A Comparison of Venaseal Versus Radiofrequency Ablation Outcomes Within a Managed Care Organization.

BACKGROUND: Chronic venous insufficiency is a common medical condition that afflicts over 30 million adults in the United States. Treatment and management have changed dramatically over the past 20 years with the introduction of various endovenous therapies, including radiofrequency ablation (RFA) and cyanoacrylate closure using the Venaseal system. In this study, we explore a direct comparison of outcomes between RFA and VenaSeal conducted by a single surgeon within a managed care organization. METHODS: Between May 2020 and December 2021, there were 87 patients undergoing 97 total procedures who were treated with either VenaSeal (n = 55) or RFA (n = 42), conducted by a single surgeon within a managed care organization. Primary outcomes included successful greater saphenous vein (GSV) closure, postoperative deep vein thrombosis (DVT), embolization, saphenofemoral junction (SFJ) thrombosis, skin reaction (allergic or thrombophlebitis), or procedure-related emergency room (ER) and urgent care (UC) visits. Retrospective chart review was conducted to describe patient demographics, indications for treatment, treatment details (number of access sites and indication for treatment), as well as follow-up adjunctive vein procedures (sclerotherapy and stab phlebectomy). RESULTS: All patients had postprocedural ultrasound (US) performed within 7 days by the operating surgeon and mean overall patient follow-up from index procedure was 12 months; 2 patients were lost to follow-up due to death. All operations utilized intraoperative US, and SFJ thrombosis was not observed in any patient postprocedure. The average age of VenaSeal and RFA groups was 59.05 and 59.51 years, respectively. The average number of access sites during the procedure for VenaSeal and RFA was 1.56 and 1.20, respectively. Of the 55 VenaSeal treatments, 9.1% of patients reported postoperative skin reactions, and 9.1% of patients underwent subsequent stab phlebectomy (22 stabs on average). Of the 42 RFA treatments, 7.1% of RFA patients reported postoperative skin reactions, and 9.5% underwent subsequent stab phlebectomy (36 stabs on average). The percentage of patients who had postoperative UC or emergency department visits related to the procedure in the VenaSeal and RFA groups was 3.6% and 0%, respectively. CONCLUSIONS: Both VenaSeal and RFA demonstrated effective vein closure of the GSV at 12-month follow-up, with VenaSeal demonstrating continued noninferiority to RFA. Based on our data, postoperative skin reactions do not appear to be significantly higher with VenaSeal treatment, as previously reported.

School Attendance Following Receipt of Care From a School-Based Health Center.

PURPOSE: School-based health centers (SBHCs) may mitigate barriers to health care access and improve students' academic outcomes, but few studies test this hypothesis. We examined whether school attendance improved after students received care at an SBHC. METHODS: We conducted a secondary analysis of data from 17 SBHCs affiliated with a single large urban school district and demographic and attendance data from SBHC users (N = 14,030) and nonusers (N = 230,046) from August 2015-February 2020. We examined the percent of full school days present each month for three years before and after students' first SBHC visit and a proxy visit date for SBHC nonusers. Propensity weighted linear regression models tested whether visiting an SBHC was associated with a change in the attendance trajectory compared to a matched sample of SBHC nonusers. RESULTS: Among SBHC users, attendance trajectories declined more steeply prior to their first SBHC visit than after the first visit (preslope -0.71%, postslope -0.05%), whereas SBHC nonusers had a similar attendance trajectory over the entire period (preslope -0.18%, postslope -0.17%), with difference-in-difference 0.65. Changes in trajectories were more pronounced for students with a mental health encounter. Prior to the first SBHC mental health visit, SBHC users displayed a marked decline in monthly attendance (preslope -1.02%). After the first mental health visit, attendance increased (postslope 1.44%), with difference-in-difference 2.33. DISCUSSION: SBHC utilization was associated with improved school attendance over time, particularly for students with a mental health diagnosis. Investing in SBHCs may reduce school absenteeism and support student health.
