Potential confounding variables, including total number presentations, occupancy, staffing levels triage category distribution, also collected. MAIN OUTCOME MEASURES Waiting time patients; waiting time, treatment discharged ED; proportion who did not wait be seen by doctor (DNW rate); ambulance offload times longer than 30 minutes. RESULTS We found reduction respect KPIs system. There increases (median, 40 min v 78 min), 49 87 128 147 min) 214 280 ED. DNW rate (8.3% 15.6%) minutes (10.5% 13.3%). All differences statistically significant (P < 0.05). CONCLUSION Implementation deterioration KPIs.
