BackgroundPatients undergoing total knee arthroplasty (TKA) experience significant postoperative pain and routinely require opioids, yet they often lack knowledge regarding appropriate use and handling of these medications. Evidence suggests that educational interventions in various formats may help reinforce proper usage and improve postoperative pain control. The aim of this study is to compare the institution standard of care (webinar) with two novel educational interventions-one in-person and the other a video recording-that focus specifically on the use of opioids and pain control.MethodsThis prospective, randomized pilot study included 42 patients undergoing TKA. Patients were randomized into one of three groups: (1) webinar: 50 min virtual session standard of care at Hospital for Special Surgery (HSS), (2) in-person education, or (3) video education. The primary outcomes of this study were the number of opioid refill requests through postoperative day (POD) 30 and POD 60. The secondary outcomes evaluated Numerical Rating Scale (NRS) pain scores, opioid consumption in oral morphine equivalents (OME), surveys on medication usage and opioid knowledge, reported medication storage and disposal. We hypothesize that the novel educational interventions, presented either in-person or by video, will lead to a decrease in opioid refills within 60 days compared with current education delivered through virtual webinar.ResultsNo significant differences were found among groups in the number of opioid refill requests, average NRS pain score, or OME consumption at any time point. Opioid refill requests ranged from 0% to 16.7% at POD 30 (Fisher's exact test, p=0.625) and from 0% to 8.3% at POD 60 (p=1.000). The median opioid refill request was zero requests per group from POD 21 to 60 (webinar 0 (0.0, 0.0), in-person 0 (0.0, 0.0), video 0 (0.0, 0.0), Kruskal-Wallis test, p=0.381). Average NRS pain scores were 5 or below for all groups on POD 1, 7 and 14. By POD 7, all groups had an average daily intake OME of 14 or below.ConclusionsOverall, patients in each group did well with postoperative pain management after TKA and had minimal opioid refill requests. There were no statistically significant differences in outcomes of NRS pain scores or opioid usage among groups suggesting that educational interventions were similarly effective. As a pilot trial, study demonstrated successful recruitment and retention of participants, and important feedback was elicited from patients regarding education, as well. Of note, this was a pilot study and was likely underpowered to detect a difference.Trial Registration NumberNCT05593341.© American Society of Regional Anesthesia & Pain Medicine 2024.
