Abstract：
BACKGROUND: The PiccPed® health application was developed to support clinical decision-making in peripherally inserted central catheter (PICC) management. We aimed to evaluate its impact on nurses\' knowledge regarding the prevention of PICC-associated adverse events in pediatrics and neonatology.
METHODS: A quasi-experimental, pre-post intervention study, was conducted with a dependent/paired sample of pediatric and neonatal nurses from two tertiary hospitals in South Brazil. Data were collected from October 2022 to January 2023 across three phases: pre-, intervention (use of the PiccPed®) and post-test. Study outcomes were a knowledge test (15 questions) of evidence-based PICC maintenance procedures, and PiccPed® app time spent and screens used.
RESULTS: A total of 56 nurses completed the study. The post-test mean score was significantly higher (12/15; standard deviation (SD) 1.9) in comparison with the pre-test (mean 9/15; SD 2.2). The change in scores was significantly higher for nurses without postgraduate qualifications, in comparison to those with (Mean Difference 1.26; p = 0.039). Each minute using the app resulted in a significant increase of 0.04 points (95% confidence interval 0.01-0.08; p = 0.014) on the mean post-test score (10.94 points).
CONCLUSIONS: The research demonstrated that PiccPed® enhances nurses\' learning regarding the prevention of adverse events associated with PICC maintenance in pediatrics and neonatology.
CONCLUSIONS: The app can be safely and effectively used for training and continuing education of nurses who care for children and neonates with PICCs.

摘要：
背景：开发PiccPed®健康应用程序以支持外周置入中心静脉导管（PICC）管理中的临床决策。我们旨在评估其对预防儿科和新生儿科PICC相关不良事件的护士知识的影响。
方法：准实验，干预前研究,与来自巴西南部两家三级医院的儿科和新生儿护士的依赖/配对样本进行。数据收集时间为2022年10月至2023年1月，分为三个阶段：预，干预(使用PiccPed®)和后期测试。研究结果是一项基于证据的PICC维护程序的知识测试(15个问题)，和PiccPed®应用程序花费的时间和使用的屏幕。
结果：共有56名护士完成了这项研究。与预测试（平均值9/15；SD2.2）相比，测试后的平均值显着更高（12/15；标准偏差（SD）1.9）。没有研究生学历的护士分数变化明显较高,与(平均差1.26；p=0.039)相比。使用app的每分钟导致平均测试后评分（10.94分）上0.04分（95％置信区间0.01-0.08；p=0.014）的显着增加。
结论：研究表明，PiccPed®提高了护士对预防儿科和新生儿科PICC维护相关不良事件的认识。
结论：该应用程序可以安全有效地用于护理患有PICC的儿童和新生儿的护士的培训和继续教育。
