Children frequently succumb to illness and are often treated with antibiotic medicines which may be used improperly by the parent. There is limited evidence of the factors influencing parental decision-making about the use of antibiotics in low-resource contexts. The aim of this systematic review was to understand and describe how parents living in rural and remote locations make choices about their children’s antibiotic use. The CINAHL, Web of Science, Medline, Scopus and Academic Search Premier databases were systematically searched from 31 January until 28 June in 2023. No date restrictions were applied and additional search methods were utilised to identify further studies that met inclusion criteria. Eligibility criteria included studies which reported on factors contributing to parental decisions about their children’s use of antibiotics in rural and remote settings. The Joanna Briggs Institute Critical Appraisal Checklists were employed to evaluate studies. Characteristics and findings were extracted from studies, and data was synthesised descriptively and presented in summary tables. A total of 3827 articles were screened and 25 worldwide studies comprising of quantitative, qualitative and prospective designs were included in the review. Studies that reported the number of rural caregivers consisted of 12 143 participants. Data analysis produced six broad themes representing the mechanisms that influenced parents in their access and use of antibiotics: the child’s symptoms; external advice and influences; parent-related determinants; barriers to healthcare; access to antibiotics; and socio-demographic characteristics. A number of factors that influence parents’ prudent use of antibiotics in rural contexts were identified. In seeking to enhance appropriate use of antibiotics by parents in rural and remote settings, these determinants can serve to inform interventions. However, the identified studies all relied upon parental self-reports and not all studies reviewed reported survey validation. Further research incorporating validated measures and intervention strategies is required. Should my child be given antibiotics?

The distribution of antibiotics in absence of a prescription in pharmacies is a significant contributor to the growing global public health crisis of antibiotic resistance. A pharmacist’s clinical and lawful knowledge of antibiotic provide has an impact on the proper way to dispense medication. There are few novel studies assessing pharmacists comprehension and experience in prescribing antibiotics in low- and middle-income countries, including those in the Arabian region. (I) assess pharmacy team members Knowledge about antibiotics as reported by individuals themselves and their behavior in dispensing antimicrobial without a prescription and (ii) find potential influences on this behavior. Pharmacists were chosen from various regions in Algeria, Bahrain, Egypt, Iraq, Jordan, Kuwait, Lebanon, Libya, Morocco, Oman, Palestine, Qatar, Saudi Arabia, Somalia, Sudan, Syria, Tunisia, the United Arab Emirates, and Yemen, based on their convenience and ease of access. A descriptive cross-sectional assessment among a random sample (n = 2833) of community pharmacists was conducted Utilizing a structured, validated, and questionnaire that underwent pilot testing, a comprehensive survey with four distinct sections covering biography, knowledge, practice, and attitude domains was employed. Measures were knowledge, attitude, and practice toward dispensing antibiotics without prescription. Of the 3100 pharmacists reached, 2833 completed and return the questionnaires (response rate 91.3%). Most of the respondents were male (57.4%). Aged between 19 and 31 years old (76.2%). Most of them held a B.Sc. Degree (78.5%). Worked as staff pharmacists (73.2%). During the survey, it was discovered that there were gaps in their knowledge regarding antibiotic usage. A total of 45.7% of the respondents were unaware that antibiotics can be used as prophylaxis, while 33.3% did not recognize the consequences of making incorrect antibiotic choices. Regarding their practice patterns, 53.8% of the pharmacists admitted that they did not consistently adhere to guidelines when dispensing antibiotics. In terms of attitudes toward antibiotic usage, 36.8% disagreed with the guidelines of not supply antibiotics without a prescription, suggesting some variation in opinions among pharmacists on this matter. Additionally, a significant percentage (75%) believed that community pharmacists had qualifications to prescribe antibiotics for infections. The recent survey has shed light on the differences among pharmacists in regard to dispensing antibiotics without prescriptions and their understanding of resistance.

The IPCAF reflects the eight WHO core components (CC) of IPC. Besides facility self-assessment, the IPCAF can be used for national surveys, and repeated usage can aid in describing trends concerning IPC structures. A previous survey in over 700 German hospitals conducted in 2018, yielded an overall high IPC level in participating hospitals, albeit with potentials for improvement. In 2023, the survey was repeated to describe once again the state of IPC implementation in German hospitals and compare findings to data from 2018. The German National Reference Center for the Surveillance of Nosocomial Infections (NRC) invited 1,530 German acute care hospitals participating in the national surveillance network “KISS”, to complete a translated online version of the IPCAF between October 2023 and January 2024. The questionnaire-like nature of the IPCAF, where each answer corresponds to a number of points, allows for calculating an overall IPC score. Based on the overall score, hospitals were allocated to four different IPC levels: inadequate (0–200), basic (201–400), intermediate (401–600), and advanced (601–800). Aggregated scores were calculated and compared with results from 2018. Complete datasets from 660 hospitals were received and analyzed. The median overall IPCAF score was 692.5 (interquartile range: 642.5–737.5), with 572 hospitals (86.6%) classified as advanced, and 87 hospitals (13.2%) as intermediate. One hospital (0.2%) fell into the basic category. The overall median score was virtually unchanged when compared to 2018 (690; data from 736 hospitals). The median score for the CC on workload, staffing and bed occupancy was markedly higher (85 vs. 75), whereas the median score for the CC on multimodal strategies was slightly lower than in 2018 (75 vs. 80). Repeated assessments of IPC structures at the national level with the IPCAF are feasible and a means to gain insights into the evolution of IPC structures. When comparing aggregated scores, a stable and high level of IPC key aspects in Germany was observed, with improvements over time in IPC indicators related to workload and staffing.","PeriodicalId":501612,"journal":{"name":"Antimicrobial Resistance & Infection Control","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142226319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From 2013 to 2022, yearly point prevalence surveys were conducted in a large Dutch teaching hospital. On the day of the survey, all admitted patients were screened for ESBL-E rectal carriage using peri-anal swabs and a consistent and sensitive selective culturing method. All Enterobacterales phenotypically suspected of ESBL production were analysed using whole genome sequencing for ESBL gene detection and clonal relatedness analysis. On average, the ESBL-E prevalence was 4.6% (188/4,119 patients), ranging from 2.1 to 6.6% per year. The ESBL-prevalence decreased on average 5.5% per year. After time trend correction, the prevalence in 2016 and 2020 was lower compared to the other year. Among the ESBL-E, Escherichia coli (80%) and CTX-M genes (85%) predominated. Potential nosocomial transmission events could be found in 5.9% (11/188) of the ESBL-E carriers. The ESBL-E rectal carriage prevalence among hospitalized patients was 4.6% with a downward trend from 2013 to 2022. The decrease in ESBL-E prevalence in 2020 could have been due to the COVID-19 pandemic and subsequent countrywide measures as no nosocomial transmission events were detected in 2020. However, the persistently low ESBL-E prevalences in 2021 and 2022 suggest that the decline in ESBL-E prevalence goes beyond the COVID-19 pandemic, indicating that overall ESBL-E carriage rates are declining over time. Continuous monitoring of ESBL-E prevalence and transmission rates can aid infection control policy to keep antibiotic resistance rates in hospitals low.","PeriodicalId":501612,"journal":{"name":"Antimicrobial Resistance & Infection Control","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142207509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A comprehensive search was conducted in multiple databases, including PubMed, Scopus, Embase, Hinari (Research4Life) and Google Scholar. Studies reporting the point prevalence of antimicrobial prescription or use in healthcare settings using validated PPS tools were included. The quality of the studies was assessed using the Joanna Briggs Institute (JBI) critical appraisal checklist. A random-effects meta-analysis was conducted to combine the estimates. Heterogeneity was evaluated using Q statistics, I² statistics, meta-regression, and sensitivity analysis. Publication bias was assessed using a funnel plot and Egger’s regression test, with a p-value of < 0.05 indicating the presence of bias. Out of 1790 potential studies identified, 32 articles were included in the meta-analysis. The pooled prescription rate in acute care hospitals was 60%, with significant heterogeneity (I2 = 99%, p < 0.001). Therapeutic prescriptions constituted 62% of all the prescribed antimicrobials. Prescription quality varied: documentation of reasons in notes was 64%, targeted therapy was 10%, and parenteral prescriptions were 65%, with guideline compliance at 48%. Hospital-acquired infections comprised 20% of all prescriptions. Subgroup analyses revealed regional disparities in antimicrobial prescription prevalence, with Western Africa showing a prevalence of 65% and 44% in Southern Africa. Publication bias adjustment estimated the prescription rate at 54.8%, with sensitivity analysis confirming minor variances among studies. This systematic review and meta-analysis provide valuable insights into antimicrobial utilization in African health facilities.

We looked at the intersection of IPC, WASH, and the global initiative of improving health care quality, specifically around maternal and newborn care in Bangladesh health facilities. We identified 8 primary quality improvement and IPC/WASH policy and guideline documents in Bangladesh and analyzed their incorporation of 30 subconditions under 5 critical conditions: water; sanitation; hygiene; waste management/cleaning; and IPC supplies, guidelines, training, surveillance, and monitoring. To determine how Bangladesh health care workers implemented the policies, we interviewed 33 informants from 16 public and private facilities and the national level. Bangladesh’s 8 primary guidance documents covered 55% of the 30 subconditions. Interviews showed that Bangladesh health facility staff generally rely on eight tools related to quality improvement (five); IPC (two); and supportive supervision (one) plus a robust supervision mechanism. The stakeholders identified a lack of human resources and environmental hygiene infrastructure and supplies as the main gaps in providing IPC/WASH services. We concluded that the Bangladesh government had produced substantial guidance on using quality improvement methods to improve health services. Our recommendations can help identify strategies to better integrate IPC/WASH in resources including standardizing guidelines and tools within one toolkit. Strategizing with stakeholders working on initiatives such as universal health coverage and patient safety to integrate IPC/WASH into quality improvement documents is a mutually reinforcing approach.","PeriodicalId":501612,"journal":{"name":"Antimicrobial Resistance & Infection Control","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142207483","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Even though it is not preventable, antimicrobial stewardship (AMS) programmes will reduce or slow it down. Research evidence from Sierra Leone has demonstrated the high use of antibiotics in hospitals, but no study has assessed hospital AMS programmes and antibiotic use specifically among children. We conducted the first-ever study to assess the AMS programmes and antibiotics use in two tertiary hospitals in Sierra Leone. This was a hospital-based cross-sectional survey using the World Health Organization (WHO) point prevalence survey (PPS) methodology. Data was collected from the medical records of eligible patients at the Ola During Children’s Hospital (ODCH) and Makeni Regional Hospital (MRH) using the WHO PPS hospital questionnaire; and required data collection forms. The prescribed antibiotics were classified according to the WHO Access, Watch, and Reserve (AWaRe) classification. Ethics approval was obtained from the Sierra Leone Ethics and Scientific Review Committee. Statistical analysis was conducted using the SPSS version 22. Both ODCH and MRH did not have the required AMS infrastructure; policy and practice; and monitoring and feedback mechanisms to ensure rational antibiotic prescribing. Of the 150 patients included in the survey, 116 (77.3%) were admitted at ODCH and 34 (22.7%) to MRH, 77 (51.3%) were males and 73 (48.7%) were females. The mean age was 2 years (SD=3.5). The overall prevalence of antibiotic use was 84.7% (95% CI: 77.9% – 90.0%) and 77 (83.8%) of the children aged less than one year received an antibiotic. The proportion of males that received antibiotics was higher than that of females. Most (58, 47.2 %) of the patients received at least two antibiotics. The top five antibiotics prescribed were gentamycin (100, 27.4%), ceftriaxone (76, 20.3%), ampicillin (71, 19.5%), metronidazole (44, 12.1%), and cefotaxime (31, 8.5%). Community-acquired infections were the primary diagnoses for antibiotic prescription. The non-existence of AMS programmes might have contributed to the high use of antibiotics at ODCH and MRH. This has the potential to increase antibiotic selection pressure and in turn the AMR burden in the country. There is need to establish hospital AMS teams and train health workers on the rational use of antibiotics.","PeriodicalId":501612,"journal":{"name":"Antimicrobial Resistance & Infection Control","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141744438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A retrospective pre-post and here-elsewhere study was conducted between January 2014 and June 2020 in 2 adult orthopaedic surgical sites (North and South) of a French university hospital. Decolonisation with Mupirocin and Chlorhexidine was conducted in S. aureus carriers starting February 2017 in the South site (intervention group). Scheduled surgical procedures for hip, knee arthroplasties, and osteosyntheses were included and monitored for one year. The rates of S. aureus SSI in the intervention group were compared to a historical control group (South site) and a North control group. The risk factors for S. aureus SSI were analysed by logistic regression. A total of 5,348 surgical procedures was included, 100 SSI of which 30 monomicrobial S. aureus SSI were identified.

It is important to construct a reliable prediction model for those CRE carriers with high risk of infection. A retrospective cohort study was conducted in two Chinese tertiary hospitals for patients with CRE colonization from 2011 to 2021. Univariable analysis and the Fine-Gray sub-distribution hazard model were utilized to identify potential predictors for CRE-colonized infection, while death was the competing event. A nomogram was established to predict 30-day and 60-day risk of CRE-colonized infection. 879 eligible patients were enrolled in our study and divided into training (n = 761) and validation (n = 118) group, respectively. There were 196 (25.8%) patients suffered from subsequent CRE infection. The median duration of subsequent infection after identification of CRE colonization was 20 (interquartile range [IQR], 14–32) days. Multisite colonization, polymicrobial colonization, catheterization and receiving albumin after colonization, concomitant respiratory diseases, receiving carbapenems and antimicrobial combination therapy before CRE colonization within 90 days were included in final model. Model discrimination and calibration were acceptable for predicting the probability of 60-day CRE-colonized infection in both training (area under the curve [AUC], 74.7) and validation dataset (AUC, 81.1). Decision-curve analysis revealed a significantly better net benefit in current model. Our prediction model is freely available online at https://ken-zheng.shinyapps.io/PredictingModelofCREcolonizedInfection/ . Our nomogram has a good predictive performance and could contribute to early identification of CRE carriers with a high-risk of subsequent infection, although external validation would be required.","PeriodicalId":501612,"journal":{"name":"Antimicrobial Resistance & Infection Control","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140800422","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
