This study investigates the relationship between the number and type of prototypes developed in rapid prototyping contexts, a team's performance self-estimations, and final actual performance. Findings suggest a strong correlation between each of these elements, with the converse also found to be true, motivating the introduction of the concept of Design Delusion - a type of cognitive dissonance due to differences between perceived and actual states. The paper suggests that early prototyping helps identify and mitigate design delusion, improving design decisions and preventing technical debt.

Development of large-scale quantum computing systems will require radio frequency (RF) and microwave technologies operating reliably at cryogenic temperatures down to tens of milli-Kelvin (mK). The quantum bits in the most promising quantum computing technologies such as the superconducting quantum computing are designed using principles of microwave engineering and operated using microwave signals. The control, readout, and coupling of qubits are implemented using a network of microwave components operating at various temperature stages. To ensure reliable operation of quantum computing systems, it is critical to ensure optimal performance of these microwave components and qubits at their respective operating temperatures, which can be as low as mK temperatures. It is, therefore, critical to understand the microwave characteristics of waveforms, components, circuits, networks, and systems at cryogenic temperatures. The UK’s National Physical Laboratory (NPL) is focussed on developing new microwave measurement capabilities through the UK’s National Quantum Technologies Programme to address various microwave test and measurement challenges in quantum computing. This includes the development of various measurement capabilities to characterize the microwave performance of quantum and microwave devices and substrate materials at cryogenic temperatures. This paper summarizes the roadmap of activities at NPL to address these microwave metrology challenges in quantum computing.

OBJECTIVES/GOALS: Studies to improve uptake of Chronic Obstructive Pulmonary Disease Clinical Practice Guidelines (COPD CPG) have yielded inconsistent results. We hypothesized that using implementation science would facilitate rigorous site ‘diagnosis’, and promote effective contextual tailoring of COPD CPG, while piloting the use of telehealth for this. METHODS/STUDY POPULATION: The study was conducted in two Veterans Affairs primary care clinics located in a small sized city. A detailed formative evaluation was conducted using key informant interviews (with VA staff and veterans with COPD who received care at this location) and quantitative data. Multidisciplinary stakeholder group was engaged and strategies to address the determinants identified through the previous step were identified. Telehealth was strongly encouraged as the primary modality for implementing the COPD CPG and we are collecting pilot data on this. Tele-Facilitation, used as the meta-strategy was employed in conjunction with other strategies such as develop/distribute educational materials, tailor strategies, change record systems and revise professional roles. RESULTS/ANTICIPATED RESULTS: Primary Care at the VA is provided by Patient Aligned Care Teams (PACT-teams), where each team consists of multiple health professionals to provide collaborative care to the patient. Discussions with the multidisciplinary stakeholder team suggested that any implementation effort primarily focused on physician and nursing efforts was unlikely to succeed due to competing demands. A pharmacy-centric model that allowed for the PACT-team clinical pharmacist to address most of the COPD CPG (inhaler technique education/assessment, inhaler choice optimization, COPD-specific patient education, spirometry use, smoking and immunization) was developed and implemented with incorporation of telehealth (video visits and telephone). We will present pilot implementation outcomes using RE-AIM framework elements. DISCUSSION/SIGNIFICANCE: This use of implementation science to implement COPD CPG and novel use of telehealth has enormous potential for impact. Increasing reach/adoption by targeting primary care practices can help permeate quality care to the underserved population. This data will allow us to explore generalizability through wider scale implementation studies.

OBJECTIVES/GOALS: To evaluate the incidence of brachial plexus birth injury (BPBI) and its associations with maternal demographic factors. Additionally, we sought to determine whether longitudinal changes in BPBI incidence differed by maternal demographics. METHODS/STUDY POPULATION: We conducted a retrospective cohort study of over 8 million maternal-infant pairs using California’s Office of Statewide Health Planning and Development Linked Birth Files from 1991-2012. Descriptive statistics were used to determine BPBI incidence and the prevalence of maternal demographic factors (race, ethnicity, age). Multivariable logistic regression was used to determine associations of year, maternal race, ethnicity, and age with BPBI. Excess population level risk associated with these characteristics was determined by calculating population attributable fractions. RESULTS/ANTICIPATED RESULTS: The incidence of BPBI between 1991-2012 was 1.28 per 1000 live births, with peak incidence of 1.84 per 1000 in 1998 and low of 0.9 per 1000 in 2008. Incidence varied by demographic group, with infants of Black (1.78 per 1000) and Hispanic (1.34 per 1000) mothers having the highest incidences. Controlling for relevant covariates, infants of Black (AOR=1.88, 95% CI 1.70, 2.08), Hispanic (AOR=1.25, 95% CI 1.18, 1.32) and advanced-age mothers (AOR=1.16, 95% CI 1.09, 1.25) were at increased risk. Disparities in risk experienced by Black, Hispanic, and advanced-age mothers contributed to a 5%, 10%, and 2% excess risk at the population level, respectively. Longitudinal trends in incidence did not vary among demographic groups. Population-level changes in maternal demographics did not explain changes in incidence over time. DISCUSSION/SIGNIFICANCE: Although BPBI incidence has decreased in California, demographic disparities exist. Infants of Black, Hispanic, and advanced-age mothers are at increased BPBI risk compared to White, Non-Hispanic, and younger mothers.

OBJECTIVES/GOALS: To evaluate the association of maternal delivery history with a brachial plexus birth injury (BPBI) risk in subsequent deliveries, and to estimate the effect of subsequent delivery method on BPBI risk. METHODS/STUDY POPULATION: We conducted a retrospective cohort study of all livebirth deliveries occurring in California-licensed hospitals from 1996-2012. The primary outcome was recurrent BPBI in a subsequent pregnancy. The exposure was prior delivery history (parity, shoulder dystocia in a previous delivery, or previously delivering an infant with BPBI). Multiple logistic regression was used to model adjusted associations of prior delivery history with BPBI in a subsequent pregnancy. The adjusted risk (AR) and adjusted risk difference (ARD) for BPBI between vaginal and cesarean delivery in subsequent pregnancies were determined, stratified by prior delivery history, and the number of cesarean deliveries needed to prevent one BPBI was determined. RESULTS/ANTICIPATED RESULTS: Of 6,286,324 infants delivered by 4,104,825 individuals, 7,762 (0.12%) were diagnosed with a BPBI. Higher parity was associated with a 5.7% decrease in BPBI risk with each subsequent delivery (aOR 0.94, 95%CI 0.92, 0.97). Previous shoulder dystocia or BPBI were associated with 5-fold (aOR=5.39, 95%CI 4.10, 7.08) and 17-fold increases (aOR=17.22, 95%CI 13.31, 22.27) in BPBI risk, respectively. Among individuals with a history of delivering an infant with a BPBI , cesarean delivery was associated with a 73.0% decrease in BPBI risk (aOR=0.27, 95%CI 0.13, 0.55), compared with an 87.9% decrease in BPBI risk (aOR=0.12, 95%CI 0.10, 0.15) in individuals without this history. Among individuals with a previous history of BPBI, 48.1 cesarean deliveries are needed to prevent one BPBI. DISCUSSION/SIGNIFICANCE: Parity, previous shoulder dystocia, and previously delivering a BPBI infant are associated with future BPBI risk. These factors are identifiable prenatally and can inform discussions with pregnant individuals regarding BPBI risk and planned mode of delivery.

It is increasingly realized today that Western modernity has not only promoted progressive ideals such as scientific thought, human rights and democratic political systems. Its history is also marked by a much darker side, one of brutal conquest, biological and cultural destruction, enslavement and exploitation of non-European peoples in the context of European colonialism. This dark side of Western modernity was legitimized by pro-colonial ideologies of property, war, civilization, progress and race. Such ideologies emerged in areas like jurisprudence and philosophy since the 16th century, often building on views from classical antiquity (Pagden 1995). They shaped academic paradigms such as ‘scientific racism’, colonial anthropology and Orientalism in the 19th and early 20th centuries, and in many ways continue to influence contemporary societies and their academic practices.

There are numerous challenges pertaining to epilepsy care across Ontario, including Epilepsy Monitoring Unit (EMU) bed pressures, surgical access and community supports. We sampled the current clinical, community and operational state of Ontario epilepsy centres and community epilepsy agencies post COVID-19 pandemic. A 44-item survey was distributed to all 11 district and regional adult and paediatric Ontario epilepsy centres. Qualitative responses were collected from community epilepsy agencies. Results revealed ongoing gaps in epilepsy care across Ontario, with EMU bed pressures and labour shortages being limiting factors. A clinical network advising the Ontario Ministry of Health will improve access to epilepsy care.
