Episode 14: UTICalc with Nader Shaikh

Calculators, Emergency Medicine, Infectious Disease, Uncategorized

On this episode, host Jason Woods speaks to Dr. Nader Shaikh about his recent paper on the development of a calculator (UTICalc) to estimate the probability of UTI in pediatric patients. The calculator itself is fantastic and easy to use (see link below) but the discussion centers on the methods behind the calculator. We dig into how these calculators are developed, how to determine if they are accurate/useful, and how to use them in clinical practice.
