Uses of computer-generated maps in occupational hazard and mortality surveillance.
描述了美国国家职业安全与健康研究所使用计算机生成地图的五种方式，包括展示工作场所危害的空间位置和年龄标准化死亡率，以生成职业健康监测线索。
The purpose of the present paper was to describe five ways in which computer-generated maps for 3,073 United States political subdivisions (counties) are being used as a part of the National Institute for Occupational Safety and Health surveillance system. Four maps show the approximate spatial location of potential workplace hazards in terms of (i) worksites, (ii) estimates of the proportion of workers at risk for US counties, and (iv) counties within a selected state. A fifth map shows age-standardized county-level mortality for a cause of death associated with an occupational risk. These five types of maps represent first efforts to present and disseminate information in an effective format and to generate occupational health surveillance leads that may warrant further research.
