ABSTRACTApheresis is performed worldwide for an increasing number of indications. The development of common data elements (CDE) for apheresis related areas may facilitate conduct of new research, enhance quality initiatives including benchmarking, and improve patient care. This report describes the systematic development of the Uniform Apheresis Case Report Form (UACRF) as part of the Apheresis in the United States (ApheresUS) program. A consensus panel of 17 diverse experts in apheresis, related specialties, and electronic case report form (eCRF), and database development was assembled. The panel met via online conferencing from November 17, 2020 to December 1, 2021. A draft document was posted online for public comment from October 11, 2021 to November 10, 2021. Feedback was collected using an online survey tool. The consensus panel revised the UACRF. This version was converted to an eCRF with additional changes made to improve usability in this format. The final version of the UACRF was created on August 24, 2023. The UACRF contains 16 modules: procedure and subject eligibility, patient demographics, general procedure information, laboratory parameters, vascular access, common procedure elements, eight procedure specific modules (mononuclear cell collection and seven therapeutic modalities), outcomes, and site information. A total of 137 data elements were created, including 57 with one or more subelements. The UACRF is the first systematic attempt to develop CDE for therapeutic apheresis and white blood cell collections. Further validation of the UACRF is necessary to confirm the tool's ability to collect the relevant data elements and determine the usability of the form.

AbstractSince vaccination for SARS‐CoV‐2 coronavirus started, the trajectory of patient numbers infected with the virus has improved once; however, variants of SARS‐CoV‐2 have emerged and more people have been infected; therefore, pandemic status is still far from resolution. Government and social efforts to prevent coronavirus infection continue in most states in the US and globally even after the Centers for Disease Control and Prevention declared some restriction relief for fully vaccinated people in March 2021. Healthcare institutions and various professional organizations have developed guidelines or policies to prevent the spread of these coronaviruses in the setting of apheresis. In this report, the issues that apheresis services may encounter under the current COVID‐19 (SARS‐CoV‐2 coronavirus disease) pandemic will be discussed with potential strategies that can be adapted for efficient and optimum use of apheresis resources.

AbstractSince 1986, the American Society for Apheresis (ASFA) has published practice guidelines on the use of therapeutic apheresis in the Journal of Clinical Apheresis (JCA) Special Issue. Since 2007, updated guidelines have been published every 3 years to reflect current evidence based apheresis practice with the most recent edition (8th) published in 2019. With each edition, the guidelines are reviewed and updated based on any newly published literature since the last review. The PEXIVAS study, an international, randomized controlled trial comparing therapeutic plasma exchange (TPE) vs no TPE and standard vs reduced dose steroid regimen on the primary composite outcome of end stage renal disease or death in patients with ANCA‐associated vasculitis (AAV), was published in February 2020. This study represents the largest study on the role of therapeutic apheresis in AAV published to date and prompted the JCA Special Issue Writing Committee to reassess the current AAV fact sheet for updates based on this newly available evidence. This interim fact sheet summarizes current ASFA recommendations for the evidence‐based use of therapeutic apheresis in AAV and supersedes the recommendations published in the 2019 guidelines.
