This is a single-center, prospective, observational study that will compare the blood transfusion rate between intraoperative bleeding severity characterized using the Validated Intraoperative Bleeding Scale (VIBe).
Primary Aim: Assess the association between the VIBe scale and intraoperative and postoperative blood transfusion rates for posterior thoracolumbar spine surgery. Primary Hypothesis: Patients with higher recorded VIBe grades during the five stages of spine surgery (exposure, decompression, instrumentation, fusion, and closing) will have a higher rate of receiving blood transfusions. Secondary Aims: Determine the association between the VIBe scale and other postoperative outcomes and complications.

Receiving Perioperative Blood Transfusion
The main outcome will be whether or not the patient received a blood transfusion during the surgery or the postoperative hospitalization period.
Time frame: From day of surgery until discharge from hospital, assessed up to 2 weeks following surgery.
Total Estimated Blood Loss During Surgery (mL)
The secondary outcome will be total blood loss during surgery assessed using anesthesiology and surgeon reported estimated blood loss (mL).
Time frame: From the start to the end of surgery, assessed up to 1 day following surgery when estimated blood loss is reported and documented.
