Specialist competencies in occupational medicine: appraisal of the peer-reviewed literature

BACKGROUND: A re-assessment of competencies and therefore learning outcomes for higher specialist training in occupational medicine (OM) is being undertaken. Although peer-reviewed literature on the subject exists, it is limited and needs appraisal. AIMS: To search, and critically appraise the peer-reviewed literature on specialist competencies in OM. METHODS: Systematic search of a range of databases of peer-reviewed literature, followed by criterion based appraisal and categorization of the findings. RESULTS: Two hundred and thirty five papers were found of which only 20 were left after application of the grading and exclusion criteria. These addressed competencies from four perspectives: peer consensus, client, educational and legal. CONCLUSIONS: Limited evidence can be obtained from the peer-reviewed literature on specialist competencies in OM. However, it suggests the main paradigms for deriving these competencies as well as indicating gaps and the manner in which these might be filled.     

Heat Illness in the Army in Cyprus

Heat illness in the British Armed Forces is a significant occupationalrisk. This paper analyzes reports of heat casualties occurringin Episkopi, Cyprus from January 1990 through December 1994.A total of 96 casualties were reported from 48 separate incidents.On seven occasions, three or more casualties occurred concurrently(maximum 19). There were 20 incidents causing 32 casualtiesfrom Cyprus-based units and 28 incidents causing 64 casualtiesfrom units visiting Cyprus. There was a clear seasonal variationof reports with the maximum number of reports occurring fromMay to August. The majority of reported casualties occurredwhen the Wet Bulb Globe Temperature was between 26°C and29°C. Cyprus-based units had most casualties occurring asa consequence of forced marching whereas most casualties fromvisiting units occurred during military field exercise training.Visiting Territorial Army units had the highest incidence ofheat casualties for visiting units. The majority of heat casualtieswere mild; there were only ten severe cases. It was not possibleto identity any particular risk factors applicable to individualsexcept incomplete acclimatization. The study showed that thecurrent guidelines used by the British Armed Forces do not preventall heat casualties. It is not possible to estimate how manycasualties are prevented by the guidelines. All incidents involvinga serious casualty or multiple casualties should be investigatedto determine whether the guidelines should be further amended.     

Influence of residency training on occupational medicine practice patterns

OBJECTIVES: A relatively high proportion of occupational medicine (OM) specialists have not had formal residency training in OM. Members of the Western Occupational and Environmental Medicine Association, a professional organization of OM specialists, completed a postal questionnaire (160 of 561 members). METHODS: Educational background, practice setting, practice activities, and skills considered relevant were compared between those with and without formal training. RESULTS: Both groups had considerable focus in clinical care, musculoskeletal medicine, and workers' compensation. However, those with formal training practice in a broader variety of settings were less likely to have practiced another specialty, and used additional skills (toxicology, industrial hygiene, and epidemiology) in their practices. Formal education appears to create a greater diversity of skills and opportunities, but it does not appear to create a group of physicians disinterested in "front-line" occupational medicine practice. CONCLUSIONS: The data support the need for formal residency programs but also highlight the importance of access to formal training for midcareer physicians.     

Continuing professional development of occupational medicine practitioners: a needs assessment

OBJECTIVE: The aim of this study was to identify elements of occupational medicine practice used on a frequent basis which are considered to be of high priority for continuing professional development (CPD). METHODS: A postal questionnaire covering 28 areas of knowledge or practice was sent to all members of the Society of Occupational Medicine in September 2000. Respondents were asked to allocate scores to the 28 items for both CPD priority and frequency of use. RESULTS: The return rate for questionnaires was 29.5%. There was reasonable agreement between frequency of use and CPD priority ratings for the elements covered in the questionnaire. CONCLUSIONS: Despite the low return rate for questionnaires, this survey has helped identify themes which are important to physicians practising occupational medicine and has also highlighted those which are less important for inclusion in a CPD programme. Some differences in responses were identified between accredited specialists, specialist registrars and non-specialist practitioners of occupational medicine. The findings from this survey should be useful to providers of continuing medical education in planning courses, study days and electronic or distance learning educational packages.     

The burden of psychological symptoms in UK Armed Forces

OBJECTIVE: To assess the prevalence of psychological symptoms during periods of relatively low deployment activity and the factors associated with each psychological health outcome. METHODS: A survey of 4500 randomly selected UK service personnel was carried out in 2002. The questionnaire included the General Health Questionnaire (GHQ-12), the post-traumatic stress disorder checklist (PCL), 15 symptoms and an assessment of alcohol intake. RESULTS: A total of 20% were above cut-offs for GHQ-12, 15% for symptoms, 12% for alcohol intake and 2% for PCL. Gender, age, excessive drinking and smoking were independently associated with most outcomes of interest. Number of deployments was independently associated with multiple symptoms and excessive drinking. High post-traumatic stress disorder score was more frequent in the Army and in lower ranks. CONCLUSIONS: Psychological symptoms are highly prevalent in UK Armed Forces. Many risk factors are associated with measures of psychological ill-health.     

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.     

Quality of clinical supervision as perceived by specialist registrars in a university and district teaching hospital

BACKGROUND: Clinical supervision promotes the professional development of specialist registrars (SpRs). Our objective was to investigate and compare the perceived quality of supervision (PQS) in a university teaching hospital (UTH) and a district teaching hospital (DTH) and to identify aspects of supervision that could be improved. METHODS: The Cleveland Clinic's teaching effectiveness instrument (CCTEI) was used to measure the quality of supervision of attending doctors. Fifteen items reflecting good teaching ability were rated on a 5-point Likert-scale (1-5 = poor-excellent). RESULTS: SpRs rated 47 attending doctors using the CCTEI. A total of 416 ratings were obtained. Overall, the mean PQS was 3.85 (SD = 0.29) in the DTH and 3.56 (SD = 0.44) in the UTH (P = 0.02). A significant difference in PQS was found in 6 items. The supervisors in the DTH scored better on all these items. The best predictor of PQS was the item 'Organises time to allow for both teaching and care giving'. CONCLUSIONS: Overall, PQS was better in the DTH compared to the UTH. In both settings, generating a good learning environment and respecting the autonomy of the SpRs scored favourably. Supervisory roles focusing on improving cost-effective practice and communicative skills need more emphasis.     

Quality of training in public health in the UK: results of the first national training audit

OBJECTIVES: Since 1997, UK public health training has undergone major changes, including the creation of specialist registrars (SpRs), introduction of a competency framework, admission of non-medical (specialist) trainees and National Health Service organizational change. It was therefore considered timely to audit the quality of this training. STUDY DESIGN: Cross-sectional survey of all UK public health trainees, conducted in April 2003. METHODS: The survey questions were based on 75 previously identified standards, with three sections: induction (30 standards), health protection (13 standards) and general training (32 standards). Results were calculated for the UK. Deaneries were compared on 10 key standards, as was the training of SpRs and specialist trainees. RESULTS: Two hundred and ninety responses were received (62% response rate). Only 16 (21%) of 75 standards were met by at least 80% of respondents, with problems in induction, health protection, secretarial facilities and examination support. Across 10 key standards (including initial welcome, trainer support, breadth/relevance of work and facilities), 59% indicated that their training had met at least eight standards. Results for individual deaneries were significantly different (P = 0.02), although 13 of 16 had median scores of eight out of 10, or over. Deaneries with specialists scored lower than those without (median scores eight vs nine, P = 0.003). Median specialist and SpR scores on the 10 key standards were seven and eight, respectively (P<0.001). In addition, SpRs were more likely to be 'on-call' [odds ratio (OR) = 66.8, 95% confidence interval (CI) 17.2-259.4, P<0.001] and to feel prepared for this role (OR = 10.7, 95% CI 1.4-79.8) than specialists. CONCLUSION: This was the first UK National Audit of Public Health Training. Few standards were achieved amongst respondents, although the levels set may be considered to be high and the response rate (62%) was less than optimal, potentially biasing results. Despite these caveats, recent organizational change in England appears to have led to significant training disruption among respondents. Nevertheless, repeating such an audit annually within deaneries could help to improve public health training throughout the UK.     

Occupational risk factors for ill health in Gulf veterans of the United Kingdom

OBJECTIVES: To study the association between occupational factors specific to the Armed Forces (rank, functional roles, Service, regular or reservist status and deployment factors) and symptomatic health problems in Gulf veterans, after sociodemographic and lifestyle factors have been accounted for. DESIGN: A postal cross sectional survey of randomly selected UK Gulf veterans was conducted six to seven years after the Gulf conflict. Physical ill health was measured using the Fatigue Questionnaire and a measure of the Centers for Disease Control and Prevention (CDC) multi-symptom syndrome. Psychological ill health was measured using the General Health Questionnaire and a post-traumatic stress measure. SETTING: Population of servicemen who were serving in the UK Armed Forces during the Gulf conflict between 1 September 1990 and 30 June 1991. PARTICIPANTS: 3297 Gulf veterans. MAIN RESULTS: In multivariate logistic regression, there was an inverse relation between higher rank and psychological and physical ill health (test of trend: General Health Questionnaire, p=0.004; post-traumatic stress, p=0.002; fatigue, p=0.015; CDC case, p=0.002). Having left the Armed Forces was associated with a two to three times increase in reporting ill health. Of the deployment factors, there was a weak association between being deployed as an individual reinforcement in a combat role and post-traumatic stress but there was no association between receiving pre-deployment training or post-deployment leave and ill health. Marital status and smoking were associated with psychological and physical ill health. CONCLUSIONS: Rank was the main occupational factor associated with both psychological and physical ill health in Gulf veterans. This may parallel the associations between socioeconomic status and morbidity in civilian populations. Ill health seems to be greater in those who return to civilian life. Sociodemographic factors also seem to be important in ill health in Gulf veterans.     

Interventions: what works, what doesn't?

This review examines the evidence for the effectiveness of occupational stress interventions. Three types of interventions are considered: psychotherapy and counselling services, stress management training, and organizational level interventions. The review concludes that there is good evidence that, for specific mental health problems, formal psychotherapy is effective in terms of reducing individual symptoms. Other forms of intervention have been less well evaluated. The evidence that exists indicates that counselling services and stress management training have modest but short-term effects on individual well-being. Organizational interventions have insignificant effects on individual well-being and on organizational outcomes.     

Receptionists' perceptions of violence in general practice

BACKGROUND: Violence and threatening behaviour towards health care employees is a recognized hazard. There is a lack of research into the perceptions of general practice (GP) receptionists about this important workplace hazard. AIM: To determine the factors that influence reception staff perceptions regarding the risk of future violent and threatening incidents at work. METHODS: A cross-sectional survey using a self-administered postal questionnaire was carried out among reception staff working in 49 GPs in two UK National Health Service Primary Care Trusts. RESULTS: Forty-nine (72%) practices agreed to participate. Two hundred and seven (68%) reception staff participated. Receptionists who reported having been threatened or attacked in the past 12 months were more likely to be worried about being threatened [odds ratio (OR) 4.9; 95% confidence interval (CI) 2.0-11.8] or attacked (OR 4.6; 95% CI 1.8-11.2) in the future. Receptionists with higher neuroticism scores were more worried about the future possibility of violence. Staff who felt safe and supported at work (P = 0.003) and staff who had lower background sources of stress at work (P < 0.001) were less likely to feel they would be threatened or attacked at work. Staff who had received training about violent and abusive incidents felt safer at work (OR = 1.27; 95% CI 1.04-1.55). CONCLUSION: Previous episodes of threats or attacks at work make receptionists more worried about future episodes. Factors which reduce reception staff anxieties about violence and threat at work are working in a supportive environment where work stressors are controlled and receiving training on how to deal with violent, threatening and difficult behaviour.     

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.     

Risk perception and attitudes towards HIV in Serbian health care workers

BACKGROUND: Health care workers (HCWs) are at risk of occupational exposure to human immunodeficiency virus (HIV). AIM: To investigate the perception of professional risk from, and the knowledge, attitudes and practice of HCWs to HIV and AIDS in Serbia. METHODS: Cross-sectional study of 1,559 Serbian HCWs using self-administered anonymous questionnaires. Chi-square testing and multiple logistic regression analysis were applied. RESULTS: Eighty-nine per cent of HCWs believed that they were at risk of acquiring HIV through occupational exposure. The perception of professional risk was higher among HCWs frequently exposed to patients' blood and body fluids (OR 7.9, 95% CI 4.4-14.5), who used additional personal protection if the HIV status of patient was known (OR 2.6, 95% CI 1.5-4.6), who had experienced sharp injuries within the last year (OR 1.9, 95% CI 1.0-3.8) or who had been tested for HIV (OR 2.1, 95% CI 1.2-3.5), and among HCWs who had treated HIV-positive patients (OR 1.7, 95% CI 1.1-2.8). The majority of respondents had deficient knowledge about modes of HIV transmission. Attitudes towards HIV-positive patients were significantly different by occupation. Seventy per cent of HCWs used appropriate protection during their daily work with patients. CONCLUSIONS: HCWs require specific educational programmes and training protocols to ensure that they are adequately protected when carrying out high quality care.     

The prevalence of eating disorders in female health care students

Previous research has suggested a raised prevalence of eating disorders amongst female medical students. This study aimed to test the belief, commonly held by occupational physicians, that there is also an increased prevalence of eating disorders amongst female applicants to nurse training. If correct, it implies the need for additional support and may predict increased failure to complete the course. Three groups of female students were compared: applicants to a university nurse training course, first-year medical students and a comparison group of first-year university students on courses not related to health care. Possible eating disorders were identified using two self-report instruments, the EAT-26 and the BITE questionnaires, and the body mass index. No significant statistical difference was found in the prevalence of eating disorders between the three groups, using the above measures. After controlling for age and ethnicity, 20% of the nurse applicants were found to have disordered eating patterns meriting further investigation, compared with 19% of medical students and 21% of arts students. The nursing students are being followed up to compare the progress of those with and without disordered eating patterns.     

Is there value in routinely obtaining a report from the general practitioner as part of pre-entry health screening of students for nursing studies?

BACKGROUND: Reports from general practitioners (GPs) are requested on applicants for nurse training, but there is no published evidence of the merit of this practice. AIMS: To assess the benefit of GP report in health assessments of student nurse applicants. METHODS: An audit was made of information obtained by health declaration form (HDF), nurse's assessment, GP report and, when performed, a physician's assessment for each applicant. Agreement between the health questionnaire and GP report was analysed by kappa statistics. RESULTS: Of 254 applicants, 246 (97%) were declared 'fit to work', four (1.6%) were deemed 'fit with restrictions' and four (1.6%) were considered 'unfit to work'. The most common problems declared were psychiatric and skin problems. The agreement between health declaration and the information provided by GPs was classed as almost perfect for diabetes and only fair to moderate for all other measures. The reports provided additional information on problems not declared by applicants, but all of these were passive problems. The four unfit candidates all had psychiatric illness, but in all cases the occupational health assessment was sufficient to make this decision or to request further information. In the 'fit with restrictions' category, three of the four GP reports (75%) helped in correctly assigning the applicants to this category. In one of these eight cases a passive problem had not been declared. CONCLUSIONS: The additional information in GP reports does not affect the conclusion regarding fitness for training in most cases and does not provide sufficient information to merit it being sought routinely.     

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.
