The management of occupational health by NHS Trusts in the north of England

This paper reports the findings of an audit of the management of occupational health arrangements in 36 NHS Trusts in the Northern and Yorkshire region of England. A questionnaire was designed based on a national NHS occupational health standard to obtain data on eight categories of occupational health activity: health and safety; pre-employment assessments; Infection Control; health surveillance; sickness absence; ill-health retirement; health promotion and record storage. The management arrangements for occupational health were varied. Assessments of workplace hazards, prevention of HIV-positive workers from performing exposure-prone invasive procedures and the assessment of pregnant workers were identified as issues for further consideration. Provision of competent and effective occupational health services will assist in the management of sickness absence and in the protection and promotion of health of staff. It will also contribute to the health and safety of patients.     

Exposures to blood and body fluids in Brazilian primary health care

Background Primary health care workers (HCWs) represent a growingoccupational group worldwide. They are at risk of infectionwith blood-borne pathogens because of occupational exposuresto blood and body fluids (BBF). Aim To investigate BBF exposure and its associated factors amongprimary HCWs. Methods Cross-sectional study among workers from municipal primaryhealth care centres in Florianópolis, Southern Brazil.Workers who belonged to occupational categories that involvedBBF exposures during the preceding 12 months were interviewedand included in the data analysis. Results A total of 1077 workers participated. The mean incidencerate of occupational BBF exposures was 11.9 per 100 full-timeequivalent worker-years (95% confidence interval: 8.4–15.3).The cumulative prevalence was 7% during the 12 months precedingthe interview. University-level education, employment as a nurseassistant, dental assistant or dentist, higher workload score,inadequate working conditions, having sustained a previous occupationalaccident and current smoking were associated with BBF exposures(P 0.05). Conclusions Primary Health Care Centres are working environmentsin which workers are at risk of BBF exposures. Exposure surveillancesystems should be created to monitor their occurrence and toguide the implementation of preventive strategies.     

The impact of Hymenoptera venom allergy on occupational activities

The objective of this study was to investigate the impact ofallergy to hymenoptera venom on the occupational activitiesof patients undergoing immunologic treatment for insect stinganaphylaxis. The design was a cross-sectional study conductedin a sample of 500 out of 1,500 patients undergoing venom inmunotherapyfor insect sting reaction in 13 allergy clinics in Israel. Aself-administered questionnaire was used to collect data aboutdemographic characteristics of patients, severity of the allergicreaction, and adverse effects on occupational activities. Ofthe 204 respondents who were part of the labour force, 48.5%reported adverse effects on routine occupational activities.The factors with a significant influence on the probabilityof adverse occupational effects were: (1) patient's type ofwork (blue collar vs. white collar: OR=;3.22, p<0.001; armyvs. white collar: OR=5.28, p=0.001); (2) severity of the allergicreaction (severe reaction vs. mild/moderate reaction: OR=2.34,p=0.007). Our findings suggest that severe insect sting allergyhas an adverse impact on patients' occupational activities.This factor requires special attention by the medical community.Social workers and occupational physicians should collaboratein the assessment and management of these patients.     

The impact of the COSHH regulations on workers with occupational asthma

In the UK, the COSHH Regulations give specific guidance thatemployers have duties to inform, instruct and train their employeesabout occupational risks and provide them with suitable healthsurveillance. The aim of the study was to evaluate the impactof the Regulations on employees with occupational asthma. Onehundred consecutive patients attending an occupational lungdisease clinic completed a questionnaire assessing the implementationof the COSHH Regulations in their workplace. Twenty-eight percent had a pre-employment inquiry about asthma, 31% had regularhealth surveillance by questionnaires and 19% had regular lungfunction assessment at work. Pre-employment spirometry was carriedout in 44% of the workers who were exposed to one of the originalseven prescribed agents, significantly more than those who wereexposed to other agents (19%) (p < 0.05). Moreover, figuresfor spirometry during employment were 31% and 8% respectively(p < 0.05). The patients who worked after ‘COSHH’but before ‘MS25’ had a tendency to be providedwith health surveillance more than those who worked after both‘COSHH’ and ‘MS25’. Ninety-one per centof the patients had never been informed about the risks of gettingasthma at work and 73% had never seen the safety data sheets.The workers who (1) worked after ‘COSHH’ introduction;(2) worked in larger firms and (3) were exposed to one of theoriginal seven prescribed agents, had a tendency to be informed,instructed and trained more than the rest. However, there wereonly significant statistical differences (p<0.05) in termsof the safety data sheet provision between the cases who workedbefore the time of the legislation and those employed afterwards.     

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.     

A Study of the Impact of Occupational and Domestic Factors on Insomnia among Industrial Workers of a Manufacturing Company in Japan

Insomnia is one of the most common health problems and has recentlybeen re-termed ‘Disorders of Initiating and MaintainingSleep’, or DIMS. The main purpose of the present studywas to investigate the relationship between daily psychosocialstressors, to which workers are exposed in occupational and/orprivate life, and insomnia among male industrial workers ina medium-sized company located in Nagasaki City, Japan. Allof the workers in the company (n=368, male=319) were asked toanswer six sleep related questions and 24 questions about workingand private conditions. Two hundred and seventy-one (85.0%)of them completed the questionnaire (average age was 40.9 yearsold). Twenty seven point seven per cent of the subjects complainedof insomnia in the last month prior to the survey and the prevalencewas in general accord with previous surveys. On the other hand,the proportion of hypnotic use (1.1%), especially in insomniacgroup (2.7%) was lower than previous reports. The results ofmultiple logis regression analysis demonstrated that four psychosocialfactors were significantly associated with insomnia: i.e. VDTwork overload (odds ratio [OR] 5.058; 95% confidence intervals[95% Cl] 2.381–10.745), limited space of bedroom (OR 2.612;95% Cl 1.283–5.683), over-involvement in job (OR 2.78;95% Cl 1.188–6.540), frequent alcohol beverages consumption(OR 2.595; 95% Cl 1.177–5.719).     

Occupational dental erosion from exposure to acids: a review

Objective Dental erosion is characterized as a disorder witha multifactorial aetiology including environmental acid exposure.The purpose of this article was to summarize and discuss theavailable information concerning occupational dental erosion. Methods Information from original scientific papers, case reportsand reviews with additional case reports listed in PubMed, Medlineor EMBASE [search term: (dental OR enamel OR dentin) AND (erosionOR tooth wear) AND (occupational OR worker)] were included inthe review. References from the identified publications weremanually searched to identify additional relevant articles. Results The systematic search resulted in 59 papers, of which42 were suitable for the present review. Seventeen papers demonstratedevidence that battery, galvanizing and associated workers exposedto sulphuric or hydrochloric acid were at higher risk of dentalerosion. For other industrial workers, wine tasters and competitiveswimmers, only a few clinical studies exist and these do notallow the drawing of definitive conclusions. Conclusion Occupational acid exposure might increase the riskof dental erosion. Evidence for occupational dental erosionis limited to battery and galvanizing workers, while data forother occupational groups need to be confirmed by further studies.     

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.     

Hempson Industries UK Ltd. A case study in occupational health services--the solution

In the February 1996 issue of Occupational Medicine, we publisheda case study in which the Chief Medical Officer of Hempson Industries,Steve Saunders, had just returned from a European conferencewhere he delivered a well-received keynote presentation on work-relatedstress disorders. He was delighted with this success and hismore general success in establishing a professional and proactiveoccupational health service during his two years with HempsonIndustries. His delight, however, was undermined by his receiptof an internal memorandum from the newly appointed Directorof Finance and Administration, Richard Coleman. The letter citedBoard colleagues' criticisms of the contribution of OHS to companyresults, the expense of some services like health screeningand recruitment medicals and the seemingly slow and unresponsivebehaviour of most OHS staff. It also proposed the out-sourcingof occupational health to Boone Occupational Health Care Inc.,an American private occupational health service. We invitedreaders to reply to the case study, explaining what they woulddo in Steve's situation. Out of a number of replies, four wereselected for publication and follow. The author of the casestudy, Greg Shaffer, then provides some final comments.     

Occupational health guidelines for the management of low back pain at work: evidence review

There is increasing demand for evidence-based health care. Back pain is one of the most common and difficult occupational health problems, but there has been no readily available evidence base or guidance on management. There are well-established clinical guidelines for the management of low back pain, but these provide limited guidance on the occupational aspects. Occupational Health Guidelines for the Management of Low Back Pain at Work were launched by the Faculty of Occupational Medicine in March 2000. These are the first national occupational health guidelines in the UK and, as far as we are aware, the first truly evidence-linked occupational health guidelines for back pain in the world. They were based on an extensive, systematic review of the scientific literature predominantly from occupational settings or concerning occupational outcomes. The full evidence review is on the Faculty web site (www.facoccmed.ac.uk), but an abridged version is presented here to aid its dissemination.     

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.     

Acute respiratory symptoms among sisal workers in Tanzania

Background Few studies have focused on respiratory health effectsamong sisal workers. Aim To report on the prevalence of acute respiratory symptomsamong sisal processors. Methods We interviewed 163 dust-exposed brushing and decorticationworkers and 31 low-exposed security workers from six sisal estatesin Tanzania using a modified symptom score questionnaire todetermine the prevalence of acute respiratory symptoms duringwork. Groups were compared using chi-square tests, Fisher'sexact tests, t-tests and logistic regression, adjusting forconfounding factors. Results After the first working day of the week, 73% of thebrushing workers reported dry cough, 66% sneezing, 65% productivecough, 63% running nose and 34% stuffy nose. Brushing workershad a significantly higher prevalence of these symptoms thandecortication workers. Brushing and decortication workers hadsignificantly more dry cough and sneezing than the control groupof security workers, when adjusting for age, smoking, past respiratorydiseases and residence. Conclusion Processors of sisal fibre have a high prevalenceof acute respiratory symptoms. More detailed studies on workand health in sisal estates are needed, including exposure studies.     

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.     

Exploring the need for an occupational health service for those working in primary care

A research nurse interviewed 55 practice staff in 11 generalpractices to ascertain their views about their needs for occupationalhealth care. In a second parallel study, a specialist in occupationalmedicine undertook an in-depth audit of occupational healthprovision in five other general practices with respect to theorganization, the health and safety process, the services andthe working environment. In the first study, the majority ofpractice staff reported the need for various aspects of occupationalhealth care, particularly stress at work. In the second study,general practitioners and practice managers possessed a basicawareness of occupational health matters such as Health andSafety legislation, but their limited knowledge was not translatedinto effective management. General practice staff did not knowwhere to obtain occupational health advice; most practices hadno policies or procedures in place to manage health and safety.Both studies illustrate the need for expert occupational healthadvice in primary care.     

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.     

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.     

Smoking and Exposure to Occupational Hazards in 8,304 Workers in Guangzhou, China

This cross-sectional study aimed to describe the pattern ofsmoking in relation to occupational hazard exposure in a workingpopulation in Guangzhou, China. In 1994, data on smoking andoccupational hazard exposure from occupational health recordsof 8,304 subjects aged 35 years or older from 47 randomly selectedfactories were studied. About 49% of the men and 55% of thewomen were exposed to dust, chemicals or other hazards. Theprevalence of smoking was 56.1% in men and in women. The prevalenceof smoking in men was higher in those who were younger, withprimary education or who were workers. In women, those who wereolder, with primary education or in management jobs had highersmoking prevalence. In men and women, subjects who were exposedto occupational hazards had higher smoking prevalence: the highest(71.6%) was found in male workers exposed to dust. Urgent tobaccocontrol measures are needed to prevent the epidemic of smoking-relatedand occupation-related diseases in the workplace in China.     

Factors influencing uptake of influenza vaccination among hospital-based health care workers

BACKGROUND: Vaccination of health care workers against influenza has been shown to lower mortality among elderly patients, but uptake of voluntary vaccination among health care workers remains low. AIMS: Factors influencing uptake of vaccination were examined among a cross-section of health care workers based in an NHS Trust. METHODS: A structured, self-administered questionnaire was mailed to a random sample of health care workers based in the acute services sector of a UK National Health Service Trust, 6 months following a voluntary immunization programme implemented as part of the Scottish Executive Health Department winter planning arrangements for 2000-2001. The programme was promoted using posters in clinical areas and a single leaflet given to all staff through a paycheck advice note. RESULTS: Five hundred and fifty-one health care workers (53%) responded to the questionnaire and influenza vaccination was accepted by 150 (28%). The occupational health poster strongly influenced the decision to accept vaccination [odds ratio (OR) = 11.01; 95% confidence interval (CI) = 2.13-56.80; P < 0.0001]. Other significant influences included female sex (OR = 9.11; 95% CI = 1.26-65.72) and perceived risk of contracting flu without the vaccine (OR = 7.70; 95% CI = 1.44-41.05). Misconceptions regarding the purpose of the vaccination campaign were common and concern regarding possible side-effects was a deterring factor for vaccination uptake. CONCLUSION: Our study showed that visual material displayed throughout the workplace strongly influenced the acceptance of influenza vaccination. Future campaigns should also emphasize the positive benefits to patients of health care worker immunization, with readily accessible information regarding side-effects available from all sources.     

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.     

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.
