Apheresis practice variation during the COVID-19 pandemic: Results of a survey

BACKGROUND

The COVID-19 pandemic affected healthcare delivery across all specialties including apheresis. To describe the changes in apheresis service practices that occurred during the pandemic, the American Society for Apheresis (ASFA) Apheresis Medicine Attending Physician Subcommittee conducted a survey study.

STUDY DESIGN AND METHODS

A 32-question survey was designed and distributed to 400 ASFA physician members on September 7, 2022. Attending physicians responded to questions about whether and how apheresis service practices changed during the COVID-19 pandemic compared with the time period prior to the pandemic in terms of: (1) procedure types and volumes, (2) patient consultation workflow, and (3) the use of telemedicine. Descriptive analyses were reported as number and frequency of responses.

RESULTS

The survey response rate was 13.8% (55/400). Of these respondents, 96.4% (53/55) were attending physicians. The majority of respondents (42/53, 79.2%) indicated that the types of procedures performed during COVID-19 compared to pre-pandemic did not change. Most frequently for apheresis procedure volume, respondents reported: no change in their monthly inpatient volume (21/47, 44.7%) and a decrease in their monthly outpatient volume (28/46, 60.9%). Prior to COVID-19, 75.0% (30/40) of respondents performed consultations at bedside for inpatients and 67.4% (29/43) performed consultations at bedside for outpatients. Bedside consultations decreased in both settings during the pandemic but were still most frequently performed by attending physicians. At the same time, the use of telemedicine increased for 15.4% of survey respondents during COVID-19.

CONCLUSION

Some, but not all, respondents observed or made changes to their apheresis service during the COVID-19 pandemic. A subset of changes, such as increased utilization of telemedicine, may persist.

Apheresis medicine education during the early phase of the COVID-19 pandemic

BACKGROUND

The COVID-19 pandemic introduced challenges and disruption across healthcare, including apheresis medicine (AM). In this study, we report findings from a survey conducted among American Society for Apheresis Physician Committee (ASFA-PC) members to describe the impact of the COVID-19 pandemic on AM education practices.

STUDY DESIGN AND METHODS

A voluntary, anonymous, 24-question, institutional review board-approved survey regarding AM teaching during the pandemic was distributed to ASFA-PC members in the United States between December 1, 2020, and December 15, 2020. Descriptive analyses were reported as number and frequency of respondents for each question. Free text responses were summarized.

RESULTS

Responses were received from 14/31 (45%) of ASFA-PC members, of whom 12 practiced at academic institutions. Among these, 11/12 (92%) transitioned to virtual platform for AM trainee conferences during the pandemic. A variety of resources were employed to support independent AM learning. While 7/12 (58%) respondents did not change the informed consent process for AM procedures, others delegated this process or introduced remote alternatives. The most common method respondents used to conduct AM patient rounding was a hybrid in-person/virtual model.

CONCLUSION

This survey describes the adaptations and changes AM practitioners made to trainee education in response to the early phase of the COVID-19 pandemic. The transition to virtual and/or hybrid trainee learning and AM rounds underscores the importance of digital AM resources. Further study of the effects of the pandemic and its impact on AM trainee education, as well as patient care is warranted.

Therapeutic Plasma Exchange in Certain Immune-Mediated Neurological Disorders: Focus on a Novel Nanomembrane-Based Technology

Therapeutic plasma exchange (TPE) is an efficient extracorporeal blood purification technique to remove circulating autoantibodies and other pathogenic substances. Its mechanism of action in immune-mediated neurological disorders includes immediate intravascular reduction of autoantibody concentration, pulsed induction of antibody redistribution, and subsequent immunomodulatory changes. Conventional TPE with 1 to 1.5 total plasma volume (TPV) exchange is a well-established treatment in Guillain-Barre Syndrome, Chronic Inflammatory Demyelinating Polyradiculoneuropathy, Neuromyelitis Optica Spectrum Disorder, Myasthenia Gravis and Multiple Sclerosis. There is insufficient evidence for the efficacy of so-called low volume plasma exchange (LVPE) (<1 TPV exchange) implemented either by the conventional or by a novel nanomembrane-based TPE in these neurological conditions, including their impact on conductivity and neuroregenerative recovery. In this narrative review, we focus on the role of nanomembrane-based technology as an alternative LVPE treatment option in these neurological conditions. Nanomembrane-based technology is a promising type of TPE, which seems to share the basic advantages of the conventional one, but probably with fewer adverse effects. It could play a valuable role in patient management by ameliorating neurological symptoms, improving disability, and reducing oxidative stress in a cost-effective way. Further research is needed to identify which patients benefit most from this novel TPE technology.

Tele-ECP: A feasible telemedicine-based approach to extracorporeal photopheresis

The acquisition of telecommunication technologies in clinical practices is transforming medical care capabilities, whereas applying telemedicine in apheresis medicine has resulted in the revolutionary concept of "telapheresis." This manuscript aims to describe the regulatory landscape of telapheresis by presenting the first "tele-ECP" (telemedicine-based approach to extracorporeal photopheresis) reported in the United Arab Emirates. The tele-ECP procedure was done successfully in a patient with chronic graft-versus-host disease, who, despite having one vascular access-related adverse event, it was solved promptly without further complications. Therefore, this telemedicine-based approach arose as a feasible practice, but required direct physical contact with other trained and privileged/credentialed staff.
