A Practical Approach To Improving patient flow using The Theory of Constraints Oxford Radcliffe NHS Trust
Oxford Radcliffe Hospitals Trust • The Trust has nearly 1,500 beds • 400,000 people attended outpatients • 112,000 patients were admitted • 90,000 accident and emergency attendees • 7,000 babies were delivered. • Over 10,000 staff work in the organisation
What is The Theory of Constraints? Eliyahu Goldratt first used in industry - • Thinking Tool • Not a set of solutions • Focus for Change • Whole systems approach • Simple common sense steps
TOC Process = 5 Steps (Step 0 - Mapthe System) Step 1 - Identifythe Constraint Step 2 -Get the mostout of the constraint Step 3 - Supportthe systems constraint Step 4 - Elevatethe systems constraint Step 5 - Go backto step 1
Rate Limiting Step – Weakest Link Referral OPD Waiting list Pre – assessment surgery OPD 100 60 60 50 25 12
Types Of Constraint Find The rate limiting factor: • Physical bottleneck – a capacity limited resource • Thinking Constraint – ‘We’ve always done it like that’ • Policy Constraint – an organisational policy whether written or believed
Constraint V Bottleneck • Bottleneck: Any resource whose capacity is less than the demand placed upon it. • Constraint: Bottlenecks come and go. A constraint limits the whole systems performance over an extended period of time.
Benefits of Mapping • Gain Agreement on what is ‘Whole System’ • Identify True Constraint • Highlight queues & time span • Identify other bottlenecks/issues • Starting point for redesign • Step 5 – Cause & effect
TOC as a Generic Tool Principles may be applied to any whole System • Gynaecology • PND & Ultrasound • MaxilloFacial/ Orthodontics • Urology • Finance • Horton General Hospital
Case Study – Horton General • District general hospital = 240beds • 2000 –2001 Long Trolley Waits • High Cancellation of electives due to”no beds available”.
Introduction Of TOC • April 2001 – Capacity group formed • April 2001 – TOC Workshop for key stakeholders • May 2001 – System mapping and analysis
HGH – Identify the Constraint Medicine Discharge A&E Treatment PCT Surgery Social Care Waiting List Discharge+ Trauma & Ortho
5 Steps of TOC Step 1 – Identify the constraint = Nursed beds Step 2 –Get the most out of the constraint = 24hour stays, bed usage by A&E. Location of Day case patients
Step 2 – Get the most out of the constraint! • Not about working harder. • Constraint should only work on core role – otherwise capacity wasted. • Nursed beds – most appropriate use of bed stock & nursing activity • Starting point for analysis
Maximise Efficiency 24 hour or less time as IP Referrals into A&E A&E PCT Information Nursed beds Waiting List Inpatient or Day case
Information • 25% of admissions through A&E stayed 24 hours or less – of those: - 25% non specific chest pain - 18% self harm • Minimal day case activity found in inpatient areas. • PCT – A&E used appropriately by GP’s
Information V Anecdote • Many decisions about waiting times are based on anecdote not fact!
5 Steps • Step 3 Support the constraint New ways to offload the constraint. • Emergency transfer beds – existing area • Discharge Lounge – Old children's ward • Discharge ward
5 Steps of TOC • Step 4 – Elevate the constraint • Discharge Beds - increase in capacity • New build for Emergency transfer Beds • Step 5 – Go Back
Results so far…. • Trolley waits reduced • Over 80% of patients are admitted within 4 hours of decision to admit in A&E • Number of elective cancellations reduced.
Lessons Learnt • More efficient to “pull” patients through the system than “push” • Process mapping essential to understand the system • Accurate, focused information is needed to diagnose problems and to measure success.
Summary • Theory of Constraints – Common Sense approach to whole systems efficiency • Promotes ownership of the problem by the staff delivering the service. • Needs high level Sponsorship if it is to be effective.
