“PLHER" (Platelet / Hematocrit Ratio): A tool to discriminate adult patients assisted at emergency room with or without acute bleeding.
Journal Title: Revista Cuarzo - Year 2019, Vol 25, Issue 2
Abstract
Aim:The diagnosis of acute bleeding (AB), manifested with non-specific, using hematocrit, as a support laboratory is a challenge in the Emergency Room (ER). Ratio platelet / hematocrit (PLHER) operational capabilities to discriminate patients with AB were compared.Methods: With a diagnostic accuracy design, patients with and without AB treated in the ER of Clínica del Occidente S.A. were compared, during 2017. The disease spectrum (EDx) included negative controls [group_0], general public with or without closed orthopedic injuries [groups_1-2], patients with closed orthopedic injuries [group_3], with gynecological AB [group_4], gastrointestinal [group_5] and positive controls [groups_6-7]. It was compared the operational capabilities of PLHER and hematocrit to discriminate patients with AB.Results: 655 patients were selected, mainly men. None differences were observed between hematocrit medians of group_0 and groups_1-2. Compared to group_0, the median PLHER was higher in all EDx groups (p:<0.05). The AUC of the PLHER, to discriminate patients with possible AB [groups 1-3] or any group of the EDx were 0.709 and 0.766, respectively, considering the cut-off points ≥6.037 and ≥6.348. The AUC of the hematocrit to discriminate patients with possible AB or any group of EDx were 0.682 and 0.755, respectively.Discussion: The PLHER showed better operational capabilities than hematocrit to discriminate patients with AB. It could be a useful tool to identify patients with AB treated with non-specific signs and symptoms in ER
