Luck of the draw: role of chance in the assignment of Medicare readmissions penalties.
Pay-for-performance programs are one strategy used by health plans to improve the efficiency and quality of care delivered to beneficiaries. Under such programs, providers are often compared against their peers in order to win bonuses or face penalties in payment. The purpose of this study was to investigate the impact luck can have on the assessment of performance, the researchers investigated its role in assigning penalties under Medicare's Hospital Readmissions Reduction Policy (HRRP), a program that penalizes hospitals with excess readmissions.

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.

The effect of hospital safety net status on the association between bundled payment participation and changes in medical episode outcomes.
This study evaluated whether hospital safety net status affected the association between bundled payment participation and medical outcomes. The hospitals included were participants in Medicare’s Bundled Payments for Care Improvement (BCPI) program from 2011-2016. Data from Medicare fee-for-service beneficiaries hospitalized for acute myocardial infarction, pneumonia, congestive heart failure, and chronic obstructive pulmonary disease were used. Among BCPI hospitals, safety net status was not associated with differential postdischarge spending or quality. However, BPCI safety net hospitals had differentially greater discharge due to institutional post-acute care and lower discharge home with home health than BPCI non-safety net hospitals.

Changes in hospital-acquired conditions and mortality associated with the hospital-acquired condition reduction program.
This study evaluated changes in Hospital-Acquired Conditions (HACs) and 30-day mortality after the announcement of the Centers for Medicare and Medicare Services’ Hospital-Acquired Condition Reduction Program (HACRP) in August 2013. The authors evaluated models to test for changes in HACs and 30-day mortality before and after the Affordable Care Act (ACA), and after the HACRP. Fee-for-service Medicare claims from 2009 to 2015 were used. The HAC rate declined after the ACA was passed and declined further after the HACRP announcement. However, 30-day mortality rates were unchanged.

Changes in patient experiences and assessment of gaming among large clinician practices in precursors of the merit-based incentive payment system.
Medicare's Merit-Based Incentive Payment System (MIPS), a public reporting and pay-for-performance program, adjusts clinician payments based on publicly reported measures that are chosen primarily by clinicians or their practices. Within precursor programs of the MIPS, this study examined 1) practices' selection of Consumer Assessment of Healthcare Providers and Systems (CAHPS) patient experience measures for quality scoring under pay-for-performance and 2) the association between mandated public reporting on CAHPS measures and performance on those measures.

Medicare Advantage plan double bonuses drive racial disparity in payments, yield no quality or enrollment improvements.
Using national data for 2008-18, investigators found that double bonuses were not associated with either improvements in plan quality or increased Medicare Advantage enrollment. Additionally, double bonuses increased payments to plans to care for Black beneficiaries by $60 per year, compared with $91 for White beneficiaries. These findings suggest that double bonuses not only fail to improve quality and enrollment but also foster a racially inequitable distribution of Medicare funds that disfavors Black beneficiaries. This study supports eliminating double bonuses, thereby saving Medicare an estimated $1.8 billion per year.

Alzheimer's disease and related dementias and episode spending under Medicare's Bundled Payment for Care Improvements Advanced (BPCI-A).
Investigators evaluated the prevalence of Alzheimer’s disease and related dementias (ADRD) across the episodes included in Medicare's Bundled Payments for Care Improvement Advanced (BPCI-A) program and the association between ADRD and 90-day spending among hospitals participating in the BPCI-A program. They found that ADRD is associated with higher episode spending, highlighting the importance of closely monitoring the experience of these patients under BPCI-A to ensure that they are receiving appropriate care. This is particularly important for episodes like sepsis and pneumonia that are common among patients with ADRD and also highly prevalent under BPCI-A.

The CMS State Innovation Models Initiative and improved health information technology and care management capabilities of physician practices.
The Centers for Medicare and Medicaid Services' (CMS) State Innovation Models (SIMs) initiative funded 17 states to implement health care payment and delivery system reforms to improve health system performance. The authors investigated whether SIM improved health information technology (HIT) and care management capabilities of physician practices. They found that the CMS SIM Initiative did not accelerate the adoption of ten foundational physician practice capabilities beyond national trends.

Payment discrepancies and access to primary care physicians for dual-eligible Medicare-Medicaid beneficiaries.
This study examined whether the Affordable Care Act (ACA) primary care fee bump for dual-eligible Medicare-Medicaid beneficiaries impacted primary care physicians (PCP) acceptance of duals. The authors assessed differences in the likelihood that PCPs had dual caseloads of ≥10% or 20% in states with lower versus full dual reimbursement using linear probability models adjusted for physician and area-level traits. The proportion of PCPs with dual caseloads of ≥10% or 20% decreased significantly between 2012 and 2017. The fee bump was not consistently associated with increases in dual caseloads.

Identifying outlier patterns of inconsistent ambulance billing in Medicare.
The objective of this study was to illustrate a method that accounts for sampling variation in identifying suppliers and counties with outlying rates of a particular pattern of inconsistent billing for ambulance services to Medicare. The investigators concluded that health care fraud and abuse were frequently asserted but could be difficult to detect. They suggested that their data-driven approach may be a useful starting point for further investigation.

Preparing for bundled payments: impact of complications post-coronary artery bypass grafting on costs.
This study examined the impact of complications on bundled payments for coronary artery bypass grafting (CABG) for care provided from admission through 90 days post-discharge. The authors linked clinical and internal cost data for patients undergoing CABG from 2014 to 2017 at a single institution. They performed multivariable linear regression to evaluate drivers of high costs, adjusting for preoperative and intraoperative characteristics and postoperative complications. They reviewed records of 1789 patients undergoing CABG with an average of 2.7 vessels. A large proportion of patients were diabetic and obese. Factors associated with increased adjusted costs were preoperative renal failure, diabetes and body mass index, postoperative stroke, prolonged ventilation, rebleeding requiring reoperation, and renal failure with varying magnitude.

The impact of capitated payment on preventive care utilization in community health clinics.
Only half of the United States population regularly receives recommended preventive care services. Alternative payment models (e.g., a per-member-per-month capitated payment model) may encourage the delivery of preventive services when compared to a fee-for-service visit based model; however, evaluation is lacking in the United States. This study assessed the impact of implementing Oregon's Alternative Payment Methodology (APM) on orders for preventive services within community health centers (CHCs).

Are state telemedicine parity laws associated with greater use of telemedicine in the emergency department?
Telemedicine is a valuable tool to improve access to specialty care in emergency departments (EDs), and states have passed telemedicine parity laws requiring insurers to reimburse for telemedicine visits. The objective of this study was to determine if there was an association between such laws and the use of telemedicine in an ED. The investigators concluded that telemedicine parity laws were not associated with use of telemedicine in the ED.

Avoiding Medicaid: characteristics of primary care practices with no Medicaid revenue.
Primary care access for Medicaid patients is an ongoing area of concern. Most studies of providers' participation in Medicaid have focused on factors associated with the Medicaid program, such as reimbursement rates. Few studies have examined the characteristics of primary care practices associated with Medicaid participation. In this study, the investigators used a nationally representative survey of primary care practices to compare practices with no, low, and high Medicaid revenue.

Documenting new ways of delivering care under Oregon's Alternative Payment and Advanced Care Model.
This study’s objective was to describe trends in rates of traditional face-to-face office visits and “Care Services That Engage Patients” (Care STEPs) documentation among community health centers (CHCs) involved in the first 3 phases Oregon’s Alternative Payment and Advanced Care Model (APCM) pilot program. In this program, participating community health centers (CHCs) received per-member-per-month payments for empaneled Medicaid patients in lieu of standard fee-for-service Medicaid payments. Among participating CHCs, the mean rate of face-to-face visits with billable providers declined. Care STEPS documentation increased, but the difference was not statistically significant. The Care STEPs category New Visit Types were documented most frequently. There were significant increases in document of Patient Care Coordination and Integration, and a smaller but still significant increase in Reducing Barriers to Health. There was a significant decrease in documentation done by physicians and advanced practice providers with an increase by ancillary staff.

Opportunities for surgical leadership in managing population health costs.
The concept of population health management—long a mainstay in primary care and chronic disease management—is taking root in surgery. The 2010 Affordable Care Act (ACA) ushered in the implementation of several innovative payment models that shift accountability for population costs to health systems and providers. The authors discuss the implications of th trends for the surgical profession.

ACOs holding commercial contracts are larger and more efficient than noncommercial ACOs.
The researchers examined differences between commercial accountable care organizations (ACOs) and noncommercial ACOs. They found that among all ACOs, there was low uptake of quality and efficiency activities; commercial ACOs reported more use of disease monitoring tools, patient satisfaction data, and quality improvement methods; and about two-thirds of the ACOs had established processes for distributing any savings accrued. They concluded that ACO delivery systems remain at a nascent stage.

ICD-9 code-based venous thromboembolism performance targets fail to measure up.
Suboptimal prevention practices have prompted payers to consider hospital-associated Venous thromboembolism (VTE) as a potentially preventable condition for which financial incentives or penalties exist to drive practice improvement. The authors reviewed a subset of hospital-associated VTE that were identified by ICD-9 codes used by a state-run pay-for-performance quality improvement program and discuss their findings.

Medicare's new bundled payment for joint replacement may penalize hospitals that treat medically complex patients.
Using Medicare claims for patients in Michigan who underwent lower extremity joint replacement in the period 2011-13, the researchers applied payment methods analogous to those CMS intends to use in determining annual bonuses or penalties (reconciliation payments) to hospitals. Their findings suggest that CMS should include risk adjustment in the Comprehensive Care for Joint Replacement program and in future bundled payment programs.

Pay for performance in Medicaid: evidence from three natural experiments.
This study examined the impact of pay for performance in Medicaid on the quality and utilization of care. Primary outcomes of interest were Healthcare Effectiveness Data and Information Set (HEDIS)-like process measures of quality, utilization by service category, and ambulatory care-sensitive admissions and emergency department visits. Its findings were mixed, with no measurable quality improvements across the three states (Pennsylvania, Minnesota, Alabama), but reductions in hospital admissions in two programs.

Association between Medicare accountable care organization implementation and spending among clinically vulnerable beneficiaries.
The purpose of this cohort study was to examine the effect of Medicare accountable care organization (ACO) contracts on both spending and high-cost institutional utilization for all Medicare beneficiaries and for clinically vulnerable beneficiaries. The main outcomes and measures for this study were total spending per beneficiary-quarter, spending categories, utilization of hospitals and emergency departments, ambulatory care sensitive admissions, and 30-day readmissions. The study found that total spending decreased by $34 per beneficiary-quarter after implementation of ACO contracts across the overall Medicare population and decreased $114 in clinically vulnerable patients. In the overall Medicare cohort, hospitalizations and emergency department visits decreased by 1.3 and 3.0 events per 1000 beneficiaries per quarter, respectively. Hospitalizations and emergency department visits decreased in the clinically vulnerable cohort by 2.9 and 4.1 events per 1000 beneficiaries per quarter, respectively. Variations in total spending related with ACOs did not differ by clinical condition of beneficiaries.

Reference pricing with endogenous or exogenous payment limits: impacts on insurer and consumer spending.
The authors extended reference pricing (RP) models to a hospital context focusing on insurer and consumer payments. They found that, for 2 years following RP implementation, insurer payments to high-price and low-price hospitals moved downward, consistent with endogenous RP. When the reference price was not reset to account for changes in market prices, insurer payments to low-price hospitals reverted to pre-implementation levels, consistent with exogenous RP.
