Opioid Sparing Pain Management Strategy


The purpose of this research study is to compare the amount of morphine milligram equivalents consumed post operatively until discharge between the control cohort and intervention cohort.

Full Title of Study: “A Multi-modal, Opioid Sparing Pain Management Strategy in Cardiac Surgery”

Study Type

  • Study Type: Observational
  • Study Design
    • Time Perspective: Retrospective
  • Study Primary Completion Date: April 30, 2019

Detailed Description

Retrospective data will be collected on patients admitted to Prisma Health-Upstate Greenville Memorial Hospital in the Cardiovascular Intensive Care Unit following cardiovascular surgery. They will be divided into two cohorts, a control cohort from September 1, 2018 – October 31, 2018 and an intervention cohort from March 1, 2019 – April 30, 2019. A study investigator will assess each participant's electronic medical record through the electronic medical record database – EPIC to determine eligibility per the protocol. Demographic information will be collected, including age, date of birth, race, sex, height, weight, and ethnicity. Extubation and reintubation status will be collected along with medical history, type of cardiovascular procedure, medications, length of stay, pain scores, complications, and labs.


  • Other: Multi-modal Opioid Sparing Pain Management Protocol
    • Incorporating multimodal opioid sparing ERAS techniques for cardiac surgery patients should show a decrease in the amount of opioids received, reduction in incidence of chronic pain, ileus, delirium, and potential for opioid addiction post-operatively. Between the dates of November 2018 through February 2019, a multi-modal, opioid sparing pain management protocol was evolving and a protocol was put into place. This study will compare outcomes before and after implementation of the protocol between the dates of September 1, 2018 – October 31, 2018 and March 1, 2019 – April 30, 2019.
