Purpose: The purpose of this project was to determine whether the use of the modified Northwestern high risk spine protocol in patients undergoing multilevel spinal fusion surgery would result in improved transfusion practices.
Design: Preimplementation and postimplementation design.
Methods: A laboratory monitoring and transfusion guideline protocol was implemented in patients undergoing multilevel spinal fusions. Data were collected via a manual retrospective chart review of the electronic medical record before and after implementation of the protocol.
Findings: Laboratory values were monitored at guided intervals. There was a statistically significant (P = .004) decrease in the mean hemoglobin value at which a packed red blood cell transfusion was initiated.
Conclusions: Through the use of the protocol, laboratory value monitoring provided quantitative data to aid and improve clinical decision making for practitioners in the perioperative period.
Keywords: laboratory monitoring protocols; multilevel spine surgery; patient outcomes; postoperative disposition; transfusion guidelines.
