Why the study?
Does a standardized bleeding history questionnaire accurately indicate hemostatic disorders in general surgical patients?
Does a standardized bleeding history questionnaire accurately indicate hemostatic disorders in general surgical patients?
Preoperative bleeding history is important but can have false-negative results, suggesting it should guide the selection of laboratory tests to identify hemostatic abnormalities.
Bleeding history symptoms may not align with laboratory findings; leaves open the accuracy of standardized questionnaires for hemostatic screening in surgical patients.
Eighty-three general surgical patients completed the standardized bleeding history questionnaire, and screening tests of platelet counts, prothrombin times, partial thromboplastin times, and Ivy bleeding times were done on these patients. Fifty-two per cent had undergone previous operation; 25% described symptoms of potential hemostatic disorders and seven per cent had positive family histories. Laboratory results indicated abnormalities in five patients (6%). The bleeding history is an important part of the preoperative evaluation of a patient, but it can have serious false-negative results. This history should guide the selection of laboratory tests. Such testing can yield an unexpectedly high rate of abnormalities. When identified, these abnormalities require further investigation.
