Comparison of readmission rates from this study with that of the peer-reviewed literature on outpatient ACDF.
Number of outpatient ACDF patients Readmission rate Silvers et al., 1996 50 NR Stieber et al., 2005 30 0% Villavicencio et al., 2007 103 1.9% Erickson et al., 2007 58 0% Liu et al., 2009 45 0% Garringer et al., 2010 645 NR Trahan et al., 2011 59 1.7% Lied et al., 2013 96 1.0% Tally et al., 2013 119 0% McGirt et al., 2015 1,168 NR* Adamson et al., 2016 1,000 2.2% Present study 1,528 5.4% NR = Not reported.
↵* = Did not specifically report readmission rate; rate of “major morbidity” (surgical site infection, new neurological deficit, stroke, reintubation, deep vein thrombosis/pulmonary embolism, myocardial infarction, postoperative hematoma, return to operating room within 30 days) was 0.94%.
