ER visits decline 71%, hospitalizations 39% in elderly patients evaluated by predictive medication analytics system and DNA testing
SEATTLE, WASHINGTON; Nov. 12, 2015 – YouScript predictive medication analytics, a clinical decision support tool used by doctors to guide genetic testing and improve drug treatments, has been shown to cut ER visits by almost three-quarters and reduce hospitalizations by more than one-third in elderly patients taking multiple medications.
Researchers from the University of Utah compared those who received YouScript-guided genetic testing and analysis in a prospective group to those who did not in a matched retrospective cohort. The retrospective cohort was obtained from Inovalon’s More2 Registry, a large nationally representative, de-identified claims database. Researchers devised this strategy to meet the challenge of providing closely matched controls to the elderly patients taking multiple medications, also called polypharmacy.
YouScript was shown to reduce ER visits by 71 percent and hospitalizations by 39 percent in the tested population compared to the statistically matched group.
“To our knowledge, this is the first study to demonstrate the potential of a technology to reduce the adverse drug event epidemic caused by polypharmacy,” said Howard Coleman, co-founder and CEO of Seattle-based Genelex, which invented the YouScript system.
“Designing a study capable of tackling the polypharmacy problem was a major challenge, and our hats are off to the University of Utah scientists and others who helped with the study design.”
The data showed YouScript prevented one hospitalization for every 16 patients tested, and one ER visit for every nine tested. Researchers estimated potential cost savings per patient in the tested group at $218 in just four months. The results of this IMPACT study (Improving Medication Protocols and Abating Cost of Treatment), a collaboration of researchers at the University of Utah and Genelex Corporation, were published October 21, 2015, in the Journal of Medical Economics.
The YouScript system combines comprehensive predictive medication management analytics with pharmacogenetic testing, or DNA drug-sensitivity testing as it is also known, to analyze the complex web of medication and genetic interactions affecting how patients respond to drug treatments. The software analyzes patient medication regimens and genetic test results to predict the potential for negative side effects and treatment failure.
When potential problems are identified, YouScript suggests alternative medications with reduced interaction risk, while taking into account all other relevant medications and genetic factors. The testing reveals natural variations present in more than 90 percent of people that determine how the body processes more than three-quarters of commonly prescribed medications.
The study examined two groups of 65-and-older patients taking three-or-more medications:
- The first group, a prospective patient registry, received testing for differences in six liver enzymes that process most commonly prescribed drugs. YouScript analytics were then used to analyze the test results, and a clinical pharmacist provided personalized dose change recommendations.
- The second group, a matched untested control group, was obtained from a large healthcare data warehouse.
The study compared healthcare resource utilization and estimated costs between the two groups to determine the impact of YouScript testing and analysis. Genelex provided an unrestricted research grant to fund the study.
“Real world evidence is limited in the field of pharmacogenetic testing with clinical decision support. This study provided an innovative methods approach to provide preliminary data to support health technology assessment for public and private payer reimbursement decisions,” said primary investigator Dr. Diana Brixner, PhD, RPh, Professor of the Department of Pharmacotherapy at the University of Utah College of Pharmacy.
“Our results warrant contingent reimbursement and further validation through a randomized trial in a unified population.”
Polypharmacy in the Elderly
Polypharmacy has become one of the most serious medical problems facing the elderly today. On average, individuals 65 to 69 years old take 14 different prescribed drugs per year, while those 80 to 84 take an average of 18.
Interactions between drugs are a well-known cause of negative side effects but are in the minority compared to the cumulative effective of drug-drug, drug-gene and drug-drug-gene interactions that are taken into account by the YouScript system. These potential interactions involving genetics further increase the risk of unintended drug treatment consequences, especially in the elderly.
The potential cost-savings that can result from widespread deployment of the YouScript system, in addition to other medication management advances, is significant. According to the Centers for Disease Control and Prevention, adverse drug events cost the U.S. health system approximately $3.5 billion annually.1
Limited Medicare Coverage
The growing body of evidence supporting the importance of genetic variation and drug response may assist Medicare in reconsidering the currently limited coverage of many of these tests. Payment denial could impact as many as 19 million of the 49 million Medicare beneficiaries in the U.S. who are at special risk of costly adverse drug events.2
“If we extrapolate these results to all 52 million Medicare recipients, it would mean almost $1 billion in predicted savings,” Genelex Chief Operating Officer Kristine Ashcraft said.
“We look forward to working with Medicare to further deploy this technology to improve the lives of our most at-risk seniors while reducing healthcare costs.”
The study results came as no surprise to Elise Astleford, a 74-year-old Washington State resident whose life was changed by the YouScript system. YouScript pharmacogenetic testing revealed that her genetic makeup was likely causing her to poorly process a common antihistamine, resulting in forgetfulness and what appeared to her to be the beginnings of dementia.
After Astleford was taken off the medication, her memory returned to normal. Now Astleford brings her YouScript test results with her to every doctor visit.
“I just believe in it because I feel so much more confident, and I feel I’m armed for my own benefit whenever a doctor wants to prescribe me a new drug,” Astleford said.
“For me, it’s the peace of mind that’s quite wonderful.”
