Effects of preoperative teaching of the use of a pain scale with patients in the PACU.

Clinical observations have shown that patients arriving in the PACU who had no experience using a pain scale had more difficulty rating their pain in the immediate postoperative period. The purpose of this pilot study was to determine if preoperative instruction on the use of a pain scale would improve the patient's ability to self-report pain in the Phase I PACU. The sample consisted of 50 English speaking, orthopedic patients between the ages of 19 and 75 years.
