【摘要】目的探讨物联网闭环管理在居家腹膜透析患者医疗废物处置中的应用价值。方法将119 例居家腹膜透析患者随机分为对照组(61 例)和研究组(58 例)，对照组给予常规的教育和指导，研究组在对照组的基础上应用物联网闭环管理进行干预，采用自设问卷调查的方法了解腹膜透析患者对医疗废物的处置情况，比较2 组患者干预前后医疗废物处置情况的差异。结果研究组的医疗废物规范处置率从干预前的3.4%上升至干预后的91.4%，差异具有统计学意义(χ2=89.327,P＜0.001)，干预后研究组对医疗废物的规范处置率较对照组提高，差异具有统计学意义(χ2=82.338,P＜0.001)；研究组的腹膜透析废液袋回收率从干预前的3.47%上升至干预后的91.37%，差异具有统计学意义(χ2=86.726,P＜0.001)，干预后研究组的腹膜透析废液袋回收率较对照组提高，差异具有统计学意义(χ2=76.842,P＜0.001)。结论物联网闭环管理能规范居家腹膜透析患者的医疗废物处置行为，具有重要的应用价值，是未来居家腹
膜透析医疗废物管理的发展趋势。
【Abstract】Objective To explore the application value of closed loop management of Internet of Things in disposal of medical waste of peritoneal dialysis (PD) patients at home. Methods A total of 119 PD patients at home were randomly divided into control group (n=61) and intervention group (n=58). Conventional education and guidance were given to the control group, and closed loop management of Internet of Things in addition to the conventional education and guidance were given to the intervention group. The self-designed questionnaire was used to understand the disposal of medical waste by PD patients. The disposal of medical waste before and after the intervention was compared between the two groups. Results In the intervention group, the rate of standardized disposal of medical waste increased from 3.4% before the intervention to 91.4% after the intervention (χ2= 89.327, P<0.001), and the rate of standardized disposal of medical waste was significantly higher in the intervention group than in the control group (χ2=82.338, P<0.001). The recovery rate of PD waste liquid bags in the intervention group increased from 3.47% before intervention to 91.37% after intervention (χ2=86.726, P<0.001). The recovery rate of PD waste liquid bags was significantly higher in the intervention group than in the control group (χ2=76.842, P<0.001). Conclusion The closed loop management of Internet of Things can standardize the behavior of disposal of medical waste in PD patients at home. This method
is valuable for practical use, and is the recent trend of medical waste management for PD at home.
