Abstract

Background context: The frequency of anterior cervical fusion (ACF) surgery and total hospital costs in spine surgery have substantially increased in the last several years. Purpose: To determine which patient comorbidities are associated with increased total hospital costs after elective one- or two-level ACFs. Study design/Setting: Retrospective cohort analysis. Patient sample: Individuals who have undergone elective one- or two-level ACFs at our single institution. The total number of patients amounted to 1,082. Outcome measures: Total hospital costs during single admission. Methods: Multivariate linear regression models were used to analyze independent effects of preoperative patient characteristics on total hospital costs. Univariate analysis was used to examine association of these characteristics on operative time, length of hospital stay (LOS), and complications. Results: Age, obesity, and diabetes were independently associated with increased average hospital costs of $1,404 (95% confidence interval [CI], $857-$1,951; p<.001), $681 (95% CI, $285-$1,076; p=.001), and $1,877 (95% CI, $726-$3,072; p=.001), respectively. Age was associated with increased LOS (p<.001) and complications (p<.001) but not operative time (p=.431). Diabetes was associated with increased LOS (p<.001) and complications (p=.042) but not operative time (p=.234). Obesity was not associated with increased LOS (p=.164), complications (p=.890), or operative time (p=.067). Conclusions: This study highlights the patient comorbidities associated with increased hospital costs after one- or two-level ACFs and the potential drivers of these costs.
