Objective: To assess the availability and source of guidelines for common infections in European paediatric hospitals and determine their content and characteristics.Design: Participating hospitals completed an online questionnaire on the availability and characteristics of antibiotic prescribing guidelines and on empirical antibiotic treatment including duration of therapy for 5 common infection syndromes: respiratory tract, urinary tract, skin and soft tissue, osteoarticular and sepsis in neonates and children.Results: 84 hospitals from 19 European countries participated in the survey of which 74 confirmed the existence of guidelines. Complete guidelines (existing guidelines for all requested infection syndromes) were reported by 20% of hospitals and the majority (71%) used a range of different sources. Guidelines most commonly available were those for urinary tract infection (UTI) (74%), neonatal sepsis (71%) and sepsis in children (65%). Penicillin and amoxicillin were the antibiotics most commonly recommended for respiratory tract infections (RTIs) (up to 76%), cephalosporin for UTI (up to 50%) and for skin and soft tissue infection (SSTI) and bone infection (20% and 30%, respectively). Antistaphylococcal penicillins were recommended for SSTIs and bone infections in 43% and 36%, respectively. Recommendations for neonatal sepsis included 20 different antibiotic combinations. Duration of therapy guidelines was mostly available for RTI and UTI (82%). A third of hospitals with guidelines for sepsis provided recommendations for length of therapy.Conclusions: Comprehensive antibiotic guideline recommendations are generally lacking from European paediatric hospitals. We documented multiple antibiotics and combinations for most infections. Considerable improvement in the quality of guidelines and their evidence base is required, linking empirical therapy to resistance rates. [ABSTRACT FROM AUTHOR]

Background: The VACCELERATE Pan-European Scientific network aims to strengthen the foundation of vaccine trial research across Europe by following the principles of equity, inclusion, and diversity. The VACCELERATE Volunteer Registry network provides access to vaccine trial sites across the European region and supports a sustainable volunteer platform for identifying potential participants for forthcoming vaccine clinical research., Objective: The aim of this study was to approach members of patient advocacy groups (PAGs) across Europe to assess their willingness to register for the VACCELERATE Volunteer Registry and their perspectives related to participating in vaccine trials., Methods: In an effort to understand how to increase recruitment for the VACCELERATE Volunteer Registry, a standardized survey was developed in English and translated into 8 different languages (Dutch, English, French, German, Greek, Italian, Spanish, and Swedish) by the respective National Coordinator team. The online, anonymous survey was circulated, from March 2022 to May 2022, to PAGs across 10 European countries (Belgium, Cyprus, Denmark, France, Germany, Greece, Ireland, Italy, Spain, and Sweden) to share with their members. The questionnaire constituted of multiple choice and open-ended questions evaluating information regarding participants' perceptions on participating in vaccine trials and their willingness to become involved in the VACCELERATE Volunteer Registry., Results: In total, 520 responses were collected and analyzed. The PAG members reported that the principal criteria influencing their decision to participate in clinical trials overall are (1) the risks involved, (2) the benefits that will be gained from their potential participation, and (3) the quality and quantity of information provided regarding the trial. The survey revealed that, out of the 520 respondents, 133 individuals across all age groups were "positive" toward registering in the VACCELERATE Volunteer Registry, with an additional 47 individuals reporting being "very positive." Respondents from Northern European countries were 1.725 (95% CI 1.206-2.468) times more likely to be willing to participate in the VACCELERATE Volunteer Registry than respondents from Southern European countries., Conclusions: Factors discouraging participants from joining vaccine trial registries or clinical trials primarily include concerns of the safety of novel vaccines and a lack of trust in those involved in vaccine development. These outcomes aid in identifying issues and setbacks in present registries, providing the VACCELERATE network with feedback on how to potentially increase participation and enrollment in trials across Europe. Development of European health communication strategies among diverse public communities, especially via PAGs, is the key for increasing patients' willingness to participate in clinical studies., (©Sophia Themistocleous, Christos D Argyropoulos, Paris Vogazianos, George Shiamakkides, Evgenia Noula, Andria Nearchou, Andreas Yiallouris, Charalampos Filippou, Fiona A Stewart, Markela Koniordou, Ioannis Kopsidas, Helena H Askling, Sirkka Vene, Amandine Gagneux-Brunon, Jana Baranda Prellezo, Elena Álvarez-Barco, Jon Salmanton-García, Janina Leckler, Alan J Macken, Ruth Joanna Davis, Anna Maria Azzini, Charis Armeftis, Margot Hellemans, Romina Di Marzo, Catarina Luis, Ole F Olesen, Olena Valdenmaiier, Stine Finne Jakobsen, Pontus Nauclér, Odile Launay, Patrick Mallon, Jordi Ochando, Pierre van Damme, Evelina Tacconelli, Theoklis Zaoutis, Oliver A Cornely, Zoi Dorothea Pana.

Background: The pan-European VACCELERATE network aims to implement the first transnational harmonized and sustainable vaccine trial Volunteer Registry, being a single entry point for potential volunteers of large-scale vaccine trials across Europe. This work exhibits a set of harmonized vaccine trial-related educational and promotional tools for the general public, designed and disseminated by the pan-European VACCELERATE network., Objective: This study primarily aimed to design and develop a standard toolkit to increase positive attitudes and access to trustworthy information for better access and increased recruitment to vaccine trials for the public. More specifically, the produced tools are focused on inclusiveness and equity, and are targeting different population groups, including underserved ones, as potential volunteers for the VACCELERATE Volunteer Registry (older individuals, migrants, children, and adolescents). The promotional and educational material is aligned with the main objectives of the Volunteer Registry to increase public literacy and awareness regarding vaccine-related clinical research or trials and trial participation, including informed consent and legal issues, side effects, and frequently asked questions regarding vaccine trial design., Methods: Tools were developed per the aims and principles of the VACCELERATE project, focusing on trial inclusiveness and equity, and are adjusted to local country-wise requirements to improve public health communication. The produced tools are selected based on the cognitive theory, inclusiveness, and equity of differently aged and underrepresented groups, and standardized material from several official trustworthy sources (eg, COVID-19 Vaccines Global Access; the European Centre for Disease Prevention and Control; the European Patients' Academy on Therapeutic Innovation; Gavi, the Vaccine Alliance; and the World Health Organization). A team of multidisciplinary specialists (infectious diseases, vaccine research, medicine, and education) edited and reviewed the subtitles and scripts of the educational videos, extended brochures, interactive cards, and puzzles. Graphic designers selected the color palette, audio settings, and dubbing for the video story-tales and implemented QR codes., Results: This study presents the first set of harmonized promotional and educational materials and tools (ie, educational cards, educational and promotional videos, extended brochures, flyers, posters, and puzzles) for vaccine clinical research (eg, COVID-19 vaccines). These tools inform the public about possible benefits and disadvantages of trial participation and build confidence among participants about the safety and efficacy of COVID-19 vaccines and the health care system. This material has been translated into several languages and is intended to be freely and easily accessible to facilitate dissemination among VACCELERATE network participant countries and the European and global scientific, industrial, and public community., Conclusions: The produced material could help fill knowledge gaps of health care personnel, providing the appropriate future patient education for vaccine trials, and tackling vaccine hesitancy and parents' concerns for potential participation of children in vaccine trials., (©Christos D Argyropoulos, Janina Leckler, Jon Salmanton-García, Marinos Constantinou, Alexandra Alexandrou, Sophia Themistocleous, Evgenia Noula, George Shiamakkides, Andria Nearchou, Fiona A Stewart, Kerstin Albus, Markela Koniordou, Ioannis Kopsidas, Orly Spivak, Margot Hellemans, Greet Hendrickx, Ruth Joanna Davis, Anna Maria Azzini, Paula Valle Simon, Antonio Javier Carcas-Sansuan, Helena Hervius Askling, Sirkka Vene, Jana Baranda Prellezo, Elena Álvarez-Barco, Alan J Macken, Romina Di Marzo, Catarina Luís, Ole F Olesen, Jesus A Frias Iniesta, Imre Barta, Krisztina Tóth, Murat Akova, Marc M J Bonten, Miriam Cohen-Kandli, Rebecca Jane Cox, Lenka Součková, Petr Husa, Ligita Jancoriene, Odile Launay, Jens Lundgren, Patrick Mallon, Charis Armeftis, Laura Marques, Pontus Naucler, Jordi Ochando, Evelina Tacconelli, Pierre van Damme, Theoklis Zaoutis, Sanne Hofstraat, Patricia Bruijning-Verhagen, Markus Zeitlinger, Oliver A Cornely, Zoi Dorothea Pana.

Background: Misuse, overuse of antimicrobials and increasing rates of antimicrobial resistance are well-recognized problems throughout Europe. The aim of this survey was to describe the current pediatric antibiotic stewardship (PAS) landscape across Europe and identify gaps, in terms of national programs, networks and guidelines., Methods: A survey of 17 questions was circulated in July 2019 among 24 European pediatric infectious disease researchers and clinicians, professors and heads of department on the existence of PAS programs, national networks and meetings, established competencies, metrics and guidelines., Results: We received responses from 23 countries. National guidelines on the management of children with common infections treated in hospital settings exist in 15 of 23 (70%); only 8 of 15 (53%) had been updated within the previous 4 years. Most provide guidance on antibiotic initiation and duration (14 of 15, 93%), but few on when to transition from intravenous to oral antibiotics (7 of 15, 47%). National PAS competencies have only been developed in 4 countries; only 1 addressed both community and hospital prescribing. Organized national PAS networks are only established in the United Kingdom and Germany; 21 of 23, 91% countries had no agreed metric for antibiotic prescribing in children; 2 of 23 were based on daily defined doses., Conclusions: Fragmented implementation of PAS programs, no agreed metrics, lack of established PAS competencies and national PAS networks along with inexistent funding is alarming in view of existing high rates of antimicrobial resistance in Europe.

Background: Antibiotics are the most common medicines prescribed to children in hospitals and the community, with a high proportion of potentially inappropriate use. Antibiotic misuse increases the risk of toxicity, raises healthcare costs, and selection of resistance. The primary aim of this systematic review is to summarize the current state of evidence of the implementation and outcomes of pediatric antimicrobial stewardship programs (ASPs) globally., Methods: MEDLINE, Embase and Cochrane Library databases were systematically searched to identify studies reporting on ASP in children aged 0-18 years and conducted in outpatient or in-hospital settings. Three investigators independently reviewed identified articles for inclusion and extracted relevant data., Results: Of the 41,916 studies screened, 113 were eligible for inclusion in this study. Most of the studies originated in the USA (52.2%), while a minority were conducted in Europe (24.7%) or Asia (17.7%). Seventy-four (65.5%) studies used a before-and-after design, and sixteen (14.1%) were randomized trials. The majority (81.4%) described in-hospital ASPs with half of interventions in mixed pediatric wards and ten (8.8%) in emergency departments. Only sixteen (14.1%) studies focused on the costs of ASPs. Almost all the studies (79.6%) showed a significant reduction in inappropriate prescriptions. Compliance after ASP implementation increased. Sixteen of the included studies quantified cost savings related to the intervention with most of the decreases due to lower rates of drug administration. Seven studies showed an increased susceptibility of the bacteria analysed with a decrease in extended spectrum beta-lactamase producers E. coli and K. pneumoniae; a reduction in the rate of P. aeruginosa carbapenem resistance subsequent to an observed reduction in the rate of antimicrobial days of therapy; and, in two studies set in outpatient setting, an increase in erythromycin-sensitive S. pyogenes following a reduction in the use of macrolides., Conclusions: Pediatric ASPs have a significant impact on the reduction of targeted and empiric antibiotic use, healthcare costs, and antimicrobial resistance in both inpatient and outpatient settings. Pediatric ASPs are now widely implemented in the USA, but considerable further adaptation is required to facilitate their uptake in Europe, Asia, Latin America and Africa., Competing Interests: Competing interestsThe authors declare that they have no competing interests., (© The Author(s). 2019.)
