4CPS-362 Nonagenarians versus non-nonagenarians in the hip fracture patient: from a pharmacotherapeutic point of view

Background and importancePopulation aging is associated with a major hospitalisation rate in nonagenarians; therefore, it is necessary to describe them and analyse any peculiarities.Aim and objectivesTo describe the pharmacotherapeutic profile of nonagenarians versus non-nonagenarians in a cohort of hip fracture patients.Material and methodsIn a retrospective cohort, all hip fracture patients hospitalised in a third level hospital between 9 January 2020 and 5 March 2020 were included. Numerous variables were collected, related to hip fracture (type of fracture and surgery date), biodemography (age, sex, origin and destination on discharge), medical history (dementia, Charlson index and hospitalisation stay), clinical analyses (urea, creatinine and glomerular filtrate) and medication (polypharmacy, anticholinergic burden (according to Duran and Cols equation) and drugs potentially involved with fractures). Continuous variables were expressed as medians (interquartile range) or as means (SD). A descriptive study and a hypothesis contrast test were conducted between nonagenarians and non-nonagenarians. Stata IC14 was used.Results99 patients were included of whom 73 were women and 36.4% were nonagenarians. Mean age in the nonagenarians and non-nonagenarians was 93±2.73 and 86.2±6.83 years, respectively. Hospitalisation stay was similar in both groups (13 days (9–6) in
