Incomplete Home Health Care Referral After Hospitalization Among Medicare Beneficiaries

The association of neighborhood-level deprivation with glioblastoma outcomes: a single center cohort study

Glioblastoma is the most common primary brain malignancy. Though literature has suggested the association of glioblastoma outcomes and socioeconomic status, there is limited evidence regarding the association of neighborhood-level socioeconomic deprivation on glioblastoma outcomes. The aim of this study was to assess the impact of neighborhood-level socioeconomic deprivation on glioblastoma survival. We retrospectively reviewed all adult glioblastoma patients seen at a single institution from 2008 to 2023. Neighborhood deprivation was assessed via Area Deprivation Index (ADI), with higher ADI indicating greater neighborhood socioeconomic disadvantage. Log-rank tests and multivariate cox regression was used to assess the effect of ADI and other socioeconomic variables while controlling for a priori selected clinical variables with known relevance to survival. In total, 1464 patients met inclusion criteria. The average age at diagnosis was 60 ± 14 years with a median overall survival of 13.8 months (IQR 13-14.8). The median ADI of the cohort was 66(IQR 46-84). Patients with high neighborhood disadvantage had worse overall survival compared to patients with those without (11.7 vs. 14.8 months, p =.001). In the multivariable model, patients with high neighborhood disadvantage had worse overall survival (HR 1.25, 95%CI 1.09-1.43). To account for changes in WHO guidelines, we implemented the model on patients diagnosed between 2017 and 2023 and findings were consistent (HR 1.26,95%CI 1.01-1.56). We report the first study demonstrating glioblastoma patients with higher neighborhood deprivation have worse survival after controlling for other socioeconomic and biomolecular markers. Neighborhood socioeconomic status may be a prognostic marker for glioblastoma survival.

The Association of Area Deprivation Index and Spine Surgery Outcomes: A Systematic and Narrative Review

BACKGROUND AND OBJECTIVES

With an aging population, the prevalence of spine pathology including degenerative spine disease continues to increase. These pathologies present a significant disease burden, often requiring long-term and expensive care. Recent literature has linked several socioeconomic determinants of health with outcomes after spine surgery. We sought to conduct a systematic review to determine the relationship between Area Deprivation Index (ADI), a measure of neighborhood-level socioeconomic status, and objective and patient-reported outcome (PRO) measures after spine surgery and to propose potential interventions.

METHODS

An Embase and Medline search was conducted from inception to April 1st, 2024, for relevant articles assessing ADI and spine surgery outcomes. The inclusion criteria were all North American observational studies available in English that reported on the association of ADI and adult cervical, lumbar, neoplastic, or deformity spine surgery outcomes.

RESULTS

Ten articles met the inclusion criteria resulting in a combined 56 925 patients who had undergone elective surgery for cervical, lumbar, spine metastases, and adult spine deformity pathologies. Two studies reported ADI to be associated with increased costs of care and postoperative lengths of stay after cervical spine surgery. Five studies found the association between high ADI with increased rates of respiratory failure, 90-day emergency room visits, longer lengths of stay, 90-day reoperation rates, and poor PROs after lumbar spine surgery. One study found an association with high ADI and increased 30-day and 90-day readmissions across all spine surgeries, and 1 study found no association between ADI and overall survival after surgery for spinal metastases.

CONCLUSION

Across available literature, high ADI seems to be associated with higher rates of postoperative readmissions and worse PROs. Further studies are needed to better understand the mechanisms underlying the effects of ADI on spine surgery outcomes and identify possible interventions to optimize outcomes.

The Association of Neighborhood-Level Deprivation with Glioblastoma Outcomes: A Single Center Cohort Study

Purpose

Glioblastoma is the most common primary brain malignancy. Though literature has suggested the association of glioblastoma outcomes and socioeconomic status, there is limited evidence regarding the association of neighborhood-level socioeconomic deprivation on glioblastoma outcomes. The aim of this study was to assess the impact of neighborhood-level socioeconomic deprivation on glioblastoma survival.

Methods

We retrospectively reviewed all adult glioblastoma patients seen at a single institution from 2008 to 2023. Neighborhood deprivation was assessed via Area Deprivation Index (ADI), with higher ADI indicating greater neighborhood socioeconomic deprivation. Log-rank tests and multivariate cox regression was used to assess the effect of ADI and other socioeconomic variables while controlling for a priori selected clinical variables with known relevance to survival.

Results

In total, 1464 patients met inclusion criteria. The average age at diagnosis was 60 ± 14 years with a median overall survival of 13.8 months (IQR 13-14.8). The median ADI of the cohort was 66(IQR 46-84). Patients with high ADI had worse overall survival compared to patients with low ADI (11.7 vs 14.8 months, p=.001). In the multivariable model, patients with high ADI had worse overall survival (HR 1.25, 95%CI 1.09-1.43). To account for changes in WHO guidelines, we implemented the model on patients diagnosed between 2017-2023 and findings were consistent (HR 1.26,95%CI 1.01-1.56).

Conclusion

We report the first study demonstrating glioblastoma patients with higher neighborhood deprivation have worse survival after controlling for other socioeconomic and biomolecular markers. Neighborhood socioeconomic status may be a prognostic marker for glioblastoma survival.

Home Health Quality among Hospitalized Older Adults with Alzheimer's Disease and Related Dementia: Association with Race/Ethnicity and Dual Eligibility before and during the COVID Pandemic

OBJECTIVES

During the COVID-19 pandemic, home health agencies (HHAs) discharges following acute hospitalizations increased. This study examined whether racial and ethnic minoritized and socioeconomically disadvantaged patients (ie, Medicare-Medicaid dual-eligible) were differentially discharged to below-average quality HHAs before and during the COVID-19 pandemic. We focused on post-acute patients with Alzheimer's disease and related dementias (ADRD), who are generally frail and have high care needs.

DESIGN

Cohort study.

SETTING AND PARTICIPANTS

We linked 2019 to 2021 Medicare data with Area Deprivation Index (ADI), Home Health Compare, and COVID-19 infection data. We included Medicare beneficiaries with ADRD who were hospitalized for non-COVID-19 conditions and discharged to HHAs between January 2019 and November 2021. The final analytical sample included 426,766 qualified hospitalization events.

METHODS

The outcome variable was whether a patient received care from a below-average quality HHA, defined by an average Quality of Patient Care Star Rating lower than 3.0. Key independent variables included individual race, ethnicity, and Medicare-Medicaid dual status. Linear probability models with county fixed effects were estimated, sequentially adjusting for the individual- and community-level covariates. Sensitivity analysis using various definitions of below-average quality HHAs was conducted.

RESULTS

Before the pandemic, Black and Hispanic individuals had significantly higher probabilities of discharge to below-average quality HHAs compared with white individuals (3.4 and 3.9 percentage points, respectively). Dual-eligible individuals were also 2.5 percentage points more likely to be discharged to below-average quality HHAs. During the pandemic, disparities in being discharged to below-average quality HHAs persisted among racial and ethnic minoritized patients and increased among duals. Findings were consistent with and without adjusting for individual covariates and across different definitions of below-average quality HHA.

CONCLUSIONS AND IMPLICATIONS

Persistent disparities were observed in being discharged to below-average quality HHAs by race, ethnicity, and dual status. Further research is needed to identify factors contributing to these ongoing inequalities.

Post-acute care transitions during COVID-19: Racial, ethnic, and socioeconomic differences in older adults with Alzheimer's disease and related dementia

BACKGROUND

Differences in the post-acute care (PAC) destinations among racial, ethnic, and socioeconomic groups have been documented before the COVID-19 pandemic. Yet, the pandemic's impact on these differences remains unknown. We examined the impact of the COVID-19 pandemic on PAC destinations and its variation by individual race, ethnicity, and socioeconomic status among community-dwelling older adults with Alzheimer's disease and related dementia (ADRD).

METHODS

We linked 2019-2021 national data (Medicare claims, Minimum Data Set, Master Beneficiary Summary File) and several publicly available datasets, including Provider of Services File, Area Deprivation Index, Area Health Resource File, and COVID-19 infection data. PAC discharge destinations included skilled nursing facilities (SNFs), home health agencies (HHA), and homes without services. Key variables of interest included individual race, ethnicity, and Medicare-Medicaid dual status. The analytic cohort included 830,656 community-dwelling Medicare fee-for-service beneficiaries with ADRD who were hospitalized between 2019 and 2021. Regression models with hospital random effects and state-fixed effects were estimated, stratified by the time periods, and adjusted for the individual, hospital, and county-level covariates.

RESULTS

SNF discharges decreased while home and HHA discharges increased during the pandemic. The trend was more prominent among racial and ethnic minoritized groups and even more so among dual-eligible beneficiaries. For instance, the reduction in the probabilities of SNF admissions between the pre-pandemic period and the 2nd year of COVID was 4.6 (White non-duals), 18.5 (White duals), 8.7 (Black non-duals), and 20.1 (Black duals) percentage-point, respectively. We also found that non-duals were more likely to replace SNF with HHA services, while duals were more likely to be discharged home without HHA.

CONCLUSIONS

The COVID-19 pandemic significantly impacted PAC destinations for individuals with ADRD, especially among socioeconomically disadvantaged and racial and ethnic minoritized populations. Future research is needed to understand if and how these transitions may have affected health outcomes.

Differences in Home Health Services and Outcomes Between Traditional Medicare and Medicare Advantage

Importance

Private Medicare Advantage (MA) plans recently surpassed traditional Medicare (TM) in enrollment. However, MA plans are facing scrutiny for burdensome prior authorization and potential rationing of care, including home health. MA beneficiaries are less likely to receive home health, but recent evidence on differences in service intensity and outcomes among home health patients is lacking.

Objective

To examine differences in home health service intensity and patient outcomes between MA and TM.

Design, Setting, and Participants

This cross-sectional study was conducted from January 2019 to December 2022 in 102 home health locations in 19 states and included 178 195 TM and 107 102 MA patients 65 years or older with 2 or fewer 60-day home health episodes. It included a secondary analysis of standardized assessment and visit data. Inverse probability of treatment weighting regression compared service intensity and patient outcomes between MA and TM episodes, accounting for differences in demographic characteristics, medical complexity, functional and cognitive impairments, social environment, caregiver support, and local community factors. Models included office location, year, and reimbursement policy fixed effects. Data were analyzed between September 2023 and July 2024.

Exposure

TM vs MA plan.

Main Outcomes and Measures

Home health length of stay and number of visits from nursing, physical, occupational, and speech therapy, social work, and home health aides. Patient outcomes included improvement in self-care and mobility function, discharge to the community, and transfer to an inpatient facility during home health.

Results

Of 285 297 total patients, 180 283 (63.2%) were female; 586 (0.2%) were American Indian/Alaska Native, 8957 (3.1%) Asian, 28 694 (10.1%) Black, 7406 (2.6%) Hispanic, 1959 (0.7%) Native Hawaiian/Pacific Islander, 237 017 (83.1%) non-Hispanic White, and 678 (0.2%) multiracial individuals. MA patients had shorter home health length of stay by 1.62 days (95% CI, -1.82 to 1.42) and received fewer visits from all disciplines except social work. There were no differences in inpatient transfers. MA patients had 3% and 4% lower adjusted odds of improving in mobility and self-care, respectively (mobility odds ratio [OR], 0.97; 95% CI, 0.94-0.99; self-care OR, 0.96; 95% CI, 0.92-0.99). MA patients were 5% more likely to discharge to the community compared with TM (OR, 1.05; 95% CI, 1.01-1.08).

Conclusions and Relevance

The results of this cross-sectional study suggest that MA patients receive shorter and less intensive home health care vs TM patients with similar needs. Differences may be due to the administrative burden and cost-limiting incentives of MA plans. MA patients experienced slightly worse functional outcomes but were more likely to discharge to the community, which may have negative implications for MA patients, including reduced functional independence or increased caregiver burden.

Racial and Ethnic Disparities in Home Health Referral Among Adult Medicare Patients

BACKGROUND

Home health care (HHC) services following hospital discharge provide essential continuity of care to mitigate risks of posthospitalization adverse outcomes and readmissions, yet patients from racial and ethnic minority groups are less likely to receive HHC visits.

OBJECTIVE

To examine how the association of nurse assessments of patients' readiness for discharge with referral to HHC services at the time of hospital discharge differs by race and ethnic minority group.

RESEARCH DESIGN

Secondary data analysis from a multisite study of the implementation of discharge readiness assessments in 31 US hospitals (READI Randomized Clinical Trial: 09/15/2014-03/31/2017), using linear and logistic models adjusted for patient demographic/clinical characteristics and hospital fixed effects.

SUBJECTS

All Medicare patients in the study's intervention arm (n=14,684).

MEASURES

Patient's race/ethnicity and discharge disposition code for referral to HHC (vs. home) from electronic health records. Patient's Readiness for Hospital Discharge Scale (RHDS) score (0-10 scale) assessed by the discharging nurse on the day of discharge.

RESULTS

Adjusted RHDS scores were similar for non-Hispanic White (8.21; 95% CI: 8.18-8.24), non-Hispanic Black (8.20; 95% CI: 8.12-8.28), Hispanic (7.92; 95% CI: 7.81-8.02), and other race/ethnicity patients (8.09; 95% CI: 8.01-8.17). Non-Hispanic Black patients with low RHDS scores (6 or less) were less likely than non-Hispanic White patients to be discharged with an HHC referral (Black: 26.8%, 95% CI: 23.3-30.3; White: 32.6%, 95% CI: 31.1-34.1).

CONCLUSIONS

Despite similar RHDS scores, Black patients were less likely to be discharged with HHC. A better understanding of root causes is needed to address systemic structural injustice in health care settings.

Impact of an Area Agency on Aging pharmacist-led Community Care Transition Initiative

BACKGROUND

Rural older adults are at risk of readmissions and medication-related problems after hospital discharge.

OBJECTIVES

This study aimed to compare 30-day hospital readmissions between participants and nonparticipants and describe medication therapy problems (MTPs) and barriers to care, self-management, and social needs among participants.

PRACTICE DESCRIPTION

The Michigan Region VII Area Agency on Aging (AAA) Community Care Transition Initiative (CCTI) for rural older adults after hospitalization.

PRACTICE INNOVATION

Eligible AAA CCTI participants were identified by an AAA community health worker (CHW) trained as a pharmacy technician. Eligibility criteria were Medicare insurance; diagnoses at risk of readmission; length of stay, acuity of admission, comorbidities, and emergency department visits score more than 4; and discharge to home from January 2018 to December 2019. The AAA CCTI included a CHW home visit, telehealth pharmacist comprehensive medication review (CMR), and follow-up for up to 1 year.

EVALUATION METHODS

A retrospective cohort study examined the primary outcomes of 30-day hospital readmissions and MTPs, categorized by the Pharmacy Quality Alliance MTP Framework. Primary care provider (PCP) visit completion, barriers to self-management, health, and social needs were collected. Descriptive statistics, Mann-Whitney U, and chi-square analyses were used.

RESULTS

Of 825 eligible discharges, 477 (57.8%) enrolled in the AAA CCTI; differences in 30-day readmissions between participants and nonparticipants were not statistically significant (11.5% vs. 16.1%, P = 0.07). More than one-third of participants (34.6%) completed their PCP visit within 7 days. MTPs were identified in 76.1% of the pharmacist visits (mean MTP 2.1 [SD 1.4]). Adherence (38.2%) and safety-related (32.0%) MTPs were common. Physical health and financial issues were barriers to self-management.

CONCLUSION

AAA CCTI participants did not have lower hospital readmission rates. The AAA CCTI identified and addressed barriers to self-management and MTPs in participants after the care transition home. Community-based, patient-centered strategies to improve medication use and meet rural adults' health and social needs after care transitions are warranted.

Mobile Integrated Health Interventions for Older Adults: A Systematic Review

Background and Objectives

Mobile integrated health (MIH) interventions have not been well described in older adult populations. The objective of this systematic review was to evaluate the characteristics and effectiveness of MIH programs on health-related outcomes among older adults.

Research Design and Methods

We searched Ovid MEDLINE, Ovid EMBASE, CINAHL, AgeLine, Social Work Abstracts, and The Cochrane Library through June 2021 for randomized controlled trials or cohort studies evaluating MIH among adults aged 65 and older in the general community. Studies were screened for eligibility against predefined inclusion/exclusion criteria. Using at least 2 independent reviewers, quality was appraised using the Downs and Black checklist and study characteristics and findings were synthesized and evaluated for potential bias.

Results

Screening of 2,160 records identified 15 studies. The mean age of participants was 67 years. The MIH interventions varied in their focus, community paramedic training, types of assessments and interventions delivered, physician oversight, use of telemedicine, and post-visit follow-up. Studies reported significant reductions in emergency call volume (5 studies) and immediate emergency department (ED) transports (3 studies). The 3 studies examining subsequent ED visits and 4 studies examining readmission rates reported mixed results. Studies reported low adverse event rates (5 studies), high patient and provider satisfaction (5 studies), and costs equivalent to or less than usual paramedic care (3 studies).

Discussion and Implications

There is wide variability in MIH provider training, program coordination, and quality-based metrics, creating heterogeneity that make definitive conclusions challenging. Nonetheless, studies suggest MIH reduces emergency call volume and ED transport rates while improving patient experience and reducing overall health care costs.

Analysis of Functional Recovery in Older Adults Discharged to Skilled Nursing Facilities and Then Home

IMPORTANCE

Although many older adults are discharged to skilled nursing facilities (SNFs) after hospitalization, rates of patients recovery afterward are unknown.

OBJECTIVE

To examine postacute functional recovery among older adults.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study was conducted among older adults treated in SNFs, then at home with home health care (HHC). Participants were a 5% random sample of Medicare fee-for-service beneficiaries discharged to community HHC after SNF stay from 2014 to 2016 with continuous part A and B enrollment in the prior 6 months. Medicare claims data from 2014 to 2016 were used, including inpatient, SNF, hospice, HHC, outpatient, carrier, and durable medical equipment data and Minimum Data Set (MDS) and Outcome Assessment Information Set (OASIS) for SNF and HHC assessments, respectively. Data were analyzed from July 20, 2020, to June 5, 2022.

EXPOSURES

Frailty was measured with a validated claims-based frailty index (CFI) (range, 0-1; higher scores indicate worse frailty) and categorized into not frail (<0.20), mildly frail (0.20-0.29), and moderately to severely frail (≥0.30).

MAIN OUTCOMES AND MEASURES

The primary outcome was functional recovery, defined by discharge from HHC with stable or improved ability to perform activities of daily living (ADL). Recovery status was examined at 15, 30, 45, 60, 75, and 90 days after discharge to HHC using OASIS. Covariates were obtained from the MDS admission file at SNF admission, including age, race and ethnicity, cognitive status, functional status, and geographic region.

RESULTS

Among 105 232 beneficiaries (mean [SD] age, 79.1 [10.6] years; 68 637 [65.2%] women; 8951 Black [8.5%], 3109 Hispanic [3.0%], and 88 583 White [84.2%] individuals), 65 796 individuals (62.5%) were discharged from HHC services with improved function over 90 days of follow-up. Among 39 436 beneficiaries not recovered, 19 612 individuals (49.7%) had mild frailty and 15 818 individuals (40.1%) had moderate to severe frailty. While 10 492 of 17 576 beneficiaries who were not frail recovered by 45 days (59.7%), 10 755 of 32 212 individuals with moderate to severe frailty had recovered (33.4%). Overall, frailty was negatively associated with functional recovery after adjustment for demographic characteristics, geographic census regions, and health-related variables, with a hazard ratio for moderate to severe frailty of 0.62 (95% CI, 0.60-0.63) compared with nonfrailty.

CONCLUSIONS AND RELEVANCE

This study found that recovery after posthospitalization SNF stay was particularly prolonged for individuals with frailty. Functional dependence in activities of daily living remained common among individuals with frailty long after discharge home.
