Our Aim - Driving Best Practice

• Key improvement messages

• Demonstrated using simulation

• Uses default data for immediate testing

• Local hospital data can be uploaded


Answering Questions

• What is my bed occupancy %?

• How many beds am I using?

• What are my wait times for beds?

• How do improvement scenarios impact on these results?


Simulation Model


Parameter 1 - Admissions


Parameter 2 – Length of StayNumber of midnight stays by hour and day of the week


Parameter 3 – Discharge profile


Parameter 4 - Beds


Improvement Scenario 1

What if GP referrals arrived earlier in the day?



What if our ambulatory care patients were treated elsewhere?

•Select a percentage of

admissions classed as

“ambulatory” (default 25%)

•Select likely impact on number

of midnight stays



Patients who stay for less than 2 midnights

•Research suggests 65% of patients


Move patient discharges forward to earlier in the day




Reduce 14 night length of stay for over 75s


Which scenario has the most impact?

1. GP referrals earlier?

2. Ambulatory care treated elsewhere? (25% of admissions)

3. Increase proportion of stays that are less than 2 midnights?

4. Move 50% of discharges earlier in the day?

5. Reduce 14 night stays for over 75s? (25% of admissions)


Results are in…

Which would you implement first?


7 Day Working – Current Question

• How to model this?

• Staff available 7 days a week to make discharge decisions

• Use a Monday profile (furthest from the weekend)

• What would you expect to see?


7 Day Working – Current Question

Actually increases capacity required


Why?

Looking at 0-7 midnight stays – around 75% of admissions


Impact of the weekend

Number of midnight

stays appear to be

driven by a push to

discharge on Friday


7 day compared to Monday profile

• Patients are more likely to be discharged at the weekend• Have a longer length of stay during the week

Midnight stays 7 day profile Monday only

What next?

• Currently being tested with 3 hospitals for usability

• Presenting a poster at 7 Day Working event November 16th


Continuing the Work

• More questions emerging

• Informing national debate on emergency care and 7 day working

• Disseminate to hospitals

• Seeking support

• Link with research interests?
