Abstract
BACKGROUND: To determine the impact, if any, of the 2010 FDA safety communication on the rate of inferior vena cava filter (IVCF) placement over time. METHODS: The Nationwide Inpatient Sample was interrogated for the most recent years preceding and after the FDA safety communication-from 2005 to 2014. IVCF placements and associated diagnoses were identified using corresponding International Classification of Diseases, version nine codes. Trends in number of IVCF placement were evaluated in aggregate and by associated diagnoses, both of which were further stratified by hospital geographic cluster, hospital teaching status, and patient demographics. Generalized linear regression models were used to determine statistical significance of trends over time. RESULTS: IVCF placements steadily increased between 2005 and 2010 (100,434 in 2005 versus 129,614 in 2010, growth rate 5.81%). Aggregate IVCF placements subsequently declined between 2010 and 2014 (96,005 in 2014, decline rate -6.48%). IVCF placements peaked in 2010, the year of the FDA advisory. The proportion of filter placements for therapeutic indication of venous thromboembolism increased significantly during the study period (69.8% in 2005 versus 80.4% in 2014, P < .001). Neither trend varied significantly by patient demographics or hospital characteristics. CONCLUSIONS: IVCF placements have declined significantly since 2010, when the FDA advisory was released. The proportion of IVCFs placed in patients with venous thromboembolism, as opposed to prophylactic indications, is increasing.
