Antimicrobial resistance is increasing; however, antimicrobial drug development is slowing. Now more than ever before, antimicrobial stewardship is of the utmost importance as a way to optimize the use of antimicrobials to prevent the development of resistance and improve patient outcomes. This review describes the why, what, who, how, when, and where of antimicrobial stewardship. Techniques of stewardship are summarized, and a plan for implementation of a stewardship program is outlined.

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.

Within the multicultural and multiracial city of Toronto Ontario, the space of the church is a place for racialized and white Presbyterian women to negotiate convivial hospitality, dignity, and notions of the good life. I use the concept of convivial hospitality to show how conviviality aligns with Christian hospitality when it centres on people’s will for spiritual and physical wellbeing through their relationships and interactions with others. This article focuses on the affective labour involved in the preparation of church community dinners, which were developed and organized by older, racialized Presbyterian women. Meal-time preparations are moments when convivial hospitality emerges among racialized women who pass the time by sharing their food, memories, and life stories, thus affirming a sense of dignity and belonging. Conviviality, however, takes an inhospitable turn when racialized women are subjected to undignified sociality. In exploring times when white Presbyterian women assisted with the community meals, the manner of their help coopted and disenfranchised racialized women from their service to the church and to God. What emerges is convivial inhospitality as racialized churchgoers are subjected to hierarchal interactions, making them feel like outsiders within their own church; yet, in caring for the wellbeing of white congregants to maintain social harmony and congregational unity, they tolerate the status quo which they see as Christian convivial hospitality.

Purpose: The overall goal of the current study was to identify an optimal level and duration of acoustic experience that facilitates language development for pediatric cochlear implant (CI) recipients--specifically, to determine whether there is an optimal duration of hearing aid (HA) use and unaided threshold levels that should be considered before proceeding to bilateral CIs. Method: A total of 117 pediatric CI recipients (ages 5-9 years) were given speech perception and standardized tests of receptive vocabulary and language. The speech perception battery included tests of segmental perception (e.g., word recognition in quiet and noise, and vowels and consonants in quiet) and of suprasegmental perception (e.g., talker and stress discrimination, and emotion identification). Hierarchical regression analyses were used to determine the effects of speech perception on language scores, and the effects of residual hearing level (unaided pure-tone average [PTA]) and duration of HA use on speech perception. Results: A continuum of residual hearing levels and the length of HA use were represented by calculating the unaided PTA of the ear with the longest duration of HA use for each child. All children wore 2 devices: Some wore bimodal devices, while others received their 2nd CI either simultaneously or sequentially, representing a wide range of HA use (0.03-9.05 years). Regression analyses indicate that suprasegmental perception contributes unique variance to receptive language scores and that both segmental and suprasegmental skills each contribute independently to receptive vocabulary scores. Also, analyses revealed an optimal duration of HA use for each of 3 ranges of hearing loss severity (with mean PTAs of 73, 92, and 111 dB HL) that maximizes suprasegmental perception. Conclusions: For children with the most profound losses, early bilateral CIs provide the greatest opportunity for developing good spoken language skills. For those with moderate-to-severe losses, however, a prescribed period of bimodal use may be more advantageous for developing good spoken language skills.

To evaluate the effectiveness of Carolinas Healthcare Outpatient Antimicrobial Stewardship Empowerment Network (CHOSEN), a multicomponent outpatient stewardship program to reduce inappropriate antibiotic prescribing for upper respiratory infections by 20% over 2 years. Before-and-after interrupted time series of antibiotics prescribed between 2 periods: April 2016-October 2017 and May 2018-March 2020. The study included 162 primary-care practices within a large healthcare system in the greater Charlotte, North Carolina region. Adult and pediatric patients with encounters for upper respiratory infections for which an antibiotic is inappropriate. Patient and provider educational materials, along with a web-based provider prescribing dashboard aimed at reducing inappropriate antibiotic prescribing were developed and distributed. Monthly antibiotic prescribing rates were calculated as the number of eligible encounters with an antibiotic prescribed divided by the total number of eligible encounters. A segmented regression analysis compared monthly antibiotic prescribing rates before versus after CHOSEN implementation, while also accounting for practice type and seasonal trends in prescribing. Overall, 286,580 antibiotics were prescribed during 704,248 preintervention encounters and 277,177 during 832,200 intervention encounters. Significant reductions in inappropriate prescribing rates were observed in all outpatient specialties: family medicine (relative difference before and after the intervention, -20.4%), internal medicine (-19.5%), pediatric medicine (-17.2%), and urgent care (-16.6%). A robust multimodal intervention that combined a provider prescribing dashboard with a targeted education campaign demonstrated significant decreases in inappropriate outpatient antibiotic prescribing for upper respiratory tract infections in a large integrated ambulatory network.

Mycobacterium abscessus has emerged as an important cause of lung infection, particularly in patients with bronchiectasis. Innate immune responses must be highly effective at preventing infection with M. abscessus because it is a ubiquitous environmental saprophyte and normal hosts are not commonly infected. M. abscessus exists as either a glycopeptidolipid (GPL) expressing variant (smooth phenotype) in which GPL masks underlying bioactive cell wall lipids, or as a variant lacking GPL which is immunostimulatory and invasive in macrophage infection models. Respiratory epithelium has been increasingly recognized as playing an important role in the innate immune response to pulmonary pathogens. Respiratory epithelial cells express toll-like receptors (TLRs) which mediate the innate immune response to pulmonary pathogens. Both interleukin-8 (IL-8) and human β-defensin 2 (HβD2) are expressed by respiratory epithelial cells in response to toll-like receptor 2 (TLR2) receptor stimulation. In this study, we demonstrate that respiratory epithelial cells respond to M. abscessus variants lacking GPL with expression of IL-8 and HβD2. Furthermore, we demonstrate that this interaction is mediated through TLR2. Conversely, M. abscessus expressing GPL does not stimulate expression of IL-8 or HβD2 by respiratory epithelial cells which is consistent with \"masking\" of underlying bioactive cell wall lipids by GPL. Because GPL-expressing smooth variants are the predominant phenotype existing in the environment, this provides an explanation whereby initial M. abscessus colonization of abnormal lung airways escapes detection by the innate immune system.

Purpose: The aim of this study was to determine whether suprasegmental speech perception contributes unique variance in predictions of reading decoding and comprehension for prelingually deaf children using two devices, at least one of which is a cochlear implant (CI). Method: A total of 104, 5- to 9-year-old CI recipients completed tests of segmental perception (e.g., word recognition in quiet and noise, recognition of vowels and consonants in quiet), suprasegmental perception (e.g., talker and stress discrimination, nonword stress repetition, and emotion identification), and nonverbal intelligence. Two years later, participants completed standardized tests of reading decoding and comprehension. Using regression analyses, the unique contribution of suprasegmental perception to reading skills was determined after controlling for demographic characteristics and segmental perception performance. Results: Standardized reading scores of the CI recipients increased with nonverbal intelligence for both decoding and comprehension. Female gender was associated with higher comprehension scores. After controlling for gender and nonverbal intelligence, segmental perception accounted for approximately 4% and 2% of the variance in decoding and comprehension, respectively. After controlling for nonverbal intelligence, gender, and segmental perception, suprasegmental perception accounted for an extra 4% and 7% unique variance in reading decoding and reading comprehension, respectively. Conclusions: Suprasegmental perception operates independently from segmental perception to facilitate good reading outcomes for these children with CIs. Clinicians and educators should be mindful that early perceptual skills may have long-term benefits for literacy. Research on how to optimize suprasegmental perception, perhaps through hearing-device programming and/or training strategies, is needed.

Although it is important to study the negative outcomes experienced by victims of bullying, it is equally important to study the factors that may buffer victims from distress. Thus, the relationship among social support, victimization, and internalizing-externalizing distress from bullying was investigated. Participants were 355 middle school students who completed the Child and Adolescent Social Support Scale (Malecki, Demaray, & Elliott, 2000) and scales from the Reynolds Bully-Victimization Scales for Schools (Reynolds, 2003). Teacher, classmate, and school support for males and parent support for females moderated the relationship between victimization and internalizing distress from bullying. Close friend support for females moderated the relationship between victimization and externalizing distress from bullying, however, in a direction opposite to that predicted. Results indicate that social support may play a buffering role between victimization and internalizing distress from bullying.

OBJECTIVE To offer antimicrobial stewardship to a long-term acute care hospital using telemedicine. METHODS We conducted an uninterrupted time-series analysis to measure the impact of antimicrobial stewardship on hospital-acquired Clostridium difficile infection (CDI) rates and antimicrobial use. Simple linear regression was used to analyze changes in antimicrobial use; Poisson regression was used to estimate the incidence rate ratio in CDI rates. The preimplementation period was April 1, 2010-March 31, 2011; the postimplementation period was April 1, 2011-March 31, 2014. RESULTS During the preimplementation period, total antimicrobial usage was 266 defined daily doses (DDD)/1,000 patient-days (PD); it rose 4.54 (95% CI, -0.19 to 9.28) per month then significantly decreased from preimplementation to postimplementation (-6.58 DDD/1,000 PD [95% CI, -11.48 to -1.67]; P=.01). The same trend was observed for antibiotics against methicillin-resistant Staphylococcus aureus (-2.97 DDD/1,000 PD per month [95% CI, -5.65 to -0.30]; P=.03). There was a decrease in usage of anti-CDI antibiotics by 50.4 DDD/1,000 PD per month (95% CI, -71.4 to -29.2; P<.001) at program implementation that was maintained afterwards. Anti-Pseudomonas antibiotics increased after implementation (30.6 DDD/1,000 PD per month [95% CI, 4.9-56.3]; P=.02) but with ongoing education this trend reversed. Intervention was associated with a decrease in hospital-acquired CDI (incidence rate ratio, 0.57 [95% CI, 0.35-0.92]; P=.02). CONCLUSION Antimicrobial stewardship using an electronic medical record via remote access led to a significant decrease in antibacterial usage and a decrease in CDI rates.
