Beta amyloid PET scans for dementia diagnoses: Practice and research implications from CARE-IDEAS.

Beta amyloid PET scans are a minimally invasive biomarker that may inform Alzheimer's disease (AD) diagnosis. The Caregiver's Reactions and Experience (CARE) study, an IDEAS supplement, aimed to understand experiences of PET scan recipients and their care partners regarding motivations for scans, reporting and interpreting results, and impact of results. Patients with mild cognitive impairment or dementia who agreed to join the CARE-IDEAS study and their care partners participated in a baseline survey and follow-up survey approximately 18 months later, supplemented by in-depth qualitative interviews with subsets of participants. Patients who received scans and volunteered for follow-up research were more likely to be male, better educated, and have higher income than the general population. Survey information was merged with Medicare data. This article integrates findings from several CARE-IDEAS publications and provides implications for practice and research. Although most participants accurately reported scan results, they were often confused about their meaning for prognosis. Some participants reported distress with results, but there were no significant changes in measured depression, burden, or economic strain over time. Many respondents desired more information about prognosis and supportive resources. Scan results were not differentially associated with changes in service use over time. Findings suggest a need for carefully designed and tested tools for clinicians to discuss risks and benefits of scans and their results, and resources to support patients and care partners in subsequent planning. Learning of scan results provides a point-of-contact that should be leveraged to facilitate shared decision-making and person-centered longitudinal AD care.

Elevated Amyloid-ß PET Scan and Cognitive and Functional Decline in Mild Cognitive Impairment and Dementia of Uncertain Etiology.

BACKGROUND: Elevated amyloid-ß (Aß) on positron emission tomography (PET) scan is used to aid diagnosis of Alzheimer's disease (AD), but many prior studies have focused on patients with a typical AD phenotype such as amnestic mild cognitive impairment (MCI). Little is known about whether elevated Aß on PET scan predicts rate of cognitive and functional decline among those with MCI or dementia that is clinically less typical of early AD, thus leading to etiologic uncertainty. OBJECTIVE: We aimed to investigate whether elevated Aß on PET scan predicts cognitive and functional decline over an 18-month period in those with MCI or dementia of uncertain etiology. METHODS: In 1,028 individuals with MCI or dementia of uncertain etiology, we evaluated the association between elevated Aß on PET scan and change on a telephone cognitive status measure administered to the participant and change in everyday function as reported by their care partner. RESULTS: Individuals with either MCI or dementia and elevated Aß (66.6% of the sample) showed greater cognitive decline compared to those without elevated Aß on PET scan, whose cognition was relatively stable over 18 months. Those with either MCI or dementia and elevated Aß were also reported to have greater functional decline compared to those without elevated Aß, even though the latter group showed significant care partner-reported functional decline over time. CONCLUSIONS: Elevated Aß on PET scan can be helpful in predicting rates of both cognitive and functional decline, even among cognitively impaired individuals with atypical presentations of AD.

Association between results of an amyloid PET scan and healthcare utilization in individuals with cognitive impairment.

BACKGROUND: The Imaging Dementia Evidence for Amyloid Scanning (IDEAS) study reports that amyloid PET scans help providers diagnose and manage Alzheimer's disease and related dementias (ADRD). Using CARE-IDEAS, an IDEAS supplemental study, we examined the association between amyloid PET scan result (elevated or non-elevated amyloid), patient characteristics, and participant healthcare utilization. METHODS: We linked respondents in CARE-IDEAS study to their Medicare fee-for-service records (n = 1333). We examined participants' cognitive impairment-related, outpatient, emergency department (ED), and inpatient encounters in the year before compared with the 2 years after the amyloid PET scan. RESULTS: Individuals with a non-elevated amyloid scan had more healthcare encounters throughout the overall study period than those with an elevated amyloid scan. Regardless of the amyloid scan result, cognitive impairment-related and outpatient encounters overall decreased, but ED and inpatient encounters increased in the 2 years after the scan compared with the year prior. There was minimal evidence of differences in healthcare utilization between participants with an elevated and non-elevated amyloid scan. CONCLUSIONS: There is no difference in change in healthcare utilization between people with scans showing elevated and non-elevated beta-amyloid.

Prevalence and incidence of depressive symptoms and diagnosis of depression as associated with elevated amyloid among Medicare beneficiaries with cognitive impairment.

BACKGROUND: Depression and cognitive impairment commonly co-occur, and it has been hypothesized that the two share pathological processes. Our objective for this study was to determine the relationship between elevated ß-amyloid level and the prevalence and incidence of depressive symptoms and diagnosed depression over two years among fee-for-service Medicare beneficiaries with cognitive impairment. METHODS: We utilized data from the CARE-IDEAS cohort study (N = 2078) including two measures of depressive symptoms (PHQ-2) and administrative claims data to identify pre-scan and incident depression diagnosis in subsample of fee-for-service Medicare beneficiaries (N = 1443). We used descriptive statistics and Poisson regression models with robust covariance. RESULTS: Beneficiaries whose scan results indicated not-elevated ß-amyloid were significantly more likely to have been diagnosed with depression pre-scan (46.4 % vs. 33.1 %). There was no significant association between elevated amyloid and the incidence of depressive symptoms or diagnosed depression. LIMITATIONS: The sample was limited to Medicare beneficiaries with cognitive impairment. Race/ethnic composition and education levels were not representative of the general population and there was substantial loss to follow-up. Mixed depressive / anxious episodes were captured as diagnoses of depression, potentially overestimating depression in this population. CONCLUSIONS: There was a high prevalence and incidence of diagnosed depression in this cohort of Medicare beneficiaries, but the incidence of depressive symptoms and diagnosed depression was not associated with elevated ß-amyloid.

Improvise, Adapt & Overcome: Successful Surgery-Sparing Prosthetic Hip Infection Antibiotic Suppression During COVID-19 Crisis.

CASE: A 79-year-old active male presented during the first COVID-19 pandemic surgery moratorium with late Staphylococcus lugdunensis periprosthetic total hip arthroplasty infection. Due to the unprecedented circumstances, novel treatment of IV and oral antibiotic suppression was trialed without preceding surgical intervention. At latest follow-up, the patient has two-year revision-free survival with normalization of inflammatory markers and MRI findings, and resolution of clinical symptoms. CONCLUSION: We report a novel surgery-sparing treatment for periprosthetic hip infection. Judicious caution should be used in the application of similar therapies, as host and organism characteristics likely contributed substantially to the success of this case.

Reactions to Amyloid PET Scan Results and Levels of Anxious and Depressive Symptoms: CARE IDEAS Study.

BACKGROUND AND OBJECTIVES: Few studies have examined care partners' reactions to their loved ones receiving amyloid-ß positron emission tomography (PET) scan results, which can be indicative of Alzheimer's disease. We explored care partners' reactions qualitatively, and checked the association of scan results and diagnostic category (dementia vs mild cognitive impairment [MCI]) with care partner anxious and depressive symptoms through quantitative analysis. RESEARCH DESIGN AND METHODS: Using data from 1,761 care partners in the Caregivers' Reactions and Experience, a supplemental study of the Imaging Dementia Evidence for Amyloid Scanning study, we applied an exploratory sequential mixed-methods design and examined the reactions of 196 care partners to receiving amyloid PET scan results through open-ended interview questions. Based on the qualitative content analysis, we hypothesized there would be an association of care partners' depressive (Patient Health Questionnaire-2) and anxious (6-item State-Trait Anxiety Inventory) symptoms with scan results and diagnostic category which we then tested with logistic regression models. RESULTS: Content analysis of open-ended responses suggests that when scan results follow the care partner's expectations, for example, elevated amyloid in persons with dementia, care partners report relief and gratitude for the information, rather than distress. Adjusted logistic regression models of survey responses support this finding, with significantly higher odds of anxiety, but not depressive symptoms, among care partners of persons with MCI versus dementia and elevated amyloid. DISCUSSION AND IMPLICATIONS: Care partners of persons with MCI reported distress and had higher odds of anxiety after receiving elevated amyloid PET scan results than care partners of persons with dementia. This has the potential to inform clinical practice through recommendations for mental health screening and referrals.

"I know that my role is going to change": a mixed-methods study of the relationship between amyloid-ß PET scan results and caregiver burden.

BACKGROUND: Caregiver burden consists of disease specific and perceived stressors, respectively referred to as objective and subjective indicators of burden, and is associated with negative outcomes. Previous research has found that care partners to persons living with cognitive impairment and elevated levels of amyloid-ß, as measured by a positron emission tomography (PET) scan, may experience caregiver burden. AIMS: To elucidate the relationship between amyloid scan results and subjective and objective indicators of burden. METHODS: A parallel mixed-methods design using survey data from 1338 care partners to persons with mild cognitive impairment (MCI) and dementia who received an amyloid scan from the CARE-IDEAS study; and semi-structured interviews with a subsample of 62 care partners. Logistic regression models were used to investigate objective factors associated with caregiver burden. A thematic analysis of semi-structured interviews was used to investigate subjective indicators by exploring care partners' perceptions of their role following an amyloid scan. RESULTS: Elevated amyloid was not associated with burden. However, the scan result influenced participants perceptions of their caregiving role and coping strategies. Care partners to persons with elevated amyloid expected increasing responsibility, whereas partners to persons without elevated amyloid and mild cognitive impairment did not anticipate changes to their role. Care partners to persons with elevated amyloid reported using knowledge gained from the scan to develop coping strategies. All care partners described needing practical and emotional support. CONCLUSIONS: Amyloid scans can influence subjective indicators of burden and present the opportunity to identify and address care partners' support needs.

Advance directives among cognitively impaired persons who had an amyloid PET scan and their care partners: a mixed-methods study.

BACKGROUND: Little research exists on the role of ß-amyloid PET scans as part of Alzheimer's diagnostic tests and documentation of end-of-life preferences for persons with cognitive impairment. The study objectives were to examine the association of amyloid PET scan results (elevated vs. not elevated amyloid levels) and diagnostic category (mild cognitive impairment vs. dementia) with the likelihood of having an advance directive (reported a median of 4.5 months post-scan); to explore perceptions of PET scan results and their influence on planning for the future among persons with cognitive impairment and their care partners. METHODS: Sequential, explanatory mixed-methods design using data from dyads in the CARE-IDEAS study: advance directives as a factor of diagnostic category and scan result using multivariable logistic regression models; thematic analysis of semi-structured interviews with persons with cognitive impairment and care partners to explore how scan results influenced documentation of future healthcare preferences. Participants included 1784 persons with cognitive impairment and care partners from the CARE-IDEAS study, and a subsample of 100 semi-structured telephone interviews. RESULTS: 81.6% of dyads reported an advance directive. Non-Hispanic, White participants had higher rates of advance directives. There was no significant association between having an advance directive and scan results. Qualitative analysis provided insight into perceived urgency to have advance directives, evolving healthcare preferences, and the context of completing advance directives. CONCLUSIONS: Although amyloid PET scans prompted persons with cognitive impairment and care partners to consider progressive cognitive impairment as part of evolving healthcare preferences, we found substantial variability in the perceived urgency of documentation.

Amyloid-ß PET Scan Results Disclosure and Care-Partner Emotional Well-Being Over Time.

BACKGROUND: Diagnostic tests, such as amyloid-ß positron emission tomography (PET) scans, can increase appropriate therapeutic management for the underlying causes of cognitive decline. To evaluate the full utility of this diagnostic tool, information is needed on whether results from amyloid-ß PET scans influence care-partner outcomes. OBJECTIVE: This study examines the extent to which previous disclosure of elevated amyloid (suggestive of Alzheimer's disease (AD) etiology) versus not-elevated amyloid (not suggestive of AD etiology) is associated with changes in care-partner wellbeing. METHODS: The study used data derived from a national longitudinal survey of Medicare beneficiaries (n = 921) with mild cognitive impairment (MCI) or dementia and their care-partners. Care-partner wellbeing outcomes included depressive symptoms (PHQ-8), subjective burden (4-item Zarit burden score), and a 3-item measure of loneliness. Change was measured between 4 (Time 1) and 18 (Time 2) months after receiving the scan results. Adjusted linear regression models regressed change (Time 2-Time 1) in each outcome on scan result. RESULTS: Care-partners were primarily white, non-Hispanic, college-educated, and married to the care recipient. Elevated amyloid was not associated with statistically significant Time 1 differences in outcomes or with statistically significant changes in depressive symptoms 0.22 (-0.18, 0.61), subjective burden 0.36 (-0.01, 0.73), or loneliness 0.15 (-0.01, 0.32) for care-partners from one time point to another. CONCLUSION: Given advances in AD biomarker testing, future research in more diverse samples is needed to understand the influence of scan results on care-partner wellbeing across populations.

"Now at least we have something to call it": Patient and care partner experiences receiving an amyloid PET scan.

BACKGROUND: The primary objective of this paper was to examine perspectives and experiences of individuals with cognitive impairment who received an amyloid PET scan and their care partners, with regard to the process, logistics, and decision-making associated with receiving an amyloid PET scan and its results. METHODS: Structured telephone interviews were conducted with 200 randomly sampled scan recipient/care partner dyads from the CARE IDEAS study. The audio-recorded, transcribed responses were analyzed using an inductive qualitative content analytic approach. RESULTS: Participating individuals and care partners described their experiences in seeking a diagnosis for memory issues, including decision-making and logistics involved with receiving an amyloid PET scan. Participants discussed the factors contributing to their decision to seek a diagnosis for their memory issues and their hopes and expectations in completing the scan. Participants also described the trajectory of this process, and although some described relatively straightforward trajectories, others described problems associated with identifying appropriate providers and coordinating care across numerous providers to obtain a diagnosis for their memory issues. Participants described an additional challenge of physicians attributing cognitive decline to normal aging, rather than signs of a neurodegenerative disorder. CONCLUSIONS: Findings shed light on the barriers and delays that individuals and care partners experience in connecting with physicians and obtaining a comprehensive evaluation for cognitive problems. Results from this study have implications for physicians who provide care to older adults, and specifically highlight the need for greater care coordination and clearer communication with and systems of referral for patients.

Health Care and Community-Based Organization Partnerships to Address Social Needs: Medicare Advantage Plan Representatives' Perspectives.

Payers and providers are increasingly being held accountable for the overall health of their populations and may choose to partner with community-based organizations (CBOs) to address members' social needs. This study examines the opportunities and challenges that health care entities, using Medicare Advantage (MA) plans as an example, encounter when forming these relationships. We conducted interviews with 38 representatives of 17 MA organizations, representing 65% of MA members nationally. Transcripts were qualitatively analyzed to understand overarching themes. Participants described qualities they look for in community partners, including an alignment of organizational missions and evidence of improved outcomes. Participants also described challenges in working with CBOs, including needing an evidence base for CBOs' services and an absence of organizational infrastructure. Results demonstrate areas where CBOs may target their efforts to appeal to payers and providers and reveal a need for health care entities to assist CBOs in acquiring skills necessary for partnerships.

Emergency physician perspectives on using telehealth with older adults during COVID-19: A qualitative study.

OBJECTIVES: Emergency medicine physicians have played a pivotal role throughout the coronavirus disease 19 (COVID-19) pandemic through in-person and remote management and treatment. Our primary objectives were to understand emergency medicine physicians' experiences using telehealth throughout the pandemic, any facilitators/barriers to successful usage, lessons learned during implementation, and successful/abandoned strategies used to engage with older adults. METHODS: Using a semi-structured interview guide, we conducted 30-min interviews. We used purposeful sampling to recruit emergency medicine physicians from all United States regions, rural-urban settings, and academic and community practices, who reported caring for patients 65 years or older in-person or virtually during the pandemic. Interviews were audio-recorded, transcribed, double-coded, and analyzed for emergent themes using framework analysis. RESULTS: A total of 15 in-depth interviews were completed from September to November 2020. Physicians had a median age of 37 years, 7 were women, and 9 had experience with telehealth before the pandemic. We identified several themes: (1) there were various motivations for telehealth use; (2) telehealth was used primarily to supplement, not replace in-person care; (3) most platforms were easy to use; (4) patients and caregivers had high acceptability of telemedicine; and (5) older adults with sensory and cognitive impairments often relied on caregivers. Emergency medicine physicians played a critical role during primary care office closures during the first wave-dispelling misinformation about COVID-19, triaging patients to testing and treatment, and providing care that would otherwise have been deferred. CONCLUSIONS: Our data show that telemedicine gained acceptability among emergency medicine physicians and provided options to patients who may have otherwise deferred care. These findings can inform future healthcare delivery for acute care needs or pandemic responses.

Nursing home leaders' perceptions of a research partnership.

BACKGROUND/OBJECTIVE: Partnerships between healthcare providers and researchers may accelerate the translation of interventions into widespread practice by testing them under real-world conditions, but depend on provider's willingness to engage with researchers and ability to fully implement an intervention. AIM: To understand nursing home leader's motivations for participating in a research study and perceptions of the process and value. METHODS: After a feasibility study of tuned lighting in a nursing home, we conducted semi-structured telephone interviews with six facility leaders. Interviews were audio-recorded, transcribed, and independently coded by four investigators. RESULTS: Three themes emerged: (1) The importance of the nursing home's culture and context: the facility had stable leadership, clear processes for prioritizing and implementing new initiatives, and an established interest in the study's topic. (2) The importance of leader's belief in the value of the intervention: leaders perceived research generally and the intervention specifically as positively impacting their facility and residents. (3) The importance of ongoing collaboration and flexibility throughout the study period: leaders served as champions to catalyze the project and overcome implementation barriers. CONCLUSION: Nursing home leader's perspectives about their participation in a feasibility study underscore the importance of establishing strong researcher-provider partnerships, understanding the environment in which the intervention will be implemented, and employing pragmatic methods that allow for flexibility in response to real-world implementation barriers. We recommend eliciting qualitative information to understand the environment in which an intervention will be implemented and to engage opinion leaders who can inform the protocol and champion its success.

Front-line Nursing Home Staff Experiences During the COVID-19 Pandemic.

OBJECTIVE: The Coronavirus disease 2019 (COVID-19) pandemic is an unprecedented challenge for nursing homes, where staff have faced rapidly evolving circumstances to care for a vulnerable resident population. Our objective was to document the experiences of these front-line health care professionals during the pandemic. DESIGN: Electronic survey of long-term care staff. This report summarizes qualitative data from open-ended questions for the subset of respondents working in nursing homes. SETTING AND PARTICIPANTS: A total of 152 nursing home staff from 32 states, including direct-care staff and administrators. METHODS: From May 11 through June 4, 2020, we used social media and professional networks to disseminate an electronic survey with closed- and open-ended questions to a convenience sample of long-term care staff. Four investigators identified themes from qualitative responses for staff working in nursing homes. RESULTS: Respondents described ongoing constraints on testing and continued reliance on crisis standards for extended use and reuse of personal protective equipment. Administrators discussed the burden of tracking and implementing sometimes confusing or contradictory guidance from numerous agencies. Direct-care staff expressed fears of infecting themselves and their families, and expressed sincere empathy and concern for their residents. They described experiencing burnout due to increased workloads, staffing shortages, and the emotional burden of caring for residents facing significant isolation, illness, and death. Respondents cited the presence or lack of organizational communication and teamwork as important factors influencing their ability to work under challenging circumstances. They also described the demoralizing impact of negative media coverage of nursing homes, contrasting this with the heroic public recognition given to hospital staff. CONCLUSIONS AND IMPLICATIONS: Nursing home staff described working under complex and stressful circumstances during the COVID-19 pandemic. These challenges have added significant burden to an already strained and vulnerable workforce and are likely to contribute to increased burnout, turnover, and staff shortages in the long term.

How Accurately Do Patients and Their Care Partners Report Results of Amyloid-ß PET Scans for Alzheimer's Disease Assessment?

BACKGROUND: Amyloid-ß PET scans will likely become an integral part of the diagnostic evaluation for Alzheimer's disease if Medicare approves reimbursement for the scans. However, little is known about patients' and their care partners' interpretation of scan results. OBJECTIVE: This study seeks to understand how accurately patients with mild cognitive impairment (MCI) or dementia and their care partners report results of amyloid-ß PET scans and factors related to correct reporting. METHODS: A mixed-methods approach was used to analyze survey data from 1,845 patient-care partner dyads and responses to open-ended questions about interpretation of scan results from a sub-sample of 200 dyads. RESULTS: Eighty-three percent of patients and 85% of care partners correctly reported amyloid-ß PET scan results. Patients' higher cognitive function was associated with a small but significant decrease in the predicted probability of not only patients accurately reporting scan results (ME: -0.004, 95% CI: -0.007, -0.000), but also care partners accurately reporting scan results (ME: -0.006, 95% CI: -0.007, -0.001), as well as decreased concordance between patient and care partner reports (ME: -0.004, 95% CI: -0.007, -0.001). Content analysis of open-ended responses found that participants who reported the scan results incorrectly exhibited more confusion about diagnostic terminology than those who correctly reported the scan results. CONCLUSION: Overall, patients with MCI or dementia showed high rates of accurate reporting of amyloid-ß PET scan results. However, responses to questions about the meaning of the scan results highlight the need for improved provider communication, including providing written explanations and better prognostic information.

Why Older Adults and Their Children Disagree About In-Home Surveillance Technology, Sensors, and Tracking.

BACKGROUND AND OBJECTIVES: Despite the surveilling nature of technologies that allow caregivers to remotely monitor location, movements, or activities, the potential differences in comfort with remote monitoring between caregivers and care recipients have not been examined in depth. On the dyad and aggregate level, we compare preferences of older adult women and their adult children for three remote monitoring technologies. Their assessments of each technology's impact on privacy, safety, independence, freedom, relationship with family member, social life, and identity are also compared. RESEARCH DESIGN AND METHODS: This dyadic study used cognitive-based interview probing and value-centered design methods. Twenty-eight individual, in-depth, structured interviews were conducted with 18 women who are Meals on Wheels clients and 10 of their adult children. RESULTS: Meals on Wheels participants reported multiple chronic conditions and an average of 1.7 ADL and 3.3 IADL difficulties; two thirds were enrolled in Medicaid. Adult children preferred each technology more than their mothers did and underestimated both their mothers' ability to comprehend the functions of the technologies and the importance of engaging them fully in decision making. Most were confident that they could persuade their mothers to adopt. For both groups, privacy was the most-cited concern, and participants perceived significant overlap between values of privacy, independence, identity, and freedom. DISCUSSION AND IMPLICATIONS: Studying privacy in isolation overlooks privacy's instrumental role in enabling other values. Shared decision-making tools are needed to promote remote monitoring use consistent with older adults' values and to prevent conflict and caregiver overreach.

Medicare Advantage plan representatives' perspectives on Pay for Success.

OBJECTIVES: To understand how Medicare Advantage (MA) plan representatives perceive the alternative financing model Pay for Success (PFS) and its potential to address members' social risk factors. STUDY DESIGN: Semistructured qualitative interviews designed to understand plan representatives' priorities regarding addressing nonmedical needs of their members, awareness of and experiences with PFS, and thoughts about implementing PFS as a method to address members' nonmedical needs. METHODS: Interviews with 38 upper-management representatives from 17 MA plans, which represent 65% of MA beneficiaries nationally, were conducted from July to November 2018. Plans varied in geographic coverage, star rating, and enrollment. Transcripts were qualitatively analyzed to understand overarching themes and patterns of responses. RESULTS: MA plan representatives were largely unfamiliar with PFS and were interested in learning more about how it could address members' social needs. When probed about specific requirements of PFS, responses varied: Some reported willingness to share data with project partners and be reviewed by independent evaluators; others expressed their preference to keep data and performance analysis internal to the organization. Although most representatives prioritized innovation, some were more risk averse and preferred to use traditional methods to deliver new services. CONCLUSIONS: MA plan representatives were unfamiliar with PFS, but most expressed interest in it as an alternative model for funding initiatives to address members' social needs. Education of MA representatives about PFS as an alternative payment model for innovative programming is warranted. However, further guidance from CMS is needed to assuage the concerns raised by these representatives.

Perspectives of Medicare Advantage Plan Representatives on Addressing Social Determinants of Health in Response to the CHRONIC Care Act.

Importance: The passage of the Creating High-Quality Results and Outcomes Necessary to Improve Chronic (CHRONIC) Care Act in 2018 allows Medicare Advantage (MA) plans, which enroll more than one-third of Medicare beneficiaries, greater flexibility to address members' social determinants of health (SDOH) through supplemental benefits. Objective: To understand MA plan representatives' perspectives on the importance of addressing members' SDOH and their responses to the passage of the CHRONIC Care Act. Design, Setting, and Participants: This semistructured qualitative interview study conducted via telephone from July 6, 2018, to November 7, 2018, included participants from 17 MA plans that collectively enrolled more than 13 million MA members (>65% of the total MA market). Data analysis was conducted from September 18, 2018, to December 13, 2018. Main Outcomes and Measures: Audio-recorded interviews were transcribed and then analyzed using a modified content analysis approach to identify major themes and subthemes. Results: Thirty-eight participants representing 17 MA plans varying in region, star rating, and size were interviewed. Analysis of interviews revealed 3 key themes. The first theme was that participants increasingly recognize the value of addressing members' SDOH. The second theme was that participants had different perspectives on whether MA plans should directly address SDOH and how to do so. While some reported that they were taking advantage of the increased flexibility provided by the CHRONIC Care Act to design new benefits or partner with community-based organizations, others indicated that it was outside of their purview to directly address members' SDOH. The third theme was that participants described complex decision-making around how to provide supplemental benefits, including a need for evidence, return on investment, strong community partnerships, and guidance from the US Centers for Medicare & Medicaid Services. Conclusions and Relevance: These findings suggest that the changes in MA plans' benefit packages in response to the CHRONIC Care Act and their efforts to address SDOH will vary. Therefore, it is likely that MA enrollees will be differentially affected by the implementation of the CHRONIC Care Act.
