Clinical practice change: implementation of a pre-diabetic protocol
No full textPrediabetes is an expanding worldwide issue that requires more attention. It increases the patient’s risk for type 2 diabetes. Moreover, it increases other comorbidities, such as cardiovascular disease, due to increased insulin resistance. It is estimated that 85-90% of adults are unaware they have prediabetes. Screening could detect many undiagnosed prediabetes cases, suppressing the increasing trend of developing diabetes that needs treatment. Prediabetes can be reversed. Of those patients who progress to diabetes, an estimated 80% are diagnosed with obesity, which increases the patient’s mortality rate by 2.5-3 times in comparison to those who are not diagnosed with obesity. The American Diabetes Association recommends annual screening for those with prediabetes and high-risk individuals. The first-line approach to prediabetes is a reduced-calorie diet and routine moderate-vigorous exercise of 150 minutes weekly. This evidence-based project aimed to implement a pre-diabetic protocol to increase screening from 50% to at least 85% and decrease glycohemoglobin, weight, and waist circumference in adult patients 18 and older at risk of developing diabetes over 12 weeks. The evidence-based procedure was a clinical practice change implementing a pre-diabetic protocol to increase prediabetes screening at McLeod Primary Care Associates in Florence, South Carolina. It was estimated that 40% of the patients at this clinic have prediabetes. The evidence-based project promoted clinical practice guideline adherence to improve the quality of care. A pre-diabetic protocol will streamline practices with up-to-date research and prevent practice variations. The Diffusion of Innovations Theory (2010) provided the theoretical framework. The staff worked with 50 patients diagnosed with prediabetes with a glycohemoglobin of 5.7%-6.4% and who met the inclusion criteria. The Association of Diabetes Care and Education Specialists 7 Self-Care Behaviors lessons were followed for 12 weeks via Zoom; then, patients returned for a follow-up appointment. Pre- and post-implementation data were compared: Prediabetes risk tests demonstrated increased staff compliance with screening patients for prediabetes, a reduction in weight, waist circumference, and glycohemoglobin (glycemic control). The patients gained knowledge on prediabetes as evidenced by their increased post-test scores
Evaluating the accuracy of Johnson-Cook strain rate sensitivity for FCC aerospace structural materials
No full textUnderstanding aerospace materials’ strain rate sensitivity is crucial for accurate designs and analysis for structural performance in dynamic loading conditions, such as rocket launches, airplane collisions, and debris impacts. Three common aerospace face-centered cubic (FCC) metals are evaluated through various strain rate tests and FEA and simulation modeling. Quasi-static and intermediate tests are performed on a hydraulic load frame, and dynamic tests are run on a split-Hopkinson pressure bar, all in tensile motion. This covers the range of strain rates from 1x10-3 s-1 to 1x103 s-1. Results reveal little strain rate sensitivity at room temperature for A286 steel and AL7075 aluminum, while Inconel 718 clearly shows some variations. Finite Element Analysis (FEA) was run with LS-DYNA to simulate tabulated material models and Johnson-Cook constitutive models. Material constants are derived from experimental data, and the simulations are compared to the experimental results. Overall, the tabulated simulations show a more accurate comparison than the mathematical Johnson-Cook model. This research confirms that tabulated, data-derived material models are more accurate than empirical equations and recommends that for the design and analysis of dynamic aerospace structures, tabulated, or tabulated-based, simulations should be used. A full investigation of A286 steel is presented with experimental tests and simulation model results for analysis and conclusions. Future work includes completing the investigation of AL7075 and IN718

No full textImplementation of a nurse-led service to improve venous ulcer healing time and access
No full textVenous leg ulcerations (VLUs) commonly affect older adults, rural residents, and those with multiple health conditions, leading to high healthcare costs and significant physical and social challenges. The gap between demand for VLU management and available advanced practice providers (APPs) extends healing time and delays access to specialized care, increasing the risk of complications and patient dissatisfaction. This quality improvement project was designed to understand the effect of implementing a nurse-led service using the TIME tool and the Wound, Ostomy, Continence Nurses Association (WOCN) guidelines in VLUs healing time and time to access care over twelve weeks as compared to pre-intervention. A nurse-led intervention involves wound clinic nurses (WCN) being trained in wound assessment, treatment planning, and patient management under the supervision of a nurse practitioner. After teaching two WCNs the TIME tool and WOCN guidelines before the start of the project, WCNs delivered weekly care to VLU patients during the project implementation. Thirty-nine patients ages 50-65 with no concomitant peripheral arterial disease, type II diabetes, cognitive impairment, or rheumatological disorders such as mixed connective tissue disease immunocompromised were included in the intervention. The twelve-week timeline was chosen based on evidence that successfully utilized a nurse-led service. The wound was considered healed when the size was less than 1 cm2 or had 100% new skin tissue. For the pre-intervention group, the project lead extracted wound size at weeks 4, 8, and 12 and healing and access times for 16 newly referred patients who met inclusion criteria 12 weeks before the intervention. Fifty percent and 82% of patients had a wound healed at 12 weeks for pre-intervention and intervention groups (mean = 104.19 and 47.85 days), respectively (p \u3c .001). Furthermore, the pre-intervention access time to the wound clinic mean was 19.31 days, which was reduced to 7.68 days after intervention (p \u3c .001). A Friedman test indicated that the decrease in wound size was statistically significant across different periods within the intervention group. This QI project demonstrated positive results consistent with the literature, significantly reducing wound healing time and improving access to expert care with a nurse-led wound service
