Abstract
Background: Suboptimal adherence to guidelines is a common phenomenon in clinical settings. Studies regarding the complexity of tasks, cognitive load, and adherence to guidelines among clinical nurses are noteworthy, but limited.
Purpose: To investigate whether cognitive load mediates the association between task complexity and guideline adherence in clinical nurses.
Methods: In total, 580 clinical nurses from 8 tertiary hospitals were included in the cross-sectional survey. A self-reported survey included guideline adherence, task complexity, and cognitive load. We conducted correlation and multiple linear regression analysis and performed a mediation effect analysis using PROCESS with 5000 resamples.
Results: The linear regression showed that task complexity significantly predicted intrinsic cognitive load (a1 = 0.322, p < 0.001), intrinsic cognitive load significantly predicted guideline adherence (b1 = -0.113, p < 0.001), and task complexity had a direct impact on guideline adherence (c' = 0.126, p < 0.001). Both intrinsic cognitive load (effect size = -0.037, 95%CI: -0.061, -0.019) and germane cognitive load (effect size = 0.180, 95%CI: -0.269, -0.171) played a partial mediating effect between task complexity and guideline adherence among nurses, contributing to 53.16% of the overall effect.
Conclusions/implications for practice: Nursing administrators should prioritise the cognitive load for clinical nurses when allocating intricate assignments.
背景：对指南的次优遵守是临床环境中的常见现象。关于任务复杂性、认知负荷和临床护士对指导方针的依从性的研究值得注意，但有限。目的：探讨认知负荷是否在临床护士任务复杂性与指南依从性之间起中介作用。方法：对8所三级医院580名临床护士进行横断面调查。一项自我报告的调查包括指南依从性、任务复杂性和认知负荷。我们进行了相关和多元线性回归分析，并使用PROCESS对5000个样本进行了中介效应分析。结果：线性回归结果显示，任务复杂性显著预测内在认知负荷（a1 = 0.322, p b1 = -0.113, p c' = 0.126, p）。结论/实践启示：护理管理者在分配复杂任务时应优先考虑临床护士的认知负荷。
