Lean Methodology for Pathology Laboratories: A Case Study from a Public Hospital

Area of Science:

• Laboratory Medicine
• Healthcare Management
• Process Improvement

Background:

• Increasing financial pressures and technological advancements necessitate enhanced quality and efficiency in laboratories.
• Evidence-based medicine applications further highlight the need for optimized laboratory workflows.
• Pathology laboratories face unique challenges in balancing cost, speed, and accuracy.

Purpose of the Study:

• To examine pathology laboratory processes and identify sources of waste.
• To determine the root causes of inefficiencies within the laboratory setting.
• To select and apply lean management techniques for waste elimination and process optimization.

Main Methods:

• A five-phase lean management implementation plan was utilized, including senior management support, observation, and employee training.
• Value stream mapping was employed, focusing on the gastric biopsy process as the product/service family.
• Waste identification involved tools such as the fishbone diagram and Pareto analysis.

Main Results:

• Currently, 73.6% of the time for a gastric biopsy sample in the pathology laboratory is considered waste.
• Key identified waste sources include cleaning issues, supply problems, lack of clinical information, equipment malfunction, and errors.
• A future target indicates a potential 4.6% improvement in efficiency through the developed lean plan.

Conclusions:

• A model for implementing lean management techniques in pathology laboratories, particularly in developing countries, has been established.
• This model aims to enhance both the efficiency and quality of laboratory services.
• The study provides a framework for optimizing laboratory operations through systematic waste reduction.
