Item Open Access An organizing framework for informal caregiver interventions: detailing caregiving activities and caregiver and care recipient outcomes to optimize evaluation efforts.(BMC geriatrics, 2011-11) Van Houtven, Courtney Harold; Voils, Corrine I; Weinberger, MorrisBackground
Caregiver interventions may help improve the quality of informal care. Yet the lack of a systematic framework specifying the targets and outcomes of caregiver interventions hampers our ability to understand what has been studied, to evaluate existing programs, and to inform the design of future programs. Our goal was to develop an organizing framework detailing the components of the caregiving activities and the caregiver and care recipient outcomes that should be affected by an intervention. In so doing, we characterize what has been measured in the published literature to date and what should be measured in future studies to enable comparisons across interventions and across time.Methods
Our data set comprises 121 reports of caregiver interventions conducted in the United States and published between 2000 and 2009. We extracted information on variables that have been examined as primary and secondary outcomes. These variables were grouped into categories, which then informed the organizing framework. We calculated the frequency with which the interventions examined each framework component to identify areas about which we have the most knowledge and under-studied areas that deserve attention in future research.Results
The framework stipulates that caregiver interventions seek to change caregiving activities, which in turn affect caregiver and care recipient outcomes. The most frequently assessed variables have been caregiver psychological outcomes (especially depression and burden) and care recipient physical and health care use outcomes.Conclusions
Based on the organizing framework, we make three key recommendations to guide interventions and inform research and policy. First, all intervention studies should assess quality and/or quantity of caregiving activities to help understand to what extent and how well the intervention worked. Second, intervention studies should assess a broad range of caregiver and care recipient outcomes, including considering whether expanding to economic status and health care use of the caregiver can be accommodated, to ease subsequent economic evaluations of caregiving. Third, intervention studies should measure a common set of outcomes to facilitate cross-time and cross-study comparisons of effectiveness.Item Open Access Comprehensive Family Caregiver Support and Caregiver Well-Being: Preliminary Evidence From a Pre-post-survey Study With a Non-equivalent Control Group.(Frontiers in public health, 2019-01) Smith, Valerie A; Lindquist, Jennifer; Miller, Katherine EM; Shepherd-Banigan, Megan; Olsen, Maren; Campbell-Kotler, Margaret; Henius, Jennifer; Kabat, Margaret; Van Houtven, Courtney HaroldIntroduction: In May 2010, the Caregivers and Veterans Omnibus Health Services Act of 2010, was signed into law in the United States, establishing the Program of Comprehensive Assistance for Family Caregivers (PCAFC) provided through the VA Caregiver Support Program (CSP). Prior to this program, over half of family caregivers reported being untrained for the tasks they needed to provide. The training through PCAFC represents the largest effort to train family caregivers in the U.S., and the features of the program, specifically a monthly stipend to caregivers and access to a Caregiver Support Coordinator at each VA medical center nationally, make it the most comprehensive caregiver support program ever enacted in the U.S. Methods: The purpose of this study is to examine the association between PCAFC participation and caregiver well-being following enrollment, comparing participating PCAFC caregivers to caregivers who applied to but were not approved for PCAFC participation (non-participants). Well-being is defined using three diverse but related outcomes: depressive symptoms, perceived financial strain, and perceived quality of the Veteran's health care. Additional well-being measures also examined include the Zarit Burden Inventory and positive aspects of caregiving. Results: The survey sample comprised of 92 caregivers approved for PCAFC and 66 caregivers not approved. The mean age of responding caregivers was 45; over 90% of caregivers were female; and over 80% of caregivers were married in both groups. We find promising trends in well-being associated with PCAFC participation. First, the perception of financial strain declined among participants compared to non-participants. Second, while depressive symptoms did not improve for the PCAFC caregivers, depressive symptoms increased among non-participants. Third, perceived quality of the Veteran's VA healthcare was no different between participants and non-participants. However, the 158 returned surveys reflect only a 5% response rate; hence this evidence is preliminary. Conclusion: Despite cautioning that results be interpreted as preliminary, this study provides unique descriptive information about young caregivers of U.S. post-9/11 Veterans, and offers a first step in filling the evidence gap about how comprehensive caregiver support in the U.S. may affect caregiver well-being. These preliminary findings should be explored and validated in a larger sample.Item Open Access Comprehensive Support for Family Caregivers of Post-9/11 Veterans Increases Veteran Utilization of Long-term Services and Supports: A Propensity Score Analysis.(Inquiry : a journal of medical care organization, provision and financing, 2018-01) Shepherd-Banigan, Megan; Smith, Valerie A; Stechuchak, Karen M; Miller, Katherine EM; Hastings, Susan Nicole; Wieland, Gilbert Darryl; Olsen, Maren K; Kabat, Margaret; Henius, Jennifer; Campbell-Kotler, Margaret; Van Houtven, Courtney HaroldFamily caregivers are an important component of the long-term services and supports (LTSS) system. However, caregiving may have negative consequences for caregiver physical and emotional health. Connecting caregivers to formal short-term home- and community-based services (HCBS), through information resources and referrals, might alleviate family caregiver burden and delay nursing home entry for the patient. The aim of this study was to evaluate the early impact of the Program of Comprehensive Assistance for Family Caregivers (PCAFC) (established by P.L. 111-163 for family caregivers of seriously injured post-9/11 Veterans) on Veteran use of LTSS. A two-cohort pre-post design with a nonequivalent comparison group (treated n = 15 650; comparison n = 8339) was used to (1) examine the association between caregiver enrollment in PCAFC and any VA-purchased or VA-provided LTSS use among Veterans and (2) describe program-related trends in HCBS and institutional LTSS use. The comparison group was an inverse-propensity-score weighted sample of Veterans whose caregivers applied for, but were not accepted into, the program. From baseline through 24 months post application, use of any LTSS ranged from 13.1% to 17.8% for Veterans whose caregivers were enrolled in PCAFC versus from 3.8% to 5.3% for Veterans in the comparison group. Participation in PCAFC was associated with a statistically significant increased use of any LTSS from 1 to 24 months post application (over time odds ratios ranged from 2.71 [95% confidence interval: 2.31-3.17] to 4.86 [3.93-6.02]). Support for family caregivers may enhance utilization of LTSS for Veterans with physical, emotional, and/or cognitive conditions.Item Open Access Control beliefs and risk for 4-year mortality in older adults: a prospective cohort study.(BMC geriatrics, 2017-01) Duan-Porter, Wei; Hastings, Susan Nicole; Neelon, Brian; Van Houtven, Courtney HaroldBackground
Control beliefs are important psychological factors that likely contribute to heterogeneity in health outcomes for older adults. We evaluated whether control beliefs are associated with risk for 4-year mortality, after accounting for established "classic" biomedical risk factors. We also determined if an enhanced risk model with control beliefs improved identification of individuals with low vs. high mortality risk.Methods
We used nationally representative data from the Health and Retirement Study (2006-2012) for adults 50 years or older in 2006 (n = 7313) or 2008 (n = 6301). We assessed baseline perceived global control (measured as 2 dimensions-"constraints" and "mastery"), and health-specific control. We also obtained baseline data for 12 established biomedical risk factors of 4-year mortality: age, sex, 4 medical conditions (diabetes mellitus, cancer, lung disease and heart failure), body mass index less than 25 kg/m2, smoking, and 4 functional difficulties (with bathing, managing finances, walking several blocks and pushing or pulling heavy objects). Deaths within 4 years of follow-up were determined through interviews with respondents' family and the National Death Index.Results
After accounting for classic biomedical risk factors, perceived constraints were significantly associated with higher mortality risk (third quartile scores odds ratio [OR] 1.37, 95% CI 1.03-1.81; fourth quartile scores OR 1.45, 95% CI, 1.09-1.92), while health-specific control was significantly associated with lower risk (OR 0.69-0.78 for scores above first quartile). Higher perceived mastery scores were not consistently associated with decreased risk. The enhanced model with control beliefs found an additional 3.5% of participants (n = 222) with low predicted risk of 4-year mortality (i.e., 4% or less); observed mortality for these individuals was 1.8% during follow-up. Compared with participants predicted to have low mortality risk only by the classic biomedical model, individuals identified by only the enhanced model were older, had higher educational status, higher income, and higher prevalence of diabetes mellitus and cancer.Conclusion
Control beliefs were significantly associated with risk for 4-year mortality; accounting for these factors improved identification of low-risk individuals. More work is needed to determine how assessment of control beliefs could enable targeting of clinical interventions to support at-risk older adults.Item Open Access Economic evaluation of telephone self-management interventions for blood pressure control.(American heart journal, 2012-06) Wang, Virginia; Smith, Valerie A; Bosworth, Hayden B; Oddone, Eugene Z; Olsen, Maren K; McCant, Felicia; Powers, Benjamin J; Van Houtven, Courtney HaroldBackground
Half of patients with hypertension have poor blood pressure (BP) control. Recent models for treating hypertension have integrated disease monitoring and telephone-based interventions delivered in patients' homes. This study evaluated the costs of the Hypertension Intervention Nurse Telemedicine Study (HINTS), aimed to improve BP control in veterans.Methods
Eligible veterans were randomized to either usual care or 1 of 3 telephone-based intervention groups using home BP telemonitoring: (1) behavioral management, (2) medication management, or (3) combined. Intervention costs were derived from information collected during the trial. Direct medical costs (inpatient, outpatient, and outpatient pharmacy, including hypertension-specific pharmacy) at 18 months by group were calculated using Veterans Affairs (VA) Decision Support System data. Bootstrapped CIs were computed to compare intervention and medical costs between intervention groups and usual care.Results
Patients receiving behavior or medication management showed significant gains in BP control at 12 months; there were no differences in BP control at 18 months. In subgroup analysis, patients with poor baseline BP control receiving combined intervention significantly improved BP at 12 and 18 months. In overall and subgroup samples, average intervention costs were similar in the 3 study arms, and at 18 months, there were no statistically significant differences in direct VA medical costs or total VA costs between treatment arms and usual care.Conclusions
To optimize investment in telephone-based home interventions such as the HINTS, it is important to identify groups of patients who are most likely to benefit from more intensive home BP management.Item Open Access Essential Long-Term Care Workers Commonly Hold Second Jobs and Double- or Triple-Duty Caregiving Roles.(Journal of the American Geriatrics Society, 2020-08) Van Houtven, Courtney Harold; DePasquale, Nicole; Coe, Norma BObjectives
Long-term care (LTC) facilities are particularly dangerous places for the spread of COVID-19 given that they house vulnerable high-risk populations. Transmission-based precautions to protect residents, employees, and families alike must account for potential risks posed by LTC workers' second jobs and unpaid care work. This observational study describes the prevalence of their (1) second jobs, and (2) unpaid care work for dependent children and/or adult relatives (double- and triple-duty caregiving) overall and by occupational group (registered nurses [RNs], licensed practical nurses [LPNs], or certified nursing assistants [CNAs]).Design
A descriptive secondary analysis of data collected as part of the final wave of the Work, Family and Health Study.Setting
Thirty nursing home facilities located throughout the northeastern United States.Participants
A subset of 958 essential facility-based LTC workers involved in direct patient care.Measurements
We present information on LTC workers' demographic characteristics, health, features of their LTC occupation, additional paid work, wages, and double- or triple-duty caregiving roles.Results
Most LTC workers were CNAs, followed by LPNs and RNs. Overall, more than 70% of these workers agreed or strongly agreed with this statement: "When you are sick, you still feel obligated to come into work." One-sixth had a second job, where they worked an average of 20 hours per week, and more than 60% held double- or triple-duty caregiving roles. Additional paid work and unpaid care work characteristics did not significantly differ by occupational group, although the prevalence of second jobs was highest and accompanying work hours were longest among CNAs.Conclusion
LTC workers commonly hold second jobs along with double- and triple-duty caregiving roles. To slow the spread of COVID-19, both the paid and unpaid activities of these employees warrant consideration in the identification of appropriate clinical, policy, and informal supports.

Few definitive guidelines exist for rigorous large-scale prospective evaluation of nonrandomized programs and policies that require longitudinal primary data collection. In Veterans Affairs (VA) we identified a need to understand the impact of a geriatrics primary care model (referred to as GeriPACT); however, randomization of patients to GeriPACT vs. a traditional PACT was not feasible because GeriPACT has been rolled out nationally, and the decision to transition from PACT to GeriPACT is made jointly by a patient and provider. We describe our study design used to evaluate the comparative effectiveness of GeriPACT compared to a traditional primary care model (referred to as PACT) on patient experience and quality of care metrics.Methods
We used prospective matching to guide enrollment of GeriPACT-PACT patient dyads across 57 VA Medical Centers. First, we identified matches based an array of administratively derived characteristics using a combination of coarsened exact and distance function matching on 11 identified key variables that may function as confounders. Once a GeriPACT patient was enrolled, matched PACT patients were then contacted for recruitment using pre-assigned priority categories based on the distance function; if eligible and consented, patients were enrolled and followed with telephone surveys for 18 months.Results
We successfully enrolled 275 matched dyads in near real-time, with a median time of 7 days between enrolling a GeriPACT patient and a closely matched PACT patient. Standardized mean differences of < 0.2 among nearly all baseline variables indicates excellent baseline covariate balance. Exceptional balance on survey-collected baseline covariates not available at the time of matching suggests our procedure successfully controlled many known, but administratively unobserved, drivers of entrance to GeriPACT.Conclusions
We present an important process to prospectively evaluate the effects of different treatments when randomization is infeasible and provide guidance to researchers who may be interested in implementing a similar approach. Rich matching variables from the pre-treatment period that reflect treatment assignment mechanisms create a high quality comparison group from which to recruit. This design harnesses the power of national administrative data coupled with collection of patient reported outcomes, enabling rigorous evaluation of non-randomized programs or policies.Item Open Access Invisible partners in care: Snapshot of well-being among caregivers receiving comprehensive support from Veterans Affairs.(Health science reports, 2019-03) Miller, Katherine EM; Lindquist, Jennifer H; Olsen, Maren K; Smith, Valerie; Voils, Corrine I; Oddone, Eugene Z; Sperber, Nina R; Shepherd-Banigan, Megan; Wieland, G Darryl; Henius, Jennifer; Kabat, Margaret; Van Houtven, Courtney HaroldBackground and aims
Since May 2011, over 23 000 caregivers of Veterans seriously injured on or after September 11, 2001 have enrolled in the Program of Comprehensive Assistance for Family Caregivers (PCAFC). PCAFC provides caregivers training, a stipend, and access to health care. The aim of this study is to describe the characteristics of caregivers in PCAFC and examine associations between caregiver characteristics and caregiver well-being outcomes.Methods
We sent a web survey invitation to 10 000 PCAFC caregivers enrolled as of September 2015. Using linear and logistic regressions, we examine associations between PCAFC caregiver characteristics and caregiver outcomes: perceived financial strain, depressive symptoms (Center for Epidemiologic Studies Depression Scale [CESD-10]), perceived quality of Veteran's Veterans Health Administration (VHA) care, and self-reported caregiver health.Results
We had complete survey data for 899 respondents. Since becoming a caregiver, approximately 50% of respondents reported reducing or stopping work. Mean time spent providing care was 3.8 years (median 3, IQR 1-5) with an average of 4.9 weekdays (median 5, IQR 5-5) and 1.9 weekend days (median 2, IQR 2-2). The mean CESD-10 score was 8.2 (median 7, 4-12), at the cutoff for screening positive for depressive symptoms. A longer duration of caregiving was associated with having 0.08 increase in rating of financial strain (95% CI, 0.02-0.14). Caregiver rating of the Veteran's health status as "fair" or better was a strong predictor of better caregiver outcomes, ie, self-reported caregiver health. However, higher levels of education were associated with worse caregiver outcomes, ie, lower global satisfaction with VHA care, higher CESD-10 score, and higher rating of financial strain.Conclusions
Higher depressive symptoms among longer duration caregivers, coupled with high rates of reductions in hours worked, suggest interventions are needed to address the long-term emotional and financial needs of these caregivers of post-9/11 Veterans and identify subpopulations at risk for worse outcomes.Item Open Access Living Arrangements of Older Adults and COVID-19 Risk: It Is Not Just Nursing Homes.(Journal of the American Geriatrics Society, 2020-07) Coe, Norma B; Van Houtven, Courtney HaroldItem Open Access The Relationship between Training and Mental Health among Caregivers of Individuals with Polytrauma.(Behavioural neurology, 2015-01) Stevens, Lillian Flores; Pickett, Treven C; Wilder Schaaf, Kathryn P; Taylor, Brent C; Gravely, Amy; Van Houtven, Courtney Harold; Friedemann-Sánchez, Greta; Griffin, Joan MThis was a hypothesis-generating exploration of relationships between caregiver training during TBI/polytrauma rehabilitation and caregiver mental health. In this cross-sectional study, 507 informal caregivers to US service members with TBI who received inpatient rehabilitation care in a Veterans Affairs' Polytrauma Rehabilitation Center from 2001 to 2009 completed a retrospective, self-report survey. Embedded in the survey were measures of caregiver mental health, including the National Institutes of Health's Patient Reported Outcome Measurement Information System (PROMIS) Anxiety and Depression Short Forms, the Rosenberg Self-Esteem scale, and the Zarit Burden Short Form. Though no groups endorsed clinical levels, mental health symptoms varied by caregiver training category (Trained, Not Trained, and Did Not Need Training). Caregivers who did not receive training on how to navigate healthcare systems endorsed higher depression and burden and lower self-esteem than those who did. Caregivers who did not receive training in supporting their care recipients' emotions endorsed higher anxiety, depression, and burden and lower self-esteem than those who did. Analyses also suggested a different association between training and mental health based on caregivers' relationship to the care recipient and the intensity of care recipient needs. Potential hypotheses for testing in future studies raised by these findings are discussed.Item Open Access Understanding the Context for Long-Term Care Planning.(Med Care Res Rev, 2016-06) Broyles, Ila H; Sperber, Nina R; Voils, Corrine I; Konetzka, R Tamara; Coe, Norma B; Van Houtven, Courtney HaroldEvolving family structure and economic conditions may affect individuals' ability and willingness to plan for future long-term care (LTC) needs. We applied life course constructs to analyze focus group data from a study of family decision making about LTC insurance. Participants described how past exposure to caregiving motivated them to engage in LTC planning; in contrast, child rearing discouraged LTC planning. Perceived institutional and economic instability drove individuals to regard financial LTC planning as either a wise precaution or another risk. Perceived economic instability also shaped opinions that adult children are ill-equipped to support parents' LTC. Despite concerns about viability of social insurance programs, some participants described strategies to maximize gains from them. Changing norms around aging and family roles also affected expectations of an active older age, innovative LTC options, and limitations to adult children's involvement. Understanding life course context can inform policy efforts to encourage LTC planning.
