Charlson comorbidity index is predictive of postoperative clinical outcome after single-level posterior lumbar interbody fusion surgery

Abstract Background In several previous studies, Charlson comorbidity index (CCI) score was associated with postoperative complications, mortality, and re-admission. There are few reports about the influence of CCI on clinical outcome. The purpose this study to investigate comorbidities as calculated outcomes after PLIF. Methods Three hundred sixty-six patients who underwent an elective primary single-level PLIF were included. Postoperative outcome evaluated Japanese Orthopaedic Association lumbar (JOA score). correlation coefficient between improvement in JOA investigated. Patients divided into three groups according their (0, 1, 2+). rate, length stay (LOS), direct cost compared each group. complications also Results a weak negative relationship rate ( r = − 0.20). LOS had almost no score. group 0 1 significantly higher than 2+. different 14 complications. Adverse equivalently distributed group, not number comorbidities. Conclusions A leads poor recovery two or more without However, did increased costs. surgeon must take consideration patient’s when planning surgical intervention order achieve good
