BACKGROUND: This study aims to evaluate the adherence to surgical antibiotic prophylaxis (SAP) guidelines in elective neurosurgery and assess the impact on surgical site infection (SSI) rates in a tertiary teaching hospital in Malaysia.
METHODS: A retrospective review was conducted on patients who underwent elective neurosurgical procedures from January 1, 2021, to December 31, 2021, in a 1600-bed tertiary teaching hospital. The study assessed adherence to national and hospital SAP guidelines, focusing on the choice of antibiotic, dosage, timing, and duration. Additionally, a survey was conducted among neurosurgeons to evaluate their knowledge, attitudes and practices (KAP) regarding SAP.
RESULTS: Out of 202 patients included, there was a 99% compliance rate with antibiotic choice and 69.8% with the antibiotic duration. The SSI rate was identified at 6.4%. The KAP survey highlighted a strong awareness of SAP guidelines among surgeons, albeit with variations in practice, particularly in antibiotic duration and choice of antibiotics.
CONCLUSIONS: While there is high adherence to the correct choice of antibiotic for SAP in elective neurosurgery, there are gaps in compliance with the recommended duration of antibiotic use. The study highlights the need for targeted interventions to improve adherence to SAP guidelines, which could potentially reduce the incidence of SSI in neurosurgery. Ongoing education and auditing are essential to optimize SAP practices and enhance patient outcomes in neurosurgery.

BACKGROUND: Diabetic foot ulcers in developing countries often become infected. The healthcare systems are often not equipped to conduct the culture and the sensitivity tests required for prescribing a targeted antibiotic treatment for diabetic foot infection (DFI).
METHODS: We evaluate antibiotic stewardship programmes for DFIs, at every level of health care, with an emphasis on resource-poor settings such as in Africa.
RESULTS: The management of DFI very often is adapted to the financial and practical realities of the resource-poor regions. The application of the point-of-care Gram stain of deep tissue samples is efficient, rapid, low cost and ubiquitously available. Upon the identification of the predominant pathogen in the Gram stain, a semi-quantitative preemptive antibiotic treatment can be started in accordance with the World Health Organization Aware, Watch and Restrict Essential Medicine List. This list is catered to every country and is a powerful tool. However, some basic knowledge of the local microbiological epidemiology is necessary to choose the most appropriate agent. We report our experience on using the rapidly available Gram stain for narrowing the preemptive choice of listed antibiotic agents, as an economic tool for antibiotic stewardship in DFIs.
CONCLUSIONS: In the practical and resource-saving management of DFI, the \'therapeutic\' use of Gram stains is not common in resource-rich countries but should be added to the arsenal of the general efforts for antibiotic stewardship.

UNASSIGNED: Indiscriminate use of antibiotics leads to antibiotic resistance (AMR) and results in mortality, morbidity, and financial burden. Antibiotic stewardship programs (ASPs) with education can resolve a number of barriers recognized in the implementation of successful ASPs. The aim of this study was to assess health professionals\' perceptions and status of ASPs in hospitals in 2022.
UNASSIGNED: A cross-sectional study was conducted from September 1, 2022 to October 30, 2022. A total of 181 health professionals were included, and a self-administered questionnaire was used to collect data. The status of hospitals was assessed using a checklist. The data were analyzed using SPSS version 23, and descriptive statistics and Chi-square tests (X2) at a P-value of <0.05 were used.
UNASSIGNED: Of the 181 respondents, 163 (90.1 %), and 161 (89.0 %) believed that AMR is a significant problem in Ethiopia and globally, respectively. Easy access to antibiotics 155 (85.6 %), and inappropriate use 137 (75.7 %) were perceived as key contributors to AMR. Antibiotics were believed to be prescribed/dispensed without laboratory results 86 (47.5 %), and antibiotic susceptibility patterns were not considered to guide empiric therapy 81 (44.8 %). ASP was believed to reduce the duration of hospital stays and associated costs 137 (75.7 %), and improve the quality of patient care 133 (73.5 %), whereas 151 (83.4 %), 143 (79 %), and 142 (78.5 %) suggested education, institutional guidelines, and prospective audits with feedback interventions to combat AMR in their hospitals, respectively. There were significant differences in perception among professionals based on professional category and attempts by hospitals to implement ASPs. Although ASPs were not functioning according to standard, there have been attempts to implement it in three hospitals. The issue of ASP had never been heard in general hospitals. Currently, it is feasible to implement ASPs in four hospitals.
UNASSIGNED: The status of ASP in hospitals was very poor. Despite a lack of prior knowledge on ASPs, most respondents do have a positive perception of AMR and the implementation of ASPs. Pharmacist-led prospective audits and feedback with education and institutional guidelines for empiric antibiotic use can be better implemented in hospitals. Involvement of representatives from infection prevention and control, and collaboration among hospitals in ASP implementation will help establish a strong ASP in the area.

The beta-lactam antibiotics are some of the safest and best-tolerated antibiotic agents; however, many patients have reported allergies against penicillin. All beta-lactam antibiotics are only restrictively prescribed for these patients and alternative antibiotics are increasingly given, which carries the risk of negative clinical results and socioeconomic sequelae; however, over 95% of patients who reported an allergy to penicillin show a negative result in the allergy tests for penicillin and this antibiotic can safely be prescribed. The use of sensitive and specific instruments for identification of false penicillin allergies should be an important topic within the framework of antibiotic stewardship. Anesthesists can play a central role in the reduction of the enormous individual and public health burden associated with the classification of penicillin allergy by taking an appropriate medical history and a risk stratification for the identification of patients with a penicillin allergy. This overview article presents a possible delabelling algorithm within the framework of the clarification of a beta-lactam antibiotic allergy. The focus is on a structured allergy anamnesis using the penicillin allergy, five or fewer years ago, anaphylaxis/angioedema, severe cutaneous adverse reaction (SCAR) and treatment required for allergy episode (PEN-FAST) score.
UNASSIGNED: Die β‑Lactam-Antibiotika gehören zu den sichersten und am besten verträglichen Antibiotika. Viele Patienten berichten allerdings von Allergien gegen Penicillin. Diesen Patienten werden sämtliche β‑Lactam-Antibiotika nur eingeschränkt verordnet und vermehrt Alternativantibiotika gegeben, was die Risiken negativer klinischer und sozioökonomischer Folgen birgt. Jedoch weisen über 95 % der Patienten, die von einer Penicillinallergie berichten, einen negativen Befund im Penicillin-Allergietest auf und können dieses Antibiotikum sicher erhalten. Die Verwendung sensibler und spezifischer Instrumente zur Identifizierung von „falschen“ Penicillinallergien sollte ein wichtiges Thema im Rahmen der Antibiotic Stewardship sein. Durch eine angemessene Anamnese und Risikostratifizierung zur Identifizierung von Patienten mit einer Penicillinallergie können Anästhesistinnen und Anästhesisten eine zentrale Rolle bei der Reduktion der enormen individuellen und öffentlichen Gesundheitsbelastung im Zusammenhang mit der Bezeichnung Penicillinallergie einnehmen. In dieser Übersichtsarbeit wird ein möglicher Delabeling-Algorithmus im Rahmen der Abklärung einer β‑Lactam-Antibiotika-Allergie präsentiert. Der Fokus liegt auf einer strukturierten Allergieanamnese mithilfe des Scores „Penicillin allergy, within last five years, anaphylaxis/angioedema, severe cutaneous adverse reaction (SCAR) and treatment required for allergy episode“ (PEN-FAST).

BACKGROUND: Ten % of the population is labeled as allergic to penicillin(s), when in fact 90% of these labels are inappropriate. Recent studies have shown that inpatient de-labelling by a direct drug challenge (dDC) is safe in low-risk patients. However, there is a need for outpatient and non-allergist de-labelling.
OBJECTIVE: To assess the safety of de-labelling low-risk adults by means of dDC in primary care.
METHODS: We searched MEDLINE, EMBASE and the Conchrane Library databases, from inception to March 15, 2022 (updated June 5, 2023) for studies performing dDC in adults in primary care or other outpatient settings. Two researchers independently screened studies for eligibility. The data extraction and critical appraisal was performed by one reviewer and we pooled the results in a meta-analysis.
RESULTS: Out of 2,138 results, 12 studies (1070 participants) were eligible for inclusion. Three studies evaluated de-labelling in primary care and 9 studies in an outpatient hospital setting. There were no critical adverse events during dDC. No reaction occurred in 97.13% of the 1070 patients, who previously labeled as penicillin-allergic, and were safely de-labelled. Ten patients (<1%) developed an immediate reaction: three had self-limiting reactions, and seven needed antihistaminics, steroids, epinephrine and/or salbutamol.
CONCLUSIONS: No serious allergic reactions are observed during direct amoxicillin challenge in adults in an outpatient setting. However, with the exception of one recent report, these studies are of low to moderate quality. Non-specialist de-labelling is promising but further research is required on correct risk stratification and safety assessment in large cohort studies evaluating dDC in primary care.

OBJECTIVE: To assess whether a two-phase intervention was associated with improvements in antibiotic prescribing among non-hospitalized children with community-acquired pneumonia.
METHODS: In a large health care organization, a phase one intervention was implemented in September 2020 directed at antibiotic choice and duration for children 2 months through 17 years of age with pneumonia. Activities included clinician education and implementation of a pneumonia-specific order set in the electronic health record (EHR). In October 2021, a second phase comprised additional education and order set revisions. A narrow spectrum antibiotic (eg, amoxicillin) was recommended in most circumstances. EHR data were used to identify pneumonia cases and antibiotics ordered. Using interrupted time series analyses, antibiotic choice and duration after phase one (September 2020 to September 2021) and after phase two (October 2021 to October 2022) were compared with a pre-intervention pre-pandemic period (January 2016 to early March 2020).
RESULTS: Overall, 3570 cases of community-acquired pneumonia were identified: 3246 cases pre-intervention, 98 post-phase-one, and 226 post-phase-two. The proportion receiving narrow spectrum monotherapy increased from 40.6% pre-intervention to 68.4% post-phase-one to 69.0% post-phase-two (p<0.001). For children with an initial narrow spectrum antibiotic, duration decreased from pre-intervention (mean duration 9.9 days, standard deviation [SD] 0.5 days) to post-phase-one (mean 8.2, SD 1.9) to post-phase-two (mean 6.8, SD 2.3) periods (p<0.001).
CONCLUSIONS: A two-phase intervention with educational sessions combined with clinical decision support was associated with sustained improvements in antibiotic choice and duration among children with community-acquired pneumonia.

OBJECTIVE: To identify the preferred choices of antimicrobials by veterinarians for addressing infectious diseases in Golden Retrievers across the US.
METHODS: 3,044 Golden Retrievers enrolled in the Golden Retriever Lifetime Study.
METHODS: Demographic and veterinary visit data were retrieved from the Morris Animal Foundation Golden Retriever Lifetime Study, following 3,044 Golden Retrievers spanning from 2012 to 2020 collected through questionnaires. The R Studio program was used to clean and analyze the data in which the most common diagnoses were evaluated along with the most frequently used antimicrobials stratified by geographical region within the US.
RESULTS: The most common diagnoses reported and treated with antimicrobials were otitis externa, diarrhea/gastritis, hot spots, and bladder infections. Otitis externa was the most frequently reported medical diagnosis as well as prescribed with antibiotics. The Southern region reported the most antimicrobial use, followed by the Midwest and Northeast. Of the total reported antibiotics prescribed for infectious disease, aminoglycosides were the most frequent (370/1,874 [19.74%]) followed by first-generation cephalosporins, nitroimidazoles, and penicillins.
CONCLUSIONS: More effort in the prevention of otitis externa in Golden Retrievers may reduce overall antimicrobial usage and promote effective antimicrobial stewardship to combat further antimicrobial resistance.

The enormous increase in antibiotic resistance and the limited spectrum of new, effective antibiotics are the reasons why we should think about a rational approach to anti-infective therapy. The excessive and non-indicated use of antibiotics while treating critically ill patients can be found quite often in clinical practice. Antibiotic therapy is usually indicated empirically, or it is only based on therapeutic indecision, not just in ICU patients. The antibiotics are administered before taking a sample for microbiological analysis or there is no therapy adjustment based on the laboratory findings. The solution lies in antibiotic stewardship, which is the way to ensure that antibiotics will be sufficiently effective in years to come.
