Abstract

Introduction

Centenarians and nonagenarians constitute a rapidly growing age group in Western countries and they are expected to be admitted to hospital with hip fractures. The aim of this study was to compare outcomes of centenarian and nonagenarian patients following a hip fracture and to identify risk factors related to in-hospital and post-discharge mortality in both groups.

Patients and methods

A prospective evaluation of centenarian patients and nonagenarian controls admitted to a tertiary university hospital in Barcelona with hip fractures over a period of 5 years and 9 months. Baseline characteristics and outcomes in both patient groups were compared. Variables associated with in-hospital, 30-day, 3-month and 1-year mortality were also analyzed.

Results

Thirty-three centenarians and 82 nonagenarians were included. The most relevant statistically significant differences found were: Barthel index at admission (61.90 vs. 75.22), number of drugs before admission (4.21vs 5.55), in-hospital complication rates (97 vs. 78%), readmissions at 3 months and 1 year (0 vs 11.7% and 3.4 vs. 19.5% respectively) and mortality at 3 months and 1 year (41.4 vs. 20.8% and 62.1 vs. 29.9%, respectively). Mean number of complications, rapid atrial fibrillation, mean age, and urinary tract infection were risk factors associated with mortality.

Conclusions

Centenarian patients had similar in-hospital outcomes to nonagenarians, but experienced more complications and twice the 3-month and 1-year mortality rate. The mean number of complications was the risk factor most consistently related to in-hospital and post-discharge mortality. These findings emphasize the need to improve care in very old patients to prevent complications.
