Introduction to Lean Healthcare

Introduction

As an NHS professional, you know the challenges of keeping operations running smoothly. However, can you imagine a world where every step is streamlined, freeing up your team to focus on delivering exceptional patient care? That’s the promise of Lean Healthcare – a transformative approach revolutionising how you work. In ‘Introduction to Lean Healthcare’ you will discover;

• The fundamentals of the Lean principles
• The importance of developing a culture of continuous improvement, and
• Get an overview of some of the most used tools and techniques in Lean healthcare

Lean Fundamentals

At its core, Lean Healthcare is about three types of activity and ultimately eliminating waste i.e. those non-value-adding activities that consume your resources without contributing to the care or positive experience of your patients. Think about the time your patients spend waiting for appointments, test results, or discharge home? Consider the unnecessary motion and transportation involved in moving supplies or equipment between your departments? Or the defects and rework that can occur due to errors or miscommunications?

These are just a few examples of the eight types of waste that Lean aims to identify and eliminate. By adopting a Lean mindset, you’ll learn to see your processes through a new lens, one that focuses on maximising value for your patients and staff while minimising waste and inefficiency for your organisation.

Lean and Organisational Culture

Lean Healthcare isn’t just about streamlining your processes – it’s about helping you create a culture of continuous improvement that empowers everyone, from your frontline staff to your senior leaders, to identify opportunities for process optimisation and driving meaningful change.

Imagine a world where all your staff, clinical and non-clinical, are actively engaged in improving the way they work, where their insights and ideas are valued? Where they feel empowered to challenge the status quo and suggest innovative solutions. That’s the power of Lean Healthcare – it fosters an environment of respect, collaboration, and continuous learning, where you are all invested in delivering the highest quality of care for your patients.

To truly reap the benefits, you’ll need to embrace a culture of continuous improvement, one that fosters respect for people, empowers frontline staff, and encourages experimentation and learning from failures. It’s a journey, that requires commitment, perseverance, and a willingness to challenge the status quo. The rewards are immense – improved patient outcomes, enhanced operational efficiency, and a workforce that is engaged, empowered, and relentlessly focused on delivering the highest quality of care.

Examples of Lean Implementation

Now, I know what you might be thinking – “But our processes are complex, and our resources are already stretched thin. How can we possibly find the time or energy to implement Lean?” That’s a valid concern, but here’s the thing – Lean Healthcare isn’t about adding more work to your current workload; it’s about working smarter, not harder. By eliminating waste and optimising your processes, you’ll free up valuable time and resources that you can reinvest into delivering better patient and staff care and experience.

Emergency Department

Let me give you a real-life example. At a busy NHS hospital, the emergency department was struggling with long wait times and overcrowding. By applying Lean principles and mapping out the patient flow, they identified bottlenecks and non-value-adding activities that were contributing to the delays. Through a series of rapid improvement workshops, they streamlined the triage process, implemented visual management systems to track bed availability, and optimised the discharge process to free up beds more quickly.

The results? Wait times were reduced by over 30%, patient satisfaction scores improved, and staff reported feeling more engaged and empowered to drive continuous improvement.

Lean Healthcare isn’t just about improving patient flow – it can be applied to virtually any process or function within your organisation. From optimising surgical setups and reducing changeover times to streamlining discharge processes and enhancing patient safety through mistake-proofing techniques, the possibilities are endless.

Operating Room

At a large NHS trust, a Lean initiative focused on improving the operating room turnaround process. By implementing SMED (Single Minute Exchange of Die) principles and standardising the theatre setup procedures, they were able to reduce changeover times by over 40%, increasing operating room utilisation and reducing costly delays.

Examples of Lean Tools and Techniques

8 Wastes of Lean Healthcare:

Read here about what waste is in Lean. Perhaps one of the most important concepts in Lean the 8 Wastes categorise those areas that are impeding your aim of reaching perfection. It’s incredibly important that you and your staff understand each one of these categories of waste. Once armed with the knowledge of what they are, you’re better positioned to go out looking for them and implementing solutions to eliminate them.

The 8 Wastes:

• Transportation
• Inventory
• Motion
• Waiting
• Overproduction
• Over-Processing
• Defects or rework
• Staff underutilisation

6S:

6S is a Lean methodology that can help you stay focused on creating and maintaining an organised, clean, and efficient workplace. The 6Ss help you to reduce waste, improve efficiency, and create a visual workplace. You’ll be amazed at the amount of time that is wasted looking for ‘stuff’ e.g. theatre equipment, patients’ notes, a simple pen! All this time adds up and dilutes your abilities to be efficient and effective.

The 6S’s are:

• Sort (remove unnecessary items)
• Set in Order (organize remaining items)
• Shine (clean)
• Standardise (create standards for the first 3S’s)
• Sustain (make it a habit), and
• Safety (focus on safety)

Process Mapping:

Process mapping is a powerful Lean tool and it involves you creating a map, i.e. a visual representation of the steps in your processes. This allows you to analyse the process flows, identify waste/inefficiencies e.g. delays etc. Process maps come in different ‘forms’ e.g. value stream maps, swimlane diagrams, to name a few. Process mapping is key for you to understand your processes before improving them. Read this blog about ‘The NHS Professional’s Guide to Effective Process Mapping in 7 Steps‘.

Due to its simplicity, convenience and adaptability process mapping is probably one of the most utilised tools in the NHS. You definitely don’t need a degree in engineering to become proficient with it. Actually all you need is sticky notes, marker pens, a roll of brown paper and ideally a wall to put everything on.

Visual Management:

Visual management is a Lean tool that we all use without realising it. Have you ever;

• Stopped at a traffic light?
• Checked your petrol gauge?
• Used an egg timer?
• Checked the temperature gauge?
• Used a RAG status on a report?

All the above are examples of visual management. The reason why they are all around is for one simple fact – they’re understood by most people. Whether you’re in London, Berlin, Beijing or Moscow we all stop at a red light. This is why visual management is at the heart of Lean.

Visual management uses visual cues like signs, labels, markers, displays, etc. to help you communicate important information quickly and clearly. This reinforces standards, highlights abnormalities. Examples include shadowboards kanban signals, andon lights, performance metric boards, etc. It creates a visual workplace for you to quickly and easily communicate any given situation ‘at a glance’ i.e. within 60 seconds.

Standard Operating Procedures (SOPs):

SOPs are visual instructions that help you capture best practices, for performing a process or operation, and sharing them with other colleagues. They ‘standardise’ work to reduce variation, facilitate training, and ensure consistent execution and quality. Well-designed SOPs are an essential part of documenting and sustaining your Lean improvements.

The power of SOPs is;

• They limit confusion
• Offer robust support for training of new employees
• Standardises complex procedure
• Improves quality
• reduces rework / defects

Set Up Reduction

Set up reduction (also known as single minute exchange of die (SMED)), is a Lean methodology focused on reducing changeover times on manufacturing equipment and processes. The principles are equally relevant and effective in an operating room / theatres environment.

Set up reduction incorporates many of the 6S principles as well as other Lean techniques to reduce the time it takes to go from one product to another. You might be thinking that it’s not applicable to healthcare as set up reduction is for ‘products’ and the NHS deals with ‘patients’. Actually the principles translate extremely well into healthcare – particularly for operating theatres.

I’ve worked on theatre utilisation improvement programmes and seen theatre staff benefit from assessing their change-over processes i.e. getting the theatre ready from one patient to the next. In each case 6S has been a core element in minimising the time for ‘external’ work. Essentially what I am saying is not to get hung up on the product vs patient argument. Keep an open mind, look at the principles involved, have a go and make up your own mind!

The key steps involve:

1. Separating changeover steps into external (performed while equipment is running) and internal (performed when equipment is stopped)
2. Converting as many internal steps as possible into external steps
3. Streamlining and simplifying all remaining internal and external steps

The goal is to dramatically reduce downtime between patient procedures by optimising changeover processes. This increases theatre utilisation and offers flexibility when planning theatre lists.

Rapid improvement workshops

Rapid improvement workshops (also called kaizen events or kaizen blitzes) are short, intensive events (typically 3-5 days) where a cross-functional team comes together to rapidly improve a focused process or problem area.

The workshops follow a structured approach:

• Preparation phase to set goals, select team, gather data
• Multi-day event to analyse current state, identify improvements, implement changes
• Follow-up to sustain improvements through monitoring and accountability.
• Rapid workshops allow organisations to achieve breakthrough improvements quickly by dedicating focused time and resources. They drive employee engagement and generate momentum for continuous improvement.

Both SMED and rapid improvement workshops are Lean tools that you can leverage to streamline your processes, reduce waste, and drive operational excellence. By utilising tools like 6S, process mapping, visual management, SOPs and addressing the 8 wastes, you can streamline patient flow, reduce errors, improve quality and create more value for your patients.

Summary

Lean healthcare is the application of principles and practices, borne out of manufacturing to identify and eliminate waste in healthcare processes. The ultimate goal being to deliver higher quality, safer and more efficient patient care.

At its core, Lean focuses on maximising value for the patient. Lean tools and techniques like process mapping, 6S etc. analyse processes and make problems visible. From this countermeasures can be implemented to eliminate waste.

For example, mapping a process can identify bottlenecks and non-value added steps in activities like admissions or discharges. 6S creates organised, visual workspaces and is applicable to a shop floor and office environment. Mistake-proofing uses visual cues and ‘forcing functions’ to prevent errors. Rapid improvement workshops bring staff together to achieve focused process improvements over a focussed and short period of time.

Importantly, Lean is not just a toolkit. To get the maximum benefits from Lean requires developing an organisational culture of continuous improvement. A culture where everyone is empowered to identify problems, challenge the status quo, and implement solutions.

Picture your team actively seeking opportunities to optimise workflows, reducing delays and cutting out unnecessary process steps. In your ‘future state’ everyone of your resources is invested in delivering maximum value to patients.

The rewards from Lean healthcare are immense – improving outcomes for your patients, enhancing efficiency of your processes and having your workforce relentlessly pursuing and continuously eliminating waste.
