Outcome Measures

Primary Outcomes (1)

  • Change in Overall Benefit of Analgesic Score (OBAS)

    The overall benefit of analgesia score (OBAS) is a daily multi-dimensional survey that assesses analgesia benefits, opioid-related adverse events (ORAEs), and patient satisfaction. It is a seven-item scale, with items ranging from( 0 = not at all) to(4 = very much). To calculate the Total OBAS score, compute the sum of scores in items 1-6 and add '4-score in item 7'. Low score indicates high benefit.

    baseline, 48 hours following PACU discharge

Secondary Outcomes (3)

  • Change in prescription pattern for postoperative pain control.

    baseline, 48 hours following PACU discharge

  • Change in Opioid requirements

    baseline, 48 hours following PACU discharge

  • Changes in opioid use perioperatively based on pharmacogenomic testing

    baseline, 48 hours following PACU discharge

Study Arms (2)

Pharmacogenomic (PGx) guided

EXPERIMENTAL

Subjects will have Pharmacogenomic (PGx) testing preoperatively. The pharmacists will review results and make recommendations to the anesthesia and orthopedic teams for perioperative anesthesia and analgesia. The teams will use this information to drive clinical decisions as they see fit.

Other: Pharmacogenomic (PGx)Other: Review results

Control

ACTIVE COMPARATOR

Subjects will undergo Pharmacogenomic (PGx) preoperatively but the results will be sealed until completion of treatment and clinicians will not have access to this information. These patients will undergo standard treatment dosing and medication selection.

Other: Pharmacogenomic (PGx)

Interventions

Administer a pharmacogenomics test (buccal swab) during the pre-operative setting

ControlPharmacogenomic (PGx) guided

Pharmacogenomic (PGx) results reviewed by the clinicians during their treatment and the results may guide clinical decisions.

Model Details: All subjects meeting inclusion/exclusion criteria will undergo pharmacogenomic testing. A pharmacist will review the pharmacogemic report and make recommendations for patients in the interventional group. The anesthesiologist and orthopedic surgeon will use that information for preoperative clinical decisions related to anesthesia and analgesia.
