269What Happens to Our Oldest Old? A Review One Year Following Acute Hospital Discharge

Background: The number of centenarians is increasing by about 5% annually in many developed countries. Given Ireland’s ageing population, a similar trend in numbers of nonagenarians and centenarians is likely to be found here. Little is known about the health care requirements of this population in Ireland but it is likely that they will contribute significantly to health care use in the future. We aimed to assess the current admission rate and outcome of the oldest old admitted to an acute Level Four hospital. Methods: Our department’s Electronic Patient Record System (ePMS) was searched for all patients aged 90 or above admitted under Care of the Elderly during a 6 month period. Length of stay (LOS), in-hospital mortality, one year readmission and mortality rates were reviewed using ePMS, the hospital’s Integrated Patient Management System (iPMS) and obituary notices. Results: 94 patients were identified. 81.9% were admitted from home. The median LOS was 5 days (min=<1, max = 32, IQR = 10). 20 patients were transferred to a Level Two hospital and the median combined LOS was 7 days (min=<1, max = 47, IQR = 10). The in-hospital and one year mortality rates were 10.63% and 38.1%. The median time from discharge to death was 92 days (min=<1, max = 361, IQR = 151). 45% of patients were readmitted within one year. The median time from discharge to first readmission was 72 days (min = 2, max = 329, IQR = 129). Conclusions: Our population aged 90 years and over have high in-hospital and one year mortality rates. Median length of stay is similar to that found for the over 85 age group in the Activity in Acute Public Hospitals in Ireland Annual Report 2015 and is higher than that of younger populations. Future health care planning needs to take these age related changes into consideration.
