OBJECTIVES To determine whether a designation of frailty using the Adjusted Clinical Groups-diagnoses based computerized predictive model (ACG Dx-PM) can identify an elderly population who (1) have the clinical characteristics of frailty and (2) are frail as determined by the validated Vulnerable Elders Survey (VES), and to determine the ability of these tools to predict adverse outcomes. STU...

Objective To investigate the association of frailty syndrome with socioeconomic and health variables among older adults. Methods This is a cross-sectional, observational and analytical household research conducted with a sample of 1,609 urban elderly. We used: semi-structured questionnaire, scales (Katz, Lawton and shortened version of Geriatric Depression Scale) and Fragility Phenotype propo...

BACKGROUND This study validates cut-points for a frailty index (FI) to identify seniors at risk of a hospital-related event and estimates the number of frail seniors living in the community. The FI developed by Rockwood and Mitnitski defines levels of frailty based on scores of 0 to 1.0. DATA AND METHODS The cut-point validation was conducted using Stratum-Specific Likelihood Ratios applied t...

Abstract The Cox proportional hazards model has become the most widely used procedure in survival analysis. theoretical basis of original been developed various extensions. In recent years, vital research undertaken involving incorporation random effects to models. this setting, effect is a variable ( frailty ) which embraces variation among individuals or groups cannot be explained by observab...

OBJECTIVE Despite the recurring nature of the disease process in many psychiatric patients, individual careers and time to readmission rarely have been analysed by statistical models that incorporate sequence and velocity of recurrent hospitalisations. This study aims at comparing four statistical models specifically designed for recurrent event history analysis and evaluating the potential imp...

BACKGROUND The prevalence and significance of frailty are seldom studied in hospitalized patients. Aim of this study is to evaluate the prevalence of frailty and to determine the extent that frailty predicts delirium, falls and mortality in hospitalized older patients. METHODS In a prospective study of 220 older patients, frailty was determined using the Cardiovascular Health Study (CHS) and ...

BACKGROUND Frailty is related to adverse outcomes in the elderly. However, current status and clinical significance of frailty have not been evaluated for the Korean elderly population. We aimed to investigate the usefulness of established frailty criteria for community-dwelling Korean elderly. We also tried to develop and validate a new frailty index based on a multidimensional model. METHOD...

BACKGROUND There are several different frailty measures available for identifying the frail elderly. However, their predictive performance in an Australian population has not been examined. OBJECTIVE To examine the predictive performance of four internationally validated frailty measures in an older Australian population. METHODS A retrospective study in the Australian Longitudinal Study of...
