To assess BMI and AHtR outliers, each variable was converted to a normal distribution based on the best Box-Cox transformation.
Binary logistic regression was performed on each cardiometabolic risk outcome (0 = healthy; 1 = unhealthy) as predicted by BMI percentile or AHtR, including a main effect and interaction with sex and race/ethnicity.
Youden's Index, J (sensitivity + specificity - 100), identified the optimum age-invariant cutoff of AHtR separately for males and females (Figure 1), which best classified adolescents as healthy/unhealthy on overall cardiometabolic risk.
Frequency and percentages for individuals aged 12-18 with healthy and unhealthy levels of each cardiometabolic variable within each BMI and AHtR level were cross-tabulated.
Clinical symptoms and recommended nursing management for AHTR are summarized in Table 1.
AHTR may occur immediately or within several hours after a transfusion.
Recently published case studies support the current state of knowledge regarding the clinical appearance of AHTR in hospitalized adults.
Preece, Magrin, Webb, Akers, and Davis (2011) recorded a case of AHTR resulting from transfusion of RBCs to a 67-year-old female with an unrecognized anti-Al antibody.
AHTR can occur where the wrong patient is given the blood.
The combined effect gives rise to the signs and symptoms associated with AHTR, including shock and disseminated intravascular coagulation (DIC).
AHTR can occur at any time throughout, or up to 24 hours following, a transfusion, making on-going monitoring essential.
Actions: If AHTR is suspected, stop the transfusion immediately and maintain intravenous access with normal saline (through a fresh giving set).
