NHS A&E Performance Dashboard

This project analyses A&E attendances and 4-hour delay performance across NHS England.
It combines demand analysis with performance metrics to identify patterns in service utilisation and waiting times.

Key elements:

  • Comparison of walk-in vs booked attendance pathways
  • Analysis of A&E types (Type 1, Type 2, Other)
  • Normalised delay metrics for fair comparison
  • Interactive dashboards with region and season filters
