Abstract
Patient Portals are widely used in healthcare to guarantee access to health information. However, while the adoption of patient portals by physicians has increased over the past three years, the adoption and use by patients is still quite low. This research study used the Theory of Planned Behavior (TPB) to identify factors that influence an individual’s decision to adopt and use patient portals. Two additional factors, such as privacy and trust that hinder individuals were added to the model.
An online survey was created to explore the impact that TPB constructs (subjective norm, attitude, self-efficacy, and intent) and items for privacy and trust had on patient portal adoption. Responses were gathered from 453 individuals using a Qualtrics survey response team. Data were analyzed using Smart PLS.
Attitude, subjective norm, self-efficacy, intent, privacy, and trust of information all impacted an individual’s decision to use a patient portal. Privacy construct shows a negative effect on an individual’s intention to adopt and use a patient portal.
TPB is a good theory to explore why individuals use or don’t use patient portals. This research explored the TPB to identify factors which influence an individual’s intent to adopt a patient portal. The TPB model was used to determine what influenced individuals to adopt and use patient portals. Two additional constructs were added to explore their role in an individual’s decision to use the portal: privacy and trust of information. When analyzing the results, all constructs including privacy and trust were significant in predicting whether an individual would use patient portal; however, privacy shows this desire will have a negative effect on their intent to use a patient portal.
