Ventilator-associated pneumonia (VAP) is the most common nosocomial infection in patients requiring mechanical ventilation in intensive care units (ICUs). VAP is associated with delayed extubation, prolonged hospital stays, increased healthcare costs and mortality rates. The aims of this study to evaluate the level of knowledge for the prevention of VAP among healthcare workers (HCWs) in ICUs and to assess their knowledge in relation to their socio-demographic characteristics.
A descriptive, cross-sectional design was conducted to assess HCWs' knowledge of the guidelines for prevention of VAP in the ICUs of public and private hospitals in Hodeida city, Yemen. Around 140 self-administered multiple-choice questionnaires were distributed between April and July 2017.
A total of 120 (85.6%) HCWs completed questionnaire were obtained (20 physicians, 20 anesthesia technicians and 80 nurses) in this study. The total mean score of the HCWs' knowledge was low (41 ± 18). A statistically significant difference was found in the HCWs' knowledge scores according to their specialties and gender. Anesthesia technicians had the highest knowledge score followed by physicians and nurses (52.2 ± 16.2, 45.6 ± 21.2 and 37.1 ± 16.9, respectively, p=0.002). Males had higher scores than females (Median [IQR] 4 [3-5] vs. 3 [2-4], p<0.001). Participants who received information about the prevention of VAP had better knowledge than those who did not (46.2 ± 17.7 vs. 36.8 ± 17.3, p=0.006).
HCWs had a low knowledge level of the guidelines for the prevention of VAP, which may affect their practice. HCWs' knowledge was affected by their previous received information that increases the necessity to provide them with regular in-service education and training programs.
呼吸机相关性肺炎（VAP）是重症监护病房（ICU）中需要机械通气的患者最常见的医院感染。VAP与拔管延迟、住院时间延长、医疗费用增加及死亡率上升相关。本研究旨在评估ICU医护人员（HCWs）对VAP预防知识的掌握程度，并根据其社会人口学特征评估他们的知识水平。
采用描述性横断面设计，评估也门荷台达市公立和私立医院ICU中HCWs对VAP预防指南的知识。2017年4月至7月期间发放了约140份自填式多项选择题问卷。
本研究共获得120名（85.6%）完成问卷的HCWs（20名医生、20名麻醉技师和80名护士）。HCWs知识的总平均分较低（41±18）。根据其专业和性别，HCWs的知识得分存在统计学显著差异。麻醉技师的知识得分最高，其次是医生和护士（分别为52.2±16.2、45.6±21.2和37.1±16.9，p=0.002）。男性得分高于女性（中位数[四分位间距]4[3-5]对3[2-4]，p<0.001）。接受过VAP预防信息的参与者比未接受过的参与者知识更好（46.2±17.7对36.8±17.3，p=0.006）。
HCWs对VAP预防指南的知识水平较低，这可能会影响他们的实践。HCWs的知识受到其先前接受信息的影响，这增加了为他们提供定期在职教育和培训项目的必要性。
