Development and validation of a multivariable prediction model for early prediction of chronic postsurgical pain in adults: a prospective cohort study. Comment on Br J Anaesth 2022; 129: 407–15

Editor—van Driel and colleagues1 developed and validated a prediction model for chronic postsurgical pain (CPSP) in adults. The rationale for the use of predictive modelling in clinical risk scenarios is compelling, and the authors developed a model with four items that are readily available in clinical practice, which is a welcome advance. Despite the clinical relevance of the topic and the rigorous study design, certain issues require clarification.
