Post-acute care transitions and outcomes among Medicare beneficiaries with dementia: Associations with race/ethnicity and dual status.

ABSTRACT:

Objective

To evaluate how post-acute care (PAC) transitions affect minority older adults with Alzheimer's disease or related dementia (ADRD), and the extent to which dual Medicare-Medicaid eligibility may attenuate or exacerbate disparities in PAC outcomes. We examined: (1) PAC referrals by race/ethnicity and dual status; (2) individual, hospital, and market-level factors associated with PAC; (3) the association between PAC and outcomes.

Data sources/study setting

We used the following secondary data: Master Beneficiary Summary File (MBSF), Medicare Provider Analysis and Review (MedPAR), Minimum Data Set (MDS), Area Health Resource File (AHRF), hospital Provider of Services (POS) file, and the area deprivation index (ADI).

Study design

This observational study consisted of 619,262 community-residing Medicare fee-for-service (FFS) beneficiaries with ADRD who had a hospital stay in 2017.

Data collection/extraction methods

PAC discharge was to skilled nursing facilities (SNF), home health care (HHC) agencies or home without services. Outcomes were 30-day readmission and death. Multinomial logistic regressions with hospital random effects (RE), stratified by dual eligibility, were fit.

Principal findings

Dual-related differences were significantly larger than race/ethnicity differences in PAC transitions. For example, the difference in the probability of SNF transitions between White and Black patients was 3.2% and 6.8%-points for non-duals and duals, respectively. The difference between non-dual/dual White patients was 21.6% points, and among Black patients 18.0%-points. The adjusted risk of 30-day readmission was 5.6 percentage point higher among non-duals discharged to SNF, compared to home, but such risk among duals was not statistically significantly different. The adjusted probabilities of 30-day mortality were larger for duals and non-duals who transitioned to SNF, compared to those discharged home.

Conclusions

PAC referrals and the resulting outcomes for Medicare beneficiaries with ADRD are associated with multi-level variables that need to be incorporated in discharge decision making.

Project description:IntroductionWe aimed to determine if racial/ethnic disparities exist in survivorship care patient experiences among older breast cancer survivors.Materials and methodsNineteen thousand seventeen female breast cancer survivors aged ≥65 at post-diagnosis survey contributed data via the National Cancer Institute Surveillance, Epidemiology, and End Results (SEER) and Centers for Medicare and Medicaid Services Consumer Assessment of Healthcare Providers & Systems (CAHPS) data linkage (2000-2019). Multivariable linear regression models were used to estimate adjusted beta (β) coefficients and standard error (SE) estimates for associations between race/ethnicity and survivorship care patient experiences.ResultsMost women were non-Hispanic (NH)-White (78.1%; NH-Black [8.1%], NH-Asian [6.5%], Hispanic [6.2%]). On average, women reported 76.3 years (standard deviation [SD] = 7.14) at CAHPS survey and 6.10 years since primary diagnosis (SD = 3.51). Compared with NH-White survivors, NH-Black survivors reported lower mean scores for Getting Care Quickly (β = -5.17, SE = 0.69, p ≤0.001), Getting Needed Care (β = -1.72, SE = 0.63, p = 0.006), and Overall Care Ratings (β = -2.72, SE = 0.48, p ≤0.001), mirroring the results for NH-Asian survivors (Getting Care Quickly [β = -7.06, SE = 0.77, p ≤0.001], Getting Needed Care [β = -4.43, SE = 0.70, p ≤0.001], Physician Communication [β = -1.15, SE = 0.54, p = 0.03], Overall Care Rating [β = -2.32, SE = 0.53, p ≤0.001]). Findings among Hispanic survivors varied, where mean scores were lower for Getting Care Quickly (β = -2.83, SE = 0.79, p ≤0.001), Getting Needed Care (β = -2.43, SE = 0.70, p = 0.001), and Getting Needed Prescription Drug(s) (β = -1.47, SE = 0.64, p = 0.02), but were higher for Health Plan Rating (β = 2.66, SE = 0.55, p ≤0.001). Education, Medicare plan, and multimorbidity significantly modified various associations among NH-Black survivors, and education was a significant modifier among NH-Asian and Hispanic survivors.DiscussionWe observed racial/ethnic disparities in the associations with survivorship care patient experience among NH-Black, Hispanic, and NH-Asian breast cancer survivors. Future research should examine the impact of education, Medicare plans, and multimorbidity on these associations.

Project description:ImportanceRural patients with colon cancer experience worse outcomes than urban patients, but the extent to which disparities are explained by social determinants is not known.ObjectivesTo evaluate the association of rurality with surgical treatment and outcomes of colon cancer and to investigate the intersection of rurality with race and ethnicity and socioeconomic status.Design, settings, and participantsThis cohort study included fee-for-service Medicare beneficiaries 65 years or older diagnosed with incident, nonmetastatic colon cancer between April 1, 2016, and September 30, 2018, with follow-up until December 31, 2018. Data were analyzed from August 3, 2020, to April 30, 2021.ExposuresRurality of patient's residence, categorized as metropolitan, micropolitan, or small town or rural, using Rural-Urban Commuting Area codes.Main outcomes and measuresReceipt of surgery, emergent surgery, or minimally invasive surgery (MIS); 90-day surgical complications; and 90-day mortality.ResultsAmong 57 710 Medicare beneficiaries with incident, nonmetastatic colon cancer, 46.6% were men, 53.4% were women, and the mean (SD) age was 76.6 (7.2) years. In terms of race and ethnicity, 3.7% were Hispanic, 6.4% were non-Hispanic Black (hereinafter Black), 86.1% were non-Hispanic White (hereinafter White), and 3.8% were American Indian or Alaska Native, Asian or Pacific Islander, or unknown race or ethnicity. Patients residing in nonmetropolitan areas were more likely to undergo surgical resection than those residing in metropolitan areas (69.2% vs 63.9%; P < .001). Black race was independently associated with lower hazard of surgical resection (hazard ratio, 0.92 [95% CI, 0.88-0.95]). Race and ethnicity and measures of socioeconomic status did not modify the association of rurality with surgery. Beneficiaries from small town and rural areas had higher odds of undergoing emergent surgery (adjusted odds ratio [OR], 1.32 [95% CI, 1.20-1.44]) but lower odds of undergoing MIS (adjusted OR, 0.75 [95% CI, 0.70-0.80]), with similar findings for patients residing in micropolitan areas. Members of racial and ethnic minority groups who resided in small town and rural settings experienced higher odds of postoperative surgical complications (P = .001 for interaction) and mortality (P = .001 for interaction). Notably, White patients who resided in small town and rural areas experienced lower odds of postoperative mortality than their White metropolitan counterparts (adjusted OR, 0.81 [95% CI, 0.71-0.92]), but Black patients who resided in small town and rural areas had significantly higher odds of postoperative mortality (adjusted OR, 1.86 [95% CI, 1.16-2.97]) than their Black metropolitan counterparts.Conclusions and relevanceThese findings suggest that Medicare beneficiaries from small town and rural areas were more likely to undergo surgery for nonmetastatic colon cancer than metropolitan beneficiaries but also more likely to undergo emergent surgery and less likely to have MIS. The experiences of rural patients varied by race; rurality was associated with higher postoperative mortality for Black patients but not for other racial and ethnic groups.

Project description:BackgroundDespite the rapid growth of assisted living (AL) and frequent hospitalizations among AL residents, little is known about their patterns of post-acute care transitions and outcomes. This study examined the post-acute care transitions among AL residents and their association with outcomes in the first 30 and 60 days after hospital discharge.MethodsThis study used data from 2018 national Medicare enrollment and claims datasets, the Minimum Data Set (MDS), and Medicare Provider Analysis and Review (MedPAR) of 104,497 unique Medicare beneficiaries residing in ALs in the U.S. Post-acute care referrals, based on hospital discharge status, to skilled nursing facilities (SNF), home with home health care (HHC), home without HHC, and other settings. Outcomes included 30-day and 60-day hospital readmissions, emergency department (ED) visits, long-stay care nursing home placement, and mortality. Multinomial logistic regression analysis and logistic regression analysis were conducted.ResultsThe most common post-acute care referral was to SNF (40%), followed by home without HHC (28%), home with HHC (17%), and others (15%). Compared to discharge home without HHC, discharge to SNF was associated with a lower likelihood of ED visits (Odds Ratio = 0.597, p < 0.01) and hospital readmissions (OR = 0.856, p < 0.001), and higher likelihood of long-stay nursing home placement (OR = 11.224, p < 0.01) and mortality (OR = 2.025, p < 0.01). Discharge home with HHC was associated with a higher likelihood of hospital readmissions (OR = 1.148, p < 0.01) and a lower likelihood of long-stay nursing home placement (OR = 0.737, p < 0.05) than discharge home without HHC. The results were similar within the first 30 days as well as 60 days after hospital discharge.ConclusionsAL residents who are discharged to different post-acute care settings tend to differ in 30-day and 60-day outcomes. At hospital discharge, clinicians and discharge planners should be provided information about the exact type and availability of services at AL to make the most appropriate discharge referrals for AL residents.

Project description:Background/objectivesNo data exist regarding the validity of International Classification of Disease (ICD)-10 dementia diagnoses against a clinician-adjudicated reference standard within Medicare claims data. We examined the accuracy of claims-based diagnoses with respect to expert clinician adjudication using a novel database with individual-level linkages between electronic health record (EHR) and claims.DesignIn this retrospective observational study, two neurologists and two psychiatrists performed a standardized review of patients' medical records from January 2016 to December 2018 and adjudicated dementia status. We measured the accuracy of three claims-based definitions of dementia against the reference standard.SettingMass-General-Brigham Healthcare (MGB), Massachusetts, USA.ParticipantsFrom an eligible population of 40,690 fee-for-service (FFS) Medicare beneficiaries, aged 65 years and older, within the MGB Accountable Care Organization (ACO), we generated a random sample of 1002 patients, stratified by the pretest likelihood of dementia using administrative surrogates.InterventionNone.MeasurementsWe evaluated the accuracy (area under receiver operating curve [AUROC]) and calibration (calibration-in-the-large [CITL] and calibration slope) of three ICD-10 claims-based definitions of dementia against clinician-adjudicated standards. We applied inverse probability weighting to reconstruct the eligible population and reported the mean and 95% confidence interval (95% CI) for all performance characteristics, using 10-fold cross-validation (CV).ResultsBeneficiaries had an average age of 75.3 years and were predominately female (59%) and non-Hispanic whites (93%). The adjudicated prevalence of dementia in the eligible population was 7%. The best-performing definition demonstrated excellent accuracy (CV-AUC 0.94; 95% CI 0.92-0.96) and was well-calibrated to the reference standard of clinician-adjudicated dementia (CV-CITL <0.001, CV-slope 0.97).ConclusionThis study is the first to validate ICD-10 diagnostic codes against a robust and replicable approach to dementia ascertainment, using a real-world clinical reference standard. The best performing definition includes diagnostic codes with strong face validity and outperforms an updated version of a previously validated ICD-9 definition of dementia.

Project description:ImportanceBlack and Hispanic US residents are disproportionately affected by stroke incidence, and patients with dual eligibility for Medicare and Medicaid may be predisposed to more severe strokes. Little is known about differences in stroke severity for individuals with dual eligibility, Black individuals, and Hispanic individuals, but understanding hospital admission stroke severity is the first important step for focusing strategies to reduce disparities in stroke care and outcomes.ObjectiveTo examine whether dual eligibility and race and ethnicity are associated with stroke severity in Medicare beneficiaries admitted to acute hospitals with ischemic stroke.Design, setting, and participantsThis retrospective cross-sectional study was conducted using Medicare claims data for patients with ischemic stroke admitted to acute hospitals in the United States from October 1, 2016, to November 30, 2017. Data were analyzed from July 2021 and January 2022.ExposuresDual enrollment for Medicare and Medicaid; race and ethnicity categorized as White, Black, Hispanic, and other.Main outcomes and measuresClaim-based National Institutes of Health Stroke Scale (NIHSS) categorized into minor (0-7), moderate (8-13), moderate to severe (14-21), and severe (22-42) stroke.ResultsOur sample included 45 459 Medicare fee-for-service patients aged 66 and older (mean [SD] age, 80.2 [8.4]; 25 303 [55.7%] female; 7738 [17.0%] dual eligible; 4107 [9.0%] Black; 1719 [3.8%] Hispanic; 37 715 [83.0%] White). In the fully adjusted models, compared with White patients, Black patients (odds ratio [OR], 1.21; 95% CI, 1.06-1.39) and Hispanic patients (OR, 1.54; 95% CI, 1.29-1.85) were more likely to have a severe stroke. Using White patients without dual eligibility as a reference group, White patients with dual eligibility were more likely to have a severe stroke (OR, 1.75; 95% CI, 1.56-1.95). Similarly, Black patients with dual eligibility (OR, 2.15; 95% CI, 1.78-2.60) and Hispanic patients with dual eligibility (OR, 2.50; 95% CI, 1.98-3.16) were more likely to have a severe stroke.Conclusions and relevanceIn this cross-sectional study, Medicare fee-for-service patients with ischemic stroke admitted to acute hospitals who were Black or Hispanic had a higher likelihood of worse stroke severity. Additionally, dual eligibility status had a compounding association with stroke severity regardless of race and ethnicity. An urgent effort is needed to decrease disparities in access to preventive and poststroke care for dual eligible and minority patients.
