Background Venous thrombosis is common in the older population. Assessment of risk
factors is necessary to implement preventive measures. Objectives We studied the …

Prolonged immobilization and advanced age are considered to be important risk factors for
venous thromboembolism (VTE). Nevertheless, the need for VTE prophylaxis in long-term …

Objectives To determine the role of age‐specific risk factors for thrombosis in older age,
such as functional impairment. Design Case‐control study. Setting The Age and Thrombosis …

Abstract Approximately 50–75% of patients with venous thromboembolism have a readily
identifiable risk factor, either transient or permanent, whereas the remaining episodes are …

BACKGROUND: The thrombogenic burden of immobilization remains unknown especially in
the medical setting. Most of epidemiological studies estimating the link between risk factors …

Background: The risk of venous thrombosis associated with major illnesses is not well
known, and neither is the risk associated with the combined effect of immobilization and …

STUDY OBJECTIVE: Immobility predisposes to venous thromboembolism, but this risk may
vary, depending on the underlying cause of immobility. METHODS: This was a prospective …

BACKGROUND: Hospitalized patients and residents of long-term care (LTC) facilities
account for about 60% of all cases of venous thromboembolism (VTE), as incidence is …

Background Previous studies have reported that around 50% of patients with venous
thromboembolism (VTE) has undergone recent hospitalization. However, studies on the …

While the overall incidence of venous thrombosis is 1–2 per 1000 per year, it is close to 1%
per year in the very old. The case–fatality rate of thrombosis is high in the elderly, particularly …
