To estimate the prevalence and costs of respiratory illness for workers in coal mining, compared with other US industries.
Using 5 years of insurance claims data for an annual average of 96,240 adult males, we model the probability and costs of respiratory illness as a function of workers' industry and other factors.
Controlling for nonindustry factors, workers in coal mining had significantly higher rates of respiratory illness claims (by 2.1% to 3.3% points) compared with other mining, agriculture, construction, and manufacturing. For coal mining workers with respiratory illness, annual medical care costs for these claims were also significantly higher (by $111 to $289). Surprisingly, drug costs were mostly lower (by $17 to $268).
Our findings underscore the continued importance and potential cost effectiveness of measures to protect miners from harmful occupational exposures, particularly to coal dust.
与其他美国行业相比，估算矿工呼吸疾病的患病率和成本。
利用 5 年的保险索赔数据，对每年平均 96240 名成年男性进行分析，我们将呼吸疾病的概率和成本作为工人行业和其他因素的函数进行建模。
控制非行业因素后，与其他矿业、农业、建筑和制造业相比，煤矿工人的呼吸疾病索赔率显著更高（高出 2.1%至 3.3%）。对于患有呼吸疾病的煤矿工人，这些索赔的年医疗费用也明显更高（高出 111 至 289 美元）。令人惊讶的是，药物成本大多较低（低 17 至 268 美元）。
我们的研究结果强调了继续采取措施保护矿工免受有害职业暴露的重要性和潜在的成本效益，特别是针对煤矿粉尘。
