A total of 1,356,042 pain scores were analyzed over the 3-year time period. Based on the data analysis, our team sketched the trend in pain among hospitalized cancer patients and developed the pain relief index (PRI).

Through the calculation of two fixed pain intensity scores, and taking into account the goal of pain relief, optimize the existing indicators of pain relief, and develop a symptomatic pain relief assessment index - pain relief index.

Through this system, patients and their families can check the pain record and the pain calculation index calculated by the system at any time, and give feedback to the face. If the pain has improved, the smile will appear, and the face will be crying, so that the patient and the family can understand the pain relief results.
