2 Motivation Overcrowding in Hospitals: an International Crisis ED admissions Elective surgery Increased wait times. Increased medical errors. Increased length of stay. Increased medical negligence claims. Increased walkouts. Ambulance diversion. Patient safety at risk. Unnecessary deaths. 2

3 Motivation The Magic Fixes 3

4 Capacity (Number of Beds) Occupancy (%) Motivation S. Khanna, J. Boyle, N. Good, and J. Lind, Unravelling relationships: Hospital occupancy levels, discharge timing and emergency department access block, Emergency Medicine Australasia, vol. 24, no. 5, pp , Capacity : Group 1 (> 900 Beds) Capacity : Group 2 (900 <= Beds >= 300) Capacity : Group 3 (< 300 Beds) Occupancy (March 2010 quarter) 140% 130% 120% 110% 100% % 80% % Choke Point A : increasing patient turnover Choke Point B : excess ED inflow Choke Point C : excess inpatient ward inflow % 50% 40% Analysis Period : 1st October 2007 to 31st March 2010 (913 days) 4

5 Motivation S. Khanna, J. Boyle, N. Good, and J. Lind, Unravelling relationships: Hospital occupancy levels, discharge timing and emergency department access block, Emergency Medicine Australasia, vol. 24, no. 5, pp , QLD Group 3 Hospital Chokepoints : A : 98% B : 102% C: 106% 5

8 Analysis Methodology Analysis period : 1 Oct 2007 to 31 March 2010 (913 days). Data Sources : Hospital Based Corporate Information System (HBCIS) Emergency Department Information System (EDIS) 3 points of performance change identified : Choke Point A : increasing patient turnover Choke Point B : excess ED inflow Choke Point C : excess inpatient ward inflow Compared to similarly sized QLD hospitals In Addition : Analysis groups : for all days together. for weekdays. for weekend days. 8

9 The findings Caboolture Hospital Chokepoints : 100%, 106%, and 113% QLD Group 3 Hospital Chokepoints : 98%, 102%, and 106% 9

10 The findings Weekdays Vs Weekends Caboolture Hospital WEEKDAY Chokepoints 100%, 108%, and 113% Caboolture Hospital WEEKEND Chokepoints Choke Point B : 106% 10

11 In Conclusion Do the science Know the your service Understand how the science applies to your service 11

12 Patient AEHRC Enabling hospitals to better manage their resources & hence reduce waiting times 12
