Muscle Strength and Muscle Mass in Older Patients during Hospitalization: The EMPOWER Study

Abstract: Background: Low muscle strength and muscle mass are associated with an increased length of hospital stay and higher mortality rate in inpatients. To what extent hospitalization affects muscle strength and muscle mass is unclear. Objective: We aimed to assess muscle strength and muscle mass at admission and during hospitalization in older patients and its relation with being at risk of geriatric conditions. Methods: The EMPOWER study included patients aged 70 years and older, admitted to 4 wards of the VU Unive… Show more

“…Accumulation of geriatric deconditioning would reflect progression of sarcopenia. A prospective study including older adult inpatients reported that the cumulative number of unfavorable geriatric conditions, such as risk of fall, delirium, malnutrition, and dependency, was negatively correlated to the amount of muscle mass and degree of muscle strength [25]. The results of our current study might signify a similar conclusion that patients with deconditioning accumulation had greater sarcopenia progression than those without accumulation, even in patients with sarcopenia.…”

“…A systematic review reported that acute admission, but not elective admission, did not decrease muscle mass and strength [14]. Additionally, Van Ancum et al reported that, in a study involving approximately 85% acute admission cases, muscle strength increased during hospitalization [25]. An acute condition may result in the underestimation of muscle strength due to acute symptoms such as fatigue, decreased temperature, pain, and so on.…”

“…The question whether hospitalization by itself is a risk factor for ALD decline is difficult to answer without comparison to trajectories of ADL decline in similar but not hospitalized subjects. In a previous study, muscle measures were not found to change during hospitalization ( 47 ) although immobilization during hospital stay was found to have acute negative impact on muscle mass and strength ( 48 ), which might be further substantiated after discharge.…”

“…The Evaluation of Muscle parameters in a Prospective cohort of Older patients at clinical Wards Exploring Relations with bed rest and malnutrition (EMPOWER) study was a prospective, inception cohort study conducted from April until December 2015 at the VU university medical center in Amsterdam, the Netherlands. An extended description of the protocol is published elsewhere [ 22 ]. In short, patients aged 70 years and older, either electively or acutely admitted to the internal medicine, acute admission, trauma or orthopaedic ward, and who were hospitalized for > 24 h were included in the study.…”
