Conditions

Post Operative Pain

Brief summary

The purpose of this study is to evaluate the effectiveness and safety of tramadol and oxycodone therapy in comparison to oxycodone alone as part of a multimodal pain regimen to reduce postoperative opioid consumption, pain, minimize adverse events and complications for primary total knee arthroplasty (TKA) and primary total hip arthroplasty (THA).

Interventions

DRUGOxycodone

Patients will receive oral Oxycodone only to treat post-operative pain: Oxycodone 5mg * Patients ≤75 years old: 5mg or 10 mg PO every 4 hr as needed * 5 mg for pain rated 4-6 * 10 mg for pain rated 7-10 * Patients \>75 years old and/or sensitive to opioids or sedatives: 2.5mg or 5mg every 4hr as needed * 2.5mg for pain rated 4-6 * 5mg for pain rated 7-10

DRUGTramadol and Oxycodone

Patients will receive a combination of Tramadol and Oxycodone to take orally to treat post-operative pain: Tramadol 50mg * Patients ≤75 years old: 50 mg for pain rated 4-6; 100 mg for pain rated 7-10 * Patients \>75 years old and/or sensitive to opioids or sedatives; use 50 mg * Dosing is every 8 hours as needed. Cumulative dose not to exceed 400mg in 24 hours Oxycodone 5mg * Patients ≤75 years old: 5mg or 10 mg PO every 4 hr as needed if still having pain after maximum tramadol administration * 5 mg for pain rated 4-6 * 10 mg for pain rated 7-10 * Patients \>75 years old and/or sensitive to opioids or sedatives: 2.5mg or 5mg every 4 hr as needed if still having pain after maximum tramadol administration * 2.5 mg for pain rated 4-6 * 5 mg for pain rated 7-10

Design outcomes

Primary

MeasureTime frameDescription
Cumulative opioid consumption during the first 30 days30 daysTotal amount of opioid medication taken for the first 30 days following surgery, reported in milligrams (mg)

Secondary

MeasureTime frameDescription
Cumulative opioid consumption during the first 90 days90 daysTotal amount of opioid medication taken for the first 90 days following surgery, reported in milligrams (mg)
Postoperative opioid refills within 90 days90 daysTotal number of opioid medication refills within 90 days post surgery
Number of unused opioid pills90 daysTotal number of unused opioid pills unused after 90 days
Change in Visual Analogue Scale (VAS) pain scoresDaily for 90 daysPain values reported by participants will be assessed using the 100-mm Visual Analogue Scale (VAS). The VAS line will be 100 mm long with no intermediate delineations. Each end will be marked with "no pain" on the left, and "worst possible pain" on the right. Participants will identify their pain level by indicating a point on the line between each end. That point will be measured from the "No pain" end, and the number of millimeters will be reported as the pain score.
Number of complications90 daysTotal number of complications experienced post-operatively, complications include stiffness, VTE, GI hemorrhage, falls, ileus, dizziness, changes in vision, and miosis.
Number of emesis episodes90 daysPostoperative nausea and vomiting will be measured by total number of emesis episodes
Rate of antiemetic use90 daysTotal number of times patients require use of antiemetics for nausea or vomiting
Satisfaction survey scores90 daysPatients will be provided with a satisfaction survey 90 days post-surgery. The survey consists of 2 questions rated on a Likert scale measuring understanding and confidence in medication use, and one yes/no question. The Likert scale questions are ranked from "0" - no understanding/low confidence to "10" - full understanding/high confidence. Higher scores indicate greater satisfaction with the prescribed opioid therapy plan.
Length of StayPost-operatively, up to 90 daysTotal number of days patients stay inpatient
