Evaluation of Store-and-Forward Teledermatology Versus a Face-to-Face Assessment During a Skin Cancer Screening Event

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to determine the diagnostic and management concordance of face-to-face dermatologist versus a store-and-forward teledermatologist at a skin cancer screening event. The investigators' hypotheses include the following: Compared to in-person assessment, store-and-forward teledermatology assessment will result in adequate diagnostic concordance. Compared to in-person assessment, store-and-forward teledermatology results in adequate management concordance. The sensitivity and specificity of store-and-forward evaluation to detecting lesions that are either premalignant or malignant will be similar to that of in-person evaluation.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Aggregated diagnostic concordance | Aggregated diagnostic concordance which is defined as the agreement of the in-person dermatologist's principle diagnosis with the teledermatologist's primary diagnosis or any of the differential diagnoses. | At the time of dermatologist evaluation (Day 1) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Primary diagnostic concordance | Diagnostic concordance between the in-person dermatologist and the teledermatologist for their primary diagnosis. | At the time of dermatologist evaluation (Day 1) | 
| Categorical diagnostic concordance | Diagnostic concordance between the in-person dermatologist and teledermatologist based on standard clinical diagnostic categories for each lesion. | At the time of dermatologist evaluation (Day 1) | 
| Management concordance | The concordance between the in-person dermatologist and teledermatologist for the chosen management plan for each lesion. | At the time of dermatologist evaluation (Day 1) | 
| Sensitivity | The sensitivity of store-and-forward evaluation to detecting lesions that are either premalignant or malignant. | At the time of dermatologist evaluation (Day 1) | 
| Specificity | The specificity of store-and-forward evaluation to detecting lesions that are either premalignant or malignant. | At the time of dermatologist evaluation (Day 1) |
