Hemovigilance

BACKGROUND AND OBJECTIVES: Transfusion safety may be becoming dependent on the financial resources made available for transfusion structures and may vary between high-income countries (HIC) and low-to-middle-income countries (LMIC). To assess whether there is a difference in the reported TR between these two groups of countries, we examined TR reported in Tunis the capital of Tunisia, a LMIC, and compared their frequency with reported TR in HIC. MATERIALS AND METHODS: Data of TR were collected from transfusion incident report (TIR) forms declared by healthcare facilities in Tunis between 2015 and 2019...

BACKGROUND: Transfusion-related errors are largely preventable but may lead to blood product wastage and adverse reactions, resulting in patient harm. In the United States, the incidence of transfusion-related errors is poorly understood nationally. We used data from the National Healthcare Safety Network (NHSN) Hemovigilance Module to describe and quantify transfusion-related errors, as well as associated transfusion-related adverse reactions and blood product wastage. METHODS: During 2014-2022, data from the NHSN Hemovigilance Module were used to analyze errors, including near misses (errors with no transfusion), incidents (errors with transfusion), and associated serious adverse reactions (severe, life-threatening, or death)...

The field of haemovigilance continues to develop, building on more than forty years of international experience. This review considers the current scope and activities of haemovigilance around the world and explores aspects of preparation for the advent of new blood products and alternative therapies to transfusion; new tools for data acquisition (including patient- and donor-reported outcomes, and data from 'wearables') and the analysis and communication of haemovigilance results.

BACKGROUND: Correct classification of transfusion reactions is important not only for effective patient care and donor management but also for accurate tracking of events in hemovigilance systems. We compared the ability of a generative artificial intelligence (AI) system to correctly diagnose hypothetical clinical situations as transfusion reactions in comparison to previous studies reporting the accuracy of transfusion medicine (TM) specialists in assessing these cases. METHODS: An AI system was requested to assess 36 case scenarios to provide a diagnosis, severity, and imputability of the transfusion reactions using the CDC National Healthcare Safety Network (NHSN) criteria...

Despite their use in life-saving treatment, blood and blood products can cause life-threatening complications. To administer blood transfusion safely, national guidelines and protocols should be consulted in healthcare organizations. In Türkiye, there are guides and regulations published by the Ministry of Health. With the definition of hemovigilance in the regulations; training in clinical use of blood and transfusion practice fields is now mandatory. This study presents data from a survey designed to assess transfusion knowledge levels of clinical departments for the purpose of planning our training programs...

BACKGROUND: Due to chemotherapy-induced neutropenia or hematologic malignancies, immunocompromised cancer patients may have higher incidence of febrile nonhemolytic transfusion reactions compared with the general population and frequently require platelet transfusions. This quality improvement project compared the safety of transfusion using prestorage leukocyte-reduced and pooled whole blood-derived platelets (Acrodose/WBD) with conventionally produced poststorage WBD platelets (RDP) using an active hemovigilance system...

BACKGROUND: Use of the National Healthcare Safety Network (NHSN) has been essential to the success of the Massachusetts Hemovigilance Program and has allowed for the timely identification of signals and trends over a defined population that correlate with national and international hemovigilance (HV) data. Here, we outline how the NHSN system is used for monitoring HV data in Massachusetts and encourage adoption of NHSN for nationwide HV surveillance. STUDY DESIGN AND METHODS: A collaboration that grew over time between local HV stakeholders and the Massachusetts Department of Public Health (MDPH) resulted in the change from a paper-based method of reporting adverse reactions and monthly transfusion activity for compliance with state requirements to replacement with statewide adoption of reporting via NHSN...

INTRODUCTION: In 2018, platelet (PLT) additive solution-E (PAS-E) was introduced. The implementation of PAS-E was expected to diminish the number of allergic reactions in recipients following a PLT transfusion. Here, we evaluated the efficacy and safety of transfusions with PLTs stored in PAS-E. STUDY DESIGN AND METHODS: After implementation of PAS-E, data were collected from 2 cohorts of patients with hematological disorders as well as oncology patients, receiving PLTs in PAS-E...

BACKGROUND AND PURPOSE: Hemovigilance is a set of monitoring methods that covers the blood transfusion chain, from collecting blood and blood products to monitoring the blood recipients. To this end, any error in this process can have serious and irreparable consequences for patients. The present study aimed to investigate the quality of hemovigilance process in Iran, using the first two steps of Six Sigma model. METHODS: This was a quantitative cross-sectional study that was conducted over 6 months (from August 20, 2021, to February 20, 2022) at Afzalipour Hospital in Iran, using the first two steps of Six Sigma model...

BACKGROUND: Hemovigilance (HV) is usually based on voluntary reports (passive HV). Our aim is to ascertain credible incidence, severity, and mortality of transfusion-associated adverse events (TAAEs) using an active HV program. STUDY DESIGN AND METHODS: Prospective cohort study to estimate transfusion risk after 46,488 transfusions in 5830 patients, using an active HV program with follow-up within the first 24 h after transfusion. We compared these results to those with the previously established passive HV program during the same 30 months of the study...

INTRODUCTION: Dengue is the most fatal virus disease spread by mosquito bites and Aedes aegypti is the main transmitting agent. It is an endemic disease in the tropical and subtropical regions, currently affecting more than 100 countries. Although most patients present mild forms of the disease, a considerable proportion of individuals has severe alterations in the blood count. The aim of this study was to evaluate the consumption pattern of blood components in epidemic and non-epidemic periods and to verify if there was an impact on dengue cases and the death rate...

BACKGROUND AND OBJECTIVES: ABO antigens are among the most immunogenic, but the haemolytic risks of ABO incompatibilities involving a donor with a weak ABO phenotype are little documented. MATERIALS AND METHODS: This retrospective case series assessed the incidence of acute haemolytic transfusion reaction (AHTR) among ABO-incompatible recipients of A3 blood in Québec (Canada). Transfusion safety officers reported laboratory AHTR indicators measured ≤24 h pre- and post-transfusion...

INTRODUCTION: Reporting of transfusion reactions is good practice and required by many guidelines. Errors in the transfusion chain can also lead to severe patient reactions and depend on active error reporting. We aimed to characterize transfusion incidents and asked whether workup of transfusion reactions may also contribute to revealing logistical errors. METHODS: Transfusion medical records from 2011 to 2019 at our tertiary medical centre, as well as forensic autopsy reports, digitized sections, and court records from 1990 to 2019 were analysed...

BACKGROUND: Prehospital transfusion is a way of improving the management of hemorrhagic shock. In France, prehospital transfusion is struggling to develop, both because of logistical difficulties and particularly restrictive legislation. To comply with this, we propose to store the blood products (BPs) in ground ambulances with refrigerated boxes allowing remote continuous monitoring of storage conditions, called "NelumBox" (Tec4med Lifescience GmbH). To open them, the ambulance's team needs a code that is only given by the Transfusion Center if the request meets all required regulatory criteria...

Blood transfusion saves millions of lives each year. It is a well-established treatment, and many procedures are applied to avoid transmitted infections. However, throughout the history of transfusion medicine, many infectious diseases arose or were recognised, bringing up an impact on the blood supply, as the difficulties in diagnosing new diseases, the decrease in blood donors, the challenges for the medical team, the risks for the receptor and the related costs. This study aims to review historically the principal infectious diseases transmitted through the blood that circulated worldwide in the 20th and 21st centuries, considering the impact on the blood banks...

PURPOSE: In Norway, blood donors using antihypertensive medication were deferred until 2015. Following revision of the national directive, these donors could be allowed, providing stable dose for at least 3 months, adequate blood pressure control and no adverse effects caused by the therapy. The new practice was evaluated by a quality study where the major aim was to establish whether donations from blood donors on antihypertensive medication pose a risk to the donor. The risk was assessed by counting the number and categorizing the adverse events related to blood donation...

INTRODUCTION: Following the first assessment of the effects of safety measures taken against transfusion-transmitted bacterial infections (TTBI), the Paul-Ehrlich-Institut (PEI) decided to newly analyze risk minimization measures (RMM) using German hemovigilance data from 2011 to 2020, focusing on blood components, recipients, and bacterial strains. MATERIALS AND METHODS: The PEI assessed the imputability of all reported serious adverse reactions (SAR) relying mainly on microbiological test results...

BACKGROUND: Assuring the quality and safety of blood and blood components is an essential element of health care in all countries and requires government commitment and legal frameworks. Ineffective regulation of blood and blood components has far-reaching consequences that are not limited to the affected countries but also have extensive global implications. SUMMARY: In this review, we summarize the work of the project BloodTrain funded by the German Ministry of Health within the framework of the Global Health Protection Programme to strengthen regulatory structures in Africa that are imperative to guarantee the improved availability, safety, and quality of blood and blood products...

BACKGROUND: Pulmonary complications of blood transfusion, including transfusion-related acute lung injury (TRALI), transfusion-associated circulatory overload (TACO), and transfusion-associated dyspnea, are generally underdiagnosed and under-reported. The international TRALI and TACO definitions have recently been updated. Currently, no standardized pulmonary transfusion reaction reporting form exists and most of the hemovigilance forms have not yet incorporated the updated definitions...

BACKGROUND: France converted to universal pathogen reduced (PR; amotosalen/UVA) platelets in 2017 and extended platelet component (PC) shelf-life from 5- to 7-days in 2018 and 2019. Annual national hemovigilance (HV) reports characterized longitudinal PC utilization and safety over 11 years, including several years prior to PR adoption as the national standard of care. METHODS: Data were extracted from published annual HV reports. Apheresis and pooled buffy coat [BC] PC use was compared...
