Comparison of Ease of Learning of Four Glucose Meters

This study examined the ease with which subjects were able to learn to use four blood glucose meters: Glucoscan 3000, Glucometer II, Accu-Chek II, and Diascan. Diabetes educators taught use of meters to 42 subjects in groups of three or four over two hours. Order of presentation was controlled by repeated measures Latin Square design. Twenty-five minutes were allowed for instruction and return demon stration of each meter. Subjects performed tests until three consec utive tests fell within the expected range or the allotted time was completed. Visual analog scales (eg, ease of learning, calibration, starting, testing, reading, and lack of confusion) were completed by subjects immediately following use of each meter. Statistically significant differences were found between meters. Overall ranking (easiest to hardest) was Glucoscan 3000 > Diascan > Glucometer II > Accu-Chek II. In addition to consideration of these results, educators still need to consider the individual in selecting the appropriate meter.
