Racial/ethnic variation in parent expectations for antibiotics: implications for public health campaigns

Variations in antibiotic prescribing among children enrolled in North Carolina Medicaid, 2013-2019

PURPOSE

The majority of pediatric antibiotic prescribing occurs in the outpatient setting and inappropriate use contributes to antimicrobial resistance. There are regional variations in outpatient antibiotic use with the highest rates occurring in the Southern states, including in Appalachia. The purpose of this study was to describe the rates and risk factors for inappropriate antibiotic prescription among pediatric patients enrolled in North Carolina (NC) Medicaid.

METHODS

We used Medicaid prescription claims data from 2013 to 2019 to describe patterns of pediatric antibiotic prescription in NC. We assessed patient and provider factors to identify variations in prescribing.

FINDINGS

Children who were less than 2 years of age, non-Hispanic White, and living in a rural area had the highest overall rates of antibiotic prescription. Compared to pediatricians, the risk of inappropriate antibiotic prescription was highest among other specialists and general practioners and lowest among nurse practitioners. Rural areas of NC had the highest rates of inappropriate antibiotic prescribing, and the risk for non-Hispanic Black children compared to children of other races/ethnicities was compounded by rurality.

CONCLUSIONS

Prescribing practices in NC differ compared to neighboring states with a lower overall risk of inappropriate prescription in Appalachian regions; however, disparities by race and rurality exist. Outpatient stewardship efforts in NC should focus on ensuring health equity by appreciating racial and geographic variations in prescribing patterns and providing education to all health care providers.

Investigating and Summarizing Information Resources Related to the Clinical Presentation and Diagnosis of Cutaneous Manifestations of Infectious Diseases in Patients With Skin of Color

Patients with skin of color (SOC) present diseases differently in many circumstances, yet there is a lack of information regarding the presentation and diagnosis of cutaneous manifestations in such patients experiencing infectious diseases. Therefore, we conducted a scoping review to investigate and summarize information pertaining to the clinical presentation and diagnosis of cutaneous manifestations of infectious diseases in patients with SOC focusing on the following viral, bacterial, toxin-mediated, and infestation diseases and fungal infections: human immunodeficiency virus, shingles, impetigo, scarlet fever, Lyme disease, toxic shock syndrome, scabies, rickettsioses, and cutaneous fungal infections. This scoping review identified literature gaps regarding cutaneous manifestations of infectious diseases in patients with SOC such as a lack of visual examples and more precise descriptions of common infectious diseases. The lack of better-quality literature and educational resources describing cutaneous manifestations of infectious diseases in patients with SOC may contribute to care barriers; therefore, more research and collaboration are needed in the specialties of both infectious diseases and dermatology.

Demographic and Geographic Inequities in Antimicrobial Use and Prescribing

Little is known about how social determinants of health may impact antimicrobial prescribing among racial and ethnic minority populations, different age groups and genders, and across geographic regions. The factors that influence antimicrobial prescribing are complex, but evidence suggests that demographic and socioeconomic factors do influence prescribing patterns. This review describes the inequities observed in antimicrobial use and prescribing that have been heretofore published, with a focus on differences observed by race and ethnicity, age, gender, and geographic region of the United States.

Socioeconomic differences in antibiotic use for common infections in pediatric urgent-care centers-A quasi-experimental study

OBJECTIVE

To investigate differences in the rate of firstline antibiotic prescribing for common pediatric infections in relation to different socioeconomic statuses and the impact of an antimicrobial stewardship program (ASP) in pediatric urgent-care clinics (PUCs).

DESIGN

Quasi-experimental.

SETTING

Three PUCs within a Midwestern pediatric academic center.

PATIENTS AND PARTICIPANTS

Patients aged >60 days and <18 years with acute otitis media, group A streptococcal pharyngitis, community-acquired pneumonia, urinary tract infection, or skin and soft-tissue infections who received systemic antibiotics between July 2017 and December 2020. We excluded patients who were transferred, admitted, or had a concomitant diagnosis requiring systemic antibiotics.

INTERVENTION

We used national guidelines to determine the appropriateness of antibiotic choice in 2 periods: prior to (July 2017-July 2018) and following ASP implementation (August 2018-December 2020). We used multivariable regression analysis to determine the odds ratios of appropriate firstline agent by age, sex, race and ethnicity, language, and insurance type.

RESULTS

The study included 34,603 encounters. Prior to ASP implementation in August 2018, female patients, Black non-Hispanic children, those >2 years of age, and those who self-paid had higher odds of receiving recommended firstline antibiotics for all diagnoses compared to male patients, children of other races and ethnicities, other ages, and other insurance types, respectively. Although improvements in prescribing occurred after implementation of our ASP, the difference within the socioeconomic subsets persisted.

CONCLUSIONS

We observed socioeconomic differences in firstline antibiotic prescribing for common pediatric infections in the PUCs setting despite implementation of an ASP. Antimicrobial stewardship leaders should consider drivers of these differences when developing improvement initiatives.

Living with polypharmacy: a narrative interview study with older Pakistanis in East London

BACKGROUND

Polypharmacy is a growing and major public health issue. It can be burdensome and risky for patients and costly to healthcare systems. Older adults and those from ethnic minority backgrounds are disproportionately affected by polypharmacy. This study focuses on medication practices among Urdu-speaking Pakistani patients, a significant ethnic group in the UK. Most existing research on medication practices within South-Asian communities centres on adherence, leaving the social and moral dimensions of polypharmacy unpacked. Understanding how British Pakistani patients understand and manage polypharmacy in the context of their daily lives is crucial to avoiding harmful polypharmacy.

METHODS

In-depth narrative interviews were conducted with 15 first-generation Pakistani patients using the Biographical Narrative Interview Method. Participants were recruited from GP practices in East London. All participants were prescribed ten or more regular medications (a pragmatic marker of 'higher risk' polypharmacy) and were aged over 50. Interviews were conducted with a bilingual researcher at home and were designed to elicit narratives of patients' experiences of polypharmacy in the context of their biographies and daily lives.

RESULTS

Polypharmacy is enacted through networks of interpersonal and socio-material relationships. The doctor-patient relationship and the family network held particular significance to study participants. In addition, participants described emotional bonds between themselves and their medicines, identifying them as 'forces for good'-substances which allowed them to maintain their health through the intercession of God. Meanings attributed to medicines and enacted through these social, emotional, and spiritual relationships contributed to emerging and sustaining polypharmacy.

CONCLUSIONS

Patients make sense of and manage treatments in culturally specific ways. Developing an understanding of how medication practices in different communities are enacted is important for informing meaningful and effective conversations with patients about their medicines. Our findings contribute to enabling the integration of culturally sensitive approaches to prescribing.

Health Equity and Antibiotic Prescribing in the United States: A Systematic Scoping Review

We performed a scoping review of articles published from 1 January 2000 to 4 January 2022 to characterize inequities in antibiotic prescribing and use across healthcare settings in the United States to inform antibiotic stewardship interventions and research. We included 34 observational studies, 21 cross-sectional survey studies, 4 intervention studies, and 2 systematic reviews. Most studies (55 of 61 [90%]) described the outpatient setting, 3 articles were from dentistry, 2 were from long-term care, and 1 was from acute care. Differences in antibiotic prescribing were found by patient's race and ethnicity, sex, age, socioeconomic factors, geography, clinician's age and specialty, and healthcare setting, with an emphasis on outpatient settings. Few studies assessed stewardship interventions. Clinicians, antibiotic stewardship experts, and health systems should be aware that prescribing behavior varies according to both clinician- and patient-level markers. Prescribing differences likely represent structural inequities; however, no studies reported underlying drivers of inequities in antibiotic prescribing.

Regional Variation in Outpatient Antibiotic Prescribing for Acute Respiratory Tract Infections in a Commercially Insured Population, United States, 2017

Background

Studies have shown that the Southern United States has higher rates of outpatient antibiotic prescribing rates compared with other regions in the country, but the reasons for this variation are unclear. We aimed to determine whether the regional variability in outpatient antibiotic prescribing for respiratory diagnoses can be explained by differences in prescriber clinical factors found in a commercially insured population.

Methods

We analyzed the 2017 IBM MarketScan Commercial Database of commercially insured individuals aged <65 years. We included visits with acute respiratory tract infection (ARTI) diagnoses from retail clinics, urgent care centers, emergency departments, and physician offices. ARTI diagnoses were categorized based on antibiotic indication. We calculated risk ratios and 95% CIs stratified by ARTI tier and region using log-binomial models controlling for patient age, comorbidities, care setting, prescriber type, and diagnosis.

Results

Of the 14.9 million ARTI visits, 40% received an antibiotic. The South had the highest proportion of visits with an antibiotic prescription (43%), and the West the lowest (34%). ARTI visits in the South are 34% more likely receive an antibiotic for rarely antibiotic-appropriate ARTI visits when compared with the West in multivariable modeling (relative risk, 1.34; 95% CI, 1.33-1.34).

Conclusions

It is likely that higher antibiotic prescribing in the South is in part due to nonclinical factors such as regional differences in clinicians' prescribing habits and patient expectations. There is a need for future studies to define and characterize these factors to better inform regional and local stewardship interventions and achieve greater health equity in antibiotic prescribing.

Coping with in-locus factors and systemic contradictions affecting antibiotic prescription and dispensing practices in primary care-A qualitative One Health study in Brazil

Antimicrobial resistance (AMR) is an increasing threat to global health. The risks and sanitary consequences of AMR are disproportionately experienced by those living in Low- and Middle-Income Countries (LMICs). While addressing antibiotic use has largely been documented in hospital settings, the understanding of social drivers affecting antibiotic prescribing and dispensing practices in the context of human and animal health in primary care (PC) in LMICs remains extremely limited. We seek to explore how in-locus and multi-level social factors influence antibiotic prescriptions and dispensing practices in the context of human and animal health in primary care in Brazil. This is a baseline qualitative One Health study; semi-structured interviews and field observations were undertaken in primary care sites located in a socioeconomically vulnerable area in the city of São Paulo, the most populated city of Brazil. Twenty-five human and animal healthcare professionals (HP) were purposely sampled. Interview data were subject to thematic analysis. Three overlapping social drivers were identified across HPs' discourses: individual and behavioral challenges; relational and contextual factors influencing the overprescription of antibiotics (AB); and structural barriers and systemic contradictions in the health system. As a result of the interaction between multilevel in-locus and structural and contextual factors, HPs experience contextual and territorial challenges that directly influence their risk perception, diagnosis, use of laboratorial and image exams, time and decision to undergo treatment, choice of AB and strategies in coping with AB prescriptions. Additionally, in-locus factors influencing antibiotic prescriptions and dispensing practices are intertwined with individual accounts of risk management, systemic contradictions and ambivalences in the national health system. Our findings suggest interventions tackling AB use and AMR in Brazil should consider the social context, the complex health system structure and current integrated programs and services in PC.

Parents' expectation of antibiotic prescriptions for respiratory infections in children: a systematic review and meta-analysis

Objectives

Despite most childhood infections being self-limiting, children are among the leading consumers of antibiotics. Little is known about parental expectations of antibiotics for childhood infections. A comprehensive systematic review and meta-analysis was conducted to explore the nature and extent of parental expectations of antibiotic prescriptions for children with respiratory infections.

Design

Systematic review and meta-analysis.

Methods

An extensive literature search using six major scientific databases was conducted for all published articles until 7 December 2022. Primary studies reporting parents' expectations of antibiotics for children with upper respiratory tract infections were included after assessment for quality. Heterogeneity between the studies was assessed using the I² statistic and publication bias was analyzed using funnel plots and Egger regression tests. The primary outcome was a summary estimate of the percentage of parents who expect antibiotics from their physicians when their child presents with an upper respiratory tract infection.

Results

From a total of 4510 studies found in the initial searches, a final pool of 19 eligible studies with 15,664 individuals was included in this meta-analysis. Nine of the 19 studies were from the United States or Saudi Arabia. The pooled prevalence of parental expectations of antibiotics in the population reviewed was 55.78% (95% CI = 44.60-66.41). There was significant heterogeneity between the studies, but funnel plot and meta-regression did not detect any publication bias.

Conclusion

More than half of parents expect antibiotics for their children during consultation for upper respiratory tract infections. Such practices may cause undue side effects among children, contribute to the growing burden of antibiotic resistance, and lead to treatment failure for many common infections in the future. To optimize efforts to tackle antimicrobial resistance, shared decision-making and education emphasizing the proper and judicious use of antibiotics are much needed in pediatric healthcare settings. This can also help to manage parents' expectations when seeking antibiotics for their children. Despite pressure from parents, pediatric healthcare providers should continue to advocate for antibiotic use only when warranted and help improve knowledge and awareness amongst parents.

National Disparities in Antibiotic Prescribing by Race, Ethnicity, Age Group, and Sex in United States Ambulatory Care Visits, 2009 to 2016

While efforts have been made in the United States (US) to optimize antimicrobial use, few studies have explored antibiotic prescribing disparities that may drive future interventions. The objective of this study was to evaluate disparities in antibiotic prescribing among US ambulatory care visits by patient subgroups. This was a retrospective, cross-sectional study utilizing the National Ambulatory Medical Care Survey from 2009 to 2016. Antibiotic use was described as antibiotic visits per 1000 total patient visits. The appropriateness of antibiotic prescribing was determined by ICD-9 or ICD-10 codes assigned during the visit. Subgroup analyses were conducted by patient race, ethnicity, age group, and sex. Over 7.0 billion patient visits were included; 11.3% included an antibiotic prescription. Overall and inappropriate antibiotic prescription rates were highest in Black (122.2 and 78.0 per 1000) and Hispanic patients (138.6 and 79.8 per 1000). Additionally, overall antibiotic prescription rates were highest in patients less than 18 years (169.6 per 1000) and female patients (114.1 per 1000), while inappropriate antibiotic prescription rates were highest in patients 18 to 64 years (66.0 per 1000) and in males (64.8 per 1000). In this nationally representative study, antibiotic prescribing disparities were found by patient race, ethnicity, age group, and sex.

Racial and ethnic disparities in outcomes after NICU discharge: An equity-focused model

Significant racial and ethnic disparities exist in birth outcomes and complications related to prematurity. However, little is known about racial and ethnic variations in health outcomes after premature infants are discharged from the neonatal intensive care unit (NICU). We propose a novel, equity-focused conceptual model to guide future evaluations of post-discharge outcomes that centers on a multi-dimensional, comprehensive view of health, which we call thriving. We then apply this model to existing literature on post-discharge inequities, revealing a need for rigorous analysis of drivers and strength-based, longitudinal outcomes.

The vicious cycle of the public's irrational use of antibiotics for upper respiratory tract infections: A mixed methods systematic review

Background

The public's irrational use of antibiotics for upper respiratory tract infections (URTIs) is prevalent worldwide. This study aims to synthesize evidence on how people use antibiotics to treat URTIs, its prevalence and determinants.

Methods

A mixed methods systematic review was conducted using a convergent segregated approach. Relevant studies were searched from PubMed, Cochrane Library, Embase, and Web of Science. A qualitative analysis was initiated, exploring the public's antibiotic use experience for URTIS based on the Consumer Behavior Model (CBM). This was followed by a quantitative synthesis, tapping into the prevalence and predictors of public behavior in antibiotic usage for URTIs. The segregated syntheses complemented each other and were further integrated.

Results

A total of 86 studies were included: 48 quantitative, 30 qualitative, eight mixed methods studies. The included studies were conducted in Europe (n = 29), Asia (n = 27) and North America (n = 21), assessing the behaviors of patients (n = 46), their parents or caregivers (n = 31), or both (n = 9). Eleven themes emerged covering the six CBM stages: need recognition, information searching, alternative evaluation, antibiotic obtaining, antibiotic consumption, and post-consumption evaluation. The six stages reinforce each other, forming a vicious cycle. The high prevalence of the public's irrational use of antibiotics for URTIs is evident despite the high heterogeneity of the studies (ranging from 0.0 to 92.7%). The perceived seriousness of illness and misbelief in antibiotics were identified consistently across the studies as the major motivation driving the public's irrational use of antibiotics for URTIs. However, individual capacity (e.g., knowledge) and opportunity (e.g., contextual restriction) in reducing antibiotic use have mixed effect.

Conclusion

Systemic interventions concerning both supply and demand sides are warranted. The public needs to be educated about the appropriate management of URTIs and health care providers need to re-shape public attitudes toward antibiotic use for URTIs through communication and prescribing practices.

Medications Without Borders: Themes in Caregiver Administration of Imported Medications in Pediatrics

OBJECTIVE

This study aimed to identify motivating factors in why parents administer imported medications to their children.

METHODS

In this qualitative study, we enrolled caregivers of patients younger than 18 years who presented for care at a pediatric emergency department. The study team conducted face-to-face interviews with caregivers in the emergency department and used a semistructured question guide to probe for themes regarding the use of imported medications in children. Interviews were recorded, transcribed, translated if necessary, and coded. We applied grounded theory methodology to assess for themes and adapted the Andersen model of health care utilization to provide a framework for the identified themes.

RESULTS

We completed 30 interviews, 9 of which were conducted in Spanish. Themes surrounding imported medication usage were categorized into predisposing, enabling, and need factors. Predisposing factors included perception that an ill child needs medication to get better, perception of medication quality, and past experiences with medications. Enabling factors included proximity to foreign countries, cost, limited access to primary care, and convenience of obtaining medications. Need factors included utilization of foreign medications for a "simple illness" and utilization of foreign care for a "second opinion."

CONCLUSIONS

Our study used qualitative methodology to gain important insights into the caregiver experience of a diverse patient population. We identify themes not previously published in the medication importation literature. These concepts can provide insights in educational strategies aimed at mitigating the potential dangers of imported medication use in pediatrics.

Providing antibiotics to immigrants: a qualitative study of general practitioners' and pharmacists' experiences

BACKGROUND

If healthcare professionals perceive that patients strongly expect to be prescribed antibiotics, inappropriate prescriptions may result. As it is unknown whether this happens more often with certain patient groups, we explored whether general practitioners (GPs) and pharmacists perceived such expectations when they provided antibiotics to immigrant patients.

METHODS

Ten GPs and five pharmacists from Rotterdam, the Netherlands, were interviewed on the basis of a semi-structured topic guide. Atlas.ti software was then used to conduct a thematic analysis.

RESULTS

GPs felt that immigrant patients, especially those who had arrived recently, were more likely to expect to receive antibiotics than native Dutch patients. However, these expectations had decreased over the last years and did not always lead immigrants to exert pressure on them. Except for language barriers, the factors reported by GPs to influence their antibiotic prescribing behaviour were unrelated to patients' immigrant background. If there was a language barrier, GPs experienced greater diagnostic uncertainty and needed additional time to obtain and communicate correct information. To overcome language barriers, they often used point-of-care testing to convince patients that antibiotics were unnecessary. Although pharmacists rarely experienced problems dispensing antibiotics to immigrants, they and GPs both struggled to find effective ways of overcoming language barriers, and stressed the need for multi-language support materials.

CONCLUSION

While pharmacists rarely experience any problems providing antibiotics to immigrants, GPs regularly face language barriers with immigrant patients, which complicate the diagnostic process and communicating information in the limited available time. This sometimes leads antibiotics to be prescribed inappropriately.

Racial Disparities in Skin Tone Representation of Dermatomyositis Rashes: A Systematic Review

OBJECTIVE

This systemic review assesses skin tone representation in images of dermatomyositis rashes in medical education literature.

METHODS

A review of 59 dermatology, 11 neurology, 10 neuromuscular, 7 rheumatology, and 6 internal medicine textbooks published between 2011 and 2021 and 3 online image databases (UpToDate, VisualDx, and DermNet NZ) that were available through an online medical school library was performed. After extracting images, images with poor lighting or unclear rashes were removed. Authors graded skin tone independently on the Massey and Martin Skin Colour Scale (MMSCS) from 1 (very light) to 10 (very dark). The median score was taken for a final score, grouped within MMSCS 1-2, 3-4, 5-7, or 8-10. Inter-rater reliability was assessed using Kendall's coefficient of concordance (W).

RESULTS

621 images were extracted after reviewing 93 textbooks and 3 online databases. Of the 561 images analyzed, 73.1% of images represented MMSCS 1-2, followed by 3-4 (13.4%), 5-7 (11.8%), and 8-10 (1.8%). Inter-rater reliability was high (W = 0.835). Of the images in MMSCS 5-10, 59.2% were in online databases and 80.6% of textbook images were in dermatology books.

CONCLUSIONS

Patients with lighter skin tones were represented in a higher number of dermatomyositis-related educational materials compared with patients with darker skin tones. Our findings add to current research implicating that darker skin tones are underrepresented in cutaneous educational materials, specifically for dermatomyositis. This leads to the inability to properly characterize skin involvement in dermatomyositis and may lead to inappropriate exclusion from clinical trials due to erroneous skin scoring.

Reducing antibiotic prescribing by enhancing communication of general practitioners with their immigrant patients: protocol for a randomised controlled trial (PARCA study)

INTRODUCTION

Although antibiotic use and antimicrobial resistance in the Netherlands is comparatively low, inappropriate prescription of antibiotics is substantial, mainly for respiratory tract infections (RTIs). General practitioners (GPs) experience pressure from patients with an immigration background to prescribe antibiotics and have difficulty communicating in a culturally sensitive way. Multifaceted interventions including communication skills training for GPs are shown to be most effective in reducing antibiotic prescription. The PARCA study aims to reduce the number of antibiotic prescriptions for RTIs through implementing a culturally sensitive communication intervention for GPs and evaluate it in a randomised controlled trial (RCT).

METHODS AND ANALYSIS

A non-blinded RCT including 58 GPs (29 for each arm). The intervention consists of: (1) An E-learning with 4 modules of 10-15 min each; (2) A face-to-face training session in (intercultural) communication skills including role plays with a training actor and (3) Availability of informative patient-facing materials that use simple words (A2/B1 level) in multiple languages. The primary outcome measure is the number of dispensed antibiotic courses qualifying for RTIs in primary care, per 1000 registered patients. The secondary outcome measure is the number of all dispensed antibiotic courses, per 1000 registered patients. The intervention arm will receive the training in Autumn 2021, followed by an observation period of 6 winter months for which numbers of antibiotics will be collected for both trial arms. The GPs/practices in the control arm can attend the training after the observation period.

ETHICS AND DISSEMINATION

The study protocol was approved by the Medical Ethics Review Committee of Erasmus MC, University Medical Center Rotterdam (MEC-2020-0142). The results of the trial will be published in international peer-reviewed scientific journals and will be disseminated through national and international congresses. The project is funded by The Netherlands Organisation for Health Research and Development (ZonMw).

Going shopping or consulting in medical visits: Caregivers' roles in pediatric antibiotic prescribing in China

Antimicrobial Resistance (AMR) is one of the gravest global public health crises today. Over-prescription in clinical settings is a primary driver. Despite its magnitude and scale, the problem of antibiotic over-prescription in China has not been understood adequately nor addressed effectively. Based on a corpus of 183 video-recorded medical conversations in the Chinese pediatric setting, we show that patient caregivers frequently challenge the physician's medical authority by resisting treatment recommendations, displaying a high level of entitlement to influence the treatment decision. As a result, even when the physicians do not recommend antibiotics based on their professional judgment, they prescribe in response to caregiver pressure. We argue that the relatively low level of medical authority is a significant contributor to the problem. Under this consumerist model of doctor-patient relationship, antibiotics are oriented to by the caregivers as a negotiable commodity and physicians are unable to fulfill their role as gatekeepers. Educational campaigns are needed to promote rational use of antibiotics among patients and caregivers, and serious efforts are called for to protect physicians' professional authority in China.

Native and foreign healthcare workers' knowledge of appropriate use of antibiotics: a prospective pre-post study in Danish nursing homes

Aim:

The aim was to determine the association between healthcare workers’ (HCWs) country of birth and their knowledge of appropriate use of antibiotics, and whether the association changed after an educational intervention.

Background:

Older residents in nursing homes have been recognized to receive excessively antibiotic treatments. HCWs often represent an important link between the older resident and the general practitioner prescribing the antibiotics, thus their knowledge of appropriate use of antibiotics is important.

Methods:

This study was conducted as a prospective pre-post study. Totally, 312 HCWs from 7 nursing homes in Denmark were included. For statistical analyses, χ² test and a linear mixed regression model were applied.

Findings:

Native HCWs were more likely to have a higher percentage of correct responses to single statements related to knowledge of appropriate use of antibiotics. Native HCWs had a significantly higher knowledge-of-antibiotic score compared to foreign HCWs (−7.53, P < 0.01). This association remained significant after adjusting for relevant covariates (−5.64, P < 0.01). Native HCWs’ mean change in knowledge-of-antibiotic score after the intervention did not differ from the foreign HCWs’ mean change in knowledge-of-antibiotic score.

Conclusion:

Our findings indicate that HCWs born outside Denmark reveal a lower knowledge-of-antibiotic score than HCWs born in Denmark despite comparable educational backgrounds. All participants increased their knowledge from baseline to follow-up. Our findings also indicate that an educational seminar cannot equalize the difference in knowledge between native and foreign HCWs. Studies with larger sample size and a more detailed measurement of cultural identity should investigate this association further.

Accounting for variation in and overuse of antibiotics among humans

Worldwide, antibiotic use is increasing, but many infections against which antibiotics are applied are not even caused by bacteria. Over-the-counter and internet sales preclude physician oversight. Regional differences, between and within countries highlight many potential factors influencing antibiotic use. Taking a systems perspective that considers pharmaceutical commodity chains, we examine antibiotic overuse from the vantage point of both sides of the therapeutic relationship. We examine patterns and expectations of practitioners and patients, institutional policies and pressures, the business strategies of pharmaceutical companies and distributors, and cultural drivers of variation. Solutions to improve antibiotic stewardship include practitioners taking greater responsibility for their antibiotic prescribing, increasing the role of caregivers as diagnosticians rather than medicine providers, improving their communication to patients about antibiotic treatment consequences, lessening the economic influences on prescribing, and identifying antibiotic alternatives.

Socioeconomic Status and Determinants of Pediatric Antibiotic Use

Introduction. Evidence suggests that early-life antibiotic use can alter gut microbiome, predisposing children to obesity. The obesity epidemic has a disproportionate effect on individuals from lower socioeconomic status (SES). Thus, this study aims to explore the link between SES and antibiotic use. Design. We performed a retrospective cohort study of all babies born at and receiving 2 or more outpatient visits at a large, suburban health system in Illinois (United States) between 2007 and 2017. We collected data on zip code as a proxy for SES and antibiotic use in the first year of life. We also obtained comorbid diagnosis codes, race/ethnicity, gender, and number of inpatient, outpatient, and emergency department visits. Results. A total of 7224 patients met our study criteria. Children from low-poverty areas received a lifetime average of 4.28 prescriptions, while those from high-poverty neighborhoods received an average of 3.31 prescriptions. This was statistically significant in our unadjusted analysis but not after adjusting for covariates. Children from high-poverty areas were significantly more likely to receive more antibiotics at 48 hours, 1 week, and 1 month of life in our unadjusted analysis, but not after adjusting for covariates. In our unadjusted and adjusted analyses, children from high-poverty areas were significantly more likely to have received antibiotics at 1 week of life. Conclusion. The relationship between SES and antibiotic use warrants further investigation to help elucidate possible causes of the disproportionate impact obesity has in low-income communities.

Reductions in Parent Interest in Receiving Antibiotics following a 90-Second Video Intervention in Outpatient Pediatric Clinics

OBJECTIVES

To assess the impact of a 90-second animated video on parents' interest in receiving an antibiotic for their child.

STUDY DESIGN

This pre-post test study enrolled English and Spanish speaking parents (n = 1051) of children ages 1-5 years presenting with acute respiratory tract infection symptoms. Before meeting with their provider, parents rated their interest in receiving an antibiotic for their child, answered 6 true/false antibiotic knowledge questions, viewed the video, and then rated their antibiotic interest again. Parents rated their interest in receiving an antibiotic using a visual analogue scale ranging from 0 to 100, with 0 being "I definitely do not want an antibiotic," 50 "Neutral," and 100 "I absolutely want an antibiotic."

RESULTS

Parents were 84% female, with a mean age of 32 ± 6.0, 26.0% had a high school education or less, 15% were black, and 19% were Hispanic. After watching the video, parents' average antibiotic interest ratings decreased by 10 points (mean, 57.0 ± 20 to M ± 21; P < .0001). Among parents with the highest initial antibiotic interest ratings (≥60), even greater decreases were observed (83.0 ± 12.0 to 63.4 ± 22; P < .0001) with more than one-half (52%) rating their interest in the low or neutral ranges after watching the video.

CONCLUSIONS

A 90-second video can decrease parents' interest in receiving antibiotics, especially among those with higher baseline interest. This scalable intervention could be used in a variety of settings to reduce parents' interest in receiving antibiotics.

Perceptions of Responsibility for Antibiotic Resistance: Implications for Stewardship Campaigns

Widespread public engagement with antibiotic stewardship is essential to stem the rising incidence of antibiotic-resistant infections; however, campaigns that focus on increasing knowledge have not been effective. Beliefs about who is responsible for causing and solving antibiotic resistance (AR) likely influences engagement in antibiotic stewardship behaviors. This study assesses the U.S. public's AR causal and solution responsibility attributions and the capacity for changing these attributions to inform future antibiotic stewardship campaigns. U.S. participants (N= 1,014) diverse across race, education, and geographic region were surveyed on their beliefs about responsibility for AR for themselves, the general public, healthcare providers, scientists, and drug companies. Substantial percentages of participants held causal and solution beliefs about antibiotic resistance that likely inhibit antibiotic stewardship behaviors. Participants' beliefs that they and the general public are responsible for causing and solving AR were lower than their beliefs that healthcare providers, scientists, and drug companies are responsible. Beliefs about causal responsibility for any given person or group were significantly and positively associated with beliefs about solution responsibility for that same person or group. Responsibility beliefs differed by age, education level, and racial/ethnic background. Results highlight the need for antibiotic stewardship campaigns to incorporate responsibility attribution messaging to motivate stewardship.

Medication Utilization at School Age for Children Born Preterm

We explored medication use by children born preterm at 5-8 years of age. Compared with children born at full term, children born preterm had higher medication use that included most therapeutic classifications. Although asthma and chronic lung disease influenced use, prematurity remained an independent risk factor.

Influencing factors of knowledge, attitude, and practice regarding antibiotic use in children with upper respiratory tract infections in Dubai

INTRODUCTION

The main leading cause of the upper respiratory tract infections (URTIs) is viral infection. However, parental attitudes often lead to inappropriate prescription of antibiotics contributing to development of antibiotic resistance. The aim of this study is to assess parental knowledge, attitude, and practice (KAP) towards the use of antibiotics in Dubai and to reveal the associated factors.

METHOD

Questionnaires were distributed to 500 parents of children who were visiting Al Jalila Children's Specialty Hospital in Dubai.

RESULT

A total of 467 subjects agreed to participate in the study. Family income, educational level, nationality, age of the respondents, and numbers of children were identified as factors that significantly associated with inadequate knowledge, negative attitude, or malpractice.

CONCLUSION

The study has identified key factors associated with misuse of URTI antibiotics and highlights the importance of targeting those groups with intervention programs and campaigns to increase awareness and decrease misconception of antibiotic use.

The Association between Changes in External Environment Caused by Migration and Inappropriate Antibiotic Use Behaviors among Chinese University Students: A Cross-Sectional Study

Objectives: This study aims to explore how changes in external factors caused by migration impact antibiotic use behaviors among Chinese university students in comparison to their peers from host areas and origin areas. Migration status was determined by host universities and origin areas, which were broadly defined as eastern vs. western regions in China. Methods: This study analyzed secondary data from a cross-sectional study conducted in China about the antibiotic use behaviors of university students in 2015. Students were divided into four groups: eastern local students (E-Es), western local students (W-Ws), eastern–western migrant students (E-Ws), and western–eastern migrant students (W-Es). Results: After controlling for gender, grade, major, hometown (rural or urban), and parents’ education, E-Ws reported a significantly higher odds of asking for antibiotics (OR = 2.13; 95% CI = 1.54–3.03; p < 0.001) and taking antibiotics prophylactically (OR = 1.85; 95% CI = 1.32–2.56; p < 0.001) compared with E-Es; W-Es reported a significantly lower odds of asking for antibiotics (OR = 0.56; 95% CI = 0.37–0.83; p < 0.01) and taking antibiotics prophylactically (OR = 0.57; 95% CI = 0.41–0.81; p < 0.01) compared with W-Ws. Discussion: Regional differences likely interacted with students’ migration status in forming different antibiotic use behaviors. Factors including financial incentives and loose regulations of antibiotic over-prescription by health providers and peer influence may contribute to worsened antibiotic use behaviors among E-Ws.

Antibiotic dispensing following pediatric visits in the US emergency departments and outpatient settings from 2006 to 2016

This study measured rates and trends in antibiotic dispensing for emergency department (ED) and outpatient visits by age groups. This retrospective analysis used data from the National Institutes of Health Collaboratory Distributed Research Network. The analysis included children (aged > 3 months to <12 years) and adolescents (aged 12 to <19 years) with or without an antibiotic dispensed within 3 days following visits for infectious diagnoses occurring from 2006 to 2016, with no antibiotic fills 90 days prior. Diagnoses were classified as: 1) respiratory tract infections (RTIs) for which antibiotics are mostly indicated; 2) RTIs for which antibiotics are mostly not indicated; 3) respiratory conditions for which antibiotics are never indicated; 4) infectious conditions beyond RTIs regardless of antibiotic indication. The largest annual decrease in any dispensed antibiotics (5% per year) was seen in ED visits for not indicated RTIs and never indicated respiratory conditions (incidence rate ratio [IRR] 0.95, 95% confidence interval [CI] 0.95-0.96). In outpatient settings, a 2% per year decrease was seen for not indicated RTIs and never indicated respiratory conditions (IRR 0.98, 95% CI 0.98-0.98). Broad-spectrum antibiotics had a 1% per year increase in outpatient settings for mostly indicated RTIs (IRR 1.01, 95% CI 1.01-1.01). Compared with adolescents, broad-spectrum antibiotic dispensing rates and trends were consistently higher for children regardless of diagnosis or care setting. Using national claims data, this real-world analysis found uneven decreases in potentially inappropriate antibiotic dispensing, suggesting the need for antibiotic stewardship interventions to become more common in outpatient settings.

Investigating Understandings of Antibiotics and Antimicrobial Resistance in Diverse Ethnic Communities in Australia: Findings from a Qualitative Study

This paper explores the understandings of antibiotics and antimicrobial resistance (AMR) among ethnically diverse informants in Melbourne, Australia. A total of 31 face-to-face semi-structured qualitative interviews were conducted with a sample of ethnic in-patients who were admitted with an acquired antimicrobial infection in a public hospital (n = 7); five hospital interpreters; and ethnic members of the general community (n = 19) as part of a broader study of lay understandings of AMR. Thematic analysis revealed there was poor understanding of AMR, even among informants being treated for AMR infections. Causes of the increasing incidence of AMR were attributed to: weather fluctuations and climate change; a lack of environmental cleanliness; and the arrival of new migrant groups. Asian informants emphasized the need for humoral balance. Antibiotics were viewed as ‘strong’ medicines that could potentially disrupt this balance and weaken the body. Travel back to countries of origin sometimes involved the use of medical services and informants noted that some community members imported antibiotics from overseas. Most used the internet and social media to source health information. There is a lack of information in their own languages. More attention needs to be given to migrant communities who are vulnerable to the development, transmission and infection with resistant bacteria to inform future interventions.

Physician Compliance With Bronchiolitis Guidelines in Pediatric Emergency Departments

An online survey was administered through the American Academy of Pediatrics (AAP) Section of Emergency Medicine Survey Listserv in Fall, 2017. Overall compliance was measured as never using chest X-rays, viral testing, bronchodilators, or systemic steroids. Practice compliance was measured as never using those modalities in a clinical vignette. Chi-square tests assessed differences in compliance between modalities. t tests assessed differences on agreement with each AAP statement. Multivariate logistic regression determined factors associated with overall compliance. Response rate was 47%. A third (35%) agreed with all 7 AAP statements. There was less compliance with ordering a bronchodilator compared with chest X-ray, viral testing, or systemic steroid. There was no association between compliance and either knowledge or agreement with the guideline. Physicians with institutional bronchiolitis guidelines were more likely to be practice compliant. Few physicians were compliant with the AAP bronchiolitis guideline, with bronchodilator misuse being most pronounced. Institutional bronchiolitis guidelines were associated with physician compliance.

Patient expectation trends on receiving antibiotic prescriptions for respiratory tract infections: A systematic review and meta-regression analysis

BACKGROUND

Despite a variety of programs developed to control inappropriate antibiotic prescribing for viral infections, antibiotics are still prescribed excessively for Respiratory Tract Infections (RTI). The patient's expectation to receive an antibiotic often influences the clinician's decision and can lead to inappropriate antibiotic prescriptions. Our objective was to investigate the changes in patient expectations over time when presenting with symptoms of a respiratory infection.

METHODS

We performed a systematic review of patient's expectation to receive antibiotics for RTIs. Two reviewers independently evaluated the collected studies based on inclusion and exclusion criteria. Our search initially identified 12 070 studies, of which 321 studies were eligible for full text review and 37 articles were selected for final evaluation. Meta-regression analysis was used to evaluate the association between patient expectations and different years. Heterogeneity was evaluated using the Q statistic.

RESULTS

Patient expectations (effect size) were pooled using a random effects model. The effect-equality test showed heterogeneity among studies (Q = 3304.23, df = 40, P < 0.0001, k = 40, τ²  = 0.63). Meta-regression results revealed that there is a significant linear negative relationship (B = -1.8374, P < 0.05) between patient expectation and year of data collection, at the global level. A similar finding is observed for the subset of studies conducted outside United States (U.S.) (B = -1.2411, P < 0.1). However, there is no discernible trend for patient expectation in the U.S. or among children and adult subgroups. Also, no significant differences are observed between the patient expectations when considering different age groups.

CONCLUSION

The trend of patient expectation for receiving antibiotics for RTIs is declining over time on a global level and also outside the U.S.

Determinants of Self-Medication With Antibiotics in European and Anglo-Saxon Countries: A Systematic Review of the Literature

Background: Self-medication with antibiotics, which comes in different forms [e.g., leftover or over-the-counter (OTC) use], contributes to antimicrobial resistance as it often happens in a non-prudent manner. In order to tackle this persistent public health problem, its drivers need to be known. The aim of this study was therefore to identify determinants of self-medication with antibiotics via a systematic literature review. Methods: A comprehensive search on determinants of self-medication with antibiotics in the ambulatory care was conducted in PubMed, Scopus, and Embase for studies published between January 2000 and March 2017. There was no limit on the language nor on the type of study. The search was restricted to European and Anglo-Saxon countries. Pairs of reviewers independently screened the abstracts and full texts and performed a quality assessment. Results: From the initial 664 abstracts, 54 publications that included 44 countries were retrieved of which most identified patient related determinants. Important determinants include storing antibiotics at home, poor access to healthcare, and having the intention to self-medicate. Healthcare professionals contribute to the practice of self-medication when catering for demanding and socially vulnerable patients. Healthcare system related determinants include dispensing antibiotics in whole packages and the lack of enforcement of medicine regulations. For some determinants (e.g., patients' age) contradictory results were found. Conclusion: Self-medication with antibiotics is driven by a variety of determinants on the patient, healthcare professional, and system levels. Policy makers should recognise the complexity of self-medication in order to develop multifaceted interventions that target healthcare professionals and patients simultaneously.

Variation in Outpatient Antibiotic Dispensing for Respiratory Infections in Children by Clinician Specialty and Treatment Setting

BACKGROUND

Antibiotics are commonly prescribed for children with acute respiratory infections (ARIs). This study describes the distribution of ARI diagnoses and specifically quantifies antibiotic dispensing for bronchitis and upper respiratory infection (URI) by treatment setting and specialty.

METHODS

This retrospective, observational cross-sectional study used data from the HealthCore Integrated Research Environment containing claims from 14 commercial health plans for 2012 to 2014. Children (2-17 years) with first-episode ARI were identified by diagnosis of acute otitis media (AOM), sinusitis, pharyngitis, bronchitis or URI with no competing infections or chronic illnesses. Treatment setting was where diagnoses were made: primary care offices, urgent care centers (UCC), retail health clinics (RHCs) or emergency departments. Primary outcome measure was antibiotic prescription fills from pharmacies within 2 days of start of ARI episode.

RESULTS

For URI, the highest proportions in antibiotic dispensing were ordered by office-based or UCC family physicians (28% and 30%, respectively) and office-based or UCC nurse practitioners/physician assistants (30% and 29%, respectively). Across all settings and specialties, there was high proportion of antibiotic dispensing for bronchitis (75%). Overall, 48% of 544,531 children diagnosed with ARI filled antibiotics. Nurse practitioners/physician assistants in RHC made the most diagnoses of AOM (24%) and streptococcal pharyngitis (22%).

CONCLUSIONS

Outreach efforts to decrease antibiotic dispensing for URI can be focused on office-based and UCC family physicians and nurse practitioners/physician assistants. All specialties need widespread interventions to reduce antibiotic dispensing for bronchitis. RHC nurse practitioners/physician assistants can be targeted to reduce high proportion of AOM and streptococcal pharyngitis diagnoses.

Antibiotic prescribing for acute respiratory infections in New York City: A model for collaboration

OBJECTIVE

To assess the status of antibiotic prescribing in the ambulatory setting for adult patients with acute respiratory infections (ARIs) and to identify opportunities and barriers for outpatient antibiotic stewardship programs (ASPs).

DESIGN

Mixed methods including point prevalence using chart reviews, surveys, and collaborative learning.

SETTING

Hospital-owned clinics in the New York City area.Participants/PatientsIn total, 31 hospital-owned clinics from 9 hospitals and health systems participated in the study to assess ARI prescribing practices for patients >18 years old.InterventionsEach clinic performed a survey of current stewardship practices, retrospective chart reviews of prescribing in 30 randomly selected ARI patients from October 2015 to March 2016, and surveys of provider characteristics and knowledge. Clinics participated in collaborative learning with peers and experts in antibiotic stewardship and collected data from June 2016 to August 2016. Sites received data reports by individual clinic, aggregated by hospital, and were compared among participating clinics.

RESULTS

Few sites had outpatient stewardship activities. The retrospective review of 1,004 ARI patients revealed that 37.3% of ARI patients received antibiotics, with significant variation in prescribing practices among sites (17.4%-71.0%; P<.001). Macrolides were the most commonly prescribed antibiotics. Most of the 302 respondents recognized the need for tools to assist in prescribing.

CONCLUSIONS

This collaborative study establishes a baseline assessment of the status of outpatient ASPs in New York City. It provides hospitals, health systems, and individual clinics with specific data to inform their development of stewardship interventions targeting ARIs.

Representations of race and skin tone in medical textbook imagery

Although a large literature has documented racial inequities in health care delivery, there continues to be debate about the potential sources of these inequities. Preliminary research suggests that racial inequities are embedded in the curricular edification of physicians and patients. We investigate this hypothesis by considering whether the race and skin tone depicted in images in textbooks assigned at top medical schools reflects the diversity of the U.S.

POPULATION

We analyzed 4146 images from Atlas of Human Anatomy, Bates' Guide to Physical Examination & History Taking, Clinically Oriented Anatomy, and Gray's Anatomy for Students by coding race (White, Black, and Person of Color) and skin tone (light, medium, and dark) at the textbook, chapter, and topic level. While the textbooks approximate the racial distribution of the U.S. population - 62.5% White, 20.4% Black, and 17.0% Person of Color - the skin tones represented - 74.5% light, 21% medium, and 4.5% dark - overrepresent light skin tone and underrepresent dark skin tone. There is also an absence of skin tone diversity at the chapter and topic level. Even though medical texts often have overall proportional racial representation this is not the case for skin tone. Furthermore, racial minorities are still often absent at the topic level. These omissions may provide one route through which bias enters medical treatment.

Patient, Provider, and Practice Characteristics Associated with Inappropriate Antimicrobial Prescribing in Ambulatory Practices

OBJECTIVE

To reduce inappropriate antimicrobial prescribing across ambulatory care, understanding the patient-, provider-, and practice-level characteristics associated with antibiotic prescribing is essential. In this study, we aimed to elucidate factors associated with inappropriate antimicrobial prescribing across urgent care, family medicine, and pediatric and internal medicine ambulatory practices.

DESIGN, SETTING, AND PARTICIPANTS

Data for this retrospective cohort study were collected from outpatient visits for common upper respiratory conditions that should not require antibiotics. The cohort included 448,990 visits between January 2014 and May 2016. Carolinas HealthCare System urgent care, family medicine, internal medicine and pediatric practices were included across 898 providers and 246 practices.

METHODS

Prescribing rates were reported per 1,000 visits. Indications were defined using the International Classification of Disease, Ninth and Tenth Revisions, Clinical Modification (ICD-9/10-CM) criteria. In multivariable models, the risk of receiving an antibiotic prescription was reported with adjustment for practice, provider, and patient characteristics.

RESULTS

The overall prescribing rate in the study cohort was 407 per 1,000 visits (95% confidence interval [CI], 405–408). After adjustment, adult patients seen by an advanced practice practitioner were 15% more likely to receive an antimicrobial than those seen by a physician provider (incident risk ratio [IRR], 1.15; 95% CI, 1.03–1.29). In the pediatric sample, older providers were 4 times more likely to prescribe an antimicrobial than providers aged ≤30 years (IRR, 4.21; 95% CI, 2.96–5.97).

CONCLUSIONS

Our results suggest that patient, practice, and provider characteristics are associated with inappropriate antimicrobial prescribing. Future research should target antibiotic stewardship programs to specific patient and provider populations to reduce inappropriate prescribing compared to a “one size fits all” approach.

Practice Variation in Acute Bronchiolitis: A Pediatric Emergency Research Networks Study

BACKGROUND AND OBJECTIVES

Studies characterizing hospitalizations in bronchiolitis did not identify patients receiving evidence-based supportive therapies (EBSTs). We aimed to evaluate intersite and internetwork variation in receipt of ≥1 EBSTs during the hospital management of infants diagnosed with bronchiolitis in 38 emergency departments of pediatric emergency research networks in Canada, the United States, Australia, New Zealand, the United Kingdom, Ireland, Spain, and Portugal. We hypothesized that there would be significant variation, adjusted for patient characteristics.

METHODS

Retrospective cohort study of previously healthy infants aged <12 months with bronchiolitis. Our primary outcome was that hospitalization occurred with EBST (ie, parenteral fluids, oxygen, or airway support).

RESULTS

Out of 3725 participants, 1466 (39%) were hospitalized, and 1023 out of 1466 participants (69.8%) received EBST. The use of EBST varied by site (P < .001; range 6%-99%, median 23%), but not by network (P = .2). Significant multivariable predictors and their odds ratios (ORs) were as follows: age (0.9), oxygen saturation (1.3), apnea (3.4), dehydration (3.2), nasal flaring and/or grunting (2.4), poor feeding (2.1), chest retractions (1.9), and respiratory rate (1.2). The use of pharmacotherapy and radiography varied by network and site (P < .001), with respective intersite ranges 2% to 79% and 1.6% to 81%. Compared with Australia and New Zealand, the multivariable OR for the use of pharmacotherapy in Spain and Portugal was 22.7 (95% confidence interval [CI]: 4.5-111), use in Canada was 11.5 (95% CI: 3.7-36), use in the United States was 6.8 (95% CI: 2.3-19.8), and use in the United Kingdom was 1.4 (95% CI: 0.4-4.2). Compared with United Kingdom, OR for radiography use in the United States was 4.9 (95% CI 2.0-12.2), use in Canada was 4.9 (95% CI 1.9-12.6), use in Spain and Portugal was 2.4 (95% CI 0.6-9.8), and use in Australia and New Zealand was 1.8 (95% CI 0.7-4.7).

CONCLUSIONS

More than 30% of infants hospitalized with bronchiolitis received no EBST. The hospital site was a source of variation in all study outcomes, and the network also predicted the use of pharmacotherapy and radiography.

Perceptions and practice of physicians and pharmacists regarding antibiotic misuse at primary health centres in Qatar: A cross-sectional study

Objectives

The inappropriate use of antibiotics is a critical global health issue. The lack of antimicrobial stewardship exposes the community to unwarranted medication and contributes to the development of antimicrobial resistance. This study evaluated the perceptions and practice of physicians and pharmacists at primary healthcare centres of Qatar with respect to antibiotic misuse.

Methods

In this cross-sectional study, we recruited 226 physicians and 82 pharmacists in primary health care centres. A multistage cluster sampling technique was used for data collection. Separate self-administered questionnaires were administered to physicians and pharmacists.

Results

Response rates for physicians and pharmacists were 97.8% and 100%, respectively. Both physicians (90.7%) and pharmacists (87.8%) perceived antibiotic misuse as a major public health issue. To prevent antibiotic misuse, most physicians and pharmacists reported a focus on patient education as well as good practices in their work.

Conclusion

This study provides novel evidence on the perceptions and practices of health professionals concerning antibiotic prescription in primary healthcare settings of Qatar.

Racial and Ethnic Differences in Antibiotic Use for Viral Illness in Emergency Departments

BACKGROUND AND OBJECTIVES

In the primary care setting, there are racial and ethnic differences in antibiotic prescribing for acute respiratory tract infections (ARTIs). Viral ARTIs are commonly diagnosed in the pediatric emergency department (PED), in which racial and ethnic differences in antibiotic prescribing have not been previously reported. We sought to investigate whether patient race and ethnicity was associated with differences in antibiotic prescribing for viral ARTIs in the PED.

METHODS

This is a retrospective cohort study of encounters at 7 PEDs in 2013, in which we used electronic health data from the Pediatric Emergency Care Applied Research Network Registry. Multivariable logistic regression was used to examine the association between patient race and ethnicity and antibiotics administered or prescribed among children discharged from the hospital with viral ARTI. Children with bacterial codiagnoses, chronic disease, or who were immunocompromised were excluded. Covariates included age, sex, insurance, triage level, provider type, emergency department type, and emergency department site.

RESULTS

Of 39 445 PED encounters for viral ARTIs that met inclusion criteria, 2.6% (95% confidence interval [CI] 2.4%-2.8%) received antibiotics, including 4.3% of non-Hispanic (NH) white, 1.9% of NH black, 2.6% of Hispanic, and 2.9% of other NH children. In multivariable analyses, NH black (adjusted odds ratio [aOR] 0.44; CI 0.36-0.53), Hispanic (aOR 0.65; CI 0.53-0.81), and other NH (aOR 0.68; CI 0.52-0.87) children remained less likely to receive antibiotics for viral ARTIs.

CONCLUSIONS

Compared with NH white children, NH black and Hispanic children were less likely to receive antibiotics for viral ARTIs in the PED. Future research should seek to understand why racial and ethnic differences in overprescribing exist, including parental expectations, provider perceptions of parental expectations, and implicit provider bias.

Predictors for under-prescribing antibiotics in children with respiratory infections requiring antibiotics

BACKGROUND/OBJECTIVE

Previous studies showed variability in the use of diagnostic and therapeutic resources for children with febrile acute respiratory tract infections (ARTI), including antibiotics. Unnecessary antibiotic use has important public and individual health outcomes, but missed antibiotic prescribing also has important consequences. We sought to determine factors associated with antibiotic prescribing in pediatric ARTI, specifically those with pneumonia.

METHODS

We assessed national trends in the evaluation and treatment of ARTI for pediatric emergency department (ED) patients by analyzing the National Hospital Ambulatory Medical Care Survey from 2002 to 2013. We identified ED patients aged ≤18 with a reason for visit of ARTI, and created 4 diagnostic categories: pneumonia, ARTI where antibiotics are typically indicated, ARTI where antibiotics are typically not indicated, and "other" diagnoses. Our primary outcome was factors associated with the administration or prescription of antibiotics. A multivariate logistic regression model was fit to identify risk factors for underuse of antibiotics when they were indicated.

RESULTS

We analyzed 6461 visits, of which 10.2% of the population had a final diagnosis of pneumonia and 86% received antibiotics. 41.5% of patients were diagnosed with an ARTI requiring antibiotics, of which 53.8% received antibiotics. 26.6% were diagnosed with ARTI not requiring antibiotics, of which 36.0% received antibiotics. Black race was a predictor for the underuse of antibiotics in ARTIs that require antibiotics (OR: 0.72; 95% CI: 0.58-0.90).

CONCLUSIONS

For pediatric patients presenting to the ED with pneumonia and ARTI requiring antibiotics, we found that black race was an independent predictor of antibiotic underuse.

Questioning Children: Interactional Evidence of Implicit Bias in Medical Interviews

Social psychologists have shown experimentally that implicit race bias can influence an individual's behavior. Implicit bias has been suggested to be more subtle and less subject to cognitive control than more explicit forms of racial prejudice. Little is known about how implicit bias is manifest in naturally occurring social interaction. This study examines the factors associated with physicians selecting children rather than parents to answer questions in pediatric interviews about routine childhood illnesses. Analysis of the data using a Generalized Linear Latent and Mixed Model demonstrates a significant effect of parent race and education on whether physicians select children to answer questions. Black children and Latino children of low-education parents are less likely to be selected to answer questions than their same aged white peers irrespective of education. One way that implicit bias manifests itself in naturally occurring interaction may be through the process of speaker selection during questioning.

What Happens When "Germs Don't Get Killed and They Attack Again and Again": Perceptions of Antimicrobial Resistance in the Context of Diarrheal Disease Treatment Among Laypersons and Health-Care Providers in Karachi, Pakistan

In south Asia, where diarrhea is common and antibiotics are accessible without prescription, antimicrobial resistance is an emerging and serious problem. However, beliefs and behaviors related to antimicrobial resistance are poorly understood. We explored laypersons' and health-care providers' (HCP) awareness and perceptions of antimicrobial resistance in the context of treatment of adult diarrheal disease in Karachi, Pakistan. In-depth, open-ended interviews were conducted with 40 laypersons and 45 HCPs in a lower-middle-class urban neighborhood. Interviews conducted in Urdu were audiotaped, transcribed, translated, and coded using applied thematic analysis. Slightly over half of laypersons and two-thirds of HCPs were aware that antimicrobial medication could lose effectiveness, but misperceptions were common. Laypersons and HCPs often believed that "the body becomes immune" or "bacteria attack more strongly" if medications are taken "improperly." Another prevalent theme was that causes and effects of antimicrobial resistance are limited to the individual taking the antimicrobial medication and to the specific diarrheal episode. Participants often attributed antimicrobial resistance to patient behaviors; HCP behavior was rarely discussed. Less than half of the HCPs were aware of treatment guidelines. To combat antimicrobial resistance in urban Pakistan, a health systems strategy and community-supported outreach campaigns on appropriate antimicrobial use are needed.

Roles of Clinician, Patient, and Community Characteristics in the Management of Pediatric Upper Respiratory Tract Infections

PURPOSE

Prior studies have evaluated factors predictive of inappropriate antibiotic prescription for upper respiratory tract infections (URIs). Community factors, however, have not been examined. The aim of this study was to evaluate the roles of patient, clinician, and community factors in predicting appropriate management of URIs in children.

METHODS

We used a novel database exchange, linking electronic health record data with community statistics, to identify all patients aged 3 months to 18 years in whom URI was diagnosed in the period from 2007 to 2012. We followed the Healthcare Effectiveness Data and Information Set (HEDIS) quality measurement titled "Appropriate treatment for children with upper respiratory infection" to determine the rate of appropriate management of URIs. We then stratified data across individual and community characteristics and used multiple logistic regression modeling to identify variables that independently predicted antibiotic prescription.

RESULTS

Of 20,581 patients, the overall rate for appropriate management for URI was 93.5%. Family medicine clinicians (AOR = 1.5; 95% CI 1.31, 1.71; reference = pediatric clinicians), urgent care clinicians (AOR = 2.23; 95% CI 1.93, 2.57; reference = pediatric clinicians), patients aged 12 to 18 years (AOR = 1.44; 95% CI 1.25, 1.67; reference = age 3 months to 4 years), and patients of white race/ ethnicity (AOR = 1.83; 95% CI 1.41, 2.37; reference = black non-Hispanic) were independently predictive of antibiotic prescription. No community factors were independently predictive of antibiotic prescription.

CONCLUSIONS

Results correlate with prior studies in which non-pediatric clinicians and white race/ethnicity were predictive of antibiotic prescription, while association with older patient age has not been previously reported. Findings illustrate the promise of linking electronic health records with community data to evaluate health care disparities.
