Role of Texting as a Source of Cognitive Burden in a Pediatric Cardiovascular ICU.

Abstract

To characterize frontline provider perception of clinical text messaging and quantify clinical texting data in a pediatric cardiovascular ICU (CICU). This is a mixed-methods, retrospective single center study. A survey of frontline CICU providers (pediatric fellows, nurse practitioners, and physician assistants) was conducted to assess attitudes characterizing text messaging on cognitive burden. Text messaging data were abstracted and quantified between January 29, 2020, and April 18, 2020, and the patterns of text messages were analyzed per shift and by provider. The survey was completed by 33 of 39 providers (85%). Out of responders, 78% indicated that clinical text messaging frequently or very frequently disrupts critical thinking and workflow. They also felt that the burden of messages was worse during the night shift. Through abstraction, 31 926 text messages were identified. A median of 15 (interquartile range: 12-19) messages per hour were received. A median of 5 messages were received per hour per provider during the day shift and 6 during the night shift. From the entire study period, there were total 2 hours of high-frequency texting (≥15 texts per hour) during the day shift and 68 hours during the night shift. In our study, providers in the CICU received a large number of texts with a disproportionate burden during the night shift. Text messages are a potential source of cognitive overload for providers. Optimization of text messaging may be needed to mitigate cognitive burden for frontline providers.
