Abstract
Purpose
The purpose of this study was to investigate associations between postoperative delirium
(POD) and unplanned perioperative hypothermia (UPH) among adults undergoing noncardiac
surgery.
Design
A retrospective, exploratory design was used.
Methods
A retrospective, exploratory study was conducted using electronic medical record data
abstracted from a purposive convenience sample of adult patients undergoing noncardiac
surgery from January 2014 to June 2017.
Findings
The analyzed data set included 22,548 surgeries, of which 9% experienced POD. Logistic
regression indicated that American Society of Anesthesiologists (ASA) class was the
strongest predictor of POD (χ2 = 1,207.11, df = 4, inclusive of all ASA class terms). A significant relationship between UPH and
POD (χ2 = 54.94, df = 4, inclusive of all UPH terms) and a complex relationship among UPH, patient age,
ASA class, and POD were also found.
Conclusions
Results support a relationship between UPH and POD. Notably, there is also a complex
relationship in the noncardiac surgery population among UPH, age, ASA class, and POD.
Preliminary understanding of this relationship is based on the pathophysiological
response to surgical stress. Further research is indicated.

- Assessing Relationship of Postoperative Delirium and Unplanned Perioperative Hypothermia in Surgical PatientsJournal of PeriAnesthesia NursingVol. 36Issue 6
- PreviewWith a great interest we read the recent article by Wagner et al1 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,2 their findings have potential implications.
