An international inventory of antimicrobial stewardship (AMS) training programmes for AMS teams

A pilot project of expert nurses for the follow-up of complex intravenous antimicrobial treatment

OBJECTIVE

To report a pilot project of expert nurses for outpatient parenteral antimicrobial treatment (OPAT) follow-up.

METHODS

Three nurses with specific training on antibiotics started a state-funded programme including: i) consultations for OPAT follow-up; ii) hotline for satellite hospitals; iii) peer training. Patients' data were prospectively collected. A representative sample of patients and physicians was interviewed to learn about their opinion on the project.

RESULTS

From December 2020 to December 2021, 118 patients (median age 66.5 years [52-75], male-to-female ratio 2.5) were enrolled, for a total of 621 consultations. Patients were mostly on OPAT for bone and joint infections (n = 76, 64 %) and cardiovascular infections (n = 16, 14 %), for a median duration of 29 days [22-57]. Eleven patients (9 %) required unplanned hospital admissions, and three experienced treatment failure. Most patients (21/22) and physicians in charge (10/10) reported a high level of satisfaction.

CONCLUSIONS

Nurses may be important actors for OPAT follow-up.

Effect of educational intervention on nurses' perception and practice of antimicrobial stewardship programs

BACKGROUND

Nurse involvement in antimicrobial stewardship programs is insufficient, which limits the programs' effectiveness. To evaluate the effect of the training programs on nurses' perception and practice of antimicrobial stewardship to embed it in practice.

METHODS

A quasi-experimental study without a control group was conducted on 115 nurses. A specifically validated and designed instrument was utilized to evaluate perception and practice before, after, and 2 months follow-up the training sessions.

RESULTS

The difference between the pre, post, and 2 months follow-up tests was highly significant for the dimensions of knowledge, perception, and practice (P < .01). Also, nurses reported a lack of knowledge, lack of training, high workload as barriers of AMS. Nurses suggested ways to overcome barriers such as physician and manager support, in-service training every 6 months, and saving time for training and education.

CONCLUSIONS

An educational intervention improved perception and practice among nurses related to antimicrobial stewardship and easily embedded it in practice.

Introducing the global antimicrobial stewardship partnership hub (GASPH): creating conditions for successful global partnership collaboration

In 2015, 196 countries formally committed to a Global Action Plan to address antimicrobial resistance (AMR). However, translating policy into practice is not happening at pace and the recent Global Research on AntiMicrobial resistance (GRAM) Project report confirms the burden of AMR is increasing. Despite progress in establishing surveillance data and investment in new antimicrobials, education and training including use of behavioural science approaches to change practice is lagging. To contribute to addressing this, we have invited organizations to join us as founding members of the Global Antimicrobial Stewardship Partnership Hub (GASPH) (https://global-asp-hub.com/). We will work together to share education resources and foster collaboration to meet the needs of learners and of partner organizations working on tackling AMR. Membership is open to all—professional societies, academic institutes, nongovernmental organizations/civil society, philanthropists and commercial partners interested in supporting a multi-stakeholder global antimicrobial stewardship (AMS) education platform and network.

Biomarkers Predicting Tissue Pharmacokinetics of Antimicrobials in Sepsis: A Review

The pathophysiology of sepsis alters drug pharmacokinetics, resulting in inadequate drug exposure and target-site concentration. Suboptimal exposure leads to treatment failure and the development of antimicrobial resistance. Therefore, we seek to optimize antimicrobial therapy in sepsis by selecting the right drug and the correct dosage. A prerequisite for achieving this goal is characterization and understanding of the mechanisms of pharmacokinetic alterations. However, most infections take place not in blood but in different body compartments. Since tissue pharmacokinetic assessment is not feasible in daily practice, we need to tailor antibiotic treatment according to the specific patient’s pathophysiological processes. The complex pathophysiology of sepsis and the ineffectiveness of current targeted therapies suggest that treatments guided by biomarkers predicting target-site concentration could provide a new therapeutic strategy. Inflammation, endothelial and coagulation activation markers, and blood flow parameters might be indicators of impaired tissue distribution. Moreover, hepatic and renal dysfunction biomarkers can predict not only drug metabolism and clearance but also drug distribution. Identification of the right biomarkers can direct drug dosing and provide timely feedback on its effectiveness. Therefore, this might decrease antibiotic resistance and the mortality of critically ill patients. This article fills the literature gap by characterizing patient biomarkers that might be used to predict unbound plasma-to-tissue drug distribution in critically ill patients. Although all biomarkers must be clinically evaluated with the ultimate goal of combining them in a clinically feasible scoring system, we support the concept that the appropriate biomarkers could be used to direct targeted antibiotic dosing.

Antibiotic Stewardship and Therapeutic Drug Monitoring of β-Lactam Antibiotics: Is There a Link? An Opinion Paper

PURPOSE

In critically ill patients, changes in the pharmacokinetics (PK) of β-lactams can lead to significant variations in serum concentrations, with possibly detrimental effects on outcomes. The utilization of individually calculated doses, extended infusion regimen, and therapeutic drug monitoring (TDM)-guided dose adjustments can mitigate the PK changes and help to achieve and attain an individual PK target.

METHODS

We reviewed relevant literature from 2004 to 2021 using 4 search engines (PubMed, Web of Science, Scopus, and Google Scholar). Unpublished clinical data were also examined.

RESULTS

TDM-guided, individualized dosing strategies facilitated PK target attainment and improved patient outcomes. TDM-guided therapy is a core concept of individualized dosing that increases PK target attainment and identifies possible toxic β-lactam concentrations.

CONCLUSIONS

Individualized dosing and TDM facilitate the rational use of β-lactams and are integral for antibiotic stewardship interventions in critical care, affording the optimal exposure of both pathogen and drugs, along with enhanced treatment efficacy and reduced emergence of antimicrobial resistance.

Outcomes of a National, Cross-Sector Antimicrobial Stewardship Training Initiative for Pharmacists in England

(1) Background: Pharmacists play a pivotal role in tackling Antimicrobial resistance through antimicrobial stewardship (AMS) and are well placed to lead behaviour change interventions across the healthcare system; (2) Methods: A cross-sector AMS training initiative for pharmacists was implemented across England, with three cohorts between 2019-2021. Each cohort took part in an introductory workshop, followed- by a workplace-based quality improvement project supported by peer-assisted learning sessions. Completion of training was determined by an end of training assessment after three to four months. Outcome data and learner survey results were collated, anonymised, and analysed by the training provider. (3) Results: In total, 118 pharmacists participated in the introductory workshop, 70% of these subsequently undertook an improvement project, and 48% engaged workplace stakeholders in the process. Interventions were designed by 57% of learners and 18% completed a at least one Plan-Do-Study-Act cycle. Approximately a quarter of learners met the requirements for a Certificate of Completion. Knowledge quiz scores were obtained from 115 learners pre-training and 28 learners post-training. Paired t-tests conducted for 28 learners showed a statistically significant improvement in mean score from 67.7% to 81.1% (p < 0.0001). Sixty-two learner survey responses were received during the training and 21 follow-up survey responses 6 to 12 months post training. Of the 21 responses to the follow-up survey, ongoing quality improvement work and improvement outcomes were reported by nine and six learners, respectively. (4) Conclusions: The delivery of workplace-based training at scale can be challenging, however this study demonstrates that coupling learning with workplace implementation and peer support can promote behaviour change in learners. Further study into the impact of providing pharmacists across sectors and geographies with access to this type of training will help inform ongoing workforce development interventions.

Assessing the impact of the Global Point Prevalence Survey of Antimicrobial Consumption and Resistance (Global-PPS) on hospital antimicrobial stewardship programmes: results of a worldwide survey

BACKGROUND

The Global Point Prevalence Survey of Antimicrobial Consumption and Resistance (Global-PPS) provides a methodology to support hospitals worldwide in collecting antimicrobial use data. We aim to evaluate the impact of the Global-PPS on local antimicrobial stewardship (AMS) programmes and assess health care professionals' educational needs and barriers for implementing AMS.

METHODS

A cross-sectional survey was disseminated within the Global-PPS network. The target audience consisted of hospital healthcare workers, involved in local surveillance of antimicrobial consumption and resistance. This included contacts from hospitals that already participated in the Global-PPS or were planning to do so. The survey contained 24 questions that addressed the hospital's AMS activities, experiences conducting the PPS, as well as the learning needs and barriers for implementing AMS.

RESULTS

A total of 248 hospitals from 74 countries participated in the survey, of which 192 had already conducted the PPS at least once. The survey response rate was estimated at 25%. In 96.9% of these 192 hospitals, Global-PPS participation had led to the identification of problems related to antimicrobial prescribing. In 69.3% at least one of the hospital's AMS components was initiated as a result of Global-PPS findings. The level of AMS implementation varied across regions. Up to 43.1% of all hospitals had a formal antimicrobial stewardship strategy, ranging from 10.8% in Africa to 60.9% in Northern America. Learning needs of hospitals in high-income countries and in low-and middle-income countries were largely similar and included general topics (e.g. 'optimising antibiotic treatment'), but also PPS-related topics (e.g. 'translating PPS results into meaningful interventions'). The main barriers to implementing AMS programmes were a lack of time (52.7%), knowledge on good prescribing practices (42.0%), and dedicated funding (39.9%). Hospitals in LMIC more often reported unavailability of prescribing guidelines, insufficient laboratory capacity and suboptimal use of the available laboratory services.

CONCLUSIONS

Although we observed substantial variation in the level of AMS implementation across regions, the Global-PPS has been very useful in informing stewardship activities in many participating hospitals. More is still to be gained in guiding hospitals to integrate the PPS throughout AMS activities, building on existing structures and processes.
