This study evaluated blood ordering for acute upper gastrointestinal bleeding. Implementing new guidelines could reduce crossmatched blood by one-third, improving efficiency.

Area of Science:

  • Medicine
  • Clinical Practice
  • Hematology

Background:

  • Acute upper gastrointestinal bleeding is a common emergency.
  • Blood transfusion practices require careful management to ensure patient safety and resource optimization.

Purpose of the Study:

  • To assess blood ordering practices in patients with acute upper gastrointestinal bleeding.
  • To develop evidence-based guidelines for blood ordering in this clinical scenario.

Main Methods:

  • Retrospective analysis of 162 patients with haematemesis admitted via the Accident and Emergency Centre.
  • Classification of patients based on estimated blood loss and hemoglobin levels.
  • Determination of blood units ordered and transfused within 24 hours.

Main Results:

  • The overall crossmatch:transfusion (CT) ratio was 2.4, with variations among medical officers.
  • One patient group exhibited a high CT ratio of 14.9.
  • Lack of clear guidelines contributed to inconsistent ordering patterns.

Conclusions:

  • Developing and implementing clear guidelines for blood ordering in acute upper gastrointestinal bleeding can optimize transfusion practices.
  • Adherence to proposed guidelines could reduce crossmatched blood by approximately one-third.
  • The projected CT ratio with guidelines would be 1.6, indicating improved blood utilization.
