Introduction : Selection of proper donor according to stringent selection criteria is the prerequisite for safe blood transfusion practice. It is widely known that a large number of blood donors are deferred for different reasons.Objective : The aim of present study is to evaluate the incidence and different reasons of blood donor deferral in atertiary care hospital.Methodology : This retrospective cross-sectional study was carried out in Transfusion Medicine and Clinical Haematology Department of BIRDEM General Hospital, Dhaka, during the period from July 2016 to June 2017.The blood donor of either sex attending the mentioned department were selected purposively and categorized into four groups according to their age for this study. Donors were selected and deferred by medical officer according to national guideline. Deferred blood donors were recorded in register book and were analyzed retrospectively.Results : In current study, 1152 blood donor (8.8%) were deferred attending for allogeneic blood donation during the study period. Out of 13082 registered blood donor 11961were male (91.43%) and 1121 were female (8.57%) and deferral rate was 2.37 times more in female. Majority of the deferred donors (55.38%) were under the age of 40 where 26.82% were in between 40-49 years and 17.8% were in the range of 50 years and above. Age range of highest deferred donors (32.20%) was between 30-39 years. The number of temporary and permanent deferral were 836 (72.57 %) and 316 (27.43%) respectively. Anaemia (33.01%), underweight (21.53%) and hypotension (17.34%) were the most common reason of temporary deferral. Chronic uncontrolled hypertension (42.4%), donors with medication (16.77%) and asthma (15.18%) was the most common cause of permanent deferral.Conclusion : The deferral rate was low and most of the deferred donors were young adult. Temporary deferred donors were higher than permanent deferred donors. The most common reasons for temporary deferral were anemia, underweight and hypotension. Permanent deferral causes were chronic uncontrolled hypertension, donors on medication for various reason and asthma. Donors should be informed with a clear message on their deferral status. It is important to determine the rate and causes of donor deferral for the safety of blood transfusion and to guide the recruitment efforts for safe blood transfusion and to avoid the permanent loss of blood donors.
Background:Allergic transfusion reactions (ALTR) are very common complication of blood transfusion. Advances in transfusion medicine have significantly decreased the incidence of ALTR; however, ALTR continue to be burdensome for transfusion dependent patients. It increases their existing sufferings. Allergic reaction is more common in platelet concentrate transfusion because stored platelet concentrate supernatants (PCSNs) accumulate striking levels of biological response modifiers (BRMs) during storage. Objective: To determine the risk factors of allergic reactions in platelate concentrate transfusion. Method: It is a case control study enrolled a total of 64 diagnosed case of aplastic anaemia receiving transfusion of platelet concentrate at Department of Transfusion Medicine, BSMMU, Dhaka, from May 2015 to April 2016. Among them 32 case of aplastic anaemia having allergic reaction due to transfusion of platelet concentrate was considered as group I (case) and rest 32 patients not developed allergic transfusion reaction due to transfusion of platelet concentrate was considered as group II (control). Patients age belong to 5 - 50 years and both sex and also patients getting transfusion of plate late concentrate were enrolled in this study. Statistical analysis: Statistical analyses were carried out by using the Statistical Package for Social Sciences version 20.0 for Windows (SPSS Inc., Chicago, Illinois, USA). Chi-Square test, Odds ratio with 95% CI used to analyze the categorical variables, shown with cross tabulation. Student ttest used for continuous variables. Significant value of 'p' was decided to be at a level of 0.05 in two tailed tests. Result: The mean age was found 22.1±11.58 years in group I and 23.5±3.8 years in group II. Twenty four (75.0%) patients were male in group I and 17(53.1%) patients in group II. Almost twenty (62.5%) patients come from urban area in group I and 19(59.4%) in group II. In group I, thirty two (100.0%) patients had urticarialrash, 100.0% had itching, 37.5% had angioedema, 3.1% had cough, 3.1% had chest pain, 3.1% had respiratory distress, 3.1% had fever and 3.1% had vomiting. Almost twenty(62.5%) patients had tachycardia (>100 bpm) in group I and all patients had normal pulse in group II.Thirty two (100.0%) patients had normal blood pressure in both group. In group I, 31(96.9%) patients developed mild allergic reaction, 3.1% moderate allergic reaction. Majority (40.6%) patients belonged to age 16-30 years in present allergic transfusion reaction and 11(34.3%) in absent allergic transfusion reaction. Most (40.6%) of the patients was found blood group B in present allergic transfusion reaction and 11(34.4%) in absent allergic transfusion reaction. Multiple unit of PC transfusion increases 3.69 times risk to develop allergic transfusion reactions with 95% CI 0.99 to 14.44%.Platelet concentrate storage>3daysincreases 5.95timesrisktodevelopallergic transfusionreactionwith95%CI1.75to21.09%. Conclusion: Multiple unit (≥2) transfusion and Platelet concentrate storage >3 days were significantly (p<0.05) associated with allergic transfusion reactions but no significant association was found between allergic transfusion reactions with age and Blood group
Introduction: Blood requisition form (BRF) analysis is one of the most efficient and effective approaches to assess and monitor rational use of blood and its product. BRF is the first line of communication between the clinicians and transfusion medicine specialists which helps to recognize and evaluate inappropriate use of blood. This issue is frequently underrated by the clinicians which results in increased risk of inappropriate transfusion. The current study is aimed to examine the pattern of completion of blood requisition forms and to ensure safe blood transfusion. Materials and methods: This cross sectional prospective study was conducted from January 2020 to December 2021, at the Department of Transfusion Medicine, Sir Salimullah Medical College Mitford Hospital, Dhaka, Bangladesh. A total of 32,133 blood requisition forms that were submitted during the study period were compiled and reviewed anonymously. The data were analyzed using Microsoft Excel. Results: During the study period, a total of 32,133 Blood requisition forms were analyzed. Only 15.2% of these forms were duly completed. Rest of the forms had one or more important parameters left blank. The most common incomplete BRF items were the clinical history or differential diagnosis of the patient (52.66%), presumed date and time of transfusion (95.19%), previous transfusion history (95.9%), and referring doctor’s name and designation (88%). Blood requests were more for females (52.02%) than males (47.98%) during the period. Requisitions were more for adults (90%) than pediatric patients. Conclusion: The current study provides evidence that the rate of completion of BRFs is not satisfactory. The request forms evaluated were not covering acceptable demographic and clinical data of the patients. Both the Hospital Transfusion Committee (HTC) and the Department of Transfusion Medicine can help to improve and standardize transfusion practice by working together.

Background: Our aim is to evaluate reasons of donor deferral in tertiary care hospital to nd new disease distribution, any areas of negligence in part of donor or history taking physicians and human errors which could be easily correctable and benecial for donors to remain healthy and provide safe blood. Methodology: This is a retrospective analytic study carried out during the period of January to December 2015 at Department of Transfusion Medicine, Sir Salimullah Medical College and Mitford Hospital. After preliminary registration, each donor was either selected or deferred by medical ofcers. The donor selection and deferral criteria were according to the standard operating procedure. Detailed information of reason of deferral was recorded. Results:Among 10056 registered donors, 9453 (94.004%) were eligible for donation and 603 (5.996%) blood donors were deferred due to various reasons. Male donors were 7526 (74.84%) more than female 2530 (25.16%). Females (60.03%) were found to have higher deferral rate than male population (39.97%). Low hemoglobin was found to be leading cause constituting 17.58% followed by hypertension 15.26%, medications 12.11% and underweight 11.28%. Conclusion: Deferral may discourage the donor for subsequent donations, especially young rst time donors. Deferred donors should be properly counseled and educated for probable future donations. By knowing the causes of deferral we can take further steps to prevent those causes and can preserve precious blood and blood components.
