Workplace investigation is a concept which entails the analysis of hazards inherent in the work as well as assessment of their effects on workers' well-being. The aim of this paper is to evaluate the effectiveness of the workplace investigation method. The newly developed method, called Job Load and Hazard Analysis, has the following characteristics: a job analytic approach; the application of group problem-solving; and cooperation between occupational health professionals, occupational safety personnel, and line management. The method comprises the identification of health hazards, their assessment, and conclusions and proposals as to their prevention and follow-up. The method was tested as part of one constructor's actual occupational health care programme, over a 2.5-year period. The method worked well as a central component of preventive occupational health care. It yielded concrete data that could be applied to make the occupational health care programme better suited to preventing the hazards inherent in the building trade. The contents of the occupational health care programme were clearly enhanced, the number of preventive measures increased, and the organizational climate improved; the workers praised the increased emphasis on safety. More research is needed, eg in other production settings and to determine the most effective utilization of the data gathered by the method.</p>","PeriodicalId":76684,"journal":{"name":"The Journal of the Society of Occupational Medicine","volume":"41 1","pages":"17-22"},"PeriodicalIF":0.0,"publicationDate":"1991-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1093/occmed/41.1.17","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13166992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a cross-sectional interviewer-administered questionnaire it was possible to assess the percentage prevalence of each of 3 facial dermatitis symptoms among both low humidity exposed and non-exposed workers. The two prevalences were compared by calculating a ratio (the percentage prevalence ratio or PPR) of the prevalence of symptoms in the exposed, to that in the non-exposed workforce. A confidence interval (CI) for the PPR was also calculated. For the symptom of itching, the PPR was 1.65 (CI 1.32-2.07) in favour of the study group, whilst for the symptoms of redness and urticaria the PPRs were 1.96 (CI 1.54-2.48) and 2.53 (CI 1.40-4.59) respectively. The occurrence of a greater prevalence of all symptoms in the low-humidity exposed workforce confirms the clinical and laboratory reports of previous workers. A comparison was also made between the two groups of workers of both the severity, and the frequency of occurrence of symptoms. Whilst there was no statistically significant difference between the exposed and non-exposed groups for prevalence of one symptom, among those who had experienced two symptoms there was a PPR of 2.43 (CI 1.37-4.30) between the two groups. Furthermore, among those workers who had experienced all 3 symptoms of facial dermatitis there was a PPR of 3.38 (CI 1.18-8.93) in favour of the low-humidity exposed workforce.(ABSTRACT TRUNCATED AT 250 WORDS)</p>","PeriodicalId":76684,"journal":{"name":"The Journal of the Society of Occupational Medicine","volume":"41 1","pages":"37-40"},"PeriodicalIF":0.0,"publicationDate":"1991-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1093/occmed/41.1.37","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12987712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
