Evaluation of aging in place model with home care services and registered nurse care coordination in senior housing

Longitudinal analysis of aging in place at TigerPlace: Resident function and well-being

This paper reports on a longitudinal eight-year analysis (2011-2019) of trajectory of function and well-being residents of TigerPlace Aging in Place (AIP) model of care. Residents were routinely assessed using standard health assessment instruments. Average scores from each measure were examined for changes or trends in resident function; decline over time was calculated. Scores for depression, mental health subscale Short Form Health Survey-12 (SF-12) remained stable over time. Mini Mental State Exam declined to mild dementia range (21-24). Physical measures SF-12 physical health subscale, ADLs, and IADLs declined slightly, while fall risk increased over time. When yearly trends in AIP were modeled with a referent group there was no significant worsening of functioning. The length of stay for TigerPlace residents continued to remain stable at nearly 30 months. Residents maintained function in the environment of their choice longer at cost less than nursing homes, and just above residential care cost.

Technology for Healthy Independent Living: Creating a Tailored In-Home Sensor System for Older Adults and Family Caregivers

Sensing technologies hold enormous potential for early detection of health changes that can dramatically affect the aging experience. In previous work, we developed a health alert system that captures and analyzes in-home sensor data. The purpose of this research was to collect input from older adults and family members on how the health information generated can best be adapted, such that older adults and family members can better self-manage their health. Five 90-minute focus groups were conducted with 23 older adults (mean age = 80 years; 87% female) and five family members (mean age = 64; 100% female). Participants were asked open-ended questions about the sensor technology and methods for interacting with their health information. Participants provided feedback regarding tailoring the technology, such as delegating access to family and health care providers, receiving health messages and alerts, interpreting health messages, and graphic display options. Participants also noted concerns and future likelihood of technology adoption. [Journal of Gerontological Nursing, 46(7), 35-40.].

Nursing Care Coordination for Patients with Complex Needs in Primary Healthcare: A Scoping Review

Introduction:

Millions of people worldwide have complex health and social care needs. Care coordination for these patients is a core dimension of integrated care and a key responsibility for primary healthcare. Registered nurses play a substantial role in care coordination. This review draws on previous theoretical work and provides a synthesis of care coordination interventions as operationalized by nurses for complex patient populations in primary healthcare.

Methodology:

We followed Arksey and O’Malley’s methodological framework for scoping reviews. We carried out a systematic search across CINAHL, MEDLINE, Scopus and ProQuest. Only empirical studies were included. We performed a thematic analysis using deductive (the American Nurses Association Framework) and inductive approaches. Findings were discussed with a group of experts.

Results:

Thirty-four articles were included in the synthesis. Overall, nursing care coordination activities were synthesized into three categories: those targeting the patient, family and caregivers; those targeting health and social care teams; and those bringing together patients and professionals. Interpersonal communication and information transfer emerged as cross-cutting activities that support every other activity. Our results also brought to light the nurses’ contribution to care coordination efforts for patients with complex needs as well as critical components that should be present in every care coordination intervention for this clientele. These include an increased intensity and frequency of activities, relational continuity of care, and home visits.

Conclusion:

With the growing complexity of patient’s needs, efforts must be directed towards enabling the primary healthcare level to effectively play its substantial role in care coordination. This includes finding primary care employment models that would facilitate multidisciplinary teamwork and the delivery of integrated care, and guarantee the delivery of intensive yet efficient coordinated care.

Impact of Time to Receipt of Prosthesis on Total Healthcare Costs 12 Months Postamputation

OBJECTIVE

The objective was to assess the impact of a prosthesis and the timing of prosthesis receipt on total direct healthcare costs in the 12-mo postamputation period.

DESIGN

Data on patients with lower limb amputation (n = 510) were obtained from a commercial claims database for retrospective cohort analysis. Generalized linear multivariate modeling was used to determine differences in cost between groups according to timing of prosthesis receipt compared with a control group with no prosthesis.

RESULTS

Receipt of a prosthesis between 0 and 3 mos post lower limb amputation yielded a reduced total cost by approximately 0.23 in log scale within 12 mos after amputation when compared with the no-prosthesis group. Despite the included costs of a prosthesis, individuals who received a prosthesis either at 4-6 mos postamputation or 7-9 mos postamputation incurred costs similar to the no-prosthesis group.

CONCLUSION

Earlier receipt of a prosthesis is associated with reduced spending in the 12 mos postamputation of approximately $25,000 compared with not receiving a prosthesis. The results of this study suggest that not providing or delaying the provision of a prosthesis increases costs by about 25%.

Human-centered approaches that integrate sensor technology across the lifespan: Opportunities and challenges

Children, parents, older adults, and caregivers routinely use sensor technology as a source of health information and health monitoring. The purpose of this paper is to describe three exemplars of research that used a human-centered approach to engage participants in the development, design, and usability of interventions that integrate technology to promote health. The exemplars are based on current research studies that integrate sensor technology into pediatric, adult, and older adult populations living with a chronic health condition. Lessons learned and considerations for future studies are discussed. Nurses have successfully implemented interventions that use technology to improve health and detect, prevent, and manage diseases in children, families, individuals and communities. Nurses are key stakeholders to inform clinically relevant health monitoring that can support timely and personalized intervention and recommendations.

Examining Community-Based Housing Models to Support Aging in Place: A Scoping Review

BACKGROUND AND OBJECTIVES

With the global population aging, there is demand for older adults to age in place, that is, to live and age well in their home and community with some level of independence. Community-based housing models exist and may support this process. This scoping review aimed to describe and synthesize the ways in which community-based housing models relate to older adults' aging in place and identify strengths and gaps in the literature.

RESEARCH DESIGN AND METHODS

The housing models explored were: villages; naturally occurring retirement communities; congregate housing and co-housing; sheltered housing; and continuing care retirement communities. This exploratory scoping review examined international peer-reviewed literature published from 2004-2019. Six databases were searched using terms related to housing models and older adults. Forty-six articles met the inclusion criteria. Descriptive numerical summary and thematic analysis were used to synthesize study characteristics and findings.

RESULTS

Our analysis revealed four themes relating to aging in place in the housing models: Social Relations, Health and Well-being, Sense of Self and Autonomy, and Activity Participation. Further analysis identified housing-specific characteristics that appeared to pose barriers to, or enable, aging in place.

DISCUSSION AND IMPLICATIONS

To best support aging in place, the findings of the review suggest multiple characteristics worth considering when developing or relocating to a community-based housing model. Further research is required to understand how facilitating characteristics can promote aging in place for community-dwelling older adults.

Case Management Models and Continuing Care: A Literature Review across nations, settings, approaches, and assessments

Older adults accessing continuing care often have multiple chronic conditions. Research suggests that case management is a promising approach to reduce health care expenditure and improve patient outcomes. To optimize healthcare delivery, an examination of existing case management models and their effectiveness is essential. This literature review was conducted using Joanna Briggs Institute (JBI) methods to explore case management models for older adults accessing continuing care services. Searches were conducted in PubMed and CINAHL from 2010 to 2018. A total of 37 articles were included in this review. Approaches to case management are diverse with respect to composition of care providers, method of care provision, and location of care. Findings from 27 quantitative studies demonstrated that nurse-led and interdisciplinary team case management models that include home visits can effectively reduce hospital admission/readmission while lowering costs. Mixed results were found on the impact of case management on patient satisfaction, ED visits, quality of life, length of stay, self-efficacy, social integration and caregiver burden. Among 10 qualitative studies, 3 facilitators for quality case management were identified that include receiving care at home, building trusting relationships, and improving self-efficacy. Based on these findings, we conclude that nurse-led and interdisciplinary team case management can effectively reduce hospital admission of frail older adults while lowering costs, particularly within home care settings.

Effectiveness of a health-social partnership program for discharged non-frail older adults: a pilot study

Background

Previous studies supporting discharged patients are hospital-based which admission criteria tend to include mainly those with complex needs and/or specific disease conditions. This study captured the service gap where these non-frail older patients might have no specific medical problem upon discharge but they might encounter residual health and social issues when returning home.

Methods

Discharged community-dwelling non-frail older adults from an emergency medical ward were recruited and randomized into either intervention (n = 37) or control (n = 38) group. The intervention group received a 12-week complex interventions that included structured assessment, health education, goal empowerment, and care coordination supported by a health-social team. The control group received usual discharge care and monthly social call. The primary outcome was health-related quality of life (HRQoL). Secondary outcomes included activities of daily living (ADL), the presence of depressive symptoms, and the use of health services. The outcomes were measured at pre-intervention (T1) and at three months post-intervention (T2). The independent t-test or the Mann-Whitney U test was used to analyze the group differences in HRQoL, ADL, and presence of depressive symptoms according to the normality of data.

Results

Analysis showed that the intervention group experienced a statistically significantly improvement in the mental component scale of quality of life (p = .036), activities of daily living (p = .005), and presence of depressive symptoms (p = .035) at T2 compared with at T1. No significant differences were found in the control group.

Conclusions

Supporting self-care is necessary to enable community-dwelling non-frail older adults to be independent to the fullest extent possible in the community. The promising results found in this pilot study suggested that the integration of the health-social partnership into transitional care practice is effective and can be sustained in the community. Future studies can draw on these findings and maximize the integrated care quality during the transition phase.

Important Elements and Features of Neighborhood Landscape for Aging in Place: A Study in Hong Kong

With rapid growth in the aging population around the world, the promotion of aging in place has become more significant in recent years. Many neighborhood landscape elements and features have been revealed by accumulating research findings to be critical to aging in place. However, they are usually studied separately or in small groups. Little has been done to examine the relative importance of these elements and features when brought together, from the older adult's point of view. In this context, the current study investigated the perceived importance for older adults of 22 selected neighborhood landscape elements and features. A questionnaire survey was conducted in 17 public rental housing estates in Hong Kong with proportions of older residents (aged 65 or above) between 20 and 40%. According to the 426 collected samples, older adults considered as highly important landscape elements and features that contribute to comfort and help them avoid hazards, such as good ventilation, protection from severe sunshine/rain, body support, and good hygiene, while elements were thought to potentially bring hazards while not being necessities for older adults' outdoor experience were considered least important, including portable chairs, outdoor tables, plants that can be touched, closeness to children's playgrounds, small spaces for solitude, water features, and fitness equipment. After integrally interpreting the findings regarding perceived importance with other collected data, some landscape design suggestions are generated to supplement existing guidelines and recommendations concerning older adults' well-being and quality of life. These findings can inspire future research and landscape design that prioritize promoting aging in place.

Systematic review of the physical home environment and the relationship to psychological well-being among community-dwelling older adults

Older adults with functional impairments are at risk of being excluded from participation in day-to-day life. This exclusion can have detrimental effects on psychological well-being. The physical home environment is a potential force for both enhancing and limiting participation for this population. This systematic review of literature examined relationships between the physical home environment, functional impairment, and psychological well-being among older adults who live in community settings. The Ecological Model of Aging served as the guiding framework for this review. Results suggest that knowledge of the relationships between these constructs is still in the early stages. While associational relationships are established, the nature of these relationships is clouded by the inconsistency of measurement across studies, as well as design challenges. Objective and subjective features of the physical home environment are linked to psychological well-being throughout the literature. A growing body of evidence demonstrates that personal competence serves as a moderator of those relationships.

Sexual culture in low-income older adult housing: norms, behaviours and risks

This paper explores the behaviours and meanings associated with intimacy and sexuality among older adults with diverse partners living in subsidised senior housing. It utilises survey and qualitative data from a mixed methods of ageing/HIV exposure to illustrate gendered views on sexual and intimate behaviours, and attitudes towards transactional/commercial sex. Data suggest that women were cautious about engaging in intimate relationships, while men sought them and the companionship they provided to address loneliness. Reasons for non-intimacy were age and health problems. Generally speaking, both men and women had positive attitudes towards sex. Men took risks by having multiple partners and using condoms irregularly; women believed they could avoid risks by taking time to get to know their partners, but never used condoms. Forty per cent of men who saw sex workers were not regular condom users. They traded risk of gossip, violence and infection for companionship with women seeking money and physical safety. Findings have implications for policies, counselling and interventions for older sexually active adults in institutional and residential settings.

Holistic Wellness in Older Adulthood: Group Differences Based on Age and Mental Health

PURPOSE

To understand how demographic variables and depression symptoms relate to the prevalence of wellness, resilience, and age perception within a sample of community-dwelling older adults.

DESIGN

In all, 200 residents across 12 senior housing sites were surveyed. Research questions included the following: (1) Do group differences exist in wellness, resilience, and age perception based on age, sex, race, education, and depression symptoms? (2) Which profile of variables is most strongly associated with self-rated depression among older adults?

METHOD

Multivariate analyses of variance were used to examine group differences. A discriminant analysis demonstrated which variables comprised the profile of individuals who ascribed to depression symptoms.

FINDINGS

Younger respondents (i.e., age 55-70) had significantly lower levels of wellness (η² = .034) and resilience (η² = .052). Respondents suffering from depression symptoms had lower levels of wellness (η² = .155), resilience (η² = .163), and positive age perception (η² = .067) and higher rates of negative age perception (η² = .052). The discriminant analysis correctly categorized 75.3% of the cases related to depression symptoms, and resilience and certain forms of wellness were most relevant.

CONCLUSIONS

The current study sheds light into within-group differences in wellness, resilience, and age perception that depend on variables such as age and depression.

Older Adults' Perceptions of and Preferences for a Fall Risk Assessment System: Exploring Stages of Acceptance Model

Aging in place is a preferred and cost-effective living option for older adults. Research indicates that technology can assist with this goal. Information on consumer preferences will help in technology development to assist older adults to age in place. The study aim was to explore the perceptions and preferences of older adults and their family members about a fall risk assessment system. Using a qualitative approach, this study examined the perceptions, attitudes, and preferences of 13 older adults and five family members about their experience living with the fall risk assessment system during five points in time. Themes emerged in relation to preferences and expectations about the technology and how it fits into daily routines. We were able to capture changes that occurred over time for older adult participants. Results indicated that there was acceptance of the technology as participants adapted to it. Two themes were present across the five points in time-safety and usefulness. Five stages of acceptance emerged from the data from preinstallation to 2 years postinstallation. Identified themes, stages of acceptance, and design and development considerations are discussed.

Randomized Trial of Intelligent Sensor System for Early Illness Alerts in Senior Housing

OBJECTIVES

Measure the clinical effectiveness and cost effectiveness of using sensor data from an environmentally embedded sensor system for early illness recognition. This sensor system has demonstrated in pilot studies to detect changes in function and in chronic diseases or acute illnesses on average 10 days to 2 weeks before usual assessment methods or self-reports of illness.

DESIGN

Prospective intervention study in 13 assisted living (AL) communities of 171 residents randomly assigned to intervention (n=86) or comparison group (n=85) receiving usual care.

METHODS

Intervention participants lived with the sensor system an average of one year.

MEASUREMENTS

Continuous data collected 24 hours/7 days a week from motion sensors to measure overall activity, an under mattress bed sensor to capture respiration, pulse, and restlessness as people sleep, and a gait sensor that continuously measures gait speed, stride length and time, and automatically assess for increasing fall risk as the person walks around the apartment. Continuously running computer algorithms are applied to the sensor data and send health alerts to staff when there are changes in sensor data patterns.

RESULTS

The randomized comparison group functionally declined more rapidly than the intervention group. Walking speed and several measures from GaitRite, velocity, step length left and right, stride length left and right, and the fall risk measure of functional ambulation profile (FAP) all had clinically significant changes. The walking speed increase (worse) and velocity decline (worse) of 0.073 m/s for comparison group exceeded 0.05 m/s, a value considered to be a minimum clinically important difference. No differences were measured in health care costs.

CONCLUSIONS

These findings demonstrate that sensor data with health alerts and fall alerts sent to AL nursing staff can be an effective strategy to detect and intervene in early signs of illness or functional decline.

Ageing out of place: The meaning of home among hispanic older persons living in the United States

AIM

To explore the meaning of home among older Hispanic immigrants who are "aging out of place."

BACKGROUND

Emerging evidence supports the concept of older persons ageing in place. Nurse researchers have demonstrated that older person who age in place have better physical, psychological and cognitive outcomes. Less, however, is known about older persons who are "aging out of place," meaning out of their country of origin. With the growth of home health care, there is a need to understand the older immigrants' meaning of home when ageing out of their country of origin.

DESIGN AND METHOD

An inductive, qualitative descriptive research design was used. Seventeen Hispanic participants, ranging in age from 65 to 83 years were interviewed using a semi-structured interview protocol.

FINDINGS

Two major finding of the study focused on participants' descriptions of home in their country of origin and in the USA. The majority of participants described their home in their native country as the community, countryside or town (pueblo) and in the U.S.A. as family. The level of social isolation and loneliness among participants was evident.

CONCLUSIONS

Older Hispanic immigrants who are "aging out of place" integrate their past experiences of sense of place in their native country with their present experiences of home in the USA. The need to understand the role of the community and the family in the provision of nursing care in the home may be more important than the physical structure or setting in which it is delivered. Further intra- and cross-national studies are needed to provide a framework for understanding the issues of ageing and immigration globally.

IMPLICATIONS FOR PRACTICE

Gerontological nurses need to recognise the complexity of family relationships for older Hispanic persons who are ageing out of place of origin and their risk of depression, social isolation, and loneliness.

An Indoor Positioning System Based on Wearables for Ambient-Assisted Living

The urban population is growing at such a rate that by 2050 it is estimated that 84% of the world’s population will live in cities, with flats being the most common living place. Moreover, WiFi technology is present in most developed country urban areas, with a quick growth in developing countries. New Ambient-Assisted Living applications will be developed in the near future having user positioning as ground technology: elderly tele-care, energy consumption, security and the like are strongly based on indoor positioning information. We present an indoor positioning system for wearable devices based on WiFi fingerprinting. Smart-watch wearable devices are used to acquire the WiFi strength signals of the surrounding Wireless Access Points used to build an ensemble of Machine Learning classification algorithms. Once built, the ensemble algorithm is used to locate a user based on the WiFi strength signals provided by the wearable device. Experimental results for five different urban flats are reported, showing that the system is robust and reliable enough for locating a user at room level into his/her home. Another interesting characteristic of the presented system is that it does not require deployment of any infrastructure, and it is unobtrusive, the only device required for it to work is a smart-watch.

Automated In-Home Fall Risk Assessment and Detection Sensor System for Elders

PURPOSE OF THE STUDY

Falls are a major problem for the elderly people leading to injury, disability, and even death. An unobtrusive, in-home sensor system that continuously monitors older adults for fall risk and detects falls could revolutionize fall prevention and care.

DESIGN AND METHODS

A fall risk and detection system was developed and installed in the apartments of 19 older adults at a senior living facility. The system includes pulse-Doppler radar, a Microsoft Kinect, and 2 web cameras. To collect data for comparison with sensor data and for algorithm development, stunt actors performed falls in participants' apartments each month for 2 years and participants completed fall risk assessments (FRAs) using clinically valid, standardized instruments. The FRAs were scored by clinicians and recorded by the sensing modalities. Participants' gait parameters were measured as they walked on a GAITRite mat. These data were used as ground truth, objective data to use in algorithm development and to compare with radar and Kinect generated variables.

RESULTS

All FRAs are highly correlated (p < .01) with the Kinect gait velocity and Kinect stride length. Radar velocity is correlated (p < .05) to all the FRAs and highly correlated (p < .01) to most. Real-time alerts of actual falls are being sent to clinicians providing faster responses to urgent situations.

IMPLICATIONS

The in-home FRA and detection system has the potential to help older adults remain independent, maintain functional ability, and live at home longer.

[The influence of minority sociolinguistic context on home support for seniors in a rural devitalized area: the case of Acadieville New Brunswick]

New Brunswick is one of the provinces most affected by the aging of the population. Moreover, aging at home in Francophone minority communities is a major challenge in rural areas. The goal of this paper is to identify the main advantages and disadvantages of aging at home and to expose organizational strategies deployed by seniors and their families in order to promote aging in place. The case study is the method of analysis that we have recommended. Our methodology is based on content analysis of 13 semi-structured interviews with seniors and their children. The results show that family and community support, resourcefulness and resiliency, the practice of leisure activities as well as the living environment are among the principal means used by older adults to promote aging at home.

Aging in place: merging desire with reality

Barriers to aging in place include physical mobility and transportation limitations, isolation related loneliness and depression, diminishing health status, housing quality, finances, and caregiving resources. The scope of the aging demographic shift, economic consequences and loss of quality of life urge adoption of such successful approaches as the life course model. Desirable aging in place provides person-centered quality of living that is independence-effective and affordable. Systematic community-centered and person-centered approaches are crucial to accomplishing the central actions of the life course model. Not only are the actions necessary, they are interactive, interdependent, and strategic in supporting one another.

The continued success of registered nurse care coordination in a state evaluation of aging in place in senior housing

Older adults prefer to age in place, remaining in their home as their health care needs intensify. In a state evaluation of aging in place (AIP), the University of Missouri Sinclair School of Nursing and Americare System Inc, Sikeston, MO, developed an elder housing facility to be an ideal housing environment for older adults to test the AIP care delivery model. An evaluation of the first 4 years (2005-2008) of the AIP program at TigerPlace (n = 66) revealed that the program was effective in restoring health and maintaining independence while being cost-effective. Similar results evaluating the subsequent 4 years (2009-2012) of the program (N = 128) revealed positive health outcomes (fall risk, gait velocity, Functional Ambulation Profile, handgrips, Short-Form 12 Physical Health, Short-Form 12 Mental Health, and Geriatric Depression Scale); slightly negative activities of daily living, independent activities of daily living, and Mini-Mental State Examination; and positive cost-effectiveness results. Combined care and housing costs for any resident who was receiving additional care services and qualified for nursing home care (n = 44) was about $20,000 less per year per person than nursing home care. Importantly, residents continued to live in private apartments and were encouraged to be as independent as possible through the end of life.

Evaluation of health alerts from an early illness warning system in independent living

Passive sensor networks were deployed in independent living apartments to monitor older adults in their home environments to detect signs of impending illness and alert clinicians so they can intervene and prevent or delay significant changes in health or functional status. A retrospective qualitative deductive content analysis was undertaken to refine health alerts to improve clinical relevance to clinicians as they use alerts in their normal workflow of routine care delivery to older adults. Clinicians completed written free-text boxes to describe actions taken (or not) as a result of each alert; they also rated the clinical significance (relevance) of each health alert on a scale of 1 to 5. Two samples of the clinician's written responses to the health alerts were analyzed after alert algorithms had been adjusted based on results of a pilot study using health alerts to enhance clinical decision-making. In the first sample, a total of 663 comments were generated by seven clinicians in response to 385 unique alerts; there are more comments than alerts because more than one clinician rated the same alert. The second sample had a total of 142 comments produced by three clinicians in response to 88 distinct alerts. The overall clinical relevance of the alerts, as judged by the content of the qualitative comments by clinicians for each alert, improved from 33.3% of the alerts in the first sample classified as clinically relevant to 43.2% in the second. The goal is to produce clinically relevant alerts that clinicians find useful in daily practice. The evaluation methods used are described to assist others as they consider building and iteratively refining health alerts to enhance clinical decision making.

Sensor technology to support Aging in Place

Older adults want to age in place at home. Sensor technology has the potential to help by monitoring individuals' health status, detecting emergency situations, and notifying health care providers. Researchers at the University of Missouri are investigating the impact of registered nurse care coordination and technology on the ability of older adults to age in place. Technology coupled with care coordination has improved clinical outcomes. This article presents an overview of the Aging in Place research, TigerPlace as a Missouri-sponsored Aging in Place facility, and the sensor technology developed to support Aging in Place.

In-home fall risk assessment and detection sensor system

Falls are a major problem in older adults. A continuous, unobtrusive, environmentally mounted (i.e., embedded into the environment and not worn by the individual), in-home monitoring system that automatically detects when falls have occurred or when the risk of falling is increasing could alert health care providers and family members to intervene to improve physical function or manage illnesses that may precipitate falls. Researchers at the University of Missouri Center for Eldercare and Rehabilitation Technology are testing such sensor systems for fall risk assessment (FRA) and detection in older adults' apartments in a senior living community. Initial results comparing ground truth (validated measures) of FRA data and GAITRite System parameters with data captured from Microsoft(®) Kinect and pulse-Doppler radar are reported.

Cost effectiveness of a home-based intervention that helps functionally vulnerable older adults age in place at home

Evaluating cost effectiveness of interventions for aging in place is essential for adoption in service settings. We present the cost effectiveness of Advancing Better Living for Elders (ABLE), previously shown in a randomized trial to reduce functional difficulties and mortality in 319 community-dwelling elders. ABLE involved occupational and physical therapy sessions and home modifications to address client-identified functional difficulties, performance goals, and home safety. Incremental cost-effectiveness ratio (ICER), expressed as additional cost to bring about one additional year of life, was calculated. Two models were then developed to account for potential cost differences in implementing ABLE. Probabilistic sensitivity analyses were conducted to account for variations in model parameters. By two years, there were 30 deaths (9: ABLE; 21: control). Additional costs for 1 additional year of life was $13,179 for Model 1 and $14,800 for Model 2. Investment in ABLE may be worthwhile depending on society's willingness to pay.
