DAW Analysis
DAW (Dispense as Written) analysis identifies prescriptions where the prescriber has specified brand-only dispensing. DAW-1 (prescriber-requested brand) and DAW-2 (patient-requested brand) are the most common DAW codes. High DAW rates indicate opportunities for prescriber education and member communication about generic equivalence.
