title: Need for tailored strategies to diagnose venous thrombo-embolism in older primary care patients. Extension of a keynote presentation at the 2012 Wonca Europe conference.
abstract: Venous thrombo-embolism (VTE, pulmonary embolism and deep vein thrombosis) is common in the elderly and short-term mortality risk increases with age. Hence, notably in older patients, accurately diagnosing VTE can be lifesaving. However, most clinically suspected individuals turn out to have no VTE after imaging examination. Therefore, many physicians would feel reluctant to refer older patients as this can be very burdensome for these patients. Consequently, it is possible that elderly patients are often not referred for diagnostic work-up (risk of under diagnosis), or that treatment for VTE is initiated without confirmation by further testing (risk of overtreatment). Moreover, anticoagulation treatment of VTE is associated with a higher bleeding risk in the elderly. This bleeding risk might even outweigh the potential benefits in some of these patients. Therefore, availability of an accurate diagnostic strategy to safely exclude, and timely diagnose VTE without the need of burdening referrals in many patients might better serve the needs of older patients. Such strategies have been derived and validated in both primary and secondary care patients suspected of VTE. However, the generalizability of these strategies to older patients may be hampered, and their accuracy has never been tested in elderly populations; this in spite of the high prevalence of VTE and the potential for misdiagnosis and thus mistreatment in these patients. Therefore, we advocate validation and adaptation of current diagnostic strategies for VTE for application in elderly patients.
