A Qualitative Evaluation of Caregiver Support Services Offered at the Atlanta Veterans Affairs Health Care System

Introduction The Department of Veterans Affairs (VA) provides health care to approximately 300,000 patients with dementia. Recognizing the critical role caregivers play in veterans’ health, the Cognitive Disorders Specialty Care Education Center of Excellence (COE) at the Atlanta VA Health Care System implemented a suite of caregiver support services, including formal programs and resource linkages. We evaluated the effectiveness of these services and identified caregiver-perceived gaps in them. Methods We conducted 11 semistructured interviews from November 2016 through February 2017 with caregivers of veterans seen in the COE who had participated in support services. After coding transcripts, we established a codebook of 9 major themes and conducted a thematic analysis of all transcripts. Results Caregivers spoke positively of COE caregiver services that offered information on dementia, social support, an emphasis on caregiver well-being and self-efficacy, and methods for behavioral change. Gaps identified included the need for additional dementia information and practical support in such matters as advanced directives and eligibility for VA benefits. Conclusion Our findings will inform future improvements to COE caregiver support services, such as an expansion of COE’s caregiver educational content and capacity building of existing components such as resource referrals. These results also highlight opportunities for COE to interface with internal and external organizations to enhance existing caregiver services.


Introduction
Dementia affects approximately 14% of US adults aged 70 or older. Prevalence and related health care costs are expected to rise as the overall population ages (1-3), and recent estimates suggest that the annual cost of dementia care may double to $109 billion by 2040 (1). Informal caregivers play a critical role in the US health system, acting as supplemental, uncompensated support outside of clinical spheres for patients with dementia (4). Previous studies identified various consequences of extended caregiving, including psychological distress and poor physical health (5)(6)(7). These consequences are related to perceived caregiver burden (8). However, only about 25% of caregivers report use of support services, which could reduce this burden (5).
Research teams and government agencies have implemented, evaluated, and translated evidence-based interventions focused on the needs of dementia caregivers; some programs demonstrated success in reducing caregiver burden and improving caregiver wellbeing while remaining cost-effective (9)(10)(11)(12). The Cognitive Disorders Specialty Care Education Center of Excellence (COE), an interprofessional collaborative practice at the Atlanta Veterans Affairs Health Care System (VAHCS), piloted a multicomponent intervention for primary caregivers of its dementia patients that includes services such as visits with staff social workers, resource referrals, and an evidence-based psychoeducational program, the Savvy Caregiver (13).
The primary objective of our formative evaluation was to examine the effectiveness of COE caregiver support services and referrals by using the Transactional Model of Stress and Coping (TMSC) as a framework (14). A secondary objective was to identify any gaps in these caregiver support services that, once addressed, would improve caregiver experiences as well as COE operations overall.

Methods
We conducted a qualitative, formative evaluation of COE caregiver support services from August 2016 through May 2017 in partnership with COE leadership, clinic staff members, and Emory University. The COE caregiver intervention components evaluated were the Savvy Caregiver Program, a 5-to-6-session psychoeducational training aimed at preparing dementia caregivers for the challenges of neurocognitive decline (13); the Tele-Savvy Program, a tablet-and internet-based remote adaptation of the Savvy Caregiver Program (15,16); caregiver visits and telephone calls with COE staff members (eg, nurse, social workers); and referrals to internal or external resources.
We used a purposive, nonprobability, convenience sample. The COE staff provided recommendations of eligible participants on the basis of the following criteria: 1) the caregiver was significantly involved in the outside support of a COE clinic patient diagnosed with dementia (ie, primary caregiver) and 2) the caregiver had participated in one or more COE caregiver support services. This evaluation was deemed nonresearch quality improvement by the Atlanta VAHCS Research Office and as such, did not require additional review by the Emory University institutional review board.
One researcher (S.B.) conducted 11 in-depth, semistructured interviews from November 2016 through February 2017 in private VAHCS offices, or by telephone when a caregiver was unable to travel. The participation rate was 65% (11 of 17). In general, nonparticipation was due to travel or caregiver time restrictions. With participant consent, the researcher used a VAHCS-approved device to audio-record all interviews and transcribed these interviews verbatim. Participants did not receive incentives for their time.
We used a standard interview guide developed in conjunction with COE leadership and Emory University faculty. Constructs from the TMSC (eg, primary and secondary appraisals, coping efforts) informed the development of interview questions. We categorized interview questions by the following domains of interest: demographics and other background information, previous caregiving experiences, present caregiving experiences, individual coping strategies, experiences with COE caregiver support services, and perceived gaps in these support services.
We completed transcript coding and analysis using MAXQDA 12 Base software (VERBI GmbH). We used a modified grounded theory approach in which the first collection of interviews informed later data collection and analysis strategies (17). One researcher (S.B.) coded an initial batch of transcripts and worked with the project team to develop and refine a codebook of 9 major themes. She then used the final codebook to code the remainder of the transcripts. A second coder (C.S.) coded 20% of the data to assess intercoder reliability and worked with S.B. to review and discuss all discrepancies between the coded transcripts until consensus was reached. S.B. applied any agreed-upon changes to the remaining transcripts. We synthesized and compared themes across all interviews to generate findings.

Results
All 11 caregivers were female spouses of veteran patients, with a mean age of 67 years (standard deviation [SD], 4.6 years; range, 57-72 years). Caregivers had been providing support to their spouse for a median of 6 years (range, 1.5-24.0 y) ( Table 1).
Caregivers remarked on the VA COE caregiver support services (Table 2). Overall, opinions of COE caregiver support services were positive. Five major themes emerged as effective components of these services: information about dementia, social support, a focus on caregiver self-efficacy, application of behavioral strategies, and an emphasis on caregiver well-being.
Information about dementia. Most caregivers (n = 10) appreciated dementia information that COE services provided. Information about dementia reinforced the notion that caregivers had no con-trol over disease progression, reducing feelings of guilt or responsibility. Caregivers who enrolled in the formal psychoeducational programs (ie, Savvy Caregiver and Tele-Savvy) were pleased with how the curriculum offered organized information on dementia, including what is normal and future prognosis. These caregivers noted how program information was used to tailor their routines to the unique symptoms and circumstances of various dementia stages. Program instruction seemed less constructive for caregivers managing late-stage dementia, for which care can be more taxing and complicated. Instead, one caregiver sought palliative care information from the internet and other avenues. In addition, 4 caregivers expressed difficulty in comprehending dementia symptoms, disease stages, and other information used to describe the veteran's illness.
Social support. Most caregivers who participated in the psychoeducational programs (n = 7) described the emotional benefits of interacting with other caregivers who were managing similar circumstances, noting a shared sense of empathy and encouragement. Caregivers were better able to "see what's coming" in terms of disease progression through sharing anecdotes, which better prepared them for their role. Caregivers also described using personal experiences to assist others, which facilitated community building (ie, being "in here together") and contrasted with instances when they repressed or shielded others from the difficulties of dementia caregiving. Additionally, caregivers discussed social support provided by COE clinic staff members who would purposefully reach out to caregivers to informally check in with them.
Caregiver self-efficacy. Seven caregivers noted increased self-efficacy, described as feeling more comfortable performing tasks typically ascribed to a caregiver, as a direct result of COE services. They recalled moments when they were better able to regulate their emotional responses to the veteran's behaviors after participation in the psychoeducational programs. With improved self-efficacy, caregivers felt less overwhelmed by their circumstances and better equipped to address challenges through such strategies as prioritizing tasks. Improved self-efficacy was more apparent among caregivers who participated in the psychoeducational programs than among those who did not.
Application of behavioral strategies. Six of the 11 caregivers described moments of consciously altering their behavior to reflect information gained from the COE staff and support services in an effort to respond more competently to the veteran's symptoms. These participants acknowledged using popular guidance from Savvy Caregiver materials, such as "Don't just do something; stand there." From this guidance, caregivers learned how to evaluate care recipient behavior and react supportively to each stage of the disease by using strategies such as meditation. Caregivers who had participated in the psychoeducational programs were more likely to be aware of appropriate behavioral strategies when caring for a patient with dementia and to adopt these practices into their routines.
Emphasis on caregiver well-being. Three caregivers noted difficulty in prioritizing personal needs because of the veteran's illness and deteriorating condition. Participants were, therefore, more likely to neglect their own health and well-being, citing instances of failing to schedule needed medical appointments, being unable to exercise, and experiencing chronic stress and disrupted sleep. Caregivers described how COE support services encouraged continued self-care (ie, caring for the caregiver) and emphasized how caregivers may struggle to continue supporting the veteran if they do not prioritize caring for themselves. In some cases, increased caregiver focus on their own well-being after COE program participation resulted in sustained behavior changes, such as better sleep management. An emphasis on caregiver well-being also prompted 2 caregivers to seek greater external support from loved ones, something they previously avoided.
Caregivers identified 4 gaps and recommended future COE services: 1) provide additional information on dementia, 2) provide additional support for individual caregiver challenges, 3) offer practical and logistical support (eg, navigating VA benefits, financial tasks), and 4) improve availability of formal caregiver programs.
Provide additional information on dementia. Although caregivers appreciated dementia information provided through COE services, 5 caregivers expressed a desire to acquire more detailed information about the disease and disease management. In particular, caregivers sought a clearer picture of the disease's expected pathology as a way to better manage their circumstances. Group interactions in COE programs also alerted caregivers to gaps in their dementia knowledge, and this prompted some to seek out additional dementia information and care that they may not have considered previously. Two caregivers were interested in information on end-oflife care, recognizing the importance of the topic but acknowledging that they felt overwhelmed about pursuing this discussion in detail.
Provide additional support for individual caregiver challenges. Seven caregivers emphasized a desire for support services that better addressed individual caregiver challenges. Three caregivers discussed alarming or frustrating behavior changes in the spouse that were likely manifesting because of dementia. One participant recalled her husband's obsessive behavior, explaining how she would have appreciated targeted support on how to manage this unique symptom. Caregivers emphasized that some concerns, such as increased sex drive or dementia-related infidelity, may be too PREVENTING CHRONIC DISEASE www.cdc.gov/pcd/issues/2019/18_0156.htm • Centers for Disease Control and Prevention personal to discuss with family and asked that COE services offer time to problem-solve specific dementia quirks with the staff or as a group, especially because other caregivers may have experienced similar difficulties.
Offer practical and logistical support. As a facet of navigating the VA health system, 6 caregivers indicated a need for increased practical and logistical support. Practical and logistical support encompassed external resource linkages, clarification on VA benefits and eligibility, and guidance on practical and legal matters such as advanced directives, financial management, and long-term care arrangements. Caregivers who were not familiar with the VA appeared to be at a particular disadvantage when navigating eligibility. Other caregivers wanted instruction on practical caregiving tasks, such as a do-not-resuscitate order for the spouse while he is still able to consent. Some caregivers noted that their husbands had handled household activities such as paying bills and overseeing investments and requested supplementary guidance on these tasks.
Improve Savvy Caregiver and Tele-Savvy course availability. Three caregivers would have liked the formal courses to be extended either through advanced modules or by increasing the number of sessions offered. Two caregivers requested an extension of the program over longer time intervals, and one caregiver described how it was difficult to keep up with weekly readings and assignments while acting as a caregiver. To accommodate caregivers who work full-time or have other commitments, one participant requested these programs be held at alternative times instead of weekday daytime hours.

Discussion
Our formative evaluation identified several components of COE caregiver services that were perceived as beneficial by participants. Caregivers responded positively to dementia information disseminated through COE services. This finding aligns with a previous meta-analysis of caregiver programs that found reductions in caregiver burden and emotional distress from interventions focused on increasing knowledge of the disease in an interactive format (18). To strengthen existing formal programs and resources that provide disease information, COE should consider expanding the current dementia curriculum for caregivers to provide supplementary details about the disease. With this updated curriculum, COE may address additional caregiver-requested content such as information that expands on introductory materials (eg, greater detail about disease stages), palliative care, and practical and logistical support. Some caregivers acknowledged challenges with comprehension of material on dementia topics. Research has shown that advanced health information may exacerbate caregiver distress if not presented in appropriate formats (19). COE should examine the health literacy levels of all dementia materials offered through caregiver services and refine materials as needed.
Consistent with previous research, caregivers attributed increased self-efficacy, behavior modification, and reduced feelings of caregiver burden to the Savvy Caregiver Program (13). Any expansion of COE services could consider methods to boost self-efficacy among caregivers of veterans beyond structured programs such as the Savvy Caregiver. Because self-efficacy is related to successfully completing tasks (20), caregiver self-efficacy may be improved through interactive mechanisms that encourage caregivers to share information about successfully managing their role. Additionally, novel alternatives such as home telehealth strategies would allow COE staff members to observe caregiving techniques used and offer constructive guidance (21).
Caregivers may neglect their needs or struggle to prioritize selfcare while providing support to care recipients (22). Findings from our evaluation suggest that an emphasis on caregiver well-being functions as an impetus for behavior change, with caregivers citing moments when they chose to pursue self-care strategies after psychoeducational programs and COE staff guidance. COE may consider developing print and other materials on well-being practices for caregivers not already engaged in COE services to increase its reach to those who may struggle to prioritize their wellbeing.
Social support from interactions with other caregivers and COE clinic staff members was particularly well-received, echoing one meta-analysis that found caregiver support group participants demonstrated significant emotional gains (23). However, current COE caregiver support services are not structured to sustain longterm support groups because COE formal caregiver programs are time-limited. Although the COE is currently piloting remote delivery through the Tele-Savvy Program, its staff should continue to expand caregiver support to internet-based models. Asynchronous, informal online support groups may provide a feasible, cost-effective alternative to more traditional in-person formats, and recent work has demonstrated benefits from online support communities for dementia caregivers (24)(25)(26). Additionally, internet-based education and support interventions, as an alternative to in-person scheduled instruction, have also proven effective for dementia caregivers (27,28). Web-based delivery of information and support would address caregiver concerns about course availability, because they could access COE resources on their own schedule. COE may consider implementing any of these informal virtual strategies to enhance remote delivery of dementia information and to sustain social support. Caregivers discussed a desire to engage with additional practical resources, similar to a previous study that found that only 19% of sampled caregivers were aware of how to access community services (29). COE could continue to offer and update a comprehensive resource list for caregivers that includes information on both health (eg, support groups) and practical resources (eg, legal counsel) to standardize and streamline referrals for external services in their local communities. In the future, COE may consider collaborating with other VA and external caregiver programs to expand services and to further address caregiver requests for more practical and logistical support.

PREVENTING CHRONIC DISEASE
Our study had several strengths. Because COE has documentation procedures for caregiver programs, such as rosters of psychoeducational program participants and clinical notes from caregiver interactions, we used well-maintained records to identify caregivers who had engaged in support services, which allowed us to capture multiple perspectives. Semistructured interviews provided caregivers with the appropriate conduit for more in-depth discussions of support services and the perceived effects these resources had on caregivers than quantitative surveys offer. In an attempt to reduce the likelihood of socially desirable responses, participants were informed that their feedback would not affect their benefits, and interviews were conducted by a third party not related to the provision of COE services.
Our formative evaluation also had some limitations. Because our analysis was qualitative and the sample size was small, findings are not generalizable to other caregiver populations or clinic environments outside the Atlanta VAHCS. However, the purpose of qualitative data is to provide insight, not generalizability, and the experiences of this sample aligned with published research on caregiver burden. Findings are also restricted to caregivers who engaged in caregiver support resources and who were interested in offering their perspectives on the program. COE is in the process of collecting complementary survey data before and after program participation to assess how factors related to caregiver burden, such as stress and depression, are influenced by COE support services and to bolster these qualitative findings. Future work should seek to explore the perspectives of caregivers who are less engaged in these services to improve reach. Future efforts may also incorporate staff perspectives on caregiver support services, a useful vantage point when considering program feasibility and sustainability. Any expansion or translation of COE caregiver services should ultimately undergo a full program evaluation.
Caregiver support services piloted by COE are well-regarded among dementia caregivers who use these resources to better manage the challenging circumstances and responsibilities of their role. Although caregivers noted some important limitations of these services that should be considered in the future, COE support services were found to be beneficial to caregivers through such mechanisms as increased knowledge of dementia, greater social support, increased self-efficacy to care for the veteran, behavior modification, and an emphasis on caregiver well-being. Findings from our formative evaluation support the continuation and expansion of these COE programs and demonstrate the usefulness of providing caregiver services through VA facilities to improve the care and quality of life of veterans living with dementia and their caregivers.
