Moistening of surgical instruments affects the quality of instrument cleaning, thereby affecting the degree of cross-contamination and in-hospital infection among patients. Surgical instruments should be kept moist immediately after use in order to avoid concentrations of contamination remaining on surgical instrument surfaces. Implementation and pass rates of surgical instrument moistening have been rarely studied. We aimed to investigate the factors affecting implementation and pass rates of surgical instrument moistening.
A cross-sectional study was conducted to investigate surgical instrument moistening procedures within 22 clinical departments of the West China Second University Hospital, Sichuan University over 122 days between September and December 2019. We collected data from departmental staff using an interviewer-administrated questionnaire. Data about implementation and pass rates of surgical instrument moistening was analyzed in SPSS20.0.
Implementation and pass rates of surgical instrument moistening were 57.25% and 31.98%, respectively. Factor analysis showed that implementation rates of moistening were affected by instrument structure (X = 143.670; P = 0.001), the number of instruments inside the pack (X = 140.135; P = 0.001), and the person responsible for keeping surgical instruments moist (X = 8.052; P = 0.005). Correlation analysis showed that instrument structure and the number of instruments inside the pack were negatively correlated with implementation rates of moistening. The more complex the structure and the greater the number of the instruments inside the pack, the lower implementation rates of moistening.
Implementation and pass rates of surgical instrument moistening were low, and failed to meet the central sterile supply department applicable industrial standard, hence the potential risk of hospital-acquired infection was considerable. Staff that manipulate reusable surgical instruments should be trained to properly moisten the instruments and institutional protocols should be established to ensure standardization and respect of guidelines.
手术器械的保湿情况会影响器械清洗质量，进而影响患者之间的交叉污染和院内感染程度。手术器械使用后应立即保湿，以避免器械表面残留污染物浓度增加。手术器械保湿的实施率和合格率很少被研究。我们旨在调查影响手术器械保湿实施率和合格率的因素。
2019 年 9 月至 12 月，我们采用横断面研究方法，对四川大学华西第二医院 22 个临床科室的手术器械保湿情况进行了为期 122 天的调查。我们使用访谈式问卷收集科室工作人员的数据。使用 SPSS20.0 对手术器械保湿的实施率和合格率进行数据分析。
手术器械保湿的实施率和合格率分别为 57.25%和 31.98%。因子分析显示，保湿实施率受器械结构（X=143.670，P=0.001）、包装内器械数量（X=140.135，P=0.001）和负责保湿手术器械的人员（X=8.052，P=0.005）的影响。相关分析显示，器械结构和包装内器械数量与保湿实施率呈负相关。器械结构越复杂，包装内器械数量越多，保湿实施率越低。
手术器械保湿的实施率和合格率均较低，未达到中心供应室适用的工业标准，因此存在医院获得性感染的风险较大。应培训操作可重复使用手术器械的工作人员，正确保湿器械，并制定机构规程，以确保标准化和遵循指南。
