About Bedside Diagnostic Challenge:
Except for Hospitalists, Emergency Medicine physicians, and Interventional Cardiologists, most internists will spend the bulk of their professional time with patients in an office setting.
Here is where finely tuned clinical skills are most important in leading to accurate diagnoses, fewer complications resulting from unnecessary tests and procedures, and lower costs. Med Challenger Bedside Diagnostic Challenge reinforces the value of these clinical skills and tests users on their knowledge of them.
Bedside Diagnostic Challenge questions are issued periodically every month as a free content benefit of Med-Challenger.
