Introduction Geriatricians have been increasingly involved in the pre-operative process in frail elderly patients with a hip fracture which can benefit re-hospitalization, post-operative functional performance, and mortality. The objective of this study was to compare the number of older patients with hip fractures who opted for non-surgical management after the addition of pre-operative comprehensive geriatric assessment (CGA) with shared decision making by a geriatrician to usual care. Secondary objectives were: reasons for non-surgical management, duration of life, and location of death. Materials and methods A single-center, with a level 2 trauma center, retrospective study comparing care before and after introducing pre-operative CGA with shared decision making in September 2014. Patients ≥ 70 years with a hip fracture, admitted from January 2014 to September 2015, were included. The percentages of patients elected for non-surgical management and palliative care without or with CGA were compared. Differences in secondary objectives (age, sex, medical history, medication use, functional, and social status) were compared descriptively and qualitatively. Results With pre-operative CGA significantly more patients (or representatives) elected the non-surgical management option after hip fracture (respectively, 9.1% vs 2.7%, p  = 0.008). Patient characteristics were comparable. Reported reasons not to undergo surgery include aversion to be more dependent on others, and severe dementia. Conclusion The geriatrician can have an important role in decisions for non-surgical management by shared decision making in the pre-operative period in patients ≥ 70 years with a hip fracture in the emergency room.
