在美国，骨质疏松症和骨折的全国成本估计是基于不同的医疗数据集或选定的商业保险索赔。我们试图通过随机的老年人人群样本来描述骨质疏松症的患病率和成本。医疗费用的横断面估计是利用2002年医疗保险现行受益人调查（MCBS）的数据做出的。MCBS将健康访谈与来自所有付款人的索赔信息结合起来，对12700名医疗保险受助人进行随机抽样。定义了三个年龄在65岁或以上的队列：1)2002年经历骨折相关索赔的患者；2)骨质疏松症或髋部骨折的诊断、用药或自我报告患者；3)非病例对照。使用多元回归将患者索赔的总费用与对照组进行比较。2002年，在3020万老年医疗保险受益人中，160万（5%）当年接受了骨折治疗，另外720万（24%）患有骨质疏松症而没有骨折。估计骨折对每年医疗费用的平均影响为8600美元（95%可信区间：6400至10800美元），这意味着美国的医疗费用为140亿美元（100至170亿美元）。一半的非骨折性骨质疏松症患者接受了药物治疗，平均每个患者500美元，全国20亿美元。根据2002年全国人口为基础的样本，美国老年人骨质疏松和骨折的年度成本估计为160亿美元。这一数额证实了以前根据不同方法所作的估计。预计到2008年，全国骨质疏松和骨折的费用为220亿美元。
National cost estimates of osteoporosis and fractures in the U.S. have been based on diverse sets of provider data or selected commercial insurance claims. We sought to characterize prevalence and costs for osteoporosis using a random population-based sample of older adults. A cross-sectional estimate of medical cost was made with 2002 data from the Medicare Current Beneficiary Survey (MCBS). MCBS combines health interviews with claims information from all payers to profile a random sample of 12,700 Medicare recipients. Three cohorts aged 65 or over were defined: 1) patients experiencing a fracture-related claim in 2002; 2) patients with a diagnosis, medication, or self-report for osteoporosis or past hip fracture; and 3) non-case controls. The total cost of patient claims was compared to that of controls using multivariate regression. Of 30.2 million elderly Medicare recipients in 2002, 1.6 million (5%) were treated for a fracture that year and an additional 7.2 million (24%) have osteoporosis without a fracture. The estimated mean impact of fractures on annual medical cost was $8600 (95%CI: $6400 to $10,800), implying a U.S. cost of $14 billion ($10 to $17 billion). Half of the non-fracture osteoporosis patients received drug treatment, averaging $500 per treated patient, or $2 billion nationwide. The annual cost of osteoporosis and fractures in the U.S. elderly was estimated at $16 billion, using a national 2002 population-based sample. This amount corroborates previous estimates based on substantially different methodologies. Projected to 2008, the national cost of osteoporosis and fractures was $22 billion.
