Evaluation of Risk-Based Predictive Models to Inform the Efficiency of Perioperative Systems

We previously developed an automated electronic health record-based risk stratification tool, called the Comorbidity Assessment and Surgical Triage (CAST) score, which we implemented in KP HealthConnect to improve triage of elective surgical patients to perioperative medicine clinic visit types in real-time. This project seeks to improve the efficiency of operative workflows by evaluating the impact of CAST implementation on pre-operative workflows and surgical outcomes; characterizing patients with discordant risk assessments between CAST and the clinician; and evaluating the association between CAST and operative resources, including surgical case duration.
