Résumé
【Objective】 To systematically evaluate the incidence of adverse transfusion reactions in Chinese children, so as to provide scientific basis for prevention and early intervention. 【Methods】 Literature databases such as PubMed, EMbase, The Cochrane Library, CNKI, Wanfang and VIP were searched in terms of the incidence of adverse transfusion reactions in Chinese children from January 2000 to December 2022. Two researchers extracted literature data independently according to the inclusion and exclusion criteria and conducted quality evaluation of included studies according to AHRQ quality evaluation scale. Statistical analysis was performed using Stata 14.0 software. 【Results】 A total of 870 literatures were retrieved, and 13 were included in the study, with a total of 181 274 cases with blood transfusion. Meta-analysis showed that the overall incidence of adverse transfusion reactions in Chinese children was 0.79%[95%CI (0.54%, 1.04%)]. The incidence of adverse reactions of red blood cells, platelets and plasma were 0.34%[95%CI (0.15%, 0.54%)], 2.94%[95%CI (1.60%, 4.28%)] and 0.31%[95%CI (0.19%, 0.43%)], respectively. The incidence of fever reaction and anaphylaxis reaction were 0.22%[95%CI (0.13%, 0.31%)] and 0.46%[95%CI (0.30%, 0.61%)] respectively. 【Conclusion】 The overall incidence of adverse transfusion reactions in Chinese children is low, but the incidence of adverse reactions of platelet transfusion is high, which needs further prevention and control.
Résumé
【Objective】 To evaluate the clinical characteristics and risk factors of adverse transfusion reactions (ATR) in Chinese adults, and to provide evidence-based medical evidence for early prevention. 【Methods】 The controlled trial (CT) of risk factors for ATR in Chinese adults were collected through PubMed, Embase, Cochrane Library, CNKI, CMB, VIP and Wanfang database, and the retrieval time was from the establishment of those databases to January 31, 2021 Literature was selected and extracted by 2 researchers according to inclusion and exclusion criteria. Meta-analysis was performed by RevMan5.3 software. 【Results】 A total of 28 049 patients in 12 literature were included, 1 190 patients were included into the ART group and 26 859 into the non-ART group. Meta-analysis results showed that the incidence of ART was 1.63% (410/24 361), mainly allergic reaction (43.90%, 188/410) and non-hemolytic fever (40%, 164/410). Primary hematologic disease (OR=27.11, 95%CI=21.64~33.96, P 2 (OR=7.06, 95% CI=5.64~8.84, P30 min interval between blood issuing and transfusion (OR=3.40, 95% CI=2.88~4.00, P2, >30 min interval between blood issuing and transfusion, transfusion of plasma and cryoprecipitates, while transfusion of red blood cells/white blood cells/platelets was the protective factor.
Résumé
Abstract: Transfusion by blood and blood products forms an important part of treatment. But this is not free from transfusion reactions which may be in the form of fever, rashes, shivering, anaphylaxis or even death. Hemovigilance is a programme of reporting such events.Materials and Methods: The present study was conducted in a tertiary care hospital of Jammu, (J& K). Permission was taken from Institutional Ethics Committee, Govt. Medical College, Jammu. A pretested questionnaire was prepared and circulated among practitioners. They were given time of 15 minutes to fill that questionnaire. After 15 minutes, the filled questionnaire were collected and were analysed. The data was presented in tabulated form.Results: Total 50 practitioners were included in the study. All the practitioners had knowledge about transfusion reactions. Only 10% of the practitioners had knowledge that transfusion reactions can be prevented, 40% of the practitioners had knowledge about hemovigilance programme and had an idea that transfusion reactions can be reported. But only 10% of the practitioners knew where to report and who can report, 6% knew how to report. Only 48% of the practitioners thought that transfusion reactions should be reported, 70% of the practitioners thought that transfusion reactions can be dangerous. 40% of practitioners told that seminars/CMEs should be planned. 80% of practitioners had encountered transfusion reactions, but only 2% had documented the same. 10% of the practitioners had attended seminars, CMEs. Many reasons were quoted for not reporting transfusion reactions.Conclusion: Overall, most of the practitioners have a positive attitude towards transfusion reaction reporting but knowledge regarding the haemovigilance concept is poor and the majority of them never reported such reaction. Hence, our study demands increased awareness and continued training to strengthen the haemovigilance system.
Résumé
Background: Haemovigilance Programme of India was launched in 2012 with the purpose to identify, analyse and learn the complications related to transfusion and blood donation, in order to avoid such complications in future. Though it is essential to identify the Adverse Transfusion Reactions (ATR) to reduce the incidence and make transfusion easier; there are rare reports available about knowledge, attitude, and practice (KAP) of Healthcare Professionals (HCP) for haemovigilance.Methods: In this cross-sectional study, pre-validated questionnaire designed for assessing the KAP, the possible ways to improve transfusion reaction reporting and causes of underreporting were distributed among 220 Healthcare Professional (HCP) in Nashik, Maharashtra.Results: The response rate of the study was 93%. Amongst them 58% HCP had poor knowledge while only 9% had good knowledge about haemovigilance. According to respondents, training to the HCP, CME’s, making reporting compulsory and launching of a toll-free helpline number will mark a milestone in improving transfusion reaction reporting. Legal liability issue and lack of time & knowledge were the main factors which discouraged them from reporting.Conclusions: Overall, most of HCP in Nashik have a positive attitude towards transfusion reaction reporting but knowledge regarding the haemovigilance concept is poor and the majority of them never reported ATR. Hence, our study demands increased awareness and continued training to strengthen the haemovigilance system, especially ATR reporting.
Résumé
BACKGROUND: Adverse transfusion reactions (ATRs) are clinically relevant to patients with significant morbidity and mortality. This study aimed to review the cases of ATR reported in the recipient-triggered trace back system for a recent nine-year period in Korea. METHODS: Nine-year data obtained from 2006 to 2014 by the trace back system at the Division of Human Blood Safety Surveillance of the Korean Centers for Disease Control (KCDC) were reviewed. The suspected cases were assessed according to six categories: (i) related to, (ii) probably related to, (iii) probably not related to, (iv) not related to transfusion, (v) unable to investigate, and (vi) under investigation. RESULTS: Since 2006, 199 suspected serious ATRs were reported in hospitals and medical institutions in Korea, and these ATRs were reassessed by the division of Human Blood Safety Surveillance of the KCDC. Among the reported 193 cases as transfusion related infections, hepatitis C virus (HCV) infection (135, 67.8%) was reported most frequently, followed by hepatitis B virus (HBV) infection (27, 13.6%), HIV infection (13, 6.5%), syphilis (9, 4.5%), malarial infection (4, 2.0%), other bacterial infections (3, 1.5%), HTLV infection (1, 0.5%), and scrub typhus infection (1, 0.5%), respectively. Of the 199 cases, 13 (6.5%) cases were confirmed as transfusion-related (3 HCV infections, 3 malarial infections, 1 HBV infection, 2 Staphylococcus aureus sepsis, 3 transfusion-related acute lung injuries, and 1 hemolytic transfusion reaction). CONCLUSIONS: This is the first nationwide data regarding serious ATRs in Korea and could contribute to the implementation of an effective hemovigilance system.
