Bundled Payments

P4P payment systems continue to evolve as implementation widens. The most widely publicized next generation of P4P is the Prometheus Payment model. Prometheus reimburses based on evidence-based case rates (ECRs) that include a lump sum for total cost of care based on the evidence recommended care (38). Each ECR has a built in report card, which allows for P4P to be taken into account. Other programs include Geisinger (Pennsylvania, 112) and Carol Complete (Minnesota). Rosenthal (218) provides a broad overview of these emerging payment systems. More programs that use ECRs are sure to surface in the near future. The primary drawback (321) to bundled payments thus far has been a limited sample size, and incomplete data to properly determine "evidence-based" payment rates.

  • Report outlines new performance based reimbursement model called Prometheus Payment.
  • Prometheus reimburses on the basis of negotiated evidence-based case rates (ECRs) supplemented by bonus payments for quality and efficiency.
  • For Prometheus “to work well, patients would need a medical home and rely on that provider to take them through the system.”

Significance to Literature:

Introduces evidence-based case rates and Prometheus Payment system.

  • The Geisinger Health System’s program established a 40 key process protocol to follow in order to get paid a lump sum for 90 days of care for an elective CABG.
  • The program has been successful: better outcomes, lower overall costs.
  • This has others wondering if Gesinger’s new approach could be expanded to other procedures.

Significance to Literature:

The Geisinger case rate approach is a form of P4P similar to Prometheus.

  • Many P4P programs are changing in scope, performance measures, and magnitude of funding in order to improve efficacy.
  • New models often account for cost efficiency.
  • Models also trend towards global condition based payments such as AMI, DM2, knee replacement (Prometheus, Geisinger) developed on the basis of clinical standards for appropriate care.
  • “Need to distinguish random variation in outcomes and patient mix from variations in practices and avoidable complications.”

Significance to Literature:

Reviews several new models that combine novel reimbursement strategies with built-in quality improvement programs.

  • Outlines the history of P4P in California.
  • Discusses episodes of care reimbursement system in detail while outlining the primary problems including: small numbers, attribution, and inconsistent benefit design.
  • Describes similar payment systems including: bundled payments and clinical process measurement.

Significance to Literature:

"Despite high hopes, performance reward based on episodes of care has proved to be limited by problems of sample size and data completeness."
