza, we explored the possible reasons for poor uptake and assessed the impact of an intensive promotion campaign on vaccine acceptance. Among 290 doctors and nurses, the main perceived barriers to influenza immunization were difficulty with practical access to vaccine and lack of time to attend. Following intensive promotion and improved local access to influenza vaccine, the uptake among health care workers was approximately doubled. However, the overall proportion of staff immunized was low (5%) and the immunization rate among medical staff was particularly poor (2%). The practical implications for influenza immunization campaigns aimed at health care workers are discussed.     

Occupational health provision and health surveillance in the semiconductor industry

AIMS: To identify the nature of occupational health provision in UK semiconductor-manufacturing plants. To identify the level of industry compliance with legal health surveillance requirements. METHOD: A national inspection programme was carried out by Health & Safety Executive inspectors using a developed protocol. RESULTS: A wide range of occupational health provision was identified from none to use of an accredited specialist. The majority of work was of a reactive nature even where there was specialist occupational health input. Seven companies were identified as not meeting legal compliance and one as having unacceptable compliance for health surveillance. CONCLUSIONS: The spectrum of occupational health provision was very wide. Where health surveillance was provided, it was poorly targeted with limited interpretation and feedback to management.     

The general practitioners' view

General practitioners have patients on their lists who work in a variety of occupations, but the doctor is most unlikely to have had any training in occupational medicine. As a result, occupational causes for illness are rarely considered by GPs. Little contact occurs between occupational health physicians and GPs leading to a lack of understanding of the occupational physician's role. These two factors, when combined, may lead to patients receiving sub-optimal treatment. This could be remedied by better undergraduate and postgraduate training, and by greater professional contact.     

Influence of work environment on emotional health in a health care setting

BACKGROUND: Radical changes are taking place in health care services and might be expected to cause job dissatisfaction, absenteeism, somatic complaints and mental health problems. Research in this area is limited and focused primarily on nurses. AIM: To understand the impact of the work environment on the emotional health of doctors and nurses in a general hospital setting. METHODS: Cross-sectional study using self-reported questionnaires including the General Health Questionnaire, the Posttraumatic Stress Disorder (PTSD) Checklist for Civilians, the Trauma Experiences and Work Environment Scale. RESULTS: The response rates for the study were 28% (60) for doctors and 54% (431) for nurses. Whilst the prevalences of psychiatric disorder, anxiety, depression and PTSD were higher for doctors compared with nurses, this was not statistically significant. Both groups reported witnessing someone badly injured or killed as their most distressing experience (doctors 46% versus nurses 41%). Using multiple logistic regression, significant predictors of emotional health was task orientation for doctors (OR = 1.96, 95% CI = 1.1-3.6), and PTSD (OR = 17.2, 95% CI = 6.0-49.6), work pressure (OR = 1.2, 95% CI = 1.01-1.4) and innovation (OR = 0.81, 95% CI = 0.70-0.94) for nurses. CONCLUSION: The prevalence of psychiatric disorder among the doctors and nurses was similar to that in Britain. Elements of the work environment did impact on the emotional health of health care workers. Organizational development initiatives should include employee mental health issues in order to create a more positive work environment.     

Incidence and suspected cause of work-related musculoskeletal disorders, United Kingdom, 1996-2001

BACKGROUND: Musculoskeletal conditions are the most common self-reported work-related disease, with high costs incurred from long-term disability. In the United Kingdom, occupational physicians and rheumatologists have been reporting new cases of work-related musculoskeletal disorders to voluntary surveillance schemes since 1996. AIMS: To estimate population incidence rates for work-related musculoskeletal disorders reported by rheumatologists and occupational physicians by occupation and industry, in relation to tasks and movements suspected as causal. METHODS: Estimated average annual incidence rates were calculated for nine main job categories and eight industrial groups; Labour Force Survey figures were used as the denominator for rheumatologists, and a special survey for the occupational physicians. These were then related to tasks and movements reported as causal. RESULTS: Between October 1997 and the end of 2001, an estimated 2,599 new cases/year were reported by rheumatologists, and from January 1996, 5,278 cases/year by occupational physicians. Average annual rates overall were 94 per million for rheumatologists and 1,643 per million for occupational physicians (a 17-fold difference). Jobs at highest risk for the upper limb were primarily clerical, craft-related and machine work. Tasks associated with upper limb disorders and with neck and back problems were predominantly keyboard work and heavy lifting, and in craft-related occupations with gripping or holding tools. CONCLUSIONS: Jobs at risk and the associate tasks were identified which should assist prevention, but the extent to which these factors were causal or aggravating previous injury requires further study. The much higher rates reported by occupational physicians reflect, in part, the type of industries they served.     

The perceptions of occupational health in primary care

AIM: A random sample of general practitioners (GPs), practice nurses (PNs) and practice managers (PMs) in Sheffield and Manchester was recruited into a study to evaluate the perceptions of occupational health (OH) in primary care. METHODS: Qualitative data were collected using focus groups with three groups of primary care sector professionals. Quantitative data were collected nationally from 295 GPs using a postal questionnaire. RESULTS: GPs and PNs had minimal OH training, and 60% of GPs reported constraints in addressing OH matters with patients. The lack of referral routes (63 and 67%, respectively) was also seen as a barrier. OH was regarded as a speciality, and primary care professionals preferred to refer patients with OH problems to specialist centres because they perceived barriers to their dealing with the issues. A total of 74% of GPs surveyed thought that speedier access to secondary care would help them to address OH problems. CONCLUSIONS: This study has identified some of the problems associated with delivering OH through primary care. It also demonstrated a need for greater emphasis on OH education in medical and nurse training, and a need for better advice for GPs, PNs and PMs regarding support services for OH.     

Disability management through positive intervention in stakeholders' information asymmetry. A pilot study

BACKGROUND: One increasingly attractive hypothesis to account for prolonged sickness absence from work is the presence of 'information asymmetry' among stakeholders. Information asymmetry refers to a situation in which critical information is not (appropriately) exchanged, in this case among those involved in disability management. AIM: The purpose of this study was to intervene positively in the information asymmetry that currently exists between social insurance physicians and occupational physicians in Belgium. METHODS: We developed a novel model aimed at improving information exchange, and a pilot study protocol based on the model. Our first objective was to investigate feasibility of implementing the study protocol. Our second and main objective was to obtain preliminary results on whether improving information exchange between physicians would facilitate work resumption of employees out on sickness absence. RESULTS: Of 126 patients recruited, 91 were eligible and assigned to one of two groups: a control group, whose physicians used the standard Belgian evaluation protocol, and an intervention group, whose physicians used our new protocol. Outcome parameters from the 15 patients assigned to the intervention group revealed that enhanced inter-physician information exchange produced favourable work resumption rates (73%), suggesting that both the model and study protocol show promise. CONCLUSIONS: The issue of sharing information among all stakeholders involved in disability management is an important one. Moreover, professional reintegration of employees after a sickness absence is universally important to occupational health practitioners. Our preliminary results suggest that reducing information asymmetry among physicians should be investigated further in larger intervention trials.     

Vocational rehabilitation of locomotive engineers with ischaemic heart disease

BACKGROUND: There is resistance among railway companies and their occupational health services to rehabilitating locomotive engineers with ischaemic heart disease to their former driving work. AIM: To study the outcome of vocational rehabilitation for locomotive engineers with ischaemic heart disease. METHODS: In seven European countries, selected locomotive engineers with ischaemic heart disease were compared to a matched group of healthy engineers. At the end of each calendar year between 1990 and 1999, questionnaires were completed by local occupational health physicians to provide information on accidents, incidents (professional mistakes), sick leave, (recurrent) cardiac events, death and early retirement. We used the life table method with five follow-up years to calculate the risk of accidents, incidents and recurrent cardiac events. RESULTS: The accident rate for the cardiac group was 3.8 accidents per 100 person-years, as compared to a rate of 6.0 in the reference group. The rates for incidents were 0.9 and 2.0, respectively. Neither of these differences were statistically significant. The duration of sick leave was significantly longer among the cardiac group than it was among the reference group, but only in the first follow-up year. Thirteen recurrent cardiac events occurred in the cardiac group, as compared to a single cardiac event in the reference group. There was no difference in the proportion of retirement cases. One engineer in each of the two groups died of cardiac disease. CONCLUSIONS: Locomotive engineers can safely resume driving duties following onset of cardiac disease.
