RESUMEN

BACKGROUND AND OBJECTIVES: To develop key performance indicators (KPI) for use in quality assessment of our institutional goal-directed massive transfusion (GDMT). MATERIALS AND METHODS: A team comprising our transfusion and emergency medicine departments carried out a cross-sectional data analysis of GDMT in adult patients from January 2021 to December 2022. The study was rooted in the Define, Measure, Analyse, Improve, Control (DMAIC) approach. Features of KPIs were (a) importance, (b) scientific soundness and (c) feasibility. Study parameters were defined and analysed using measures of central tendencies and benchmark comparison. RESULTS: Ninety-two massive transfusion events occurred and 1405 blood components were used. Trauma was the leading cause, followed by postpartum haemorrhage and upper gastrointestinal bleeding. Appropriate GDMT activation was observed only in 43.47% of events. The turnaround time (TAT) was within the benchmark in 85.8% of events with an average of 16 ± 10 min. The average utilization of blood components was 20.5 (interquartile range [IQR] = 11.3) in the appropriate group and 5.5 (IQR = 4.25) in the inappropriate group with a wastage rate of 3.5%. Duration of activation was 6.19 ± 4.59 h, and the adherence to thromboelastography was 66.3%. Overall mortality was 45.65%, and the average duration of hospital stay was 6.1 ± 5.9 days. CONCLUSION: The KPIs developed were easy to capture, and the analysis provided a comprehensive approach to the quality improvement of the GDMT protocol.

RESUMEN

BACKGROUND AND OBJECTIVE: We compared the overall clinical outcome in formula-based protocol (1:1:1) and thromboelastogram (TEG)-guided goal-based massive transfusion (MT) in the resuscitation of patients with hemorrhagic shock. MATERIALS AND METHODS: This was a retro-prospective case-control study conducted over a period of 2 years among the patients who received MT using a 1:1:1 fixed ratio protocol (controls, Group A) and goal-based protocol (cases, Group B) guided through TEG. Patients were matched for the type and severity of the clinical conditions. Utilization of blood components, clinical outcomes, transfusion-related complications, and total mortality rates were compared between the groups. RESULTS: There were 113 patients in the formula-based group and 109 patients in the goal-based transfusion group who were matched for injury severity scores. The total blood components utilized were 1867 and 1560, respectively, with a 17.7% reduction associated with the use of TEG. Patients were divided into normal, hypo, and hypercoagulable based on TEG, and a higher transfusion rate was associated with hypocoagulable TEG (942 vs. 610). The prothrombin time, activated partial thromboplastin time, R time, and K time had a significant positive correlation with the need to transfuse more than 20 blood components, whereas platelet count, base excess, alpha angle, MA, and CI had a negative correlation (r = 0.268, P < 0.001). At the end of goal-directed transfusion, 75% of the patients were free of transfusion support (vs. 65.4%) and only 6.9% of the patients had coagulopathy (vs. 31.8%) compared to formula-based resuscitation with a 10% reduction in mortality. CONCLUSION: TEG-guided goal-based approach helped to reduce blood component utilization with a reduced incidence of coagulopathy at the end of the MT while improving patient survival.

RESUMEN

INTRODUCTION: Anti-D detection and titration plays a major role in RhD negative antenatal cases both, for monitoring maternal as well as fetal status as well as initiation of early therapeutic interventions, such as intra-uterine transfusions (IUT) to improve maternal as well as fetal morbidity and mortality and reduce the adverse effects of haemolytic disease of fetus and newborn (HDFN). We conducted a survey focusing on the policies and procedures of anti-D detection and titration among major tertiary care centres across India. METHODOLOGY: The survey was drafted by a working group of transfusion medicine and immunohematology specialists from six different centres in India. Data were obtained via the use of an online questionnaire. RESULTS: Results were categorised into four categories, Hospital information, immuno-haematological testing methodology, clinical significance of anti-D testing and the role of transfusion medicine specialists. The survey highlighted the modalities as well as the methodologies of anti-D detection and titration in antenatal women across different major tertiary care centres in India. CONCLUSION: This survey provided a unique snapshot of the prevalent methodologies being employed by major tertiary care centres across the country for detection and titration of anti-D levels as well as the important role it plays in the therapy of affected antenatal women to minimise adverse effects on the fetus.

RESUMEN

Autoimmune hemolytic anemia (AIHA) is a common term for several disorders that differ from one another in terms of etiology, pathogenesis, clinical features, and treatment. Management of patients with AIHA has become increasingly evidence-based in recent years. While this development has resulted in therapeutic improvements, it also carries increased requirements for optimal diagnosis using more advanced laboratory tests. Unfortunately, limited data are available from developing countries regarding the testing and transfusion management of patients with AIHA. The main objective of this survey was to explore the current immunohematologic testing practices for the diagnosis of AIHA in India. This online survey consisted of 30 questions, covering the place of work, the number of AIHA cases encountered in the 3 preceding years, testing method(s), transfusion management, and so forth. Individuals representing 89 laboratories completed the survey; only 78 of which responded that AIHA testing was performed in their facility's laboratory. The majority of respondents agreed that the most commonly affected age-group comprised individuals of older than 20 years, with a female preponderance. Regarding transfusion management, respondents indicated that transfusion with "best-match" red blood cell units remains the most common practice. Column-agglutination technology is used by 92 percent of respondents as the primary testing method. Although a monospecific direct antiglobulin test is available at 73 percent of the sites, most of them have limited access to other resources that could diagnose cold or mixed AIHA. Merely 49 percent of responding laboratories have the resources to perform adsorption studies for the detection of alloantibodies. Furthermore, three-cell antibody screening reagents are unavailable at 32 percent of laboratories. In 72 percent of centers, clinical hematologists would prefer to consult a transfusion medicine specialist before administering treatment to AIHA patients. There is unanimous agreement regarding the need for a national registry. The survey data indicate wide variability in testing practices for patients with AIHA in India. Future studies are needed to focus on the feasibility and cost-effectiveness of different testing strategies for developing countries.

RESUMEN

BACKGROUND: Acute liver failure (ALF) following yellow phosphorous (YP) ingestion is similar to acetaminophen-induced ALF and it has become a public concern in our region. This study assessed low volume therapeutic plasma exchange (LV-TPE) efficacy in improving the transplant free survival in YP poisoning. METHODS: Adult patients with toxicology reports of YP and ALF requiring critical care were included in the study. LV-TPE was planned for three consecutive days and three more if required. Performed 1.3 to 1.5 plasma volume replacing with 0.9% normal saline, 5% human albumin solution, and fresh frozen plasma based on ASFA 2019 criteria. MELD score, laboratory parameters, LV-TPE details were captured. The study end point was clinical outcome of the patients. RESULTS: Among 36 patients, 19 underwent LV-TPE and 17 opted out of LV-TPE and they were included as a control arm. The MELD score was 32.64 ± 8.05 and 37.83 ± 9.37 in both groups. There were 13 survivors in LV-TPE group leading to a 68.42% reduction in mortality. The coagulation and biochemical parameters showed a significant percentage change after LV-TPE. Refractory shock, delay in initiating procedure and acidosis were independent predictors of mortality. CONCLUSION: A well-timed LV-TPE improves the survival of patients with ALF due to YP poisoning.

RESUMEN

Neutrophils play a vital role in the innate immunity by perform effector functions through phagocytosis, degranulation, and forming extracellular traps. However, over-functioning of neutrophils has been associated with sterile inflammation such as Type 2 Diabetes, atherosclerosis, cancer and autoimmune disorders. Neutrophils exhibiting phenotypical and functional heterogeneity in both homeostatic and pathological conditions suggests distinct signaling pathways are activated in disease-specific stimuli and alter neutrophil functions. Hence, we examined mass spectrometry based post-translational modifications (PTM) of neutrophil proteins in response to pathologically significant stimuli, including high glucose, homocysteine and bacterial lipopolysaccharides representing diabetes-indicator, an activator of thrombosis and pathogen-associated molecule, respectively. Our data revealed that these aforesaid stimulators differentially deamidate, citrullinate, acetylate and methylate neutrophil proteins and align to distinct biological functions associated with degranulation, platelet activation, innate immune responses and metabolic alterations. The PTM patterns in response to high glucose showed an association with neutrophils extracellular traps (NETs) formation, homocysteine induced proteins PTM associated with signaling of systemic lupus erythematosus and lipopolysaccharides induced PTMs were involved in pathways related to cardiomyopathies. Our study provides novel insights into neutrophil PTM patterns and functions in response to varied pathological stimuli, which may serve as a resource to design therapeutic strategies for the management of neutrophil-centred diseases.

RESUMEN

OBJECTIVES: To evaluate the return of blood components across different hospital areas, reasons for the same and suggest preventive strategies which might reduce out of controlled temperature storage (CTS) blood logistics and wastage. MATERIAL AND METHODS: A retrospective audit was carried out in the department of Transfusion Medicine from January 2019 to December 2022. Data related to returned blood components was compiled using departmental records and blood centre software entries. RESULTS: A total of 218 instances of returned components were noted and the total number of components returned were 442 (0.4% of all issued components) (38.4% (170) packed red blood cells, 16.2% (72) single donor cryoprecipitate concentrate, 19.6% (87) platelet concentrate and 25.5% (113) fresh frozen plasma). Components were returned back within 30 mins in only 27% (59/218) of all instances . Wards followed by high dependency units/intensive care units were noted to have the highest number of instances (86 (39.4%) and 69 (31.6%) respectively) with emergency department having the least,comprising 19 instances (8.7%). 77.9% (170/218) instances were observed for routine transfusion requests and 44.5% (97/218) of all instances could have been prevented by an appropriate clinical status assessment of the patient. CONCLUSION: Stakeholders such as clinicians, transfusion laboratory professional and nursing staff must take consolidated efforts to eliminate wastage of blood components. Instances of returned blood components can be targeted by the hospital quality team as a quality improvement project.

RESUMEN

BACKGROUND AND OBJECTIVES: ABO-incompatible transplantations allow patients to receive timely transplants. Isoagglutinin titration to ascertain levels of incompatible antibodies in the recipient is important in determining patient selection and transplant survivability. To find out the prevalent trends in India, the largest, first of its kind survey was carried out among the transplant centers regarding their practices in isoagglutinin titration. METHODS: The survey was drafted by a working group of Transfusion and Transplant Immunology specialists from six different centers. Data was obtained via the use of an online questionnaire. RESULTS: Results were categorized into four categories, Hospital information, Titration methodology, Role of transfusion specialists and cut-off titers. Most centers had a well-established solid-organ transplant program with considerable number of ABO-incompatible transplantations. Most centers performed isoagglutinin titration in Transfusion Medicine department. Column Agglutination Technique (CAT) was the most common method, using EDTA blood samples and freshly-prepared in-house pooled cells. Most centers had a turn-around time of less than 12 h. While the policy for ascertaining baseline and threshold titers is well-defined in ABO-incompatible renal transplants, variations from center to center still exist for ABO-incompatible liver transplants. Most centers required a Transfusion Medicine consultation for the patients before such transplants. CONCLUSION: With increasing ABO-incompatible kidney and liver transplants across the country, the role of Transfusion medicine specialists has become vital in pre-conditioning regimes enabling the viability and success of such transplants. This was a unique survey that provided a snapshot of current trends and practices of isoagglutinin titration for ABO-incompatible transplants in India.

RESUMEN

BACKGROUND: PBM metrics play a crucial role in assessing and monitoring the effectiveness of PBM programs in healthcare settings. The present study aimed to assess the indicators to achieve effective enforcement of PBM at a tertiary care referral hospital. SUBJECTS AND METHOD: A prospective observational study was conducted on patients admitted for elective surgery at a tertiary care referral centre. PBM metrics were developed and assessed for various parameters, including documentation, patient evaluation, blood ordering schedule, and appropriateness. Experts in transfusion medicine and haematology checked content validity. Eleven different parameters were analysed, and a score was assigned based on the performance. The outcome was categorized as poor, satisfactory, or good. RESULTS: The study included 612 patients meeting the inclusion criteria and recruited from Orthopaedics, General Surgery, OBG, Urology, and ENT departments. All departments completed pre-operative anaemia tests, with General Surgery and Orthopaedics conducting the most red cell transfusions. During the study, all of the blood units were used, and there was no waste. The C/T ratio was greater in the Departments of General Surgery, Urology, and Otorhinolaryngology. Pre-operative anaemia was found in 44.12% of patients, 44 patients had red cell transfusions, with 65% getting single-unit PRBC transfusions. All departments received a PBM score between 17-19, showing adequate PBM but with room for improvement. CONCLUSION: The current study utilized Patient Blood Management (PBM) metrics to critically assess the existing practices and identify the key gaps and areas for improvement in a tertiary care centre.

RESUMEN

ABSTRACT Introduction: Knowledge, Attitude and Practices (KAP) surveys prove beneficial to the transfusion services by providing an insight into the donors and, thus, aiding in mobilizing and retaining voluntary blood donors. We aim to study the knowledge, attitude and practices of donors towards blood donation in a pandemic setting. Methods: A cross-sectional observational study to assess the knowledge, attitude and practices of blood donors was conducted between June to and October 2020. Non-parametric tests (Mann - Whitney U and Kruskal - Wallis) were performed to evaluate the relation of knowledge, attitude and practices overall scores with age group, gender and history of blood donations (first us. repeat). The Chi-Square test/Fisher's Exact test was used to evaluate the differences in the distribution of Knowledge, Attitude and Practices items within the groups. Results: A total of 403 of 2,748 individuals who came for whole blood donation participated in the study. The mean age of the study population was 31.1years (SD ± 8.4 range: 18 - 58), with 75% of the donors donating for the first time. The fear of acquiring COVID-19 infection was perceived as a major reason for the eligible population not to donate. The overall knowledge, attitude and practice score among the donors was satisfactory, being 76.14%, with a significant association with age. The overall positive attitude and practices scores of blood donors were 85.48% and 78.04%, respectively. Conclusion: The KAP scores were satisfactory among the donors. Timely communication of the precautionary measures at blood centers to contain the spread of the COVID-19 infection and effective counseling would help in motivating and retaining blood donors.

RESUMEN

Background: In an ethnically diverse country like India, establishing a national rare donor registry is a massive challenge. We aimed to establish a regional rare donor registry at our center by screening the local donor population for rare phenotypes. Methods: Serological testing of O blood group donors was done using monoclonal antisera from Bio-Rad for 23 different blood group antigens, which include Rh subgroups (C,cE,e), Kell (K,k, Kpa, Kpb), P1, Duffy (Fya, Fyb), Kidd (Jka, Jkb), Lewis (Lea, Leb), Lutheran (Lua, Lub), H, M, N, S and s. We categorized the donors with rare blood phenotypes into two categories. Category-I: High-frequency antigen-negative phenotypes with a prevalence of less than 1% in our study population. Category-II: Multiple common antigen-negative phenotypes with a prevalence of less than 1% in our study population. Results: A total of 521 donors with blood group O, meeting the inclusion criteria among a total of 23567 were phenotyped for minor blood group antigens. Out of these, 85.6% (n = 446) were Rh D positive, and 14.4% (n = 75) were Rh D negative. The male-to-female ratio was 9:1. We had identified eight rare phenotypes in category-I and 18 rare phenotypes in Category-II according to the definition adopted in our study. We have noticed a significant decrease in turnaround time in providing rare blood to patients after implementing the registry. Conclusion: This is a first-of-its-kind rare donor registry established in South India. Establishing a national rare donor registry is the need of the hour in India.

RESUMEN

BACKGROUND AND OBJECTIVES: Repeated blood donation is a well-known cause of iron deficiency among donors. However, present scientific literature lacks comprehensive evidence regarding the impact of regular plateletpheresis procedures on body iron reserves. In this study, we aimed to detect and correlate iron deficiency (using iron indices) with the frequency of platelet donations. Additionally, we also analysed the correlation between other iron and haematological indices with serum ferritin to determine cost-effective parameters that may serve as an initial screening approach to determine which donors should be subjected to serum ferritin testing. MATERIALS AND METHODS: A total of 180 male participants from our platelet donor registry were enrolled in this observational cross-sectional study. Enrolment questionnaires were administered to eligible donors, and biological samples were collected during plateletpheresis donation. Biological tests such as complete blood count, reticulocyte indices, iron indices, vitamin B12 and folate were performed. RESULTS: Donors with ≥12 donations per year showed the highest prevalence of low ferritin (serum ferritin: 15-30 ng/mL) and absent iron stores (serum ferritin <15 ng/mL) (41.3% and 26.7%, respectively). Ferritin showed a significant negative correlation with recent (r = -0.346) and lifetime donations (r = -0.196). The efficacy of other indices for identifying iron depletion was much better using a serum ferritin value <15 ng/mL. CONCLUSION: Regular plateletpheresis donations can lead to varying severities of non-anaemic iron deficiency. Blood centres must regularly monitor frequent plateletpheresis donors (especially donors with more than 11 donations in a calendar year) and ideally maintain their serum ferritin above 30 ng/mL.

RESUMEN

BACKGROUND AND OBJECTIVES: The antigen frequencies vary across different regions and ethnic groups. Hence, we aimed to study the prevalence of blood group antigens in our population and to systemize the zone-wise prevalence of the same across India. MATERIALS AND METHODS: Regular voluntary O group blood donors were screened for 21 blood group antigens; C, c, E, e, K, k, Kpa, Kpb, Jka, Jkb, Fya, Fyb, Lea, Leb, Lua, Lub, P1, M, N, S, s, using commercially available monoclonal antisera by column agglutination technology. A literature search was performed to identify all the studies that reported blood group antigens prevalence to estimate the zone-wise prevalence of these antigens in the country. RESULTS: A total of 521 participants of 9248 O group donors meeting all the inclusion criteria were included. Among the study group, the male-to-female ratio was 9:1 with a mean age of 32.6 years (±10.01) ranging from 18-60 years. The majority of the donors 446 (85.6%) were D positive. The most common phenotypes among Rh, Lewis, Kell, Duffy, Kidd, Lutheran and MNSs were CcDee (34.93%), Le(a-b+) (61.80%), K-k+(98.27%), Fy(a+b-) 43.19%, Jk(a+b+) 42.61%, Lu(a-b+) ( 99.61%), M+N+ (48.17%), S-s+ (45.29%) respectively. The prevalence of D and E antigens was significantly lower in the South zone compared to other zones of India. CONCLUSION: Significant difference in the prevalence of blood group antigens is observed between the South and other zones of India. Zone-wise prevalence of blood group phenotypes is essential in the timely management of alloimmunized patients.

RESUMEN

BACKGROUND: Thromboembolic events are rare but one of the fatal complications in thalassemia. Assessment of the hypercoagulable state is not done regularly, and we have assessed the utility of Thromboelastography (TEG) for monitoring the activation of the coagulation pathway in patients with thalassemia. METHODOLOGY: A prospective single-center cohort study was conducted in a tertiary care set-up. Transfusion Dependent Thalassemia patients registered with the pediatric unit were screened for hypercoagulability using TEG during six months of the study period and followed up for three years for the development of thromboembolic events. Patient demographics, history of splenectomy, Serum ferritin levels and annual red cell transfusion requirement (mL/kg/year) were assessed. TEG parameters used were R time, K time, alpha angle, Maximum amplitude, Clot index, and Lysis 30. The thrombin generation test (V Curve) obtained from the first-degree derivate of the TEG velocity curve was also used for analysis. RESULTS: A total of 34 patients were recruited during the six months study period with an average age of 10.6 years ( ± 5.47). The average pre-transfusion hemoglobin level and the volume of packed red cells received were 7.24 g/dL and 152.82 mL/kg/year respectively. The TEG tracing was suggestive of a hypercoagulable state in 58.82% of patients. The mean values of angle (70.74), MA (64.16), CI (2.65) and TG (774.43) in TDT patients compared to age matched reference range (62.81, 57.99, 0.8, 577.83 respectively) was suggestive of prothrombotic changes. Annual blood transfusion requirement was negatively correlated with hypercoagulable status (-0.344, CI= -0.68 to 0.08). One out of 34 patients developed corona radiata infarct (with annual blood requirement; 112.7 mL/kg/Year). The risk to develop a hypercoagulable state appeared to be higher when the volume of RBCs transfused was less than 154 mL/kg/Year. CONCLUSION: TDT patients are at risk of developing thromboembolism, and screening with TEG may be useful to identify those at high risk.

RESUMEN

BACKGROUND: Autoimmune haemolytic anaemia (AIHA) is a decompensated acquired haemolysis caused by the host's immune system acting against its own red cell antigens. The aim of this national survey is to capture real-world data of clinical practices in AIHA by collecting responses from clinical haematologists across India. METHODOLOGY: In this cross-sectional study, a structured, 26-question online survey was conducted in India by few members of the special interest group in immunohaematology between January and March, 2022. The final survey consisted of questions covering place of work, amount of AIHA cases being evaluated by the haematologist over preceding years, basic demographic, clinical and laboratory features of the patients being treated under them etc. Descriptive statistical analysis was performed during the assessment. RESULTS: The survey response rate was 48.2% (53/110), 69.8% (37/53) have diagnosed and managed more than 10 AIHA cases in the last 3 years with a female preponderance. There was considerable variability in response. While 56.6% (30/53) of respondents do have the access to the facilities to subtype AIHA cases; 32.1% (17/53) of clinicians would prefer administering high dose steroids for 6 weeks or more in non-responding patients, and only 45.3% (24/53) would assess the risks of thrombosis in AIHA. There is unanimous agreement among the participants that health-related quality of life should be taken into consideration in patients and the need for a national registry of patients with AIHA in India. CONCLUSION: The current national survey showed that some aspects of AIHA management were consistent; others were less so, but also significant variations were observed in certain clinical practices, where the evidence base is limited. A joint effort is needed to establish a national patient registry by including both clinical haematologists and transfusion medicine specialists which could potentially standardise AIHA management and future research in India.

RESUMEN

Red cell exchanges (RCE) help in the treatment of complications of sickle cell anemia (SCA) by reducing the viscosity of blood and improving the oxygen-carrying capacity. We present a case of sickle cell crisis (SCC) managed with automated RCE and also reviewed the literature to assess the utilization and clinical efficiency of this therapy in India. A 19-year-old gentleman diagnosed with SCA presented with acute chest syndrome. Hemoglobin (Hb) was 8.8 g%, hematocrit (HCT) was 24%, and HbS was 90%. As there was worsening of symptoms with conventional management, the patient underwent two procedures of automated RCE. The clinical condition of the patient was improved, HbS was reduced to 16% and HCT was remained at 21% postprocedure. Articles on automated RCE in SCA conducted in India were reviewed and four articles were analyzed based on the search strategy. All the included articles concluded automated RCE as an effective procedure for complications of SCA. Common indication in India was SCA patients undergoing surgery as a prophylactic measure. Automated RCEs are promising as an acute treatment for indicated sickle cell complications. This therapy is underutilized in the Indian scenario, especially in patients with SCC.

RESUMEN

COVID 19 is caused by Severe Acute Respiratory Syndrome Corona Virus-2 which results in wide range of manifestations. Systemic hypercoagulation is a typical feature of COVID-19. We present a case of COVID-19 in whom TEG was performed on admission and hypercoagulability was diagnosed and hence patient was started on Enoxaparin sodium 6000 IU twice daily. TEG was repeated after 5 days which showed normal coagulation status and the patient was discharged without any thrombotic complications.

RESUMEN

Background: Overordering of blood has been a challenge faced by the blood bank staff. The present study addresses the role of maximum surgical blood ordering schedule (MSBOS) in optimizing the blood inventory management. Methods: The blood requests for elective surgical procedures from various surgical departments were reviewed to constitute MSBOS. Transfusion profile was assessed using crossmatch to transfused units (C/T) ratio, transfusion probability (TP), and transfusion index (TI). A cutoff of 0.3 and 5% value of TI and TP, respectively, was considered to decide on the type of crossmatch. The efficacy of MSBOS implementation has been determined prospectively by unpaired t test using SPSS software, version 20 (IBM, USA). Results: A total of 2674 patients were studied. Overall red cell usage rate was 15%. The comprehensive C/T ratio was 4.57. The C/T ratios for the various departments ranged from 1 to 8.5 (adjusted C/T ratio). Highest C/T ratio was observed for surgical procedures performed in the specialties of otorhinolaryngology and urology. A C/T ratio greater than 5 was noted in 30.4% of different types of surgical procedures. Of the 176 different types of elective surgical procedures studied, type and screen protocol was applicable for 75.5% (133) of the procedures. After implementation of MSBOS, the number of crossmatches reduced by 2152 and total working time saved in our laboratory is close to 75,320 man hours. Conclusion: MSBOS helps in identifying the common surgical procedures with low TP and is one of the efficient tools in preventing the overordering of the blood.
