Use of thermal imaging to measure the quality of hand hygiene.

OBJECTIVES: Hand hygiene has long been promoted as the most effective way to prevent the transmission of infection. However, due to low compliance and low quality of hand hygiene reported in previous studies, constant monitoring of hand hygiene compliance and quality among healthcare workers is crucial. This study investigated the feasibility of using a thermal camera with an RGB camera to detect hand coverage of alcohol-based formulation, thereby monitoring the quality of hand rubbing. METHODS: In total, 32 participants were recruited to participate in this study. Participants were required to perform four types of hand rubbing to achieve different coverage of the alcohol-based formulation. After each task, participants' hands were photographed under a thermal camera and an RGB camera, while an ultraviolet (UV) test was used to provide the ground truth of hand coverage of alcohol-based formulation. U-Net was used to segment areas exposed to alcohol-based formulation from thermal images, and system performance was evaluated by comparing differences in coverage between thermal images and UV images in terms of accuracy and Dice coefficient. RESULTS: This system found promising results in terms of accuracy (93.5%) and Dice coefficient (87.1%) when observations took place 10 s after hand rubbing. At 60 s after hand rubbing, accuracy and Dice coefficient were 92.4% and 85.7%. CONCLUSIONS: Thermal imaging has potential for accurate, constant and systematic monitoring of the quality of hand hygiene.

[Autopsies in Switzerland, Germany and Austria: considerations about legal facts and the current situation]. / Obduktionen in der Schweiz, Deutschland und Österreich: Rechtliche und rechtstatsächliche Untersuchungen.

Significant reasons militate for the implementation of clinical autopsies: On the part of physicians and nurses, there is quality assurance, establishment of legal certainty regarding possible accusations of medical errors and development of treatment methods. On the part of patients and their relatives, there is consolation and relief in cases of unexpected death, insight into genetic dispositions and insurance law concerns, to name only a few. However, a continuing decrease of clinical autopsies can be observed in Switzerland, Germany and Austria. The thesis asserting that the often required informed consent of the deceased during his/her lifetime or of close relatives is a crucial reason for this decrease needs to be called into question due to recent studies. Mainsprings are rather structural reasons, such as the often deficient communication with the patient or close relatives, economic reasons, namely the frequently insufficient remuneration for the clinical autopsy, organizational causes, in particular the repeatedly encountered suboptimal collaboration between the individual departments and the pathology department, the high administrative effort and probably the decreasing appreciation of the clinical autopsy.
