To estimate indirect costs associated with inflammatory bowel disease (IBD).
This was a retrospective study using 1996 to 2006 US Medical Expenditure Panel Survey data. Employed individuals were aged 18 to 64 years. A two-part model estimated the probability of time lost from work because of illness and the annual number of workdays missed.
A total of 71.5% (143/200) and 58.2% (52,257/89,846) of individuals with and without IBD, respectively, missed time from work because of illness (P = 0.0001). Among individuals who missed work, those with IBD missed more workdays annually than those without IBD ((Equation is included in full-text article.)= 13.38, 9.89, respectively; P = 0.044). Incremental per capita cost in annual lost workdays between those with and without IBD was $783. National indirect IBD-related costs were $249 million annually.
Individuals with IBD have higher probabilities of missing time from work and missing workdays than those without IBD.
评估与炎症性肠病（IBD）相关的间接成本。
这是一项回顾性研究，使用了 1996 年至 2006 年美国医疗支出面板调查数据。18 至 64 岁的在职人员参与了研究。采用两部分模型估计因疾病而损失工作时间的概率和每年错过的工作日数。
分别有 71.5%（143/200）和 58.2%（52,257/89,846）的 IBD 患者和非 IBD 患者因病缺勤（P = 0.0001）。在因病缺勤的人群中，IBD 患者每年缺勤的天数多于非 IBD 患者（(Equation is included in full-text article.)= 13.38, 9.89，分别为；P = 0.044）。IBD 患者与非 IBD 患者之间每年因失去工作而产生的人均增量成本为 783 美元。每年与 IBD 相关的国家间接成本为 2.49 亿美元。
与非 IBD 患者相比，IBD 患者更有可能缺勤和旷工。
