Yang MMH, et al. - In adults undergoing inpatient surgery, researchers identified predictors of poor postoperative pain control via conducting a systematic review and meta-analysis. This research included 33 studies representing 53,362 patients. According to findings, nine predictors (ie, young age, female sex, smoking, history of depressive symptoms, history of anxiety symptoms, sleep difficulties, higher BMI, presence of preoperative pain and use of preoperative analgesia) have been identified for poor postoperative pain control. These should be recognized as potentially important factors in the development of discipline-specific clinical care pathways (eg, multimodal analgesic strategies and enhanced recovery after surgery programmes) to improve pain outcomes and guide future research on surgical pain.
