Beds A&E
What is an AE bed?¶
An A&E bed is a trolley-based treatment space within the Emergency Department used to assess, monitor and manage patients requiring higher-acuity or more prolonged emergency care.
Capacity outputs¶
- ADULT_MAJOR_AE_BEDS
- CHILD_MAJOR_AE_BEDS
- RESUS_AE_BEDS
Conversion archetype¶
- flow-space occupancy — FRM_FLOW_SPACE
Operational constraint¶
- Concurrent occupancy over operational periods
Activity classification logic¶
Department type 01 only (consultant-led 24/7 with full resuscitation facilities). Majors are defined with: Acuity = 2. Resuscitation cases are defined with: Acuity = 1.
| Level | Description |
|---|---|
| 1 | Immediate care level |
| 2 | Very urgent level |
| 3 | Urgent level |
| 4 | Standard level |
| 5 | Low acuity level |
| Subgroup | Classification IDs |
|---|---|
| adult major | CLASS_AE, CLASS_AGE_ADULT, CLASS_AE_MAJOR |
| child major | CLASS_AE, CLASS_AGE_CHILD, CLASS_AE_MAJOR |
| resus | CLASS_AE, CLASS_AE_RESUS |
Workload derivation¶
Primary workload object: occupancy hours
\[\text{occupancy hours} = \text{attendances} \times \frac{\text{LOS minutes}} {60}\]
Capacity conversion¶
\[\text{required A&E beds} = \frac{\text{occupancy hours}} {\text{annual operational hours} \times \text{utilisation}}\]
Assumptions¶
| Subgroup | Assumption | Category | Assumption ID |
|---|---|---|---|
| adult major | LOS | workload | AE_ADULT_MAJOR_LOS |
| adult major | utilisation | operational | AE_ADULT_MAJOR_UTIL |
| child major | LOS | workload | AE_CHILD_MAJOR_LOS |
| child major | utilisation | operational | AE_CHILD_MAJOR_UTIL |
| resuscitation | LOS | workload | AE_RESUS_LOS |
| resuscitation | utilisation | operational | AE_RESUS_UTIL |
| all groups | annual operational hours | operational | AE_BEDS_ANNUAL_OPERATIONAL_HOURS |
Known issues / limitations¶
- Type 02 mono-specialty A&E out-of-scope in current development plan.
Dependencies¶
- No dependencies.
Future enhancements¶
- Obvious candidate for queueing methods.
