Occupational mental health: a brief history

This paper describes the development of occupational mental health in the United Kingdom. It looks at the increasing involvement of occupational health staff in this aspect of the workplace and the role played by organizational psychologists in exploring the relationship between work and mental well-being. It provides a background for the reviews of current knowledge described in the other papers in this issue of Occupational Medicine.     

Occupational health in the Andalusian Fisheries Sector

BACKGROUND: The conditions of work in the fisheries sector are arduous with high rates of occupational accidents. Numerous factors are known that can directly influence the health of the sailor or fisherman both in fishing and merchant fleets. AIM: To evaluate the health status, safety and working conditions in the Andalusian fishing sector. METHODS: Cross-sectional questionnaire study with proportional sampling of the health and lifestyles of fishery workers in 19 of the 23 Andalusian ports. RESULTS: A total of 247 workers employed on 202 craft fishing boats responded. In all 87% of workers reported a current medical condition. The main problems reported were musculoskeletal disorders, respiratory diseases, diseases of the digestive system, eye problems and skin problems. A total of 72% reported taking some self-prescribed medication, and 60% of fishery workers smoked. Nine per cent of fishery workers admitted taking illicit drugs and 3% reported using illicit drugs on board. Diets on board were poorly balanced. While on board, 62% of crews reported a subjective significant worsening of previous health. The lifetime prevalence of accidents was 76%. CONCLUSIONS: Fishery workers had a high prevalence of self-reported medical problems, a high prevalence of self-medication, poor diets and frequently smoked. Self-medication and some medical conditions (diabetes, angina and depression) may reflect a potential failing of health checks and pre-employment checks. National health services and insurance companies dealing with occupational health should focus more on appropriate health checks, illness prevention and health promotion activities for this population.     

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.     

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.     

Occupational health in general practice in an industrial area of Singapore

The aim of this study was to estimate the caseload with regard to the proportion of work-related medical cases in factory workers and to survey knowledge of and attitudes to occupational medicine among doctors in an industrial area in Singapore. To this end, a self-administered questionnaire was given to 74 general practitioners in the industrial district of Jurong in Singapore. Overall, there was an 89.2% response rate. Thirty-three of the 66 respondents were males. Mean age was 40.8 years (range 27-64 years). Twenty-four (36%) had some postgraduate training in occupational medicine (GP-OM) while the rest did not (GP). The caseload for all doctors was similar with regard to the number of adult patients and, more specifically, the number of factory workers seen per day. The majority of doctors (76.6%) felt that <10% of factory workers seen had work-related problems. Most (70%) felt confident in dealing with the occupational problems that arose. However, a large percentage (78% of GPs, 45.8% of GP-OMs) felt that training in occupational medicine was inadequate. This is reflected in the knowledge questions, where GPs did not score as well as GP-OMs. It was concluded that GPs working in this industrial area see a good proportion of factory workers, in a fair number of cases for work-related problems. However, only a third of the GPs are qualified in occupational medicine. These factors highlight the need for more emphasis on occupational medicine training among general practitioners, especially those working in industrial areas.     

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.     

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.     

Occupational epidemiology

The epidemiological literature for assessing risk in many, if not most, modern occupations has now become sufficiently obsolete that it can no longer be depended upon to guide either prevention or adjudication of compensation. This obsolescence must be dealt with by developing new sources of information pertinent to occupational hazards and the risks associated with most occupations. Ideally, a comprehensive surveillance mechanism that would be automatically updated for the changing risk in a changing economy would be ideal and may be attainable with further developments in health information technology. The characteristics of such a system are described. However, there are many obstacles to such a system which appear insurmountable in the short term. A more eclectic plan for cooperation and data-sharing would help in the short term and would establish a pattern of collaboration that could both place adjudication on a more solid foundation and avoid allegations of collusion in business. The general outline for a practical programme of collaboration along these lines is presented.     

Occupational hygiene science and its application in occupational health policy, at home and abroad.

This paper examines the role of occupational hygiene in the overall framework of occupational health. It draws attention to the unique combination of required individual science subjects, and to the way in which occupational hygiene science contributes to the practice of occupational hygiene in the real world. It focuses in particular on occupational exposure standards. The paper provides, as an example, the specific case of occupational aerosol exposures. It is here that scientific research has made a notable impact on standards and led to a considerable degree of international harmonization. Finally, some broader insights into occupational exposure standards are given, based on experience gained during visits to a number of contrasting countries. The similarities and differences between the various national approaches help indicate what is generic in how standards are set. Such insights provide a basis for further international harmonization in the future. It is concluded that occupational exposure standards appear to be most effectively applied in countries where there are strong occupational hygiene cultures.     

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.     

Occupational health nursing education for the 21st century

Occupational health nurses are the largest group of occupational health professionals, and are critical to the delivery of quality health care services to the nation's work force. Educational preparation of occupational health nurses has advanced in recent years, and the need for occupational health nurses with advanced degrees is expected to increase. Occupational health nurses use licensure, continuing education, certification, supervisor and peer assessment of job performance, formal education, and practice to maintain their professional competence and protect the public's health. New strategies must be developed to prepare nurses to promote a safe and healthful work force. Funding for programs to prepare occupational health nurses will be essential for meeting this demand. Continuing education programs for occupational health nurses must be developed that demonstrate effectiveness in developing occupational health nurses' skills while minimizing their time away from the workplace.     

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.     

Perception and provision of occupational health services in the UK

BACKGROUND: There is difficulty in defining occupational health services among stakeholders of the service. Concurrently, there are concerns about the state of occupational health provision in the UK. AIMS: To determine stakeholders' perception of the services that occupational health encompasses and the level as well as the rationale behind the provision of these services. METHODS: The research was undertaken as a postal questionnaire survey of the FTSE 350 companies and selected public sector organizations in the UK. This was followed up by telephone calls to a random selection of non-respondents to obtain non-respondent data. RESULTS: There is a difference in opinion among managers and occupational health professionals about the services provided by occupational health. Taking into account non-respondent data to partially adjust for overestimation biases, the level of provision of occupational health services among the FTSE 350 companies is 69% and in public sector organizations is 95%, giving an average provision of 72%. Sixteen per cent of respondents thought there was a trend towards outsourcing of services. The most frequently cited reason for provision of an occupational health service was that it was for the benefit of employees. CONCLUSIONS: There remains room for improvement in the level of occupational health services provision in large UK private sector organizations. By bridging the gap between the different stakeholders' perceptions of the remit and benefits of the service, a higher level of provision in the private sector similar to that of public sector organizations can be achieved.     

Adherence to mental health guidelines by Dutch occupational physicians

BACKGROUND: In 2000, the Dutch Association of Occupational Physicians published a national guideline for the management of employees with mental health problems. OBJECTIVES: To examine predictors of adherence to this guideline by Dutch occupational physicians (OPs). METHODS: Using the Theory of Planned Behaviour, a questionnaire was developed about self-reported guideline adherence of OPs and possible predictors of this behaviour. A total of 165 OPs were approached to complete the questionnaire and registration forms of first consultations of workers with mental health problems. Performance indicators based on the guideline were developed to calculate performance rates of guideline adherence by OPs. RESULTS: Eighty of 165 (48%) OPs approached completed the questionnaire. Fifty-six OPs returned one or more registration forms, totalling 344 consultations. On a five-point Likert scale, ranging from never (1) to always (5), the mean score on self-reported guideline adherence was 2.35, compared to a mean score of 4.06 on the intention to comply with the guideline. The mean performance rate of OPs ranging from 0 to 2 was 1.27 on diagnosis and 0.60 on guidance. No relation was found between self-reported guideline adherence and performance rates. Self-reported guideline adherence correlated significantly with perceived behaviour control (r = 0.48, P < 0.05), subjective norms (r = 0.33, P < 0.05) and positive job stress (r = 0.35, P < 0.05). CONCLUSIONS: Guideline adherence by Dutch OPs lags behind its acceptance. Further implementation efforts need to focus on diminishing barriers and enhancing social norms of OPs to work according to the guideline.     

Methods to persuade higher management to invest in health promotion programmes in the workplace

This study was conducted to find effective methods to persuadehigher management to invest in workplace health promotion (WHP)programmes. The study included 639 occupational health professionalsselected from the directory of the Japan Society for OccupationalHealth. A questionnaire survey was mailed to health professionalsthroughout Japan in 1992, and all respondents were asked toidentify themselves. We received 242 replies, which constituteda response rate of 38%. Eighty-one per cent of the respondentshad attempted to persuade higher management to implement a WHPprogramme. Health professionals frequently presented their caseto higher management through a safety and health committee (SHC),and advice provided at the SHC was perceived to be the mosteffective method by occupational nurses (ONs) and safety andhealth supervisors (SHSs). This method was rated second by occupationalphysicians (OPs), who thought recommendations from OPs stipulatedby the Industrial Safety and Health Law to be most effective.Statistics on medical examinations constituted the data mostfrequently used to persuade higher management, followed by reportson worksite inspections and health care plans. Nearly 90% ofOPs and 80% of ONs and SHSs felt that the above methods werefairly successful.     

Occupational and social variation in subjective health complaints

OBJECTIVES: Occupational and social factors are thought to be important determinants of health inequality. The aim of this study was to examine the relationships between occupation, lifestyle and subjective health complaints (SHC). METHODS: SHC and self-reported sickness absence were recorded in a cross-sectional study of 662 individuals aged between 16 and 67 from five occupational groups: blue-collar, school/education, health service, white-collar and service. Differences in SHC and sickness absence were investigated. A model of sociodemographic, lifestyle and work-related factors was tested to examine associations with SHC. RESULTS: Few differences in SHC and sickness absence were found when educational level, age and gender were controlled for. Female health service workers did, however, show significantly higher prevalence of pseudoneurological complaints compared with white-collar workers. Male blue-collar workers had significantly higher frequency of sickness absence than white-collar workers; otherwise, there were no significant differences in frequency and duration of sickness absence. The model explained very little of the variance of SHC (R(2)(adj) = 0.15) and occupational group was not significantly associated with health. Physical workload and sleep quality showed significant relationships with SHC for both genders. Education, however, was a significant factor for women only. CONCLUSIONS: The differences in health found between major occupational groups in this sample were mainly explained by gender differences. Sociodemographic, lifestyle and work-related factors explained little of the variance in SHC, suggesting that factors such as psychological demands, perceived job stress, coping and other psychological factors might be of stronger importance for SHC.     

Medical education in China for the 21st century

Drastic changes are occurring in medical education around the world. Medicine and medical technologies are developing rapidly and expanding beyond the multidisciplinary area. The needs of medical care and medical education are different even from those of several years ago. In order to cope with these increasing social needs, the innovation of medical education in China has become an urgent and important problem. This study is an attempt to answer the question of how to develop medical education in China for the 21st century, based on a historical review of the development of medical education. This development might be divided into three periods: (1) before the Cultural Revolution; (2) the Cultural Revolution (1966-76); and (3) post-Cultural Revolution (1977-present) in modern China, and based on problem analysis of the curriculum, teaching methods, education evaluation, systems and policies and the balance between educational needs and supplies. We concentrate on the discussion of how to solve these problems, and have designed a new strategy for the further development of medical education in China. This discussion and newly developing strategy focuses on the main targets and priorities and adoption of suitable measures according to the conditions of the country. The purposes are to elevate the quality of medical education, to train qualified doctors to meet continuously increasing needs and to maintain the development of medical education for the 21st century in China.
