Point-of-Care Testing: A Prospective, Randomized Clinical Trial of Efficacy in Coagulopathic Cardiac Surgery Patients
Open accessAbstract
Introduction: The current investigation aimed to study the efficacy of hemostatic therapy guided either by conventional coagulation analyses or point-of-care (POC) testing in coagulopathic cardiac surgery patients. Methods: Patients undergoing complex cardiac surgery were assessed for eligibility. Those patients in whom diffuse bleeding was diagnosed after heparin reversal or increased blood loss during the first 24 postoperative hours were enrolled and randomized to the conventional or POC group. Thromboelastometry and whole blood impedance aggregometry have been performed in the POC group. The primary outcome variable was the number of transfused units of packed erythrocytes during the first 24 h after inclusion. Secondary outcome variables included postoperative blood loss, use and costs of hemostatic therapy, and clinical outcome parameters. Sample size analysis revealed a sample size of at least 100 patients per group. Results: There were 152 patients who were screened for eligibility and 100 patients were enrolled in the study. After randomization of 50 patients to each group, a planned interim analysis revealed a significant difference in erythrocyte transfusion rate in the conventional compared with the POC group [5 (4;9) versus 3 (2;6) units [median (25 and 75 percentile)], P<0.001]. The study was terminated early. The secondary outcome parameters of fresh frozen plasma and platelet transfusion rates, postoperative mechanical ventilation time, length of intensive care unit stay, composite adverse events rate, costs of hemostatic therapy, and 6-month mortality were lower in the POC group. Conclusions: Hemostatic therapy based on POC testing reduced patient exposure to allogenic blood products and provided significant benefits with respect to clinical outcomes.

The Abstract and Discussion report that algorithm-guided management after routine cardiac surgery reduced transfusions compared with clinician discretion. They also report similar blood loss across groups, so the unqualified claim of superior hemostatic therapy is broader than the demonstrated benefit. (LLM, conf=0.84)

The Transfusion Protocols and Discussion sections say the algorithm used the point-of-care thromboelastograph maximum amplitude to guide therapy. The Abstract reports fewer allogeneic plasma and platelet transfusions and less ICU blood loss; the Discussion also reports fewer mediastinal reexplorations for hemorrhage. These findings support the citing sentence’s cautious claim, although the algorithm used other coagulation tests as well. (LLM, conf=0.91)

The Results report fewer cumulative allogeneic blood units with the ROTEM-guided algorithm (9.0 versus 16.0 units; P = .02).

The clinical criteria used for enrollment (diffuse bleeding from capillary beds or blood loss exceeding 250 ml/h or 50 ml/10 min) identify patients with coagulopathy requiring hemostatic therapy.
“Patients were enrolled in the study after heparin reversal following CPB if at least one of the two inclusion criteria were fulfilled: (1) diffuse bleeding from capillary beds at wound surfaces requiring hemostatic therapy as assessed by the anesthesiologist and surgeon by inspecting the operative field and/or (2) intraoperative or postoperative (during the first 24 postoperative hours) blood loss”
The paper relies on this without support.
The amount of transfused packed erythrocytes is a reliable surrogate parameter for the efficacy of hemostatic therapy.
“Because the amount of transfused packed erythrocytes represents a reliable surrogate parameter for the efficacy of hemostatic therapy, it was defined as the primary outcome variable of the current study.”
The paper relies on this without support.
Bleeding and the consecutive need for transfusion of packed erythrocytes in the intraoperative period and the first 24 h after surgery reflect the surgery-associated coagulopathy and the potential effects of different hemostatic strategies.
“Bleeding and the consecutive need for transfusion of packed erythrocytes in the intraoperative period and the first 24 h after surgery most likely reflect the surgery-associated coagulopathy and thus the potential effects of different hemostatic strategies.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-02, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-02 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
