A ward comparison between the One Touch II and Glucometer II blood glucose meters

Abstract

A 6-week clinical evaluation of the One Touch II blood glucose meter was performed in a medical ward specializing in diabetic patients and compared to the existing Glucometer II system. Nursing staff trained in both methods performed 267 capillary blood glucose measurements using the two meters. A reference capillary blood glucose was performed simultaneously on 129 of these occasions using a Yellow Springs Instrument analyser. The One Touch II correlated better with the reference (r = 0.97) than the Glucometer II (r = 0.86) and was equally close or closer to the Yellow Springs Instrument on 82% of occasions. A greater proportion of samples measured by the One Touch II were within 15% of the reference value (83% vs 66%). There were also 17 cases where the One Touch II was able to give a measurement which was outwith the analytical range of the Glucometer II. A questionnaire revealed the nursing staff unanimously preferred using the One Touch II to their present meter. It is concluded that in a ward setting the One Touch II meter showed improved accuracy, usefulness in its wider analytical range, and a greater user preference in comparison to the Glucometer II.
