Empowering Physicians With Evidence-Based Decision Support for Pediatric Rheumatology

Study Overview
=================
Brief Summary
-----------------
This study compares the ability of clinicians to make diagnoses with or without the assistance of diagnostic decision support software. The area of clinical focus is primarily rheumatology.

Detailed Description
-----------------
The study uses written case vignettes, not decisions about patients seeking care from the study subjects (i.e., clinicians).

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Other: Diagnosis<br>Test diagnostic decision support software | Other: Diagnosis<br>* Unaided: The testers will record a differential diagnosis consisting of a list of diseases and their ranking and a prioritized list of test orders, as well as the most appropriate referral for further evaluation and treatment of the patient. Aided: Then testers will enter the case into diagnostic decision support software and after getting advice from the software, the testers will record the same information as in Unaided, but allowing for the possibility that responses could differ as a result of using the software.<br>|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Measures of Diagnostic effectiveness | Each clinician subject reviews each case vignette and lists their differential diagnosis (Unaided). Then the clinician subject uses the diagnostic decision support software and then lists a revised differential diagnosis (Aided). The match between the clinician subject's differential diagnosis and a Gold Standard differential diagnosis list for each case is measured, looking at rank order of correct diseases and omissions. | Completion of each case vignette (typically ½ hour) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Measures of Patient workup effectiveness | Each clinician subject reviews each case vignette and lists their initial workup (Unaided). Then the clinician subject uses the diagnostic decision support software and then lists a revised initial workup (Aided). The match between the clinician subject's initial workup and a Gold Standard workup list for each case is measured, looking at rank order of correct diseases and omissions. | Completion of each case vignette (typically in the same ½ hour as measure 1) |
