Adopting the RE-AIM analytic framework for rural program evaluation: experiences from the Advance Care Planning via Group Visits (ACP-GV) national evaluation.

Introduction: To support rigorous evaluation across a national portfolio of grants, the United States Department of Veterans Affairs (VA) Office of Rural Health (ORH) adopted an analytic framework to guide their grantees' evaluation of initiatives that reach rural veterans and to standardize the reporting of outcomes and impacts. Advance Care Planning via Group Visits (ACP-GV), one of ORH's Enterprise-Wide Initiatives, also followed the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework. ACP-GV is a national patient-centered intervention delivered in a large, veterans integrated healthcare system. This manuscript describes how RE-AIM was used to evaluate this national program and lessons learned from ORH's annual reporting feedback to ACP-GV on their use of the framework to describe evaluation impacts. Methods: We used patient, provider, and site-level administrative health care data from the VA Corporate Data Warehouse and national program management databases for federal fiscal years (FY) spanning October 1, 2018-September 30, 2023. Measures included cumulative and past FY metrics developed to assess program impacts. Results: RE-AIM constructs included the following cumulative and annual program evaluation results. ACP-GV reached 54,167 unique veterans, including 19,032 unique rural veterans between FY 2018 to FY 2023. During FY 2023, implementation adherence to the ACP-GV model was noted in 91.7% of program completers, with 55% of these completers reporting a knowledge increase and 14% reporting a substantial knowledge increase (effectiveness). As of FY 2023, 66 ACP-GV sites were active, and 1,556 VA staff were trained in the intervention (adoption). Of the 66 active sites in FY 2023, 27 were sites previously funded by ORH and continued to offer ACP-GV after the conclusion of three years of seed funding (maintenance). Discussion: Lessons learned developing RE-AIM metrics collaboratively with program developers, implementers, and evaluators allowed for a balance of clinical and scientific input in decision-making, while the ORH annual reporting feedback provided specificity and emphasis for including both cumulative, annual, and rural specific metrics. ACP-GV's use of RE-AIM metrics is a key step towards improving rural veteran health outcomes and describing real world program impacts.

Engaging stakeholders to retrospectively discern implementation strategies to support program evaluation: Proposed method and case study.

BACKGROUND: Availability of evidence-based practices (EBPs) is critical for improving health care outcomes, but diffusion can be challenging. Implementation activities increase the adoption of EBPs and support sustainability. However, when implementation activities are a part of quality improvement processes, evaluation of the time and cost associated with these activities is challenged by the need for a correct classification of these activities to a known taxonomy of implementation strategies by implementation actors. DESIGN: Observational study of a four-stage, stakeholder-engaged process for identifying implementation activities and estimating the associated costs. RESULTS: A national initiative in the Veterans Health Administration (VHA) to improve Advance Care Planning (ACP) via Group Visits (ACP-GV) for rural veterans identified 49 potential implementation activities. Evaluators translated and reduced these to 14 strategies used across three groups with the aid of implementation actors. Data were collected to determine the total implementation effort and applied cost estimates to estimate the budget impact of implementation for VHA. LIMITATIONS: Recall bias may influence the identification of potential implementation activities. CONCLUSIONS: This process improved understanding of the implementation effort and allowed estimation of ACP-GV 's budget impact. IMPLICATIONS: A four-stage, stakeholder-engaged methodology can be applied to other initiatives when a pragmatic evaluation of implementation efforts is needed.

Application of motivational interviewing to group: Teaching advance care planning via group visits for clinical professionals.

OBJECTIVE: Advance Care Planning (ACP) via Group Visits (ACP-GV) is an innovative patient-centered intervention used in the United States Department of Veterans Affairs (VA) healthcare system. The goal of ACP-GV is to spread ACP to veterans and caregivers in medically underserved rural areas. Veterans, caregivers and those they trust participate in a group led by clinicians in Veterans Health Administration healthcare and/or community-based settings. To learn how to facilitate ACP-GV, clinicians attend ACP-GV training. The training teaches the ACP-GV group model and the theoretical components of Motivational Interviewing (MI) (Rollnick & Miller, 1995), which are used to empower participants to have conversations about their healthcare values and preferences. Therefore, the aim is to describe the specific MI techniques utilized by group facilitators in the innovative ACP-GV intervention. DISCUSSION: We provide exemplars for how group facilitators apply the MI techniques to the group discussion with participants. Lastly, we provide a scripted case example of a coded MI-concordant session of ACP-GV delivered with veterans in a healthcare setting that can be used in future training and education for clinicians interested in facilitating ACP using a group modality. CONCLUSION: MI is a key aspect of delivering ACP-GV, a high-quality, patient-centered intervention for veterans, caregivers and those they trust.

"Advancing" Advance Care Planning to Veterans in the Veterans Health Administration.

INTRODUCTION: The completion rate of Advance Directive (ADs) in the Veterans Health Administration (VHA) is unknown. There is substantial literature on the need for effective Advance Care Planning (ACP) that leads to an AD to ensure that health care preferences for patients are known. Advance Directive are essential to consider since ACP, which explains and plans Advance Directive, does not reach all individuals. Health inequities, such as those experienced in rural areas, continue to exist. While ACP may disproportionately affect rural-residing veterans and their providers, a VHA program was specifically designed to increase ACP engagement with rural veterans and to address several systemic barriers to ACP. MATERIALS AND METHODS: This descriptive analysis seeks to identify patient, provider, and geographic characteristics associated with higher rates of ACP participation in VHA. An observational examination of the profile of veterans and the types of ACP (e.g., individual or in groups) using administrative data for all beneficiaries receiving VHA health care services in federal fiscal year (FY) 2020 was conducted as part of a national program evaluation. The measures include patient-level data on demographics (e.g., race, ethnicity, gender), unique patient identifiers (e.g., name, social security number), geographic characteristics of patient's location (e.g., rurality defined as Rural-Urban Commuting Areas [RUCA]), VHA priority group; provider-level data (e.g., type of document definition, clinic stop codes, visit date used to verify Advance Care Planning via Group Visits [ACP-GV] attendance; data not shown), and electronic health record note titles that indicated the presence of ACP in VHA (e.g., "Advance Directive [AD] Discussion" note title, "ACP-GV CHAR 4 code"). Pearson's chi-square statistics were used for between-group comparisons based on a two-sided test with a significance level of 0.05. RESULTS: The overall rate of AD discussions among unique VHA users in FY2020 was 5.2% (95% CI: 5.2%-5.2%) and for Advance Care Planning via Group Visits, which targets rural veterans using groups, it was 1.8% (95% CI: 1.8%-1.9%). Advance Directive discussions in VHA are more successful at reaching middle age (M = 64; SD = 16), African Americans, males, veterans living in urban areas, and veterans with a VA disability (Priority Group 1-4). Advance Care Planning delivered in groups is reaching slightly younger veterans under the age of 75 years (M = 62; SD = 15), African Americans, females, disabled veterans (e.g., Priority Group 1-4), and more veterans residing in rural communities compared to the national population of VHA users. CONCLUSION: Advance Directive discussion rates are low across VHA, yet intentional efforts with ACP via group visits are reaching veterans who are considered underserved owing to residing in rural areas. Advance Care Planning needs to be a well-informed clinical priority for VHA to engage with the entire veteran population and to support the completion of ADs.

Selective serotonin reuptake inhibitors-associated apathy syndrome: A cross sectional study.

Selective serotonin reuptake inhibitors (SSRIs), commonly used to treat depression, are associated with loss of motivation, anergy, and lack of curiosity often referred collectively as apathy. However, this association has not been systematically assessed using a specific rating scale for measuring apathy syndrome. Our objective was to study the association between SSRI use and apathy syndrome.We conducted a retrospective chart review of 125 patients enrolled in an outpatient psychiatry clinic. The prevalence of apathy syndrome and its clinical significance (based on standardized assessment) were compared between patients treated and not treated with SSRIs. Apathy was assessed using the Apathy Evaluation Scale-clinician version with a score ranging 18-72 with higher score for worse apathy. A score of greater than 30 is considered clinically significant apathy.Among 119 patients, the mean apathy scores were significantly higher in those treated with SSRIs compared to those not treated with SSRIs (42.5 ±â€Š9.2 vs 31.3 ±â€Š6, P < .0001). The SSRI group also had a significantly higher percentage of patients with clinically significant apathy (92% vs 61%, P < .0001). Use of all SSRIs was associated with the presence of apathy. Apathy was seen in all mental health diagnostic categories with highest Apathy evaluation scale-clinician version scores in those with dementia.SSRI use may be associated with higher rates of apathy syndrome. Clinicians should specifically inquire about iatrogenic apathy syndrome when evaluating patients on an SSRI if there is suspicion of loss of motivation. Limitations of this study included retrospective nature of this study, and that majority of the sample was males. Prospective studies are needed to elucidate information regarding the prevalence, etiology, and treatment response for SSRI-associated apathy syndrome.

Evaluation of the national implementation of the VA Diffusion of Excellence Initiative on Advance Care Planning via Group Visits: protocol for a quality improvement evaluation.

BACKGROUND: Traditionally, system leaders, service line managers, researchers, and program evaluators hire specifically dedicated implementation staff to ensure that a healthcare quality improvement effort can "go to scale." However, little is known about the impact of hiring dedicated staff and whether funded positions, amid a host of other delivered implementation strategies, are the main difference among sites with and without funding used to execute the program, on implementation effectiveness and cost outcomes. METHODS/DESIGN: In this mixed methods program evaluation, we will determine the impact of funding staff positions to implement, sustain, and spread a program, Advance Care Planning (ACP) via Group Visits (ACP-GV), nationally across the entire United States Department of Veterans Affairs (VA) healthcare system. In ACP-GV, veterans, their families, and trained clinical staff with expertise in ACP meet in a group setting to engage in discussions about ACP and the benefits to veterans and their trusted others of having an advance directive (AD) in place. To determine the impact of the ACP-GV National Program, we will use a propensity score-matched control design to compare ACP-GV and non-ACP-GV sites on the proportion of ACP discussions in VHA facilities. To account for variation in funding status, we will document and compare funded and unfunded sites on the effectiveness of implementation strategies (individual and combinations) used by sites in the National Program on ACP discussion and AD completion rates across the VHA. In order to determine the fiscal impact of the National Program and to help inform future dissemination across VHA, we will use a budget impact analysis. Finally, we will purposively select, recruit, and interview key stakeholders, who are clinicians and clinical managers in the VHA who offer ACP discussions to veterans, to identify the characteristics of high-performing (e.g., high rates or sustainers) and innovative sites (e.g., unique local program design or implementation of ACP) to inform sustainability and further spread. DISCUSSION: As an observational evaluation, this protocol will contribute to our understanding of implementation science and practice by examining the natural variation in implementation and spread of ACP-GV with or without funded staff positions.

Tutorial for using SliceOmatic to calculate thigh area and composition from computed tomography images from older adults.

OBJECTIVE: Area of muscle, fat, and bone is often measured in thigh CT scans when tissue composition is a key outcome. SliceOmatic software is commonly referenced for such analysis but published methods may be insufficient for new users. Thus, a quick start guide to calculating thigh composition using SliceOmatic has been developed. METHODS: CT images of the thigh were collected from older (69 ± 4 yrs, N = 24) adults before and after 12-weeks of resistance training. SliceOmatic was used to segment images into seven density regions encompassing fat, muscle, and bone from -190 to +2000 Hounsfield Units [HU]. The relative contributions to thigh area and the effects of tissue density overlap for skin and marrow with muscle and fat were determined. RESULTS: The largest contributors to the thigh were normal fat (-190 to -30 HU, 29.1 ± 7.4%) and muscle (35 to 100 HU, 48.9 ± 8.2%) while the smallest were high density (101 to 150 HU, 0.79 ± 0.50%) and very high density muscle (151 to 200 HU, 0.07 ± 0.02%). Training significantly (P<0.05) increased area for muscle in the very low (-29 to -1 HU, 5.5 ± 7.9%), low (0 to 34 HU, 9.6 ± 16.8%), normal (35 to 100 HU, 4.2 ± 7.9%), and high (100 to 150 HU, 70.9 ± 80.6%) density ranges for muscle. Normal fat, very high density muscle and bone did not change (P>0.05). Contributions to area were altered by ~1% or less and the results of training were not affected by accounting for skin and marrow. CONCLUSIONS: When using SliceOmatic to calculate thigh composition, accounting for skin and marrow may not be necessary. We recommend defining muscle as -29 to +200 HU but that smaller ranges (e.g. low density muscle, 0 to 34 HU) can easily be examined for relationships with the health condition and intervention of interest.

Engagement in steps of advance health care planning by homeless veterans.

Communicating health care preferences in advance, so that wishes can be honored if the person becomes unable to participate in decision-making, is especially important for vulnerable populations such as homeless veterans. Hospitals are required to inform patients of their rights to document their preferences, but completion rates for advance directives are low. Conceptualizing advance health care planning as a series of health behavior steps emphasizing communication is recommended for improving engagement in advance health care planning. The authors used program evaluation data from psychoeducational groups with 288 homeless veterans to learn about their previous experience with different steps of advance health care planning and their personal goals for future steps. Results revealed a significant discrepancy between what these veterans reported they have done and information available to health care providers in the medical record: Only 26% had an advance directive in the medical record, but 70% reported they had thought about the care they would want, and almost half reported they had talked with a trusted other or named someone to make decisions for them. The most frequent goal endorsed by veterans attending groups was discussing advance health care planning with family or trusted others and/or naming someone to be a decision maker. These findings indicate a need for improved communication and documentation of veteran preferences about emergency and end of life care. Results are also consistent with interventions tailored to varying readiness for different steps of advance health care planning. (PsycINFO Database Record

Concordance Between Veterans' Self-Report and Documentation of Surrogate Decision Makers: Implications for Quality Measurement.

CONTEXT: The Measuring What Matters initiative of the American Academy of Hospice and Palliative Medicine and the Hospice and Palliative Nurses Association identified documentation of a surrogate decision maker as one of the top 10 quality indicators in the acute hospital and hospice settings. OBJECTIVES: To better understand the potential implementation of this Measuring What Matters quality measure #8, Documentation of Surrogate in outpatient primary care settings by describing primary care patients' self-reported identification and documentation of a surrogate decision maker. METHODS: Examination of patient responses to self-assessment questions from advance health care planning educational groups conducted in one medical center primary care clinic and seven community-based outpatient primary care clinics. We assessed the concordance between patient reports of identifying and naming a surrogate decision maker and having completed an advance directive (AD) with presence of an AD in the electronic medical record. RESULTS: Of veterans without a documented AD on file, more than half (66%) reported that they had talked with someone they trusted and nearly half (52%) reported that they had named someone to communicate their preferences. CONCLUSIONS: Our clinical project data suggest that many more veterans may have initiated communications with surrogate decision makers than is evident in the electronic medical record. System changes are needed to close the gap between veterans' plans for a surrogate decision maker and the documentation available to acute care health care providers.

Feeling Heard and Understood: A Patient-Reported Quality Measure for the Inpatient Palliative Care Setting.

CONTEXT: As endorsed by the palliative care "Measuring What Matters" initiative, capturing patients' direct assessment of their care is essential for ongoing quality reporting and improvement. Fostering an environment where seriously ill patients feel heard and understood is of crucial importance to modern health care. OBJECTIVES: To describe the development and performance of a self-report field measure for seriously ill patients to report how well they feel heard and understood in the hospital environment. METHODS: As part of a larger ongoing cohort study of inpatient palliative care, we developed and administered the following point-of-care item: "Over the past two days, how much have you felt heard and understood by the doctors, nurses and hospital staff?" (completely, quite a bit, moderately, slightly, not at all). Participants completed the measure before and the day after palliative care consultation. For the postconsultation version, we changed the time frame from "past two days" to "today." RESULTS: One hundred sixty patients with advanced cancer completed the preconsultation assessment, and 87% of them completed the postconsultation version. Responses encompassed full use of the ordinal scale, did not exhibit ceiling or floor effects, and showed improvement from preassessment to postassessment. The item was quick to administer and easy for patients to complete. CONCLUSION: The "Heard & Understood" item is a promising self-report quality measure for the inpatient palliative care setting.

Immune Function and Muscle Adaptations to Resistance exercise in Older Adults: Study Protocol for a Randomized Controlled Trial of a Nutritional Supplement.

BACKGROUND: Immune function may influence the ability of older adults to maintain or improve muscle mass, strength, and function during aging. Thus, nutritional supplementation that supports the immune system could complement resistance exercise as an intervention for age-associated muscle loss. The current study will determine the relationship between immune function and exercise training outcomes for older adults who consume a nutritional supplement or placebo during resistance training and post-training follow-up. The supplement was chosen due to evidence suggesting its ingredients [arginine (Arg), glutamine (Gln), and ß-hydroxy ß-methylbutyrate (HMB)] can improve immune function, promote muscle growth, and counteract muscle loss. METHODS/DESIGN: Veterans (age 60 to 80 yrs, N = 50) of the United States military will participate in a randomized double-blind placebo-controlled trial of consumption of a nutritional supplement or placebo during completion of three study objectives: 1) determine if 2 weeks of supplementation improve immune function measured as the response to vaccination and systemic and cellular responses to acute resistance exercise; 2) determine if supplementation during 36 sessions of resistance training boosts gains in muscle size, strength, and function; and 3) determine if continued supplementation for 26 weeks post-training promotes retention of training-induced gains in muscle size, strength, and function. Analyses of the results for these objectives will determine the relationship between immune function and the training outcomes. Participants will undergo nine blood draws and five muscle (vastus lateralis) biopsies so that the effects of the supplement on immune function and the systemic and cellular responses to exercise can be measured. DISCUSSION: Exercise has known effects on immune function. However, the study will attempt to modulate immune function using a nutritional supplement and determine the effects on training outcomes. The study will also examine post-training benefit retention, an important issue for older adults, usually omitted from exercise studies. The study will potentially advance our understanding of the mechanisms of muscle gain and loss in older adults, but more importantly, a nutritional intervention will be evaluated as a complement to exercise for supporting muscle health during aging.

"Missing pieces": exploring cardiac risk perceptions in older women.

Approximately 95% of older women have factors that put them at risk for developing cardiovascular disease, but research indicates many do not perceive themselves to be at risk. We examined older women's perceived risk for coronary heart disease (CHD) and the factors influencing their perceptions. We conducted a descriptive, qualitative study using in-depth, individual interviews and quantitative measures to assess perceived risk and risk factors. Twenty-four older African American and Caucasian women had a mean 4.46 cardiac risk factors but perceived their own CHD risk as unrealistically low at 1.95 cm (SD = 1.57, on 0-to-8 cm visual analogue scale). Narrative data clustered in themes that represented a lack of fact-based information and multiple misconceptions about CHD and prevention. Major improvements in CHD health are only achievable if risk factors are prevented. This research suggests older women have substantial needs for consistent CHD information and prevention guidance.

Nurse executives' perceptions of end-of-life care provided in hospitals.

CONTEXT: With the aging of our population, almost one in five adults, or 19% of the population, will be older than 65 years by 2030. Many persons have expressed concern about the inadequate preparation of hospitals to provide high-value end-of-life care for the current and anticipated population of older adults. OBJECTIVES: The purpose of this study was to explore the perceptions of nurse executives about the provision of end-of-life care in the hospital setting. METHODS: We conducted a pilot, descriptive, naturalistic, qualitative study using in-person interviews to capture nurse executives' understandings, beliefs, and perceptions of end-of-life care in their facilities. RESULTS: Data were collected from 10 nurse executives. We identified five major factors, three barriers and two facilitators, in their descriptions of provision of end-of-life care provided in the hospital: 1) communication inadequacies, 2) education inadequacies, 3) hospital system constraints, 4) hospice services availability, and 5) nurse executive advocacy. CONCLUSION: These findings highlight the need for interventions that focus on improving communication at the bedside and in transitions of care, enhancing educational interventions, and developing patient-centered care systems, which translate into a higher quality end-of-life experience for patients and their family members. Nurse executives are currently an underused resource in end-of-life care but are poised to be able to champion innovative models and a culture of change that integrates high-value care for patients with serious and chronic illnesses.

Nutrient intake, peripheral edema, and weight change in elderly recuperative care patients.

BACKGROUND: It is unclear whether serial measures of body weight are valid indicators of nutritional status in older patients recovering from illness. Objectives. Investigate the relative influence of nutrient intake and changes in peripheral edema on weight change. METHODS: A prospective cohort study of 404 older men (mean age = 78.7±7.5 years) admitted to a transitional care unit of a Department of Veterans Affairs nursing home. Body weight and several indicators of lower extremity edema were measured at both unit admission and discharge. Complete nutrient intake assessments were performed daily. RESULTS: Over a median length of stay of 23 days (interquartile range: 15-41 days), 216 (53%) participants gained or lost more than or equal to 2.5% of their body weight. Two hundred eighty-two (70%) participants had recognizable lower extremity pitting edema at admission and/or discharge. The amount of weight change was strongly and positively correlated with multiple indicators of both nutrient intake and the change in the amount of peripheral edema. By multivariable analysis, the strongest predictor of weight change was maximal calf circumference change (partial R (2) = .35, p < .0001), followed by average daily energy intake (partial R (2) = .14, p < .0001), and the interaction of energy intake by time (partial R (2) = .02, p < .0001). CONCLUSIONS: Many older patients either gain or lose a significant amount of weight after admission to a transitional care unit. Because of the apparent high prevalence of co-occurring changes in total body water, the weight changes do not necessarily represent changes in nutritional status. Although repeat calf circumference measurements may provide some indication as to how much of the weight change is due to changes in body water, there is currently no viable alternative to monitoring the nutrient intake of older recuperative care patients in order to ensure that their nutrient needs are being met.

Changes in activities of daily living, nutrient intake, and systemic inflammation in elderly adults receiving recuperative care.

OBJECTIVES: To determine the relationships between physical function, systemic inflammation, and nutrient intake in elderly adults who are deconditioned or recovering from medical illness. DESIGN: Prospective observational study. SETTING: Recuperative care and rehabilitation setting of a Veterans Affairs hospital. PARTICIPANTS: Older adults assessed to be in need of and likely to benefit from specialized inpatient care (N = 336, aged 78.9 ± 7.5, median length of stay 24 days). MEASUREMENTS: Functional assessments and plasma analyses for albumins and inflammatory markers were performed at admission and discharge. Complete nutrient intake assessments were performed daily. Katz (independence in activities of daily living) and walking endurance (distance capability and summation of need for assistive device and human help) scores were based on direct observation and provider query. Data were analyzed using least-squares and logistic regression analyses. RESULTS: Changes in physical function between admission and discharge were positively correlated with change in nutrient intake and inversely correlated with inflammation at admission and its change. Participants in the upper quartile of change for nutrient intake (particularly improved protein intake) were two to three times as likely to experience a clinically significant change in functional status during the hospitalization. Similarly, the odds of experiencing an improvement in physical function were two to four times as great for participants whose C-reactive protein levels declined as for those whose levels increased. These relationships remained significant after controlling for age, length of stay, and other baseline indicators of health status. CONCLUSION: Protein intake and inflammation are significantly correlated with functional recovery for aging individuals undergoing recuperative care and rehabilitation. Future studies should investigate whether combined interventions that target these factors improve recovery during hospitalization for this population.

Wii-fit for improving gait and balance in an assisted living facility: a pilot study.

Objectives. To determine the effects on balance and gait of a Wii-Fit program compared to a walking program in subjects with mild Alzheimer's dementia (AD). Methods. A prospective randomized (1 : 1) pilot study with two intervention arms was conducted in an assisted living facility with twenty-two mild AD subjects. In both groups the intervention occurred under supervision for 30 minutes daily, five times a week for eight weeks. Repeated measures ANOVA and paired t-tests were used to analyze changes. Results. Both groups showed improvement in Berg Balance Scale (BBS), Tinetti Test (TT) and Timed Up and Go (TUG) over 8 weeks. However, there was no statistically significant difference between the groups over time. Intragroup analysis in the Wii-Fit group showed significant improvement on BBS (P = 0.003), and TT (P = 0.013). The walking group showed a trend towards improvement on BBS (P = 0.06) and TUG (P = 0.07) and significant improvement in TT (P = 0.06). Conclusion. This pilot study demonstrates the safety and efficacy of Wii-Fit in an assisted living facility in subjects with mild AD. Use of Wii-Fit resulted in significant improvements in balance and gait comparable to those in the robust monitored walking program. These results need to be confirmed in a larger, methodologically sound study.
