Trial outcomes
Primary outcomes
1
Chronic pain patient preferences of pain medications regarding pain relief relative to the side effects using numeric rating scales (adaptation of the outcome prioritization tool).
Using numeric rating scales from 0 to 10 (adaptation of the outcome prioritization tool) to assess patient perceived importance of analgesic effect relative to not having the following side effects: fatigue, drowsiness (sleepiness), dizziness, difficulty concentrating, nausea, constipation (difficulty passing stools), dry mouth, unintentional weight gain, addiction (medication craving). Higher scores mean the specific outcome is a higher priority for the participant.
Time frame
Single measure at a time selected by the participant within the study period (up to 15 months).Secondary outcomes
1
Analgesic side effect burden measured by numeric rating scales (NRS)
Using numeric rating scales, from 0 to 10, to assess current burden of the following analgesic side effects: fatigue, drowsiness (sleepiness), dizziness, difficulty concentrating, nausea, constipation (difficulty passing stools), dry mouth, unintentional weight gain, addiction (medication craving). Higher scores mean being more affected by the side effects.
Time frame
Single measure at a time selected by the participant within the study period (up to 15 months).2
Patient pain levels in the last 24 hours and pain body location and its impact on functioning measured by the Brief Pain Inventory short form (BPI-SF).
Time frame
Single measure at a time selected by the participant within the study period (up to 15 months).3
Overall pain levels in the past 7 days measured by a numeric rating scale.
Numeric rating scale from 0 to 10, with higher scores meaning higher pain levels.
Time frame
Single measure at a time selected by the participant within the study period (up to 15 months).4
Overall sleep quality in the past 7 days measured by a numeric rating scale.
Numeric rating scale from 0 to 10, with higher scores meaning better sleep.
Time frame
