BackgroundPediatric patients requesting bloodless care represent a challenging clinical situation, as parents cannot legally refuse lifesaving or optimal interventions for their children. Here, we report clinical outcomes for the largest series of pediatric inpatients requesting bloodless care and also discuss the ethical considerations.MethodsWe performed a single-institution retrospective cohort study assessing 196 pediatric inpatients (<18 years of age) who requested bloodless care between June 2012 and June 2016. Patient characteristics, transfusion rates, and clinical outcomes were compared between pediatric patients receiving bloodless care and those receiving standard care (including transfusions if considered necessary by the clinical team) (n = 37,271). Families were informed that all available measures would be undertaken to avoid blood transfusions, although we were legally obligated to transfuse blood if the child's life was threatened. The primary outcome was composite morbidity or mortality. Secondary outcomes included percentage of patients transfused, individual morbid events, length of stay, total hospital charges, and total costs. Subgroup analyses were performed after stratification into medical and surgical patients.ResultsOf the 196 pediatric patients that requested bloodless care, 6.1% (n = 12) received an allogeneic blood component, compared to 9.1% (n = 3392) for standard care patients ( P = .14). The most common indications for transfusion were perioperative bleeding and anemia of prematurity. None of the transfusions were administered under a court order. Overall, pediatric patients receiving bloodless care exhibited lower rates of composite morbidity compared to patients receiving standard care (2.6% vs 6.2%; P = .035). There were no deaths in the bloodless cohort. Individual morbid events, length of stay, and total hospital charges/costs were not significantly different between the 2 groups. After multivariable analysis, bloodless care was not associated with a significant difference in composite morbidity or mortality (odds ratio [OR], 0.37; 95% confidence interval [CI], 0.12-1.11; P = .077).ConclusionsPediatric patients receiving bloodless care exhibited similar clinical outcomes compared to patients receiving standard care, although larger studies with adequate power are needed to confirm this finding. There were no mortalities among the pediatric bloodless cohort. Although a subset of our pediatric bloodless patients received an allogeneic transfusion, no patients required a court order. When delivered in a collaborative and patient-centered manner, blood transfusions can be safely limited among pediatric patients.Copyright © 2023 International Anesthesia Research Society.
