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

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.

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.

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.

Objective: 1) To describe the role of social workers in managing the care coordination of homebound patients with advanced Parkinson's disease (PD); 2) to demonstrate whether social workers increase access to needed services and 3); to determine whether multiple visits have added value. Background: As PD progresses, the burden of motor and nonmotor symptoms as well as other comorbidities increases, eventually leading to a homebound state. Patients lose access to many essential services, resulting in reduced quality of life, hospitalization, and greater care partner burden. Homebound patients are eligible to participate in the Interdisciplinary Home Visit Program (HVP) at the Fresco Institute for Parkinson's and Movement Disorders. Visits include cross-discipline evaluations. The social worker's role is to identify unmet needs, provide diagnosis-specific education, counsel the patient and care partner, provide crucial resource referral, and coordinate care following each visit to ensure patients are connected to services. The value of multiple visits is unknown. Methods: We examined social work effort and dyad need by the number and type of referrals delivered through the HVP caring for the first 26 enrolled patients. We collected data across multiple visits to determine the value of repeat visits. "Referrals" here are defined as a successful connection to a referred service. Results: We observed a mean referral rate of 2.69 for the first visit. Although referral numbers decreased at each visit, the need for new referrals continued to be identified (0.5 referrals at the fourth visit). Referrals were diverse in type but specific types were frequent across patients: physical therapy - 73%; speech therapy - 58%; psychotherapy - 54%; home safety assessment - 27%; and psychiatry - 15%. Other referrals included support group, visiting primary care physician, medical alert system, home health care, elder care attorneys, and assistive devices. Conclusions: Homebound patients with advanced PD are in need of a variety of referrals to improve care. Through repeated social work assessments, new needs continue to be identified. Follow up home visits provide the social worker with the opportunity to facilitate continued assessment, connections to new resources, reinforce previously identified unmet needs, and provide supportive counseling that adapts to the patient and family's evolving circumstances as PD progresses

Background: Medication errors including non-adherence are independently associated with increased morbidity and mortality in the elderly population. In the USA, medication errors are estimated to increase healthcare costs by over $170 billion annually. In Parkinson's disease (PD) specifically, medication non-adherence directly increases disability and healthcare costs. When PD progresses and patients become homebound, office-based medication reconciliation is not possible and errors may go undetected. Objectives: To examine the number and types of medication errors detected by a registered nurse during interdisciplinary home visits for patients with advanced PD. Methods: We defined medication discrepancy errors as errors of dose, frequency, strength, omission, and commission. We compared provider-documented prescriptions with the patient- or caregiver- administered regimen for 26 subjects completing at least one home visit (and up to 4) during a one-year period of quarterly home visits. Results: Among 26 subjects, 11 subjects (42.3%) had completed four visits. In total, 54 errors were detected across 78 visits (0.69 detected errors per visit), with a median of 1 error per subject (range 0-9). The most common types of detected errors were errors of commission (35%) in which the subject was taking a medication not known to the provider or which they were instructed to discontinue, followed by errors of frequency (28%) and omission (24%). Conclusion: Medication errors are frequent among advanced PD patients and are ongoing even with medication reconciliation efforts. To our knowledge, this is the first study documenting the prevalence of medication errors in homebound patients with advanced PD and supports the value of a home visit program in advanced PD. This abstract has previously been presented at the 20th International Congress of Parkinson's and Movement Disorders on June 20th, 2016

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 lose access to neurologic care, becoming homebound. This leads to a surge in emergency department visits and hospitalizations. Improving access to expert in-home care may improve quality of life and minimize acute healthcare utilization. Methods: PD patients treated at The Fresco Institute for Parkinson's and Movement Disorders who meet Medicare criteria for homebound status are eligible to receive four quarterly home visits over 12 months. Each visit entails an evaluation by a movement disorders specialist, social worker, and nurse, including detailed history of symptoms, falls, and healthcare utilization; physical examination including the UPDRS; medication reconciliation; psychosocial evaluation and follow-up; and referral to in-home services. Quality of life (Neuro-QoL) is measured at Visits 1 and 4. Results: We have enrolled 26 subjects to date; 65% have completed 3 and 38% have completed 4 visits. At baseline, subjects' mean age is 81 years (SD 8); mean PD duration is 10 years (SD 6); mean UPDRS total score is 65 (SD 20, range 35-107). In the 12 months prior to enrollment, 48% had been hospitalized; 40% had visited an ED. Of the 10 subjects completing Visit 4, total UPDRS increased by a mean of 13 (SD 9), yet quality of life improved in 9/9 Neuro-QoL domains. Preliminary analysis of the first 74 visits shows no change in the rate of acute healthcare utilization between the 12 months preceding and time since HVP entry (p=0.59). Conclusions: Despite the expected progression of functional and motor disability over one year, subjects report improved quality of life since entering the HVP. No difference in acute healthcare utilization has yet been observed. We are in the process of assessing medication errors, adherence, and caregiver strain in this understudied population, with the aim of expanding the HVP as a novel model of care in the future. Previously Presented: The design and interim analysis of the HVP model was previously presented at the International Congress of Parkinson's and Movement Disorders 2015 and 2016, respectively

Objective: To determine the prevalence of low health literacy among caregivers of community-dwelling individuals with Parkinson's Disease (PD). Background: Low health literacy (HL) indicates a limited ability to understand and apply basic information to make appropriate healthcare decisions. Previously, we reported that nearly 30% of non-demented, community-dwelling individuals with PD had low HL, which was associated with both increased caregiver burden and hospitalization rates. The HL of caregivers, however, has only begun to be explored in other, non-PD cohorts, and is disheartening. In PD particularly, caregivers with adequate HL may serve as a safety net for vulnerable patients, assisting with medication adherence and health-related activities. Design/Methods: Cross-sectional study of caregivers of communitydwelling individuals with PD at two urban, academic referral centers. Individuals presenting for a clinical visit for PD were asked to participate in a study of HL and medication beliefs, and if available, self-identifying caregivers were asked to participate. Both patients and caregivers completed brief demographic questionnaires as well as the Newest Vital Sign, a validated 6-item screening instrument for HL, where 0-3 points indicates low HL and 4-6 points indicates adequate HL. Results: 103 patient-caregiver dyads participated. Caregivers had a mean age of 65 (SD 9), 72% had a college degree or higher, and 72% were women. Paid caregivers constituted less than 2% of our sample. Low HL was detected in 23% of patients and 14% of caregivers, respectively, with low concordance between pairs (agreement 73%, kappa=0.1, p=0.1). There was no significant association between level of education and HL in either patients or caregivers. Among patients with low HL (n=24), 21% also had a caregiver with low HL. Conclusion: Low HL is common in this sample of PD caregivers and patients despite high levels of education. In order to best educate and address the concerns of PD patients and families, we must recognize the prevalence and consequences of low HL. (Figure presented)
