Descrizione dettagliata
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.

Cosa sta misurando lo studio?
Misure di risultato primarie
Misura del risultato |
Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Change in overall pain score (Patient Reported Outcomes Measurement Information System (PROMIS)
Lasso di tempo: 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.

Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Change in pain medication
Lasso di tempo: Change from baseline to 3 months
|
Change in pain medication will be evaluated in several manners: change in the opiate prescribed, change from an opiate to a non-opiate; and change in dose of the opiate prescribed
|
Change from baseline to 3 months
|
|
Change in pain score of pain intensity (Patient Reported Outcomes Measurement Information System (PROMIS) subscale)
Lasso di tempo: Change from baseline to 3 months
|
Patient Reported Outcomes Measurement Information System (PROMIS) subscale for pain intensity, with the score ranging from 0 to 100 resulting.
|
Change from baseline to 3 months
|
|
Change in pain score of physical functioning (Patient Reported Outcomes Measurement Information System (PROMIS) subscale)
Lasso di tempo: Change from baseline to 3 months
|
Patient Reported Outcomes Measurement Information System (PROMIS) subscales for physical functioning include pain function, pain interference, pain behavior, sleep disturbance, and sleep-related impairment.
A score of 0 to 100 based on survey responses will be resulted for each subscale.
|
Change from baseline to 3 months
|
|
Change in pain score of emotional functioning
Lasso di tempo: Change from baseline to 3 months
|
Patient Reported Outcomes Measurement Information System (PROMIS) subscales for emotional functioning include fatigue, anxiety, depression, and anger.
A score of 0 to 100 based on survey responses will be resulted for each subscale.
