Long-term audit of platelet consumption in a university hospital

Optimising platelet usage during the induction therapy of acute myeloid leukaemia: Impact of physician education

INTRODUCTION

Platelet products are scarce and expensive resources to be used judiciously. However, inappropriate usage is common. Lack of physician awareness is an important issue. We implemented a physician education program (PEP) along with repeated WhatsApp reminders at our centre. We audited the platelet usage practise before and after the intervention.

METHODS

Charts of patients with acute myeloid leukaemia (AML) treated between January 2020 and August 2020 was reviewed, and the mean platelet usage per patient per day was calculated. Physician education was implemented between September 2020 and December 2020 (2 PowerPoint lectures of 20 min each and weekly WhatsApp messages containing the guidelines). Data of patients treated between Jan 2021 and August 2021 was prospectively audited to understand platelet usage and the indications for transfusions. The British Committee for the Standards in Haematology (BCSH) platelet transfusion guidelines were used as the adjudication tool to evaluate compliance. The mean platelet usage per day per kg body weight of a patient before and after the PEP was compared using the t-test.

RESULTS

Group A (before physician education) consisted of 22 patients, and group B (after physician education) consisted of 23 patients. The mean number of platelet transfusions for each patient in a day per kg body weight was 125.7 × 10⁸ in group A whereas, after the PEP, it had reduced to 73.9 × 10⁸ amounting to an absolute reduction of 51 × 10⁸ (58.8%) from the baseline with a statistical significance of P = 0.001. After implementing the PEP, the mean number of random donor platelets used reduced by 10.25 units (34% reduction), and the mean single donor platelets used reduced by 0.83 units (19% reduction). The 190 requests for platelet transfusion received during this period were classified as appropriate (157/190), which constituted 82.63% of the requests, or inappropriate (33/190), which accounted for 17.36%.

CONCLUSIONS

A short-duration education programme supplemented with weekly WhatsApp messages and an active feedback mechanism on the rationale of platelet transfusion by the treating physician and transfusion specialist could significantly reduce platelet consumption during the therapy of acute myeloid leukaemia patients. This is a measure that can be considered by all high-volume haematology centres, which can improve patient safety and reduce costs.

Plasma and Platelet Transfusion Strategies in Critically Ill Children Following Noncardiac Surgery and Critically Ill Children Undergoing Invasive Procedures Outside the Operating Room: From the Transfusion and Anemia EXpertise Initiative-Control/Avoidance of Bleeding

OBJECTIVES

To present consensus statements and supporting literature for plasma and platelet transfusions in critically ill children following noncardiac surgery and critically ill children undergoing invasive procedures outside the operating room from the Transfusion and Anemia EXpertise Initiative - Control/Avoidance of Bleeding.

DESIGN

Systematic review and consensus conference of international, multidisciplinary experts in platelet and plasma transfusion management of critically ill children.

SETTING

Not applicable.

PATIENTS

Critically ill children undergoing invasive procedures outside of the operating room or noncardiac surgery.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

A panel of 10 experts developed evidence-based and, when evidence was insufficient, expert-based statements for plasma and platelet transfusions in critically ill children following noncardiac surgery or undergoing invasive procedures outside of the operating room. These statements were reviewed and ratified by the 29 Transfusion and Anemia EXpertise Initiative-Control/Avoidance of Bleeding experts. A systematic review was conducted using MEDLINE, EMBASE, and Cochrane Library databases, from inception to December 2020. Consensus was obtained using the Research and Development/University of California, Los Angeles Appropriateness Method. Results were summarized using the Grading of Recommendations Assessment, Development, and Evaluation method. We developed eight expert consensus statements focused on the critically ill child following noncardiac surgery and 10 expert consensus statements on the critically ill child undergoing invasive procedures outside the operating room.

CONCLUSIONS

Evidence regarding plasma and platelet transfusion in critically ill children in this area is very limited. The Transfusion and Anemia EXpertise Initiative-Control/Avoidance of Bleeding Consensus Conference developed 18 pediatric specific consensus statements regarding plasma and platelet transfusion management in these critically ill pediatric populations.

The future of voluntary blood donation in the Kingdom of Saudi Arabia

Replacement blood donations are a major source of blood in KSA. This presentation highlights "the peace time and war experiences," where the voluntary donor potential was tested. THE "PEACETIME EXPERIENCE"-KING SAUD UNIVERSITY STUDENT DONOR DRIVE: This donor drive commenced in 1983 with 13 donors in its first and the annual collection reached 4500 blood units in the academic session 1995-1996, when the student enrollment was around 30,000. In 2018 the enrollment jumped to 120,000 students. If we add the staff and auxiliary personnel, the population of potential voluntary blood donors will be enough to cover the current and future blood needs of King Khalid University Hospital. Unfortunately, this drive did not survive due to administrative and organizational difficulties. THE "FIRST" GULF WAR EXPERIENCE: At the end of 1990, when the Allied Forces started to end the Iraqi occupation of Kuwait, the Saudi Ministry of Health waged a publicity campaign asking healthy individuals to donate their blood. The response was phenomenal, and the blood inventory in blood banks swelled about five- to sevenfold. First-time donors broke the "fear barrier," went through the donation experience, and it is hoped they will return to donate voluntarily. CONCLUSIONS: The major lesson learned from the King Saud University student donor drive and Gulf War experience is the enormous voluntary donor potential in Saudi Arabia. There is a need for forward planning to shift the current partial involuntary donor system to a voluntary system based on nonremunerated donors.
