Summary
It was the aim of this review to assess the incidence of venous thromboembolism (VTE)
and current practice patterns for VTE prophylaxis among medical patients with acute
illness in Europe. A literature search was conducted on the epidemiology and prophylaxis
practices of VTE prevention among adult patients treated in-hospital for major medical
conditions. A total of 21 studies with European information published between 1999
and April 2010 were retrieved. Among patients hospitalised for an acute medical illness,
the incidence of VTE varied between 3.65% (symptomatic only over 10.9 days) and 14.9%
(asymptomatic and symptomatic over 14 days). While clinical guidelines recommend pharmacologic
VTE prophylaxis for patients admitted to hospital with an acute medical illness who
are bedridden, clear identification of specific risk groups who would benefit from
VTE prophylaxis is lacking. In the majority of studies retrieved, prophylaxis was
under-used among medical inpatients; 21% to 62% of all patients admitted to the hospital
for acute medical illnesses did not receive VTE prophylaxis. Furthermore, among patients
who did receive prophylaxis, a considerable proportion received medication that was
not in accord with guidelines due to short duration, suboptimal dose, or inappropriate
type of prophylaxis. In most cases, the duration of VTE prophylaxis did not exceed
hospital stay, the mean duration of which varied between 5 and 11 days. In conclusion,
despite demonstrated efficacy and established guidelines supporting VTE prophylaxis,
utilisation rates and treatment duration remain suboptimal, leaving medical patients
at continued risk for VTE. Improved guideline adherence and effective care delivery
among the medically ill are stressed.
