Healthcare utilization cost higher for patients using problematic medications compared to patients using better tolerated medications.

“Subjects whose medication regimen included a medication identified by the gene-based interpretive report as most problematic for that patient and are in the ‘red bin’ (medication status of ‘use with caution and frequent monitoring’), had 69% more total health care visits, 67% more general medical visits, greater than three-fold more medical absence days, and greater than four-fold more disability claims than subjects taking drugs categorized by the report as in the green bin (‘use as directed’) or yellow bin (‘use with caution’).”

79% of clinicians made decisions congruent with report recommendations, reducing overall post-test medication costs and improving adherence.

“Patients who received pharmacogenomic (PGx) testing saved $1035.60 in total medication costs (both CNS and non-CNS medications) over 1 year compared to the non-tested standard of care cohort (p = 0.007). PGx testing improved adherence compared to standard of care (ΔPDCCPGx = 0.11 vs ΔPDCTAU = −0.01; p < 0.0001). Pharmacy cost savings averaged $2774.53 for patients who were changed to a combinatorial pharmacogenomic (CPGx) congruent medication regimen, compared to those who were not (p < 0.0001)."

CPGx improved treatment response rate by 70%, resulting in patient cost savings over lifetime.

“CPGx improved the treatment response rate by 70% (1.7 times as high as that with TAU), increasing QALYs by 0.316 years. With these health benefits, CPGx is expected to save $3711 in direct medical costs per patient and $2553 in work productivity costs per patient over the lifetime. The cost-effectiveness of CPGx testing was robust over a wide range of variation in the input parameters, including the scenario when testing efficacy was set to its lower limit.”
