assessing the relationship of postoperative delirium (POD) and unplanned perioperative
hypothermia (UPH) in adult patients undergoing noncardiac surgery. They showed a significant
relationship between UPH and POD. Furthermore, there are complex relationships among
UPH, age, ASA physical status class and POD. Given that POD is significantly associated
with increased lengths of ICU and hospital stay, costs, morbidity and mortality after
noncardiac surgery,

their findings have potential implications. Other than limitations described by the
authors in discussion section, however, we noted several issues in this article on
which we invited the authors to comment.To read this article in full you will need to make a payment

- PreviewThank you for your letter regarding our publication. You make some interesting comments that are worthy of further clarification. You are correct in that the development of postoperative delirium (POD) is the consequence of many complex interactions among numerous predisposing and precipitating factors, all of which would be virtually impossible to account for in a single study. We would like to address the concerns that you have raised. The authors did address many of these complex interactions in the article, many of which were addressed in the study inclusion/exclusion criteria.
