Epidemiology of the Homebound Population in the United States

IMPORTANCE

Increasing numbers of older, community-dwelling adults have functional impairments that prevent them from leaving their homes. It is uncertain how many people who live in the United States are homebound.

OBJECTIVES

To develop measures of the frequency of leaving and ability to leave the home and to use these measures to estimate the size of the homebound population in the US population.

DESIGN, SETTING, AND PARTICIPANTS

Cross-sectional data from the National Health and Aging Trends Study collected in 2011 in the contiguous United States. Participants were a nationally representative sample of 7603 noninstitutionalized Medicare beneficiaries 65 years and older.

MAIN OUTCOMES AND MEASURES

We defined homebound persons as those who never (completely homebound) or rarely (mostly homebound) left the home in the last month. We defined semihomebound persons as those who only left the home with assistance or had difficulty or needed help leaving the home. We compared demographic, clinical, and health care utilization characteristics across different homebound status categories.

RESULTS

In 2011, the prevalence of homebound individuals was 5.6% (95% CI, 5.1%-6.2%), including an estimated 395,422 people who were completely homebound and 1,578,984 people who were mostly homebound. Among semihomebound individuals, the prevalence of those who never left home without personal assistance was 3.3% (95% CI, 2.8%-3.8%), and the prevalence of those who required help or had difficulty was 11.7% (95% CI, 10.9%-12.6%). Completely homebound individuals were more likely to be older (83.2 vs 74.3 years, P < .001), female (67.9% vs 53.4%, P < .006), and of nonwhite race (34.1% vs 17.6%, P < .001) and have less education and income than nonhomebound individuals. They also had more chronic conditions (4.9 vs 2.5) and were more likely to have been hospitalized in the last 12 months (52.1% vs 16.2%) (P < .001 for both). Only 11.9% of completely homebound individuals reported receiving primary care services at home.

CONCLUSIONS AND RELEVANCE

In total, 5.6% of the elderly, community-dwelling Medicare population (approximately 2 million people) were completely or mostly homebound in 2011. Our findings can inform improvements in clinical and social services for these individuals.

Determinants of psychological resistance and recovery among women exposed to assaultive trauma

INTRODUCTION

Women exposed to potentially traumatic events (PTEs) are at high risk for developing psychiatric disorders, including posttraumatic stress disorder (PTSD), general anxiety disorder (GAD), major depressive disorder (MDD), and substance-related disorders. However, this risk is not universal. Most women are resistant (i.e., remain asymptomatic), or recover following a brief symptomatic period. This study examined the psychological factors associated with resistant and recovered outcomes in a sample of high-risk women exposed to assault-related PTEs.

METHOD

One hundred and fifty-nine women completed the Life Events Checklist and were administered the Structured Clinical Interview for DSM-IV Axis I Disorders. This resulted in three groups: (1) no diagnosis (no past or current psychiatric disorder diagnosis; n = 56), (2) past diagnosis (a past psychiatric disorder diagnosis, but none currently; n = 31), and (3) current diagnosis (a current diagnosis of one or more psychiatric disorders; n = 72). Groups were compared on sociodemographics, PTE exposure, psychopathology, health-related quality of life (HRQOL), and psychological resilience-related factors.

RESULTS

The majority of respondents (79%) did not develop chronic PTSD following assault exposure, and the most common psychiatric outcome was MDD (30%). High endorsement of mastery and social support were associated with the no diagnosis group; and greater reports of mastery and posttraumatic growth were associated with recovery from a past psychiatric disorder. Furthermore, both resilient groups (i.e., no diagnosis and past diagnosis) scored higher on HRQOL measures compared with the current diagnosis group (P < 0.001).

CONCLUSION

Psychological resilience has ramifications to health and well-being, and identifying these factors has potential to inform preventive strategies and treatment interventions for assault exposed women.

Financial strain is associated with increased oxidative stress levels: the Women's Health and Aging Studies

Elevated oxidative stress levels may be one mechanism contributing to poor health outcomes. Financial strain and oxidative stress are each predictors of morbidity and mortality, but little research has investigated their relationship. Community-dwelling older adults (n = 728) from the Women's Health and Aging Studies I and II were included in this cross-sectional analysis. Financial strain was ascertained as an ordinal response to: "At the end of the month, do you have more than enough money left over, just enough, or not enough?" Oxidative stress was measured using serum protein carbonyl concentrations. Linear regression was used to quantify the relationship between financial strain and oxidative stress. Participants who reported high financial strain exhibited 13.4% higher protein carbonyl concentrations compared to individuals who reported low financial strain (p = 0.002). High financial strain may be associated with increased oxidative stress, suggesting that oxidative stress could mediate associations between financial strain and poor health.

The association of neighborhood characteristics with obesity and metabolic conditions in older women

OBJECTIVE

Previous studies exploring the relationship of neighborhood characteristics with metabolic conditions have focused on middle-aged adults but none have comprehensively investigated associations in older adults, a potentially vulnerable population. The aim was to explore the relationship of neighborhood characteristics with metabolic conditions in older women.

DESIGN

Cross-sectional analysis.

SETTING/PARTICIPANTS

We studied 384 women aged 70-79 years, representing the two-thirds least disabled women in the community, enrolled in the Women's Health and Aging Study II at baseline. Neighborhood scores were calculated from census-derived data on median household income, median house value, percent earning interest income, percent completing high school, percent completing college, and percent with managerial or executive occupation. Participants were categorized by quartile of neighborhood score with a higher quartile representing relative neighborhood advantage. Logistic regression models were created to assess the association of neighborhood quartiles to outcomes, adjusting for key covariates.

MEASUREMENTS

Primary outcomes included metabolic conditions: obesity, diabetes, hypertension, and hyperlipidemia. Secondary outcomes included BMI, HbA1c, blood pressure and lipids.

RESULTS

Higher neighborhood quartile score was associated with a lower prevalence of obesity (highest quartile=13.5% versus lowest quartile=36.5%; p<0.001 for trend). A lower prevalence of diabetes was also observed in highest (6.3%) versus lowest (14.4%) neighborhood quartiles, but was not significantly different (p= 0.24 for trend). Highest versus lowest neighborhood quartile was associated with lower HbA1c (-0.31%, p=0.02) in unadjusted models. Women in the highest versus lowest neighborhood quartile had lower BMI (-2.01 kg/m2, p=0.001) and higher HDL-cholesterol (+6.09 mg/dL, p=0.01) after accounting for age, race, inflammation, and smoking.

CONCLUSION

Worse neighborhood characteristics are associated with adiposity, hyperglycemia, and low HDL. Further longitudinal studies are needed and can inform future interventions to improve metabolic status in older adults.

Preliminary data from community aging in place, advancing better living for elders, a patient-directed, team-based intervention to improve physical function and decrease nursing home utilization: the first 100 individuals to complete a centers for medicare and medicaid services innovation project

Current medical models frequently overlook functional limitations and the home environment even though they partially determine healthcare usage and quality of life. The Centers for Medicare and Medicaid Services (CMS) Innovation Center funds projects that have potential to affect the “triple aim,” a framework for decreasing costs while improving health and quality of life. This article presents preliminary data from Community Aging in Place, Advancing Better Living for Elders (CAPABLE), a model funded by the CMS Innovation Center and designed to overcome the functional and home environmental barriers of older adults. CAPABLE is a patient‐directed, team‐based intervention comprising an occupational therapist, a registered nurse, and a handyman to decrease hospitalization and nursing home usage of community‐dwelling older adults with functional limitations who are dually eligible for Medicare and Medicaid. Activity of daily living limitations improved in 79% of the first 100 people who completed the intervention. Preliminary findings of this novel intervention may have implications for other older adults with functional limitations.

Older adults' favorite activities are resoundingly active: findings from the NHATS study

Activity is associated with health among older adults yet older adults' favorite activities have rarely been investigated. We analyzed the community dwelling, cognitively-intact sample of NHATS, a nationally representative sample of adults ≥ 65, who had named their favorite activities (N = 5247). Logistic regression models estimated the odds of choosing a physical activity controlling for demographics, self-rated health, and disability. For all ages, four of the top five most common favorite activities were active: walking/jogging (14%), outdoor maintenance (13%), playing sports (8.9%), and other physical activity (8.7%). These findings sustain in 65-75 year olds. Even in 80-84 year olds, 3 of the top five activities are active. These findings vary by self-rated health (OR = 0.71, p < 0.001), disability (OR = 0.72, p < 0.001) and gender (OR = 0.52, p < 0.001). Policy makers, clinicians, and urban planners can use these results in their work.

Household and neighborhood conditions partially account for associations between education and physical capacity in the National Health and Aging Trends Study

Socioeconomic resources, such as education, prevent disability but are not readily modifiable. We tested the hypothesis that household and neighborhood conditions, which may be modifiable, partially account for associations between education and physical capacity in a population-based sample of older adults. The National Health and Aging Trends Study measured education (<high school, high school, some college, and ≥Bachelor's), household and neighborhood conditions, using a 16-item environmental checklist and a 3-item social cohesion scale, and physical capacity with the Short Physical Performance Battery (SPPB), grip strength and peak expiratory flow. Structural equation models were used to decompose total educational effects into direct effects and indirect effects via household and neighborhood conditions, using sample weights and adjusting for age, sex, race/ethnicity, marital status, household size, BMI, self-reported health, and number of medical conditions in 6874 community-dwelling participants. Education was directly associated with SPPB scores (β = 0.055, p < 0.05) and peak flow (β = 0.095, p < 0.05), but not grip strength. Also, indirect effects were found for household disorder with SPPB scores (β = 0.013, p < 0.05), grip strength (β = 0.007, p < 0.05), and peak flow (β = 0.010, p < 0.05). Indirect effects were also found for street disorder with SPPB scores (β = 0.012, p < 0.05). Indirect effects of household and neighborhood conditions accounted for approximately 35%, 27% and 14% of the total association between education and SPPB scores, grip strength level, and peak expiratory flow level, respectively. Household disorder and street disorder partially accounted for educational disparities in physical capacity. However, educational disparities in SPPB scores and peak expiratory flow persisted after accounting for household and neighborhood conditions and chronic conditions, suggesting additional pathways. Interventions and policies aiming to support aging in place should consider addressing household-level and street-level disorder.

Factors mediating the effects of a depression intervention on functional disability in older African Americans

OBJECTIVES

To determine factors mediating the effects of a depression intervention for older African Americans on functional disability and, secondarily, whether functional improvements mediate intervention effects on depressive symptoms.

DESIGN

Structural equation modeling to examine mediators in a secondary analysis of a randomized trial with 4-month follow-up.

SETTING

Philadelphia region.

PARTICIPANTS

Community-dwelling African Americans (≥55) with depressive symptoms living in an urban area (N = 208).

INTERVENTION

Up to 10 one-hour sessions over 4 months conducted by licensed social workers who provided care management, referrals and linkages, stress reduction techniques, depression knowledge and symptom recognition, and behavioral activation techniques.

MEASUREMENTS

Main outcome was self-reported functional difficulty level for 18 basic activities. Mediators included depression severity (Patient Health Questionnaire), depression knowledge and symptom recognition, behavioral activation, and anxiety.

RESULTS

At 4 months, the intervention had positive effects on functional difficulty and all mediators (P < .001). Separate structural equation models indicated that two factors (reduced depressive symptoms (23.5% mediated) and improved depression knowledge and symptom recognition (52.9% mediated)) significantly mediated the intervention's effect on functional disability. Enhancing behavioral activation and decreasing anxiety were not found to mediate improvements in functional disability. The two significant mediators jointly explained 62.5% of the intervention's total effect on functional disability. Functional improvement was not found to mediate the intervention's effect on depressive symptoms.

CONCLUSION

This multicomponent depression intervention for African Americans has an effect on functional disability that is driven primarily by enhancing symptom recognition and decreasing depressive symptoms. Reduction of functional difficulties did not account for improvements in depressive symptoms. Nonpharmacological treatments for depressive symptoms that enhance symptom recognition in older African Americans can also reduce their functional difficulties with daily living activities.

Beat the Blues decreases depression in financially strained older African-American adults

OBJECTIVES

Financial strain, defined as inadequate income to cover basic needs, is related to depression in minority populations. It is unclear whether interventions can improve depression in those reporting financial strain.

DESIGN

Randomized controlled trial.

SETTING

Philadelphia senior center.

PARTICIPANTS

A total of 208 African-American adults 55 years of age and older with mild to severe depressive symptoms.

MEASUREMENTS

Beat the Blues (BTB) depression intervention, which includes care management, referral/linkage, stress reduction, depression education, and behavioral activation. Measurements included responses to the Patient Health Questionnaire-9, financial strain, and age.

RESULTS

Although financial strain was related to depressive symptoms at baseline, participants receiving BTB at all levels of financial strain showed reduced depressive symptoms compared with a waitlist control group at 4 months. BTB participants reporting financial strain had a mean (standard deviation) decrease of 6.4 (0.85) points on the Patient Health Questionnaire-9, reflecting a clinically meaningful improvement.

CONCLUSIONS

This nonpharmacologic intervention reduced depressive symptoms in both African-American subjects with and without financial strain. However, screening for and helping people manage financial strain may boost the magnitude of intervention benefit for those with financial strain and should be explored as part of depression care.

CAPABLE trial: a randomized controlled trial of nurse, occupational therapist and handyman to reduce disability among older adults: rationale and design

BACKGROUND

As the population ages, it is increasingly important to test new models of care that improve life quality and decrease health costs. This paper presents the rationale and design for a randomized clinical trial of a novel interdisciplinary program to reduce disability among low income older adults based on a previous pilot trial of the same design showing strong effect.

METHODS

The CAPABLE (Community Aging in Place, Advancing Better Living for Elders) trial is a randomized controlled trial in which low income older adults with self-care disability are assigned to one of two groups: an interdisciplinary team of a nurse, occupational therapist, and handyman to address both personal and environmental risk factors for disability based on participants' functional goals, or an attention control of sedentary activities of choice. Both groups receive up to 10 home visits over 4 months.

OUTCOMES

The primary outcome is decreased disability in self-care (ADL). Secondary outcomes are sustained decrease in self care disability as well as improvement in instrumental ADLS, strength, balance, walking speed, and health care utilization. Careful cost tracking and analysis using intervention data and claims data will enable direct measurement of the cost impact of the CAPABLE approach. CAPABLE has the potential to leverage current health care spending in Medicaid waivers, Accountable Care Organizations and other capitated systems to save the health care system costs as well as improving low income older adults' ability to age at home with improved life quality.

Assistive devices in context: cross-sectional association between challenges in the home environment and use of assistive devices for mobility

PURPOSE

A primary goal for aging policy is to optimize independence in later life. We estimate the cross-sectional association between physical and social challenge in the home environment and use of assistive devices (AD) for mobility in the home, controlling for lower extremity physical performance (short physical performance battery [SPPB]) and other factors.

DESIGN AND METHODS

Data are from the Women's Health and Aging Study I, a prospective study of the factors related to physical disability in a sample of moderately to severely disabled older women. We describe these associations in the baseline sample overall and also within subsets who do and do not have both a baseline and a 3-year follow-up observation.

RESULTS

On average, physical challenge in the home environment is inversely associated with level of AD use (p < .05) in the overall sample, independent of SPPB, living alone, and other factors. We do not find a significant (p < .05) association between social challenge and the level of AD use in the overall sample. Findings by follow-up responder status were similar (with minor variability).

IMPLICATIONS

Future cohorts who are better educated and more receptive to technology may confront challenges in the home environment that limit their ability to age in place. Our findings suggest that the physical challenges of the home are significantly related to AD use. Future analyses that explore the mechanisms of the home environment as a source of challenges to independent functioning could help in the design of future interventions for these cohorts as they age.

Education, income and disability in African Americans

OBJECTIVE

To determine whether the association between SES and disability vary by age in African Americans.

METHODS

Logistic regression models were conducted to estimate the association between SES and disability by age group in 395 African Americans participating in the Carolina African American Twin Study of Aging. Disability was defined as difficulty in performing at least one of seven basic activities of daily living. Education and family income were used as measures of SES. Age was categorized as individuals aged < 49 years and aged > or = 50 years.

RESULTS

After adjusting for demographic and health-related characteristics among older adults, a higher odds of disability was associated with no post-secondary education (OR = 3.09, 95% CI: 1.24-7.71), and with low-income (OR = 2.74, 95% CI: 1.17-6.43) compared to more educated or affluent people, respectively. No association between SES and disability was observed in young adults. When considering the combined effect of no post-secondary education and low-income on disability, older adults with no post-secondary education had a greater odds of being disabled (OR = 2.63, 95% CI: 1.03-6.73) relative to those with a post-secondary education controlling for covariates.

CONCLUSIONS

The findings demonstrate the advantage of disentangling the confounding of race and SES as an initial step to understanding the relationship among age, SES and disability in African Americans.

Development of an institutional review board preapproval process for Doctor of Nursing Practice students: process and outcome

As Doctor of Nursing Practice (DNP) programs proliferate, effective collaboration with institutional review boards (IRBs) is important to protect human subjects. It is particularly important that faculty and students recognize which DNP students' projects should be considered as "human subjects research" or "quality improvement." The former require IRB review, whereas the latter may be eligible for expedited review or may be considered exempt. We report outcomes following implementation of a combination of didactic training, one-to-one consultation, and a decision support protocol to improve preparation for and collaboration with the IRB at a large university. In the first year of using this protocol, 53% of projects were deemed human subjects research and received IRB review. The other 47% were deemed quality improvement projects and did not require IRB review. We offer our experience as an approach for teaching students how to protect the subjects included in their quality improvement activities.

Racial discrimination is associated with a measure of red blood cell oxidative stress: a potential pathway for racial health disparities

BACKGROUND

There are racial health disparities in many conditions for which oxidative stress is hypothesized to be a precursor. These include cardiovascular disease, diabetes, and premature aging. Small clinical studies suggest that psychological stress may increase oxidative stress. However, confirmation of this association in epidemiological studies has been limited by homogenous populations and unmeasured potential confounders.

PURPOSE

We tested the cross-sectional association between self-reported racial discrimination and red blood cell (RBC) oxidative stress in a biracial, socioeconomically heterogeneous population with well-measured confounders.

METHODS

We performed a cross-sectional analysis of a consecutive series of 629 participants enrolled in the Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS) study. Conducted by the National Institute on Aging Intramural Research Program, HANDLS is a prospective epidemiological study of a socioeconomically diverse cohort of 3,721 Whites and African Americans aged 30-64 years. Racial discrimination was based on self-report. RBC oxidative stress was measured by fluorescent heme degradation products. Potential confounders were age, smoking status, obesity, and C-reactive protein.

RESULTS

Participants had a mean age of 49 years (SD = 9.27). In multivariable linear regression models, racial discrimination was significantly associated with RBC oxidative stress (Beta = 0.55, P < 0.05) after adjustment for age, smoking, C-reactive protein level, and obesity. When stratified by race, discrimination was not associated with RBC oxidative stress in Whites but was associated significantly for African Americans (Beta = 0.36, P < 0.05).

CONCLUSIONS

These findings suggest that there may be identifiable cellular pathways by which racial discrimination amplifies cardiovascular and other age-related disease risks.

Nursing strategies for promoting and maintaining function among community-living older adults: the CAPABLE intervention

Although many programs aim to help older adults age in place, few target both the home environment and individual physical function. We present an interprofessional intervention called CAPABLE-Community Aging in Place: Advancing Better Living for Elders. CAPABLE's innovative approach incorporates a nurse, occupational therapist (OT), and handyman to address both individual and environmental factors that contribute to disability. The nurse component of CAPABLE addresses key barriers to functional independence such as pain, depression, strength and balance, medication management, and poor communication with the primary care provider. This article focuses primarily on the nursing aspect of the intervention and how it interrelates with the content and processes of the OT and handyman.

Incorporating salivary biomarkers into nursing research: an overview and review of best practices

Analytes and biomarkers present in saliva may provide insight into individual differences in environmental chemical exposures, variation in reproductive hormones, therapeutic and illegal substance use, changes in stress-related physiology, and the immunologic footprints of infectious disease. The wealth of information provided by salivary analytes has the potential to enrich biobehavioral nursing research by enabling researchers to measure these individual differences in the clinic as well as in patients' and participants' everyday social worlds. In this article, the authors provide a roadmap for researchers new to this area who would like to learn more about integrating salivary biospecimens into the next generation of health research. In addition, the authors highlight best practices and strategies to avoid common pitfalls for researchers already engaged in this field.

Patterns of 12-year change in physical activity levels in community-dwelling older women: can modest levels of physical activity help older women live longer?

Few studies have addressed changes in physical activity participation over time among the elderly. The authors hypothesized that there were distinct trajectories of physical activity level over time and identifiable predictors of such trajectories, as well as that the maintenance of regular physical activity, even below recommended levels, was associated with lower mortality risk. Using longitudinal data (1994-2009) from 433 initially high-functioning older women aged 70-79 years at baseline, a joint latent class and survival mixture model identified 4 activity trajectory classes: always active (16.6%), fast declining (19.2%), stable moderate (32.3%), and always sedentary (31.9%). Obesity, coronary artery disease, chronic obstructive pulmonary disease, depressive symptoms, low self-efficacy, mobility disability, and low energy were associated with sedentary behavior and/or a fast decline in activity. Women in the fast declining and always sedentary classes had hazard ratios for death of 2.34 (95% confidence interval: 1.20, 4.59) and 3.34 (95% confidence interval: 1.72, 6.47), respectively, compared with the always active class; no mortality difference was found between the stable moderate and always active groups (hazard ratio = 1.24, 95% confidence interval: 0.63, 2.47). Our findings suggest that physical activity does not have to be vigorous to be beneficial and that the gain may be the greatest among women who reported the lowest levels of activity.

Financial Strain Is Associated with Malnutrition Risk in Community-Dwelling Older Women

This study examined the relationship between financial strain, or difficulty acquiring necessities, and malnutrition risk in a community dwelling sample of frail and nonfrail women aged 70-79 in the Women's Health and Aging Study (n = 679). Malnutrition risk was measured with a modified version of the Mini-Nutritional Assessment Short Form (MNA-SF) and defined as a score <11, financial strain was measured by (1) sufficiency of money on a monthly basis and (2) adequacy of income for food, and income was measured by ordinal categories. Mean (SD) modified MNA-SF score was 12.2 (1.80), and 14.7% of women had malnutrition risk. Women who usually did not have enough money to make ends meet had more than four-fold increased odds of malnutrition risk (OR = 4.54; 95% CI: 2.26, 9.14) compared to their counterparts who had some money left over each month. This was only slightly attenuated after control for income and education, (OR = 4.08; 95% CI: 1.95, 8.52) remaining robust. These results show an association between financial strain and malnutrition risk, independent of income, in older women. Self-reported financial strain may be preferable to income as a screener for malnutrition risk in older adults in clinical and research settings.

Community aging in place, advancing better living for elders: a bio-behavioral-environmental intervention to improve function and health-related quality of life in disabled older adults

OBJECTIVES

To determine effect size and acceptability of a multicomponent behavior and home repair intervention for low-income disabled older adults.

DESIGN

Prospective randomized controlled pilot trial.

SETTING

Participants' homes.

PARTICIPANTS

Forty low-income older adults with difficulties in one or more activities of daily living (ADLs) or two or more instrumental activities of daily living (IADLs).

INTERVENTION

The Community Aging in Place, Advancing Better Living for Elders (CAPABLE), coordinated occupational therapy, nursing, and handyman visits, was compared with attention-control visits. The intervention consisted of up to six visits with an occupational therapist, up to four visits with a nurse, and an average of $1,300 in handyman repairs and modifications. Each intervention participant received all components of the intervention clinically individualized to risk profile and goals. Each attention-control participant received the same number of visits as the intervention participants, involving sedentary activities of their choice.

MEASUREMENT

PRIMARY OUTCOME

difficulty in performing ADLs and IADLs.

SECONDARY OUTCOMES

health-related quality of life and falls efficacy.

RESULTS

Thirty-five of 40 adults (87%) completed the 6-month trial, and 93% and 100% of the control and intervention group, respectively, stated that the study benefited them. The intervention group improved on all outcomes. When comparing mean change in the intervention group with mean change in the control group from baseline to follow-up, the CAPABLE intervention had effect sizes of 0.63 for reducing difficulty in ADLs, 0.62 for reducing difficulty in IADLs, 0.89 for quality of life, and 0.55 for falls efficacy.

CONCLUSION

The CAPABLE intervention was acceptable to participants and feasible to provide and showed promising results, suggesting that this multicomponent intervention to reduce disability should be evaluated in a larger trial.

Community Outreach and Cardiovascular Health (COACH) Trial: a randomized, controlled trial of nurse practitioner/community health worker cardiovascular disease risk reduction in urban community health centers

BACKGROUND

Despite well-publicized guidelines on the appropriate management of cardiovascular disease and type 2 diabetes, the implementation of risk-reducing practices remains poor. This report describes the results of a randomized, controlled clinical trial evaluating the effectiveness of a comprehensive program of cardiovascular disease risk reduction delivered by nurse practitioner /community health worker (NP/CHW) teams versus enhanced usual care (EUC) to improve lipids, blood pressure, glycated hemoglobin (HbA1c), and patient perceptions of the quality of their chronic illness care in patients in urban community health centers.

METHODS AND RESULTS

A total of 525 patients with documented cardiovascular disease, type 2 diabetes, hypercholesterolemia, or hypertension and levels of LDL cholesterol, blood pressure, or HbA1c that exceeded goals established by national guidelines were randomly assigned to NP/CHW (n=261) or EUC (n=264) groups. The NP/CHW intervention included aggressive pharmacological management and tailored educational and behavioral counseling for lifestyle modification and problem solving to address barriers to adherence and control. Compared with EUC, patients in the NP/CHW group had significantly greater 12-month improvement in total cholesterol (difference, 19.7 mg/dL), LDL cholesterol (difference,15.9 mg/dL), triglycerides (difference, 16.3 mg/dL), systolic blood pressure (difference, 6.2 mm Hg), diastolic blood pressure (difference, 3.1 mm Hg), HbA1c (difference, 0.5%), and perceptions of the quality of their chronic illness care (difference, 1.2 points).

CONCLUSIONS

An intervention delivered by an NP/CHW team using individualized treatment regimens based on treat-to-target algorithms can be an effective approach to improve risk factor status and perceptions of chronic illness care in high-risk patients.

Correlates of mobility limitation in African Americans

BACKGROUND

This study identified demographic and health-related characteristics that were related to mobility limitation in a sample of community-dwelling African Americans.

METHODS

The sample consisted of 602 community-dwelling African-American men and women ages 48-92 years at study inception. Participants who reported being limited "a lot" or "a little" in climbing one flight of stairs or walking several blocks were considered to have mobility limitation. Logistic regression was conducted to estimate the independent effect of each demographic and health-related characteristic on odds of mobility limitation.

RESULTS

African Americans who reported two or more medical conditions had higher odds of mobility limitation (women: odds ratio = 3.52; 95% confidence interval: 1.89-6.53 and men: odds ratio = 2.53; 95% confidence interval: 1.10-5.85) than those who reported one or fewer medical conditions. African Americans with major depressive symptoms had higher odds of mobility limitation (women: odds ratio = 2.98; 95% confidence interval: 1.55-5.71 and men: odds ratio = 3.19; 95% confidence interval: 1.33-7.65) than those without major depressive symptoms.

CONCLUSIONS

These results highlight the importance of creating interventions particularly focused on chronic disease prevention and management for African American men and women during midlife to attempt to delay the onset or impede the progression of mobility problems that will likely become exacerbated in late life and severely affect the quality of life.

Examining mindfulness-based stress reduction: perceptions from minority older adults residing in a low-income housing facility

Background

Mindfulness-based stress reduction (MBSR) programs are becoming increasingly common, but have not been studied in low income minority older populations. We sought to understand which parts of MBSR were most important to practicing MBSR members of this population, and to understand whether they apply their training to daily challenges.

Methods

We conducted three focus groups with 13 current members of an MBSR program. Participants were African American women over the age of 60 in a low-income housing residence. We tape recorded each session and subsequently used inductive content analysis to identify primary themes.

Results and discussion

Analysis of the focus group responses revealed three primary themes stress management, applying mindfulness, and the social support of the group meditation. The stressors they cited using MBSR with included growing older with physical pain, medical tests, financial strain, and having grandchildren with significant mental, physical, financial or legal hardships. We found that participants particularly used their MBSR training for coping with medical procedures, and managing both depression and anger.

Conclusion

A reflective stationary intervention delivered in-residence could be an ideal mechanism to decrease stress in low-income older adult's lives and improve their health.

COACH trial: a randomized controlled trial of nurse practitioner/community health worker cardiovascular disease risk reduction in urban community health centers: rationale and design

BACKGROUND

Despite well-publicized guidelines on the appropriate management of cardiovascular disease (CVD) and type 2 diabetes, implementation of risk-reducing practices remains poor. This paper describes the rationale and design of a randomized controlled clinical trial evaluating the effectiveness of a comprehensive program of CVD risk reduction delivered by nurse practitioner (NP)/community health worker (CHW) teams versus enhanced usual care in improving the proportion of patients in urban community health centers who achieve goal levels recommended by national guidelines for lipids, blood pressure, HbA1c and prescription of appropriate medications.

METHODS

The COACH (Community Outreach and Cardiovascular Health) trial is a randomized controlled trial in which patients at federally-qualified community health centers were randomly assigned to one of two groups: comprehensive intensive management of CVD risk factors for one year by a NP/CHW team or an enhanced usual care control group.

RESULTS

A total of 3899 patients were assessed for eligibility and 525 were randomized. Groups were comparable at baseline on sociodemographic and clinical characteristics with the exception of statistically significant differences in total cholesterol and hemoglobin A1c.

CONCLUSIONS

This study is a novel amalgam of multilevel interdisciplinary strategies to translate highly efficacious therapies to low-income federally-funded health centers that care for patients who carry a disproportionate burden of CVD, type 2 diabetes and uncontrolled CVD risk factors. The impact of such a community clinic-based intervention is potentially enormous.
