The implantation of hospital information systems (HISs) has grown dramatically in recent years. Understanding the success rate of HIS is key in health organizations. In this study, a validated questionnaire for HISs evaluation based on the Information System Success Model (ISSM) has been provided. In addition, the HIS success rate was determined.
The current study was conducted at one of the largest teaching hospitals in eastern Iran. The 44-items questionnaire was developed for data gathering. The questionnaire covered ISSM dimensions, which include analysis of quality system, quality of information, quality service, system use, usefulness, satisfaction, and net benefits. Content validity, constructs validity, and reliability of the ISSM questionnaire was measured. HIS success rate has been determined and categorized based on users' perspective as follows: appropriate (75%≤HIS success rate), moderate (50%≤HIS success rate<75%), low coverage (25%≤HIS success rate<50%), and poor (coverage rate<25%).
In total, 253 users participated in the study. The ISSM questionnaire was validated by an expert panel with CVI: 85.12% and CVR: 88.22%. The overall Cronbach's alpha value of the instrument was determined as 92.2%. Nine factors with eigenvalues greater than 1.00 were identified, jointly accounting for 66.91% of the total variance. The value of KMO was.866 showed that the sample size was adequate for factor analysis. The highly significant Bartlett's test (p<0.000) indicated that variables were correlated and the factor analysis was appropriate. Our results demonstrated that the total mean of HIS success was "moderate" base on the users' point of view.
The findings of the current study, provide valuable scientific evidence for key affecting factors on hospital EHR in Iran as a developing country.
近年来，医院信息系统（HIS）的植入显著增加。了解HIS的成功率是卫生组织的关键。在本研究中，提供了一份基于信息系统成功模型（ISSM）的经过验证的HIS评估问卷。此外，还确定了HIS的成功率。
本研究在伊朗东部最大的教学医院之一进行。为收集数据编制了包含44个条目的问卷。该问卷涵盖了ISSM维度，包括质量体系分析、信息质量、质量服务、系统使用、有用性、满意度和净效益。对ISSM问卷的内容效度、结构效度和信度进行了测量。根据用户视角确定了HIS成功率并进行分类如下：合适（HIS成功率≥75%）、中等（50%≤HIS成功率＜75%）、覆盖低（25%≤HIS成功率＜50%）和差（覆盖率＜25%）。
共有253名用户参与了研究。ISSM问卷经专家小组验证，内容效度指数（CVI）为85.12%，内容效度比率（CVR）为88.22%。该工具的总体克朗巴哈系数值确定为92.2%。识别出9个特征值大于1.00的因子，共同解释了总方差的66.91%。KMO值为0.866，表明样本量足以进行因子分析。高度显著的巴特利特检验（p＜0.000）表明变量相关且因子分析合适。我们的结果表明，从用户角度来看，HIS成功的总平均值为“中等”。
本研究结果为伊朗作为一个发展中国家医院电子健康记录的关键影响因素提供了有价值的科学证据。
