Risk Factors for Blood Transfusion With Primary Posterior Lumbar Fusion

“…[3][4][5] This study used a large, national sample of primary posterior lumbar fusion patients to determine patient and operative factors associated with blood transfusion, as well as to find associations between receiving a blood transfusion and postoperative adverse outcomes.…”

“…2 There is little information available in the literature about preoperative factors associated with blood transfusion during or after primary posterior lumbar fusion. [3][4][5] Preoperative assessment of surgical risk factors for spine surgery is crucial because it helps decrease the risk of surgical complications and their associated healthcare costs. 6 In order to standardize preoperative risk assessment for specific spine surgeries, the associations between preoperative factors and the need for blood transfusion must be elucidated in a large, national patient sample.…”

Cost-Effectiveness of Cell Saver in Short-segment Lumbar Laminectomy and Fusion (≤3 Levels)

“…identifi ed body mass index, number of levels fused, and interbody fusion as predictors for the use of Cell Saver, which agrees with our fi ndings here with the exception of interbody fusion. 11 The increased surgery duration for Cell Saver patients can be attributed to the fact that this cohort had a greater number of revision surgeries and tended to involve more vertebral levels than the non-Cell Saver group. We found no statistically signifi cant difference in the proportion of patients in the 2 cohorts who had at least 1 intraoperative ABT.…”

“…The rate of Cell Saver utilization was only 17% in our cohort, which is signifi cantly lower than rates reported in other studies. [11][12][13][14] Few strict guidelines for the use of IOCS exist, but several accepted indications include high volume of expected blood loss, patient preference or religious objections, or lack of compatible allogeneic blood. 9 , 18 The Cell Saver cohort had several key differences in demographic characteristics and comorbidities.…”

“…[8][9][10] Studies of Cell Saver in lumbar spine surgery, however, are few in number and have produced mixed results regarding its ability to reduce the need for intraor postoperative ABT. [11][12][13][14][15] Even fewer studies have addressed transfusion costs or cost-effectiveness. 14 , 16 The aim of this study is to assess the cost-effectiveness of Cell Saver IOCS in the setting of lumbar decompression laminectomy and fusion of 3 or fewer levels.…”
