Approaches to assessing and minimizing blood wastage in the hospital and blood supply chain

Reducing blood product wastage through the inter-hospital redistribution of near-outdate inventory

BACKGROUND

Hospital transfusion services order blood products to satisfy orders and maintain inventory levels during unexpected periods of increased blood demand. Surplus inventory may outdate before being allocated to a recipient. Blood product outdating is the largest contributor to blood wastage.

STUDY DESIGN

A province-wide redistribution program was designed and implemented to redistribute near-outdate plasma protein and related blood products from low-usage to high-usage hospitals. Program operations and details are described in this paper. Two transport container configurations were designed and validated for transport of all blood products. A cost-analysis was performed to determine the effectiveness of this redistribution program.

RESULTS

A total of 130 hospital transfusion services contributed at least one near-outdate blood product for redistribution between January 2012 and March 2020. These services redistributed 15,499 products through 3412 shipments, preventing the outdating of $17,570,700 CAD worth of product. Program costs were $14,900 for shipping and $30,000 for staffing. Failed time limits or non-compliance with packing configurations resulted in $388,200 worth of blood products (97 shipments containing 816 products) being discarded. Courier transport delays was the most common reason (42/97; 43%) for transport failure.

CONCLUSION

Redistributing near-outdate blood products between hospitals is a feasible solution to minimize outdating. Despite heterogeneity of Canadian blood product inventory, all products (each with unique storage and transport requirements) were successfully redistributed in one of two validated and simple containers. Total operation costs of this program were small in comparison to the $17.6 million in savings associated with preventing the discard of outdated products.

Opportunities to improve feedback to reduce blood component wastage: Results of a national scheme evaluation

BACKGROUND

Blood components are costly and scarce. The Blood Stocks Management Scheme (BSMS) was established in the United Kingdom (UK) to support hospital transfusion services and national blood services through collection, analysis, and monthly feedback of data on blood component inventory and wastage management. There is a growing evidence base on how best to deliver feedback for quality improvement. We assessed the quality and utility of the monthly BSMS component reports.

METHODS

We assessed the content of BSMS reports issued in March 2023 against established criteria for effective feedback. Two researchers independently rated whether criteria spanning the five domains of goal setting, data collection, feedback content, feedback display and feedback delivery were fully, partially or not met. Disagreements were resolved through discussion. We conducted an online questionnaire survey of recipients of BSMS reports during March 2023 to assess their use of reports and seek suggestions for improvement.

RESULTS

Five out of 20 criteria for effective feedback were fully met. Areas for improvement included placing more emphasis in the feedback on positive change, linking data and summary messages, and including specific suggestions for action. Respondents highlighted the value of benchmarked comparisons with other hospital transfusion services.

CONCLUSION

There is scope for enhancing the effectiveness and utility of BSMS feedback reports and hence reducing wastage of blood components. This methodology for evaluation of feedback could be utilized to improve other areas of transfusion practice.

Blood usage and wastage at an academic teaching hospital before the initial wave of COVID-19 and during and after its quarantine periods

BACKGROUND

Transfusion services aim to maintain sufficient blood inventory to support patients, even with challenges introduced by COVID-19.

OBJECTIVES

To review blood usage and wastage before, during, and after COVID-19 surges, and to evaluate effects on inventory.

METHODS

In a retrospective review, we evaluated the association between time periods corresponding to the initial wave of COVID-19 (pre-COVID-19, quarantine, and postquarantine) and blood usage/wastage. Data were stratified by period, and χ2 testing was used to examine the association between these time periods and blood usage/wastage.

RESULTS

In the period before COVID-19, the transfusion service used more units, and in the period after quarantine, more units went to waste. Across all time periods, the most-used product was RBCs, and the most wasted product was plasma. A statistically significant association existed between usage (χ2 [6/3209 (0.2%)]) = 24.534; P ≤.001; Cramer V = 0.62), wastage (χ2 [6/775 (0.8%)]) = 21.673; P = .001; Cramer V = 0.118), and time period. The postquarantine period displayed the highest wastage costs ($51,032.35), compared with the pre-COVID-19 period ($29,734.45).

CONCLUSION

Changes in blood inventory use and waste are significantly associated with the onset and continuation of COVID-19.

Current challenges in platelet transfusion

The supply of platelets for transfusion is a logistical challenge due to the physiology of platelets and current measures of transfusion performance dictating storage at 22°C and a short product shelf-life (<7 days). Demand for platelets has increased in recent years and changes in the demographics of the population may enhance this further. Many studies have been conducted to understand what the optimal dose and trigger for transfusion should be, mainly in hematology patients who are the largest cohort that receive platelets, mostly to prevent bleeding. Emerging data suggests that for bleeding patients, where immediate hemostasis is a key consideration, the current standard product may not be optimal. Alternative platelet preparation methods/storage options that may improve the hemostatic properties of platelets are under active development. In parallel with research into alternative platelet products that might enhance hemostasis, better measures for assessing bleeding risk and platelet efficacy are needed.

Multicenter observational study evaluating the impact of platelet transport bags on product wastage

BACKGROUND

Platelets are the most commonly discarded blood product in Canada, with the most common cause of in-date product loss being improper storage. Transport containers to maintain temperature and extend acceptable return time may represent a method to reduce wastage. The objective of this study was to evaluate the impact of a validated Platelet Transport Bag (PTB) on platelet wastage.

STUDY DESIGN AND METHODS

Thirty-six hospitals with the highest platelet discards were invited to participate in a before-after observational study. Hospitals were instructed to utilize a validated 4-h PTB for clinical situations where immediate transfusion was not planned. Five hospitals audited in-date platelet discards from July 2018 to November 2019 to characterize wastage causes. In-date platelet discard data 12 months before and after the start date for each site were analyzed to determine changes in wastage.

RESULTS

Of 36 hospital sites, 16 agreed to participate. Pre- and postdiscards were 277 and 301, respectively, for all sites combined. There were no significant before-after change in wastage rate (+0.05%, p = .51). Fifty discards were included in the detailed audit; the most common reasons were return to the blood bank after more than 60 min outside a PTB (n = 17, 34%) and return in a red cell cooler (n = 10, 20%).

CONCLUSION

Implementation of PTB did not improve wastage. Common causes of in-date discards were return after 1 h outside of a PTB and placement in a red cell cooler in error. Further research is required to investigate potential strategies to mitigate in-date platelet wastage.

A review of blood usage and wastage in a tertiary heart center

Background/Objectives: Blood is a vital resource that its utilization is ever increasing throughout the world and blood wastage is a global challenge that needs to be controlled. Most blood resources are used during complications of pregnancy, trauma, severe childhood anemia, gynecology, cancers, surgery, hematology disorders, and chronic diseases. Units that are expired, broken bags, returning the blood unit after 30 min, blood clotted units, etc., which are due to lack of awareness may result in the wastage of blood products. The objective of this study is to analyze the usage and wastage of blood and its products in Mazandaran heart center.Methods: In this retrospective study, the survey was carried out on the data that were obtained from Mazandaran heart center of Sari, Iran during 2012-2017. Data included details of usage and wastage on blood and its product units. MS Excel 2016 and SPSS 16.0 were used in analysis and diagrams.Results: A total of 35,686 blood units were consumed, which included 55.7% packed red blood cells (PRBCs), 33.9% platelets (Plts), 8.9% fresh-frozen-plasma (FFP), and 8.9% cryoprecipitates. Moreover, 823 blood units including 41.4% FFP, 37.2% PRBCs, and 21.4% Plts were wasted mostly because of inappropriate order (70.6%). Cross-match to transfusion ratio was 1.13. The intensive care unit reported the highest level of blood intake by 45.0%. The blood group O+ was the most frequent by 34.8%. In addition, blood wastage has decreased over study period by approximately 10.0%.Conclusion: Our study showed not only the increasing pattern of blood usage but also the dropping pattern of blood wastage due to hemovigilance performance and additional training in our healthcare center. We found that the main reason for the blood wastage in this center is an excessive order of blood units.
