Blockchain-based personal health record (PHR) is an impending blockchain use case that supports patient-centered care and interoperability in the healthcare industry. This paper studies the adoption of blockchain-based PHR by individuals. It proposes a multi-perspective theoretical framework containing the unified theory of acceptance and use of technology (UTAUT) and initial trust model (ITM) to understand how individuals鈥� perceptions and formation of trust prior to adoption may contribute to their behavioral intention toward adopting blockchain-based medical records. This research empirically tested this model using a cross-sectional questionnaire. Partial least squares structural equation modelling (PLS-SEM) was used to conduct data analysis. The results validate the theoretical model and demonstrate full support for the ITM and partial support for the UTUAT. Entrants in the blockchain-based PHR market are advised to create trustworthy systems, consider partnering with healthcare institutions to boost institution-based trust and design solutions that meet the performance expectations of users.
