Primary Outcome Measures
NameTimeMethod
Numerical Rating Scale (NRS) Pain Intensity Scale Scorepostoperative time intervals: 2 hours (baseline), 6 hours, 12 hours, 24 hours, 36 hours, 48 hours

Mean pain intensity scores post-operatively using 11-point Numerical Rating Scale (NRS) (scale ranges from 0 to 10, and higher score means higher pain)

Secondary Outcome Measures
NameTimeMethod
Length of Hospital StayAfter surgery until discharge, up to 10 days
Time to first ambulation after surgeryAfter surgery until discharge, up to 10 days
Quality of Life (EuroQol Questionaire) scale score48 hours, up to 1 month after surgery

Participants rate their quality of life using the EuroQol-5D-5L questionnaire (scale from 1 to 5, 1 = no problem, 5 = severe problem)

Cumulative opioid consumptionAfter surgery until discharge, up to 10 days

All opioid medications the patient takes after surgery will be converted to a morphine equivalent dose.

Healthcare cost during admissionAfter surgery until discharge, up to 10 days

Cost of hospital stay obtained from participant's Electronic Medical Record

Number of participants with treatment-related hepatic toxicitypostoperative time intervals: 2 hours(baseline), 24 hours, 48 hours

Values above the normal range for any of these four lab tests (AST, ALT, INR, bilirubin) will be considered hepatic toxicity

Number of participants with treatment-related skin rashAfter surgery until discharge, up to 10 days, whichever is first

Per clinician assessment

Change in Patient Global Assessment Scale Scorepostoperative time intervals: 2 hours, 6 hours, 12 hours, 24 hours, 36 hours, 48 hours

Participants report their overall wellbeing as measured by 5-point Likert scale (ranging from 0-5, where 1=very well; 2=well; 3=fair; 4=poor; and 5=very poor)

Time to first additional opioid medication doseAfter surgery until discharge, up to 10 days

Additional opioid pain medication as requested by the participant which is not scheduled

Total number of additional opioid medication dosesAfter surgery until discharge, up to 10 days

Additional opioid pain medication as requested by the participant which is not scheduled
