  Issues surrounding sickness absence are of interest due to growing awareness of the costs to employers and the UK economy, a greater understanding of the interaction between health and work, andIssues surrounding sickness absence are of interest due to growing awareness of the costs to employers and the UK economy, a greater understanding of the interaction between health and work, and increasing evidence that work is beneficial to physical and mental well-being. The Health & Occupation Reporting network in General Practice (THOR-GP) is a national source of information on work-related sickness absence. To assess the factors influencing work-related sickness absence in the UK. General practitioners (GPs) report cases of work-related ill-health via an online web form. Sickness absence information reported with each case was compared by demographic information, diagnosis/symptom and employment factors. Between 2006 and 2009, THOR-GP received 5683 case reports of work-related ill-health; 53% were musculoskeletal diagnoses and 31% were mental ill-health diagnoses. Over half (56%) of cases reported had associated sickness absence. Diagnosis had a highly significant influence on the occurrence of any associated sickness absence. Eighty-one per cent of mental ill-health cases were reported to result in sickness absence compared to 50% of musculoskeletal cases. Public sector employees incurred sickness absence more frequently than those from the private sector. Industries with the highest mental ill-health incidence rates had sickness absence episodes most frequently. Within employment groups, levels of sickness absence were inversely proportional to the level of self-employment. These data reported by GPs with vocational training in occupational medicine may help to inform policy decisions targeting work-related exposures and the management of sickness absence, thereby reducing the UK burden of work-related sickness absence.

  Construction workers are at increased risk of work-related ill-health (WRI) worldwide. To compare the incidence of medically reported WRI in occupations within the UK construction industry accordingConstruction workers are at increased risk of work-related ill-health (WRI) worldwide. To compare the incidence of medically reported WRI in occupations within the UK construction industry according to job title. We calculated standardized incidence rate ratios (SRRs) using WRI cases for individual job titles returned to The Health and Occupation Reporting network by clinical specialists and UK population denominators. We counted frequencies of reported causal exposures or tasks reported by clinical specialists, occupational physicians and general practitioners. We found significantly increased incidence of WRI compared with other workers in the same major Standard Occupational Classification, i.e. workers with similar levels of qualifications, training, skills and experience, for skin neoplasia in roofers (SRR 6.3; 95% CI: 3.1-13.1), painters and decorators (2.1; 95% CI: 1.2-3.6) and labourers in building and woodworking trades (labourers, 6.6; 95% CI: 3.2-13.2); contact dermatitis in metal workers (1.4; 95% CI: 1.1-1.7) and labourers (1.6; 95% CI: 1.1-2.3); asthma in welders (3.8; 95% CI: 2.8-5.0); musculoskeletal disorders in welders (1.7; 95% CI: 1.1-2.8), road construction operatives (6.1; 95% CI: 3.8-9.6) and labourers (2.5; 95% CI: 1.7-3.7); long latency respiratory disease (mesothelioma, pneumoconiosis, lung cancer, non-malignant pleural disease) in pipe fitters (4.5; 95% CI: 3.2-6.2), electrical workers (2.7; 95% CI: 2.4-3.2), plumbing and heating engineers (2.3; 95% CI: 1.9-2.7), carpenters and joiners (2.7; 95% CI: 2.3-3.1), scaffolders (12; 95% CI: 8-18) and labourers (3.3; 95% CI: 2.6-4.1). UK construction industry workers have significantly increased risk of WRI. These data in individual construction occupations can be used to inform appropriate targeting of occupational health resources.

  Noise-induced hearing loss (NIHL) from prolonged occupational exposure to noise continues to rank among the top worldwide work-related ill-health problems. To provide an overview of incident casesNoise-induced hearing loss (NIHL) from prolonged occupational exposure to noise continues to rank among the top worldwide work-related ill-health problems. To provide an overview of incident cases based on work-related audiological ill-health data collected over a 9-year period from occupational physicians (OPs), audiological physicians (APs), general practitioners and otorhinolaryngologists. Analysis of numerator data reported by physicians to surveillance schemes within The Health and Occupation Reporting network (THOR). The actual cases were multiplied by the sampling ratio to provide estimated numerator numbers, followed by calculation of incidence rates using denominator data derived from the Labour Force Survey and from surveys of participating OPs. Two thousand five hundred and eighty-two estimated cases (2584 estimated diagnoses) were received from OPs (Occupational Physicians Reporting Activity [OPRA]), and 2192 estimated cases (3208 estimated diagnoses) of work-related audiological ill-health were received from consultant APs [Occupational Surveillance Scheme for Audiological physicians (OSSA)] from 1998 to 2006. Cases where the causal agent was noise exposure (NIHL and tinnitus) made up of 95 and 97% of all cases reported to OPRA and OSSA, respectively. The annual average incidence rate for noise-induced audiological disorders was 7.9 [95% confidence interval (CI) 4.6-11.1] per 100 000 persons employed (OPRA) and 0.8 (95% CI 0.7-1.0) per 100 000 persons employed (OSSA). Workers with the highest incidence were older males employed in public administration and defence and the manufacture of metals. THOR data show that diagnoses related to work-related noise exposure (NIHL/tinnitus), as reported to THOR, remain important health problems, despite preventive measures being in place.

  Work-related skin and respiratory disease still constitute an important part of the work-related ill-health (WRIH) burden of Great Britain (GB). It is therefore important to be able to accuratelyWork-related skin and respiratory disease still constitute an important part of the work-related ill-health (WRIH) burden of Great Britain (GB). It is therefore important to be able to accurately quantify the true incidence of these two groups of disease. To improve the accuracy of the methodology to estimate clinical specialist incidence rates, with a focus on skin and respiratory disease. Specifically, we sought to estimate the number of additional cases not captured by voluntary surveillance through The Health and Occupation Reporting (THOR) network and provide a better estimation of the true incidence of work-related skin and respiratory disease in GB. Cases not captured by THOR in 2005-2007 due to non-participation of eligible clinical specialists and due to <100% response rates by THOR participants were estimated, and the numerator adjusted accordingly. Adjusted incidence rates were calculated using Labour Force Survey data as the denominator. During 2005-2007, 62% of skin cases and 60% of GB respiratory cases were likely to have been captured by THOR. After adjustment, dermatologist-derived incidence rates for skin disease were raised from 9 to 14 per 100,000 employed, while those for respiratory disease were raised from 10 to 17 per 100,000 employed. We have provided a significant improvement in the surveillance-based methodology used to estimate the number of cases of WRIH captured by THOR and hence enabled more accurate estimations of GB incidence rates for clinical specialist-reported WRIH.

  Self-reported work-related ill-health (WRI) statistics suggest that agricultural workers in the UK are at an increased risk of musculoskeletal disorders (MSD), skin and respiratory disease. However,Self-reported work-related ill-health (WRI) statistics suggest that agricultural workers in the UK are at an increased risk of musculoskeletal disorders (MSD), skin and respiratory disease. However, there is little comprehensive medically reported information on WRI in the UK agricultural sector. Cases of WRI within the UK from 2002 to 2008, as reported to The Health and Occupation Reporting (THOR) network by occupational physicians, clinical specialists and general practitioners, were analysed. Directly standardized incidence rate ratios (SRRs) for the agricultural sector versus all other sectors were calculated for dermatological, musculoskeletal, respiratory and psychological illness, using as the standard population the UK working population as estimated from the Labour Force Survey. During 2002-08, 471 cases within the agricultural sector were reported to THOR (2% of all cases). Based on reports by clinical specialists, male agricultural workers aged <65 years had significantly raised SRRs for MSD (2.3, 95% CI 1.6-3.3), allergic alveolitis (32, 95% CI 19-51), asthma (1.9, 95% CI 1.2-3.0) and skin neoplasia (7.9, 95% CI 5.8-10.9) and a significantly reduced SRR for asbestos-related respiratory disease (0.4, 95% CI 0.2-0.7). Reports of mental ill-health in agricultural workers were low. These medically reported incidence data provide information on WRI in the UK agricultural sector. Consistent with other sources, there are increased risks for asthma, allergic alveolitis and MSD and a reduced risk for mental ill-health. The raised incidence of skin cancer requires confirmation and further comparison with reliable estimates of the incidence in the UK workforce.

  OBJECTIVES: To establish the reliability and validity of work-related mental ill-health diagnoses. BACKGROUND: A UK-based surveillance scheme for work-related ill-health involving occupationalOBJECTIVES: To establish the reliability and validity of work-related mental ill-health diagnoses. BACKGROUND: A UK-based surveillance scheme for work-related ill-health involving occupational physicians (OPs) reporting suggests that mental ill-health incidence is increasing by around 13% per year, with anxiety, depression and "other work-related stress" being the most common diagnoses. There have been no studies of the validity and reliability of such diagnoses. Given the existence of a large network of psychiatrists (PSYs) also involved in surveillance of work-related ill-health, an opportunity arose to measure the concurrent validity and reliability of work-related mental ill-health diagnoses. METHODS: 100 anonymised summaries of cases previously reported by OPs or PSYs were collected; each was sent to 5 PSYs and 5 OPs, who assigned a diagnosis and judged whether the case was work-related. Concurrent validity of the ill-health aspect of the diagnoses, and of the opinion as to work-relatedness, was assessed by comparing the overall classifications of cases by OPs and PSYs. Reliability of the diagnostic classification was measured by kappa matrices. RESULTS: Diagnostic proportions for PSYs and OPs demonstrated good agreement for anxiety, depression, anxiety plus depression and "stress" (11%, 34%, 27%, 14%) and (14%, 30%, 27%, 17%), respectively. In both groups, kappa coefficients were high for a psychotic diagnosis (0.78, 95% CI: 0.74 to 0.83), but not as high for anxiety (0.27, 95% CI: 0.23 to 0.32), depression (0.34, 95% CI: 0.29 to 0.38) and "stress" (0.15, 95% CI: 0.10 to 0.19). The odds ratio of classifying a case as work-related among PSYs compared to OPs was 2.39 (95% CI: 1.68 to 3.38), p<0.001. CONCLUSIONS: The overall agreement between OPs and PSYs on mental ill-health diagnoses suggests that OP diagnoses are valid for epidemiological purposes. However, the within-group reliability of the diagnosis "stress" is low. Given differences in judgements about work-relatedness, further research is needed to investigate this aspect of a diagnosis.

These rates allowBACKGROUND: Estimated incidence rates for occupational skin disease in the U.K. are provided by voluntary surveillance schemes involving dermatologists and occupational physicians. These rates allow monitoring of occupational dermatoses, and intervention planning aimed at reducing workplace risks. OBJECTIVES: To summarize occupational skin disease reported to The Health and Occupation Reporting (THOR) network (2002-2005), and to provide baseline information for comparison with future studies of occupational skin disease in the U.K. and beyond. METHODS: Incidence rates for occupational dermatoses were calculated using THOR data as numerators, and Labour Force Survey data or information from the most recent U.K. survey on provision of occupational physician services as denominators. RESULTS: In the U.K. (2002-2005) the average annual incidence rate of work-related skin disease reported to THOR by dermatologists was 91.3 [95% confidence interval (CI) 81.8-101.1] per million, and by occupational physicians was 316.6 (95% CI 251.8-381.3) per million. Most reports were of contact dermatitis: dermatologists 68.0 (95% CI 59.8-76.2) per million, occupational physicians 259.7 (95% CI 200.8-318.6) per million. CONCLUSIONS: Information produced by THOR is an important source for calculating incidence rates of occupational skin disease. A range of reporting groups should also be used when building an overall picture of occupational skin disease incidence in the U.K.

AIMS: To investigate physicians' beliefs about assessment of occupational attribution for work-related musculoskeletal disorders. METHODS: A questionnaire survey was sent to 526 occupational physicians and 248 rheumatologists on: characteristics of cases seen, assessment of work attribution, definition of work-relatedness and threshold for case reporting. Continuous variables were analysed by mean, standard deviation, an independent two-sample t-test and the Mann-Whitney test. Mean and median values were calculated and Spearman's rank test was applied to ranked data. RESULTS: Questionnaires were completed by 68% occupational physicians and 64% rheumatologists. Both groups of physicians believed that 'history of onset in relation to workplace changes' and 'symptoms consistent with work exposure' were the most important factors suggesting work attribution. They considered that the most important objective of a reporting scheme was detection of trends in disease incidence and that the most suitable criteria for defining work-relatedness was the probability that exposure at work 'more likely than not' caused the condition (mean 0.73; SD=0.17), in a perceived likelihood scale (0-1). CONCLUSION: There was a strong agreement between occupational physicians and rheumatologists on questions about work-relatedness and musculoskeletal disorders. The level of probability for concluding work-relatedness has been quantified.

Reporting of infectious disease byBACKGROUND: Infectious diseases remain an important cause of self-reported work-related illness, with socio-economic consequences, including sickness absence. Reporting of infectious disease by occupational and specialist physicians is an important tool in the investigation of occupationally related infections and is relevant in their management. AIMS: To examine the reporting of cases of infectious disease by occupational and specialist physicians to schemes collecting data on occupational ill-health. METHODS: Cases of infectious disease reported by occupational and specialist physicians to the UK based schemes, Occupational Disease Intelligence Network (ODIN) and The Health and Occupation Reporting network (THOR), from 2000 to 2003 were analysed by reporting patterns, diagnosis, single case or outbreak reporting and industry. RESULTS: The total number of estimated cases of infectious disease reported to ODIN and THOR from 2000 to 2003 was 5606; 74.9% cases were diarrhoeal disease, and 11.1% scabies. The majority (81.4%) of cases were reported in SIDAW, where the participation rate for reporters was 55%. Reporting rates were much higher in OPRA, SWORD and EPIDERM (ranging from 86 to 96%). The most frequently reported industrial sectors were social care (39.5%) and health (29.4%); while the manufacture of chemical products contributed 4.3% overall, but 33.8% to estimated cases in OPRA. CONCLUSIONS: Despite limitations related to under reporting, the occupational and specialist physician schemes in ODIN and THOR provide data that may be used to look at patterns of case reporting for occupational ill-health, including infectious disease. The reporting schemes also provide an important means of alerting peers about potential novel causes, precipitating factors, or industrial sectors associated with occupational disease.

Data collection and dissemination has hitherto been paper-based. AIMS: To elicit the opinion of existing reporters in THOR on electronic exchange of information and to assess the practical capabilities of the same reporters to participate in electronic communication. METHODS: A mail-based questionnaire of randomly selected THOR reporters using closed format questions. RESULTS: The response rate to the questionnaire was 66% (253/383). Almost half (47%) of the responders wanted dissemination of information solely in an electronic form, 35% favoured paper-based reports, while 16% wanted both paper and electronic reports. Two-thirds (66%) would make use of electronic archives of reports and 59% would use this facility to resolve questions by accessing accumulated data. The majority (82%) read e-mail more than once a week and 34% browsed the web as frequently. However, 5% did not have e-mail and 6% never browsed the web. Most responders judged their internet connectivity to be rapid (68%) and convenient (83%), and 91% could receive e-mail attachments. CONCLUSIONS: Most responders have the skills and infrastructure required to engage in electronic information exchange, and are favourably disposed to electronic means of communication. However it is also relevant to note that one-third of responders have a preference for the existing paper-based system.
