BACKGROUND The objective of this study was to develop a strategy to optimize medical health surveillance protocols for administrative employees using video display terminals (VDTs). A total of 2453 medical examinations were analysed for VDT users in various sectors. From these data, using Bayesian statistics we inferred which factors were most relevant to medical diagnosis of the main disorders affecting VDT users. This information was used to build an influence diagram to evaluate the time and monetary costs associated with each diagnostic test and define an optimal protocol strategy based on occupational risks. RESULTS Musculoskeletal and ophthalmological diseases were identified as the most frequent disorders among VDT users. The Bayesian network inferred age, sleep quality, activity level, smoking and the consumption of alcohol as risk factors. The blood count was the most costly test (5.23 USD/employee) and the second most costly test in time terms (4 min/employee), yet is a diagnostic test that has little influence on the medical decision regarding an employee's capacity to perform their job. CONCLUSIONS Current occupational health surveillance protocols for VDT users may lead to expenditure that is 54% greater than necessary. For many employees and employers, failure to perform a wide range of medical tests for occupational health surveillance purposes is subjectively perceived as a threat to health. Awareness needs to be raised of the appropriate role of different health areas, so as to optimize diagnostic efficiency on the basis of greater flexibility.

行政视频显示终端员工健康监控策略的比较分析。

背景技术本研究的目的是开发一种策略，以优化使用视频显示终端（VDT）的行政员工的医疗健康监视协议。总共对不同行业的VDT用户进行了2453次体检。从这些数据，使用贝叶斯统计，我们可以推断出哪些因素与影响VDT用户的主要疾病的医学诊断最相关。该信息用于构建影响图，以评估与每个诊断测试相关的时间和金钱成本，并基于职业风险定义最佳协议策略。结果肌肉骨骼和眼科疾病被确定为VDT使用者中最常见的疾病。贝叶斯网络推断出年龄，睡眠质量，活动水平，吸烟和饮酒是危险因素。血液计数是最昂贵的检查（5.23美元/每位员工），第二贵重的时间检查（4分钟/每位员工），但它是诊断性检查，对员工做出工作能力的医疗决定影响不大工作。结论当前针对VDT用户的职业健康监视协议可能导致支出比必要的多54％。对于许多雇员和雇主来说，出于职业健康监控目的而未能执行广泛的医学检查被主观地视为对健康的威胁。需要提高对不同卫生领域的适当作用的认识，以便在更大的灵活性的基础上优化诊断效率。23美元/员工）和时间上第二昂贵的测试（4分钟/员工），但它是诊断测试，对员工决定工作能力的医疗决策影响不大。结论当前针对VDT用户的职业健康监视协议可能导致支出比必要的多54％。对于许多雇员和雇主来说，出于职业健康监控目的而未能执行广泛的医学检查被主观地视为对健康的威胁。需要提高对不同卫生领域的适当作用的认识，以便在更大的灵活性的基础上优化诊断效率。23美元/员工）和时间上第二昂贵的测试（4分钟/员工），但它是诊断测试，对员工决定工作能力的医疗决策影响不大。结论当前针对VDT用户的职业健康监视协议可能导致支出比必要的多54％。对于许多雇员和雇主来说，出于职业健康监控目的而未能执行广泛的医学检查被主观地视为对健康的威胁。需要提高对不同卫生领域的适当作用的认识，以便在更大的灵活性的基础上优化诊断效率。履行职责的能力。结论当前针对VDT用户的职业健康监视协议可能导致支出比必要的多54％。对于许多雇员和雇主来说，出于职业健康监控目的而未能执行广泛的医学检查被主观地视为对健康的威胁。需要提高对不同卫生领域的适当作用的认识，以便在更大的灵活性的基础上优化诊断效率。履行职责的能力。结论当前针对VDT用户的职业健康监视协议可能导致支出比必要的多54％。对于许多雇员和雇主来说，出于职业健康监控目的而未能执行广泛的医学检查被主观地视为对健康的威胁。需要提高对不同卫生领域的适当作用的认识，以便在更大的灵活性的基础上优化诊断效率。
