Pharmacists Are Not Mid-Level Providers.

Am J Pharm Educ 2021 Jul 22:8556. Epub 2021 Jul 22.

American Association of Colleges of Pharmacy, Arlington, Virginia

Written by members of the 2021 AACP Professional Affairs Committee, this commentary describes the perspective on why pharmacists should not be classified as "mid-level" providers.  Beyond the connotation that this classification implies that there are different levels or a hierarchy of providers, it is important to recognize that all healthcare providers bring unique and essential knowledge and contributions to the healthcare team and to patients.  Timely issues germane to pharmacists, including dependent and independent practice, provider status, and professional identity also contribute to the rationale that pharmacists, just like all other healthcare providers, should be classified by their professional identity.

Int J Lab Hematol 2021 Jul;43 Suppl 1:43-53

Department of Flow and Image Cytometry, Roswell Park Comprehensive Cancer Center, Buffalo, NY, USA.

Multiple myeloma (MM) is a heterogeneous group of mature B-cell diseases that are typically characterized by the presence and accumulation of abnormal plasma cells (PCs), which results in the excess production of monoclonal immunoglobulin and/or light chain found in the serum and/or urine. Multiparametric flow cytometry (MFC) is an indispensable tool to supplement the diagnosis, classification and monitoring of the disease due to its high patient applicability, excellent sensitivity and encouraging results from various clinical trials. In this regard, minimal or, more appropriately, measurable residual disease (MRD) negativity by MFC has been recognized as a powerful predictor of favourable long-term outcomes. Read More
