Dementia Severity Associated With Increased Risk of Potentially Preventable Readmissions During Home Health Care

Home Health Care and Place of Death in Medicare Beneficiaries With and Without Dementia

BACKGROUND AND OBJECTIVES

Home health care supports patient goals for aging in place. Our objective was to determine if home health care use in the last 3 years of life reduces the risk of inpatient death without hospice.

RESEARCH DESIGN AND METHODS

We analyzed the characteristics of 2,065,300 Medicare beneficiaries who died in 2019 and conducted multinomial logistic regression analyses to evaluate the association between the use and timing of home health care, dementia diagnosis, and place of death.

RESULTS

Receiving any home health care in the last 3 years of life was associated with a lower probability of inpatient death without hospice (Pr 23.3% vs 31.5%, p < .001), and this effect was stronger when home health care began prior to versus during the last year of life (Pr 22.5% vs 24.3%, p < .001). Among all decedents, the probability of death at home with hospice compared to inpatient death with hospice was greater when any home health care was used (Pr 46.0% vs 36.5%, p < .001), and this association was strongest among beneficiaries with dementia who started home health care at least 1 year prior to death (Pr 55.6%, p < .001).

DISCUSSION AND IMPLICATIONS

Use of home health care during the last 3 years of life was associated with reduced rates of inpatient death without hospice, and increased rates of home death with hospice. Increasing affordable access to home health care can positively affect end-of-life care outcomes for older Americans and their family caregivers, especially those with dementia.

Skilled home healthcare utilization and outcomes for older adults with dementia: A scoping review

OBJECTIVES

This study aims to summarize the existing research literature examining Medicare-skilled home health (HH) utilization and clinical outcomes for persons with dementia (PwD). We sought to answer the following questions: (1) How is dementia defined and classified in the HH literature? (2) What associations have been observed between dementia status and patterns of HH utilization? (3) What associations have been observed between dementia status and HH outcomes?

METHODS

Using Arksey and O'Malley's framework for scoping reviews, we searched PubMed, Google Scholar, and select relevant journals for quantitative studies conducted in the United States between 2000 and 2023 examining Medicare HH use and outcomes for PwD. We describe and compare approaches to classify dementia, identify findings related to HH utilization and outcomes supported by the preponderance of evidence, and comment on existing gaps and areas of ambiguity in the literature.

RESULTS

Thirty-two articles met the inclusion criteria. Most used claims-based data to classify dementia, leveraged national data, and were limited to traditional Medicare beneficiaries. Studies found meaningful differences in HH utilization by dementia status; most notably, PwD were more likely to access HH without a preceding hospitalization, had longer lengths of stay, and incurred higher HH costs. Literature relating to clinical outcomes was more difficult to interpret, due to significant variation in study objectives, samples, and outcome measures which prompted more nuanced and even contradictory conclusions. There is a dearth of research identifying how specific HH care pathways (e.g., service types, visit frequency) impact outcomes for this patient population.

CONCLUSIONS

This review supports the understanding that PwD are a unique subpopulation of HH patients who require special attention in policy development and evaluation. Critical research is needed to examine clinical outcomes in PwD further to inform practice and improve care quality.

Patterns of national emergency department utilization by fee-for-service Medicare beneficiaries with dementia

BACKGROUND

Individuals with Alzheimer's disease and related dementias (ADRD) often face high acute care clinical utilization and costs with unclear benefits in survival or quality of life. The emergency department (ED) is frequently the site of pivotal decisions in these acute care episodes. This study uses national Medicare data to explore this population's ED utilization.

METHODS

Retrospective cohort study of persons aged ≥66 years enrolled in traditional Medicare with a Chronic Condition Warehouse diagnosis of dementia. Primary 1-year outcome measures included ED visits with and without hospitalization, ED visits per 100 days alive, and health-care costs. A multivariate random effects regression model (clustered by county of residence), adjusted for sociodemographics and comorbidities, examined how place of care on January 1, 2018, was associated with subsequent ED utilization.

RESULTS

In 2018, 2,680,006 ADRD traditional Medicare patients (mean age 82.9, 64.2% female, 9.4% Black, 6.2% Hispanic) experienced a total of 3,234,767 ED visits. Over half (52.2%) of the cohort experienced one ED visit, 15.5% experienced three or more, and 37.1% of ED visits resulted in hospitalization. Compared with ADRD patients residing at home without services, the marginal difference in ED visits per 100 days alive varied by location of care. Highest differences were observed for those with hospitalizations (0.48 visits per 100 days alive, 95% confidence interval [CI] 0.47-0.49), skilled nursing facility (rehab/skilled nursing facility [SNF]) stays (0.27, 95% CI 0.27-0.28), home health stays (0.25, 95% CI 0.25-0.26), or observation stays (0.82, 95% CI 0.77-0.87). Similar patterns were observed with ED use without hospitalization and health-care costs.

CONCLUSIONS

Persons with ADRD frequently use the ED-particularly those with recent hospitalizations, rehab/SNF stays, or home health use-and may benefit from targeted interventions during or before the ED encounters to reduce avoidable utilization and ensure goal-concordant care.

Validation of Claims-Based Frailty Index for Identifying Moderate-to-Severe Dementia in Medicare Beneficiaries

OBJECTIVE

Previous research using the National Health and Aging Trends Study showed that a claims-based frailty index (CFI) could be useful for identifying moderate-to-severe dementia in Medicare claims data. This study aims to validate the findings in an independent cohort.

DESIGN

Retrospective cohort study.

SETTING AND PARTICIPANTS

The study included 658 fee-for-service beneficiaries with dementia who participated in the 2016-2020 Medicare Current Beneficiary Survey in the community-dwelling.

METHODS

We operationalized the Functional Assessment Staging Test (FAST) scale (range: 1-7, stages 5-7 indicate moderate-to-severe dementia) using survey information. CFI (range: 0-1, higher scores indicate greater frailty) was calculated using Medicare claims 12 months before the participants' interview date. Using the previously proposed cut point of 0.280, we calculated sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for identifying moderate-to-severe dementia. Survey procedures were used to account for survey design and weighted to reflect national estimates.

RESULTS

The population had a mean age (SD) of 80.7 (8.9) years, 58.5% female, and 101 beneficiaries (14.8%) had moderate-to-severe dementia. The CFI cut point of 0.280 demonstrated sensitivity 0.49 (95% CI, 0.38-0.59), specificity 0.80 (0.77-0.84), PPV 0.30 (0.23-0.38), and NPV 0.90 (0.87-0.93). Compared with those with a CFI <0.280, beneficiaries with a CFI ≥0.280 had an elevated risk of mortality (2.9% vs 4.1%) over 1 year.

CONCLUSIONS AND IMPLICATIONS

These results confirm our previous findings that CFI among beneficiaries with a dementia diagnosis is a useful measure of moderate-to-severe dementia for Medicare claims data.

The Role of Neighborhood Socioeconomic Status in Institutionalization of Home Health Care Patients With and Without Alzheimer's Disease and Related Dementias

OBJECTIVES

To assess whether neighborhood socioeconomic status (SES) moderates the association between Alzheimer's disease and related dementias (ADRD) and successful discharge to the community. In addition, to explore whether the role of neighborhood SES on successful discharge for patients with ADRD varies by the severity of ADRD.

DESIGN

This is a retrospective cohort study.

SETTING AND PARTICIPANTS

Medicare Fee-for-service beneficiaries, aged 65 or older, who received home health care in 2019.

METHODS

We used linear probability regression models with successful discharge to the community as the main outcome, and neighborhood SES and ADRD as independent variables. Also, we modified the Functional Assessment Staging Tool (FAST) to measure ADRD severity.

RESULTS

Our study results show ADRD and residing in neighborhoods with lower socioeconomic conditions were independently associated with lower probabilities of successful discharge to the community. We also found that the differences in probabilities of remaining at home between patients with and without ADRD were larger among those in neighborhoods with lower SES (ADRD∗less disadvantaged neighborhood, coeff: -0.01, P < .001; ADRD∗more disadvantaged neighborhood, coeff: -0.02, P < .001; ADRD∗most disadvantaged neighborhood, coeff: 0.032, P < .001). Among patients with ADRD, patients with the most advanced ADRD were less likely to remain in their homes and community when living in neighborhoods with lower SES.

CONCLUSIONS AND IMPLICATIONS

Our study results show that when patients with ADRD receiving home health care live in neighborhoods with lower SES, they face further challenges to remaining in their homes and community. Public health officials and community planners should consider using area-level interventions to improve care and health outcomes for patients with ADRD. Also, further research aimed at identifying the specific factors and resources influencing lower care quality and poorer health outcomes in socioeconomically disadvantaged neighborhoods, particularly for patients with ADRD, can provide valuable insights for the development and implementation of targeted interventions.

Dementia severity at incident diagnosis in a population representative sample of older Americans

INTRODUCTION

We provide the first analysis of distribution of dementia severity at incident diagnosis for a population representative sample of older Americans.

METHODS

Using data from the Aging, Demographics, and Memory Study (ADAMS), the Health Retirement Study (HRS), and traditional Medicare claims, we estimated the Clinical Dementia Rating Scale for ADAMS respondents and applied parameter estimates to predict dementia severity for HRS respondents with claims-based incident dementia diagnosis.

RESULTS

Seventy percent of older adults received a dementia diagnosis of mild cognitive impairment or mild dementia (early stages). Fewer individuals were diagnosed at early stages in years 2000 to 2008 (65%) compared to years 2009 to 2016 (76%). About 72% of non-Hispanic white persons were diagnosed at early stages, compared to 63% non-Hispanic black and 59% Hispanic persons. More males than females were diagnosed at early stages (75% vs 67%).

DISCUSSION

These data linkages allow population surveillance of early and equitable dementia detection in the older US population to assess clinical and policy levers to improve detection.

Highlights

For the US population 70 and older, 30% were diagnosed with dementia at a moderate or severe stage.Fewer were diagnosed at early stages in years 2000 to 2008 compared to 2009 to 2016 (65% vs 76%).A total of 72% of white persons were diagnosed at early stages, compared to 63% black and 59% Hispanic persons.More males than females were diagnosed at early stages (75% vs 67%).High wealth and education level were associated with diagnosis at early stages disease.

Teamwork and Nurse Care Coordination in Home Healthcare

Home healthcare agencies provide interdisciplinary care to millions of individuals annually. Care is typically led by registered nurses who often determine additional disciplines need to be included in the plan of care. We found that, although persons living with dementia represent about 30% of the home healthcare population, data from our home healthcare system showed that over a 1-year period with 36,443 home care episodes, only 29.6% had one or more social worker visits. Recognizing Alzheimer's disease-related dementia as a terminal condition and shifting toward a palliative care approach can be a challenge in home healthcare where care is focused on restorative care or rehabilitative goals with a primary focus on improvement in condition. The goal of this article is to present insights into nurse-led care coordination and teamwork and provide implications for practice.

Successful Discharge to Community From Home Health Less Likely for People in Late Stages of Dementia

BACKGROUND AND PURPOSE

Several studies have established the efficacy of home health in meeting the health care needs of people with Alzheimer disease and related dementias (ADRD) and helping them to remain at home. However, transitioning to the community after discharge from home health presents challenges to patient safety and quality of life. The severity of an individual's functional impairments, cognitive limitations, and behavioral and psychological symptoms may compound these challenges. The purpose of this study was to examine the association between dementia severity and successful discharge to community (DTC) from home health.

METHODS

This was a retrospective study of 142 376 Medicare beneficiaries with ADRD. Successful DTC was defined as having no unplanned hospitalization or death within 30 days of DTC from home health. Successful DTC rates were calculated, and multilevel logistic regression was used to estimate the relative risk (RR) of successful DTC, by dementia severity category, adjusted for patient and clinical characteristics. Six dementia severity categories were identified using a crosswalk between items on the Outcome and Assessment Information Set and the Functional Assessment Staging Tool.

RESULTS AND DISCUSSION

Successful DTC occurred in 71.2% of beneficiaries. Beneficiaries in the 2 most severe dementia categories had significantly lower risk of successful DTC (category 6: RR = 0.90, 95% CI = 0.889-0.910; category 7: RR = 0.737, 95% CI = 0.704-0.770) than those in the least severe dementia category. The RR of successful DTC for people with ADRD decreased as the level of independence with oral medication management decreased and when there was an overall greater need for caregiver assistance.

CONCLUSIONS

Patient status at the time of admission to home health is associated with outcomes after discharge from home health. Early identification of people in advanced stages of ADRD provides an opportunity to implement strategies to facilitate successful DTC while people are still receiving home care services. The severity of ADRD and availability of caregiver assistance should be key considerations in planning for successful DTC for people with ADRD.

Variation in Home Healthcare Use by Dementia Status Among a National Cohort of Older Adults

BACKGROUND

Medicare-funded home healthcare (HHC) delivers skilled nursing, therapy, and related services through visits to the patient's home. Nearly one-third (31%) of HHC patients have diagnosed dementia, but little is currently known regarding how HHC utilization and care delivery differ for persons living with dementia (PLwD).

METHODS

We drew on linked 2012-2018 Health and Retirement Study and Medicare claims for a national cohort of 1 940 community-living older adults. We described differences in HHC admission, length of stay, and referral source by patient dementia status and used weighted, multivariable logistic and negative binomial models to estimate the relationship between dementia and HHC visit type and intensity while adjusting for sociodemographic characteristics, health and functional status, and geographic/community factors.

RESULTS

PLwD had twice the odds of using HHC during a 2-year observation period, compared to those without dementia (odds ratio [OR]: 2.03; p < .001). They were more likely to be referred to HHC without a preceding hospitalization (49.4% vs 32.1%; p < .001) and incurred a greater number of HHC episodes (1.4 vs 1.0; p < .001) and a longer median HHC length of stay (55.8 days vs 40.0 days; p < .001). Among post-acute HHC patients, PLwD had twice the odds of receiving social work services (unadjusted odds ratio [aOR]: 2.15; p = .008) and 3 times the odds of receiving speech-language pathology services (aOR: 2.92; p = .002).

CONCLUSIONS

Findings highlight HHC's importance as a care setting for community-living PLwD and indicate the need to identify care delivery patterns associated with positive outcomes for PLwD and design tailored HHC clinical pathways for this patient subpopulation.

Association of functional and cognitive impairment severity with discharge to long-term care facilities in older patients admitted to a general acute care hospital from home

BACKGROUND

The early recognition of hospitalized patients at risk of being discharged to long-term care facilities (LTCFs) may help to identify those who require transitional care programs and interventions that support discharge to home. We examined the association of functional and cognitive impairment severity with discharge to LTCFs among older hospitalized patients.

METHODS

In this retrospective cohort study, we used an administrative claims database linked with geriatric assessment data from a general acute care hospital in Japan. We analyzed patients aged ≥65 years discharged between July 2016 and December 2018. The severity of functional and cognitive impairments was assessed using the Dementia Assessment Sheet for Community-based Integrated Care System 8-items (DASC-8) scale. Based on their DASC-8 scores, patients were designated as Category I (no impairment), Category Ⅱ (mild impairment), or Category III (moderate/severe impairment). We conducted logistic regression analyses to examine the association between the severity of impairments and discharge to LTCFs after adjusting for patient-level factors.

RESULTS

We analyzed 9,060 patients (mean age: 79.4 years). Among the 112 patients (1.2%) discharged to LTCFs, 62.3%, 18.6%, and 19.2% fell under Category I, Category Ⅱ, and Category III, respectively. Category II was not significantly associated with discharge to LTCFs. However, Category III had a significantly higher odds of discharge to LTCFs than Category I (Adjusted odds ratio: 2.812, 95% confidence interval: 1.452-5.449).

CONCLUSION

Patients identified as Category III by the DASC-8 on admission may benefit from enhanced transitional care and interventions that promote discharge to home.

Claims-Based Frailty Index as a Measure of Dementia Severity in Medicare Claims Data

BACKGROUND

Dementia severity is unavailable in administrative claims data. We examined whether a claims-based frailty index (CFI) can measure dementia severity in Medicare claims.

METHODS

This cross-sectional study included the National Health and Aging Trends Study Round 5 participants with possible or probable dementia whose Medicare claims were available. We estimated the Functional Assessment Staging Test (FAST) scale (range: 3 [mild cognitive impairment] to 7 [severe dementia]) using information from the survey. We calculated CFI (range: 0-1, higher scores indicating greater frailty) using Medicare claims 12 months prior to the participants' interview date. We examined C-statistics to evaluate the ability of the CFI in identifying moderate-to-severe dementia (FAST stage 5-7) and determined the optimal CFI cut-point that maximized both sensitivity and specificity.

RESULTS

Of the 814 participants with possible or probable dementia and measurable CFI, 686 (72.2%) patients were ≥75 years old, 448 (50.8%) were female, and 244 (25.9%) had FAST stage 5-7. The C-statistic of CFI to identify FAST stage 5-7 was 0.78 (95% confidence interval: 0.72-0.83), with a CFI cut-point of 0.280, achieving the maximum sensitivity of 76.9% and specificity of 62.8%. Participants with CFI ≥0.280 had a higher prevalence of disability (19.4% vs 58.3%) and dementia medication use (6.0% vs 22.8%) and higher risk of mortality (10.7% vs 26.3%) and nursing home admission (4.5% vs 10.6%) over 2 years than those with CFI <0.280.

CONCLUSIONS

Our study suggests that CFI can be useful in identifying moderate-to-severe dementia from administrative claims among older adults with dementia.

Identifying Medicare beneficiaries with Alzheimer's disease and related dementia using home health OASIS assessments

BACKGROUND

Home health services are an important site of care following hospitalization among Medicare beneficiaries, providing health assessments that can be leveraged to detect diagnoses that are not available in other data sources. In this work, we aimed to develop a parsimonious and accurate algorithm using home health outcome and assessment information set (OASIS) measures to identify Medicare beneficiaries with a diagnosis of Alzheimer's disease and related dementia (ADRD).

METHODS

We conducted a retrospective cohort study of Medicare beneficiaries with a complete OASIS start of care assessment in 2014, 2016, 2018, or 2019 to determine how well the items from various versions could identify those with an ADRD diagnosis by the assessment date. The prediction model was developed iteratively, comparing the performance of different models in terms of sensitivity, specificity, and accuracy of prediction, from a multivariable logistic regression model using clinically relevant variables, to regression models with all available variables and predictive modeling techniques, to estimate the best performing parsimonious model.

RESULTS

The most important predictors of having a diagnosis of ADRD by the start of care OASIS assessment were a prior discharge diagnosis of ADRD among those admitted from an inpatient setting, and frequently exhibiting symptoms of confusion. Results from the parsimonious model were consistent across the four annual cohorts and OASIS versions with high specificity (above 96%), but poor sensitivity (below 58%). The positive predictive value was high, over 87% across study years.

CONCLUSIONS

The proposed algorithm has high accuracy, requires a single OASIS assessment, is easy to implement without sophisticated statistical models, and can be used across four OASIS versions and in situations where claims are not available to identify individuals with a diagnosis of ADRD, including the growing population of Medicare Advantage beneficiaries.

Caregivers’ experience with Tele-Savvy Caregiver Program post-hospitalization

Despite the frequent hospitalizations and readmissions of persons living with dementia (PLWD), no telehealth transitional care interventions focus on PLWDs' unpaid caregivers. Tele-Savvy Caregiver Program is a 43-day evidence-based online psychoeducational intervention for PLWDs' caregivers. The aim of this formative evaluation was to explore caregivers' acceptability of and experience with their participation in Tele-Savvy after their PLWDs' hospital discharge. Additionally, we gathered caregivers' feedback on the recommended features of a transitional care intervention, suitable for caregivers' schedule and needs post-discharge. Fifteen caregivers completed the interviews. Data were analyzed via conventional content analysis. Four categories were identified: (1) Tele-Savvy improved participants' understanding of dementia and caregiving; (2) hospitalization started a "new level of normal"; (3) PLWDs' health concerns; and (4) transitional care intervention development. Participation in Tele-Savvy was acceptable for most caregivers. Participants' feedback provides content and structural guidance for the development of a new transitional care intervention for PLWDs' caregivers.

Cognitive impairment associated with greater care intensity during home health care

BACKGROUND

In Medicare-funded home health care (HHC), one in three patients has cognitive impairment (CI), but little is known about the care intensity they receive in this setting. Recent HHC reimbursement changes fail to adjust for patient CI, potentially creating a financial disincentive to caring for these individuals.

METHODS

This cohort study included a nationally representative sample of 1214 Medicare HHC patients between 2011 and 2016. Multivariable logistic and negative binomial regressions modelled the relationship between patient CI and care intensity-measured as the number and type of visits received during HHC and likelihood of receiving multiple successive HHC episodes.

RESULTS

Patients with CI had 45% (P < .05) greater odds of receiving multiple successive HHC episodes and received an additional 2.82 total (P < .001), 1.39 nursing (P = .003), 0.72 physical therapy (P = .03), and 0.60 occupational therapy visits (P = .01) during the index HHC episode.

DISCUSSION

Recent HHC reimbursement changes do not reflect the more intensive care needs of patients with CI.

Unmet Caregiving Needs Among Sepsis Survivors Receiving Home Health Care: The Need for Caregiver Training

Unmet needs for family caregiver assistance threaten patient outcomes during Medicare home health care (HHC). Sepsis survivors represent a growing proportion of the HHC patient population, but little is known regarding their risk for unmet caregiving needs. We describe prevalence and underlying cause of unmet caregiving needs for sepsis survivors receiving HHC, using HHC patient assessment data for 85,851 older sepsis survivors receiving post-acute HHC in 2013-2014. Unmet caregiving needs were most common for assistance with Activities of Daily Living (ADLs) (28%) and medication administration (27%). Caregivers' need for training accounted for more than three-fourths of all unmet caregiving needs. Those who experienced decline/no improvement in cognitive function were more likely to experience unmet caregiving needs. Findings highlight the potential value of expanding family caregiver training to improve HHC outcomes for sepsis survivors and indicate that caregivers of sepsis survivors with poor cognitive function may benefit most.

[5-Year Readmission Status and Risk Factors for Senile Dementia Patients: A Study Based on Chengdu Municipal Medical Insurance Database]

Objective

To study the status quo of the readmission of senile dementia patients in Chengdu, and to analyze the primary diagnosis, the economic burden and the influencing factors of readmission.

Methods

Dementia inpatients aged 60 and above in Chengdu were the subjects of this study. The subjects were diagnosed with dementia between 2013 and 2017. Their heath insurance coverage was either the basic medical insurance for urban employees in Chengdu or the basic medical insurance for urban and rural residents of Chengdu. The rank sum test and the chi-square test were conducted to analyze the differences in readmission rate and the economic burden of hospitalization among subjects with different characteristics. Logistic regression was done to analyze the factors affecting readmission.

Results

The total number of dementia inpatients over the 5-year period was 27881 patients (78820 admissions). The 30-day readmission rate was 25.14% (7011/27881) and the 5-year readmission rate was 45.79% (12767/27881). The primary diagnoses of 12767 readmitted patients mainly included dementia (28.57%), circulatory system diseases (24.26%), and respiratory system diseases (23.71%). The economic burden of hospitalization was higher for readmitted patients than that of patients who were not readmitted ( Z=33.777, P<0.001). The occurrence of readmission was correlated to the following factors, advanced age (compared to that of the 60-65 yr. group, the 70-75 yr. group: odds ratio [ OR]=1.123, 95% confidence interval [ CI]: 1.019-1.237, and the 75-80 yr. group: OR=1.123, 95% CI: 1.108-1.218), participation in the basic medical insurance for urban employees ( OR=1.674, 95% CI: 1.578-1.775), types of dementia (compared to unspecified dementia, Alzheimer's dementia group: OR=1.256, 95% CI: 1.163-1.357, Parkinson's disease dementia group: OR=1.774, 95% CI: 1.658-1.898, and mixed-type dementia group: OR=1.750, 95% CI: 1.457-2.103), disease condition (compared with patients with only dementia, those who have other diseases: OR=0.536，95% CI ：0.493-0.583), length of hospital stay ( OR=1.593, 95% CI: 1.552-1.635), and staying at a lower level hospital (compared to that of tertiary hospitals, secondary hospitals: OR=1.319, 95% CI: 1.248-1.395, primary hospitals: OR=1.744, 95% CI: 1.608-1.891, and other hospitals: OR=1.465, 95% CI: 1.311-1.537).

Conclusion

Senile dementia patients have a high 30-day readmission rate, and the readmission entails heavy economic burdens on the patients. For the populations covered by medical insurance, the following features are correlated to the occurrence of readmission: advanced age, coverage by the basic medical insurance for urban employees, Alzheimer's dementia, Parkinson's disease dementia, mixed-type dementia, dementia patients without other comorbidities, extended length of stay, and hospitalization at a lower level hospital. However, further research is needed for better understanding of the specific mechanisms so that readmission of senile dementia patients can be reduced and the economic burden of the disease can be minimized.

Potentially avoidable causes of hospitalisation in people with dementia: contemporaneous associations by stage of dementia in a South London clinical cohort

OBJECTIVES

To estimate the frequency of all-cause and ambulatory care sensitive condition (ACSCs)-related hospitalisations among individuals with dementia. In addition, to investigate differences by stage of dementia based on recorded cognitive function.

SETTING

Data from a large London dementia care clinical case register, linked to a national hospitalisation database.

PARTICIPANTS

Individuals aged ≥65 years with a confirmed dementia diagnosis with recorded cognitive function.

OUTCOME MEASURES

Acute general hospital admissions were evaluated within 6 months of a randomly selected cognitive function score in patients with a clinical diagnosis of dementia. To evaluate associations between ACSC-related hospital admissions (overall and individual ACSCs) and stage of dementia, an ordinal regression was performed, modelling stage of dementia as the dependant variable (to facilitate efficient model selection, with no implication concerning the direction of causality).

RESULTS

Of the 5294 people with dementia, 2993 (56.5%) had at least one hospitalisation during a 12-month period of evaluation, and 1192 (22.5%) had an ACSC-related admission. Proportions with an all-cause or ACSC-related hospitalisation were greater in the groups with more advanced dementia (all-cause 53.9%, 57.1% and 60.9%, p 0.002; ACSC-related 19.5%, 24.0% and 25.3%, p<0.0001 in the mild, moderate and severe groups, respectively). An ACSC-related admission was associated with 1.3-fold (95% CI 1.1 to 1.5) increased odds of more severe dementia after adjusting for demographic factors. Concerning admissions for individual ACSCs, the most common ACSC was urinary tract infection /pyelonephritis (9.8% of hospitalised patients) followed by pneumonia (7.1%); in an adjusted model, these were each associated with 1.4-fold increased odds of more severe dementia (95% CI 1.2 to 1.7 and 1.1 to 1.7, respectively).

CONCLUSIONS

Potentially avoidable hospitalisations were common in people with dementia, particularly in those with greater cognitive impairment. Our results call for greater attention to the extent of cognitive status impairment, and not just dementia diagnosis, when evaluating measures to reduce the risk of potentially avoidable hospitalisations.

Data Science Trends Relevant to Nursing Practice: A Rapid Review of the 2020 Literature

BACKGROUND

The term "data science" encompasses several methods, many of which are considered cutting edge and are being used to influence care processes across the world. Nursing is an applied science and a key discipline in health care systems in both clinical and administrative areas, making the profession increasingly influenced by the latest advances in data science. The greater informatics community should be aware of current trends regarding the intersection of nursing and data science, as developments in nursing practice have cross-professional implications.

OBJECTIVES

This study aimed to summarize the latest (calendar year 2020) research and applications of nursing-relevant patient outcomes and clinical processes in the data science literature.

METHODS

We conducted a rapid review of the literature to identify relevant research published during the year 2020. We explored the following 16 topics: (1) artificial intelligence/machine learning credibility and acceptance, (2) burnout, (3) complex care (outpatient), (4) emergency department visits, (5) falls, (6) health care-acquired infections, (7) health care utilization and costs, (8) hospitalization, (9) in-hospital mortality, (10) length of stay, (11) pain, (12) patient safety, (13) pressure injuries, (14) readmissions, (15) staffing, and (16) unit culture.

RESULTS

Of 16,589 articles, 244 were included in the review. All topics were represented by literature published in 2020, ranging from 1 article to 59 articles. Numerous contemporary data science methods were represented in the literature including the use of machine learning, neural networks, and natural language processing.

CONCLUSION

This review provides an overview of the data science trends that were relevant to nursing practice in 2020. Examinations of such literature are important to monitor the status of data science's influence in nursing practice.

Association of Dementia Severity and Caregiver Support With Early Discharge From Home Health

INTRODUCTION

The objective of this study was to examine the relationship between dementia severity and early discharge from home health.

METHODS

This was a retrospective study of 100% national Medicare home health da ta files (2016-2017). Multilevel logistic regression was used to study the relationship of dementia severity, caregiver support, and medication assistance with early discharge from home health.

RESULTS

The final cohort consisted of 91 302 Medicare beneficiaries with an ADRD diagnosis. A pattern of early discharge rates across dementia severity levels was not demonstrated. The relative risk for early discharge was lower for individuals who needed assistance with medication and for those with unmet caregiver needs.

DISCUSSION

The findings of this study do not support the hypothesis that dementia severity contributes to early discharge from home health. Further research is needed to fully understand key factors contributing to early discharge from home health.

Cognitive impairment among medicare home health patients: comparing available measures

There is growing interest in understanding home health utilization and outcomes for those with cognitive impairment (CI). Yet, approaches to measuring CI during home health vary widely across studies, with little known regarding potential implications for findings. Among a nationally representative sample of community-living Medicare beneficiaries receiving home health (2011-2016), we compare estimated CI prevalence using four different measures and evaluate measure-specific strengths and limitations. CI prevalence estimates ranged from 18.4% of the sample with probable dementia from national survey data; to 27.8% with diagnosed dementia, from Medicare claims; to 26.7% with memory deficit and/or impaired decision-making and 43.9% with reduced cognitive function, from OASIS. Researchers must be deliberate in their choice of CI measure and transparent regarding its benefits and limitations. Regardless of the measure used, a sizable percentage of home health patients have CI, supporting the importance of ongoing research in this area.

Characteristics associated with hospitalization within 30 days of geriatric intermediate care facility admission

AIM

To identify facility-level characteristics associated with hospitalization within 30 days after admission to a geriatric intermediate care facility (GICF) (30-day hospitalization) in Japan.

METHODS

This retrospective cohort study used nationwide long-term care insurance claims data and a national survey of long-term geriatric care facilities. The study population was residents admitted to GICFs between October 2016 and February 2018. The outcome variable was 30-day hospitalization. The independent variables were facility-level characteristics such as level of healthcare professionals.

RESULTS

The final sample for analysis comprised 282 991 residents of mean age ± SD, 85.8 ± 7.2 years, of whom 12 814 (4.5%) experienced 30-day hospitalization. In a multivariable logistic generalized estimating equation model adjusted for facility- and resident-level characteristics, and clustering GICFs, the odds of 30-day hospitalization were 0.906 times lower (95% confidence interval [CI] 0.857-0.958) among residents in a GICF with dental hygienist than in those in a facility without. Furthermore, the risk of 30-day hospitalization was lower among residents who had been admitted to a GICF with higher staffing levels of pharmacists (adjusted odds ratio [aOR] 0.941, 95% CI 0.899-0.985), registered nurses (aOR 0.931, 95% CI 0.880-0.986), care workers (aOR 0.920, 95% CI 0.879-0.964) and speech-language pathologists (aOR 0.926, 95% CI 0.874-0.982) than in those who had been admitted to a GICF with fewer of these healthcare professionals.

CONCLUSIONS

Transitional care including dental hygienist or higher staffing levels of pharmacists, registered nurses, care workers and speech-language pathologists may be a more effective way to prevent 30-day hospitalization. Geriatr Gerontol Int 2021; 21: 1010-1017.

Healthcare Utilization in Different Stages among Patients with Dementia: A Nationwide Population-Based Study

To evaluate the trend of healthcare utilization among patients with dementia (PwD) in different post-diagnosis periods, Taiwan's nationwide population database was used in this study. PwD were identified on the basis of dementia diagnoses during 2002-2011. We further subdivided the cases into 10 groups from the index year to the 10th year after diagnosis. The frequency of emergency department visits and hospitalizations, the length of stay, outpatient and department visits, and the number of medications used were retrieved. The Joinpoint regression approach was used to estimate the annual percent change (APC) of healthcare utilization. The overall trend of healthcare utilization increased with the progression of dementia, with a significant APC during the first to second year after diagnosis (p < 0.01), except that the frequency of outpatient visits showed a decreasing trend with a significant APC from the first to fifth year. All sex- and age-stratified analyses revealed that male gender and old age contributed to greater use of healthcare services but did not change the overall trend. This study provides a better understanding of medical resource utilization across the full spectrum of dementia, which can allow policymakers, physicians, and caregivers to devise better care plans for PwD.

Association of cognitive impairment severity with potentially avoidable readmissions: A retrospective cohort study of 8897 older patients

INTRODUCTION

Understanding the association between cognitive impairment severity and potentially avoidable readmissions (PARs) in older patients may facilitate the identification of at-risk individuals who would benefit from readmission prevention measures.

METHODS

This retrospective cohort study was conducted using claims data linked with routinely collected cognitive impairment assessment results from a general acute care hospital in Tokyo, Japan. Patients were 65 years or age or older who were discharged from the subject hospital to home or a facility between July 2016 and September 2018.

RESULTS

A multivariable logistic regression analysis adjusted for covariates showed that the odds of PARs within 90 days to the subject hospital for patients with moderate and severe cognitive impairment were 1.418 times (95% confidence interval: 1.005-2.002) and 2.212 times (95% confidence interval: 1.206-4.058) higher, respectively, that for patients with normal cognition.

DISCUSSION

Older inpatients with later-stage cognitive impairment may represent a suitable target population for transitional care programs aimed at reducing readmissions.

Unmet family caregiver training needs associated with acute care utilization during home health care

BACKGROUND/OBJECTIVES

Medicare-certified home health agencies are required to offer family caregiver training, but little is known regarding the potential impact of this training on outcomes during home health care. We estimate the proportion of family caregivers assisting Medicare home health patients who have unmet training needs and examine whether these unmet training needs are associated with older adults' risk of acute care utilization during home health care.

DESIGN

Observational, nationally representative cohort study.

SETTING

Linked National Health and Aging Trends Study, Outcome and Assessment Information Set (OASIS), Medicare Provider of Services file, and Medicare claims data from 2011 to 2016.

PARTICIPANTS

Thousand two hundred seventeen (weighted n = 5,870,905) community-living Medicare beneficiaries who received home health care between 2011 and 2016.

MEASUREMENTS

Family caregivers' unmet training needs measured from OASIS and Medicare claims; home health patients' acute care utilization (including emergency department use and hospitalization) measured from OASIS.

RESULTS

Rates of unmet need for training varied by activity, from 8.2% of family caregivers assisting with household chores to 16.0% assisting with self-care tasks. After controlling for older adult and home health provider characteristics, older adults whose family caregivers had an unmet need for training with any caregiving activity were twice as likely to incur acute care utilization during their home health episode (adjusted odds ratio [aOR]: 2.01, 95% confidence interval [CI]: 1.20-3.38). This relationship held across specific caregiving activities including household chores (aOR: 1.98; 95% CI: 1.13-3.46), medication management (aOR: 2.50; 95% CI: 1.46-4.26), patient supervision (aOR: 2.92; 95% CI: 1.36-6.24), and self-care tasks (aOR: 3.11; 95% CI: 1.62-6.00).

CONCLUSIONS AND RELEVANCE

Unmet training needs among family caregivers are associated with greater likelihood of acute care utilization among Medicare beneficiaries receiving home health care. Identifying and addressing family caregivers' training needs may reduce older adults' risk of acute care utilization during home health care.
