The case of the cold thermometers

Background: A temporal artery thermometer was introduced at our hospital. Immediately staff noted subnormal temperature readings. Methods: Three serial evaluations of patient temperatures were done: August 2000 (initial), September 2000 (posteducation), and December 2000 (after removal of temporal artery thermometer). Results: In the initial review, 89% of the readings were < 98.6°F. Comparison of the readings from the last and first surveys showed a statistical increase in the proportion of readings ≥100.0°F and decrease of readings <98.6°F (P < .001). Conclusions: Our experience underscores the importance of performance data for quality monitoring of new products. (Am J Infect Control 2003;31:57-9.)
