AimTo identify and map bedside nurses' practice scope and competencies regarding antimicrobial stewardship in acute hospital settings, and develop a competency framework for them.BackgroundAntimicrobial stewardship requires multidisciplinary engagement including nursing. However, bedside nurses' antimicrobial stewardship practice scope and competencies in acute hospital settings remain unclear.DesignScoping review.MethodsUsing a five‐stage framework proposed by Arksey and O'Malley and following the Preferred Reporting Items for Systematic reviews and Meta‐Analyses extension for Scoping Reviews guidelines.ResultsA total of 1422 records were retrieved, and 41 studies were included. In addition to the six practices recommended, this review summarized bedside nurses' contributions to five additional fields as well. Correspondingly, the competencies required by bedside nurses were summarized into eight domains: specialized knowledge, safety medication administration, leadership, education, diagnostic stewardship, infection prevention and control, professional development and professional quality.ConclusionNurses' practice scope overlaps greatly with routine nursing practice in antimicrobial stewardship, confirming the evidence that nurses are ideal partners in antimicrobial stewardship. This review developed a competency framework at both basic and advanced levels. Among them, professional knowledge is the foundation, while professional quality motivates nurses to participate. In addition to competency assessment, it can also be used for training and human resource deployment based on seniority or professional level. This could bridge the knowledge gap and improve the engagement of nurses in heavy workload situations.Relevance to clinical practiceThis practice scope will provide opportunities for nurses to engage in antimicrobial stewardship. Moreover, nursing competencies identified in this field could facilitate the development of competency‐based education interventions, talent assessments, training and recruitment programs.Data resourcesPubMed, EMBASE, Web of Science, CINHAL, PsycINFO, Cochrane Library, ProQuest and Scopus were searched from inception to November 2022, with an updated search in March 2023.ImpactThis scoping review provides evidence for best nursing practice scope and competency in antimicrobial stewardship in hospitals. However, it is also in line with the commitment of all nurses in the global community to combat antimicrobial resistance, which has become a global threat. An antimicrobial stewardship competency framework for bedside nurses was developed at both the basic and advanced levels. It would facilitate talent assessment, training, recruitment and human resource management by guiding the development of competency‐based education interventions.Patient or Public ContributionNo Patient or Public Contribution.

Background. Ventilator-associated pneumonia (VAP) is among the most important hospital-acquired infections in an intensive-care unit setting. However, clinical practice lacks effective theoretical tools for preventing VAP in the elderly. Aim. To describe the independent factors associated with VAP in elderly intensive-care unit (ICU) patients on mechanical ventilation (MV) and to construct a risk prediction model. Methods. A total of 1851 elderly patients with MV in ICUs from January 2015 to September 2019 were selected from 12 tertiary hospitals. Study subjects were divided into a model group (n = 1219) and a validation group (n = 632). Two groups of patients were divided into a VAP group and a non-VAP group and compared. Univariate and logistic regression analyses were used to explore influencing factors for VAP in elderly ICU patients with MV, establish a risk prediction model, and draw a nomogram. We used the area under the receiver operating characteristic curve (AUROC) and the Hosmer–Lemeshow goodness-of-fit test to evaluate the predictive effect of the model. Findings regarding the length of ICU stay, surgery, C-reactive protein (CRP), and the number of reintubations were independent risk factors for VAP in elderly ICU patients with MV. Predictive-model verification results showed that the area under the curve (AUC) of VAP risk after MV in the modeling and verification groups was 0.859 and 0.813 ( P < 0.001 ), respectively, while P values for the Hosmer–Lemeshow test in these two groups were 0.365 and 0.485, respectively. Conclusion. The model could effectively predict the occurrence of VAP in elderly patients with MV in ICUs. This study is a retrospective study, so it has not been registered as a clinical study.
