This study states that An exponential increase in number of office-based laboratories (OBLs) has occurred in the United States, since the Center for Medicare and Medicaid Services increased reimbursement for outpatient vascular interventions in 2008. This dramatic shift to office-based procedures directed to the objective to assess safety of vascular procedures in OBLs.

A retrospective analysis was performed to include all procedures performed over a 4-year period at an accredited OBL. The procedures were categorized into groups for analysis; group I, venous procedures; group II, arterial; group III, arteriovenous; and group IV, inferior vena cava filter placement procedures. Local anesthesia, analgesics, and conscious sedation were used in all interventions, individualized to the patient and procedure performed. Arterial closures devices were used in all arterial interventions. Patient selection for procedure at OBL was highly selective to include only patients with low/moderate procedural risk.

Nearly 6201 procedures were performed in 2779 patients from 2011 to 2015. The mean age of the study population was 66.5 ± 13.31 years. There were 1852 females (67%) and 928 males (33%).
