MD Labs Has Turnkey PGx Program for Hospital Implementation
Target Audience: Hospital Executives; Hospital-based Cardiologists, Quality Directors and Pharmacists
There is mounting evidence on the cost saving opportunities of applying Pharmacogenetic (PGx) testing following percutaneous coronary intervention (PCI) and coronary stent procedures. In concert with an interventional cardiologist, MD Labs has developed a PGx protocol for Catheter Labs that U.S. hospitals are in the process of adopting. This is of particular importance given the new CMS Cardiac Bundle being introduced into hospitals.
The benefits of this protocol are bolstered by studies such as the one in Expert Opinion on Drug Metabolism & Toxicology “The pharmacogenetic control of antiplatelet response: candidate genes and CYP2C19” (July 2015) which surveyed clinical outcomes of using pharmacogenetics to guide antiplatelet therapy used for preventing ischemic events in patients with acute coronary syndromes (ACS), percutaneous coronary intervention (PCI) and other indications. The pharmacogenetics of available antiplatelet agents – aspirin, clopidogrel, prasugrel and ticagrelor – were analyzed.
CYP2C19 Implicated in Clopidogrel Response Variability
The authors found abundant data in its literature meta-analysis supporting the clinical validity of CYP2C19 and clopidogrel response variability among ACS/PCI patients, stating “[t]he increased risks for reduced clopidogrel efficacy among ACS/PCI patients that carry CYP2C19 loss-of-function alleles should be considered when genotype results are available.” It was also found that “insufficient candidate genes” have thus far been implicated for prasugrel or ticagrelor.
The Clinical Utility of Pre-emptive PGx Testing for Plavix
The authors concluded by citing the need for pre-emptive PGx testing for clopidogrel (Plavix), for which they found a “clear association” with CYP2C19, explaining that pre-emptive pharmacogenetics testing would circumvent the issue of the need for rapid turnaround which is one of the frequently cited barriers to implementing CYP2C19 genetic testing for antiplatelet therapy.
A pre-emptive approach – as offered by genotyping platforms such as MD Labs’ Rxight® – would integrate CYP2C19 genotype data into cath labs and the patient EMRs to alerts prescribers through clinical decision support at the point-of-care if and when clopidogrel is ordered and the patient carries an at-risk CYP2C19 genotype.
“Although this model has inherent challenges … pre-emptive CYP2C19 genetic testing has recently been deployed at several academic medical centers,” the authors stated. The authors called for “an ongoing effort towards the application of clinical pharmacogenetics by increasing clinician education and acceptance.”
CMS Cardiac Bundle Paves Way for PGx Testing for ACS Patients
With the coming of the CMS Cardiac Bundle program for hospitals (effective Oct 1, 2017) there is now added financial incentive to implement PGx testing as part of the standard of care for cardiac patients about to undergo antiplatelet pharmacotherapy.
1,200 participating hospitals in 98 metropolitan areas in the U.S. are mandated to be held financially accountable for the costs of heart attacks and bypass surgery under the CMS protocol for cardiac care. There is therefore significant incentive to reduce costs through various measures such as integrating PGx testing into standing orders for coronary stent procedures and percutaneous coronary interventions (PCIs). For these treatments, anti-platelet pharmacotherapy is an established standard of care to reduce thrombotic risk, with Plavix (clopidogrel) as a first-line agent tested.
Implementing PGx in Your Hospital
A crucial part of MD Labs’ Rxight® turnkey program is the incorporation of PGx trained and certified pharmacists as part of the protocol to serve as expert resources for physicians and to provide consultations with the patients; pharmacist involvement in patient care has been shown to reduce hospital readmission rates. DNA test kits are provided by MD Labs, and results are accessible via online provider and patient portals.
