Blood Inventory Management During COVID-19 Pandemic Using a Simple Mathematical Tool: A Two-Year Study from a Tertiary Care Hospital in North India.

Multiple recurrent waves of the coronavirus disease 2019 (COVID-19) resulted in major fluctuations in blood supply and demand, which presented a major challenge for the blood centres to maintain adequate blood inventory. Hence, the primary aim of the present study was to determine whether safety stock as a simple mathematical tool can be used to maintain optimum blood inventory to meet all blood demands. The secondary aim of the study was to test whether daily blood stock index (DBSI), which was a novel index developed by the authors and derived from the calculated safety stock, can be used to minimize blood wastage due to the outdating of packed red blood cells (PRBC)/whole blood (WB) units. The present study was a descriptive, cross-sectional study conducted from 1st October 2019 to 31st December 2021 at a blood centre of a tertiary care hospital. For the purpose of data analysis, the time period of study was divided into 7 periods signifying different phases during the COVID-19 outbreak. Data of PRBC/WB (referred to as red cell) collection, red cell issue and the daily red cell stock were collected for these 7 time periods. Safety stock, percentage of out-dated whole blood/packed red blood cell units (OB) and DBSI were calculated based on the data extracted. Red cell collection as well as red cell utilization decreased during the 1st as well as the 2nd wave of the COVID-19 outbreak. The blood centre was able to meet the blood demand of the hospital at all times, as the daily average red cell stock remained above the calculated safety stock during all periods. OB (12.4%) and DBSI (2.3) were highest during the lockdown period of second wave of COVID-19 outbreak (period E). A strong direct relationship was seen between OB (dependent variable) and DBSI (predictor variable) [R = 0.79; p = 0.03]. Firstly, safety stock is a simple, user-friendly mathematic tool which can be used for efficient blood inventory management not only at times of a pandemic/disaster but also during routine times. Secondly, DBSI is a logical and empirical tool to reduce OB units and consequently reduce blood wastage.

Reviewing the Ethical Concerns of the Convalescent Plasma Therapy in COVID-19.

The understanding of coronavirus disease 2019 (COVID-19) is evolving periodically. There is also a marked increase in COVID-19 patients' demand for the provision of COVID-19 convalescent plasma (CCP) therapy. With the review of the literature, the stage of speculation is quickly moving towards conformity, with the interim guidelines given by the Food and Drug Administration (FDA) in the United States, United Kingdom's blood transfusion services, Saudi's FDA, and the Indian Council for Medical Research, in addition to the European health authorities. It is prudent to address the ethical concerns that merit consideration while harvesting and utilizing CCP as a therapeutic tool in local hospital setting.

Exploration of COVID-19 related fears deterring from blood donation in India.

INTRODUCTION: The coronavirus pandemic (COVID-19) has impacted and pushed the healthcare settings to extremes across the globe. It was extremely challenging to sustain blood donation, and strategies could be formulated on knowing fears hindering blood donation. METHODS: A cross-sectional survey using Google Forms® through WhatsApp and email after obtaining the ethical clearance. The survey questionnaire was validated for content using the Delphi technique, and pilot tested for finalization. RESULTS: The survey was attempted by 1066 participants, and 749 participants who had not donated since pandemic were included in the study. A little more than half, 415 (55%) reported either one or more than one fear during the pandemic which hindered blood donation. They reported lack of confidence in the safety measures at the hospitals and fear of transmitting infection to family, in 415 (55%) of the participants each, respectively. The fear of COVID-19 hospital infection risk and hospital entry was statistically significant across the age groups that are eligible for blood donation. CONCLUSIONS: The clear and dedicated confidence building measures to sustain blood donation using all communication modalities clearly emerge as the most important strategies to augment blood donation in the COVID-19 pandemic. The measures should include information about implementation of safety measures to mitigate COVID-19 transmission at the blood centres and that the act of blood donation does not increase risk of COVID-19 and therefore the risk of transmission of infection to family.

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.

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.

The blood supply management amid the COVID-19 outbreak.

Due to the government's early intervention such as mass lockdown and curtailment strategies towards mass gatherings, amid the COVID-19 outbreak, the organization of the voluntary blood donation camps have been suspended. It's most significant impact on the blood community has been a dramatic decrease in the number of blood donors. Therefore, our blood stock has almost dried up and put our inventory in a state of jeopardy. Additionally, all the elective surgeries and non-urgent clinical interventions have also been deferred during this time. This has led to a drop in the blood collection, demand as well as the issue at our blood center. With this backdrop, we intended to assess the effect of this mass lockdown on our blood supply management, particularly in two phases [phase-I prior to the outbreak] and phase-II [during the outbreak]. Transitioning back to the normal conditions would most likely depend on the extent and the time duration of this pandemic and associated behavioural change, which is foreseen to remain in effect well beyond the original estimates.
