Design outcomes

Primary

MeasureTime frameDescription
SPID-4848 hoursSum of Pain Intensity Difference over 48 hours (SPID-48), calculated from pain intensity scores measured using the Numeric Rating Scale (NRS; 0-10 points), where 0 indicates no pain and 10 indicates the worst possible pain. SPID-48 represents the time-weighted sum of pain intensity differences from baseline across the 48-hour assessment period. Higher SPID-48 values indicate greater pain relief (better outcome).

Secondary

MeasureTime frameDescription
Responder rate48 hoursA patient is a responder if their final time-weighted Sum of Pain Intensity Differences from baseline (SPID-48) corresponds to, or is greater than, a 30% improvement.
Time to rescue pain medication use48 hours
Proportion of rescue pain medication use48 hours
Total rescue pain medication use48 hours
