Bays A&E
What is an A&E bay?¶
An A&E bay is a treatment space within the Emergency Department used to assess and manage lower-acuity patients requiring ambulatory or chair-based care, typically within the minor injury or illness pathway.
Capacity outputs¶
- ADULT_MINOR_AE_BAYS
- CHILD_MINOR_AE_BAYS
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). Minors are defined with: Acuity IN {3,4,5}. Null or unknown acuity values are assumed to belong to the minor pathway.
| Level | Description |
|---|---|
| 1 | Immediate care level |
| 2 | Very urgent level |
| 3 | Urgent level |
| 4 | Standard level |
| 5 | Low acuity level |
| Subgroup | Classification IDs |
|---|---|
| adult minor | CLASS_AE, CLASS_AGE_ADULT, CLASS_AE_MINOR |
| child minor | CLASS_AE, CLASS_AGE_CHILD, CLASS_AE_MINOR |
Workload derivation¶
Primary workload object: occupancy hours
\[\text{occupancy hours} = \text{attendances} \times \frac{\text{LOS minutes}} {60}\]
Capacity conversion¶
\[\text{required AE bays} = \frac{\text{occupancy hours}}{\text{annual operational hours} \times \text{utilisation}}\]
Assumptions¶
| Subgroup | Assumption | Category | Assumption ID |
|---|---|---|---|
| adult minor | LOS | workload | AE_ADULT_MINOR_LOS |
| adult minor | utilisation | operational | AE_ADULT_MINOR_UTIL |
| child minor | LOS | workload | AE_CHILD_MINOR_LOS |
| child minor | utilisation | operational | AE_CHILD_MINOR_UTIL |
| all groups | annual operational hours | operational | AE_BAYS_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.
