EP112 Patient centered analgesia after joint revision arthroplasty: outcomes from pain out study in the hospital of traumatology and orthopaedics

<h3>Background and Aims</h3> Post-operative pain has been studied quite comprehensively in recent years, however, studies on postoperative pain and its management following revision arthroplasty are understudied. As a result, standardized management protocols regarding revision arthroplasty are lacking. Patients undergoing revision arthroplasty often present with substantial pain pre-operatively, which rationalizes the importance of this study. The aim of our study is to evaluate the intensity and characteristics of postoperative pain following joint revision arthroplasty, to assess the effectiveness of pain management and identify factors that influence pain outcomes and satisfaction <h3>Methods</h3> A combined retrospective-prospective study of 38 patients on first postoperative day following joint revision arthroplasty. Data were collected using standardized pain register PAIN OUT questionnaires and patient medical records. Statistical analysis was done using MedCalc version 23.2.1. <h3>Results</h3> Median worst pain score was 4.0 [2.0–6.8], while treatment satisfaction was high (9.0 [8.0–10.0]). Patients spent a median of 20.0% [10.0–40.0] of the first postoperative day in severe pain. Pain interfered most with movement in bed (3.5 [1.2–5.0]) and less with sleep (1.0 [0.0–3.8]). Patient participation in decisions was the only significant predictor of treatment satisfaction (ρ=0.326, p=0.046). There were no statistically significant differences in outcomes across gender, surgery type, or anesthesia technique. Despite high satisfaction, 65.8% of patients desired more information on pain management. <h3>Conclusions</h3> Patient participation in pain management decisions correlates with higher satisfaction regardless of objective pain levels. These findings highlight the need for greater patient involvement in postoperative pain management
