Febrile non-haemolytic transfusion reaction occurrence and potential risk factors among the U.S. elderly transfused in the inpatient setting, as recorded in Medicare databases during 2011-2012

Incidence of acute transfusion reactions and associated factors among adult blood-transfused patients at Jimma University Medical Center, southwest Ethiopia: A cross-sectional study

Acute transfusion reaction is mainly related to the infusion of blood or blood products resulting at any time within a day of the intervention. It ranges from a non-specific febrile episode to a life-threatening intravascular hemolysis. The severity of the reaction and the degree of morbidity are usually related to the degree of ABO incompatibility and the volume of blood transfused. Therefore, this study aimed to determine the incidence of acute transfusion reactions and its associated factors in Jimma University Medical Center, southwest Ethiopia. Institution-based cross-sectional study was conducted from 1 October to December 30, 2020. A total of 384 transfused patients were followed in this study. Socio-demographic and clinical data were collected through a structured questionnaire. Baseline measurement and 24-hour periodic vital signs monitoring were conducted after each transfusion. Four milliliters of venous blood were drawn after transfusion intervention from each distrusted patient for complete blood count, blood group phenotype, direct antihuman globulin test (DAT), and crossmatching. Data were entered into Epi data version 3.1 and analyzed using Statistical Package for Social Science software (SPSS) version 20. Descriptive statistics, and bivariable and multivariable logistic regression were employed to test the association between independent and dependent variables. A P value ≤ .05 was considered to indicate statistical significance. Acute transfusion reactions were diagnosed in 5.7% of patients, with most of these reactions were febrile nonhemolytic reactions (63.6%) followed by allergic (36.4%) reactions with mild clinical manifestations (27.3%). Transfusion history, transfused blood that was kept for more than 13 days, abortion history, and number of transfused units (≥3 units of blood/blood component) have 3.3, 3.85, 4.2, and 3.9 times greater odds, respectively, besides their significant association with the incidence of acute transfusion reactions. Patients with a history of previous transfusion, abortion, multi-unit transfusion, and patients transfused with blood stored for ≥14 days should be closely monitored. Starting a hemovigilance system of monitoring, collecting, and evaluating data on adverse effects of blood transfusion locally and nationally will decrease the occurrence of acute transfusion reactions.

Review of haemovigilance at the Rabat Regional Blood Transfusion Centre in Morocco (2017-2021)

Introduction

blood transfusion remains an essential therapeutic intervention, but the occurrence of transfusion reactions makes its administration even more complex. Vigilant reporting of such reactions by recipients of blood products is essential for effective haemovigilance. This study aimed to determine the frequency and nature of transfusion reactions.

Methods

conducted over five years (2017-2021) at the Haemovigilance Department of the Rabat Regional Blood Transfusion Centre, this retrospective study exploited incident forms notified by health establishments and data from the regional blood transfusion centre's computer system.

Results

from 1 January 2017 and 31 December 2021, the Rabat Regional Blood Transfusion Centre distributed 435,651 labile blood products to various healthcare establishments, which reported 191 transfusion reactions involving 191 patients. The median age of the patients was 44.3 years, with an overall cumulative incidence of transfusion reactions of 0.44 per 1000 labile blood products delivered. The predominant reactions were non-haemolytic febrile and allergic reactions, accounting for 41.36% and 35.60% respectively. Grade 1 reactions accounted for 87% of all reactions recorded. During the study period, three deaths were recorded, with ABO incompatibility and transfusion-related acute lung injury (TRALI) accounting for two and one case respectively. Transfusion reactions involving erythrocyte components were significantly more frequent than those involving platelet and plasma components.

Conclusion

this study revealed a relatively low incidence of transfusion reactions (0.44%), dominated by non-haemolytic febrile and allergic reactions. Several levels of failure were identified, in particular under-reporting of reactions and inadequate training in transfusion practices and haemovigilance, as well as the need for an effective electronic transfusion reaction reporting system to facilitate reporting and identification of underlying problems and risk factors to improve the quality of transfusion care provided to patients.

Usefulness of palliative radiotherapy in reducing the frequency of red blood cell transfusion in patients with malignant tumor bleeding

Objective

We aimed to evaluate the usefulness of palliative radiotherapy in reducing the frequency of red blood cell (RBC) transfusions in patients with malignant tumor bleeding as a quantitative value to evaluate the hemostatic effect.

Materials and Methods

In this study, we conducted a retrospective review of patients visiting our department between June 2013 and April 2021. All patients underwent RBC transfusions for 30 days before the initiation of radiotherapy. We determined the overall survival (OS) time and RBC transfusion-free (RBCTF) time using statistical tests.

Results

In total, 21 patients were enrolled in our study, including 13 women and 8 men; the median patient age was 63 years (range: 32-82 years). After radiotherapy, 19 of the 21 patients had a decreased frequency of requirement for RBC transfusion compared to that before radiotherapy. Fourteen patients had achieved an RBCTF state 1 month after radiotherapy. The estimated 1-year OS and RBCTF rates were 36.3% (95% confidence interval [CI]: 14.2%) and 66.7% (95% CI: 42.5%-42.5%), respectively.

Conclusion

The present study revealed a reduction in RBC transfusion after palliative radiotherapy in patients with malignant tumor bleeding. We believe that reducing the frequency of blood transfusions in patients with terminal conditions would have significant clinical benefits.

Use of Diagnosis Codes to Find Blood Transfusion Adverse Events in Electronic Health Records

OBJECTIVE

Electronic health records (EHRs) and big data tools offer the opportunity for surveillance of adverse events (patient harm associated with medical care). We used International Classification of Diseases, Ninth Revision, codes in electronic records to identify known, and potentially novel, adverse reactions to blood transfusion.

METHODS

We used 49,331 adult admissions involving critical care at a major teaching hospital, 2001-2012, in the Medical Information Mart for Intensive Care III EHRs database. We formed a T (defined as packed red blood cells, platelets, or plasma) group of 21,443 admissions versus 25,468 comparison (C) admissions. The International Classification of Diseases, Ninth Revision, Clinical Modification , diagnosis codes were compared for T versus C, described, and tested with statistical tools.

RESULTS

Transfusion adverse events (TAEs) such as transfusion-associated circulatory overload (TACO; 12 T cases; rate ratio [RR], 15.61; 95% confidence interval [CI], 2.49-98) were found. There were also potential TAEs similar to TAEs, such as fluid overload disorder (361 T admissions; RR, 2.24; 95% CI, 1.88-2.65), similar to TACO. Some diagnoses could have been sequelae of TAEs, including nontraumatic compartment syndrome of abdomen (52 T cases; RR, 6.76; 95% CI, 3.40-14.9) possibly being a consequence of TACO.

CONCLUSIONS

Surveillance for diagnosis codes that could be TAE sequelae or unrecognized TAE might be useful supplements to existing medical product adverse event programs.

Analyzing real world data of blood transfusion adverse events: Opportunities and challenges

BACKGROUND

Blood transfusions are a vital component of modern healthcare, yet adverse reactions to blood product transfusions can cause morbidity, and rarely result in mortality. Therefore, accurate reporting of transfusion related adverse events (TRAEs) is paramount to improved transfusion practice. This study aims to investigate real-world data (RWD) on TRAEs by evaluating differences between ICD 9/10-based electronic health records (EHR) and blood bank-specific reporting.

STUDY DESIGN AND METHODS

TRAE data were retrospectively collected from a blood bank-specific database between Jan 2015 and June 2019 as the reference data source and compared it to ICD 9/10 diagnostic codes corresponding to various TRAEs. Seven reactions that have corresponding ICD 9/10 diagnostic codes were evaluated: Transfusion related circulatory overload (TACO), transfusion related acute lung injury (TRALI), febrile non-hemolytic reaction (FNHTR), transfusion-related anaphylactic reaction (TRA), acute hemolytic transfusion reaction (AHTR), delayed hemolytic transfusion reaction (DHTR), and delayed serologic reaction (DSTR). These accounted for 33% of the TRAEs at an academic institution during the study period.

RESULTS

Among 18637 adult blood transfusion recipients, there were 229 unique patients with 263 TRAE related ICD codes in the EHR, while there were 191 unique patients with 287 TRAEs identified in the blood bank database. None of the categories of reaction we investigated had perfect alignment between ICD 9/10 codes and blood bank specific diagnoses.

DISCUSSION

Multiple systemic challenges were identified that hinder effective reporting of TRAEs. Identifying factors causing inconsistent reporting between blood banks and EHRs is paramount to developing effective workability between these electronic systems, as well as across clinical and laboratory teams.

Preventing adverse reactions in pediatric transfusions using washed platelet concentrate

Blood transfusion is an important form of supportive care in children; however, transfusion-associated adverse reactions (TARs) are a problem. As with adults, allergic transfusion reactions (ATRs) and febrile non-hemolytic transfusion reactions (FNHTRs) are major TARs, and the frequency of ATRs caused by platelet concentrate (PC) tends to be particularly high. The plasma component of the blood product is thought to be a major factor in the onset of TARs such as ATR and FNHTR. By contrast, in children, age, underlying disease, and number of blood transfusions may be relevant patient-related factors. Although acetaminophen or diphenhydramine may be used prophylactically to prevent TARs, there is no clear evidence of their effectiveness. Volume-reduced PC is used to prevent TARs; however, it may be difficult to maintain the quality of platelets. Plasma-replaced PC stored with platelet additive solution raises the concern that TARs cannot be completely prevented by residual plasma. Washed PC removes most of the plasma, so it can effectively prevent ATR and FNHTR. The recent development of platelet additive solution [M-sol, bicarbonate Ringer's solution supplemented with acid-citrate-dextrose formula A (BRS-A)] in Japan has enabled the maintenance of the quality of platelets for long periods. The clinical use of washed PC in Japan has therefore progressed. Washed PC with M-sol or BRS-A for pediatric patients can effectively prevent TARs without diminishing the transfusion effect. The supply of washed PC has begun from the Japanese Red Cross Society, and it has become possible to use washed PC at all medical institutions in Japan.

Identifying and Understanding Transfusion Reactions in the Oncology Population

OBJECTIVES

To provide an overview of transfusion reactions, their underlying pathophysiology, clinical presentation, and recommendations for nursing management.

DATA SOURCES

We researched peer-reviewed journal articles, book chapters, Internet, and lecture proceedings.

CONCLUSION

Transfusion reactions are adverse reactions to blood products frequently seen in the oncology population and can significantly vary in severity and etiology. Oncology nurses are in a critical position to assist with prevention, early detection, and time-sensitive treatment of transfusion reactions.

IMPLICATIONS FOR NURSING PRACTICE

The oncology nurse's comprehensive understanding of possible transfusion reactions and management recommendations is key for optimal care of the oncology patient.

Sex- and Gender-Related Factors in Blood Product Transfusions

Blood products are indicated for a plethora of conditions in several settings, with a variety of products available for transfusion, from highly processed specific components to whole blood. Matching the donor product to the recipient is crucial in avoiding serious transfusion reactions, with the extent of matching depending on the physiological need, setting, and product. There are important factors related to sex and gender differences in donated blood products, adverse reactions to those products, interplay with underlying pathology, as well as sociocultural differences in the collection. This article will review key sex- and gender-specific research related to the use of blood products with an emphasis on the acute care setting.

Proportion of Acute Transfusion Reaction and Associated Factors Among Adult Transfused Patients at Felege Hiwot Compressive Referral Hospital, Bahir Dar, Northwest Ethiopia: A Cross-Sectional Study

Introduction

Acute transfusion reactions are adverse events occurring within 24 hrs of transfusion and cause simple-to-severe complications. They may vary with the blood component transfused and recipient factors. In Ethiopia, there is a limited evidence about the incidence and associated factors of transfusion reactions.

Objective

To determine the proportion of acute transfusion reactions and associated factors among adult transfused patients.

Methods

A total of 384 study participants were included in the study. Structured questionnaires were used for socio-demographic and past medical history data collection. Vital signs were measured as a baseline for every study participants and monitored and followed for 24 hrs. Laboratory tests like complete blood count, direct anti-human globulin test and urine hemoglobin were done as a baseline for suspected patients. Cross-match, blood grouping, and blood culture for patients and donors sample were also done for suspected patients. Descriptive statistics, bivariable and multivariable binary logistic regression were analyzed using SPSS version 20. P-value of <0.05 in the multivariable model was considered as statistically significant.

Results

Acute transfusion reactions were observed in 5.2% of patients. Of total cases of acute transfusion reaction, the majority developed allergic reactions (65%) and febrile non-hemolytic transfusion reaction (30%). It was significantly associated with transfusion history (AOR=3.4; 95% CI: 1.2–9.7), abortion history (AOR=5.0; 95% CI: 1.5–16.4), longer blood storage time (AOR=5.1; 95% CI: 1.7–15.2) and receiving three or more unit of blood (AOR= 4.1; 95% CI: 1.5–11.2).

Conclusion

Acute transfusion reactions were observed in 5.2% of patients (allergic reactions (65%), febrile non-hemolytic transfusion reaction (30%) and alloimmunization (5%)). Patients with a history of transfusion, abortion, transfused with blood stored ≥14 days and multi-transfused patients should be closely monitored.

A retrospective cost analysis of the frequency and cost of transfusion premedications

BACKGROUND

Acetaminophen and diphenhydramine are routinely administered to prevent febrile non-hemolytic and allergic blood transfusion reactions despite multiple randomized controlled trials demonstrating that this practice lacks efficacy. As a result, patients are exposed to the adverse effects of these medications and their financial burdens with no expected benefit. The aim of this study was to quantify the frequency and cost of transfusion premedications in patients with acute myeloid leukemia (AML).

STUDY DESIGN AND METHODS

This was a retrospective study of patients with AML admitted to Vanderbilt University Medical Center (VUMC) for induction chemotherapy between January 2008 and December 2016. Data were collected on the number of platelet and packed red blood cell (PRBC) transfusions each patient received during the initial inpatient encounter for AML, as well as on the administration of premedications prior to each transfusion.

RESULTS

During the 9-year study period, 948 AML patients received a total of 19,820 transfusions. Of these, 30% were preceded by oral diphenhydramine, 8% by intravenous diphenhydramine, and 39% by oral acetaminophen. The percentage of patients that received a transfusion preceded by a premedication increased over the study period (p = 0.03), as did the percentage of transfusions preceded by a premedication (p = 0.02). The total unadjusted cost of pre-transfusion medications to the institution during the study period was $50,309.77, or $52.67 per patient with AML. The cost of premedications per patient did not increase over the study period (p = .45).

CONCLUSIONS

Routine transfusion premedication administration is common in AML patients and not well-supported by available evidence.

Pre-operative autologous blood donation and transfusion-related adverse reactions: A 14-year experience at a university hospital

OBJECTIVE

The objective of this study was to determine the rate of adverse reactions to pre-operative autologous blood donation (PAD) transfusion in a single institution over a 14-year period.

STUDY DESIGN AND METHODS

Between January 2003 and December 2016, we investigated adverse reactions to PAD transfusion and compared them with those to allogeneic blood transfusion in Juntendo University Hospital. Adverse reactions were categorized according to the definition proposed by the International Society of Blood Transfusion (ISBT) Working Party on Haemovigilance.

RESULTS

A total of 178,014 blood components were transfused during the study period, of which PAD transfusions were 13,653 (8%), whereas allogeneic blood transfusions were 164,361 (92%). The number and rate of adverse reactions to PAD transfusion were 16 and 0.1%, whereas those of allogeneic blood transfusion were 1075 and 0.7%, respectively. The rate of adverse reactions to allogeneic blood transfusions excluding platelet transfusion was 0.3%, being significant (p < 0.01) against PAD transfusion. Among 16 adverse reactions to PAD transfusion, the most common was febrile non-hemolytic transfusion reaction (FNHTR) at 12 (75%), followed by allergic reaction at 4 (25%). The severity of adverse reactions to PAD transfusion was Grade 1 (non-severe) in all cases. With regard to blood component types, 16 adverse reactions involved: 12 cases of whole blood PAD, 2 of frozen PAD, and 2 of autologous fresh-frozen plasma.

CONCLUSIONS

Non-severe adverse reactions were observed on PAD transfusion at a rate of 0.1% at our institution.

Blood transfusion in elderly patients with chronic anemia: a qualitative analysis of the general practitioners' attitudes

Background

Blood transfusion in chronic anemia is not covered by guidelines specific to older adults. When they consider that this treatment is necessary in elderly patients, French general practitioners (GPs) contact a hospital specialist to plan a transfusion.

Methods

Twenty French GPs were questioned individually regarding their approach to blood transfusion using semi-structured interviews. Each interview was recorded, typed up verbatim and then coded using an inductive procedure by theme, in a cross-over design (two researchers) in two phases: analysis and summary, followed by grouping of the recorded comments.

Results

The criteria for transfusion were hemoglobin level < 8 g/dL and cardiac comorbidities. Some geriatric issues, such as cognitive disorder or dependence, were considered, either as aspects of frailty favoring transfusion or as markers of reduced life expectancy that limit care. Falls and fear of an unpleasant death from anemia prompted GPs to order blood transfusion. The patient’s family provided guidance, but the patient was not routinely consulted. The specialists were rarely asked to participate in decision making. GPs’ perceptions were ambivalent: they considered transfusion to be extraordinary and magical, but also pointless since its effects are transient.

Conclusion

The decision to give a transfusion to an elderly patient with chronic anemia is deemed complex, but GPs seem to take it alone, sometimes guided by the patient’s family. The drawing up of an advance care plan could help involve the patient in decision making.

Adverse Reactions to Transfusion of Blood Products and Best Practices for Prevention

Transfusion, a common practice in critical care, is not without complication. Acute adverse reactions to transfusion occur within 24 hours and include acute hemolytic transfusion reaction, febrile nonhemolytic transfusion reaction, allergic and anaphylactic reactions, and transfusion-related acute lung injury, transfusion-related infection or sepsis, and transfusion-associated circulatory overload. Delayed transfusion adverse reactions develop 48 hours or more after transfusion and include erythrocyte and platelet alloimmunization, delayed hemolytic transfusion reactions, posttransfusion purpura, transfusion-related immunomodulation, transfusion-associated graft versus host disease, and, with long-term transfusion, iron overload. Clinical strategies may reduce the likelihood of reactions and improve patient outcomes.

The effect of ambient exposure to PM2.5 on the transfusion usage of blood components and adverse transfusion reactions in the haze weather

BACKGROUND

Accumulating evidence has shown that ambient exposure to PM_2.5, especially in the haze weather, increased the risk of various diseases. However, the association of air pollution status with blood transfusion utilization and the prevalence and severity of adverse transfusion reactions remain to be clarified.

MATERIALS AND METHODS

The data of monthly transfusion usage of blood components, adverse transfusion reactions, as well as PM_2.5 and PM₁₀ levels from 2013 to 2015 were obtained.

RESULTS

During the study interval, both PM_2.5 and PM₁₀ levels were significantly increased in the haze weather when compared with the non-haze weather. The utilization of total blood components per patient-month in the haze weather was prone to be increased when compared with that in the non-haze weather (13.28 ± 1.66 vs. 12.33 ± 1.30, p = 0.068). The usage of RBC products per patient-month in the haze weather was significantly increased when compared with that in the non-haze weather (4.39 ± 0.39 vs. 4.07 ± 0.30, p = 0.009). There was no obvious difference between the haze and non-haze weathers for the usage of platelet and plasma products per patient-month. Besides, no definite differences of the prevalence and severity of transfusion-associated adverse reaction were observed between the haze and non-haze weathers.

CONCLUSION

Our study first indicated that transfusion utilization, particularly the RBC products, was significantly increased in the haze weather when compared with that in the non-haze weather. There was no obvious association of air pollution with the prevalence and severity of adverse transfusion reactions and further research is required.

Haemovigilance of reactions associated with red blood cell transfusion: comparison across 17 Countries

BACKGROUND AND OBJECTIVES

The recent establishment of the National Healthcare Safety Network Hemovigilance Module in the United States affords an opportunity to compare results with those of other developed nations.

MATERIALS AND METHODS

Using data from national haemovigilance systems, reactions associated with red blood cell (RBC) transfusion and residual risks of transfusion-transmitted infectious diseases were assembled from 17 nations. Country-specific rates of adverse events were pooled using random-effects Poisson regression.

RESULTS

Febrile non-haemolytic and delayed serologic transfusion reactions were the most frequent adverse events reported after RBC transfusion, occurring in 26 patients per 100 000 RBC units and 25 patients per 100 000 RBC units administered, respectively. Rates of allergic, febrile non-haemolytic and delayed haemolytic transfusion reactions in the United States were significantly greater than the pooled rates from other countries. Frequencies of adverse events generated from the national haemovigilance programme in the United States were considerably lower than when obtained through active surveillance.

CONCLUSION

Haemovigilance reports of adverse events in the United States are comparable to, or greater than, reports from other developed countries. Rates generated from haemovigilance programmes are lower than those obtained through active surveillance. The lack of universal leucoreduction of RBC units may be a contributing factor to the higher rate of some adverse events in the United States.
