ABSTRACT
BACKGROUND: Despite increasing interest in the use of fibrinogen concentrates, cryoprecipitate remains the major source of fibrinogen in England. OBJECTIVES: Understand patterns and indications for use of cryoprecipitate in hospitals from three English regions. METHOD/MATERIALS: Data collection over 3 months from adults, children and neonates receiving cryoprecipitate, including clinical scenario, indications, dose and levels of fibrinogen concentrations pre- and post-transfusion. RESULTS: Four hundred and twenty-three episodes of cryoprecipitate transfusion were analysed from 39 hospitals. Use varied from 0.1 to 4.9 units per 100 red cells transfused. The primary indication was haemorrhage [311 episodes (74%)]. The commonest clinical scenario in all age groups was cardiac surgery, followed by trauma in adults and critical/neonatal care for children. Pre-treatment fibrinogen levels were measured in 322 episodes. In 179 episodes, the level was ≥ 1.0 g L(-1) . CONCLUSION: Wide variation in practice and dose suggests inconsistent practice and uncertainty in the evidence informing optimal use of cryoprecipitate.
