Preoperative Anxiety and Catastrophizing

Anxiety and pain catastrophizing predict acute postoperative pain. However, it is not well established whether they also predict chronic postsurgical pain (CPSP). The aim of this systematic review and meta-analysis was to investigate whether high levels of preoperative anxiety or pain catastrophizing are associated with an increased risk of CPSP.

Electronic search databases included PubMed and PsychINFO. Additional literature was obtained by reference tracking and expert consultation. Studies from 1958 until October 2010, investigating the association between preoperative anxiety or pain catastrophizing and CPSP in adult surgery patients, were assessed. The primary outcome was the presence of pain at least 3 months postoperatively.
