Management practices and the quality of care in cardiac units

Importance:- To improve the quality of health care, many researchers have suggested that health care institutions adopt management approaches that have been successful in the manufacturing and technology sectors. However, relatively little information exists about how these practices are disseminated in hospitals and whether they are associated with better performance. Objectives:- To describe the variation in management practices among a large sample of hospital cardiac care units; assess association of these practices with processes of care, readmissions, and mortality for patients with acute myocardial infarction (AMI); and suggest specific directions for the testing and dissemination of health care management approaches. Design:- We adapted an approach used to measure management and organizational practices in manufacturing to collect management data on cardiac units. We scored performance in 18 practices using the following 4 dimensions: standardizing care, tracking of key performance indicators, setting targets, and incentivizing employees. We used multivariate analyses to assess the relationship of management practices with process-of-care measures, 30-day risk-adjusted mortality, and 30-day readmissions for acute myocardial infarction (AMI). Setting:- Cardiac units in US hospitals. Participants_ Five hundred ninety-seven cardiac units, representing 51.5% of hospitals with interventional cardiac catheterization laboratories and at least 25 annual AMI discharges. Main Outcome Measures:- Process-of-care measures, 30-day risk-adjusted mortality, and 30-day readmissions for AMI. Results:- We found a wide distribution in management practices, with fewer than 20% of hospitals scoring a 4 or a 5 (best practice) on more than 9 measures. In multivariate analyses, management practices were significantly correlated with mortality (P = .01) and 6 of 6 process measures (P < .05). No statistically significant association was found between management and 30-day readmissions. Conclusions and Relevance:- The use of management practices adopted from manufacturing sectors is associated with higher process-of-care measures and lower 30-day AMI mortality. Given the wide differences in management practices across hospitals, dissemination of these practices may be beneficial in achieving high-quality outcomes. Interest in quality improvement in health care during the past 10 years has been associated with a handful of important successes.1- 3 However, improvements in the quality of care have been slower than many would have hoped for,4- 8 and quality is still highly variable across organizations.9 Although significant effort has been focused on the use of evidence-based medicine—clinical practices that lead to better care—an interest in organizational strategies and management practices that enable and incentivize high-quality health care is emerging.10- 15 One of the most active areas of interest is in the use of management practices with origins in manufacturing, including, for example, “Lean” methodologies developed at Toyota16 or the use of balanced scorecard approaches that originated in the technology sector.17 These management approaches can be characterized as a set of formalized tools, the use of which is intended to improve quality through multiple pathways, such as eliminating inefficient and variable practices; engaging providers in a collaborative, team-based approach; and structuring mechanisms for setting targets and tracking progress. However, the evidence on the potential effectiveness of these approaches in health care is relatively weak13,18 and consists primarily of single-site studies.19- 21 To address this gap in knowledge, we present a new framework and instrument for defining key management dimensions and for measuring them on a large scale in health care organizations. We describe the variation in management practices among a large sample of hospitals; assess its association with processes of care, readmissions, and mortality for patients with acute myocardial infarction (AMI); and suggest specific directions for the testing and dissemination of health care management approaches

Identification of complex health interventions suitable for evaluation: development and validation of the 8-step scoping framework

Background: There is extensive literature on the methodology of evaluation research and the development and evaluation of complex interventions but little guidance on the formative stages before evaluation and how to work with partner organizations that wish to have their provision evaluated. It is important to be able to identify suitable projects for evaluation from a range of provision and describe the steps required, often with academic institutions working in partnership with external organizations, in order to set up an evaluation. However, research evaluating programs or interventions rarely discusses these stages. Objective: This study aimed to extend work on evaluability assessment and pre-evaluation planning by proposing an 8-Step Scoping Framework to enable the appraisal of multiple programs in order to identify interventions suitable for evaluation. We aimed to add to the literature on evaluability assessment and more recent evaluation guidance by describing the processes involved in working with partner organizations. Methods: This paper documents the steps required to identify multiple complex interventions suitable for process and outcome evaluation. The steps were developed using an iterative approach by working alongside staff in a local government organization, to build an evidence base to demonstrate which interventions improve children’s outcomes. The process of identifying suitable programs for evaluation, thereby establishing the pre-evaluation steps, was tested using all Flying Start provision. Results: The 8-Step Scoping Framework was described using the example of the local government organization Flying Start to illustrate how each step contributes to finding projects suitable for process and outcome evaluation: (1) formulating overarching key questions that encompass all programs offered by an organization, (2) gaining an in-depth understanding of the work and provision of an organization and engaging staff, (3) completing a data template per project/program offered, (4) assessing the robustness/validity of data across all programs, (5) deciding on projects suitable for evaluation and those requiring additional data, (6) negotiating with chosen project leads, both within and outside the organization, (7) developing individual project evaluation protocols, and (8) applying for ethical approval from the university and partner organization. Conclusions: This paper describes the processes involved in identifying suitable projects for evaluation. It adds to the existing literature on the assessment of specific programs suitable for evaluation and guidance for conducting evaluations by establishing the formative steps required to identify suitable programs from a range of provision. This scoping framework particularly relates to academic partners and organizations tasked with delivering evidence-based services designed to meet local needs. The steps identified have been described in the context of early years provision but can be applied to a range of community-based evaluations, or more generally, to cases where an academic partner is working with external stakeholders to identify projects suitable for academic evaluation

Carotid Artery Stenting Using a Novel Self-Expanding Braided Nickel–Titanium Stent: Feasibility and Safety Porcine Trial

We studied the deliverability and safety of a braided, self-expanding, closed-cell nickel–titanium (NiTi) stent (E-volution, Jotec GmbH, Hechingen, Germany) especially designed for the endovascular treatment of carotid artery bifurcation stenosis with special regard to in-stent stenosis and thrombosis compared with a laser-cut reference nitinol stent in a porcine model of percutaneous vascular interventions. We aimed to assess histopathologic response in minipig carotid and subclavian arteries. Eight minipigs received a total of 42 stents: 14 reference stents and 28 E-volution stents. Eleven of the E-volution stents were additionally coated with heparin. Control angiography was obtained immediately before and after vascular intervention as well as 4 weeks after the procedure. Primary endpoints were 28 days of angiographic analyses as well as histomorphometric analysis, including injury score, inflammation score, luminal diameter, vessel diameter, maximal neointimal thickness, and area of in-stent stenosis. Secondary end points were procedural success, 28-day mortality, and stent thrombosis. All stents could be delivered successfully without procedural complications, morbidity, or mortality during our observation time. As confirmed by histology, no in-stent thrombosis was observed. Compared with common carotid arteries, subclavian arteries are significantly more vulnerable to developing in-stent stenosis caused by neointima proliferation (p < 0.05). Compared with the use of 1 single stent/artery, serial application of two stents leads to a more excessive but not significantly different neointimal proliferation (p > 0.05). The E-volution stent, especially when heparin coated, is in line with the comparison to the laser-cut reference stent displaying similar results of angiographic, histologic, and histomorphometric analyses (p > 0.05). Compared with the reference laser-cut stent, the self-expanding nitinol stent (E-volution) with its advanced braiding technology is feasible and safe. In our opinion, the high radial resistive force and the advanced braided design with tight stent-strut interstices may be beneficial in terms of plaque stabilization. Further studies are necessary and warranted

Successful interdisciplinary management of the misdeployment of two self-expanding stents into the internal carotid artery: a case report

<p>Abstract</p> <p>Introduction</p> <p>With the widespread use of carotid artery stenting, previously unknown technical mistakes of this treatment modality are now being encountered. There are multiple strategies for the treatment of in-stent restenosis. With regard to surgical management, endarterectomy and patch plasty are favored. To the best of our knowledge, this report is the first description of a complete stent removal by the eversion technique.</p> <p>Case presentation</p> <p>We report the case of a 63-year-old Caucasian man with misdeployment of two stents into his stenotic proximal internal carotid artery, resulting in a high-grade mechanical obstruction of the internal carotid artery lumen. With the contralateral internal carotid artery already occluded and associated stenoses of both proximal and distal vertebral arteries, an interdisciplinary therapeutic concept was applied. Bilateral balloon angioplasty and stenting of the proximal and distal stenotic vertebral arteries were carried out to provide sufficient posterior collateral blood flow, followed by successful surgical stentectomy and carotid endarterectomy using the eversion technique. Duplex scanning and neurological assessments were normal over a 12-month follow-up period.</p> <p>Conclusions</p> <p>Interdisciplinary treatment is a recommended option to protect patients from further impairment. Further evaluation in larger studies is highly recommended.</p

<p>Abstract</p> <p>Introduction</p> <p>Hemoptysis constitutes a common and urgent medical problem. Swift and effective management is of crucial importance, especially in severe, life-threatening cases. In cases of idiopathic hemoptysis, in which no underlying pulmonary pathology can be identified, treatment is challenging. We report our experience with bronchial artery embolization in the treatment of massive idiopathic hemoptysis.</p> <p>Cases presentation</p> <p>We report three consecutive cases of acute severe idiopathic hemoptysis. Our patients (two men aged 51 and 56 years and one woman aged 46 years), were of Caucasian ethnicity. We discuss the results and management of the patients, and review the literature. All three patients were treated safely and successfully with transcatheter embolization of the bronchial arteries using tris-acryl gelatin microspheres. Hemoptysis was controlled. All cases were followed up for 12 months, and there was no recurrence of bleeding.</p> <p>Conclusion</p> <p>Bronchial artery embolization is an effective tool for the evaluation and treatment of massive idiopathic hemoptysis.</p

From theory to practice: improving the impact of health services research

BACKGROUND: While significant strides have been made in health research, the incorporation of research evidence into healthcare decision-making has been marginal. The purpose of this paper is to provide an overview of how the utility of health services research can be improved through the use of theory. Integrating theory into health services research can improve research methodology and encourage stronger collaboration with decision-makers. DISCUSSION: Recognizing the importance of theory calls for new expectations in the practice of health services research. These include: the formation of interdisciplinary research teams; broadening the training for those who will practice health services research; and supportive organizational conditions that promote collaboration between researchers and decision makers. Further, funding bodies can provide a significant role in guiding and supporting the use of theory in the practice of health services research. SUMMARY: Institutions and researchers should incorporate the use of theory if health services research is to fulfill its potential for improving the delivery of health care

A systematic review of sport-based life skills programs for young people: The quality of design and evaluation methods

Over the past two decades, researchers have reported positive life skills outcomes for young people participating in sport-based lifeskills programs. However, to date, there has been a lack of consideration in the literature regarding the quality of the programs designed and the evaluation methods adopted. Therefore, we conducted a systematic review of the life skills literature to: (a) assess the quality of sport-based life skills program design and evaluation methods; and (b) identify characteristics relating to the quality of sport-based life skills programs where authors had evidenced life skills development and transfer. Using the PRISMA guidelines, we searched six databases for relevant research papers and applied inclusion and exclusion criteria to the papers returned, of which 15 papers met the criteria. We conducted two quality assessment exercises (design and evaluation methods) and found three moderate high quality life skills programs, 11 moderate quality programs, and one low quality program. We present the characteristics (regarding quality) of intervention designs and methods, conclude with recommendations for designing quality sport-based life skills programs, and provide guidelines for researchers to evaluate sport-based life skills programs. Lay summary: Through engaging in sport-based life skills programs, young people can develop transferable skills. However, the quality of these life skills programs is unclear. We assess the quality of the design and evaluation methods of sport-based life skills programs, present the characteristics of moderate-high and moderate quality programs, and offer recommendations for future research and practice

Integrating the data envelopment analysis and the balanced scorecard approaches for enhanced performance assessment

This article presents the development of a conceptual framework which aims to assess Decision Making Units (DMUs)from multiple perspectives. The proposed conceptual framework combines the Balanced Scorecard(BSC)method with the non-parametric technique known as Data Envelopment Analysis (DEA) by using various interconnected models which try to encapsulate four perspectives of performance (financial, customers, internal processes,learning and growth). The practical relevance of the conceptual model has been tested by using it to assess the performance of DMUs in a multinational company which operates in two business areas.Various models were developed with the collaboration of the directors of the company in order to conceive an appropriate and consensual framework, which may provide useful information for the company.The application of the conceptual framework provides structured information regarding the performance of each DMU(from multiple perspectives)and ways to improve it.By integrating the BSC and the DEA approaches this research helps to identify where there is room for improving organisational performance and points out opportunities for reciprocal learning between DMUs.In doing so,this article provides a set of recommendations relating to the successful application of DEA and its integration with the BSC,in order to promote a continuous learning process and to bring about improvements in performance

Canagliflozin attenuates the progression of atherosclerosis and inflammation process in APOE knockout mice

Background: Sodium glucose co-transporter2 inhibitors reduce the incidence of cardiovascular events in patients with type 2 diabetes mellitus based on the results of recent cardiovascular outcome studies. Herein, we investigated the efects of long-term treatment with canaglifozin on biochemical and immunohistochemical markers related to atherosclerosis and atherosclerosis development in the aorta of apolipoprotein E knockout (Apo-E(−/−) ) mice. Methods: At the age of 5 weeks, mice were switched from normal to a high-fat diet. After 5 weeks, Apo-E(−/−) mice were divided into control-group (6 mice) treated with 0.5% hydroxypropyl methylcellulose and Cana-group (7 mice) treated with canaglifozin (10 mg/kg per day) per os. After 5 weeks of intervention, animals were sacrifced, and heart and aorta were removed. Sections stained with hematoxylin–eosin (H&E) were used for histomorphometry whereas Masson’s stained tissues were used to quantify the collagen content. Immunohistochemistry to assess MCP-1, CD68, a-smooth muscle actin, MMP-2, MMP-9, TIMP-1 and TIMP-2 expression was carried out and q-PCR experiments were performed to quantify mRNA expression. Results: Canaglifozin-group mice had lower total-cholesterol, triglycerides and glucose levels (P<0.01), while heart rate was signifcantly lower (P<0.05). Histomorphometry revealed that one in seven Cana-group mice versus four in six control mice developed atheromatosis, while aortic root plaque was signifcantly less, and collagen was 1.6 times more intense in canaglifozin-group suggesting increased plaque stability. Immunohistochemistry revealed that MCP-1 was signifcantly less expressed (P<0.05) in the aortic root of canaglifozin-group while reduced expression of a-actin and CD68 was not reaching signifcance (P=0.15). VCAM-1 and MCP-1 mRNA levels were lower (P=0.02 and P=0.07, respectively), while TIMP-1/MMP-2 ratio expression was higher in canaglifozin-group approaching statistical signifcance (P=0.07). Conclusions: Canaglifozin attenuates the progression of atherosclerosis, reducing (1) hyperlipidemia and hyper‑ glycemia, and (2) infammatory process, by lowering the expression of infammatory molecules such as MCP-1 and VCAM-1. Moreover, canaglifozin was found to increase the atherosclerotic plaque stability via increasing TIMP-1/ MMP-2 ratio expression
