Patients Given Traditional Cryo
These are all liver transplant and cardiothoracic (LT and CT) patients that will be given Traditional Cryo based on the randomization protocol. The blood bank will be randomized by to use either PR Cryo or Traditional Cryo for the entire month for all patients with a Cryo order. The patients included in this arm received Traditional Cryo during a month in which the blood bank was randomized to use Traditional Cryo. The months in which the blood bank was assigned to use Traditional Cryo are as follows: Period 1: Month 1, Period 4: Month 4, Period 5: Month 5, Period 7: Month 7, Period 10: Month 10, and Period 12: Month 12.

These are all liver transplant and cardiothoracic (LT and CT) patients that will be given PR Cryo based on the randomization protocol. The blood bank will be randomized by to use either PR Cryo or Traditional Cryo for the entire month for all patients with a Cryo order. The patients included in this arm received PR Cryo during a month in which the blood bank was randomized to use PR Cryo. The months in which the blood bank was assigned to use PR Cryo are as follows: Period 2: Month 2, Period 3: Month 3, Period 6: Month 6, Period 8: Month 8, Period 9: Month 9, Period 11: Month 11.

SECONDARY outcome

Timeframe: Daily, up to approximately 24 months

Population: The blood bank, which is required to follow its standard operating procedures, was not able to document wastage in a way which allowed the investigators to accurately attribute wastage to a specific arm of the study. Therefore, wastage could not be accurately calculated as intended in the study protocol.

This captures the Cryoprecipitate units discarded.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: Variable, but it is generally available within 15 minutes of the start of ROTEM testing.

Population: Data for all participants was not available because pre-transfusion FIBTEMs were not clinically ordered for all participants by the treating anesthesiologists. Only participants with pre-transfusion FIBTEMs available were included in this analysis.

FIBTEM before transfusion, if anesthesiologist orders it. FIBTEM is a point of care laboratory test measuring fibrinogen contribution to a clot. It is part of ROTEM testing and helps providers determine if patients need fibrinogen supplementation during surgical bleeding.

SECONDARY outcome

Timeframe: Variable, but it is generally available within 1 hour of the start of ROTEM testing.

Population: Data for MCF were not collected since clinical decisions are not made based on this value as the measure assumed. As such, there are no data to report. Clinical decisions were made based on A10 (the clot amplitude measured 10 minutes after clot formation start), not the maximum clot firmness (MCF). As A10 was not a pre-specified measure for this protocol, there are no data to report. Data will never be collected for this Outcome Measure.

The maximum strength of a clot as determined by ROTEM testing.

The blood bank will alternate use of PR cryo and regular cryo each month for all patients with a cryo order. All patients will receive either traditional cryo or PR cryo in a given month. Traditional Cryoprecipitate: This is the cryoprecipitate already currently being given to patients with a cryo order.

SECONDARY outcome

Timeframe: Daily, approximately 24 months

Population: Not available due to unavailable confidential contractual information that would be needed to calculate cost. The contract between the blood suppliers and hospital is confidential, and therefore the investigators were not able to report on cost-related factors as intended in the study protocol. Data will never be collected for this Outcome Measure.
