J Multidiscip Healthc 2024; 17:473-489. [PMID: 38318487 PMCID: PMC10840532 DOI: 10.2147/jmdh.s443674] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2023] [Accepted: 01/09/2024] [Indexed: 02/07/2024] Open
Abstract
Purpose The current state of the art in process modeling of blood banking and transfusion services is not well grounded; methodological reviews are lacking to bridge the gap between such blood banking and transfusion processes (and their models) and their automation. This research aims to fill this gap with a methodological review. Methods A systematic mapping study was adopted, driven by five key research questions. Identified research studies were accepted based on fulfilling the following inclusion criteria: 1) research studies should focus on blood banking and transfusion process modeling since the late 1970s; and 2) research studies should focus on process automation in relation to workflow-based systems, with papers classified into categories in line with the analysis undertaken to answer each of the research questions. Results The search identified 22 papers related to modeling and automation of blood banking and transfusion, published in the period 1979-2022. The findings revealed that only four process modeling languages were reported to visualize process workflows. The preparation of blood components, serologic testing, blood distribution, apheresis, preparation for emergencies, maintaining blood banking and transfusion safety, and documentation have not been reported to have been modeled in the literature. This review revealed the lack of use of Business Process Modeling Notation (BPMN) as the industry standard process modeling language in the domain. The review also indicated a deficiency in modeling specialized processes in blood banking and transfusion, with the majority of reported processes being described as high level, but lacking elaboration. Automation was reported to improve transfusion safety, and to reduce cost, time cycle, and human errors. Conclusion The work highlights the non-existence of a developed process architectural framework for blood banking and transfusion processes, which is needed to lay the groundwork for identifying and modeling strategic, managerial, and operational processes to bridge the gap with their enactment in healthcare systems. This paves the way for the development of a data-harvesting platform for blood banking and transfusion services.

Multicenter evaluation of a high-throughput microarray platform for extensive red blood cell phenotyping and antibody screening. Transfusion 2023; 63:1563-1570. [PMID: 37177851 DOI: 10.1111/trf.17395] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Revised: 04/18/2023] [Accepted: 04/21/2023] [Indexed: 05/15/2023]
Abstract
BACKGROUND Blood typing and antibody screening are key elements of transfusion safety. However, available single platform, flexible, and affordable technologies are limited, especially for extended phenotyping. Microarray-based technology allows for this extended phenotyping with the flexibility of piecemeal analysis. STUDY DESIGN AND METHODS This study was conducted in three blood donor laboratories to determine the performance of a high-throughput microarray-based system for ABO, RH1-RH5, and KEL1 typing, ABS and extended phenotyping (RH8, KEL2&3, FY1&2, JK1, MNS3). Specimens were tested simultaneously on local platforms and on the microarray-based system. When discrepancies were identified, resolver testing were performed. RESULTS In total, 4862 blood samples were tested for standard phenotype, 4257 for antibody screening and 2194 for extended phenotype. Results were available for 92.12% of the samples. The overall percent agreements were: 100% for ABO, 99.8% for RH1, 99.24% for RH2-5 and 99.86% for KEL1, 93.16% for antibody screening, and 99.68% for extended phenotype. CONCLUSIONS This microarray-based system provides highly comparable results to current CE marked assays. The ability to continuously test 3000 microarrays in 1 day, providing simultaneously both extended RBC phenotyping and antibody detection drives laboratory efficiencies. The results of our study validate the performance of this new technology; however, the percentage of samples without results must be reduced and further analysis is required to interpret the ABS screening performances. This could constitute a real breakthrough in transfusion, making it possible in the long term, on a single platform, to carry out all the analyses necessary for the qualification of donations.

Abstract
BACKGROUND AND OBJECTIVES Implementation of automated steps in preparing blood components for transfusion from whole blood collections has produced improvements in multiple fields. The aim of this review is to summarize data from existing literature related to automation of whole blood processing systems. MATERIALS AND METHODS We searched MEDLINE for studies comparing semi-automated and fully automated whole blood processing systems published before 20 July 2021. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. Additionally, we performed a manual search. RESULTS We identified 500 studies, of which 459 (92%) did not meet the eligibility criteria, and finally 17 studies were included in the analysis. Manual search included six additional studies. Publication year ranged from 2004 to 2021. Automation reduced the run-time (from 92 to 76 min), improved recovery of haemoglobin in red cell concentrates (RCCs) and resulted in higher red blood cell and platelet yields. Automation also reduced discard rates due to whole blood bag ruptures (1.2%-0.1%), low volume of RCCs (<200 ml; 0.5%-0.03%) and haemolytic plasma (2.1%-0.6%). Automation could reduce the number of full-time equivalent (FTE) operators or maintain the number of FTE operators while performing additional procedures, and it reduced to 1.13 m2 the space required for the device. CONCLUSION Automation of whole blood processing resulted in continued improvements in productivity, product quality and technical features. However, too few publications are available to reach strong conclusions. Therefore, it is necessary to expand the scientific knowledge in this field.

Comparison between tube test and automated column agglutination technology on VISION Max for anti-A/B isoagglutinin titres: A multidimensional analysis. Vox Sang 2021; 117:399-407. [PMID: 34318939 DOI: 10.1111/vox.13184] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2021] [Revised: 07/08/2021] [Accepted: 07/12/2021] [Indexed: 12/01/2022]
Abstract
BACKGROUND AND OBJECTIVES VISION Max (Ortho Clinical Diagnostics, Raritan, NJ) measures anti-A/B isoagglutinin titres using automated column agglutination technology (CAT). We compared tube test (TT) and CAT of VISION Max comprehensively, including failure mode and effect analysis (FMEA), turnaround time (TAT) and cost, and suggested modified CAT (MCAT). MATERIALS AND METHODS For 100 samples (each 25 for blood type A, B and O with anti-A and anti-B), anti-A/B isoagglutinin titres were measured by TT and CAT (1:2-1:1024 dilution), as well as by MCAT (with agglutination at 1:32 dilution, then perform additional testing from 1:64 to 1:1024). We assessed the agreement and correlation between TT and CAT and compared FMEA (risk priority number [RPN] score), TAT (h:min:sec) and cost (US dollar, US $) among TT, CAT and MCAT. RESULTS TT and CAT showed overall substantial agreement (k = 0.73) and high correlation (ρ ≥ 0.75) except blood type O with anti-A (ρ = 0.68). Compared with TT, CAT showed lower RPN scores in FMEA and similar TAT and cost (FMEA, 33,700 vs. 184,300; TAT, 15:23:00 vs. 14:26:40; cost, 1377.4 vs. 1312.4, respectively). Regarding FMEA, TAT and cost, MCAT was superior to CAT or TT (43,810; 13:28:00; 899.2, respectively). CONCLUSION This is the first multidimensional analysis on VISION Max CAT for measuring anti-A/B isoagglutinin titres. The results of anti-A/B isoagglutinin titres by CAT were comparable with those of TT. MCAT would be a safe, time-saving and cost-effective alternative to TT and CAT in high-volume blood bank laboratories.

Clinical performance evaluation of Elecsys HIV Duo, Anti-HCV II, HBsAg II, Anti-HBc II, and Syphilis assays for routine screening of first-time blood donor samples at a French blood donation center. Transfus Clin Biol 2021; 29:79-83. [PMID: 34214660 DOI: 10.1016/j.tracli.2021.06.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2021] [Revised: 05/26/2021] [Accepted: 06/22/2021] [Indexed: 11/24/2022]
Abstract
OBJECTIVES Implementing fully automated analyzers has become a crucial safety step in blood donation centers. The Elecsys® assays were evaluated on the cobas e 801 module (Roche Diagnostics) for routine first-time blood donor screening. MATERIALS & METHODS Five Elecsys infectious disease assays were tested on the cobas e 801 module at Etablissement Français du Sang, Montpellier, France (March-April 2018). The performance of Elecsys HIV Duo, Anti-HCV II, HBsAg II, Anti-HBc II, and Syphilis assays was compared with PRISM HIV O Plus, HCV, HBsAg, HBcore, and newbio pk TPHA assays (specificity analyses)/ARCHITECT Syphilis TP (sensitivity analyses), respectively. Specificity was determined in residual fresh serum samples from unselected first-time blood donors (n≥5195 per parameter). Elecsys assay sensitivity was tested using 30 preselected, positively characterized samples per assay and compared with archived routine testing data for comparator assays. RESULTS Across all parameters, specificities for repeatedly reactive samples ranged from 99.81-100.00% for Elecsys assays and 99.71-99.98% for comparator assays. Sensitivities of Elecsys and comparator assays were the same for hepatitis C (85.19%), hepatitis B surface antigen (70.00%), hepatitis B core antigen antibodies (100.00%), and syphilis (100.00%). The sensitivity of the Elecsys HIV Duo assay was higher than the comparator assay (83.33% vs. 76.67%), but the difference was not statistically significant. CONCLUSIONS Elecsys infectious disease assays on the cobas e 801 module demonstrated high specificity and sensitivity for screening first-time blood donor samples, and were comparable with other commercially available assays. The Elecsys assays are reliable tests for screening blood donations.

Performance and reliability of a benchtop automated instrument for transfusion testing: a comparative multicenter clinical study in the US population. Transfusion 2019; 59:3511-3518. [PMID: 31532543 DOI: 10.1111/trf.15520] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2019] [Revised: 08/08/2019] [Accepted: 08/22/2019] [Indexed: 11/29/2022]
Abstract
BACKGROUND Heavy workload in hospital transfusion services and blood centers necessitates the implementation of automated platforms. We evaluated the performance of Erytra Eflexis (Diagnostic Grifols), a recently developed midsize automated instrument for pretransfusion testing, in comparison with a US Food and Drug Administration (FDA)-cleared device (Erytra). Reproducibility and repeatability of the results were also investigated. STUDY DESIGN AND METHODS Studies were conducted using the same card technology and reagents at three US sites. Tests were performed on 9174 specimens from hospital patients (55.61%) and blood donors (43.39%). Evaluations included 18,413 ABO/D/reverse typing; 9084 Rh phenotypes, 4640 K phenotypes, 2052 antibody screenings, 1232 antibody identifications, 469 direct antiglobulin tests, 612 IgG crossmatches, and 700 ABO-compatibility crossmatches. A reference blood panel was also sent to each center, for a total of 3900 replicate tests. Concordance between results with the two instruments and performance among the different centers were statistically evaluated. RESULTS Agreement between instruments was 99.84% for 37,202 test results, with 61 discrepancies (0.16%). Percentages of positive and negative agreement were 99.82% and 99.85%, respectively. No discrepancies were observed in 12,276 tests for direct ABO/D grouping. Discrepancies were observed during antibody identification (n = 19), antibody screening (n = 15), and reverse grouping (n = 10). Investigations of the discrepancies were resolved in favor of the study instrument in 55.73% of the cases. Erytra Eflexis obtained the expected results in the reproducibility analysis. CONCLUSION This multicenter study demonstrates that Erytra Eflexis with its gel card technology and reagents is reliable and substantially equivalent to the FDA-cleared instrument used as the reference.
