Relationship Between Clinical Decision Support Systems (CDSS) & Radiology Must Evolve

Clinical decision support system (CDSS), an early entrant to healthcare IT, can reduce mistakes in medication administration, encourage practice standardization, and reduce duplication or unnecessary performance of diagnostic tests. When neatly integrated into an electronic health record platform, CDSS can facilitate evidence-based clinical decisions. Built on a backbone of algorithms, rules and alerts, CDSS is a cornerstone of patient safety, healthcare quality, and cost-effective care.

But CDSS has been largely limited to prescriptions, laboratory tests and treatment protocols. This is especially true in the outpatient setting. Building on this functionality, Congress upped the ante for CDSS with the Protecting Access to Medicare Act (PAMA). Passed in April 2014, the immediate effect of the law was to forestall implementation of the SGR. Nevertheless, PAMA is not limited to issues of physician reimbursement. It also details a mandate meant to change physician behavior – specifically regarding the utilization of high-end imaging studies in the outpatient setting.

One of the nearly 40 sections of this law, Section 218, outlines an approach effectively aimed at decreasing utilization by encouraging adherence to specialty-vetted clinical practice guidelines for the ordering of these costly tests. These practice guidelines, or appropriate use criteria, are meant to drive the development and implementation of radiology decision support tools. This has become a major challenge to entities that provide radiology services – the mandate to provide CDSS to referring physicians.

Set to take effect Jan. 1, 2017, PAMA is reminiscent of the EHR Incentive Reimbursement Program (Meaningful Use). Since its inception, Meaningful Use has been a puzzle to most who practice radiology. MU’s core objectives comprise the build of a replete centralized patient health record. But, unlike other disciplines in medicine, EHR design does not conform to radiology workflow and process. With the passing of this law, PAMA is something of a declaration that RIS and PACS do not go far enough to improve the health of our patients and to decrease healthcare expenditures.

A close reading of the law reveals three parallel strategies:

Ordering physicians must confirm that the appropriate use criteria are consulted when ordering CT, MRI, nuclear and PET studies. Important to note is that adherence will not be required. However, it will be measured by CMS.
Providers of radiology services will be required to offer CDSS to ordering physicians. The law explicitly states that physicians who provide diagnostic interpretation will be paid only for those claims that confirm a certified CDSS was used.
Those ordering physicians identified as outliers as measured by CMS in 2018-9 will be subject to a prior authorization process beginning Jan 1 2020.

The threat of prior authorization is a real, however soft, incentive to change one’s behavior. Financially speaking, a greater burden must be borne by radiology services given the mandate to offer CDSS to referring providers.

In order to be able to execute on these changes to practice, PAMA defines a relatively tight timeline. CMS is required to finalize the terms of the appropriate use criteria no later than November 15, 2015. Once published, CMS will have until April 1, 2016 to approve clinical decision support systems for deployment. And on January 1, 2017, all ordering providers will be expected to consult a CDSS and radiology services will be required to confirm availability, use, and level of adherence to the appropriate use criteria. This attestation will be required on all Medicare claims for reimbursement.

My conversations with colleagues locally and across the country make me think that planning for this change is barely nascent in most communities. I expect this topic is going to heat up soon, especially given the cost and complexities involved. Time will tell.
