RESUMO

OBJECTIVE: Superficial venous incompetence (SVI) is a common disease that causes significant quality of life (QoL) impairment. There is a need for more health economic evaluations of SVI treatment. The aim of this study was to perform a cost effectiveness analysis in patients with great saphenous vein (GSV) incompetence comparing radiofrequency ablation (RFA), high ligation and stripping (HL/S), and no treatment or conservative treatment with one year follow up. METHODS: Randomised controlled trial economic analysis from an ongoing trial; 143 patients (156 limbs) with GSV incompetence (CEAP clinical class 2 - 6) were included. Treatment was performed with RFA or HL/S. Follow up was performed up to one year using duplex ultrasound, revised venous clinical severity score (r-VCSS), Aberdeen Varicose Vein Questionnaire (AVVQ), and EuroQol-5D-3L (EQ-5D-3L). RESULTS: Seventy-eight limbs were treated with RFA and HL/S respectively. No treatment or conservative treatment was assumed to have zero in treatment cost and no treatment benefit. In the RFA group, one limb had reflux in the GSV after one month and three limbs after one year. In HL/S, two limbs had remaining reflux in the treated area at one month and one year. Both disease severity (r-VCSS, p = .004) and QoL (AVVQ, p = .021 and EQ-5D-3L, p = .028) were significantly improved over time. The QALY gain was 0.21 for RFA and 0.17 for HL/S. The cost per patient was calculated as €1 292 for RFA and €2 303 for HL/S. The cost per QALY (compared with no treatment or conservative treatment) was €6 155 for RFA and €13 549 for HL/S. With added cost for days absent from work the cost per QALY was €7 358 for RFA and €24 197 for HL/S. The cost per QALY for both methods was well below the threshold suggested by Swedish National Board of Health. CONCLUSION: RFA is more cost effective than HL/S and no treatment or conservative treatment at one year follow up.

RESUMO

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.

RESUMO

OBJECTIVE: Chronic venous disease (CVD) is accompanied by a spectrum of skin changes. The aim of this study was to assess skin changes in CVD in different classes of the classifications such as the Clinical-Etiology-Anatomy-Pathophysiology (CEAP) classification using ultrasound (US). METHODS: This study was conducted from July 2020 to July 2021 after obtaining approval from Institutional Ethical Committee. Patients with chronic venous insufficiency were enrolled after taking informed consent. Assessment of cutaneous layer (CL), subcutaneous layer (SCL), dermo-hypodermal junction (D-HJ), and other significant US findings were noted. RESULTS: Ninety-eight limbs were evaluated. Most common skin finding was dermal edema in 59 (60.2%) legs. Other findings included infiltrates, CL thickening, hyper echogenicity and thickening of SCL, anechoic lacunae, disappearance of D-HJ, and epidermal loss or change in thickness of epidermis. Notably, US detected dermal edema in 15 and infiltrates in five C2 legs (normal on inspection). CONCLUSION: US evaluation of skin changes adds insight to clinical assessment and may reveal skin changes in legs affected with CVD that may appear normal on clinical examination.

RESUMO

BACKGROUND: In 2021, the Centers for Medicare & Medicaid Services (CMS) mandated that every hospital create a publicly available webtool for pricing various medical services in an effort to give patients transparency in regard to their health care expenses and allow patients to "shop around" to receive the care most fitting their budget. Our objective is to investigate the utility this mandate provides for vascular surgery patients. METHODS: Standardized searches were performed to find patient cost calculators for Newsweek's Top 50 Hospitals in the United States. If the webtool was found, a list of standardized searches were performed to investigate whether the tool listed prices for the following vascular procedures: Arteriovenous fistula (AVF), varicose vein procedures, and Endovascular Aneurysm Repair (EVAR). RESULTS: Of the 50 hospitals included, all had an easily accessible web-based cost estimator tool. The average time to find the cost estimator was 33.27 sec. Of these 50 hospitals, 10% provided cost information on AVF surgery, 12% provided cost information on varicose vein procedures, and 0% provided information on EVAR. There was no difference in the hospital's likelihood to report a price based on region of the United States. Average preinsurance price for AVF surgery was $11,933.61 and $22,191 for vein procedures. CONCLUSIONS: In conclusion, despite good adherence to the CMS mandate requiring a publicly available pricing tool, these tools provide little to no information for vascular surgery patients. Overall, this discrepancy places vascular surgery patients at a significant disadvantage. As such, vascular patients do not have access to the knowledge necessary to financially prepare for surgery, and furthermore, they are not afforded the luxury to choose where to have procedures performed based on price variability. Hopefully this research will encourage hospitals to broaden the scope of their cost calculators to allow it to benefit all patients.

RESUMO

INTRODUCTION: The primary aim is to estimate the cost-effectiveness of transjugular intrahepatic portosystemic stent shunt (TIPSS) in two indications from a Spanish perspective. Firstly, as pre-emptive treatment for patients with acute variceal bleeding (indication 1) compared with endoscopic band ligation plus drug therapy. Secondly, to treat refractory ascites (indication 2) compared with large volume paracentesis. METHODS: A two-state (alive and dead) Markov model was developed to capture the costs and health impact for the two indications over a 2-year time horizon with monthly cycles. In the alive state, patients could experience adverse event(s), associated with costs and disutility, such as recurrent variceal bleeding, ascites, and hepatic encephalopathy. Discount rates of 3% for utilities and costs and a cost-effectiveness threshold of €25,000 per QALY were applied. RESULTS: In the base case analysis, TIPSS was estimated to be cost-effective as a pre-emptive treatment for indication 1 (incremental cost and QALYs of - €230 and 0.211, respectively). TIPSS also remained cost-effective (€16,819/QALY) in a conservative scenario analysis, conducted with an alternate source for clinical parameters. The key drivers of the outcomes were survival for the comparator arm, mean band ligation outpatient procedures, and TIPSS treatment costs. TIPSS was estimated to dominate the comparator for indication 2 (incremental cost and QALYs of - €25,687 and 0.531, respectively). The key drivers of the outcomes were monthly paracentesis sessions and cost per inpatient stay for those undergoing paracentesis. CONCLUSIONS: TIPSS is likely to be a cost-effective and a cost-saving treatment in patients with cirrhosis in indications 1 and 2, compared with standard treatments. The analyses estimate clinical benefits along with reduced healthcare costs from avoided downstream resource consumption.

RESUMO

BACKGROUND AND AIM: Hepatic decompensation is a major complication of liver cirrhosis. We validated the predictive performance of the newly proposed CHESS-ALARM model to predict hepatic decompensation in patients with hepatitis B virus (HBV)-related cirrhosis and compared it with other transient elastography (TE)-based models such as liver stiffness-spleen size-to-platelet (LSPS), portal hypertension (PH), varices risk scores, albumin-bilirubin (ALBI), and albumin-bilirubin-fibrosis-4 (ALBI-FIB-4). METHODS: Four hundred eighty-two patients with HBV-related liver cirrhosis between 2006 and 2014 were recruited. Liver cirrhosis was clinically or morphologically defined. The predictive performance of the models was assessed using a time-dependent area under the curve (tAUC). RESULTS: During the study period, 48 patients (10.0%) developed hepatic decompensation (median 93 months). The 1-year predictive performance of the LSPS model (tAUC = 0.8405) was higher than those of the PH model (tAUC = 0.8255), ALBI-FIB-4 (tAUC = 0.8168), ALBI (tAUC = 0.8153), CHESS-ALARM (tAUC = 0.8090), and variceal risk score (tAUC = 0.7990). The 3-year predictive performance of the LSPS model (tAUC = 0.8673) was higher than those of the PH risk score (tAUC = 0.8670), CHESS-ALARM (tAUC = 0.8329), variceal risk score (tAUC = 0.8290), ALBI-FIB-4 (tAUC = 0.7730), and ALBI (tAUC = 0.7451). The 5-year predictive performance of the PH risk score (tAUC = 0.8521) was higher than those of the LSPS (tAUC = 0.8465), varices risk score (tAUC = 0.8261), CHESS-ALARM (tAUC = 0.7971), ALBI-FIB-4 (tAUC = 0.7743), and ALBI (tAUC = 0.7541). However, there was no significant difference in the predictive performance among all models at 1, 3, and 5 years (P > 0.05). CONCLUSIONS: The CHESS-ALARM score was able to reliably predict hepatic decompensation in patients with HBV-related liver cirrhosis and showed similar performance to the LSPS, PH, varices risk scores, ALBI, and ALBI-FIB-4.

RESUMO

OBJECTIVES: Few studies compared both ultrasound and histological approaches for the same series of patients with chronic venous disease (CVD). We aimed to assess the diagnostic performances of duplex ultrasound assessment (US) of Vein Wall Thickness (VWT) among patients with CVD. METHODS: 38 adults with primary varicose veins having undergone Great Saphenous Vein thermal ablation with phlebectomy, and agreeing to biopsy of the Posterior Accessory Great Saphenous Vein (PASV) were consecutively included in a two-center prospective study. VWT assessment of the PASV was performed using both US, and microscope examination. High values for microscope-assessed VWT were defined at > 0.5 mm. RESULTS: The mean age was 53.0 ± 13.1 years, 71% were women. Maximization of US performances was obtained with a threshold of 0.6 mm: Sensitivity (Se) = 92.9%, Specificity (Sp) = 91.7%, positive (86.7%) and negative predictive value (NPV) (95.7%), positive (11.1) and negative likelihood ratio (NLR) (0.07). CONCLUSIONS: US assessment of VWT could be a non-invasive tool for diagnosis and follow-up in CVD, and an interesting in vivo parameter complementing diameter and reflux measures, with a view to optimizing treatment. It could help to determine i) the energy level necessary in case of endovenous laser ablation, and ii) the sclerosing agent concentration in case of chemical ablation.

RESUMO

OBJECTIVES: Landmark studies published near the turn of the 21st century found an implementation gap concerning the effect of evidenced-based findings on clinical practice. The current study examines the uptake of six trials that produced actionable findings to describe the effects of evidence on practice and the reasons for those effects. DESIGN: A sequential, explanatory mixed methods study was conducted. First, a quantitative study assessed whether actionable findings from large, publicly funded elective surgical trials influenced practice. Subsequently, qualitative interviews were conducted to explain the quantitative findings. SETTING: Changes in NHS-funded practice were tracked across hospitals in England. Interviews were conducted online. DATA AND PARTICIPANTS: The six surgical trials were funded and published by England's National Institute for Health Research's Health Technology Assessment programme between 2006 and 2015. Quantitative time series analyses used data about the frequencies or proportions of relevant surgical procedures conducted in England between 2001 and 2020. Subsequently, qualitative interviews were conducted with 25 participants including study authors, surgeons and other healthcare staff in the supply chain. Transcripts were coded to identify major temporal events and Consolidated Framework for Implementation Research (CFIR) domains/constructs that could influence implementation. Findings were synthesised by clinical area. RESULTS: The quantitative analyses reveal that practice changed in accordance with findings for three trials. In one trial (percutaneous vs nasogastric tube feed after stroke), the change took a decade to occur. In another (patella resurfacing), change anticipated the trial findings. In the third (abdominal aortic aneurysm repair), changes tracked the evolving evidence base. In the remaining trials (two about varicose veins and one about gastric reflux), practice did not change in line with findings. For varicose veins, the results were superseded by a further trial. For gastric reflux, surgical referrals declined as medical treatment increased. The exploratory qualitative analysis informed by CFIR found that evidence from sources apart from the trial in question was mentioned as a reason for non-adoption in the three trials where evidence did not affect practice and in the trial where uptake was delayed. There were no other consistent patterns in the qualitative data. CONCLUSION: While practice does not always change in the direction indicated by clinical trials, our results suggest that individuals, official committees and professional societies do assimilate trial evidence. Decision-makers seem to respond to the totality of evidence such that there are often plausible reasons for not adopting the evidence of any one trial in isolation.

RESUMO

PURPOSE OF REVIEW: In 2015, as a consequence of the high development in noninvasive tests, Baveno VI consensus recommended for the first time the use of a prediction rule (liver stiffness <20kPa and platelet count > 150000) to identify patients at low risk of having varices and that could circumvent endoscopy. These became known as the Baveno VI criteria. We review here the data validating Baveno VI criteria and we discuss the attempts of expanding these criteria. RECENT FINDINGS: We report 28 studies assessing the performance of Baveno VI criteria showing a pooled 99% negative predictive value for ruling out high-risk varices. Performance is not affected by the cause of cirrhosis. Different attempts at expanding these criteria show suboptimal performance. Nonelastography-based criteria require further validation. SUMMARY: Baveno VI criteria can be safely used to avoid endoscopy in a substantial proportion of patients with compensated cirrhosis. The progressive change in approach to the management of compensated cirrhosis, progressively focusing on treating portal hypertension with beta-blockers independently of the presence of varices, might render these criteria less relevant.

RESUMO

PURPOSE: We assessed venous thromboembolism (VTE) and associated risk factors following artificial urinary sphincter (AUS) and inflatable penile prosthesis (IPP) surgery. MATERIALS AND METHODS: Using IBM® MarketScan, a commercial claims database, patients undergoing AUS and IPP surgery were identified using CPT® and ICD (International Classification of Diseases)-10 procedure codes between 2008 and 2017. ICD-9 and -10 codes were used to identify health care visits associated with lower extremity deep vein thrombosis (DVT) and pulmonary embolism (PE) within 90 days of surgery. Covariates were assessed using a multivariable model to determine association with outcome of DVT and/or PE. RESULTS: A total of 21,413 men underwent AUS (4,870) or IPP (16,543) surgery between 2008 and 2017 with a median age of 62 years and 68 years, respectively. DVT and PE events following AUS and IPP surgery occurred in 1.54% and 1.04%, respectively. A history of varicose veins (HR 2.76; 95% CI 1.11-6.79), prior history of DVT (HR 13.65; 95% CI 7.4-25.19), or PE (HR 7.65; 95% CI 4.01-14.6) in those undergoing AUS surgery was highly associated with development of postoperative VTE. Likewise, prior history of DVT (HR 12.6; 95% CI 7.99-19.93) and PE (HR 8.9; 95% CI 5.6-14.13) was strongly associated with a VTE event following IPP surgery. CONCLUSIONS: In a large cohort of men undergoing AUS and IPP surgery, 1.54% and 1.04% of men experienced a VTE event within 90 days of surgery, respectively. Prior history of varicose veins, DVT, and PE was associated with an increased likelihood of developing a postoperative DVT or PE.

RESUMO

BACKGROUND: Acoustic structure quantification (ASQ) has been applied to evaluate liver histologic changes by analyzing the speckle pattern seen on B-mode ultrasound. We aimed to assess the severity of portal hypertension (PHT) through hepatic ultrasonography. METHODS: Sixty patients diagnosed with PHT and underwent surgical treatment with portosystemic shunts were enrolled. Portal pressure (PP) was measured intraoperatively. Patients were divided into subgroups according to the severity of gastroesophageal varices and Child-Pugh class. Three difference ratio (Cm2) values on ASQ histogram mode were analyzed for their relationships with PP, degree of gastroesophageal varices and Child-Pugh liver function. Thirty healthy volunteers matched with the patients for gender and age were enrolled as controls. Comparisons among groups and correlation of the parameters with PP were analyzed. Area under the receive operating characteristic curve was used to evaluate the predicting value of ASQ parameters. RESULTS: In the patients, the ASQ parameters peak Cm2 (Cm2max), mean Cm2 (Cm2mean) and the highest occurred Cm2 value of the obtained red curve (RmaxCm2) were all greatly increased (P < 0.0001, P < 0.0001, P = 0.027). Multiple comparisons indicated that, regardless of Child-Pugh class and degree of gastroesophageal varices, the patients had significantly increased Cm2max and Cm2mean compared with the controls (all P < 0.0001). No differences among subgroups were observed. Cm2max was significantly statistically correlated with PP (r = 0.3505, P < 0.01), degree of varices (r = 0.4998, P < 0.0001). Youden's index for Cm2max with a cut-off value of 140.3 for predicting the presence of PHT, gastroesophageal varices and liver function equal to or worse than Child-Pugh class B were 0.8, 0.91 and 0.84, respectively. CONCLUSIONS: ASQ analysis of ultrasonographic images may have a role in the evaluation of the severity of PHT by detecting liver histologic changes in the speckle pattern caused by cirrhosis.

RESUMO

Quality of life (QoL) in patients with chronic venous disorders has a central role to decide the correct treatment approach. In particular, in case of mini-invasive therapy, such as endovenous radiofrequency ablation (RFA), the postoperative QoL improvement remains one of the most important outcome to be reached. Despite this, very few data are published on the long-term QoL modifications after RFA. The aim of this brief report is to describe and analyze the role of QoL scales in a population of patients treated with RFA of the great saphenous vein and phlebectomies, highlighting results in short- and long-term follow-up period, and differences between recanalized and non-recanalized patients.

RESUMO

BACKGROUND: Chronic venous disease is a frequent vascular condition. International societies have recommended the use of health-related quality of life (HRQoL) instruments in the assessment of patients with vascular diseases. Thus, the Freiburg Life Quality Assessment for chronic venous disease, 10-item questionnaire (FLQA-VS-10) was developed. The aim of the present study was to validate the FLQA-VS-10 in a prospective study. METHODS: We recruited 100 patients with recurrent varicosis or incomplete or complete venous insufficiency undergoing interventional vein treatment (high ligation of the great or small saphenous vein or endovenous ablation therapy). These patients completed the FLQA-VS-10 and instruments assessing convergent validation criteria at four points: preoperatively (T1), postoperatively (T2) and twice 3 years later with a 1-week interval (T3 and T4). RESULTS: The mean age was 56.0 ± 13.7 years, and 66.0% were women. The patients had presented with recurrent varicosis of the saphenofemoral junction (28.0%), recurrent varicosis of the saphenopopliteal junction (1.0%), incomplete or complete insufficiency of the great saphenous vein (69.0%), or complete insufficiency of the small saphenous vein (2.0%). The items showed few missing values. The FLQA-VS-10 global score showed no ceiling effect (patients reporting the highest possible impairments in HRQoL) but did show a floor effect (patients reporting the lowest possible impairments in HRQoL), which was highest at the postoperative assessments. The internal consistency of the global score was high at all measurement points. A convergent validity and responsiveness analysis revealed that the FLQA-VS-10 correlated in the expected direction with the convergent instruments, including the Freiburg Life Quality Assessment for venous diseases (venous disease-specific HRQoL) and the five-level EQ-5D (generic HRQoL). Data from T3 and T4 revealed high test-retest reliability (intraclass correlation, 0.92). Overall, the patients stated that the FLQA-VS-10 was comprehensible, comprehensive, and easy to complete. CONCLUSIONS: Our data suggest that the FLQA-VS-10 is a reliable, valid, responsive, and feasible HRQoL questionnaire for patients with chronic venous diseases. This questionnaire can serve as short and easy-to-use instrument to assess patient-reported outcomes in the treatment of these patients.

RESUMO

BACKGROUND: Coexistence of dilating venous diseases in different vascular territories has raised the idea that they have similar vascular wall abnormality in their evolutionary process. Accordingly, we aimed to evaluate venous leg symptoms in patients with hemorrhoidal disease (HD) by means of VEINES-Sym questionnaire. MATERIALS AND METHODS: The study involved 249 consecutive patients who underwent colonoscopy and met the inclusion criteria. Presence and grading of HD were made according to Goligher's classification. All patients were examined for the existing of varicose vein and classified in respect of CEAP classification. All participants were requested to answer the VEINES-Sym questionnaire. RESULTS: There was not statistically significant differences between the patients without HD (grade 0 or I) and with HD (Grade II or III) in respect to clinical characteristics except female predominance in hemorrhoid group (p = 0.07). Scores of heavy legs, swelling, burning sensation, restless leg, throbbing, tingling, and total VEINES score were significantly lower (ie: worse) in hemorrhoid group. Logistic regression analysis revealed that female gender and total VEINES score were independently associated with HD (OR: 2.03, 95% CI: 1.17-3.52, p = 0.01; OR: 0.96, 95% CI: 0.92-0.99, p = 0.02, respectively). Among all venous leg symptoms, severity of heavy legs, night cramps, swelling and aching were significantly correlated with the grades of HD. CONCLUSION: We have shown significant association between the HD and venous leg symptoms reflected by total VEINES score and significant correlation between the HD grade and venous leg symptoms severity including heavy legs, swelling, night cramps and aching legs.

RESUMO

OBJECTIVE: To analyze the effectiveness and cost effectiveness of technologies for treatment of varicose veins over 5 years-conservative care, surgery (high ligation and stripping), ultrasound-guided foam sclerotherapy (UGFS), endovenous laser ablation (EVLA), and radiofrequency ablation (RFA), mechanochemical ablation (MOCA), and cyanoacrylate glue occlusion (CAE). METHODS: A systematic review was updated and used to construct a Markov decision model. Outcomes were reintervention on the truncal vein, retreatment of residual varicosities and quality-adjusted life years (QALY) and costs over 5 years. RESULTS: UGFS has a significantly greater reintervention rate than other procedures; there is no significant difference between the other procedures. The cost per QALY of EVLA vs UGFS in our base-case model is £16,966 ($23,700) per QALY, which is considered cost effective in the UK. RFA, MOCA, and CAE have greater procedure costs than EVLA with no evidence of greater benefit for patients. CONCLUSIONS: EVLA is the most cost-effective therapeutic option, with RFA a close second, in adult patients requiring treatment in the upper leg for incompetence of the GSV. MOCA, UGFS, CAE, conservative care, and high ligation and stripping are not cost effective at current prices in the UK National Health Service. MOCA and CAE seem to be promising, but further evidence on the effectiveness, reinterventions, and health-related quality of life is needed, as well as how cost effectiveness may vary across settings and reimbursement systems.

RESUMO

BACKGROUND: Disease of the venous system is an underappreciated public health problem. Minimally invasive treatments such as radiofrequency ablation (RFA) or cyanoacrylate adhesive ablation (CAA) have almost entirely replaced surgical stripping (SS) of the great and small saphenous veins. The purpose of the present study was to compare the outcomes at 3 years after SS, RFA, and CAA by assessing the incidence of complications and reinterventions and performing a cost-effectiveness analysis. METHODS: From February 2016 to February 2019, all consecutive patients with symptomatic varicose veins treated at vascular department of two hospitals using SS, RFA, or CAA were included in the present study. The clinical outcomes were measured by quality-adjusted life years (QALYs), complications, and reintervention. A comparison with conservative treatment was also performed. A detailed resource use was recorded for each procedure. All costs were normalized to May 2020 U.S. dollars and euros. Analysis of the data was by the treatment received. All statistical tests were two-sided, and the significance level was set at 5%. Two perspectives of the analysis were considered: the social perspective and that of the Spanish Public Health System. The study period was 3 years. No discount rate was applied. RESULTS: A total of 233 patients were enrolled in the present study: SS, n = 90 (38.6%); RFA, 93 (39.9%); and CAA, n = 50 (21.5%). The number of complications was 11 (12.2%), 3 (3.3%), and 3 (6%) in the SS, RFA, and CAA groups, respectively (P = .06). No patient had required reintervention. The median loss of workdays for the SS, RFA, and CAA group was 15 days (interquartile range [IQR], 10-30 days), 0 days (IQR, 0-6 days), and 0 days (IQR, 0-1 days), respectively (P < .001). The median level of satisfaction for the SS, RFA, and CAA group was 9 (IQR, 8-10), 10 (IQR, 9-10), and 10 (IQR, 9-10), respectively (P < .001). The QALYs was 2.6 years for all three procedures. The median overall cost was €852 (US$926) for SS, €1002 (US$1089) for RFA, and €1228.3 (US$1335) for CAA. The total cost per QALY was €323/QALY (US$351/QALY) for SS, €380/QALY (US$413/QALY) for RFA, and €467/QALY (US$508/QALY) for CAA. The indirect costs were measured by the cost of the workdays lost for each patient and were €1527 (US$1660; IQR, €1018-3054); €0 (IQR, €0-611) for RFA, and €0 (IQR, €0-102) for CAA (P < .001). CONCLUSIONS: All three techniques were cost-effective (procedures with an incremental cost-effectiveness ratio <€30,000/QALY can be recommended). From the Spanish Public Health System perspective, when considering only the health care costs, the most cost-effective technique was SS. From the social perspective, including the opportunity costs of medical leave, CAA was the most cost-effective technique, saving €1600 per patient, a cost that more than compensated for the savings realized from using SS in direct health care costs.

RESUMO

BACKGROUND: Varicose vein surgeries are the most commonly performed vascular procedure to treat the most prevalent vascular disease, chronic venous disease. However, nationwide studies on the epidemiology of varicose vein surgeries are scarce, none in developing countries. Therefore, we designed this study to assess the total number of varicose vein surgeries performed between 2008 and 2019 in the Public Health System, which exclusively insures more than 160 million Brazilians, their trends, costs and mortality rates. METHODS: Public and open data referring to all surgeries to treat chronic venous disease between 2008 and 2019 were extracted from the Brazilian Ministry of Health database. RESULTS: A total of 869,220 surgeries were performed to treat chronic venous disease in Brazilian public hospitals and outpatient clinics, with an average rate of 4.5 surgeries per 10,000 inhabitants per year. Starting in 2015, we observed a slight non-significant downward trend in the total number of procedures. The total amount reimbursed by the government was US$ 232,775,518.11. A total of 49 deaths were reported after varicose vein surgery, corresponding to a mortality rate of 0.0056%. CONCLUSIONS: A total of 869,220 surgeries were performed to treat chronic venous disease over twelve years, with an overall rate of 4.52 procedures per 10,000 population per year. The mortality rate was very low, 0.0056%.
