Design and Evaluation of a Hand Hygiene Prompting System for Private Residences
Bibliographic record
Abstract
Hand hygiene can prevent the spread of infection, but it is often overlooked in the community. The objective of this project was to develop and evaluate a hand hygiene prompting system for use at the entrance of private residences. The system included passive infrared sensors, a buzzer, and a light emitting diode connected to a microcontroller that was programed to prompt individuals to wash their hands using an attached alcohol gel dispenser as they entered their residences. The system was evaluated over 4 weeks in 20 households (10 control and 10 intervention). There was an increase in hand hygiene adherence (41.7% to 92.5%, p < 0.0001) for the intervention group in Week 2 when prompting was activated, followed by a decrease in Week 3 after prompting was deactivated (92.5% to 44.8%, p < 0.0001) while no change was seen for the control group (p = 0.789). Key words: Hand hygiene, prompting, infection control, smart home, biometrics

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
