Purpose
To evaluate inferior vena cava filter (IVCF) placement and retrieval trends over a 4-year period at a single academic institution to determine if changes in clinical guidelines have impacted utilization.
Materials & Methods
Electronic medical records and billing databases were reviewed to collect data on IVCF placements and retrievals from January 1, 2010 to December 31, 2013. Information ascertained included patient age/gender, date of filter placement/retrieval, indication for placement/retrieval, and anticoagulation status before filter placement. Absolute numbers and percentages of IVCF placement and retrieval were described. Comparisons of IVCF placement and retrieval rates from 2010 to 2013 were performed by Chi-square test using contingency tables.
Results
There were 620 IVCF placements and 279 retrievals. There was a steady 60% decline in IVCF placements with 235 in 2010 to 95 in 2013. The largest decline was seen for prophylactic indications from 52% in 2010 to 10% in 2013. Trauma was the largest prophylactic indication consisting of 29% of placements in 2010 declining to only 6% in 2013. There was no significant change in filter retrieval rates (p=0.19).
Conclusions
From January 1, 2010 to December 31, 2013, there was an overall declining trend in IVCF placements with the largest decline seen in the prophylaxis group and no significant change in IVCF retrieval rates over the 4-year period.
