Clinical Recommender System: Predicting Medical Specialty Diagnostic Choices with Neural Network Ensembles

Abstract: The growing demand for key healthcare resources such as clinical expertise and facilities has motivated the emergence of AI based decision support systems. We address the problem of predicting clinical workups for specialty referrals. As an alternative for manually-created clinical checklists, we propose a data-driven model that recommends the necessary set of diagnostic procedures based on the patients' most recent clinical record extracted from the Electronic Health Record (EHR). This has the potential to enable health systems expand timely access to initial medical specialty diagnostic workups for patients. The proposed approach is based on an ensemble of feed-forward neural networks and achieves significantly higher accuracy compared to the conventional clinical checklists.
