Excessive Hospitalizations and Its Associated Economic Burden among People with Diabetes in the United States

AbstractObjectivesWe conducted this study to estimate the excessive hospital admission among people with diabetes and the associated economic burden in the USA.MethodsThe study was based on the 2005 Nationwide Inpatient Sample (NIS), a nationally representative probability sample conducted annually by the Agency of Health Research and Quality. Nearly 8 million records were sampled from over 1000 community hospitals in the 2005 NIS.ResultsExcluding childbirth-related admissions, the estimated US hospitalizations numbered approximately 30.8 million; individuals with diabetes accounted for over 6.4 million (20.9%) of these admissions. For every 1000 individuals without diabetes, with type 1 diabetes, and with type 2 diabetes, the numbers of hospitalizations were 89, 418, and 303, respectively. The rates of hospitalization increased greatly by the presence of diabetes for all age groups and sex. During 2005, the national bill of hospital charges and costs for individuals with diabetes exceeded US$171 billion and US$90 billion, respectively. If the prevalence of diabetes increases to 7.5% from 7.0%, the total number of hospitalizations made by individuals with diabetes will be 7.5 million in 2015.ConclusionsAlthough approximately 7% of the population had diabetes in the USA, nearly 20.9% of hospitalizations were made by individuals with this condition. Due to the excessive hospitalizations incurred by patients with diabetes, a small increase in the number of people with diabetes will amplify the number of hospitalizations. Health-care communities should anticipate this possible increased demand of hospitalizations and the associated economic burden

Tensile Properties of Inkjet 3D Printed Parts: Critical Process Parameters and Their Efficient Analysis

To design and optimize for capabilities of additive manufacturing processes it is also necessary to understand and model their variations in geometric and mechanical properties. In this paper, such variations of inkjet 3D printed parts are systematically investigated by analyzing parameters of the whole process, i.e. storage of the material, printing, testing, and storage of finished parts. The goal is to both understand the process and determine the parameters that lead to the best mechanical properties and the most accurate geometric properties. Using models based on this understanding, we can design and optimize parts, and fabricate and test them successfully, thus closing the loop. Since AM materials change rapidly and this process will have to be repeated, it is shown how to create a cost and time efficient experimental design with the one-factor-at-a-time and design of experiments methods, yielding high statistical accuracies for both main and interaction effects. The results show that the number of intersections between layers and nozzles along the load-direction has the strongest impact on the mechanical properties followed by the UV exposure time, which is investigated by part spacing, the position on the printing table and the expiry date of the material. Minor effects are found for the storage time and the surface roughness is not affected by any factor. Nozzle blockage, which leads to a smaller flow-rate of printing material, significantly affected the width and waviness of the printed product. Furthermore, the machine’s warm-up time is found to be an important factor

The Performance Puzzle: Understanding the Factors Influencing Alternative Dimensions and Views of Performance

There is a large literature on the determinants of organizational performance, and its multidimensional nature is well recognized. However, little research has examined how different organizational and environmental factors influence different stakeholders’ performance assessments of the same service. We address this gap by comparing the factors influencing performance evaluations by different constituencies of child care centers in Ohio. We operationalize performance using (1) regulatory violations documented during state licensing inspections, (2) satisfaction with the center’s quality reported by center directors, (3) satisfaction with the center’s quality reported by teachers, and (4) satisfaction with care quality reported by parents. Our findings suggest that different organizational and environmental factors are associated with the performance assessments of different constituencies. In addition, some of these constituency assessments appear to influence each other

Do Relationships Matter? Assessing the Association Between Relationship Design and Contractor Performance

Contracting relationships vary in the extent to which they are complete and involve formal contract specification as well as the extent to which they are based on strong relationships and rely on cooperation and trust. Where a contracting arrangement falls on these two continuums constitutes what this paper refers to as relationship design and is likely to impact contractor performance. We use data from a survey of child-care centers and Head Start agencies in Ohio to examine the association between the design of contracting relationships and contractor performance. Contractor performance is assessed in two ways: an objective measure of violations identified by government inspectors and a perceptual self-rated measure of performance reported by the contracted service providers. Measures of relationship design are constructed using multiple survey items and are included in multivariate regression analyses while controlling for a variety of organizational characteristics. Findings suggest that contracts involving stronger relationships are positively associated with child-care center performance, and more complete contracts are negatively associated with performance when performance is measured using contractor self-reports

Putting the Pieces Together: A Comprehensive Framework for Understanding the Decision to Contract Out and Contractor Performance

Contracting out is currently one of the most prevalent mechanisms of the privatization movement. Understanding its trends and rigorously analyzing its implications is an increasingly salient issue for public management research. This article builds a multi-stage theoretical framework addressing two broad research questions. The first is to identify the array of economic, political, organizational, and institutional factors that may impact a government agency\u27s decision to contract out. The second is to detail the various organizational and environmental factors influencing contractor performance. Particular attention is paid to effective contract monitoring and its relationship to contractor performance

Faith-Based Assumptions About Performance: Does Church Affiliation Matter for Service Quality and Access?

To date, the common rhetoric and assumptions on the performance of faith-based organizations (FBOs), ironically, appear to be faith based rather than empirically supported: There is a paucity of research evaluating the effectiveness of FBOs that uses sufficiently rigorous methods and multiple measures of organizational performance. This study seeks to inform the debate on the relative effectiveness of FBOs by comparing religiously affiliated and secular nonprofit nursing homes using two distinct but complementary measures of organizational performance: service quality and access for impoverished clients. Using nationally representative panel data on 11,877 church-affiliated and secular nonprofit nursing homes, this study examines the effect of ownership with several regression models. Overall, the findings fail to confirm the assumption that FBOs perform better than secular nonprofit organizations in the context of the nursing home industry. Isomorphic pressures and commercialization trends within the nursing home industry are discussed to help explain these findings

Closer Than “Arms Length”: Understanding the Factors Associated With Collaborative Contracting

This article focuses on collaborative relationships between contractors and government agencies and explores which contract characteristics, contractor traits, and environmental factors are associated with the development of such relationships. The study uses data from the Partnership Impact Research Project, a three-round longitudinal survey of over one hundred child care centers and Head Start agencies in Ohio. Our findings suggest that stronger collaborative contracting relationships are associated with greater contract specificity, better contractor service quality, and contractor affiliation with a larger organization. On the other hand, a contractor’s financial autonomy and nonprofit status are negatively related to collaborative relationship strength. We also find that a contractor’s internal management capacity is positively associated with the development of shared procedures governing contractual relationships
