RI Witness System

Reducing human error in IVF with electronic witnessing

RI Witness is an electronic witnessing system which Fertility North uses in the embryology laboratory. This system improves traceability and quality control, while reducing laboratory based risk.

Studies done on the system concluded that “RI Witness™ accurately recorded all lab procedures, and identified a stable true human error rate which compares favourably to published error rates of 0.2-5% for similar clinical lab activities. Data suggests an immediate improvement of documentation and an improvement in system usage after a short time. Other benefits include the reduction of staff workload and distractions, increased SOP compliance whilst also improving the accuracy and efficiency of producing witnessing, traceability, productivity and operator audits. This is the first time an accurate rate of human error in an IVF lab has been calculated.”
