A new pain assessment tool known as BPAT (Behavior Pain Assessment Tool) may be the answer to this problem. This tool evaluates eight behavioral clues, including facial expression, muscle responses, and verbal expressions to determine a patients pain level. While being studied, this new pain tool was used on persons who were able to communicate, then compared to what the patient's rating on a ten point scale. It was reported to be reliable in two of every three patients studied. Further evaluation will help to determine how the BPAT's accuracy can be enhanced.
