Access Vascular’s HydroMid Midline Catheter Shows Increased Dwell Times in Retrospective Data Review

July 12, 2022—Access Vascular, Inc. (AVI) announced initial findings from a retrospective review of patient records that demonstrates an increase in dwell times compared to other commercially available devices and no complications when using the company’s consistently hydrophilic materials for HydroMid midline catheters.

AVI’s hydrophilic biomaterial catheters mimic the body’s chemistry to significantly reduce the most common and costly complications associated with vascular access procedures. Given the high utilization and complication rates of standard catheters, the use of AVI devices may meaningfully improve patient outcomes. The company announced FDA clearance of the HydroMid device in February 2021.

According to the company, the 3-month retrospective evaluation of 29 HydroMid catheters at a long-term, acute care hospital in the United States was conducted in early 2022. AVI’s biomaterial-based catheters were found to have an average dwell time of 15.8 days. Additionally, there were no incidences of phlebitis, occlusion, deep vein thrombosis (DVT), or blood stream infections. The company noted, by contrast, studies that have shown that traditional, polyurethane-based midline catheters have a median dwell time of only 6 days and an incidence of phlebitis of up to 35%, exhibit up to 7% rate of DVT, a 0.88% incidence of catheter-related bloodstream infection, and an average occlusion rate of 22%.

“Midlines are an essential vascular access tool, but clinicians have been hampered for years by polyurethane-based catheters that must continually be replaced or that lead to unnecessary and frequent complications,” commented AVI’s CEO James Biggins. “These new data show that choosing the right catheter can make all the difference, giving clinicians the trust and competence they desire from their vascular access devices. We are confident that new, ongoing studies will demonstrate even longer dwell times for AVI’s biomaterial-based catheters.”
