Pressure ulcer is largely avoidable, but its prevalence rate increased more than 80% in a 13 years study. Nurses have a great position to advance best practices towards the prevention of pressure ulcers. Therefore they should be knowledgeable of the signs and symptoms of pressure ulcers, and preventive strategies to reduce its incidence, but there is limited evidence on nurses' knowledge and its associated factors to prevent pressure ulcers in Ethiopia
A hospital-based cross-sectional study was conducted from March 25 - April 23/ 2018. A total of 356 nurses were selected by stratification with a simple random sampling technique. Pretested structured questionnaire with closed and open-ended questions was used to collect data. Frequency distribution and percentage were computed to describe each variable. Bivariate and multivariable logistic regression with a 95% confidence interval was also carried out to see the effect of each independent variable on the dependent variable and declared statistically significant association with < 0.05.
The mean knowledge score of nurses was 25.22 out of 41 item questions. Fifty-two point 5 % of nurses score above the mean. Males [AOR = 0.44, 95% CI (0.26-0.73)], working a maximum of eight hours [AOR = 3.57, 95% CI (1.48-8.61), not having training [(AOR = 2.31, 95% CI (1.14-4.61)], Low salary [AOR = 3.47, 95% CI (1.03-11.67)] were significantly associated with inadequate knowledge.
Generally a nurse's knowledge of pressure ulcers was inadequate. Being female, working less than or equal to eight hours, not having the training and low working salary are contributors to a low level of knowledge for pressure ulcers.
压疮在很大程度上是可以避免的，但在一项为期13年的研究中，其患病率增长了80%以上。护士在推进预防压疮的最佳实践方面具有重要地位。因此，他们应该了解压疮的体征和症状以及降低其发生率的预防策略，但在埃塞俄比亚，关于护士预防压疮的知识及其相关因素的证据有限。
于2018年3月25日至4月23日进行了一项基于医院的横断面研究。采用分层简单随机抽样技术共选取356名护士。使用预先测试的包含封闭式和开放式问题的结构化问卷收集数据。计算频率分布和百分比以描述每个变量。还进行了具有95%置信区间的双变量和多变量逻辑回归，以观察每个自变量对因变量的影响，并宣布在<0.05时具有统计学意义的关联。
在41项问题中，护士的平均知识得分为25.22分。52.5%的护士得分高于平均分。男性[AOR = 0.44，95% CI（0.26 - 0.73）]、工作时长最多为8小时[AOR = 3.57，95% CI（1.48 - 8.61）]、未接受培训[(AOR = 2.31，95% CI（1.14 - 4.61）]、低工资[AOR = 3.47，95% CI（1.03 - 11.67）]与知识不足显著相关。
总体而言，护士对压疮的知识不足。女性、工作时长小于或等于8小时、未接受培训以及低工资是导致压疮知识水平较低的因素。
