Health Literacy in the Context of Implant Care-Perspectives of (Prospective) Implant Wearers on Individual and Organisational Factors. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:6975. [PMID: 35742224 PMCID: PMC9222238 DOI: 10.3390/ijerph19126975] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 05/03/2022] [Revised: 06/03/2022] [Accepted: 06/05/2022] [Indexed: 02/01/2023]
Abstract
The continuous development of medical implants offers various benefits for persons with chronic conditions but also challenges an individual's, and the healthcare system's, ability to deal with technical innovation. Accessing and understanding new information, navigating healthcare, and appraising the role of the implant in body perceptions and everyday life requires health literacy (HL) of those affected as well as an HL-responsive healthcare system. The interconnectedness of these aspects to ethically relevant values such as health, dependence, responsibility and self-determination reinforces the need to address HL in implant care. Following a qualitative approach, we conducted group discussions and a diary study among wearers of a cochlear, glaucoma or cardiovascular implant (or their parents). Data were analysed using the documentary method and grounded theory. The data reveal the perceptions of implant wearers regarding the implant on (1) the ability to handle technical and ambiguous information; (2) dependence and responsibility within the healthcare system; and (3) the ethical aspects of HL. Knowing more about the experiences and values of implant wearers is highly beneficial to develop HL from an ethical perspective. Respective interventions need to initially address ethically relevant values in counselling processes and implant care.

Identifying New Factors Associated With Cognitive Decline and Delirium After Transcatheter Aortic Valve Implantation: A Study Protocol. Front Cardiovasc Med 2021; 8:657057. [PMID: 34458327 PMCID: PMC8385234 DOI: 10.3389/fcvm.2021.657057] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2021] [Accepted: 07/14/2021] [Indexed: 12/11/2022] Open
Abstract
Background: Transcatheter aortic valve implantation (TAVI) has become the standard-of-care for treatment of severe symptomatic aortic stenosis and is also being increasingly recommended for low-risk patients. While TAVI boasts positive post-procedural outcomes, it is also associated with cognitive complications, namely delirium and cognitive decline. There is a pressing need for accurate risk tools which can identify TAVI patients at risk of delirium and cognitive decline, as risk scores designed for general cardiovascular surgery fall short. The present effect-finding exploratory study will assess the utility of various measures in the context of aging and frailty in predicting who will and who will not develop delirium or cognitive impairment following TAVI. The measures we propose include gait, visual symptoms, voice, swallowing, mood and sleep. Methods: This is an observational prospective cohort study focused on identifying pre-procedural risk factors for the development of delirium and cognitive decline following TAVI. Potential risk factors will be measured prior to TAVI. Primary outcomes will be post-procedure cognitive decline and delirium. Secondary outcomes include activities of daily living, quality of life, and mortality. Delirium presence will be measured on each of the first 2 days following TAVI. All other outcomes will be assessed at 3-, 6-, and 12-months post-operatively. A series of logistic regressions will be run to investigate the relationship between potential predictors and outcomes (presence vs. absence of either delirium or cognitive decline). Discussion: This study will assess the strengths of associations between a range of measures drawn from frailty and aging literature in terms of association with cognitive decline and delirium following TAVI. Identified measures can be used in future development of TAVI risk prediction models, which are essential for the accurate identification of cognitive at-risk patients and successful application of pre-procedural interventions. Clinical Trial Registration: This trial is registered with the Australian New Zealand Clinical Trials Registry. [https://bit.ly/2PAotP5], [ACTRN12618001114235].

Cost analysis of transcatheter versus surgical aortic valve replacement in octogenarians: analysis from a single Japanese center. Heart Vessels 2021; 36:1558-1565. [PMID: 33710376 DOI: 10.1007/s00380-021-01826-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/15/2020] [Accepted: 03/05/2021] [Indexed: 11/27/2022]
Abstract
Transcatheter aortic valve replacement (TAVR) has revolutionized the prognosis of intermediate- or high-risk patients with severe aortic stenosis, particularly among older adults. However, in possible candidates for surgical aortic valve replacement (SAVR), the implantation of expensive prostheses may be questionable in an era when healthcare costs are becoming a major concern. In this retrospective analysis of a single Japanese center, we focused on patients aged over 80 years; the objectives of this study were: (1) to compare TAVR and SAVR in terms of total hospitalization costs and (2) to describe the itemized cost of TAVR and SAVR to identify patients aged over 80 years in whom TAVR or SAVR would be cost-effective. A total of 146 patients aged over 80 years who underwent TAVR or SAVR for severe aortic stenosis were included. These patients were divided into a high-risk group (Society of Thoracic Surgeons [STS] mortality score > 8%; 36: TAVR and 12: SAVR) with 48 patients and a non-high-risk group (STS mortality score < 8%; 45: TAVR and 53 SAVR) with 98 patients. No 30-day mortality was observed in either group. In both groups, postoperative intensive care unit stay and hospital stay were longer with SAVR than with TAVR. In the non-high-risk group, the total cost was comparable for TAVR and SAVR; however, in the high-risk group, the total cost was significantly higher with SAVR than that with TAVR. A breakdown analysis of the total cost in the high-risk group showed both pre- and postoperative costs to be significantly higher with SAVR than with TAVR; however, operative costs were higher with TAVR. Up to 3 years, the overall survival in both groups did not significantly differ between TAVR and SAVR. Our findings suggest that from the perspective of total medical costs, TAVR is more suitable than SAVR for high-risk older adults.

Abstract
Ungeachtet der sozialgesetzlichen Vorgaben existieren im deutschen Gesundheitssystem in der Patientenversorgung nebeneinander Unter‑, Fehl- und Überversorgung. Überversorgung bezeichnet diagnostische und therapeutische Maßnahmen, die nicht angemessen sind, da sie die Lebensdauer oder Lebensqualität der Patienten nicht verbessern, mehr Schaden als Nutzen verursachen und/oder von den Patienten nicht gewollt werden. Daraus können hohe Belastungen für die Patienten, deren Familien, die Behandlungsteams und die Gesellschaft resultieren. Dieses Positionspapier erläutert Ursachen von Überversorgung in der Intensivmedizin und gibt differenzierte Empfehlungen zu ihrer Erkennung und Vermeidung. Zur Erkennung und Vermeidung von Überversorgung in der Intensivmedizin erfordert es Maßnahmen auf der Mikro‑, Meso- und Makroebene, insbesondere die folgenden: 1) regelmäßige Evaluierung des Therapieziels im Behandlungsteam unter Berücksichtigung des Patientenwillens und unter Begleitung von Patienten und Angehörigen; 2) Förderung einer patientenzentrierten Unternehmenskultur im Krankenhaus mit Vorrang einer qualitativ hochwertigen Patientenversorgung; 3) Minimierung von Fehlanreizen im Krankenhausfinanzierungssystem gestützt auf die notwendige Reformierung des fallpauschalbasierten Vergütungssystems; 4) Stärkung der interdisziplinären/interprofessionellen Zusammenarbeit in Aus‑, Fort- und Weiterbildung; 5) Initiierung und Begleitung eines gesellschaftlichen Diskurses zur Überversorgung.

Cost and contribution margin of transcatheter versus surgical aortic valve replacement. J Thorac Cardiovasc Surg 2017; 154:1872-1880.e1.

Abstract
OBJECTIVE To compare the cost of and payments for transcatheter aortic valve replacement (TAVR), a novel and expensive technology, and surgical aortic valve replacement (SAVR). METHODS Medicare claims provided hospital charges, payments, and outcomes between January and December 2012. Hospital costs and charges were estimated using hospital-specific cost-to-charge ratios. Costs and payments were examined in propensity score- matched TAVR and SAVR patients. RESULTS Medicare spent $215,770,200 nationally on 4083 patients who underwent TAVR in 2012. Hospital costs were higher for TAVR patients (median, $50,200; interquartile range [IQR], $39,800-$64,300) than for propensity-matched SAVR patients ($45,500; IQR, $34,500-$63,300; P < .01), owing largely to higher estimated medical supply costs, including the implanted valve prosthesis. Postprocedure hospital length of stay (LOS) length was shorter for TAVR patients (median, 5 days [IQR, 4-8 days] vs 7 days [IQR, 5-9 days]; P < .01), as was total intensive care unit (ICU) LOS (median, 2 days [IQR, 0-5 days] vs 3 days [IQR, 1-6 days]; P < .01). Medicare payments were lower for TAVR hospitalizations (median, $49,500; IQR, $36,900-$64,600) than for SAVR (median, $50,400; IQR, $37,400-$65,800; P < .01). The median of the differences between payments and costs (contribution margin) was -$3380 for TAVR hospitalizations and $2390 for SAVR hospitalizations (P < .01). CONCLUSIONS TAVR accounted for $215 million in Medicare payments in its first year of clinical use. Among SAVR Medicare patients at a similar risk level, TAVR was associated with higher hospital costs despite shorter ICU LOS and hospital LOS. Overall and/or medical device cost reductions are needed for TAVR to have a net neutral financial impact on hospitals.

Abstract
Medical devices (MDs) have distinctive features, such as incremental innovation, dynamic pricing, the learning curve and organisational impact, that need to be considered when they are evaluated. This paper investigates how MDs have been assessed in practice, in order to identify methodological gaps that need to be addressed to improve the decision-making process for their adoption. We used the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist supplemented by some additional categories to assess the quality of reporting and consideration of the distinctive features of MDs. Two case studies were considered: transcatheter aortic valve implantation (TAVI) representing an emerging technology and implantable cardioverter defibrillators (ICDs) representing a mature technology. Economic evaluation studies published as journal articles or within Health Technology Assessment reports were identified through a systematic literature review. A total of 19 studies on TAVI and 41 studies on ICDs were analysed. Learning curve was considered in only 16% of studies on TAVI. Incremental innovation was more frequently mentioned in the studies of ICDs, but its impact was considered in only 34% of the cases. Dynamic pricing was the most recognised feature but was empirically tested in less than half of studies of TAVI and only 32% of studies on ICDs. Finally, organisational impact was considered in only one study of ICDs and in almost all studies on TAVI, but none of them estimated its impact. By their very nature, most of the distinctive features of MDs cannot be fully assessed at market entry. However, their potential impact could be modelled, based on the experience with previous MDs, in order to make a preliminary recommendation. Then, well-designed post-market studies could help in reducing uncertainties and make policymakers more confident to achieve conclusive recommendations. © 2017 The Authors.

Abstract
AIM We investigated the diffusion of transcatheter aortic valve implantation (TAVI) since its introduction into the Italian market aimed at identifying the potential drivers of uptake and diffusion at hospital and regional levels. MATERIALS & METHODS We estimated the determinants of TAVI diffusion in Italy from 2007 to 2015 with a regression analysis based on registry data. RESULTS Since 2007, TAVI has shown significant diffusion rates in Italy. The diffusion is positively correlated with implanting centers' experience and with the presence of key opinion leaders. Regional recommendations on the use of TAVI negatively influence the diffusion. Reimbursement policies do not exert a relevant impact. CONCLUSION Learning effect seems to be the major driver of TAVI diffusion in Italy.

Abstract
BACKGROUND In the symptomatic patient, severe aortic stenosis (AS) has an extremely adverse prognosis in the absence of valve replacement, inevitably leading to deterioration of heart function, heart failure, and death. However, many patients with severe AS, advanced age, and comorbid disease may die with AS rather than from AS. While the results of surgical aortic valve replacement (SAVR) are extremely favorable, this technique is not always possible because of either local- or patient-level contraindications. Over the last decade, transcatheter aortic valve replacement (TAVR) has emerged as a new treatment strategy for selected patients with AS. It has now become the standard of care for extremely high-risk (inoperable) patients with AS, and is an appropriate alternative to surgery in high-risk but operable patients. However, whether this intervention is a cost-effective use of resources is open to question AIM The aim of this review was to assess the results and quality of the economic evaluations in the current literature and to identify the drivers of cost effectiveness. METHODS We performed an electronic data search using four different electronic databases, selecting all studies that included cost-effectiveness data for TAVR compared with either medical management or surgery. Sixteen studies were evaluated for a qualitative and quantitative assessment. RESULTS The quality of the cost-effectiveness analyses (CEAs) were generally sufficient. In contrast, we found an extreme heterogeneity of input assumptions with consequent difficulties to generalize the conclusions. However, in the population of patients with severe symptomatic AS and a prohibitive surgical risk, TAVR generally represents a good choice, with incremental costs that are well balanced by the great benefit in terms of quality of life and survival. Nevertheless, the cost effectiveness of this procedure in the real world, particularly in patients with high healthcare costs from other comorbid conditions, may be less favorable. In AS patients with high (but not prohibitive) surgical risk, the choice between TAVR and SAVR is still debatable. Both procedures are comparable in terms of efficacy and safety but the evidence is inconclusive from an economic point of view. CONCLUSIONS On the basis of this review, it was ascertained that the details of risk evaluation and patient selection will be critical in understanding how improvements in survival can be used to target the use of TAVR to ensure the cost-effective and sustainable use of resources.

Abstract
BACKGROUND The functional and quality-of-life benefits of transcatheter aortic valve replacement (TAVR) have not been established. PURPOSE To evaluate the changes in functional status and quality of life after TAVR. DATA SOURCES MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials from 1 January 2002 to 30 September 2013. STUDY SELECTION Studies of TAVR that reported the New York Heart Association (NYHA) class, Short Form-12/36 Health Survey physical and mental component summary (points), or other measures of functional status. DATA EXTRACTION Two reviewers independently extracted the mean change (follow-up minus baseline) in primary outcomes. Because of substantial heterogeneity, data were not pooled; the range of mean change was summarized. DATA SYNTHESIS We identified 60 observational studies (56 pre–post comparison and 4 head-to-head comparative studies) and 2 randomized, controlled trials (11 205 patients). Most studies showed a clinically important decrease in NYHA class at 6 to 11 months (range, -0.8 to -2.1 classes) and 12 to 23 months (range, -0.8 to -2.1 classes). The improvement in the Short Form-12/36 Health Survey physical component score was clinically important over 12 months (range, 4.9 to 26.9 points), and the change in mental component score was smaller (range, 1.0 to 8.9 points).Clinically important improvements were seen in other disease-specific measures but were less consistently seen in general health measures. LIMITATIONS Comparative evidence is limited by few head-to-head studies. Survivor bias may have overestimated the benefits. CONCLUSION Transcatheter aortic valve replacement provides clinically important benefits in physical function and disease-specific measures of quality of life but modest benefits in psychological and general health measures. More comparative studies on functional status and quality of life are needed for informed treatment decision making.

Imaging for approach selection of TAVI: assessment of the aorto-iliac tract diameter by computed tomography-angiography versus projection angiography. Int J Cardiovasc Imaging 2013; 30:399-405.

Abstract
The choice of preferred access route for transcatheter aortic valve implantation (TAVI) is mainly guided by the minimal aorto-femoral tract diameter. Currently, projection angiography (XA) and CT-angiography (CTA) are used interchangeably to assess this diameter in the TAVI work-up. We aimed to assess the agreement of XA and CTA diameter measurements in TAVI candidates. Diameters of 700 aorta-iliac segments of 102 TAVI candidates were analyzed on both XA and CTA. The diameters on XA were measured manually, for the CTA-based analysis semi-automated segmentation software was used. Paired sample T test was used to evaluate differences in diameter measurements between the modalities. Disagreement on the suitability for a transfemoral (TF)-TAVI approach was identified. The interobserver agreement for both measurements was assessed by calculating the intraclass correlation coefficient (ICC). The average diameters were 10.1 ± 1.8 mm and 8.4 ± 1.7 for XA and CTA respectively. The mean paired difference was 1.73 mm (p < 0.001). For 18 patients (17.6 %) diameters measured on CTA images, were bilaterally less than 6 mm, whilst XA indicated a minimum diameter exceeding 6 mm. For both modalities, the interobserver agreement was excellent (ICC 0.95). Diameters measured semi-automatically on CTA were statistically significantly smaller compared to XA. This should be acknowledged in the work-up for selecting the most appropriate approach for TAVI. In our population 17.6 % of patients would have been denied a transfemoral TAVI based on CTA measurements, whilst XA suggested diameters sufficient for a TF approach.
