Nonmodal Clinical Decision Support and Antimicrobial Restriction Effects on Rates of Fluoroquinolone Use in Uncomplicated Infections

Documenting the indication for antimicrobial prescribing: a scoping review

BACKGROUND

Documenting an indication when prescribing antimicrobials is considered best practice; however, a better understanding of the evidence is needed to support broader implementation of this practice.

OBJECTIVES

We performed a scoping review to evaluate antimicrobial indication documentation as it pertains to its implementation, prevalence, accuracy and impact on clinical and utilisation outcomes in all patient populations.

ELIGIBILITY CRITERIA

Published and unpublished literature evaluating the documentation of an indication for antimicrobial prescribing.

SOURCES OF EVIDENCE

A search was conducted in MEDLINE, Embase, CINAHL and International Pharmaceutical Abstracts in addition to a review of the grey literature.

CHARTING AND ANALYSIS

Screening and extraction was performed by two independent reviewers. Studies were categorised inductively and results were presented descriptively.

RESULTS

We identified 123 peer-reviewed articles and grey literature documents for inclusion. Most studies took place in a hospital setting (109, 89%). The median prevalence of antimicrobial indication documentation was 75% (range 4%-100%). Studies evaluating the impact of indication documentation on prescribing and patient outcomes most commonly examined appropriateness and identified a benefit to prescribing or patient outcomes in 17 of 19 studies. Qualitative studies evaluating healthcare worker perspectives (n=10) noted the common barriers and facilitators to this practice.

CONCLUSION

There is growing interest in the importance of documenting an indication when prescribing antimicrobials. While antimicrobial indication documentation is not uniformly implemented, several studies have shown that multipronged approaches can be used to improve this practice. Emerging evidence demonstrates that antimicrobial indication documentation is associated with improved prescribing and patient outcomes both in community and hospital settings. But setting-specific and larger trials are needed to provide a more robust evidence base for this practice.

A Non-Restrictive Approach to Fluoroquinolone Stewardship at Two Community Hospitals

Background

Fluoroquinolones are one of the most prescribed antimicrobials in the United States and have been increasingly used in inpatient and outpatient settings to treat various infectious diseases syndromes. Due to the unwanted collateral effects on antibiotic resistance, poor susceptibility rates among Gram-negative pathogens, and adverse effects, fluoroquinolones are often targeted by hospital antimicrobial stewardship programs to prevent overutilization. This study describes the association of nonrestrictive antimicrobial stewardship interventions at 2 nonacademic community hospitals on levofloxacin utilization, prescribing patterns on alternative antibiotics, and Pseudomonas aeruginosa nonsusceptibility rates to levofloxacin.

Methods

Nonrestrictive antimicrobial stewardship interventions included monitoring and reporting of fluoroquinolone susceptibility trends to physician groups, performing medication use evaluations of levofloxacin accompanied with prescriber detailing, daily prospective audit and feedback, implementation of beta-lactam-based institutional guidelines for empiric therapy in various infectious disease syndromes, review and adjustment of electronic medical record order sets containing fluoroquinolones, and intensive prescriber education. No preauthorization of levofloxacin was used during this study period. Antibiotic utilization data were collected for the time periods of August 2015 through January 2021. Correlation between levofloxacin and other broad-spectrum antibiotc use was investigated as well as the impact on Pseudomonas aeruginosa levofloxacin nonsusceptibility rates.

Results

Both hospitals showed an overall downward trend in the prescribing of levofloxacin during the time period of August 2015 to January 2021. There was a significant negative correlation between monthly ceftriaxone and levofloxacin days of therapy for both hospitals (P < .0001). There was a positive correlation between levofloxacin days of therapy and P aeruginosa nonsusceptibility (P < .02 at both hospitals).

Conclusions

Our results demonstrate that a nonrestrictive approach to fluoroquinolone stewardship interventions had a significant impact on reducing levofloxacin utilization, increasing ceftriaxone utilization, and improving P aeruginosa levofloxacin susceptibility.

Optimizing Hospital Electronic Prescribing Systems: A Systematic Scoping Review

OBJECTIVE

Considerable international investment in hospital electronic prescribing (ePrescribing) systems has been made, but despite this, it is proving difficult for most organizations to realize safety, quality, and efficiency gains in prescribing. The objective of this work was to develop policy-relevant insights into the optimization of hospital ePrescribing systems to maximize the benefits and minimize the risks of these expensive digital health infrastructures.

METHODS

We undertook a systematic scoping review of the literature by searching MEDLINE, Embase, and CINAHL databases. We searched for primary studies reporting on ePrescribing optimization strategies and independently screened and abstracted data until saturation was achieved. Findings were theoretically and thematically synthesized taking a medicine life-cycle perspective, incorporating consultative phases with domain experts.

RESULTS

We identified 23,609 potentially eligible studies from which 1367 satisfied our inclusion criteria. Thematic synthesis was conducted on a data set of 76 studies, of which 48 were based in the United States. Key approaches to optimization included the following: stakeholder engagement, system or process redesign, technological innovations, and education and training packages. Single-component interventions (n = 26) described technological optimization strategies focusing on a single, specific step in the prescribing process. Multicomponent interventions (n = 50) used a combination of optimization strategies, typically targeting multiple steps in the medicines management process.

DISCUSSION

We identified numerous optimization strategies for enhancing the performance of ePrescribing systems. Key considerations for ePrescribing optimization include meaningful stakeholder engagement to reconceptualize the service delivery model and implementing technological innovations with supporting training packages to simultaneously impact on different facets of the medicines management process.

Clinical Decision Support and Implications for the Clinician Burnout Crisis

OBJECTIVES

This survey aimed to review aspects of clinical decision support (CDS) that contribute to burnout and identify key themes for improving the acceptability of CDS to clinicians, with the goal of decreasing said burnout.

METHODS

We performed a survey of relevant articles from 2018-2019 addressing CDS and aspects of clinician burnout from PubMed and Web of Science™. Themes were manually extracted from publications that met inclusion criteria.

RESULTS

Eighty-nine articles met inclusion criteria, including 12 review articles. Review articles were either prescriptive, describing how CDS should work, or analytic, describing how current CDS tools are deployed. The non-review articles largely demonstrated poor relevance and acceptability of current tools, and few studies showed benefits in terms of efficiency or patient outcomes from implemented CDS. Encouragingly, multiple studies highlighted steps that succeeded in improving both acceptability and relevance of CDS.

CONCLUSIONS

CDS can contribute to clinician frustration and burnout. Using the techniques of improving relevance, soliciting feedback, customization, measurement of outcomes and metrics, and iteration, the effects of CDS on burnout can be ameliorated.

[Analysis of current diagnostic and treatment approaches for acute rhinosinusitis according polyclinics data of the outpatient service of Administrative Directorate of the President of the Russian Federation]

Acute rhinosinusitis is one of the most common outpatient diseases. The duration of antibiotic therapy in practice can be a cause of disagreement. The latest European guideline for rhinosinusitis EPOS 2020 does not specify clear terms for antibacterial therapy for acute bacterial rhinosinusitis, which suggests that they are determined by the attending physician based on the rate of regression of clinical manifestations in each specific clinical case.

OBJECTIVE

To analyze the treatment regimens of adult patients with acute rhinosinusitis in the system of the outpatient service of Administrative Directorate of the President of the Russian Federation in Moscow and compare these schemes with guidelines.

MATERIAL AND METHODS

A retrospective analysis of 2267 outpatient disease histories of patients who were on outpatient treatment with a diagnosis of acute rhinosinusitis treated by otorhinolaryngologists from 7 ambulance clinics for the period from January 2016 to May 2018 was performed. Diagnostic methods and treatment regimens of these patients were evaluated.

RESULTS

At the diagnostic stage, X-ray methods were recommended in 87% of cases, and ultrasound examination of the paranasal sinuses was performed in 4% of cases. Elimination and irrigation therapy was prescribed in 88.05% of cases (1996 people), maxillary sinus punctures were performed in 9.82% of cases, the average number of procedures was 2±1.3, treatment by displacement was performed in 31.8% of patients, the average number of procedures was 3±1.2. Antibiotic therapy was recommended in 77.4% of cases (1755 people), penicillin group drugs were prescribed in 41.5% of cases, macrolides in 30.5% of cases, cephalosporins in 20.7% of cases, and fluoroquinolones in 7.3% of cases. Intranasal glucocorticosteroids were submitted by 67.7% of patients (1535 people), mucolytics and mucoregulatory drugs - 41% of patients, decongestants for acute rhinosinusitis were recommended in 60.9% of cases, antihistamines - in 36.8% of cases. An average course of antibacterial therapy was 5.9±1.34 days, the recovery of the patients was observed on the background of complex treatment.

CONCLUSIONS

In general, in the system of the outpatient service of Administrative Directorate of the President of the Russian Federation, diagnostic and therapeutic measures are carried out in accordance with current clinical recommendations. There is a fairly high percentage of prescribing macrolides (30.5%) and fluoroquinolones (7.3%) in starting therapy, which is a violation of the principles of starting antibacterial therapy.

Clinical Decision Support Systems and Their Role in Antibiotic Stewardship: a Systematic Review

PURPOSE OF REVIEW

The purpose of this article is to perform a systematic review over the past 5 years on the role and effectiveness of clinical decision support systems (CDSSs) on antibiotic stewardship.

RECENT FINDINGS

CDDS interventions found a significant impact on multiple outcomes relevant to antibiotic stewardship. There are various types of CDSS implementations, both active and passive (provider initiated). Passive interventions were associated with more significant outcomes; however, both interventions appeared effective. In the reviewed literature, CDSSs were consistently associated with decreasing antibiotic consumption and narrowing the spectrum of antibiotic usage. Generally, guideline adherence was improved with CDSS, although this was not universal. The effect on other outcomes, such as mortality, Clostridiodes difficile infections, length of stay, and cost, inconsistently showed a significant difference. Overall, CDDS implementation has effectively decreased antibiotic consumption and improved guideline adherence across the various types of CDSS. Other positive outcomes were noted in certain settings, but were not universal. When creating a new intervention, it is important to identify the optimal structure and deployment of a CDSS for a specific setting.

Comparison of Antibiotic Dosing Before and After Implementation of an Electronic Order Set

BACKGROUND

To maximize resources, the antimicrobial stewardship program at a pediatric tertiary care hospital made pediatric dosing specific guidance within the electronic health record available to all hospitals within the health system.

OBJECTIVE

The objective of this study was to compare the appropriateness of antibiotic dosing before and after the implementation of an electronic intravenous (IV) antibiotic order set.

METHODS

This was a retrospective cohort study evaluating orders from patients younger than 18 years who received cefepime, piperacillin-tazobactam, tobramycin, or gentamicin at 12 health-system hospitals. Antibiotic dosing regimens and order set use were evaluated in patients who received the specified antibiotics during the 6-month time frame prior to and following electronic order set availability at each hospital.

RESULTS

In the before and after implementation periods, 360 and 387 total antibiotic orders were included, respectively. Most orders were gentamicin (55.8% in the before implementation period and 54.5% in the after implementation period) followed by piperacillin-tazobactam (22.5% in the before period and 22.2% in the after period). Overall, 663 orders were classified as appropriate (88.8%). Appropriateness was similar in the before or after implementation periods (87.8 vs. 89.7%, p = 0.415). There was a significant difference in appropriateness if a blank order versus the electronic IV antibiotic order set was used (82.8 vs. 90.5%; p = 0.024).

CONCLUSION

No difference in antibiotic appropriateness overall was found in the before and after implementation periods. However, when specifically compared with the appropriateness of dosing when blank order forms were used, dosing was more appropriate when electronic antibiotic order sets were used.
