Nurses are members of multidisciplinary teams providing care to extracorporeal membrane oxygenation-supported patients (ECMO-SP). There are no valid and reliable measurements available to assess nursing activities in the care of ECMO-SP.
To develop and evaluate psychometric properties of a new 27-item nursing activities in the care of ECMO-SP scale.
A convenience sample was recruited of 76 registered nurses (mean age 41.3 ± 8.7; 71% female) in Israel. The nurses participated in an online survey with software Qualtrics, between March and June 2022. Content and construct validity, as well as internal consistency of the scale were evaluated. The participants also completed the perceived knowledge and skills in the treatment of ECMO-SP scale. The correlations between nursing activities in the care of ECMO-SP and ECMO knowledge were examined using Pearson's correlation.
Exploratory factor analysis extracted four factors, and seven items were excluded from the 27-item scale making it a 20-item scale in its final form. Internal consistency was acceptable for the total scale (α = 0.84) and the four subscales: Factor 1: Nursing care of ECMO-SP not related to the ECMO device (α = 0.90), Factor 2: Activities on ECMO device in emergency (α = 0.82), Factor 3: ECMO device calibrating and monitoring (α = 0.72), and Factor 4: Medication and blood administration through ECMO device (α = 0.73). When examined in confirmatory factor analysis, the 20-item scale yielded acceptable fit indices. A positive correlation was found between perceived ECMO knowledge and all four factors of the nursing activities in the Care of ECMO-SP scale.
The 20-item scale examining nursing activities in the care of ECMO-SP is ready for use for clinical, educational, and research purposes.
Because there are still no standards for nursing care of ECMO-SP and no agreed quality indicators, this novel scale may help in building such standards and quality indicators.
护士是提供体外膜肺氧合支持患者（ECMO-SP）护理的多学科团队的成员。目前还没有有效的、可靠的测量方法来评估 ECMO-SP 护理中的护理活动。
开发和评估一种新的 27 项护理活动在 ECMO-SP 护理中的测量工具的心理测量学特性。
本研究采用便利抽样法，于 2022 年 3 月至 6 月在以色列招募了 76 名注册护士（平均年龄 41.3±8.7 岁，71%为女性）。护士使用在线调查软件 Qualtrics 参与调查。评估了量表的内容和结构效度以及内部一致性。参与者还完成了 ECMO-SP 治疗感知知识和技能量表。使用 Pearson 相关分析检查了护理活动在 ECMO-SP 护理中的相关性和与 ECMO 知识的相关性。
探索性因素分析提取了四个因素，从 27 项量表中剔除了 7 项，最终形成了 20 项量表。总量表（α=0.84）和四个分量表的内部一致性是可以接受的：因子 1：与 ECMO 设备无关的 ECMO-SP 护理（α=0.90），因子 2：紧急情况下 ECMO 设备上的活动（α=0.82），因子 3：ECMO 设备校准和监测（α=0.72），因子 4：通过 ECMO 设备给药和输血（α=0.73）。在验证性因素分析中，20 项量表得出了可接受的拟合指数。感知 ECMO 知识与护理活动在 ECMO-SP 护理中的四个因素呈正相关。
用于评估护理活动在 ECMO-SP 护理中的 20 项量表已准备好用于临床、教育和研究目的。
由于目前还没有 ECMO-SP 护理的标准，也没有达成共识的质量指标，因此这种新的量表可能有助于建立这些标准和质量指标。
