Massive blood transfusion during hospitalization for delivery in New York State, 1998-2007.

ABSTRACT:

Objective

To define the frequency, risk factors, and outcomes of massive transfusion in obstetrics.

Methods

The State Inpatient Dataset for New York (1998-2007) was used to identify all delivery hospitalizations for hospitals that reported at least one delivery-related transfusion per year. Multivariable logistic regression analysis was performed to examine the relationship between maternal age, race, and relevant clinical variables and the risk of massive blood transfusion defined as 10 or more units of blood recorded.

Results

Massive blood transfusion complicated 6 of every 10,000 deliveries with cases observed even in the smallest facilities. Risk factors with the strongest independent associations with massive blood transfusion included abnormal placentation (1.6/
