Frailty in anesthesia

Current Opinion in Anaesthesiology
Purpose of review Due to demographic change, the number of geriatric patients is increasing in the surgical field. This poses a major challenge in perioperative medicine. In order to improve patient safety, frailty has become a key element for risk assessment in the perioperative setting.

Parametric frailty and shared frailty survival models [PDF]

Frailty models are the survival data analog to regression models, which account for heterogeneity and random effects. A frailty is a latent multiplicative effect on the hazard function and is assumed to have unit mean and variance theta, which is ...

ICFSR Task Force Perspective on Biomarkers for Sarcopenia and Frailty [PDF]

, 2020
Biomarkers of frailty and sarcopenia are essential to advance the understanding of these conditions of aging and develop new diagnostic tools and effective treatments. The International Conference on Frailty and Sarcopenia Research (ICFSR) Task Force - a

Frailty in survival analysis models (parametric frailty, parametric shared frailty, and frailty in Cox models [PDF]

Frailty models are used to model survival times in the presence of overdispersion or group-specific random effects. The latter are distinguished from the former by the term "shared" frailty models.

Barriers and facilitators to prehabilitation participation among older adults undergoing major elective surgery: a qualitative study using the capability, opportunity, motivation - behavior model

BMC Geriatrics
Background Prehabilitation may improve patients’ functional capacity before surgery and enhance postoperative recovery. This study aimed to identify facilitators and barriers to participation in a multi-component prehabilitation program among older ...

Goodness-of-fit tests for the frailty distribution in proportional hazards models with shared frailty. [PDF]

Frailty models account for the clustering present in grouped event time data. A proportional hazards model with shared frailties expresses the hazard for each subject. Often a one-parameter gamma distribution is assumed for the frailties. The choice of a

Transdisciplinary Research In Frailty: Knowledge Translation To Inform New Models of Care

, 2017
Transforming care for frail older adults requires more than rigorous research. While preventing, identifying and managing frailty are critical to reducing the personal and health systems impact of frailty worldwide, collaborative approaches to research ...

Physical activity trajectories, mortality, hospitalization, and disability in the Toledo Study of Healthy Aging

Journal of Cachexia, Sarcopenia and Muscle, 2020
Background Physical activity (PA) is a recognized contributor to healthy aging. However, the majority of studies exploring its associations with adverse outcomes in cohorts of older adults use single‐time PA estimates, which do not consider its dynamic ...
