To study the effect of 'Covishield' vaccination on pre-donation platelet counts of plateletpheresis donors

ABSTRACT Introduction: Approximately 55.52% of the Indian population had been fully vaccinated by Jan. 2022, since its first roll out on January 16, 2021. A few concerns were raised concerning the Covishield vaccination related to thrombotic thrombocytopenia. Apheresis-derived platelet concentrates are frequently required in a plethora of clinical situations and post-vaccination decrement of platelet counts might lead to increased deferral of the plateletpheresis donors. Objectives. The aim of the study was to discover the effect of the Covishield vaccination on deferral rates of plateletpheresis donors. Methods: Blood samples were collected from the potential platelet donors for the completion of the standard questionnaire for the complete blood count. The data collected were tabulated in the MS Excel spreadsheet and the biostatistical analysis was performed with the SPSS v23. A p-value of < 0.05 was taken as significant. We compared this data with age-and sex-matched controls. Results: The mean age of cases and controls was 29.69 ± 8.57 and 30.15 ± 7.11, respectively. There was a significant difference in platelet counts of cases (188496.35 ± 72065.66/cumm) and controls (269524.50 ± 53981.60/cumm). Furthermore, donors who received one dose had higher platelet counts of 248676.47 ± 80075.24/cumm than those who received both doses of vaccine (179970.83 ± 66773.73/cumm). The difference in deferral rates between the two groups was remarkable (34.7% vs. 0.9%, with the p-value < 0.001). Conclusion: Vaccination certainly increased the deferral rates of plateletpheresis donors due to low platelet counts. Average platelet counts were low in fully vaccinated individuals, however, the platelets returned to normal counts as the post-vaccination days progressed.

At the same time, the design utilized a hospital consignment warehouse. The comprehensive promotion of this practice by the hospital saved costs, improved the overall efficiency of the entire business process of orthopedic high-value consumables, and met the requirements of relevant policy supervision and hospital refined management.

Impact of the novel coronavirus disease and lockdown on the packed red blood cells inventory management: An experience from a tertiary care oncology center in Western India

ABSTRACT Introduction The novel coronavirus disease has disrupted blood transfusion services worldwide. Despite blood transfusion services taking several precautionary measures to minimize the risks of COVID-19 during blood donations, donors became anxious regarding the risk of the COVID-19 infection during the donation and the blood transfusion services was facing the inevitable hazard of blood shortage. Methods The study was conducted at a tertiary care oncology hospital-based blood transfusion services and included analysis of blood donations, packed red blood cell units requirements, and packed red blood cell inventory in the pre lockdown and lockdown phase. New COVID-19 standard operating procedures with enhanced safety guidelines and donor confidence-building measures were implemented at the blood transfusion services. Results The total number of average monthly blood donations decreased in lockdown but the decrease was not statistically significant (238.5 vs. 197.8, P = 0.391). The requisitions for the packed red blood cell cross-matches (722.5 vs. 329.0, P = 0.001) and the packed red blood cell utilization (176.5 vs. 103.3, P = 0.028) for the hospital patients also decreased significantly due to the lockdown. In the lockdown phase, an expressive number of packed red blood cell units were outdated due to the unprecedented fall in the number of patients. In the post-lockdown phase, the packed red blood cell inventory was optimized with decreased outdating via a comprehensive approach. A special emphasis was given to the in-house donations. A second partial lockdown also decreased the blood donations. Conclusion Confidence-building in blood donors and the resolution of logistical issues were crucial for the efficient packed red blood cell inventory management in the lockdown. Implementation of COVID-19 preventive measures helped in the blood donor and blood transfusion services staff safety.

Blood inventory changes and blood supply situation during COVID-19 / 中国输血杂志

【Objective】 To evaluate the impact of COVID-19 epidemic prevention and control on blood collection and supply, so as to accumulate experience for future similar public events. 【Methods】 The annual inventory before Spring Festival holiday, the supply of red blood cells and apheresis platelets during Spring Festival (from New year′s Eve to lunar January 6th) and the collection and supply units 3 months after the Spring Festival (the lunar January 7th to April 8th) during 2017 to 2020 were analyzed to evaluate the impact of the epidemic on blood collection, supply and inventory management. 【Results】 The inventory and its proportion in 2020 decreased to 14 594 U and 23.89%, compared with those in 2018 (16 095 U, 26.34%) and 2019 (16 301 U, 26.68%), with significant differences (P<0.05). The COVID-19 epidemic(3-month-post Spring Festival in 2019 and 2020) reduced the blood collection in urban areas(28 613 U and 19 901 U) and group donation (17 443 U and 5 332 U), but rasied blood collection in towns (43 184 U and 50 963 U). The clinical blood consumption in year 2017, 2018, 2019 and 2020 was 80 339 U, 79 359 U, 87 581 U and 74 986 U, respectively, decreasing due to the epidemic (P<0.05), with a small amount(229 U) of red blood cell discarding owing to expiration. The collection and supply of apheresis platelets were minimally affected by the epidemic. 【Conclusion】 The epidemic had a direct/indirect impact on blood collection, blood supply and inventory management, except for apheresis platelets collection and supply. It suggests that the characteristics of COVID-19 prevention and control measures can be used as references for future precise organization and targeted recruitment of blood resources in case of the similar emergencies. Close communication with clinical departments contributes to the safeguard of emergency transfusion and the prevention of blood expiration.

The Experience of Applying an Australian Red Blood Cell Safety Stock Calculation to Korean Hospitals / 대한수혈학회지

BACKGROUND: The management of red blood cell inventory in hospital's blood bank is crucial. The Australian Red Cross Blood Service developed a RBC safety stock calculation method (abbreviated as the ‘Australian formula’). In this study, we applied this method to four Korean hospitals to calculate the safe RBC stock level. METHODS: The hospitals included in this study were three tertiary teaching hospitals and one teaching hospital. The number of hospital beds in these hospitals were 1093, 1330, 1400, and 854, respectively. The data were collected from the Korea Blood Inventory Monitoring System of Centers for Disease Control & Prevention. The target/minimal/maximal RBC inventory levels and inventory days (inventory level/average daily usage) by ABO blood types were calculated using the daily red cell transfusion, wastage, and supply data between May and October 2016. RESULTS: The enrolled hospitals showed different levels for the target/minimal/maximal RBC inventory according to each blood group. The average of RBC inventory days in the four hospitals was 4.2 days. For each blood group, RBC inventory days were 3.2~4.4 days for O blood group type, 3.5~4.7 days for A blood group, 3.9~4.5 days for B blood group, and 3.9~5.5 days for AB blood group. CONCLUSION: Because the optimal RBC inventory levels are different depending on the hospital characteristics and the ABO blood group, it is necessary to set the RBC inventory levels for each hospital distinctly. The data obtained in this study will help manage blood product inventory in various hospital blood banks.

Improvement of the In-hospital Inventory Period of Red Blood Cells by Reducing the Inventory Levels in the Hospital Blood Bank / 대한수혈학회지

BACKGROUND: The clinical importance of transfusing older RBCs versus newer RBCs remains controversial, with some studies identifying adverse consequences and others have not. We evaluated the age of RBCs transfused in a Korean tertiary hospital and the improvement of the in-hospital inventory period by reducing the level of inventory in the hospital blood bank. METHODS: The packed RBCs that were issued from November 14th, 2009 to November 13th, 2010 were analyzed. The inventory level was reduced in May 14th, 2010. We compared the total inventory period, the in-hospital inventory period and the pre-delivery period between before inventory reduction and after inventory reduction. RESULTS: The in-hospital inventory period of the packed RBCs was significantly shortened after inventory reduction (6.0 day vs. 4.0 day, P<0.0001). Because the pre-delivery period was prolonged due to a temporary increase of blood donations, the total inventory period was not shortened. CONCLUSION: This study provides that the in-hospital inventory period can be improved by reducing the inventory levels in the hospital, but further studies are required to decide what the adequate inventory levels should be.
