Prevalence of platelet dysfunction and abnormal coagulation: results of a population-based study.

The prevalence of impairments in the hemostatic process is unknown in acutely ill people. Data on hemostasis (PFA 100) and the coagulation cascade of 1015 people are presented here, establishing a cohort of unselected emergency patients in a population-based approach. A high prevalence of reduced platelet function (38%) was found, which was more frequent than expected.
