OBJECTIVES: The aim of this study was to determine in-hospital mortality, post-surgical thromboembolic events, and health care costs associated with the placement of prophylactic inferior vena cava filters (IVCFs) prior to bariatric surgery.
BACKGROUND: The role of prophylactic IVCFs prior to bariatric surgery is controversial, and the nationwide clinical outcomes associated with this practice are unknown.
METHODS: This observational study used the National Inpatient Sample database to identify obese patients who underwent bariatric surgery from January 2005 to September 2015. Using propensity score matching, outcomes associated with patients receiving prophylactic IVCFs prior to their bariatric surgery were compared with those among patients who did not receive IVCFs.
RESULTS: A total of 258,480 patients underwent bariatric surgery, of whom 1,047 (0.41%) had prophylactic IVCFs implanted. Patients with prophylactic IVCFs compared with those without IVCFs had a significantly higher rate of the combined endpoint of in-hospital mortality or pulmonary embolism (1.4% vs. 0.4%; odds ratio: 3.75; 95% confidence interval [CI]: 1.25 to 11.30; p = 0.019). Additionally, prophylactic IVCFs were associated with higher rates of lower extremity or caval deep vein thrombosis (1.8% vs. 0.3%; odds ratio: 6.33; 95% CI: 1.87 to 21.4; p < 0.01), length of stay (median 3 days vs. 2 days; p < 0.01), and hospital charges (median $63,000 vs. $37,000; p < 0.01).
CONCLUSIONS: In this nationwide observational study, prophylactic IVCF implantation prior to bariatric surgery was associated with worse clinical outcomes and increased health care resource utilization.
