Do perioperative psychological interventions reduce postsurgical pain and disability in adults?
Perioperative psychological interventions, particularly those delivered post-surgery by psychologists, significantly reduce both acute and chronic postsurgical pain and disability.
ABSTRACT: Many patients experience pain after surgery. Psychological factors such as emotion and cognition are shown to be associated with the development of acute and chronic postsurgical pain (CPSP). Therefore, the question arises whether targeting these psychological factors can reduce negative postsurgical outcomes. The aim of the current review was to investigate the efficacy of perioperative psychological interventions in reducing (sub)acute postsurgical pain and CPSP and disability in adults. Randomized controlled trials were identified through 4 databases (Web of Science, PsychINFO, PubMed, and Cumulative Index to Nursing and Allied Health Literature CINAHL). The outcomes of interest were (sub)acute (ie, within 3 months after surgery) and chronic (>3 months after surgery) pain and disability. After screening, 21 studies were included in the final analyses. It was found that psychological interventions significantly reduced (sub)acute pain (d = -0.26, 95% confidence interval CI -0.48 to -0.04) and disability (d = -0.43, 95% CI -0.84 to -0.03) as well as CPSP (d = -0.33, 95% CI -0.61 to -0.06) and disability (d = -0.43, 95% CI -0.68 to -0.18). In addition, interventions delivered after surgery and interventions delivered by a psychologist tended to be more effective than interventions delivered before surgery and interventions delivered by another healthcare provider. Furthermore, the current review points to the need for more research to determine which specific type of intervention may be most beneficial for surgical patients. Finally, the current review identified that research in this domain has concerns regarding bias in missing outcome data due to withdrawal and drop out.
