Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to determine if a simple intervention to improve hand hygiene, consisting of a 3-4 minute training video, on-site posters, and hand hygiene supplies, can reduce respiratory and GI illness among employees.

Detailed Description
-----------------
The purpose of this study is to determine if a simple random cluster intervention trial to improve hand hygiene, consisting of a 3-4 minute training video, on-site posters, and hand hygiene supplies, can reduce respiratory and GI illness among those in the intervention group compared to the control group. The intervention was performed among employees in a Midwestern public government setting. Employees in the treatment group received a 3-4 minute training video online that was embedded in the baseline survey. Motivational posters from the USDHHS encouraging proper hand hygiene were installed in the workplace, along with hand hygiene supplies. The control group received a program called Ask Me 3 developed by the National Patient Safety Foundation; the intervention consisted of a 3-4 minute training video to encourage clear communication with their health care providers, a brochure discussing the Ask Me 3 principles of clear communication with health care providers, and a key-ring with the Ask Me 3 communication principles to promote more effective communication with health care providers at visits out side of work. The groups were followed monthly through surveys over the Internet for an average of three months after baseline to determine if a relative reduction in self-reported respiratory / GI infections occurred in the intervention group compared to the control group.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Relative reduction in self-reported respiratory and gastrointestinal infections | Monthly surveys elicited information among employees in both the intervention and the control group about self-reported usual hand hygiene practices, symptoms of respiratory and GI infections and missed work days due to these symptoms during the prior 30 days. After the close of the study, statistical analysis was conducted to determine relative reductions in the intervention group compared to the control group regarding: self-reported infections and work days missed due to such infections. | prior 30 days as elicited by self-report on four monthly surveys | 
| Self-reported missed days of work due to symptoms of respiratory and gastrointestinal (GI) infections | Monthly surveys were administered over the Internet for an average of three months to determine if a relative reduction occurred in the intervention group compared to the control group in self-reported missed days from work due to symptoms of respiratory or GI infections. | Monthly surveys for an average of three months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Self-reported usual daily hand hygiene behaviors | Monthly surveys were administered for an average of three months to determine if a relative improvement from self-reported hand hygiene behaviors was seen in the intervention group compared to the control group, from baseline information. | Monthly self-report surveys for an average of three months from baseline |
