Heparin-Induced Thrombocytopenia Registry
- Conditions
- Heparin-Induced Thrombocytopenia
- Registration Number
- NCT00456326
- Lead Sponsor
- Brigham and Women's Hospital
- Brief Summary
The purpose of the Heparin Induced Thrombocytopenia Registry is to explore the frequency of heparin-induced thrombocytopenia (HIT) at Brigham and Women's Hospital and to assess its mortality rate. Retrospective 3 years, looking forward prospectively.
- Detailed Description
Heparin-induced thrombocytopenia (HIT) is an immune-mediated adverse drug reaction with potentially fatal complications of venous and arterial thrombosis.
HIT with thrombosis causes prolonged hospital length of stay and is associated with catastrophic outcomes such as extremity amputation as well as death. The fear of HIT has led to some proposals to minimize hospital use of unfractionated heparin (UFH) and low molecular weight heparin (LMWH) and to substitute other anticoagulants that have not been reported to cause HIT. Therefore, the frequency of confirmed HIT and the frequency of determining whether UFH or LMWH is the causative agent urgently require further investigation.
At BWH, we have placed patient safety at a premium. We have a Patient Safety Committee and a Patient Safety Officer. HIT has been identified as one of the primary problems requiring urgent policy decisions. Consequently, we have formed a multi-disciplinary team of physicians, pharmacists, nurses and physician's assistants to improve safe medication practices for patients receiving anticoagulation.
Our primary objectives are to establish an HIT registry which will provide information on:
1. Incidence of HIT associated with UFH and LMWH
2. Outcomes of patients with HIT
3. Adverse events associated with alternative anticoagulants used to treat HIT
We will obtain data with respect to: Drug, Dose, Route of administration, Duration of therapy, Platelet count, Platelet nadir, Co-morbidities (Coronary Artery Disease, Diabetes Mellitus, Myocardial Infarction, Hypertension, Pulmonary Disease, Chronic Renal Failure, Malignancy, Liver Disease, Surgery, Sepsis), Baseline characteristics (Age, Sex, Weight), Pregnancy status, Serum Creatinine, AST, ALT, Hematocrit, Hemoglobin, Venous and Arterial Thrombotic events (DVT, PE, CVC), 30-day mortality rate, alternative anticoagulant therapy, and duration of therapy.
Time and Method of Data Collection:
Chart Review for the duration of hospitalization: Hemorrhagic event, Thrombotic events, and 30-day Mortality Rate.
