The PROMETHEUS Design Team has developed ten principles for
the development of an Evidence-informed Case Rate (ECR®):
- An ECR® is a global payment for an entire episode of medical
care for a particular payer-provider-patient triad, as
informed by clinical practice guidelines and/or expert
opinion.
- The ECR® starts after a confirmed trigger for that episode
(e.g. a diagnosis) – although the ECR® can then be
paid prospectively as a global fee. In no event does an
ECR® impute event/probability risk to the provider.
- ECRs® are developed based on the quantity and types
of services needed for the treatment of a typical episode
of care, meaning that the episode excludes services provided
for conditions and procedures not related to the index
condition, as well as those for potentially avoidable complications/errors.
This defines the boundaries of expected variation within
a typical ECR®.
- The base quantity of different types of services within
an ECR® is adjusted to account for regional variations in
practice patterns.
- ECRs® are severity adjusted based on the factors outlined
below, which creates clear delineations for risk corridors
for the episode within the normal boundaries of total expected
variation
- patient characteristics
- demographics
- comorbid conditions
- severity of illness
- evidence-informed procedures performed
- evidence-informed pharmacy used
- provider characteristics
- hospital location – rural vs. urban
- hospital type – teaching vs. non-teaching
- hospital size – number of beds, specializations
- physician specialty type – primary care
vs. specialist
- geographic factors
- A stop-loss creates an upper boundary for the expected
variation in any ECR® and insulates providers from any costs
above the stop-loss.
- Care for potentially avoidable complications is accommodated
and paid for through an allowance that is calculated based
on a percentage of the current costs of potentially avoidable
complications. This creates a clear and unambiguous incentive
for providers to reduce those complications. The allowance
is allocated pro rata to each ECR®, taking into account
the severity of the patient treated.
- A margin is built into each ECR® reflecting the importance
for any going concern to have a return on capital assets
invested and a reason to reinvest in business operations.
- Each ECR® is scored and the scores across ECRs® are summed
for each provider into an overall provider-specific scorecard
that informs the providers on the relative effectiveness
and efficiency of the services they have delivered, as
well as the public on the differences among providers.
- With 70% of the provider’s total score based on
what they do and 30% based on what providers that are downstream
from them do, a bonus potential is built into the program
for attaining high quality scores which take into account
performance ratings:
- process measures
- outcomes measures
- using enhanced practice infrastructure - CPOE, EMR,
on-line scheduling
- patient experience surveys
- coordination of care through nurse support, reminder
program
The results of the AMI and Diabetes
ECRs® modeling are fully consistent
with these principles.
This “Playbook” is
version 1.0 of many versions to come that will
make up a complete record for how to model
and construct Evidence-informed Case Rates® for the PROMETHEUS PAYMENT® model[1]. We encourage and
welcome comments and suggestions on how to improve the models
presented herein, fully recognizing that these
models
are likely
to have many
shortcomings
due to: (a) the limitations inherent in the
datasets used,
(b) the judgments made relative to factoring
severity-adjusters, exclusionary rules, triggers and case-breakers,
(c)
the judgments made relative to parsing typical
care and services
from potentially
avoidable complications (PACs). It is our
intent to make this
developmental effort open to all, fully transparent,
and an evolving
set of models that will benefit from the
collective input of health care services researchers and experts
from
all over
the world.
