Uncertainty as a critical determinant of antibiotic prescribing in patients with an asthma exacerbation: a qualitative study

The social experience of uncertainty: a qualitative analysis of emergency department care for suspected pneumonia for the design of decision support

BACKGROUND

This study sought to understand the process of clinical decision-making for suspected pneumonia by emergency departments (ED) providers in Veterans Affairs (VA) Medical Centers. The long-term goal of this work is to create clinical decision support tools to reduce unwarranted variation in diagnosis and treatment of suspected pneumonia.

METHODS

Semi-structured qualitative interviews were conducted with 16 ED clinicians from 9 VA facilities demonstrating variation in antibiotic and hospitalization decisions. Interviews of ED providers focused on understanding decision making for provider-selected pneumonia cases and providers' organizational contexts.

RESULTS

Thematic analysis identified four salient themes: i) ED decision-making for suspected pneumonia is a social process; ii) the "diagnosis drives treatment" paradigm is poorly suited to pneumonia decision-making in the ED; iii) The unpredictability of the ED requires deliberate and effortful information management by providers in CAP decision-making; and iv) the emotional stakes and high uncertainty of pneumonia care drive conservative decision making.

CONCLUSIONS

Ensuring CDS reflects the realities of clinical work as a socially organized process with high uncertainty may ultimately improve communication between ED and admitting providers, continuity of care and patient outcomes.

Improving antibiotic prescribing - Recommendations for funding and pricing policies to enhance use of point-of-care tests

Introduction

Diagnostics can contribute to the improved quality of antibiotic prescribing. However, there is potential to enhance the use of point-of-care tests (POCTs) in general practice. This paper presents fit-for-purpose policy recommendations related to funding and pricing for POCTs applied for community-acquired acute respiratory tract infections (CA-ARTIs).

Methods

The development of the recommendations was informed by an analysis of the current status of funding and pricing policy frameworks for CA-ARTI POCTs in European countries, and an identification of barriers and facilitators for their uptake. Draft recommendations were developed and subsequently revised based on written and verbal feedback from meetings with experts.

Results

The proposal includes four recommendations for policy interventions related to funding and three recommendations regarding pricing policies. Two of the funding policy-related recommendations concern physicians' remuneration, and two relate to product-specific reimbursement (public coverage) of the CA-ARTI POCTs. The pricing-related recommendations include a proposal to explore the introduction of price regulation, to pilot subscription-fee procurement models and to enhance more strategic approaches in public procurement of CA-ARTI POCTs.

Conclusions

Optimised pricing and funding policies could make a difference in enhancing uptake of CA-ARTI POCTs. It is crucial for the successful implementation of policies to consider country settings. Additionally, supportive policy action is recommended, including the systematic use of health technology assessment, stakeholder communication, and monitoring and evaluation.

Comparison of two rapid host-response tests for distinguishing bacterial and viral infection in adults with acute respiratory infection

OBJECTIVES

Distinguishing bacterial from viral acute respiratory infection (ARI) is challenging, leading to inappropriate antimicrobial use and antimicrobial resistance. We evaluated the accuracy of two host-response tests to differentiate bacterial and viral infection.

METHODS

This study used patient blood samples previously collected during a randomised controlled trial of adults hospitalised with ARI. The aetiology for each patient was clinically adjudicated. PAXgene blood RNA samples were tested using the TriVerity test (which measures 29 mRNAs) and serum samples were tested using the MeMed BV test (which measures 3 proteins). Diagnostic accuracy was calculated against adjudicated aetiology.

RESULTS

169 patients were tested. Median age was 60 (45-74) years and 152 (90%) received antibiotics. 60 (36%) were adjudicated as bacterial, 54 (32%) as viral, 26 (15%) as viral/bacterial co-infection, and 29 (17%) as non-infected. For bacterial (including bacterial/viral co-infection) versus non-bacterial infection, the TriVerity bacterial score had a Positive Percentage Agreement (PPA) of 81% (95%CI 70-89) and a Negative Percentage Agreement (NPA) of 66% (95%CI 55-79) and the MeMed BV score had a PPA of 96% (95%CI 90-99) and NPA of 34% (95%CI 23-47). The AUROC for the two tests was 0.77 (95%CI 0.70-0.84) and 0.81 (95%CI 0.74-0.87) respectively, p = 0.388.

CONCLUSIONS

Both tests demonstrated similar overall accuracy for distinguishing bacterial infection with the Triverity test missing some bacterial infections and MeMed BV misclassifying most viral infections as bacterial. Prospective impact studies evaluating antibiotic use, safety and cost effectiveness are now required.

Assessment of the appropriateness of antibiotic prescribing in an acute UK hospital using a national audit tool: a single centre retrospective survey

INTRODUCTION

Antibiotic use drives antibiotic resistance. The UK antimicrobial resistance (AMR) strategy aims to reduce antibiotic use. We aimed to quantify excess antibiotic use in a district general hospital in south-west England.

METHODS

Medical patients discharged in August 2020 who had received antibiotics were included. An audit tool of antibiotic prescribing appropriateness was used to collect relevant clinical information regarding each patient case. The appropriateness of antibiotic use was then determined by two infection specialists and excess days of therapy (DOTs) calculated.

RESULTS

647 patients were discharged in August 2020. Of the 1658 antibiotic DOTs for the 184 patients reviewed, 403 (24%) were excess DOTs. The excess antibiotic DOTs were prescribed in 92 patients (50%); 112/403 (27.8%) excess DOTs originated at the initiation of antibiotic therapy (time point A); 184/403 (45.7%) of excess DOTs occurred at the antibiotic review pre-72 hours (time point B); and 107/403 (26.6%) of excess DOTs were due to protracted antibiotic courses (time point C).

CONCLUSION

24% of antibiotic DOTs were deemed unnecessary. The greatest opportunity to reduce antibiotic use safely was the pre-72 hours antibiotic review, which may provide a target for reducing excess antimicrobial therapy in line with the national AMR strategy.

Primary Healthcare Physicians' Insufficient Knowledge Is Associated with Antibiotic Overprescribing for Acute Upper Respiratory Tract Infections in China: A Cross-Sectional Study

OBJECTIVES

Overuse of antibiotics in healthcare remains prevalent and requires urgent attention in China, particularly in primary healthcare (PHC) facilities. This study aimed to describe the patterns of antibiotic prescriptions for acute upper respiratory tract infections (URTIs) in PHC facilities in China and to investigate how PHC physicians' knowledge influences their antibiotic prescribing behavior.

METHODS

A cross-sectional survey linking physician questionnaire responses and their prescription data was conducted in Shaanxi Province, China. The proportions of URTI visits that received at least one antibiotic, combined antibiotics, and broad-spectrum antibiotics were the main outcomes reflecting antibiotic prescribing behavior. Multivariate mixed-effects logistic regressions were applied to analyze the relationship between PHC physicians' knowledge about antibiotics and their antibiotic prescribing behavior.

RESULTS

A total of 108 physicians filled out the questionnaires between February 2021 and July 2021, and a sample of 11,217 URTI visits attended by these physicians from 1 January 2020 to 31 December 2020 were included in the analysis. The overall mean score of our respondents on the knowledge questions was 5.2 (total score of 10). Over sixty percent (61.2%; IQR 50.2-72.1) of the URTI visits received antibiotics. The percentages of URTI visits prescribed with combined and broad-spectrum antibiotics were 7.8% (IQR 2.3-10.2) and 48.3% (IQR 36.7-58.7), respectively. Third-generation cephalosporins were the most frequently used antibiotics. Physicians with lower antibiotic knowledge scores were more inclined to prescribe antibiotics (p < 0.001), combined antibiotics (p = 0.001), and broad-spectrum antibiotics (p < 0.001).

CONCLUSIONS

Physicians' insufficient knowledge was significantly associated with antibiotic overprescribing. Professional training targeting physicians' knowledge of antibiotics is urgently needed to improve the rational use of antibiotics in grassroots healthcare facilities in China.

Evaluating Quality of Care for Patients with Asthma in the Readmission Penalty Era

Rationale: Asthma poses a significant burden for U.S. patients and health systems, yet inpatient care quality is understudied. National chronic obstructive lung disease (COPD) readmission policies may affect inpatient asthma care through hospital responses to these policies because of imprecise diagnosis and identification of patients with COPD and asthma. Objectives: Evaluate inpatient care quality for patients hospitalized with asthma and potential collateral effects of the Medicare COPD Hospital Readmissions Reduction Program (HRRP). Methods: This was a retrospective cohort study of patients aged 18-54 years hospitalized for asthma across 924 U.S. hospitals (Premier Healthcare Database). Results: Care quality for patients with asthma was evaluated before HRRP implementation (n = 20,820; January 2010-September 2014) and after HRRP implementation (n = 26,885; October 2014-December 2018) using adherence to inpatient care guidelines (recommended, nonrecommended, and "ideal care" [all recommended with no nonrecommended care]). Between 2010 and 2018, at least 80% of patients received recommended care annually. Recommended care decreased similarly (rate of 0.02%/mo) after versus before HRRP (P = 0.8). Nonrecommended care decreased more rapidly after HRRP (rate of 0.29%/mo) versus before HRRP (rate of 0.17%/mo; P < 0.001), with changes driven largely by decreased antibiotic prescribing. Ideal care increased more rapidly after HRRP (rate of 0.25%/mo) versus before HRRP (rate of 0.17%/mo; P = 0.02), with changes driven largely by nonrecommended care improvements. Conclusions: Post-HRRP trends suggest asthma care improved with increased rates of guideline concordance in nonrecommended and ideal care. Although federal policies (e.g., HRRP) may have had positive collateral effects, such as with asthma care, parallel care efforts, including antibiotic stewardship, likely contributed to these improvements.

Hungarian general practice paediatricians' antibiotic prescribing behaviour for suspected respiratory tract infections: a qualitative study

OBJECTIVES

Inappropriate antibiotic prescribing is a major cause of antimicrobial resistance (AMR). The aim of this study was to explore paediatric general practitioners' (GP Peds) antibiotic prescription practice in suspected respiratory tract infections (RTIs), using the capability-opportunity-motivation-behaviour framework.

DESIGN

The design is a qualitative study based on individual, semistructured telephone or virtual interviews.

SETTING

Paediatric general practice in Hungary. We applied stratified maximum variation sampling to cover the categories of age, sex and geographical location of participants.

PARTICIPANTS

We interviewed 22 GP Peds. Nine were male and 13 were female: 2 of them were less than 40 years old, 14 were between 40 and 60 years, and 6 were above 60 years. 10 worked in low-antibiotic prescription areas, 5 in areas with medium levels of antibiotic prescription, 3 in high-antibiotic prescription areas, and 4 in and around the capital city.

RESULTS

Study participants had varying antibiotic prescription preferences. Personal experience and physical examination play a central role in GP Peds' diagnostic and treatment practice. Participants emphasised the need to treat children in their entirety, taking their personal medical record, social background and sometimes parents' preferences into account, besides the acute clinical manifestation of RTI. Most respondents were confident they apply the most effective therapy even if, in some cases, this meant prescribing medicines with a higher chance of contributing to the development of AMR. Some participants felt antibiotic prescription frequency has decreased in recent years.

CONCLUSIONS

Our findings suggest that a more prudent attitude toward antibiotic prescribing may have become more common but also highlight relevant gaps in both physicians' and public knowledge of antibiotics and AMR. To reinforce awareness and close remaining gaps, Hungary should adopt its national AMR National Action Plan and further increase its efforts towards active professional communication and feedback for primary care physicians.

Optimizing Antimicrobial Stewardship in the Emergency Department

Antibiotic stewardship is a core component of emergency department (ED) practice and impacts patient safety, clinical outcomes, and public health. The unique characteristics of ED practice, including crowding, time pressure, and diagnostic uncertainty, need to be considered when implementing antibiotic stewardship interventions in this setting. Rapid advances in pathogen detection and host response biomarkers promise to revolutionize the diagnosis of infectious diseases in the ED, but such tests are not yet considered standard of care. Presently, clinical decision support embedded in the electronic health record and pharmacist-led interventions are the most effective ways to improve antibiotic prescribing in the ED.

A survey study on antibiotic prescription practices for acute asthma exacerbations: An European academy of allergy and clinical immunology task force report

INTRODUCTION

Guidelines recommend treating asthma exacerbations (AAEs) with bronchodilators combined with inhaled and/or systemic corticosteroids. Indications for antibiotic prescriptions for AAEs are usually not incorporated although the literature shows antibiotics are frequently prescribed.

AIM

To investigate the antibiotic prescription rates in AAEs and explore the possible determining factors of those practices.

METHODS

A digital survey was created to determine the antibiotic prescription rates in AAEs and the influencing factors for the prescription practices. The survey was distributed among European academy of allergy and clinical immunology (EAACI) members by mass emailing and through regional/national societies in the Netherlands, Italy, Greece, and Poland. Furthermore, we retrieved local antibiotic prescription rates.

RESULTS

In total, 252 participants completed the survey. Respondents stated that there is a lack of guidelines to prescribe antibiotics in AAEs. The median antibiotic prescription rate in this study was 19% [IQR: 0%-40%] and was significantly different between 4 professions: paediatrics 0% [IQR: 0%-37%], pulmonologists 25% [IQR: 10%-50%], general practitioners 25% [IQR: 0%-50%], and allergologists 17% [IQR: 0%-33%]) (p = 0.046). Additional diagnostic tests were performed in 71.4% of patients before prescription and the most common antibiotic classes prescribed were macrolides (46.0%) and penicillin (42.9%). Important clinical factors for health care providers to prescribe antibiotics were colorised/purulent sputum, abnormal lung sounds during auscultation, fever, and presence of comorbidities.

CONCLUSION

In 19% of patients with AAEs, antibiotics were prescribed in various classes with a broad range among different subspecialities. This study stresses the urgency to compose evidence-based guidelines to aim for more rational antibiotic prescriptions for AAE.

Uncovering influential factors in human antibiotic prescribing: a meta-synthesis study informed by the Theoretical Domains Framework

This study aimed to identify modifiable determinants (facilitators and barriers) related to the choice of prescribing antibiotics in human medicine across clinical settings. Enhanced management of antibiotics can help slow the spread of resistant bacteria. A qualitative meta-synthesis approach was used, according to Sandelowski and Barroso's method. Included studies were evaluated using the Critical Appraisal Skills Programme. Findings were extracted and organized to form a qualitative meta-summary. The Theoretical Domains Framework, the Capabilities-Opportunities-Motivation (COM-B) model and the Behaviour Change Wheel were used as a coding matrix for data interpretation. The analysis of 63 included studies revealed barriers and facilitators in 12 of 14 domains specified by the Theoretical Domains Framework. Prescribers' capabilities, motivation and opportunities were found to be the main drivers of antibiotic prescribing behaviour. Knowledge, skills, beliefs, expectations, the influence of patients and colleagues, organizational culture and infrastructure characteristics have a significant impact on prescribing behaviours. A comprehensive inventory of factors related to antibiotic prescribing has been compiled. Interventions to promote appropriate antibiotic prescribing should take a systemic approach rather than focusing solely on individual-level variables. Furthermore, the adoption of co-design approaches for such interventions is desirable to ensure greater applicability and sustainability in the real-world context of organizations.

Antimicrobial Prescription Behavior in Equine Asthma Cases: An International Survey

Equine asthma is considered a non-infectious respiratory disease characterized by inflammation and hypersensitivity. Given the importance of antimicrobial stewardship, an international survey was designed to investigate the use of antimicrobials in asthmatic horses and the factors influencing prescription behavior. An online survey was distributed in six languages by international mailing lists and social media from December 2020 to January 2022. Of the 434 responses recorded, 249 veterinarians working in 25 countries finished the survey. These included 79 ECEIM/ACVIM diplomats. A total of 204 respondents confirmed national regulations concerning antimicrobial use in their country. Knowledge of the asthma definitions as presented in the revised ACVIM consensus statement was greater in veterinarians treating over 95% of equine patients compared to veterinarians treating more species, based on 10 questions (answers consistent with the consensus statement in 7 (IQR 5-9) and 4 (IQR 3-6) questions, respectively, (p < 0.001)). A total of 131 respondents stated to use antimicrobials (at least 'sometimes') in at least one of the three presented cases consistent with equine asthma. Trimethoprim-Sulfa combinations, penicillin(s), and tetracyclines were prescribed most (by 105, 53 and 38 veterinarians, respectively). Aminoglycosides, cephalosporins and fluoroquinolones were also selected (22, 15, 9 veterinarians respectively). Tetracyclines and cephalosporins are prescribed more often by veterinarians working without national regulations (p 0.019 and p 0.035, respectively). The most selected factors influencing prescription behavior were: 'tracheal wash culture' (62% of 131 veterinarians using antimicrobials in these cases), 'whether other horses in the barn have similar complaints' (60%), and 'response to other forms of therapy' (53%). In conclusion, insight into prescription behavior is the first step towards minimizing and optimizing antimicrobial use.

What works for and what hinders deimplementation of low-value care in emergency medicine practice? A scoping review

OBJECTIVES

Low-value care can harm patients and healthcare systems. Despite a decade of global endeavours, low value care has persisted. Identification of barriers and enablers is essential for effective deimplementation of low-value care. This scoping review is an evidence summary of barriers, enablers and features of effective interventions for deimplementation of low-value care in emergency medicine practice worldwide.

DESIGN

A mixed-methods scoping review was conducted using the Arksey and O'Malley framework.

DATA SOURCES

Medline, CINAHL, Embase, EMCare, Scopus and grey literature were searched from inception to 5 December 2022.

ELIGIBILITY CRITERIA

Primary studies which employed qualitative, quantitative or mixed-methods approaches to explore deimplementation of low-value care in an EM setting and reported barriers, enablers or interventions were included. Reviews, protocols, perspectives, comments, opinions, editorials, letters to editors, news articles, books, chapters, policies, guidelines and animal studies were excluded. No language limits were applied.

DATA EXTRACTION AND SYNTHESIS

Study selection, data collection and quality assessment were performed by two independent reviewers. Barriers, enablers and interventions were mapped to the domains of the Theoretical Domains Framework. The Mixed Methods Appraisal Tool was used for quality assessment.

RESULTS

The search yielded 167 studies. A majority were quantitative studies (90%, 150/167) that evaluated interventions (86%, 143/167). Limited provider abilities, diagnostic uncertainty, lack of provider insight, time constraints, fear of litigation, and patient expectations were the key barriers. Enablers included leadership commitment, provider engagement, provider training, performance feedback to providers and shared decision-making with patients. Interventions included one or more of the following facets: education, stakeholder engagement, audit and feedback, clinical decision support, nudge, clinical champions and training. Multifaceted interventions were more likely to be effective than single-faceted interventions. Effectiveness of multifaceted interventions was influenced by fidelity of the intervention facets. Use of behavioural change theories such as the Theoretical Domains Framework in the published studies appeared to enhance the effectiveness of interventions to deimplement low-value care.

CONCLUSION

High-fidelity, multifaceted interventions that incorporated education, stakeholder engagement, audit/feedback and clinical decision support, were administered daily and lasted longer than 1 year were most effective in achieving deimplementation of low-value care in emergency departments. This review contributes the best available evidence to date, but further rigorous, theory-informed, qualitative and mixed-methods studies are needed to supplement the growing body of evidence to effectively deimplement low-value care in emergency medicine practice.

Appropriateness of antibiotic prescribing varies by clinical services at United States children's hospitals

OBJECTIVE

To describe patterns of inappropriate antibiotic prescribing at US children's hospitals and how these patterns vary by clinical service.

DESIGN

Serial, cross-sectional study using quarterly surveys.

SETTING

Surveys were completed in quarter 1 2019-quarter 3 2020 across 28 children's hospitals in the United States.

PARTICIPANTS

Patients at children's hospitals with ≥1 antibiotic order at 8:00 a.m. on institution-selected quarterly survey days.

METHODS

Antimicrobial stewardship physicians and pharmacists collected data on antibiotic orders and evaluated appropriateness of prescribing. The primary outcome was percentage of inappropriate antibiotics, stratified by clinical service and antibiotic class. Secondary outcomes included reasons for inappropriate use and association of infectious diseases (ID) consultation with appropriateness.

RESULTS

Of 13,344 orders, 1,847 (13.8%) were inappropriate; 17.5% of patients receiving antibiotics had ≥1 inappropriate order. Pediatric intensive care units (PICU) and hospitalists contributed the most inappropriate orders (n = 384 and n = 314, respectively). Surgical subspecialists had the highest percentage of inappropriate orders (22.5%), and 56.8% of these were for prolonged or unnecessary surgical prophylaxis. ID consultation in the previous 7 days was associated with fewer inappropriate orders (15% vs 10%; P < .001); this association was most pronounced for hospitalist, PICU, and surgical and medical subspecialty services.

CONCLUSIONS

Inappropriate antibiotic use for hospitalized children persists and varies by clinical service. Across 28 children's hospitals, PICUs and hospitalists contributed the most inappropriate antibiotic orders, and surgical subspecialists' orders were most often judged inappropriate. Understanding service-specific prescribing patterns will enable antimicrobial stewardship programs to better design interventions to optimize antibiotic use.

Using theories and frameworks to understand how to reduce low-value healthcare: a scoping review

BACKGROUND

There is recognition that the overuse of procedures, testing, and medications constitutes low-value care which strains the healthcare system and, in some circumstances, can cause unnecessary stress and harm for patients. Initiatives across dozens of countries have raised awareness about the harms of low-value care but have had mixed success and the levels of reductions realized have been modest. Similar to the complex drivers of implementation processes, there is a limited understanding of the individual and social behavioral aspects of de-implementation. While researchers have begun to use theory to elucidate the dynamics of de-implementation, the research remains largely atheoretical. The use of theory supports the understanding of how and why interventions succeed or fail and what key factors predict success. The purpose of this scoping review was to identify and characterize the use of theoretical approaches used to understand and/or explain what influences efforts to reduce low-value care.

METHODS

We conducted a review of MEDLINE, EMBASE, CINAHL, and Scopus databases from inception to June 2021. Building on previous research, 43 key terms were used to search the literature. The database searches identified 1998 unique articles for which titles and abstracts were screened for inclusion; 232 items were selected for full-text review.

RESULTS

Forty-eight studies met the inclusion criteria. Over half of the included articles were published in the last 2 years. The Theoretical Domains Framework (TDF) was the most commonly used determinant framework (n = 22). Of studies that used classic theories, the majority used the Theory of Planned Behavior (n = 6). For implementation theories, Normalization Process Theory and COM-B were used (n = 7). Theories or frameworks were used primarily to identify determinants (n = 37) and inform data analysis (n = 31). Eleven types of low-value care were examined in the included studies, with prescribing practices (e.g., overuse, polypharmacy, and appropriate prescribing) targeted most frequently.

CONCLUSIONS

This scoping review provides a rigorous, comprehensive, and extensive synthesis of theoretical approaches used to understand and/or explain what factors influence efforts to reduce low-value care. The results of this review can provide direction and insight for future primary research to support de-implementation and the reduction of low-value care.
