FALLS DO NOT INCREASE RISK OF MAJOR BLEEDS
An increased risk of falling is often cited asa reason for not using anticoagulation in frailor elderly patients. A recent review of theevidence related to falls and major bleedingepisodes in anticoagulated patients foundthat, in the average patient taking warfarinfor atrial fibrillation (AF), the risk of intracranialhemorrhage from a fall is much smallerthan the risk of a stroke related to AF.
The largest study reviewed 2633 falls in1861 hospitalized patients. The rate ofmajor hemorrhage was 6.2% for patientson warfarin and 11.3% for control patients.As expected, bleeding was more commonin patients with an elevated internationalnormalized ratio. The authors concludedthat withholding anticoagulation shouldnot be made based solely on the patient'srisk of falling.
