Patterns for building Electronic Medical Record (EMR) and Electronic Health Record (EHR) systems. Prioritizes patient safety, clinical accuracy, and practitioner efficiency. Every design decision must be evaluated against: "Could this harm a patient?" Clinical encounters should flow vertically on a single page — no tab switching: Red flags in any template must trigger a visible, non-dismissable alert — NOT a toast notification. Critical interactions block prescribing by default . The clinician must explicitly override with a documented reason stored in the audit trail. The system never silently allows a critical interaction. Once a clinical encounter is signed: Vitals Display: Current values with normal range highlighting (green/yellow/red), trend arrows vs previous, clinical scoring auto-calculated (NEWS2, qSOFA), escalation guidance inline. Lab Results Display: Normal range highlighting, previous value comparison, critical values with non-dismissable alert, collection/analysis timestamps, pending orders with expected turnaround.
