Baseball legend Leroy “Satchel” Paige famously said that “age is a question of mind over matter: If you don’t mind, it doesn’t matter.”
But even the strongest and most supple minds can’t avoid the effects of advanced age and accompanying physical frailty, and for community-dwelling elderly with pulmonary diseases frailty is a predictor of both hospitalization and death, investigators have found.
For example, among 1,188 community-dwelling older adults enrolled in the Toledo (Spain) Study for Healthy Aging, declining pulmonary function measured by forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) was associated with increased risk for frailty and hospitalization, and a more than twofold greater risk for death in participants both with and without respiratory diseases. These findings were reported by Walter Sepulveda-Loyola, PT, MSC, PhD, from the Faculty of Health and Social Sciences at Universidad de Las Americas in Santiago, Chile, and colleagues in the journal Heart & Lung.
Similarly, results of a meta-analysis performed by investigators at Jiangsu (China) University showed that among 13,203 patients with chronic obstructive pulmonary disease (COPD), frailty was associated with a more than 2.6-fold relative increase in risk for death from any cause, and “prefrailty,” an intermediate state between frailty and “robustness,” was associated with a 48% relative increase in all-cause mortality. Frailty was also associated with a 2.2-fold risk for COPD exacerbations of any severity, the authors reported in JAMDA: The Journal of Post-Acute and Long-Term Care Medicine.
The good (old) USA
In June 2023 the U.S. Census Bureau announced that the median age of the U.S. population is now 38.9 years, and according to a 2016 Census Bureau report funded by the National Institutes of Health, “America’s 65-and-over population is projected to nearly double over the next three decades, from 48 million to 88 million by 2050.”
With the graying of the U.S. population the burden on pulmonary and critical care experts will almost inevitably increase, as evidenced by research from Julien Cobert, MD, from the University of California, San Francisco, and colleagues.
The investigators looked at trends over time in older adults admitted to ICUs from 1988 through 2015 using data from the Health and Retirement Study (HRS), a nationally representative, longitudinal study of older adults. They found that rates of preexisting frailty, disability, and multimorbidity increased over the study period.
“Our findings suggest a growing prevalence of geriatric conditions among older adults admitted to the ICU, suggesting a pressing need to integrate geriatric principles into critical care medicine. Further research could examine if early interventions emphasizing physical, cognitive, mental health, delirium prevention, advance care planning, and rehabilitation individualized to critically ill elderly patients with preexisting geriatric conditions could improve ICU outcomes and post-ICU recovery,” they wrote in a study published in the journal CHEST.
In an editorial accompanying the study by Dr. Cobert and colleagues, Nathan E. Brummel, MD, from The Ohio State University College of Medicine and Davis Heart and Lung Research Institute in Columbus, said “the finding that nearly 30% of overall HRS participants were admitted to the ICU provides novel data about the extent to which older Americans are affected by critical illness. Because the number of older Americans is projected to continue to increase for the next 30 years or more, these data make clear the ongoing importance of aging-focused research and clinical care.”
Dr. Brummel also noted that older adults who are admitted to the ICU today are at greater risk for poor outcomes than those admitted in prior years, as evidenced by the increased prevalence of disability, frailty, and multimorbidity.
“Moreover, because the average age of those admitted to the ICU only changed by 1 year during the study, these data show that increases in vulnerability are not simply due to chronological age, and they suggest that to identify those with greater baseline vulnerability, screening for geriatric syndromes at ICU admission may be warranted,” he wrote.
