Relationship of POLST to Hospitalization and ICU Care Among Nursing Home Residents in California.

BACKGROUND: Physician Orders for Life Sustaining Treatment (POLST) document instructions for intensity of care based upon patient care preferences. POLST forms generally reflect patients' wishes and dictate subsequent medical care, but it is not known how POLST use and content among nursing home residents is associated with inpatient utilization across a large population. OBJECTIVE: Evaluate the relationship between POLST use and content with hospital utilization among nursing home residents in California. DESIGN: Retrospective cohort study using the Minimum Data Set linked to California Section S (POLST documentation), the Medicare Beneficiary Summary File, and Medicare line item claims. PATIENTS: California nursing home residents with Medicare fee-for-service insurance, 2011-2016. MAIN MEASURES: Hospitalization, days in the hospital, and days in the intensive care unit (ICU) after adjustment for resident and nursing home characteristics. KEY RESULTS: The 1,112,834 residents had a completed and signed (valid) POLST containing orders for CPR with Full treatment 29.6% of resident-time (in person-years) and a DNR order with Selective treatment or Comfort care 27.1% of resident-time. Unsigned POLSTs accounted for 11.3% of resident-time. Residents experienced 14 hospitalizations and a mean of 120 hospital days and 37 ICU days per 100 person-years. Residents with a POLST indicating CPR Full treatment had utilization nearly identical to residents without a POLST. A gradient of decreased utilization was related to lower intensity of care orders. Compared to residents without a POLST, residents with a POLST indicating DNR Comfort care spent 56 fewer days in the hospital and 22 fewer days in the ICU per 100 person-years. Unsigned POLST had a weaker and less consistent relationship with hospital utilization. CONCLUSIONS: Among California NH residents, there is a direct relationship between intensity of care preferences in POLST and hospital utilization. These findings emphasize the importance of a valid POLST capturing informed preferences for nursing home residents.

Training Community Health Workers to Address Disparities in Dementia Care: A Case Study From Oklahoma With National Implications.

The projected increase of dementia in the diverse aging US population calls for a well-prepared public health workforce. Community health workers (CHWs) can address dementia in culturally appropriate ways. Collaborating with stakeholders, we developed a train-the-trainer curriculum for CHWs and used a virtual training platform to test its feasibility with 77 CHWs. Pre-/post-evaluation data demonstrated modestly increased dementia knowledge scores. Training participants valued the resources shared and interacting with peers. Disseminating this training could contribute to closing gaps in dementia care in diverse communities, along with policies supporting CHWs as a workforce that reduces age-related disparities and promotes health equity.

Care preferences in physician orders for life sustaining treatment in California nursing homes.

BACKGROUND: Physician Orders for Life-Sustaining Treatment (POLST) facilitates documentation and transition of patients' life-sustaining treatment orders across care settings. Little is known about patient and facility factors related to care preferences within POLST across a large, diverse nursing home population. We describe the orders within POLST among all nursing home (NH) residents in California from 2011 to 2016. METHODS: California requires NHs to document in the Minimum Data Set whether residents complete a POLST and orders within POLST. Using a serial cross-sectional design for each year, we describe POLST completion and orders for all California NH residents from 2011 to 2016 (N = 1,112,668). We used logistic mixed-effects regression models to estimate POLST completion and resuscitation orders to understand the relationship with resident and facility characteristics, including Centers for Medicare and Medicaid Services (CMS) Nursing Home Compare overall five-star quality rating. RESULTS: POLST completion significantly increased from 2011 to 2016 with most residents having a POLST in 2016 (short-stay:68%; long-stay:81%). Among those with a POLST in 2016, 54% of long-stay and 41% of short-stay residents had a DNR order. Among residents with DNR, >90% had orders for limited medical interventions or comfort measures. Few residents (<6%) had a POLST with contradictory orders. In regression analyses, POLST completion was greater among residents with more functional dependence, but was lower among those with more cognitive impairment. Greater functional and cognitive impairment were associated with DNR orders. Racial and ethnic minorities indicated more aggressive care preferences. Higher CMS five-star facility quality rating was associated with greater POLST completion. CONCLUSIONS: Six years after a state mandate to document POLST completion in NHs, most California NH residents have a POLST, and about half of long-stay residents have orders to limit life-sustaining treatment. Future work should focus on determining the quality of care preference decisions documented in POLST.

Utility of a short, telephone-administered version of the Montreal Cognitive Assessment.

BACKGROUND: Because of the COVID-19 pandemic, the ongoing D-CARE pragmatic trial of two models of dementia care management needed to transition to all data collection by telephone. METHODS: For the first 1069 D-CARE participants, we determined the feasibility of administering a short 3-item version of the Montreal Cognitive Assessment (MoCA) to persons with dementia by telephone and examined the correlation with the full 12-item version. RESULTS: The 3-item version could be administered by telephone in approximately 6 min and was highly correlated with the full MoCA (r = 0.78, p < 0.0001). CONCLUSIONS: This brief version of the MoCA was feasible to collect by telephone and could be used as an alternative to the full MoCA, particularly if the purpose of cognitive assessment is characterization of study participants.

Standardised approach to measuring goal-based outcomes among older disabled adults: results from a multisite pilot.

BACKGROUND: Older adults with complex care needs face trade-offs in determining the right course of treatment. The Centers for Medicare and Medicaid Services identified 'Care is personalized and aligned with patient's goals' as a key meaningful measures category, yet existing quality measures typically assess disease-specific care and may not effectively evaluate what is most important to older adults and family members. Measures based on individualised goals and goal-based outcomes have been proposed as an alternative but are not routinely assessed or implemented. OBJECTIVES: We tested two approaches to assessing goal-based outcomes that allow individuals to set goals based on their own priorities and measure progress-(1) goal attainment scaling and (2) existing, validated patient-reported outcome measures (PROM). METHODS: A prospective cohort study of feasibility in seven sites (33 clinicians) of the two approaches with 229 individuals. We calculated performance on a measure of achievement of individually identified goals. RESULTS: Both approaches were successfully implemented in a non-randomly selected population, and a goal-based outcome could be calculated for 189 (82%) of participants. Most individuals met their goal-based outcome (73%) with no statistical difference between the goal attainment scaling approach (74%) and the patient-reported outcomes approach (70%). Goals were heterogeneous ranging from participating in activities, health management, independence and physical health. Clinicians chose to use goal attainment scaling (n=184, 80%) more often than PROMs (n=49, 20%) and rated the goal attainment scaling approach as useful for providing patient care. CONCLUSION: Goal-based outcomes have the potential to both improve the way healthcare is provided and fill a critical gap in value-based payment.

Validation of a Brief Multi-Dimensional Assessment of Dementia Severity.

BACKGROUND/OBJECTIVES: Briefer measures of symptoms and functional limitations may reduce assessment burden and facilitate monitoring populations of persons with dementia (PWD). DESIGN: Prospective follow-up study. SETTING: University-based dementia care management program. PARTICIPANTS: 1,091 PWD. MEASUREMENTS: We assessed cognition (Mini Mental State Examination (MMSE)-11 tasks), neuropsychiatric symptom severity (Neuropsychiatric Inventory Questionnaire Severity Scale (NPIQ-S)-12 items), and functional ability (Activities of Daily Living (ADL)-6 items; Functional Activities Questionnaire (FAQ)-10 items). Item response theory was used to select subsets of items by identifying low item discrimination (<1.50), poor item fit (χ2 ), local dependence (LD), and with difficulty similar to other items. We estimated correlations between original and shorter scales and compared their associations with mortality. We added two symptoms (trouble swallowing, coughing when eating) reflecting late-stage dementia complications, created a multi-dimensional dementia assessment composite, and examined its association with mortality. RESULTS: Five MMSE tasks were eliminated: two with low discrimination, two with difficulty similar to other items, and one with poor fit. The remaining tasks were correlated with the full MMSE at r = 0.82. We retained three ADLs that were correlated with the total ADL set at r = 0.95 and kept five FAQ items that were not LD (correlation with full FAQ, r = 0.97). Associations with mortality were similar between the longer and shorter scales. A higher score on the composite (range 0-100) indicates worse dementia impact and was associated with mortality (hazard ratio (HR) per scale point: 1.03 (1.02-1.04)). CONCLUSION: These brief assessments and dementia composite may reduce administration time while preserving validity.

Recommendations to Improve Payment Policies for Comprehensive Dementia Care.

Access to comprehensive dementia care is limited. Recent changes in billing for professional services, including new physician fee schedule codes, encourage clinicians to provide new services; however, current reimbursement does not cover costs for all needed elements of dementia care. The Payment Model for Comprehensive Dementia Care Conference convened more than 50 national experts from diverse perspectives to review promising strategies for payment reform including ways to accelerate their adoption. Recommendations for reform included payments for services to family caregivers; new research to determine success metrics; education for consumers, providers, and policymakers; and advancing a population health model approach to tier coverage based on risk and need within a health system.

D-CARE: The Dementia Care Study: Design of a Pragmatic Trial of the Effectiveness and Cost Effectiveness of Health System-Based Versus Community-Based Dementia Care Versus Usual Dementia Care.

BACKGROUND/OBJECTIVES: Although several approaches have been developed to provide comprehensive care for persons living with dementia (PWD) and their family or friend caregivers, the relative effectiveness and cost effectiveness of community-based dementia care (CBDC) versus health system-based dementia care (CBDC) and the effectiveness of both approaches compared with usual care (UC) are unknown. DESIGN: Pragmatic randomized three-arm superiority trial. The unit of randomization is the PWD/caregiver dyad. SETTING: Four clinical trial sites (CTSs) based in academic and clinical health systems. PARTICIPANTS: A total of 2,150 English- or Spanish-speaking PWD who are not receiving hospice or residing in a nursing home and their caregivers. INTERVENTIONS: Eighteen months of (1) HSDC provided by a nurse practitioner or physician's assistant dementia care specialist who works within the health system, or (2) CBDC provided by a social worker or nurse care consultant who works at a community-based organization, or (3) UC with as needed referral to the Alzheimer's Association Helpline. MEASUREMENTS: Primary outcomes: PWD behavioral symptoms and caregiver distress as measured by the Neuropsychiatric Inventory Questionnaire (NPI-Q) Severity and Modified Caregiver Strain Index scales. SECONDARY OUTCOMES: NPI-Q Distress, caregiver unmet needs and confidence, and caregiver depressive symptoms. Tertiary outcomes: PWD long-term nursing home placement rates, caregiver-reported PWD functional status, cognition, goal attainment, "time spent at home," Dementia Burden Scale-Caregiver, a composite measure of clinical benefit, Quality of Life of persons with dementia, Positive Aspects of Caregiving, and cost effectiveness using intervention costs and Medicare claims. RESULTS: The results will be reported in the spring of 2024. CONCLUSION: D-CARE will address whether emphasis on clinical support and tighter integration with other medical services has greater benefit than emphasis on social support that is tied more closely to community resources. It will also assess the effectiveness of both interventions compared with UC and will evaluate the cost effectiveness of each intervention.

Health Care Utilization and Cost Outcomes of a Comprehensive Dementia Care Program for Medicare Beneficiaries.

Importance: An estimated 4 to 5 million Americans have Alzheimer disease or another dementia. Objective: To determine the health care utilization and cost outcomes of a comprehensive dementia care program for Medicare fee-for-service beneficiaries. Design, Setting, and Participants: In this case-control study, we used a quasiexperimental design to compare health care utilization and costs for 1083 Medicare fee-for-service beneficiaries enrolled in the University of California Los Angeles Health System Alzheimer and Dementia Care program between July 1, 2012, and December 31, 2015, with those of 2166 similar patients with dementia not participating in the program. Patients in the comparison cohort were selected using the zip code of residence as a sampling frame and matched with propensity scores, which included demographic characteristics, comorbidities, and prior-year health care utilization. We used Medicare claims data to compare utilization and cost outcomes for the 2 groups. Interventions: Patients in the dementia care program were comanaged by nurse practitioners and physicians, and the program consisted of structured needs assessments of patients and their caregivers, creation and implementation of individualized dementia care plans with input from primary care physicians, monitoring and revising care plans, referral to community organizations for dementia-related services and support, and access to a clinician for assistance and advice 24 hours per day, 7 days per week. Main Outcomes and Measures: Admissions to long-term care facilities; average difference-in-differences per quarter over the 3-year intervention period for all-cause hospitalization, emergency department visits, 30-day hospital readmissions, and total Medicare Parts A and B costs of care. Program costs were included in the cost estimates. Results: Program participants (n = 382 men, n = 701 women; mean [SD] age, 82.10 [7.90] years; age range 54-101 years) were less likely to be admitted to a long-term care facility (hazard ratio, 0.60; 95% CI, 0.59-0.61) than those not participating in the dementia care program (n = 759 men, n = 1407 women; mean [SD] age, 82.42 [8.50] years; age range, 34-103 years). There were no differences between groups in terms of hospitalizations, emergency department visits, or 30-day readmissions. The total cost of care to Medicare, excluding program costs, was $601 less per patient per quarter (95% CI, -$1198 to -$5). After accounting for the estimated program costs of $317 per patient per quarter, the program was cost neutral for Medicare, with an estimated net cost of -$284 (95% CI, -$881 to $312) per program participant per quarter. Conclusions and Relevance: Comprehensive dementia care may reduce the number of admissions to long-term care facilities, and depending on program costs, may be cost neutral or cost saving. Wider implementation of such programs may help people with dementia stay in their communities.

A Composite Measure of Caregiver Burden in Dementia: The Dementia Burden Scale-Caregiver.

OBJECTIVES: To better capture the scope of caregiver burden by creating a composite of 3 existing measures that assess different health domains. DESIGN: Prospective follow-up study. SETTING: University-based dementia care management program. PARTICIPANTS: Caregivers of persons with dementia (PWD) (N=1,091). MEASUREMENTS: The composite measure (the Dementia Burden Scale-Caregiver (DBS-CG)) was based on the Modified Caregiver Strain Index, Neuropsychiatric Inventory Questionnaire Distress Scale, and Patient Health Questionnaire (PHQ-9). Alternative factor structures were evaluated using 2 confirmatory factor analysis (CFA) models: a bifactor model and a 3 correlated factors model. Good model fit was defined as a root mean square error of approximation (RMSEA) of less than 0.06 and comparative fit index (CFI) value greater than 0.95. Coefficient omega was used to estimate scale reliability. Minimally important differences (MIDs) were estimated by anchoring the magnitude of DBS-CG change to change in caregiver self-efficacy and functional ability of PWD. RESULTS: The bifactor CFA model fit best (RMSEA = 0.04, CFI = 0.95). Based on this model, a DBS-CG scale was created wherein all items were transformed to a possible range of 0 to 100 and then averaged. Higher scores indicate higher burden. Mean DBS-CG score was 27.3. The reliability was excellent (coefficient omega=0.93). MID estimates ranged from 4 to 5 points (effect sizes: 0.20-0.49). CONCLUSION: This study provides support for the reliability and validity of the DBS-CG. It can be used as an outcome measure to assess the effect of interventions to reduce dementia caregiver burden.

Development of an algorithm to identify fall-related injuries and costs in Medicare data.

BACKGROUND: Identifying fall-related injuries and costs using healthcare claims data is cost-effective and easier to implement than using medical records or patient self-report to track falls. We developed a comprehensive four-step algorithm for identifying episodes of care for fall-related injuries and associated costs, using fee-for-service Medicare and Medicare Advantage health plan claims data for 2,011 patients from 5 medical groups between 2005 and 2009. METHODS: First, as a preparatory step, we identified care received in acute inpatient and skilled nursing facility settings, in addition to emergency department visits. Second, based on diagnosis and procedure codes, we identified all fall-related claim records. Third, with these records, we identified six types of encounters for fall-related injuries, with different levels of injury and care. In the final step, we used these encounters to identify episodes of care for fall-related injuries. RESULTS: To illustrate the algorithm, we present a representative example of a fall episode and examine descriptive statistics of injuries and costs for such episodes. Altogether, we found that the results support the use of our algorithm for identifying episodes of care for fall-related injuries. When we decomposed an episode, we found that the details present a realistic and coherent story of fall-related injuries and healthcare services. Variation of episode characteristics across medical groups supported the use of a complex algorithm approach, and descriptive statistics on the proportion, duration, and cost of episodes by healthcare services and injuries verified that our results are consistent with other studies. CONCLUSIONS: This algorithm can be used to identify and analyze various types of fall-related outcomes including episodes of care, injuries, and associated costs. Furthermore, the algorithm can be applied and adopted in other fall-related studies with relative ease.

Unmet needs of caregivers of individuals referred to a dementia care program.

OBJECTIVES: To characterize caregiver strain, depressive symptoms, and self-efficacy for managing dementia-related problems and the relationship between these and referring provider type. DESIGN: Cross-sectional observational cohort. SETTING: Urban academic medical center. PARTICIPANTS: Caregivers of community-dwelling adults with dementia referred to a dementia care management program. MEASUREMENTS: Caregivers were surveyed and completed the Patient Health Questionnaire (PHQ-9) about themselves; the Modified Caregiver Strain Index; the Neuropsychiatric Inventory Questionnaire, which measures patient symptom severity and related caregiver distress; and a nine-item caregiver self-efficacy scale developed for the study. RESULTS: Of 307 patient-caregiver dyads surveyed over a 1-year period, 32% of caregivers reported confidence in managing dementia-related problems, 19% knew how to access community services to help provide care, and 28% agreed that the individual's provider helped them work through dementia care problems. Thirty-eight percent reported high levels of caregiver strain, and 15% reported moderate to severe depressive symptoms. Caregivers of individuals referred by geriatricians more often reported having a healthcare professional to help work through dementia care problems than those referred by internists, family physicians, or other specialists, but self-efficacy did not differ. Low caregiver self-efficacy was associated with higher caregiver strain, more caregiver depressive symptoms, and caring for an individual with more-severe behavioral symptoms. CONCLUSION: Most caregivers perceived inadequate support from the individual's provider in managing dementia-related problems, reported strain, and had low confidence in managing caregiving. New models of care are needed to address the complex care needs of individuals with dementia and their caregivers.
