RESUMEN
Importance: The effect of intensive blood pressure lowering on brain health remains uncertain. Objective: To evaluate the association of intensive blood pressure treatment with cerebral white matter lesion and brain volumes. Design, Setting, and Participants: A substudy of a multicenter randomized clinical trial of hypertensive adults 50 years or older without a history of diabetes or stroke at 27 sites in the United States. Randomization began on November 8, 2010. The overall trial was stopped early because of benefit for its primary outcome (a composite of cardiovascular events) and all-cause mortality on August 20, 2015. Brain magnetic resonance imaging (MRI) was performed on a subset of participants at baseline (n = 670) and at 4 years of follow-up (n = 449); final follow-up date was July 1, 2016. Interventions: Participants were randomized to a systolic blood pressure (SBP) goal of either less than 120 mm Hg (intensive treatment, n = 355) or less than 140 mm Hg (standard treatment, n = 315). Main Outcomes and Measures: The primary outcome was change in total white matter lesion volume from baseline. Change in total brain volume was a secondary outcome. Results: Among 670 recruited patients who had baseline MRI (mean age, 67.3 [SD, 8.2] years; 40.4% women), 449 (67.0%) completed the follow-up MRI at a median of 3.97 years after randomization, after a median intervention period of 3.40 years. In the intensive treatment group, based on a robust linear mixed model, mean white matter lesion volume increased from 4.57 to 5.49 cm3 (difference, 0.92 cm3 [95% CI, 0.69 to 1.14]) vs an increase from 4.40 to 5.85 cm3 (difference, 1.45 cm3 [95% CI, 1.21 to 1.70]) in the standard treatment group (between-group difference in change, -0.54 cm3 [95% CI, -0.87 to -0.20]). Mean total brain volume decreased from 1134.5 to 1104.0 cm3 (difference, -30.6 cm3 [95% CI, -32.3 to -28.8]) in the intensive treatment group vs a decrease from 1134.0 to 1107.1 cm3 (difference, -26.9 cm3 [95% CI, 24.8 to 28.8]) in the standard treatment group (between-group difference in change, -3.7 cm3 [95% CI, -6.3 to -1.1]). Conclusions and Relevance: Among hypertensive adults, targeting an SBP of less than 120 mm Hg, compared with less than 140 mm Hg, was significantly associated with a smaller increase in cerebral white matter lesion volume and a greater decrease in total brain volume, although the differences were small. Trial Registration: ClinicalTrials.gov Identifier: NCT01206062.

Importance: There are currently no proven treatments to reduce the risk of mild cognitive impairment and dementia. Objective: To evaluate the effect of intensive blood pressure control on risk of dementia. Design, Setting, and Participants: Randomized clinical trial conducted at 102 sites in the United States and Puerto Rico among adults aged 50 years or older with hypertension but without diabetes or history of stroke. Randomization began on November 8, 2010. The trial was stopped early for benefit on its primary outcome (a composite of cardiovascular events) and all-cause mortality on August 20, 2015. The final date for follow-up of cognitive outcomes was July 22, 2018. Interventions: Participants were randomized to a systolic blood pressure goal of either less than 120 mm Hg (intensive treatment group; n = 4678) or less than 140 mm Hg (standard treatment group; n = 4683). Main Outcomes and Measures: The primary cognitive outcome was occurrence of adjudicated probable dementia. Secondary cognitive outcomes included adjudicated mild cognitive impairment and a composite outcome of mild cognitive impairment or probable dementia. Results: Among 9361 randomized participants (mean age, 67.9 years; 3332 women [35.6%]), 8563 (91.5%) completed at least 1 follow-up cognitive assessment. The median intervention period was 3.34 years. During a total median follow-up of 5.11 years, adjudicated probable dementia occurred in 149 participants in the intensive treatment group vs 176 in the standard treatment group (7.2 vs 8.6 cases per 1000 person-years; hazard ratio [HR], 0.83; 95% CI, 0.67-1.04). Intensive BP control significantly reduced the risk of mild cognitive impairment (14.6 vs 18.3 cases per 1000 person-years; HR, 0.81; 95% CI, 0.69-0.95) and the combined rate of mild cognitive impairment or probable dementia (20.2 vs 24.1 cases per 1000 person-years; HR, 0.85; 95% CI, 0.74-0.97). Conclusions and Relevance: Among ambulatory adults with hypertension, treating to a systolic blood pressure goal of less than 120 mm Hg compared with a goal of less than 140 mm Hg did not result in a significant reduction in the risk of probable dementia. Because of early study termination and fewer than expected cases of dementia, the study may have been underpowered for this end point. Trial Registration: ClinicalTrials.gov Identifier: NCT01206062.

BACKGROUND: The responsibility of care for Veterans and Service Members (V/SMs) with traumatic brain injury (TBI) often defaults to informal family caregivers. Caregiving demands considerable knowledge, skill, and support to facilitate the health and well-being of V/SMs and themselves. Persistent and common TBI caregiver issues include strain, depression, and anxiety. While evidence-based, brief interventions have been developed and implemented for family caregivers in Veteran neurodegenerative populations, few interventions have been developed, adapted, or tested to support the unique needs of caregivers of V/SMs with TBI. OBJECTIVE: This study will adapt and test an evidence-based, personalized, 6-session telehealth caregiver intervention, "Resources for Enhancing All Caregivers' Health" (REACH), to meet the unique needs of caregivers of V/SMs with TBI. If successful, a community-based participatory research team will develop an implementation plan to roll out REACH TBI across the national Veterans Affairs Polytrauma System of Care. METHODS: This mixed methods, crossover waitlist control clinical trial will use a Type 1 Hybrid Effectiveness-Implementation approach to adapt and then test the effects of REACH TBI on key TBI caregiver outcomes. RESULTS: This study was funded by the Department of Defense in September 2023. Participant enrollment and data collection will begin in 2024. CONCLUSIONS: If effective, REACH TBI will be the first evidence-based intervention for caregivers of V/SMs with TBI that can be scaled to implement across the Veterans Affairs Polytrauma System of Care and fill a notable gap in clinical services.

Spouses of returning Iraq (Operation Iraqi Freedom, OIF) and Afghanistan (Operation Enduring Freedom, OEF) military service members report increased depression and anxiety post deployment as they work to reintegrate the family and service member. Reconnecting the family, renegotiating roles that have shifted, reestablishing communication patterns, and dealing with mental health concerns are all tasks that spouses must undertake as part of reintegration. We tested telephone support groups focusing on helping spouses with these basic reintegration tasks. Year-long telephone support groups focused on education, skills building (communication skills, problem solving training, cognitive behavioral techniques, stress management), and support. Spouse depression and anxiety were decreased and perceived social support was increased during the course of the study. In subgroup analyses, spouses with husbands whose injuries caused care difficulties had a positive response to the intervention. However, they were more likely to be depressed, be anxious, and have less social support compared to participants who had husbands who had no injury or whose injury did not cause care difficulty. Study findings suggest that this well-established, high-access intervention can help improve quality of life for military spouses who are struggling with reintegration of the service member and family.

The purpose of this study was to determine if telephone support groups for dementia caregivers have an effect on bother with patient behaviours, burden, depression, and general well-being. The randomized controlled trial compared telephone support groups (15 groups of 5 or 6 caregivers) with control groups (print materials). Groups met 14 times over 1 year. The 1-hour sessions included content on education, coping skills, and support. Data were collected at baseline and at 6 and 12 months. The sample comprised 154 caregivers, 77 per arm, providing care to veterans with dementia or a veteran caregiver. Bother was found to differ significantly at baseline. There were no significant treatment effect differences between study arms. Participants anecdotally reported improvement. It was concluded that telephone support groups are an efficient way to interact with caregivers. Further research should test different models of care. Interventions that are targeted to specific needs or occur frequently may provide better support for caregivers of individuals with a worsening condition.

BACKGROUND: Parents often provide care to adult children veterans with polytrauma, traumatic brain injury, and/or post-traumatic stress disorder. OBJECTIVE: This two-arm randomized clinical trial compared interventions to help parent caregivers improve their depression, anxiety, and burden and manage care by decreasing troubling and concerning behaviors. METHODS: Interventions were six one-hour structured one-on-one behavioral sessions (REACH) or six 30-minute prerecorded online educational webinars. Both focused on knowledge, strategies for care, and coping, but REACH sessions were targeted, interactive, and skills-based. Quantitative and qualitative data were collected by telephone. Quantitative analyses included chi-squared test or independent samples t-test and repeated measures mixed linear modeling, with theme development for qualitative data. RESULTS: There were 163 parent caregivers, mostly mothers. During six months, participants in both arms improved significantly in depression, anxiety, burden, and reported veteran troubling and concerning behaviors. REACH caregivers showed a group by time improvement in concerning behaviors. Benefits included resources, self-reflection, not feeling alone, new skills, improved self-efficacy, and helping others. Specific concerns include exclusion from military and veteran care briefings and concern for the future. CONCLUSION: The positive response to both interventions provides opportunities for organizations with varying resources to provide support for parent caregivers. Interventions need to be targeted to parents' particular concerns and needs.

Self-care improves health and well-being, yet many caregivers neglect it. During COVID-19, self-care courses for caregivers of veterans transitioned from in-person to virtual videoconferencing. The format remained the same with caregiver groups and a trainer. This observational study examined in-person and virtual caregivers' satisfaction with courses. Caregivers (1120 in-person, 962 virtual) could attend five courses before and following March 2020 transition to virtual. Evaluations (N = 1665) examined demographics, satisfaction, and utility. Characteristics were compared between in-person and virtual participants using chi-squared tests. Qualitative caregiver comments were compared. Half of the caregivers were over 60 years old; 49% had been caregivers at least 6 years. Caregivers were primarily women (91%) and spouses (75%), with more spouses virtually (p = 0.006) and more men in-person (p < 0.001). Both groups endorsed learning new information, planning to use it in caregiving and for themselves, increasing knowledge and skills, and having needs met. Caregiver comments revealed six types of benefits: new information, information review, positive effects, interaction, plans to act, and instructor qualities. Caregivers in virtual groups more often mentioned learning more information, being reminded of information, and planning to take further action; in-person caregivers more often mentioned interaction as a benefit. Caregivers were satisfied with and found benefit from in-person and virtual self-care courses. Although in-person courses allow for more social connection with others, virtual courses offer decreased travel costs for instructors and increased convenience and access for caregivers.
RESUMEN
BACKGROUND: Estimating effectiveness of clinical interventions depends on detecting differences between the responses of intervention and control groups. The outcome, intervention, and moderating factors all may influence the between group change. The absence of a clinically or statistically meaningful difference may also result from control group improvement due to nonspecific factors such as participants' perception of attention, positive regard, expectations, desire to please, and therapeutic alliance with the care provider. PURPOSE: We examined perceived benefit and sources of benefit for control caregivers who participated in the CONNECT randomized controlled trial of a dementia caregiving intervention. METHODS: After the final scheduled data collection in CONNECT, control group participants were asked whether they believed they benefited from study participation. Those who reported benefit were asked to describe the benefit received. Data were analyzed qualitatively. RESULTS: Of 60 available control caregivers, 82% reported a perceived benefit from study participation in five areas: getting information about dementia and caregiving; having someone to talk to and feeling supported; receiving understanding and validation of feelings; knowledge that others were in similar situations; and perceived appreciation of own abilities. Control caregivers who reported benefit were less burdened and depressed and spent less time on duty at baseline than those who did not report benefit. From caregivers' responses, we have identified the assessment battery, both content and time spent in data collection, as a possible mechanism of action for benefit. LIMITATIONS: Study limitations include the better baseline characteristics of the control caregivers who reported benefit, the sample size of benefit control caregivers, the possibility of perceptions of benefit being a function of social desirability, and the lack of a similar question about benefit being asked of intervention caregivers. CONCLUSIONS: These findings suggest that the outcome assessment questionnaires used in this and similar trials may be an intervention of sorts for caregiver participants in the control group. Caregivers who are less distressed may benefit more from the attention provided during assessment. These findings underscore the importance of asking caregivers how they are doing. For researchers, there is a need to develop innovative ways to assess outcomes to avoid unintended benefit of assessments.

The goal of this study was to examine the relationships between heightened anxiety, social support, and physical health in a sample of spouses of returning Iraq and Afghanistan service members. 86 spouses were recruited nationally as part of a pilot trial of a military spouse telephone support group. Participants completed measures of physical and mental health via telephone including a screening tool for generalized anxiety disorder (GAD). Scores for social support and health outcomes were compared across two groups (positive vs. negative screens for GAD) using one-way analysis of variance analysis procedures. Path analytic techniques were used to evaluate the relative effects of anxiety and perceived social support on overall health and physical health comorbidities. A total of 38 participants screened positive for GAD. Participants with probable GAD reported having less social support than those screening negative for GAD. GAD participants also reported poorer overall health and more physical health comorbidities than their GAD-negative counterparts. Path analysis indicated that heightened anxiety is associated with worse overall health and social support does not buffer this interaction. The results suggest that anxiety-related health is a critical factor to be addressed in spouses of service members.

BACKGROUND: Although there are many interventions to support caregivers, SMS text messaging has not been used widely. OBJECTIVE: In this paper, we aimed to describe development of the Department of Veterans Affairs (VA) Annie Stress Management SMS text messaging protocol for caregivers of veterans, its pilot test, and subsequent national rollout. METHODS: The stress management protocol was developed with text messages focusing on education, motivation, and stress-alleviating activities based on the Resources for Enhancing All Caregivers Health (REACH) VA caregiver intervention. This protocol was then tested in a pilot study. On the basis of the pilot study results, a national rollout of the protocol was executed and evaluated. Caregivers were referred from VA facilities nationally for the pilot and national rollout. Pilot caregivers were interviewed by telephone; national rollout caregivers were sent a web-based evaluation link at 6 months. For both evaluations, questions were scored on a Likert scale ranging from completely disagree to completely agree. For both the pilot and national rollout, quantitative data were analyzed with frequencies and means; themes were identified from open-ended qualitative responses. RESULTS: Of the 22 caregivers in the pilot study, 18 (82%) provided follow-up data. On a 5-point scale, they reported text messages had been useful in managing stress (mean score 3.8, SD 1.1), helping them take care of themselves (mean score 3.7, SD 1.3), and making them feel cared for (mean score 4.1, SD 1.7). Texts were easy to read (mean score 4.5, SD 1.2), did not come at awkward times (mean score 2.2, SD 1.4), were not confusing (mean score 1.1, SD 0.2), and did not cause problems in responding (mean score 1.9, 1.1); however, 83% (15/18) of caregivers did not want to request an activity when stressed. Consequently, the national protocol did not require caregivers to respond. In the national rollout, 22.17% (781/3522) of the eligible caregivers answered the web-based survey and reported that the messages had been useful in managing stress (mean score 4.3, SD 0.8), helping them take care of themselves (mean score 4.3, SD 0.8) and loved ones (mean score 4.2, SD 0.8), and making them feel cared for (mean score 4.5, SD 0.8). Almost two-thirds (509/778, 65.4%) of the participants tried all or most of the strategies. A total of 5 themes were identified. The messages were appreciated, helped with self-care, and made them feel less alone, looking on Annie as a friend. The caregivers reported that the messages were on target and came when they were most needed and did not want them to stop. This success has led to four additional caregiver texting protocols: bereavement, dementia behaviors and stress management, (posttraumatic stress disorder) PTSD behaviors, and taking care of you, with 7274 caregivers enrolled as of February 2022. CONCLUSIONS: Caregivers reported the messages made them feel cared for and more confident. SMS text messaging, which is incorporated into clinical settings and health care systems, may represent a low-cost way to provide useful and meaningful support to caregivers.
RESUMEN
BACKGROUND: To examine the effect of intensive blood pressure control on the occurrence of subtypes of mild cognitive impairment (MCI) and determine the risk of progression to dementia or death. METHODS: Secondary analysis of a randomized trial of community-dwelling adults (≥50 years) with hypertension. Participants were randomized to a systolic blood pressure (SBP) goal of <120 mm Hg (intensive treatment; n = 4678) or <140 mm Hg (Standard treatment; n = 4683). Outcomes included adjudicated MCI, MCI subtype (amnestic, non-amnestic, multi-domain, single domain), and probable dementia. Multistate survival models were used to examine transitions in cognitive status accounting for the competing risk of death. RESULTS: Among 9361 randomized participants (mean age, 67.9 years; 3332 women [35.6%]), 640 participants met the protocol definition for MCI, with intensive treatment reducing the risk of MCI overall (hazard ratio [HR], 0.81 [95% confidence interval {CI}, 0.69-0.94]), as previously reported. This effect was largely reflected in amnestic subtypes (HR, 0.78 [95% CI, 0.66-0.92]) and multi-domain subtypes (HR, 0.78 [95% CI, 0.65-0.93]). An adjudication of MCI, as compared with normal cognitive function, substantially increased the probability of progressing to probable dementia (5.9% [95% CI: 4.5%-7.7%] vs. 0.6% [95% CI: 0.3%-0.9%]) and to death (10.0% [95% CI: 8.3%-11.9%] vs. 2.3% [95% CI: 2.0%-2.7%]) within 2 years. CONCLUSIONS: Intensive treatment reduced the risk for amnestic and multi-domain subtypes of MCI. An adjudication of MCI was associated with increased risk of progression to dementia and death, highlighting the relevance of MCI as a primary outcome in clinical and research settings.

Although the quality of the relationship between caregivers and care recipients predicts the well-being of both people, gaps exist in understanding the interpersonal dynamics of adult caregiving. We introduce relational turbulence theory as a conceptual framework for understanding how caregivers and care recipients relate to each other. We searched for research on relational turbulence theory as well as research on the relationships of adult care partners. Then, we integrated the two bodies of work. Our review suggests initial support for the theory's three central tenets: (a) transitions, including the transition to caregiving, are key periods within relationships; (b) relational uncertainty and interdependence are relationship parameters that complicate relating during transitions; and (c) relational turbulence predicts outcomes. Recommendations for practice include (a) helping care partners focus on relationship continuity, (b) gearing clinical services toward both people, (c) educating them about relational uncertainty and interdependence, and (d) teaching them communication strategies for diminishing relational turbulence. Making care partners aware of interpersonal challenges may bolster relationship satisfaction.

INTRODUCTION: Low- and middle-income countries have rapidly increasing numbers of people with dementia, yet little evidence on family caregiving interventions. We tested the preliminary efficacy and feasibility of a family caregiving intervention in northern Vietnam. METHODS: Nine clusters comprising 60 family caregivers were randomized to a culturally adapted version of a four- to six-session, multicomponent intervention delivered in-home over 2 to 3 months, or enhanced control. Eligible caregivers were ≥18 years of age and scored ≥6 on the Zarit Burden Inventory (ZBI). RESULTS: Fifty-one caregivers (85%) completed the study. Using analysis of covariance with 3-month assessment as the outcome and baseline assessment as a covariate, intervention group caregivers had an average ZBI (primary outcome) score 1.2 standard deviation (SD) lower (P = .02) and Patient Health Questionnaire-4 (psychological distress) score 0.7 SD lower (P = .03) than controls. DISCUSSION: In the first study of its kind in Vietnam, a culturally adapted, manualized, family caregiver intervention was both efficacious and feasible.
RESUMEN
BACKGROUND: Results from the Systolic Blood Pressure Intervention Trial (SPRINT) showed that intensive control of systolic blood pressure significantly reduced the occurrence of mild cognitive impairment, but not probable dementia. We investigated the effects of intensive lowering of systolic blood pressure on specific cognitive functions in a preplanned substudy of participants from SPRINT. METHODS: SPRINT was an open-label, multicentre, randomised controlled trial undertaken at 102 sites, including academic medical centres, Veterans Affairs medical centres, hospitals, and independent clinics, in the USA and Puerto Rico. Participants were adults aged 50 years or older with systolic blood pressure higher than 130 mm Hg, but without diabetes, history of stroke, or dementia. Participants were randomly assigned (1:1) to a systolic blood pressure goal of less than 120 mm Hg (intensive treatment) versus less than 140 mm Hg (standard treatment). All major classes of antihypertensive agents were included. A subgroup of randomly assigned participants including, but not limited to, participants enrolled in an MRI substudy was then selected for a concurrent substudy of cognitive function (target 2800 participants). Each individual was assessed with a screening cognitive test battery and an extended cognitive test battery at baseline and biennially during the planned 4-year follow-up. The primary outcomes for this substudy were standardised composite scores for memory (Logical Memory I and II, Modified Rey-Osterrieth Complex Figure [immediate recall], and Hopkins Verbal Learning Test-Revised [delayed recall]) and processing speed (Trail Making Test and Digit Symbol Coding). SPRINT was registered with ClinicalTrials.gov, NCT01206062. FINDINGS: From Nov 23, 2010, to Dec 28, 2012, 2921 participants (mean age 68·4 years [SD 8·6], 1080 [37%] women) who had been randomly assigned in SPRINT were enrolled in the substudy (1448 received intensive treatment and 1473 received standard treatment). SPRINT was terminated early due to benefit observed in the primary outcome (composite of cardiovascular events). After a median follow-up of 4·1 years (IQR 3·7-5·8), there was no between-group difference in memory, with an annual decline in mean standardised domain score of -0·005 (95% CI -0·010 to 0·001) in the intensive treatment group and -0·001 (-0·006 to 0·005) in the standard treatment group (between-group difference -0·004, 95% CI -0·012 to 0·004; p=0·33). Mean standardised processing speed domain scores declined more in the intensive treatment group (between-group difference -0·010, 95% CI -0·017 to -0·002; p=0·02), with an annual decline of -0·025 (-0·030 to -0·019) for the intensive treatment group and -0·015 (-0·021 to 0·009) for the standard treatment group. INTERPRETATION: Intensive treatment to lower systolic blood pressure did not result in a clinically relevant difference compared with standard treatment in memory or processing speed in a subgroup of participants from SPRINT. The effect of blood pressure lowering might not be evident in specific domains of cognitive function, but instead distributed across multiple domains.

BACKGROUND: Caring for a family member with dementia is extremely stressful, contributes to psychiatric and physical illness among caregivers, and increases the risk for caregiver death. Finding better ways to support family caregivers is a major public health challenge. OBJECTIVE: To test the effects of a structured multicomponent intervention on quality of life and clinical depression in caregivers and on rates of institutional placement of care recipients in 3 diverse racial or ethnic groups. DESIGN: Randomized, controlled trial. SETTING: In-home caregivers in 5 U.S. cities. PARTICIPANTS: 212 Hispanic or Latino, 219 white or Caucasian, and 211 black or African-American caregivers and their care recipients with Alzheimer disease or related disorders. INTERVENTION: Caregivers within each racial or ethnic group were randomly assigned to an intervention or to a control group. The intervention addressed caregiver depression, burden, self-care, and social support and care recipient problem behaviors through 12 in-home and telephone sessions over 6 months. Caregivers in the control group received 2 brief "check-in" telephone calls during the 6-month intervention. MEASUREMENTS: The primary outcome was a quality-of-life indicator comprising measures of 6-month caregiver depression, burden, self-care, and social support and care recipient problem behaviors. Secondary outcomes were caregiver clinical depression and institutional placement of the care recipient at 6 months. RESULTS: Hispanic or Latino and white or Caucasian caregivers in the intervention group experienced significantly greater improvement in quality of life than those in the control group (P < 0.001 and P = 0.037, respectively). Black or African-American spouse caregivers also improved significantly more (P = 0.003). Prevalence of clinical depression was lower among caregivers in the intervention group (12.6% vs. 22.7%; P = 0.001). There were no statistically significant differences in institutionalization at 6 months. LIMITATIONS: The study used only a single 6-month follow-up assessment, combined heterogeneous cultures and ethnicities into a single group, and excluded some ethnic groups. CONCLUSIONS: A structured multicomponent intervention adapted to individual risk profiles can increase the quality of life of ethnically diverse dementia caregivers. ClinicalTrials.gov identifier: NCT00177489.

BACKGROUND: Differences in self-reported disability may be found for older black and white adults with knee osteoarthritis (OA). METHODS: This secondary analysis of data from a randomized single-blind clinical trial examined race differences in the relationship between self-reports and timed performance tests of walking. Study participants were 518 older adults (131 blacks, 387 whites), including 363 women and 155 men, with an average age of 68.6 years. RESULTS: Older black and white adults with radiographically documented knee OA reported equivalent functional ability and pain severity. However, both blacks' OA severity rating and tested performance were significantly worse than those of whites. Self-report and tested walking performance were significantly less correlated among black older adults than among white older adults. Analyses of potential confounding variables documented that the difference was not due to marital status, gender, education, income, body mass index, comorbidity, pain level, OA severity or general health. CONCLUSIONS: Self-reports of OA disability were less related to tested performance for walking among black older adults. Clinicians' knowledge of black patients' underestimation of their disability has compelling potential for improving clinical treatment and enhancing diagnostic approaches to care of older adults.

The Resources for Enhancing Alzheimer's Caregivers Health in the VA (REACH VA) dementia caregiving intervention has been implemented in the VA, in community agencies, and internationally. As identified in the 2013 and 2015 National Plan to Address Alzheimer's Disease, REACH is being made available to American Indian and Alaska Native communities. Implementation activities are carried out by local Public Health Nursing programs operated by Indian Health Service and Tribal Health programs, and Administration for Community Living/Administration on Aging funded Tribal Aging program staff already working in each community. The implementation is described using the Fixsen and Blasé implementation process model. Cultural, community, health system, and tribe-specific adaptations occur during the six implementation stages of exploration and adoption, program installation, initial implementation, full operation, innovation, and sustainability. Adaptations are made by local staff delivering the program. Implementation challenges in serving AI/AN dementia caregivers include the need to adapt the program to fit the unique communities and the cultural perceptions of dementia and caregiving. Lessons learned highlight the importance of using a clinically successful intervention, the need for support and buy-in from leadership and staff, the fit of the intervention into ongoing routines and practices, the critical role of modifications based on caregiver, staff, and organization needs and feedback, the need for a simple and easily learned intervention, and the critical importance of community receptivity to the services offered.

OBJECTIVE: Examine caregiver and care recipient healthcare costs associated with caregivers' participation in Resources for Enhancing Alzheimer's Caregivers Health (REACH II or REACH VA) behavioral interventions to improve coping skills and care recipient management. DESIGN: RCT (REACH II); propensity-score matched, retrospective cohort study (REACH VA). SETTING: Five community sites (REACH II); 24 VA facilities (REACH VA). PARTICIPANTS: Care recipients with Alzheimer's disease and related dementias (ADRD) and their caregivers who participated in REACH II study (analysis sample of 110 caregivers and 197 care recipients); care recipients whose caregivers participated in REACH VA and a propensity matched control group (analysis sample of 491). MEASUREMENTS: Previously collected data plus Medicare expenditures (REACH II) and VA costs plus Medicare expenditures (REACH VA). RESULTS: There was no increase in VA or Medicare expenditures for care recipients or their caregivers who participated in either REACH intervention. For VA care recipients, REACH was associated with significantly lower total VA costs of care (33.6%). VA caregiver cost data was not available. CONCLUSION: In previous research, both REACH II and REACH VA have been shown to provide benefit for dementia caregivers at a cost of less than $5/day; however, concerns about additional healthcare costs may have hindered REACH's widespread adoption. Neither REACH intervention was associated with additional healthcare costs for caregivers or patients; in fact, for VA patients, there were significantly lower healthcare costs. The VA costs savings may be related to the addition of a structured format for addressing the caregiver's role in managing complex ADRD care to an existing, integrated care system. These findings suggest that behavioral interventions are a viable mechanism to support burdened dementia caregivers without additional healthcare costs.

PURPOSE OF THE STUDY: Health care and social services such as physician visits and support groups used by dementia caregivers for themselves were examined. Caregivers (N = 642) were from the Resources for Enhancing Alzheimer's Caregivers Health (REACH II) study. DESIGN AND METHODS: Caregiver predisposing, enabling, and need variables were examined using chi-squared and t-tests to characterize service users. Stagewise linear regression was used to explain numbers of services used. RESULTS: Predisposing, enabling, and need variables were significantly related to dementia caregivers' service use. In regression, caregivers who were older, more educated, married, not employed, depressed, with functional disability needs, more illness-related reduced activity days, more medications, more symptoms, and fewer hours on duty per day used significantly more services for themselves. The statistically significant model explained 22.2% variance in numbers of services used. Service users, compared with nonusers, evidenced greater burden, bother with behaviors, and more desire to institutionalize. IMPLICATIONS: This study shows that caregiver service use is related to caregiver characteristics. Future work should examine the impact of caregiving on health care and social service use and costs. The societal costs of caregiving may be better understood when we account for additional service use by caregivers themselves. A significant clinical and policy issue is who should assess and support the caregiver. Possibilities include the care recipient's health care practitioner, the caregiver's health care practitioner, or a formal caregiver-focused program based in the health care system or the social service network.

PURPOSE OF THE STUDY: Resources for Enhancing All Caregivers Health in the Department of Veterans Affairs (REACH VA) has been implemented in the VA system as a national program for caregivers. DESIGN AND METHODS: We describe the trajectory of REACH VA from national randomized clinical trial through translation to national implementation. The implementation is examined through the six stages of the Fixsen and Blasé implementation process model: exploration and adoption, program installation, initial implementation, full operation, innovation, and sustainability. Different drivers that move the implementation process forward are important at each stage, including staff selection, staff training, consultation and coaching, staff evaluation, administrative support, program evaluation/fidelity, and systems interventions. RESULTS: Caregivers in the REACH VA 4 session intervention currently implemented in the VA had similar outcomes to longer REACH interventions, including Resources for Enhancing Alzheimer's Caregivers Health (REACH II). Caregivers experienced significant decreases in burden, depression, anxiety, number of troubling patient behaviors reported, caregiving frustrations, stress symptoms (feeling overwhelmed, feeling like crying, being frustrated as a result of caregiving, being lonely), and general stress. Effect sizes (Cohen's d) for these significant variables were between small and medium ranging from .24 to .46. IMPLICATIONS: The implementation of REACH VA provides a road map for implementation of other behavioral interventions in health care delivery settings. Lessons learned include the importance of implementing a proven, needed intervention, support from both leadership and clinical staff, willingness to respond to staff and organization needs and modify the intervention while preserving its integrity, and fitting the intervention into ongoing routines and practices.
