Abstract
PURPOSE To compare procedural and long-term costs associated with the use of Balloon-Expandable Covered Stents (BECS) in the management of Aortoiliac Occlusive Disease (AIOD). MATERIALS AND METHODS A cost-consequence model was developed to simulate the intra- and post-operative management of patients with AIOD from the perspective of private health-payers. The study assessed the costs of the LifeStream (BD, Franklin Lakes, New Jersey), iCAST/Advanta V12 (Getinge, Goteborg, Sweden), BeGraft Peripheral (Bentley, Hechingen, Germany), and Viabahn Balloon Expandable (VBX) (W.L. Gore, Flagstaff, Arizona) BECS devices. Device costs were identified from the Australian Prosthesis List, whereas clinical outcomes of BECS were estimated from a systematic review of the literature. Costs were calculated over 24 and 36 month time horizons and reported in US dollars. RESULTS Long-term, per-patient cost of each device at 24 and 36 months was $6253/$6634 for the LifeStream; $6359/$6869 for the iCAST/Advanta V12; $4806 (data available to 24 months) for the BeGraft Peripheral; and $4839/$5046 for the Viabahn VBX, respectively. Most of the cost difference was attributed to the number of stents required per treated limb and frequency of clinically-driven target lesion revascularization events. CONCLUSIONS Best-available clinical evidence and economic modeling demonstrates that the BeGraft Peripheral and Viabahn VBX were of similar cost and the least costly options at 24 months, whereas at 36 months, the lowest cost BECS option for the treatment of AIOD was the Viabahn VBX. CLINICAL IMPACT This analysis supports economically informed decision-making for health-payers managing systems that care for patients with AIOD. Stent length and avoiding reintervention were identified as key areas of cost-saving for future BECS development.

Effects of aerobic and combined training on pain-free walking distance and health-related quality of life in patients with peripheral artery disease: a randomized clinical trial. J Vasc Bras 2023; 22:e20230024. [PMID: 37790896 PMCID: PMC10545230 DOI: 10.1590/1677-5449.202300242] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Accepted: 05/22/2023] [Indexed: 10/05/2023] Open
Abstract
Background Decreased walking ability in patients with peripheral arterial disease is often a clinical problem and limits the quality of life and daily activities of these subjects. physical exercise is important in this scenario, as it improves both the daily walking distance and the ability to withstand intermittent claudication related to the limitations of the peripheral disease. Objectives Our aim was to compare the effects of two types of exercise training (aerobic training and aerobic training combined with resistance exercises) on pain-free walking distance (PFWD) and health-related quality of life (HRQoL) in a sample composed of patients with peripheral artery disease (PAD). Methods Twenty patients with claudication symptoms were randomized to either aerobic control (AC) N= 9, or combined training (CT) N= 8, (24 sixty-minute sessions, twice a week). The total walking distance until onset of pain due to claudication was assessed using the 6-minute walk test and HRQoL was measured using the WHOQOL-bref questionnaire (general and specific domains) at baseline and after training. We used generalized estimating equations (GEE) to assess the differences between groups for the PFWD and HRQoL domains, testing the main group and time effects and their respective interaction effects. P values < 0.05 were considered statistically significant. Results Seventeen patients (mean age 63±9 years; 53% male) completed the study. Both groups experienced improvement in claudication, as reflected by a significant increase in PFWD: AC, 149 m to 299 m (P<0.001); CT, 156 m to 253 m (P<0.001). HRQoL domains also improved similarly in both groups (physical capacity, psychological aspects, and self-reported quality of life; P=0.001, P=0.003, and P=0.011 respectively). Conclusions Both aerobic and combined training similarly improved PFWD and HRQoL in PAD patients. There are no advantages in adding strength training to conventional aerobic training. This study does not support the conclusion that combined training is a good strategy for these patients when compared with classic training.

Abstract
Background: This study aimed to investigate whether home exercise programs informed by wearable activity monitors improved walking ability of patients with peripheral artery disease (PAD). Methods: A systematic literature search was performed to identify randomised controlled trials (RCT) testing home exercise that were or were not informed by wearable activity monitors. The primary outcome was the change in walking distance measured by a six-minute walking test or treadmill test over the course of the trial. Network meta-analysis (NMA) was performed using the gemtc R statistical package. The risk of bias was assessed using Cochrane tool for assessing risk of bias in RCTs (RoB 2.0). Results: A total of 14 RCTs involving 1544 participants were included. Nine trials used wearable activity monitors to inform the home exercise program tested, while five trials did not use wearable activity monitors to inform the home exercise program tested. Overall quality assessment showed 12 trials to be at low risk of bias and two trials at high risk of bias. Home exercise programs informed by wearable activity monitors significantly improved walking distance compared to non-exercise controls (Mean difference, MD: 32.8 m [95% credible interval, CrI: 6.1, 71.0]) but not compared to home exercise programs not informed by wearable activity monitors (MD: 4.7 m [95% CrI: -38.5, 55.4]). Conclusions: Home exercise informed by wearable activity monitors improve walking ability of patients with PAD. It is, however, unclear if activity monitoring informed exercise programs are more effective than exercise programs not using activity monitors.

Abstract
This pilot randomised controlled trial aims to assess the feasibility and acceptability of a 12-week home-based telehealth exercise and behavioural intervention delivered in socioeconomically deprived patients with peripheral artery disease (PAD). The study will also determine the preliminary effectiveness of the intervention for improving clinical and health outcomes. Sixty patients with PAD who meet the inclusion criteria will be recruited from outpatient clinic at the Freeman Hospital, United Kingdom. The intervention group will undergo telehealth behaviour intervention performed 3 times per week over 3 months. This program will comprise a home-based exercise (twice a week) and an individual lifestyle program (once per week). The control group will receive general health recommendations and advice to perform unsupervised walking training. The primary outcome will be feasibility and acceptability outcomes. The secondary outcomes will be objective and subjective function capacity, quality of life, dietary quality, physical activity levels, sleep pattern, alcohol and tobacco use, mental wellbeing, and patients’ activation. This pilot study will provide preliminary evidence of the feasibility, acceptability and effectiveness of home-based telehealth exercise and behavioural intervention delivered in socioeconomically deprived patients with PAD. In addition, the variance of the key health outcomes of this pilot study will be used to inform the sample size calculation for a future fully powered, multicentre randomized clinical trial.

Abstract
Peripheral artery disease (PAD) is an atherosclerotic vascular disease resulting in widespread morbidity and mortality, particularly among older adults. One first-line therapy to improve symptoms, function, and clinical outcomes in PAD is supervised exercise therapy (SET), which is based primarily on a structured, start-and-stop walking protocol and is implemented in cardiac rehabilitation programs. SET is supported by a Class IA guideline for patients with symptomatic PAD; however, despite the effectiveness of SET and the 2017 CMS decision to cover SET for PAD, challenges of awareness, access, and implementation of SET persist. Recent efforts to address these challenges include digital health and hybrid approaches to SET that may minimize barriers to care by delivering SET in more innovative, flexible formats. Further study is needed to understand barriers, improve awareness, and implement SET in more equitable and accessible ways.

Abstract
In the management of symptomatic peripheral artery disease, aerobic exercise therapy and lower extremity revascularization are the mainstays of therapy. In this structured review, the most effective therapies, with 6 to 18 months of follow-up, indicated that exercise therapy and lower extremity revascularization each independently improve peak walking performance. The combination of therapies was superior to either therapy alone and may decrease the need for subsequent revascularization. Further research is needed to evaluate the long-term durability of these interventions, their impacts on subsequent invasive procedures, and predictors of response.
Exercise therapy and lower extremity revascularization both improve walking performance in symptomatic patients with peripheral artery disease. The combination of therapies provides greater benefit than either alone and may reduce the need for subsequent revascularization procedures, but further trials with longer follow-up are needed for the outcome of subsequent revascularization.

Abstract
BACKGROUND Peripheral artery disease (PAD) is the most underdiagnosed, underestimated and undertreated of the atherosclerotic vascular diseases despite its poor prognosis. There may be racial or contextual differences in the Asia-Pacific region as to epidemiology, availability of diagnostic and therapeutic modalities, and even patient treatment response. The Asian Pacific Society of Atherosclerosis and Vascular Diseases (APSAVD) thus coordinated the development of an Asia-Pacific Consensus Statement (APCS) on the Management of PAD. OBJECTIVES The APSAVD aimed to accomplish the following: 1) determine the applicability of the 2016 AHA/ACC guidelines on the Management of Patients with Lower Extremity Peripheral Artery Disease to the Asia-Pacific region; 2) review Asia-Pacific literature; and 3) increase the awareness of PAD. METHODOLOGY A Steering Committee was organized to oversee development of the APCS, appoint a Technical Working Group (TWG) and Consensus Panel (CP). The TWG appraised the relevance of the 2016 AHA/ACC PAD Guideline and proposed recommendations which were reviewed by the CP using a modified Delphi technique. RESULTS A total of 91 recommendations were generated covering history and physical examination, diagnosis, and treatment of PAD-3 new recommendations, 31 adaptations and 57 adopted statements. This Asia-Pacific Consensus Statement on the Management of PAD constitutes the first for the Asia-Pacific Region. It is intended for use by health practitioners involved in preventing, diagnosing and treating patients with PAD and ultimately the patients and their families themselves.

Abstract
Objective: To determine the effect of primary conservative treatment without revascularization in patients with proven aortoiliac occlusive disease (AIOD) presenting with intermittent claudication (IC).Background: The initial treatment of IC should focus on supervised exercise therapy (SET) and pharmacotherapy. Nowadays, primary endovascular revascularization (EVR) has become increasingly popular in patients with all types of AIOD. But in daily practice, EVR is often performed without initially extensive exercise.Method: This is a single centre retrospective study from December 2012 to September 2017. Primary outcomes were maximum walking distance (MWD) and patient satisfaction. Secondary outcomes were revascularization rate and mortality.Results: Twenty-four patients were included. Mean age was 64 years (SD: 9). Mean follow-up was 28 months (SD: 17). Nineteen patients (80%) had SET. In 18 (75%) patients, the MWD was improved compared to the initial situation. In five (21%) patients, the MWD stayed the same. The MWD of one (4%) patient decreased. Overall satisfaction rate was 87%. Three patients (13%) were not satisfied with the conservative treatment and eventually got an EVR. There was no disease related death.Conclusions: Conservative treatment, especially with SET, has acceptable subjective symptom outcomes in selected patients with AIOD. It could be a good alternative treatment for certain patients with AIOD and IC.

Abstract
Lower extremity peripheral artery disease (PAD) induces an ischemic pain in the lower limbs and leads to walking impairment. Electrical stimulation has been used in patients with PAD, but no systematic review has been proposed to address the efficacy of the technique as a treatment for walking impairment in PAD. A systematic search was performed to identify trials focused on electrical stimulation for the treatment of walking impairment in patients with PAD in the Cochrane Central Register, PubMed, Embase, and the Web of Science. Studies were included where the primary outcomes were pain-free walking distance and/or maximal walking distance. When appropriate, eligible studies were independently assessed for quality using the Cochrane Collaboration's tool for assessing risk of bias. Five studies eligible for inclusion were identified, of which only two were randomized controlled studies. Trial heterogeneity prevented the use of the GRADE system and the implementation of a meta-analysis. Three types of electrical stimulation have been used: neuromuscular electrical stimulation (NMES, n = 3), transcutaneous electrical stimulation (n = 1), and functional electrical stimulation (n = 1). The two available randomized controlled studies reported a significant improvement in maximal walking distance (+40 m/+34% and +39 m/+35%, respectively) following a program of NMES. Owing to the low number of eligible studies, small sample size, and the risk of bias, no clear clinical indication can be drawn regarding the efficacy of electrical stimulation for the management of impaired walking function in patients with PAD. Future high-quality studies are required to define objectively the effect of electrical stimulation on walking capacity.

Abstract
Background Underuse of guideline‐recommended therapy in peripheral artery disease (PAD) in administrative and procedural databases has been described, but reports on medically managed patients and referral to supervised exercise therapy (SET) in PAD are lacking. We aimed to document the use of PAD guideline‐recommended therapy, including SET in patients with PAD symptoms consulting a specialty clinic across 3 countries. Methods and Results The 16‐center PORTRAIT (Patient‐Centered Outcomes Related to Treatment Practices in Peripheral Arterial Disease: Investigating Trajectories) registry enrolled 1275 patients with new or an exacerbation of PAD symptoms (2011–2015). We prospectively documented antiplatelet medications, statins, smoking cessation counseling and/or therapy, and referral to SET: “2 quality measures” referred to the use of both statin and antiplatelet medications; “4 quality measures” to receiving all 4 measures. Median odds ratios were calculated to quantify treatment variation across sites. A total of 89% patients were on antiplatelets, 83% on statins, and 23% had been referred to SET. Of 455 current smokers, 342 (72%) patients received smoking cessation therapy/counseling. Overall, 77.2% of patients received “2 quality measures” and 19.7% “4 quality measures.” The median odds ratio for 2 quality measures was 2.13 (95% CI, 1.61–3.56; P<0.001) and for 4 quality measures was 5.43 (95% CI, 2.84–17.91; P<0.001). Variability in adherence was not explained by country, except for referral to SET. The odds for SET referral in The Netherlands (70% referral rate) was nearly 100 times greater than in US sites (2% referral rate). Conclusions Not all patients who have undergone a PAD workup at a specialty care facility are treated with evidence‐based care, especially so for SET.

Abstract
BACKGROUND The aim of this study was to investigate the costs and the health outcomes of primary care treatments for chronic diseases and to analyze the association between domains of quality of life (QoL), physical activity and healthcare costs. METHODS The sample encompassed 292 patients aged 50 years or more in Brazilian primary care facilities, categorized in three groups: no drug treatment or only regular physical activity, only drug treatment, and drug treatment with regular physical activity. Patients were assessed in relation to quality of life, healthcare costs, regular physical activity, and use of medications. RESULTS Results indicate higher cost-utility ratio among primary care patients adopting only drug treatment (3.92), followed by drug treatment with regular physical activity (3.21), and no drug treatment or only regular physical activity (0.12). CONCLUSIONS QoL was significantly associated with risk factors for chronic diseases, especially obesity, and limitations in mobility showed important increases in healthcare costs. The dominant strategy in terms of cost-utility ratio was identified among primary care patients without drug treatment or physically active, followed by patients in drug treatment combined with regular physical activity. Drug treatment without regular physical activity showed worst results in relation to other primary care strategies.

Abstract
Aims Prescribed exercise is effective in adults with coronary heart disease (CHD), chronic heart failure (CHF), intermittent claudication, body mass index (BMI) ≥25 kg/m2, hypertension or type 2 diabetes mellitus (T2DM), but the evidence for its cost-effectiveness is limited, shows large variations and is partly contradictory. Using World Health Organization and American Heart Association/American College of Cardiology value for money thresholds, we report the cost-effectiveness of exercise therapy, exercise training and exercise-based cardiac rehabilitation. Methods Electronic databases were searched for incremental cost-effectiveness and incremental cost–utility ratios and/or the probability of cost-effectiveness of exercise prescribed as therapy in economic evaluations conducted alongside randomized controlled trials (RCTs) published between 1 July 2008 and 28 October 2018. Results Of 19 incremental cost–utility ratios reported in 15 RCTs in patients with CHD, CHF, intermittent claudication or BMI ≥25 kg/m2, 63% met both value for money thresholds as ‘highly cost-effective’ or ‘high value’, with 26% ‘not cost-effective’ or of ‘low value’. The probability of intervention cost-effectiveness ranged from 23 to 100%, probably due to the different populations, interventions and comparators reported in the individual RCTs. Confirmation with the Consolidated Health Economic Evaluation Reporting checklist varied widely across the included studies. Conclusions The findings of this review support the cost-effectiveness of exercise therapy in patients with CHD, CHF, BMI ≥25 kg/m2 or intermittent claudication, but, with concerns about reporting standards, need further confirmation. No eligible economic evaluation based on RCTs was identified in patients with hypertension or T2DM.

Abstract
PURPOSE To determine the effect of revascularisation for peripheral arterial disease (PAD) on QoL in the first and second year following diagnosis, to compare the effect depicted by Short Form Six Dimensions (SF-6D) and EuroQoL five Dimensions (EQ-5D) utilities, and Visual Analogue Scale (VAS) scores and to analyse heterogeneity in treatment response. METHODS Longitudinal data from 229 PAD patients were obtained in an observational study in southern Netherlands. Utility scores were calculated with the international (SF-6D) and Dutch (EQ-5D) tariffs. We analysed treatment effect at years 1 and 2 through propensity score-matched ANCOVAs. Thereby, we estimated the marginal means (EMMs) of revascularisation and conservative treatment, and identified covariates of revascularisation effect. RESULTS A year after diagnosis, 70 patients had been revascularised; the EMMs of revascularisation were 0.038, 0.077 and 0.019 for SF-6D, EQ-5D and VAS, respectively (always in this order). For conservative treatment these were - 0.017, 0.038 and 0.021. At 2-year follow-up, the EMMs of revascularisation were 0.015, 0.077 and 0.027, for conservative treatment these were - 0.020, 0.013 and - 0.004. Baseline QoL (and rest pain in year 2) were covariates of treatment effect. CONCLUSIONS We measured positive effects of revascularisation and conservative treatment on QoL a year after diagnosis, the effect of revascularisation was sustained over 2 years. The magnitude of effect varied between the metrics and was largest for the EQ-5D, which may be most suitable for QoL measurement in PAD patients. Baseline QoL influenced revascularisation effect, in clinical practice this may inform expected QoL gain in individual patients.

Abstract
Objectives:The aim of this study is to review evidence on the cost-effectiveness of exercise-based interventions in the treatment of chronic conditions a decade after the publication of Roine et al. in 2009 (Roine E, Roine RP, Räsänen P, et al. Int J Technol Assess Health Care. 2009;25:427–454).Methods:We carried out a review of published articles in PUBMED and JSTOR between January 1, 2008, and December 31, 2016. Full economic evaluations of exercise programs targeting patients with a chronic condition were eligible for inclusion. Data on program, design, and economic characteristics were extracted using a predefined extraction form. The quality of the economic evaluations was appraised using the adjusted Consensus Health Economic Criteria List.Results:A total of 426 articles were identified and thirty-seven studies were selected. Eleven studies dealt with musculoskeletal and rheumatologic disorders, ten with cardiovascular diseases, six with neurological disorders, three with mental illnesses, three with cancers, and four with diabetes, respiratory diseases, or pelvic organ prolapse. In total, 60 percent of exercise programs were dominant or cost-effective. For musculoskeletal and rheumatologic disorders, 72 percent of programs were dominant or cost-effective while this was the case for 57 percent of programs for cardiovascular diseases using a nonsurgical comparator.Conclusions:There is clear evidence in favor of exercise-based programs for the treatment of musculoskeletal and rheumatologic disorders and, to a lesser extent, for the treatment of cardiovascular diseases. More research is needed to evaluate the cost-effectiveness of physical activity in the treatment of neurological disorders, mental illnesses, cancers, respiratory diseases, and diabetes/obesity.

Abstract
BACKGROUND Intermittent claudication (IC) is the classic symptomatic form of peripheral arterial disease affecting an estimated 4.5% of the general population aged 40 years and older. Patients with IC experience limitations in their ambulatory function resulting in functional disability and impaired quality of life (QoL). Endovascular revascularisation has been proposed as an effective treatment for patients with IC and is increasingly performed. OBJECTIVES The main objective of this systematic review is to summarise the (added) effects of endovascular revascularisation on functional performance and QoL in the management of IC. SEARCH METHODS For this review the Cochrane Vascular Information Specialist (CIS) searched the Specialised Register (February 2017) and the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 1). The CIS also searched trials registries for details of ongoing and unpublished studies. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing endovascular revascularisation (± conservative therapy consisting of supervised exercise or pharmacotherapy) versus no therapy (except advice to exercise) or versus conservative therapy (i.e. supervised exercise or pharmacotherapy) for IC. DATA COLLECTION AND ANALYSIS Two review authors independently selected studies, extracted data, and assessed the methodological quality of studies. Given large variation in the intensity of treadmill protocols to assess walking distances and use of different instruments to assess QoL, we used standardised mean difference (SMD) as treatment effect for continuous outcome measures to allow standardisation of results and calculated the pooled SMD as treatment effect size in meta-analyses. We interpreted pooled SMDs using rules of thumb (< 0.40 = small, 0.40 to 0.70 = moderate, > 0.70 = large effect) according to the Cochrane Handbook for Systematic Reviews of Interventions. We calculated the pooled treatment effect size for dichotomous outcome measures as odds ratio (OR). MAIN RESULTS We identified ten RCTs (1087 participants) assessing the value of endovascular revascularisation in the management of IC. These RCTs compared endovascular revascularisation versus no specific treatment for IC or conservative therapy or a combination therapy of endovascular revascularisation plus conservative therapy versus conservative therapy alone. In the included studies, conservative treatment consisted of supervised exercise or pharmacotherapy with cilostazol 100 mg twice daily. The quality of the evidence ranged from low to high and was downgraded mainly owing to substantial heterogeneity and small sample size.Comparing endovascular revascularisation versus no specific treatment for IC (except advice to exercise) showed a moderate effect on maximum walking distance (MWD) (SMD 0.70, 95% confidence interval (CI) 0.31 to 1.08; 3 studies; 125 participants; moderate-quality evidence) and a large effect on pain-free walking distance (PFWD) (SMD 1.29, 95% CI 0.90 to 1.68; 3 studies; 125 participants; moderate-quality evidence) in favour of endovascular revascularisation. Long-term follow-up in two studies (103 participants) showed no clear differences between groups for MWD (SMD 0.67, 95% CI -0.30 to 1.63; low-quality evidence) and PFWD (SMD 0.69, 95% CI -0.45 to 1.82; low-quality evidence). The number of secondary invasive interventions (OR 0.81, 95% CI 0.12 to 5.28; 2 studies; 118 participants; moderate-quality evidence) was also not different between groups. One study reported no differences in disease-specific QoL after two years.Data from five studies (n = 345) comparing endovascular revascularisation versus supervised exercise showed no clear differences between groups for MWD (SMD -0.42, 95% CI -0.87 to 0.04; moderate-quality evidence) and PFWD (SMD -0.05, 95% CI -0.38 to 0.29; moderate-quality evidence). Similarliy, long-term follow-up in three studies (184 participants) revealed no differences between groups for MWD (SMD -0.02, 95% CI -0.36 to 0.32; moderate-quality evidence) and PFWD (SMD 0.11, 95% CI -0.26 to 0.48; moderate-quality evidence). In addition, high-quality evidence showed no difference between groups in the number of secondary invasive interventions (OR 1.40, 95% CI 0.70 to 2.80; 4 studies; 395 participants) and in disease-specific QoL (SMD 0.18, 95% CI -0.04 to 0.41; 3 studies; 301 participants).Comparing endovascular revascularisation plus supervised exercise versus supervised exercise alone showed no clear differences between groups for MWD (SMD 0.26, 95% CI -0.13 to 0.64; 3 studies; 432 participants; moderate-quality evidence) and PFWD (SMD 0.33, 95% CI -0.26 to 0.93; 2 studies; 305 participants; moderate-quality evidence). Long-term follow-up in one study (106 participants) revealed a large effect on MWD (SMD 1.18, 95% CI 0.65 to 1.70; low-quality evidence) in favour of the combination therapy. Reports indicate that disease-specific QoL was comparable between groups (SMD 0.25, 95% CI -0.05 to 0.56; 2 studies; 330 participants; moderate-quality evidence) and that the number of secondary invasive interventions (OR 0.27, 95% CI 0.13 to 0.55; 3 studies; 457 participants; high-quality evidence) was lower following combination therapy.Two studies comparing endovascular revascularisation plus pharmacotherapy (cilostazol) versus pharmacotherapy alone provided data showing a small effect on MWD (SMD 0.38, 95% CI 0.08 to 0.68; 186 participants; high-quality evidence), a moderate effect on PFWD (SMD 0.63, 95% CI 0.33 to 0.94; 186 participants; high-quality evidence), and a moderate effect on disease-specific QoL (SMD 0.59, 95% CI 0.27 to 0.91; 170 participants; high-quality evidence) in favour of combination therapy. Long-term follow-up in one study (47 participants) revealed a moderate effect on MWD (SMD 0.72, 95% CI 0.09 to 1.36; P = 0.02) in favour of combination therapy and no clear differences in PFWD between groups (SMD 0.54, 95% CI -0.08 to 1.17; P = 0.09). The number of secondary invasive interventions was comparable between groups (OR 1.83, 95% CI 0.49 to 6.83; 199 participants; high-quality evidence). AUTHORS' CONCLUSIONS In the management of patients with IC, endovascular revascularisation does not provide significant benefits compared with supervised exercise alone in terms of improvement in functional performance or QoL. Although the number of studies is small and clinical heterogeneity underlines the need for more homogenous and larger studies, evidence suggests that a synergetic effect may occur when endovascular revascularisation is combined with a conservative therapy of supervised exercise or pharmacotherapy with cilostazol: the combination therapy seems to result in greater improvements in functional performance and in QoL scores than are seen with conservative therapy alone.

Abstract
The purpose of this study was to implement and evaluate quality outcomes including referral, enrollment, and completion rates of a new peripheral artery disease (PAD)-specific supervised exercise therapy (SET) program within a preexisting clinical exercise wellness program and to evaluate the clinical effectiveness and patient-centered outcomes derived from 12 weeks of PAD-specific SET. Recruited participants completed an individualized, minimally supervised, PAD-specific SET program based on the AHA-ACC guidelines. Exercise workloads (metabolic equivalents of task [METs]) were tracked and evaluated throughout the program. Short Physical Performance Battery, 6-minute walk test (6MWT) Walking Impairment Questionnaire, Short-Form 36 (SF-36), and Peripheral Artery Disease Quality of Life Questionnaire (PADQOL) were assessed before and after the program. Paired t-tests were used to examine differences between baseline and follow-up outcome variables. On average, participants (n = 46) attended 23 (standard deviation [SD] 12.9) out of the possible 36 training sessions, for a 64% attendance rate. Among participants who used treadmill walking as the primary mode of exercise (n = 40), the overall mean MET level just prior to program completion was 3.79 (SD 1.49), which represented an increase of 0.92 (34%) METs compared to baseline (P < .001). Total distance on the 6MWT increased 115 (11%) feet (P = .011), which is considered a clinically meaningful improvement. Significant improvements were noted in the PADQOL: symptoms and limitations in physical functioning (P = .007). This study demonstrates that a minimally staffed PAD-specific SET program can improve functional performance in patients with claudication due to PAD and serves as a foundation to help build a clinically effective, Centers for Medicare and Medicaid reimbursed PAD-specific rehabilitation program.

Cost analysis of iliac stenting performed in the operating room and the catheterization lab: A case-control study. Int J Surg 2016; 36:1-7. [PMID: 27746156 DOI: 10.1016/j.ijsu.2016.09.086] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2016] [Revised: 08/27/2016] [Accepted: 09/25/2016] [Indexed: 11/16/2022]
Abstract
BACKGROUND Iliac arterial stenting is performed both in the operating room (OR) and the catheterization lab (CL). To date, no analysis has compared resource utilization between these locations. METHODS Consecutive patients (n = 105) treated at a single center were retrospectively analyzed. Patients included adults with chronic, symptomatic iliac artery stenosis with a minimum Rutherford classification (RC) of 3, treated with stents. Exclusion criteria were prior stenting, acute ischemia, or major concomitant procedures. Immediate and two-year outcomes were observed. Patient demographics, perioperative details, physician billings, and hospital costs were recorded. Multivariable regression was used to adjust costs by patient and perioperative cost drivers. RESULTS Fifty-one procedures (49%) were performed in the OR and 54 (51%) in the CL. Mean age was 57, and 44% were female. Severe cases were more often performed in the OR (RC ≥ 4; 42% vs. 11%, P < 0.001) and were associated with increased total costs (P < 0.01). OR procedures more often utilized additional stents (stents ≥ 2; 61% vs. 46%, P = 0.214), thrombolysis (12% vs. 0%, P = 0.011), cut-down approach (8% vs. 0%, P = 0.052), and general anesthesia (80% vs. 0%, P < 0.001): these were all associated with increased costs (P < 0.05). After multivariable regression, location was not a predictor of procedure room or total costs but was associated with increased professional fees. Same-stay (5%) and post-discharge reintervention (33%) did not vary by location. CONCLUSIONS The OR was associated with increased length of stay, more ICU admissions, and increased total costs. However, OR patients had more severe disease and therefore often required more aggressive intervention. After controlling for these differences, procedure venue per se was not associated with increased costs, but OR cases incurred increased professional fees due to dual-provider charges. Given the similar clinical results between venues, it seems reasonable to perform most stenting in the CL or utilize conscious sedation in the OR.

Cost-effectiveness of supervised exercise therapy compared with endovascular revascularization for intermittent claudication. Br J Surg 2016; 103:1616-1625. [DOI: 10.1002/bjs.10247] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2016] [Revised: 04/07/2016] [Accepted: 05/04/2016] [Indexed: 11/09/2022]
Abstract
Abstract
Background
Current guidelines recommend supervised exercise therapy (SET) as the preferred initial treatment for patients with intermittent claudication. The availability of SET programmes is, however, limited and such programmes are often not reimbursed. Evidence for the long-term cost-effectiveness of SET compared with endovascular revascularization (ER) as primary treatment for intermittent claudication might aid widespread adoption in clinical practice.
Methods
A Markov model was constructed to determine the incremental costs, incremental quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratio of SETversus ER for a hypothetical cohort of patients with newly diagnosed intermittent claudication, from the Dutch healthcare payer's perspective. In the event of primary treatment failure, possible secondary interventions were repeat ER, open revascularization or major amputation. Data sources for model parameters included original data from two RCTs, as well as evidence from the medical literature. The robustness of the results was tested with probabilistic and one-way sensitivity analysis.
Results
Considering a 5-year time horizon, probabilistic sensitivity analysis revealed that SET was associated with cost savings compared with ER (−€6412, 95 per cent credibility interval (CrI) –€11 874 to –€1939). The mean difference in effectiveness was −0·07 (95 per cent CrI −0·27 to 0·16) QALYs. ER was associated with an additional €91 600 per QALY gained compared with SET. One-way sensitivity analysis indicated more favourable cost-effectiveness for ER in subsets of patients with low quality-of-life scores at baseline.
Conclusion
SET is a more cost-effective primary treatment for intermittent claudication than ER. These results support implementation of supervised exercise programmes in clinical practice.
