Background: Burnout, marked by emotional exhaustion and reduced clinical performance, may impair the effective application of noninvasive respiratory support (NIRS) and timely transition to invasive methods, potentially affecting patient outcomes. This study aims to identify the impact of burnout on the knowledge, attitudes, and practices (KAP) of healthcare professionals in the application of respiratory support, and further explore how other factors may influence these areas.

Method: A cross-sectional study was conducted from November 15, 2023, to December 14, 2023, at multiple hospitals in central China, involving key departments such as emergency, respiratory, cardiology, and critical care. Demographic information, alongside scores measuring KAP was gathered through the dissemination of questionnaires. Knowledge was assessed using a scoring system (range: 0-24), while attitude and practice were measured using 5-point Likert scales, with score ranges of 8-40 and 8-56, respectively. The Chinese version of the Maslach Burnout Inventory General Survey (MBI-GS) was used to assess occupational burnout.

Results: A total of 517 valid questionnaires were enrolled, including 284 (54.9%) nurses, and 269 (52%) had worked for less than 10 years. The median scores for knowledge, attitude, practice, and burnout were 20, 26, 38, and 40, respectively. Participants from private hospitals exhibited burnout scores higher than 50. Burnout was negatively correlated with both attitude (r = -0.289) and practice (r = -0.206). Multivariate logistic regression showed that practice, as the dependent variable, was independently associated with a knowledge score below 20 (OR = 0.441, 95% CI: [0.297, 0.657]), an attitude score below 26 (OR = 0.493, 95% CI: [0.335, 0.724]), and burnout scores below 40 (OR = 0.539, 95% CI: [0.364-0.796]) were independently associated with practice. Age above 40 years (OR = 0.470, 95% CI: [0.264, 0.837]), being a nurse (OR = 0.627, 95% CI: [0.424, 0.928]), and lack of recent training in respiratory support (OR = 0.590, 95% CI: [0.403, 0.866]) were also associated with lower practice scores.

Conclusions: Healthcare professionals had sufficient knowledge, positive attitudes, and proactive practices regarding the application of respiratory support. However, the impact of burnout must not be overlooked, even for those scoring below the threshold (50 points), as burnout can still significantly affect clinical performance. Healthcare institutions should prioritize continuous education and training programs focusing on respiratory support, especially for high stress environment professionals, to enhance clinical practice and patient outcomes.

背景： 工作倦怠，表现为情绪耗竭和临床表现下降，可能会影响非侵入性呼吸支持（NIRS）的有效应用以及及时转为侵入性方法的能力，从而影响患者的预后。本研究旨在识别工作倦怠对医疗保健专业人员在呼吸支持应用方面的知识、态度和实践(KAP)的影响，并进一步探索其他因素如何影响这些领域。

方法： 一项横断面研究于2023年11月15日至2023年12月14日期间在中国中部地区的多家医院进行，涉及急诊科、呼吸科、心血管科和重症监护等关键部门。通过分发问卷收集了人口统计学信息以及测量KAP的得分。知识通过评分系统（范围：0-24）评估，态度和实践则使用5点李克特量表衡量，得分为8-40和8-56之间。采用中文版马斯拉赫职业倦怠通用调查问卷(MBI-GS)来评估职业倦怠。

结果： 共收集了517份有效问卷，包括284名（占总数的54.9%）护士和269名（占总数的52%）工作年限少于10年的医护人员。知识、态度、实践以及职业倦怠的中位得分分别为20分、26分、38分和40分。来自私立医院的参与者的职业倦怠得分高于50分。职业倦怠与态度（r = -0.289）和实践（r = -0.206）呈负相关。多变量逻辑回归显示，作为自变量的实践独立关联的知识分数低于20（OR = 0.441, 95% CI: [0.297, 0.657]），态度分数低于26（OR = 0.493, 95% CI: [0.335, 0.724]）以及职业倦怠分数低于40（OR = 0.539, 95% CI: [0.364-0.796]）。年龄超过40岁（OR = 0.470, 95% CI: [0.264, 0.837]）、是护士（OR = 0.627, 95% CI: [0.424, 0.928]）以及缺乏最近的呼吸支持培训（OR = 0.590, 95% CI: [0.403, 0.866]）也都与较低的实践得分相关。

结论： 医疗保健专业人员在应用呼吸支持方面具备充足的知识、积极的态度和主动的实践。然而，不应忽视工作倦怠的影响，即使在评分低于阈值（50分）的情况下，因为职业倦怠仍然可以显著影响临床表现。医疗卫生机构应优先考虑以呼吸支持为重点的持续教育和培训项目，特别是针对高压力环境下的专业人员，从而提升临床实践和患者预后。
