ABSTRACT
BACKGROUND: Postoperative pain and agitation is an ongoing issue among patients undergoing total knee replacement (TKR). Use of complementary therapies such as music may improve outcomes when combined with medical therapy. AIM: The purpose of this quality improvement (QI) initiative was to evaluate postoperative use of classical music among adult patients who have undergone TKR on reported agitation, pain, and opioid use. DESIGN: A prospective evidence-based QI initiative. SETTING: A midwestern hospital post-anesthesia care unit. PARTICIPANTS: Postoperative patients who had undergone TKR. METHODS: Classical piano music was played postoperatively using an MP3 device. Adult patients who were undergoing TKR were consecutively offered music during their recovery period in the PACU. Agitation was measured using the Richmond Agitation Sedation Score (RASS). Patient perceived pain was measured on a scale of 0-10 with 0 being no pain and 10 being extreme pain. Opioid use was measured using the morphine milligram equivalents (MME). FINDINGS: A total of (n=40) patients received music and (n=50) patients received standard care without music. RASS was significantly lower in the music group than in the baseline non-music group X2 (1, N = 89) = 17.8, p < .001. Patient reported pain scores were significantly lower in the music group, 3.98(SD = 2.71), compared to the baseline non-music group, 6.27(SD = 2.60). Opioid use was also significantly decreased in the music group to MME 9.51(SD = 8.62) compared to the baseline non-music group 13.38 (SD = 9.71). CONCLUSION: Music is an effective nonpharmacologic intervention in decreasing agitation, pain, and opioid use among patients undergoing TKR. These findings provide evidence for nurses to incorporate music as an adjunctive approach to enhance the patient's experience and improve outcomes.
