We estimated the incidence of admissions related to interstitial cystitis in Japan using a national administrative claims database, the Diagnosis Procedure Combination database, which included information for 53.6% of urological training hospitals certified by the Japanese Urological Association. "Admissions related to interstitial cystitis" was defined as those cases whose ICD-10 code for the main reason for admission was N301 (interstitial cystitis) between 2007 and 2009. Among 8.42 million inpatient cases, 784 female and 212 male patients with interstitial cystitis were identified. The ratio of females to males was 3.69 and the median age was 67 years (range 5-92 years). The admission incidence (per 100 000 person-years) in females and males was estimated to be 1.35 (95% confidence interval 1.25-1.46) and 0.37 (0.31-0.42), respectively. This incidence is low compared with other reports. Possible reasons for this finding include racial difference, clinical examination methods, lack of outpatient data and poor health-care coverage of interstitial cystitis.
我们使用全国行政索赔数据库——诊断程序组合数据库，来估算日本间质性膀胱炎住院治疗的发病率，该数据库包含了日本泌尿科协会认证的 53.6%泌尿科培训医院的信息。“与间质性膀胱炎相关的住院治疗”被定义为 2007 年至 2009 年间，因主要入院原因 ICD-10 编码为 N301（间质性膀胱炎）的病例。在 842 万例住院病例中，共发现 784 名女性和 212 名男性间质性膀胱炎患者。女性与男性的比例为 3.69，中位年龄为 67 岁（范围为 5-92 岁）。女性和男性的住院治疗发病率（每 10 万人年）估计分别为 1.35（95%置信区间 1.25-1.46）和 0.37（0.31-0.42）。与其他报告相比，这一发病率较低。造成这种发现的可能原因包括种族差异、临床检查方法、缺乏门诊数据以及间质性膀胱炎的医疗保健覆盖范围不佳。
