RESUMEN

BACKGROUND: The COVID-19 pandemic has placed additional stressors on physician lives. In this study, we report findings from a survey conducted among attending physician (AP) members of the American Society for Apheresis (ASFA) to elucidate the status of their well-being during the COVID-19 pandemic as well as resources provided or actions taken by their institutions and themselves personally to maintain or improve their well-being. STUDY DESIGN AND METHODS: A 17-question, voluntary, IRB-approved survey regarding well-being was distributed to the ASFA AP members between August 26, 2020 and September 16, 2020. The descriptive analyses were reported as number and frequency of respondents for each question. Non-parametric chi-square tests, ANOVA, and paired t-tests were performed to determine differences in categorical variables, changes in well-being scores, and compare time points, respectively. RESULTS: Based on the responses of 70 attending level physicians representing the United States (U.S., 53, 75.7%) and outside the U.S. (17, 24.3%), the following were observed: (1) COVID-19 negatively affects the well-being of a sub-population of APs, (2) neither institutional nor individual measures to improve well-being completely resolved the problem of decreased AP well-being during the pandemic, and (3) personal actions may be superior to institutional resources. CONCLUSION: There is a widespread decline in AP well-being during the COVID-19 pandemic that was not adequately improved by institutional or personal resources/actions taken. Institutions and physicians must work together to implement strategies including resources and actions that could further improve AP physician well-being during a public health crisis.

RESUMEN

INTRODUCTION: Obtaining vascular access (VA) is a critical part of the therapeutic apheresis (TA) treatment plan. Currently, there are no guidelines for VA decision-making and maintenance related to TA procedures. MATERIALS AND METHODS: A 28-question survey to gather qualitative information regarding VA practices was distributed to the American Society for Apheresis (ASFA) 2018 Annual Meeting attendees and all ASFA members for voluntary participation. The descriptive analyses were reported as the number and frequency of responses for each question. RESULTS: Total participation was 206 with 147 (71.4%) answering some or all 16 VA focused questions. The majority of respondents were nurses or physicians (89.0%) at sites providing ≥100 procedures. The most common TA procedures were plasma exchange, red cell exchange, and leukocytapheresis. The VA evaluation was predominantly performed by the TA service (80.3%, 118/147). The majority of TA physicians and/or providers do not insert (91.7%, 132/144) or remove (81.2%, 117/143) VA catheters. When an emergent TA procedure is needed, the majority of respondents felt <2 hours was an acceptable turnaround time for VA placement (64.3%, 92/143). The most common anticoagulant for locking catheters and/or ports was heparin. The majority of TA services (54.3%, 76/140) collect data on aborted procedures due to catheter/line/port problems unrelated to infection, but only 41.4% (58/140) collect data on infections. CONCLUSION: VA contributes significantly to the overall risks associated with and the safety of TA. Our survey shows that there is substantial variation but common themes in TA VA practices. Several areas for future research may be identified.

RESUMEN

BACKGROUND: Individuals donating whole blood 13 times in a 2-year period without development of iron deficiency anemia (superdonors) are a self-selected population that is deferred for low hematocrit (Hct) level less frequently than other donors. STUDY DESIGN AND METHODS: Iron metabolism was assessed in 138 superdonors through a questionnaire and measurement of Hct, serum ferritin, serum hepcidin, and serum growth differentiation factor 15 (GDF15). Genetic testing for HFE and JAK-2 mutations was also performed. RESULTS AND CONCLUSIONS: Iron deficiency (ferritin level, <30 microg/L) is present in more than 60 percent of superdonors. Behaviors altering iron status included casual use of iron supplements in males, but not in females, and cigarette smoking that produced increased Hct associated with decreased ferritin. The striking biochemical characteristic of superdonors is greatly decreased serum hepcidin, consistent with their need to absorb maximal amounts of dietary iron to replace that lost from blood donation. GDF15 is normal in most superdonors, indicating that GDF15 overexpression arising from the expanded erythroid pool necessary to replace donated red cells is not the biochemical mechanism for the decreased serum hepcidin. Mutations in JAK-2 were not found, indicating that undiagnosed polycythemia vera is not a common cause for successful repeated blood donation by superdonors. Mutations in HFE associated with hemochromatosis were present in superdonors at the same frequency as the normal population. However, superdonors heterozygous for the H63D mutation in HFE had significantly decreased hepcidin : ferritin ratios demonstrating for the first time that the heterozygous state for HFE mutations is associated with alterations in hepcidin expression.
