Use of antibiotics in the early COVID-19 pandemic in Poland, the Netherlands and Spain, from erraticism to (more) logic.

INTRODUCTION: In the Spring of 2020, the world was hit with unparalleled impact by the coronavirus pandemic. Antibiotics were widely used, even without good rationale. The aim of our study was to compare the use of antibiotics in patients with confirmed COVID-19 from three hospitals across Europe (Poland, the Netherlands and Spain) between two subsequent periods in the early days of the pandemic. METHOD: We analysed data (antibiotics used and variation in the use of antibiotics, patients, admission and disease-related characteristics) from 300 patients admitted in three hospitals (University Hospital in Cracow, University Medical Center in Utrecht and Vall d'Hebron University Hospital in Barcelona) with confirmed infection of SARS-CoV-2 during Q1 2020 and Q4 2020. RESULTS: There was ample variation in terms of patient mix and outcomes across the 3 hospitals. The majority of patients (225 out of 300) in all 3 hospitals received at least 1 antibiotic during the hospitalisation period. A minority of patients (68 out of 300) had their bacterial test results positive during their hospitalisation period. Throughout the 2 study periods, third-generation cephalosporins (ceftriaxone in 170 out of 300 patients) emerged as the most commonly used class of antibiotics. There was an apparent shift towards more rational utilisation of antibiotics, in all three hospitals. CONCLUSIONS: Our study shows that during the early stage of COVID-19 pandemic in 2020, antibiotics were frequently used in three European teaching hospitals despite the relatively low incidence of microbiologically confirmed bacterial infections. While in the early days of the COVID-19 pandemic antibiotic prescribing was full of trial and error, we could also confirm a learning curve over time.

The effect of information provision on consumers' risk perceptions of, support for a ban, and behavioral intention towards the preventive use of antibiotics in food animals.

BACKGROUND: Antibiotics have been widely used in feed and drinking water for food animals to prevent them from getting sick. Such preventive use of antibiotics has become a contributor to increasing antibiotic resistance and thus poses threats to human health. However, consumers have little knowledge about this practice and the associated health risks of increasing transmission of antibiotic residues and antibiotic resistant bacteria. This study aimed to examine the effect of information provision on consumers' risk perceptions, support for a ban, and behavioral intention regarding the preventive use of antibiotics in food animals. Especially, the study sought to test two competing hypotheses which were informed by two theoretical perspectives of fear appeal theory - the linear model and the plateau effect model. The former suggested that providing information on the health risks of both antibiotic residues and antibiotic resistant bacteria would have a stronger effect compared to providing information on only one of them, while the latter posited that providing information on both risks might not have additional influence, as the effect of information on either risk could reach the plateau. METHODS: An experimental study with four conditions was conducted where participants read different information on the health risks associated with the preventive use first and then answered questions regarding consumers' risk perceptions, support for a ban, and behavioral intention regarding the preventive use. Condition 1 was the control condition, where basic information about antibiotics, antibiotic resistance, and the preventive use was provided. Condition 2 and Condition 3 further added information on the health risk of antibiotic residues (Condition 2) and antibiotic resistant bacteria (Condition 3) due to the preventive use, respectively. Condition 4 provided all information contained in the first three conditions. RESULTS: The results showed that compared to participants in the control condition, participants in Conditions 2-4 reported higher risk perceptions, stronger support for a ban on the preventive use, and a higher intention to buy meat produced without the preventive use of antibiotics. However, there were no significant differences in these factors between Conditions 2-4, indicating that providing information on the health risk of either antibiotic residues, or antibiotic resistant bacteria, or both, has similar effect on these variables. That is, the hypothesis based on the plateau effect model was supported. CONCLUSIONS: The findings suggested that informing the public with the health risk of either antibiotic residues or antibiotic resistant bacteria associated with the preventive use is effective enough to reach plateau effect in increasing risk perceptions, support for a ban, and behavioral intention, which has important implications for policymakers and livestock industries to develop effective communication strategies to promote responsible antibiotic use in food animals.

Effect of prudent use of antimicrobials in the early phase of infection in pigs on the performance and meat quality of fattening pigs.

The presented study was a part of the ThermoEye project. The study examined the effect of prudent antibiotic treatment in response to illness on the fattening performance, slaughter traits, and meat quality of the pig fatteners. Pigs were divided into an experimental group - EXP and a control - CON. In both groups, the body temperature was monitored, and diseases were confirmed by a veterinarian. In the EXP group, metaphylaxis was used in each case of confirmed disease. The EXP fatteners had greater slaughter weight (by 4.7 kg) and meatiness (by 2.1 percentage points) compared to the CON pigs. The pH in pork was lower in EXP compared to CON pigs. The longissimus thoracis et lumborum of EXP pigs was characterised by a lower cooking loss (28.30 vs. 30.45%) and yellower colour compared to the CON group. Among the amino acids, only the content of histidine (by 5.2%; P < 0.01) and tyrosine (by 7.2%; P < 0.01) was significantly greater in the meat of the CON group compared to EXP, with no effect of sex noted. The content of SFA (by 14.6%; P < 0.05), UFA (by 15.6%; P < 0.05), MUFA (by 17.8%; P < 0.05), MCFA (by 14.1%; P < 0.05), and LCFA (by 15.6%; P < 0.05) was also greater in CON compared to EXP meat. In conclusion, automated monitoring of pig body temperature during the fattening period enables more precise, prudent treatment and effective animal health control while reducing costs due to disease losses and pharmacotherapy. It allows optimal production and affects meat quality.

Self-medication with antibiotics in Georgian population.

Background: Self-medication with antibiotics is a global phenomenon and a potential contributor to human pathogen resistance to antibiotics. It involves obtaining medication without a prescription, taking medicines based on the advice of friends and relatives, or previous treatment experience. Self-medication is common in both developed and developing countries; however, the prevalence of self-medication is higher in developing countries. The aim of this study was to determine the characteristics of antimicrobial self-medication in Georgia and its potential to influence the overall situation regarding antimicrobial consumption in the country. Methods: We conducted a cross-sectional study using a random sampling method and developed a self-administered questionnaire to collect the data. The survey was conducted via the Internet using the Google Forms platform. Results: The overall number of respondents was 742 adults living in Georgia. The results showed that 23.8% (n = 177) of adults had consumed antibiotics without a doctor's prescription, and 12.7% (n = 94) confirmed the use of antibiotics by their own decision to treat minor family members. The total prevalence of self-medication was 32.6%. The data analysis revealed a correlation between factor F1 ("personal experience") and gender (p = 0.042, F = 2.6), and between age and factor F2 ("lack of trust in medical practitioners") (p = 0.047, F = 2.691). The correlation was stronger among young adults (aged 18-24) and senior adults (aged 60+). The correlation between the level of education and factor F2 was stronger (p = 0.00; F1 = 7.9) than with factor F1 (p = 0.04; F = 2.2). Conclusion: Self-medication is prevalent in Georgia; pharmacies are the main sources of antimicrobials. No correlation was found between factor F2, pertaining to "lack of trust in medical practitioners" and gender, between age and factor F1, linked to "personal experience." The study uncovered a lack of knowledge about self-medication with antibiotics and emphasized the importance of public awareness campaigns and implementing effective interventions to regulate the sales of antibiotics without a doctor's prescription.

Impact of Irrational Use of Antibiotics Among Patients in the Intensive Care Unit on Clinical Outcomes in Sudan.

Background: Intensive Care Unit (ICU) is a specialized ward where critically ill patients are admitted to provide intensive health care Inappropriate antimicrobial therapy (AMT) and high mortality rates were documented in the ICU. The influence of irrational use of empiric antibiotics on clinical outcomes in ICU patients is not well studied in Sudan. Aim: This study aims to determine the rational use of antibiotics and its impact on clinical outcomes among ICU patients. Methods: Using data collection form, a retrospective longitudinal study was conducted among ICU patients at Omdurman Military Hospital, Khartoum State. Patients admitted from January 2019 to December 2019 were included in the study. Patients who stayed in ICU < 48 hr were excluded. Appropriateness of AMT is assessed using culture sensitivity test (CST) and the American Society of Infectious Diseases (IDSA) guideline. Results: Among 102 patients, 54.9% male, one-third of patients developed nosocomial infections, 80.4% received empiric therapy with broad-spectrum antibiotics. The CST is done in 19%, and 43% patients are prescribed inappropriate AMT. Inappropriate AMT is associated with recurrent infections 38.4% (p=0.028) and high mortality 33.8% (p=0.014). Overall mortality rate 63.7% ICU patients. Elevated mortality in nosocomial 57.8%, decreased with inappropriate AMT in 21.6% patients. Significantly higher mortality rates 90.7% among uncontrolled infections (p<0.001), 80.6% nosocomial infections (p=0.001), and 76.7% renal compromised (p=0.002). Conclusion: Empirical AMT reduces the frequency of nosocomial infections, which has an impact on mortality. Inappropriate AMT is significantly associated with uncontrolled infections and lower mortality. Implementing a restrictive infectious control system and effective stewardship programs in hospital ICU wards is recommended.

[Antibiotic resistance: a public health priority in which everyone has a role to play!] / L'antibiorésistance : une priorité de santé publique, où chacun a un rôle à jouer !

Preserving the effectiveness of our antibiotics against pathogenic bacteria is a major public health issue, which is why the World Health Organization has made the fight against antibiotic resistance one of its ten priorities. The fight against antibiotic resistance must be implemented at international, national and local levels. Nurses, in close contact with patients, have a fundamental role to play in both pillars of the strategy implemented in France: in the prevention and control of infections, of course, but also in the proper use of antibiotics.

Procalcitonin-Based Antibiotic Use for Neonatal Early-Onset Bacterial Infections: Pre- and Post-Intervention Clinical Study.

We previously reported the 95th percentile cutoff value of the serum procalcitonin (PCT) reference curve for diagnosing early-onset bacterial infection. We aimed to verify the effectivity of these novel diagnostic criteria by comparing antibiotic use and incidence of early-onset bacterial infection between pre- and post-introduction periods. We included newborns admitted to our neonatal intensive care unit who underwent blood tests within 72 h after birth between 2018 and 2022. The neonates were divided into the pre-intervention (admitted before the introduction, n = 737) or post-intervention (admitted after the introduction, n = 686) group. The days of antibiotics therapy (DOT) per 1000 patient days up to 6 days after birth, percentage of antibiotic use, and incidence of early-onset bacterial infection were compared between the groups. The post-intervention group had significantly lower DOT per 1000 patient days (82.0 days vs. 211.3 days, p < 0.01) and percentage of newborns receiving antibiotics compared with the pre-intervention group (79 (12%) vs. 280 (38%), respectively, p < 0.01). The incidence of early-onset bacterial infections did not differ between the groups (2% each, p = 0.99). In conclusion, our diagnostic criteria using the 95th percentile cutoff value of the serum PCT reference curve for early-onset bacterial infection were proven safe and effective, promoting appropriate use of antibiotics.

Antibiotic Resistance and Its Impact on Disease Management.

Antibiotic resistance has been a challenge to the medical fraternity and has had a massive impact on disease management. The overuse of antibiotics and careless prescription by doctors have been one of the primary reasons for the development of antibiotic resistance among the masses. This article draws attention to the significant reasons causing antibiotic resistance, such as overuse, antibiotic resistance genes, and extensive use of antibiotics in agriculture. It also brings forward the challenges posed by antibiotic resistance in the management of various diseases like tuberculosis, COVID-19, and vancomycin-resistant enterococci infections. The article includes a case study that depicts the threat posed by antibiotic resistance in tuberculosis treatment. This article also shows the effects of antibiotic resistance on COVID-19 patient care and treatment. It further includes methods that can be implemented on international levels as well as individual ground levels to curb antibiotic resistance. One of the methods has a recent finding in which proteins produced in the body are being modified and used in treatments to reduce the use of antibiotics, which ultimately serves the goal of curbing antibiotic resistance by reducing overuse.

The Use of Antibiotics and Antimicrobial Resistance in Veterinary Medicine, a Complex Phenomenon: A Narrative Review.

As warned by Sir Alexander Fleming in his Nobel Prize address: "the use of antimicrobials can, and will, lead to resistance". Antimicrobial resistance (AMR) has recently increased due to the overuse and misuse of antibiotics, and their use in animals (food-producing and companion) has also resulted in the selection and transmission of resistant bacteria. The epidemiology of resistance is complex, and factors other than the overall quantity of antibiotics consumed may influence it. Nowadays, AMR has a serious impact on society, both economically and in terms of healthcare. This narrative review aimed to provide a scenario of the state of the AMR phenomenon in veterinary medicine related to the use of antibiotics in different animal species; the impact that it can have on animals, as well as humans and the environment, was considered. Providing some particular instances, the authors tried to explain the vastness of the phenomenon of AMR in veterinary medicine due to many and diverse aspects that cannot always be controlled. The veterinarian is the main reference point here and has a high responsibility towards the human-animal-environment triad. Sharing such a burden with human medicine and cooperating together for the same purpose (fighting and containing AMR) represents an effective example of the application of the One Health approach.

Análisis espacial y temporal de la enfermedad neumocócica invasora por serotipos resistentes a eritromicina / Spatial and temporal analysis of invasive pneumococcal disease due to erythromycinresistant serotypes

Objetivos: Estudiar la distribución espacio-temporal de los casos de enfermedad neumocócica invasora (ENI) por serotipos resistentes a eritromicina y su relación con el consumo comunitario de macrólidos y la cobertura vacunal infantil. Métodos: Se seleccionaron los casos de ENI en mayores de 59 años residentes en la Comunidad de Madrid (CM) notificados en el periodo de 2007 a 2016. Las variables estudiadas fueron obtenidas de los sistemas de información vacunal y de Prestación Farmacéutica. Se utilizó el punto de corte (concentración mínima inhibitoria de eritromicina > 0,5 mg/L) de la clasificación de EUCAST para definir los serotipos resistentes a eritromicina. Mediante JointPoint se estimaron las tendencias de las incidencias de casos por serotipos resistentes a eritromicina incluidos en la vacuna trecevalente (STVCN13) y no incluidos (STnoVCN13). La asociación de esas incidencias con el consumo comunitario de macrólidos y la cobertura vacunal se hizo mediante modelos de Poisson. Para la detección de clústeres espacio-temporales se utilizó el estadístico Satscan. Resultados: Se identificaron 1.936 casos, de ellos, se detectó que 427 serotipos eran resistentes a la eritromicina. La incidencia de todos los casos por serotipos resistentes fue descendente (AAPC: -5,40%). La incidencia de casos por STVCN13 resistentes a la eritromicina fue descendente con un porcentaje anual del cambio (APC: -13,8) y estuvo asociada inversamente a la cobertura vacunal infantil (IRR 0,641), mientras que la de casos por STnoVCN13 resistentes a eritromicina fue ascendente (APC: 4,5) y no se asoció con la cobertura. Se detectó un clúster por STnoVCN13 y ninguno por STVCN13 tras la inclusión de la trecevalente en el calendario vacunal infantil. Conclusiones: El descenso de ENI por STVCN13 resistentes se asoció con el incremento de la cobertura vacunal infantil...(AU)

Objectives: To study the spatio-temporal distribution of cases of invasive pneumococcal disease (IPD) due to serotypes resistant to erythromycin and its relationship with community consumption of macrolides and childhood vaccination coverage. Methods: We selected IPD cases in adults over 59 years old, residents in the Community of Madrid (MC), notified in the period 2007-2016. The variables studied were obtained from the Vaccination Information Systems and the Pharmaceutical Service. The cut-off point (minimum inhibitory erythromycin concentration > 0.5 mg/L) of the EUCAST classification was used to define erythromycin resistant serotypes. We used JointPoint to estimate the incidence trends by erythromycin resistant serotypes included in the 13-valent vaccine (STPCV13) and not included in it (STnoPCV13). The association of these incidences with the community consumption of macrolides and vaccination coverage was made using Poisson models. Statistical scanning was used for the detection of temporal-spaces clusters of cases. Results: 1936 cases were identified, of which 427 erythromycin resistant serotypes were identified. The incidence of all cases due to resistant serotypes was decreasing (AAPC: -5,40%). During the period studied, the incidence of cases due to erythromycin resistant STPCV13 was decreasing with an annual percentage change (APC): -13.8 and was inversely associated with childhood vaccination coverage (IRR 0.641), while that of cases due to erythromycin resistant STnoPCV13 was ascending (APC): 4.5; and was not associated with coverage. 1 cluster was detected by STnoPCV13 and none by STPCV13 after the date of inclusion of the 13-valent in the childhood vaccination calendar. Conclusions: The decrease in IPD due to resistant STPCV13 was associated with an increase in childhood vaccination coverage...(AU)

Spatial and temporal analysis of invasive pneumococcal disease due to erythromycinresistant serotypes.

CONCLUSIONS: The decrease in IPD due to resistant STPCV13 was associated with an increase in childhood vaccination coverage. The presence of clusters due to STnoPCV13 after the date of inclusion of the 13-valent vaccine in the childhood vaccination calendar indicates serotypes replacement. The increase in cases of resistant STnoPCV13 could be related to the replacement of vaccine serotypes in nasopharyngeal colonization, facilitated by the consumption of macrolides still at high levels in MC.

Availability of Access, Watch, and Reserve groups of essential antibiotics: a cross-sectional survey.

Background: Lower-middle income countries face drastic challenges in Access to essential medicines. Data regarding Pakistan is scarce with no comprehensive study in this regard. The objectives of the study are to document and compare public and private sector availability of all essential antibiotics as well as to conduct a comparison among the AWaRe groups. Methods: The study analyzed 103 essential antibiotics comprising 51 Access, 29 Watch, 6 Reserve, and 17 anti-tuberculosis drugs from 15th August to 10th September 2020 in Lahore, Pakistan. It included on-spot physical availability and availability trend surveys. The survey sites included five public tertiary care hospitals with one as anchor and four randomly selected. Their hospital pharmacies and one randomly selected private retail pharmacy from the vicinity each hospital comprised the ten sampling sites. Percentage availability for each antibiotic was categorized as high (>80%), fairly high (50-80%), low (30-<50%), very low (<30->0%), and not available (0%). Results: The mean percentage on-spot availability was 23.76% ± 5.19 (14-25%) for public facilities and 59.20% ± 4.45 (54-66%) for private sector retail pharmacies. The overall percentage of available essential antibiotics varied significantly (p** < 0.001) in public and private sector sampling sites. Except for the Watch group, all other groups showed the mode of 0% availability. A significant difference (p**** < 0.00001) was seen in percentage availability by Access, Watch, Reserve, and anti-TB-all groups of essential antibiotics. The availability trend survey revealed a list of 18 medicines as 'as never been available', and five medicines were 'not available for 5 years or more than 5 years.' Fourteen medicines as 'never been heard.' Conclusion: Non-availability of essential medicines is a significant public health challenge at public-sector facilities in Pakistan. It was observed that a number of essential antibiotics were not available in both public and private sectors. A number of corrective strategies are required. This includes the engagement of stakeholder and government bodies. This can help to improve supply chain barriers.

Multiple factors affecting perioperative antibiotherapy in minimally invasive lung surgery: a retrospective case-control study.

Background: During the perioperative period, empiric antibiotic escalation therapy is not uncommon, leading to longer postoperative hospital stay and higher medical expenses. However, few systematic studies have investigated this issue. In this case-control study, we explored the factors affecting empiric antibiotic escalation therapy after minimally invasive lung surgery during hospitalization, with the aim to enhance recovery after surgery and rational use of antibiotics. Methods: The data of patients who underwent minimally invasive lung surgery at our center from January 2019 to December 2020 were collected from the hospital information system (HIS). A total of 1,360 cases were identified based on the inclusion and exclusion criteria. These patients were divided into 2 groups: group A (n=825), in which patients did not receive antibiotic escalation therapy after surgery; and group B (n=535), in which patients received empiric antibiotic escalation therapy after surgery. A logistic regression model was used to analyze the influencing factors of empiric antibiotherapy escalation during postoperative hospitalization. Results: Compared with group A, group B had significantly longer postoperative hospital stay (5.05±2.78 vs. 4.49±2.24 days, P<0.001) and slightly higher average total hospitalization costs (74,080.85±23,796.51 vs. 71,798.09±21,307.26 yuan, P=0.067). Multivariate analysis showed that the statistically significant factors included history of secondary lung surgery [odds ratio (OR): 3.267; 95% confidence interval (CI): 1.305-8.178; P=0.011], preoperative hemoglobin A1c (HbA1c) ≥6.5% (OR: 1.603; 95% CI: 1.143-2.249; P=0.006), postoperative fever of unknown origin [temperature (T) >38 ℃; OR: 2.494; 95% CI: 1.321-4.708; P=0.005], postoperative hypoalbuminemia (intravenous albumin administration for ≥2 days; OR: 14.125; 95% CI: 1.777-112.282; P=0.012). Conclusions: Multivariate analysis showed that history of secondary lung surgery, preoperative HbA1c ≥6.5%, postoperative fever of unknown origin (T >38 ℃), and postoperative hypoalbuminemia (<35 g/L and intravenous albumin administration ≥2 days) were the independent risk factors for empiric antibiotic escalation therapy after minimally invasive lung surgery. For preoperative risk factors, further cohort studies should be conducted to explore better intervention indicators or measures. For postoperative risk factors, perioperative dynamic monitoring of procalcitonin can guide the rational use of antibiotics, reduce the risk of drug resistance and hospitalization cost.

Self-Medication With Antibiotics: An Element Increasing Resistance.

Self-medication refers to the consumption of drugs such as antibiotics by individuals based on their own experience and knowledge, without consulting a doctor either for diagnosis or prescription. The inappropriate use of antibiotics is the primary source of antibiotic resistance (AR) development in microorganisms. As a result, some specific types of microorganisms that are naturally resistant to antibiotics have become considerably more common. Self-medication poses a danger to the advantages of antibiotics since it results in financial burdens on low and middle-income countries (LMICs), management failures, the evolution of antibiotic-resistant bacterial serotypes, and a higher risk of contamination of the general population by such tensions. Antibiotic misuse puts patients at risk for adverse drug reactions, false symptom relief, and the rise of drug-resistant microorganisms. It carries many health risks, chiefly in LMICs. These risks are linked to various factors, including a shortage of medical experts, low-level healthcare facilities, unregulated medication delivery, and negative public perceptions of doctors. The primary issue with self-medication is that majority of the population is uninformed of the harmful consequences of antibiotic resistance and how they might donate to it by self-diagnosing and self-treating with antibiotics. Antibiotic self-medication remains a common practice in society, and educational attainment significantly affects the frequency of this behavior. The article aims to educate the people by showing the development and plausible future to decrease antibiotic misuse. It also tells about the various challenges and prevention of this preceding problem.

Antibiotic Stewardship in Patients With Acute Bronchitis: A Case Report of Doxycycline-Induced Esophagitis.

Acute bronchitis is a self-limiting disease, characterized by mild constitutional symptoms and a cough lasting two to three weeks. The disease usually occurs secondary to viruses; therefore, only symptomatic and supportive care is advised for the patients. Despite the recommended guidelines, most patients are prescribed antibiotics. Here, we present a case of a 38-year-old female who presented to the hospital with a sudden onset of severe epigastric pain. The patient recently started a 10-day course of doxycycline for acute bronchitis. She was admitted, evaluated, and diagnosed with doxycycline-induced esophagitis, and managed accordingly. This report highlights how excessive use of antibiotics is leading to adverse effects, antibiotic resistance, increased health care costs, and invasive testing. It also emphasizes the importance of antibiotic stewardship.

Effect of glycyrrhizin administration followed by symptom-based antimicrobial selection therapy on antimicrobial use in clinical mastitis without systemic symptoms.

In bovine mastitis, antimicrobial treatment is often initiated before the causative organism is identified a problem in the prudent use of antimicrobials. In this study, we aimed to reduce the total amount of antimicrobials used in mastitis treatment by administering glycyrrhizin, an anti-inflammatory drug, instead of antimicrobials at the onset of clinical mastitis without systemic symptoms, followed by symptom-based antimicrobial selection therapy (ST), to examine the effect of this treatment strategy on treatment outcomes and antimicrobial use. Comparisons between cases that received antimicrobial treatment starting from the day of diagnosis (blanket antibiotic therapy [BT] group: 33 cases) and cases that received ST starting from the day after the diagnosis (ST group: 57 cases) revealed no difference in the cure rate, milk withholding period, or recurrence rate. However, the ST group had a significantly lower amount of antimicrobials than the BT group. Additionally, a single administration of glycyrrhizin before ST significantly relieved the udder symptoms and reduced the antimicrobial amount when compared with cases without glycyrrhizin administration. Thus, a single administration of glycyrrhizin followed by ST can reduce the total antimicrobial use.

Inappropriate use of antibiotics and its predictors in pediatric patients admitted at the Central Hospital of Nampula, Mozambique.

BACKGROUND: Antibiotics are synthetic or natural substances used to treat bacterial infectious diseases. When used incorrectly, they can be a factor in the development of antimicrobial resistance, increased treatment time, costs, and mortality. The present study aimed to assess the pattern of inappropriate use of antibiotics and their predictors in pediatric patients admitted to the Central Hospital in Nampula, Mozambique. METHODS: A cross-sectional, retrospective study with a quantitative approach was conducted between January and July 2019. The population consisted of children ages 0-10 years hospitalized in the pediatric ward I. Binary logistic regression was used to determine risk factors for the inappropriate use of antibiotics with 95% confidence interval. RESULTS: The prevalence of antibiotic use among pediatric patients was 97.5%. Of the 464 antibiotics prescribed, 39.9% were for patients suffering from gastroenteritis, 21.8% and 9.1% for those affected with pneumonia and malaria, respectively. Most antibiotics were for parenteral use (95.9%, 445/464). Many (36.5%) of the prescriptions had errors, primarily in the duration of treatment (74.0%) or dosage (24.4%). Binary logistic regression analysis revealed that patients prescribed ≥ 3 antibiotics (OR = 2.83, 95% CI 1.245-6.462, p-value = 0.013) or hospitalized for a short time (OR = 1.88, 95% CI 1.133-2.3140, p-value = 0.015) were more likely to experience inappropriate use of antibiotics. CONCLUSION: The study showed both a high prevalence of antibiotic use and a high error rate in prescriptions, especially among patients prescribed ≥ 3 antibiotics or hospitalized for a short time. These results are concerning, since inappropriate and excessive use of antibiotics is a major factor in the development of antibiotic-resistant microorganisms. Therefore, policies to reduce the inappropriate and excessive use of antibiotics are necessary.

Unraveling the Nature of Antibiotics: Is It a Cure or a New Hurdle to the Patient Treatment?

Antimicrobial resistance is an increasing problem worldwide that has been exacerbated by antibiotic misuse worldwide. Growing antibiotic resistance can be attributed to as well as leads to severe infections, complications, prolonged hospital admissions, and higher mortality. One of the most important goals of administering antimicrobials is to avoid establishing antibiotic resistance during therapy. This can be done by drastically lowering worldwide antimicrobial usage, both in present and future. While current management methods to legislate antimicrobials and educate the healthcare community on the challenges are beneficial, they do not solve the problem of attaining an overall reduction in antimicrobial usage in humans. Application of rapid microbiological diagnostics for identification and antimicrobial susceptibility testing, use of inflammation markers to guide initiation and duration of therapies, reduction of standard antibiotic course durations, individualization of antibiotic treatments, and dosing considering pharmacokinetics are all possible strategies to optimize antibiotic use in everyday clinical practice and reduce the risk of inducing bacterial resistance. Furthermore, to remove any impediments to proper prescribing, strategies to improve antibiotic prescribing and antibiotic stewardship programs should enable clinical reasoning and enhance the prescribing environment. In addition, the well-established association between antimicrobial usage and resistance should motivate efforts to develop antimicrobial treatment regimens that facilitate the evolution of resistance. This review discusses the role of antibiotics, their current application in human medicine, and how the resistance has evolved to the existing antibiotics based on the existing literature.

An assessment of knowledge and attitude toward antibiotic misuse by small-scale broiler farmers in Bogor, West Java, Indonesia.

Background and Aim: Antibiotics are often overused and misused by broiler farmers. Moreover, this practice may lead to antibiotic resistance. Antibiotics may be used for various purposes such as therapy, prophylaxis, flushing, and growth promoters. The study aimed to examine the association of knowledge and attitudes with antibiotics used by broiler farmers. Materials and Methods: The study design was cross-sectional. The data were obtained from interviewing 132 farmers' households in Bogor District, West Java, Indonesia. The outcome variable was antibiotic use, whereas the independent variables included knowledge and attitude toward antibiotic resistance. The statistical analysis used a t-test and correlation test. Results: A total of 78% of broilers farmers use antibiotics, and most of the farmers used antibiotics for flushing and prophylaxis. Furthermore, antibiotic use was associated with broiler farmers' knowledge and attitudes toward antibiotic resistance. However, there is no significant correlation between the duration of antibiotics use and their knowledge and attitude. Conclusion: The use of antibiotics in broilers is still high in Bogor, and most of the used antibiotics belong to the Medically Important Antimicrobial category. In general, the use of antibiotics in broilers is influenced by knowledge.

The Predictors Influencing the Rational Use of Antibiotics Among Public Sector: A Community-Based Survey in Thailand.

Background: The spread and emergence of antimicrobial resistance is the significant public health concerns over past decades. The major leading cause comes from irrational use of antibiotics. Aim: To explore the characteristics of rational use of antibiotics and identify its predictive factors among public sector living in Nakhon Nayok Province, Thailand. Methods: This project was conducted by using the data-source from Rational Use of Antibiotics (RUA) Survey Project at Nakhon Nayok Province. A cross-sectional community-based study method and face to face interviews were conducted. Two hundred fifty-four participants were selected by using Quota sampling method. Descriptive statistics were used to describe the sociodemographic and antibiotics use characteristics. Chi-square test were utilized to determine the association between explanatory variables and major outcome while multiple logistic regression was analysed to identify the predictors of antibiotics use behavior. Results: The mean age of the participants was 42 years, those with aged between 35 and 56 had more rational use of antibiotics behavior than those with 13-34 years while older adults (57-78 years) were significantly associated with irrational use of antibiotics [AOR = 0.38; 95% CI (0.17-0.85)] than those with less than 34 years of age. Less than half (45.7%) and about one third of them (31.1%) showed adequate knowledge and appropriate attitude towards antibiotics use. An adequate knowledge [AOR = 3.37; 95% CI (1.92-5.90)], appropriate attitude [AOR = 2.90; 95% CI (1.54-5.43)], not using antibiotics within last 3 months [AOR = 1.89; 95% CI (1.04-3.43)], and not visiting drugstore when having three main diseases [AOR = 2.04; 95% CI (1.06-3.92)] were the significant predictors of rational antibiotics use (p-value <0.05). Conclusion: Strategies development in terms of knowledge and attitude enhancement about antibiotics use particularly at the different ages together with RDU pharmacy encouragement and policy restriction of community drugstores antibiotics sales are the most effective method to promote rational antibiotics use behavior in the public sector.
