Exploring the Change of Attitude among Healthcare Professionals toward Adopting a National Health Information System: The Case of Jordan

National health information systems (HISs) are spreading globally at a rapid pace. Therefore, it is important to understand the socio-technical factors that influence their adoption by healthcare professionals (HCPs). This study explores the change in attitudes of HCPs toward adopting a national HIS in Jordan. Data were collected from public hospitals and healthcare centers using surveys in two phases over two years and empirically tested using partial least squares (PLS). The first phase results showed that HCPs had positive attitudes toward the national HIS and perceived it to be useful but difficult to use. In the second phase, results showed that users? attitudes positively changed regarding both ease of use and usefulness. This research contributes to both theory and practice by investigating how HCPs? attitudes can be changed regarding adopting a national HIS over time. This provides insights for healthcare providers to better understand and improve HISs adoption among HCPs.
