This paper was to assess the risk for cross infection caused by blood-contaminated tampon after dental extraction and whether this risk was reduced after relevant education towards both dentists and patients.
From December 2014 to April 2015, a survey was conducted in dentists and patients randomly before and after relevant education. The questionnaire is being revised for this survey based on learning from Chatzoudi and Franklin' survey. This survey was approved by the institutional review board, and all participants were voluntary and all responses were anonymous.
Only 2.82 % of dentists provided patients with the postoperative-advices regarding how to dispose of blood-contaminated tampon at the first time and 47.10 % at the second time (P < 0.01). Only 1.41 % of dentists given special postoperative-advices regarding disposal of tampon to patients with blood-transmitted diseases at the first time and 24.64 % at the second time (P < 0.01). Before education, most patients were lack of nosocomial infection knowledge. After education, 22.4 % of patients threw the blood-contaminated tampon away in a proper way (P < 0.01). 66.67 % of them washed hands immediately and thoroughly after they touched the tampon (P < 0.05), 92.71 % knew the blood-contaminated tampon can cause cross-infection (P < 0.01), and 80.21 % knew how to dispose of the blood-contaminated tampon correctly (P < 0.01).
The high risk of cross infection caused by blood-contaminated tampon is evident, and a series of measures is proposed to control it. There is a need to improve both dentists' and patients' awareness, enhance the education of doctors and perfect the policies and guidelines.
本文旨在评估拔牙后血液污染棉球引起交叉感染的风险，以及对牙医和患者进行相关教育后该风险是否降低。
2014年12月至2015年4月，在相关教育前后对牙医和患者进行随机调查。本次调查的问卷是在借鉴Chatzoudi和Franklin的调查基础上进行修订的。本调查经机构审查委员会批准，所有参与者均为自愿，所有回答均为匿名。
只有2.82%的牙医在首次时向患者提供了关于如何处理血液污染棉球的术后建议，第二次时为47.10%（P<0.01）。只有1.41%的牙医在首次时向患有血液传播疾病的患者提供了关于处理棉球的特殊术后建议，第二次时为24.64%（P<0.01）。教育前，大多数患者缺乏医院感染知识。教育后，22.4%的患者以正确方式扔掉了血液污染的棉球（P<0.01）。其中66.67%的人在接触棉球后立即彻底洗手（P<0.05），92.71%的人知道血液污染的棉球会导致交叉感染（P<0.01），80.21%的人知道如何正确处理血液污染的棉球（P<0.01）。
血液污染棉球引起交叉感染的高风险显而易见，为此提出了一系列控制措施。有必要提高牙医和患者的意识，加强医生教育，完善政策和指南。
