Drivers and restrainers to adoption and spread of evidence-based health service delivery interventions: The case of CAPABLE.

CONTEXT: Very few programs improve physical function among older adults and those that do should achieve farther reach. METHODS: We used Force Field Analysis to examine drivers and restrainers for the CAPABLE program to impact the function of older adults throughout the United States. FINDINGS: We found 19 distinct drivers for CAPABLE. These include robust research findings demonstrating clinical and economic utility, expansion from an evidence-based program, grounding in theory, high value to older adults themselves, and common sense approach. A major policy environment shifting towards value-based payment and payer flexibility to experiment with social determinants significantly changed the perception of the program's value by key stakeholders. We found 8 distinct restrainers. CONCLUSIONS: Factors which drive and restrain CAPABLE provide lessons for other programs to move from research to sustainability. Policymakers, payers, and communities should look to proven programs as solutions to improve function for older adults and society.

Translating Knowledge into Action to Prevent Type 2 Diabetes: Medicare Expansion of the National Diabetes Prevention Program Lifestyle Intervention.

Policy Points Although preventable chronic conditions such as type 2 diabetes carry a significant cost and health burden, few lifestyle interventions have been scaled at a national policy level. The translation of the National Diabetes Prevention Program lifestyle intervention from research to a Medicare-covered service can serve as a model for national adoption of other interventions that have the potential to improve population health. The successful translation of the National Diabetes Prevention Program has depended on the collaboration of government agencies, academic researchers, community-based healthcare providers, payers, and other parties. CONTEXT: Many evidence-based health interventions never achieve national implementation. This article analyzes factors that supported the translation and national implementation of a lifestyle change intervention to prevent or delay type 2 diabetes in individuals with prediabetes. METHODS: We used the Knowledge to Action framework, which was developed to map how science is translated into effective health programs, to examine how the evidence-based intervention from the 2002 Diabetes Prevention Program trial was translated into the Centers for Disease Control and Prevention's large-scale National Diabetes Prevention Program, eventually resulting in payment for the lifestyle intervention as a Medicare-covered service. FINDINGS: Key findings of our analysis include the importance of a collaboration among researchers, policymakers, and payers to encourage early adopters; development of evidence-based, national standards to support widespread adoption of the intervention; and use of public input from community organizations to scale the intervention to a national level. CONCLUSIONS: This analysis offers timely lessons for other high-value, scalable interventions attempting to move beyond the evidence-gathering phase and into translation and institutionalization.

How Much Does Medication Nonadherence Cost the Medicare Fee-for-Service Program?

BACKGROUND: Medication adherence is associated with lower health care utilization and savings in specific patient populations; however, few empirical estimates exist at the population level. OBJECTIVE: The main objective of this study was to apply a data-driven approach to obtain population-level estimates of the impact of medication nonadherence among Medicare beneficiaries with chronic conditions. RESEARCH DESIGN: Medicare fee-for-service (FFS) claims data were used to calculate the prevalence of medication nonadherence among individuals with diabetes, heart failure, hypertension, and hyperlipidemia. Per person estimates of avoidable health care utilization and spending associated with medication adherence, adjusted for healthy adherer effects, from prior literature were applied to the number of nonadherent Medicare beneficiaries. SUBJECTS: A 20% random sample of community-dwelling, continuously enrolled Medicare FFS beneficiaries aged 65 years or older with Part D (N=14,657,735) in 2013. MEASURES: Avoidable health care costs and hospital use from medication nonadherence. RESULTS: Medication nonadherence for diabetes, heart failure, hyperlipidemia, and hypertension resulted in billions of Medicare FFS expenditures, millions in hospital days, and thousands of emergency department visits that could have been avoided. If the 25% of beneficiaries with hypertension who were nonadherent became adherent, Medicare could save $13.7 billion annually, with over 100,000 emergency department visits and 7 million inpatient hospital days that could be averted. CONCLUSION: Medication nonadherence places a large resource burden on the Medicare FFS program. Study results provide actionable information for policymakers considering programs to manage chronic conditions. Caution should be used in summing estimates across disease groups, assuming all nonadherent beneficiaries could become adherent, and applying estimates beyond the Medicare FFS population.

Trends in the Relationship Between Obesity and Disability, 1988-2012.

Rising obesity rates, coupled with population aging, have elicited serious concern over the impact of obesity on disability in later life. Prior work showed a significant increase in the association between obesity and disability from 1988 to 2004, calling attention to disability as a cost of longer lifetime exposure to obesity. It is not known whether this trend has continued. We examined functional impairment and impairment in activities of daily living (ADL) (defined as severe or moderate to severe) for adults aged 60 years or older (n = 16,770) over 3 time periods in the National Health and Nutrition Examination Survey. The relative odds of impairment for obese individuals versus normal-weight individuals significantly increased from period 1 (1988-1994) to period 2 (1999-2004) for all outcomes. In period 3 (2005-2012), this association remained stable for functional and severe ADL impairment and decreased for moderate-to-severe ADL impairment. The fraction of population disability attributable to obesity followed a similar trend. The trend of an increasing association between obesity and disability has leveled off in more recent years, and is even improving for some measures. These findings suggest that public health and policy concerns that obesity would continue to become more disabling over time have not been borne out.

Housing strain, mortgage foreclosure, and health.

BACKGROUND: Foreclosure rates have risen rapidly since 2005, reaching historically high levels. The purpose of this study was to examine the health implications of the current housing crisis. METHODS: We conducted a cross-sectional online consumer panel survey including residents of California, Arizona, Nevada, and Florida (n = 798) to determine the feasibility of contacting distressed homeowners via the Internet and to assess mental and physical health among respondents across the spectrum from those having no housing strain to those in loan default or home foreclosure. RESULTS: Homeowners in default or foreclosure exhibited poorer mental health and more physical symptoms than renters, homeowners with moderate strain, and homeowners with no strainöfollowing a gradient that was consistent across multiple health indicators. CONCLUSIONS: Internet panel sampling was an efficient method of contacting distressed homeowners. Record-high foreclosure rates may have broad implications for nursing and public health. Homeowners in default or foreclosure represent an identifiable high-risk group that may benefit from coordinated, affordable health and social services.

Mortgage delinquency and changes in access to health resources and depressive symptoms in a nationally representative cohort of Americans older than 50 years.

OBJECTIVES: We evaluated associations between mortgage delinquency and changes in health and health-relevant resources over 2 years, with data from the Health and Retirement Study, a longitudinal survey representative of US adults older than 50 years. METHODS: In 2008, participants reported whether they had fallen behind on mortgage payments since 2006 (n = 2474). We used logistic regression to compare changes in health (incidence of elevated depressive symptoms, major declines in self-rated health) and access to health-relevant resources (food, prescription medications) between participants who fell behind on their mortgage payments and those who did not. RESULTS: Compared with nondelinquent participants, the mortgage-delinquent group had worse health status and less access to health-relevant resources at baseline. They were also significantly more likely to develop incident depressive symptoms (odds ratio [OR] = 8.60; 95% confidence interval [CI] = 3.38, 21.85), food insecurity (OR = 7.53; 95% CI = 3.01, 18.84), and cost-related medication nonadherence (OR = 8.66; 95% CI = 3.72, 20.16) during follow-up. CONCLUSIONS: Mortgage delinquency was associated with significant elevations in the incidence of mental health impairments and health-relevant material disadvantage. Widespread mortgage default may have important public health implications.

Changes in weight at the end of life: characterizing weight loss by time to death in a cohort study of older men.

The purpose of this analysis was to characterize the natural history of weight change in the years prior to death among older persons and to examine how this pattern varies according to longevity and cause of death. Weight trajectories were analyzed by using data from 800 male decedents from the Baltimore Longitudinal Study of Aging (Maryland, 1958-2005) observed beginning an average of 19 years before death. A model including 3 distinct periods of weight change (weight stability/gain, mild weight loss, and accelerated weight loss before death) provided the best fit for all age-at-death groups. Approximately 9 years before death, the rate of weight loss increased to an average of 0.39 kg/year (P < 0.001) for all-cause mortality. For cancer deaths, weight loss accelerated significantly 3 years before death, regardless of age group. For cardiovascular deaths, the best-fitting inflection point increased with age, from 5 years for participants aged 60-69 years to 9-10 years before death for those aged 80 years or older. Results suggest that weight loss in older persons may begin earlier than previously believed. The duration of weight loss for noncancer deaths suggests that even distal changes in energy balance may be linked to risk of death.

Adipocytokines and the metabolic syndrome among older persons with and without obesity: the InCHIANTI study.

OBJECTIVES: Adipose tissue-derived inflammation may contribute to metabolic alterations and eventually to the metabolic syndrome (MetS). The purpose of this study was to: (1) examine the role of adipocytokines in the association between obesity and the MetS and (2) to determine whether the association is different in obese and non-obese persons. DESIGN: Cross-sectional population-based InCHIANTI study. SUBJECTS: A total of 944 community-dwelling adults aged 65 years and older living in Tuscany, Italy. MEASUREMENTS: Obesity was defined as body mass index > or =30 kg/m2 and MetS as > or =3 of the ATP-III criteria. Circulating levels of C-reactive protein, interleukin (IL)-6, IL-1 receptor antagonist (IL-1ra), IL-18, tumour necrosis factor (TNF)-alpha R1, adiponectin, resistin and leptin were measured. Additionally, insulin resistance was determined using the homeostasis model assessment (HOMA-IR). RESULTS: The prevalence of the MetS was 32%. Both overall and abdominal obesity were significantly associated with the MetS after adjusting for inflammatory cytokines, adipokines and lifestyle factors. After adjusting for multiple confounders and HOMA-IR, IL-1ra, TNF-alpha R1 and adiponectin (P < 0.05) remained significantly associated with the MetS. Having multiple cytokines in the highest tertile increased the likelihood of having the MetS in both obese (P for trend 0.002) and non-obese persons (P for trend 0.001) independent of insulin resistance. CONCLUSIONS: Non-obese and obese individuals who develop an intense pro-inflammatory state may be more prone to develop the MetS than those with lower levels of inflammation.

Foreclosure and health status.

In 2009, more than 2.8 million housing units in the U.S. received a foreclosure notice. That represents about 1 in every 45 properties and a 120% increase in the number of foreclosed properties since 2007. Real estate experts predict even more foreclosures in 2010 as high unemployment continues. The cascading effects of the foreclosure crisis on the U.S. economy are all too clear; the effects on individuals' health status are less obvious. This Issue Brief summarizes two studies that examine the health implications of foreclosure and reveal a vulnerable population that may benefit from coordinated health and financial services.

Material resources and population health: disadvantages in health care, housing, and food among adults over 50 years of age.

OBJECTIVES: We examined associations between material resources and late-life declines in health. METHODS: We used logistic regression to estimate the odds of declines in self-rated health and incident walking limitations associated with material disadvantages in a prospective panel representative of US adults aged 51 years and older (N = 15,441). RESULTS: Disadvantages in health care (odds ratio [OR] = 1.39; 95% confidence interval [CI] = 1.23, 1.58), food (OR = 1.69; 95% CI = 1.29, 2.22), and housing (OR = 1.20; 95% CI = 1.07, 1.35) were independently associated with declines in self-rated health, whereas only health care (OR = 1.43; 95% CI = 1.29, 1.58) and food (OR = 1.64; 95% CI = 1.31, 2.05) disadvantage predicted incident walking limitations. Participants experiencing multiple material disadvantages were particularly susceptible to worsening health and functional decline. These effects were sustained after we controlled for numerous covariates, including baseline health status and comorbidities. The relations between health declines and non-Hispanic Black race/ethnicity, poverty, marital status, and education were attenuated or eliminated after we controlled for material disadvantage. CONCLUSIONS: Material disadvantages, which are highly policy relevant, appear related to health in ways not captured by education and poverty. Policies to improve health should address a range of basic human needs, rather than health care alone.

Improving Social Needs Intervention Research: Key Questions for Advancing the Field.

Spurred by accumulated evidence documenting how social determinants of health shape health outcomes as well as the push for better value, the healthcare sector is embracing interventions that address patients' health-related social needs. An increasing number of healthcare organizations and payers are experimenting with strategies to identify needs and connect patients to resources that address identified needs with the goal of improving health outcomes, reducing avoidable utilization of costly health services, and improving health equity. Although many studies link social factors to health, relatively little published research exists about how the healthcare sector can effectively intervene to help identify and address social needs. This paper summarizes emerging evidence and identifies key areas where more research is needed to advance implementation and policy development. Although some healthcare-based social needs interventions have been shown to improve health and reduce avoidable utilization, important gaps remain in terms of comparative effectiveness and cost effectiveness of social needs intervention approaches. Additionally, the field would benefit from an increased understanding of mechanisms of action to maximize practitioners' ability to tailor interventions. More research is also needed to guard against unintended consequences and ensure these interventions reduce health inequities. Finally, implementation science research should identify supports and incentives for adoption of effective interventions. Focusing both public and private research efforts on these evidence gaps can help advance identification of interventions that maximize both health equity and healthcare value.

Inflammation and rate of cognitive change in high-functioning older adults.

BACKGROUND: Inflammatory proteins including interleukin-6 (IL-6) and C-reactive protein (CRP) have been associated with incident cognitive impairment, but little research has addressed their effects on the rate of cognitive change, and findings are mixed. The purpose of this study was to examine the relationship between serum levels of IL-6 and CRP and the rate of cognitive change across a range of cognitive domains in a sample of healthy older persons. METHODS: Growth curve analysis was performed on data from the MacArthur Study of Successful Aging, a longitudinal cohort study of high-functioning older adults aged 70-79 years at baseline in 1988 and reinterviewed in 1991 and 1995 (N = 851). Individual growth curve parameters were derived from baseline and follow-up performance in abstraction, language, spatial ability, verbal recall, spatial recognition, and global cognitive function based on age, IL-6, CRP, and covariates. RESULTS: Cross-sectionally, there is a generally linear negative relationship between inflammation and cognition, such that higher levels of inflammation are associated with lower levels of baseline cognitive function. After controlling for potential confounders, there was no effect of inflammation on baseline cognitive function or the rate of longitudinal cognitive change. However, persons in the top tertile on IL-6 were at an increased risk of incident declines on the Short Portable Mental Status Questionnaire (SPMSQ). CONCLUSIONS: Although high levels of inflammation are associated with incident cognitive impairment, these results do not generalize to the full range of cognitive changes, where the role of inflammation appears to be marginal.

Educational differentials in life expectancy with cognitive impairment among the elderly in the United States.

OBJECTIVE: This article provides estimates of education differentials in life expectancy with and without cognitive impairment for the noninstitutionalized population aged 70 years and older in the United States. METHOD: Life expectancy with cognitive impairment was calculated using multistate models, allowing transitions between cognitively intact and cognitively impaired states and from each of these states to death and allowing transition rates to vary across age and education. Four waves of the Assets and Health Dynamics of the Oldest Old survey were used. RESULTS: Those with low levels of education are more likely to become cognitively impaired and do so at an earlier age. After age 70, persons with low educational levels can expect to live 11.6 years, and persons with high education 14.1 years, without cognitive impairment. Length of life with cognitive impairment differs by education (1.6 years and 1.0 years at age 70, respectively) but differs little by age. DISCUSSION: Although those with higher education have lower rates of both cognitive impairment and mortality, those who do become cognitively impaired appear to be in poorer health, leading to a reduced probability of improved cognition and increased probability of mortality relative to those with lower educational levels.
