Registered outcomes4
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Amount of Bacterial contamination between mask up/off or dangling | Hour 2 | Bacterial contamination is measured as quantitative bacterial burden, measured as colony-forming units (CFUs), recovered from cultures collected from the inner and outer surfaces of surgical masks before and after the standardized 2-hour observation period. |
| Secondary | CFU counts recovered from additional sampling sites | Hour 2 | CFU counts recovered from additional sampling sites, including the neck skin, dominant hand, and anterior chest region of the scrub top |
| Secondary | Changes in CFU counts between baseline and post-observation | Hour 2 | Changes in CFU counts between baseline and post-observation at each sampling site. |
| Secondary | Differences in bacterial loads at different culture sites | Hour 2 | Patterns of bacterial distribution across sampling locations that may provide insight into potential contamination pathways - differences in bacterial loads and or species at different culture sites - Variations in the counts may provide insights into mechanisms of possible contamination based on mask wearing practice style |
