Knowledge and Attitudes of Female Adolescents on the Causes, Effects and Prevention of Vaginal Candidiasis in the Adenta Municipality of the Greater Accra Region of Ghana

Introduction: Among every four women, at least, three of them experience vaginal candidiasis caused by Candida albicans. People with dysfunctional immune system such as the aged, very young children, altered pH and sugar content in vaginal secretions as a result of pregnancy, HIV/AIDS, diabetes, hormonal fluctuations, smoking, black race, oral-contraceptives, obesity and use of broad-spectrum antibiotics increases the frequency to acquiring infection and are therefore vulnerable to fungal infections. Poor hygiene, chemical irritants and the presence of foreign body in the vagina can also cause vaginal candidiasis Objective: This study sought to access the knowledge and attitudes regarding causes, effects and prevention of vaginal candidiasis among female adolescent in the Adenta Municipality. Methods: A cross-sectional design and a multi-stage sampling technique was used to obtain a sample of 403 female adolescents within the Adenta Municipality using a structured questionnaire. The data collected from respondents were collected and entered into Epi Data Entry Client v4.0.2.4.9 and was exported into Stata 14.0 for analysis. All numerical data was analyzed using descriptive statistics. Chi-square, p-values were used to establish the associations between variables. Logistic regression of less than 0.05 were considered statistically significant at 95% confidence interval. Results were presented in tables and graphs. Result: The study revealed that the overall knowledge of respondents was good (54.7%). Majority (57.7%) of the respondents knew poor hygiene to be the major cause of vaginal candidiasis and it can easily be transmitted through sexual intercourse (67.8%). About 97% of the respondents most agreed that sugar intake was a major risk factor of vaginal candidiasis with (39.9%) of them knowing infertility as a major effect of vaginal candidiasis if not treated. Friends (47.5%) and school (41.1%) were seen to be the major source of information regarding vaginal candidiasis. The attitude towards the prevention of candidiasis among female adolescents was good (58.9%). Though, more than 50% of the respondents agreed that candidiasis infection was dangerous, majority (82.7%) of them were unsure of symptoms and therefore (87.6%) agreed that people infected with candidiasis must seek for treatment from the hospital. Having a good knowledge on vaginal candidiasis [AOR=2.56 (95% Cl: 1.57– 4.15), p<0.001] and a good attitude towards it prevention [AOR=1.83 (95% Cl: 1.12–2.99), p<0.015] were positively associated with the effects of vaginal candidiasis. These participants were 3 and 2 times respectively more likely to have good attitudes towards the effects of vaginal candidiasis respectively. Also, the participants who were in a relationship with the opposite sex was statistically significant such that those who were in a relationship were 3 times more likely to be knowledgeable about candidiasis [AOR=2.96 (95% Cl: 1.14 – 7.84), p<0.025] as compared with those who were not in a relationship. In conclusion, female adolescents in the Adenta Municipality had good knowledge on the causes and effects of vaginal candidiasis. Those aged 10-15 years exhibited poor knowledge and attitudes regarding the causes, effects and prevention of vaginal candidiasis. Programs aimed at increasing the knowledge, attitudes of female adolescents on vaginal candidiasis should be implemented and more attention should be given to the adolescents between the ages of 10 and 15 years. The responses given by respondents was seen to be influenced by the socio-demographic characteristics such as age, level of education, religion and ethnic group.

Case Report: Micafungin for treating Candida glabrata urinary infection: a clinical case in a premature neonate

Urinary tract infections (UTIs) associated with indwelling urinary catheterization (IUC) in premature newborns (PNBs) pose a significant challenge in neonatal intensive care units (NICUs) due to the vulnerability of this population to infections and the necessity of invasive procedures. While bacterial UTIs have historically been predominant, there is a rising incidence of fungal pathogens, particularly non-albicans Candida strains like Candida glabrata and Candida tropicalis, attributed to broad-spectrum antibiotic use. Diagnosis of fungal UTIs in a PNB relies on culturing Candida spp. from properly collected urine samples, particularly critical in very low birth weight (VLBW) PNBs because of the risk of invasive candidiasis and associated complications. We present a case of an extremely premature newborn (EPNB) successfully treated for a UTI caused by C. glabrata with micafungin. Our case exhibits micafungin as a potentially safe and effective alternative for treating C. glabrata UTIs in neonates.

Temporal trends in antibiotic prescribing and serious and nonserious infections in children presenting to general practice: a registry-based longitudinal cohort study of 162 507 individuals.

It is crucial to understand the trends in paediatric antibiotic prescribing and serious and nonserious infections to improve antibiotic prescribing practices for children in ambulatory care. Assessing trends in paediatric antibiotic prescribing and infection incidence in general practice from 2002 to 2022. In this retrospective cohort study using INTEGO network data from 162 507 patients in Flanders (Belgium), we calculated antibiotic prescribing rates and proportions alongside incidence rates of serious and nonserious infections, stratified by age (0-1, 2-6, 7-12 years) and municipality. We performed autoregressive moving average time-series analyses and seasonality analyses. From 2002 to 2022, antibiotic prescribing rate decreased significantly: 584/1000 person-years (PY) (95% CI 571-597) to 484/1000PY (95% CI 478-491); so did antibiotic overall prescribing proportion: 46.3% (95% CI 45.1-47.6) to 23.3% (95% CI 22.9-23.7) (59.3% amoxicillin and 17.8% broad spectrum). Prescribing proportions dropped significantly for nonserious (45.6% to 20.9%) and increased for serious infections (64.1% to 69.8%). Proportions significantly dropped for acute suppurative otitis media (74.7% to 64.1%), upper respiratory tract infections (44.9% to 16.6%), bronchitis/bronchiolitis (73.6% to 44.1%) and acute tonsillopharyngitis (59.5% to 21.7%), while significantly increasing for pneumonia (65.2% to 80.2%). Nonserious and serious infection incidence rates increased from 785/1000PY and 34.2/1000PY to 1223/1000PY and 64.1/1000PY, respectively. Blood and CRP testing proportions increased significantly. Antibiotic prescribing in general practice for children declined from 2002 to 2022. Further targeted antibiotic stewardship initiatives are needed to reduce the use of broad-spectrum antibiotics and antibiotic prescribing for conditions such as otitis media and bronchitis/bronchiolitis.

Microbiological diagnosis of pleural infections: a comparative evaluation of a novel syndromic real-time PCR panel.

Current microbial diagnostics for pleural infections are insufficient. Studies using 16S targeted next-generation sequencing report that only 10%-16% of bacteria present are cultured and that 50%-78% of pleural fluids containing relevant microbial DNA remain culture negative. As a rapid diagnostic alternative suitable for clinical laboratories, we wanted to explore a PCR-based approach. Based on the identification of key pathogens, we developed a syndromic PCR panel for community-acquired pleural infections (CAPIs). This was a pragmatic PCR panel, meaning that it was not designed for detecting all possibly involved bacterial species but for confirming the diagnosis of CAPI, and for detecting bacteria that might influence choice of antimicrobial treatment. We evaluated the PCR panel on 109 confirmed CAPIs previously characterized using culture and 16S targeted next-generation sequencing. The PCR secured the diagnosis of CAPI in 107/109 (98.2%) and detected all present pathogens in 69/109 (63.3%). Culture secured the diagnosis in 54/109 (49.5%) and detected all pathogens in 31/109 (28.4%). Corresponding results for 16S targeted next-generation sequencing were 109/109 (100%) and 98/109 (89.9%). For bacterial species included in the PCR panel, PCR had a sensitivity of 99.5% (184/185), culture of 21.6% (40/185), and 16S targeted next-generation sequencing of 92.4% (171/185). None of the bacterial species present not covered by the PCR panel were judged to impact antimicrobial therapy. A syndromic PCR panel represents a rapid and sensitive alternative to current diagnostic approaches for the microbiological diagnosis of CAPI.IMPORTANCEPleural empyema is a severe infection with high mortality and increasing incidence. Long hospital admissions and long courses of antimicrobial treatment drive healthcare and ecological costs. Current methods for microbiological diagnostics of pleural infections are inadequate. Recent studies using 16S targeted next-generation sequencing as a reference standard find culture to recover only 10%-16% of bacteria present and that 50%-78% of samples containing relevant bacterial DNA remain culture negative. To confirm the diagnosis of pleural infection and define optimal antimicrobial therapy while limiting unnecessary use of broad-spectrum antibiotics, there is a need for rapid and sensitive diagnostic approaches. PCR is a rapid method well suited for clinical laboratories. In this paper we show that a novel syndromic PCR panel can secure the diagnosis of pleural infection and detect all bacteria relevant for choice of antimicrobial treatment with a high sensitivity.

Significance of colonization by antibiotic-resistant organisms prior to congenital heart disease surgery in children from low- to middle-income countries sent by non-governmental organizations to Switzerland.

Children with congenital heart disease (CHD) from low- to middle-income countries (LMIC) are suspected to have a high prevalence of antibiotic-resistant microorganisms (ARMOs) carriage, but data are currently lacking. Carriage of ARMOs could impact the post-operative course in pediatric intensive care unit (PICU). The aim of the study was to assess the prevalence of ARMOs carriage in children with CHD from LMIC and its impact on post-operative outcomes. This was a retrospective monocentric study from 01/2019 to 12/2022. Included patients were children (0-18 years) from a LMIC admitted after CHD surgery and with AMRO screening performed the week before. Infections and post-operative evolution were compared based on ARMOs carriage status. Among 224 surgeries (median age 38.5 months (IQR 22-85.5)), ARMOs carriage was evidenced in 95 cases (42.4%). Main organisms isolated were Extended Spectrum Beta-Lactamase (ESBL) producing E. coli (75/224) 33.5%)) and ESBL-K. pneumoniae (30/224) 13.4%)). Median mechanical ventilation duration was 1 day (IQR 0-1), PICU stay 3 days (IQR 2-4) and hospital stay 6.5 days (IQR 5-10). A total of 17 infectious episodes occurred in 15 patients, mostly consisting in hospital-acquired pneumonia (HAP) (12/17). Only two infections were caused by a colonizing ARMO. Occurrence of infections and patients' outcome were similar between ARMO carriers and non-carriers. Higher use of carbapenems (6 (6.3%) vs 1 (0.8%), p = 0.04) and a trend to a higher use of vancomycin (14 (13.7%) vs 9 (6.9%), p = 0.04) in case of ARMOs carriage. Applying current guidelines, negative swab screening could have led to sparing most of empirical vancomycin therapy (11/12) for HAP based on current guidelines. Prevalence of AMROs carriage is high in children from LMIC and has a limited impact on patients' outcome. However, ARMOs carriage leads to higher consumption of antibiotics. Screening may help saving use of broad-spectrum antibiotic in non-carrier patients.

Wide use of broad-spectrum antibiotics in very low birth weight infants with spontaneous focal intestinal perforation-is it really justified?

Very low birth weight (VLBW) infants are at a risk of spontaneous focal intestinal perforation (FIP). Treatment includes supportive care, antibiotics, and drainage with/without surgery. Broad-spectrum antibiotic agents like carbapenems are applied frequently, although their use is not well-supported by the limited evidence of causal pathogens. We hypothesize that the use of carbapenems may not be necessary in VLBW infants with FIP. Our primary objective was to evaluate the antimicrobial use in VLBW infants with FIP in a cohort of the German Neonatal Network (GNN). The secondary objective was to characterize a subset in detail as a benchmark for future targets of stewardship. Data on VLBW infants with FIP was collected prospectively within the GNN, a collaboration of 68 neonatal intensive care units (NICU). With regards to the primary objective, patient characteristics and antimicrobial treatment were extracted from the predefined GNN database. To address our secondary objective, an additional on-site assessment of laboratory and microbiological culture results were performed. In the GNN cohort, 613/21,646 enrolled infants (2.8%) developed FIP requiring surgery. They were frequently treated with carbapenems (500/613 (81.6%)) and vancomycin (497/613 (81.1%)). In a subset of 124 VLBW infants, 77 (72.6%) had proof of gram-positive bacteria in the abdominal cavity, coagulase-negative staphylococci (CoNS) predominantly. Despite the low prevalence of gram-negative bacteria (n = 6 (4.8%)), the combination of meropenem and vancomycin was prescribed most frequently (n = 96 (78.0%)). The use of carbapenems as broad-spectrum antimicrobials agents might not be justified in most VLBW infants with FIP. Knowledge on the development of the neonatal gut microbiota, local resistance patterns and individual microbiological findings should be taken into consideration when implementing antimicrobial stewardship programs (ASPs).

An agent-based model on antimicrobial de-escalation in intensive care units: Implications on clinical trial design.

Antimicrobial de-escalation refers to reducing the spectrum of antibiotics used in treating bacterial infections. This strategy is widely recommended in many antimicrobial stewardship programs and is believed to reduce patients' exposure to broad-spectrum antibiotics and prevent resistance. However, the ecological benefits of de-escalation have not been universally observed in clinical studies. This paper conducts computer simulations to assess the ecological effects of de-escalation on the resistance prevalence of Pseudomonas aeruginosa-a frequent pathogen causing nosocomial infections. Synthetic data produced by the models are then used to estimate the sample size and study period needed to observe the predicted effects in clinical trials. Our results show that de-escalation can reduce colonization and infections caused by bacterial strains resistant to the empiric antibiotic, limit the use of broad-spectrum antibiotics, and avoid inappropriate empiric therapies. Further, we show that de-escalation could reduce the overall super-infection incidence, and this benefit becomes more evident under good compliance with hand hygiene protocols among health care workers. Finally, we find that any clinical study aiming to observe the essential effects of de-escalation should involve at least ten arms and last for four years-a size never attained in prior studies. This study explains the controversial findings of de-escalation in previous clinical studies and illustrates how mathematical models can inform outcome expectations and guide the design of clinical studies.

Towards personalised anti-microbial and immune approaches to infections in acute care. Can real-time genomic-informed diagnosis of pathogens, and immune-focused therapies improve outcomes for patients? An observational, experimental study protocol.

Infection causes a vast burden of disease, with significant mortality, morbidity and costs to health-care systems. However, identifying the pathogen causative infection can be challenging, resulting in high use of broad-spectrum antibiotics, much of which may be inappropriate. Novel metagenomic methods have potential to rapidly identify pathogens, however their clinical utility for many infections is currently unclear. Outcome from infection is also impacted by the effectiveness of immune responses, which can be impaired by age, co-morbidity and the infection itself. The aims of this study are twofold: To compare diversity of organisms identified and time-to-result using metagenomic methods versus traditional culture -based techniques, to explore the potential clinical role of metagenomic approaches to pathogen identification in a range of infections.To characterise the ex vivo function of immune cells from patients with acute infection, exploring host and pathogen-specific factors which may affect immune function and overall outcomes. This is a prospective observational study of patients with acute infection. Patients with symptoms suggestive of an acute infection will be recruited, and blood and bodily fluid relevant to the site of infection collected (for example, sputum and naso-oropharyngeal swabs for respiratory tract infections, or urine for a suspected urinary tract infection). Metagenomic analysis of samples will be compared to traditional microbiology, alongside the antimicrobials received. Blood and respiratory samples such as bronchoalveolar lavage will be used to isolate immune cells and interrogate immune cell function. Where possible, similar samples will be collected from matched participants without a suspected infection to determine the impact of infection on both microbiome and immune cell function.

Identifying General Practitioners' Antibiotic Prescribing Profiles Based on National Health Reimbursement Data.

Antibiotic selection pressure in human medicine is a significant driver of antibiotic resistance in humans. The primary aspect of antibiotic consumption is associated with general practitioner (GP) prescriptions. We aimed to identify prescriber profiles for targeted antimicrobial stewardship programs using novel indicators. A cross-sectional study was conducted in 2018 investigating GPs' antibiotic prescriptions in a French department, utilizing the reimbursement database of the national health service. Three antibiotic prescribing indicators were used. Specific targets were established for each indicator to identify the antibiotic prescribers most likely contributing to the emergence of resistance. Over 2018, we had 2,908,977 visits to 784 GPs, leading to 431,549 antibiotic prescriptions. Variations between GPs were shown by the 3 indicators. The median antibiotic prescription rate per visit was 13.6% (interquartile range [IQR], 9.8%-17.7%). Median ratios of the prescriptions of low-impact antibiotics to the prescriptions of high-impact antibiotics and of amoxicillin prescriptions to amoxicillin-clavulanic acid prescriptions were 2.5 (IQR, 1.7-3.7) and 2.94 (IQR, 1.7-5), respectively. We found 163 (21%) high prescribers of antibiotics with 3 distinct patterns: The first group overuses broad-spectrum antibiotics but without an overprescription rate per visit, the second group displays an overprescription rate but no excessive use of broad-spectrum antibiotics, and the third group shows both an overprescription rate and excessive use of broad-spectrum antibiotics. Prescription-based indicators enable the identification of distinct profiles of antibiotic prescribers. This identification may allow for targeted implementation of stewardship programs focused on the specific prescribing patterns of each profile.

Utilization of broad- versus narrow-spectrum antibiotics for the treatment of outpatient community-acquired pneumonia among adults in the United States.

To characterize antibiotic utilization for outpatient community-acquired pneumonia (CAP) in the United States. We conducted a cohort study among adults 18-64 years diagnosed with outpatient CAP and a same-day guideline-recommended oral antibiotic fill in the MarketScan® Commercial Database (2008-2019). We excluded patients coded for chronic lung disease or immunosuppressive disease; recent hospitalization or frequent healthcare exposure (e.g., home wound care, patients with cancer); recent antibiotics; or recent infection. We characterized utilization of broad-spectrum antibiotics (respiratory fluoroquinolone, β-lactam + macrolide, β-lactam + doxycycline) versus narrow-spectrum antibiotics (macrolide, doxycycline) overall and by patient- and provider-level characteristics. Per 2007 IDSA/ATS guidelines, we stratified analyses by otherwise healthy patients and patients with comorbidities (coded for diabetes; chronic heart, liver, or renal disease; etc.). Among 263 914 otherwise healthy CAP patients, 35% received broad-spectrum antibiotics (not recommended); among 37 161 CAP patients with comorbidities, 44% received broad-spectrum antibiotics (recommended). Ten-day antibiotic treatment durations were the most common for all antibiotic classes except macrolides. From 2008 to 2019, broad-spectrum antibiotic use substantially decreased from 45% to 19% in otherwise healthy patients (average annual percentage change [AAPC], -7.5% [95% CI -9.2%, -5.9%]), and from 55% to 29% in patients with comorbidities (AAPC, -5.8% [95% CI -8.8%, -2.6%]). In subgroup analyses, broad-spectrum antibiotic use varied by age, geographic region, provider specialty, and provider location. Real-world use of broad-spectrum antibiotics for outpatient CAP declined over time but remained common, irrespective of comorbidity status. Prolonged duration of therapy was common. Antimicrobial stewardship is needed to aid selection according to comorbidity status and to promote shorter courses.

Invasive candidiasis.

Invasive candidiasis is an important fungal disease caused by Candida albicans and, increasingly, non-albicans Candida pathogens. Invasive Candida infections originate most frequently from endogenous human reservoirs and are triggered by impaired host defences. Signs and symptoms of invasive candidiasis are non-specific; candidaemia is the most diagnosed manifestation, with disseminated candidiasis affecting single or multiple organs. Diagnosis poses many challenges, and conventional culture techniques are frequently supplemented by non-culture-based assays. The attributable mortality from candidaemia and disseminated infections is ~30%. Fluconazole resistance is a concern for Nakaseomyces glabratus, Candida parapsilosis, and Candida auris and less so in Candida tropicalis infection; acquired echinocandin resistance remains uncommon. The epidemiology of invasive candidiasis varies in different geographical areas and within various patient populations. Risk factors include intensive care unit stay, central venous catheter use, broad-spectrum antibiotics use, abdominal surgery and immune suppression. Early antifungal treatment and central venous catheter removal form the cornerstones to decrease mortality. The landscape of novel therapeutics is growing; however, the application of new drugs requires careful selection of eligible patients as the spectrum of activity is limited to a few fungal species. Unanswered questions and knowledge gaps define future research priorities and a personalized approach to diagnosis and treatment of invasive candidiasis is of paramount importance.

Eleven years impact of a stepwise educational program on healthcare associated infections and antibiotics consumption in an intensive care unit of a tertiary hospital in Brazil

BackgroundHospital acquired infections (HAI) and liberal use of broad-spectrum antibiotics are common in intensive care unit(ICU)s of low-middle income countries. We investigated the long-term association of a stepwise multifaceted educational program with the incidence of HAIs and antibiotics use in a Brazilian ICU. We also evaluated the program's cost impact. MethodsWe retrieved data from a prospective daily collected database of a twelve bedrooms ICU, all admitted patients within a period of eleven years were enrolled. FindingsFrom 03/15/2007 to 09/11/2019, we admitted 3059 patients where 2406 (79%) survived the ICU stay. Median age was 51 years-old, and median SAPS3 was 53. The initial density of catheter related blood infection (4.3 events / 1000 patients-day), urinary tract infection (9.2 event / 1000 patients-day) and ventilator associated pneumonia (54.9 events / 1000 patients-day) felt during the observed period to (0.35 events / 1000 patients-day), (0 events / 1000 patients-day), and (1.5 events / 1000 patients-day) respectively. The days of antibiotic therapy also decreased from 797.9 days of therapy / 1000 patients day to 292.3 days of therapy / 1000 patients day. The total cost per patient also decreased. The adjusted mortality rate was steady during the studied period from 23.2% to 22.9%. InterpretationA stepwise multifaceted educational program is an effective way to reduce hospital-associated infections, improve the rational use of antibiotics, and reduce costs. This impact occurred in a long term, and is probably consistent.

Candida auris Infection, a Rapidly Emerging Threat in the Neonatal Intensive Care Units: A Systematic Review.

(1) Background: In recent years, a global epidemiological shift in candidemia has been observed, marked by the emergence of resistant non-albicans Candida species. Candida auris, in particular, has become a significant global concern, causing infections in both pediatric and adult populations within healthcare settings. Despite its widespread impact, there is a limited understanding of the clinical course and transmission dynamics of neonatal systemic Candida auris infections, hindering effective prevention and management. This study focused on the epidemiologic data, the clinical presentation, risk factors, and outcome of C. auris infection in neonatal population. (2) Methods: A systematic review of the literature using PubMed and Scopus databases until December 2023 was conducted. (3) Results: A total of 24 relevant studies were identified, encompassing 476 documented cases of Candida auris infection in neonates. Prematurity emerged as a primary risk factor, alongside total parenteral nutrition, central line insertion, mechanical ventilation, and prior broad-spectrum antibiotic use. The mortality rate reached approximately 42%, with therapeutic details sparingly reported in 12% of cases. Treatment strategies varied, with amphotericin B predominantly used as monotherapy, while combination antifungal agents were used in 44% of cases. Notably, 97.4% of cases exhibited fluconazole resistance, and 67.1% showed resistance to amphotericin B. Limited data were available on resistance to other antifungal agents. (4) Conclusions: Despite the rarity of neonatal Candida auris infections, their global occurrence necessitates comprehensive preparedness in patient care. A deeper understanding of Candida auris pathogenesis is crucial for developing effective strategies to control and prevent neonatal infections caused by this pathogen.

Compliance with guideline recommendations in the management of patients with hospitalized community-acquired pneumonia.

Compliance with guidelines in the empirical treatment for community-acquired pneumonia (CAP) is very important to increase treatment success and reduce mortality. This study aimed to determine compliance with guideline recommendations for CAP and define the role of the clinical pharmacist (CP). Patients diagnosed with CAP were evaluated retrospectively between January 2018 and January 2020 and prospectively between February 2020 and February 2021. Compliance with guidelines was evaluated according to the local, national (Turkish Thoracic Society), and international (American Thoracic Society and Infectious Disease Society of America, European Society of Clinical Microbiology and Infectious Diseases) guidelines. A total of 751 patients (423 in the retrospective and 328 in the prospective period) were included. It was determined that the 30-day mortality and length of stay were higher in patients who were not treated according to the guidelines. The compliance for empirical treatments was 16.3%-59.1% and 7.8%-30.1% in retrospective and prospective periods, respectively. During the prospective period, a total of 603 recommendations were made by CP, and 578 (95.9%) were accepted and implemented. In the prospective period, treatment duration was shortened, inappropriate fluoroquinolone use was decreased, the switch to oral treatment was increased, and the number of potential drug-drug interactions was decreased (p < 0.001). Compliance with guidelines is essential to be improved to reduce mortality, shorten the length of stay, determine the appropriate antimicrobial duration, and reduce the use of fluoroquinolones and broad-spectrum antibiotics unless necessary. CP intervention contributes to the rational selection of antimicrobials, limiting drug-drug interactions, avoiding toxicities, and compliance with guidelines.

Antibiotic consumption in French nursing homes between 2018 and 2022: A multicenter survey.

Monitoring antibiotic consumption is a key component to steer antimicrobial stewardship programs, including in nursing homes. We analyzed changes in antibiotic consumption in French nursing homes during 5 years, including the COVID-19 pandemic, to identify potential priorities for improvement. A multicenter survey was conducted between 2018 and 2022. The study was conducted across 220 French nursing homes with on-site pharmacies. Antibiotic consumption data were collected from pharmacy records and are expressed as defined daily doses per 1,000 resident days. Antibiotic indicators promoted by health authorities were calculated from quantitative data to evaluate the quality of prescribing. Antibiotic consumption significantly decreased between 2018 and 2022, particularly during the coronavirus disease 2019 (COVID-19) pandemic, despite a slight increase in 2022. During the study period, the most used antibiotic classes were penicillins (61.9% in 2022) followed by cephalosporins (10.5%), macrolides-lincosamides-streptogramins (7.3%) then fluoroquinolones (7.0%). Amoxicillin-clavulanic acid was the most consumed antibiotic; amoxicillin and ceftriaxone ranked second and third. Azithromycin consumption increased from 2020, as did the indicator regarding broad-spectrum antibiotics. The decreasing trend in antibiotic use and control of fluoroquinolone use over the study period suggest compliance with antibiotic use guidelines. However, changes in the use of broad-spectrum antibiotics and the substantial use of amoxicillin-clavulanic acid, although it is rarely a first-line antibiotic, highlight the need for antimicrobial stewardship activities and the usefulness of antibiotic consumption surveillance to identify priorities.

A Prospective Quasi-Experimental Study of Multifaceted Interventions Including Computerized Drug Utilization Evaluation to Improve an Antibiotic Stewardship Program.

This study aimed to determine and evaluate interventions that improve an antibiotic stewardship program (ASP) in reduction of the amount of antibiotic use and errors in drug utilization evaluation (DUE) form completion. A prospective quasi-experimental study was conducted to evaluate the effectiveness of the multifaceted interventions (preauthorization with computerized DUE, self-supervised checklists, and short active reminders of the antibiotic guidelines recommendations) incorporating an ASP among hospitalized internal medicine patients in a Thai tertiary care center. The preintervention period was from January to December 2018, and the postintervention period was from February 2019 to January 2020. A total of 9188 and 9787 patient data were analyzed during the preintervention and postintervention periods, respectively. The overall median antibiotic use (defined daily dose/1000 bed-days) was significantly decreased in the postintervention period compared with the preintervention period (867.68 versus 732.33; P < 0.001). The reduction in antibiotic use was predominantly observed among broad-spectrum antibiotics, including cefoperazone/sulbactam (15.35 versus 9.75; P = 0.04), cefepime (13.09 versus 6.37; P = 0.003), ciprofloxacin (32.99 versus 17.83; P < 0.001), piperacillin/tazobactam (99.23 versus 91.93; P = 0.03), meropenem (2.01 versus 0.99; P < 0.001), imipenem/cilastatin (9.53 versus 4.59; P = 0.04), and colistin (74.70 versus 22.34; P < 0.0001). The overall rate of errors in DUE form completion was significantly decreased after the intervention (40% versus 28%; P < 0.001). The incidence of carbapenem-resistant Enterobacteriaceae infections/colonization was significantly lower in the postintervention period (0.27 versus 0.12/1000 bed-days; P = 0.02). The study multifaceted interventions incorporating ASP were associated with significant reduction in the amount of broad-spectrum antibiotic use, DUE form completion errors, and incidence of carbapenem-resistant Enterobacteriaceae infection/colonization.

Risk factors for short-term prognosis of end-stage liver disease complicated by invasive pulmonary aspergillosis.

Patients with end-stage liver disease (ESLD) are susceptible to invasive pulmonary aspergillosis (IPA). This study aimed to investigate the risk factors affecting the occurrence and short-term prognosis of ESLD complicated by IPA. This retrospective case-control study included 110 patients with ESLD. Of them, 27 ESLD-IPA received antifungal therapy with amphotericin B (AmB); 27 AmB-free-treated ESLD-IPA patients were enrolled through 1:1 propensity score matching. Fifty-six ESLD patients with other comorbid pulmonary infections were enrolled as controls. The basic features of groups were compared, while the possible risk factors affecting the occurrence and short-term outcomes of IPA were analyzed. Data analysis revealed invasive procedures, glucocorticoid exposure, and broad-spectrum antibiotic use were independent risk factors for IPA. The 54 patients with ESLD-IPA exhibited an overall treatment effectiveness and 28-d mortality rate of 50.00% and 20.37%, respectively, in whom patients treated with AmB-containing showed higher treatment efficacy than patients treated with AmB-free antifungal regimens (66.7% vs. 33.3%, respectively, χ2 = 6.000, P = 0.014). Multivariate logistic regression analysis revealed that the treatment regimen was the only predictor affecting patient outcomes, with AmB-containing regimens were 4.893 times more effective than AmB-free regimens (95% CI, 1.367-17.515; P = 0.015). The only independent predictors affecting the 28-d mortality rate were neutrophil-to-lymphocyte ratio and IPA diagnosis (OR = 1.140 and 10.037, P = 0.046 and 0.025, respectively). Glucocorticoid exposure, invasive procedures, and broad-spectrum antibiotic exposure increased the risk of IPA in ESLD patients. AmB alone or combined with other antifungals may serve as an economical, safe, and effective treatment option for ESLD-IPA.

Rationality of antibiotic use in COVID-19 patients in the ICU of Dr. Hasan Sadikin General Hospital, Bandung; a cohort study

Background and Objectives: Nearly three-quarters of the patients with COVID-19 received antibiotic therapy despite the bacterial coinfection being only less than 10% in many studies and ranging from 8-22% in ICU patients. The use of broad-spectrum antibiotics in COVID-19 patients has not been proven effective. Overuse of antibiotics may be associated with side effects and antibiotic resistance. The purpose of this study was to determine the antibiotic rationality in COVID-19 patients in the ICU of Dr. Hasan Sadikin Hospital, Bandung, Indonesia.&#x0D; Methodology: This descriptive, retrospective cohort study was carried out by analyzing medical records of COVID-19 patients admitted in the ICU of Dr. Hasan Sadikin Hospital from January-June 2021.&#x0D; Results: There were 138 patients who met the inclusion criteria. A total of 126 (91.3%) patients received antibiotics. A total of 12 (8.7%) severe/critical patients did not receive antibiotics and 79 (62.70%) received inappropriate antibiotic duration. Inappropriate regimen was found in 59 patients (74.68%) with COVID-19 without HAP/VAP and 15 patients (31.92%) with HAP/VAP. The primary issue identified was the inappropriate regimen of antibiotics, Gyssens category 4a.&#x0D; Conclusion: This study concludes that 23.02% patients used rational empirical antibiotics and 45.98% used rational definitive antibiotics in COVID-19 patients in the ICU at RSUP Dr. Hasan Sadikin Bandung during January-June 2021.&#x0D; Abbreviations: ACE- Angiotensin Converting Enzyme; ICU- Intensive Care Unit; HAI- Hospital-Associated Infections; HAP- Hospital-Acquired Pneumonia; IDSA- Infectious Diseases Society of America VAP- Ventilator-Associated Pneumonia&#x0D; Key words: Antibiotics; Antimicrobial Resistance; COVID-19; Intensive Care Units; Prescribing Pattern&#x0D; Citation: Indriasari, Oktaliansah E, Munazat RI.

Long-Term Effects of a Stepwise, Multimodal, Non-Restrictive Antimicrobial Stewardship Programme for Reducing Broad-Spectrum Antibiotic Use in the ICU.

Information on the long-term effects of non-restrictive antimicrobial stewardship (AMS) strategies is scarce. We assessed the effect of a stepwise, multimodal, non-restrictive AMS programme on broad-spectrum antibiotic use in the intensive care unit (ICU) over an 8-year period. Components of the AMS were progressively implemented. Appropriateness of antibiotic prescribing was also assessed by monthly point-prevalence surveys from 2013 onwards. A Poisson regression model was fitted to evaluate trends in the reduction of antibiotic use and in the appropriateness of their prescription. From 2011 to 2019, a total of 12,466 patients were admitted to the ICU. Antibiotic use fell from 185.4 to 141.9 DDD per 100 PD [absolute difference, -43.5 (23%), 95% CI -100.73 to 13.73; p = 0.13] and broad-spectrum antibiotic fell from 41.2 to 36.5 [absolute difference, -4.7 (11%), 95% CI -19.58 to 10.18; p = 0.5]. Appropriateness of antibiotic prescribing rose by 11% per year [IRR: 0.89, 95% CI 0.80 to 1.00; p = 0.048], while broad-spectrum antibiotic use showed a dual trend, rising by 22% until 2015 and then falling by 10% per year since 2016 [IRR: 0.90, 95% CI 0.81 to 0.99; p = 0.03]. This stepwise, multimodal, non-restrictive AMS achieved a sustained reduction in broad-spectrum antibiotic use in the ICU and significantly improved appropriateness of antibiotic prescribing.
