Objectives: (i) To demonstrate the feasibility of automated, direct observation and collection of hand hygiene data, (ii) to develop computer visual methods capable of reporting compliance with moment 1 (the performance of hand hygiene before touching a patient) and (iii) to report the diagnostic accuracy of automated, direct observation of moment 1.
Design: Observation of simulated hand hygiene encounters between a healthcare worker and a patient.
Setting: Computer laboratory in a university.
Participants: Healthy volunteers.
Main Outcome Measures: Sensitivity and specificity of automatic detection of the first moment of hand hygiene.
Methods: We captured video and depth images using a Kinect camera and developed computer visual methods to automatically detect the use of alcohol-based hand rub (ABHR), rubbing together of hands and subsequent contact of the patient by the healthcare worker using depth imagery.
Results: We acquired images from 18 different simulated hand hygiene encounters where the healthcare worker complied with the first moment of hand hygiene, and 8 encounters where they did not. The diagnostic accuracy of determining that ABHR was dispensed and that the patient was touched was excellent (sensitivity 100%, specificity 100%). The diagnostic accuracy of determining that the hands were rubbed together after dispensing ABHR was good (sensitivity 83%, specificity 88%).
Conclusions: We have demonstrated that it is possible to automate the direct observation of hand hygiene performance in a simulated clinical setting. We used cheap, widely available consumer technology and depth imagery which potentially increases clinical application and decreases privacy concerns.

Background: The escalating threat of multidrug-resistant organisms (MDROs) in intensive care unit (ICU) demands innovative management strategies to curb the rising infection rates and associated clinical challenges.
Objective: To assess the effectiveness of integrating the multidisciplinary team (MDT) approach with the SHEL (Software, Hardware, Environment, Liveware) model in reducing MDRO infections within ICU settings.
Methods: From January 2021 to April 2024, a prospective, randomized controlled study was conducted in the ICU of Nantong Fourth People's Hospital, enrolling 411 patients with MDRO infections.

This study aimed to estimate the quantity and trends of salt intake from industrial fermented dairy products, develop strategies to reduce salt content, and inform policymakers on promoting public health through healthier dairy options. A cross-sectional study was conducted on fermented dairy products. Seventy-nine random samples were selected, and the salt (NaCl %) content was determined by potentiometric titration after sample preparation and homogenization; also samples were analyzed for their moisture (oven drying method).

Objective: Hand washing is considered an important public health intervention to reduce the burden of communicable diseases such as gastrointestinal and respiratory tract infections. Washbasins in public restrooms are often only equipped with cold water and it can be observed that people only rinse their hands briefly after using the toilet instead of washing them properly with soap. As there are no recommendations on the optimal water temperature for efficacy, we measured the efficacy of simple hand rinsing with cold (4°C) and warm (40°C) water for 10 and 20 seconds compared to the European Norm EN 1499 reference hand wash.

Background: We aimed to determine the household distribution and viability of Chlamydia trachomatis (Ct) from the eyes, face, and hands during the initial two visits of a year-long fortnightly cohort study in geographically defined adjacent households.
Methods/findings: We enrolled 298 individuals from 68 neighbouring households in Shashemene Woreda, Oromia, Ethiopia. All individuals above 2 years of age residing in these households were examined for signs of trachoma.
