Detailní popis
Codeine and tramadol are opioid analgesics that depend on cytochrome P450 2D6 (CYP2D6) for bioactivation to morphine and O-desmethyltramadol, respectively. Morphine and O-desmethyltramadol have much greater affinity for the opioid receptor and thus are more powerful analgesics.
Individuals with genotypes associated with low CYP2D6 activity (poor metabolizers) are unable to convert sufficient amounts of codeine or tramadol to their active metabolites and may fail to derive sufficient pain relief. At the opposite extreme, individuals with genotypes associated with increased CYP2D6 activity (ultra-rapid metabolizers) are at risk for serious toxicity with usual codeine or tramadol doses.
The CYP2D6 genotype also has implications for response to other drugs, such as tricyclic antidepressants (TCAs), which are commonly used for neuropathic pain.
Patients will be recruited from family medicine clinics, serving as either implementation sites or control sites. Patients from implementation sites will undergo CYP2D6 genotyping, with results placed in the medical record to assist with prescribing of pain medications. Pain medications prescribed from baseline to 3 months will be assessed through medical record review. A pain assessment questionnaire will be administered to patients enrolled from both sites at baseline and 3 months.
At the end of the study, a 20-item survey will be administered to physicians at the implementation sites. We will assess whether having CYP2D6 genotype results is useful to inform prescribing decisions for pain medication from the physician's perspective.
We will also assess medicines prescribed to patients enrolled from both sites over the 12-month period after enrollment from medical record review and determine the number of patients who were prescribed a medication that has genetic information in its FDA-approved label.

Co je měření studie?
Primární výstupní opatření
Měření výsledku |
Popis opatření |
Časové okno |
|---|---|---|
|
Change in overall pain score (Patient Reported Outcomes Measurement Information System (PROMIS)
Časové okno: Change from baseline to 3 months
|
Patient Reported Outcomes Measurement Information System (PROMIS) measures will be used to assess pain intensity, physical functioning, and emotional functioning.
There are 10 subscales on the PROMIS questionnaire that address the domains of pain, pain functioning, and emotional functioning.
At least 4 (and up to 30) items are used to derive a score for each subscale.
A computer adaptive version of the questionnaire based on item response theory will be used to administer the survey.
A score of 0 to 100 based on survey responses will be resulted for each subscale.
