Do augmented physician communication and observational learning reduce postoperative pain in patients undergoing total hip arthroplasty?
This study protocol outlines an RCT to evaluate whether optimizing preoperative expectations through augmented communication and observational learning can improve pain and functional outcomes after total hip arthroplasty.
INTRODUCTION: Osteoarthritis (OA) commonly affects the ageing population, particularly the hip joint. Total hip arthroplasty (THA) is a frequent procedure that relieves pain and improves mobility, though some patients experience persistent postoperative pain. With rising numbers of THA, optimising perioperative care and pain management is crucial to address the growing clinical burden and improve patient outcomes. Positive treatment expectations have shown promise in enhancing outcomes, especially in pain management. This study implements two strategies to optimise the patient's treatment expectations, comprising enhanced physician communication and digital social observational learning. We will examine their separate and combined effects on preoperative expectations, negative emotions, postoperative pain, inflammation and function during recovery up to 12 months postoperatively. METHODS AND ANALYSIS: This randomised controlled trial (RCT) investigates the impact of augmented physician communication and observational learning on treatment expectations and recovery. Participants (n=200) will be randomised into four groups: treatment as usual (TAU), augmented doctor conversation (aDOC), observational learning video (Video) and a combination of both (aDOC+Video). The aDOC group receives empathic communication and targeted information to strengthen self-efficacy. The Video group watches a model patient demonstrating successful recovery. The combined group receives both interventions. Outcomes will be assessed at multiple time points (4 days preoperatively; 1 and 4 days, 4 weeks and 3, 6 and 12 months postoperatively), including subjective pain ratings, mobility and objective physical function. The primary analysis will compare changes in pain intensity across groups. Secondary outcomes will include functional status, self-efficacy, recovery and systemic inflammatory markers. Statistical analysis involves repeated measures ANOVA and post hoc tests for between-group and within-group comparisons. TRIAL REGISTRATION NUMBER: German Clinical Trials Register: DRKS00033212.
Ocokoljic et al. (Sat,) conducted a rct in Osteoarthritis undergoing total hip arthroplasty (n=200). Augmented physician communication (aDOC) and/or observational learning video vs. Treatment as usual (TAU) was evaluated on Changes in pain intensity. This study protocol describes a randomized controlled trial of 200 patients to evaluate whether augmented physician communication and observational learning videos reduce postoperative pain after THA.
