Overview
Evaluate preoperative laboratory readiness for a scheduled surgical procedure. Determine required labs based on procedure type (low/medium/high risk), patient comorbidities, ASA physical status classification, and current medications. Query existing Observation resources to identify which required labs are already available within acceptable timeframes. Generate ServiceRequest resources for missing labs. Assess anticoagulation status and bridging needs.
