Home medical care (HMC) is advancing not only in Japan but also throughout the world. In Japan, HMC waste is legally classified as municipal waste. Nevertheless, some municipalities do not collect some or all the HMC waste because of fear of infection. Therefore, this study was conducted to clarify the following two issues: First, have the municipalities made progress in collecting and appropriate disposal of HMC waste in the past 13 years? Second, is there a difference between a large city and a small city in terms of appropriate disposal progress? A total of 687 municipalities published the treatment of HMC waste. Currently, 42 municipalities collected all HMC waste. 236 municipalities were collecting HMC waste except for self-injection needle. 117 municipalities were collecting HMC waste except for self-injection needle and Syringe. The collection status of HMC waste was better in cities with high population than in cities with low population. HMC waste collection status was progressed over 13 years. However, more than 60% of the municipality staff stated that they could not avoid being anxious about infection caused by HMC waste. We suggest that providing HMC waste education to the municipalities wherein these efforts have not yet progressed is important.

家庭医疗保健（HMC）不仅在日本而且在全世界都在发展。在日本，HMC废物在法律上被归类为城市废物。但是，由于担心受到感染，一些市政当局并未收集部分或全部HMC废物。因此，进行这项研究以澄清以下两个问题：首先，在过去的13年中，市政当局在收集和适当处置HMC废物方面是否取得了进展？第二，就适当的处置进度而言，大城市和小城市之间是否有区别？共有687个城市发布了HMC废物处理方法。目前，有42个城市收集了所有HMC废物。除自动注射针头外，有236个城市正在收集HMC废物。除自动注射针头和注射器外，有117个城市正在收集HMC废物。高人口城市的HMC废物收集状况要好于低人口城市。HMC废物收集状态已有13年的历史了。但是，超过60％的市政工作人员表示，他们无法避免对HMC废物引起的感染感到焦虑。我们建议向尚未开展这些工作的市政当局提供HMC废物教育非常重要。
