COVID-19-Related Health and Practices Among Dental Hygienists

Study Overview
=================
Brief Summary
-----------------
As dental practices reopen their practices during a global pandemic, the risk of 2019 novel coronavirus (COVID-19) infection that dental hygienists face in providing dental care remains unknown. Estimating the occupational risk of COVID-19, and producing evidence on the types of infection control practices and dental practices that may affect COVID-19 risk, is therefore imperative. These findings could be used to describe the prevalence and incidence of COVID-19 among dental hygienists, determine what infection control steps dental hygienists take over time, describe dental hygienists' employment during the COVID-19 pandemic, and estimate whether infection control adherence in dental practice is related to COVID-19 incidence.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| COVID-19 probable or confirmed case | 2019 novel coronavirus (COVID-19) case as confirmed by clinician and/or detection of SARS-CoV-2 antigen or antibody | 18 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Anxiety | Assessed using the Patient Health Questionnaire for Depression and Anxiety (PHQ-4). Two items scored 0 to 3 (total score of 0-6), with higher numbers indicating greater anxiety. | 12 months | 
| Depression | Assessed using the Patient Health Questionnaire for Depression and Anxiety (PHQ-4). Two items scored 0 to 3 (total score of 0-6), with higher numbers indicating greater depressive symptoms. | 12 months | 
| Dental practice infection control efforts | Self-reports of infection control efforts in the respondents' primary dental practices. | 12 months | 
| Personal protective equipment | Availability, frequency of use, and frequency of reuse of personal protective equipment | 12 months | 
| Employment status | Self-descriptions of current level of employment as a dental hygienist and reasons for non-employment. | 12 months |
