Brief Summary

This investigation is a randomized intervention trial that evaluates behavioral nudges (BN) to increase hand washing behavior and subsequently reduce COVID-19 spreading to a targeted high-risk patient population based in Wisconsin.

Arm && Interventions

Group	Intervention	Description
Anchoring	Nudge	Involves once again providing "default access" to HW materials as above, but adds an explicit written cue to wash hands at a rate of (15) times per day, which is placed directly on the soap dispenser. The stimulus is intended to deliberately prime participant thinking (and subsequent behavior) towards a higher reference point that "overshoots" a desired target rate of 10+ daily HWs.
Inertia	Nudge	Participants simply receive and subsequently have "default" access (i.e., readily and immediately available) to handwashing (HW) materials. This condition will functionally serve as a control comparison. As the term implies, inertia capitalizes on minimizing effort necessary (e.g., going to the grocery store) to engage in HW behavior in one's personal environment.

Primary Outcome Measures

Name	Time	Method
Hand Washing Behavior	8 weeks post-enrollment	Measured via adapted version of a previously validated questionnaire (Hygiene Inventory - 23), which specifically includes (a) 1 item about approximate hand washing frequency on an average day, with response options of whole numbers from 0-29 and an additional option of "30 or more" where higher numbers are generally considered better outcomes, (b) 10 items about hand washing behavior in various contexts, with response options of "1 - Never", "2 - Occasionally", "3 - Usually", and "4 - Always" where higher scores are considered better outcomes, and (c) 1 item about general hand hygiene using antibacterial gel or wipes, with response options of "1 - Never", "2 - Occasionally", "3 - Usually", and "4 - Always" where higher scores are considered better outcomes.

Secondary Outcome Measures

Name	Time	Method
Clinical Outcomes - Surgery	12 weeks post-enrollment	Patient frequency/rate for the following variables measured via electronic medical record: Respiratory Illness at time of surgery Pre-Operative COVID19 testing Surgery delayed due to respiratory illness Surgery delayed due to COVID19 positive Adverse outcome secondary to delay in surgery Post operative intubation \>2 days Post operative unplanned reintubation Post operative pneumonia Post operative respiratory illness secondary to COVID19
Clinical Outcomes - Obstetrics & Gynecology	12 weeks post-enrollment	Patient frequency/rate for the following variables measured via electronic medical record: Respiratory Illness at time of Delivery Pre-delivery COVID19 testing Delivery plan altered due to respiratory illness Miscarriage Preterm labor/birth Preeclampsia Respiratory Illness in newborn Newborn COVID19 testing
Clinical Outcomes - General/Internal Medicine	12 weeks post-enrollment	Patient frequency/rate for the following variables measured via electronic medical record: ED visit (respiratory illness/other) ED visit reason (if non-respiratory) Admission (respiratory Illness) Respiratory Illness secondary to COVID19 ICU admission due to respiratory illness ICU admission due to COVID19 Mechanical Respiratory support Duration of Mechanical support (days) Mortality (respiratory Illness/other)
