ABSTRACT
BACKGROUND: This study analyzed patient engagement with a virtual patient navigation platform (VPNP) designed to help guide bariatric surgery candidates through the complex pre-operative workup for surgery. METHODS: Data on baseline sociodemographic and medical history was collected on patients enrolled in the bariatric program at a single academic institution between March and May 2021. The System Usability Scale (SUS) survey was administered to assess VPNP usability. Two groups emerged: "engaged" (ENG; n = 30) who activated their accounts and completed the SUS, and "not-engaged" (NEG; n = 35) who did not activate their accounts (n = 13) or did not use the app (n = 22) and were therefore ineligible for the SUS survey. RESULTS: Analyses demonstrated that only insurance status differed between groups (private insurance: 60% versus 34.3% for ENG versus NEG, respectively; p = 0.038). SUS survey analysis demonstrated high perceived usability (median score = 86.3), corresponding to the 97th percentile of usability. The top three reasons for disengagement included being too busy (22.9%), not being interested (20%), and being unsure about the purpose of the app (20%). CONCLUSIONS: The VPNP scored in the 97th percentile of usability. However, given a majority of patients did not engage with the app, and engagement was associated with completing pre-surgery requirements faster (unpublished), future work will focus on mitigating identified reasons for patients not engaging.
