Objective.评估成人经药物治疗的关节炎和其他风湿性疾病（AORC）的总体患病率、特定经药物治疗的疾病的患病率以及门诊医疗保健系统中这些疾病的总体年就诊次数。我们使用2001-2005年全国门诊医疗调查和2001-2005年全国医院门诊医疗调查的数据来估计国际疾病分类第九次修订版的年度门诊医疗服务，临床修改代码被认为代表AORC。使用每例患者每种疾病的既往年度就诊次数数据，我们将就诊估计值转换为年龄≥ 18岁且接受药物治疗的AORC成人总体和特定疾病的患病率估计值。接受药物治疗的AORC成人的总体患病率估计值为29，150，000例成人（95%置信区间[95% CI] 26，473，000 - 31，826，000），门诊就诊次数为77，887，300次（95% CI 71，266，000 - 84，508，000）。前5位最常见的疾病是骨关节炎和相关疾病、未特指的关节疾病、外周肌腱端病、未特指的关节病和其他滑膜、肌腱或囊疾病。我们的方法的优点是，它使用现有的，而不是昂贵的新的调查，以跟踪整体的医学治疗AORC的患病率和跟踪的患病率难以衡量的具体条件。这些估计数是以数据为基础的，范围是全国。更相关的是，他们更好地估计了AORC影响门诊医疗保健系统的人数。
Objective. To estimate the overall prevalence of medically-treated arthritis and other rheumatic conditions (AORC) for adults, the prevalence of specific medically-treated conditions, and the overall annual number of visits for these conditions in the ambulatory health care system.Methods. We used data from the 2001-2005 National Ambulatory Medical Care Survey and 2001-2005 National Hospital Ambulatory Medical Care Survey to estimate annual ambulatory health care visits for the International Classification of Diseases, Ninth Revision, Clinical Modification codes thought to represent AORC. Using data on the number of prior annual visits per patient per condition, we converted the visit estimates into prevalence estimates of adults age >= 18 years with medically-treated AORC overall and for specific conditions.Results. The overall prevalence estimate of adults with medically-treated AORC was 29,150,000 adults (95% confidence interval [95% CI] 26,473,000-31,826,000) and accounted for 77,887,300 ambulatory care visits (95% CI 71,266,000-84,508,000). The top 5 most prevalent conditions were osteoarthritis and allied disorders, unspecified joint disorders, peripheral enthesopathies, unspecified arthropathies, and other disorders of synovium, tendon, or bursa.Conclusion. The advantage of our approach is that it uses existing rather than expensive new surveys for tracking the prevalence of medically-treated AORC overall and tracking the prevalence of difficult to measure specific conditions. The estimates are data based and national in scope. More relevantly, they better estimate the numbers of persons whose AORC impacts on the ambulatory health care system.
