Trends in observation stays for Medicare beneficiaries with and without Alzheimer's disease and related dementias.

BACKGROUND: There has been a marked rise in the use of observation care for Medicare beneficiaries visiting the emergency department (ED) in recent years. Whether trends in observation use differ for people with Alzheimer's disease and Alzheimer's disease-related dementias (AD/ADRD) is unknown. METHODS: Using a national 20% sample of Medicare beneficiaries ages 68+ from 2012 to 2018, we compared trends in ED visits and observation stays by AD/ADRD status for beneficiaries visiting the ED. We then examined the degree to which trends differed by nursing home (NH) residency status, assigning beneficiaries to four groups: AD/ADRD residing in NH (AD/ADRD+ NH+), AD/ADRD not residing in NH (AD/ADRD+ NH-), no AD/ADRD residing in NH (AD/ADRD- NH+), and no AD/ADRD not residing in NH (AD/ADRD- NH-). RESULTS: Of 7,489,780 unique beneficiaries, 18.6% had an AD/ADRD diagnosis. Beneficiaries with AD/ADRD had more than double the number of ED visits per 1000 in all years compared to those without AD/ADRD and saw a faster adjusted increase over time (+26.7 vs. +8.2 visits/year; p < 0.001 for interaction). The annual increase in the adjusted proportion of ED visits ending in observation was also greater among people with AD/ADRD (+0.78%/year, 95% CI 0.77-0.80%) compared to those without AD/ADRD (+0.63%/year, 95% CI 0.59-0.66%; p < 0.001 for interaction). Observation utilization was greatest for the AD/ADRD+ NH+ population and lowest for the AD/ADRD- NH- population, but the AD/ADRD+ NH- group saw the greatest increase in observation stays over time (+15.4 stays per 1000 people per year, 95% CI 15.0-15.7). CONCLUSIONS: Medicare beneficiaries with AD/ADRD have seen a disproportionate increase in observation utilization in recent years, driven by both an increase in ED visits and an increase in the proportion of ED visits ending in observation.

Factors associated with disagreement between clinician app-based ultra-brief Confusion Assessment Method and reference standard delirium assessments.

BACKGROUND: Recently, the Ultra-Brief Confusion Assessment Method (UB-CAM), designed to help physicians and nurses to recognize delirium, showed high, but imperfect, accuracy compared with Research Reference Standard Delirium Assessments (RRSDAs). The aim of this study is to identify factors associated with disagreement between clinicians' app-based UB-CAM assessments and RRSDAs. METHODS: This is a secondary analysis of a prospective diagnostic test study. The study was conducted at two hospitals and included 527 inpatients (≥70 years old) and 289 clinicians (53 physicians, 236 nurses). Trained research associates performed RRSDAs and determined delirium presence using the CAM. Clinicians administered the UB-CAM using an iPad app. Disagreement factors considered were clinician, patient, and delirium characteristics. We report odds ratios and 95% confidence intervals. RESULTS: One thousand seven hundred and ninety-five clinician UB-CAM assessments paired with RRSDAs were administered. The prevalence of delirium was 17%. The rate of disagreement between clinician UB-CAM assessments and RRSDAs was 12%. Significant factors associated with disagreement between clinician UB-CAM assessments and RRSDAs (OR [95% CI]) included: presence of dementia (2.7 [1.8-4.1]), patient education high school or less (1.9 [1.3-2.9]), psychomotor retardation (2.5 [1.4-4.2]), and the presence of mild delirium or subsyndromal delirium (5.5 [3.5-8.7]). Significant risk factors for false negatives were patient age less than 80 (2.2 [1.1-4.3]) and mild delirium (3.5 [1.6-7.4]). Significant risk factors for false positives were presence of dementia (4.0 [2.3-7.0]), subsyndromal delirium (5.1 [2.9-9.1]), and patient education high school or less (2.0 [1.2-3.6]). Clinician characteristics were not significantly associated with disagreement. CONCLUSIONS: The strongest factors associated with disagreement between clinician UB-CAM screens and RRSDAs were the presence of dementia and subsyndromal delirium as risk factors for false positives, and mild delirium and younger age as a risk factor for false negatives. These disagreement factors contrast with previous studies of risk factors for incorrect clinician delirium screening, and better align screening results with patient outcomes.

Home-Based Care Provider Perspectives on Care Refusal During the COVID-19 Pandemic.

Acute and chronic disease management continues to shift toward a health care in the home model, yet literature discussing continuity of home-based care services during public health emergencies, such as infectious disease pandemics, is scant. In the current study, we used semi-structured telephone interviews with 27 home-based care providers (HBCPs) from Medicare-certified home health care agencies located in eight U.S. counties to explore older adults' decision making around home-based care service continuation during the coronavirus disease 2019 (COVID-19) pandemic. Four themes emerged, including two related to older adults' decision making around refusal of in-home care and two related to HBCPs' responses to care refusals. Fear of COVID-19 infection motivated older adults to make care-related decisions that were incongruent with their health needs, including refusal of care in the home, despite receiving education from HBCPs. These data highlight a need for tools to help HBCPs better support patients through decision-making processes about care continuation during COVID-19 and future infectious disease pandemics.

Collaborating toward equity in Pennsylvania: The Age-Friendly Care, PA project.

OBJECTIVE: To collaboratively implement the age-friendly health systems framework, known as the 4Ms: What Matters, Medication, Mentation, and Mobility, at The Primary Health Network (PHN), a federally qualified health center. DATA SOURCES: Data were collected from PHN electronic medical records (EMRs) for individuals over age 65 from December 30, 2019 to December 24, 2021 and from Project ECHO© attendance and evaluation surveys. STUDY DESIGN: The telementoring educational program, Project ECHO©, was used to engage PHN health care professionals working in rural areas of Pennsylvania to incorporate the 4Ms into their practice starting with the annual wellness visit (AWV). Project ECHO© was launched at three primary care sites. After 18 months, it was then disseminated to an additional 18 sites creating pilot and comparison groups. Outcomes included codesigned patient process metrics using EMR data and project ECHO© participant data. DATA COLLECTION METHODS: EMR data were generated by system reports created by PHN's quality assurance program manager. Project ECHO© data were collected and managed using REDCap electronic data capture tools. Outcomes were aggregated, analyzed for trends over time, and compared between groups. PRINCIPAL FINDINGS: All nine process outcomes increased from baseline to follow-up at the three initial sites, ranging from 4% to 43% g. At year two, the three initial sites had higher rates on AWVs (pilot 24%, comparison 12%; p < 0.0001), Advance Care Planning (New on file, pilot 8%, comparison 2%; Discussed with patient, pilot 18%, comparison 13%; Patient declined, pilot 0%, comparison 0%; p = 0.0001), Dementia Screening (pilot 24%, comparison 12%; p < 0.0001), Fall Risk Management (pilot 43%, comparison 10%; p < 0.0001), and Mobility Goal (pilot 19%, comparison 9%; p < 0.0001); and lower rates on High-Risk Medication Elimination (pilot 54%, comparison, 63%, p < 0.02). CONCLUSIONS: Access to high-quality geriatric care for rural older adults can be improved by increasing health care professionals' knowledge of the 4Ms, beginning with its incorporation into the AWV.

The Association Between Preference Satisfaction and Satisfaction with Overall Care for Nursing Home Residents.

The Centers for Medicare and Medicaid Services mandate the provision of person-centered care (PCC), but there is limited evidence on how PCC impacts nursing home (NH) residents' care experiences. This study examined the relationship between n = 163 NH residents' ratings of satisfaction with care related to their preferences and their satisfaction with overall care. Residents with higher preference satisfaction ratings reported significantly higher levels of satisfaction with overall care. Using preference satisfaction ratings has the potential to improve PCC planning and delivery in nursing homes.

Comparative salary-related costs of a brief app-directed delirium identification protocol by hospitalists, nurses, and nursing assistants.

BACKGROUND: Systematic screening can improve delirium identification among hospitalized older adults. Prior studies have shown clinicians and health system leaders may believe they do not have the time and resources for assessment. We conducted a comparative salary-related cost analysis of an adaptive delirium identification protocol directed by an iPad app. METHODS: We recruited 527 older adult medicine patients from an urban academic medical center (n = 269) and a rural community hospital (n = 258). Physicians and nurses completed the two-step Ultra-brief Confusion Assessment Method (UB-CAM) protocol (with or without a skip pattern), while certified nursing assistants completed only the UB-2 ultra-brief screen. The sample included 527 patients (average age 80, 57% women, 35% with dementia). Time required to administer the protocol was collected automatically by the iPad app. Salary-related costs of screening were determined by multiplying the time required by the hourly wage for the three disciplines, as obtained from national and regional published healthcare salary cost data. Cost estimates for entire hospital implementation were also calculated. RESULTS: Participants were screened on 924 hospital days by 399 clinicians (53 physicians, 236 nurses, 110 CNAs). For the UB-2, CNAs cost per screen was lower than the other clinician types ($0.37 per screen vs. $0.73 for nurses and $2.39 for hospitalists). For the UB-CAM with skip (UB-CAM), costs per protocol were $1.10 for nurses vs. $3.61 for physicians. The annual salary-related costs of hospital-wide implementation of a nurse-based UB-CAM protocol in a medium-sized (300-bed) hospital was $63,015 plus $4356 for initial and annual training. CONCLUSIONS: CNAs and nurses had the lowest salary-associated costs for app-directed CAM-based delirium screening and identification, respectively. Salary-related annual hospital costs for the most efficient protocols in a medium-sized hospital were less than the annual cost of hiring 1 FTE of the discipline performing the protocols.

Psychoactive medication therapy and delirium screening in skilled nursing facilities.

BACKGROUND: A positive delirium screen at skilled-nursing facility (SNF) admission can trigger a simultaneous diagnosis of Alzheimer's Disease or related dementia (AD/ADRD) and lead to psychoactive medication treatment despite a lack of evidence supporting use. METHODS: This was a nationwide historical cohort study of 849,086 Medicare enrollees from 2011-2013 who were admitted to the SNF from a hospital without a history of dementia. Delirium was determined through positive Confusion Assessment Method screen and incident AD/ADRD through active diagnosis or claims. Cox proportional hazard models predicted the risk of receiving one of three psychoactive medications (i.e., antipsychotics, benzodiazepines, antiepileptics) within 7 days of SNF admission and within the entire SNF stay. RESULTS: Of 849,086 newly-admitted SNF patients (62.6% female, mean age 78), 6.1% had delirium (of which 35.4% received an incident diagnosis of AD/ADRD); 12.6% received antipsychotics, 30.4% benzodiazepines, and 5.8% antiepileptics. Within 7 days of admission, patients with delirium and incident dementia were more likely to receive an antipsychotic (relative risk [RR] 3.09; 95% confidence interval [CI] 2.99 to 3.20), or a benzodiazepine (RR 1.23; 95% CI 1.19 to 1.27) than patients without either condition. By the end of the SNF stay, patients with both delirium and incident dementia were more likely to receive an antipsychotic (RR 3.04; 95% CI 2.95 to 3.14) and benzodiazepine (RR 1.32; 95% CI 1.29 to 1.36) than patients without either condition. CONCLUSION: In this historical cohort, a positive delirium screen was associated with a higher risk of receiving psychoactive medication within 7 days of SNF admission, particularly in patients with an incident AD/ADRD diagnosis. Future research should examine strategies to reduce inappropriate psychoactive medication prescribing in older adults admitted with delirium to SNFs.

Actualizing Better Health And Health Care For Older Adults.

By 2030 more people in the United States will be older than age sixty-five than younger than age five. Our health care system is unprepared for the complexity of caring for a heterogenous population of older adults-a problem that has been magnified by the coronavirus disease 2019 (COVID-19) pandemic. Here, as part of the National Academy of Medicine's Vital Directions for Health and Health Care: Priorities for 2021 initiative, we identify six vital directions to improve the care and quality of life for all older Americans. The next administration must create an adequately prepared workforce; strengthen the role of public health; remediate disparities and inequities; develop, evaluate, and implement new approaches to care delivery; allocate resources to achieve patient-centered care and outcomes, including palliative and end-of-life care; and redesign the structure and financing of long-term services and supports. If these priorities are addressed proactively, an infrastructure can be created that promotes better health and equitable, goal-directed care that recognizes the preferences and needs of older adults.

Association of Positive Delirium Screening with Incident Dementia in Skilled Nursing Facilities.

BACKGROUND AND OBJECTIVE: Early detection of delirium in skilled nursing facilities (SNFs) is a priority. The extent to which delirium screening leads to a potentially inappropriate diagnosis of Alzheimer's disease and related dementia (ADRD) is unknown. DESIGN: Nationwide retrospective cohort study from 2011 to 2013. SETTING: An SNF. PARTICIPANTS: A total of 1,175,550 Medicare enrollees who entered the SNF from a hospital and had no prior diagnosis of dementia. EXPOSURE: A positive screen for delirium using the validated Confusion Assessment Method (CAM), performed as part of the federally mandated Minimum Data Set (MDS) assessment. MEASUREMENTS: Incident all-cause dementia, ascertained through International Classification of Diseases, Ninth Revision (ICD-9), diagnosis in Medicare claims or active diagnoses in MDS. RESULTS: Positive screening for delirium was identified in 7.7% of cases (n = 90,449), and most occurred within the first 7 days of SNF admission (62.5%). The overall incidence of ADRD was 6.3% (n = 73,542). Nearly all new diagnoses of ADRD (93.5%) occurred within the first 30 days of SNF admission. Patients who screened CAM positive for delirium had a nearly threefold increased risk of receiving an incident ADRD diagnosis on the same day (hazard ratio (HR) = 2.63; 95% confidence interval (CI) = 1.50-4.63). Among patients who screened CAM positive for delirium, those who were cognitively intact or had mild cognitive impairments were, on average, six times more likely to receive an incident ADRD diagnosis (HR = 6.64; 95% CI = 1.76-25.0) relative to those testing CAM negative. CONCLUSION AND RELEVANCE: Among older adults not previously diagnosed with dementia, a positive screen for delirium was significantly associated with higher risk of ADRD diagnosis after admission to a SNF. This risk was highest for patients in the first days of their stay and with the least cognitive impairment, suggesting that the ADRD diagnosis was potentially inappropriate.

Understanding and improving value frameworks with real-world patient outcomes.

OBJECTIVES: To provide recommendations that will improve approaches to measuring the value of new medical technologies to patients. STUDY DESIGN: Informed discussion by experts after literature review. METHODS: A working group was formed, and participants discussed how value frameworks should incorporate key features important to patients in evaluating new medical technologies, particularly for chronic diseases. RESULTS: The working group suggests that new value frameworks should integrate real-world evidence to complement randomized controlled trials, incorporate the ways in which real-world behavior mediates outcomes, and explicitly discuss how therapies affect real-world equity and disparities in care. CONCLUSIONS: Collective stakeholders that include key decision makers within our healthcare system need to recognize the importance of implementing real-world evidence and devote resources to further research into the chronic disease areas in which the impact of human behavior is amplified by the duration of disease and treatment.

Derivation and Validation of a Severity Scoring Method for the 3-Minute Diagnostic Interview for Confusion Assessment Method--Defined Delirium.

OBJECTIVES: To derive and validate a method for scoring delirium severity using a recently validated, brief, structured diagnostic interview for Confusion Assessment Method (CAM)-defined delirium (3D-CAM) and to demonstrate its agreement with the CAM Severity short form (CAM-S SF) as the reference standard. DESIGN: Derivation and validation analysis in a prospective cohort study. SETTING: Two academic medical centers. PARTICIPANTS: Individuals aged 70 and older enrolled in the Successful Aging after Elective Surgery Study undergoing major elective noncardiac surgery (N = 566). MEASUREMENTS: The sample was randomly divided into a derivation dataset (n = 377) and an independent validation dataset (n = 189). These datasets were used to develop a severity scoring method using the 3D-CAM based on the four-item CAM-S SF (3D-CAM-S) and evaluate agreement between the 3D-CAM-S and the traditional CAM-S SF using weighted kappa statistics. RESULTS: A method for scoring severity using 3D-CAM items was developed that achieved good agreement with the CAM-S SF in the derivation dataset (κ = 0.94, 95% confidence interval (CI) = 0.93-0.95). The 3D-CAM-S achieved nearly identical agreement in the independent validation dataset (κ = 0.93, 95% CI = 0.92-0.95), and 100% of 3D-CAM-S scores were within 1 point of the CAM-S SF score in both datasets. The 3D-CAM-S also strongly predicts clinical outcomes. CONCLUSION: A newly developed method for scoring delirium severity using the 3D-CAM (the 3D-CAM-S) has excellent agreement with the CAM-S SF. This new methodology enables clinicians and researchers using the 3D-CAM for surveillance to measure delirium severity and monitor its course simultaneously by tracking changes over time. The 3D-CAM-S expands the utility of the 3D-CAM as an important tool for delirium recognition and management.

Screening for delirium using family caregivers: convergent validity of the Family Confusion Assessment Method and interviewer-rated Confusion Assessment Method.

OBJECTIVES: To explore agreement between the Family Confusion Assessment Method (FAM-CAM) for delirium identification and interviewer-rated CAM delirium ratings. DESIGN: Exploratory analysis of agreement. SETTING: Community. PARTICIPANTS: Fifty-two family caregivers and 52 elderly adults with preexisting impairment according to standardized cognitive testing. MEASUREMENTS: The interviewer-rating for delirium was determined by fulfillment of the CAM algorithm RESULTS: The total sample included 52 paired CAM:FAM-CAM assessments completed across 52 dyads of elderly adults with preexisting cognitive impairment and family caregivers. The point prevalence of delirium was 13% (7/52). Characteristics did not differ significantly between the groups with and without delirium. The FAM-CAM questions that mapped directly to the original four-item CAM algorithm had the best overall agreement with the interviewer-rated CAM (kappa = 0.85, 95% confidence interval (CI) = 0.65-1.0), sensitivity of 88% (95% CI = 47-99%), and specificity of 98% (95% CI = 86-100%). CONCLUSION: The FAM-CAM is a sensitive screening tool for detection of delirium in elderly adults with cognitive impairment using family caregivers, with relevance for research and clinical practice.

It's about time: use of nonpharmacological interventions in the nursing home.

PURPOSE: To provide a stronger evidence base for cultural change in the nursing home, this study elicited nursing, recreational therapy, and medical staff perceptions of barriers to the implementation of nonpharmacological interventions for the behavioral and psychological symptoms of dementia (BPSD). DESIGN: Thirty-five staff members (registered nurses, licensed practical nurses, nurses' aides, recreational therapists, activity personnel, and medical directors) from six nursing homes located in Pennsylvania and North Carolina participated in the qualitative study. METHODS: A focus group methodology was used to capture discussions that were audio-recorded and transcribed verbatim. Data were analyzed using standard methods of content and thematic analysis. FINDINGS: Four broad themes were identified: the changing landscape; resident behaviors; reaching out to the person with dementia; and the educational needs of staff. The concept of time emerged as a key barrier to the use of nonpharmacological interventions for BPSD. CONCLUSIONS: Successful use of nonpharmacological interventions requires the right staff with the right education at the right time. The Vulnerability Framework is a model that helped organize these findings into a meaningful perspective. CLINICAL RELEVANCE: To effect change in the nursing home, the findings indicate a need for: implementation of staffing patterns that allow staff the time to make a difference in the care of residents with BPSD; development of educational programs that promote staff understanding versus control; and design of research studies that answer questions about the influence of time on the selection of interventions for BPSD.

Delirium superimposed on dementia. Assessment and intervention.

Delirium remains a significant risk for hospitalized older adults and has been shown to be a persistent risk posthospitalization as well. Dementia is a risk factor for delirium. The prevalence of delirium superimposed on dementia (DSD) ranges from 22% to 89% in hospitalized and community-dwelling individuals 65 and older. Individuals with DSD have been found to have accelerated decline in cognitive and functional abilities, greater need for institutionalization, greater rehospitalization risk, and increased mortality. The purpose of this article is to define and describe DSD, outline assessment tools for its identification, and provide appropriate nursing interventions.

Cognitive training for early-stage Alzheimer's disease and dementia.

The purpose of this article is to critically review and synthesize the literature on the effects of nonpharmacological cognitive training on dementia symptoms in early-stage Alzheimer's disease (AD) and related dementia. Electronic databases MEDLINE (PubMed), CINAHL, PsycInfo, and the Cochrane Library were searched using the keywords cognition, reality orientation, Alzheimer's disease, psychosocial factors, cognitive therapy, brain plasticity, enriched environments, and memory training. The findings support that cognitive training improves cognition, activities of daily living, and decision making. Interventions are more effective if they are structured and focus on specific known losses related to the AD pathological process and a person's residual ability, or are combined with cognitive-enhancing medications. Nursing implications are also discussed.

Medication use after bariatric surgery in a managed care cohort.

BACKGROUND: Bariatric surgery has been shown to provide long-term weight loss, in addition to a significant reduction in obesity-related co-morbidities. The primary aim of this study was to describe the medication use and costs within a managed care cohort after bariatric surgery. A secondary aim was to describe the use rates for other health services after bariatric surgery. METHODS: This retrospective cohort study used an administrative database from a large managed care organization to examine the health outcomes in persons 6 months before and 6 months after bariatric surgery. RESULTS: The average number of prescription claims per person decreased after surgery, from 6.93 (SD 7.16) before to 4.88 (SD 5.84) after surgery (P <.001). The average number of claims for office visits decreased from 5.52 before to 3.94 after surgery (P = .0028), and the average number of claims for outpatient visits decreased from 0.75 before to 0.40 after surgery (P <.001). However, the average number of inpatient visit claims increased after bariatric surgery, from 0.04 (SD 0.31) to 0.07 (SD 0.52) claims per person (P = .04). In the preoperative period, the paid costs for pharmacy claims were an average of $221.30 (SD $341.25). After surgery, the pharmacy paid costs decreased to an average cost of $158.90 (SD $454.13). CONCLUSION: Within this sample, medication use and costs decreased within 6 months of bariatric surgery. Decreases were also noted in the postoperative period in several obesity-related co-morbidities, office visits, emergency room visits, and outpatient visits; however, an increase occurred in inpatient stays after surgery.

Health outcomes associated with potentially inappropriate medication use in older adults.

The purpose of this study was to examine the prevalence of potentially inappropriate medication use (PIMs) among community-dwelling older adults and the association between PIMs and health care outcomes. Participants were 17,971 individuals age 65 years and older. PIM use was defined by the Beers criteria. Drug-related problems (DRPs) were defined using ICD-9 codes. Forty percent of the 17,971 individuals filled at least 1 PIM prescription, and 13% filled 2 or more PIM prescriptions. Overall DRP prevalence among those with at least 1 PIM prescription was 14.3% compared to 4.7% in the non-PIM group (p < .001). In conclusion, preventing PIM use may be important for decreasing medication-related problems, which are increasingly being recognized as requiring an integrated interdisciplinary approach.
