Application of predonation hydration for vasovagal reactions during blood donation: a bibliometric analysis (2004–2023)

TL;DR

This paper reviews research on using hydration before blood donation to reduce vasovagal reactions, showing it's a promising and low-cost strategy.

Contribution

This is the first comprehensive bibliometric analysis of predonation hydration's role in mitigating vasovagal reactions.

Findings

Predonation hydration is a promising, low-cost strategy to enhance donor safety and retention.

Research trends over the past 3 years have focused on fear, complications, management, and hydration.

Standardization of hydration protocols is needed for effective implementation.

Abstract

Vasovagal reaction (VVR) is one of the prevalent adverse reactions encountered during voluntary blood donation, posing a risk to subsequent donations by the same individuals. Here, we present a bibliometric study aimed at mitigating VVRs.

This study retrieved pertinent publications on the correlation between predonation hydration and vasovagal reactions from the Web of Science Core Collection (WoSCC) database from 2004 to 2023. Bibliometric analysis was conducted employing bibliometrix R, VOSviewer, and CiteSpace.

This study encompassed 241 papers across 31 countries and 387 research institutions. Notably, the University of Bucharest (Romania, n = 12, 4.9%), the Australian Red Cross (Australia, n = 10, 4.1%), the University of Queensland (Australia, n = 10, 4.1%), Wayne State University (USA, n = 6, 2.5%), and Ohio State University (USA, n = 5, 2.1%) emerged as the top five contributors in publication output. The journal Transfusion was the most prolific publication venue in this field. Authors Thijsen, Amanda, and Deju, R. were identified as the most prolific contributors in this area. Over the past 3 years, research trends have predominantly focused on fear, complications, management, and hydration.

This marks the first comprehensive overview of bibliometric research aimed at understanding the preventive and mitigative effects of predonation hydration on VVR. Predonation hydration as a strategy to prevent or alleviate VVR is currently the focal point of research interest. Our findings suggest that predonation hydration is a promising, low-cost approach to enhance donor safety and retention, although standardization of protocols is needed.
