This multicenter Registry is to assess whether the use of pharmacogenomic data results in a meaningful change in a subject's drug or dose regimen. In addition, the Registry will evaluate the relationship between adverse drug reactions (ADR) and genotype and assess resource utilization (emergency department visits and hospitalizations) associated with ADR.
Occurrence of meaningful change in drug regimen [ Time Frame: 60 days ]
The primary endpoint of the study is the binary occurrence of meaningful change in drug regimen, defined in each subject when:
A genotype known to affect a drug the subject is taking is identified, and
The subject's treating physician makes at least one drug regimen change in concordance with the PharmD recommendations.
Secondary Outcome Measures
Change in the regimen of drugs controlled by genes of interest over the 12 months prior to enrollment and change in the regimen of drugs controlled by genes of interest over the 60 days following receipt of pharmacogenetic test results. [ Time Frame: 60 days ]
Number of ADR per month over the 12 months prior to enrollment and number of ADR per month over the 60 days following receipt of pharmacogenomic test results. [ Time Frame: 60 days ]
Frequency of genome-based PharmD recommendations to alter drug or dose. [ Time Frame: 60 days ]
Emergency department visits and hospitalizations [ Time Frame: 60 days ]
Emergency department visits over the 12 months prior to enrollment, emergency department visits over the 60 days following receipt of test results, hospitalizations over the 12 months prior to enrollment, and hospitalizations over the 60 days following receipt of test results.
