[Quality of medical diagnosis in sick leave certificates for non-occupational diseases and injuries].

OBJECTIVE: To evaluate the quality of medical diagnosis in the sick leave certificate. DESIGN: Retrospective, observational study. SETTING: Castelldefels Primary Care Centre, Barcelona, Spain. MEASUREMENTS AND INTERVENTIONS: 205 sick leave episodes of patients reported as non-occupational diseases and injuries were analyzed. The diagnosis of the sick leave certificate was checked against the clinical report carried out by the same physician who made out the sick leave certificate. To assess the quality of medical diagnosis, sensitivity, positive predictive value and the percentage of positive agreement were calculated. The variability of these indicators was also assessed according to the duration of the sick leave episode. RESULTS: Simple agreement between the diagnoses of the sick leave certificate and the clinical report was 92%. The sensitivity of the sick leave certificate in relation to the clinical report by diagnostic group ranged from 75% to 97%; positive predictive value, from 81% to 100%; and the percentage of positive agreement, from 86% to 97%. Short-term sick leave episodes (< or =15 days) had lower values than long-term sick leave (>15 days). CONCLUSIONS: Our findings confirm that the quality of diagnosis on the sick leave certificate is high. The availability of more medical information about the reasons for the sick leave episode does not modify the quality of the diagnosis substantially.

Associations between temporary employment and occupational injury: what are the mechanisms?

OBJECTIVE: To determine whether observed higher risks of occupational injury among temporary workers are due to exposure to hazardous working conditions and/or to lack of job experience level. METHODS: Data systematically recorded for 2000 and 2001 by the Spanish Ministry of Labour and Social Affairs on fatal and non-fatal traumatic occupational injuries were examined by type of employment and type of accident, while adjusting for gender, age, occupation, and length of employment in the company. In the study period there were 1500 fatal and 1 806 532 non-fatal traumatic occupational injuries that occurred at the workplace. Incidence rates and rate ratios (RR) were estimated using Poisson regression models. RESULTS: Temporary workers showed a rate ratio of 2.94 for non-fatal occupational injuries (95% CI 2.40 to 3.61) and 2.54 for fatal occupational injuries (95% CI 1.88 to 3.42). When these associations were adjusted by gender, age, occupation, and especially length of employment, they loose statistic significance: 1.05 (95% CI 0.97 to 1.12) for non-fatal and 1.07 (95% CI 0.91 to 1.26) for fatal. CONCLUSIONS: Lower job experience and knowledge of workplace hazards, measured by length of employment, is a possible mechanism to explain the consistent association between temporary workers and occupational injury. The role of working conditions associated with temporary jobs should be assessed more specifically.

Validation of an asthma questionnaire for use in healthcare workers.

BACKGROUND: Previous studies have described increased occurrence of asthma among healthcare workers, but to our knowledge there are no validated survey questionnaires with which to study this occupational group. AIMS: To develop, validate, and refine a new survey instrument on asthma for use in epidemiological studies of healthcare workers. METHODS: An initial draft questionnaire, designed by a multidisciplinary team, used previously validated questions where possible; the occupational exposure section was developed by updating health services specific chemical lists through hospital walk-through surveys and review of material safety data sheets. A cross-sectional validation study was conducted in 118 non-smoking subjects, who also underwent bronchial challenge testing, an interview with an industrial hygienist, and measurement of specific IgE antibodies to common aeroallergens. RESULTS: The final version consisted of 43 main questions in four sections. Time to completion of the questionnaire ranged from 13 to 25 minutes. Test-retest reliability of asthma and allergy items ranged from 75% to 94%, and internal consistency for these items was excellent (Cronbach's alpha > or = 0.86). Against methacholine challenge, an eight item combination of asthma related symptoms had a sensitivity of 71% and specificity of 70%; against a physician diagnosis of asthma, this same combination showed a sensitivity of 79% and specificity of 98%. Agreement between self-reported exposures and industrial hygienist review was similar to previous studies and only moderate, indicating the need to incorporate more reliable methods of exposure assessment. Against the aerollergen panel, the best combinations of sensitivity and specificity were obtained for a history of allergies to dust, dust mite, and animals. CONCLUSIONS: Initial evaluation of this new questionnaire indicates good validity and reliability, and further field testing and cross-validation in a larger healthcare worker population is in progress. The need for development of more reliable occupational exposure assessment methods that go beyond self-report is underscored.

Distribution of sickness absence in the European Union countries.

AIMS: To determine the sickness absence frequency in European Union (EU) countries. METHODS: Sickness absence was measured by questionnaire using the Third European Survey on Working Conditions. Employees were considered to have sickness absence if they reported to be absent at least one day in the past 12 months because of an accident at work, work related problems, or by other health problems. RESULTS: Sickness absence percentages were lower in Southern European countries compared with Central and Northern European countries, and, in general, slightly higher in men than in women. CONCLUSION: This is the first description of sickness absence in each of the 15 EU countries. Examination of the sickness absence patterning between EU countries could indicate countries where important lessons to reduce sickness absence are to be learned and diffused across the EU.

[Public health professionals and professional competences debate].

Despite its historical contribution to the improvement of health, public health occupies a marginal position in health systems. This lack of correspondence between impact and power is related in part to its scarce recognition as a profession, and in consequence to the lack of recognition of the professionals in the field. The strengthening of the public health profession requires recognising the coherence of their objectives and scientific basis, but it also requires the establishment of mechanisms to guarantee professional competence. Generally, the institutionalisation of these necessary mechanisms to articulate public health objectives into effective professional practice has been lacking. In other words, the so-called professional competencies lacked development in public health. Progress in this strategy calls for the definition of the professional content based on a functional analysis of public health. That is, an analysis of the functions that these professionals must contribute to society and of the specific activities necessary to achieve the desired outcomes. The aim of this work is to stimulate a debate along these lines taking into account the experiences of other countries. The authors propose to reconsider a further reconstruction of public health, based on an analysis of its objectives, functions and competences, in order to grow away from its marginal position, and improve its social function.

[Emotional disorders in the working population: an emerging problem in occupational health?].

BACKGROUND: To know the prevalence of emotional disorders in a working population. SUBJECTS AND METHOD: Workers in four companies: construction (A), automobile components (B), electrical and electronic systems (C) and management services (D). The design of the study was cross-sectional with the GHQ-28 questionnaire. RESULTS: The prevalence fluctuated between 8,4% (A) and 24,0% (D). Sex, age, educational level and occupation showed significance differences in some companies. CONCLUSIONS: The results suggest an important prevalence of emotional disorders that likely increase as there will be more firms of services.

Occupation and pancreatic cancer in Spain: a case-control study based on job titles. PANKRAS II Study Group.

BACKGROUND: Occupational exposures may increase the risk of exocrine pancreatic cancer. This study aimed to identify occupations that in Spain may be associated with such risk. METHODS: Incident cases of pancreatic cancer and hospital controls were prospectively identified and interviewed during their hospital stay. Occupational history was obtained by direct interview with the patient and was available for 164 (89%) of 185 pancreatic cancer cases and for 238 (90%) of 264 controls. Occupations were coded according to the Spanish version of the International Standard Classification of Occupations 1988. RESULTS: A significant increased odds ratio (OR) was observed in men for 'physical, chemistry and engineering science technicians'. Elevated risks were also found for 'metal moulders, sheet-metal workers, structural metal workers, welders and related workers', 'painters and varnishers' and 'machinery mechanics and fitters'. 'Agricultural workers' did not present an increased risk for pancreas cancer in men. In women, however, high OR were observed for 'agricultural workers' and for 'textile and garment workers'. Most associations remained unchanged after considering long duration of the exposure and the period 5-15 years before diagnosis. CONCLUSIONS: Few occupations were at increased risk for pancreatic cancer, and the associations observed are in accordance with previous studies. The increases in risk observed for women in agricultural and textile jobs, and for men in the manufacture of dyes and pigments may deserve further attention.

How do types of employment relate to health indicators? Findings from the second European survey on working conditions.

STUDY OBJECTIVE: To investigate the associations of various types of employment with six self reported health indicators, taking into account the part played by demographic variables, individual working conditions and four ecological indicators at the country level. DESIGN: Cross sectional survey (structured interview) of a sample of the active population of 15 European countries aged 15 years or over. Main independent variables were nine types of employment categorised as follows: small employers, full and part time permanent employees, full and part time fixed term employees, full and part time sole traders and full and part time temporary contracts. Main outcome measures were three self reported health related outcomes (job satisfaction, health related absenteeism, and stress) and three self reported health problems (overall fatigue, backache, and muscular pains). Logistic regression and multilevel models were used in the analyses. SETTING: 15 countries of the European Union. PARTICIPANTS: 15 146 employed persons aged 15 or over. MAIN RESULTS: Precarious employment was consistently and positively associated with job dissatisfaction but negatively associated with absenteeism and stress (as compared with full time permanent workers). Fatigue, backache and muscular pains also tended to be positively associated with precarious employment, particularly with full time precarious employment. Small employers reported high percentages of stress and fatigue, but absenteeism was relatively low. Sole traders generally reported high percentages of all outcomes, except for absenteeism, which was low. For each type of employment (except temporary contracts), full time workers tended to report worse health outcomes than part time workers. Patterns were generally consistent across countries. Associations persisted after adjustment for individual level working conditions and were not modified by country level variables. CONCLUSIONS: This study is the first to examine the relations between various types of employment and six health related indicators for all 15 member states of the European Union. Suggestive patterns worthy of further exploration have been found. Standardised definitions of types of underemployment and health related outcomes, more potent epidemiological designs and the inclusion of socioeconomic information (for example, social security systems, incapacity benefit schemes) at the regional level are proposed for inclusion in further research.

Risk of pancreatic cancer and occupational exposures in Spain. PANKRAS II Study Group.

The objective of the study was to analyse the relationship between occupational exposures and risk of pancreatic cancer. Incident cases of pancreatic cancer and hospital controls were prospectively identified and interviewed during the hospital stay. Occupational history was obtained by direct interview with the patient, and was available for 164 (89%) of 185 pancreatic cancer cases, and 238 (90%) of 264 controls. Two industrial hygienists evaluated exposures to 22 suspected carcinogens previously associated with pancreatic cancer. Occupational exposures were also assessed using the Finnish job-exposure matrix (FINJEM). For each type of pesticide group, moderately increased odds ratios (OR) were apparent in the high-intensity category, highest for arsenical pesticides (OR=3.4; 95% CI 0.9-12.0), and 'other pesticides' (OR=3.17; 95% CI 1.1-9.2). ORs for aniline derivatives, and dyes and organic pigments, were also higher for high-intensity exposure, and increased when lagged and restricted to long duration of exposure. ORs above 3 were observed for the following agents evaluated by FINJEM: pesticides, benzo[a]pyrene, lead, volatile sulphur compounds, and sedentary work. Whilst generally negative, results lend moderate support to the hypothesis of an association between exposure to some pesticides and pancreatic cancer. Larger studies could address the potential for these compounds to modify the carcinogenic risk of other environmental exposures. Suggestive increases in risk from aniline derivatives, dyes and organic pigments, and benzo[a]pyrene may also deserve further attention.
