Introduction Copyright: © 2023 by the authors. Licensee MDPI, Basel, Switzerland. The emergence of antimicrobial resistance represents a serious problem for public This article is an open access article health systems all over the world. In fact, in 2019, the WHO listed antimicrobial resistance distributed under the terms and among the ten main threats facing global health [1]. Inappropriate use is one of the main conditions of the Creative Commons causes of antimicrobial resistance [2,3]. One of the strategies to combat the problem has Attribution (CC BY) license (https:// been the establishment of programs to optimize antimicrobial stewardship [4,5]. In Spain, creativecommons.org/licenses/by/ programs of this kind were initiated in the consensus document by Rodríguez-Baño et al. 4.0/). published in 2012, which outlined the conditions required for their implementation and Antibiotics 2023, 12, 250. https://doi.org/10.3390/antibiotics12020250 https://www.mdpi.com/journal/antibiotics Antibiotics 2023, 12, 250 2 of 10 made recommendations for their further development [6]. More recently, in 2022, the Spanish Society of Paediatric Infectious Diseases published their position statement about the implementation of paediatric antimicrobial stewardship programs, providing tools to facilitate their application in hospitals throughout the regional health care systems in Spain [7]. In this country, these programs are known as PROA, an acronym of the title in Spanish, PRogramas de Optimización de Antimicrobianos. In pediatric populations, infectious diseases are among the main causes of hospital- ization and consultation, and antibiotics are the main therapeutic option in primary and hospital care [2,8]. The specific features of infectious diseases in pediatric patients, and the differences in the efficacy and safety of antimicrobials in this population with respect to adults, have contributed to the significant increase in PROA designed for children in recent years [2,9–15]. Since its creation in 2006, the Catalan Health Care-Related Infections Surveillance Pro- gram (VINCat) has assessed a series of indicators related to the use of antimicrobials [16–18]. In 2012, VINCat launched a program for optimizing antimicrobial use in the adult popula- tion (the VINCat hospital PROA) which it continues to coordinate today. Later, in October 2019, the VINCat pediatric PROA program was created, involving the vast majority of hospitals in Catalonia that care for pediatric patients as well as their corresponding primary care areas. The “core group” of coordinators comprises eight specialists in microbiology, pharmacy, and pediatrics, representative of the various levels of primary care and hospital care in Catalonia. Several studies have evaluated the implementation and development of pediatric an- timicrobial stewardship programs, above all in the US [19–22]. In Spain, information on the current state of pediatric PROA is scarce, both at national and at regional level [10,14,15,19]. The objective of this study is to assess the current status of pediatric PROA in the network of hospitals belonging to the VINCat pediatric PROA group, outlining the resources available for their implementation and development and describing the various activities carried out. The idea is that the results of our study should serve as a starting point for detect- ing possible areas in need of improvement, for standardizing indicators and for defining interventions able to address existing problems. 2. Results The survey was sent to 52 hospitals that serve the pediatric population. Forty-three belonged to the Catalan public health system and nine were private hospitals. Twenty-six responses were received (21 public and five private). These hospitals re- ceive 78.9% of pediatric acute hospital admissions in Catalonia, according to data provided by the Catalan health service [23]. The survey was answered by a pediatrician at 19 of the 26 hospitals and by a pharma- cist at seven. Eight hospitals (31%) were classed as level 1, ten (38%) level 2, and eight (31%) level 3. At 24 of the 26 hospitals, the pediatric service was located inside an adult hospital, while the remaining two were children’s hospitals. Fourteen hospitals (54%) reported that their pediatric service only saw patients up to 15 years of age, the maximum age for pediatric patients in primary care in Spain. The median number of pediatric beds was 25 (IQR 10-249), including the general pediatric ward, pediatric medical and surgical specialties, intermediate care, and short-stay units. The median number of PICU and NICU beds was eight (IQR 3-24) and 12 (IQR 3-45) respectively. The median admission rate in pediatric medical services in 2019 was 973 admissions (IQR 276-9435) (see Figure 1 for more details on admissions). s 2023, 12,Antibiotics x FOR PEER REVIEW 2023, 12, 250 3 of 9 3 of 10 Figure 1.

Discussion The VINCat pediatric PROA Sharing Antimicrobial Reports for Pediatric Stewardship (SHARP) survey is the first description of the current state of pediatric antimicrobial stewardship programs in hospitals in Catalonia. Due to the high representativeness of the participating centers, this study should be a useful starting point for the assessment of pediatric PROA in Catalan hospitals both now and in the future, and for detecting areas in need of improvement. The PROA should be considered as part of the institutional programs of the hospitals where they are performed [6,7]. The structure of the programs in place in the different center in this region varies widely, with the higher-level hospitals being the ones with the most developed programs. In any case, the design of the programs must meet certain minimum requirements with regard to their structure, objectives, and activities, and these will be influenced to some extent by the nature of the hospital or health area concerned, the organizational context, and the resources available. Currently, the pediatric PROA in Catalonia tend to take the form of specific actions recommended in the stewardship programs or integrated within the adult programs. In more than a quarter of the cases, the interventions and results are not reported or are unknown. As regards the composition of the teams, PROA tend to have a larger presence of pediatricians than of pharmacists and microbiologists; interestingly, at 11 hospitals (42%), the PROA teams also comprise other health professionals, especially neonatologists. The responses to the survey also reveal that the microbiological and imaging diagnostic services of our hospitals have their own computerized laboratories and perform most of the tests themselves. The main process indicators associated with the pediatric PROA are monitoring the use of antimicrobials, but only a small percentage of them regularly assess the pediatric program’s pre-established indicators. The drugs in which pharmacokinetic monitoring is most frequently performed are vancomycin and aminoglycosides, due to their wide use in neonatal and pediatric intensive care units. At almost two thirds of the hospitals, educational audits are carried out with feedback in real time; this is a positive finding, since although their effects are not as immediate as those of restrictive interventions, they are more widely accepted by prescrip- tors [6]. In addition, the vast majority of hospitals carry out activities to review and update protocols, although the frequency of their performance varies widely from center to center. Only 14 (54%) have a protocol for surgical prophylaxis, which is one of the main sources of inappropriate antibiotic use [24]. Interestingly, 16 of them (62%) prescribe antimicrobials with a specific end date, which limits the administration of unnecessary doses. Antibiotics 2023, 12, 250 7 of 10 Eleven of the hospitals (43%) do not provide any training in pediatric PROA, and only the most active and highest-level hospitals offer any advisory services. It is important to increase training in antimicrobial use at hospitals of all levels. Pediatric antimicrobial stewardship programs in Catalonia have expanded in recent years but, as elsewhere in Europe, they lag behind similar programs in place in the US [19]. Studies in the US present data from hospitals with much higher numbers of pediatric beds and of annual admissions, and so our results can hardly be compared to theirs [20]. Nevertheless, our survey shares certain similarities with the initial situation in the US in 2011 when the SHARP survey was introduced there [20]. Specifically, pediatricians devote more time to the program than pharmacists (and in our case, microbiologists as well), and in the early stages, data analysts were not heavily involved. In the coming years, the engagement of pharmacists and microbiologists needs to increase and experts in data management and analysis should also be incorporated into the PROA teams. Interestingly, only 15 hospitals (58%) included a pharmacist in the pediatric PROA team, and only 14 (54%) a microbiologist. The success of PROA programs lies in their multidisciplinary nature, built around a nucleus comprising an infectious disease specialist or a clinician who is an expert in pediatric infectious diseases, a clinical pharmacist who is an expert in antimicrobial use, and a microbiologist who is an expert in antimicrobial resistance [5–7,25]. All team members must be able to invest the time needed to be able to pursue and achieve their goals. However, the heterogeneity of the pre-established pediatric PROA indicators at the hospitals highlights the need to achieve a consensus with regard to their definition. More attention must also be paid to their monitoring. In this context, the VINCat pediatric PROA has an important role to play in creating a standardized system for recording antimicrobial consumption and antibiotic susceptibility in Catalonia. It promotes the selection and registration of specific pediatric clinical indicators and disseminates the actions and results obtained. This study has several limitations that should be mentioned. Although the survey evaluated the presence of various indicators and interventions, it did not evaluate all the ones currently in use, or the intensity or frequency of their implementation. In addition, the voluntary nature of the survey administered to the members of the PROA groups means that the results may be overestimated. In conclusion, the majority of hospitals in Catalonia have implemented the actions recommended in the pediatric antimicrobial stewardship programs, but they have not set up a specific pediatric program of their own. Concrete actions and indicators have yet to be defined, both with regard to the use of antimicrobials and with regard to clinical aspects. These programs should be provided with more resources to allow them to develop their own actions and establish specific indicators for this age group. The evolution of pediatric antimicrobial stewardship programs in our environment should be monitored over the next few years. Their growth and development will depend on the professionals themselves, the support of institutions and of the VINCat pediatric PROA group, and the resources available. 4. Material and Methods A descriptive observational study was carried out using an electronic questionnaire entitled “The VINCat pediatric PROA SHARP”, prepared from the translation and adapta- tion of the survey known as “The Sharing Antimicrobial Reports for Pediatric Stewardship (SHARPS)” [20], with the prior consent of the original authors. The multicenter SHARPS survey, conducted in the US in 2016, evaluated the implementation of the seven prerequi- sites of an antimicrobial stewardship program in the hospital setting [4,20]. The PROA program represented a sustained effort by a health institution to optimize the use of antimicrobials in hospitalized patients, with the aims of improving the clinical results of patients with infections, minimizing the adverse effects associated with the use of antimicrobials (including the emergence and spread of resistance), and guaranteeing Antibiotics 2023, 12, 250 8 of 10 the use of cost-effective treatments. The pediatric antimicrobial stewardship team at each hospital comprised pediatricians, microbiologists, and pharmacists with scientific and professional leadership capacity in the use of antimicrobials and in the understanding of bacterial resistance in the field of pediatrics [6]. Depending on the center, other health professionals such as surgeons, intensivists and nurses were also included in the team. The survey comprised 65 items assessing aspects of the pediatric antimicrobial stew- ardship programs in operation in hospitals in Catalonia. They were contacted through an email sent to all the members of the VINCat pediatric PROA group. This email contained the web link that hosted the survey. The survey remained open for two months (December 2020 and January 2021). For subsequent comparisons between centers, the hospitals were classified into three levels of complexity, with a minimum level of pediatric care defined for each one: Level 1: hospital with a low-complexity general pediatric ward and an emergency department. Level 2: regional reference hospital with a pediatric ward, an emergency department, non-urgent pediatric surgery, and a neonatal intensive care unit (NICU) for the care of newborns of ≥28 gestational weeks. Level 3: regional reference hospital offering specialized care (most pediatric special- ties), pediatric surgery, and critical care facilities (i.e., NICU and pediatric intensive care units (PICU)). The results of the survey were analyzed by the core group using the EXCEL computer program (Microsoft® Excel® 2011 version 14.7.7). The descriptive analysis of the variables present in the survey consisted of frequencies and proportions for the qualitative variables, and of medians and interquartile ranges (IQR) for the quantitative variables. Since the study did not contain personal data, it was unnecessary to obtain the ap- proval of the ethics committee or the informed consent of the members of the participating PROA teams.
