Abstract:
Performance measures typically are used by transportation agencies to measure progress toward organizational goals. As cities have reoriented their transportation priorities toward people instead of cars and have put more emphasis on multimodal transportation options, relatively few studies have identified measures that capture the urban context and are sensitive to the multimodal nature of urban transportation systems. Moreover, some studies have focused only on the measures without fully considering the available resources needed to capture these measures and the limitations in data. This lack often hampers implementation of performance measures and prevents agencies from creating a sustainable and reliable performance measurement program. The research presented in this paper defined a data-driven framework for monitoring mobility performance for urban transportation systems through a case study in the District of Columbia, conducted as part of an overall study to understand better the state of the District's transportation system. The study identified multimodal measures that were repeatable and that were supported by readily available, attainable, and reliable data sources. Measures that were common and could be compared across modes were considered in the selection process. The initial list was then refined and prioritized according to the data inventory by considering the availability and quality of data sources. Twelve multimodal measures that can be supported by valid, usable, and reliable data sets are recommended in the final metric list for evaluating multimodal mobility in the District.

Abstract:
Urban China always plays important political role in contemporary Chinese history. Urban residents, especially in provincial capital cities, are better educated and live in political, economic and social centers in China. Their support is indispensable for the current government in China. Utilizing a large-scale survey data this study explores sources of subjective evaluation of local municipal government policy performance among Chinese urban residents in ten large Chinese cities. Descriptively, this study finds moderate satisfaction with city government performance among Chinese urbanites, which seems to lend support to Chinese government’s performance-based political legitimacy and explains relative political stability in China. Analytically, it is found that, while perceived public participation in municipal policy-making process, perceived government transparency, and personal life satisfaction increase Chinese urban residents’ positive evaluation of government performance, perceived official corruption, democratic orientation and level of political interest lead to negative evaluation of government performance among Chinese urbanites.

Full text
Abstract:
Urban VANET (Vehicular Ad hoc NETworks) performance optimization concerns the improvement of wireless signal quality between two arbitrary selected nodes moving within along city streets. It includes three procedures: VANET architecture modeling; wireless signal simulation; and signal quality optimization techniques. The first procedure converts real-world map data into a network graph according to the requirement of the optimization algorithm. The second step analyzes a communication route between two network nodes and calculates received signal quality with the information provided by the network model. The final operation optimizes the signal quality to an expected level by choosing appropriate communication route between two wireless nodes. In this thesis, three optimization techniques are presented: EP (Evolutionary Programming), SG (Stochastic Geometry) and SW (Small World). EP is a widely applied optimization strategy based on Darwin’s natural selection and evolution theory. It is effective with an enormous number of data support, and it can provide detailed route information. However, it requires enough time to evolve to an optimal solution. SG is a statistical tool to analyze points’ distribution within a multi-dimensional space, and it was recently applied on wireless network analysis. Given the distribution characteristics of an urban area, SG can calculate average data loss rate of a communication route. However, it cannot provide detailed route information. SW is a widely accepted model to represent people’s relationship in social networks, and it can be used in VANET analysis. SW provides a simplified network architecture compared with EP an SG. However, it requests additional long-range communication equipment and consumes more energy. The thesis is divided into three parts. Chapter 1 introduces the history of VANET and its architecture (in this research, it is a combination of Ad hoc network and WSN (Wireless Sensor Network)). Chapter 2 and 3 presents literature review of EP and SG. Chapter 4, 5, and 6 discusses how to implement EP, SG and SW on Boston VANET. At the end of each chapter, a conclusion is presented and a discussion on the author’s contribution is given.

This research is concerned with applying environmental urban performance analysis methods to comparative urban master planning. Using bottom-up physics-based urban simulation algorithms, the author established a repeatable methodology for computationally analyzing and comparing urban environments. Conditions simulated included, individual building operational energy use, floor-by-floor spatial daylight autonomy, and site wide occupant mobility. The study area is the Interstate 195 redevelopment site in Providence, Rhode Island. Four historic master planning documents were sampled from 1992 to 2012. The predominate instrument for geometric modeling and simulation was the MIT Urban Modeling Interface(UMI). The methodology proposed in this study provides both, a specific framework of values for performance optimization in Providence as well as a more general framework for the automation of urban simulations in disparate regions. Results from this experiment were processed using custom instrumentation, built using web-based network architecture, to provide rapid result visualization and interactive urban data display. The research concludes by proposing a new architecture of urban system modeling.

Abstract:
Solar radiation is energy, a natural and inexhaustible source of heat and light, and as such a major factor to be considered for enhancing urban environmental sustainability. Solar availability on buildings determines to a large degree their active and passive solar potential; whereas, the insolation of open spaces affects their microclimate and in turn, their use and liveability. Solar objectives are thus multiple and may also be conflicting in time and space, especially in temperate climates, where thermal comfort needs vary in seasons. The subject of the thesis is the relationship between urban geometry and environmental performance of urban forms, explored at the neighbourhood scale and in real urban areas. Specifically, the research investigates statistically casual relationships of urban geometry with environmental phenomena related, directly or indirectly, to the availability of solar radiation. Full consideration is given to the varying solar geometry as a major parameter affecting the interaction between urban geometry and solar radiation, lending it a temporal and geographical -related to latitude- character. The research subject is explored through three distinct studies, which share the same methodology investigating particular topics under the same thematic umbrella. The first and the third study, in the order of these being presented, investigate phenomena occurring in open spaces, namely insolation and thermal diversity; whereas, the second study examines solar availability in open spaces and on building façades. In the methodology, urban geometry is distinguished into built density, which is associated negatively with solar availability but positively with sustainability at the city-scale, and urban layout. The former expresses total built volume in a site, and the latter is represented by a set of quantified geometric parameters which characterise the way in which the built volume is allocated and distributed within the site. This distinction aims to provide evidence for the significance of urban layout in modifying the solar urban environment as well as addressing conflicting solar design objectives. The performance of the urban forms is examined through a series of performance indicators, namely sky view factor, insolation, solar irradiance and thermal diversity values. Both urban geometry variables and performance indicators are calculated on average in each urban form. The great size of the sample analysed allows their relationships to be investigated in statistical means. The research belongs to the new era of urban environmental studies which make use of digital 3D models of cities to study spatially expressed phenomena in the built environment. It is based entirely on the analysis of existing urban forms, of 500x500m area, found in two European cities, London and Paris. London constitutes the main case study city, whereas Paris is examined for comparison purposes. The two cities are located at similar geographical latitudes and within the same climatic context, but their urban fabrics exemplify very different geometries. The geometric and environmental analysis of the urban forms as well as the elaboration and processing of the output data are performed using computer-based tools and methods, such as MATLAB software and image processing techniques applied in urban digital elevation models (DEMs) and, SOLWEIG and the RADIANCE-based software, PPF, for SVF and solar simulations. The research findings contribute to the field of urban environmental studies and design at multiple levels, presenting a significant theoretical, practical, and methodological value. First, they produce a critical insight about the factors affecting the relationship of urban geometry and sun-related phenomena occurring in the urban environment and lending it a dynamic character. In addition, they provide solid evidence about the enormous potential of urban geometry for promoting multiple -and sometimes conflicting- solar and urban design objectives, informing the relevant on-going discourse. Third, having as case studies real forms in London and Paris, a part of the findings is interpreted into urban design guidelines for enhancing the environmental performance of new and existing areas in the two cities. Last, as the research employs new methods and techniques to explore diverse topics, some of which are relatively new in the literature, it constitutes an important, methodological precedent for future research works.

Abstract:
The planning, construction, management and use of our built environment are affected by diverse social, economic and environmental factors. Sustainable urban development is dependent on the understanding of the complex relations between the built environment, the social activities that take place over time and the interaction with the natural environment. The challenge to understand urban systems on both the local and global scale has inspired researchers and national agencies to develop sustainability indicators to support the planning, construction, management and use of the built environment. Access to open data of our built environment in national, regional and local databases opens new possibilities to generate models of our urban systems to facilitate visualization and analysis of indicators in order to enhance awareness of sustainability dimensions. Here spatial Extract, Transform and Load (ETL) technologies can be used in combination with Geographic Information system GIS to manage data sets from multiple sources in different formats. The purpose of this research is to investigate how spatial ETL technologies can be used to develop models in order to analyse and visualize the performance of urban systems. The applied method is grounded in system development and based on an abductive research approach that was repeated in six studies. Three of the studies deal with the relocation of Kiruna where models of the city was created and used to investigate the impact of mining subsidence on energy supply, infrastructure and buildings. The fourth case investigates the selection of insulation material on the embedded energy in a passive house in Kiruna. In the fifth case an urban model of the twin towns Malmberget/Gällivare was created to explore and relate data on attitudes from a survey to public data on population, infrastructure and built environment. The final case is the development of an energy atlas containing 90% of the multifamily building stock in Sweden. The atlas combines the energy performance and renovation status of multifamily buildings with public data of ownership, income of residents etc. for individual buildings in 3D models or aggregated on spatial scales ranging from 250x250 m squares through district and municipality to county areas in Sweden. The result shows that multiple sources in different formats, both standardized and non-standardized, can be utilized in the extraction of information for the purpose of developing urban performance models. The Swedish high-resolution LiDAR digital height model together property information makes it possible to represent the built environment by extruded footprints to give a 3D representation of all urban areas in Sweden (Level-Of-Detail 1). In combination with performance data (e.g. energy use, renovation status or result from surveys) urban performance GIS models can be created and visualized in applications (such as Google Earth, 3D pdf) to support decision-making on both individual and institutional level. The automation of the process to develop performance models offers a method for customizing information deliveries on the fly using original data sources according to defined requirements. The flexibility and customization are kept in the process rather than in the delivered model. This makes it easier to keep the performance model up to date. For the management of large performance models, e.g. the example of the national energy atlas, a staging phase was added in the automation process, in order to reduce the processing time.

Abstract:
This thesis contributes to discourses concerned with urban space and performance practice. It identifies ways in which built environments become performative; how the built environment performs meaning(s) within the urban context and how spatial practices of contemporary performance engage with city-spaces. The programming and order of urban space tends to fix meanings; increasingly regulated and singlepurpose city-spaces seem unable to react to informal or unplanned activities. However, this thesis suggests that urban space entails inherent opportunities for conceiving and practising space otherwise and looks at a spatial spectrum – from leftover spaces to London’s landmarks. It analyses incomplete presences in the built environment and their unexpected (re)uses, which make urban space an arena of ideas, interaction and creativity. It examines how spatial practices of performance, such as site-specific performance, audio-walks and installations, inform our (re)thinking of space, its meaning and its re-appropriation. It argues that through performative concepts and actions, space manifests a changeable and dynamic quality, rather than motionlessness and inertia. The thesis involves an interdisciplinary approach employing geography, urban, architectural and performance studies. It looks at four types of built spaces that have been used for performance purposes; a disused warehouse at 21 Wapping Lane, the converted power station housing the Tate Modern art gallery, the exterior of the National Theatre’s building and the London district of Wapping. All of these sites are awaiting, or are undergoing, major alterations in their design or planning, involving reconstruction and expansion, or total demolition. The uncertain future of these sites and buildings, the inevitable decay of their material, and the temporality of the built environment invite questions of architectural design and urban planning in terms of performance. The examination of these sites at this moment of change and the potential impact of the redevelopment plans on city life make this research timely, since the thesis emphasises the imperative of re-defining concepts of space, planning strategies, and design processes so as to imagine a less determinate, more creative urban space.

This thesis addresses the issue of energy efficiency through the lens of thermal performance in the context of urban housing in the city of Boston. Located in the historic brick row house neighborhood of the South End, the project utilizes brick for its inherent property of high heat capacity - a material's ability to store radiant energy and release it later due to the temperature difference between day and night - as a thermal battery for heating and cooling domestic spaces. In Boston where the temperature frequently goes below freezing in winter time, this thesis challenges existing housing typologies by incorporating thermal mass as a passive solar strategy at the scale of an entire structure. The urban solarium produces an interstitial zone in housing that promotes a new lifestyle by bringing together thermal performance and urban farming.

Abstract:
Time synchronization is critical for the operation of radio base stations (RBS) in telecommunication companies. Global navigation satellite system (GNSS) is an existing technology to provide precise timing information to distributed RBSs. GNSS timing receiver is used for providing higher timing accuracy than normal GNSS receiver in this synchronization domain.In this thesis, an experiment method for GNSS timing receiver performance in urban canyon has been designed and implemented to evaluate information and the quality of the one pulse per second (1PPS) signal generated by two different GNSS timing receivers. Multi-path signals and the gathered satellite geometry caused by poor sky visibility is identified as the main influential factors to the performance of the GNSS timing receivers. A mathematical model has been built for estimating the multi-path effect. GNSS planning tools are used to simulate the number of line-of-sight (LOS) satellites and Dilution of Precision (DOP) value.Sentinel is a 1PPS signal analyzing equipment from Calnex. Sentinel has an embedded rubidium clock, GNSS antenna, and receiver, and it can produce 1PPS signals to be used as a reference. In this report, we installed our GNSS antenna of Sentinel on the roof and test GNSS antenna in two specified positions representing urban canyon and rooftop. Recorded NMEA messages from GNSS receiver can help us to study the number of visible satellites, PDOP value and multi-path signals in realistic situations.The results show how the noise and time phase of 1PPS signals will be influenced in urban canyons. Since, the geometry of used satellites is similar to the rooftop situation, the multi-path effect of signals is identified as the main reason of this difference.This information is useful when telecommunication companies want to install their radio base station in urban canyons. It will help Ericsson to understand how their GNSS timing receiver is working and how the urban canyon will influence its performance.
Tidssynkronisering är kritisk för driften av radiobasstationer (RBS) i telekommunikationsföretag. Global Navigation Satellite System (GNSS) är en befintlig teknik för att ge exakt tidsinformation till distribuerade basstationer. GNSS-baserade tidsmottagare används för att ge högre timing-noggrannhet än vanlig GNSS mottagare i denna synkroniseringsdomän. I denna avhandling har en experimentmetod för GNSS-timingmottagarnas prestanda i urban canyon utformats och implementerats för att utvärdera den genererade informationen och kvaliteten på en puls per sekund-signal (1PPS). Flervägssignaler och den samlade satellitgeometrin som orsakas av dålig himmelsynlighet identifieras som de mest inflytelserika faktorerna för GNSS-tidsmottagarnas prestanda. En matematisk modell har donstruerats för att estimera multi-path-effekten. GNSS-planeringsverktyg används för att simulera antalet LOS-satelliter och DOP-värde (Dilution of Precision). Sentinel är en 1PPS signalanalysutrustning från Calnex. Sentinel har en inbyggd rubidiumklocka, GNSS-antenn och mottagare, och den kan producera 1PPS-signaler som ska användas som referens. I den här rapporten installerade vi vår GNSS-antenn på Sentinel på taket och GNSS-testantennen i två angivna positioner som representerar urban canyon och tak. Inspelade NMEA-meddelanden från GNSS-mottagare kan hjälpa oss att studera antalet synliga satelliter, PDOP-värde och flervägssignaler i realistiska scenarier. Resultatet visar att ljud- och tidsfasen för 1PPS-signaler påverkas i urban canyons. Eftersom satellitgeometrin liknar den för antenner placerade på taket, så är identifieras flervägsutbredningen som huvudorsak för denna skillnad. Denna information är användbar när telekommunikationsföretag vill installera sina radiobasstationer i urban canyons. Det kommer att hjälpa Ericsson att förstå hur deras GNSS-timingmottagare arbetar och hur urban canyon påverkar dess prestanda.

Full text
Abstract:
The rapid growth in population and related demand for travel during the past few decades has had a catalytic effect on traffic congestion, air quality, and safety in many urban areas. Transportation managers and planners have planned for new facilities to cater to the needs of users of alternative modes of transportation (e.g., public transportation, walking, and bicycling) over the next decade. However, there are no widely accepted methods, nor there is enough evidence to justify whether such plans are instrumental in improving mobility of the transportation system. Therefore, this project researches the operational performance of urban roads with heterogeneous traffic conditions to improve the mobility and reliability of people and goods. A 4-mile stretch of the Blue Line light rail transit (LRT) extension, which connects Old Concord Rd and the University of North Carolina at Charlotte’s main campus on N Tryon St in Charlotte, North Carolina, was considered for travel time reliability analysis. The influence of crosswalks, sidewalks, trails, greenways, on-street bicycle lanes, bus/LRT routes and stops/stations, and street network characteristics on travel time reliability were comprehensively considered from a multimodal perspective. Likewise, a 2.5-mile-long section of the Blue Line LRT extension, which connects University City Blvd and Mallard Creek Church Rd on N Tryon St in Charlotte, North Carolina, was considered for simulation-based operational analysis. Vissim traffic simulation software was used to compute and compare delay, queue length, and maximum queue length at nine intersections to evaluate the influence of vehicles, LRT, pedestrians, and bicyclists, individually and/or combined. The statistical significance of variations in travel time reliability were particularly less in the case of links on N Tryon St with the Blue Line LRT extension. However, a decrease in travel time reliability on some links was observed on the parallel route (I-85) and cross-streets. While a decrease in vehicle delay on northbound and southbound approaches of N Tryon St was observed in most cases after the LRT is in operation, the cross-streets of N Tryon St incurred a relatively higher increase in delay after the LRT is in operation. The current pedestrian and bicycling activity levels seemed insignificant to have an influence on vehicle delay at intersections. The methodological approaches from this research can be used to assess the performance of a transportation facility and identify remedial solutions from a multimodal perspective.

Full text
Abstract:
Trucks serve significant amount of freight tonnage and are more susceptible to complex interactions with other vehicles in a traffic stream. While traffic congestion continues to be a significant ‘highway’ problem, delays in truck travel result in loss of revenue to the trucking companies. There is a significant research on the traffic congestion mitigation, but a very few studies focused on data exclusive to trucks. This research is aimed at a regional-level analysis of truck travel time data to identify roads for improving mobility and reducing congestion for truck traffic. The objectives of the research are to compute and evaluate the truck travel time performance measures (by time of the day and day of the week) and use selected truck travel time performance measures to examine their correlation with on-network and off-network characteristics. Truck travel time data for the year 2019 were obtained and processed at the link level for Mecklenburg County, Wake County, and Buncombe County, NC. Various truck travel time performance measures were computed by time of the day and day of the week. Pearson correlation coefficient analysis was performed to select the average travel time (ATT), planning time index (PTI), travel time index (TTI), and buffer time index (BTI) for further analysis. On-network characteristics such as the speed limit, reference speed, annual average daily traffic (AADT), and the number of through lanes were extracted for each link. Similarly, off-network characteristics such as land use and demographic data in the near vicinity of each selected link were captured using 0.25 miles and 0.50 miles as buffer widths. The relationships between the selected truck travel time performance measures and on-network and off-network characteristics were then analyzed using Pearson correlation coefficient analysis. The results indicate that urban areas, high-volume roads, and principal arterial roads are positively correlated with the truck travel time performance measures. Further, the presence of agricultural, light commercial, heavy commercial, light industrial, single-family residential, multi-family residential, office, transportation, and medical land uses increase the truck travel time performance measures (decrease the operational performance). The methodological approach and findings can be used in identifying potential areas to serve as truck priority zones and for planning decentralized delivery locations.

Evaluation of automated feature extraction algorithms using high-resolution satellite imagery across a rural-urban gradient in two unique cities in developing countries. Engineer Research and Development Center (U.S.), April 2021. http://dx.doi.org/10.21079/11681/40182.

Abstract:
Feature extraction algorithms are routinely leveraged to extract building footprints and road networks into vector format. When used in conjunction with high resolution remotely sensed imagery, machine learning enables the automation of such feature extraction workflows. However, many of the feature extraction algorithms currently available have not been thoroughly evaluated in a scientific manner within complex terrain such as the cities of developing countries. This report details the performance of three automated feature extraction (AFE) datasets: Ecopia, Tier 1, and Tier 2, at extracting building footprints and roads from high resolution satellite imagery as compared to manual digitization of the same areas. To avoid environmental bias, this assessment was done in two different regions of the world: Maracay, Venezuela and Niamey, Niger. High, medium, and low urban density sites are compared between regions. We quantify the accuracy of the data and time needed to correct the three AFE datasets against hand digitized reference data across ninety tiles in each city, selected by stratified random sampling. Within each tile, the reference data was compared against the three AFE datasets, both before and after analyst editing, using the accuracy assessment metrics of Intersection over Union and F1 Score for buildings and roads, as well as Average Path Length Similarity (APLS) to measure road network connectivity. It was found that of the three AFE tested, the Ecopia data most frequently outperformed the other AFE in accuracy and reduced the time needed for editing.

Hoinkes, Ulrich. Indexicality and Enregisterment as Theoretical Approaches to the Sociolinguistic Analysis of Romance Languages. Universitatsbibliothek Kiel, November 2019. http://dx.doi.org/10.21941/hoinkesindexenregromlang.

Full text
Abstract:
Social indexicality and enregisterment are basic notions of a theoretical model elaborated in the United States, the aim of which is to describe the relationship between the use of language variation and patterns of social behavior at the level of formal classification. This analytical approach is characterized by focusing on the interrelation of social performance and language awareness. In my contribution, I want to show how this modern methodology can give new impetus to the study of today’s problem areas in Europe, such as migration and language or urban life and language use. In particular, I am interested in the case of Catalan, which has been studied for some time by proponents of the North American enregisterment theory. This leads me to indicate that explicit forms of social conduct, such as language shift or the emblematic use of linguistic forms, can be interpreted with regard to the social indexicality of Catalan. I thus analyze them in a way which shows that authenticity and integration in Catalan society can be achieved to a considerable extent by practicing forms of linguistic enregisterment.

Abstract:
The Signal Physics Representation in Uncertain and Complex Environments (SPRUCE) work unit, part of the U.S. Army Engineer Research and Development Center (ERDC) Army Terrestrial-Environmental Modeling and Intelligence System (ARTEMIS) work package, focused on the creation of a suite of three-dimensional (3D) signal and sensor performance modeling capabilities that realistically capture propagation physics in urban, mountainous, forested, and other complex terrain environments. This report describes many of the developed technical capabilities. Particular highlights are (1) creation of a Java environmental data abstraction layer for 3D representation of the atmosphere and inhomogeneous terrain that ingests data from many common weather forecast models and terrain data formats, (2) extensions to the Environmental Awareness for Sensor and Emitter Employment (EASEE) software to enable 3D signal propagation modeling, (3) modeling of transmitter and receiver directivity functions in 3D including rotations of the transmitter and receiver platforms, (4) an Extensible Markup Language/JavaScript Object Notation (XML/JSON) interface to facilitate deployment of web services, (5) signal feature definitions and other support for infrasound modeling and for radio-frequency (RF) modeling in the very high frequency (VHF), ultra-high frequency (UHF), and super-high frequency (SHF) frequency ranges, and (6) probabilistic calculations for line-of-sight in complex terrain and vegetation.

Full text
Abstract:
The coordination of transportation and land use (also known as “smart growth”) has been a long-standing goal for planning and engineering professionals, but to this day it remains an elusive concept to realize. Leaving us with this central question -- how can we best achieve transportation and land use coordination at the corridor level? In response, this report provides a review of literature and practice related to sustainability, livability, and equity (SLE) with a focus on corridor-level planning. Using Caltrans’ Corridor Planning Process Guide and Smart Mobility Framework as guideposts, this report also reviews various principles, performance measures, and place typology frameworks, along with current mapping and planning support tools (PSTs). The aim being to serve as a guidebook that agency staff can use for reference, synergizing planning insights from various data sources that had not previously been brought together in a practical frame. With this knowledge and understanding, a key section provides a discussion of tools and metrics and how they can be used in corridor planning. For illustration purposes, this report uses the Smart Mobility Calculator (https://smartmobilitycalculator. netlify.app/), a novel online tool designed to make key data easily available for all stakeholders to make better decisions. For more information on this tool, see https://transweb.sjsu.edu/research/1899-Smart-Growth-Equity-Framework-Tool. The Smart Mobility Calculator is unique in that it incorporates statewide datasets on urban quality and livability which are then communicated through a straightforward visualization planners can readily use. Core sections of this report cover the framework and concepts upon which the Smart Mobility Calculator is built and provides examples of its functionality and implementation capabilities. The Calculator is designed to complement policies to help a variety of agencies (MPOs, DOTs, and local land use authorities) achieve coordination and balance between transportation and land use at the corridor level.

Abstract:
30 Day Hospital Readmission Rates, Frequencies, and Heart Failure Classification for Patients with Heart Failure Background Congestive heart failure (CHF) is the leading cause of mortality, morbidity, and disability worldwide among patients. Both the incidence and the prevalence of heart failure are age dependent and are relatively common in individuals 40 years of age and older. CHF is one of the leading causes of inpatient hospitalization readmission in the United States, with readmission rates remaining above the 20% goal within 30 days. The Center for Medicare and Medicaid Services imposes a 3% reimbursement penalty for excessive readmissions including those who are readmitted within 30 days from prior hospitalization for heart failure. Hospitals risk losing millions of dollars due to poor performance. A reduction in CHF readmission rates not only improves healthcare system expenditures, but also patients’ mortality, morbidity, and quality of life. Purpose The purpose of this DNP project is to determine the 30-day hospital readmission rates, frequencies, and heart failure classification for patients with heart failure. Specific aims include comparing computed annual re-admission rates with national average, determine the number of multiple 30-day re-admissions, provide descriptive data for demographic variables, and correlate age and heart failure classification with the number of multiple re-admissions. Methods A retrospective chart review was used to collect hospital admission and study data. The setting occurred in an urban hospital in Memphis, TN. The study was reviewed by the UTHSC Internal Review Board and deemed exempt. The electronic medical records were queried from July 1, 2019 through December 31, 2019 for heart failure ICD-10 codes beginning with the prefix 150 and a report was generated. Data was cleaned such that each patient admitted had only one heart failure ICD-10 code. The total number of heart failure admissions was computed and compared to national average. Using age ranges 40-80, the number of patients re-admitted withing 30 days was computed and descriptive and inferential statistics were computed using Microsoft Excel and R. Results A total of 3524 patients were admitted for heart failure within the six-month time frame. Of those, 297 were re-admitted within 30 days for heart failure exacerbation (8.39%). An annual estimate was computed (16.86%), well below the national average (21%). Of those re-admitted within 30 days, 50 were re-admitted on multiple occasions sequentially, ranging from 2-8 re-admissions. The median age was 60 and 60% male. Due to the skewed distribution (most re-admitted twice), nonparametric statistics were used for correlation. While graphic display of charts suggested a trend for most multiple re-admissions due to diastolic dysfunction and least number due to systolic heart failure, there was no statistically significant correlation between age and number or multiple re-admissions (Spearman rank, p = 0.6208) or number of multiple re-admissions and heart failure classification (Kruskal Wallis, p =0.2553).
