Abstract

Objectives

This study aimed to characterize the epidemiology of scabies and its outbreaks in Japanese households, residential care facilities (RCFs), and hospitals using claims data.

Methods

This descriptive epidemiological study was conducted using claims data from eight municipalities in Japan. Scabies cases were identified using a combination of recorded diagnoses and administered medications. The study period was from April 2015 to March 2019. Outbreaks were defined as ≥2 cases of scabies occurring within a calendar month at a single household, RCF, or hospital.

Results

We identified 857 scabies cases for analysis. The annual prevalence of scabies ranged from 40 to 67 per 100,000 beneficiaries. The annual attack rate of scabies was found to be highest in RCFs (21 per 1000 RCFs), followed by hospitals (11 per 1000 hospitals) and households (0.25 per 1000 households). The annual outbreak attack rate was also highest in RCFs (4.0 per 1000 RCFs), followed by hospitals (1.6 per 1000 hospitals) and household (0.027 per household). The patterns of outbreaks varied widely among the RCFs.

Conclusions

The study showcases the potential of claims data for detecting infectious disease outbreaks, which could provide valuable insight for the future management and prevention of scabies. Infection control of scabies in RCFs is crucial in aging societies.

利用索赔数据调查日本家庭、寄宿护理机构和医院的疥疮流行病学和爆发情况：LIFE 研究

目的本研究旨在利用理赔数据描述疥疮的流行病学特征及其在日本家庭、寄宿护理设施 (RCF) 和医院中的爆发情况。方法本描述性流行病学研究利用日本 8 个城市的理赔数据进行。疥疮病例是通过记录的诊断和用药组合确定的。研究时间为 2015 年 4 月至 2019 年 3 月。疥疮暴发的定义是在一个日历月内，单个家庭、RCF 或医院发生的疥疮病例≥2 例。每 10 万名受益人中，疥疮的年发病率从 40 例到 67 例不等。疥疮的年发病率在社区保健中心最高（每 1000 个社区保健中心中有 21 例），其次是医院（每 1000 个医院中有 11 例）和家庭（每 1000 个家庭中有 0.25 例）。每年疫情爆发率最高的也是垃圾收集设施（每 1000 个垃圾收集设施中有 4.0 例），其次是医院（每 1000 个医院中有 1.6 例）和家庭（每 1000 个家庭中有 0.027 例）。结论这项研究展示了索偿数据在检测传染病爆发方面的潜力，可为今后疥疮的管理和预防提供有价值的见解。在老龄化社会中，垃圾收集设施中的疥疮感染控制至关重要。
