Nonspecific Pain Post Traumatic Injury

Brief summary

This is a comparative effectiveness study of current pain management strategies in acutely injured trauma patients. Two different multi-modal, opioid minimizing analgesic strategies will be compared \[original multimodal pain regimen (MMPR) compared to multi-modal analgesic strategies for trauma (MAST) MMPR\].

Design outcomes

Primary

MeasureTime frameDescription
Opioid Use Per Dayuntil discharge from hospital or 30 days post admission (whichever is sooner)Opioid use per day is calculated by tallying the dose equivalency of all opioids received and dividing by the number of days hospitalized. Morphine milligram equivalents (MME) per day are reported.

Secondary

MeasureTime frameDescription
Pain as Assessed by Score on the Behavioral Pain Scale (BPS)until discharge from hospital or 30 days post admission (whichever is sooner)An average will be calculated of the daily score on the Behavioral Pain Scale (BPS). BPS score ranges from 3-12, with higher scores indicating worse pain. This assessment is used in non-verbal participants.
Number of Participants Discharged From the Hospital With an Opioid PrescriptionUp to 30 days
Number of Participants With Any Opioid-related Complicationsuntil discharge from hospital or 30 days post admission (whichever is sooner)Opioid-related complications include ileus, aspiration, unplanned intubation, unplanned admission to an intensive care unit, and use of an opioid-reversal agent.
Overall Costsuntil discharge from hospital or 30 days post admission (whichever is sooner)the costs associated with the overall hospitalization or the first 30 days (whichever is sooner) related to post trauma care and complications incurred.
Pharmacy Costsuntil discharge from hospital or 30 days post admission (whichever is sooner)The costs of the pain medications given during the specified time period.
Pain as Assessed by Score on the Numeric Rating Scale (NRS)until discharge from hospital or 30 days post admission (whichever is sooner)An average will be calculated of the daily numeric rating scale (NRS) for pain (0=no pain, 10=worst pain). This assessment is used in verbal participants.
Number of Hospital Days30 daysThe number of days the patient was hospitalized post injury or up to 30 days (whichever is sooner). Zero-inflated models are presented as estimated marginal means (95% Credible Interval). The data reported as mean actually refers to marginal mean, and the data reported as 95% Confidence Interval actually refers to a 95% Credible Interval.
Number of Intensive Care Unti (ICU) Days30 daysThe number of days the patient was in the ICU post injury or up to 30 days (whichever is sooner). Zero-inflated models are presented as estimated marginal means (95% Credible Interval). The data reported as mean actually refers to marginal mean, and the data reported as 95% Confidence Interval actually refers to a 95% Credible Interval.
Degree to Which Function is Limited by Pain as Assessed by Percent of Predicted Daily Incentive Spirometry Volumes (Which is Based on Ideal Body Weight)until discharge from hospital or 30 days post admission (whichever is sooner)Clinical based pain scores ranging from 0 to 10 will be assessed at regular intervals throughout the hospitalization.
Degree to Which Function is Limited by Pain as Indicated by Number of Participants Who Failed to Work With Physical Therapist Due to Painuntil discharge from hospital or 30 days post admission (whichever is sooner)
Number of Ventilator Days30 daysThe number of days the patient on a ventilator post injury or up to 30 days (whichever is sooner).
