Intravascular Ultrasound Guidance During Peripheral Vascular Interventions: Long-term Clinical Outcomes and Costs From the Japanese Perspective.

Purpose: The value of intravascular ultrasound (IVUS) guidance during peripheral vascular revascularization procedures is incompletely understood. Moreover, data on long-term clinical outcomes and costs are limited. The objective of this study was to compare outcomes and costs between IVUS and contrast angiography alone in patients undergoing peripheral revascularization procedures in Japan.

A Budget Impact Model for the use of Drug-Eluting Stents in Patients with Symptomatic Lower-Limb Peripheral Arterial Disease: An Australian Perspective.

Purpose: Improvement in long-term outcomes through innovative, cost-effective medical technologies is a focus for endovascular procedures aimed at treating symptomatic lower-limb peripheral arterial disease (PAD). The advent of drug-eluting stents (DES) has improved symptomatic PAD treatment via a reduction in high rates of target lesion revascularisation (TLR). The present study aimed to compare the 5-year financial impact of treatment with Eluvia, a new paclitaxel-eluting stent, versus treatment with Zilver PTX, a drug-coated stent, among patients in Australia by developing a budget impact model (BIM).

The cost-effectiveness of guideline-driven use of drug-eluting stents: propensity-score matched analysis of a seven-year multicentre experience.

In routine clinical practice, the implantation of a drug-eluting stent (DES) versus a bare metal stent (BMS) for percutaneous coronary intervention (PCI) has been guided by criteria for appropriate use. The cost-effectiveness (CE) of adopting these guidelines, however, is not clear, and was investigated from the perspective of the Australian healthcare payer. Baseline and 12-month follow-up data of 12,710 PCI patients enrolled in the Melbourne Interventional Group (MIG) registry between 2004 and 2011 were analysed.

The Real-World Cost-Effectiveness of Coronary Artery Bypass Surgery Versus Stenting in High-Risk Patients: Propensity Score-Matched Analysis of a Single-Centre Experience.

Background: There are limited economic evaluations comparing coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) for multi-vessel coronary artery disease (MVCAD) in contemporary, routine clinical practice.

Objective: The aim was to perform a cost-effectiveness analysis comparing CABG and PCI in patients with MVCAD, from the perspective of the Australian public hospital payer, using observational data sources.

Methods: Clinical data from the Melbourne Interventional Group (MIG) and the Australian and New Zealand Society of Cardiac and Thoracic Surgeons (ANZSCTS) registries were analysed for 1022 CABG (treatment) and 978 PCI (comparator) procedures performed between June 2009 and December 2013.

Cost-Effectiveness of Pediatric Cochlear Implantation in Rural China.

Objectives: To evaluate the cost utility of cochlear implantation (CI) for severe to profound sensorineural hearing loss (SNHL) among children from rural settings in P.R. China (China).

A systematic review of cost-effectiveness of percutaneous coronary intervention vs. surgery for the treatment of multivessel coronary artery disease in the drug-eluting stent era.

Aims: The suitability of percutaneous coronary intervention (PCI), compared with coronary artery bypass grafting (CABG), for patients with complex multivessel coronary artery disease (MVCAD) remains a contentious topic. While the body of evidence regarding the clinical effectiveness of these revascularization strategies is growing, there is limited evidence concerning their long-term cost-effectiveness. We aim to critically appraise the body of literature investigating the cost-effectiveness of CABG compared with PCI using stents, and to assess the quality of the economic evidence available.

One-year experience with the Cochlear™ Paediatric Implanted Recipient Observational Study (Cochlear P-IROS) in New Delhi, India.

Background: Currently, there is a significant lack of data concerning long-term outcomes following paediatric cochlear implantation in terms of quality of life. There is a need for a long-term, prospective study in this regard. This study aims at highlighting the preliminary results, one year post surgery of a five year prospective study.

A global patient outcomes registry: Cochlear paediatric implanted recipient observational study (Cochlear(™) P-IROS).

Background: Currently, there is a paucity of data concerning the long-term outcomes, educational placement and quality of life of children implanted with hearing devices from large and representative samples of the population. To address this concern, a large, prospective, multicentre, multinational patient-outcomes registry for paediatric recipients of implantable hearing devices was developed. The benefits of this registry, its approach and methodology are described.

Prolonged effectiveness of coronary artery bypass surgery versus drug-eluting stents in diabetics with multi-vessel disease: an updated systematic review and meta-analysis.

Background: Currently, the appropriateness of percutaneous coronary intervention (PCI) using drug-eluting stents (DES) versus coronary artery bypass grafting (CABG) for patients with diabetes (DM) and multi-vessel disease (MVD) is uncertain due to limited evidence from few randomised controlled trials (RCTs). We aimed to compare the clinical effectiveness of CABG versus PCI-DES in DM-MVD patients using an evidence-based approach.

Methods: A systematic review and meta-analyses were conducted to compare the risk of all-cause mortality, myocardial infarction (MI), repeat revascularisation, cerebrovascular events (CVE), and major adverse cardiac or cerebrovascular events (MACCE).

Cardiovascular readmissions and excess costs following percutaneous coronary intervention in patients with chronic kidney disease: data from a large multi-centre Australian registry.

Background: Chronic kidney disease (CKD) is a well-established risk factor for adverse events in patients undergoing percutaneous coronary intervention (PCI). However, few data exists on the subsequent healthcare resource use and related incremental costs in this patient subgroup. The present study compares the rates of cardiac-related hospitalisations and the associated direct costs, post-PCI in patients with and without CKD.

An Australian risk prediction model for determining early mortality following aortic valve replacement.

Objective: To develop a multivariable logistic risk model for predicting early mortality following aortic valve replacement (AVR) in adults, and to compare its performance against existing AVR-dedicated models.

Methods: Prospectively collected data from the Australasian Society of Cardiac and Thoracic Surgeons (ASCTS) database project were used. Thirty-five preoperative variables from AVR literature were considered for analysis by chi-square method and multiple logistic regression.
