Value-Based Evidence


Helping healthcare organizations see CSI products in a value-based healthcare model

Hospitals, practices and physicians face significant challenges as our healthcare system transitions from fee-for-service to value-based models. Administrators often face shifting priorities and must train staff to address a value-based care model that rewards outcomes and prevention.

The transformation is ongoing:

  • The Centers for Medicare and Medicaid (CMS) committed to disburse 50% of total payments through value-based payments by 201841
  • The Health Care Transformation Task Force, a group of some of the largest US health systems and insurers, committed to shifting 75% of its members’ business into contracts with incentives for health outcomes, quality and cost management42

Economic Evidence

Analysis of cost-effectiveness of treatment with orbital atherectomy

The Power of Data

As your hospital staff weighs crucial product and technology decisions, your purchasing decision makers need all the available information possible. CSI offers an economic model tool for our coronary device to help hospitals and physicians calculate the economic impact of our technology and programs.

Improving PAD Patient Outcomes and Reducing Costs

The Diamondback 360® Peripheral Orbital Atherectomy System, in combination with percutaneous angioplasty (PTA), have been shown to offer more favorable short-term and long-term patient outcomes in PAD treatment when compared head-to-head with balloon angioplasty alone:5

  • Lower percentage of patients requiring revascularization 6 – 12 months after the procedure5,6
  • Lower rate of dissections5,6
  • Reduced need for adjunctive/bail-out stenting5,6
  • Higher percentage of patients achieving ≤30% final residual stenosis5

An incremental cost analysis of OAS in the treatment of PAD11:

  • 1-year incremental cost of $549 compared to balloon angioplasty (BA)
  • Incremental cost-effectiveness ratio (ICER) of $3,441
  • ICER result well below the $50,000 threshold generally considered cost effective in the US
  • Cost to treat restenosis: $13,734 for OAS + BA vs. $20,609 for BA alone
  • Costs for a reintervention procedure is higher in the BA group by $7,000

Clinical outcomes from COMPLIANCE 360°, a prospective, multicenter, randomized study comparing OAS+BA vs BA alone for treatment of calcified femoropopliteal lesions. Site of service, hospital charges, and associated medical resource utilization were obtained from Uniform Billing statements for index treatments and associated revascularizations out to 1 year. Hospital costs were estimated using hospital-specific, procedure-specific cost-to-charge ratios. Length of stay and procedural data were collected from participating study sites. OAS+BA n=25 and lesions=38; BA alone n=25 and lesions=27.11

Improving CAD Patient Outcomes and Reducing Costs

The annual burden of illness due to coronary artery disease is estimated at between $1 billion and $3 billion.18 Patients with severe calcification present a greater risk of complication rates, which increases hospitalization costs.4,19

Diamondback 360® Coronary Orbital Atherectomy System (OAS) reduces severe calcium, enabling successful stent delivery to help optimize stent expansion and PCI outcomes.

The coronary OAS is the first novel technology to receive FDA approval to specifically treat severely calcified lesions.4 The Diamondback 360® Coronary OAS has a unique mechanism of action designed to:

  • Treat 360˚of the vessel
  • Provide continuous flow of blood and saline during orbit, minimizing thermal injury

An Incremental Cost Analysis of OAS in the Treatment of CAD Found:

  • Savings could be as high as $1,118 (compared to the PCI standard of care minus the cost of the device)7
  • Average patient gaining 0.247 life-years7
  • $11,895 per life-year gained as a calculated ICER7
Results calculated based on modeled synthesis of clinical and economic data utilizing the cost of using the OAS technology in elderly (>65 years) Medicare patients with de novo severely calcified lesions compared to cost offsets. Clinical data from the ORBIT II trial using the pooled analysis of the HORIZONS-AMI and ACUITY trials for comparison. Index procedure costs from Medicare data.
