The effect of ambient outside temperatures on scoop stretchers

Scoop stretchers are commonly used in the prehospital care of trauma patients. Patients' clothing is often removed early in the care pathway. There may be unidentified risks if scoop stretchers are particularly cold. The primary aim of this research was to establish if there is a positive correlation between scoop temperatures and outside temperatures when this equipment is stored without access to vehicle heating. The authors recruited volunteers at ambulance locations across Scotland to measure scoop temperatures using infrared thermometers. These were compared to outside temperatures at that time. Data were subject to bivariate quantitative analysis to assess correlation strength. Results demonstrated that there was a moderate-to-strong correlation between scoop temperatures and outside temperatures (mean +3.0°C; P<0.001). There was no significant difference for other variables measured. Without active heating, scoop stretchers will be only marginally warmer than the outside temperature, sometimes colder than the outside temperature and sometimes below freezing point.
