Addressing Health-Related Social Needs Via Community Resources: Lessons From Accountable Health Communities.

The Center for Medicare and Medicaid Innovation launched the Accountable Health Communities (AHC) Model in 2017 to assess whether identifying and addressing Medicare and Medicaid beneficiaries' health-related social needs reduced health care use and spending. We surveyed a subset of AHC Model beneficiaries with one or more health-related social needs and two or more emergency department visits in the prior twelve months to assess their use of community services and whether their needs were resolved. Survey findings indicated that navigation-connecting eligible patients with community services-did not significantly increase the rate of community service provider connections or the rate of needs resolution, relative to a randomized control group. Findings from interviews with AHC Model staff, community service providers, and beneficiaries identified challenges connecting beneficiaries to community services. When connections were made, resources often were insufficient to resolve beneficiaries' needs. For navigation to be successful, investments in additional resources to assist beneficiaries in their communities may be required.

Health Care Impacts Of Resource Navigation For Health-Related Social Needs In The Accountable Health Communities Model.

Social determinants of health can adversely affect health and therefore lead to poor health care outcomes. When it launched in 2017, the Accountable Health Communities (AHC) Model was at the forefront of US health policy initiatives seeking to address social determinants of health. The AHC Model, sponsored by the Centers for Medicare and Medicaid Services, screened Medicare and Medicaid beneficiaries for health-related social needs and offered eligible beneficiaries assistance in connecting with community services. This study used data from the period 2015-21 to test whether the model had impacts on health care spending and use. Findings show statistically significant reductions in emergency department visits for both Medicaid and fee-for-service Medicare beneficiaries. Impacts on other outcomes were not statistically significant, but low statistical power may have limited our ability to detect model effects. Interviews with AHC Model participants who were offered navigation services to help them find community-based resources suggested that navigation services could have directly affected the way in which beneficiaries engage with the health care system, leading them to be more proactive in seeking appropriate care. Collectively, findings provide mixed evidence that engaging with beneficiaries who have health-related social needs can affect health care outcomes.

Effects of Global Budget Payments on Vulnerable Medicare Subpopulations in Maryland.

There is little evidence regarding population equity in alternative payment models (APMs). We aimed to determine whether one such APM, the Maryland All-Payer Model (MDAPM), had differential effects on subpopulations of vulnerable Medicare beneficiaries. We utilized Medicare fee-for-service claims for beneficiaries living in Maryland and 48 comparison hospital market areas between 2011 and 2018. We used doubly robust difference-in-difference-in-differences regression models to estimate the differential effects of MDAPM on Medicare beneficiaries by dual eligibility for Medicare and Medicaid, disability as original reason for Medicare entitlement, presence of multiple chronic conditions (MCC), race, and rural residency status. Dual, disabled, and beneficiaries with MCC had greater reductions in expenditures and utilization than their counterparts. Hospitals may have prioritized high-cost, high-need patients as they changed their care delivery practices. The percentage of hospital discharges with 14-day follow-up was significantly lower for disadvantaged subpopulations, including duals, disabled, and non-White.

Patient-Centered Medical Home Activities Associated With Low Medicare Spending and Utilization.

PURPOSE: To identify components of the patient-centered medical home (PCMH) model of care that are associated with lower spending and utilization among Medicare beneficiaries. METHODS: Regression analyses of changes in outcomes for Medicare beneficiaries in practices that engaged in particular PCMH activities compared with beneficiaries in practices that did not. We analyzed claims for 302,719 Medicare fee-for-service beneficiaries linked to PCMH surveys completed by 394 practices in the Centers for Medicare & Medicaid Services' 8-state Multi-Payer Advanced Primary Care Practice demonstration. RESULTS: Six activities were associated with lower spending or utilization. Use of a registry to identify and remind patients due for preventive services was associated with all 4 of our outcome measures: total spending was $69.77 less per beneficiary per month (PBPM) (P = 0.00); acute-care hospital spending was $36.62 less PBPM (P = 0.00); there were 6.78 fewer hospital admissions per 1,000 beneficiaries per quarter (P1KBPQ) (P = 0.003); and 11.05 fewer emergency department (ED) visits P1KBPQ (P = 0.05). Using a patient registry for pre-visit planning and clinician reminders was associated with $29.31 lower total spending PBPM (P = 0.05). Engaging patients with chronic conditions in goal setting and action planning was associated with 4.62 fewer hospital admissions P1KBPQ (P = 0.01) and 11.53 fewer ED visits P1KBPQ (P = 0.00). Monitoring patients during hospital stays was associated with $22.06 lower hospital spending PBPM (P = 0.03). Developing referral protocols with commonly referred-to clinicians was associated with 11.62 fewer ED visits P1KBPQ (P = 0.00). Using quality improvement approaches was associated with 13.47 fewer ED visits P1KBPQ (P =0.00). CONCLUSIONS: Practices seeking to deliver more efficient care may benefit from implementing these 6 activities.

Maryland's Global Hospital Budgets: Impacts on Medicare Cost and Utilization for the First 3 Years.

BACKGROUND: Global budgets have been proposed as a way to control health care expenditures, but experience with them in the United States is limited. Global budgets for Maryland hospitals, the All-Payer Model, began in January 2014. OBJECTIVES: To evaluate the effect of hospital global budgets on health care utilization and expenditures. RESEARCH DESIGN: Quantitative analyses used a difference-in-differences design modified for nonparallel baseline trends, comparing trend changes from a 3-year baseline period to the first 3 years after All-Payer Model implementation for Maryland and a matched comparison group. SUBJECTS: Hospitals in Maryland and matched out-of-state comparison hospitals. Fee-for-service Medicare beneficiaries residing in Maryland and comparison hospital market areas. MEASURES: Medicare claims were used to measure total Medicare expenditures; utilization and expenditures for hospital and nonhospital services; admissions for avoidable conditions; hospital readmissions; and emergency department visits. Qualitative data on implementation were collected through interviews with senior hospital staff, state officials, provider organization representatives, and payers, as well as focus groups of physicians and nurses. RESULTS: Total Medicare and hospital service expenditures declined during the first 3 years, primarily because of reduced expenditures for outpatient hospital services. Nonhospital expenditures, including professional expenditures and postacute care expenditures, also declined. Inpatient admissions, including admissions for avoidable conditions, declined, but, there was no difference in the change in 30-day readmissions. Moreover, emergency department visits increased for Maryland relative to the comparison group. CONCLUSIONS: This study provides evidence that hospital global budgets as implemented in Maryland can reduce expenditures and unnecessary utilization without shifting costs to other parts of the health care system.

Changes in Utilization and Expenditures for Medicare Beneficiaries in Patient-centered Medical Homes: Findings From the Multi-Payer Advanced Primary Care Practice Demonstration.

BACKGROUND: Patient-centered medical homes are expected to reduce expenditures by increasing the use of primary care services, shifting care from inpatient to outpatient settings, and reducing avoidable utilization. Under the Multi-Payer Advanced Primary Care Practice (MAPCP) Demonstration, Medicare joined Medicaid and commercial payers in 8 states to support ongoing patient-centered medical home initiatives. OBJECTIVE: To evaluate the effects of the MAPCP Demonstration on health care utilization and expenditures for Medicare beneficiaries. RESEARCH DESIGN: We used difference-in-differences regression modeling to estimate changes in utilization and expenditures before and after the start of the MAPCP Demonstration, comparing beneficiaries engaged with MAPCP Demonstration practices to beneficiaries engaged with primary care practices that were not medical homes. Qualitative data collected during annual site visits provided contextual information on participating practices to inform interpretations of the demonstration outcomes. SUBJECTS: Fee-for-service Medicare beneficiaries attributed to MAPCP Demonstration practices or to comparison group practices. MEASURES: Medicare claims were used to measure total Medicare expenditures and utilization and expenditures for inpatient, emergency room, primary care, and specialist services. RESULTS: Despite the transformation of practices over the demonstration period, there was minimal evidence of a shift to more efficient utilization of health care services, and only 1 state saw a statistically significant reduction in total per-beneficiary expenditures. CONCLUSIONS: Although the MAPCP Demonstration did not have strong, consistent impacts on utilization and expenditures, this evaluation provides insights that may be useful for the design of future health care transformation models.

Reducing Inpatient Hospital and Emergency Room Utilization Among Nursing Home Residents.

OBJECTIVE: To examine the association among nursing home residents between strength of relationship with a primary care provider (PCP) and inpatient hospital and emergency room (ER) utilization. METHOD: Medicare administrative data for beneficiaries residing in a nursing home between July 2007 and June 2009 were used in multivariate analyses controlling for beneficiary, nursing home, and market characteristics to assess the association between two measures-percentage of months with a PCP visit and whether the patient maintained the same usual source of care after nursing home admission-and hospital admissions and ER visits for all causes and for ambulatory care sensitive conditions (ACSCs). RESULTS: Both measures of strength of patient-provider relationships were associated with fewer inpatient admissions and ER visits, except regularity of PCP visits and ACSC ER visits. DISCUSSION: Policy makers should consider increasing the strength of nursing home resident and PCP relationships as one strategy for reducing inpatient and ER utilization.

Primary care and specialty providers: an assessment of continuity of care, utilization, and expenditures.

BACKGROUND: Little is known as to whether medical home principles, such as continuity of care (COC), would have the same effect on health service use for individuals whose primary (or predominant) provider is a specialist instead of a primary care provider (PCP). OBJECTIVE: To test associations between health service use and expenditures and (1) beneficiaries' predominant provider type (PCP or specialist) and (2) COC among beneficiaries who primarily see a PCP and those who primarily see a specialist. RESEARCH DESIGN: This is a cross-sectional analysis of Medicare fee-for-service claims data from July 2007 to June 2009. Negative binomial and generalized linear models were used in multivariate regression modeling. SUBJECTS: The study cohort comprised 613,471 community-residing Medicare fee-for-service beneficiaries. MEASURES: Beneficiaries' predominant provider type and COC index during a baseline period (July 2007-June 2008) were studied. All-cause and ambulatory care sensitive condition (ACSC) hospitalizations and emergency department (ED) visits and related expenditures and total expenditures in a 1-year follow-up period (July 2008-June 2009) were also reported. RESULTS: Twenty-five percent of beneficiaries primarily saw a specialist. Having a specialist predominant provider was associated with 9% fewer ED visits, 14% fewer ACSC ED visits, and 8% fewer ACSC hospitalizations (all P<0.001). Regardless of whether the beneficiary's predominant provider was a specialist or a PCP, higher continuity was associated with fewer all-cause hospitalizations and ED visits and lower expenditures for these services. Higher continuity was also associated with lower total expenditures. CONCLUSIONS: Regardless of the predominant provider's specialty, greater continuity was associated with less use of high-cost services and lower expenditures for these services.

Impact of state-specific Medicaid reimbursement and eligibility policies on receipt of cancer screening.

BACKGROUND: Although state Medicaid programs cover cancer screening, Medicaid beneficiaries are less likely to be screened for cancer and are more likely to present with tumors of an advanced stage than are those with other insurance. The current study was performed to determine whether state Medicaid eligibility and reimbursement policies affect the receipt of breast, cervical, and colon cancer screening among Medicaid beneficiaries. METHODS: Cross-sectional regression analyses of 2007 Medicaid data from 46 states and the District of Columbia were performed to examine associations between state-specific Medicaid reimbursement/eligibility policies and receipt of cancer screening. The study sample included individuals aged 21 years to 64 years who were enrolled in fee-for-service Medicaid for at least 4 months. Subsamples eligible for each screening test were: Papanicolaou test among 2,136,511 patients, mammography among 792,470 patients, colonoscopy among 769,729 patients, and fecal occult blood test among 753,868 patients. State-specific Medicaid variables included median screening test reimbursement, income/financial asset eligibility requirements, physician copayments, and frequency of eligibility renewal. RESULTS: Increases in screening test reimbursement demonstrated mixed associations (positive and negative) with the likelihood of receiving screening tests among Medicaid beneficiaries. In contrast, increased reimbursements for office visits were found to be positively associated with the odds of receiving all screening tests examined, including colonoscopy (odds ratio [OR], 1.07; 95% confidence interval [95% CI], 1.06-1.08), fecal occult blood test (OR, 1.09; 95% CI, 1.08-1.10), Papanicolaou test (OR, 1.02; 95% CI, 1.02-1.03), and mammography (OR, 1.02; 95% CI, 1.02-1.03). Effects of other state-specific Medicaid policies varied across the screening tests examined. CONCLUSIONS: Increased reimbursement for office visits was consistently associated with an increased likelihood of being screened for cancer, and may be an important policy tool for increasing screening among this vulnerable population.

Cancer Screening Among U.S. Medicaid Enrollees with Chronic Comorbidities or Residing in Long-Term Care Facilities.

BACKGROUND: Ensuring appropriate cancer screenings among low-income persons with chronic conditions and persons residing in long-term care (LTC) facilities presents special challenges. This study examines the impact of having chronic diseases and of LTC residency status on cancer screening among adults enrolled in Medicaid, a joint state-federal government program providing health insurance for certain low-income individuals in the U.S. METHODS: We used 2000-2003 Medicaid data for Medicaid-only beneficiaries and merged 2003 Medicare-Medicaid data for dually-eligible beneficiaries from four states to estimate the likelihood of cancer screening tests during a 12-month period. Multivariate regression models assessed the association of chronic conditions and LTC residency status with each type of cancer screening. RESULTS: LTC residency was associated with significant reductions in screening tests for both Medicaid-only and Medicare-Medicaid enrollees; particularly large reductions were observed for receipt of mammograms. Enrollees with multiple chronic comorbidities were more likely to receive colorectal and prostate cancer screenings and less likely to receive Papanicolaou (Pap) tests than were those without chronic conditions. CONCLUSIONS: LTC residents have substantial risks of not receiving cancer screening tests. Not performing appropriate screenings may increase the risk of delayed/missed diagnoses and could increase disparities; however, it is also important to consider recommendations to appropriately discontinue screening and decrease the risk of overdiagnosis. Although anecdotal reports suggest that patients with serious comorbidities may not receive regular cancer screening, we found that having chronic conditions increases the likelihood of certain screening tests. More work is needed to better understand these issues and to facilitate referrals for appropriate cancer screenings.

Cancer Treatment for Dual Eligibles: What Are the Costs and Who Pays?

This study quantifies treatment costs for melanoma and breast, cervical, colorectal, lung, and prostate cancer among patients with dual Medicare and Medicaid eligibility. The analyses use merged Medicare and Medicaid Analytic eXtract enrollment and claims data for dually eligible beneficiaries age>18 in Georgia, Illinois, Louisiana, and Maine in 2003 (n=892,001). We applied ordinary least squares regression analysis to estimate annual expenditures attributable to each cancer after controlling for beneficiaries' age, race/ethnicity, sex, and comorbid conditions, and state fixed effects. Cancers and comorbid conditions were identified on the basis of diagnosis codes on insurance claims. The most prevalent cancers were prostate (38.4 per 1,000 men) and breast (30.7 per 1,000 women). Dual eligibles with the study cancers had higher rates of other chronic conditions such as hypertension and arthritis than other beneficiaries. Total Medicare and Medicaid expenditures for dual eligibles with the study cancers ranged from $30,328 for those with lung cancer to $17,011 for those with breast cancer, compared with $10,664 for beneficiaries without the cancers. However, only 9% to 30% of medical expenditures for dual eligibles with the study cancers were attributable to the cancer itself. In 2003, combined Medicare/Medicaid spending for dual eligibles attributable to the six cancers in the four study states exceeded $256 million ($314 million in 2012 dollars). Dual eligibles with these cancers also had high rates of other medical conditions. These comorbidities should be recognized, both in documenting cancer treatment costs and in developing programs and policies that promote timely cancer diagnosis and treatment.

What happens to children who lose public health insurance coverage?

Little is known about what happens to children who disenroll from public health-insurance programs. A telephone survey was conducted of children who recently had disenrolled from either Oregon's State Children's Health Insurance Program (SCHIP) or FHIAP (premium assistance) programs, both of which have identical eligibility requirements. Access for these disenrolled children was driven largely by health insurance coverage. Insured children were more likely to have a usual source of care and to have seen a physician when they needed one. While FHIAP-disenrolled children were more likely to have private health-insurance coverage than those leaving SCHIP, absolute levels were low (53 percent and 33 percent, respectively). Thus, these programs generally did not provide a bridge to nonsubsidized private health insurance. Despite higher incomes (the main reason for losing coverage), many families did not purchase private health insurance, presumably because they still could not afford to do so.

Premium subsidy programs: who enrolls, and how do they fare?

Little is known about who enrolls in state premium subsidy programs or enrollees' experiences. This study surveyed parents of children enrolled in two programs with identical income eligibility requirements: Oregon's State Children's Health Insurance Program (SCHIP) and its premium subsidy program (FHIAP). Parents choosing FHIAP were more likely to be employed, to speak English, to have prior experience with premiums and private health insurance, and to perceive insurance as protection against future health care needs. Despite copayment requirements and more restricted benefits in FHIAP, there were few differences in access to care between children enrolled in the two programs.

State payment limitations on Medicare cost-sharing: impact on dually eligible beneficiaries.

The Balanced Budget Act (BBA) of 1997 allowed states to limit how much their Medicaid programs contributed toward the Medicare cost-sharing liability of dually eligible beneficiaries. Policymakers have grown concerned that such limitations may affect access to care for these beneficiaries. We used a quasi-experimental design to analyze changes in access from 1996 to 1998, using Medicare and Medicaid data from nine states. Cost-sharing payments fell in six of the nine states following the BBA, and access to outpatient physician visits for dually eligible beneficiaries was reduced relative to non-dually eligible beneficiaries in those states.

Consequences of states' policies for SCHIP disenrollment.

Policymakers are concerned about disenrollment from the State Children's Health Insurance Program (SCHIP). We describe disenrollment in Florida, Kansas, New York, and Oregon and assess the links between disenrollment and States' SCHIP policies. We found that SCHIP is used on a long-term basis (at least 2 years) for a significant group of new enrollees and as temporary coverage (fewer than 12 months) for many others. Recertification generates large disenrollments (about one-half of children still enrolled at the time), but as many as 25 percent return within 2 months. The increased disenrollment rate at recertification is completely eliminated by a policy of passive re-enrollment.

Children in the Oregon Health Plan: how have they fared?

This study examines the impact of the Oregon Health Plan (OHP) on children's access to care. A telephone survey was conducted in 1998 of two groups of children: OHP enrollees and food stamp recipients not enrolled in OHP. Much of OHP's impact has been realized by the simple extension of health insurance coverage to Oregon's low-income children. The availability of insurance significantly increased the use of physician visits and dental care. The priority list had little effect on children, affecting only 2 percent of OHP children surveyed, most of whom succeeded in getting the service anyway. Thus, despite the negative publicity prior to its implementation, there is no evidence that "rationing" under OHP has substantially restricted access to needed services for children.

Impact of the Oregon Health Plan on access and satisfaction of adults with low income.

OBJECTIVE: To evaluate the effects of the Oregon Health Plan (OHP) on beneficiary access and satisfaction. DATA SOURCES: Telephone survey of nondisabled adults in 1998. STUDY DESIGN: Two groups of adults were surveyed: OHP enrollees and Food Stamp recipients not enrolled in OHP. The Food Stamp sample included both privately insured and uninsured recipients. This allowed us to disentangle the insurance effects of OHP from other effects such as its reliance on managed care and the priority list. OHP and Food Stamp adults were compared along the following measures: usual source of care, utilization of health care services, unmet need, and satisfaction with care. DATA COLLECTION: The survey was conducted by telephone, using computer-assisted telephone interviewing techniques. PRINCIPAL FINDINGS: Much of OHP's impact has been realized by its extension of health insurance coverage to Oregon's low-income residents. The availability of health insurance significantly increased the utilization of many health care services and reduced unmet need for care. OHP was associated within a higher percentage of enrollees having a usual source of care and higher rates of Pap test screening among women compared with Food Stamp recipients. OHP enrollees also reported significantly higher use of dental care and prescription drugs; use we attribute to the expanded benefit package under the priority list. At the same time, OHP enrollees reported a greater unmet need for prescription drugs. Drug treatment for below-the-line conditions was one reason for this unmet need, but often the specific drug simply was not in the plan's formulary. OHP enrollees were as satisfied with their health care as those Food Stamp recipients with private health insurance. CONCLUSIONS: Despite the negative publicity prior to its implementation, there is no evidence that "rationing" under OHP's priority list has substantially restricted access to needed services. OHP adults appear to enjoy access equal to or better than that of low-income persons with private health insurance and have far greater access than the uninsured.

Covering Uninsured Adults Through Medicaid: Lessons from the Oregon Health Plan.

The Oregon Health Plan (OHP), Oregon's section 1115 Medicaid waiver program, expanded eligibility to all residents living below poverty. We use survey data, as well as OHP administrative data, to profile the expansion population and to provide lessons for other States considering such programs. OHP's eligibility expansion has proved a successful vehicle for covering large numbers of uninsured adults, although most beneficiaries enroll for only a brief period of time. The expansion population, particularly childless adults, is relatively sick and has high service use rates. Beneficiaries are also likely to enroll when they are in need of care.
