What is Lean Healthcare & Its Models?

In hospitals, every second matters — nurses rush between rooms, physicians consult on critical cases, and patients anxiously await their turn. Lean healthcare offers a way to bring order to the chaos and transform how care is delivered.

Imagine a patient arriving at the Emergency Room with severe abdominal pain. In a traditional healthcare setting, they might face long wait times, unnecessary paperwork, and clashes between departments. But with lean healthcare, the patient is quickly triaged and directed to a dedicated care team following standardized procedures to minimize delays.

Overview of Lean Healthcare

The concept of “lean” originated in manufacturing, with the term coined by John Krafcik in 1988. James Womack and colleagues later defined lean more broadly in 1996 as a “systematic approach to identifying and eliminating waste (non-value-added activities) through continuous improvement by flowing the product at the pull of the customer in pursuit of perfection.”

The Triple Aim of US Healthcare was created by the Institute of Health Improvement (IHI). It provides a helpful framework, pushing healthcare systems to simultaneously improve patients’ experience, population health, and per capita costs.

While lean has proven models, each organization must modify these models to suit their own context. Establishing a mindset of constant improvement at all levels is necessary for success. When done correctly, lean healthcare methods can greatly transform care delivery.

Waste Categories Used in Lean Healthcare

In lean healthcare, waste is anything that does not help make the patient’s care and experience better. Lean principles aim to find and remove wasteful elements, making operations easier and improving efficiency in healthcare.

The concept of waste in lean healthcare is often categorized into eight types:

Defects

Errors can happen in medical procedures due to wrong diagnoses or faulty medical equipment that need fixing. These problems can raise costs, harm patients, and slow down medical care. For example, if a patient is diagnosed incorrectly, it can result in the wrong treatment. This may lead to serious health complications and higher medical costs.

Overproduction

If we make more medical equipment and medicine than we need, it creates waste. This waste can include unnecessary diagnostic tests or treatments that are not needed for patient care. For example, doing too many blood tests for a patient when they are not needed wastes resources and incurs more healthcare expenses.

Waiting

If patient care is delayed because of more waiting time for consultation, test results, medical equipment, or doctor availability, this issue can cause long stays of patients in hospital territory and neglect care about patient satisfaction. For example, a patient in the Emergency Room (ER) waiting for many hours to see a doctor may feel discomfort.

Non/Underutilized Talent

Not using the skills and knowledge of medical staff well can cause many problems for healthcare practices. Because of mistakes and low spirits, healthcare workers cannot achieve their best. For example, a nurse trained specifically in wound care might be tasked with recording daily patient visits and discharges, rather than focusing on the specific needs of patients.

Transportation

Transportation is considered the unnecessary movement of patients, staff , or other medical material within healthcare practice. Moving patients between departments without a good reason can be a waste. For example, moving a patient many times for tests can increase the chance of errors and cause more discomfort.

Inventory

Having too few or too many healthcare supplies and medications can hurt patient care. Having too many medical supplies or medications can result in more items getting expired. On the other hand, not having enough can lead to long waits for patient care. For example, having too much medical stock that expires before all items are used can cause money loss. Also, delays in treatment due to inventory shortage can have serious effects or even lead to death.

Motion

Staff may lose time and work less efficiently because of extra physical movement. This can cause poor patient care and wastage of time. For example, a nurse hired for checking patients’ Blood Pressure (BP) spends too much time locating the BP apparatus instead of helping the patient with their worries. In that case, this can disturb the overall productivity of staff.

Extra or Over-Processing

Doing extra work that is not needed, like unnecessary tests, can raise medical costs and slow down patient care without helping anyone. For example, duplicating the same patient information in different treatment forms can lead to more mistakes and extra work for staff.

The annual cost of waste in the US healthcare system is estimated at almost $750 billion, which includes unnecessary services, excessive administration costs, and inefficient delivery.

Six Principles of Lean Healthcare

Focusing more on better teamwork and working together is very important when using lean healthcare principles. Healthcare practices should improve their use of lean principles. They need to look for ways on finding areas to improve and use data to help them. Using lean healthcare ideas can help your clinic create a stable and balanced environment that offers high-quality, waste-free care.

1). Value

It is important to understand what is valuable for treating patients from their point of view. This principle is about finding and providing healthcare services that can help improve patient care and make patients happier. Focusing on what patients need in healthcare can remove unhelpful activities and improve the overall experience for patients.

2). Value Stream Mapping

Value stream mapping shows all steps in a process to find and remove waste. We can look at the whole process from when patients arrive to when they leave. This helps healthcare providers make everything work better and ensure patients move through the system easily.

3). Flow

This principle helps all healthcare processes work well without any problems. It can also highlight the ongoing flow of patients, their information, and medical supplies or medications. By removing all delays and problems, healthcare practices can make wait times shorter and improve healthcare services.

4). Pull

A pull system is a way of providing healthcare services based on what patients need, instead of having set appointments or pre-planned schedules. This principle helps prevent making too much and makes sure all resources are used properly and effectively, which leads to better care for patients and better management of resources.

5). Perfection

Always try to improve all healthcare processes. This principle emphasizes the importance of ongoing evaluation and improvement. It encourages all healthcare providers to always look for ways to enhance quality, reduce errors, and increase efficiency.

6). Respect for Everyone

It is important to recognize and value the contributions of all healthcare staff to keep quality care. This principle aims to create a helpful work environment where all staff can share their ideas to improve processes. When healthcare organizations keep a good culture, they can improve patient care and make staff happier.

Lean Methodologies and Implementation in Healthcare

Lean methodologies and how to use them are important for better patient care, making operations work better, and cutting down on waste. Here are different methodologies that are used to make the healthcare system better.

1). Value Stream Mapping (VSM)

Value stream mapping is a useful tool that healthcare organizations can use to make patient care better. It shows a clear picture of the whole process of giving care to patients, from beginning to end. This covers all tasks, like ordering supplies and administering medicine. The map helps teams find problems, waste, and things that do not work well so they can fix them. This simple process lowers costs and waiting times and makes care better.

2). Kaizen (Continuous Improvement)

Kaizen is a process of constantly looking for ways to improve. It involves everyone in an organization working together to make small, incremental changes on a daily basis. The goal is to eliminate waste and streamline processes.

In healthcare, Kaizen can help make the movement of patients in a clinic better. A team plans every part of the patient journey, starting from checking in, to seeing the doctor, and ending with checking out. They find problems or slow parts in each stage and think of ideas to make the process easier. This could be as easy as moving furniture around or adding signage. Kaizen means making small changes all the time, not big changes all at once.

3). Just In Time (JIT)

The Just In Time (JIT) method means getting supplies and materials only when you need them, rather than stocking up in advance. The goal is to avoid overproduction and excess inventory, which can cause waste. With JIT, you make or order just what is required, just when it is required. This helps save money and improve efficiency.

4). Root Cause Analysis (RCA)

Root Cause Analysis is a way to solve problems in healthcare. It helps find the main reasons for issues. It means looking into problems to discover the real reasons why they happened. The purpose of RCA is to discover ways to stop problems from happening again.

5). Kanban (Card You Can See)

Kanban is a way to see and manage work as it goes through different steps. It uses cards or signals to show tasks or work items that go through different steps from beginning to end. The goal is to visualize workflow, limit work-in-progress, and maximize efficiency. Think of a Kanban board with sticky notes moving across columns to understand when something is ready to be worked on, in progress, or completed.

6). Poka-Yoke (Error Proofing)

Poka-Yoke is a lean methodology that helps stop mistakes before they happen. It focuses on building quality into processes by adding simple fail-safes that make errors nearly impossible. The goal is to design systems where the next logical step is the correct step. This eliminates the need for expensive defect detection and inspection processes down the line.

7). Heijunka (Production Leveling)

Heijunka is a lean methodology that aims to smooth out the flow of work over time. It involves leveling the mix and quantity of production across a time period. The goal is to eliminate unevenness, overburden and waste. Heijunka creates a steady predictable pace so operations can work at an optimal volume. This helps reduce variability and stress on the system.

Examples of Lean Healthcare

The following are some easy examples of how lean healthcare can help improve healthcare practices and make managing tasks easier:

Example #1 ➜ Reducing Wait Times in the Emergency Room

Have you ever had to wait for hours in the emergency room before being seen? Lean healthcare can help reduce those long wait times. Hospitals use a method called Value Stream Mapping to map out the entire journey a patient takes from walking in the door to being discharged. By streamlining the processes in the emergency department, hospitals can cut down on wasted time by up to 30%, leading to happier patients.

Example #2 ➜ Faster Patient Discharges

Getting discharged from the hospital can often be a long, frustrating process with lots of paperwork and communication issues. Lean healthcare uses a method called Kaizen, which means “continuous improvement.” A team of healthcare workers reviews the discharge process, identifies inefficiencies, and makes changes like pre-discharge planning and electronic documentation. This can reduce the overall discharge time by 20-40%, freeing up beds for new patients more quickly.

Example #3 ➜ Faster Lab Test Results

Have you ever had to wait a long time for lab test results before your doctor could diagnose you or give you medication? Lean healthcare helps labs use a “Just-In-Time” approach, where they schedule tests based on demand rather than doing big batches. This way, they can speed up their processes and get results back 20-30% faster.

Example #4 ➜ Reducing Hospital-Acquired Infections

Nobody wants to go to the hospital and catch an infection! Lean healthcare uses Root Cause Analysis to identify the sources of hospital-acquired infections. Hospitals can then implement strategies like better equipment sterilization and improved hand hygiene to cut down on these harmful infections.

Pros and Cons of Lean Healthcare

Lean healthcare has many advantages if you can implement it in your healthcare practice. However, it also has some disadvantages that can be tackled by implementing correct strategies.

Pros of Lean Healthcare

✅ The main benefit of lean healthcare is that it removes waste and improves all medical processes. This makes operations more efficient. You can do this by cutting out extra steps, organizing patient movement, and making work processes simpler.

✅ Various lean methods help find and remove activities that do not add value, which can lower operational costs effectively. You can lower these costs by cutting down on inventory costs, waiting times, and using resources more efficiently.
