Evaluation of an occupational health service for general practitioners and their staff in a primary care trust

BACKGROUND: An occupational health service was set up in 2002 for general practitioners (GPs) and their staff in a London primary care trust (PCT). The service was based on a needs assessment undertaken in the locality in 1998. AIMS: To evaluate awareness, usage and perceived helpfulness of the service amongst GPs and practice managers, and to ascertain current perceived priorities for what to include in the service. METHODS: Questionnaire survey sent postally and electronically to 199 named GPs and 69 practice managers in 78 practices in the PCT. RESULTS: Overall 119/268 (44%) responses were received from 54/78 practices (69%). Awareness of the existence of the service was high (76%), and although uptake had been poor, this was not related to a perception that the service was unlikely to be helpful. Almost all those who had used the service had found it helpful. Nineteen (16%) respondents asked for more information about the service. Advice on health and safety law and fitness for work assessments were the highest priorities and hepatitis B immunization lowest, as in the 1998 needs assessment. However, a discrepancy between GPs and practice managers with regard to the perceived relative importance of pre-employment health screening and counselling/stress management emerged. CONCLUSIONS: The service is valued by users but could be developed by exploring new ways to disseminate information about the service and deliver it.     

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

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

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.     

Management of hepatitis B immunizations and blood exposure incidents in primary care

AIM: To investigate how well primary care health care workers, with no access to an occupational health service (OHS), have managed their hepatitis B immunizations and blood exposure incidents, compared with National Health Service Trust staff, with access to an OHS. METHOD: A questionnaire was sent to 78 general practitioners (GPs), 93 general practice nurses, 81 NHS Trust consultants and 88 NHS Trust community nurses, in the Airedale area of West Yorkshire in June 2001. RESULTS: The response rate was 80%. GPs were significantly less likely than consultants to have received a hepatitis B booster vaccination after their primary course (57 versus 80%, P < 0.009) and significantly less likely to have had their blood anti-HBs test checked after their last vaccination (74 versus 94%, P < 0.011). General practice nurses were significantly less likely to fill in a blood exposure incident form after an injury than community nurses (56 versus 91%, P < 0.006). Overall, the group with access to an OHS was significantly more likely to have received a hepatitis B booster (P < 0.036), have had a blood anti-HBs test after last vaccination (P < 0.010) and to have filled in a blood exposure incident form after last blood exposure (P < 0.033), than the group without access to an OHS. CONCLUSION: Any future OHS with responsibility for primary care, should consider calling in all GPs and general practice nurses for a review of their hepatitis immunity and for education regarding the management of blood exposure incidents.     

The involvement of occupational health services prior to ill-health retirement in NHS staff in Scotland and predictors of re-employment

OBJECTIVE: To assess the process, causes and outcomes of retirement because of ill-health in NHS staff in Scotland. Particular areas to be investigated include the involvement of occupational health services, access to rehabilitation and redeployment, current health, whether working again and to identify predictors of re-employment. METHOD: An ill-health retirement (IHR) questionnaire was mailed to 863 NHS staff awarded IHR benefits by the Scottish Public Pensions Agency between April 1998 and March 2000. RESULTS: In all, 49% of the 863 postal questionnaires were returned. The most common reasons for retiring were diseases of the musculoskeletal system (38%) and mental disorders (21%). Seventy-one percent of the participants reported their ill-health was partly or completely work related and 29% not work related. Ninety-two percent of NHS staff had attended an occupational health department prior to IHR. Twenty-three percent of participants had no contact with their line manager during their illness prior to retiral. Eighteen percent of individuals were offered the opportunity of working part-time and 15% offered alternative work. Seventeen percent of participants have obtained other work. Predictors of re-employment after IHR were: medical condition, managerial responsibility, improvement of health, wanting to work again, occupation and age at retirement. CONCLUSION: This is the first comprehensive study investigating NHS staff experiences of IHR in Scotland. This study illustrates the need for improved support and rehabilitation for ill-health care workers and that there is the potential to reduce levels of ill-health retirement.     

An assessment of occupational health care in the Netherlands (1996-2005)

BACKGROUND: The extensive Dutch occupational health care system of the past decade has not led to the desired outcomes, namely, a decrease of work absenteeism and the associated costs. AIM: To assess the differences between in-house and external occupational health care services in the process quality of occupational health care provided. METHODS: In total, 26 interviews were conducted with chief executive officers of occupational health services (OHS). The responses and other relevant policy documents were analysed and described. A key component of this process was to compare differences between in-house and external services. RESULTS: Notable differences in quality were found to exist between in-house and external occupational health care systems, with the in-house occupational health care services offering the highest process quality. CONCLUSION: Our findings suggest that the effectiveness of OHS is mainly dependent on their structure (in-house versus external) and on economic factors (profit driven versus not for profit).     

Evidence-based care for low back pain in workers eligible for compensation

BACKGROUND: Although guidelines for the management of low back pain have been promoted, few studies have assessed their effectiveness. One previous study did not include patients with workers' compensation claims. AIM: To assess the efficacy of evidence-based care for acute low back pain in patients eligible for workers' compensation. METHODS: In a prospective audit, workers in a health service who presented with acute low back pain were offered the option of usual care from their general practitioner or care provided by a staff specialist who practiced according to evidence-based guidelines. Outcomes were measured in terms of return to normal duties, time off work, recurrence of pain or persistence of pain. RESULTS: Evidence-based care was accepted by 65% of injured workers. Compared with those who elected usual care, these workers had less time off work, spent less time on modified duties and had fewer recurrences. A significantly greater proportion (70%) resumed normal duties immediately, and fewer developed chronic pain, than those managed under usual care. Three types of patients were identified: those who complied readily with evidence-based care, those who initially expressed firm beliefs about how they should be managed and those with occupational psychosocial factors. CONCLUSIONS: Evidence-based care can be successful in retaining patients at work, reducing time off work or on modified duties and reducing recurrences and chronicity. The gains are achieved by conscientiously talking to the patients, and not by any particular or special passive interventions.     

Occupational Health Services in Manufacturing Industries in Nigeria

The provision of adequate health care facilities to cater forthe health of workers is an important consideration in the managementof manufacturing industries, since productivity is dependenton the health status of the workers. There are very few studiesevaluating the health care provision in Nigerian industries.This study elucidates such health care services in Edo and DeltaStates of Nigeria. One hundred and thirty-five (56%) of the241 registered manufacturing industries in Edo and Delta Statesof Nigeria were randomly selected and investigated. The responserate was 91.1% and the result showed that the medical staffcomprised 2.5% of the total workforce, with the large scaleindustries contributing the highest proportion of these. Fourpoint five per cent of the medical staff had formal trainingin occupational health and 15.6% of them visited the factoryshop floor. The doctor:staff ratio in the medium and large scaleindustries were 1:819 and 1:618 respectively. It was found thatall the industries used the health care facilities providedby the government, there were no clinics in all the small scaleindustries and group practice was not used by any of the industriesstudied. Pre-employment medical examinations were carried outin each of the groups of industries (100%, 39.4% and 5%) respectively,as were periodic medical examinations during employment, althoughto a lesser extent (100%, 13.2%, 0%) for the large, medium andsmall scale industries respectively. These finding suggest theavailability of a reasonable standard of health care provisionfor large scale industries and somewhat less availability formedium and small scale industries. Health education of boththe employers of labour, and the employees and the enforcementof existing laws are needed to improve the existing standardof occupational health services.     

Latex glove allergy among hospital employees: a study in the north-west of England

The frequency of use and duration of wearing latex gloves among hospital employees has increased due to concerns about AIDS and hepatitis. In many countries there is increased consciousness about latex sensitization. In the UK, the Medical Device Agency has been monitoring latex allergy for a number of years but has not found any conclusive evidence of any significant problem. We report following a detailed questionnaire study in two hospitals in the north-west of England. A total of 1,827 members of staff were questioned about latex allergy at work. One hundred and twenty-four (7%) of these hospital employees had experienced symptoms strongly suggestive of latex allergy. Of this group, 56 had a-RAST test (IgE specific to latex), which was positive in seven (12.5%). There was a history of atopy in 31%, and a family history of atopy in 17% of the individuals. As a result of the study it was found that 17% (21 of the affected individuals) had already changed their working practice by using latex-free gloves. We were able to increase awareness of latex allergy within the hospitals. Both individuals and health care organizations need to be aware of the problem and hospital organizations should encourage staff to seek guidance to address the problem and, if necessary, to take appropriate measures to improve working practices. Practical guidelines are given with regard to identifying the problem and glove use for hospital staff.     

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.     

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

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

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

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

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.     

A survey of eye trauma and diseases at a teaching hospital: implications for training in occupational ophthalmology in Nigeria

This study explores the amount of occupational ophthalmology that it is possible to encounter within an existing teaching hospital system, as this offers the primary training facilities for resident doctors who expect to specialize in occupational medicine. The study was based on an analysis of ophthalmology patient records available at the University College Hospital, Ibadan, which is Nigeria's largest teaching hospital. One thousand, three hundred and thirty-four patients with eye disease were seen during the 1-year study. Of these, 1052 (78.9%) did not have their occupations recorded. Accidents were the only occupational diagnoses recorded, and this occurred in 75 (5.6%) of cases. The findings indicate that doctors who train in this specialty should gain experience in industries that have sizeable occupational health services, in addition to their formal ophthalmology training, in order to acquire experience in primary and occupational eye care. It is suggested that greater emphasis be placed on occupational ophthalmology in teaching hospitals and that there is a general improvement in completing patients' records: in particular, a patient's occupation should be recorded.     

The application of Ontario human rights legislation to the practice of occupational medicine

Although human rights legislation has important implications for occupational physicians, these implications may be overlooked in the practice of occupational medicine in other countries where human rights legislation may be different. The potential for significant oversights becomes greater as organizations continue to centralize international business support functions, such as occupational health services, operating from a single site. Human rights legislation has important implications with respect to policy decisions upon which an occupational physician has influence. This includes decisions about whether to conduct drug and alcohol testing; the performance of medical examinations; evaluating issues related to health and safety concerns of pregnant employees; and the need to work accommodate those with handicaps as defined by human rights legislation. This article examines the application of the Ontario human rights legislation in these areas.     

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.     

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.     

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.     

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.     

Developing a model for occupational health provision in primary care

This is a report of a survey commissioned by Newcastle and North Tyne Health Authority. The aim of the project was to assess the occupational health needs of both GPs and their staff working in the General Practice in Newcastle and North Tyneside. The aim of the survey has been to obtain information about occupational health needs from general practitioners and their practice managers. The survey design has been a cross-sectional study using questionnaires and practice visits. The information obtained from the practice managers was validated by visits to selected practices. The visits also facilitated a qualitative assessment of occupational health arrangements, training needs and issues that might be important in determining an appropriate model for a primary care-based occupational health service. The results of the needs analysis have shown both general support for an occupational health service and priority areas for such a service. The challenge will be to develop a service that delivers targeted occupational health in a way that is acceptable to all members of staff working in general practice. The service should be seen as a developing service, initially focused to provide a dual role. There will be a core occupational health service for all staff, including GPs, and a specialist service designed to meet the specific identified needs. There will be an opportunity to include the service in an overarching occupational health service within the Tyne and Wear area.
