Case Study for Curiato’s Smart Sensor Platform

Presented at the Society of Advanced Wound Care (SAWC) virtual symposium on July 24-26, 2020, this presentation poster written by an acclaimed panel including lead author Nicola Waters, PhD, RN, MSc highlights Curiato’s findings from its initial trial conducted at Toronto Grace Health Centre.

The trial was focused on the feasibility of a new novel smart sensor platform for monitoring patients at risk of pressure injuries. Interface pressure and skin microclimate have been identified as critical risk factors in pressure injury development. At present, continuous monitoring of these conditions is currently not possible in most clinical settings, and reviews of monitoring technologies show that sensor devices are associated with a substantial reduction in the risk of pressure injuries.
The study centred on adults that were hospitalized for more than 18 hours a day who were at-risk of pressure injuries, as defined by the InterRAI Pressure Injury Risk Assessment Scale, with or without a present pressure injury. Participants received the usual standard of care, including manual repositioning as appropriate, while placed on the smart surface for timed intervals. A total of 104 participants were included in the study.

The smart surface platform is comprised of an array of sensors embedded within a thin, flexible surface that is placed underneath the bed sheet while covering the mattress. Sensors gather data from the subject’s bedding surface in the form of interface pressure (mmHg), temperature (Celsius) and humidity (0-100% RH) at four second intervals. For the initial analysis, data related to mobility/activity status were extracted from the head to toe assessment forms. A comparative statistical analysis was conducted between the two datasets.

Results concluded that manual repositioning and visual inspection of the skin require resources, especially time, that may be limited due to high patient acuity and competing demands. The novel smart sensor platform can continuously measure pressure injury risk factors accurately and has the potential to enhance pressure injury prevention approaches.
