Lean in healthcare is a methodology that aims to improve patient care and minimize costs. It draws its principles from the Toyota Production System, which was created to increase efficiency and decrease waste. This approach is used to identify and remove non-value-adding activities in healthcare processes, commonly known as the seven wastes. We will explore the concept in more detail below.
What is Lean in Healthcare?
Lean in healthcare is a methodology applied by healthcare organizations to enhance patient outcomes and minimize costs. It is based on the Toyota Production System (TPS), a set of principles designed to lower costs and increase efficiency. The TPS originated in the automobile industry in the mid-1950s as a method of improving quality and decreasing costs. It has since been adapted and implemented in several industries, including healthcare.
The application of lean in healthcare aims to identify and remove non-value-adding activities from healthcare processes, known as the seven wastes. These wastes include overproduction, waiting, transportation, over-processing, motion, defects, and inventory. As a result, lean principles can decrease waste and improve efficiency, enabling healthcare organizations to provide improved patient care at a lower cost.
Benefits of Lean in Healthcare
Lean in healthcare has a number of benefits, including:
- Increased patient satisfaction with improved quality of care
- Improved patient safety through reduced medical errors
- Reduced costs through the elimination of wasteful activities
- Increased efficiency through streamlined processes
- Improved staff morale through increased job satisfaction
Lean Principles
The principles of lean in healthcare are based on the Toyota Production System (TPS). The core principles of lean include:
- Respect for people
- Continuous improvement
- Kaizen (“change for the better”)
- Focus on the customer
- Elimination of waste
These principles are designed to create a culture of continuous improvement, where everyone is empowered to identify and eliminate waste from healthcare processes.
Seven Wastes in Healthcare
The seven wastes in healthcare are non-value-adding activities that reduce efficiency and increase costs. These wastes include:
- Transportation
- Inventory
- Motion
- Waiting
- Overproduction
- Over-Processing
- Defects
Let’s take a closer look at each of these wastes and how they can be reduced in healthcare.
Transportation
Transportation waste in healthcare refers to the inefficiencies and increased costs that result from unnecessary movements of patients, equipment, or supplies. Some examples include :
- The transfer of medication between the pharmacy and its intended destination.
- Moving supplies from storage to different floors.
- Patients have to travel between buildings for various aspects of their care, which is often mandatory but can be made more efficient.
Lean principles can help hospitals in reducing transportation waste by optimizing the movement of people, equipment, and supplies. This can be achieved through the implementation of strategies such as creating effective work cells, standardizing transportation processes, and minimizing the distance traveled for a task. Reducing transportation waste can lead to cost savings, improved delivery times, and increased productivity, ultimately benefiting the hospital and its patients.
Inventory
Inventory waste in healthcare refers to the inefficiencies and increased costs that result from overstocking, understocking, or mismanagement of medical supplies and equipment. This can lead to increased expenses, waste, and reduced quality of care for patients.. Some examples include :
- Medications that may have reached their expiration date
- Consumables that have exceeded the required stock level
- Redundant bedside equipment that is no longer necessary.
Lean principles can help hospitals in reducing inventory by optimizing their supply chain management. Lean principles involve eliminating waste, reducing unnecessary steps, and streamlining processes to increase efficiency. This approach can be applied to hospital inventory management in several ways, such as consolidating suppliers, reducing overstocking, and implementing just-in-time inventory systems. By implementing lean principles, hospitals can reduce inventory carrying costs, free up valuable storage space, and increase the availability of critical supplies.
Motion
“Motion waste” is a term used in the healthcare industry to describe activities that add no value to patient care and are non-essential from the perspective of healthcare providers. These activities involve unnecessary movement of people, equipment or supplies. This waste contributes to increased costs, and reduced efficiency, and can even negatively impact patient outcomes.
Examples of motion waste in healthcare are common and include tasks such as searching for supplies, walking to different areas to perform tasks or collect information, moving patients too frequently due to scheduling or lack of communication, and even the inefficient layout of the healthcare facility itself. These movements are not directly related to providing medical care and can increase the risk of errors, limit the amount of time doctors, nurses and other clinicians spend with patients as well as lengthen wait times for patients.
To eliminate motion waste in healthcare, hospitals can apply lean principles, a set of methodologies that originated in the manufacturing industry and prioritized the identification and elimination of waste. Lean principles encourage continuous improvement and emphasize the elimination of unnecessary activities to improve efficiency, lower costs, and enhance the overall quality of care.
Waiting
Waiting waste in healthcare refers to the unnecessary time delay that patients experience before receiving medical care. It includes waiting for appointments, test results, treatment, and other services. Examples of waiting waste in healthcare include long wait times at the physician’s office or emergency room, delayed surgeries, and prolonged hospital stays.
Lean principles can help hospitals in eliminating waiting waste by streamlining processes, reducing unnecessary steps, and improving the flow of information and resources. This can be achieved through a continuous improvement approach that involves identifying and eliminating waste using techniques such as value stream mapping, flow analysis, and mistake-proofing. By reducing waiting waste, hospitals can improve patient satisfaction, increase operational efficiency, and reduce costs.
Overproduction
Overproduction waste in healthcare refers to producing or providing services beyond the actual demand or need of patients, leading to unnecessary expenditures, stocking of inventory, and utilization of resources.
Examples of overproduction waste in healthcare include an excess inventory of medical supplies, equipment, and medication, ordering unnecessary laboratory tests, scheduling appointments that are not needed, and admitting patients who do not require hospitalization.
Lean principles can help hospitals in eliminating overproduction waste by establishing a patient-centric approach that focuses on the customer’s needs and preferences rather than generating profits. Adopting a lean methodology, such as the Just-in-Time (JIT) inventory system, can prevent overstocking of medical supplies and equipment. Streamlined processes, such as standardized scheduling, can reduce the number of unnecessary appointments, tests, and procedures while maintaining the quality of care provided.
Overprocessing
Overprocessing waste in healthcare refers to the unnecessary time, effort, or resources spent on tasks that do not add value for patients or improve outcomes. Examples of over-processing waste in healthcare include excessive paperwork, redundant testing, unnecessary treatments, inefficient workflows, and duplicative documentation efforts.
To eliminate over-processing waste, healthcare providers can apply lean principles. Lean principles emphasize standardization, value stream mapping, and continuous improvement. Standard operating procedures for tasks can help eliminate unnecessary variation and streamline workflows. Value stream mapping can help identify areas of over-processing waste, enabling targeted efforts to reduce waste and improve efficiency. Continuous improvement efforts based on staff inputs can help eliminate over-processing waste over time.
By using lean principles, hospitals can reduce costs, improve patient outcomes, and increase staff satisfaction by focusing on tasks that add value and eliminating tasks that do not.
Defects
Defects waste in healthcare refers to any mistakes or errors that occur during clinical processes, which result in a deviation from standard quality care. Examples of defects waste in healthcare include medication errors, misdiagnosis, patient falls, delayed diagnosis or treatment, and hospital-acquired infections.
Lean principles can help hospitals in eliminating defects waste by promoting a culture of continuous improvement and focusing on identifying and removing waste from clinical processes. Some strategies for reducing defects waste using lean principles include implementing standardized work processes, using visual management systems to track progress and identify areas for improvement, and involving frontline staff in continuous improvement initiatives. By eliminating defects waste through lean principles, hospitals can improve patient safety and care quality while also reducing costs and inefficiencies.
