Survival analysis of very elderly inpatients with intertrochanteric fracture / 中华老年医学杂志

ABSTRACT

Objective To study the survival status of very elderly patients with intertrochanteric fracture admitted in hospital and its risk factors.Methods Clinical data of 54 patients with intertrochanteric fracture aged 90 years and over admitted in hospital from Jan.2006 to Dec.2013 were retrospectively analyzed.5 patients were lost to follow-up.The survival status of patients was analyzed.Results Patients were followed up until January 2015.The period of follow-up ranged from 85 months to 0.2 months,with an average follow-up of 33.3 months.17 cases were survived.Harris scores were(61.2 ± 10.6).The overall 1-,3-,5-year survival rates were(0.88 ± 0.05),(0.35 ±0.08),(0.18 ± 0.08),respectively.The mean and median survival times were (33.3 ± 4.6) months and(25.0±5.4) months.Cox proportional hazard regression model showed that American Society of Anaesthesiologists(ASA) score,operation time and the number of comorbidities were the risk factors for the survival time of very elderly patients with intertrochanteric fracture (all P ＜0.05).Conclusions Compared with conservative treatment,surgical treatment can increase the survival time of the elderly patients with intertrochanteric fracture.ASA score,operation time and the number of comorbidities may be the risk factors for the survival time of very elderly patients with intertrochanteric fracture.
