‘Some personal views on Creating Pathology Networks’
Drawing on 3.5 years at synlab, Latchmore’s 4 UK and 2 overseas pathology
network projects, observations from UK and international labs
Hugh Risebrow, CEO Latchmore Associates
November 7th 2018
- Is there anything wrong with the Status Quo?
- Systems thinking vs Silo Thinking
- The hub fallacy
- No ‘one size fits all’ approach
- 10 other observations on pathology network reconfiguration
2. Is there anything wrong with the Status Quo – largely single Trust pathology services?
Duplication of management/ specialist resources. Lack economy of scale….
Cost area % total Issue with single trust pathology service
Lab MES or equiv 23.7%
Lab other non pay 6.5%
Lab processing staff pay 45.3% Sub-scale for specialist tests. (Volume tests ?)
Lab management 9.1% Every lab reinventing wheel for SOPs, quality management, training etc
Send away tests 2.8% Poor prices. Multiple suppliers with high logistics/ admin costs. (Pre
NPeX) transcription costs/ risks
Consultants 4.4% Often single-handed sub-specialists. Lack of resilience. Issues with
recruitment/ retention in DGHs
logistics 0.9%
IT full costed 1.8% Network systems lower per Trust and enable results sharing
HR/ finance Overheads 1.8%
Estates at market rate 3.6% Specialist units often require large footprint
Not always in path budget
Lack of buying power. Large groups save up to 40%. High procurement
process costs
3. Systems thinking vs Silo Thinking
Pathology is a small but critical element of c70% of patient pathways ..
Systems Thinking Approach:
- Start with patient -> Optimise/ personalise pathway
- Pathology service meets pathway needs
- Pathology service flexes to changing need
- Pathway Outcomes ✅
- Pathway cost ✅
- Pathology cost may be higher ❔
Silo Thinking Approach:
- Save 5% of 3.5%
- Optimise pathology silo
- Fixed Target Operating Model
- Pathway Outcomes ❔
- Pathway cost ❔
- Pathology cost ✅
4. Systems thinking vs Silo Thinking – a (quite common?) example …
GP Local Lab
Before
- Samples collected by 1300 taken to local lab
- Results back by 4pm
- GP manages patients with unexpected results
GP Spoke Lab Hub Lab
After
- Samples collected by 1300 taken to spoke lab
- Samples spun and entered onto LIMS
- Samples sent in bulk to hub late pm
- Samples processed in hub
- Unexpected results sent to out of hours service
- OOH much less familiar with patients and more
likely to visit patients or send to A&E
Appears common in networks. Variations include a) not centrifuging or booking at spoke, and b) processing urgent
samples at spoke IF correctly labelled.
5. The hub fallacy – let’s consider the demand in an example 4 hospital network ..

Direct labour + MES cost/ test vs tubes/ day
We considered the labour + MES costs of a blood science lab providing the top
40 tests by volume
• Multi-disciplinary scientist
scenario
• (Sub-specialist scientists scenario
more extreme at right)
• Curve flattens c 8-10,000 tube/
day
• Curve rises slightly based on
empirical data c 15,000
7. The distributed network resulted in lower direct staff and MES costs (c11%*) and offered other benefits:
Avoided building new hub lab
Avoided relocating staff (or more likely redundancy/ re recruitment)
Provided greater resilience
* Difference greater with sub-specialist scientist
(nb each network has different circumstances and needs to develop its own solution)

Network blood science tests pa
in network send away
* Some tests moved categories for pragmatic or clinical reasons
40 tests in all labs
96.3% b/s volume
Smallest lab c30/
day of ‘test 40’
75 tests in hub
3.4% b/s volume
‘test 75’ c10/day in
hub (economic to
run dailyO
144 tests only economic at supra network level
Gain volume or send away, or swap specialist
tests with other networks
Probably the most challenging aspect to gain
agreement on in UK or international labs

Three generic lab configuration options, with broadly similar operating costs ..
- Many sub-options
- Optimum solution unique to each network –
no ‘one size fits all’
- Starting circumstances
- Distances/ travel times
- Need to re-use lab space
- Clinical specialties
- NHSI feel misunderstood. Open to all types of
network options, not wedded to ‘hub+spoke’
10. 10 other observations regarding lab reconfigurations
1. (Deming principle 8) Reduce fear of change – eg guarantee no compulsory redundancies
2. Appoint network management team at an early stage, to avoid ‘jockeying for future position’
3. Initially create IT interconnectivity/ single LIMS, and standardise equipment – Key enablers to
standardising SOPs, training, quality manuals/ systems and creating workforce mobility
4. MES by sub-specialty vs single lab MES ?
5. Large commercial labs have different views on tracks. Separate out track investment and
validate ROI
6. Centralising histo processing doesn’t require centralising consultants. Consultants can remain
with cut-up lab. Empirical data - forcing consultants to move will lead to resignations.
7. Significant capital not needed – buildings, equipment and LIMS can be procured on a ‘revenue’
basis
8. Evolution not revolution. UK and International networks which evolved steadily are more
successful than those which rushed to implement
9. Many specialist tests economical at ‘Supra network’ scale – consider swapping specialist tests or
developing niches Eg Sandwell (TMPT toxicology)
10.All other good project management principles apply. These are complex change programmes.
