Study Background: Researchers at ASU have determined that significant energy and environmental benefits are possible in the Phoenix metro area over the next 60 years from transit-oriented development along the current Valley Metro light rail line. The team evaluated infill densification outcomes when vacant lots and some dedicated surface parking lots are repurposed for residential development. Life cycle building (construction, use, and energy production) and transportation (manufacturing, operation, and energy production) changes were included and energy use and greenhouse gas emissions were evaluated in addition to the potential for respiratory impacts and smog formation. All light rail infill scenarios are compared against new single family home construction in outlying areas.
Overview of Results: In the most conservative scenario, the Phoenix area can place 2,200 homes near light rail and achieve 9-15% reductions in energy use and emissions. By allowing multi-family apartments to fill vacant lots, 12,000 new dwelling units can be infilled achieving a 28-42% reduction. When surface lots are developed in addition to vacant lots then multi-family apartment buildings around light rail can deliver 30-46% energy and environmental reductions. These reductions occur even after new trains are put into operation to meet the increased demand.
Better methods are necessary to fully account for anthropogenic impacts on ecosystems and the essential services provided by ecosystems that sustain human life. Current methods for assessing sustainability, such as life cycle assessment (LCA), typically focus on easily quantifiable indicators such as air emissions with no accounting for the essential ecosystem benefits that support human or industrial processes. For this reason, more comprehensive, transparent, and robust methods are necessary for holistic understanding of urban technosphere and ecosphere systems, including their interfaces. Incorporating ecosystem service indicators into LCA is an important step in spanning this knowledge gap.
For urban systems, many built environment processes have been investigated but need to be expanded with life cycle assessment for understanding ecosphere impacts. To pilot these new methods, a material inventory of the building infrastructure of Phoenix, Arizona can be coupled with LCA to gain perspective on the impacts assessment for built structures in Phoenix. This inventory will identify the origins of materials stocks, and the solid and air emissions waste associated with their raw material extraction, processing, and construction and identify key areas of future research necessary to fully account for ecosystem services in urban sustainability assessments. Based on this preliminary study, the ecosystem service impacts of metropolitan Phoenix stretch far beyond the county boundaries. A life cycle accounting of the Phoenix’s embedded building materials will inform policy and decision makers, assist with community education, and inform the urban sustainability community of consequences.
This study aims to quantify the environmental impacts of a hospital’s daily BMW disposal in the Phoenix, Arizona area. The sole option to dispose of BMW in Arizona is to sterilize the waste by sending it through an autoclave, and then dispose the sterilized waste in a landfill. This study used a Phoenix area hospital to create a start point for the waste and a general estimation of how much BMW the hospital disposes of. The system boundary for the LCA includes BMW generated at the Phoenix-area Hospital as it is travels to Stericycle, where it is autoclaved, and then transported to a landfill for disposal. The results of this retrospective, end-of-life LCA using this boundary enables hospital employees and policy makers to understand the environmental impact of placing items in the biohazardous waste bin.
Phoenix is the sixth most populated city in the United States and the 12th largest metropolitan area by population, with about 4.4 million people. As the region continues to grow, the demand for housing and jobs within the metropolitan area is projected to rise under uncertain climate conditions.
Undergraduate and graduate students from Engineering, Sustainability, and Urban Planning in ASU’s Urban Infrastructure Anatomy and Sustainable Development course evaluated the water, energy, and infrastructure changes that result from smart growth in Phoenix, Arizona. The Maricopa Association of Government's Sustainable Transportation and Land Use Integration Study identified a market for 485,000 residential dwelling units in the urban core. Household water and energy use changes, changes in infrastructure needs, and financial and economic savings are assessed along with associated energy use and greenhouse gas emissions.
The course project has produced data on sustainable development in Phoenix and the findings will be made available through ASU’s Urban Sustainability Lab.
Purpose: This project sought to evaluate the gap that exists between best practice and current practice, for sepsis identification and EGDT implementation.
Methods: The project was completed over a four-month period with prior Institutional Review Board (IRB) approval and consisted of evaluation of sepsis knowledge and barriers to EGDT. Questionnaires included demographics, sepsis knowledge, barriers to EGDT and AHRQ quality indicators toolkit.
Results: Sample (N=16) included registered nurses (RN) and healthcare providers. Descriptive statistics were utilized for evaluation of questionnaires. Results indicate staff have sound understanding of signs and symptoms of sepsis, however application through case studies demonstrated lower performance. Overall system barriers were minimal, with greatest barriers in central line monitoring and staff shortages. High level unit teamwork exists within the ED, however collaboration is lacking between ED staff and upper management. Results demonstrate moderate disengagement between upper management and staff leading to miscommunication. Recommendations included increased, consistent sepsis education, utilization of Institution for Healthcare Improvement (IHI) triple aim framework for evaluating systems, implementing a closed loop approach to communication, and having a staff champion for sepsis be included in meetings with upper management.
Children often present to the emergency department (ED) for treatment of abuse-related injuries. ED healthcare providers (HCPs) do not consistently screen children for physical abuse, which may allow abuse to go undetected and increases the risk for re-injury and death. ED HCPs frequently cite lack of knowledge or confidence in screening for and detecting child physical abuse.
The purpose of this evidence-based quality improvement project was to implement a comprehensive screening program that included ED HCP education on child physical abuse, a systematic screening protocol, and use of the validated Escape Instrument. After a 20-minute educational session, there was a significant increase in ED HCP knowledge and confidence scores for child physical abuse screening and recognition (p < .001). There was no difference in diagnostic coding of child physical abuse by ED HCPs when evaluating a 30-day period before and after implementation of the screening protocol.
In a follow-up survey, the Escape Instrument and educational session were the most reported screening facilitators, while transition to a new electronic health system was the most reported barrier. The results of this project support comprehensive ED screening programs as a method of improving HCP knowledge and confidence in screening for and recognizing child physical abuse. Future research should focus on the impact of screening on the diagnosis and treatment of child physical abuse. Efforts should also be made to standardize child abuse screening programs throughout all EDs, with the potential for spread to other settings.
