The Real Problem 🏥

Emergency Department Delays & Patient Lives

When patients wait for hospital beds:

  • Risk of harm increases significantly
  • ~25 preventable deaths/month in Bristol NHS due to waiting
  • Staff need early warning to prevent these delays

The Competition Challenge 📊

Predict hospital harm 10 days in advance

  • Using: Real hospital data from Bristol NHS
  • Goal: Give hospital managers early warning so they can take pre-emptive action
  • Data source: 24 months of real hospital records

Forecast Evaluation: Future 120-Days (example)

Note: Forecasts are generated once every 5 days, 24 times across 120 days.

Can Point Forecasts Capture Peak Dynamics?
