OBJECTIVES: Mobile patient portal app use has been associated with improved disease management through better medication adherence, increased use of preventive services, and enhanced patient-provider communication. However, adoption remains limited. This study aimed to identify key drivers of mobile portal app use by extending the Unified Theory of Acceptance and Use of Technology (UTAUT).
METHODS: We hypothesized that app use would be more likely when individuals perceived the app as useful, easy to use, beneficial for health management outcomes, and low risk to privacy. Subjective norm was hypothesized to predict perceived usefulness. Perceived behavioral control was also examined as a moderator of the intention-behavior relationship. Data were collected from U.S. adults using an online survey platform. Hierarchical multivariate linear regressions were conducted while controlling for multiple covariates.
RESULTS: Analyses included 386 respondents (mean age = 57.4±16.2 years; 53.6% female). Results showed that individuals who felt stronger social expectations to use the app were more likely to perceive it as useful (regression coefficient (β) = 0.22, p < 0.0001), which in turn increased their intention to use it (β = 0.40, p < 0.0001). Perceived ease of use (β = 0.85, p < 0.0001) and outcome expectancy (β = 0.53, p < 0.0001) were positively related to behavioral intention. Lower perceived privacy risk was also related to higher intention (β = 0.41, p < 0.0001). Notably, perceived behavioral control significantly moderated the intention-behavior relationship, indicating that intentions were more likely to translate into actual use when individuals felt confident in their ability to use the app’s features (β’s = 0.22 to 0.24, p < 0.001).
CONCLUSIONS: These findings provide a foundation for developing targeted interventions to promote mobile patient portal app use. Identifying key drivers of app use may inform evidence-based decision-making for digital health implementation in value-based care settings.
