NEAT falls from 78% to 64%. A run chart shows six consecutive points below the median. Interpret using Donabedian language and outline a PDSA response.

Donabedian: structure → process (NEAT, door-to-doctor) → outcome (mortality, revisit).[5] Six-point shift = special-cause variation — investigate assignable causes, especially access block/boarding (output).[4][1] PDSA: plan aim/measure/written prediction; do small test; study against run chart; act adopt/adapt/abandon.[3] Avoid tampering and gaming the 4-hour clock — four-hour pressure carried quality-and-safety costs even where flow improved.[4][6]
