RESUMEN
Using of EMR in health services and organizations is steadily increasing for quality improvement, cost effectiveness and performance development. However, no validated national and international instruments (scale, questionnaire, index, and inventory) have assessed the effectiveness, satisfaction, health care savings, patient safety and cost minimization of electronic medical and health systems from the viewpoint and perceptions of nurses in Turkish health services. The perceptions of health care professionals especially physicians and nurses can contribute important information that may predict their acceptance of EMR and desired mode of use for EMR, evaluation performance of EMR thus guiding EMR implementation in hospitals. This article is a report of validation of the instrument to measure nurses' views on the use, quality and user satisfaction with EMR in Turkish health system. Items in the questionnaire were designed and obtained following O.G. Otieno, H. Toyama, M. Asonuma, M. Kanai-Pak, K. Naitoh's questionnaire about Use, Quality and User Satisfaction with EMR systems. Reliability and validity were examined and investigated in terms of responses from 487 nurses from one education hospital in Ankara, Turkey. This study was planned and conducted at a university hospital. The validation process was based on construct validity in this study. The response rate was 74.92%. Cronbach's alphas of three factors (use, quality and satisfaction of EMR) ranged from 0.78 to 0.94. Goodness-of-fit indices from the confirmatory factor analysis showed a reasonable model fit. Results of confirmatory factor analysis showed that χ2 statistic indicated significant result (p < 0.001) and model fit was acceptable according to relative χ2 statistic (χ2/df = 2.8 < 5). Further validation of the instrument could yield positive results in health systems in the different countries. Also further validation and reliability studies could be planned on physicians and other health professionals.

AIM: This paper is a report of the development of an instrument to measure nurses' views on the use, quality and user satisfaction with electronic medical records systems. BACKGROUND: Use of electronic medical records systems in hospitals is steadily increasing, yet no validated instruments have assessed the effectiveness of these systems from the viewpoint of nurses. METHOD: Items were designed following a literature review based on three main constructs: use, quality and user satisfaction with electronic medical records. Reliability and validity were examined based on responses from 1,666 nurses from 42 hospitals in Japan in February 2006. Exploratory factor analysis was conducted to determine the degree to which each item within a construct was associated. The reliability of each resultant factor was computed using Cronbach's alpha coefficient. Content validity was addressed by basing the items on previous surveys and review of the instrument by a panel of nurses experienced in nursing informatics. Construct validity was examined through factor analysis and correlational analyses. FINDINGS: Extent of 'use' of electronic medical records resulted into three factors with good factor loadings, but only two had acceptable reliability. 'Quality' of electronic medical records had two factors with good factor loadings and reliability. 'User satisfaction' with electronic medical records had three factors, but only one had acceptable reliability. 'Use' and 'quality' constructs were positively correlated with 'user satisfaction'. CONCLUSION: The final instrument incorporates 34 items from the original 44-item pool. Initial validity results were positive and therefore the instrument can be used in evaluating electronic medical records in hospitals.
