Abstract
Background Fluid overload is associated with poor outcomes, but mitigating its occurrence poses significant challenges. Objective This study sought to assess the impact of hidden fluid volume on fluid overload. Methods This study was a multi-center, retrospective evaluation of adults admitted to a medical or surgical intensive care unit for at least 72 h. Patients were divided into tertiles (low, moderate, and high) based on the hidden fluid volume received. Hidden fluids were defined as intravenous medications, line flushes, blood products, and enteral nutrition. The primary outcome was the incidence of fluid overload at intensive care unit (day 3). Secondary outcomes included mechanical-ventilation free days and association of hidden fluid volume with fluid overload, length of stay, and mortality. Results A total of 219 (73 per tertile) were included, with hidden fluid volume comprising ⩽2500, 2501-4400, and >4400 mL in the low, moderate, and high tertiles, respectively. Incidence of fluid overload was significantly different across groups (low: 3%, moderate: 14%, high: 25%; p < 0.001). No difference existed in mechanical-ventilation free days or in-hospital mortality across tertiles. In binary logistic regression, hidden fluid volume received at 3 days was independently associated with fluid overload (odds ratio = 1.40, 95% confidence interval = 1.15-1.70). Conclusion The volume of hidden fluid volume administered by intensive care unit day 3 independently predicted development of fluid overload.

Abstract
Rapid adoption and widespread use of point-of-care ultrasound (POCUS) has impacted diagnostic testing and clinical care across medical disciplines. The benefits of POCUS must be weighed against certain pitfalls, such as the risk of misdiagnosis and false assurance. Beyond technical error in image acquisition and interpretation, an important pitfall is reliance on POCUS results without considering pre-test patient characteristics or the diagnostic accuracy of POCUS in varying clinical contexts. In this article, we introduce the concept of POCUS stewardship that emphasizes critical evaluation of clinical indications prior to performing POCUS as well as the individual patient and test characteristics of POCUS when integrating results into clinical decisionmaking. Adherence to these principles can lead to optimized POCUS application and improved patient care.

Thabit AK, Shea KM, Guzman OE, Garey KW. Antibiotic utilization within 18 community hospitals in the United States: A 5-year analysis. Pharmacoepidemiol Drug Saf 2020; 30:403-408. [PMID: 33094502 DOI: 10.1002/pds.5156] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2020] [Revised: 10/12/2020] [Accepted: 10/18/2020] [Indexed: 12/19/2022]
Abstract
BACKGROUND Antibiotic overuse is associated with antibiotic resistance. We evaluated antibiotic utilization defined by days of therapy/1000 patient days (DOT/1000 PD) in various community hospitals across the United States. METHODS Community hospitals within the Cardinal Health Drug Cost Opportunity Analytics database were evaluated for the availability of DOT/1000 PD data between 2012 to 2016 for overall and specific antibiotic use and the following classes: narrow-spectrum β-lactams (ampicillin, nafcillin, oxacillin, cefazolin, and cephalexin), non-carbapenem antipseudomonal β-lactams (piperacillin/tazobactam, ceftazidime, and cefepime), carbapenems, anti-methicillin-resistant Staphylococcus aureus agents (vancomycin, linezolid, daptomycin, and tigecycline), and fluoroquinolones. Antibiotic utilization and change in utilization during the study period was calculated using linear regression (β coefficient). RESULTS Eighteen hospitals had antibiotic utilization data available. Hospitals were primarily urban (72%) with an average of 209 total beds and 22 intensive care unit beds. Mean number of pharmacists in these hospitals was nine with a mean pharmacist: bed ratio of 0.05. While all hospitals had antimicrobial stewardship programs established during the study period, only 78% and 22% had infectious diseases (ID) physician and ID pharmacist on staff, respectively. A decrease in antipseudomonal β-lactams (excluding carbapenems) and fluoroquinolones was observed (β coefficients = -1.2 and -2.6, respectively), all other antibiotic classes had increased utilization. CONCLUSION Overall antibiotic utilization increased over 5 years. The increase in narrow-spectrum β-lactams utilization along with the reduction in the use of antipseudomonal β-lactams and fluoroquinolones indicate appropriate antimicrobial stewardship. Institutional antibiotic utilization should be evaluated for appropriateness to limit the overuse of broad-spectrum antibiotics in an effort to reduce resistance development.

Abstract
Rapid molecular diagnostic assays are increasingly used to guide effective antimicrobial therapy. Data on their effectiveness to decrease antimicrobial use in children have been limited and varied. We aimed to assess the impact of the implementation of the FilmArray Meningitis Encephalitis Panel (MEP) on antimicrobial use and outcomes in children. In an observational retrospective study performed at Atlantic Health System (NJ), we sought to evaluate the duration of intravenous antibiotic treatment (days of therapy (DoT)) for patients <21 years of age hospitalized and evaluated for presumptive meningitis or encephalitis before and after the introduction of the MEP. A secondary analysis was performed to determine if recovery of a respiratory pathogen influenced DoT. The median duration of antibiotic therapy prior to the implementation of the MEP was 5 DoT (interquartile range (IQR): 3-6) versus 3 DoT (IQR: 1-5) (p < 0.001) when MEP was performed. The impact was greatest on intravenous third-generation cephalosporin and ampicillin use. We found a reduction in the number of inpatient days associated with the MEP. In the regression analysis, a positive respiratory pathogen panel (RPP) was not a significant predictor of DoT (p = 0.08). Furthermore, we found no significant difference between DoT among patients with negative and positive RPP (p = 0.12). Our study supports the implementation of rapid diagnostics to decrease the utilization of antibiotic therapy among pediatric patients admitted with concerns related to meningitis or encephalitis.

Abstract
Antimicrobial Resistance (AMR) is an ongoing threat to modern medicine throughout the world. The World Health Organisation has emphasized the importance of adequate and effective training of medical students in wise prescribing of antibiotics Furthermore, Antimicrobial Stewardship (AMS) has been recognized as a rapidly growing field in medicine that sets a goal of rational use of antibiotics in terms of dosing, duration of therapy and route of administration. We undertook the current review to systematically summarize and present the published data on the knowledge, attitudes and perceptions of medical students on AMS. We reviewed all studies published in English from 2007 to 2020. We found that although medical students recognize the problem of AMR, they lack basic knowledge regarding AMR. Incorporating novel and effective training methods on all aspects of AMS and AMR in the Medical Curricula worldwide is of paramount importance.

Abstract
Antimicrobial resistance (AMR) is a global concern as it poses a serious threat to our capacity to treat common infectious diseases. Canada has been engaged in actions to address the AMR challenge since 1997, and these actions include a four-pillar national strategy: surveillance; stewardship; infection prevention and control; and research and innovation. Dentists play a significant role in contributing to the efforts around these four-pillars, especially that of stewardship. Studies show that antibiotic prescriptions for oral health reasons, are increasing over time, and 60% to 80% of antibiotics prescribed in a dental setting are not necessarily clinically indicated. The development, promotion and implementation of initiatives to promote optimal use of antimicrobials across Canada will require collaboration among many stakeholders, including the oral health community. Antimicrobial resistance and antimicrobial stewardship are already being discussed within the dental profession in Canada; however, there is still more work to be done in a variety of areas including, but not limited to, dentists' access to and use of current evidence-based guidelines and prescribing protocols enforced by their governing bodies to ensure appropriate prescribing of antibiotics when necessary, and timely and affordable access to oral health care services by Canadians.

Assessment of Testing and Treatment of Asymptomatic Bacteriuria Initiated in the Emergency Department. Open Forum Infect Dis 2020; 7:ofaa537. [PMID: 33324723 PMCID: PMC7724506 DOI: 10.1093/ofid/ofaa537] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2020] [Accepted: 10/29/2020] [Indexed: 02/04/2023] Open
Abstract
Background Reducing antibiotic use in patients with asymptomatic bacteriuria (ASB) has been inpatient focused. However, testing and treatment is often started in the emergency department (ED). Thus, for hospitalized patients with ASB, we sought to identify patterns of testing and treatment initiated by emergency medicine (EM) clinicians and the association of treatment with outcomes. Methods We conducted a 43-hospital, cohort study of adults admitted through the ED with ASB (February 2018-February 2020). Using generalized estimating equation models, we assessed for (1) factors associated with antibiotic treatment by EM clinicians and, after inverse probability of treatment weighting, (2) the effect of treatment on outcomes. Results Of 2461 patients with ASB, 74.4% (N = 1830) received antibiotics. The EM clinicians ordered urine cultures in 80.0% (N = 1970) of patients and initiated treatment in 68.5% (1253 of 1830). Predictors of EM clinician treatment of ASB versus no treatment included dementia, spinal cord injury, incontinence, urinary catheter, altered mental status, leukocytosis, and abnormal urinalysis. Once initiated by EM clinicians, 79% (993 of 1253) of patients remained on antibiotics for at least 3 days. Antibiotic treatment was associated with a longer length of hospitalization (mean 5.1 vs 4.2 days; relative risk = 1.16; 95% confidence interval, 1.08-1.23) and Clostridioides difficile infection (CDI) (0.9% [N = 11] vs 0% [N = 0]; P = .02). Conclusions Among hospitalized patients ultimately diagnosed with ASB, EM clinicians commonly initiated testing and treatment; most antibiotics were continued by inpatient clinicians. Antibiotic treatment was not associated with improved outcomes, whereas it was associated with prolonged hospitalization and CDI. For best impact, stewardship interventions must expand to the ED.

Abstract
Data on antimicrobial use were collected for the 2016 and 2017 calendar years from swine producers in the United States. Nine large systems, collectively producing over 20 million market pigs annually, voluntarily provided data to advance understanding of antimicrobial use in the industry and to support antimicrobial stewardship initiatives. The scope of the study was limited to growing pigs, and the granularity of data varied across the systems. Data were summarized both qualitatively and quantitatively by antimicrobial class, active ingredient and route of administration (injection, water and feed). Data on the purpose of administration, doses and durations of administration were not available, but some information was provided by the responsible veterinarians. Aggregate data were similar both qualitatively and quantitatively in 2016 and 2017, although marked changes between years were evident within systems for some antimicrobials. Antimicrobial use (by weight) was dominated by the tetracycline class (approximately 60% of total use). Antimicrobials in classes categorized as critically important constituted 4.5% and 5.3% of total use in 2016 and 2017, respectively. In both years, fluoroquinolone (0.23%, 0.46%) and 3rd generation cephalosporin (0.15%, 0.11%) use collectively accounted for <1% of total use. Administration was predominantly oral in feed and water, and injection comprised approximately 2% of use overall, but around 12% for critically important antimicrobials. There was considerable variability among systems in patterns of antimicrobial use. This pilot project demonstrates the feasibility of acquiring antimicrobial use data via voluntary sharing. It is currently being expanded among larger swine production systems, and further efforts to enable confidential data sharing and benchmarking for smaller producers are being pursued by the swine industry. Recognized biases in the data caution against over-interpretation of these data as an index of national use.

Abstract
Background The novel severe acute respiratory coronavirus 2 (SARS-CoV-2) that causes coronavirus disease 2019 (COVID-19) originated in December 2019 and has now infected almost 5 million people in the United States. In the spring of 2020, private laboratories and some hospitals began antibody testing despite limited evidence-based guidance. Methods We conducted a retrospective chart review of patients who received SARS-CoV-2 antibody testing from May 14, 2020, to June 15, 2020, at a large academic medical center, 1 of the first in the United States to provide antibody testing capability to individual clinicians in order to identify clinician-described indications for antibody testing compared with current expert-based guidance from the Infectious Diseases Society of America (IDSA) and the Centers for Disease Control and Prevention (CDC). Results Of 444 individual antibody test results, the 2 most commonly described testing indications, apart from public health epidemiology studies (n = 223), were for patients with a now resolved COVID-19-compatible illness (n = 105) with no previous molecular testing and for asymptomatic patients believed to have had a past exposure to a person with COVID-19-compatible illness (n = 60). The rate of positive SARS-CoV-2 antibody testing among those indications consistent with current IDSA and CDC guidance was 17% compared with 5% (P < .0001) among those indications inconsistent with such guidance. Testing inconsistent with current expert-based guidance accounted for almost half of testing costs. Conclusions Our findings demonstrate a dissociation between clinician-described indications for testing and expert-based guidance and a significantly different rate of positive testing between these 2 groups. Clinical curiosity and patient preference appear to have played a significant role in testing decisions and substantially contributed to testing costs.

Abstract
Delayed antibiotic prescription in primary care has been shown to reduce antibiotic consumption, without increasing risk of complications, yet is not widely used in the UK. We sought to quantify the relative importance of factors affecting the decision to give a delayed prescription, using a stated-choice survey among UK general practitioners. Respondents were asked whether they would provide a delayed or immediate prescription in fifteen hypothetical consultations, described by eight attributes. They were also asked if they would prefer not to prescribe antibiotics. The most important determinants of choice between immediate and delayed prescription were symptoms, duration of illness, and the presence of multiple comorbidities. Respondents were more likely to choose a delayed prescription if the patient preferred not to have antibiotics, but consultation length had little effect. When given the option, respondents chose not to prescribe antibiotics in 51% of cases, with delayed prescription chosen in 21%. Clinical features remained important. Patient preference did not affect the decision to give no antibiotics. We suggest that broader dissemination of the clinical evidence supporting use of delayed prescription for specific presentations may help increase appropriate use. Establishing patient preferences regarding antibiotics may help to overcome concerns about patient acceptance. Increasing consultation length appears unlikely to affect the use of delayed prescription.

Abstract
BACKGROUND Prior studies have found that outpatient antibiotics are commonly prescribed for non-bacterial conditions. It is unclear if national prescribing has changed in recent years given recent public health and antimicrobial stewardship initiatives. This study aimed to describe antibiotic prescribing in United States (U.S.) physician offices. MATERIALS/METHODS This was a cross-sectional study of all sampled patient visits in the Centers for Disease Control and Prevention's National Ambulatory Medical Care Survey from 2009 to 2016. Antibiotic use was defined as at least one oral antibiotic prescription during the visit as identified by Multum code(s). Patient visits were categorized by U.S. geographic region and season. ICD-9-CM and ICD-10 codes were used to assess diagnoses and categorize antibiotic use as appropriate, possibly appropriate, or inappropriate. RESULTS Seven billion visits were included for analysis, with 793,415,182 (11.3%) including an antibiotic. Prescribing rates were relatively stable over the study period (102.9-124.9 prescriptions per 1000 visits); however, 2016 had one of the lowest prescribing rates (107.7 per 1000 visits). The most commonly prescribed antibiotic class was macrolides (25 per 1000 visits). The South region and winter season had the highest antibiotic prescribing (118.2 and 129.7 per 1000 visits, respectively). Of patients who received an antibiotic, 55.9%, 35.7%, and 8.4% were classified as inappropriate, possibly appropriate, and appropriate, respectively. The most common conditions in which antibiotics were prescribed inappropriately included those with no indication in any of the predefined diagnosis codes (40.1%), other skin conditions (17.3%), and viral upper respiratory conditions (13.3%). CONCLUSIONS There was no significant reduction in outpatient antibiotic prescribing rates among U.S. outpatients from 2009 to 2016 and prescribing varied by region and season. These data suggest that more than half of antibiotics were prescribed inappropriately, with the majority of antibiotics prescribed with no indication. However, these findings need to be confirmed with robust prospective studies.

Abstract
OBJECTIVE Procalcitonin (PCT) is a biomarker that may help providers optimize antibiotic (AB) therapy. Numerous clinical trials have demonstrated the utility of PCT-guided decision algorithms in treating lower respiratory tract infections and sepsis, but evidence from real-world studies is limited. This study sought to evaluate the effects of PCT on select clinical outcomes in community hospitals. METHODS An observational, retrospective, case-control study was conducted. Hospitals from a large US hospital system were categorized into "treatment" and "control" hospitals. Treatment hospitals were those with in-house PCT testing, a pharmacy team tasked with PCT testing follow-up and results in the patient's electronic medical records alongside a recommendation on AB treatment. Control hospitals either did not have PCT testing available in house or sent out tests to a laboratory or neighboring facility. Patients from treatment hospitals were matched 1:1 to patients from control hospitals based on admission diagnosis code, sex, age and whether an intensive care unit admission was observed. Clinical outcomes included number of days of AB treatment, length of stay, 30 day readmissions, mortality and acute kidney injury. Comparisons were conducted using multivariable regressions accounting for clustering at the hospital level. RESULTS Patients from treatment hospitals had significantly shorter hospital stays (-0.68 days, 95% CI: -1.26, -0.09; p = .02). A reduction in days of AB treatment (-1.50 days, 95% CI: -3.27, 0.27; p = .10) was observed, but did not reach statistical significance. CONCLUSION These findings suggest that PCT, along with specific treatment recommendations, may lead to shortened hospital stays with no adverse outcome on patient safety.

Abstract
Background Multiple factors have led to an extremely high volume of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reverse transcription polymerase chain reaction (RT-PCR) testing. Concerns exist about sensitivity and false-negative SARS-CoV-2 RT-PCR testing results. We describe a retrospective observational study examining the utility of repeat nasopharyngeal (NP) SARS-CoV-2 RT-PCR testing at an academic center in a low-prevalence setting. Methods All patients within our health system with >1 NP SARS-CoV-2 RT-PCR test result were included. SARS-CoV-2 RT-PCR testing was performed according to 1 of 4 validated assays. Key clinical and demographic data were collected, including whether the patient was inpatient or outpatient at time of the test and whether the test was performed as part of a person under investigation (PUI) for possible coronavirus disease 2019 or for asymptomatic screening. Results A total of 660 patients had >1 NP SARS-CoV-2 PCR test performed. The initial test was negative in 638. There were only 6 negative-to-positive conversions (0.9%). All 6 were outpatients undergoing a PUI workup 5–17 days after an initial negative result. In >260 inpatients with repeat testing, we found no instances of negative-to-positive conversion including those undergoing PUI or asymptomatic evaluation. Conclusions In a low-prevalence area, repeat inpatient testing after an initial negative result, using a highly analytically sensitive SARS-CoV-2 RT-PCR, failed to demonstrate negative-to-positive conversion. The clinical sensitivity of NP RT-PCR testing may be higher than previously believed. These results have helped shape diagnostic stewardship guidelines, in particular guidance to decrease repeated testing in the inpatient setting to optimize test utilization and preserve resources.

Abstract
BACKGROUND Increased recognition of the dangers of opioid analgesia has led to significant focus on strategies for reducing use through multimodal analgesia, enhanced recovery protocols, and standardized guidelines for prescribing. Our institution implemented a standard protocol for prescribing analgesics at discharge after ventral hernia repair (VHR). We hypothesize that this strategy significantly reduces opioid use. METHODS A standardized protocol for discharge prescribing was implemented in March 2018. Patients were prescribed ibuprofen, acetaminophen, and opioids based on milligram morphine equivalent (MME) use the 24 hours prior to discharge. We retrospectively reviewed prescriptions of opioids for two 6-month periods-July-December 2017 (PRE) and July-December 2018 (POST)-for comparison using EPIC report and the South Carolina Prescription Monitoring Program. Analysis performed included Mann-Kendall linear trend test and Student's t-test for continuous variables. RESULTS VHR was performed in 105 patients in the PRE and 75 patients in the POST group. Total MME prescribed decreased significantly from mean 322.7 + 261.3/median 225 (IQR 150-400) MME to 141.6 + 150.4/median 100 (50-184) MME (P < .001). This represents a 57% reduction in mean opioid MME prescriptions. Acetaminophen prescribing increased from 10% to 65%, and ibuprofen from 7.6% to 61.3%. Refills were prescribed in 21 patients (20%) during the PRE period, which decreased to 10.7% during the POST group (P = .141). Implementation of an evidence-based protocol significantly reduces opioid prescribing after VHR. DISCUSSION A multimodal approach to postoperative pain management decreases the need for opioids. The additional implementation of an evidence-based prescribing protocol results in significant reduction of opioid use following VHR.

Abstract
INTRODUCTION International guidelines have recommended for many years to start antimicrobials as early as possible in sepsis and shock. This concept has been challenged by the controversial results of experimental studies and clinical cohorts and resulted in intense debate in the literature. This review aims to summarize the available knowledge on early antimicrobial therapy and to consider perspectives. AREAS COVERED First, after a research using MEDLINE, we reviewed the studies that advocated the implementation of early antimicrobial therapy. We then discussed the drawbacks of these studies. Finally, we suggested possible explanations of the benefit and then absence of the prognostic impact of early antimicrobial therapy i.e. confounding factors, irreversibility of the inflammatory process, non-control of the source of the infection, pharmacodynamic considerations and the harmful effect of antimicrobial drugs. EXPERT OPINION Sepsis is very heterogeneous. The first antimicrobial therapy should be personalized. The sickest patients should be given early antimicrobial therapy, whereas a 'watch and wait process' should be preferred for less severe patients, to allow confirmation of sepsis, identification of pathogens and administration of adequate antimicrobial therapy. We propose steps to personalize the first antimicrobial therapy. New early diagnostic tools will assist the physicians in the future.

Abstract
Background Persons with human immunodeficiency virus (HIV) experience high rates of medication-related errors when admitted to the inpatient setting. Data are lacking on the impact of a combined antiretroviral (ARV) stewardship and transitions of care (TOC) program. We investigated the impact of a pharmacist-driven ARV stewardship and TOC program in persons with HIV. Methods This was a retrospective, quasi-experimental analysis evaluating the impact of an HIV-trained clinical pharmacist on hospitalized persons with HIV. Patients included in the study were adults following up, or planning to follow up, at the University of Illinois (UI) outpatient clinics for HIV care and admitted to the University of Illinois Hospital. Data were collected between July 1, 2017 and December 31, 2017 for the preimplementation phase and between July 1, 2018 and December 31, 2018 for the postimplementation phase. Primary and secondary endpoints included medication error rates related to antiretroviral therapy (ART) and opportunistic infection (OI) medications, all-cause readmission rates, medication access at time of hospital discharge, and linkage to care rates. Results A total of 128 patients were included in the study: 60 in the preimplementation phase and 68 in the postimplementation phase. After the implementation of this program, medication error rates associated with ART and OI medications decreased from 17% (10 of 60) to 6% (4 of 68) (P = .051), 30-day all-cause readmission rates decreased significantly from 27% (16 of 60) to 12% (8 of 68) (P = .03), and linkage to care rates increased significantly from 78% (46 of 59) to 92% (61 of 66) (P = .02). Conclusions A pharmacist-led ARV stewardship and TOC program improved overall care of persons with HIV through reduction in medication error rates, all-cause readmission rates, and an improvement in linkage to care rates.

Abstract
C. difficile infections (CDI) are increasingly recognized as a leading cause of infectious diarrhea, with increasing morbidity and mortality. Treatment primarily centers around oral vancomycin treatment. A wide range of dosing regimens exist in clinical practice, with little evidence to help distinguish the therapeutic benefit between them. This is a retrospective cohort study conducted at an academic medical center that enrolled adult patients admitted with CDI. The primary outcome was a composite of complete or partial cure at the end of treatment and was assessed using a test of equivalency with a 20% equivalency limit. Subjects were divided into low dose (125 mg) or high dose (250 mg or 500 mg) of oral vancomycin dosed every 6 hours. Overall, 78 patients were included who received low dose vancomycin and 33 who received high dose. Generally, the two groups were similar, except the low dose group had significantly more leukocytosis and less ICU admission or hypotension compared to the high dose group. Equivalency between the two treatment groups was demonstrated (Absolute Risk Difference -0.022, 90% confidence interval: -0.13 to 0.18, p = 0.03). A stepwise logistic regression identified gender, baseline albumin, and ICU admission as significant predictors of the chance for complete or partial cure. No differences between groups for the secondary outcomes of 90-day readmission/recurrence, 30-day all-cause mortality, or time to resolution of diarrhea were demonstrated. Low dose oral vancomycin was demonstrated to result in equivalent outcomes compared to high dose vancomycin for the treatment of CDI.

Abstract
BackgroundIn 2012, Israel's National Center for Infection Control initiated a national stewardship programme that included mandatory annual reporting of antimicrobial use. Here we present nationwide Israeli data for the period 2012 to 2017.AimThe goal of this study was to detect trends in antimicrobial use in Israel following the introduction of the stewardship programme, as part of an assessment of the programme's impact.MethodsIn this retrospective observational study, data were collected from Israel's health maintenance organisations (HMOs), acute care hospitals and post-acute care hospitals (PACHs). Acute care hospital data were collected for general medical and surgical wards, and medical/surgical intensive care units (ICUs). Data were converted into defined daily doses (DDD), with use rates presented as DDD per 1,000 insured/day in the community and DDD per 100 patient-days in hospitals and PACHs. Trends were analysed using linear regression.ResultsAntimicrobial use decreased across sectors between 2012 and 2017. In the community, the decrease was modest, from 22.8 to 21.8 DDD per 1,000 insured per day (4.4%, p = 0.004). In acute care hospitals, antibiotic DDDs per 100 patient-days decreased from 100.0 to 84.0 (16.0%, p = 0.002) in medical wards, from 112.8 to 94.2 (16.5%, p = 0.004) in surgical wards and from 154.4 to 137.2 (11.1%, p = 0.04) in ICUs. Antimicrobial use decreased most markedly in PACHs, from 29.1 to 18.1 DDD per 100 patient-days (37.8%, p = 0.005).ConclusionBetween 2012 and 2017, antimicrobial use decreased significantly in all types of healthcare institutions in Israel, following the introduction of the nationwide antimicrobial stewardship programme.

Practical Comparison of the BioFire FilmArray Pneumonia Panel to Routine Diagnostic Methods and Potential Impact on Antimicrobial Stewardship in Adult Hospitalized Patients with Lower Respiratory Tract Infections. J Clin Microbiol 2020; 58:JCM.00135-20. [PMID: 32350045 PMCID: PMC7315039 DOI: 10.1128/jcm.00135-20] [Citation(s) in RCA: 111] [Impact Index Per Article: 27.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2020] [Accepted: 04/01/2020] [Indexed: 12/16/2022] Open
Abstract
Lower respiratory tract infections, including hospital-acquired and ventilator-associated pneumonia, are common in hospitalized patient populations. Standard methods frequently fail to identify the infectious etiology due to the polymicrobial nature of respiratory specimens and the necessity of ordering specific tests to identify viral agents. The potential severity of these infections combined with a failure to clearly identify the causative pathogen results in administration of empirical antibiotic agents based on clinical presentation and other risk factors. Lower respiratory tract infections, including hospital-acquired and ventilator-associated pneumonia, are common in hospitalized patient populations. Standard methods frequently fail to identify the infectious etiology due to the polymicrobial nature of respiratory specimens and the necessity of ordering specific tests to identify viral agents. The potential severity of these infections combined with a failure to clearly identify the causative pathogen results in administration of empirical antibiotic agents based on clinical presentation and other risk factors. We examined the impact of the multiplexed, semiquantitative BioFire FilmArray Pneumonia panel (PN panel) test on laboratory reporting for 259 adult inpatients submitting bronchoalveolar lavage (BAL) specimens for laboratory analysis. The PN panel demonstrated a combined 96.2% positive percent agreement (PPA) and 98.1% negative percent agreement (NPA) for the qualitative identification of 15 bacterial targets compared to routine bacterial culture. Semiquantitative values reported by the PN panel were frequently higher than values reported by culture, resulting in semiquantitative agreement (within the same log10 value) of 43.6% between the PN panel and culture; however, all bacterial targets reported as >105 CFU/ml in culture were reported as ≥105 genomic copies/ml by the PN panel. Viral targets were identified by the PN panel in 17.7% of specimens tested, of which 39.1% were detected in conjunction with a bacterial target. A review of patient medical records, including clinically prescribed antibiotics, revealed the potential for antibiotic adjustment in 70.7% of patients based on the PN panel result, including discontinuation or de-escalation in 48.2% of patients, resulting in an average savings of 6.2 antibiotic days/patient.

Abstract
BACKGROUND Discontinuation of inappropriate antimicrobial therapy is an important target for stewardship intervention. The drug and duration-dependent effects of antibiotics on the developing neonatal gut microbiota needs to be precisely quantified. METHODS In this retrospective, cross-sectional study, we performed 16S rRNA sequencing on stool swab samples collected from neonatal intensive care unit patients within 7 days of discontinuation of therapy who received ampicillin and tobramycin (AT), ampicillin and cefotaxime (AC), or ampicillin, tobramycin, and metronidazole (ATM). We compared taxonomic composition within term and preterm infant groups between treatment regimens. We calculated adjusted effect estimates for antibiotic type and duration of therapy on the richness of obligate anaerobes and known butyrate-producers in all infants. RESULTS A total of 72 infants were included in the study. Term infants received AT (20/28; 71%) or AC (8/28; 29%) with median durations of 3 and 3.5 days, respectively. Preterm infants received AT (32/44; 73%) or ATM (12/44; 27%) with median durations of 4 and 7 days, respectively. Compositional analyses of 67 stool swab samples demonstrated low diversity and dominance by potential pathogens. Within 1 week of discontinuation of therapy, each additional day of antibiotics was associated with lower richness of obligate anaerobes (adjusted risk ratio [aRR], 0.84; 95% confidence interval [CI], .73-.95) and butyrate-producers (aRR, 0.82; 95% CI, .67-.97). CONCLUSIONS Each additional day of antibiotics was associated with lower richness of anaerobes and butyrate-producers within 1 week after therapy. A longitudinally sampled cohort with preexposure sampling is needed to validate our results.

Impact of a Diagnosis-Centered Antibiotic Stewardship on Incident Clostridioides difficile Infections in Older Inpatients: An Observational Study. Antibiotics (Basel) 2020; 9:antibiotics9060303. [PMID: 32517086 PMCID: PMC7345193 DOI: 10.3390/antibiotics9060303] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2020] [Revised: 05/27/2020] [Accepted: 06/04/2020] [Indexed: 12/17/2022] Open
Abstract
In 2015, a major increase in incident hospital-onset Clostridioides difficile infections (HO-CDI) in a geriatric university hospital led to the implementation of a diagnosis-centered antibiotic stewardship program (ASP). We aimed to evaluate the impact of the ASP on antibiotic consumption and on HO-CDI incidence. The intervention was the arrival of a full-time infectiologist in the acute geriatric unit in May 2015, followed by the implementation of new diagnostic procedures for infections associated with an antibiotic withdrawal policy. Between 2015 and 2018, the ASP was associated with a major reduction in diagnoses for inpatients (23% to 13% for pneumonia, 24% to 13% for urinary tract infection), while median hospital stays and mortality rates remained stable. The reduction in diagnosed bacterial infections was associated with a 45% decrease in antibiotic consumption in the acute geriatric unit. HO-CDI incidence also decreased dramatically from 1.4‰ bed-days to 0.8‰ bed-days in the geriatric rehabilitation unit. The ASP focused on reducing the overdiagnosis of bacterial infections in the acute geriatric unit was successfully associated with both a reduction in antibiotic use and a clear reduction in the incidence of HO-CDI in the geriatric rehabilitation unit.

Abstract
AIM Our aim was to determine the effectiveness and safety of a procalcitonin-guided protocol to decrease antibiotic use in infants with severe bronchiolitis. METHODS This prospective, observational study was conducted at the Hospital Sant Joan de Déu from 2010 to 2017. Patients under the age of one were included if they were diagnosed with bronchiolitis, had a suspected bacterial infection and were admitted to the paediatric intensive care unit. A procalcitonin-guided protocol was established in 2014, and two cohorts were compared before and after implementation: 340 in 2010-2014 and 366 in 2015-2017. RESULTS We recruited 706 patients (58.6% male) with a median age of 47 days and an interquartile range of 25.0-100.2. The rate for antibiotic use was 79.9%, and this differed before and after implementation (88.2% vs 72.1%, P = .003). Antibiotic stewardship and withdrawal decisions were higher after implementation (22.3% vs 36.4%, P = .005). The length of antibiotic treatment was also different between the two periods (8.65 ± 4.8 days vs 5.05 ± 3.18 days, P = .023). No adverse outcomes were observed due to the implementation of the protocol. CONCLUSION The implementation of a procalcitonin-guided protocol seems to lead to a safe and general decrease in antibiotic use in paediatric patients with severe bronchiolitis.

Abstract
In the United States of America, pharmacists play a pivotal role in antimicrobial stewardship; training from postgraduate residency may hone knowledge and skills gained from didactic pharmacy education. Specifically, the first year of postgraduate training, the learner may become an “everyday steward in training” and may go on to complete a second year in infectious diseases. However, there are a limited number of second year infectious diseases programs. The current demand for pharmacist to participate in and or lead stewardship is disproportionate to available specialized training. The first year of post-graduate training has to be setup to ensure appropriate preparation, so newly trained pharmacist may help meet the demand. Currently, no clear standards exist for training in the first year. The purpose of this study is to survey the nature of stewardship training performed by first year residents from the perspective of residency program directors and preceptors. A 13-question online survey was distributed to examine resident exposure to antimicrobial stewardship activities. Survey data from targeted residency directors and preceptors were analyzed. A third of the programs required it as a mandatory rotation. Resident’s stewardship activities ranged from program to program; there was not consensus of the training activities.

Abstract
Persons living with human immunodeficiency virus (HIV) and others receiving antiretrovirals are at risk for medication errors during hospitalization and at transitions of care. These errors may result in adverse effects or viral resistance, limiting future treatment options. A range of interventions is described in the literature to decrease the occurrence or duration of medication errors, including review of electronic health records, clinical checklists at care transitions, and daily review of medication lists. To reduce the risk of medication-related errors, antiretroviral stewardship programs (ARVSPs) are needed to enhance patient safety. This call to action, endorsed by the Infectious Diseases Society of America, the HIV Medicine Association, and the American Academy of HIV Medicine, is modeled upon the success of antimicrobial stewardship programs now mandated by the Joint Commission. Herein, we propose definitions of ARVSPs, suggest resources for ARVSP leadership, and provide a summary of published, successful strategies for ARVSP that healthcare facilities may use to develop locally appropriate programs.
