Association of Mortality and Charlson Comorbidity Index in Surgical Spinal Trauma Patients at a Level I Academic Center.

Objectives: The Charlson Comorbidity Index score (CCI) records the presence of comorbidities with various weights for a total score to estimate mortality within 1 year of hospital admission. Our study sought to assess the association of CCI with mortality rates of patients undergoing surgical intervention.

Study Design: Retrospective study.

Elective spine surgery with continuation of clopidogrel anti-platelet therapy: Experiences from the community.

Purpose: This retrospective study aimed to assess the feasibility of continuing clopidogrel therapy during the perioperative period in elective cervical and thoracolumbar surgery.

Methods: After IRB approval, medical records of patients requiring one or two-level surgery over a two-year period (2015-2017) while receiving clopidogrel were reviewed for relevant outcomes. Over the same period, a control group of patients not receiving clopidogrel perioperatively was formed.
