ABSTRACT
The perioperative management of patients medicated with antithrombotic agents who require elective spinal surgery is extremely challenging because of the increased risk of surgical bleeding and the concurrent need to minimize the thromboembolic risk. The aims of the present systematic review are to: (1) identify clinical practice guidelines (CPGs) and recommendations (CPRs) on this topic and (2) assess their methodological quality and reporting clarity. An electronic systematic search of the English Medical Literature up to January 31, 2021 was conducted using PubMed, Google Scholar, and Scopus. Two raters assessed the methodological quality and reporting clarity of the gathered CPGs and CPRs using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) tool. The agreement between the two raters was assessed using Cohen’s kappa. Of the initially gathered 38 CPGs and CPRs, 16 fulfilled our eligibility criteria and were evaluated using the AGREE II instrument. The reports published by “Narouze 2018” and “Fleisher 2014” were scored as being of “high-quality” and having an adequate interrater agreement (Cohen’s kappa ≥0.60). Overall, the AGREE II domains of “clarity of presentation” and “scope and purpose” yielded the highest scores (100%), whereas the domain “stakeholder involvement” scored the lowest score (48.5%). The perioperative management of antiplatelet and anticoagulant agents in elective spine surgery may be challenging. Because of the lack of high-quality data in this field, uncertainty remains regarding the optimal practices to balance the risk of thromboembolism against that of bleeding.
