Prehospital blood transfusion : Opportunities and challenges for the German emergency medical services

Exsanguination is the leading cause of preventable death in severe trauma. Immediate hemorrhage control and transfusion of blood products are critical to maintain oxygen delivery and address trauma-induced coagulopathy. While prehospital blood product transfusion (PHBT) is established in neighboring countries, the fragmented configuration of Germany's emergency medical service (EMS) infrastructure has delayed the adoption of widespread PHBT programmes. This review aims to provide an updated perspective on the evolution, international practices and research needs of PHBT within the German context. This narrative review is based on aPubMed search using the search terms "prehospital" and "blood*". From an initial 4738 articles, 333 were directly related to PHBT and were subjected to further detailed examination. The literature, including referenced studies, was categorized into areas such as history, rationale, international practices, and evidence, and analyzed for quality. The benefit of early blood transfusion in major trauma has been established since WW1, explaining the efforts to initiate this lifesaving intervention as early as possible in the care pathway, including the prehospital field. Recent randomized trials have faced design and recruitment challenges, reflecting the complexity of the research question. These trials have yielded inconclusive results regarding the survival benefits of PHBT in civilian settings. This scenario raises doubts about the capability of randomized trials to resolve questions concerning survival advantages. Despite these difficulties, there is adiscernible trend indicating potential improvements in patient outcomes. In Germany, the incidence of trauma-associated shock stands at 38per 100,000 individuals per year. It is estimated that between 300 and 1800 patients annually possibly benefit from PHBT. Prehospital Blood Transfusion appears to be promising but identifying patient groups most likely to benefit as well as the most suitable blood products remain unresolved issues. In Germany PHBT programs are not yet widely established. Paradoxically, this situation, paired with the extensive German Trauma Registry, provides aprime opportunity for comprehensive prospective cohort studies, addressing the balance between PHBT benefits, logistical feasibility, and implementation strategies. Such studies are essential for establishing guidelines and integrating PHBT efficiently into German trauma care protocols.

Abstract B048: Qualitative analysis of fieldnote and interview data for planning a food bank- based breast cancer screening intervention

Abstract Among individuals and communities with low-income, the experience of food insecurity is associated with greater delays in recommended mammography screening and late-stage breast cancer at diagnosis. Community-based interventions that address barriers to breast cancer screening in diverse communities of women with food insecurity can increase screening uptake, ultimately improving cancer health equity. In partnership with Sacramento Food Bank and Family Services (SFBFS), the largest non-profit provider of social services in Sacramento County, this study identified barriers and facilitators to implementing a breast cancer screening intervention in a food distribution setting, assessing the preliminary acceptability and logistical feasibility of the proposed intervention. Qualitative data about food bank distribution events and the clients served was collected over 24 weeks using participant observation with semi-structured fieldnotes and interviews, then analyzed via directed content analysis guided by the well-defined domains and determinants in the Consolidated Framework for Implementation Research (CFIR) and coded using Dedoose software. Fieldnotes were completed for 12 community food distribution events, and 20 stakeholder interviews were conducted with purposefully sampled food bank staff (N=10) and female clients (N=10) who regularly attend events. The results of this qualitative analysis identified barriers and facilitators to implementation in all CFIR domains, describing current workflows for food distribution events and existing health education efforts, capacity, client engagement logistics and modes of delivery, and resources available or needed to support implementation. Prominent CFIR determinants included characteristics of individuals, specifically the innovation recipients’ capability and motivation to receive a breast cancer screening intervention in this context. Participants often pointed out their awareness of important preventative behaviors such as nutrition while also acknowledging barriers such as time constraints, accessibility of breast cancer screening services, and culturally-specific health beliefs and practices. Determinants in the outer setting, inner setting, innovation characteristics, and process that relate to the overall theme of sustainability were identified as potential barriers including financing, the availability of resources, internal and external pressure to change, and the process of engaging with clients while they are at the food distribution event. Facilitators included buy-in from SFBFS leadership and staff, and the benefit of collaborating with reputable local partners. Intervention format should include tailored messaging that is culturally appropriate and empowers individuals to obtain recommended screening. Content of the intervention should provide interactive assistance that facilitates local support for screening eligibility and services. Overall, there was consensus that promoting breast cancer screening in the food distribution setting was beneficial and welcomed by all stakeholders. Citation Format: Charlotte L.

Personalized dose selection for the first Waldenström macroglobulinemia patient on the PRECISE CURATE.AI trial

The digital revolution in healthcare, amplified by the COVID-19 pandemic and artificial intelligence (AI) advances, has led to a surge in the development of digital technologies. However, integrating digital health solutions, especially AI-based ones, in rare diseases like Waldenström macroglobulinemia (WM) remains challenging due to limited data, among other factors. CURATE.AI, a clinical decision support system, offers an alternative to big data approaches by calibrating individual treatment profiles based on that individual’s data alone. We present a case study from the PRECISE CURATE.AI trial with a WM patient, where, over two years, CURATE.AI provided dynamic Ibrutinib dose recommendations to clinicians (users) aimed at achieving optimal IgM levels. An 80-year-old male with newly diagnosed WM requiring treatment due to anemia was recruited to the trial for CURATE.AI-based dosing of the Bruton tyrosine kinase inhibitor Ibrutinib. The primary and secondary outcome measures were focused on scientific and logistical feasibility. Preliminary results underscore the platform’s potential in enhancing user and patient engagement, in addition to clinical efficacy. Based on a two-year-long patient enrollment into the CURATE.AI-augmented treatment, this study showcases how AI-enabled tools can support the management of rare diseases, emphasizing the integration of AI to enhance personalized therapy.

A safety and feasibility analysis on the use of cold-stored platelets in combat trauma.

Damage-control resuscitation has come full circle, with the use of whole blood and balanced components. Lack of platelet availability may limit effective damage-control resuscitation. Platelets are typically stored and transfused at room temperature and have a short shelf-life, while cold-stored platelets (CSPs) have the advantage of a longer shelf-life. The US military introduced CSPs into the battlefield surgical environment in 2016. This study is a safety analysis for the use of CSPs in battlefield trauma. The Department of Defense Trauma Registry and Armed Services Blood Program databases were queried to identify casualties who received room-temperature-stored platelets (RSPs) or both RSPs and CSPs between January 1, 2016, and February 29, 2020. Characteristics of recipients of RSPs and RSPs-CSPs were compared and analyzed. A total of 274 patients were identified; 131 (47.8%) received RSPs and 143 (52.2%) received RSPs-CSPs. The casualties were mostly male (97.1%), similar in age (31.7 years), with a median Injury Severity Score of 22. There was no difference in survival for recipients of RSPs (88.5%) versus RSPs-CSPs (86.7%; p = 0.645). Adverse events were similar between the two cohorts. Blood products received were higher in the RSPs-CSPs cohort compared with the RSPs cohort. The RSPs-CSPs cohort had more massive transfusion (53.5% vs. 33.5%, p = 0.001). A logistic regression model demonstrated that use of RSPs-CSPs was not associated with mortality, with an adjusted odds ratio of 0.96 (p > 0.9; 95% confidence interval, 0.41-2.25). In this safety analysis of RSPs-CSPs compared with RSPs in a combat setting, survival was similar between the two groups. Given the safety and logistical feasibility, the results support continued use of CSPs in military environments and further research into how to optimize resuscitation strategies.

Methods for the estimation of direct and indirect vaccination effects by combining data from individual- and cluster-randomized trials.

Both individually and cluster randomized study designs have been used for vaccine trials to assess the effects of vaccine on reducing the risk of disease or infection. The choice between individually and cluster randomized designs is often driven by the target estimand of interest (eg, direct versus total), statistical power, and, importantly, logistic feasibility. To combat emerging infectious disease threats, especially when the number of events from one single trial may not be adequate to obtain vaccine effect estimates with a desired level of precision, it may be necessary to combine information across multiple trials. In this article, we propose a model formulation to estimate the direct, indirect, total, and overall vaccine effects combining data from trials with two types of study designs: individual-randomization and cluster-randomization, based on a Cox proportional hazards model, where the hazard of infection depends on both vaccine status of the individual as well as the vaccine status of the other individuals in the same cluster. We illustrate the use of the proposed model and assess the potential efficiency gain from combining data from multiple trials, compared to using data from each individual trial alone, through two simulation studies, one of which is designed based on a cholera vaccine trial previously carried out in Matlab, Bangladesh.

Deploying whole blood to the battlefield-The Israel Defense Forces Medical Corps initial experience during the 2023 war.

Military and prehospital medical organizations invest significant resources to advance the treatment of trauma patients aiming to reduce preventable deaths. Focus is on hemorrhage control and volume resuscitation with blood products, with adoption of Remote Damage Control Resuscitation (RDCR) guidelines. The Israel Defense Forces Medical Corps (IDF-MC) has been using tranexamic acid and freeze-dried plasma (FDP) as part of its RDCR protocol for more than a decade. In recent years, low-titer group O whole blood (LTOWB) has been integrated, on IDF evacuation helicopters and expanded to mobile ambulances, complementing FDP use in treating trauma patients in state of profound shock. During the war that erupted in October 2023, the IDF-MC made a decision to bring LTOWB forward, and to equip every combat brigade level mobile intensive care units with LTOWB, onboard armored vehicles. The goal was to make whole blood available as close as possible to the point of injury and within minutes from time of injury. We describe the IDF-MCs' efforts to bring LTOWB to the front lines and present four cases in which LTOWB was administered. All patients were young male, with significant blood loss following penetrating injuries. One patient died in the operating room, following hospital arrival and emergency thoracotomy. The others survived. Our initial experience with bringing LTOWB as close as possible to the point of injury during high intensity fighting is encouraging, showing patient benefit along with logistic feasibility. After action reports and data collection will continue.

Medical Students' Perception of Telesimulation Training: A Qualitative Analysis.

Over the past 2 decades, simulation-based learning has become an essential part of medical training. Simulated clinics have proven to be effective for training medical students. Even so, this learning method presents organizational and financial challenges that limit its dissemination to all medical students, especially since the COVID-19 pandemic. Simulated teleconsultation retains the advantages of interactive simulated clinics while offering concrete solutions to the challenges faced. The project aims to explore students' perspectives on simulated teleconsultation training compared to simulated clinics in person. Ten pre-clerkship students in the Faculty of Medicine at the University of Ottawa participated in interviews following in-person and teleconsultation simulated clinic sessions. The interview guide was developed based on previous work. The questions asked concerned experience with teleconsultation, interaction with the tutor and patient, practical or logistical obstacles, educational value and feasibility. The authors evaluated the results using a thematic analysis. The interview analysis showed that the tutor feedback received during the simulated teleconsultation was comparable to that received after the in-person simulated clinic. Although most of the students enjoy teleconsultation, they raised the challenge of carrying out physical examinations and creating a personal connection with the tutor/patient. Given the circumstances of the pandemic and students' comfort with technology, the new generation of medical students seems prepared to embrace teleconsultation. The themes identified in the analysis will enable the necessary adjustments to be made in order to optimize their teleconsultation training, an inextricable step in promoting the active offer of healthcare services.

Utilizing interprofessional education to foster diversity, equity, and inclusion concepts related to gender affirming care

Interprofessional education (IPE) is on the rise in healthcare fields for several reasons. IPE teaches the collaborative skills necessary for healthcare students to succeed in an increasingly diverse workforce. IPE also creates space for healthcare organizations to develop diversity, equity, and inclusion (DEI) objectives within curriculum and clinical practice. IPE's focus on diversity is important because recent research indicates a lag in DEI initiatives in healthcare. To better integrate DEI objectives into healthcare curricula, faculty from an OTD and MAT program developed an interprofessional assignment that could be implemented across multiple programs. The assignment was designed to improve DEI and IPE competence in OT and AT education.An OTD and a MAT course were chosen to pilot the IPE assignment. These courses were selected for two reasons: curricular content and logistic feasibility. A virtual synchronous and asynchronous format was determined as the best structure for the assignment. Students were asked to complete assigned readings and review a video about culturally sensitive topics, meet as an interprofessional group to discuss a healthcare encounter between a clinical staff and a transgender individual, and participate in an intraprofessional discussion board activity.The primary student learning outcomes for this assignment were threefold 1) Demonstrate use of interprofessional collaborative skills such as communication and roles responsibilities 2) Analyze how interprofessional collaborative skills might be utilized to care for diverse populations and 3) Integrate the use of DEI constructs within discussions of planned care. A rubric was used to assess students in each of these areas. Additionally, a thematic analysis was generated to understand how students’ use of interprofessional education skills and knowledge could enhance the care of diverse populations.Both groups of students in the pilot scored well. The average overall grade for occupational students was 37.25/40 (93 %) and the average overall grade for the athletic training students was 36/40 (90 %). The assignment analysis identified three improvements in student understanding, specifically enhanced quality of care, decreased knowledge gaps, and greater ability to check biases and accountability.

Automatic model generation for material flow simulations of Third-Party Logistics

AbstractThe use of Third-Party Logistics (TPL) is a common practice among manufacturing companies seeking to increase profitability. However, the tender process in selecting a TPL service provider can be challenging, requiring significant effort from both the tendering company and the service provider. The latter must meticulously plan processes and calculate pricing positions while running the risk of losing the bid. This risk impedes verifying logistical feasibility and comparing different logistic concepts extensively, such as layouts, which are often work-intensive. With the ongoing progress of research toward automatic simulation model generation for material flow, it is left to answer whether such approaches can improve the planning processes of TPL service providers by using planning data to generate simulation models. Therefore, this work presents a system with an underlying ontology to generate material flow simulations by developing a model transformation methodology. The system’s functions are tested to determine whether they can support the planning process using defined case studies that cover everyday planning decisions. As a result, the system is capable of verifying the performance of planned logistic systems with minimal manual modelling efforts. This encompasses the evaluation of alternative logistical concepts for configuring the planned systems.

Development of a behaviour change intervention to promote sanitation and latrine use in rural India

BackgroundAcross developing countries poor sanitation is associated with disease often found widespread in rural populations.ObjectivesThis objective of this study was to conduct a formative research and feasibility evaluation of the behavioural intervention designed to improve latrine use in rural India.MethodsStudy conducted in four villages of Rajasthan, where latrine use is low and open defecation may spread disease. To identify the intervention a literature review was conducted, a survey of 497 households, and focus groups in village households (8–10 women and children). Seven focus groups with 63 women were conducted. Based on the survey results, the behaviour change intervention is developed utilising the Capability-Opportunity-Motivation-behaviour model and MINDSPACE framework. One intervention component involves psychological aspects that engage villagers through a pledge; the other component is provision of small incentives to facilitate latrine use. Feasibility and acceptability of the intervention was examined in the study population. The 30-day intervention was delivered to women in 38 randomly selected households who despite having a functional latrine did not use it. Thematic analysis, binary logistic regression analysis and feasibility evaluation of the intervention conducted. Post-intervention feedback from 22 participating households was obtained.ResultsThe piloted intervention was feasible and so a revised design is offered. Results driving this evaluation include barriers identified, and used to improved intervention design in the current study. Village authority figures influenced behaviours across the villages and so did factors of convenience (β = 5.28, p < 0.01), relief (β = 5.49, p < 0.01), comfort (β = 2.36, p < 0.01), Construction cost (β=-1.98, p < 0.01) and safety (β = 2.93, p < 0.01) were significant concerns associated with latrine use in the context of prevalent OD in the region. The logistic regression baseline model for the dependant variables indicated a significant increase in latrine use. Based on the feasibility study, the intervention is refined in several ways.ConclusionsOur theory-driven approach improves latrine use in Rajasthan and offers a useful tool to facilitate hygiene behaviour.

CURATE.AI-assisted dose titration for anti-hypertensive personalized therapy: study protocol for a multi-arm, randomized, pilot feasibility trial using CURATE.AI (CURATE.AI ADAPT trial).

Artificial intelligence-driven small data platforms such as CURATE.AI hold potential for personalized hypertension care by assisting physicians in identifying personalized anti-hypertensive doses for titration. This trial aims to assess the feasibility of a larger randomized controlled trial (RCT), evaluating the efficacy of CURATE.AI-assisted dose titration intervention. We will also collect preliminary efficacy and safety data and explore stakeholder feedback in the early design process. In this open-label, randomized, pilot feasibility trial, we aim to recruit 45 participants with primary hypertension. Participants will be randomized in 1:1:1 ratio into control (no intervention), home blood pressure monitoring (active control; HBPM), or CURATE.AI arms (intervention; HBPM and CURATE.AI-assisted dose titration). The home treatments include 1 month of two-drug anti-hypertensive regimens. Primary endpoints assess the logistical (e.g. dose adherence) and scientific (e.g. percentage of participants for which CURATE.AI profiles can be generated) feasibility, and define the progression criteria for the RCT in a 'traffic light system'. Secondary endpoints assess preliminary efficacy [e.g. mean change in office blood pressures (BPs)] and safety (e.g. hospitalization events) associated with each treatment protocol. Participants with both baseline and post-treatment BP measurements will form the intent-to-treat analysis. Following their involvement with the CURATE.AI intervention, feedback from CURATE.AI participants and healthcare providers will be collected via exit survey and interviews. Findings from this study will inform about potential refinements of the current treatment protocols before proceeding with a larger RCT, or potential expansion to collect additional information. Positive results may suggest the potential efficacy of CURATE.AI to improve BP control. NCT05376683.

A Mobile App for Postoperative Pain Management Among Older Veterans Undergoing Total Knee Arthroplasty: Mixed Methods Feasibility and Acceptability Pilot Study.

Prescription opioid misuse risk is disproportionate among veterans; military veterans wounded in combat misuse prescription opioids at an even higher rate (46.2%). Opioid misuse is costly in terms of morbidity, mortality, and humanitarian and economic burden and costs the Civilian Health and Medical Program of the Department of Veterans Affairs more than US $1.13 billion annually. Preventing opioid misuse at the time of prescription is a critical component in the response to the opioid crisis. The CPMRx mobile app has been shown to decrease the odds of opioid misuse during the postoperative period. The overarching purpose of this feasibility pilot study was to explore whether deploying a mobile app (CPMRx) to track postoperative pain and medication use is feasible in a Department of Veterans Affairs medical center. In support of this goal, we had four complementary specific aims: (1) determine the technological and logistical feasibility of the mobile app, (2) assess the acceptability of the mobile app to participants, (3) measure demand for and engagement with the mobile app, and (4) explore the potential use of the mobile app to patients and providers. Participants (N=10) were veterans undergoing total knee arthroplasty within the Veterans Health Administration provided with the CPMRx app to self-manage their pain during their 7-day at-home recovery following surgery. CPMRx uses scientifically validated tools to help clinicians understand how a patient can use the least amount of medication while getting the most benefit. The suite of software includes a mobile app for patients that includes a behavioral health intervention and a clinical decision support tool for health care providers that provides feedback about pain and medication use trends. Patients filled out paper questionnaires regarding acceptability at their postoperative follow-up appointment. Overall, quantitative measures of acceptability were high. The average rating for the amount of time required to use the app was 4.9 of 5 (5="very little"), and the average rating for ease of use was 4.4 of 5 (5="very easy"). Open-ended questions also revealed that most participants found ease of use to be high. Demand and engagement were high as well with a mean number of mobile app entries of 34.1 (SD 20.1) during the postoperative period. There were no reported technological or logistical issues with the mobile app. Participants took an average of 25.13 (SD 14.37) opioid tablets to manage their postoperative pain. Results of this study revealed that the use of a mobile app for pain and medication management during postoperative recovery was both feasible and acceptable in older veterans undergoing total knee arthroplasty within the Veterans Health Administration. The wide variation in opioid consumption across participants revealed the potential use of the mobile app to provide actionable insights to clinicians if adopted more widely.

MD Anderson Phase III Randomized Preoperative Stereotactic Radiosurgery (SRS) vs. Postoperative SRS for Brain Metastases Trial

Postoperative stereotactic radiation therapy/radiosurgery (SRT/SRS) is being evaluated in comparison to Preoperative SRT for brain metastases (mets) in a limited number of prospective clinical trials. Our objective is to address the significant knowledge gap concerning the logistics of preoperative SRT in comparison to postoperative SRT in a randomized controlled study. Patients with brain mets with at least 1 surgically operable met were randomized (1:1) to Preop vs Postop SRT. In this abstract, we present non-primary endpoint data on the trial concept and logistics of treatment for this data safety monitoring board reviewed study. Patients enrolled had 1-2 lesions resected and <15 lesions treated at time of SRT to best reflect the standard population that receive SRT and surgery at our institution. From 12/2018 to 12/2022, 99 patients with 1-2 operable brain mets were enrolled and randomized to Preop (n = 49) or Postop (n = 50) SRT. Males represented 56% of the cohort compared to females, and <25% were age 18-49 years, while 27%, 29, and 19% respectively were 50-59, 60-69, and > = 70. The most frequent histologies enrolled were lung (29%), renal cell (15%), melanoma (14%), and breast (11%) cancers. The majority of patients (83%) had 1-4 brain mets on their baseline MRI and 91% subsequently had a single lesion resected. Seventy-nine patients completed both SRT and surgery, while 9% received no therapy due to drop out before study therapy initiation. Among patients receiving both therapies in the combined cohort, 68% received a non-invasive stereotactic radiosurgery instrument to the randomized cavity lesion compared to 32% receiving LINAC based SRT. Treatment of the lesion or cavity with single fraction SRT was 51% in the Preop arm vs 31% in the Postop arm. Multi-fraction (3-5 SRT) was 67% in the Postop cohort in contrast to 47% in the Preop cohort. Time from randomization to RT was 5.6 days and 33.7 days in the Preop and Postop cohorts respectively, and for surgery was 10.2 days vs 12.9 days in the Postop vs Preop cohorts. The average time from RT to surgery was 7.3 days in the Preop arm and 23.5 days in the Postop arm (to allow for incisional healing time). In one of the early initiated randomized prospective cohorts of Preop vs Postop SRT, we demonstrated logistical feasibility with an efficient clinical trial workflow for study treatment. Differences in Preop vs Postop logistics reflect clinical practice differences in time-to-treatment. Therapy with various modalities reflected real-world practice and possibly provider preferences in technique when addressing the nature of delineating cavities and changes in cavity volume with regard to fractionation. Independent of the primary outcomes, our data provides insights in the practical management of patients receiving these two modalities of therapy, and further data at the completion of trial will address relevant primary outcomes.

Underground capsule pipeline logistic system Feasibility study of an urban application

A feasibility study of an underground capsule-pipe system for storing and transporting small items and waste is presented. “Hyperloop for packages” for the last/first/mile/yard all the way to and from the final user in apartments and establishments. In many cases, one capsule of 2 kg can do the same job as a car with 1000 times larger mass. The conclusion is that such a system is technically feasible and economically good for all stakeholders. In one scenario, 30% less traffic and CO2 and freed space was valued more than system cost. Still, society is not yet prepared and unaware of the possibility. The storybook Pipeville 2030 and a scale model of capsule-pipe logistics in LEGO were created to visualize and play around with during workshops, surveys, and story writing. Results from the first survey and Lisa's user story are presented. Finally, areas for future research are suggested.

Market-driven assessment of alternate aquafeed ingredients: seafood waste transformation as a case study

With the increase in worldwide demand for seafood, the current plateau in production from wild-harvest fisheries has resulted in the rapid growth of the aquaculture sector. Aquaculture relies on quality ingredients such as fishmeal, but cost concerns have led to the investigation of a variety of alternate plant and animal by-products and microbial sources as aquafeed ingredients. Evaluation of alternative aquafeed has traditionally focused on their effects on the growth and immune status of the fish and not always on market-driven assessments of the final edible product. One of the commonly researched groups of alternative ingredients is seafood waste, which, after transformation, has potentially beneficial nutritional characteristics. Transformation, which includes rendering, enzyme hydrolysis and use as a feed source for insects and microbial species, is intended to provide stability and enhance the logistical feasibility of the waste as an aquafeed ingredient. This review discusses transformed fish waste in aquafeeds and describes some of the market and end-user implications (composition, edible safety and quality, sustainability metrics and consumer perceptions) of this approach.

Cloud-based platform to enable autonomous container handling

Autonomous cargo handling can increase usage of the short sea in last-mile shipping which can reduce emissions and road traffic congestion. For commercial and logistical feasibility of autonomous operations, a connected digital solution is required where all stakeholders participate throughout the cargo lifecycle. The connected digital solution solves the challenges around cargo data flow and information sharing. A cloud-based experimental platform is designed and developed that provides cargo information management and sharing for autonomous container handling. The platform essentially enables autonomous operations and improves the efficiency of cargo flow from the origin to the destination, while keeping all stakeholders, actors, and systems in the loop.

The Pediatric Guideline Adherence and Outcomes (PEGASUS Argentina) program in severe traumatic brain injury: study protocol adaptations during the COVID-19 pandemic for a multisite implementation-effectiveness cluster randomized controlled trial

BackgroundThe aim of this protocol is to describe the study protocol changes made and subsequently implemented to the Pediatric Guideline Adherence and Outcomes (PEGASUS) Argentina randomized controlled trial (RCT) for care of children with severe traumatic brain injuries (TBI) imposed by the COVID-19 pandemic. The PEGASUS study group met in spring 2020 to evaluate available literature review guidance and the study design change or pausing options due to the potential interruption of research.MethodsAs a parallel cluster RCT, pediatric patients with severe TBIs are admitted to 8 control (usual care) and 8 intervention (PEGASUS program) hospitals in Argentina, Chile, and Paraguay. PEGASUS is an intervention that aims to increase guideline adherence and best practice care for improving patient outcomes using multi-level implementation science-based approaches. Strengths and weaknesses of proposed options were assessed and resulted in a decision to revert from a stepped wedge to a parallel cluster RCT but to not delay planned implementation.Discussion The parallel cluster design was considered more robust and flexible to secular interruptions and acceptable and feasible to the local study sites in this situation. Due to the early stage of the study, the team had flexibility to redesign and implement a design more compatible with the conditions of the research landscape in 2020 while balancing analytical methods and power, logistical and implementation feasibility, and acceptability. As of fall 2022, the PEGASUS RCT has been active for nearly 2 years of implementation and data collection, scheduled to be completed in in fall 2023. The experience of navigating research during this period will influence decisions about future research design, strategies, and contingencies.Trial registrationPediatric Guideline Adherence and Outcomes-Argentina.

Are We Paying More to Consume Substandard Drinking Water? Crowd-Sourced Water Education Study in a South-Asian Megacity

South. Environment and health-related data are inadequate and strongly rely on governmental-mediated observation. The present work is the first of its kind attempt to gather relevant information on potable water quality using mass citizen engagement over a south Asian megacity, Kolkata. The city has a long history associated with water-borne diseases and presently numerous reports on sickness from drinking water contamination have been published in the local newspapers. The current work crowdsourced water sampling throughout the city and analyzed information regarding biological contaminants for five existing water types. 300 citizens were mobilized and trained in water collection through audio-visual communication workshops and together 570 samples of water have been collected from different parts of the city. Water sample collecting points were created over the city and samples were taken to the analysis hub where it was analyzed for standard coliform test and for total dissolved solid (TDS) and pH. The results show that the most expensive water types (20l commercialized packaged drinking water bottles) are the worst in terms of water quality. Governmental-free drinking water was found to be much safer as compared to packaged drinking water. 44% of the packaged drinking water was found to be contaminated with coliform bacteria and we did a comparative analysis with reports from different developing countries and found that such high occurrence was not reported in any cities across the world. We communicated the results to the participants and further, conducted semi-structured interviews to understand the perception of water quality and the driving force behind the choice of a particular water type. It was also found that logistical feasibility is the primary reason behind selecting the 20l bottle. The blind faith in commercially packaged drinking water has been reflected in the interview. The present studies confirm the potential of crowdsourcing of environmental-health data in the global south and successfully accomplish potable water analysis through crowdsource sampling over a south Asian megacity. Such robust methods could be easily scaled up and follow-up discussions can definitely improve water literacy among the participants in Global South.
