  • Data collection programme, presence of a hospital-based stroke data collection programme at baseline; indicator at baseline, hospital-level passing rate for each indicator at baseline are shown.

  • Active-I, active-implementation; DVT, deep vein thrombosis; NIHSS, NIH Stroke Scale score at admission; post-I, post-implementation; pre-I, pre-implementation.
