- Abstract:
- This study aimed to evaluate whether continuous axillary temperature monitoring using a wearable patch enables earlier detection of postoperative infections compared to conventional intermittent infrared thermometry. 103 surgical patients were included in this prospective, single-center study and monitored over an 11-month period. Continuous axillary temperature monitoring using the SteadyTemp® patch was compared to routine infrared measurements performed as part of clinical routine. The primary outcome was fever detection rate (≥ 38.0 °C). Secondary outcomes included the correlation between fever detection and laboratory values as well as the frequency of clinical interventions. Out of 103 included patients, fever was detected in 33 cases. Continuous monitoring identified fever in 31 of these 33 patients (93.9%), whereas infrared thermometry detected fever in only 12 cases (36.4%). In 16 cases where antibiotic therapy was initiated or adjusted due to newly detected fever, the patch detected fever in 15 patients, compared to only 7 detections by infrared thermometry. Surgical interventions due to suspected infections were performed in 5 patients, and fever was detected by the patch in all cases, while infrared thermometry detected fever in only 2 of these patients. Due to the frequent failure of infrared thermometry to detect fever, a scoring system was developed to assess the clinical relevance of fever detection. Continuous temperature monitoring with the SteadyTemp® patch demonstrated superior fever detection compared to infrared thermometry, leading to earlier identification of febrile events. This study suggests that continuous temperature monitoring may enhance infection surveillance in surgical patients, allowing for more timely clinical interventions.
