Disability, health, and multiple chronic conditions among people eligible for both Medicare and Medicaid, 2005-2010

Disparities in Treatment for Alcohol Use Disorder Among All of Us Participants

OBJECTIVE

The authors examined racial/ethnic and socioeconomic disparities in receiving treatment for alcohol use disorder (AUD).

METHODS

A retrospective cohort study was conducted that included adults (≥18 years) with AUD from the All of Us Controlled Tier database v7. Outcomes were lifetime receipt of FDA-approved medications (disulfiram, acamprosate, and naltrexone), psychotherapy (individual, family, and group-based session), and combination treatment (medication and psychotherapy). The study examined treatment receipt by race/ethnicity (non-Hispanic White, non-Hispanic Black, Hispanic, other), insurance (private, Medicare, Medicare and Medicaid, Medicaid, Veteran Affairs [VA], none), income (<$10K, $10-<$50K, $50-$100K, >$100K), and area deprivation index (ADI) quintiles. Multivariable logistic and multinomial logistic regressions were used to assess the association between patient characteristics and treatment receipt.

RESULTS

The cohort consisted of 18,692 patients (mean age=57.1 years; 60.7% were male; 47.1% were non-Hispanic White). Almost 70% received no treatment, 11.4% received medication, 24.0% received psychotherapy, and 4.9% received combination treatment. In adjusted analysis, non-Hispanic Black (aOR=0.78, 95% CI=0.69-0.89) and Hispanic (aOR=0.75, 95% CI=0.64-0.88) individuals were less likely to receive medication than non-Hispanic White counterparts. There was no association between race/ethnicity and receipt of psychotherapy or combination treatment. Compared with private insurance, dual eligibility was associated with less use of medication, Medicare and Medicaid with less use of medication and combination treatment, and VA and no insurance with more use of psychotherapy and combination treatment. Higher income and lower ADI were positively associated with all treatment types.

CONCLUSIONS

There are disparities in AUD treatment by race/ethnicity, socioeconomic status, and insurance. Systematic approaches are required to improve equitable access to effective treatment.

Independent and joint contributions of physical disability and chronic pain to incident opioid use disorder and opioid overdose among Medicaid patients

BACKGROUND

Chronic pain has been extensively explored as a risk factor for opioid misuse, resulting in increased focus on opioid prescribing practices for individuals with such conditions. Physical disability sometimes co-occurs with chronic pain but may also represent an independent risk factor for opioid misuse. However, previous research has not disentangled whether disability contributes to risk independent of chronic pain.

METHODS

Here, we estimate the independent and joint adjusted associations between having a physical disability and co-occurring chronic pain condition at time of Medicaid enrollment on subsequent 18-month risk of incident opioid use disorder (OUD) and non-fatal, unintentional opioid overdose among non-elderly, adult Medicaid beneficiaries (2016-2019).

RESULTS

We find robust evidence that having a physical disability approximately doubles the risk of incident OUD or opioid overdose, and physical disability co-occurring with chronic pain increases the risks approximately sixfold as compared to having neither chronic pain nor disability. In absolute numbers, those with neither a physical disability nor chronic pain condition have a 1.8% adjusted risk of incident OUD over 18 months of follow-up, those with physical disability alone have an 2.9% incident risk, those with chronic pain alone have a 3.6% incident risk, and those with co-occurring physical disability and chronic pain have a 11.1% incident risk.

CONCLUSIONS

These findings suggest that those with a physical disability should receive increased attention from the medical and healthcare communities to reduce their risk of opioid misuse and attendant negative outcomes.

Social Determinants of Health and Multimorbidity Among Adults 50 Years and Older in the United States

BACKGROUND

Living with two or more chronic conditions simultaneously-known as multimorbidity-has become increasingly prevalent as the aging population continues to grow. However, the factors that influence the development of multimorbidity are still not fully understood.

OBJECTIVES

The purpose of this study was to investigate the prevalence of multimorbidity among U.S. adults 50 years and older and identify associated factors with multimorbidity.

METHODS

We used data from four cycles from the National Health and Nutrition Examination Survey (2011-2018) to examine the associations between social determinants of health and multimorbidity among American adults aged 50 years and older. A set of variables on socioeconomic status and health behaviors was chosen based on the social determinants of health conceptual framework developed by the World Health Organization. In our study, 4,552 participants were included. All analyses were accounted for a complex survey design and the use of survey weights. Multiple logistic regression analyses were performed to examine the associated factors with multimorbidity.

RESULTS

The average age was 63.1 years, and 52.9% were female. The average number of chronic conditions was 2.27. The prevalence of multimorbidity was 63.8%, with high cholesterol and hypertension being the most prevalent conditions. In the adjusted model, age, gender, household income, citizenship status, health insurance, healthcare access, body mass index, and smoking status were found to be associated with living with multimorbidity.

DISCUSSION

Our results indicate that continued efforts aimed at promoting smoking cessation and maintaining a healthy weight will be beneficial in preventing the onset of chronic conditions. Additional research is warranted to gain a deeper understanding of the interrelationships between gender, race/ethnicity, household income, citizenship status, health insurance, and healthcare access as social determinants of health in the context of multimorbidity. Further research will help us develop targeted interventions and policies to address disparities and improve health outcomes for individuals with multimorbidity.

A comparison of clinical, utilization, and cost outcomes between oral treatments for multiple sclerosis

BACKGROUND

Multiple sclerosis (MS) affects nearly 1 million people in the United States and causes significant disability and economic loss. Among the first available oral MS treatment options, clinical outcome comparisons and associated health care resource utilization are not clearly defined.

OBJECTIVE

To compare MS outcomes, health care resource utilization, and relative costs across treatment with dimethyl fumarate (DMF), fingolimod (FG), or teriflunomide (TERI) among Medicare Advantage Prescription Drug (MAPD) plan and commercially insured beneficiaries.

METHODS

This retrospective cohort study used the Humana Research Database. Eligible study patients had their first MS medication claim for oral DMG, FG, or TERI between January 1, 2013, and December 31, 2018. Patients were followed for a minimum of 12 months (mean follow-up = 3.8 years), until the earliest of the following occurred: health plan disenrollment, the end of the study period, or death. Study cohorts were balanced with inverse probability of treatment weighting. All-cause and MS-related health care resource utilization, time on therapy, and time after therapy were compared using inverse probability of treatment-adjusted multivariate generalized linear models across treatment groups. Relative costs were compared using a generalized linear model with a gamma distribution and log link.

RESULTS

We identified 1,442 patients in 3 medication groups: DMF (n = 843), FG (n = 213), and TERI (n = 386). After weighting, there were no significant differences between the medication groups on demographic and clinical characteristics. Time on therapy (days) was significantly different across medication groups (P < 0.001). Time on therapy was longest for FG compared with the DM and TERI groups (644 vs 462 vs 521). The number discontinuing the index medication was significantly different for FG vs DMF vs TERI (74.7% vs 85.3% vs 80.7%; P < 0.001). FG had the lowest discontinuation rate. The mean (SD) annualized relapse rates (ARRs) were 0.47 (0.80), 0.42 (1.3), and 0.53 (1.3) (P = 0.037) for DMF, FG, and TERI, respectively. The percentage of those experiencing inpatient stays and the number of stays (mean [SD]) were significantly different among the FG group vs DMF vs TERI (29.9% vs 34.1% vs 40.9%; P < 0.001) and (0.57 [2.9] vs 0.74 [1.9] vs 0.91 [3.5]; P = 0.007), respectively. All-cause emergency department visits and the number of visits (mean [SD]) were significantly different for the FG cohort vs DMF vs TERI (46% vs 54.3% vs 61%; P < 0.001) and (1.84 [7.7] vs 2.38 [5.9] vs 2.87 [8.8]; P = 0.002), respectively. FG had the lowest impatient stays and emergency department visits of the 3 groups.

CONCLUSIONS

Patients with MS initiated on FG used fewer health care resources and experienced lower ARR compared with patients on DMF and TERI.

Diabetes Among Racial and Ethnically Diverse Older Adults in the United States with Cognitive Limitations

Diabetes is one of the most common coexisting conditions among adults with cognitive limitations. Complexities of diabetes care present challenges for older adults and their caregivers. Few studies have evaluated disparities in the prevalence of coexisting diabetes among older adults with cognitive limitations by race/ethnicity and nativity. Our objectives were to (1) estimate the odds of coexisting diabetes among US- and foreign-born racial/ethnic groups compared to US-born non-Hispanic White older adults and (2) compare US- and foreign-born older adults within each racial/ethnic group. We linked and analyzed 2000-2017 National Health Interview Survey and 2001-2018 Medical Expenditure Panel Survey data among older adults with cognitive limitations (ages ≥ 65 years, n = 4688). The overall prevalence of coexisting diabetes among older adults with cognitive limitations was 30.3%. Among older adults with cognitive limitations and after adjusted for age, sex, education, and risk factors for diabetes and cognitive limitations, non-Hispanic Black (US-born OR = 1.56, 95%CI = 1.23-1.98; foreign-born OR = 2.69, 95%CI = 1.20-6.05) and Hispanic (US-born OR = 2.13, 95%CI = 1.34-3.40; foreign-born OR = 2.02, 95%CI = 1.49-2.72) older adults had higher odds of coexisting diabetes compared to US-born non-Hispanic Whites. There were no differences in the odds of coexisting diabetes among foreign-born non-Hispanic Black and Hispanic adults compared to US-born counterparts. Findings suggest a large potential burden of coexisting diabetes among this growing populations of US- and foreign-born racially/ethnically diverse older adults with cognitive limitations. Future studies are needed to examine how diabetes self-efficacy, treatment, and monitoring are impacted by cognitive limitations and determine ways to improve care in collaboration with caregivers and healthcare providers.

Racial/Ethnic Differences in Risk Factors Associated With Severe COVID-19 Among Older Adults With ADRD

OBJECTIVE

To examine racial/ethnic differences in risk factors, and their associations with COVID-19-related outcomes among older adults with Alzheimer's disease and related dementias (ADRD).

DESIGN

Observational study.

SETTING AND PARTICIPANTS

National Medicare claims data and the Minimum Data Set 3.0 from April 1, 2020, to December 31, 2020, were linked in this study. We included community-dwelling fee-for-service Medicare beneficiaries with ADRD, diagnosed with COVID-19 between April 1, 2020, and December 1, 2020 (N = 138,533).

METHODS

Two outcome variables were defined: hospitalization within 14 days and death within 30 days of COVID-19 diagnosis. We obtained information on individual sociodemographic characteristics, chronic conditions, and prior health care utilization based on the Medicare claims and the Minimum Dataset. Machine learning methods, including lasso regression and discriminative pattern mining, were used to identify risk factors in racial/ethnic subgroups (ie, White, Black, and Hispanic individuals). The associations between identified risk factors and outcomes were evaluated using logistic regression and compared across racial/ethnic subgroups using the coefficient comparison approach.

RESULTS

We found higher risks of COVID-19-related outcomes among Black and Hispanic individuals. The areas under the curve of the models with identified risk factors were 0.65 to 0.68 for mortality and 0.61 to 0.62 for hospitalization across racial/ethnic subgroups. Although some identified risk factors (eg, age, gender) for COVID-19-related outcomes were common among all racial/ethnic subgroups, other risk factors (eg, hypertension, obesity) varied by racial/ethnic subgroups. Furthermore, the associations between some common risk factors and COVID-19-related outcomes also varied by race/ethnicity. Being male was related to 138.2% (95% CI: 1.996-2.841), 64.7% (95% CI: 1.546-1.755), and 37.1% (95% CI: 1.192-1.578) increased odds of death among Hispanic, White, and Black individuals, respectively. In addition, the racial/ethnic disparity in COVID-19-related outcomes could not be completely explained by the identified risk factors.

CONCLUSIONS AND IMPLICATIONS

Racial/ethnic differences were detected in the likelihood of having COVID-19-related outcomes, specific risk factors, and relationships between specific risk factors and COVID-19-related outcomes. Future research is needed to elucidate the reasons for these differences.

Factors Associated With Blood Pressure Control Among Patients in Community Health Centers

INTRODUCTION

Understanding the multilevel factors associated with controlled blood pressure is important to determine modifiable factors for future interventions, especially among populations living in poverty. This study identified clinically important factors associated with blood pressure control among patients receiving care in community health centers.

METHODS

This study includes 31,089 patients with diagnosed hypertension by 2015 receiving care from 103 community health centers; aged 19-64 years; and with ≥1 yearly visit with ≥1 recorded blood pressure in 2015, 2016, and 2017. Blood pressure control was operationalized as an average of all blood pressure measurements during all the 3 years and categorized as controlled (blood pressure <140/90), partially controlled (mixture of controlled and uncontrolled blood pressure), or never controlled. Multinomial mixed-effects logistic regression models, conducted in 2022, were used to calculate unadjusted ORs and AORs of being in the never- or partially controlled blood pressure groups versus in the always-controlled group.

RESULTS

A total of 50.5% had always controlled, 39.7% had partially controlled, and 9.9% never had controlled blood pressure during the study period. The odds of being partially or never in blood pressure control were higher for patients without continuous insurance (AOR=1.09; 95% CI=1.03, 1.16; AOR=1.18; 95% CI=1.07, 1.30, respectively), with low provider continuity (AOR=1.24; 95% CI=1.15, 1.34; AOR=1.28; 95% CI=1.13, 1.45, respectively), with a recent diagnosis of hypertension (AOR=1.34; 95% CI=1.20, 1.49; AOR=1.19; 95% CI=1.00, 1.42), with inconsistent antihypertensive medications (AOR=1.19; 95% CI=1.11, 1.27; AOR=1.26; 95% CI=1.13, 1.41, respectively), and with fewer blood pressure checks (AOR=2.14; 95% CI=1.97, 2.33; AOR=2.17; 95% CI=1.90, 2.48, respectively) than for their counterparts.

CONCLUSIONS

Efforts targeting continuous and consistent access to care, antihypertensive medications, and regular blood pressure monitoring may improve blood pressure control among populations living in poverty.

Dual-eligible, dual-risk? A brief review on the impact of dual-eligible status on health disparities and peripheral artery disease

Peripheral artery disease (PAD) has been associated with poorer outcomes based on particular social determinants of health, including insurance status. A unique population to study treatment outcomes related to PAD is those with dual-eligible status-those who qualify for both Medicare and Medicaid-comprising more than 12 million people. We performed a systematic review of the literature surrounding dual-eligible patients and impact on PAD, with final inclusion of six articles. Dual eligibility has been associated with higher rates of comorbidities; more severe symptoms at initial presentation for PAD; and poorer treatment outcomes, including mortality. Further studies are needed to specifically look at the association between PAD and dual-eligible status, but what is clear is that patients in this population would benefit from early identification to prevent disease progression and improve equity.

High Blood Pressure Reduction, Health Insurance Status, and Social Deprivation Index in U.S. Community Health Centers

Introduction

Lack of health insurance is a risk factor for uncontrolled hypertension, but it is unknown whether health insurance or neighborhood-level social deprivation is associated with greater reductions in blood pressure over time.

Methods

We estimated the association of health insurance and social deprivation index on blood pressure reduction over time using electronic health record data from 2012 to 2017. We included patients aged 19-64 years with an initial systolic blood pressure ≥150 mmHg or diastolic blood pressure ≥100 mmHg and ≥1 additional visit from 93 community health centers in states that expanded Medicaid in 2014.

Results

We included 66,207 patients: 20.1% uninsured, 64.8% publicly insured, and 15.1% privately insured. Adjusting for patient characteristics and baseline blood pressure, systolic blood pressure/diastolic blood pressure declined over the study period by 21.3/11.2 mmHg, 22.0/11.4 mmHg, and 21.1/10.7 mmHg among uninsured, publicly insured, and privately insured individuals, respectively. There were small but significantly greater reductions in systolic blood pressure among patients with public insurance than among those who were uninsured (difference= -1.3, 95% CI= -1.6, -1.0) but none associated with social deprivation index. There were no differences in diastolic blood pressure reductions over time by insurance status or social deprivation index. Blood pressure control (systolic blood pressure <140 mmHg and diastolic blood pressure <90 mmHg) was significantly greater among publicly or commercially insured individuals than among uninsured individuals (51.7%, 51.5%, 44.6% respectively, both comparisons p<0.001), with no associations between blood pressure control and social deprivation index.

Conclusions

Reductions in blood pressure were large but mostly not associated with insurance type or social deprivation index. Additional research is needed to understand the factors that lead to blood pressure reduction in community health center settings.

Discharge locations after hospitalizations involving opioid use disorder among medicare beneficiaries

BACKGROUND

Hospitalizations involving opioid use disorder (OUD) have been increasing among Medicare beneficiaries of all ages. With rising OUD-related acute care use comes the need to understand where post-acute care is provided and the capacities for OUD treatment in those settings. Our objective was to describe hospitalized Medicare beneficiaries with OUD, their post-acute care locations, and all-cause mortality and readmissions stratified by post-acute care location.

METHODS

We conducted a retrospective cohort study of acute hospitalizations using 2016-2018 Medicare Provider Analysis and Review (MedPAR) files linked to Medicare enrollment data and the Residential History File (RHF) for 100% of Medicare fee-for-service beneficiaries. The RHF which provides a person-level chronological history of health service utilization and locations of care was used to identify hospital discharge locations. We used ICD-10 codes for opioid dependence or "abuse" to identify OUD diagnoses from the MedPAR file. We conducted logistic regression to identify factors associated with discharge to an institutional setting versus home adjusting for demographics, comorbidities, and hospital stay characteristics.

RESULTS

Our analysis included 459,763 hospitalized patients with OUD. Of these, patients aged < 65 years and those dually enrolled in Medicaid comprised the majority (59.1%). OUD and opioid overdose were primary diagnoses in 14.3% and 6.2% of analyzed hospitalizations, respectively. We found that 70.3% of hospitalized patients with OUD were discharged home, 15.8% to a skilled nursing facility (SNF), 9.6% to a non-SNF institutional facility, 2.5% home with home health services, and 1.8% died in-hospital. Within 30 days of hospital discharge, rates of readmissions and mortality were 29.7% and 3.9%; respectively, with wide variation across post-acute locations. Factors associated with greater odds of discharge to institutional settings were older age, female sex, non-Hispanic White race and ethnicity, dual enrollment, longer hospital stay, more comorbidities, intensive care use, surgery, and primary diagnoses including opioid or other drug overdoses, fractures, and septicemia.

CONCLUSIONS

More than one-quarter (25.8%) of hospitalized Medicare beneficiaries with OUD received post-acute care in a setting other than home. High rates and wide variation in all-cause readmissions and mortality within 30 days post-discharge emphasize the need for improved post-acute care for people with OUD.

Characteristics, utilization, and concentration of outpatient care for dual-eligible Medicare beneficiaries

OBJECTIVES

To characterize the (1) distribution of outpatient care for dual-eligible Medicare beneficiaries ("duals") and (2) intensity of outpatient care utilization of duals vs non-dual-eligible beneficiaries ("nonduals").

STUDY DESIGN

Using data preceding the introduction of several outpatient alternative payment models, as well as Medicaid expansion, we evaluated the distribution of outpatient care across physician practices using a Lorenz curve and compared utilization of different outpatient services between duals and nonduals.

METHODS

We defined practices that did (high dual) and did not (low dual and no dual) account for the large majority of visits based on the Lorenz curve and then performed descriptive statistics between these groups of practices. Practice-level outcomes included patient demographics, practice characteristics, and county measures of structural disadvantage and population health. Patient-level outcomes included number of outpatient visits and unique outpatient physicians, primary vs subspecialty care visits, and expenditures.

RESULTS

Nearly 80% of outpatient visits for duals were provided by 35% of practices. Compared with low-dual and no-dual practices, high-dual practices served more patients (1117.6 patients per high-dual practice vs 683.8 patients per low-dual practice and 447.5 patients per no-dual practice; P < .001) with more comorbidities (3.9 mean total Elixhauser comorbidities among patients served by high-dual practices vs 3.6 among low-dual practices and 3.3 among no-dual practices; P < .001). With regard to utilization, duals had 2 fewer outpatient visits per year compared with nonduals (13.3 vs 15.2; P < .001), with particularly fewer subspecialty care visits (6.5 vs 7.9; P < .001) despite having more comorbidities (3.5 vs 2.7; P < .001).

CONCLUSIONS

Outpatient care for duals was concentrated among a small number of practices. Despite having more chronic conditions, duals had fewer outpatient visits. Duals and the practices that serve them may benefit from targeted policies to promote access and improve outcomes.

Post-fracture rehabilitation pathways and association with mortality among adults with cerebral palsy

OBJECTIVE

Rehabilitation may mitigate the high mortality rates and health declines post-fracture for adults with cerebral palsy, but this is understudied. The objectives were to characterize the post-fracture rehabilitation pathways and identify their association with 1-year survival among adults with cerebral palsy.

METHODS

A retrospective cohort study of adults with cerebral palsy with a fragility fracture with continuous health plan enrollment ≥1-year prior to and ≥1 day after their fracture date was performed using a random 20% Medicare fee-for-service dataset. Participants were categorized as a home discharge or inpatient rehabilitation admission post-fracture. For the home discharge cohort, weekly exposure to outpatient physical/occupational therapy (PT/OT) was examined up to 6-month post-fracture. Cox regression examined the association between time-varying PT/OTuse within 6-month post-fracture and mortality from 30 days to 1-year post-fracture before and after adjusting for confounders (e.g. medical complexity).

RESULTS

Of 3598 adults with cerebral palsy with an incident fragility fracture, 74% were discharged home without inpatient rehabilitation; they were younger, but more medically complex compared to the 26% admitted to inpatient rehabilitation. Among the home discharge cohort (n = 2662), 43.1% initiated PT/OTwithin 6-month post-fracture, and cumulative PT/OTexposure post-fracture was associated with improved survival; for example, per 3 weeks of PT/OTexposure, the adjusted mortality rate was 40% lower (95% confidence interval (CI) = 0.41-0.89).

CONCLUSIONS

Most adults with cerebral palsy with a fragility fracture were discharged home rather than to inpatient rehabilitation, and only 43.1% of that group initiated outpatient PT/OTwithin 6 months post-fracture. Receiving outpatient PT/OTwas associated with improved 1-year survival.

Costs of multimorbidity: a systematic review and meta-analyses

BACKGROUND

Multimorbidity is a rising global phenomenon, placing strains on countries' population health and finances. This systematic review provides insight into the costs of multimorbidity through addressing the following primary and secondary research questions: What evidence exists on the costs of multimorbidity? How do costs of specific disease combinations vary across countries? How do multimorbidity costs vary across disease combinations? What "cost ingredients" are most commonly included in these multimorbidity studies?

METHODS

We conducted a systematic review (PROSPERO: CRD42020204871) of studies published from January 2010 to January 2022, which reported on costs associated with combinations of at least two specified conditions. Systematic string-based searches were conducted in MEDLINE, The Cochrane Library, SCOPUS, Global Health, Web of Science, and Business Source Complete. We explored the association between costs of multimorbidity and country Gross Domestic Product (GDP) per capita using a linear mixed model with random intercept. Annual mean direct medical costs per capita were pooled in fixed-effects meta-analyses for each of the frequently reported dyads. Costs are reported in 2021 International Dollars (I$).

RESULTS

Fifty-nine studies were included in the review, the majority of which were from high-income countries, particularly the United States. (1) Reported annual costs of multimorbidity per person ranged from I$800 to I$150,000, depending on disease combination, country, cost ingredients, and other study characteristics. (2) Our results further demonstrated that increased country GDP per capita was associated with higher costs of multimorbidity. (3) Meta-analyses of 15 studies showed that on average, dyads which featured Hypertension were among the least expensive to manage, with the most expensive dyads being Respiratory and Mental Health condition (I$36,840), Diabetes and Heart/vascular condition (I$37,090), and Cancer and Mental Health condition in the first year after cancer diagnosis (I$85,820). (4) Most studies reported only direct medical costs, such as costs of hospitalization, outpatient care, emergency care, and drugs.

CONCLUSIONS

Multimorbidity imposes a large economic burden on both the health system and society, most notably for patients with cancer and mental health condition in the first year after cancer diagnosis. Whether the cost of a disease combination is more or less than the additive costs of the component diseases needs to be further explored. Multimorbidity costing studies typically consider only a limited number of disease combinations, and few have been conducted in low- and middle-income countries and Europe. Rigorous and standardized methods of data collection and costing for multimorbidity should be developed to provide more comprehensive and comparable evidence for the costs of multimorbidity.

Americans Aging With Disabilities Are More Likely to Have Multiple Chronic Conditions

Using data from the 2010 to 2017 National Health Interview survey, bivariate and multivariate regression analyses were utilized to estimate the percentage and odds of having multiple chronic conditions (two or more, three or more) among U.S. adults ages 65 and over with and without disabilities, controlling for sociodemographic factors and presence of psychological distress. Older adults with and without disabilities in the United States most frequently reported having hypertension, arthritis, and diabetes. Regression results indicate that older adults with disabilities are significantly more likely to experience two or more and three or more chronic conditions than older adults without disabilities, controlling for sociodemographic factors and health behaviors. These findings highlight a need for improvement in coordinated care that considers both disability and multiple chronic conditions in the management of patient health to support well-being in aging.

Healthcare Access and Utilization for Young Adults With Disability: U.S., 2014-2018

PURPOSE

Young adults with disability experience barriers to healthcare access and are at risk for not receiving needed services as they transition from pediatric to adult health systems. This study examined patterns of healthcare utilization for young adults with disability and potential barriers to receipt of care.

METHODS

Data from the 2014 to 2018 National Health Interview Survey were analyzed to examine differences in service utilization, unmet need, care satisfaction, and financial worry between young adults (18-30 years) with and without disability (unweighted n = 15,710). Odds ratios were adjusted for individual, family, and interview characteristics.

RESULTS

Compared to those without disability, young adults with disability were more likely to have had an emergency room visit in the past year (39.2% vs. 19.5%). They were also more likely to have a usual source of care when sick (82.2% vs. 75%). Among young adults who affirmed they had a usual place of care, those with disability were more likely to use the emergency room as their usual place of care (5.3% vs. 1.8%). A greater percentage of young adults with disability delayed medical care due to cost (19.1% vs. 8.9%) and reported an unmet medical need (21% vs. 10.2%).

CONCLUSIONS

Findings highlight gaps in healthcare access for young adults with disability. Differences in healthcare utilization patterns for young adults with disability and factors that may negatively influence health outcomes for this population were found. Further research focused on the continuity of healthcare services in this age group through the healthcare transition period may provide additional insight into these discrepancies.

Health Disparities Attributed to Medicare-Medicaid Dual-Eligible Status in Patients with Peripheral Arterial Disease

OBJECTIVE

Peripheral arterial disease (PAD) is a prevalent and debilitating disease that can be effectively treated by surgical revascularization. However, Medicare-Medicaid dual-eligible patients experience worse long-term outcomes, notably higher rates of amputation and mortality, relative to other insurance groups. This study aims to investigate how insurance status may perpetuate health disparities in PAD outcomes.

METHODS

The National Inpatient Sample was queried from 2000 to 2011 for patients ≥18 years with PAD who underwent surgical revascularization with hospitalization. Patients were stratified by insurance, and dual-eligibles were compared to Medicare-only, Medicaid-only, private insurance, and self-pay patients. Multivariable regression analysis was performed to assess the effect of dual-eligible status on postoperative outcomes such as inpatient mortality, complications, and favorable discharge (home or home with services).

RESULTS

A total of 771,790 hospitalizations were included in the analysis and stratified according to insurance type. Dual-eligible patients had the highest rates of major (32%) and extreme (11%) severity of illness and the highest rates of major (19%) and extreme (6%) risk of mortality among all insurance groups (p<0.001). Dual-eligibility status was independently associated with reduced odds of favorable discharge relative to all patients (p<0.001) and increased length of stay relative to Medicare-only (p=0.002) and private-payor groups (p<0.001). While dual-eligible patients had increased mortality odds relative to Medicaid-only and self-pay groups, they did not have significantly different odds of perioperative complications relative to all other insurance groups.

CONCLUSIONS

Medicare-Medicaid dual-eligible patients with PAD had more severe clinical presentations, a greater risk of extended hospitalizations, and a lower likelihood of being discharged home, relative to patients without dual-eligibility. Further studies are needed to examine the link between discharge disposition and disparities in health outcomes, as well as investigate interventions that effectively address the increased severity of PAD in dual-eligible patients.

Pregnancy-related outcomes among women with physical disabilities: A systematic review

BACKGROUND

Disability among women of reproductive age is common; many of these women desire children and do not have impaired fertility.

OBJECTIVES

To examine the epidemiological literature on perinatal health outcomes among women with physical disabilities.

DATA SOURCES

We searched Medline and CINAHL for articles published January 2009-April 2020 following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

STUDY SELECTION AND DATA EXTRACTION

Eligible studies were observational, quantitative, and reported on physical disabilities in association with prenatal, perinatal, postpartum, and/or infant health outcomes. We included studies that grouped physical and non-physical disabilities, such as surveys that queried only about general daily life limitations. We excluded case reports, descriptive studies without comparison groups, and studies conducted in low- or middle-income countries. Data extraction was done using predefined data fields.

SYNTHESIS

All authors were involved in screening activities, data extraction, and/or quality assessment (rating and areas for bias).

RESULTS

A total of 2650 articles were evaluated, of which sixteen met inclusion criteria (8 cross-sectional studies and 8 retrospective cohort studies). Assessments of disability status and perinatal outcomes widely varied across studies. Studies were rated as poor (n = 8) or fair quality (n = 8). Findings suggested that women with physical disabilities were at risk of several adverse outcomes, including caesarean delivery, infections, preterm complications, and maternal post-delivery hospitalisations, while their infants may be at risk of low birthweight and small-for-gestational age. Women classified as having complex/severe disabilities were often observed to be at higher risk of adverse outcomes compared to women with less severe disabilities.

CONCLUSIONS

Research assessing how physical, functional, and medical restrictions influence health outcomes among women with physical disabilities, from preconception through postpartum, is limited. Longitudinal studies with comprehensive data collection that accurately identify women with physical disabilities are critical to understanding their reproductive health risks and outcomes.

Differences in Multimorbidity among Cisgender Sexual Minority and Heterosexual Adults: Investigating Differences across Age-Groups

Objectives: Despite increased risk for chronic disease, there is limited research that has examined disparities in multimorbidity among sexual minority adults and whether these disparities differ by age. Methods: Data were from the 2014-2018 Behavioral Risk Factor Surveillance System. We used sex-stratified multinomial logistic regression to examine differences in multimorbidity between sexual minority and heterosexual cisgender adults and whether hypothesized differences varied across age-groups. Results: The sample included 687,151 adults. Gay, lesbian, and bisexual adults had higher odds of meeting criteria for multimorbidity than same-sex heterosexual adults. These disparities were greater among sexual minority adults under the age of 50 years. Only other non-heterosexual men over the age of 50 years and lesbian women over the age of 80 years were less likely to have multimorbidity than their same-sex heterosexual counterparts. Discussion: Health promotion interventions to reduce adverse health outcomes among sexual minorities across the life span are needed.

Relationship Between Different Risk Factor Patterns and Follow-Up Outcomes in Patients With ST-Segment Elevation Myocardial Infarction

Objective: Few studies have been concerned with the combined influences of the presence of multiple risk factors on follow-up outcomes in AMI patients. Our study aimed to identify risk factor patterns that may be associated with 1-year survival in male patients with ST-segment elevation myocardial infarction (STEMI). Methods: Data were from the China STEMI Care Project Phase 2 (CSCAP-2) collected between 2015 and 2018. A total of 15,675 male STEMI patients were enrolled in this study. Risk factor patterns were characterized using latent class analysis (LCA) according to seven risk factors. Associations between risk factor patterns and follow-up outcomes, including the incidence of major adverse cardiovascular and cerebrovascular events (MACCE) and all-cause death, were investigated by Cox proportional hazard regression analysis. Results: We obtained four risk factor patterns as "young and middle-aged with low levels of multimorbidity," "middle-aged with overweight," "middle-aged and elderly with normal weight," and "elderly with high multimorbidity." Four patterns had significant differences in event-free survival (P < 0.001). As compared with the patients of "young and middle-aged with low levels of multimorbidity" pattern, the risk of incidence of MACCE and all-cause death were increased in patients of "middle-aged with overweight" pattern (All-cause death: HR = 1.70, 95% CI:1.29~2.23; MACCE: HR = 1.49, 95% CI:1.29~1.72), "middle-aged and elderly with normal weight" pattern (All-cause death: HR = 3.04, 95% CI: 2.33~3.98; MACCE: HR = 1.82, 95% CI: 1.56~2.12), and "elderly with high multimorbidity" pattern (All-cause death: HR = 5.78, 95% CI: 4.49~7.42; MACCE: HR = 2.67, 95% CI: 2.31~3.10). Conclusions: By adopting a Latent Class Analysis Approach, STEMI patients can be characterized into four risk factor patterns with significantly different prognosis. The data is useful for the improvement of community health management in each specific subgroup of patients, which indicates a particular risk factor pattern.

Healthcare Decision-Making Among Dual-Eligible Immigrants: Implications from a Study of an Integrated Medicare-Medicaid Demonstration Program in California

To improve the coordination of long-term services and supports for dual-eligibles (those with both Medicare and Medicaid), California created Cal MediConnect (CMC), an Affordable Care Act-authorized managed care demonstration program. Beneficiaries were "passively enrolled" into CMC, meaning they were automatically enrolled unless they actively opted out. The aim of this study was to examine differences in factors influencing the enrollment decisions of U.S. born and immigrant dual-eligible beneficiaries. To explore differences in decision-making processes, we conducted in-depth interviews with dual-eligible consumers (39 native and 14 immigrant) in Los Angeles County. Interviews were analyzed using a constructivist grounded theory approach. Our findings illustrate a heightened sense of vulnerability and disempowerment experienced by immigrant participants. Immigrant participants also faced greater challenges in accessing healthcare and eliciting healthcare information compared to U.S.-born participants. Understanding the diverse perspectives of dual-eligible immigrant healthcare decision-making has implications for health care reform strategies aimed at ameliorating disparities for vulnerable immigrant populations.

Assessment of the Patient Protection and Affordable Care Act's Increase in Fees for Primary Care and Access to Care for Dual-Eligible Beneficiaries

IMPORTANCE

The Patient Protection and Affordable Care Act (ACA) temporarily increased primary care practitioners' (PCP) Medicaid fees to that of Medicare for 2013 to 2014 (fee bump) to help accommodate potential increases in demand for care with ACA coverage expansion. This also increased fees for PCPs treating dual-eligible Medicare and Medicaid beneficiaries in many states and eliminated payment differentials for dual-eligible vs non-dual-eligible Medicare beneficiaries that could limit access to care.

OBJECTIVE

To examine the association between the ACA fee bump and primary care visits for dual-eligible Medicare and Medicaid beneficiaries.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study used a difference-in-difference design and Medicare claims data from 2012 to 2016 to compare changes in visit rates for full-subsidy dual-eligible Medicare and Medicaid beneficiaries vs non-dual-eligible Medicare beneficiaries with low income whose fees did not change. Changes were examined overall and separately in states with temporary, extended, or minimal fee increases for dual-eligible vs non-dual-eligible beneficiaries in 2013 to 2014 (mandatory bump) and 2015 to 2016 (postbump or bump extension) vs 2012 (prebump). The study used linear regression models with beneficiary fixed effects, adjusting for time-changing area and beneficiary characteristics. Statistical analysis was performed from February 2018 to November 2019.

EXPOSURE

ACA-mandated Medicaid fee bump.

MAIN OUTCOMES AND MEASURES

Primary care visits per 100 beneficiaries overall and visits billed by physicians vs nurse practitioners and physician assistants.

RESULTS

The study included 3 052 044 dual-eligible and non-dual-eligible beneficiaries in 2012; 1 516 534 (49.7%) were aged 65 years or younger, 1 797 556 (58.9%) were women, and 1 754 626 (57.5%) had non-Hispanic White race/ethnicity. Overall primary care visit rates for dual-eligible beneficiaries were unchanged or decreased slightly relative to non-dual-eligible beneficiaries during the fee bump (2013-2014) and the postbump or bump extension period (2015-2016) vs baseline. Compared with non-dual-eligible beneficiaries, visit rates with primary care physicians declined more uniformly for dual-eligible beneficiaries across state groups and time periods (difference-in-difference: -0.37 [95% CI, -0.43 to -0.32] visits per 100 beneficiaries in 2013-2014 vs 2012; P < .001; and difference-in-difference: -0.62 [95% CI, -0.68 to -0.56] visits per 100 beneficiaries in 2015-2016 vs 2012; P < .001), whereas visits with nurse practitioners and physician assistants increased over time (difference-in-difference: 0.11 [95% CI, 0.08 to 0.14] visits per 100 beneficiaries in 2013-2014 vs 2012; P < .001; and difference-in-difference: 0.46 [95% CI, 0.43 to 0.50] visits per 100 beneficiaries in 2015-2016 vs 2012; P < .001). These changes, however, were not associated with the timing of the payment changes.

CONCLUSIONS AND RELEVANCE

The ACA fee bump was not associated with increases in primary care visits for dual-eligible Medicare and Medicaid beneficiaries. Visits for dual-eligible beneficiaries with primary care physicians decreased after the ACA, a decrease that was partially offset by increases in visits with nonphysician clinicians.

The public health response to the COVID-19 pandemic for people with disabilities

With the rapidly changing landscape of the COVID-19 outbreak, how to best address the needs and continue to protect the health and well-being of people with disabilities (PwDs) is a global public health priority. In this commentary we identify three public health areas of ongoing need and offer possible strategies to address each. These areas include: the types of data that would help clarify risks for PwDs and help assure their safety long term; the prevention, treatment and mitigation measures for PwDs that are needed through the duration of the outbreak; and the issues of equity in access to and quality of medical care for PwDs. Because of the rapid nature of the public health response, it is critical to reassess and readjust our approach to best address the needs of PwDs in the months and years to come and to incorporate these new practices into future emergency preparedness responses.

State variation in the characteristics of Medicare-Medicaid dual enrollees: Implications for risk adjustment

OBJECTIVE

To examine between-state differences in the socioeconomic and health characteristics of Medicare beneficiaries dually enrolled in Medicaid, focusing on characteristics not observable to or used by policy makers for risk adjustment.

DATA SOURCE

2010-2013 Medicare Current Beneficiary Survey.

STUDY DESIGN

Retrospective analyses of survey-reported health and socioeconomic status (SES) measures among low-income Medicare beneficiaries and low-income dual enrollees. We used hierarchical linear regression models with state random effects to estimate the between-state variation in respondent characteristics and linear models to compare the characteristics of dual enrollees by state Medicaid policies.

PRINCIPAL FINDINGS

Between-state differences in health and socioeconomic risk among low-income Medicare beneficiaries, as measured by the coefficient of variation, ranged from 17.5 percent for an index of socioeconomic risk to 20.3 percent for an index of health risk. Between-state differences were comparable among the subset of low-income beneficiaries dually enrolled in Medicare and Medicaid. Dual enrollees with incomes below the Federal Poverty Level were in better health and had higher SES in states that offered Medicaid to individuals with relatively higher incomes. Duals' average incomes were higher in states with Medically Needy programs.

CONCLUSIONS

Characteristics of dual enrollees differ substantially across states, reflecting differences in states' low-income Medicare populations and Medicaid policies. Risk-adjustment methods using dual enrollment to proxy for poor health and low SES should account for this state-level heterogeneity.

Practices Caring For The Underserved Are Less Likely To Adopt Medicare's Annual Wellness Visit

In 2011 Medicare introduced the annual wellness visit to help address the health risks of aging adults. The visit also offers primary care practices an opportunity to generate revenue, and may allow practices in accountable care organizations to attract healthier patients while stabilizing patient-practitioner assignments. However, uptake of the visit has been uneven. Using national Medicare data for the period 2008-15, we assessed practices' ability and motivation to adopt the visit. In 2015, 51.2 percent of practices provided no annual wellness visits (nonadopters), while 23.1 percent provided visits to at least a quarter of their eligible beneficiaries (adopters). Adopters replaced problem-based visits with annual wellness visits and saw increases in primary care revenue. Compared to nonadopters, adopters had more stable patient assignment and a slightly healthier patient mix. At the same time, visit rates were lower among practices caring for underserved populations (for example, racial minorities and those dually enrolled in Medicaid), potentially worsening disparities. Policy makers should consider ways to encourage uptake of the visit or other mechanisms to promote preventive care in underserved populations and the practices that serve them.

Provider continuity and reasons for not having a provider among persons with and without disabilities

BACKGROUND

Persons with disabilities experience health disparities while having usual providers more frequently than persons without disabilities. Provider discontinuity may help to explain these paradoxical findings, but research on the topic is nascent.

OBJECTIVE

To provide initial insight into whether persons with disabilities more frequently experience provider discontinuity than persons without disabilities.

METHODS

Pooled 2-year data from panels 14-16 (2009-2012) of the Medical Expenditure Panel Survey were examined. Working-age adults (18-64) were categorized as having no disability, basic disabilities, or complex disabilities. Persons were categorized having provider continuity (provider throughout the period) or discontinuity (gaining or losing providers during the period). χ² and multinomial logistic regressions were used to examine outcomes by disability status.

RESULTS

Persons with complex disabilities more frequently experienced continuity (83.7%) than persons without disabilities and those with basic disabilities (60.7% and 65.6%, respectively, p < 0.001). Seldom or never being sick was the most frequently reported reason for not having a usual provider; more persons without disabilities (64%) reported this reason than persons with disabilities (basic: 41.9%, p < 0.001; complex: 26.6%, p = 0.001). Persons with disabilities more frequently reported visiting different providers for different needs and not having a usual provider due to the costs of medical care than persons without disabilities.

CONCLUSIONS

Future research needs to examine the influence of continuity on healthcare disparities among persons with complex disabilities. Policies and practice must be attentive to how proposed changes to the healthcare system potentially reduce access to care among persons with disabilities.

The Otago Exercise Program: Innovative Delivery Models to Maximize Sustained Outcomes for High Risk, Homebound Older Adults

Background

It is estimated one in two adults age 80 and over fall each year, resulting in substantial morbidity and mortality rates among this oldest-old population. The Otago Exercise program (OEP) is an evidence-based fall prevention program shown to reduce falls by 35% among high-risk older adults. The OEP was designed to be delivered in the home by physical therapists. This model has encountered multiple implementation challenges in the United States health-care system, which has resulted in the development and testing of innovative models to support a broader reach and dissemination of this program.

Methods

The Northwest Senior and Disability Services is an Area Agency on Aging (AAA) serving a five-county region in Oregon. This AAA developed a model where a Certified Occupational Therapy Assistant (COTA) and exercise physiologist delivered the OEP with a physical therapist available to consult on all cases. Physical function assessments and self-reported perceptions about physical function were collected at baseline and 6 months.

Results

Baseline measures were collected on 239 participants enrolled in the OEP, and 62 participants at 6 months. Those who completed 6 months of the OEP demonstrated significant improvements in all physical function assessments and self-perceived functional improvements. A subset of this group that demonstrated improvements in the ability to rise from a chair also reported significantly fewer falls during the 6-month intervention.

Conclusion

Innovative models in which the OEP exercise sessions are delivered by non-physical therapists appear to be effective in improving physical performance measures and decreasing fall risk over a 6-month period. Because these models do not require a physical therapist, they may require fewer resources to implement. These findings have implications to inform implementation and dissemination strategies to bring the OEP to scale.

Geographic Variation in Use of Vestibular Testing among Medicare Beneficiaries

Objective

There is a lack of consensus regarding the indications for vestibular testing in the evaluation of dizziness and balance disorders. Geographic variation in health services utilization is associated with lack of consensus. To understand the variation in current practice, we investigated the patterns of use of vestibular testing and diagnosis codes for dizziness and balance disorders among individuals ≥65 years of age across different regions of the United States.

Study Design

Cross-sectional study.

Setting

Medicare administrative claims data.

Subjects and Methods

Using the Summarized Denominator file, a sample of the US population linked to the Surveillance, Epidemiology, and End Results (SEER)–Medicare files (years 2000-2010), we identified persons who were ≥65 years of age. We used multivariable analyses to determine the factors associated with vestibular testing and diagnoses.

Results

Of the 231,984 eligible Medicare beneficiaries, 27% were diagnosed with dizziness and balance disorders. Patterns of use of vestibular tests (eye movement recording for spontaneous nystagmus, caloric testing, and rotary chair testing) varied significantly by geographic region. Rotary chair test utilization varied most. We found significant geographic variation in vestibular testing and diagnoses after controlling for age, sex, race, Medicaid participation, and rurality.

Conclusions

There may be opportunities to improve the consistency and efficiency of care for dizziness and balance disorders. It will be important to define appropriate levels of vestibular diagnostic testing and which tests add sufficient value to justify the costs. Further work is needed to better characterize the causes and consequences of variation in vestibular test utilization.

Frequency of Disparities in Laboratory Testing After Statin Initiation in Subjects ≥65 Years

Laboratory testing is important for the safety of older adults initiating statins, but there has been little examination of laboratory testing disparities by race/ethnicity, age, gender, Medicaid eligibility, and multimorbidity. The study's purpose was to examine disparities in guideline-concordant baseline laboratory testing and abnormal laboratory values among a retrospective cohort of 76,868 Medicare fee-for-service beneficiaries from 10 states in the eastern United States who had dyslipidemia and initiated a statin from July 1 to November 30, 2011. Guideline-concordant assessment of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) was defined as evidence of an outpatient claim for either test within 180 days before or 14 days after the date of the index statin fill. In 2011, baseline laboratory testing rates were 89.3% for ALT and 88.8% for AST. Older adults were somewhat more likely to have ALT and AST testing if they were dually enrolled in Medicaid (relative risk 1.01, 95% confidence interval [CI] 1.00 to 1.02) or had multiple chronic conditions (relative risk 1.03, 95% CI 1.00 to 1.06 for 2 to 3 conditions; odds ratio [OR] 1.08, 95% CI 1.05 to 1.11 for 4 to 5 conditions; OR 1.14, 95% CI 1.11 to 1.17 for 6+ conditions), compared with 0 to 1 conditions. Non-Hispanic blacks were less likely to receive baseline testing (OR 0.97, 95% CI 0.96 to 0.98) than non-Hispanic Whites, and male beneficiaries were somewhat less likely to receive testing than female beneficiaries (OR 0.99, 95% CI 0.98 to 0.99). Abnormal values were rare. In conclusion, ALT and AST assessment after statin initiation was commonly done as recommended, and there were negligible disparities in testing rates for beneficiaries.

Multimorbidity in chronic disease: impact on health care resources and costs

Effective and resource-efficient long-term management of multimorbidity is one of the greatest health-related challenges facing patients, health professionals, and society more broadly. The purpose of this review was to provide a synthesis of literature examining multimorbidity and resource utilization, including implications for cost-effectiveness estimates and resource allocation decision making. In summary, previous literature has reported substantially greater, near exponential, increases in health care costs and resource utilization when additional chronic comorbid conditions are present. Increased health care costs have been linked to elevated rates of primary care and specialist physician occasions of service, medication use, emergency department presentations, and hospital admissions (both frequency of admissions and bed days occupied). There is currently a paucity of cost-effectiveness information for chronic disease interventions originating from patient samples with multimorbidity. The scarcity of robust economic evaluations in the field represents a considerable challenge for resource allocation decision making intended to reduce the burden of multimorbidity in resource-constrained health care systems. Nonetheless, the few cost-effectiveness studies that are available provide valuable insight into the potential positive and cost-effective impact that interventions may have among patients with multiple comorbidities. These studies also highlight some of the pragmatic and methodological challenges underlying the conduct of economic evaluations among people who may have advanced age, frailty, and disadvantageous socioeconomic circumstances, and where long-term follow-up may be required to directly observe sustained and measurable health and quality of life benefits. Research in the field has indicated that the impact of multimorbidity on health care costs and resources will likely differ across health systems, regions, disease combinations, and person-specific factors (including social disadvantage and age), which represent important considerations for health service planning. Important priorities for research include economic evaluations of interventions, services, or health system approaches that can remediate the burden of multimorbidity in safe and cost-effective ways.

Treatment of elderly patients with metastatic renal cell carcinoma

The risk of developing renal cell carcinoma (RCC) increases with age, and given the constant gain in life expectancy of the general population, both localized RCC and metastatic RCC (mRCC) are more frequently observed in the elderly population. The elderly are a heterogeneous group of patients often characterized by the presence of comorbidities, different compliance to treatment and polypharmacy. Here we review the available data with the aim to analyze the safety and efficacy of new targeted therapies (TTs) in elderly mRCC patients. TTs seem to be effective in both older and younger patients, but elderly patients appear to show reduced tolerance to treatments compared to younger patients. Prospective trials are needed to better understand how to manage mRCC in elderly patients.

Examining access to care for younger vs. older dual-eligible adults living in the community

BACKGROUND

Recent state dual-eligible (Medicare and Medicaid) payment reform demonstrations have included groups of both working-age and older adults, but relatively little is known about how access to care varies between these two populations.

OBJECTIVES/HYPOTHESIS

To examine access to a usual source of care for younger and older dual-eligible adults, to analyze whether timely access to several types of care differed in these two populations, and to understand some of the underlying reasons for delayed care among younger and older dual-eligibles.

METHODS

Using observations pooled across calendar years 2003-2012 of the Medical Expenditure Panel Survey, this study conducted descriptive and multivariate analyses to examine access to care measures.

RESULTS

Younger dual-eligible adults were more likely to encounter problems with accessing medical care, dental care, and prescription medications than older dual-eligible adults. Both groups of dual-eligible adults reported that a lack of affordability, gaps in existing insurance coverage, and difficulty in getting to a provider's office were the most common reasons for delayed access to care.

CONCLUSIONS

A lack of affordability for medical care, dental care, and prescription medications suggests that high co-payments and cost sharing for some services may be deterring access to needed care. Younger dual-eligibles were more likely to encounter service coverage gaps than older dual-eligibles. States should monitor Medicare-Medicaid plans to confirm they have adequate provider networks.

Improving the Care of Dual Eligible Patients in Rural Federally Qualified Health Centers: The Impact of Care Coordinators and Clinical Pharmacists

BACKGROUND

Dual eligible persons are those covered by both Medicare and Medicaid. There were 9.6 million dual eligible persons in the United States and 82 000 in West Virginia in 2010. Dual eligibles are poorer, sicker, and more burdened with serious mental health conditions than Medicare or Medicaid patients as a whole. Their health care costs are significantly higher and they are more likely to receive fragmented ineffective care.

PURPOSE

To improve the care experience and health care outcomes of dual eligible patients by the expanded use of care coordinators and clinical pharmacists.

METHODS

During 2012, 3 rural federally qualified community health centers in West Virginia identified 200 dual eligible patients each. Those with hospitalizations received more frequent care coordinator contacts. Those on more than 15 chronic medications had drug utilization reviews with recommendations to primary care providers. Baseline measures included demographics, chronic diseases, total medications and Beers list medications, hospitalization, and emergency room (ER) use in the previous year. Postintervention measures included hospitalization, ER use, total medications, and Beers list medications.

RESULTS

Out of 556 identified patients, 502 were contacted and enrolled. Sixty-five percent were female. The median age was 69 years, with a range of 29 to 93 years. Nineteen percent (19%) of patients were on 15 or more medications, 56% on psychotropic medication, and 33% on chronic opiates. One site showed reductions of 34% in hospitalizations and 25% in ER visits during the intervention year. For all sites combined, there was a 5.5% reduction in total medications and a 14.8% reduction in Beers list medications.

CONCLUSIONS

A modest investment in care coordination and clinical pharmacy review can produce significant reductions in hospitalization and harmful polypharmacy for community dwelling dual eligible patients.

Systematic Review of Programs Treating High-Need and High-Cost People With Multiple Chronic Diseases or Disabilities in the United States, 2008-2014

Introduction

Finding ways to provide better and less expensive health care for people with multiple chronic conditions or disability is a pressing concern. The purpose of this systematic review was to evaluate different approaches for caring for this high-need and high-cost population.

Methods

We searched Medline for articles published from May 31, 2008, through June 10, 2014, for relevant studies. Articles were considered eligible for this review if they met the following criteria: included people with multiple chronic conditions (behavioral or mental health) or disabilities (2 or more); addressed 1 or more of clinical outcomes, health care use and spending, or patient satisfaction; and compared results from an intervention group with a comparison group or baseline measurements. We extracted information on program characteristics, participant characteristics, and significant (positive and negative) clinical findings, patient satisfaction, and health care use outcomes. For each outcome, the number of significant and positive results was tabulated.

Results

Twenty-seven studies were included across 5 models of care. Of the 3 studies reporting patient satisfaction outcomes, 2 reported significant improvements; both were randomized controlled trials (RCTs). Of the 14 studies reporting clinical outcomes, 12 reported improvements (8 were RCTs). Of the 13 studies reporting health care use and spending outcomes, 12 reported significant improvements (2 were RCTs). Two models of care — care and case management and disease management — reported improvements in all 3 outcomes. For care and case management models, most improvements were related to health care use. For the disease management models, most improvements were related to clinical outcomes.

Conclusions

Care and case management as well as disease management may be promising models of care for people with multiple chronic conditions or disabilities. More research and consistent methods are needed to understand the most appropriate care for these high-need and high-cost patients.

Global Multimorbidity Patterns: A Cross-Sectional, Population-Based, Multi-Country Study

BACKGROUND

Population ageing challenges health care systems due to the high prevalence and impact of multimorbidity in older adults. However, little is known about how chronic conditions present in certain multimorbidity patterns, which could have great impact on public health at several levels. The aim of our study was to identify and describe multimorbidity patterns in low-, middle-, and high-income countries.

METHODS

We analyzed data from the Collaborative Research on Ageing in Europe project (Finland, Poland, and Spain) and the World Health Organization's Study on Global Ageing and Adult Health (China, Ghana, India, Mexico, Russia, and South Africa). These cross-sectional studies obtained data from 41,909 noninstitutionalized adults older than 50 years. Exploratory factor analysis was performed to detect multimorbidity patterns. Additional adjusted binary logistic regressions were performed to identify associations between sociodemographic factors and multimorbidity.

RESULTS

Overall multimorbidity prevalence was high across countries. Hypertension, cataract, and arthritis were the most prevalent comorbid conditions. Two or three multimorbidity patterns were found per country. Several patterns were identified across several countries: "cardio-respiratory" (angina, asthma, and chronic obstructive pulmonary disease), "metabolic" (diabetes, obesity, and hypertension), and "mental-articular" (arthritis and depression).

CONCLUSIONS

A high prevalence of multimorbidity occurs in older adults across countries, with low- and middle-income countries gradually approaching the figures of richer countries. Certain multimorbidity patterns are present in several countries, which suggest that common underlying etiopathogenic factors may play a role. Deeper understanding of these patterns may lead to the development of preventive actions to diminish their prevalence and also give rise to new, comprehensive approaches for the management of these co-occurring conditions.

Diagnosis isn't enough: Understanding the connections between high health care utilization, chronic conditions and disabilities among U.S. working age adults

BACKGROUND

Under the ACA, new programs are being developed to enhance care coordination and reduce health care costs among people with chronic conditions, disabilities, and high utilization of health care. However, the relationships between these groups are not well understood.

OBJECTIVES

Our aims were to (1) identify high utilizers of health care in the U.S. working age (18-64) population, (2) examine the overlap between this group and people with chronic conditions and/or disabilities, (3) identify predictors of high service use or cost among these subpopulations, and (4) recommend approaches for stratification of individuals with high health care utilization.

METHODS

Using pooled national data from the Medical Expenditure Panel Survey (2006-2008), we created indices to identify elevated or high utilization and cost groups. We performed descriptive analyses, bivariate comparisons and multivariate analyses to examine the relations between these populations and individuals with chronic conditions and/or disabilities.

RESULTS

While the large majority of persons with high use/cost had chronic conditions, the minority of persons with chronic conditions had high health care utilization. However, among persons with chronic conditions, disability was a significant predictor of high utilization. Annual expenditures were significantly elevated among people with disabilities, particularly when activities of daily living were limited.

CONCLUSIONS

We conclude that medical diagnosis alone is insufficient for the development of eligibility criteria for, or the evaluation of, programs intended to better the delivery or coordination of services for high utilizers of health care services. New approaches are needed to assess functional limitations and identify ongoing needs for services and supports.

Educating Aging Service Agency Staff About Discussing End-of-Life Wishes

Seventy-five percent of Americans support the idea of Advance Directives (ADs) but less than 20% complete one, resulting in increased hospitalization costs, unwanted treatment, and difficult family decisions. Engaging community resources for public education may be effective for increasing understanding and completion of ADs. This project focused on workers in an agency serving older adults. A training program was developed with the goal of increasing their understanding of the process and benefits of Health Care Proxies (HCPs) and ADs through hands-on experience, increasing relevant skills and willingness to discuss with consumers, and to implement an agency protocol increasing documentation of HCPs for consumers. After a small proof-of-concept pilot, all staff members were asked to participate in the educational program. The pilot program delivery found increased staff knowledge as well as motivation to complete HCPs among the staff themselves and their own families. This program resulted in increased staff knowledge of EOL documents, willingness to engage in EOL discussions, and an increase in documented HCPs. This program has relevance for workers in other agencies as they engage older consumers to encourage completion of ADs. This experiential approach to staff education increased their understanding and willingness to initiate EOL discussion with consumers.

Efficacy and safety of sunitinib in elderly patients with metastatic renal cell carcinoma

Background:

We retrospectively analyzed sunitinib outcome as a function of age in metastatic renal cell carcinoma (mRCC) patients.

Methods:

Data were pooled from 1059 patients in six trials. Kaplan–Meier estimates of progression-free survival (PFS) and overall survival (OS) were compared by log-rank test between patients aged <70 (n=857; 81%) and ⩾70 (n=202; 19%) years.

Results:

In first-line patients, median PFS was comparable in younger and older patients, 9.9 vs 11.0 months, respectively (HR, 0.89; 95% CI: 0.73–1.09; P=0.2629), as was median OS, 23.6 vs 25.6 months (HR, 0.93; 95% CI: 0.74–1.18; P=0.5442). Similarly, in cytokine-refractory patients, median PFS was 8.1 vs 8.4 months (HR, 0.79; 95% CI: 0.49–1.28; P=0.3350), while median OS was 20.2 vs 15.8 months (HR, 1.14; 95% CI: 0.73–1.79; P=0.5657). Some treatment-emergent adverse events were significantly less common in younger vs older patients, including fatigue (60% vs 69%), cough (20% vs 29%), peripheral edema (17% vs 27%), anemia (18% vs 25%), decreased appetite (13% vs 29%), and thrombocytopenia (16% vs 25% all P<0.05). Hand–foot syndrome was more common in younger patients (32% vs 24%).

Conclusions:

Advanced age should not be a deterrent to sunitinib therapy and elderly patients may achieve additional clinical benefit.
