Community health center staff perspectives on financial payments for social care.
The purpose of this study was to examine how community health center (CHC) staff perceive the current and potential influence of fee-for-service payments on clinical teams' engagement in these activities. The researchers interviewed 42 clinicians, frontline staff, and administrative leaders employed by12 Oregon CHC clinical sites about their social care initiatives. The study grouped the findings into three categories: 1. participants' awareness of existing or anticipated financial incentives, 2. uses for incentive dollars, and 3. perceived impact of financial incentives on social care activities in clinical practices. Current or anticipated important uses for incentive dollars included paying for social care staff, providing social services, and supporting additional fundraising efforts. Frontline staff reported that the strongest influence on clinic social care practices was the ability to provide responsive social services. Clinic leaders reported that for financial incentives to significantly change CHC practices would necessitate payments large enough to expand the social care workforce as well.

High deductibles are associated with severe disease, catastrophic out-of-pocket payments for emergency surgical conditions.
This retrospective analysis of claims data examined the association of a high-deductible health insurance plan (HDHP) with severe disease and catastrophic out-of-pocket payments for emergency surgical conditions (e.g., appendicitis, cholecystitis, diverticulitis, and intestinal obstruction). Primary outcome was disease severity at presentation-determined using ICD-10-CM diagnoses codes and based on validated measures of anatomic severity (e.g., perforation, abscess, diffuse peritonitis). The secondary outcome was catastrophic out-of-pocket spending, defined by the World Health Organization as out-of-pocket spending >10% of annual income. Among 43,516 patients [mean age 48.4 years; 51% female], 41% were enrolled in HDHPs. Despite being younger, healthier, wealthier, and more educated, HDHP enrollees were more likely to present with more severe disease (28.5% vs 21.3%); even after adjusting for relevant demographics. HDHP enrollees were also more likely to incur 30-day out-of-pocket spending that exceeded 10% of annual income (20.8% vs 6.4%).

Comparison of primary payer in cancer registry and discharge data.
The purpose of this cross-sectional study was to ascertain agreement between variables capturing the primary payer at cancer diagnosis across the Pennsylvania Cancer Registry (PCR) and statewide facility discharge records (Pennsylvania Health Care Cost Containment Council [PHC4]) for adults under 65 years, and to examine variables related with misclassification of Medicaid status in the registry given the role of managed care. The researchers evaluated agreement of payer at diagnosis across data sources. The study found that agreement of payers was high for private insurance, but there was misclassification and/or underreporting of Medicaid in the registry. Among cases with "other" and "unknown" insurance, 73.8% and 62.1%, respectively, had private insurance. Medicaid managed care was related with a statistically significant increase of 12.6 percentage points in the probability of misclassifying Medicaid enrollment as private insurance in the registry.

Effectiveness of a bundled payments for care improvement program for chronic obstructive pulmonary disease.
This single-site retrospective observational study evaluated the impact of an evidence-based transitions of care program on episode costs and readmission rates, comparing patients hospitalized for COPD exacerbations who received versus those who did not receive the intervention. Between October 2015 and September 2018, 132 received and 161 did not receive the program. Below target mean episode costs were found for six out of eleven quarters for the intervention group, as opposed to only one out of twelve quarters for the control group. Overall, there were non-significant mean savings of $2551 in episode costs relative to target costs for the intervention group, though results varied by index admission diagnosis-related group (DRG). There were additional costs of $4184 per episode for the least-complicated cohort (DRG 192), but savings of $1897 and $1753 for the most complicated index admissions (DRGs 191 and 190, respectively). A significant mean decrease of 0.24 readmissions per episode for intervention was observed in 90-day readmission rates relative to control. Skilled nursing facility readmissions and hospital discharges were factors of higher costs (mean increases of $9098 and $17,095 per episode respectively).

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.

Medicaid value-based payments and health care use for patients with mental illness.
This retrospective cohort study’s objective was to investigate if New York State's Medicaid value-based payment reform was associated with improved utilization patterns for patients with mental illness (major depression disorder, bipolar disorder, and/or schizophrenia). The cohort included Medicaid 306,290 individuals with depression (67.4% female; mean age, 38.6 years), 85,105 patients with bipolar disorder (59.6% female; mean age, 38.0 years), and 71,299 patients with schizophrenia (45.1% female mean age, 40.3 years). After adjustment, the analysis estimated a statistically significant, positive association between value-based payments and behavioral health visits for patients with depression (0.91 visits) and bipolar disorder (1.01 visits). There were no statistically significant changes to primary care visits for patients with depression and bipolar disorder, but value-based payments were associated with reductions in primary care visits for patients with schizophrenia (-1.31 visits). In every diagnostic population, value-based payment was associated with significant reductions in mental health emergency department visits (population with depression: -0.01 visits; population with bipolar disorder: -0.02 visits; population with schizophrenia: -0.04 visits).

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.

Impact of higher payments for rural home health episodes on rehospitalizations.
This article evaluated the impact of higher Medicare payments for rural home health care on rehospitalizations. In 2010, Medicare began paying home health (HH) providers 3% more to serve rural beneficiaries. The authors used Medicare data on postacute HH episodes from 2007 to 2014 to estimate the impact of higher payments on beneficiaries outcomes using difference-in-differences analysis, comparing rehospitalizations between rural and urban postacute HH episodes before and after 2010. Their sample included 5.6 million post acute HH episodes (18% rural). After 2010 30- and 60-day rehospitalization rates declined by 10.08% and 16.49% for urban HH episodes and 9.87% and 16.08% for rural HH episodes, respectively. The difference-in-difference estimate was 0.29 percentage points and 0.57 percentage points for 30- and 60-day rehospitalization, respectively.

Medicaid reimbursement rates for primary care services and behavioral health outcomes.
This AHRQ-authored research studied the effects of changing Medicaid reimbursement rates for primary care services on behavioral health outcomes-defined here as mental illness and substance use disorders. The authors applied two-way fixed-effects regressions to survey data specifically designed to measure behavioral health outcomes over the period 2010-2016. They found that higher primary care reimbursement rates reduce mental illness and substance use disorders among non-elderly adult Medicaid enrollees, although they interpreted findings for substance use disorders with some caution as they may be vulnerable to differential pre-trends. Overall, their findings suggest positive spillovers from a policy designed to target primary care services to behavioral health outcomes.

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.

State-level variation in supplemental maternity kick payments in Medicaid managed care.
The purpose of the cross-sectional study described in this research letter was to assesses the prevalence and magnitude of state-level delivery event–triggered kick payments to Medicaid managed care (MMC) plans for covering pregnant patients and the association of such payments with delivery costs. MMC kick payment rates were compared with average state Medicaid fee-for-service (FFS) payments for delivery hospitalizations and state kick payment rates compared with the Medicaid-Medicare fee index. The authors found “substantial and potentially unwarranted” state variation in delivery kick payment rates within MMC. They noted that if kick payment rates are set too low, plans may attempt to avoid pregnant enrollees by limiting coverage of certain services or restricting maternity care clinicians in their networks, with consequences for Black and Indigenous maternity patients.

Implications of DRG classification in a bundled payment initiative for COPD.
The researchers hypothesized that patients included in a the Medicare Bundled Payments for Care Improvement (BPCI) initiative for chronic obstructive pulmonary disease (COPD) would have less severe illness and decreased hospital utilization compared with those excluded from the bundled payment initiative. They concluded that the use of DRGs to identify patients with COPD for inclusion in the BPCI initiative led to the exclusion of more than one-third of patients with acute exacerbations.

Public and private payments for physician office visits.
Using data for 2014-15 from the Medical Expenditure Panel Survey to estimate standardized payments for nonelderly adults' physician office visits by type of insurance, researchers found that adults with public insurance, especially Medicaid, had substantially lower provider payments, out-of-pocket spending, and third-party payments than their peers with employer-sponsored or Marketplace insurance.

The alternative quality contract: impact on service use and spending for children with ADHD.
The authors used Blue Cross-Blue Shield of Massachusetts (BCBSMA) claims for 2006-2011 to compare youths enrolled in provider organizations participating in the alternative quality contract (AQC) with those not participating. They found that the AQC was associated with small increases in the probability of any outpatient visits and in the probability and number of medication management visits among children with attention-deficit hyperactivity disorder (ADHD). Further, spending did not change, and there was no evidence of reductions in service utilization or spending for children with ADHD in the first three years of AQC implementation.

The moral hazard effects of consumer responses to targeted cost-sharing.
This paper examines the effects of the reference pricing program implemented by the California Public Employees Retirement System (CalPERS) in 2012. The investigators found that the cost savings from the reference pricing program was about two to three times as large as the reduction from implementing a high-deductible health plan, while the accompanying consumer surplus reduction was much smaller under reference pricing.

What role does efficiency play in understanding the relationship between cost and quality in physician organizations?
Previous studies demonstrate overuse of a narrow set of services, suggesting provider inefficiency, but existing studies neither quantify inefficiency more broadly nor assess its variation across physician organizations (POs). This study found that POs had substantial variation in efficiency, producing widely differing levels of quality for the same cost.

Reporting from the front lines: implementing Oregon's alternative payment methodology in federally qualified health centers.
Alternative payment models have been proposed as a way to facilitate patient-centered medical home model implementation, yet little is known about how payment reform translates into changes in care delivery. This study conducted site visits, observed operations, and conducted interviews within 3 Federally Qualified Health Center organizations. They identified several care delivery changes during the early stages of implementation, as well as challenges associated with this new model of payment.

Early lessons on bundled payment at an academic medical center.
This study was a difference-in-differences study of Medicare fee-for-service patients hospitalized from April 2011 to June 2012 and October 2013 to December 2014 for lower extremity joint arthroplasty, cardiac valve procedures, or spine surgery. It examined total episode costs and costs by service category. It concluded that opportunities for savings under bundled payment may be greater for lower extremity joint arthroplasty than for other conditions.

Misclassification risk of tier-based physician quality performance systems.
The authors estimated misclassification rates for two-category high-quality physician identification systems. They found that current methods for profiling physicians on quality may produce misleading results, and that misclassification is a policy-relevant measure of the potential impact of tiering on providers, payers, and patients. They concluded that quantifying misclassification rates should inform the construction of high-performance networks and quality improvement initiatives.

Defining hip fracture with claims data: outpatient and provider claims matter.
Medicare claims are commonly used to identify hip fractures, but there is no universally accepted definition. The authors of this study found that a definition using inpatient claims identified fewer fractures than a definition including outpatient and provider claims. Few additional fractures were identified by including inconsistent diagnostic and procedural codes at contiguous sites. The authors recommend that future studies publish their definition of fracture and specify if diagnostic codes from contiguous fracture sites were used.

Price variations and their trends in U.S. hospitals.
This study tracked trends in prices paid to hospitals by commercial insurers over the period 2008 to 2014 using private sector claims data that contain actual payments. It contrasted these with trends in the CMS published charges. Results indicated that variation in actual commercially-transacted prices is substantially lower than variation in published charges.
