COVID-19 Related Health and Infection Control Practices Among Dentists

Study Overview
=================
Brief Summary
-----------------
As dentists begin reopening their practices during a global pandemic, the risk of COVID-19 infection that dentists 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. The goal of the proposed study is to understand U.S.-based dentists' health and dental-practice reactions to COVID-19. To estimate this, U.S-based dentists will be surveyed monthly. These findings could be used to describe the prevalence and incidence of COVID-19 among dentists, determine what infection control steps dentists take over time, and estimate whether infection control adherence in dental practice is related to COVID-19 incidence.

Eligibility Criteria
-----------------
Inclusion Criteria: Primary dental practice is in United States 18 years of age or older Dentist Exclusion Criteria: •Answered no to ADA survey sent May 2020 that read As part of ongoing efforts to monitor the effect of COVID-19 on the dental team, the ADA is interested in collecting data related to infection rates. Would you also be willing to participate in a separate, longitudinal study that would require you to report whether you or your staff have exhibited symptoms of COVID-19, and whether you have been tested or diagnosed? The study would be anonymous and under IRB protocols.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| COVID-19 probable or confirmed case | COVID-19 case as confirmed by clinician and/or detection of SARS-CoV-2 RNA or a specific antigen in a clinical specimen | 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 | 
| Dentists' use of personal protective equipment | Self-reports of personal protective equipment use | 12 months |
