Testing a model of adoption and continued use of Personally Controlled Electronic Health Record (PCEHR) system among Australian consumers: a preliminary study

This study aims to investigate factors influencing adoption and continued use of PCEHR system among consumers (individual users) in Australia. The data collected via online questionnaire survey were analysed via a Structural Equation Modelling (SEM) approach. The results indicate that: (1) “External Factors & Influences” and “Individual Differences” are significant factors that influence “Perceived Benefits” of the PCEHR system, which in turn influence adoption of the PCEHR system; (2) “External Factors & Influences”, “Individual Differences”, and “PCEHR System Characteristics” are significant factors that influence “Perceived User Friendliness” of the PCEHR system, which in turn influence adoption of PCEHR system; (3) “Facilitating Factors” are significant factors that influence both “Realized Benefits” and “Realized User Friendliness”, which in turn influence continued use of PCEHR system; and (4) “Voluntariness of Adoption” and “Voluntariness of Continued Use” are significant factors that influence both adoption and continued use of the PCEHR system respectively.
