Science does not stand still and now, thanks to modern technologies, doctors will be able to objectively assess the level of pain by the patient's face. More precisely, special software developed by scientists from the University of California and San Diego Medical School will do it for them.
The new system is proposed to be used even for young patients, since many children cannot objectively determine the level of pain they experience, which, in turn, can complicate diagnosis. The special software is based on the Facial Action Coding System (FACS). Using a video camera, the system recognizes facial movements of the patient's face and, based on them, estimates the level of pain in real time.
The system has already been successfully tested on 60 patients aged 6 to 18 years who underwent laparoscopic removal of the appendix. It is argued that neither ethnicity, nor race, nor gender affects the accuracy of the algorithm.
"The software has shown excellent accuracy in assessing pain, " writes Dr. Ginny Huang, one of the authors of the study article.
We add that the new system has one more indisputable advantage over the existing methods, which is that it can be used continuously. It is difficult to say when it will be used in hospitals.
