“Wow thats cold!”
It’s a common statement after applying the probe to a patient, and wouldn’t you love to know the answer to the age old question, “Does gel temperature matter for patient satisfaction?”… While we have some data suggesting improved patient satisfaction scores with POCUS, but could those scores be better if the gel was warmed? Or perhaps would all the improvement in satisfaction scores be lost with cool gel?
This group performed bedside ultrasound using heated gel (102F) or room-temperature gel (82.3F – quite the warm department!). The investigators even went so far as to trying to blind those performing the study with a heat-resistant glove (!) – and even validated gel temperature through weekly quality assurance measurements throughout the study period. The investigators informed all patients that the study entailed investigation into various measures to improve patient satisfaction with POCUS, but did not inform them of their specific focus on gel temperature. After POCUS was performed, patients completed the following survey: “How satisfied are you with the experience of having a bedside ultrasound today?” (on a 100-mm visual analogue scale (VAS) for satisfaction), as well as, “Are you satisfied with the care you received today in the emergency department (yes or no), as well as “How professional was the provider who performed your bedside ultrasound?” (A Likert scale spanning 1-5)
All in all, 59 patients underwent randomization to POCUS with room-temperature gel and 61 underwent randomization to heated gel.
In the end, heated gel made no difference for any of the three questions posed to patients. While I think those of us utilizing warm gel were probably making space in the blanket warmer, it’s nice to know that this intervention, while nice, does not make much of a difference, and a “special” warmer specific for gel in your department is probably unnecessary.
