There is now an unprecedented opportunity to improve the care of the over 5 million people who are living with Alzheimer's disease and related dementias and many more with cognitive impairment due to brain injury, systemic diseases, and other causes. The introduction of a new Medicare care planning benefit-long sought openly by advocacy organizations and clinicians and badly needed by patients and families-could greatly improve health care quality, but only if widely and fully implemented. We describe the components of this new benefit and its promise of better clinical care, as well as its potential to create a new platform for clinical and health outcomes research. We highlight external factors-and some that are internal to the benefit structure itself-that challenge the full realization of its value, and we call for broad public and professional engagement to ensure that it will not fail.

Hearing loss is remarkably prevalent in the geriatric population: one-quarter of adults aged 60-69 and 80% of adults aged 80 years and older have bilateral disabling loss. Only about one in five adults with hearing loss wears a hearing aid, leaving many vulnerable to poor communication with healthcare providers. We quantified the extent to which hearing loss is mentioned in studies of physician-patient communication with older patients, and the degree to which hearing loss is incorporated into analyses and findings. We conducted a structured literature search within PubMed for original studies of physician-patient communication with older patients that were published since 2000, using the natural language phrase "older patient physician communication." We identified 409 papers in the initial search, and included 67 in this systematic review. Of the 67 papers, only 16 studies (23.9%) included any mention of hearing loss. In six of the 16 studies, hearing loss was mentioned only; in four studies, hearing loss was used as an exclusion criterion; and in two studies, the extent of hearing loss was measured and reported for the sample, with no further analysis. Three studies examined or reported on an association between hearing loss and the quality of physician-patient communication. One study included an intervention to temporarily mitigate hearing loss to improve communication. Less than one-quarter of studies of physician-elderly patient communication even mention that hearing loss may affect communication. Methodologically, this means that many studies may have omitted an important potential confounder. Perhaps more importantly, research in this field has largely overlooked a highly prevalent, important, and remediable influence on the quality of communication.

Background: The National Committee for Quality Assurance (NCQA) developed the Healthcare Effectiveness Data and Information Set (HEDIS) performance measures to evaluate health plan performance against benchmarks or other plans. The Center for Medicare and Medicaid Services (CMS) requires insurance plans to submit HEDIS data to qualify as a Medicare Advantage Plan (MAP) or a MAP that includes Medicare Part D (MAPD). Our MAPD selected and tested HEDIS and other 5-Star measures comparing the quality of care for MAPD members who did and did not use a Geriatric Assessment Center (GAC) serving MAPD members within a markedly impoverished region in the western US. Members visit the GAC typically once per year. Methods: We selected eight measures reflecting preventive care, chronic disease management, and continuity of care (See Table). Within one Medical Group, we compared the performance of these measures for Plan Members having attended the GAC in 2014 with Plan members who did not but had at least one primary care provider (PCP) visit. We used exact match procedures to identify a comparison group based on age, gender, Low-Income Subsidy Level, Risk Adjustment Factor and Special Needs Plan. Results: We identified 258 members who used the GAC in 2014 and 258 as the matched control group (See Table). Preventive care but not chronic disease management performance measures were significantly better for members who used the GAC. GAC users had better care continuity performance (measured by readmission rates) but this was not statistically significant. Conclusions: The GAC is well suited to achieving high quality preventive care due to the ease of completion in one visit. Chronic disease management care continuity is likely better suited to a repeated visit care structure. (Table Presented)

Background: A comprehensive geriatric assessment clinic (GAC) was established in collaboration with a health plan within a markedly impoverished region in the US. Evaluation objectives were to assess the quality of chronic illness care from the perspective of member-patients and providers. Methods: We abstracted medical records of patients attending the GAC during one quarter of 2014 and administered the 20-item Patient Assessment of Chronic Illness Care (PACIC) survey in English and Spanish in 2015. We anonymously surveyed patients before and directly after visits. Survey questions, modified for low health literacy, used a 1-to-5-likert scale (1=none of the time to 5=always) for 5 domains: patient activation, decision support, goal setting, problem solving, and care coordination. We administered a 7-item quality assessment survey to providers for: relevance, ease of use, ability to apply findings, and agreement with diagnostic findings and recommendations, using a 1-to-5-likert scale (1=strongly disagree to 5=strongly agree). Results: Abstracted data for 193 patients demonstrated 51% had not finished high school and their chronic condition burden was high (mean: 7.2 conditions; 31% with diabetes). For patient surveys (n=165; 19% Spanish), post-visit PACIC domain scores ranged from 4.0-4.5 and post-visit ratings were higher across all domains (1.4 to 1.7 higher; p<0.001 for each). For each of 20 questions, aggregate post scores improved, indicating higher quality. For provider surveys, respondents (n=14) felt the GAC provided useful (50%) and relevant (64%) information for their practices, taught them how to provide better care for other patients (64%), and made it easier to provide care (50%). Less than one third (29%) felt their experience discouraged them from using the service again. Discussion: The AC greatly improved member-perceived care quality and facilitated provider care among patients with high chronic condition burden, suggesting a useful strategy for patients with high need. Since some providers did not find this service useful, provider focus groups are underway to understand and improve unmet provider needs

Limbic encephalitis presents as altered mood, memory loss and confusion. Clinical features may include psychiatric symptoms and seizures. In contrast to paraneoplastic disorders, non-paraneoplastic autoimmune encephalitis often responds to immunotherapy and sometimes with marked recovery. However, relapse can occur. An 82-year-old male presented with subacute episodes of memory loss over a few days. The patient was unable to recognize his own home and family members. Physical exam was unremarkable. Neuropsychological assessment revealed deficits in cognitive performance that could be consistent with moderate dementia or a more rapidly progressive encephalopathy. Agitated behavior and anxiety were also noted. Laboratory evaluation included hyponatremia, which was corrected with no symptom improvement. B12, TSH, and HIV were normal. CSF analysis revealed 10 WBCs/muL, Glucose-52 mg/dl, Protein-62 mg/dl and was negative for infectious, neoplastic causes, varicella, VDRL, viral cultures, NMDA receptor antibody, GAD 65 antibody and Anti-Hu antibody. Occult malignancy work up with CT scan of chest and abdomen and colonoscopy was normal. Serum for voltage-gated potassium channel antibodies was positive at 849 pmol/l (>88). EEG showed occasional focal left fronto-temporal slowing without epileptiform activity. MRI revealed focal enhancement of the medial left temporal lobe consistent with limbic encephalitis. The patient started high dose steroids with improvement in memory and complete resolution of focal abnormality within the left hippocampal/parahippocampal region suggestive of resolving encephalitis. At seven months after tapering steroids the patient presented with myoclonus and recurrent memory loss. MRI demonstrated recurrent encephalitis with gyral swelling and FLAIR hyperintensity in the left temporal lobe. The patient was restarted on high dose steroids with addition of Rituximab. This case illustrates that limbic encephalitis can present as a rapidly progressive dementia. Differential diagnosis should include more unusual forms of rapidly progressive dementia such as Jakob-Creutzfeldt disease if myoclonus is present, Lewy body dementia if waxing and waning memory, and Alzheimer's dementia with acute delirium if presenting over a period of months. In this patient, MRI changes were crucial to recognizing a potentially reversible limbic encephalitis. Early recognition and treatment may decrease relapse and reduce functional impairment

Objective: 1) To demonstrate the feasibility of an interdisciplinary home visit program (HVP) for advanced Parkinson's disease (PD) providing expert, interdisciplinary care directly to homebound patients; 2) to test whether the HVP improves patient quality of life despite disease progression. Background: As PD progresses, symptoms increase, quality of life declines, and individuals may become homebound, often losing access to neurologic care. This leads to a surge in emergency department visits and hospitalizations. Improving access to expert in-home care may improve quality of life. Design/Methods: PD patients meeting Medicare criteria for homebound status are eligible to receive quarterly home visits over 12 months. Each visit entails an evaluation by a movement disorders specialist, social worker, and nurse, including detailed history, physical examination, real-time medication reconciliation, psychosocial evaluation, and referral to in-home services. Quality of life (Neuro-QoL) is measured at Visits 1 and 4. Results: Out of 27 subjects enrolled, 26 have completed the study. At baseline, subjects' mean age is 81 years (SD 7.8); mean PD duration is 10 years; mean UPDRS total score is 65 (SD 20). Of the 26 subjects completing Visit 4, total UPDRS increased by a mean of 12 (SD 10.7), yet quality of life improved in 7/8 Neuro-QoL domains. Conclusions: We identified a unique population typically lost to clinical care and research-the elderly, homebound with advanced PD-and this is the first description of their progression over time. Despite the expected progression of functional and motor disability over one year, subjects reported improved quality of life since entering the HVP. Next steps include the implementation of a hybrid in-person/telehealth home visit model, inclusion of individuals with cognitive impairment in future studies, and comparison of outcomes with other advanced PD populations

This study attempted to better understand factors associated with relationship conflict between daughters and their parents with dementia. We examined data from 77 daughters self-identified as primary caregivers of a parent with dementia to test the hypothesis that daughters' belief that a parent with dementia can control their symptoms is associated with more conflict, defined as high expressed emotion (EE). Participants completed self-report questionnaires assessing beliefs about parents' ability to control symptoms, stress, relationship conflict, parent agitation, and cognitive status. Results indicated that greater intensity of daughters' belief that their parent can control dementia-related symptoms was associated with more relationship conflict or "high EE" (beta = 0.57, P < .001). Daughters' beliefs about parental behavior may contribute to caregiver stress and exacerbate negative behaviors exhibited by individuals with dementia. Educating caregivers about parental behaviors and examining factors underlying caregiver interpretations of these behaviors hold promise for reducing caregiver stress.

INTRODUCTION/BACKGROUND:Individuals with amnestic mild cognitive impairment (aMCI) are at elevated risk of developing Alzheimer's disease (AD) dementia. METHODS:With data from the Aging, Demographics, and Memory Study, we used the Clinical Dementia Rating Sum of Boxes classifications to conduct a cross-sectional analysis assessing the relationship between cognitive state and various direct and indirect costs and health care utilization patterns. RESULTS:Patients with aMCI had less medical expenditures than patients with moderate and severe AD dementia (P < .001) and were also significantly less likely to have been hospitalized (P = .04) and admitted to nursing home (P < .001). Compared to individuals with normal cognition, patients with aMCI had significantly less household income (P = .018). DISCUSSION/CONCLUSIONS:Patients with aMCI had lower medical expenditures than patients with AD dementia. Poor cognitive status was linearly associated with lower household income, higher medical expenditures, higher likelihood of nursing and home care services, and lower likelihood of outpatient visits.

As many as 50% of people satisfying diagnostic criteria for dementia are undiagnosed. A team-based training program for dementia screening and management was developed targeting four professions (medicine, nursing, pharmacy, social work) whose scope of practice involves dementia care. An interprofessional group of 10 faculty members was trained to facilitate four interactive competency stations on dementia screening, differential diagnoses, dementia management and team care planning, and screening for and managing caregiver stress. Registrants were organized into teams of five members, with at least one member of each profession per team. The teams rotated through all stations, completing assigned tasks through interprofessional collaboration. A total of 117 professionals (51 physicians, 11 nurses, 20 pharmacists, 24 social workers, 11 others) successfully completed the program. Change scores showed significant improvements in overall competence in dementia assessment and intervention (very low = 1; very high = 5; average change 1.12, P < .001), awareness of importance of dementia screening (average change 0.85, P < .001), and confidence in managing medication (average change 0.86, P < .001). Eighty-seven participants (82.9%) reported feeling confident or very confident using the dementia toolkit at their home institution. In a survey administered 3 months after the session, 48 respondents reported that they had changed their approach to administering the Mini-Cog test (78%), differential diagnosis (49%), assessment of caregiver stress (74%), and accessing community support and services (69%). In conclusion, team-based interprofessional competency training is a team teaching model that can be used to enhance competency in dementia screening and management in medical, nursing, pharmacy, and social work practitioners.
