An mHealth application for chronic vascular access: A multi-method evaluation

BackgroundHealthcare consumers require diverse resources to assist their navigation of complex healthcare interactions, however, these resources need to be fit for purpose. AimIn this study, we evaluated the utility, usability and feasibility of children, families and adults requiring long-term intravenous therapy using a recently developed mobile health application (App), intravenous (IV) Passport. DesignMulti-site, parallel, multi-method, prospective cohort study. MethodsA multi-site, multi-method study was carried out in 2020-2021, with 46 participants (20 adults, 26 children/family) reporting on their experiences surrounding the use of the IV Passport for up to 6 months. ResultsOverall, utility rates were acceptable, with 78.3% (N = 36) using the IV Passport over the follow-up period, with high rates of planned future use for those still active in the project (N = 21; 73%), especially in the child/family cohort (N = 13; 100%). Acceptability rates were high (9/10; IQR 6.5-10), with the IV Passport primarily used for documenting new devices and complications. Thematic analysis revealed three main themes (and multiple subthemes) in the qualitative data: Advocacy for healthcare needs, Complexity of healthcare and App design and functionality. ConclusionSeveral recommendations were made to improve the end-user experience including 'how to' instructions; and scheduling functionality for routine care. Implications for the Profession and/or Patient CareThe IV Passport can be safely and appropriately integrated into healthcare, to support consumers. ImpactPatient-/parent-reported feedback suggests the Intravenous Passport is a useful tool for record-keeping, and positive communication between patients/parents, and clinicians. Reporting MethodNot applicable. Patient ContributionConsumers reported their experiences surrounding the use of the IV Passport for up to 6 months.
