摘要: Methods: The medical records of residents from the Worcester metropolitan area diagnosed as having Inter- national Classification Diseases, Ninth Revision codes consistentwithpossibleVTEduring1999,2001,and2003 were independently validated and reviewed by trained abstractors. Results: A total 1897 subjects had a confirmed epi- sode VTE. In all, 73.7% patients developed VTE in outpatient setting; substantial proportion these undergone surgery (23.1%) or hospitaliza- tion (36.8%) preceding 3 months. Among patients, 67.0% experienced within 1 month hospital encounter. Other major risk factors for setting included active malig- nantneoplasm(29.0%)orpreviousVTE(19.9%).Among 516 with recent hospitalization who subse- quently VTE, less than half (42.8%) re- ceivedanticoagulantprophylaxisforVTEduringthatvisit. Conclusions:MoreVTEswerediagnosedinthe3months followinghospitalizationthanduringhospitalization.Ef- forts to improve in-hospital use prophylaxis may help decrease incidence How- ever,giventheshorteningofhospitalstays,studiesofex- tendedVTEprophylaxisfollowinghospitaldischargeare warranted.
