Recurrent event data is a special type of multivariate survival data. Dynamic and frailty models are one of the approaches that dealt with this kind of data. A comparison between these two models is studied using the empirical standard deviation of the standardized martingale residual processes as a way of assessing the fit of the two models based on the Aalen additive regression model. Here we...

Average life expectancy is increasing in the western world resulting in a growing number of frail individuals with coronary heart disease, often associated with comorbidities. Decisions to proceed to invasive interventions in elderly frail patients is challenging because they may gain benefit, but are also at risk of procedure-related complications. Current risk scores designed to predict morta...

BACKGROUND The low physical activity domain of the frailty phenotype has been assessed with various self-reported questionnaires, which are prone to possible recall bias and a lack of diagnostic accuracy. The primary purpose of this study was to define the low physical activity domain of the frailty phenotype using accelerometer-based measurement and to evaluate the internal construct validity ...

Background Hospitalization events exact a substantial toll across the age spectrum. Frailty is associated with all-cause hospitalization among HIV-uninfected adults aged 65 years and older. Limited data exist on the frailty relationship to hospitalization among HIV-infected persons or those aged less than 65 years. Comparative investigation of the frailty relationship to specific classes of hos...

OBJECTIVE To discuss models of care for frail seniors provided in primary care settings and those developed by Canadian FPs. SOURCES OF INFORMATION Ovid MEDLINE and the Cochrane database were searched from 2010 to January 2014 using the terms models of care, family medicine, elderly, and geriatrics. MAIN MESSAGE New models of funding for primary care have opened opportunities for ways of ca...

Cardiovascular diseases (CVDs) are the leading cause of morbidity and mortality. With the ageing population, the prognostic determinants among others include frailty, health status, disability, and cognition. These constructs are seldom measured and factored into clinical decision-making or evaluation of the prognosis of these at-risk older adults, especially as it relates to high-risk interven...

Background Understanding and addressing the needs of frail persons is an emerging health priority for Nova Scotia and internationally. Primary healthcare (PHC) providers regularly encounter frail persons in their daily clinical work. However, routine identification and measurement of frailty is not standard practice and, in general, there is a lack of awareness about how to identify and respond...

OBJECTIVES To determine whether physical frailty is associated with low-grade inflammation in older adults with depression, because late-life depression is associated with physical frailty and low-grade inflammation. DESIGN Baseline data of a cohort study. SETTING Primary care and specialized mental health care. PARTICIPANTS Individuals aged 60 and older with depression according to Diagn...

Frailty is a clinical syndrome defined by the age-related depletion of the individual's homeostatic reserves, determining an increased susceptibility to stressors and disproportionate exposure to negative health changes. The physiological systems that are involved in the determination of frailty are mutually interrelated, so that when decline starts in a given system, implications may also rega...
