Preoperative anemia does not predict complications after single-level lumbar fusion: a propensity score-matched multicenter study.

摘要: Study Design. Multicenter retrospective cohort study. Objective. To estimate the impact of preoperative anemia on 30-day complications in patients undergoing single-level lumbar fusion. Summary Background Data. Anemia has been widely implicated as a risk factor various surgical procedures including elective spine surgery. No large-scale study performed to examine this relationship fusion Methods. The American College Surgeons National Surgical Quality Improvement Program database was retrospectively reviewed identify all who underwent during 2006 2011. A propensity score–matching algorithm used match scores anemic with that nonanemic patients. Multivariate logistic regression analysis unadjusted and score–matched cohorts effect postoperative complication rates length hospital stay. Results. total 2960 met inclusion criteria. procedure yielded 491 pairs well-matched multivariate population found carry no significant association any analyzed, overall complications, medical reoperation, mortality, or Conclusion. For fusion, is not independently associated increased Further studies are needed validate other procedures. Level Evidence: 3
