Association of health professional shortage area hospital designation with surgical outcomes and expenditures among Medicare beneficiaries.
This study’s objective was to compare surgical outcomes and expenditures at hospitals located in Health Professional Shortage Areas to nonshortage area designated hospitals among Medicare beneficiaries. This cross-sectional retrospective study used data from 842,787 Medicare beneficiary patient admissions to hospitals with and without Health Professional Shortage Area designations for common operations including appendectomy, cholecystectomy, colectomy, and hernia repair from 2014 to 2018. Primary outcomes measures were 30-day mortality, hospital readmissions, and 30-day surgical episode payments. Patients (mean age=75.6 years, males=44.4%) undergoing common surgical procedures in shortage area hospitals were less likely to be White (84.6% vs 88.4%) and less likely to have≥2 Elixhauser comorbidities (75.5% vs 78.2%). Patients undergoing surgery at Health Professional Shortage Area hospitals had lower risk-adjusted rates of 30-day mortality (6.05% vs 6.69%) and readmission (14.99% vs 15.74%). Medicare expenditures at Health Professional Shortage Area hospitals were also lower than nonshortage designated hospitals ($28,517 vs $29,685).

The impact of Medicaid expansion on spending and utilization by older low-income Medicare beneficiaries.
This study examined indirect spillover effects of Affordable Care Act (ACA) Medicaid expansions to working-age adults on health care coverage, spending, and utilization by older low-income Medicare beneficiaries. The authors used data from the 2010-2018 Health and Retirement Study survey linked to annual Medicare beneficiary summary files. They estimated individual-level difference-in-differences models of total spending for inpatient, institutional outpatient, physician/professional provider services; inpatient stays, outpatient visits, physician visits; and Medicaid and Part A and B Medicare coverage. They also compared changes in outcomes before and after Medicaid expansion in expansion versus nonexpansion states. The sample included low-income respondents aged 69 and older with linked Medicare data, enrolled in full-year traditional Medicare, and living in the community. ACA Medicaid expansion was associated with a 9.8 percentage point increase in Medicaid coverage, a 4.4 percentage point increase in having any institutional outpatient spending, and a positive but statistically insignificant 2.4 percentage point change in Part B enrollment.

Incorporating added therapeutic benefit and domestic reference pricing into Medicare payment for expensive part B drugs.
The objective of this retrospective analysis was to identify expensive Part B drugs and to consider the evidence for each drug's added benefit in order to model a reimbursement policy for Medicare that integrates added benefit assessment and domestic reference pricing. Data were taken from a nationally representative sample of traditional Medicare Part B claims. The analysis showed that more than one-third of the expensive Part B drugs prescribed in 2019 offered low added benefit. The authors concluded that reference pricing based on added benefit assessment could be used to address the launch prices for expensive Part B drugs with low added benefit.

Opportunities for savings in risk arrangements for oncologic care.
High spending for cancer care is a target for savings as the United States hastens adoption of alternative payment through global payment models such as Accountable Care Organizations (ACOs) or Medicare Advantage (MA). The purpose of this study was to quantify the level at which Accountable Care Organizations ACOs and other risk-bearing organizations operating in a specific geographic area could realize savings by directing patients to efficient medical oncology practices. The incident cohort included 1,309,825 patients Options for directing differed across markets; the top quartile market had 10 or more oncology practices, but the bottom quartile had 3 or fewer oncology practices. Total spending (including Medicare Part D) in the incident cohort increased from a mean of $57,314 in 2009 to 2010 to $66,028 in 2016 to 2017. Within markets, total spending for practices in the highest spending quartile was 19% greater than in the lowest quartile. Hospital spending was the single largest component of spending in both time periods followed by Part B (infused) chemotherapy. Correlations in practice-level spending between the first-year (2009) and second-year (2010) spending were high.

Optimal care for kidney health: development of a Merit-based Incentive Payment System (MIPS) value pathway.
This article detailed the iterative consensus-building process used by the American Society of Nephrology Quality Committee to develop the Optimal Care for Kidney Health Merit-based Incentive Payment System (MIPS) Value Pathway (MVP). The Optimal Care for Kidney Health MVP, published in the 2023 Medicare Physician Fee Schedule Final Rule, included measures related to angiotensin-converting enzyme inhibitor and angiotensin receptor blocker use, hypertension control, readmissions, acute kidney injury requiring dialysis, and advance care planning. The MVP nephrology’s goal was to streamline measure selection in MIPS and served as a case study of collaborative policymaking between one professional organization and national regulatory agencies.

Use of intergovernmental transfers-based Medicaid supplemental payments to boost nursing home finances: evidence from Indiana nursing homes.
The objective of this study was to estimate the effect of participation in the intergovernmental transfers-based Medicaid supplemental payment program on nursing home revenue and expenditures. Data was taken from all Medicare and Medicaid-certified nursing homes in Indiana from 2009-17. The findings indicated that nursing homes owned or operated by nonstate governmental organizations received a fraction of the total supplemental payments on average, but the authors observed increased payments in later years. Participating nursing homes did not increase clinical expenses. The authors concluded that these findings raised questions regarding the transparency of financing arrangements between nonstate governmental organizations and nursing homes and the need to link supplemental payments to clinical expenses.

Who's accountable? Low-value care received by Medicare beneficiaries outside of their attributed health systems.
This study examined where and from whom Medicare beneficiaries aged 65 and older received forty low-value services during 2017-18 and identified factors associated with out-of-system receipt. The authors used national Medicare data for fee-for-service beneficiaries aged sixty-five and older and attributed to 595 US health systems for 2017 and 2018. Almost half (43%) of low-value services received by attributed beneficiaries originated from out-of-system clinicians: 38 percent from specialists, 4 percent from primary care physicians, and 1 percent from advanced practice clinicians. Recipients of low-value care were more likely to obtain care out of system if age 75 or older, male, non-Hispanic white, rural dwelling, more medically complex, or experiencing lower continuity of care. Out-of-system receipt was not associated with recipients' health systems' accountable care organization status.

Benchmarking changes and selective participation in the Medicare shared savings program.
In 2017 the Medicare Shared Savings Program (MSSP) began including regional spending into accountable care organization (ACO) benchmarks, demonstrating a preference for the participation of those ACOs and practices with lower baseline spending than their region. The purpose of this study was to isolate changes in spending due to changes in the mix of ACOs and practices participating in the MSSP as a method for characterizing providers' responses to these incentives. After 2017, the composition of the MSSP increasingly shifted to providers with lower preexisting levels of spending relative to their region, consistent with a selection response. Changes took place through the entry of new ACOs with lower baseline spending, the exit of higher-spending ACOs, and the reconfiguration of participant lists favoring lower-spending practices within continuing ACOs. The study found that although compositional changes could not be clearly tied to changes in benchmarking, the disproportionate participation of providers with lower baseline spending suggests sizable costs and the need for reforms in ACO benchmarking.

The role of financial incentives in biosimilar uptake in Medicare: Evidence from the 340b program.
This study’s goal was to investigate whether the 340B Drug Pricing Program, which offers eligible hospitals substantial discounts on drug purchases, inhibits biosimilar uptake. Almost one-third of eligible US hospitals participate in the program. The authors used regression discontinuity design and two high-volume biologics with biosimilar competitors, filgrastim and infliximab to estimate that 340B program eligibility was associated with a 22.9-percentage-point reduction in biosimilar adoption. Additionally, 340B program eligibility was associated with 13.3 more biologic administrations annually per hospital and $17,919 more biologic revenue per hospital. The effect was found to be that it inhibited biosimilar uptake, possibly because of financial incentives that make reference drugs more profitable than biosimilar medications.

Association of skilled nursing facility ownership by health care networks with utilization and spending.
The objective of this cross-sectional study was to determine the association of vertical integration of skilled nursing facilities (SNFs) within hospital networks with SNF utilization, readmissions, and spending. Claims data from Medicare beneficiaries aged 66 to 99 who had undergone elective hip replacement in nonfederal acute care hospitals during the study period was analyzed. Results showed that vertical SNF integration was associated with a higher rate of SNF utilization and a lower 30-day readmission rate; in spite of higher utilization, 30-day episode payments were slightly lower. Adjusted readmission rates were especially low for patients who were not sent to an SNF but were significantly higher for patients with a length of stay of less than 5 days. The authors concluded these findings support the value of integrating SNFs into hospital networks, but there is room for improvement in postoperative care early in the SNF patients’ stay.

How does the effect of the comprehensive Care for Joint Replacement model vary based on surgical volume and costs of care?
This article described differences in costs, quality, and patient selection between hospitals that continued to participate in the comprehensive Care for Joint Replacement (CJR) program after the CMS policy revision and those that withdrew from CJR before and after the implementation of CJR. Study subjects were Medicare beneficiaries who had undergone elective lower extremity joint replacement from 2013 to 2017. The results indicated that hospitals that continued to participate in CJR achieved a greater cost reduction. The authors noted that these the cost reductions were partly attributable to the avoidance of potential higher-cost patients.

Interhospital variability in health care-associated infections and payments after durable ventricular assist device implant among Medicare beneficiaries.
The purpose of this study was to examine differences in durable ventricular assist device implantation infection rates and associated costs across hospitals. The researchers utilized clinical data for 8,688 patients who received primary durable ventricular assist devices from the Society of Thoracic Surgeons Interagency Registry for Mechanically Assisted Circulatory Support (Intermacs) hospitals (n = 120) and merged that data with post-implantation 90-day Medicare claims. The primary outcome included infections within 90 days of implantation and Medicare payments. The study found that 27.8% of patients developed 3982 identified infections. The median adjusted incidence of infections (per 100 patient-months) across hospitals was 14.3 and differed according to hospital. Total Medicare payments from implantation to 90 days were 9.0% more in high versus low infection tercile hospitals. The researchers concluded that health-care-associated infection rates post durable ventricular assist device implantation varied according to hospital and were associated with increased 90-day Medicare expenditures.

Consequences of forgoing prescription drug subsidies among low-income Medicare beneficiaries with diabetes.
This study’s objective was to estimate the take-up of the Medicare Part D Low-Income Subsidy (LIS) among Medicare beneficiaries with diabetes and examine differences in out-of-pocket costs and prescription drug use between LIS enrollees and LIS-eligible non-enrollees. Data from the Health and Retirement Study linked to Medicare administrative data from 2008 to 2016 was used. The authors first estimated LIS take-up stratified by income (≤100% of the Federal Poverty Level [FPL] and >100% to ≤150% of FPL). Second, to assess the consequences of forgoing the LIS among near-poor beneficiaries (incomes >100% to ≤150% of FPL), they conducted propensity score-weighted regression analyses to compare out-of-pocket costs, prescription drug use, and cost-related medication non-adherence among LIS enrollees and LIS-eligible non-enrollees. Among Medicare beneficiaries with diabetes, 68.1% of those considered near-poor (incomes >100% to ≤150% of FPL) received the LIS, compared to 90.3% of those with incomes ≤100% of FPL. Among near-poor beneficiaries, LIS-eligible non-enrollees incurred higher annual out-of-pocket drug spending ($518], filled 7.3 fewer prescriptions for diabetes, hypertension, and hyperlipidemia drugs, and were 8.9 percentage points more likely to report skipping drugs due to cost. all compared to LIS enrollees.

Association between care fragmentation and total spending after durable left ventricular device implant: a mediation analysis of health care-associated infections within a national Medicare-Society of Thoracic Surgeons INTERMACS linked dataset.
The purpose of this study was to examine the relationship between care fragmentation and total spending for durable left ventricular assisted device (LVAD) implant, and whether this relationship is mediated by infections. The researchers developed a measure of care fragmentation based on the number of shared medical professionals providing care to 4,987 Medicare beneficiaries undergoing LVAD implantation. The study found that the indirect effect of care fragmentation, through infections, was positive and statistically significant. The researchers concluded that higher care fragmentation associated with durable LVAD implantation is related with a greater incidence of infections and higher Medicare beneficiary payments.

Estimated wasteful spending on aducanumab dispensing in the U.S. Medicare population: a cross-sectional analysis.
The purpose of this study was to quantify the amount of aducanumab that is discarded because of vial dose size and calculate the potential Medicare savings that could be created by changing the vial size and drug weight to make dispensing more efficient and reduce the amount of discarded drug. The researchers calculated estimates for the monthly amount of discarded drug for each study participant, and then annualized the estimates. Costs were calculated using the 300 mg vial price, which is the larger of the two vial sizes currently available, and calculations were then made for simulated vials in three combinations (100 and 170 mg; 170 and 250mg; and 80mg, 170, and 300 mg.) Costs for each combination were then calculated. The study found that assuming a 10% drug uptake, the equivalent of between 132,398 and 694,258 vials of aducanumab would be discarded costing Medicare between $115.4 million and $604.9
million each year. If the 300 mg/3.0 ml vial was reduced to 100 mg/1.0 ml, Medicare savings would range between $70.9 and $369.0 million per year. The researchers concluded that reducing aducanumab vial size could decrease wasteful spending from discarded vials by over 60%.

Prescribing of low- versus high-cost Part B drugs in Medicare Advantage and traditional Medicare.
The purpose of this study was to compare Medicare Advantage (MA) coverage with traditional Medicare (TM) coverage as it relates to whether MA is associated with greater efficiency of prescribing Part B drugs. The authors sampled 20% of all 2016 outpatient and carrier TM claims and MA encounter records and Master Beneficiary Summary File data and analyzed whether MA enrollees more often received the low-cost Part B drug compared to TM enrollees. Four clinical scenarios were evaluated where multiple, similarly effective drugs exist: (1) anti-VEGF agents to treat macular degeneration, (2) bone resorption inhibitors for osteoporosis, (3) bone resorption inhibitors for malignant neoplasms, and (4) intravenous iron for iron deficiency anemia. The researchers estimated spending differences if TM prescribing aligned with MA prescribing and evaluated whether differences between MA and TM prescribing patterns were due to differences in the hospitals and provider practices who treat MA and TM enrollees or differences in how those hospitals and provider practices engage with their MA vs TM patients. The researchers found that more MA enrollees received the low-cost drug vs. TM enrollees in all 4 clinical scenarios, and that if TM prescribing matched that of ME prescribing, there would be a spending savings of 6% to 20% for each of the 4 scenarios. The study concluded that in 4 clinical scenarios in which similarly or equally effective treatment options exist, MA enrollees were more likely than TM enrollees to receive low-cost Part B drugs.

Increased complications and cost associated with hip arthroplasty for femoral neck fracture: evaluation of 576,119 Medicare patients treated with hip arthroplasty.
The authors compared perioperative complications and costs of total hip arthroplasty (THA) for treatment of osteoarthritis (OA) to hemiarthroplasty (HA) and THA for treatment of femoral neck fractures (FNFs). Data from CMS were used to identify all patients 65 or older undergoing primary hip arthroplasty. The results showed that CMS hip arthroplasty patients with an FNF had significantly higher rates of mortality, thromboembolic events, readmission, and greater direct cost. The authors concluded that reimbursement models for arthroplasty should account for different perioperative complication and resource utilization for FNF patients.

Eating disorders in the U.S. Medicare population.
This cross-sectional study explored the prevalence, sociodemographic and clinical characteristics, and health care spending for Medicare enrollees with eating disorders. A representative 20% sample of 2016 Medicare inpatient, outpatient, carrier, and home health fee-for-service claims and Medicare Advantage encounter records was used. The sample included almost 12 million Medicare enrollees of whom 0.15% had an eating disorder diagnosis. A greater proportion of individuals diagnosed with an eating disorder diagnosis were female, under age 65, and dually eligible for Medicaid due to disability or low-income qualification than those without a diagnosis. Individuals with eating disorders had higher rates of comorbid conditions, with the greatest differences in cardiac arrythmias, arthritis, and thyroid conditions. Spending was $29,456 for enrollees with eating disorders compared to $7,418 without.

Physician practices with robust capabilities spend less on Medicare beneficiaries than more limited practices.
Researchers used data from the 2017 National Survey of Healthcare Organizations and Systems to examine the association of practice-level capabilities with process measures of quality, utilization, and spending. They found that quality and utilization did not differ by practice-level capabilities. Physician practice locations with robust capabilities spent less on Medicare fee-for-service beneficiaries but delivered quality of care comparable to the quality delivered in locations with low or mixed capabilities.

ACO awareness and perceptions among specialists versus primary care physicians: a survey of a large Medicare Shared Savings program.
This research letter describes a survey that was conducted to compare accountable care organization (ACO) awareness and perceptions among specialists versus primary care physicians (PCPs). The survey was administered in 2018 to clinicians in the Physician Organization of Michigan ACO, which was the largest Medicare Shared Savings Program (MSSP) in Michigan and among the ten largest nationally at the time. The analysis focused on 1022 non-pediatrician physician respondents practicing within 10 provider organizations. Physician respondents included PCPs (23%) and specialists (77%). The most common specialty was internal medicine (20%), followed by surgeons (14%). Specialists were less likely to be aware of ACO participation and incentives. They were also 25% less likely to know they were in an ACO compared to PCPs. In addition, specialists were 18% less likely to know their ACO was accountable for both spending and quality or that their ACO had lowered spending in the previous year. This difference in perception may help to explain ACOs’ modest impact on spending and quality.

Geographic variation in Medicare fee-for-service health care expenditures before and after the passage of the Affordable Care Act.
This cross-section study examined geographic variation in Medicare fee-for-service health care expenditures before and after the passage of the Affordable Care Act. The study included all fee-for-service Medicare enrollees aged 65 and older from 2007 to 2018 using data from the Medicare Geographic Variation Public Use File. Hospital referral regions (HRRs) were grouped in each year into deciles (10 equal groups) based on per-beneficiary total spending. Geographic variation was stable from 2007 to 2011 and declined steadily from 2012 through 2018. In specific spending categories, only home health had statistically significant reductions in geographic variation. The ratio of home health spending among HRRs in the top to bottom deciles of total Medicare spending fell from 5.14 in 2007 to 3.45 in 2018.

Trends in anticoagulation prescription spending among Medicare Part D and Medicaid beneficiaries between 2014 and 2019.
Researchers examined contemporary direct oral anticoagulant (DOAC) spending patterns within Medicare Part D and Medicaid between 2014 and 2019. They found that, although overall DOAC spending is increasing, DOAC use may be associated with lower downstream medical expenditures compared with warfarin stemming from decreased risk of major bleeding and stroke and reduced drug monitoring.

Wide variation in surgical spending within hospital systems: a missed opportunity for bundled payment success.
Researchers sought to measure the extent of variation in episode spending around total hip replacement for fee-for-service Medicare patients within and across hospital systems identified in the American Hospital Association Annual Survey. They found that average episode payments varied nearly as much within hospital systems as they did between the lowest- and highest-cost quintiles of systems, with variation driven by post-acute care utilization.

Predicting losses from Medicare Shared Savings Program departures.
Researchers conducted an observational study to understand how accountable care organization (ACO) exit could affect Shared Savings Program (SSP) financial performance. They found that nearly 80% of ACOs were still active at the end of 2016. Among the subset that faced contract renewal in 2019, 40% were known to have exited the SSP. By 2022, ACOs that exited in 2019 could cost the SSP $186.9 million in lost savings. If the exit rate observed in 2019 continues, the SSP could suffer $396.8 million in lost savings by 2022.
