Gender and Racial Differences in the Provision of Palliative Care Services Among Critically ill Necrotizing Fasciitis and Septic Shock Geriatric Patients: Analysis of a Nationwide Database in the United States.

Introduction: Necrotizing fasciitis (NF) and sepsis shock (SS) are both severe and life-threatening conditions requiring specialized care, including palliative care (PC), to optimize comfort. However, data on the utilization of PC in this population, including racial and gender differences, are limited. Methods: We used the National Inpatient Sample (NIS) database from 2016 to 2020 to extract data on patients with NF and SS as well as PC utilization. Chi-squared tests and multivariate linear regression models were utilized to analyze relationships between categorical and continuous variables, respectively. Multivariable logistic regression was used to determine adjusted odds ratios (aORs) and 95% confidence intervals (CI) for various outcomes among various gender and racial groups. Mann-Kendall trend test was used to assess mortality trends over time. Results: Among the 11,260 patients with NF and SS, 2,645 received PC whereas 8,615 did not. Female patients had significantly higher odds of receiving PC versus males (aOR: 1.42, 95% CI 1.27-1.58). No significant racial differences in PC utilization were observed. Patients receiving PC had higher odds of in-hospital mortality (aOR: 1.18, 95% CI 1.03-1.35). No significant trend in in-hospital deaths was observed over the study period. PC was associated with significantly shorter length-of-stay and lower costs. Conclusion: Our study provides comprehensive insights, and identifies gender differences in PC utilization in NF and SS patients. Further research must aim to refine delivery strategies and address potential differences in PC.

Impact of next-generation sequencing on antimicrobial treatment in immunocompromised adults with suspected infections.

BACKGROUND: Prompt pathogen identification can have a substantial impact on the optimization of antimicrobial treatment. The objective of the study was to assess the diagnostic value of next-generation sequencing (NGS) for identifying pathogen and its clinical impact on antimicrobial intervention in immunocompromised patients with suspected infections. METHODS: This was a retrospective study. Between January and August 2020, 47 adult immunocompromised patients underwent NGS testing under the following clinical conditions: 1) prolonged fever and negative conventional cultures; 2) new-onset fever despite empiric antimicrobial treatment; and 3) afebrile with suspected infections on imaging. Clinical data, including conventional microbial test results and antimicrobial treatment before and after NGS, were collected. Data were analyzed according to documented changes in antimicrobial treatment (escalated, no change, or de-escalated) after the NGS results. RESULTS: The median time from hospitalization to NGS sampling was 19 d. Clinically relevant pathogens were detected via NGS in 61.7% of patients (29/47), more than half of whom suffered from fungemia (n=17), resulting in an antimicrobial escalation in 53.2% of patients (25/47) and antimicrobial de-escalation in 0.2% of patients (1/47). Antimicrobial changes were mostly due to the identification of fastidious organisms such as Legionella, Pneumocystis jirovecii, and Candida. In the remaining three cases, NGS detected clinically relevant pathogens also detected by conventional cultures a few days later. The antimicrobial treatment was subsequently adjusted according to the susceptibility test results. Overall, NGS changed antimicrobial management in 55.3% (26/47) of patientst, and conventional culture detected clinically relevant pathogens in only 14.9% of patients (7/47). CONCLUSION: With its rapid identification and high sensitivity, NGS could be a promising tool for identifying relevant pathogens and enabling rapid appropriate treatment in immunocompromised patients with suspected infections.

Documenting the indication for antimicrobial prescribing: A retrospective observational study of long-term care homes.

BACKGROUND: Overuse of antimicrobials in residents of long-term care homes is common and can result in harm. Antimicrobial stewardship interventions are needed in the long-term care (LTC) homes setting to improve the appropriate use of antimicrobials. Previous literature has highlighted the importance of documenting antimicrobial indication as a strategy that contributes to improve antimicrobial use; however, there is a lack of evidence in LTC homes. This study examines the prevalence, clarity, and facility-level variability of antibiotic indication documentation in this setting. METHODS: This is an observational retrospective study of oral antibiotic prescriptions dispensed to 218 homes between January 1, 2021 and December 31, 2022 in Ontario, Canada. Indication was obtained from reviewing antibiotic prescription data. Clarity was determined by comparing documented indication to the National Antimicrobial Prescribing Survey (NAPS). Descriptive analysis was performed to examine the prevalence and clarity of indication documentation. Funnel plots were generated to examine variability in prevalence of indication documentation and clarity at the home level. RESULTS: Overall, 22.9% (7998/34,867) of prescriptions had an indication documented. The proportion of indications that were clear was 37% (2984/7998). The most common indications were for urinary (45%), skin and soft tissue (19.9%) and respiratory infections (15.0%). At the home level, the median prevalence of indication was 19.6% (interquartile range [IQR]: 10.8%-31.4%) and median prevalence of clear indications was 35.1% (IQR: 23.8%-42.9%). Funnel plots revealed substantial variability in indication prevalence with 46.3% of homes falling outside of 99% limits but minimal variability in indication clarity between homes with only 8.7% of homes outside of 99% control limits. CONCLUSIONS: There is an opportunity to increase both the prevalence and clarity of antibiotic prescriptions in LTC homes. Future work should focus on determining how best to support prescription indication documentation in this setting with consideration being given to prescription workflow and most common antibiotic prescription indications.

An evaluation of risk factors for readmission in patients receiving outpatient parenteral antimicrobial therapy.

Background: Outpatient parenteral antimicrobial therapy (OPAT), when required, is beneficial to patients and healthcare systems by reducing hospital length-of-stay, providing cost savings, and improving patient satisfaction. Objectives: The purpose of this study is to determine readmission rates and associated risk factors in patients receiving OPAT at home. Methods: This retrospective study included hospitalized patients 15 years and older who were discharged on intravenous antimicrobial therapy via OPAT at home between January 2018 and December 2019. Patients receiving antimicrobials at a skilled nursing facility, long-term acute care, or dialysis center, and those who began OPAT at home directly from the outpatient setting were excluded. The primary outcome of this study was all-cause 30-day readmission rate. Secondary outcomes included 90-day readmission rate, rates of complications related to OPAT, emergency department visits during OPAT, and predictors of all-cause 30-day readmission through a logistic regression analysis. Results: Two hundred individual patients were included in the analysis; 60% were male and the mean age was 49 years. The most common indications for OPAT at home were bone and joint infection (52%) and bacteremia (26%). Forty patients (20%) experienced an unplanned, all-cause 30-day readmission, with a total of 48 readmission events. Of the 40 patients who were readmitted within 30 days, 20 (50%) were due to non-OPAT related reasons. Sixty patients (30%) experienced an OPAT-related complication, and chronic kidney disease was found to be an independent predictor of readmission (OR: 2.8, 95% CI: 1.0-7.6). Conclusions: Patients receiving OPAT at home are at increased risk for early hospital readmission, but it is often due to reasons not associated with OPAT. Patients with chronic kidney disease beginning OPAT at home should be closely monitored after discharge.

Antimicrobial Defined Daily Dose in Neonatal Population: Validation in the Clinical Practice.

BACKGROUND: Currently, there is no validated method for estimating antimicrobial consumption in the neonatal population, as it exists for adults using Defined Daily Doses (DDD). In neonatology, although there are different methods, each one with advantages and disadvantages, there is no unified criterion for use. The aim of this study is to validate the neonatal DDD designed as a new standardised form of antimicrobial consumption over this population. METHODS: The validation of the neonatal DDD, Phase II of the research project, was carried out through a descriptive observational study. Periodic cut-offs were performed to collect antimicrobial prescriptions of neonates admitted to the neonatology and intensive care units of nine Spanish hospitals. The data collected included demographic variables (gestational age, postnatal age, weight and sex), antimicrobial dose, frequency and route of administration. The selection of the optimal DDD value takes into account power value, magnitude obtained from the differences in the DDD, statistical significance obtained by the Wilcoxon test and degree of agreement in the stipulated doses. RESULTS: Set of 904 prescriptions were collected and finally 860 were analysed based on the established criteria. The antimicrobials were mostly prescribed in the intensive care unit (63.1%). 32 different antimicrobials were collected, and intravenous administration was the most commonly used route. Neonatal DDD were defined for 11 different antimicrobials. A potency > 80% was obtained in 7 antibiotics. The 57.1% of the selected DDD correspond to phase I and 21.4% from phase II. CONCLUSION: DDD validation has been achieved for the majority of intravenously administered antimicrobials used in clinical practice in the neonatal population. This will make it possible to have an indicator that will be used globally to estimate the consumption of antimicrobials in this population, thus confirming its usefulness and applicability.

Abdominal fascia dehiscence: is there a connection to a special microbial spectrum?

INTRODUCTION: Acute fascia dehiscence (FD) is a threatening complication occurring in 0.4-3.5% of cases after abdominal surgery. Prolonged hospital stay, increased mortality and increased rate of incisional hernias could be following consequences. Several risk factors are controversially discussed. Even though surgical infection is a known, indisputable risk factor, it is still not proven if a special spectrum of pathogens is responsible. In this study, we investigated if a specific spectrum of microbial pathogens is associated with FD. METHODS: We performed a retrospective matched pair analysis of 53 consecutive patients with an FD after abdominal surgery in 2010-2016. Matching criteria were gender, age, primary procedure and surgeon. The primary endpoint was the frequency of pathogens detected intraoperatively, the secondary endpoint was the occurrence of risk factors in patients with (FD) and without (nFD) FD. RESULTS: Intraabdominal pathogens were detected more often in the FD group (p = 0.039), with a higher number of Gram-positive pathogens. Enterococci were the most common pathogen (p = 0.002), not covered in 73% (FD group) compared to 22% (nFD group) by the given antibiotic therapy. Multivariable analysis showed detection of Gram-positive pathogens, detection of enterococci in primary laparotomy beside chronic lung disease, surgical site infections and continuous steroid therapy as independent risk factors. CONCLUSION: Risk factors are factors that reduce wound healing or increase intra-abdominal pressure. Furthermore detection of Gram-positive pathogens especially enterococci was detected as an independent risk factor and its empirical coverage could be advantageous for high-risk patients.

Antibiotic usage patterns in exotic pets: A study in Curitiba, Paraná, Brazil.

Background: The link between the reckless use of antimicrobials with the increasing development of multidrug-resistant strains of antibiotics is well established. To control the spread of antimicrobial resistance (AMR), action plans, recommendations and guidelines on the prudent use of antibiotics have been developed for food-producing animals and companion animals but appear to be lacking in exotic pets due to the scarcity of data and information on the use of antibiotics in these species. Aim: The purpose of this study is to bring qualitative and quantitative data regarding the use of antimicrobials in exotic pets in a veterinary center in southern Brazil, seeking to measure the consumption of these animals to determine and guide future actions to combat AMR. Methods: A retrospective observational study was conducted by surveying 2,190 open care records in a specialized clinic of wildlife medicine in 2018. Data evaluation was performed in a descriptive, qualitative, and quantitative way, and the analysis of antimicrobial consumption was performed by calculating the daily dose/g of animal ml/day/kg by animal order, condition and active principle, adaptation to DDDVet. For statistical analysis, Levene´s, ANOVA followed by Tukey´s tests were used. Results: Approximately 57% (1250/2190) of the visits made use of one or more antimicrobials in the treatment of animals referred to the clinic. Of these, 67% (n = 839) were birds, 26% (n = 327) were mammals, and 7% (n = 84) were reptiles. In 2018, the total consumption of antimicrobials prescribed was 2.21 l for a total biomass of 129.24 kg. The relation between the dosages of the main antimicrobials used and the conditions treated showed that there is no variation between the treatments by disease and by animal class, due to the great variation within each group. Conclusion: The antimicrobial prescription in exotic pets requires a multifaceted and dynamic approach applied to safeguard the efficacy of the antimicrobials, optimizing consumption, minimizing the emergence of AMR and other possible adverse effects, and considering the physiological differences present within each species. The doses between the different classes and conditions do not obtain a significant difference, reflected in a possible nonstandardization of the dosages used, requiring further investigation of the recommended dosages for each animal species, avoiding the over or underdosing of these drugs. It is worth highlighting that professionals must always make rational use of antimicrobials in these species.

The Role of Clinical Pharmacists in Antimicrobial Stewardship Programs (ASPs): A Systematic Review.

Antimicrobial resistance (AMR) is a major global health threat, increasing deaths and healthcare costs. Antimicrobial stewardship programs (ASPs) have been implemented to optimize antibiotic use and curb resistance. This systematic review aimed to summarize evidence on the role and impact of pharmacists in hospital ASPs. A comprehensive literature search was conducted across databases to identify relevant studies published from 2016 to 2023. Twenty-four studies met the inclusion criteria, comprising global observational and randomized clinical trials. Pharmacists performed various stewardship activities, including prospective audits, formulary management, de-escalation, guideline development, and education. Pharmacist-led interventions significantly improved antibiotic prescribing, reduced unnecessary antibiotic use, optimized therapy, and enhanced outcomes. Multiple studies found that pharmacist reviews decreased the time to optimal antibiotics and improved guideline compliance without affecting readmissions or revisits. De-escalation programs safely reduced antibiotic duration and length of stay. Acceptance rates for recommendations were high. Pharmacist stewardship curbed overall antibiotic use, costs, and duration across hospital departments, leading to savings. While most studies showed positive impacts, fewer detected significant changes in resistance or mortality over short periods. More research is needed, but current evidence demonstrates that pharmacists play critical roles in ASPs, leading to improved antibiotic use and patient outcomes. These findings support integrating pharmacists into stewardship activities, significantly extending programs to ambulatory settings.

Diagnostic Yield and Impact on Antimicrobial Management of 16S rRNA Testing of Clinical Specimens.

16S rRNA gene sequencing is increasingly used in clinical practice for bacterial identification of clinical specimens. However, studies on its applicability to direct clinical specimens are limited. Here, we studied the diagnostic yield and impact of 16S rRNA gene sequencing from direct clinical specimens on antimicrobial management. Adult inpatients whose attending physician requested 16S rRNA gene sequencing and corresponding bacterial culture from a direct clinical specimen between January and December 2021 in a university hospital were prospectively included in this study. A total of 434 specimens from 374 patients were requested. Of these, 253 (58.3%) specimens were collected from patients whose final diagnosis indicated a bacterial infection, whereas 181 (41.7%) specimens were from nonbacterial infections. Using the final diagnosis as a "gold standard," the sensitivity and specificity of 16S rRNA gene sequencing were 38.3% and 93.9%, respectively. Among the bacterial infection cases, the proportion of 16S rRNA gene sequencing-positive and culture-positive cases was 32.4%, and the proportion of sequencing-positive and culture-negative cases was 5.9%. The impact on antimicrobial management was evident in 10 (2.3%) specimens, which all resulted in the continuation of antibiotics. The impact on antimicrobial management was highest in skin and soft tissue infections, followed by bone and joint infections. In this study, the long turnaround time of 16S rRNA gene sequencing of clinical specimens was a limiting factor. In conclusion, the overall diagnostic yield of 16S rRNA gene sequencing in bacterial infection cases was fair, being useful in selected cases. Restrictions on test requests may improve test utilization in this setting. IMPORTANCE 16S rRNA gene sequencing has been increasingly used in clinical practice. Using the final diagnosis as a gold standard, the sensitivity of 16S rRNA gene sequencing was fair. In the setting with no 16S rRNA gene sequencing test ordering restrictions, only small percentages of the test results had an impact on antimicrobial management. Restrictions on test requests should be developed to maximize the benefit of the test.

Consumption of Antibiotics in Primary Care Setting before and during COVID-19 Pandemic in Republic of Srpska, Bosnia and Herzegovina.

The pandemic of COVID-19 has brought many changes in health care systems at all levels of health care. The increase in the number of cases of COVID-19 has led to overuse and misuse of antibiotics.The aim of this study was to compare the consumption of antibiotics for systemic use in outpatients in the Republic of Srpska (RS), before and during the first year of the COVID-19 pandemic, as well as the association between antibiotic consumption and the rate of incidence and mortality of COVID-19. The total consumption of the antibiotics for systemic use (J01) in outpatients in the Republic of Srpska during 2019 was 19.40 DDD/TID, with an increase to 30.80 DDD/TID in 2020.Significantly higher use of penicillin (10.58 ± 11.01 DDD/TID in 2019 vs. 17.10 ± 13.63 DDD/TID in 2020), cephalosporins (2.68 ± 1.90 DDD/TID in 2019 vs. 5.93 ± 2.77 DDD/TID in 2020) and macrolides (2.14 ± 2.22 DDD/TID in 2019 vs. 3.40 ± 3.44 DDD/TID in 2020) was observed during the pandemic period. It is necessary to improve the prescribing practice of antibiotics at the primary health care level, public awareness about rational use of antibiotics, as well as the current antibiotic stewardship programs and control their implementation.

Knowledge, Attitudes and Practices of Parents and Pediatricians Regarding Antibiotic Use among Children: Differences in Relation to the Level of Education of the Parents in the Republic of Srpska Bosnia and Herzegovina.

Antibiotics are often misused, especially for the treatment of upper respiratory tract infections (URTIs) in children, where their use is unnecessary and leads to antimicrobial resistance. This study sought to explore the knowledge, attitudes and practices (KAP) of parents and pediatricians on the use of antibiotics among children and whether the level of education of parents has an impact on their KAP. The research was carried out among 1459 parents of children under 6 years of age and among 18 pediatricians. Sixty percent of pediatricians (61.1%) were prescribed antibiotics daily in their practice. Most of the surveyed parents (98.4%) state that doctors are their main source of information when deciding on the use of antibiotics in the treatment of their children. Parents with a higher level of education use television less often as a source of information when making this decision compared to parents with a lower level of education (p = 0.039, i.e., p = 0.003). The majority of parents (80.7%) knew that Panklav (amoxicillin/clavulanic acid) is an antibiotic, while 52.5% identified Pancef (cefixime) as an antibiotic. Parents with a higher level of education correctly identified antibiotics significantly more often (p < 0.001). This study shows that in the Republic of Srpska, parents have adequate knowledge about antibiotics, especially those with a higher level of education, who show better KAP when it comes to antibiotic use.

Efficacy of Cefazolin versus Ceftriaxone for Extremity Open Fracture Management at a Level 1 Trauma Center.

Background: Antibiotic agents have been shown to improve outcomes in open extremity fractures. The first-generation cephalosporins, which are used most often, are often under-dosed based on weight and recommended frequency. Ceftriaxone offers a broader coverage and a decreased frequency of administration. Our institution began utilizing ceftriaxone for open fracture management in 2017 to address those concerns. Objective: To examine the efficacy of cefazolin versus ceftriaxone for open fracture management of extremity trauma. Patients and Methods: Retrospective study from 2015-2019 of patients who sustained open extremity fractures. Patients were stratified by antibiotic administered and Gustilo-Anderson grade. Outcomes included non-union/malunion, superficial surgical site infection (SSI), deep SSI, osteomyelitis, re-operation after index hospital visit, re-admission due to prior injury, limb loss, and death. Subgroup analysis stratified each antibiotic group by Gustilo-Anderson grade 1 or 2 and grade 3. Results: Data was collected from 2015 to 2019. Of the 1,149 patients, 619 patients met inclusion criteria. Three hundred fifty-five patients received cefazolin and 264 patients received ceftriaxone. There were no statistically significant differences between groups on specified outcomes. No statistically significant differences existed during subgroup analysis for the specified outcomes. Multivariable analysis demonstrated increased Gustilo-Anderson grade increased risk of infectious outcome. Conclusions: Ceftriaxone is a safe and effective alternative for open fracture extremity management that offers the advantage of 24-hour dosing and single antibiotic coverage for grade 3 open fractures. It does not increase infectious complications and offers benefits of resource efficiency.

Lessons from an Educational Invasive Fungal Disease Conference on Hospital Antifungal Stewardship Practices across the UK and Ireland.

Invasive fungal disease (IFD) is a growing health burden. High mortality rates, increasing numbers of at-risk hosts, and a limited availability of rapid diagnostics and therapeutic options mean that patients are increasingly exposed to unnecessary antifungals. High rates of prescriptions promote patient exposure to undue toxicity and drive the emergence of resistance. Antifungal stewardship (AFS) aims to guide antifungal usage and reduce unnecessary exposure and antifungal consumption whilst maintaining or improving outcomes. Here, we examine several AFS approaches from hospitals across the UK and Ireland to demonstrate the benefits of AFS practices and support the broader implementation of AFS as both a necessary and achievable strategy. Since the accuracy and turnaround times (TATs) of diagnostic tools can impact treatment decisions, several AFS strategies have included the development and implementation of diagnostic-driven care pathways. AFS informed treatment strategies can help stratify patients on a risk basis ensuring the right patients receive antifungals at the optimal time. Using a multidisciplinary approach is also key due to the complexity of managing and treating patients at risk of IFD. Through knowledge sharing, such as The Gilead Antifungal Information Network (GAIN), we hope to drive practices that improve patient management and support the preservation of antifungals for future use.

Impact of Next-Generation Sequencing Cell-free Pathogen DNA Test on Antimicrobial Management in Adults with Hematological Malignancies and Transplant Recipients with Suspected Infections.

Infections in adult patients with hematological malignancies (HM) and stem cell transplant (SCT) recipients are a significant cause of morbidity and mortality. A timely diagnosis of infections can have a major impact on outcomes. Tools that help rule out infectious causes of fever can decrease antibiotic use, toxicities, hospitalization costs, and potentially decrease antibiotic resistance in the long term. We retrospectively evaluated the ability of cell-free DNA next-generation sequencing (NGS) testing in the timely identification of pathogenic microorganisms and its impact on the antimicrobial management of immunocompromised patients with hematologic malignancies. In the period between 2018 to 2020, 95 samples were reviewed, of which 31 adult patients (32 tests) had hematologic malignancies or were recipients of SCT. The NGS tests were performed in the following patients: (a) patients with prolonged fever and negative conventional tests, (b) persistent fever despite positive conventional test and appropriate antimicrobials, and (c) fever-free patients with imaging suspicious for infection. The median time from fever to NGS sampling was 5 days (range, 1-28). The median time to NGS results was 2 days (range, 1-6). The NGS resulted in an escalation of antibiotics in 28% of cases (9/32) and de-escalation of antibiotics in 31% of cases (10/32). Overall, NGS testing changed management in nearly 59% (19/32) of patients. The sensitivity and specificity of NGS to detect clinically significant infection was 80% and 58%, respectively. The test identified uncommon and difficult to diagnose organisms such as Nocardia, Legionella, Toxoplasma and Pneumocystis jirovecii resulting in rapid antimicrobial interventions. In conclusion, in patients with HM or SCT recipients, microbial cell-free DNA sequencing allowed rapid and actionable treatment. This strategy can target appropriate antibiotic use, avoid overtreatment, and potentially decrease the hospital length-of-stay.

Mapping the Implementation of a Clinical Pharmacist-Driven Antimicrobial Stewardship Programme at a Tertiary Care Centre in South India.

In many parts of the world, including in India, pharmacist roles in antimicrobial stewardship (AMS) programmes remain unexplored. We describe the evolution and effect of the role of adding clinical pharmacists to a multidisciplinary AMS at a tertiary care teaching hospital in Kerala, India. Through effective leadership, multidisciplinary AMS (February 2016) and antitubercular therapy (ATT) stewardship programmes (June 2017) were established. Clinical pharmacists were introduced as core members of the programmes, responsible for the operational delivery of key stewardship interventions. Pharmacy-led audit and feedback monitored the appropriateness of antimicrobial prescriptions and compliance to AMS/ATT recommendations. Between February 2016 and January 2017, 56% (742/1326) of antimicrobial prescriptions were appropriate, and 54% (318/584) of recommendations showed compliance. By the third year of the AMS, appropriateness increased to 80% (1752/2190), and compliance to the AMS recommendations to 70% (227/325). The appropriateness of ATT prescriptions increased from a baseline of 61% (95/157) in the first year, to 72% (62/86, June 2018-February 2019). The compliance to ATT recommendations increased from 42% (25/60) to 58% (14/24). Such a model can be effective in implementing sustainable change in low- and middle-income countries (LMICs) such as India, where the shortage of infectious disease physicians is a major impediment to the implementation and sustainability of AMS programmes.

Antifungal stewardship in a tertiary care paediatric hospital: the PROAFUNGI study.

BACKGROUND: The increasing use of antifungal drugs (AF) in children and the concern for related adverse events and costs has led to the development of specific AF stewardship programmes (AFS). Studies in adult patients have shown improvements in AF prescription and usage after implementation, but paediatric data are scant. The aim of this PROAFUNGI study was to describe the use and appropriateness of AF in a high complexity paediatric centre. METHODS: Observational, prospective, single-centre, modified point-prevalence study (11 surveys, July-October 2018), including paediatric (< 18 years) patients receiving at least one systemic AF. Prescriptions were evaluated by the AFS team. RESULTS: The study included 119 prescriptions in 55 patients (53% males, median age 8.7 years [IQR 2.4-13.8]). The main underlying condition was cancer (45.5% of patients; HSCT in 60% of them); and the first indication for AF was prophylaxis (75 prescriptions, 63.2%). Liposomal amphotericin B was used most commonly (46% prescriptions), mainly as prophylaxis (75%). Among the 219 evaluations, 195 (89%) were considered optimal. The reason for non-optimal prescriptions was mostly lack of indication (14/24), especially in critical patients with ventricular assist devices. The use of AF without paediatric approval accounted for 8/24 inappropriate prescriptions. CONCLUSIONS: A high rate of AF appropriateness was found for the children's hospital as a whole, in relation with a well-established AFS. Nonetheless, the identification of specific areas of improvement should guide future actions of the AFS team, which will focus mainly on prophylaxis in critically ill patients receiving circulatory assistance and the use of non-approved drugs in children.

Epidemiology and Risk Factors for Superficial Surgical Site Infections after Appendectomy for Acute Appendicitis: A Secondary Data Analysis.

Background: The identification of risk factors for superficial surgical site infections (SSSIs) associated with appendectomy is paramount in the management of patients with acute appendicitis (AA). Methods: This study was a secondary data analysis from a prospective multi-center observational study. It included all consecutive hospitalized patients with AA who underwent appendectomy and were monitored for complications at 30 days after the intervention. A case-control approach was used to evaluate risk factors associated with the occurrence of SSSI. Results: Among 2,667 patients, 156 (5.8%) developed an SSSI. The series included 1,449 males (54.3%) and 1,218 females with a median age of 29 years (interquartile range [IQR] 20-45 years). Antimicrobial therapy within the previous 30 days was reported by 170 patients (6.4%), and a C-reactive protein concentration (CRP) >50 mg/L was observed in 609 (22.8%). A total of 960 patients (36.0%) underwent open surgery, 1,699 (63.7%) laparoscopic surgery, and 8 (0.3%) another surgical intervention. In 2,575 patients (95.6%), a pathological appendix was detected during the operation. In 776 patients (29.1%), an intra-operative abdominal drain (IAD) was placed; 125 patients (4.7%) were admitted to the intensive care unit. The median hospital length of stay was 3 days (IQR 2-5 days). The overall mortality rate was 0.11%. Multinomial logistic regression analysis of risk factors demonstrated that statistically significant risk factors independently associated with the occurrence of SSSIs were antimicrobial therapy within the previous 30 days, CRP >50 mg/L, open surgical procedures, presence of IAD, and intra-operative findings of complex appendicitis. Conclusions: Knowledge of five easily recognizable variables, assessable at hospital admission or as soon as the surgical intervention is concluded, might identify patients with a greater risk of developing an SSSI.

E-Health Tools to Improve Antibiotic Use and Resistances: A Systematic Review.

(1) Background: e-Health tools, especially in the form of clinical decision support systems (CDSSs), have been emerging more quickly than ever before. The main objective of this systematic review is to assess the influence of these tools on antibiotic use for respiratory tract infections. (2) Methods: The scientific databases, MEDLINE-PubMed and EMBASE, were searched. The search was conducted by two independent researchers. The search strategy was mainly designed to identify relevant studies on the effectiveness of CDSSs in improving antibiotic use, as a primary outcome, and on the acceptability and usability of CDSSs, as a secondary outcome. (3) Results: After the selection, 22 articles were included. The outcomes were grouped either into antibiotics prescription practices or adherence to guidelines concerning antibiotics prescription. Overall, 15 out of the 22 studies had statistically significant outcomes related to the interventions. (4) Conclusions: Overall, the results show a positive impact on the prescription and conscientious use of antibiotics for respiratory tract infections, both with respect to patients and prescribing healthcare professionals. CDSSs have been shown to have great potential as powerful tools for improving both clinical care and patient outcomes.

Analysis of the impact of antimicrobial management and rational use of antibiotics.

OBJECTIVE: The scientific antimicrobial management strategy (AMS) was used to standardise the clinical use of antibiotics and optimise the anti-infection treatment protocol. METHODS: By formulating antibiotic use indicators and policy interventions, carrying out prescription audits and drug analysis by pharmacists, and establishing an early warning mechanism for bacterial drug resistance, we formed a long-term and scientific antimicrobial management strategy. RESULTS: From 2012 to 2017, the clinical antibiotics use indicators appeared to trend downward. The rate of antibiotic use in outpatients, the rate of antibiotic use in hospitalised patients, and the antimicrobial use density decreased by 40.36%, 20.93%, and 10.71%, respectively, and the per capita drug cost of antibiotics in outpatients and inpatients decreased. The microbiological susceptibility test rate of antibiotics in hospitalised patients increased each year, and the resistance rate of the main detected bacteria did not significantly increase in the last 6 years. In the evaluation of rational drug use, the use of antibiotics has become more reasonable and standardised, and irrational drug use has been significantly reduced, but we still need to strengthen the optimisation of treatment prescription. CONCLUSIONS: Scientific management can promote the rational use of antibiotics, reduce the expense of drug use and slow the development of drug resistance, but we need to further optimise the prescription of antibiotics to improve the level of drug treatment.
