Aims and objectives: This study aims to explore the influence of using warming coats on patients’ feelings of cold and anxiety in the waiting area of a surgery ward. Background: Alleviating feelings of cold and anxiety in patients in waiting areas of surgery wards is a very important issue in nursing. Prior to a surgery, keeping warm can not only control patients’ body temperatures, but also make them more comfortable. Therefore, patients’ temperature control is an important task for surgery teams. Design: This study is a quasi-experiment study. Methods: This study of 60 patients divided into two groups: 30 people in the experimental group (given a heated coat) and 30 in the control group (using the regular method). After collecting the data of the varying degrees of patients’ feelings cold and anxiety from the pre-test, five minutes after intervention and ten minutes after intervention, we analyze the differences based on the Generalized Estimating Equation (GEE). Results: Compared with the control groups, decreases in cold feeling (p<.001) and anxiety (p=.002) were clearly observed in the experimental group in the waiting area at 5 minutes after intervention. Conclusions: The patients’ cold feeling and anxiety were reduced at 5 minutes when the patients were provided with a warm-keeping method in the waiting area of a surgery ward. Relevance to clinical practice: Based on results showing reduced degrees of cold feeling and anxiety in patients, this study shows that it would be beneficial to provide nursing staffs with warming facilities to give to patients.
