  • EDBT, emergency department boarding time; EDTAO, emergency department time to admission order.

  • p Values were calculated by the two-sample Wilcoxon rank-sum test.

  • * p≤0.001 for the comparison with the baseline period.

  • Study phases are as follows: baseline 23 May to 30 June 2007; phase 1: 1 July to 30 September 2007; phase 2: 1 October to 31 December 2007; phase 3: 1 January to 31 March 2008; phase 4: 1 April to 30 June 2008.

  • EDTAO represents the time from decision to admit and admission or transitional orders received; EDBT represents the time from decision to admit to departure from the emergency department.

  • § Patients whose destination was the general medicine ward without a telemetry monitoring designation.
