Impact of intrinsic capacity on predicting future falls and readmission in older patients / 中华老年医学杂志

ABSTRACT

Objective:To investigate the prevalence of the decline of intrinsic capacity(IC)and to explore the effect of intrinsic capacity decline on falls and hospital readmission during 1 year follow-up.Methods:A total of 311 elderly patients treated in Geriatrics Department of Zhejiang Hospital were enrolled.General information and intrinsic ability data, including cognitive(simple mental state inventory), motor(Tinetti-Balance Scale and 4 m test), vitality(grip strength and mini-nutrition assessment table), perception(self-rated vision or hearing impairment), and psychosocial(Geriatric depression scale), were collected at admission.Falls and hospital readmission within 1 year after discharge were followed up.Multivariate Logistic regression analysis was used to investigate the relationship of baseline intrinsic ability at admission with falls and hospital readmission during 1-year follow-up.Results:Of 311 elderly hospitalized patients, 282(90.7%)had intrinsic capacity decline.During 1 year follow-up, 38 elderly patients(12.2%)had falls and 69 elderly patients(22.2%)were hospital readmitted.After adjusting for confounding factors such as age, gender, education level, comorbidities, multiple medications, fear of falling, and assistive tool use and so on, Logistic regression analysis showed that decreased balance ability was a risk factor for falls within 1 year in elderly patients( OR=3.515, 95% CI 1.089-11.346, P=0.036), and slow walking speed was a risk factor for one-year hospital readmission( OR=2.426, 95% CI 1.181-4.983, P=0.016). Conclusions:Decreased motor capacity is closely associated with falls and hospital readmission within 1 year in older patients.Great attention should be paid to the assessment and intervention of motor ability in elderly patients.
