Abstract

Purpose: Review of 216 consecutive idiopathic scoliosis (IS) patients undergoing posterior spinal fusion (PSF) demonstrated 94.9% having abnormal lab values, but only 3.9% were referred for further evaluation. A limited set of preoperative laboratory testing costing $234/patient, and thorough, adjunct review of patient/family history could identify potentially significant comorbidities preoperatively in this study. A savings of $1556/patient from current laboratory testing was identified. Methods: The laboratory tests routinely obtained preoperatively were investigated: abnormal preoperative laboratory outcomes were identified and further documented if additional action was taken defined as a referral to another medical provider, performance of additional lab testing or counseling, or if there was alteration of the surgical plan. Results: Overall, 94.9% (n = 205) of patients had one or more abnormal pre-operative lab values. Further actions occurred in 11.7% (n = 24) of all abnormal lab values with 3.9% (n = 8) of these being referred to other healthcare providers. Sixteen abnormal lab values underwent further testing or treatment: 11 nicotine tests, two UCx, one UA, one PT/PTT, and one bovine gelatin RAST. Eight abnormal tests prompted referral to another provider: three CBC, three platelet function tests, one UCx, and one UA. Based on these data, standard preoperative Hgb/Hct, platelet function tests, and bovine RAST (If the surgical plan involves use of bovine gelatin products) appear to be adequate to identify potential significant comorbidities in IS patients undergoing PSF for only $234/patient, a cost savings of $1556/patient from current protocol. Conclusion: Based on this study of 216 patients, a limited preoperative laboratory testing and thorough, adjunct review of patient/family history appears to be adequate to identify potential comorbidities preoperatively in this study. Level of evidence: II.
