Multicenter Study Observational Study
30-Day Emergency Department Revisit Rates among Older Adults with Documented Dementia.
Published literature on national emergency department (ED) revisit rates among older adults with dementia is sparse, despite anecdotal evidence of higher ED utilization. Thus we evaluated the odds ratio (OR) of 30-day ED revisits among older adults with dementia using a nationally representative sample. ⋯ Dementia diagnoses were a significant predictor of 30-day ED revisits. Further research should assess potential reasons why dementia is associated with markedly higher revisit rates, as well as opportunities to manage and transition dementia patients from the ED back to the community more effectively.

Regular physical activity (PA) has been associated with improved cognitive function, but its effect on postoperative delirium (POD) has not been established. Our objectives were to determine the effect of baseline PA on the incidence of POD in older patients undergoing elective orthopedic surgery and to determine whether these effects were independent of cognitive reserve. We hypothesize that PA protects against POD by bolstering physiologic reserve needed to withstand the stressors of surgery. ⋯ Regular PA is associated with decreased incidence of POD, especially among women. Future studies should address the basis of sex differences in PA benefits on delirium. J Am Geriatr Soc 67:2260-2266, 2019.

Develop and validate a modified frailty phenotype measure for older Mexican Americans participating in the Hispanic Established Populations for the Epidemiological Study of the Elderly (H-EPESE) and related studies. ⋯ "Limitations in walking half a mile" can be used as a substitute criterion for "low physical activity" in assessing frailty. The modified frailty phenotype measure was comparable with the original frailty phenotype measure in H-EPESE participants over time. Our results indicate the modified frailty phenotype is a useful longitudinally frailty measure for community-dwelling older Mexican Americans. J Am Geriatr Soc 67:2393-2397, 2019.

How Do Frail Medicare Beneficiaries Fare Under Bundled Payments?
Bundled payments are an alternative payment model in which a hospital takes accountability for the costs of a 90-day episode of care. Such models are meant to improve care through better coordination across care settings, but could have adverse consequences for frail adults if they lead to inappropriate cuts in necessary post-acute care. ⋯ While frail patients had higher costs and worse outcomes in general, there was no evidence of changes in access or worsening clinical outcomes in BPCI hospitals for frail patients relative to the nonfrail in hospitals' first year of participation in the program. These findings may be reassuring for policy makers and clinical leaders. J Am Geriatr Soc 67:2245-2253, 2019.

Prospectively collected data on postoperative delirium (POD) after transcatheter aortic valve implantation (TAVI) are scarce. The aim of this study was to report the incidence and risk factors of delirium after TAVI under general anesthesia and to assess the association of POD with clinical outcome and short- and long-term survival. ⋯ One in six patients experienced POD after TAVI under general anesthesia. POD was the strongest predictor of long-term mortality and was associated with impaired short- and long-term survival. Prior delirium and a more calcified aortic valve were the strongest independent predictors of POD. J Am Geriatr Soc 67:2325-2330, 2019.
