Overview
Institutionalized patients may drive most community VTE; leaves open whether prophylaxis reduces incidence in prospective studies.
Structured PICO
What is the population attributable risk of various risk factors for deep vein thrombosis and pulmonary embolism?
P
Population
625 residents with a definite first lifetime deep vein thrombosis or pulmonary embolism diagnosed during the 15-year period 1976 to 1990 and 625 unaffected residents matched for age and sex (total n=1250)
C
Comparator
Unaffected residents matched for age and sex
O
Outcome
Population attributable risk for deep vein thrombosis and pulmonary embolism associated with venous thromboembolism risk factorshard clinical
Institutionalization and related factors account for over 50% of all VTE cases in the community, highlighting the critical need for prophylaxis in hospitalized medical patients.
