BackgroundCritically bleeding trauma patients require coordinated and efficient decision-making processes to ensure optimal management of their massive transfusion (MT) requirements. Human factors (HFs) is a discipline that investigates factors influencing work processes from the organizational, group, and individual levels. Given the complexity of trauma resuscitation, implementing any intervention for decision support in MT is challenging and may benefit from a HFs-assisted approach.Study Design And MethodsA systematic review was performed to identify reports of the introduction of any type of decision support for the provision of MT in critically bleeding adult trauma patients. Crucial contributions reported to influence design and uptake of the intervention were categorized into four HFs categories (environment, human, machine, and task). Extracted information was supplemented by surveying the contact authors. Evidence of clinical practice changes resulting from the intervention was also considered.ResultsWe identified nine studies that had reported an intervention implementing new practice guidelines or a MT protocol. All were before-and-after comparative cohort studies and used historical controls as the preintervention cohort.ConclusionBased on the identified reports, this review provides a HFs-assisted approach to aid clinicians and policy makers with the implementation of decision support for MT in the trauma care setting.© 2012 American Association of Blood Banks.
