Target Recruitment
800
Inclusion Criteria
  • Persons receiving ongoing oncology care at the University of Chicago Medical Center for whom near-future pain opioid pain medication therapy is anticipated
  • Subjects must be at least 18 years of age.
Exclusion Criteria
  • Subjects taking an opioid at the time of enrollment, or within the past 30 days
  • Subjects who are currently undergoing palliative radiation
  • Subjects who have undergone, or are being actively considered for, bone marrow, liver or kidney transplantation.
  • Subjects with a history of or active blood cancer (e.g., leukemia).
  • Chronic kidney disease, as defined by Glomerular filtration rate (GFR) < 30/mL/min/1.73m2, due to the risk of decreased drug excretion.
  • Liver dysfunction, as defined by the following laboratory values, due to the risk of decreased drug metabolism: Total bilirubin greater than or equal to1.5 mg/dL, Aspartate Aminotransferase (AST) and Alanine Aminotransferase (ALT) greater than or equal to 2.5 X upper limit of normal*. (*Aspartate Aminotransferase (AST) and Alanine Aminotransferase (ALT) \ greater than or equal to 5 X upper limit of normal if hepatic metastases are present).
  • Inability to understand and give informed consent to participate in the opinion of the investigator
  • Subjects who are known to be pregnant at the time of enrollment
  • Subjects who have previously or are currently enrolled in another institutional pharmacogenomic genotyping study, or are known to have previously undergone pharmacogenomic genotyping for the gene(s) of interest via another commercial or other means.

PGx ArmPharmacogenomic (PGx) results.PGX information is provided to clinicals to inform opioid dosing and selection.
Primary Outcome Measures
NameTimeMethod
Pain control.45 days

Measuring changes in composite pain intensity rating via the numeric rating scale:

* Brief Pain Inventory-Short Form (BPI-SF)

* Score range: 0 (no pain) to 10 (most pain)

* Composite pain intensity score (mean of worst, least, average, and current pain)

From baseline to day 45 in patients receiving an index opioid prescription for codeine, tramadol, or hydrocodone.

Secondary Outcome Measures
NameTimeMethod
Type of First Opioid PrescribedFrom enrollment until study end (up to 5 years)
Pain Medication Regimen Changes45 days

Pain medication regimen changes will be assessed for patients who were taking an opioid metabolized primarily by CYP2D6. Pain medication regimen changes from baseline to day 45. The timing of subsequent changes in pain regimes after initial opioid selection will also be recorded.

Hospitalization or Emergency Visit for Pain Control45 days

The rates of hospitalization and emergency room visits for pain are examined with the rates of increased utilization of health care resources, such as emergency department visits, hospitalizations, and pain consultations. Rates of hospitalization or emergency room visits from baseline to day 45.

Cumulative Morphine Equivalents Required45 days

Cumulative Morphine Equivalents will be defined as total amount of opioids taken by a patient that is converted into its morphine equivalent. Dose and frequency of each opioid given during 45 days after its index prescription will be considered during calculation to give final values, which will be compared to Cumulative Morphine Equivalents for Control arms treated per standard of care.
