1. ↓ (safe) avoidable hospital admission
↑ quality of short-stay patient care
↑ efficiency & cost-effectiveness with shortened ALOS
↑ safety of patients discharged from AED
Enhanced patient satisfaction 2. Buffer hospital adm thereby reducing workload of other
specialties during night & weekend, service surge, disaster
3. Cohorting patients with emotional, psychiatric, violent & drunk problems
4. Toxicologically expert management of drugged, poisoned, overdosed patients – service & subspecialty development
5. Core competency training of new generation of Emergency Physicians beyond the first few hours

Operation of EMW - “treat & review” Essential success factors
Bed capacity = 8-10% of daily A&E attendance Support & maximize EMW functions Dependent on case-mix, expertise, cross-specialty support
Targeted clinical conditions Low acuity & undifferentiated presentation Disturbed ± toxicology patients
Senior rounds/oversight, frequent rounds (3+/day) Protocol & guidelines-driven Fast track Dx work-up – CT (brain, thorax & abd), USG, OGD Expedited SOPD appt Hub
cross-specialty & multi-disciplinary collaboration Geriatricians, Psy, AH… Community care support
Direct transfer out to specialty wards Availability of sub-acute, rehab & convalescent beds / hospitals
![Page 56: Roles of Emergency Medicine Ward (EMW)€¦ · Emergency Medicine Ward Task Force (2006) Wait & ... 22.4 18.1 19.7 19.5 19.4 19.8 20.3 21.1 21.4 21.2 22.2 Adm rate (HA ave) ... PYN](https://reader031.fdocuments.us/reader031/viewer/2022022102/5bb5959e09d3f2f2678cb791/html5/thumbnails/56.jpg)
Way Forward Other specialty presentation
Paediatric short-stay
Surgical symptomatology
Align practice & cross-specialty collaboration
Integrated care plans development
Deliverables monitoring: Adm rate to EMW
transfer-out rate to other clinical specialties
ALOS
Re-attendance to A&E & re-adm rate
Morbidity & Mortality in EMW
Patient satisfaction
