In April 2020, the ICU App was developed using AppSheetTM, a low-code, mobile application builder. The app was introduced to the JHH ICU in an attempt to increase the use of the procedural logbook, previously limited to a paper-based logbook kept in a communal folder. The app combined a read-only daily unit roster with an interactive procedural logbook.

Interface design focused on rapid data entry, minimum text requirements, and field-level automation. Individuals would enter de-identified patient data regarding the CVC insertion procedure using their mobile device, and the data would be immediately uploaded to a secure, central, web-based database. The application could be installed on both iPhone and Android operating systems. The app was made available to all doctors working in the unit from April 6, 2020.
