Does Home- and Community-Based Care Affect Nursing Home Use?

A study was conducted to assess change in numbers, expenditures, and case mix of nursing home residents as Medicaid investment in home- and community-based services (HCBS) 1915(c) waivers increased in seven states. The seven states provided Medicaid expenditure and utilization data from 2001 to 2005, including waiver and state plan utilization. The Minimum Data Set was used for nursing home residents. For three states, community assessment data were also used. In six states, the number of nursing home clients decreased as the numbers of HCBS clients grew. However, in most states, the number of additional waiver clients often greatly exceeded reductions in nursing home residents. Nursing home payments decreased moderately, but this decrease was offset by increases in HCBS waiver and state plan expenditures, leading to a net increase in long-term support services (LTSS) expenditures from 2001 to 2005. Increases in waiver expenditures outpaced increases in waiver clients, indicating expansion of services on top of expansion in clients. States that showed substantial increases in HCBS showed only modest increases in nursing home case mix. The case mix for nursing home residents was more acute than that for HCBS users. The expectation that greater HCBS use would siphon off less severe LTSS users and hence lead to a higher case mix in nursing homes was partially met. The more acute case mix in nursing homes suggests that HCBS serves some individuals who were previously cared for in nursing homes but many who were not. Efforts to promote substitution of HCBS for institutional care will require more proactive strategies such as diversion.

Innovative Oncology Care Models Improve End-Of-Life Quality, Reduce Utilization And Spending

Three models that received Health Care Innovation Awards from the Centers for Medicare and Medicaid Services (CMS) aimed to reduce the cost and use of health care services and improve the quality of care for Medicare beneficiaries with cancer. Each emphasized a different principle: the oncology medical home, patient navigation, or palliative care. Comparing participants in each model who died during the study period to matched comparators, we found that the oncology medical home and patient navigation models were associated with decreased costs in the last ninety days of life (

The patient navigation model was also associated with fewer emergency department visits in the last thirty days of life and increased hospice enrollment in the last two weeks of life. These promising results can inform new initiatives for cancer patients, such as the CMS Oncology Care Model.

Emergency department utilization as a measure of physician performance.

PURPOSE Little is known about mental health disorders (MHDs) and their associated health care expenditures for the dual eligible elders across long-term care (LTC) settings. We estimated the 12-month diagnosed prevalence of MHDs among dual eligible older adults in LTC and non-LTC settings and calculated the average incremental effect of MHDs on medical care, LTC, and prescription drug expenditures across LTC settings. METHODS Participants were fee-for-service dual eligible elderly beneficiaries from 7 states. We obtained their 2005 Medicare and Medicaid claims data and LTC program participation data from federal and state governments. We grouped beneficiaries into non-LTC, community LTC, and institutional LTC groups and identified enrollees with any of 5 MHDs (anxiety, bipolar, major depression, mild depression, and schizophrenia) using the International Classification of Diseases Ninth Revision codes associated with Medicare and Medicaid claims. We obtained medical care, LTC, and prescription drug expenditures from related claims. RESULTS Thirteen percent of all dual eligible elderly beneficiaries had at least 1 MHD diagnosis in 2005. Beneficiaries in non-LTC group had the lowest 12-month prevalence rates but highest percentage increase in health care expenditures associated with MHDs. Institutional LTC residents had the highest prevalence rates but lowest percentage increase in expenditures. LTC expenditures were less affected by MHDs than medical and prescription drug expenditures. IMPLICATIONS MHDs are prevalent among dual eligible older persons and are costly to the health care system. Policy makers need to focus on better MHD diagnosis among community-living elders and better understanding in treatment of MHDs in LTC settings.

PQRS Participation, Inappropriate Utilization of Health Care Services, and Medicare Expenditures

BACKGROUND Dual eligible Medicare and Medicaid beneficiaries consume disproportionate shares of both programs. OBJECTIVES To compare Medicare and Medicaid expenditures of elderly dual eligible beneficiaries with non-dual eligible beneficiaries based on their long-term care (LTC) use. RESEARCH DESIGN Secondary analysis of linked MAX and Medicare data in seven states. SUBJECTS Dual eligible adults (65+) receiving LTC in institutions, in the community, or not at all; and Medicare non-dual eligibles. MEASURES Medicaid acute medical and LTC expenditures per beneficiary year, Medicare expenditures. RESULTS Among dual eligibles and non-dual eligibles, the average number of diseases and case mix scores are higher for LTC users. Adjusting for case mix virtually eliminates the difference for medical costs, but not for LTC expenditures. Adjusting for LTC status reduces the difference in LTC costs, but increases the difference in medical costs. CONCLUSIONS Efforts to control costs for dual eligibles should target those in LTC while better coordinating medical and LTC expenditures.

Two Innovative Cancer Care Programs Have Potential to Reduce Utilization and Spending.

Visits to the emergency department (ED) are costly, and because some of them are potentially avoidable, some types of ED visits also may be indicative of poor care management, inadequate access to care, or poor choices on the part of beneficiaries. Billings and colleagues developed an algorithm to analyze ED visits and assign probabilities that each visit falls into several categories of appropriateness. The algorithm has been used previously to assess the appropriateness of ED visits at the community or facility level. In this analysis, the authors explain how the Billings algorithm works and how it can be applied to individual physician practices. The authors then present illustrative data from 2 years of Medicare claims data from 5 states. About one third of ED visits are deemed appropriate, and about half could have been treated in a primary care outpatient setting. Another 15% were deemed preventable or avoidable.

Inappropriate Utilization in Fee-for-Service Medicare and Medicare Advantage Plans:

Medicare’s Physician Quality Reporting System (PQRS) is the largest quality-reporting system in the U.S. health care system and a basis for the new value-based modifier system for physician payment. The PQRS allows health care providers to report measures of quality of care that include both the process of care and physiological outcomes. Using a multivariate difference-in-differences model, we examine the relationship of PQRS participation to three claims-computable measures of inappropriate utilization of health care services and risk-adjusted per capita Medicare expenditures. The data are a national random sample of PQRS-participating providers matched to nonparticipating providers by zip code and caseload. We found few significant relationships in the overall analysis. However, the magnitude and statistical significance of the desirable associations increased in subgroups of providers and beneficiaries more prone to overutilization (e.g., males, older beneficiaries, beneficiaries treated in larger medical practices or by nonphysicians, and practices in rural areas), and among beneficiaries with heart conditions, diabetes, and eye problems.

Innovative Models for High-Risk Patients Use Care Coordination and Palliative Supports to Reduce End-of-life Utilization and Spending

Background: Cancer patients often present to the emergency department (ED) and hospital for symptom management, but many of these visits are avoidable and costly. Objective: We assessed the impact of 2 Health Care Innovation Awards that used an oncology medical home model [Community Oncology Medical Home (COME HOME)] or patient navigation model [Patient Care Connect Program (PCCP)] on utilization and spending. Methods: Participants in COME HOME and PCCP models were matched to similar comparators using propensity scores. We analyzed utilization and spending outcomes using Medicare fee-for-service claims with unadjusted and adjusted difference-in-differences models. Results: In the adjusted models, both COME HOME and PCCP were associated with fewer ED visits than a comparison group (15 and 22 per 1000 patients/quarter, respectively; P<0.01). In addition, COME HOME had lower spending (

675 per patient/quarter; P<0.01), and PCCP had fewer hospitalizations (11 per 1000 patients/quarter; P<0.05), relative to the comparison group. Among patients undergoing chemotherapy, fewer COME HOME and PCCP patients had ED visits (18 and 28 per 1000 patients/quarter, respectively; P<0.01) and fewer PCCP patients had hospitalizations (13 per 1000 patients/quarter; P<0.05), than comparison patients. Conclusions: The oncology medical home and patient navigator programs both showed reductions in spending or utilization. Adoption of such programs holds promise for improving cancer care.
