Abstract
Background and Objectives
Community Aging in Place, Advancing Better Living for Elders (CAPABLE) is an evidence-based intervention to promote aging in place. Although CAPABLE has been ...implemented in more than 40 community sites, wide variation in implementation exists. Guided by the Consolidated Framework for Implementation Research (CFIR), this study sought to determine key barriers and facilitators that may influence CAPABLE implementation with older adult and care partner dyads through an area agency on aging (AAA).
Research Design and Methods
A formative evaluation was completed using qualitative data from the pilot of a Hybrid Trial Type 1 study implementing CAPABLE in an AAA. Multiple sources of data were collected, including 2 focus groups, field notes, a tracking log, and meetings with CAPABLE interventionists. Data were analyzed using a framework method and validated through a negative case analysis approach in NVivo 12 Pro.
Results
Fourteen dyads enrolled in the pilot and 6 completed the CAPABLE intervention. Key themes aligned with 10 constructs from 5 domains of the CFIR. Facilitators included adaptability of the intervention, cost, networks and communication, and knowledge and belief of individuals. Barriers included intervention complexity, client needs and resources, and executing the planned process.
Discussion and Implications
Results enhance understanding of contextual factors that can influence the implementation of CAPABLE with care partners. Strategies to overcome barriers include simplifying recruitment materials and targeting older adults with recent onset of disability. The CFIR is a valuable resource for planning and evaluation of the implementation of evidence-based interventions to promote aging in place.
The devastating impact of the Sumatra tsunami of 26 December 2004, raised the question for scientists of how to forecast a tsunami threat. In 2005, the IOC-UNESCO XXIII assembly decided to implement ...a global tsunami warning system to cover the regions that were not yet protected, namely the Indian Ocean, the Caribbean and the North East Atlantic, the Mediterranean and connected seas (the NEAM region). Within NEAM, the Gulf of Cadiz is the more sensitive area, with an important record of devastating historical events. The objective of this paper is to present a preliminary design for a reliable tsunami detection network for the Gulf of Cadiz, based on a network of sea-level observatories. The tsunamigenic potential of this region has been revised in order to define the active tectonic structures. Tsunami hydrodynamic modeling and GIS technology have been used to identify the appropriate locations for the minimum number of sea-level stations. Results show that 3 tsunameters are required as the minimum number of stations necessary to assure an acceptable protection to the large coastal population in the Gulf of Cadiz. In addition, 29 tide gauge stations could be necessary to fully assess the effects of a tsunami along the affected coasts of Portugal, Spain and Morocco.
Earthquakes and tsunamis along Morocco's coasts have been reported since historical times. The threat posed by tsunamis must be included in coastal risk studies. This study focuses on the tsunami ...impact and vulnerability assessment of the Casablanca harbour and surrounding area using a combination of tsunami inundation numerical modelling, field survey data and geographic information system. The tsunami scenario used here is compatible with the 1755 Lisbon event that we considered to be the worst case tsunami scenario. Hydrodynamic modelling was performed with an adapted version of the Cornell Multigrid Coupled Tsunami Model from Cornell University. The simulation covers the eastern domain of the Azores-Gibraltar fracture zone corresponding to the largest tsunamigenic area in the North Atlantic. The proposed vulnerability model attempts to provide an insight into the tsunami vulnerability of building stock. Results in the form of a vulnerability map will be useful for decision makers and local authorities in preventing the community resiliency for tsunami hazards.
This single-group repeated-measures pilot study evaluated the effects of a 10-wk, multicomponent, best-practice exercise program on physical activity, performance of activities of daily living ...(ADLs), physical performance, and depression in community-dwelling older adults from low-income households (N = 15). Comparison of pretest and posttest scores using a one-tailed paired-samples t test showed improvement (p < .05) for 2 of 3 ADL domains on the Activity Measure-Post Acute Care and for 6 physical-performance measures of the Senior Fitness Test. Repeated-measures ANOVA revealed significant main effects for 3 of 8 physical activity measures using the Yale Physical Activity Scale. Retention rate was 78.9%, and the adherence rate for group sessions was 89.7%. Results suggest that participation in a multicomponent, best-practice physical activity program may positively affect sedentary, community-dwelling older adults' physical activity, ADL performance, and physical performance.
ABSTRACT
Introduction
Efforts to study performance fatigability have been limited because of measurement constrains. Accelerometry and advanced statistical methods may enable us to quantify ...performance fatigability more granularly via objective detection of performance decline. Thus, we developed the Pittsburgh Performance Fatigability Index (PPFI) using triaxial raw accelerations from wrist-worn accelerometer from two in-laboratory 400-m walks.
Methods
Sixty-three older adults from our cross-sectional study (mean age, 78 yr; 56% women; 88% White) completed fast-paced (
n
= 59) and/or usual-paced 400-m walks (
n
= 56) with valid accelerometer data. Participants wore ActiGraph GT3X+ accelerometers (The ActiGraph LLC, Pensacola, FL) on nondominant wrist during the walking task. Triaxial raw accelerations from accelerometers were used to compute PPFI, which quantifies percentage of area under the observed gait cadence-versus-time trajectory during a 400-m walk to a hypothetical area that would be produced if the participant sustained maximal cadence throughout the entire walk.
Results
Higher PPFI scores (higher score = greater fatigability) correlated with worse physical function, slower chair stands speed and gait speed, worse cardiorespiratory fitness and mobility, and lower leg peak power (|
ρ
| = 0.36–0.61 from fast-paced and |
ρ
| = 0.28–0.67 from usual-paced walks, all
P
< 0.05). PPFI scores from both walks remained associated with chair stands speed, gait speed, fitness, and mobility, after adjustment for sex, age, race, weight, height, and smoking status; PPFI scores from the fast-paced walk were associated with leg peak power.
Conclusions
Our findings revealed that the objective PPFI is a sensitive measure of performance fatigability for older adults and can serve as a risk assessment tool or outcome measure in future studies and clinical practice.
Abstract
Objective
Although decompressive laminectomy (DL) for lumbar spinal stenosis (LSS) is a common procedure among older adults, it is unclear whether surgical definitions of success translate ...into patient-defined success. Using goal attainment scaling (GAS) to compare goal achievement between individuals, we investigated the relationship between surgical-defined functional recovery and achievement of personalized goals in patients who underwent DL for LSS.
Participants
Twenty-eight community-dwelling veterans scheduled to undergo DL.
Methods
Participants were interviewed over the phone to set 1-year post-DL goals within 30 days before undergoing DL. Brigham Spinal Stenosis (BSS) score, comorbidities, cognitive function, and psychological factors also were assessed. GAS and BSS were repeated 1 year after DL. GAS scores were transformed into GAS-T scores (T-score transformation) to standardize achievement between patients and GAS-T change scores to compare study variables.
Results
Seventeen of 28 participants had successful DL outcomes by BSS standards, though none of the participants achieved all of their GAS goals, with follow-up GAS-T scores averaging 44.5 ± 16.8. All three BSS scales positively correlated with GAS-T change scores: severity change r = 0.52, P = 0.005; physical function change r = 0.51, P = 0.006; and satisfaction r = 0.70, P < 0.001. Covariate analysis revealed a negative correlation between GAS-T change score and fear-avoidance beliefs: r = -0.41, P = -0.029.
Conclusion
There was congruent validity between GAS and the BSS in older veterans undergoing DL for LSS. Given the need for patient-centered care in older adults, future investigations exploring GAS in larger studies that target additional pain conditions and include participants with greater demographic diversity are warranted.
The Pittsburgh Performance Fatigability Index (PPFI) quantifies the percent decline in cadence using accelerometry during standardized walking tasks. Although PPFI has shown strong correlations with ...physical performance, the developmental sample was relatively homogenous and small, necessitating further validation.
Participants from the Study of Muscle, Mobility and Aging (N = 805, age = 76.4 ± 5.0 years, 58% women, 85% White) wore an ActiGraph GT9X on the nondominant wrist during usual-paced 400 m walk. Tri-axial accelerations were analyzed to compute PPFI (higher score = greater fatigability). To evaluate construct and discriminant validity, Spearman correlations (rs) between PPFI and gait speed, Short Physical Performance Battery (SPPB), chair stand speed, leg peak power, VO2peak, perceived fatigability, and mood were examined. Sex-specific PPFI cut-points that optimally discriminated gait speed using classification and regression tree were then generated. Their discriminate power in relation to aforementioned physical performance were further evaluated.
Median PPFI score was 1.4% (25th-75th percentile range: 0%-21.7%), higher among women than men (p < .001). PPFI score was moderate-to-strongly correlated with gait speed (rs = -0.75), SPPB score (rs = -0.38), chair stand speed (rs = -0.36), leg peak power (rs = -0.34) and VO2peak (rs = -0.40), and less strongly with perceived fatigability (rs = 0.28-0.29), all p < .001. PPFI score was not correlated with mood (|rs| < 0.08). Sex-specific PPFI cut-points (no performance fatigability: PPFI = 0%; mild performance fatigability: 0% < PPFI < 3.5% women, 0% < PPFI < 5.4% men; moderate-to-severe performance fatigability: PPFI ≥ 3.5% women, PPFI ≥ 5.4% men) discriminated physical performance (all p < .001), adjusted for demographics and smoking status.
Our work underscores the utility of PPFI as a valid measure to quantify performance fatigability in future longitudinal epidemiologic studies and clinical/pharmaceutical trials.
We examined the feasibility and benefit of integrating occupational therapy into a long-term services and supports (LTSS) care coordination program for aging in place.
Clients referred to ...occupational therapy during a 16-wk trial were evaluated with the In-Home Occupational Performance Evaluation and received education on strategies for aging in place. Clients who indicated readiness for change were assisted in setting personalized goals with goal attainment scaling and received four additional occupational therapy visits.
Of the program's feasibility benchmarks, 87% were met. Twenty-three clients were referred, and 16 clients were evaluated; 37.5% of those evaluated indicated readiness for change, establishing 18 goals with 100% goal attainment.
Integration of occupational therapy into an LTSS care coordination program was feasible. Benefits of adding occupational therapy included a performance-based evaluation that revealed personal factors as barriers to aging in place and gave access to a client-centered service to maximize independence.
Reducing prolonged engagement in sedentary behavior is increasingly considered a viable pathway to older-adult health and continued functional ability. Community-based programs that aim to increase ...physical activity can improve programs' acceptability by integrating older adults' perspectives on sedentary behavior and healthy aging into their design. The purpose of this study was to better understand the perceptions of a diverse group of community-dwelling older adults regarding sedentary behavior and its influence on healthy aging. Six focus group discussions with forty-six participants took place across two senior centers in New York City. Self-report questionnaires about daily activity patterns, general health status, and typical sedentary behaviors were also completed by the participants and analyzed using descriptive statistics. The focus group discussions were audio-recorded, transcribed, and analyzed using inductive and deductive approaches and an ecological framework to identify salient themes. A qualitative analysis revealed that the participants were aware of the physical costs of engaging in prolonged sedentary behavior. However, many routine sedentary activities were perceived to be health-promoting and of psychological, cognitive, or social value. The insights gained can inform the development of senior-center programs and health-promotion messaging strategies that aim to reduce older adults' sedentary behavior.
