Achieving High Reliability in Histology: An Improvement Series to Reduce Errors

Lean and Six Sigma as continuous quality improvement frameworks in the clinical diagnostic laboratory

Processes to enhance customer-related services in healthcare organizations are complex and it can be difficult to achieve efficient patient-focused services. Laboratories make an integral part of the healthcare service industry where healthcare providers deal with critical patient results. Errors in these processes may cost a human life, create a negative impact on an organization's reputation, cause revenue loss, and open doors for expensive lawsuits. To overcome these complexities, healthcare organizations must implement an approach that helps healthcare service providers to reduce waste, variation, and work imbalance in the service processes. Lean and Six Sigma are used as continuous process improvement frameworks in laboratory medicine. Six Sigma uses an approach that involves problem-solving, continuous improvement and quantitative statistical process control. Six Sigma is a technique based on the DMAIC process (Define, Measure, Analyze, Improve, and Control) to improve quality performance. Application of DMAIC in a healthcare organization provides guidance on how to handle quality that is directed toward patient satisfaction in a healthcare service industry. The Lean process is a technique for process management in which waste reduction is the primary purpose; this is accomplished by implementing waste mitigation practices and methodologies for quality improvement. Overall, this article outlines the frameworks for continuous quality and process improvement in healthcare organizations, with a focus on the impacts of Lean and Six Sigma on the performance and quality service delivery system in clinical laboratories. It also examines the role of utilization management and challenges that impact the implementation of Lean and Six Sigma in clinical laboratories.

Towards high reliability in national pathology education: Evaluating the United States and Canadian Academy of Pathology educational product

The United States and Canadian Academy of Pathology (USCAP) leadership undertook a high level, global review of educational product outcomes data using high reliability organization (HRO) principles: preoccupation with failure; reluctance to simplify; sensitivity to operations; commitment to resilience; and deference to expertise. HRO principles have long been applied to fields such as aviation, nuclear power, and more recently to healthcare, yet they are rarely applied to the field that underpins these—and many other—complex systems: education. While errors in education are less calamitous than in air travel or healthcare delivery, USCAP's educational products impact over 15,000 learners a year, and thus have important implications for the future practice of pathology. Here we report USCAP's experiences using HRO principles to evaluate our keystone educational product, the “USCAP Short Course.” Following this novel method of data review, USCAP leadership was able to better understand diverse learner needs based on practice venue, training level, and course topic. Unexpected lessons included the identification of specifically challenging educational topics, such as molecular pathology, and a need to focus more resources on emerging fields such as quality and patient safety. The results allow USCAP to assess educational product performance using HRO tools, and provide strong data-driven decision support for future national pathology education strategy.

Wrong Tissue in Block

OBJECTIVES

Maintaining specimen identity during surgical pathology tissue processing is critical. Epic Beaker Laboratory Information System requires sequential scanning of specimen label and grossed blocks (block confirmation) to ensure specimen identity. We report our institution's experience with wrong tissue in block (WTIB) grossing errors before and after adopting block confirmation.

METHODS

During the first 18 months of Beaker implementation, block confirmation was not required. We then mandated block confirmation for a 3-month period. To ensure compliance, we then built a "hard stop" feature that prevents scanning any unconfirmed blocks onto a packing list. We reviewed WTIB incidents pre- and postimplementation of these solutions.

RESULTS

Before using block confirmation, we had WTIB incidents involving 17 (0.043%) of 38,848 cases. When we mandated block confirmation use, we had WTIB involving 2 (0.043%) of 4,646 cases. After implementing the hard stop feature, we had WTIB incidents involving 2 (0.005%) of 42,411 cases. Overall, there was an 88.4% (0.043% vs 0.005%; P < .001) reduction in WTIB incidents using block confirmation with a hard stop.

CONCLUSIONS

Beaker is a customizable platform that can be tailored to a laboratory's workflow. By using barcoding, implementing custom-built features, and improving workflow protocols, we significantly reduced WTIB errors.

Whole-slide Imaging: Clinical Workflows and Primary Diagnosis

Digital pathology has made great strides in recent years culminating with the approval to market devices from the Food and Drug Administration. The pathology community is now poised to begin using these systems for diagnostic purposes. This article will discuss the preparatory steps needed to implement digital pathology as well as some implementation styles that may be sufficient for a pathology department.
