AbstractStudy Objective. To compare the clinical outcomes of patients with severe postpartum hemorrhage (PPH) managed with and without the use of Point-of-Care Viscoelastic Testing (PCVT) to direct blood product replacement. Design. A retrospective cohort study of consecutive cases of severe PPH managed at a single tertiary care center between January 1, 2011 and July 31, 2015. Cases included patients managed using PCVT. Controls were patients managed using a standardized massive hemorrhage transfusion protocol, either because PCVT was not yet available or because no PCVT credentialed providers were on site. Setting. Delivery room, postoperative recovery area, intensive care unit. Patients. There were 6,708 cesarean deliveries and 13,641 vaginal births during the study period. Eighty six patients (0.4% of all deliveries) developed severe PPH. Severe PPH occurred in 1% (68/6,708) of cesarean and 0.1% (18/13,641) of vaginal deliveries. Twenty-eight of these 86 patients (32.6%) were managed with PCVT and 58 (67.4%) without PCVT. Interventions. Patients with severe PPH were managed according to a standardized massive transfusion protocol or a PCVT-based protocol to direct blood product replacement. Measurements. PCVT testing was performed using a ROTEM delta device. Results. Patients in the PCVT cohort received significantly fewer transfusions of packed red blood cells, fresh frozen plasma, and platelet concentrates. They also had a significantly lower estimated blood loss, and a significantly lower incidence of cesarean hysterectomy and postoperative ICU admission as compared with patients not managed using PCVT. The length of postpartum hospitalization was also significantly shorter in the PCVT cohort. Among patients who gave birth within 24 hours of admission, the direct cost of hospitalization was 40% lower for patients in the PCVT cohort. Conclusions. PCVT-based goal-directed blood product replacement management was associated with substantial benefits over a standardized massive transfusion protocol both in terms of patient outcomes and cost of care.
