Abstract

Background: Evaluating healthcare information systems, such as the Electronic Health Records (EHR), is both challenging and essential, especially in resource-limited countries. This study aims to psychometrically develop and validate an instrument (questionnaire) to assess the factors influencing the successful adoption of the EHR system by healthcare professionals in Moroccan university hospitals.

Methods: The questionnaire validation process occurred in two main stages. Initially, data collected from a pilot sample of 164 participants underwent analysis using exploratory factor analysis (EFA) to evaluate the validity and reliability of the retained factor structure. Subsequently, the validity of the overall measurement model was confirmed using confirmatory factor analysis (CFA) in a sample of 368 healthcare professionals.

Results: The structure of the modified HOT-fit model, comprising seven constructs (System Quality, Information Quality, Information technology Service Quality, User Satisfaction, Organization, Environment, and Clinical Performance), was confirmed through confirmatory factor analysis. Absolute, incremental, and parsimonious fit indices all indicated an appropriate level of acceptability, affirming the robustness of the measurement model. Additionally, the instrument demonstrated adequate reliability and convergent validity, with composite reliability values ranging from 0.75 to 0.89 and average variance extracted (AVE) values ranging from 0.51 to 0.63. Furthermore, the square roots of AVE values exceeded the correlations between different pairs of constructs, and the heterotrait-monotrait ratio of correlations (HTMT) was below 0.85, confirming suitable discriminant validity.

Conclusions: The resulting instrument, due to its rigorous development and validation process, can serve as a reliable and valid tool for assessing the success of information technologies in similar contexts.

开发并验证一种工具，用于评估在医院环境中使用电子病历的视角。

背景：对电子病历（EHR）等医疗信息系统进行评估既具有挑战性又十分必要，尤其是在资源有限的国家。本研究旨在从心理统计学角度开发和验证一种工具（调查问卷），以评估影响摩洛哥大学医院医护人员成功采用电子病历系统的因素：问卷验证过程分为两个主要阶段。首先，使用探索性因素分析法（EFA）对从 164 名参与者的试点样本中收集的数据进行分析，以评估保留因素结构的有效性和可靠性。随后，在 368 名医疗保健专业人员样本中使用确认性因子分析（CFA）确认了整体测量模型的有效性：结果：修改后的 HOT-fit 模型由七个构念（系统质量、信息质量、信息技术服务质量、用户满意度、组织、环境和临床绩效）组成，其结构通过确认性因子分析得到了证实。绝对拟合指数、增量拟合指数和准拟合指数均显示出适当的可接受性水平，从而肯定了测量模型的稳健性。此外，该工具还表现出足够的可靠性和收敛有效性，其综合可靠性值在 0.75 至 0.89 之间，平均方差提取（AVE）值在 0.51 至 0.63 之间。此外，AVE 值的平方根超过了不同构念对之间的相关性，异质-单质相关比（HTMT）低于 0.85，证实了适当的判别效度：结论：经过严格的开发和验证过程，该工具可作为一种可靠有效的工具，用于评估信息技术在类似情况下的成功与否。
