On Friday 30 September at 11:00, Thomas Johannesson Hjelholt defends his PhD dissertation entitled "Associations of Hip Fracture and Stroke in Older Adults - Occurrence, risk, and prognosis".

Proximal femur fracture and acute stroke are common conditions among older persons. Both have an unfavorable prognosis due to high mortality, reduced mobility, and increased dependence.In this thesis, we investigated risk factors for postfracture stroke and developed a prediction model for postfracture mortality. We also examined the impact of a prefracture stroke history on the prognosis following hip fracture in terms of mortality and recurrent fracture. All studies are population-based cohort studies based on the Danish Multidisciplinary Hip Fracture Registry. We found a high risk of postoperative stroke in patients with hip fracture, and the cardivasular risk profile evaluated with the CHA2DS2-VASc score was a useful tool to evaluate the magnitude of the ischemic stroke risk. We developed a novel prediction model to estimate 1-year mortality risk in patients with hip fracture, visualized as an intuitive risk chart. Finally, we establish that prefracture stroke history is an independent risk factor for mortality, whereas the risk of recurrent fracture is modified by patient mobility.

The summary is written by the PhD student.

The defence is public and takes place at Department of Clinical Epidemiology, Oluf Palmes Alle 43-45, 8200 Aarhus N. Please read the attached press release for more information.
