Correlation between frailty and length of hospital stay in elderly acute care patients
Objective To explore the relationship between the changes of frailty and the length of hospital stay in elderly emergency patients.Methods We selected elderly patients admitted to the Second Medical Center of Chinese PLA General Hospital from 2019 to 2022 due to acute diseases.Then we used the InterRAI Acute Care for Comprehensive Geriatric Assessment(AC-CGA)to collect the patient's data,and assessed within 3 days after admission(initial assessment),7 days(reassessment)and 28 days(the length of hospital stay<28 days were assessed on the day before discharge)(final assessment).The frailty index(FI)was extracted from 53 items of the InterRAI AC-CGA,and the FI-AC-CGA model was established to evaluate the frailty status of patients.Logistic regression was used to analyze the relationship between frailty and length of hospital stay.Results Of the 112 patients enrolled,103 were males,with an age range of 60-101 years.At the initial evaluation,29 patients were robust,27 patients were mild frailty,32 patients were moderate frailty,and 24 patients were severe frailty.Compared with the initial evaluation,the number of robust people increased during the re-evaluation and final evaluation,and the number of people with moderate frailty and severe frailty decreased.Multivariate regression analysis showed that frailty was a risk factor for prolonged hospital stay(OR = 5.987,95%CI = 1.101～32.553,P=0.038).The length of hospital stay in the frailty deterioration group was longer than that in the frailty improvement group,Z=-3.284,P=0.001).Conclusion The frailty status and its dynamic changes in elderly emergency patients assessed based on the FI-AC-CGA model are correlated with the length of hospital stay,and patients with worsening frailty have longer hospital stay.
