Methodology for Proper Clinical Validation of Artificial Intelligence Technology for Medical Diagnosis and Prediction

Artificial intelligence (AI) is projected to substantially influence clinical practice in the foreseeable future, especially in areas of diagnosis, risk assessment, and prognostication through predictive algorithms. However, despite the excitement around the technologies, it is yet rare to see examples of robust clinical validation of these clinical applications and, as a result, very few are currently in clinical use. Thorough, systematic validation of AI technologies using adequately designed clinical research studies before their integration into clinical practice is critical to ensure patient benefit and safety while avoiding any inadvertent harms. The use of external data unused for algorithm development, collected in a manner that minimizes spectrum bias ideally from multiple institutions, is crucial for proper validation of the clinical performance of an AI algorithm for medical diagnosis and prediction. The ultimate clinical validation requires a demonstration of the value of an AI system through positive impact on patient outcomes, beyond performance metrics.
