Persistent cognitive decline in older hospitalized patients in Taiwan

Does hospitalisation impact the successful ageing of community-dwelling older adults?: A propensity score matching analysis using the Korean national survey data

OBJECTIVES

For community-dwelling older adults with hospitalisation experience, it is necessary to be strategic when promoting successful ageing. This study aimed to investigate whether components of successful ageing (i.e., diseases and complications, functions and engagement with life) differ according to hospitalisation experience in community-dwelling older adults.

METHODS

A secondary data analysis with the Korean national survey was performed. Using propensity score matching, 1812 older adults with hospitalisation experience were matched to 1812 older adults without hospitalisation experience. Sampling weight of the survey was considered for all statistical analyses.

RESULTS

The hospitalisation experienced group had more chronic illnesses, malnourishment, impairment in physical function, and depressive symptoms, and less activity in terms of working and social activities. There were no differences in cognitive function or religious activities.

CONCLUSIONS

Older adults with hospitalisation experience were less likely to experience successful ageing. To facilitate successful ageing of community-dwelling older adults with hospitalisation experience, nursing interventions for effective transitional care to encourage the use of community resources and participation in social activities are needed.

Cognitive deficit, physical frailty, hospitalization and emergency department visits in later life

OBJECTIVES

To examine the added effect of having both cognitive deficit and physical frailty, compared to having either one only, on hospitalization and emergency department (ED) visits.

METHODS

Data from a population-based study of 3,157 community-dwelling older (≥60 years) Chinese adults in the U.S. were used. Cognitive deficit was measured by the Mini-Mental State Examination (i.e. education-adjusted score: 16 [illiterate], 19 [primary school], and 23 [≥middle school]). Physical frailty was identified using the Short Performance Physical Battery (0-6 out of 15). The numbers of hospitalizations and ED visits in the previous two years were self-reported.

RESULTS

In this sample, 12.63% had cognitive deficit alone, 5.95% had physical frailty alone, and 4.26% had both. Compared with participants having neither cognitive deficit nor physical frailty, those having physical frailty alone were 1.5 times as likely to have hospitalizations (Rate Ratio [RR] = 1.52 [1.07, 2.16], p = 0.02) and ED visits (RR = 1.52 [1.07, 2.15], p = 0.02). Having cognitive deficit alone was not significantly related to either outcome. However, having cognitive deficit with existing physical frailty increased the likelihood of both hospitalization (RR = 2.00 [1.36, 2.96], p < 0.001) and ED visits (RR = 2.04 [1.37, 3.03], p < 0.001) to a greater extent than having physical frailty alone.

CONCLUSION

Having cognitive deficit alone was not significantly related to the likelihood of hospitalizations or ED visits, however having cognitive deficit with existing physical frailty increased the likelihood of both outcomes to a greater degree than having physical frailty alone. This suggests cognitive deficit and physical frailty have synergistic effects on hospitalizations and ED visits.
