An increase in population and need to protect the planet has created many initiatives and research goals in developing alternatives methods of fueling. Federal and state policies have provided a push for industries to find ways to of reducing their impact on the environment while maintaining competitiveness. In the sector of alternative fuels, large policies such as the Renewable Fuel Standards (RFS) in the United States are making goals to reduce vehicular fuel from coal and oil, and focus on alternative fuels such as ethanol and biodiesel. Along with the RFS and other federal policies, states are introducing independent initiatives to promote the use of alternative fuels.

Research has shown that other crops besides corn can feasibly be used to produce ethanol for fuel use. One of the major crops of interest currently is switchgrass (Panicum Virgatum L.) because of its ability to grow under a variety of weather conditions and soil types. Switchgrass does not require as much maintenance as corn and is a perennial grass that can have high yielding fields for up to 9 years.

This report focuses on the impacts from using switchgrass-derived ethanol to meet the state of Arizona’s policy to have government fleet vehicles operating on alternative fuels. The study uses a life cycle assessment (LCA) approach to evaluate 22 million gallons of ethanol produced in Arizona and stored at fueling stations for use. Impacts in land use, global warming, and water quality are evaluated using software tools and databases in Ecoinvent and Simapro.

The results of the study indicate that the cultivation and harvest phase of the process will contribute the most to negative environmental impacts. According to the study, application of heavy nutrient fertilizer and the machinery needed for the additional agriculture have the potential to contribute over 36 million moles of hydrogen and 89 million CTU eq. to the air, soil, and water.

Falls are prevalent among those aged 65 years and older and may result in minor to debilitating injuries in this vulnerable population. Frailty, unsteady gait, and medication side effects all contribute to fall risk as well as dementia, a type of cognitive impairment that disrupts memory and judgment leading to an underestimation of fall risk. Fall prevention evidence suggests that interventions aimed at decreasing fall rates begin with a fall risk assessment and tailored fall prevention measures that promote safety.

To examine the effectiveness of a fall prevention program in dementia care, an evidence-based pilot was conducted in a long-term care facility focused on dementia care. A convenience sample of 16 nurses received a fall prevention education intervention. A fall prevention knowledge instrument measured pre and post-fall prevention knowledge. There was a significant increase in fall risk knowledge from the pre-test (p < .001). The participants then conducted a fall risk assessment of 50 dementia patients using the Morse Fall Scale.

Of the 50 dementia patients, 28 were identified as high risk for falls. The nurses then instituted tailored fall risk prevention measures for those high risk for falls. As a result of the pilot, 40 fall events were noted within a three-month time period, reflecting a significant reduction in falls (p < .001) from the previous year. The institution of a fall prevention program in dementia care incorporating nursing education, a fall risk scale, and measures to promote safety can reduce fall risk in dementia patients.

The coronavirus (COVID-19) pandemic led to disruptions in the food supply and high rates of unemployment and under-employment, both in Arizona and nationally. These emergencies required food assistance programs to adapt quickly and in unprecedented ways by relaxing eligibility criteria, improvising on delivery modalities, and increasing benefits. To examine food assistance program participation during the pandemic, we collected data from a representative sample of 620 Arizona households. The sample was drawn from across Arizona in July-August 2020 using an online survey. This brief provides the summary for participation in key food assistance programs, namely, the Supplementary Nutrition Assistance Program (SNAP), the Special Supplemental Program for Women Infants and Children (WIC), School Food Programs, and the emergency food assistance provided through food pantries.

Introduction: Pediatric delirium has a 25% prevalence rate in the pediatric intensive care unit (PICU). The project purpose was to implement a nonpharmacological nursing bundle in the PICU to assess the effects on delirium reduction.

Method: A nonpharmacological nursing bundle was implemented for PICU patients, 2-18 years of age, admitted to an Arizona metropolitan, children’s hospital. Data was collected using the Cornell Assessment of Pediatric Delirium (CAP-D) screening tool.

Results: Prebundle CAP-D and postbundle CAP-D scores (M=5.57, SD=5.78; M=7.10, SD=5.61) did not differ among the participants. Prebundle participants required an intervention 26.7% of the time for delirium compared to 31.6% in the postbundle population. No statistical significance was seen between the prebundle and the postbundle CAP-D scores t(59)=7.46; t(205)=18.17 (P=0.08, fisher’s exact test).

Discussion: Nonpharmacological bundles for delirium prevention are needed in the PICU. This project shows that significant barriers exist when implementing them in a complex pediatric environment.

With more than 19 million confirmed COVID-19 cases across the United States1 and over 500,000 in Arizona as of December 2020, the ongoing pandemic has had devastating impacts on local, national, and global economies. Prior to the pandemic (February 2020), based on U.S. Bureau of Labor Statistics data, the unemployment rate in Arizona was 6.5%, compared to 4.9% at the national level.3 Since the beginning of the COVID-19 pandemic (March 2020), the United States has experienced striking increases in the unemployment rate, reaching 13.2% in April. Similarly, in Arizona, the unemployment rate jumped to over 13.5% in April. The unemployment rates have since declined both nationally and in Arizona but remain higher compared to February 2020. In November 2020 (the most recent data available), the national unemployment rate was 6.7%, while in Arizona the rate was 7.8%—the 10th highest unemployment rate among all U.S. states.

Background and Aims: The aim of this research was to assess whether clients receiving treatment for substance abuse in a residential treatment facility will achieve lower rates of relapse with treatment in combination with active sponsorship. Prior studies suggest sponsorship may equally be impactful as attending 12-step meetings.

Design: The primary hypothesis was that active participation as defined by contact with a sponsor of an hour or more per week, as measured by the impact on affective characteristics correlated with increased levels of sobriety, when measured by the AWARE questionnaire (Advance Warning of Relapse) within 7 days of entry and prior to discharge (within 30 days). Setting: The project took place in a residential treatment facility in Phoenix, Arizona.

Participants: There were 12 clients from a men’s house and 12 clients from a woman’s house, all of which were going through recovery. Intervention: The educational session explained what a sponsor is and the importance of finding one early as a key role in relapse prevention.

Measurements: Pre and post-test results were compared to see if there was an impact on the predictability of relapse and sponsorship. The paired t-test was performed to compare the two means of AWARE scores. A lower score on the AWARE questionnaire indicates a person is more likely to succeed in sobriety.

Findings: Based on 24 samples collected, the mean scores within the first seven days were 91.17 with a standard deviation of 18.59 and the mean score prior to discharge were 72.78 with a standard deviation (SD) of 20.02. The mean difference between the two scores was 18.39 (SD=2.84). There was a significant effect of the relapse prevention program which included sponsorship, t (22) = 4.79, p < 0.001.

Conclusion: Implications for practice include increased time with sponsors to reduce rates of relapse. Future concerns include good fit matching which may reduce rates of relapse even further.

Purpose/Aims: We aim to increase understanding of water safety measures among primary care providers and improve the quality and efficiency of parent water-safety education.

Background and Significance: Drownings are the leading cause of death in one to four year old children in the United States. Arizona’s drowning rate is nearly double the national average for this age group. Water safety is an important anticipatory guidance topic a primary care provider should be discussing at all well visits. The Health Belief Model is an effective framework to guide family education interventions. It is strongly encouraged that providers incorporate water safety education into the developmental milestone discussions.

Methods: Ten providers recruited from six Arizona pediatric primary care clinics participated in an educational one-hour session. Providers were encouraged to prioritize water safety discussions within the one to four year old age group and deliver education in the context of individual child development. Additionally, providers were updated on water safety recommendations from the Center for Family Health and Safety at Phoenix Children’s Hospital. Supplemental handouts with developmental water safety information were given to each office to aid providers in parent education. A pre-survey was administered to the providers prior to the education session and a post-survey was given at an eight-week follow up. The surveys measured provider perception and current practices of water safety education and utilized a Likert scale to compare data sets. Current and retrospective chart reviews were conducted to evaluate sustainability of the educational intervention.

Outcomes/Results: Sixty percent of provider participants were Medical Doctors (MD) and 40% were Nurse Practitioners (NP) with experience ranging from one year to over 20 years. Following the education session, providers were more likely to discuss keeping a child at arms-reach at all times (p=0.046) during their well visits. There was also an increase in providers incorporating water safety discussions into milestone education (p=0.054).

Conclusion: This educational intervention empowered providers to deliver water safety education in the context of normal developmental milestones at each one to four year old well visit. The anticipatory guidance emphasizes to parents that the behaviors their children exhibit are healthy and normal, but also explains how achieving these milestones put their children at greater risk for drownings. This quality improvement project is part of a larger initiative to decrease the number of drownings in Arizona through education and policy

Purpose: The purpose of the project was to improve physical activity (PA), eating habits (EH) and self-efficacy (SE) by implementing short lifestyle modification education in a rural primary care setting.

Background: Although prediabetes awareness has slightly improved, the nationwide unawareness remains high. General knowledge about the disease and its risk factors and prevention are significant variables to adopt health-promoting behaviors. Lifestyle change intervention has been shown to be effective with the risk reduction behaviors in prediabetic population. However, it can be a daunting task to translate during short office visits.

Methods: Sixteen participants with risk for prediabetes or diagnosed prediabetes enrolled into a 5-minute education session in a rural health clinic. They received follow-up phone calls weekly for 4 weeks. Demographics, PA, EH and SE levels were measured before the education session. During the fourth week, PA, EH and SE were measured again. Frequency, descriptive analysis, and paired t-test were used for data analysis.

Outcomes: The mean age of participants was 56.6  13.0 years. Approximately 81% were female, and 62.5% identified as Caucasian. Over 80% reported married, and 56.3% described their health condition as good. The three quarters (75%) noted they have heard of the term prediabetes. The intervention had a significant effect on PA, EH and SE from the baseline to post intervention, p = .005, p = .008, and p = .003, respectively.

Conclusion: This DNP project illustrated that one time brief lifestyle change education could positively impact PA, EH and SE in people with high risk for prediabetes in a primary care clinic.
