Abstract Number: PB0270
Meeting: ISTH 2020 Congress
Theme: Coagulation and Natural Anticoagulants » Critical Care and Perioperative
Background: the concept of identifying laboratory values requiring both immediate laboratory and clinician intervention was originally proposed by George Lundberg, in 1972. The identification and effective communication of so-called “critical values” are vital to good laboratory practice.
Aims: for the purpose of this work, we identified as “critical value” a test result that is clinically significantly outside the normal range, and may represent serious morbidity of life-threatening values.
Methods: A systematic review of the literature was performed to identify papers that reported critical risk result alert thresholds for clinical hemostasis; and compare the date with those obtained in our laboratory for two consecutive years.
Results: the results taken account correspond to the total % of patients who attended the hemostasis sector.
RIN | >5 |
Prothrombin Time | <12% |
APTT | >80 seg |
D-Dimer | > 1 mg/ml |
Anti-XA | > 1.2 U/dl |
[Critical values taken into account]
Year | Data reported |
2018 | 1.2% |
2019 | 1.5% |
[Total data reported per year]
Conclusions: The available data for critical values were as follows: 1.5% for INRs anticoagulated patients; 1.5% for APTT test for anticoagulanted patients; 1.5% for LMWH anti-Xa heparin levels; 1.5 % for D-Dimer (patients with thromboembolism risk). We found our data are according international consensus. Also we recognize that the reporting of critical values for commonly performed coagulation tests generates a significant workload, but it is vitally achieve communication in a timely manner.
