摘要
Background: To determine recent inferior vena cava filter (IVCF) retrieval volumes and rates in the Medicare population. Methods: The summary Medicare claims data were searched for the years 2012 to 2016 to identify the frequency of IVCF placements and retrievals. The new Healthcare Common Procedure Coding System code for filter retrieval introduced in 2012, 37193, was used to track filter retrievals. Trends in number of IVCF placements and retrievals over the study period were evaluated, both of which were further stratified by physician specialty and site of service. Aggregate and compound annual growth rates for retrievals were also computed. Results: A total of 255,034 filters were placed over the study period, with the filter placement volume declining from 61,889 in 2012 to 38,095 in 2016. Filter retrievals, however, increased from 4,327 in 2012 to 8,405 in 2016. The net filter retrieval rate per annual filters placed increased from 6,9% in 2012 to 22.1% in 2016, yielding an average filter retrieval rate and compound annual growth rate of 11.6% and 18.1% respectively. Radiologists placed and retrieved the majority of filters (60.4% placed, 63.5% retrieved) compared with nonradiologists. The inpatient setting was the dominant site for filter placement compared with the outpatient setting for filter retrieval across all years and specialties. Conclusions: Since introduction of the unique Healthcare Common Procedure Coding System code for IVCF retrieval in 2012, IVCF placements in the Medicare population have been declining and net retrieval rates have risen. Radiologists continue to place and retrieve the majority of filters.
