Show moreBackground and Significance: Caregiver vaccine hesitancy (VH) is a barrier to pediatric health. Current pediatric vaccination rates nationwide fall below the national recommendations. Understanding contributors to individualized hesitancy while employing motivational interviewing (MI) techniques can reduce caregiver hesitancy, improve influenza vaccination rates, decrease pediatric disparities, improve community health, and reduce healthcare costs. Purpose: The purpose of this quality improvement (QI) project was to reduce caregiver influenza vaccine hesitancy through provider education and the use of MI techniques with the MOTIVE-Flu (Motivational Interview Tool to Improve Vaccination Adherence) algorithm point of care tool. The intended outcome goal was to increase seasonal influenza vaccination rates by 10% when comparing the participating providers 2020 (without the intervention) to the 2021 (with the intervention) vaccination acceptance rate. Methods: A literature review guided the selection of the tools and techniques selected, which substantiated the effectiveness of MI within the pediatric population in the primary care setting. De-identified aggregate data was reviewed and provided by the organizational data manager and the participating Medical Assistant (MA). Statistical analysis was provided via Michigan State University (MSU). To assist with MI techniques and the MOTIVE-Flu tool use education was completed by the participating MA's, provider, and nurse practitioner student. Implementation: Implementation occurred from October 2021 to December 2021 within peak influenza vaccine administration season. The intervention occurred during all pediatric primary care visits for children aged six months through seventeen years. The Knowledge into Action Framework guided the development and monitoring process with bi-weekly clinical staff progress, evaluation, and support. Implications: Practical implications include reducing pediatric influenza morbidity and mortality, reducing the spread of influenza within the community, and decreasing healthcare costs.

Show moreBackground and Significance: According to the Institute of Medicine (IOM), medication-related errors lead to mortality and adverse effects such as allergic reactions, avoidable side effects, drug interactions, and unnecessary cost (IOM, 2000). Even with the predominant use of computerized provider order entry (CPOE) and clinical decision support systems (CDSS), medication discrepancies are still problematic today. There is substantial evidence available to demonstrate the benefits of using a transition of care (TOC) team for timely, appropriate medication reconciliation (MR) utilizing multiple intervention modalities. Purpose: This quality improvement (QI) project attempted to determine if the implementation of a TOC team utilizing a telephone-based MR system in a geriatric primary care setting improved identification of medication discrepancies and improved seven-day follow-up (FU) appointments following an inpatient admission. Methods: The TOC team at the geriatric primary care clinic was educated about the improved MR intervention tool and data collection process via a PowerPoint presentation. The data was collected via an Excel spreadsheet and analyzed for improvement upon identified medication errors and follow-through with timely FU appointments. The plan-do-study-act (PDSA) cycle was utilized for implementation. Results: A QI project was implemented in a geriatric primary care setting including 74 patients, 18 of which received the intervention. The implementation was carried out over a total of 12 weeks. Error identification increased from 0.71 errors per patient in the control group to 1.22 in the intervention group. Of the patients contacted via MR phone calls, 88.8% scheduled FU appointments; only 38.8% were within the goal time frame of seven days. The average time to FU during the implementation period was 9.1 days. Conclusion: The TOC team utilizing a telephonic MR improved identification of medication errors and overall FU rates. However, the TOC team did not positively impact the seven-day FU during MR from an inpatient hospitalization visit back to the outpatient setting. Results also indicated an improvement in the time spent per phone call. Keywords: care transition, transition of care team, medication reconciliation, seven-day follow-up, outpatient/ambulatory primary care.

Show moreBackground and Review of Literature: COVID-19 is a devastating illness that has detrimental health, financial and emotional consequences. Healthcare providers are utilizing questionnaires such as the PROMIS-29 form to help guide management of long term symptoms. Calling patients prior to their appointment as a reminder to complete their forms has proven to increase patient compliance with form completion. Purpose: The purpose of this quality improvement project was to increase the PROMIS-29 form response rate prior to the COVID-19 recovery care appointment, in hopes of improving care for patients living with post-COVID-19 conditions. Methods: This project was implemented at a large Midwest healthcare organization's primary care clinics. The Doctor of Nursing Practice (DNP) students called patients within 72 hours prior to their appointment, to remind them to complete the PROMIS-29 form on their MyChart portal. Implementation Plan/Procedure: The DNP students completed HIPAA training and utilized a script provided by the large Midwest healthcare organization when calling patients. A weekly report was provided by the community partner that includes a list of patients who needed to be called, according to the "post COVID follow up" visit type. The DNP students traveled to the large Midwest healthcare organization's administration building to conduct phone calls. Pre-intervention and post-intervention surveys were sent to the providers to determine the success of the intervention. Implications/Conclusion: Various project limitations impeded the ability to determine the success of the intervention however, the project proved helpful in determining that other reminder modalities may be of benefit to explore in the future.

Show moreBackground: Immunizations are often associated with pain and fear in the pediatric population. These negative emotions can have lasting effects on a patient's willingness to receive future medical care, including immunizations. Therefore, it is important to attempt to minimize the amount of pain and fear during all vaccination encounters. Purpose: A small West Michigan rural clinic had no formal process or tools for reducing pediatric pain during vaccinations. After an extensive literature review, it was decided to implement Buzzy®, a thermomechanical device, into the clinic's standardized practice for all pediatric immunizations. The goal was to improve the pediatric vaccination experience within the clinic. Methods: Using the PDSA model, two DNP students provided an in-service to the medical assistants on the use of the device. Education was also provided on the data collection tool that included an unvalidated survey assessing the parent/guardian's perception of their child's past and current vaccination experience, as well as the patient's pain level using one of three validated pain scales. Participants between the ages of 0-18 years and their parents/guardians had to be willing to use the Buzzy® device in order to enroll. Data was collected from October 2021 to January 2022. Results: Forty-five participants agreed to participate in this evidence-based practice (EBP) project. Participants' average pain score was mild with the use of Buzzy® at 2.9 out of 10. The average experience with Buzzy® was found to be significantly higher than the previous average vaccination encounter (p=.04). Finally, 95% of participants recommended continued use of Buzzy®. Conclusion: The implementation of Buzzy® during pediatric immunizations improved the immunization experience in a rural West Michigan clinic. These significant results support the continued use of Buzzy® at the clinic.

Show morePostoperative nausea and vomiting (PONV) is a significant concern in anesthesia practice. Evidence-based guidelines have sought to provide recommendations on identifying patients at risk for PONV and mitigating its effect with multimodal antiemetic strategies. An anesthesia department within a large teaching hospital uses the Anesthesiology Performance Improvement and Report Exchange guidelines to identify and manage patients at risk for PONV. These guidelines are intended to integrate best practices into anesthetic care and improve overall surgical outcomes. The anesthesia department currently has a PONV protocol in place that aligns with the guidelines but has not achieved their compliance benchmark. This evidence-based quality improvement project describes interventions proposed to increase compliance with the PONV protocol. To address poor PONV compliance, an anonymous survey was developed to assess anesthesia provider's current familiarity with the new PONV guidelines and identify misconceptions. A visual feedback system was implemented using a preliminary confidential list that anonymizes staff. This allowed individual providers to identify their own performance in relation to their peers in a non-punitive way. The results of this quality improvement project demonstrate that the proposed interventions increased departmental compliance.

Show moreThis evidenced-based practice initiative includes the development and implementation of an evidence-based enhanced recovery after surgery (ERAS) guideline with a specific focus on the incidence of postoperative nausea and vomiting (PONV) and opioid administration in the postoperative setting. The clinical question was in adult women, age 18 years or greater, undergoing a mastectomy procedure, does the implementation of an ERAS guideline lower the incidence of PONV and reduce morphine milligram equivalent (MME) requirements in a post-anesthesia care unit (PACU)? Patients undergoing breast cancer surgery have multiple risk factors and the reported incidence of PONV reaches up to 80%. Over half of post-surgical breast cancer patients develop neuropathic pain syndromes. A mastectomy ERAS guideline was developed then applied to the perioperative course of 22 patients. It was found that following an ERAS guideline reduced the incidence of PONV by 17% and reduced the average MME by 13.5 equivalents. Project implications include potential cost savings, reduced PACU length of stay, and improved patient outcomes.

Show moreBackground: Adults with type 2 diabetes mellitus (DM) have and continue to increase significantly within the United States (U.S.). The current recommended glycated hemoglobin A1c (HbA1c) goal for a nonpregnant healthy adult is a value of 7% to lower the risk of DM-related complications (American Diabetes Association [ADA], 2021). Because a goal of 7% may not be feasible in many cases due to other variables, each person with diabetes should have an individualized goal and treatment plan based on their health history and age (ADA, 2021). Compared to a lab draw, which can take hours to days before the provider can see the results, point of care testing (POCT) is more convenient because it produces results in minutes. Purpose: The goal of this quality improvement project was to enhance patient outcomes by introducing an algorithm to ensure that patients with diabetes were effectively managed according to the American Diabetes Association's current recommendations using POCT. Results: The data were subjected to Chi-square and T-tests, but no statistical significance was found. However, analysis of the data revealed many findings consistent with clinical significance. Conclusion: After analysis of the data from this quality improvement (QI) project, findings showed there was a positive correlation between POCT for HbA1c and an increase in values <9%. It was recommended staff continue to apply the algorithm to analyze the long-term outcomes of utilizing POCT for HbA1c in the family medicine clinic.

Show moreBackground and Review of Literature: Lack of advance care planning (ACP) leads to unwanted treatments and suffering for patients, along with increased healthcare costs. Certain vulnerable populations are at increased risk for unnecessary suffering, including those with high emergency department (ED) utilization rates and one-year prognoses. Providing ACP education to providers and utilization of the multidisciplinary team has been shown to increase ACP and advance directive (AD) rates in these vulnerable populations within primary care. Purpose: The purpose of this QI project was to increase the percentage of robust ACP conversations and the completion and documentation of ACP/ADs in the electronic medical record (EMR). Methods: The project was implemented at a primary care clinic in a midwestern Michigan community. DNP students attended an informational meeting regarding the organization's EMR-based ACP tool. An educational session regarding robust ACP was held for providers, a decision tree was developed to both guide ACP appointments with a specialist and ensure proper documentation into the EMR, and scripting was created to help guide ACP conversations. Implementation Plan/Procedure: Members of the multidisciplinary team utilized the intervention. Data collection included the percentage of empaneled patients with a durable power of attorney for healthcare (DPOAH) on file, the total number of robust ACP conversations completed, and the number of patients on the population health targeting list were collected. Post-intervention, an online survey was used to assess the provider's attitudes, knowledge, and confidence towards the decision tree. Implications/Conclusion: The intervention produced positive outcomes, which included an increase in completed and documented ACP/AD and provider knowledge regarding ACP.

Show moreIn chapter 1, I investigate how resource reallocation can affect the change of trade patterns and welfareeffect of trade. Specifically, trade liberalization can lead to a surge in the trade of intermediate goods. Increased accessibility to the critical intermediate goods through international trade can create an opportunity to initiate the expansion of capital-intensive industries, which can be referred to as specialization dynamics for developing countries. For this to occur, domestic resources must be reallocated toward high productivity sectors. In this paper, I capture the reallocation frictions in the labor market with sectoral wage differentials. A general equilibrium analysis explains the relationship between specialization dynamics and resource reallocation. I find that higher distortions in the skilled labor market negatively affect the productivity gain in the capital-intensive sector. This effect lowers overall welfare gains from trade for the countries with higher labor market distortions. In chapter 2, I improve the argument in chapter 1 by extending the model to dynamic structural model. Sluggish labor market response to trade liberalization can reduce the welfare gains from trade by impeding resource reallocation. I estimate sectoral labor switching costs for 30 countries in a dynamic discrete choice problem to derive welfare implications of labor market rigidity through comparative cross-country analysis. On average, workers have to give up approximately 4-years of income to switch to another sector. Compared with labor market flexibility measures, labor switching costs are low when the country has a flexible labor market and vice versa. In addition, I embed the switching cost estimates into a dynamic multi-country, multi-sector Eaton and Kortum model. In a counterfactual trade liberalization simulation with a 20% drop in trade costs, high switching costs lead to a slower response in the labor market, which in turn, negatively affect a country’s ability to achieve welfare gains from trade.

Show moreSex trafficking (ST) is a serious and hidden social problem affecting thousands of people in United States. ST is defined as “the recruitment, harboring, transportation, provision, or obtaining of a person for the purposes of a commercial sex act” or when that person “has not attained 18 years of age” (Trafficking Victims Protection Act, 2000). Given the violent, coercive, and economic tactics used to control victims of this crime, it is challenging for individuals to leave their trafficking situation. Thus, the purpose of this study was to understand how survivors exit from ST and use formal systems or services to facilitate that exit. This study presents findings from qualitative interviews with 34 survivors of domestic ST to understand the process of exiting the sex industry over time. Life History Calendar methodology was used to guide interviews about: 1) how participants conceptualized their experiences in the sex industry over time: 2) what formal systems participants had contact with during their time in the sex industry: and 3) the circumstances surrounding participants’ most recent exit from the sex industry. Results revealed that participants were in and out of ST multiple times over the course of their lives and had contact with many formal systems over time. However, what made the difference in most survivors’ last exit from the sex industry was the collaboration between formal systems to coordinate referrals and service provision. Findings from this study contribute to future research on exiting from sex trafficking and provide recommendations for policy and practice.

Show moreBacteria possess a wide range of metabolic pathways, allowing them to adapt to an array of environmental changes. Focusing on these different metabolic pathways allows us to observe how bacteria catabolize substrate or use anabolic pathways to generate biomass. A more in-depth look shows that many of these pathways are redundant, meaning a single organism can conduct the same overall reactions differing only by the types of enzymes or intermediates used. Overlapping pathways are common in bacteria and have become a focal point of metabolism research to determine the advantages of conserving redundant pathways throughout evolution. The metal reducing bacterium Shewanella oneidensis MR-1 is a practical model organism for metabolic studies, as it has substantial branching within its respiratory pathways. In this work, we focused on the extensive electron transport chain (ETC) of S. oneidensis MR-1 to understand the importance of seemingly redundant respiratory complexes and their functions during aerobic growth. The S. oneidensis MR-1 genome encodes four different NADH dehydrogenases (NDHs): a proton-pumping Type I NDH (Nuo), two sodium-pumping NDHs (Nqr1 and Nqr2), and one type II ‘uncoupling NDH (Ndh). NDHs oxidize NADH to move electrons into the ETC and generate ion-motive force that drives ATP synthesis, active transport, and motility. We determined that either Nuo or Nqr1 was required for aerobic growth in minimal medium. The presence of theoretically redundant complexes (Nqr2 and Ndh) did not rescue cell growth. Further, we determined that knocking out NDHs led to the inability to properly oxidize NADH. NADH build up inhibited the tricarboxylic acid cycle causing an amino acid synthesis defect and inhibiting growth of the S. oneidensis strain lacking Nuo and Nqr1. Recently, bacterial metabolic models have been developed to explain the use of energetically inefficient pathways during fast growth. Two standout models postulate that energetically inefficient pathways are used to reduce a cell’s proteome cost by eliminating thermodynamic barriers or to reduce dependence on the ETC as cells grow larger. We sought to uncover if these models applied to the respiratory chain of S. oneidensis MR-1 during aerobic growth, as the ETC can vary in energetic efficiency based on the combination of NDH and terminal oxidase used. Our findings indicate that the models apply to S. oneidensis MR-1 in the context of overflow metabolism during growth at higher growth rates, while the structuring of the ETC was not in agreement. Most importantly, determined that both carbon metabolism and the ETC were restructured for adaptive growth under differing conditions. As carbon metabolism became less efficient at faster growth rates, the NDH step of the ETC became more efficient, using complexes with higher coupling efficiencies.

Being a large contributor of CO2 emissions has made the power industry the focus of research efforts to develop post-combustion carbon capture technologies. This work represents a comprehensive examination of microalgal cultivation and biomass utilization as methods for post-combustion carbon capture and replacement of fossil-dependent technologies and products. Optimized pilot-scale cultivation represents a sustainable post-combustion carbon capture technology with downstream economic value. An initial study of a 100 L photobioreactor (PBR) within a 100 MW power plant was conducted to optimize the long-term, continuous cultivation of the green microalgae Chlorella sorokiniana. The culture utilized flue gas as a source of CO2 and successfully operated continuously over a year long period. Insights from this study include the growth kinetics of C. sorokiniana, optimal cultivation conditions of the PBR, and an in-depth analysis of the microbial-microalgal assemblage throughout the study. The biomass produced during the 12-month study was stored and subsequently utilized to develop methods for cell disruption and protein recovery. This work investigated a mechanochemical method, using ball milling technology and chemically induced pH changes, to efficiently extract and recover microalgal proteins. The results of this study indicate that the mechanochemical method requires less energy than existing mechanical methods, while achieving similar levels of cell disruption. In addition to protein extraction and recovery, an alternate pathway for biomass utilization was explored. Microalgal biomass and microalgal proteins contain the foundational building blocks required for synthesis of chemicals like polyols. Polyols, used for polyurethane (PU) foam production, represent another value-added product that could provide the economic incentive to invest in microalgal cultivation for post-combustion carbon capture. Using biomass and recovered proteins as feedstocks, polyols were synthesized using a one-pot, two step method. Two microalgal polyols were selected based on their characterization and were evaluated using life cycle and techno-economic frameworks. The results elucidated the environmental and economic advantages when using microalgal biomass as an alternative to petrochemicals as a feedstock for polyol synthesis. Finally, this work evaluated a combined biological and chemical post-combustion carbon capture system using microalgal cultivation and a novel microalgal amino acid salt solution (MAASS). Life cycle and techno-economic frameworks were used to compare the MAASS to a standard amine-based solvent. The results of these assessments show that the MAASS capture system performs significantly better than an amine capture system, both in terms of environmental impacts and the cost of capture. This comprehensive collection of data and analysis represents advances in the field, as well as innovative methods and technologies that further demonstrate the viability of microalgal cultivation and biomass utilization for carbon capture from the power industry.

Title: OCCUPATIONAL STRESS AMONG EMPLOYEES IN CRIMINAL-LEGAL SYSTEMS : A META-ANALYSIS
Creator: Lawson, Spencer Grant
Date: 2022
Collection: Electronic Theses & Dissertations
Description: Occupational stress is all too common, especially for employees in the criminal-legal system. Many sources of stress (i.e., stressors) have been shown to be associated with perceived occupational stress in the literature; yet, methodological variations and inconsistent findings across research articles obscure the empirical status of the effect of stressors on occupational stress among criminal-legal employees. To synthesize the research on this stressor-stress link, a meta-analysis was...
Show moreOccupational stress is all too common, especially for employees in the criminal-legal system. Many sources of stress (i.e., stressors) have been shown to be associated with perceived occupational stress in the literature; yet, methodological variations and inconsistent findings across research articles obscure the empirical status of the effect of stressors on occupational stress among criminal-legal employees. To synthesize the research on this stressor-stress link, a meta-analysis was conducted. Based on 80 peer-reviewed articles representing 57 unique data sets that contained 1,993 effect size estimates, random-effects analyses using multilevel modeling techniques were used to establish the grand mean effect of stressors on occupational stress. Results showed a modest effect of stressors on occupational stress (Mz = 0.15, 95% CI = [0.13, 0.18]). Importantly, the findings indicate that the strength of the effect size differed by the type of stressor. Specifically, larger effect sizes were yielded if the type of stressor was operational, followed by organizational stressors. The predicted effect size was smaller if the stressor was an individual demographic. Also, certain methodological decisions and study quality indicators moderate this effect. Overall, researchers must continue to explore the dimensions of these stressors to better understand their impact on occupational stress in criminal-legal systems. Theoretical, methodological, and practical implications of the meta-analytic findings are discussed and several directions for future research are identified in an effort to bring synergy to a disjointed evidence base.

Show moreRecent advances in sequencing and computation power have greatly contributed to our knowledge of plant genomics, and the development and use of plant genomic resources will be critical as plant researchers and breeders address future food security in light of the increasing world population, decreasing arable land, and variable effects of climate change. Plants belonging to the mint family provide culinary, medicinal, and cultural value due to their production of secondary metabolites. Genome assemblies and annotations for four important culinary herbs were generated to highlight genes involved in terpenoid biosynthetic pathways. Maize (Zea mays L.) is the most produced crop worldwide due in part to extensive commercial breeding programs. Genome assemblies and annotations for five commercially relevant maize inbred lines belonging to the stiff-stalk heterotic group were generated to characterize the pan-stiff-stalk gene repertoire and genomic regions associated with these founder lines. Tepary bean (Phaseolus acutifolius A. Gray), a close relative of the common bean (Phaseolus vulgaris L.), is indigenous to the arid climates of northern Mexico and produces high seed yields under drought stress. A diverse panel of tepary bean accessions was assembled, genotyped, and phenotyped to identify genomic regions associated with key agronomic traits that can be harnessed for tepary bean improvement.
