273 Characteristics of Centenarians in the Irish Hip Fracture Database

Background In 2017 the Central Statistics Office reported that there were 465 people over the age of 100 in Ireland. This number is likely to increase and, as hip fracture increases exponentially with age, we can expect to see more centenarians experiencing hip fracture. In the UK we have comparative data on such a cohort. We sought to define and describe those aged 100 years and over included in the Irish Hip Fracture Database from 2013-2017. Methods A secondary analysis of the 15,603 data entries in the IHFD between 2013 and 2017 was conducted. Those patients aged 100 years and over were identified and the cohort described. Results 57 patients 100 years and over (average 101 range 100-105) were registered in the IHFD over these 5 years. 91% were female. The most common fractures were intertrochanteric (46%) and displaced intracapsular (30%). 55 patients underwent an operative procedure, the most common being bipolar hemiarthroplasty (28%). Over one third were mobilised on the day of or day after surgery. The average length of stay was 22.5 days with only 13 ICU days for the entire cohort. 7 patients died in hospital. Of those surviving to discharge, discharge destination was recorded for 20. 10 patients returned to nursing home, 5 admitted de novo to nursing home, 5 to offsite rehabilitation and one person discharged directly to home. Conclusion This data provides the first insight into hip fractures in the oldest old in an Irish context. Rate of operative intervention was reassuringly high with in-hospital mortality outcomes of 12% which is low by international standards. The age of those sustaining hip fractures is increasing with numbers of the oldest old expected to rise. Orthogeriatric input results in improved care for this population and will require increased resourcing for future cohorts of patients.
