In the course of undergoing surgery, patients are exposed to several risks during the perioperative period, i.e. before, during and after the procedure (pre-, intra- and post-operative phase). One of the oldest and most common side effects of anaesthesia is that patients develop perioperative hypothermia, i.e. a body temperature below 36 °C. This can lead to complications such as increased blood loss, post-operative wound infections, chills and great discomfort from freezing. Since the 90s, there has been extensive medical research on what perioperative hypothermia is, what risks exist and how it can be avoided with heat-preserving aids, i.e. warm air blankets, blankets, shirts, warm liquids, electric blankets/mattresses.

However, research shows that adherence to the recommended heat-retaining aids is still low 5–67%. Which is due to several factors such as access to heat-retaining aids, lack of clear guidelines, financial warnings, communication - differences of opinion between the surgical team members, lack of knowledge, uncertainty about making mistakes, time pressure and culture in the workplace. Several of these factors refer to a lack of support from management and organization, which is why there is a need to explore the perspective of management and organization. Furthermore, research on the patient's experience of thermal comfort and dissatisfaction is poorly researched and needs to be studied further.
