Effect of scheduling inferior vena cava filter removal during the placement encounter on filter removal rate

In the present study, we sought to determine whether early pre-emptive scheduling of inferior vena cava filter (IVCF) removal during the preoperative IVCF placement visit would affect the IVCF removal rate.All electronically documented IVCF placements at a single institution were reviewed from April 2015 to July 2019. The baseline characteristics included age, the clinical indications for IVCF placement, inpatient/outpatient status, and type of IVCF placed. Statistical analysis was performed using the χA total of 599 patients (mean age, 68 years; 273 women and 326 men) had undergone technically successful IVCF placement. During the preoperative consent process for placement, 232 patients had been scheduled for IVCF removal within 3 months after placement. However, 367 patients had not been scheduled for removal at the preoperative consent process. The indications for placement included failure of anticoagulation, a contraindication to anticoagulation (eg, bleeding), preoperative prophylaxis, and others. Of the 232 patients scheduled for IVCF removal during preoperative consent for IVCF placement, 103 (44%) had undergone successful IVCF removal (mean interval from placement, 107 ± 100 days). Of the 367 nonscheduled patients, 89 (24%) had undergone successful IVCF removal (mean time, 184 ± 215 days). We found a significant improvement in the IVCF removal rate between the scheduled and nonscheduled patients (P .0001). Three patients (all from the scheduled group) had a clot burden within the IVCF, which meant they were inappropriate for removal. These patients were rescheduled and had eventually undergone uncomplicated removal.Scheduling IVCF removal during the placement encounter significantly increased the IVCF removal rate. This approach could be a viable option for institutions where clinic time and/or resources are limited or unavailable and for patients who have difficulty traveling for clinical evaluations.
