Titel och sammanfattning

Populärvetenskaplig sammanfattning

Background: Extensive research has been devoted to developing methods for assessing core body temperature, and to determine which method is most accurate. A number of wireless dermal thermometers for home use are presently available, but their relation to core body temperature and suitability for use in clinical research has hitherto not been assessed. The aim of the current study was therefore to evaluate such dermal thermometers by comparing them to a rectal thermometer.

Methods: Four wireless dermal thermometers for home use (FeverSmart, iThermonitor, Quest Temp Sitter, Thermochron iButton) were applied to 15 patients during 24 hours, and rectal temperature was measured at four occasions.

Conclusions: The dermal thermometers tested here are not accurate enough for most types of clinical research. On the other hand, other options for non-invasive temperature measurements are few. The two thermometers with the least unsatisfactory performance profile in our evaluations were the Feversmart and iThermonitor systems.

Vetenskaplig sammanfattning

Background: Extensive research has been devoted to developing methods for assessing core body temperature, and to determine which method is most accurate. A number of wireless dermal thermometers for home use are presently available, but their relation to core body temperature and suitability for use in clinical research has hitherto not been assessed. The aim of the current study was therefore to evaluate such dermal thermometers by comparing them to a rectal thermometer.

Methods: Four wireless dermal thermometers for home use (FeverSmart, iThermonitor, Quest Temp Sitter, Thermochron iButton) were applied to 15 patients during 24 hours, and rectal temperature was measured at four occasions.

Results: Pearson correlation revealed moderate correlation for the Feversmart (r=0.75), iThermonitor (r=0.79) and Thermochron iButton (r=0.71) systems. The Quest Temp Sitter system malfunctioned repeatedly, and the correlation (r=0.29) for this method should therefore be assessed with caution. All dermal thermometers rendered lower average temperatures than Terumo c405 (Feversmart -0.70±0.65 ºC; iThermonitor -0.77±0.53 ºC, Quest Temp Sitter -1.18±0.66 ºC and Thermochron iButton-0.87±0.65 ºC). Sensitivity of the dermal thermometers for detecting core temperatures ≥38.0 ºC was low, ranging from 0.33-0.6, but improved to 0.60-0.80 after adjusting temperatures by the methods’ average deviation from rectal temperature.

Conclusions: The dermal thermometers tested here are not accurate enough for most types of clinical research. On the other hand, other options for non-invasive temperature measurements are few. The two thermometers with the least unsatisfactory performance profile in our evaluations were the Feversmart and iThermonitor systems.
