- Scientific TitleDevelopment of a clinical prediction model for bleeding complications in hospitalized patients using coumarins.
- ACRONYM
- hypothesisBy developing a model which predicts the risk of bleeding with coumarin use, patients can be treated more effectively, potentially avoiding the need for specific antidotes. Besides decreasing the risk of bleeding (potentially resulting in less morbidity and mortality), such a prediction model may also lead to a reduction in healthcare costs.

- Brief summaryReduction of (avoidable) errors is one of the key goals of the patient safety program within Dutch healthcare in general and within the Erasmus MC in specific. This pilot project for identifying patients with a high risk of bleeding complications while using coumarins fits this goal. Using electronic patient data, risk factors for a high risk of bleeding complications will be identified and a clinical prediction model for potential bleeding complications will be developed. This prediction model can be used on hospitalized patients using coumarins. A high INR (international normalized ratio), and/or use of the coumarin antidotes vitamin K and prothrombin complex concentrate (PCC), use of tranexamic acid, blood transfusions and death serve as indicators to identify these patients. The objective is the identification of electronically available risk factors and the development of a clinical prediction model to identify patients at risk for a bleeding complication while using coumarins.
It is a (nested) case control study in hospitalized patients with one or more prescriptions of coumarins, in the four year period 2006-2009. This study will be carried out using (historically) documented electronic patient data. All patient data are coded using non-traceable codes. Patients with an INR > 4.5 are generally regarded as being at high risk for a bleeding complication. Regression analysis will be used for data-analysis, using 'backward selection' to select the strongest predictors for having a high INR in a multivariate regression model.
