Four Patterns in End-of-Life Decline?
International cohort study found physical function declined most rapidly before mortality, while socioeconomic status was associated with more favorable multidomain trajectories.
This study analyzed longitudinal data from 79,305 adults aged 45 and older across 17 countries, revealing that decedents experienced steeper declines in physical, cognitive, and psychological functioning compared to survivors. Four distinct patterns of decline were identified among decedents, with socioeconomic status influencing the likelihood of experiencing unfavorable trajectories.
Background
Understanding the patterns of decline in functioning during the final decade of life is crucial. The study highlights the influence of socioeconomic factors on health trajectories at the end of life.
Data Highlights
Pattern of Decline
Percentage
High functioning with mild declines
44%
Preserved physical and psychological functioning, lower cognitive functioning
31%
Declining physical functioning with worsening cognitive and psychological functioning
14%
Rapidly declining physical functioning with low cognitive and psychological functioning
11%
Key Findings
Decedents showed faster declines in physical, cognitive, and psychological functioning compared to survivors.
Physical functioning declined more rapidly than cognitive or psychological functioning.
Higher socioeconomic status was associated with lower odds of experiencing rapid decline across multiple domains.
Educational attainment had a stronger association with favorable trajectories than household income.
Differences in functioning were more pronounced among specific demographic groups, including females and older participants.
Clinical Implications
Healthcare providers should consider early screening for functional impairments in older adults to identify those at risk of accelerated decline. Understanding co-decline patterns can aid in developing targeted strategies for socioeconomically disadvantaged groups to promote healthier aging.
Conclusion
The study identifies concurrent decline in physical, cognitive, and psychological functioning during the final decade of life, with socioeconomic factors influencing these trajectories.
In a randomized crossover trial of insulin-treated patients receiving hemodialysis, real-time continuous glucose monitoring did not improve the primary hypoglycemia outcome but increased time in range and reduced time above range vs capillary testing.
Nearly 90% of patients who met algorithmic criteria for postacute sequelae of SARS-CoV-2 infection had at least 1 chronic or potentially chronic condition requiring ongoing clinical management.
