February 2023—The CAP and three other organizations told the FDA in a Jan. 6 letter they are increasingly concerned that it is not recognizing updated antimicrobial susceptibility interpretive criteria, or breakpoints, in a sufficiently timely manner.
January 2023—Laura Esserman, MD, MBA, can still recall her Eureka moment. She had just seen a talk on residual cancer burden by pathologist W. Fraser Symmans, MB.ChB, a pioneer in the field. “When I saw Fraser present this,” says Dr. Esserman, director, University of California San Francisco Breast Care Center, “I knew immediately that MRI would work and that residual cancer burden would complement it. MRI was basically a snapshot of RCB over time. I realized that we had to institute RCB—we had to standardize our approach.” Until then, she and her colleagues across the I-SPY trial sites relied on individual pathologist assessment for each case. The pathologic complete response rate, or pCR, hovered at about 34 percent. That insight was soon followed by another. Intrigued by what she heard, Dr. Esserman and her pathologist colleagues from all the I-SPY sites traveled to MD Anderson, where Dr. Symmans helped develop the residual cancer burden system, for training.
January 2023—Guidelines for the diagnosis of von Willebrand disease, published in 2021, have raised questions about which von Willebrand factor activity assay laboratories should use.
January 2023—For the central microbiology laboratory serving Barnes-Jewish and four other hospitals in the St. Louis area, validating and implementing a new blood culture system and moving to a shorter incubation time came at a perfect time: right before the pandemic.
January 2023—Respiratory viruses were up in most states when Compass Group members met online Dec. 6 with CAP TODAY publisher Bob McGonnagle, and some were looking to centralize their now decentralized rapid molecular testing. At least one system had already done so. In California, a new law requires fentanyl screening be included in drug screens in all general acute-care hospital lab settings.
January 2023—Due out this spring is the CAP’s Color Atlas of Flow Cytometry. It consists of 71 cases and provides examples of the full range of hematolymphoid diseases that can be productively analyzed by flow cytometric immunophenotyping. Its editors are David Dorfman, MD, PhD, of Harvard Medical School and Brigham and Women’s Hospital; William Karlon, MD, PhD, of the University of California San Francisco Medical Center; and Michael Linden, MD, PhD, of M Health Fairview-University of Minnesota Medical Center. CAP TODAY recently asked Dr. Dorfman a few questions about the atlas. His answers to our questions and a sample case follow.
January 2023—The definition of “adequate” per the Merriam-Webster dictionary is “sufficient for a specific need.” In cytopathology, it is defined by the quantity and quality of the cellular material sampled. The final interpretation of a cytopathology report is almost universally preceded by an adequacy statement. While the essence of “adequacy” stays the same, its application varies depending on the specimen type and the site sampled. Furthermore, in the current era of personalized medicine, the definition of adequacy has expanded from “enough cells to make a morphologic diagnosis” to “enough cells to make a diagnosis and perform ancillary studies.”
January 2023—In recent years, a standardized classification system for the cytology of serous body cavities has been proposed. The system, known as the International System for Reporting Serous Fluid Cytopathology (ISRSFC), published by Ashish Chandra, et al.,1 in 2020, aims to enhance the reproducibility of cytologic diagnoses, thereby facilitating clearer communication with clinicians. The diagnostic categories are as follows: I. Non-Diagnostic; II. Negative for Malignancy; III. Atypia of Undetermined Significance; IV. Suspicious for Malignancy; V. Malignant. Each progressive diagnostic category from I through V carries with it an increasing risk of malignancy. This brief review article aims to highlight the salient points of each diagnostic category and includes discussion of recent publications and our own institutional experience.
January 2023—Automation and point-of-care, reflex, and viscoelastic testing were some of what came up when a group spoke with CAP TODAY publisher Bob McGonnagle in late November about hemostasis testing. Also tossed in: Results reporting to the EHR, which “can always be improved,” said Eric Salazar, MD, PhD, of University of Texas Health San Antonio. And D-dimer, one of the pandemic’s “health care heroes,” said Nichole Howard of Diagnostica Stago. Here’s what they said about all that and more.
January 2023—When I was newly elected into my officer role at the CAP in 2019, I had the opportunity to join a meeting of a committee under the umbrella of the Council on Accreditation. This was a committee whose work I knew little about but which I quickly grew to appreciate. In this committee I saw an extreme focus on operational processes and quality management structures. They wanted to prevent errors, not just fix them. This focus on process was different from the focus on blame that we often see in medicine. As I listened to Gaurav Sharma, MD, lead the CAP 15189 Committee, I knew I was among folks dedicated to pushing for ever-better care and quality for our patients and our laboratories.
