Antibiotic resistance spectrums of Escherichia coli and Enterococcus spp. strains against commonly used antimicrobials from commercial meat-rabbit farms in Chengdu City, Southwest China. Front Vet Sci 2024; 11:1369655. [PMID: 38756516 PMCID: PMC11096573 DOI: 10.3389/fvets.2024.1369655] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2024] [Accepted: 04/12/2024] [Indexed: 05/18/2024] Open
Abstract
Antimicrobial resistance (AMR) is commonly associated with the inappropriate use of antibiotics during meat-rabbit production, posing unpredictable risks to rabbit welfare and public health. However, there is limited research on the epidemiological dynamics of antibiotic resistance among bacteria indicators derived from local healthy meat-rabbits. To bridge the knowledge gap between antibiotic use and AMR distribution, a total of 75 Escherichia coli (E. coli) and 210 Enterococcus spp. strains were successfully recovered from fecal samples of healthy meat-rabbits. The results revealed that diverse AMR phenotypes against seven commonly used antimicrobials, including ampicillin (AMP), amoxicillin-clavulanic acid (A/C), doxycycline (DOX), enrofloxacin (ENR), florfenicol (FFC), gentamicin (GEN), and polymycin B (PMB), were observed among most strains of E. coli and Enterococcus spp. in two rabbit farms, although the distribution pattern of antibiotic resistance between young and adult rabbits was similar. Among them, 66 E. coli strains showed resistance against 6 antimicrobials except for PMB. However, 164 Enterococcus spp. strains only exhibited acquired resistance against DOX and GEN. Notably, the DOX-based AMR phenotypes for E. coli and Enterococcus spp. strains were predominant, indicating the existing environmental stress conferred by DOX exposure. The MICs tests suggested elevated level of antibiotic resistance for resistant bacteria. Unexpectedly, all GEN-resistant Enterococcus spp. strains resistant high-level gentamicin (HLGR). By comparison, the blaTEM, tetA, qnrS and floR were highly detected among 35 multi-resistant E. coli strains, and aac[6']-Ie-aph[2']-Ia genes widely spread among the 40 double-resistant Enterococcus spp. strains. Nevertheless, the presence of ARGs were not concordant with the resistant phenotypes for a portion of resistant bacteria. In conclusion, the distribution of AMR and ARGs are prevalent in healthy meat-rabbits, and the therapeutic antimicrobials use in farming practice may promote the antibiotic resistance transmission among indicator bacteria. Therefore, periodic surveillance of antibiotic resistance in geographic locations and supervisory measures for rational antibiotic use are imperative strategies for combating the rising threats posed by antibiotic resistance, as well as maintaining rabbit welfare and public health.

Characterization of Antibiotic Treatment among Children Aged 0-59 Months Hospitalized for Acute Bacterial Gastroenteritis in Israel. Antibiotics (Basel) 2024; 13:64. [PMID: 38247623 PMCID: PMC10812600 DOI: 10.3390/antibiotics13010064] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2023] [Revised: 12/22/2023] [Accepted: 01/04/2024] [Indexed: 01/23/2024] Open
Abstract
BACKGROUND We examined the extent and correlates of appropriate antibiotic use among children hospitalized with bacterial acute gastroenteritis (AGE) in Israel, a high-income country setting. METHODS Data were collected from children aged 0-59 months who participated in active hospital-based surveillance of AGE undertaken during 2007-2015. Bacterial AGE was defined as having a positive stool culture for Salmonella, Shigella, Campylobacter, or dysentery. Appropriate antibiotic use was defined as the administration of ciprofloxacin, azithromycin, or third-generation cephalosporins during hospitalization or at discharge. RESULTS Overall, 550 children had bacterial AGE; of those, 369 (67.1% [95% CI 63.1-70.9]) received antibiotics, mostly azithromycin (61.8%) and third-generation cephalosporins (37.9%). Appropriate antibiotic treatment was given to 318/550 (57.8% [95% CI 53.7-61.9]). Children aged 0-11 months vs. 24-49 months were more likely to receive appropriate antibiotic treatment (OR = 1.90 [95% CI 1.09-3.33]). Having dysentery (OR = 5.30 [95% CI 3.35-8.39]), performing blood culture (OR = 1.59 [95% CI 1.02-2.48]), and C-reactive protein (CRP) levels (OR = 1.01 [95% CI 1.01-1.02]) were positively associated with receiving appropriate antibiotic treatment. CONCLUSIONS Most children with bacterial AGE received appropriate antibiotic treatment, which correlated with young age, dysentery, CRP level, and performing blood culture, suggesting more severe illness, thus supporting the clinical decisions of physicians.

The therapy frequency of antibiotics and phenotypical resistance of Escherichia coli in calf rearing sites in Germany. Front Vet Sci 2023; 10:1152246. [PMID: 37275609 PMCID: PMC10233112 DOI: 10.3389/fvets.2023.1152246] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2023] [Accepted: 04/26/2023] [Indexed: 06/07/2023] Open
Abstract
Introduction The association between antibiotic use and the occurrence of resistant bacteria is a global health problem and is subject to enormous efforts at national and international levels. Within the scope of the study "KAbMon", the resistance situation as well as the use of antibiotics in calf rearing farms in Germany was investigated. We hypothesized that the levels of resistance are associated with certain calf keeping farm types, such as pre-weaned calf farms, animal groups, and therapy frequency. Methods In total, 95 calf keeping farms were visited between October 2019 and April 2021. At each farm, up to three pooled fecal samples (10 freshly released feces each) were collected. One sample was taken in the youngest calf group, another in the oldest calf group, and one in the hospital box, if available. Escherichia coli was isolated from non-selective MacConkey agar. The therapy frequency reflects the average number of treatment days per calf in a half-year, while the resistance score is the sum of the relative minimum inhibitory concentration per substance over all 10 tested substances. Results The 1781 isolates from 178 samples showed high resistance rates against sulfamethoxazole (82%), tetracycline (49%), and ampicillin (40%). High resistance scores were mainly found in pre-weaned calf farms (purchasing calves from 2 weeks of life) and in the youngest animals. The therapy frequency showed an almost linear relationship with the resistance scores, and the age at purchase was negatively related to the resistance score. Discussion The high use of antimicrobials of young calves might be associated with a high risk for infectious diseases and might indicate that the current system of crowding 14-day-old calves from different farms in one group is not optimal. Further efforts are necessary to educate and motivate the calf keepers to ensure highest levels of hygiene and management as well as animal welfare conditions and to increase animal health.

Growing threat of extended-spectrum β-lactamase-producing Enterobacteriaceae colonisation in high-risk pregnancies: A cross-sectional study. BJOG 2023; 130:415-423. [PMID: 35445798 DOI: 10.1111/1471-0528.17194] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2021] [Revised: 03/10/2022] [Accepted: 03/20/2022] [Indexed: 02/07/2023]
Abstract
OBJECTIVE To investigate the epidemiological changes in extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-E) vaginal colonisation in pregnant women deemed at high risk, and to identify independent risk factors. Further, the differences in perinatal outcomes according to maternal ESBL-E vaginal colonisation were analysed. DESIGN Cross-sectional study. SETTING Republic of Korea. POPULATION A cohort of 1460 women admitted to our high-risk pregnancy unit between 14+0 and 36+6 weeks of gestation. METHODS The trend of changes in the association of ESBL-E vaginal colonisation from January 2010 to December 2020 was analysed. The main outcomes were analysed over the study period and ESBL-E vaginal colonisation. MAIN OUTCOME MEASURES Rate of ESBL-E vaginal colonisation, risk factors for ESBL-E vaginal colonisation and perinatal outcomes. RESULTS The ESBL-E vaginal colonisation rate has tended to increase over the past 11 years, which was attributed to a significantly higher proportion of ESBL-producing Escherichia coli. Cerclage (RR 3.7, 95% CI 2.19-6.40) and prior antibiotic treatment (RR 4.0, 95% CI 2.44-6.54) were found as independent risk factors for ESBL-E vaginal colonisation. Earlier gestational age at delivery and higher proven early-onset neonatal sepsis (EONS) rate were observed in the ESBL-E-positive group. CONCLUSIONS The ESBL-E vaginal colonisation rate in pregnant patients at high risk has increased over the past decade, and the independent risk factors for colonisation are cerclage and prior antibiotic treatment. Additionally, maternal ESBL-E vaginal colonisation is associated with higher rates of proven EONS.

Applying the Kirkpatrick model to evaluate dental students' experience of learning about antibiotics use and resistance. EUROPEAN JOURNAL OF DENTAL EDUCATION : OFFICIAL JOURNAL OF THE ASSOCIATION FOR DENTAL EDUCATION IN EUROPE 2022; 26:756-766. [PMID: 34939280 DOI: 10.1111/eje.12758] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/31/2021] [Revised: 10/24/2021] [Accepted: 12/19/2021] [Indexed: 06/14/2023]
Abstract
INTRODUCTION "Antibiotic resistance" is of main concern in global health and that it could hinder the achievement of sustainable development goals. One of the reported contributing factors is the irrational prescribing behaviour of healthcare professionals including dentists. Efforts to design and evaluate effective educational programmes for undergraduate dental students about appropriate prescribing behaviour during their early educational years could mitigate the risk of antibiotic resistance. MATERIALS AND METHODS A total of 322 students participated in the study. Their knowledge of antibiotics and antibiotic resistance was assessed. Students received a specially designed, interactive educational programme. The success of the programme was assessed after the educational sessions and 2 years later using Kirkpatrick's four-level evaluation model. RESULTS This study is the first study to use Kirkpatrick model to evaluate an educational programme for dental students. The results of the first level of evaluation showed an overall satisfaction score of 82.1%. The second level revealed an increase in the percentage of correct answers after the educational sessions from 68.3% to 80%, and significant agreement with responsible antibiotics usage (p-value = .020, Effect size = 0.121). The third level showed that the percentage of correct answers 2 years later was 87.5%. The fourth level confirmed the success of the programme as 88.9% of participants reported using the knowledge gained from the programme when prescribing antibiotics. CONCLUSIONS Our study emphasises the success of the used educational programme and highlights the need for educational interventions in the under graduate dental curriculum.

The impact of pharmacist-led antimicrobial stewardship program on antibiotic use in a county-level tertiary general hospital in China: A retrospective study using difference-in-differences design. Front Public Health 2022; 10:1012690. [PMID: 36262226 PMCID: PMC9574199 DOI: 10.3389/fpubh.2022.1012690] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2022] [Accepted: 09/05/2022] [Indexed: 01/27/2023] Open
Abstract
Background Inappropriate use of antibiotics has become a major driver for the spread of antimicrobial resistance globally, particularly common in China. Antimicrobial stewardship programs are effective in optimizing antimicrobial use and decreasing the emergence of multi-drug-resistant organisms, and the pharmacist has performed a leading role in this program. Objective To evaluate the impact of antimicrobial stewardship programs driven by pharmacists on antibiotic consumption and costs and the appropriateness of antibiotic use. Methods A single-center retrospective quasi-experimental design was conducted in two independent hepatobiliary surgery wards and two independent respiratory wards in a county-level tertiary general hospital in Jiangsu, China. Each intervention group was served with antimicrobial stewardship programs with prescriptions audit and feedback, antibiotics restriction, education, and training. The propensity score matching method was employed to balance confounding variables between the intervention group and control group, and a difference-in-differences analysis was used to evaluate the impact of antimicrobial stewardship programs. The primary outcome was measured by scores of rationality evaluation of antibiotics. Results The DID results demonstrated that the implementation of the antimicrobial stewardship programs was associated with a reduction in the average length of hospital stay (coefficient = -3.234, p = 0.006), DDDs per patient (coefficient = -2.352, p = 0.047), and hospitalization costs (coefficient = -7745.818, p = 0.005) in the hepatobiliary surgery ward, while it was associated with a decrease in DDDs per patient (coefficient = -3.948, p = 0.029), defined daily doses per patient day (coefficient = -0.215, p = 0.048), and antibiotic costs (coefficient = -935.087, p = 0.014) in the respiratory ward. The program was also associated with a decrease in rationality evaluation scores (p < 0.001) in two wards. Conclusion The result reveals that the implementation of the antimicrobial stewardship programs is effective in reducing the length of hospital stay, decreasing antibiotics consumption and costs, and improving the appropriateness of antimicrobial use such as decreasing irrational use of cephalosporins, reducing combinations, and improving timely conversion. However, great attention ought to be paid to the improper use of broad-spectrum antibiotics. The government is responsible for providing sustainable formal education for pharmacists, and more funding and staff support to promote antimicrobial stewardship programs.

Parents' awareness of antimicrobial resistance: a qualitative study utilising the Health Belief Model in Perth, Western Australia. Aust N Z J Public Health 2022; 46:764-770. [PMID: 35679064 DOI: 10.1111/1753-6405.13265] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2021] [Revised: 04/01/2022] [Accepted: 04/01/2022] [Indexed: 11/28/2022] Open
Abstract
OBJECTIVE This study aimed to determine local factors that promote or prevent parents' responsible use of antibiotics for their children in Perth, Western Australia. METHODS The Health Belief Model was used to guide this study. Four focus group discussions were conducted, with 26 participants. Participants were recruited purposively through a parent group organisation. The Framework Method was utilised to analyse the data. RESULTS Participants agreed that antimicrobial resistance (AMR) is a serious health problem. However, participants admitted that they lacked awareness of AMR, inhibiting their ability to assess the risks of developing AMR infections among their children. Participants knew the indications and risks of antibiotic use but still viewed antibiotics as a time-saving solution that minimised disruption to their routine. Participants' previous experiences in managing their children's illness increased their confidence and linked their positive and negative experiences with their general practitioners in their judicious use of antibiotics. CONCLUSIONS While parents demonstrated awareness of the indications of antibiotics, they continue to lack AMR awareness and overvalue antibiotics. IMPLICATIONS FOR PUBLIC HEALTH The findings highlight that incorporating parent empowerment and participation in decision-making regarding antibiotics use, and maintaining a positive relationship with healthcare providers, were important strategies to encourage the appropriate use of antibiotics.

The Impact of a Multifaceted Pharmacist-Led Antimicrobial Stewardship Program on Antibiotic Use: Evidence From a Quasi-Experimental Study in the Department of Vascular and Interventional Radiology in a Chinese Tertiary Hospital. Front Pharmacol 2022; 13:832078. [PMID: 35295325 PMCID: PMC8919369 DOI: 10.3389/fphar.2022.832078] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2021] [Accepted: 01/13/2022] [Indexed: 11/13/2022] Open
Abstract
Objective: The objective of the study was to assess the impact of multifaceted clinical pharmacist-led antimicrobial stewardship (AMS) program on the rational use of antibiotics for patients who receive vascular and interventional radiology therapies. Methods: A quasi-experimental retrospective intervention design with a comparison group was applied to the practice of antibiotic use in the department of vascular and interventional radiology in a Chinese tertiary hospital. We used difference-in-differences (DID) analysis to compare outcomes before and after the AMS intervention between the intervention group and control group, to determine whether intervention would lead to changes in irrationality of antibiotic prescribing, antibiotic utilization, cost of antibiotics, and length of hospital stay. Results: The DID results showed that the intervention group was associated with a reduction in the average consumption of antibiotics (p = 0.017) and cost of antibiotics (p = 0.006) and cost per defined daily dose (DDD) (p = 0.000). There were no significant differences in the mean change of total costs and length of stay between the two groups (p > 0.05). The average inappropriate score of perioperative antimicrobial prophylaxis in the intervention group declined by 0.23, while it decreased by 0.02 in the control group [0.21 (95% CI, -0.271 to -0.143); p = 0.000]. The average inappropriate score of non-surgical antimicrobial prophylaxis in the intervention group declined by 0.14, while it increased by 0.02 in the control group [0.16 (95% CI, -0.288 to -0.035); p = 0.010]. The average inappropriate score of the therapeutic use of antibiotics in the intervention group declined by 0.07, while it decreased by 0.01 in the control group [0.06 (95% CI, -0.115 to -0.022); p = 0.003]. Conclusions: This study provides evidence that implementation of AMS interventions was associated with a marked reduction of antibiotic use, cost of antibiotics, and irrationality of antibiotic prescribing in China.

Exploring Undergraduate Pharmacy Students Perspectives Towards Antibiotics Use, Antibiotic Resistance, and Antibiotic Stewardship Programs Along With the Pharmacy Teachers' Perspectives: A Mixed-Methods Study From Pakistan. Front Pharmacol 2021; 12:754000. [PMID: 34819859 PMCID: PMC8606649 DOI: 10.3389/fphar.2021.754000] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2021] [Accepted: 10/13/2021] [Indexed: 11/13/2022] Open
Abstract
Background: Antibiotic resistance (ABR) is one of the major issues around the globe. Timely education and awareness of pharmacy students regarding the appropriate use of antibiotics, ABR, and antimicrobial stewardships are required. Methods: The present study was first conducted in 12 (public and private sector) universities among undergraduate pharmacy students (UGPS) (n = 414) irrespective of their study year through a validated questionnaire, and the insights of pharmacy teachers were taken through in-depth semi-structured interviews in the second phase. For the quantitative data, different statistical methods were used, and data were presented in tabulated form, whereas inductive thematic interpretation was used to categorize themes and derive conclusions from qualitative evidence. Results: The majority of the students were males (n = 223, 54%) with the mean age group 19–23 years, and 20 faculty members were interviewed with a mean duration of 15 min. Students have good knowledge about antibiotics use and the majority purchased antibiotics through prescription (n = 277, 66.9%) during the last month and strongly agreed to stop unnecessary household storage (n = 183 44.2%). Most of the students have heard the terminologies related to antimicrobial resistance through social media while unaware (n = 104, 25.1%) of a Pakistan national action plan against AMR (antimicrobial resistance). Overall, respondents have a somewhat good understanding of the ABR. Regular use of antibiotics without consultation of a physician can lead to ABR and some wrong answers were observed (162, 39.1%; p > 0.05). The majority of the students (n = 198, 47.8%) and teachers believe that the current pharmacy syllabus must be swiftly updated with the new subjects related to ABR and AMS (antimicrobial stewardship) in Pakistan. The UGPS have emphasized (n = 220, 53.1%; Median = 1, IQR = 2) establishing a link between academia and hospitals. The ABR issue has been highlighted by pharmacy faculty members, who have urged students to take practical efforts toward ABR and AMS knowledge. Conclusion: The UGPS knowledge related to ABR and AMS must be updated. Students at the undergraduate level must get training in order to encourage the sensible use of antibiotics. Courses on ABR and AMS should be included in present pharmacy curricula.

Abstract
Objectives: This study aimed to identify the trends in antibiotics utilization and patients costs, evaluating the effect of the policy and exploring factors associated with the irrational use of antibiotics. Methods: Based on the Cooperation Project Database of Hospital Prescriptions, data were collected from 89 tertiary hospitals in nine cities in China during 2016-2019. The study sample consisted of prescription records with antibiotics for 3,422,710 outpatient and emergency visits and 26, 118, 436 inpatient hospitalizations. Results: For outpatients, the proportion of treated with antibiotics declined from 14.72 to 13.92% significantly (p < 0.01). The proportion of antibiotic costs for outpatients decreased from 5.79 to 4.45% significantly (p < 0.01). For emergency patients, the proportion of treated with antibiotics increased from 39.31 to 43.45% significantly (p < 0.01). The proportion of antibiotic costs for emergency patients decreased from 36.44 to 34.69%, with no significant change (p = 0.87). For inpatients, the proportion of treated with antibiotics increased from 23.82 to 27.25% significantly (p < 0.01). The proportion of antibiotic costs for outpatients decreased from 18.09 to 17.19% with no statistical significance (p = 0.89). Other β-lactam antibacterials (1,663.03 ten thousand DDD) far exceeded other antibiotics categories. Stablely ranked first, followed by Macrolides, lincosamide and streptogramins (965.74 ten thousand DDD), Quinolone antibacterials (710.42 ten thousand DDD), and β-lactam antibacterials, penicillins (497.01 ten thousand DDD). Conclusions: The proportion of treated with antibiotics for outpatients and inpatients meet the WHO standards. The antibiotics use varied by different survey areas, clinical departments, patient gender, patient age and antibiotics categories. More efforts should focus on improving the appropriateness of antibiotics use at the individual level.

PBPK Modeling and Simulation of Antibiotics Amikacin, Gentamicin, Tobramycin, and Vancomycin Used in Hospital Practice. Life (Basel) 2021; 11:life11111130.

Abstract
The importance of closely observing patients receiving antibiotic therapy, performing therapeutic drug monitoring (TDM), and regularly adjusting dosing regimens has been extensively demonstrated. Additionally, antibiotic resistance is a contemporary concerningly dangerous issue. Optimizing the use of antibiotics is crucial to ensure treatment efficacy and prevent toxicity caused by overdosing, as well as to combat the prevalence and wide spread of resistant strains. Some antibiotics have been selected and reserved for the treatment of severe infections, including amikacin, gentamicin, tobramycin, and vancomycin. Critically ill patients often require long treatments, hospitalization, and require particular attention regarding TDM and dosing adjustments. As these antibiotics are eliminated by the kidneys, critical deterioration of renal function and toxic effects must be prevented. In this work, clinical data from a Portuguese cohort of 82 inpatients was analyzed and physiologically based pharmacokinetic (PBPK) modeling and simulation was used to study the influence of different therapeutic regimens and parameters as biological sex, body weight, and renal function on the biodistribution and pharmacokinetic (PK) profile of these four antibiotics. Renal function demonstrated the greatest impact on plasma concentration of these antibiotics, and vancomycin had the most considerable accumulation in plasma over time, particularly in patients with impaired renal function. Thus, through a PBPK study, it is possible to understand which pharmacokinetic parameters will have the greatest variation in a given population receiving antibiotic administrations in hospital context.

Abstract
Evidence based information sources for physicians are needed for informed antibiotic prescribing practices. The aim of this study was to explore physicians' preferred sources of information and evaluate physicians' awareness of available information and initiatives on prudent antibiotic prescribing in Jordan. A cross-sectional study was conducted utilizing an online questionnaire and included physicians (n = 409) from all sectors and specialties in Jordan. Published guidelines (31.8%), the workplace (25.7%), colleagues or peers (20.0%), group or conference training (18.3%), and the medical professional body (18.1%) were the main sources of information about avoiding unnecessary antibiotic prescribing, with the influence of these sources on changing prescribers' views being 34.7%, 17.1%, 11%, 13.4%, and 7.6%, respectively. One-third of physicians (33.7%) reported no knowledge of any initiatives on antibiotic awareness and resistance. Regarding awareness of national action plans on antimicrobial resistance, 10.5%, 34%, and 55.5% of physicians were aware, unaware, and unsure of the presence of any national action plans, respectively. Physicians showed interest in receiving more information on resistance to antibiotics (58.9%), how to use antibiotics (42.2%), medical conditions for which antibiotics are used (41.3%), prescribing of antibiotics (35.2%), and links between the health of humans, animals, and the environment (19.8%). The findings can inform interventions needed to design effective antimicrobial stewardship, enabling physicians to prescribe antibiotics appropriately.

Educational Video Improves Knowledge about Outpatients' Usage of Antibiotics in Two Public Hospitals in Indonesia. Antibiotics (Basel) 2021; 10:606. [PMID: 34065353 PMCID: PMC8161411 DOI: 10.3390/antibiotics10050606] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2021] [Revised: 05/12/2021] [Accepted: 05/18/2021] [Indexed: 11/29/2022] Open
Abstract
The inappropriate use or misuse of antibiotics, particularly by outpatients, increases antibiotic resistance. A lack of public knowledge about "Responsible use of antibiotics" and "How to obtain antibiotics" is a major cause of this. This study aimed to assess the effectiveness of an educational video about antibiotics and antibiotic use to increase outpatients' knowledge shown in two public hospitals in East Java, Indonesia. A quasi-experimental research setting was used with a one-group pre-test-post-test design, carried out from November 2018 to January 2019. The study population consisted of outpatients to whom antibiotics were prescribed. Participants were selected using a purposive sampling technique; 98 outpatients at MZ General Hospital in the S regency and 96 at SG General Hospital in the L regency were included. A questionnaire was used to measure the respondents' knowledge, and consisted of five domains, i.e., the definition of infections and antibiotics, obtaining the antibiotics, directions for use, storage instructions, and antibiotic resistance. The knowledge test score was the total score of the Guttman scale (a dichotomous "yes" or "no" answer). To determine the significance of the difference in knowledge before and after providing the educational video and in the knowledge score between hospitals, the (paired) Student's t-test was applied. The educational videos significantly improved outpatients' knowledge, which increased by 41% in MZ General Hospital, and by 42% in SG General Hospital. It was concluded that an educational video provides a useful method to improve the knowledge of the outpatients regarding antibiotics.

Developing a Sustainable Antimicrobial Stewardship (AMS) Programme in Ghana: Replicating the Scottish Triad Model of Information, Education and Quality Improvement. Antibiotics (Basel) 2020; 9:antibiotics9100636. [PMID: 32977691 PMCID: PMC7598579 DOI: 10.3390/antibiotics9100636] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2020] [Revised: 09/17/2020] [Accepted: 09/22/2020] [Indexed: 11/16/2022] Open
Abstract
(1) Background: Our aim was to develop robust and reliable systems for antimicrobial stewardship (AMS) in Keta Municipal Hospital and Ghana Police Hospital. Objectives were to build capacity through training staff in each hospital, establish AMS teams, collect data on antibiotic use and support local quality improvement initiatives. (2) Methods: The Scottish team visited Ghana hospitals on three occasions and the Ghanaian partners paid one visit to Scotland. Regular virtual meetings and email communication were used between visits to review progress and agree on actions. (3) Results: Multi-professional AMS teams established and met monthly with formal minutes and action plans; point prevalence surveys (PPS) carried out and data collected informed a training session; 60 staff participated in training delivered by the Scottish team and Ghanaian team cascaded training to over 100 staff; evaluation of training impact demonstrated significant positive change in knowledge of antimicrobial resistance (AMR) and appropriate antibiotic use as well as improved participant attitudes and behaviours towards AMR, their role in AMS, and confidence in using the Ghana Standard Treatment Guidelines and antimicrobial app. (4) Conclusions: Key objectives were achieved and a sustainable model for AMS established in both hospitals.

Antibiotic Use Associated with Confirmed Influenza, Pertussis, and Nontyphoidal Salmonella Infections. Microb Drug Resist 2020; 26:1482-1490. [PMID: 32315565 DOI: 10.1089/mdr.2020.0017] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/16/2023] Open
Abstract
Purpose: Antibiotics are not the recommended treatment for uncomplicated influenza or nontyphoidal salmonella infections, whereas they are for current pertussis infection. We investigated adherence to these recommendations in a population of older community-dwelling adults. Methods: Population-based prospective cohort study of Australian adults 45 years of age and older followed by record-linkage to laboratory-confirmed influenza, pertussis, and nontyphoidal salmonella notifications, hospitalization records, and antibiotic dispensing data from January 1, 2009 to December 31, 2015. Proportions of those with infections who were prescribed antibiotics were estimated, and characteristics associated with antibiotic prescribing were examined. Results: There were 1,056 influenza, 151 pertussis, and 334 nontyphoidal salmonella cases in the cohort eligible for analysis. Antibiotics were dispensed in 56.2% (594/1,056) of influenza, 78.8% (119/151) of pertussis, and 39.5% (132/334) of nontyphoidal salmonella cases within the ±10-day window around the infection onset date. The likelihood of antibiotic dispensing did not differ according to most participant characteristics examined, including whether cases had an associated hospitalization, their age, and recorded comorbidities. Macrolides were the predominant class of antibiotics dispensed for pertussis (79%), whereas both beta-lactams (36.3%) and macrolides (35.4%) were used for cases of influenza. There was no dominant antibiotic class dispensed among those with nontyphoidal salmonella. Conclusions: Given concerns regarding increasing antibiotic resistance, the high proportion of adults with influenza and nontyphoidal salmonella cases dispensed antibiotics indicate the need for further strengthening of antimicrobial stewardship by raising education and awareness of guidelines for managing these infections.

Knowledge of Antimicrobial Resistance among Veterinary Students and Their Personal Antibiotic Use Practices: A National Cross-Sectional Survey. Antibiotics (Basel) 2019; 8:antibiotics8040243. [PMID: 31795341 PMCID: PMC6963658 DOI: 10.3390/antibiotics8040243] [Citation(s) in RCA: 28] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2019] [Revised: 11/17/2019] [Accepted: 11/20/2019] [Indexed: 02/05/2023] Open
Abstract
The challenge of antimicrobial resistance (AMR) is grave in developing countries. Antimicrobials are misused yet stakeholders' contribution to antimicrobial stewardship is low. Veterinary students are future prescribers and their knowledge could influence progress in combating AMR; hence, there is a need to assess their knowledge, attitude, and awareness of AMR. A multi-institutional questionnaire was administered to undergraduates in Nigerian veterinary schools. It comprised demographics, own personal antibiotic usage, and knowledge, attitude, and awareness of AMR in humans and animals. Descriptive statistics and logistic regression were used for analyses. Of the 426 respondents, 39.2% reported personal antimicrobial use in the previous six months. Over 60% received knowledge scores lower than average and >87% requested more education on clinical use and prescriptions pre-graduation, monitored dispensing of antimicrobials, conducting AMR research, and confirmed link among human, animal, and environmental health. Less than 25% of respondents were aware of antimicrobial stewardship and global efforts/organizations for AMR. Final year students have 9-fold and 14-fold more satisfactory knowledge on antimicrobials in humans and animals compared with other students, respectively (p = 0.001). Final year students also have more knowledge (13×) and awareness of contributory factors (3×) on AMR (p = 0.001) than other students. Unsatisfactory knowledge on AMR issues exists among veterinary students yet willingness to improve was observed. Identified knowledge, attitude, and gaps in AMR awareness should be targeted by veterinary schools in Nigeria.

Ability of serum procalcitonin to distinguish focus of infection and pathogen types in patients with bloodstream infection. ANNALS OF TRANSLATIONAL MEDICINE 2019; 7:135. [PMID: 31157256 DOI: 10.21037/atm.2019.03.24] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 12/30/2022]
Abstract
Background Serum procalcitonin (PCT) is a widely recognized inflammatory marker which can distinguish systemic bacterial infection from other types of infections. The ability of PCT levels to distinguish different pathogens from different focus of infection is contradictory. Methods This study included 551 patients with bloodstream infection (BSI) diagnosed with positive blood culture (BC) during Jan 2013 and May 2018. The patients were divided into two groups with or without definite focus of infection. In this study, we analyzed PCT levels induced by Gram-positive bacteria, Gram-negative bacteria and fungal infection. Relationship of time between PCT peak and BC collection, and the impact of antibiotics usage on PCT peak distribution were examined. Results For patients without definite focus of infection, the serum PCT values of Gram-negative bacteria were higher than that of Gram-positive bacteria (P<0.05). A cut-off value of 7.54 ng/mL for PCT showed a sensitivity of 88.3%. For patients with definite focus of infection, the serum PCT values of Gram-negative bacteria were significantly higher than Gram-positive bacteria in patients with lower respiratory tract (P=0.003), abdominal (P=0.039), urinary tract infection (P=0.025), but not in patients with upper respiratory tract infection (P=0.664). The PCT values between multidrug-resistant organism (MDRO) and sensitive bacteria were not statistically significant (P>0.05) among all patients. Moreover, among patients who use antibiotics before BC collection, the longer antibiotics used, the higher trend of the proportion for PCT peak distribution after BC collection. The higher proportion of antibiotics combined before BC collection, the lower proportion of PCT peak distribution appeared before BC collection, and the higher the proportion of PCT peak distribution appeared after BC collection. Conclusions PCT value is determined by many factors. PCT value is related to not only Gram-positive bacteria or Gram-negative bacteria, but also related to specific pathogens, and specific of infection sites etc. The use of Antibiotics is also an important factor of PCT value.

Are systemic antibiotics necessary in the prevention of wound healing complications after intra-alveolar dental extraction? Int J Oral Maxillofac Surg 2016; 45:1658-1664. [PMID: 27746007 DOI: 10.1016/j.ijom.2016.08.023] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2015] [Revised: 07/07/2016] [Accepted: 08/24/2016] [Indexed: 11/23/2022]
Abstract
This double-blind, randomized controlled study was done to assess the necessity of systemic antibiotics in the prevention of wound healing complications after intra-alveolar dental extraction. A consecutive recruitment method was used to allocate participants to two treatment groups. Subjects in group A (antibiotics group, n=75) received amoxicillin and metronidazole for 5 days postoperatively, while those in group B (placebo group, n=75) were given identical-looking placebo drugs in place of the antibiotics. Postoperative socket healing complications, pain, and compliance with postoperative instructions were assessed postoperatively. Healing was uneventful in 129 patients (86%). Twenty-one patients (14%) developed wound healing complications. Dry socket was the most common complication in the antibiotics group (six subjects), while acutely inflamed sockets was the most common in the placebo group (five subjects). Non-adherence to postoperative instructions and postoperative pain were found to be significantly associated with the development of wound healing complications. The prescription of antibiotics after routine intra-alveolar dental extraction in healthy patients may not play any significant role in preventing wound healing complications. However, non-compliance with postoperative instructions might be associated with increased wound healing complications.

Abstract
OBJECTIVE To investigate the present situation of antibiotics use in selected hospitals in China according to 2 indicators: hospital-based market sales and frequency of usage; based on this information, to assess the government's containment policies toward antibiotics overuse. METHODS Marketing and clinical usage data of antibiotics in 420 selected hospitals from 21 major cities and 1 district in China during 2008-2011 were collected and analyzed. Usage frequency was measured by the defined daily dose (DDD) analytic approaches recommended by World Health Organization (WHO), and the growth rate of DDDs per patient was compared for 3 categories of antibiotics: nonlimited (first line), limited (second line), and specially controlled (third line). RESULTS During the period studied, an obvious slowdown was observed in both sales value and the growth of sales volume for the 3 categories. With respect to frequency, both limited-level and specially controlled level antibiotics with high cost and low safety and effectiveness showed an evident decline in the growth rate of DDDs per patient ( P < .05). However, no significant decline was found for nonlimited antibiotics ( P > .05). CONCLUSION The Chinese government's containment policies toward antibiotics overuse are beginning to take effect, and antibiotics usage has become more measured in major cities. However, China still has a long way to go before it can win the battle against antibiotics overuse and drug resistance.
