摘要目的:调查中国儿科医务人员对脉搏血氧饱和度监测的知识、态度和行为(简称知信行)，并分析其影响因素。方法:采用自行设计的问卷，在2022年3月11日至14日对来自中国31个省、自治区、直辖市的11 849例儿科医务人员进行线上调查。采用 Logistic回归分析儿科医务人员脉搏血氧饱和度监测知信行的主要影响因素。 结果:儿科医务人员脉搏血氧饱和度监测知识、态度、行为总得分分别为(5.57±0.96)分、(11.24±1.25)分和(11.19±4.54)分，得分率分别为69.61%、74.95%和55.99%。 Logistic回归分析显示，儿科医务人员的年龄、从业年限、所在地区和所在单位是否配置脉搏血氧仪是知识水平的主要影响因素(均 P<0.05)；知识水平、性别、学历、从业年限、所在地区、所在医院级别和所在单位是否配置脉搏血氧仪是态度水平的主要影响因素(均 P<0.05)；知识水平、性别、年龄和所在单位是否配置脉搏血氧仪是行为水平的主要影响因素(均 P<0.05)。 结论:中国儿科医务人员对脉搏血氧饱和度监测的知识和态度水平有待进一步提高，脉搏血氧仪的使用存在明显不足。亟须制定相关政策/指南，加强教育培训，提高知信度，增加脉搏血氧仪的配置，普及推广脉搏血氧饱和度监测在临床实践中的应用。

abstractsObjective:To investigate the knowledge, attitudes, and practices (KAP) of pulse oximetry among pediatric healthcare providers in China and analyze the factor influencing the KAP.Methods:A self-developed questionnaire was used for an online research on the KAP of 11 849 pediatric healthcare providers from 31 provinces, autonomous regions, and municipalities of China from March 11 to 14, 2022.The factors influencing the KAP of pulse oximetry among pediatric healthcare providers were examined by Logistic regression. Results:The scores of KAP, of pulse oximetry were 5.57±0.96, 11.24±1.25 and 11.19±4.54, respectively.The corresponding scoring rates were 69.61%, 74.95%, and 55.99%, respectively. Logistic regression results showed that the gender and working years of pediatric healthcare providers, the region they were located, and whether their medical institution was equipped with pulse oximeters were the main factors affecting the knowledge score (all P<0.05). Main factors influencing the attitude score of pediatric healthcare providers included their knowledge score, gender, educational background, working years, region, medical institution level, and whether the medical institution was equipped with pulse oximeters (all P<0.05). For the practice score, the main influencing factors were the knowledge score, gender, age, and whether the medi-cal institution was equipped with pulse oximeters (all P<0.05). Conclusions:Chinese pediatric healthcare providers need to further improve their knowledge about and attitudes towards pulse oximetry.Pulse oximeters are evidently under-used.It is urgent to formulate policies or guidelines, strengthen education and training, improve knowledge and attitudes, equip more institutions with pulse oximeters, and popularize their application in medical institutions.
