The accuracy of a stroke registration program in Iwate prefecture was greatly affected by cooperation from medical facilities and doctors in the field. The number of registered cases from noncore hospitals was less, but the accuracy of registration was unknown. This report presents the impact and effectivity of an inventory survey of the stroke registry.
Details of subjects living in coastal and northern regions of Iwate Prefecture who developed a cerebrovascular attack between 2012 and 2014 were obtained from the Iwate Stroke Registry through an inventory survey. Annual incidence rate from core hospitals and noncore hospitals were compared. To evaluate factors registered from noncore hospitals, multivariate analyses were performed for sex, age, living area, type of stroke, and past history of cerebrovascular diseases.
Annual crude incidence rate for 100,000 residual populations were 428.8 in men and 351.2 in women from core hospitals and 38.5 in men and 43.7 in women from noncore hospitals. Ratios of noncore hospitals against all the hospitals were 8.3% for men and 11.1% for women. Multivariate analyses for age, ischemic type of stroke, past history of cerebrovascular diseases, and living in areas without a core hospital were significant; however, sex was not a significant factor.
The inventory survey of the stroke registry program in the Iwate prefecture was useful to prevent missing data of stroke cases from noncore hospitals, including patients who are elderly, with ischemic stroke onset, with a past history of stroke, or living in areas without core hospitals.
岩手县卒中登记项目的准确性在很大程度上受到当地医疗机构和医生合作情况的影响。非核心医院登记的病例数量较少，但登记的准确性尚不清楚。本报告介绍了卒中登记库存调查的影响和效果。
通过库存调查从岩手县卒中登记处获取2012年至2014年间在岩手县沿海和北部地区发生脑血管疾病发作的患者详细信息。比较核心医院和非核心医院的年发病率。为评估非核心医院登记的因素，对性别、年龄、居住地区、卒中类型和脑血管疾病既往史进行多因素分析。
核心医院每10万常住人口的年粗发病率男性为428.8，女性为351.2；非核心医院男性为38.5，女性为43.7。非核心医院占所有医院的比例男性为8.3%，女性为11.1%。年龄、缺血性卒中类型、脑血管疾病既往史以及居住在无核心医院地区的多因素分析具有统计学意义；然而，性别不是一个显著因素。
岩手县卒中登记项目的库存调查有助于防止非核心医院卒中病例数据的遗漏，包括老年患者、缺血性卒中发病患者、有卒中既往史患者或居住在无核心医院地区的患者。
