Dementia Specialty Care Clinicians' Perspectives on Their Role in the Dementia Diagnostic Process and Diagnostic Disclosure.

BACKGROUND: Delivering a diagnosis of Alzheimer's disease and related dementias (ADRD) can be challenging not just for patients and families, but also for clinicians. Our objective was to understand dementia specialty care clinicians' perspectives on their role in diagnosis and diagnostic disclosure in dementia. METHODS: Qualitative interviews with clinicians from a specialty tertiary dementia care center focused on practices, challenges, and opportunities addressing patient and caregiver needs in dementia. Data was analyzed by an interdisciplinary team using thematic analysis. RESULTS: The 16 participants included behavioral neurologists, social workers, neuropsychologists, and nurses. Themes included the value of providing an accurate diagnosis, the timing and challenges of delivering a diagnosis, the central focus on diagnosis alongside the need for more education on care management, and the role of the interdisciplinary team. DISCUSSION: We identified areas for improvement and strengths that can be built upon or adapted to other settings, including providing clinicians in specialty and primary care settings more guidance and support when diagnostic challenges arise, strengthening interdisciplinary teamwork, and making dementia diagnosis and care more accessible.

Caregiver Experiences Navigating the Diagnostic Journey in a Rapidly Progressing Dementia.

INTRODUCTION: People with suspected Alzheimer's disease and related dementias (ADRD) and their families experience a burdensome process while seeking a diagnosis. These challenges are problematic in the most common dementia syndromes, but they can be even more distressing in rarer, atypical syndromes such as rapidly progressive dementias (RPDs), which can be fatal within months from onset. This study is an examination of the diagnostic journey experience from the perspective of caregivers of people who died from the prototypic RPD, sporadic Creutzfeldt-Jakob Disease (sCJD). METHODS: eIn this mixed-methods study, qualitative data were drawn from interviews with former caregivers of 12 people who died from sCJD. Chart review data were drawn from research and clinical chart data about the person with sCJD. Data were analyzed by a multidisciplinary research team using qualitative and descriptive statistical analysis. RESULTS: We identified 4 overarching themes that characterized the experience of the diagnostic journey in sCJD: clinician knowledge, clinician communication, experiences of uncertainty, and the caregiver as advocate. We also identified 4 phases along the diagnostic journey: recognition, the diagnostic workup, diagnosis, and post-diagnosis. Sub-themes within each phase include struggles to recognize what is wrong, complex processes of testing and referrals, delay and disclosure of diagnosis, and access to resources post-diagnosis. CONCLUSIONS: Findings suggest that more work is needed to improve clinician diagnostic knowledge and communication practices. Furthermore, caregivers need better support during the diagnostic journey. What we learn from studying sCJD and other RPDs is likely applicable to other more common dementias.

Antibias Efforts in United States Maternity Care: A Scoping Review of the Publicly Funded Health Equity Intervention Pipeline.

Antibias training is increasingly identified as a strategy to reduce maternal health disparities. Evidence to guide this work is limited. We conducted a community-guided scoping review to characterize new antibias research. Four of 508 projects met our criteria: US-based, publicly funded, initiated from January 1, 2018 to June 30, 2022, and featuring an intervention to reduce bias or racism in maternal health care providers. Training was embedded in multicomponent interventions in 3 projects, limiting its evaluation as a stand-alone intervention. Major public funders have sponsored few projects to advance antibias training research in maternal health. More support is needed to develop a rigorous and scalable evidence base.

Characteristics of people with dementia lost to follow-up from a dementia care center.

OBJECTIVE: To identify the prevalence and characteristics of people living with dementia (PLWD) lost to follow-up (LTFU) from a specialized dementia care clinic and to understand factors influencing patient follow-up status. METHODS: We conducted a retrospective chart review of PLWD seen at a dementia care clinic 2012-2017 who were deceased as of 2018 (n = 746). Participants were evaluated for follow-up status at the time of death. Generalized linear regression was used to analyze demographic and diagnostic characteristics by follow-up status. Text extracted from participant medical records was analyzed using qualitative content analysis to identify reasons patients became LTFU. RESULTS: Among PLWD seen at a dementia care clinic, 42% became LTFU before death, 39% of whom had chart documentation describing reasons for loss to follow-up. Increased rates of LTFU were associated with female sex (risk ratio 1.27, [95% confidence interval 1.09-1.49]; p = 0.003), educational attainment of high school or less (1.34, [1.13-1.61]; p = 0.001), and death in a long-term care facility (1.46, [1.19-1.80]; p = 0.003). Commonly documented reasons for not returning for care at the clinic included switching care to another provider (42%), logistical difficulty accessing care (26%), patient-family decision to discontinue care (24%), and functional challenges in accessing care (23%). CONCLUSIONS: PLWD are LTFU from specialized memory care at high rates. Attention to care coordination, patient-provider communication, and integrated use of alternative care models such as telehealth are potential strategies to improve care.

Patient and clinician perspectives on a patient-facing dashboard that visualizes patient reported outcomes in rheumatoid arthritis.

BACKGROUND: Poor patient-clinician communication around patient-reported outcomes (PROs) is a barrier to the effective management of rheumatoid arthritis (RA). We aimed to develop an RA 'dashboard' that could facilitate conversations about PROs and that would be acceptable to a wide range of patients, including English and Spanish speakers and patients with adequate or limited health literacy. METHODS: A diverse group of RA patients along with clinicians from two academic rheumatology clinics joined separate focus groups. We solicited feedback and made iterative changes to mock-ups of an RA dashboard that visualized PROs using a human-centred design process. We used the thematic analysis method to identify and characterize themes from the focus groups and used these insights to refine the dashboard. RESULTS: We conducted six focus groups involving 25 RA patients and three groups with 11 clinicians. Patients and clinicians agreed that the dashboard could enhance communication about PROs and RA disease activity and could promote patient self-management. Patients varied in their (a) comprehension, (b) preferences for the display and features of the dashboard, and (c) desired uses for the dashboard. Clinicians expressed significant concerns about the logistics of using the dashboard in clinical practice. CONCLUSION: Using principles of human-centred design, we created an RA dashboard that was well-accepted among patients and clinicians. The ability to customize the data display is important for tailoring the dashboard to patients with diverse needs and preferences. Special attention should be given to feasibility concerns voiced by clinicians.

Approaches to decision-making among late-stage melanoma patients: a multifactorial investigation.

PURPOSE: The treatment decisions of melanoma patients are poorly understood. Most research on cancer patient decision-making focuses on limited components of specific treatment decisions. This study aimed to holistically characterize late-stage melanoma patients' approaches to treatment decision-making in order to advance understanding of patient influences and supports. METHODS: (1) Exploratory analysis of longitudinal qualitative data to identify themes that characterize patient decision-making. (2) Pattern analysis of decision-making themes using an innovative method for visualizing qualitative data: a hierarchically-clustered heatmap. Participants were 13 advanced melanoma patients at a large academic medical center. RESULTS: Exploratory analysis revealed eight themes. Heatmap analysis indicated two broad types of patient decision-makers. "Reliant outsiders" relied on providers for medical information, demonstrated low involvement in decision-making, showed a low or later-in-care interest in clinical trials, and expressed altruistic motives. "Active insiders" accessed substantial medical information and expertise in their networks, consulted with other doctors, showed early and substantial interest in trials, demonstrated high involvement in decision-making, and employed multiple decision-making strategies. CONCLUSION: We identified and characterized two distinct approaches to decision-making among patients with late-stage melanoma. These differences spanned a wide range of factors (e.g., behaviors, resources, motivations). Enhanced understanding of patients as decision-makers and the factors that shape their decision-making may help providers to better support patient understanding, improve patient-provider communication, and support shared decision-making.

Interest in initiating an early phase clinical trial: results of a longitudinal study of advanced cancer patients.

OBJECTIVE: Enhanced recruitment of patients with advanced cancer (ACP) to early phase (EP) trials is needed. However, selective recruitment may affect the kinds of patients who are recruited. To address whether ACP who initiate EP trial enrollment differ from those who do not, we prospectively surveyed ACP well in advance of potential trial recruitment and followed them over time to identify those who initiated the recruitment process. METHODS: EP trial initiation was defined as a patient being referred for screening to an active EP trial. Depression and anxiety were assessed with the Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder Scale (GAD-7), respectively. Demographic and disease characteristics, functional status, and patient preferences regarding decision making were examined as possible predictors of EP trial initiation. RESULTS: Of the 78 advanced cancer patients in the cohort studied, 21 (27%) initiated EP trial participation, while 57 (73%) did not. Of those who initiated this process, 14 (67%) went on to enroll in an EP study. Level of depression severity was associated with EP trial initiation, with rates of initiation nearly three times higher (35% vs. 12%, p = 0.054) among patients with minimal to mild levels of depression compared to those with moderate or higher levels of depression. EP trial initiation was not associated with demographic or socioeconomic variables, cancer type, functional status, quality of life, or decision-making variables. CONCLUSIONS: The presence of elevated depressive symptoms may be associated with the EP trial recruitment and enrollment processes. This possible relationship warrants further study.

What advanced cancer patients with limited treatment options know about clinical research: a qualitative study.

PURPOSE: Discussions between oncologists and advanced cancer patients (ACPs) may touch on the complex issue of clinical trial participation. Numerous initiatives have sought to improve the quality of these potentially difficult conversations. However, we have limited data about what ACPs know about clinical research as they enter such discussions as, to date, such research has focused on the period following informed consent. This study examines ACPs' understanding of clinical research in the treatment period before consent. METHODS: We conducted in-depth interviews with adult ACPs with limited treatment options at four clinics in an academic medical center. So as not to influence patients' perspectives, interviewers probed patients' knowledge of clinical research only if the patient first brought up the topic. Interviews (40-60 min) were audio-recorded, transcribed, and analyzed thematically and via quantitative content analysis by an interdisciplinary team. RESULTS: Of 78 patients recruited, 56 (72%) spontaneously brought up the topic of clinical research during interview and are included in this analysis. Qualitative thematic analysis and quantitative content analysis revealed that patients' knowledge varied in terms of (1) accuracy and (2) specificity (level of detail). ACPs who spoke with high specificity were not always accurate, and ACPs with accurate knowledge included both high- and low-specificity speakers. CONCLUSIONS: ACPs' knowledge of clinical research is variable. Patients who can discuss the technical details of their care may or may not understand the broader purpose and procedures of clinical trials. Understanding this variability is important for improving patient-provider communication about clinical research and supporting efforts to provide individualized care for ACPs.

Dimerization of nitrophorin 4 at low pH and comparison to the K1A mutant of nitrophorin 1.

Nitrophorin 4, one of the four NO-carrying heme proteins from the salivary glands of Rhodnius prolixus, forms a homodimer at pH 5.0 with a Kd of ∼8 µM. This dimer begins to dissociate at pH 5.5 and is completely dissociated to monomer at pH 7.3, even at 3.7 mM. The dimer is significantly stabilized by binding NO to the heme and at pH 7.3 would require dilution to well below 0.2 mM to completely dissociate the NP4-NO homodimer. The primary techniques used for investigating the homodimer and the monomer-dimer equilibrium were size-exclusion fast protein liquid chromatography at pH 5.0 and (1)H{(15)N} heteronuclear single-quantum coherence spectroscopy as a function of pH and concentration. Preparation of site-directed mutants of NP4 (A1K, D30A, D30N, V36A/D129A/L130A, K38A, R39A, K125A, K125E, D132A, L133V, and K38Q/R39Q/K125Q) showed that the N-terminus, D30, D129, D132, at least one heme propionate, and, by association, likely also E32 and D35 are involved in the dimerization. The "closed loop" form of the A-B and G-H flexible loops of monomeric NP4, which predominates in crystal structures of the monomeric protein reported at pH 5.6 but not at pH 7.5 and which involves all of the residues listed above except D132, is required for dimer formation. Wild-type NP1 does not form a homodimer, but NP1(K1A) and native N-terminal NP1 form dimers in the presence of NO. The homodimer of NP1, however, is considerably less stable than that of NP4 in the absence of NO. This suggests that additional aspartate or glutamate residues present in the C-terminal region of NP4, but not NP1, are also involved in stabilizing the dimer.

NMR investigations of nitrophorin 2 belt side chain effects on heme orientation and seating of native N-terminus NP2 and NP2(D1A).

Nitrophorin 2 (NP2), one of the four NO-storing and NO-releasing proteins found in the saliva of the blood-sucking bug Rhodnius prolixus, has a more ruffled heme and a high preference for a particular heme orientation (B) compared with nitrophorin 1 and nitrophorin 4, which show not a preference (A to B ratio of approximately 1:1), suggesting that it fits more tightly in the ß-barrel protein. In this work we have prepared a series of "belt" mutants of NP2(D1A) and (ΔM0)NP2 aimed at reducing the size of aromatic or other residues that surround the heme, and investigated them as the high-spin aqua and low-spin N-methylimidazole complexes. The belt mutants included Y38A, Y38F, F42A, F66A, Y85A, Y85F, Y104A, I120T, and a triple mutant of NP2(D1A), the F42L, L106F, I120T mutant. Although I120 has been mainly considered to be a distal pocket residue, CδH3 of I120 lies directly above the heme 3-methyl, at 2.67 Å, of heme orientation B, or the 2-vinyl of A, and it thus plays a role as a belt mutant, a role that turns out to be extremely important in creating the strong favoring of the B heme orientation [A to B ratio of 1:14 for NP2(D1A) or 1:12 for (ΔM0)NP2]. The results show that the 1D (1)H NMR spectra of the high-spin forms are quite sensitive to changes in the shape of the heme binding cavity. The single mutation I120T eliminates the favorability of the B heme orientation by producing a heme A to B orientation ratio of 1:1, whereas the single mutation F42A reverses the heme orientation from an A to B ratio of 1:14 seen for NP2(D1A) to 10:1 for NP2(D1A,F42A). The most extreme ratio was found for the triple mutant of NP2(D1A), NP2(D1A,F42L,L105F,I120T), in which the A to B ratio is approximately 25:1, a ΔG change of about -3.5 kcal/mol or -14.1 kJ/mol with respect to NP2(D1A). The seating of the heme is modified as well in that mutant and in several others, by rotations of the heme by up to 4° from the seating observed in NP2(D1A), in order to relieve steric interactions between a vinyl ß-carbon and a protein side chain, or to fill a cavity created by replacing a large protein side chain by a much smaller one; the latter was observed for all tyrosine to alanine mutants. These relatively small changes in seating have a measurable effect on the NMR spectra of the mutants, but are indeed minor in terms of overall seating and reactivity of the NP2(D1A) protein. The (1)H NMR resonances of the hemin substituents of the low-spin N-methylimidazole complexes of NP2(D1A,F42L,L105F,I120T) as well as NP2(D1A,I120T), NP2(D1A,Y104A), and NP2(D1A,F42A) have been assigned using natural abundance (1)H{(13)C} heteronuclear multiple quantum correlation and (1)H-(1)H nuclear Overhauser effect spectroscopy spectra.

"Relationships, Very Quickly, Turn to Nothing": Loneliness, Social Isolation, and Adaptation to Changing Social Lives Among Persons Living With Dementia and Care Partners.

BACKGROUND AND OBJECTIVES: Persons with dementia and their care partners have known risks for loneliness and social isolation throughout the disease trajectory, yet little is described about social lives in a population heterogeneous for disease stage, syndrome type, and setting. RESEARCH DESIGN AND METHODS: We conducted a secondary analysis of qualitative interviews from multiple studies to triangulate responses from a cohort of persons with dementia (n = 24), and active (n = 33) or bereaved (n = 15) care partners diverse in setting, dementia type and stage, and life experience. Interviews explored challenges related to social lives and were analyzed thematically. RESULTS: Persons with dementia were on average 80 years old (range: 67-94), 38% female, and 78% diagnosed with Alzheimer's dementia; care partners were on average 67 years old (range: 40-87) and 69% female. We identified 3 primary themes. First, dyads lost external social networks due to complex factors, including discomfort of surrounding social networks, caregiving responsibilities, and progressive cognitive deficits. Second, care partners described disruptions of meaningful dyadic relationships due to progressive cognitive and functional deficits, leading to loneliness and anticipatory grief. Third, adaptive strategies centered on care partners facilitating shared social activities and programs addressing caregiver burden. An overarching theme of disease-course accumulation of barriers to social interactions and constant adaptations was present in all themes. DISCUSSION AND IMPLICATIONS: Isolation and loneliness are a shared experience and source of distress for persons with dementia and care partners. Results can inform interventions tailored to individual needs and disease stages of dyads that enhance social connectedness.

Design of High Affinity Binders to Convex Protein Target Sites.

While there has been progress in the de novo design of small globular miniproteins (50-65 residues) to bind to primarily concave regions of a target protein surface, computational design of minibinders to convex binding sites remains an outstanding challenge due to low level of overall shape complementarity. Here, we describe a general approach to generate computationally designed proteins which bind to convex target sites that employ geometrically matching concave scaffolds. We used this approach to design proteins binding to TGFßRII, CTLA-4 and PD-L1 which following experimental optimization have low nanomolar to picomolar affinities and potent biological activity. Co-crystal structures of the TGFßRII and CTLA-4 binders in complex with the receptors are in close agreement with the design models. Our approach provides a general route to generating very high affinity binders to convex protein target sites.

Challenges and Opportunities for Clinician Implicit Bias Training: Insights from Perinatal Care Stakeholders.

Introduction: In an attempt to address health inequities, many U.S. states have considered or enacted legislation requiring antibias or implicit bias training (IBT) for health care providers. California's "Dignity in Pregnancy and Childbirth Act" requires that hospitals and alternative birthing centers provide IBT to perinatal clinicians with the goal of improving clinical outcomes for Black women and birthing people. However, there is as yet insufficient evidence to identify what IBT approaches, if any, achieve this goal. Engaging the experiences and insights of IBT stakeholders is a foundational step in informing nascent IBT policy, curricula, and implementation. Methods: We conducted a multimethod community-based participatory research study with key stakeholders of California's IBT policy to identify key challenges and recommendations for effective clinician IBT. We used focus groups, in-depth interviews, combined inductive/deductive thematic analysis, and multiple techniques to promote rigor and validity. Participants were San Francisco Bay Area-based individuals who identified as Black or African American women with a recent hospital birth (n=20), and hospital-based perinatal clinicians (n=20). Results: We identified numerous actionable challenges and recommendations regarding aspects of (1) state law; (2) IBT content and format; (3) health care facility IBT implementation; (4) health care facility environment; and (5) provider commitment and behaviors. Patient and clinician insights overlapped substantially. Many respondents felt IBT would improve outcomes only in combination with other antiracism interventions. Health Equity Implications: These stakeholder insights offer policy-makers, health system leaders, and curriculum developers crucial guidance for the future development and implementation of clinician antibias interventions.

Native N-terminus nitrophorin 2 from the kissing bug: similarities to and differences from NP2(D1A).

The first amino acid of mature native nitrophorin 2 is aspartic acid, and when expressed in E. coli, the wild-type gene of the mature protein retains the methionine-0, which is produced by translation of the start codon. This form of NP2, (M0)NP2, has been found to have different properties from its D1A mutant, for which the Met0 is cleaved by the methionine aminopeptidase of E. coli (R. E. Berry, T. K. Shokhireva, I. Filippov, M. N. Shokhirev, H. Zhang, F. A. Walker, Biochemistry 2007, 46, 6830). Native N-terminus nitrophorin 2 ((ΔM0)NP2) has been prepared by employing periplasmic expression of NP2 in E. coli using the pelB leader sequence from Erwinia carotovora, which is present in the pET-26b expression plasmid (Novagen). This paper details the similarities and differences between the three different N-terminal forms of nitrophorin 2, (M0)NP2, NP2(D1A), and (ΔM0)NP2. It is found that the NMR spectra of high- and low-spin (ΔM0)NP2 are essentially identical to those of NP2(D1A), but the rate and equilibrium constants for histamine and NO dissociation/association of the two are different.

The Social Contexts of Birthing People with Public- and Private-Payer Prenatal Care: Illuminating an Understudied Aspect of the Patient Experience.

Purpose: In pursuit of more equitable and person-centered health care, patients and professional medical societies increasingly call for better clinician understanding of patients' perspectives and social contexts. A foundational but understudied aspect of patients' social contexts are the ideas they encounter about health-related behaviors. We investigated this aspect of the social contexts of birthing people, comparing those with public versus private insurance to discover setting-specific insights. Methods: Based on ethnographic fieldwork, we created an original survey featuring 29 statements about 12 prenatal, perinatal, and postpartum health behaviors (e.g., drinking alcohol, epidural use, breastfeeding). Participants were 248 individuals receiving prenatal care in Northern California in 2009-2011, split evenly between public- and private-payer coverage. Participants reported whether they were familiar or unfamiliar with each statement. Results: Ninety-eight percent of all participants had heard contradictory ideas about ≥1 health behavior (mean=3.9 behaviors for public- and 5.4 for private-coverage respondents). For 20 of the 29 behavior-related ideas, exposure varied significantly by coverage type. Among other differences, public-coverage respondents were much more familiar with ideas related to risk and constrained autonomy (e.g., that serious perinatal complications are common; that new mothers should try to breastfeed even if they do not want to). Conclusions: Birthing people are exposed to a wide range of ideas about health behaviors, many of which vary by the structural systems in which they are embedded. Understanding and engaging this complexity can help clinicians to provide more respectful, person-centered, and equitable maternity care.

Decision-making about clinical trial options among older patients with metastatic cancer who have exhausted standard therapies.

OBJECTIVES: Older adults under-enroll in early phase cancer clinical trials. There are limited data on their trial experiences, which hampers our ability to understand potential reasons and responses to under-enrollment. We aimed to explore older adults' experiences and deliberations with phase 1 trials. MATERIALS AND METHODS: We analyzed 101 in-depth interviews with 39 adults (average 2.6 interviews per participant) about their experiences with phase 1 trials. All respondents were ≥ 65 years and had advanced cancer. Interviews lasted 60-90 min and were audio-recorded, transcribed, and analyzed to identify respondents' understanding of clinical research, perceptions of early phase trials, and experiences with enrollment. RESULTS: Clinical trial participation was an interactive process that unfolded over time. Older adults relied on ongoing guidance and discussion with their oncologist to navigate the process. Respondents were generally interested in life-prolonging therapies, including enrollment in early phase clinical trials, but did not necessarily state this explicitly to their oncologist. While respondents did not mention age as a limitation to trials participation, participants age > 70 were less enthusiastic about participation and more often discussed their quality of life and weighed benefits of trial participation in the context of their remaining months of life. CONCLUSION: Early phase clinical trial enrollment is complex, and older adults rely on their oncologist to navigate this process. Acknowledging this complexity through shared decision-making may ensure that older adults have appropriate opportunities to enroll in early phase clinical trials and guard against inappropriate under-enrollment.

"Captive by the Uncertainty"-Experiences with Anticipatory Guidance for People Living with Dementia and Their Caregivers at a Specialty Dementia Clinic.

BACKGROUND: After a diagnosis of Alzheimer's disease and related disorders, people living with dementia (PWD) and caregivers wonder what disease trajectory to expect and how to plan for functional and cognitive decline. This qualitative study aimed to identify patient and caregiver experiences receiving anticipatory guidance about dementia from a specialty dementia clinic. OBJECTIVE: To examine PWD and caregiver perspectives on receiving anticipatory guidance from a specialty dementia clinic. METHODS: We conducted semi-structured interviews with PWD, and active and bereaved family caregivers, recruited from a specialty dementia clinic. Interviews were recorded, transcribed, and systematically summarized. Thematic analysis identified anticipatory guidance received from clinical or non-clinical sources and areas where respondents wanted additional guidance. RESULTS: Of 40 participants, 9 were PWD, 16 were active caregivers, and 15 were bereaved caregivers. PWD had a mean age of 75 and were primarily male (n = 6/9); caregivers had a mean age of 67 and were primarily female (n = 21/31). Participants felt they received incomplete or "hesitant" guidance on prognosis and expected disease course via their clinicians and filled the gap with information they found via the internet, books, and support groups. They appreciated guidance on behavioral, safety, and communication issues from clinicians, but found more timely and advance guidance from other non-clinical sources. Guidance on legal and financial planning was primarily identified through non-clinical sources. CONCLUSION: PWD and caregivers want more information about expected disease course, prognosis, and help planning after diagnosis. Clinicians have an opportunity to improve anticipatory guidance communication and subsequent care provision.

Developing neuropalliative care for sporadic Creutzfeldt-Jakob Disease.

We aimed to identify targets for neuropalliative care interventions in sporadic Creutzfeldt-Jakob disease by examining characteristics of patients and sources of distress and support among former caregivers. We identified caregivers of decedents with sporadic Creutzfeldt-Jakob disease from the University of California San Francisco Rapidly Progressive Dementia research database. We purposively recruited 12 caregivers for in-depth interviews and extracted associated patient data. We analysed interviews using the constant comparison method and chart data using descriptive statistics. Patients had a median age of 70 (range: 60-86) years and disease duration of 14.5 months (range 4-41 months). Caregivers were interviewed a median of 22  (range 11-39) months after patient death and had a median age of 59 (range 45-73) years. Three major sources of distress included (1) the unique nature of sporadic Creutzfeldt-Jakob disease; (2) clinical care issues such as difficult diagnostic process, lack of expertise in sporadic Creutzfeldt-Jakob disease, gaps in clinical systems, and difficulties with end-of-life care; and (3) caregiving issues, including escalating responsibilities, intensifying stress, declining caregiver well-being, and care needs surpassing resources. Two sources of support were (1) clinical care, including guidance from providers about what to expect and supportive relationships; and (2) caregiving supports, including connection to persons with experience managing Creutzfeldt-Jakob disease, instrumental support, and social/emotional support. The challenges and supports described by caregivers align with neuropalliative approaches and can be used to develop interventions to address needs of persons with sporadic Creutzfeldt-Jakob disease and their caregivers.

"I Didn't Sign Up for This": Perspectives from Persons Living with Dementia and Care Partners on Challenges, Supports, and Opportunities to Add Geriatric Neuropalliative Care to Dementia Specialty Care.

BACKGROUND: In the United States, dementia specialty centers affiliated with centers of excellence for research hold promise as locations to develop innovative, holistic care in care systems otherwise siloed by discipline or payer. OBJECTIVE: We conducted foundational research to inform development of patient-and family-centered palliative care interventions for dementia specialty centers. METHODS: We interviewed persons living with dementia (PLWD), current, and former care partners (CP) recruited from a specialty dementia clinic and purposively selected for variation across disease syndrome and stage. A framework method of thematic analysis included coding, analytic matrices, and pattern mapping. RESULTS: 40 participants included 9 PLWD, 16 current CPs, and 15 former CPs of decedents; 48% impacted by Alzheimer's disease dementia. While help from family, support groups and adult day centers, paid caregiving, and sensitive clinical care were invaluable to PLWD, CPs, or both, these supports were insufficient to navigate the extensive challenges. Disease-oriented sources of distress included symptoms, functional impairment and falls, uncertainty and loss, and inaccessible care. Social and relational challenges included constrained personal and professional opportunities. The obligation and toll of giving or receiving caregiving were challenging. Clinical care challenges for PLWD and/or CPs included care fragmentation, insufficient guidance to inform planning and need for expert interdisciplinary clinical care at home. CONCLUSION: Findings highlight the breadth and gravity of gaps, which surpass the disciplinary focus of either behavioral neurology or palliative care alone. Results can inform the development of novel interventions to add principles of geriatrics and neuropalliative care to dementia care.
