Abstract: Employs human-centred design (HCD) methods to explore how the medical devices that make up the Waitemata District Health Board's (Waitemata DHB) Outpatient Intravenous Antibiotic (OPIVA) service could be redesigned to improve the experiences of patients within the service. Surveys patients and district nursing staff about improving the usability, aesthetics and ergonomics of the elastomeric infuser and redesigning the storage bag to be wearable under clothing. Proposes a new system to replace the surgical tape used to hold the IV lines in place and advocates for patient experience inclusion in the redesign of the devices.
