Bolton Hospitals NHS Trust
Covers a population of 265,000Employs 3100 staffEmergency admissions of >38000Total beds = 779
Pathology total workload >1.4 m requests 2004/5
Blood Sciences = 50% of above

Pathology lab history
Pathology is split in 2 buildings across the hospital main corridor
Due to increasing workload, we believed that the size of the building and staffing needed to expand (business case showed spend of £650,000 was required)
The laboratory is CPA accredited

Value Stream analysis
Team of various grades from pathology, pathology users and external staff worked on value stream analysis over 4 days

Unnecessary movement
Urgents (Biochemistry)Sample 75 steps approx 40x daily =3,000Information 135 steps once a day
GP van (all labs)Samples 4924 steps per dayInformation 135 steps x2 daily

This is the minimum, it could be higher

Value statement
The delivery of a correct result for a blood sample, for the correct patient to the correct clinical team within 1 hour of receipt unless precluded by current
technology

Staff Communication
After the week, feedback sessions were held with staff.One per day for 5 daysStaff were asked for comments to be written on feedback sheet in StaffroomAnalysis of comments showed 2 categories of concern:
Staff rolesNew laboratory design
![Page 11: Applying Lean in Pathology](https://reader037.fdocuments.in/reader037/viewer/2022102815/55842c66d8b42a86478b50a1/html5/thumbnails/11.jpg)
Week two - 3P planning event
Revisited first Blood Sciences laboratory design
Reviewed staff commentsRe-calculated waste(s)
Used a lean project management tool to produce a 1-decision implementation plan
4 phasesIndividual task definition and detail
![Page 12: Applying Lean in Pathology](https://reader037.fdocuments.in/reader037/viewer/2022102815/55842c66d8b42a86478b50a1/html5/thumbnails/12.jpg)
Redesigned the Lean laboratory
![Page 13: Applying Lean in Pathology](https://reader037.fdocuments.in/reader037/viewer/2022102815/55842c66d8b42a86478b50a1/html5/thumbnails/13.jpg)

Benefits from New Design
Achieves process flow Reduced Steps
Urgent Blood Samples - reduced from 75 steps to a maximum of 57 stepsRoutine Blood Samples – reduced from 309 steps to a maximum of 57 stepsGP vans maximum of 57 steps from 2462 steps for 1 run
Strategic grouping of analysers – better utilisation , require reduced numbers of analysers
![Page 15: Applying Lean in Pathology](https://reader037.fdocuments.in/reader037/viewer/2022102815/55842c66d8b42a86478b50a1/html5/thumbnails/15.jpg)
Predicted benefits from new design
New laboratory design accepted by all staffReduced number of staff requiredReduction of floor space (40%)Reduction of travel distance (80%)Opportunities to utilise skill mix of staff in new ways
![Page 16: Applying Lean in Pathology](https://reader037.fdocuments.in/reader037/viewer/2022102815/55842c66d8b42a86478b50a1/html5/thumbnails/16.jpg)
Current progress
Understand the type of equipment required for flow processesReduction of sample processing time from an average of 5 hours to approximately 60 minutes. (Routine)Reduced the turnaround time for some tests e.g. HbA1c from 30 hours to 3 hoursThe design of the lean laboratories will have flexible benching and analysers will be on trolleys.Reduced re-work

Additional benefits for Blood Transfusion

Benefits from New Design

6S for Flow
Sort (get rid of what’s not needed)Straighten (A place for everything..)Shine (clean and wash)Safety (checking for hazards and
defects)Standardise (build into acceptable routines)Sustain (maintain the standards set by
the 6S event)

Is Lean Easy ?
![Page 28: Applying Lean in Pathology](https://reader037.fdocuments.in/reader037/viewer/2022102815/55842c66d8b42a86478b50a1/html5/thumbnails/28.jpg)
Issues
Extremely complex projectReconfiguration of services
Project delays due to external suppliers issuesScanning software for request forms not ready (external supplier)Continuing to provide a service 24/365 whilst under going major changePlenty of strangers due to configuration issuesIT issues e.g. analyser interfaces
![Page 29: Applying Lean in Pathology](https://reader037.fdocuments.in/reader037/viewer/2022102815/55842c66d8b42a86478b50a1/html5/thumbnails/29.jpg)
Issues cont’d
Changing the way staff workIntegration of previously discrete departments
HR issues (many to be addressed)
Getting ALL staff to understand leanStaff on shifts, part time staff, staff using batch techniques for many yearsSome staff are very receptiveOthers are less receptive and see it as a means of reducing staffing levels (particularly in the current NHS climate)
![Page 30: Applying Lean in Pathology](https://reader037.fdocuments.in/reader037/viewer/2022102815/55842c66d8b42a86478b50a1/html5/thumbnails/30.jpg)
General lessons
Huge changes in very short time scales have had (are having) a profound effect on all the staff.Some have adapted very quickly, some not at all yet.The magnitude of the task of managing the human issues cannot be over emphasised.It is a credit to the staff & their managers that we have progressed so far so quickly.
![Page 31: Applying Lean in Pathology](https://reader037.fdocuments.in/reader037/viewer/2022102815/55842c66d8b42a86478b50a1/html5/thumbnails/31.jpg)
General lessons
It has been (is still) a roller coaster ride of emotions & stress & tension usually all within the same day.Mutual support especially within the senior management team has played a vital role.
![Page 32: Applying Lean in Pathology](https://reader037.fdocuments.in/reader037/viewer/2022102815/55842c66d8b42a86478b50a1/html5/thumbnails/32.jpg)
Lessons learnt
Don’t leave the staff as they will revert back to their customary working practicesMust have a team leader responsible for each area who wears a “lean hat”Don’t expect the new “flow” to work to the reduced waste calculated – it will take timeDocument the new working practices –standard work

Is lean easy ?
NOChanging mindsetsChanging a 24/365 service
But this project has been achieved in 8 monthsPreviously it would have taken years!!
Pathology and this Trust are at the beginning of a journey
