Understanding EHRs continuance intention to use from the perspectives of UTAUT: practice environment moderating effect and top management support as predictor variables

This study attempts to comprehend factors influencing nurses' continuance intention to use electronic health records (EHR) system in Jordan since they as the key service providers in healthcare services are main users of the system. Their acceptance and usage of the system are imperative to evaluate the system's implementation success. A cross-sectional survey is conducted on the fully implemented EHR system public hospitals. Study framework is based on the extended model of the unified theory of acceptance and use of technology (UTAUT) and top management support (TMS). Results reveal effort expectancy, performance expectancy and facilitating conditions positively influence nurses' continuance intention to use and top management support as significant and negatively related to nurses' continuance intention to use. Results also disclose relationship between social influence and continuance intention to use as not significant. Multi-group analysis result indicates stronger relationship between effort expectancy and continuance intention to use is evident to ward nurses than special unit nurses. Findings confirm on the necessity to support new technologies specifically EHR system in hospitals and contributes to UTAUT theory through revealing the impact of top management support on continuance intention to use and establishing relevant measurement accuracy of study framework in Jordanian context.
