Triggers for venous thromboembolism (VTE) during hospitalization (such as immobility and cancer) are well known, but triggers that cause hospitalization for VTE are less well documented. U.S. investigators used linked clinical and administrative datasets to carry out a case-crossover analysis, in which each person served as his or her own control; risk factors were identified that occurred disproportionately in the 90 days before hospitalization for VTE among nearly 17,000 older people.
The most commonly identified trigger was infection — present in 52% of VTE cases and associated with an adjusted incidence rate ratio (IRR) of 2.90, which rose to 6.92 when infection was associated with a previous hospital or skilled nursing facility stay. Bl…
