Abstract

Objectives: This study aimed to establish whether hypothermia was present in patients who required a blood transfusion and underwent a urology procedure, as well as identify staff knowledge and understanding.

Patients and methods: A staff survey was conducted with respondents from a range of clinical settings, with some staff working across more than one area. A retrospective review of 46 medical records was conducted between January 2021 and July 2022. All data were exported into an Excel spreadsheet and analysed.

Results: Staff (70%) were unaware of guidelines informing thermoregulation practices; however, 90% understood the importance of normothermia in the perioperative environment. Medical record review demonstrated temperature monitoring and intervention implementation varied across the perioperative journey, with 20% of patients hypothermic on admission and 89% of the cohort having two or more risk factors.

Conclusion: There is no formal process for the management of inadvertent perioperative hypothermia throughout the patient journey at the hospital. A variety of intrinsic factors (age, patient comorbidities, American Society of Anaesthesiologists score) and external factors (patient waiting times, anaesthetic modality, type of procedure, environmental influences), impact each patient's risk of inadvertent perioperative hypothermia.
