Resource Utilization

In the summary years of 2008 to 2011, there were 261,900 hospital discharges or outpatient visits for complications related to spine surgery. These were evenly distributed between men and woman, with an average age in the mid- to late 40s. Health care visits occurred most frequently in the population under age 18 years, and least frequently among persons age 65 years and older.

Treatment and Complications

Superficial infections are frequently managed with oral antibiotics, while deep infections typically require surgical debridement (removal of dead, damaged, or infected tissue) and IV antibiotics. A small percentage of infections may be complicated by large soft tissue defects and compromised host immune systems, requiring extensive and prolonged treatments and surgical procedures.

Cost

In 2011, there were 146,100 hospital discharges for spondylolisthesis reported in the HCUP NIS database. The average length of stay for these patients was 4 days, and tended to trend slightly upwards with age. The mean charges for hospital discharges with a diagnosis of spondylolisthesis was $93,900, which was unexpectedly higher than all other deformity codes evaluated and statistically similar to costs associated with hospital discharges for patients with complications of spine surgery diagnosis.
