Treatment Decisions in Older Adults: improving care in the last years of life.
Theme 1: Improving quality of life of older adults with a fracture, especially vertebral fractures leading towards hyperkyphosis, hip fractures and pelvic fractures.
- Frail hip study, PhD Sverre Loggers (Erasmus MC); Evaluation of non-operative versus operative management of high risk patients with hip fracture. Is non-operative an equivalent option?
- Non operative management in hip fracture - implementation study (PhD Paulieke Oosterwijk)
- PENG study: Is a hip denervation with phenol a good option in non-operative management of hip fracture in oder adults at the end of life? (PhD Thamar Kroes)
- Apollo trial, PhD Mathilde Tol; Is a direct lateral incision in patients with hip fracture more prone for falling than a posterolateral incision?
- Skyfall-study, PhD Marije Koele; Is hyperkyphosis related to falling and reduced physical function?
- Fx Movie study, PhD Merle Schene (MUMC): Patients after their first fracture: who will fall again and sustain another fracture?
- PELVIC trial: stepped wedge RCT improving the care pathway of older adults with a fragility fracture of the pelvis.
Theme 2: Treatment decisions in geriatric care and healthcare evaluation, focus on implementation
- Oscar Smeekes, PhD, Dolce Vita project with Bianca Buurman.: Data driven optimalisation of older adults recieving emergency care: Can modelling improve waiting times?
- Sofie Rutten: TRUST study: (Tijd en ruimte voor sterven en transitie): Data driven models of elective care in the final phase of life. Is there time to realize what is best?
-Sophie van der Heide: Implementation of Advance Care Planning in heartfailure patients
