Purpose

The purpose of this study is to compare the average cost per hospitalization of inpatients who have undergone vertebral augmentation in the fluoroscopy suite compared to those who had the procedure in the operating room.

Methods & Materials

Institutional review board approval was obtained for the study. 89 patients were retrospectively identified using billing data between April of 2008 and September of 2010 who were admitted to our institution with a diagnosis of vertebral fracture (ICD-9 codes 733.13, 805.2, & 805.4) and underwent vertebral augmentation during their hospitalization (ICD-9 codes 81.65 & 81.66). At our institution, one interventional Neuroradiologist performs vertebral augmentation in the fluoroscopy suite. The remaining credentialed physicians perform these procedures in the operating room. The location of the procedure was assumed based on the surgeon of record. The two cohorts were compared based on length of stay, total cost of the admission, and daily cost of the admission. A one-tailed T-Test was used to compare the findings.

Results

39 patients were identified who had vertebral augmentation performed in the fluoroscopy suite during their hospitalization with an average of 81.7 years. 70% were female. 25 patients were identified who had vertebral augmentation performed in the operating room during their hospitalization with an average age of 80.7 years. 65% were female. The average length of stay was not statistically different between the two groups. The average total cost per hospitalization was $26,074 in the group who had vertebral augmentation in the fluoroscopy suite compared to $32,078 for the group who had vertebral augmentation in the operating room. The average cost per day was $2,041 compared to $2,452. These findings were statistically significant.

Conclusion

Our findings suggest that vertebral augmentation performed on the inpatient population in the fluoroscopy suite is significantly cheaper than when it is performed in the operating room, without affecting length of stay for the hospitalization.
