To adequately assess postoperative pain in the coronary artery bypass surgical population a multicentered retrospective chart review was carried out; the study utilized a nonexperimental comparative descriptive study design. The retrospective review was conducted over a six-month time frame, consisting of June 2017 through November 2017, at two hospitals within the same organization. The data collection process began in late December of 2017 and January of 2018. The assessment of postop pain was performed by using a standard 11-point numeric pain rating scale on post extubation day one and the day of discharge.

Inclusion Criteria:

• Patients who had an isolated coronary artery bypass surgery at Charlotte Medical Center (CMC) and CMC-Pineville
• Minimally invasive cardiac surgery
• Traditional sternotomy cardiac surgery

Exclusion Criteria:

• Documented history of any chronic pain syndromes requiring active treatment
• The "relative" recent requirement of narcotic analgesic use for pain relief prior to operation
• Any CABG operation that inadvertently resulted in an operative surgical complication
• Patient cases that resulted in a readmission within 30 days from surgery.

The retrospective review was conducted over a six-month time frame, consisting of June 2017 through November 2017, at two hospitals within the same organization. One of the hospitals was a level one trauma center in the center of a major southeastern metropolitan area, and the second was a community hospital within the suburbs of the same city's geographic limits. All included patients fit the above inclusion and exclusion criteria per the aforementioned time frame and involved healthcare centers.

If requested we would not mind providing guidance on postoperative pain assessments/likert scales.
