Spatially Integrated Electronic Health Record Prototype Improves Usability and Reduces Cognitive Load for Intensive Care Nurses: A Randomized Crossover Trial.

An Spatial Awareness Integrated Electronic Health Record prototype mirroring intensive care unit room layout enabled faster, more accurate documentation with lower perceived workload than a linear flowsheet interface.

Stated intention to adopt was higher and inversely associated with workload; differences in SUS and Technology Acceptance Model perceived usefulness scores favored the spatial interface but did not reach statistical significance in this sample.
