Purpose: IVC filters are commonly placed to prevent potentially fatal pulmonary emboli, however, these devices can cause serious adverse effects if not retrieved. We sought to evaluate the effect of patient demographics, clinical complexity, preferred language, zip code, and race on IVC retrieval rates.

Materials and Methods: Patients undergoing IVC Filter placement from January 2020-January 2025 were identified and checked for filter retrieval. Income was approximated using zip code derived median household income from the US census. The Charlson comorbidity index (CCI) was calculated for all patients.

Variables were analyzed for difference in retrieval rate using student’s t test (zip derived income, age, CCI, BMI), chi-squared test (non-English language), and binary logistic regression (race). Multivariate logistic regression models were created to assess the independent effect of socioeconomic factors alongside CCI, BMI, age, and sex.

Results: There were 552 IVC filter placements and 137 were retrieved (24.8%). Older age (p< 0.001), higher CCI (p=0.007), male sex (p< 0.001), and lower zip-derived income were associated with lower retrieval rates (p=0.003). White patients had higher rates of retrieval (p=0.036). Age, zip-derived income, CCI, and white race were independent predictors of retrieval in multivariate analysis.

Conclusion: Socioeconomic and demographic factors such as older age, lower-income zip codes, higher CCI, and non-white race are associated with lower IVC filter retrieval rate. The rates between preferred language did not reach the threshold for significance, likely because of limited power to detect small differences between these populations. Clinicians and health equity programs can target these populations to improve IVC retrieval rates.
