An evaluation of occupational health services within the NHS in London

AIMS: To establish the nature, extent and organization of occupational health service provision for employees within the National Health Service (NHS) in London and to review the systems for monitoring performance. METHODS: Human resources directors and occupational health managers were contacted from a random selection of NHS trusts in the London area and invited to complete an interviewer-led questionnaire. RESULTS: All seventeen trusts interviewed claimed to provide an occupational health service to their employees, with 88% providing this service in-house. The organization of the services varied, although most resided within the human resources function. Only 29% of the trusts could provide a written occupational health policy. Teaching hospital trusts had the most qualified and the highest numbers of medical staff. District/General hospital trusts had the least qualified clinical staff. Although most trusts were able to provide a comprehensive range of services, 87% of occupational health managers felt they could only provide a reactive service. Income was generated from non-NHS sources by 88% of the trusts and all were aware of NHS Plus. There was an indication that some trusts assigned NHS Plus status did not meet the standard of NHS Plus, although the survey took place only 3 months after the launch of NHS Plus. CONCLUSIONS: There was a significant variation in the nature and extent of occupational health services in the NHS trusts. As a consequence, there may be differences in the level of occupational health service available to staff across the NHS in London.     

Provision and perception of occupational health in small and medium-sized enterprises in Sheffield, UK

A random sample of managers of small and medium-sized enterprises (SMEs) was selected from a database of businesses in Sheffield, UK. They were invited to take part in a study to evaluate the provision and perception of occupational health in SMEs in Sheffield. The study used an interviewer-led questionnaire, which collected quantitative and qualitative data; each interview took approximately 40 min to complete. Several approaches to recruitment were adopted during the study. Twenty-eight managers were interviewed over the 6 month study period. All of the SMEs employed <250 people; 43.2% did not have or had never reviewed a written health and safety policy. Only 18% had a written occupational health policy; 14.4% employed the services of a part-time occupational health physician; 7.2% employed a health and safety advisor; and 10.8% employed a part-time occupational health nurse. Twenty-five per cent had a nominated person responsible for occupational health and 67% thought that a doctor or nurse would be the best person to provide an occupational health service. Twenty-eight per cent of the companies carried out some form of pre-employment screening and 14.2% carried out health promotion. Fifteen (53.5%) collected some form of health related absence data. Eight companies (28.6%) organized a formal induction programme for all new employees. Further work should be undertaken in an attempt to improve access to local industry and particularly to SMEs. This study has clearly shown that access is possible, but different strategies of approach were required before a workable strategy could be found. Undoubtedly, this access can be improved by better understanding of the interaction between researchers, occupational health providers and local managers of SMEs.     

The scale of perceived occupational stress

This article reviews previous research on the scale of occupational stress and describes in detail the Bristol Stress and Health at Work study. This study had three main aims: firstly, to determine the scale and severity of occupational stress in a random population sample; secondly, to distinguish the effects of stress at work from those of stress in general life; and finally, to determine whether objective indicators of health status and performance efficiency were related to perceived occupational stress. These aims were investigated by conducting an epidemiological survey of 17,000 randomly selected people from the Bristol electoral register, a follow-up survey 12 months later, and detailed investigation of a cohort from the original sample. The results revealed that approximately 20% of the sample reported that they had very high or extremely high levels of stress at work. This effect was reliable over time, related to potentially stressful working conditions and associated with impaired physical and mental health. The effects of occupational stress could not be attributed to life stress or negative affectivity. The cohort study also suggested that high levels of occupational stress may influence physiology and mental performance. The prevalence rate obtained in this study suggests that 5 million workers in the UK have very high levels of occupational stress.     

Work activity analysis of Finnish occupational health professionals

BACKGROUND: Some Finnish studies have dealt with how occupational health nurses divide their working hours but other occupational health professionals have not been evaluated. AIMS: This study describes how occupational health professionals allocate their working hours between main tasks. METHODS: Questionnaires were sent to 250 occupational health professionals, of whom 176 (70%) returned the completed forms. The data were analysed by using frequencies, means and one-way analysis of variance test. RESULTS: Employee-oriented tasks accounted for roughly 50% of working hours from all occupational health professionals. The remaining working hours were shared between workplace visits, co-operation with partners, other occupational health care responsibilities and tasks in other health care fields, especially in the health care centres. These working hours varied greatly between the different occupational health professional groups. All units employed full-time occupational health nurses, but the services of physicians, physiotherapists and psychologists were usually provided part-time or even restricted to a few hours each week because these services were difficult to obtain. Occupational health nurses working in the municipal health care centres spent more time on workplace visits than other nurses. Employee-oriented tasks were emphasized more in physicians', physiotherapists' and psychologists' work, especially in private medical health care units and in the jointly owned health care units. CONCLUSIONS: The amount of time occupational health professionals are able to spend on workplace activities appears to be determined by the type of their employer.     

Implementation of statutory occupational respiratory health surveillance

Health surveillance is required by UK regulations in certain circumstances, and is usually provided through an occupational health organization. Although there are studies assessing the provision of health surveillance across the country, there are no published studies addressing the practical application of legislation, guidelines and medical research to respiratory health surveillance programmes. An audit of a multidisciplinary health surveillance programme was carried out, using review of occupational health records, occupational hygiene reports and managers' risk assessments, to compare the implementation of health surveillance in different organizations and under different contractual relationships. Sixty-six per cent of National Health Service (NHS) and 56% of industrial workplaces were able to provide risk assessments but were unable to link these with appropriate health surveillance. Twenty-seven per cent of NHS employees potentially exposed to respiratory sensitizers had baseline surveillance, compared with 87% in industry. Fifty-five per cent of Medical Research Council questionnaires were inappropriately administered by the employee themselves, rather than an interviewer as recommended. Other follow-up questionnaires in use had not been formally validated. Non-regular lung function assessment using spirometry was the predominant tool used for follow-up surveillance. There was no overall strategic approach to respiratory health surveillance in the organization studied. Health surveillance programmes should focus on disease prevention without becoming a repetitious application of unvalidated tools. Clinical governance demands quality assurance standards that will effectively implement a coordinated approach to health surveillance.     

The application of the methods of evidence-based practice to occupational health

Evidence-based methods of practice are becoming widely used in many areas of healthcare. The techniques of data appraisal, systematic review and meta-analysis and their application to clinical and preventative medicine through clinical guidelines and economic analyses are well established. These methods have only been applied to occupational health risks and interventions in a very limited way and there is considerable scope for wider use, especially in the clinical aspects of practice. This should improve the quality of prevention and would also enable practitioners to give more soundly based advice and to secure their professional positions as providers of quality assured information. Human and financial resources and commitment to the development of evidence-based approaches by the professions and those they work for are pre-requisites for success.     

Prevention of occupational asthma--practical implications for occupational physicians

BACKGROUND: Occupational factors have been estimated to contribute to approximately 10% of adult-onset asthma and occupational asthma (OA) is one of the most common occupational lung diseases in industrialized areas. Persistent asthma frequently occurs with significant socio-economic impacts. METHODS: A literature search was performed using PubMed. The key term searched was occupational asthma combined with prevention. RESULTS: Primary prevention has been effective for OA related to natural rubber latex, and may have reduced the incidence of diisocyanate-induced asthma. Medical health surveillance has been effective in settings such as the detergent enzyme industry, workers exposed to complex platinum salts and likely for diisocyanate workers in Ontario. Tertiary prevention is still required for workers with OA and can improve prognosis. CONCLUSIONS: OA is potentially preventable. Sufficient studies have demonstrated the rationale and benefit of primary preventive strategies. Medical health surveillance programs combined with occupational hygiene measures and worker education have been associated with improved outcomes but further studies are needed to understand the optimum frequency and measures for such programs and to identify the separate contribution of the components. Until primary and secondary prevention is better understood and implemented, there will also remain a need for tertiary preventive measures.     

Occupational health provision in UK universities

BACKGROUND: Very few studies have been done of occupational health provision across an entire employment sector and universities are particularly understudied. The British government published updated guidance on university occupational health in 2006. AIM: To describe the occupational health services to all the universities in the UK. METHODS: All 117 universities in the UK were included. Detailed surveys were carried out in 2002, 2003 and 2004 requesting self-completed information from each university occupational health service. This paper presents information on general characteristics of the service, staffing, services provided and outcome reporting. RESULTS: There was variation in the type of occupational health provision; half the universities had an in-house occupational health service, 32% used a contractor, 9% relied on the campus primary care or student health service and 9% had ad hoc or no arrangements. In all, 93 of the 117 (79%) universities responded to the detailed questionnaire, the response rate being higher from in-house services and from larger universities. There was a wide variation in staffing levels but the average service was small, staffed by one full-time nurse with one half-day of doctor time per week and a part-time clerical or administrative member of staff. A range of services was provided but, again, there was wide variation between universities. CONCLUSIONS: It is unclear if the occupational health provision to universities is proportional to their needs. The wide variation suggests that some universities may have less adequate services than others.     

Delivery of health surveillance for hand-arm vibration in the West Midlands

BACKGROUND: Concerns about provider competence and quality of hand-arm vibrations (HAVs) health surveillance programmes were identified by Health & Safety Executive (HSE) inspectors. AIMS: To evaluate health surveillance programmes and compare them with published HSE guidance. To identify deficiencies and areas for improvement in the health surveillance programmes. METHODS: A proforma was developed for the study and used on a sample of 10 local occupational health providers. RESULTS: All 10 organizations were aware of current HSE guidance for health surveillance for HAVs but only a minority (30%) were following it. Occupational health provider training, written procedures and health surveillance delivery were all identified as areas requiring improvement. CONCLUSIONS: The majority of organizations were not following HSE guidance. Occupational health providers undertaking health surveillance for HAV require specific training.     

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.     

Occupational health in the European Union

Despite extensive legislation in the European Union, employees remain exposed to occupational risks and there is still a significant burden of work-related ill-health. The trend for more people to work in service industries rather than manufacturing has resulted in a change in the nature of risk and pattern of occupational illness. Worker access to occupational health services ranges from 15 to 96% and depends on the country in which employees live and the type of operation in which they work. The increasing number of small enterprises provides a particular challenge when trying to provide occupational health support to the European Union's 158.4 million workers. European law alone is not sufficient to improve the health of those at work and further action is needed at state, employer and professional level. New initiatives seek to improve the health of the Union's workforce, including a drive for better compliance with new law by every member state. Governments are working with key stakeholders through partnering strategies to develop innovative approaches for better access to quality occupational health services. Furthermore, targets for reduction in occupational ill-health have been identified. Where country laws do not mandate the provision of occupational health services, employers need to see the benefit of providing occupational health support. Finally, the medical profession is making procedures for self-regulation more rigorous and professional bodies are actively engaged in issuing professional standards and guidelines. Ultimately, the individual practitioner is responsible for ensuring that he or she develops and maintains the necessary knowledge and skills to provide competent services.     

Offering physical activity counselling in occupational health care -- does it reach the target group?

BACKGROUND: Employees participating in worksite physical activity (PA) interventions are mostly the physically active and healthy ones. PA counselling may therefore have an important role in reaching 'at-risk' employees. AIMS: To examine (i) how PA counselling offered by occupational health care (OHC) providers reaches the target group of physically inactive employees who have intentions to increase PA and (ii) the relations of 12 selected variables to respondents' willingness to participate in PA counselling. METHODS: Questionnaire survey of employees of client companies of OHC providers. RESULTS: Eight of the 19 OHC providers contacted participated and recruited a total of nine client companies to the study. A questionnaire survey was delivered to all the employees of the companies (n = 1349). Fifty-eight percent of employees (n = 784) responded to the survey and half of them (n = 380) belonged to the target group of being physically inactive and intending to increase PA. Only half of the respondents (n = 201) in the target group were willing to participate in counselling. Respondents in small companies were more interested in counselling than employees in large companies as were white-collar workers compared to blue-collar workers. Earlier PA discussions in OHC and intention to increase leisure-time PA were also positively related to willingness. CONCLUSIONS: A counselling offer attached to a survey did not effectively reach the target group of physically inactive employees who were ready to increase their PA. More individually based approaches such as brief conversations during client contacts are needed in OHC to raise the interest in lifestyle issues.     

A cross-sectional study of employer and employee occupational health needs and priorities within the Irish Civil Service

BACKGROUND: This study aimed to establish how important an occupational health unit (OHU) is to its clients, and to identify the perceived needs and priorities for such a service. METHODS: A cross-sectional postal survey of a stratified, randomly selected group of employees (n = 760) and all human resources (HR) managers (n = 34) was conducted in the Irish Civil Service. Each participant was requested to rate the overall importance of the OHU and to prioritize eight proposed functions for the unit: medical surveillance, general health education, pre-employment/promotion medical assessments, ill-health retirement assessments, return-to-work (after sick leave) assessments, occupational health education, research, and general medical screening. The results were analysed according to age group, gender, grade and occupation. RESULTS: There was a response rate of 69% from employees and 74% from personnel managers. Significantly more HR managers than employees (92 versus 81%) thought an occupational health service was either important or very important. There were also differences in prioritization of functions by employees and HR managers. HR managers prioritized those functions concerned with assessing individuals' fitness for work, notably pre-employment/promotional health assessments, whereas employees consider group-directed 'preventative' functions to be more important, i.e. general medical screening, health education and medical surveillance. Both sets of opinions are not mutually exclusive, and considerable overlap exists, notably in the areas of occupational and general health education.     

Occupational toxicology and the control of exposure to pharmaceutical agents at work

BACKGROUND: The pharmaceutical industry employs >350 000 people worldwide in operations including research and development (R&D), manufacturing, sales and marketing. Workers employed in R&D and manufacturing sectors are potentially exposed to drug substances in the workplace that are designed to modify physiology and also to chemical precursors that are potentially hazardous to health. Pharmaceutical workers are at risk from adverse health effects, including occupational asthma, pharmacological effects, adverse reproductive outcomes and dermatitis. AIM: This study aimed to describe the approaches taken by pharmaceutical companies for identifying and communicating potential adverse health effects that may result from workplace exposures and in setting 'in-house' exposure control limits and to highlight the challenges in controlling workplace exposures to increasingly potent compounds. METHOD: The literature was reviewed by searching the Medline and HSELine databases. RESULTS: The findings are presented in five sections, covering: test methods and approaches to occupational toxicology; hazard communication; approaches to setting health-based occupational exposure limits for pharmaceutically active agents; recent approaches to risk control; and occupational hygiene and exposure controls. CONCLUSION: Significant efforts have been directed at predicting and evaluating potential occupational health hazards in the pharmaceutical industry. The pharmaceutical industry has provided leadership in controlling exposure to hazardous substances. Much of this work has been driven by a real need to control occupational exposures to substances that can have profound adverse health effects in exposed employees and that are becoming increasingly more potent.     

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.     

Occupational health services in the UK--challenges and opportunities

BACKGROUND: A small minority of the UK workforce currently has access to an occupational physician. Reduction in the size of enterprises, the emergence of atypical work patterns and problems recruiting and training occupational health specialists risk making this minority even smaller. AIM: This paper considers the challenges currently facing occupational medicine and how we can improve access to occupational health services (OHS). It aims to highlight some of the diverse internal and external factors that restrict the UK's ability to provide all workers access to OHS. METHOD: A literature review was carried out and combined with awareness of current trends in business and new legislation together with provision of occupational medicine in other countries. RESULTS: Potentially controversial solutions that might help to make OHS more widely accessible were identified and are discussed. It is hoped that these will provoke further debate. CONCLUSION: Individually and organizationally, we must examine and improve capabilities if we are to improve worker access to OHS and deliver targets to reduce occupational ill-health. It is suggested that this requires a strategic shift to apply resources differently. There is need to explore delegation of tasks traditionally performed by doctors to nurses and other staff together with the outsourcing of non-core work. The increased use of telemedicine and the enhanced use of information technology for training, risk assessments, wellness programmes and questionnaire-based health assessments are other developments that should be explored.     

Low prevalence of clinical latex allergy in UK health care workers: a cross-sectional study.

The prevalence of natural rubber latex allergy amongst health care workers has been reported to vary between 1 and 40%. This is because different diagnostic criteria have been used on heterogeneous groups of subjects. We have undertaken a cross-sectional study of all 5600 employees in two National Health Service trusts served by one department of occupational health and one department of clinical immunology. The period prevalence (1999-2000) for Type I clinical latex allergy in the clinical health care workers was found to be 17/3500 (0.5%). Difficulties in diagnosis and factors which may have contributed to this low prevalence rate are discussed. No cases were forced to leave health care work as a consequence of their allergy.     

Benchmarking self-reported practice regarding Scottish Executive guidance on hepatitis C-infected health care workers

BACKGROUND: The 2002 Scottish Executive guidance 'hepatitis C-infected health care workers' advised NHS Scotland occupational health departments regarding screening health care workers (HCW) who perform or who may perform exposure-prone procedures (EPPs) for hepatitis C virus (HCV) infection. In 2004, 2 years following the launch of the guidance, there was anecdotal evidence of challenges to implementation and clinical and ethical concerns regarding the screening process. AIM: To benchmark the implementation of the Executive guidance on hepatitis C-infected HCW in NHS Scotland. METHODS: Lead occupational health practitioners in 15 Scottish NHS Boards completed a questionnaire and provided relevant local policies. RESULTS: All 15 NHS Boards responded: 87% (n = 13) had implemented the guidance with partial implementation in the remaining boards. While 87% required identified and validated samples (IVS), no consistent method was reported for how results from an IVS were recorded. There was also no consensus as to the duration a result was considered valid or consistency in charging for tests required by other employers. Across Scotland, some employee groups were being screened over and above those recommended within the guidance. Overall, there was agreement on the value of a standardized NHS hepatitis C status certificate and the importance of explicit screening criteria and identifying EPP workers. CONCLUSION: The survey confirms the challenges in implementing the guidance on managing HCV-infected HCW within NHS Scotland. These include lack of clarity regarding who, when and how frequently a HCW should be screened and how the results of such tests should be recorded.     

Report of a system for diagnosis, categorizing and recording occupational mental ill-health

BACKGROUND: UK statutory systems for occupational disease recording do not include mental illness resulting from occupational stress. The issue is included within physician reporting systems, but there is no agreed set of criteria for diagnosis of occupational causation and no agreed system of categorization in terms of type of causation by workplace factors. METHOD: A multidisciplinary group of occupational health professionals, in conjunction with human resources staff, developed a system for the diagnosis, categorization and recording of occupational mental ill-health. RESULTS: The developed system was applied as a pilot and the outcome from its first year of use is presented. CONCLUSIONS: The system is considered to have operated well in pilot, and has now been adopted as a standard operating procedure by the occupational health provider who developed it. The system is proposed as a tool in the development of standardized NHS or UK national systems for the recording of occupational mental ill-health.     

Compliance with follow-up after occupational exposure to hepatitis C

BACKGROUND: Accidental percutaneous exposure to blood containing hepatitis C virus (HCV) is reported by health care workers more frequently than exposure to human immunodeficiency and hepatitis B virus. The transmission rate following such an exposure is approximately 1.9%. Little is known about the attendance rate of such staff for follow-up testing following exposure to HCV. AIM: To determine whether our follow-up programme for staff exposed to hepatitis C would allow the early detection and treatment of infected staff members. METHOD: We reviewed all staff exposures to hepatitis C reported to the occupational health department of a London teaching hospital over a 8-year period. RESULTS: Of 105 exposures, 21% of staff attended for early (6 or 12 weeks) and late (26 weeks) post-exposure follow-up. Thirty-seven per cent attended early follow-up only and 1% attended late having not attended early follow-up. Forty per cent did not attend any follow-up appointments with us. CONCLUSION: With the availability of effective treatment for early HCV infection, it is vital that occupational health departments encourage staff to attend at least for early follow-up. Access to HCV-RNA testing at this early stage should allow detection and early treatment of the small proportion who seroconvert.
