Abstract
BACKGROUND Infectious conjunctivitis affects one in eight children annually, resulting in high ophthalmic antibiotic prescribing and absenteeism from childcare and school. We aimed to quantify the cost-effectiveness and annual savings of three evidence-based approaches to conjunctivitis management and return to childcare and school compared to usual care. METHODS Using a decision analytic model from a societal perspective over a one-year time horizon, we conducted a cost-effectiveness analysis of three management strategies for children aged 6 months-17 years with non-severe conjunctivitis compared to usual care in the United States. Strategies accounted for rate of transmission. Strategies included 1) refraining from prescribing ophthalmic antibiotics for non-severe conjunctivitis, 2) allowing children without systemic symptoms to attend childcare and school, 3) and the combined approach of refraining from prescribing ophthalmic antibiotics and allowing children without systemic symptoms to attend childcare and school. RESULTS The estimated annual expenditure for pediatric conjunctivitis was $1.95 billion. Usual care was the most expensive ($212.73/episode), followed by refraining from ophthalmic antibiotic prescribing ($199.92) and allowing children without systemic symptoms to attend childcare and school ($140.18). The combined approach was the least costly ($127.38). Disutility was similar between approaches (quality adjusted life days 0.271 v 0.274). Refraining from antibiotic prescribing and the combination approach were dominant compared to usual care. The combined approach resulted in an estimated $783 million annual savings and 1.6 million ophthalmic antibiotic courses averted. CONCLUSIONS Conjunctivitis poses an economic burden which could be reduced by refraining from ophthalmic antibiotic use and allowing children without systemic symptoms to remain at school or childcare.

The role of clinical pharmacists in patients with suspected allergy to β-lactams: A systematic review. FARMACIA HOSPITALARIA 2024; 48:38-44. [PMID: 37696709 DOI: 10.1016/j.farma.2023.07.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2023] [Revised: 07/25/2023] [Accepted: 07/28/2023] [Indexed: 09/13/2023] Open
Abstract
OBJECTIVE To analyze the role played by the clinical pharmacist and its impact in antibiotic stewardship facing suspected allergy to beta-lactam antibiotics. METHOD We performed two different independent bibliographic searches. A total of 35 articles were found, and the final number included in the study was 12. We analysed the articles and collected variables of efficacy, safety and applicability of evaluation tools applied to patients with suspected allergy to beta-lactams. Also, the variation in the consumption and prescription profile of alternative antibiotics was analyzed. RESULTS The selected studies analysed questionnaires, allergy delabeling, intradermal tests and oral challenge tests performed by pharmacists. Significant differences in the efficacy endpoint were found in 4 studies in favour of pharmaceutical intervention. In the study of Kwiatkowski et al, cefazolin use increased in surgical patients after pharmacist intervention (65 vs. 28%; p < 0.01). In a quasi-experimental study, the mean defined daily dose of aztreonam and the mean days of therapy per 1000 patients/day decreased (21.23 vs 9.05, p <0.01) and (8.79-4.24, p = 0.016), pre and post-intervention, respectively, increasing antibiotic de-escalations (p ≤ 0.01). In another quasi-experimental study, the prescription of restricted-use antibiotics decreased (42.5% vs. 17.9%, p < 0.01) and the use of pre-surgical prophylactic antibiotics alternative to cefazolin (81.9% vs 55.9%, p<0.01) in another study. Other study showed that the mean time per interview was 5.2 minutes per patient. No adverse events were reported in any study. CONCLUSION The pharmacist intervention in the evaluation of the patient with suspected allergy to beta-lactams is effective, safe and feasible to implement on daily clinical practice. The standardization of protocols to clarify the history of allergies and development of evaluation tools represent simple screenings to perform delabelling or refer to the Immunoallergology service, improving penicilins use and reducing the need for second line antibiotics. More studies are needed to standardize the desensitization tests made by pharmacists. However, despite these results, the involvement and leadership of the pharmacist in this area is limited and constitutes a future challenge for the profession.

Antibiotics resistance as a major public health concern: A pharmaco-epidemiological study to evaluate prevalence and antibiotics susceptibility-resistance pattern of bacterial isolates from multiple teaching hospitals. J Infect Public Health 2023; 16 Suppl 1:61-68. [PMID: 37880004 DOI: 10.1016/j.jiph.2023.09.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2023] [Revised: 09/22/2023] [Accepted: 09/27/2023] [Indexed: 10/27/2023] Open
Abstract
BACKGROUND Multi Drugs Resistance (MDR) is among the most worrisome healthcare issues resulting from inappropriate and indiscriminate utilization of antimicrobial agents which has compromised the efficacy and reliability of antimicrobial agents (AMAs). This has not only put a huge burden on the health care system but also is a major cause of morbidity and mortality. This project was designed to evaluate the prevalence of various microbial strains among patients admitted to various teaching hospitals and to assess their susceptibility and resistance towards clinically approved antibiotics. METHODS The study was conducted during August 2021-February 2022 to determine the prevalence of common resistant strains of bacteria and to analyze their susceptibility pattern to the commonly prescribed antibiotics using standard procedures. One hundred and thirty biological samples including urine, blood, cerebrospinal fluid (CSF), wound swabs, pus and sputum were collected from the site of infection from the patients admitted at different wards of North West General Hospital (NWGH), Peshawar, Pakistan, Khyber Teaching Hospital (KTH), Peshawar Pakistan, and Hayat Abad Medical Complex (HMC) Peshawar Pakistan. Samples were collected and cultured following standard hospital procedures. The cultured samples were subjected to identification procedures including Gram staining, morphological characterization of bacterial colonies and biochemical assessments. The identified bacteria were tested for their susceptibility using Kirby-Bauer disc diffusion method. The diameter of Inhibitory Zones (DIZ) was analyzed following Clinical and Laboratory Standards Institute (CLSI) criteria. Minimum Inhibitory Concentrations (MICs) were evaluated using agar dilution method. Antimicrobials sensitivity were presented as antibiogram following CLSI M39 standard. RESULTS A total of one hundred and thirty biological samples were collected, out of which one hundred and nine samples were positive for bacterial growth and were further processed for detailed analysis. The frequency and type of bacteria isolated from various cultures indicated that Gram negative bacteria (n = 92/109) were more dominant than Gram-positive (n = 17/109) pathogens. The most prevalent bacteria isolated was Escherichia coli (29.35 %), followed by Staphylococcus aureus (15.59 %), and Klebsiella spp, (12.84 %). In addition, other pathogens including, Enterobacter spp, Citrobacter spp, and Acinetobacter spp. showed a prevalence of 9.175 %, 8.25 %, and 5.50 % respectively. As indicated in the antbiogram, several organisms exhibited considerble decline in the sensitivies towards various antibiotics. A high percentage of resistance was observed against some antibiotics including trimethoprim, co-trimoxazole, amoxicillin/clavulanate, ciprofloxacin, piperacillin/tazobactam, cefotaxime and ceftazidime. CONCLUSION The prevalence of resistant strains of pathogens is increasing day by day, while the antibiotics commonly prescribed against them are losing their efficacy, which is pushing the world to the era of pre-antibiotics. Unfortunately, the discovery of novel antibiotics is limited and researchers speculate that the is pushing towards pre-antibiotics era. Subsequently, efforts must be directed towards ensuring rational antibiotics use to prevent emergence of MDR pathogens. Our findings indicated that Gram negative bacteria including Escherichia coli was most prevalent. Other bacterial strains including S. aureus, Klebsiella spp, Enterobacter spp, Citrobacter spp, and Acinetobacter spp. were found among the causative agents. Unfortunately, considerable decline in the sensitivities of various bacterial isolated were observed towards the tested antibiotics. Previous studies reported the high prevalence of E. coli and S. aureus in clinical samples of Pakistani hospitals including hospitals in Peshawar and thus our findings are in agreement with the previous reports. Pharmacists being experts can play their role by promoting the optimal use of antimicrobial agents and educating healthcare professionals, patients and the public.

Abstract
BACKGROUND Procalcitonin (PCT), a peptide precursor of the hormone calcitonin, is a biomarker whose serum concentrations are elevated in response to systemic inflammation caused by bacterial infection and sepsis. Clinical adoption of PCT in the United States has only recently gained traction with an increasing number of Food and Drug Administration-approved assays and expanded indications for use. There is interest in the use of PCT as an outcomes predictor as well as an antibiotic stewardship tool. However, PCT has limitations in specificity, and conclusions surrounding its utility have been mixed. Further, there is a lack of consensus regarding appropriate timing of measurements and interpretation of results. There is also a lack of method harmonization for PCT assays, and questions remain regarding whether the same clinical decision points may be used across different methods. CONTENT This guidance document aims to address key questions related to the use of PCT to manage adult, pediatric, and neonatal patients with suspected sepsis and/or bacterial infections, particularly respiratory infections. The document explores the evidence for PCT utility for antimicrobial therapy decisions and outcomes prediction. Additionally, the document discusses analytical and preanalytical considerations for PCT analysis and confounding factors that may affect the interpretation of PCT results. SUMMARY While PCT has been studied widely in various clinical settings, there is considerable variability in study designs and study populations. Evidence to support the use of PCT to guide antibiotic cessation is compelling in the critically ill and in some lower respiratory tract infections but is lacking in other clinical scenarios, and evidence is also limited in the pediatric and neonatal populations. Interpretation of PCT results requires guidance from multidisciplinary care teams of clinicians, pharmacists, and clinical laboratorians.

Abstract
Antimicrobial resistance (AR) is a natural phenomenon resulting from the exposure of bacteria to antibacterial substances. The intestinal microbiome plays a central role in the development and transmission of AR. In its physiological state, the intestinal microbiome has several mechanisms that contribute to what is referred to as colonization resistance against potentially pathogenic and often multiresistant bacteria. Exposure to broad-spectrum antibiotics can disrupt those mechanisms, facilitating colonization with these pathogens. The persistence of antibiotic selection pressure favors growth of multiresistant bacteria and their dominance within the intestinal microbiota. Under these circumstances, the risk of the development of invasive infections increases. Antibiotic stewardship programs, the use of narrow-spectrum antibiotics, and the administration of substances that protect the intestinal microbiome from antibiotic exposure can prevent these processes. Several interventions such as the administration of probiotics, oral antibiotics, and fecal microbiome transfers are potential strategies for decolonizing patients with multidrug resistant bacteria; to date, however, no intervention has been proven to be consistently effective.

Ceftriaxone with Metronidazole versus Piperacillin/Tazobactam in the management of complicated appendicitis in children: Results from a multicenter pediatric NSQIP analysis. J Pediatr Surg 2022; 57:365-372. [PMID: 34876294 DOI: 10.1016/j.jpedsurg.2021.11.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2021] [Revised: 11/04/2021] [Accepted: 11/10/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND Narrow-spectrum antibiotics have been found to be equivalent to anti-Pseudomonal agents in preventing organ space infections (OSI) in children with uncomplicated appendicitis. Comparative effectiveness data for children with complicated appendicitis remains limited. This investigation aimed to compare outcomes between the most common narrow-spectrum regimen (ceftriaxone with metronidazole: CM) and anti-Pseudomonal regimen (piperacillin/tazobactam: PT) used perioperatively in children with complicated appendicitis. METHODS Multicenter retrospective cohort study using clinical data from the NSQIP-Pediatric Appendectomy Collaborative database merged with antibiotic utilization data from the Pediatric Health Information System database. Mixed-effects multivariate regression was used to compare NSQIP-defined outcomes and resource utilization between treatment groups after adjusting for patient characteristics, disease severity, and clustering of outcomes within hospitals. RESULTS 654 patients from 14 hospitals were included, of which 37.9% received CM and 62.1% received PT. Following adjustment, patients in both groups had similar rates of OSI (CM: 13.3% vs. PT: 18.0%, OR 0.88 [95%CI 0.38, 2.03]), drainage procedures (CM: 8.9% vs. PT: 14.9%, OR 0.76 [95%CI 0.30, 1.92]), and postoperative imaging (CM: 19.8% vs. PT: 22.5%, OR 1.17 [95%CI 0.65, 2.12]). Treatment groups also had similar rates of 30-day cumulative post-operative length of stay (CM: 6.1 vs. PT: 6.0 days, RR 1.01 [95%CI 0.81, 1.25]) and hospital cost (CM: $19,235 vs. PT: $20,552, RR 0.92 [95%CI 0.69, 1.23]). CONCLUSIONS Rates of organ space infection and resource utilization were similar in children with complicated appendicitis treated with ceftriaxone plus metronidazole and piperacillin/tazobactam.

Abstract
Hintergrund und Fragestellung Bei der pyogenen Spondylodiszitis gewinnen Infektionen mit Koagulase-negativen Staphylokokken zunehmend an Bedeutung. Eine empirische Antibiose ist insbesondere bei Patienten mit schweren oder progredienten neurologischen Ausfällen sowie hämodynamischer Instabilität und im Falle von kulturnegativen Spondylodiszitiden notwendig. Ob es in Deutschland einheitliche, an das Resistenzprofil angepasste Standards der empirische Antibotikatherapie gibt, ist unklar. Studiendesign und Untersuchungsmethoden Es wurde an deutschen Universitäts- und berufsgenossenschaftlichen Kliniken, jeweils in den Fachbereichen Orthopädie und Unfallchirurgie, eine Umfrage zur empirischen Antibiotikatherapie bei pyogener Spondylodiszitis durchgeführt. Die Umfrageergebnisse wurden auf das Resistenzprofil der Erreger von 45 Spondylodiszitispatienten, die zwischen 2013 und 2020 in unserer Klinik behandelt wurden, angewandt. Dadurch wurden potenzielle Sensibilitäts- und Resistenzraten für die angegebenen antibiotischen Therapien errechnet. Ergebnisse Von den 71 angefragten Kliniken antworteten insgesamt 44 (62,0 %). Sechzehn verschiedene Antibiotikatherapien wurden als jeweiliger Standard berichtet. Darunter wurden 14 verschiedene Kombinationstherapien als Therapiestandard angegeben. Die am häufigsten angegebenen empirischen Substanzen, nämlich Amoxicillin-Clavulansäure oder Ampicillin/Sulbactam (29,5 %) und Cephalosporine (18,2 %) zeigten in Bezug auf das zuvor veröffentliche Resistenzprofil hohe potenzielle Resistenzraten von 20,0 % bzw. 35,6 %. Die höchsten potenziellen Sensibilitätsraten wurden durch die Kombinationen Vancomycin + Ampicillin/Sulbactam (91,1 % sensible Erreger), Vancomycin + Piperacillin/Tazobactam (91,1 % sensible Erreger) und Ampicillin/Sulbactam + Teicoplanin (95,6 % sensible Erreger) erreicht. Eine dieser Kombinationen wurde von drei Kliniken (6,8 %) als Standard angegeben. Schlussfolgerung Die deutschlandweite Umfrage zur empirischen Antibiose bei pyogener Spondylodiszitis hat eine große Heterogenität der Standardtherapien ergeben. Eine Kombination aus einem Breitspektrum-β-Laktam-Antibiotikum mit einem zusätzlichen Glykopeptidantibiotikum kann sinnvoll sein.

A randomized control trial of a multiplex gastrointestinal PCR panel versus usual testing to assess antibiotics use for patients with infectious diarrhea in the emergency department. J Am Coll Emerg Physicians Open 2022; 3:e12616. [PMID: 35072157 PMCID: PMC8760946 DOI: 10.1002/emp2.12616] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2021] [Revised: 11/08/2021] [Accepted: 11/12/2021] [Indexed: 11/23/2022] Open
Abstract
OBJECTIVE This study analyzed physician treating behavior through the use of a multiplex gastrointestinal polymerase chain reaction (GI PCR) test compared with usual testing in emergency department (ED) patients with suspected acute infectious diarrhea to assess differences in antibiotic management. METHODS A prospective, single-center, randomized control trial was designed to investigate antibiotic use in ED patients with moderate to severe suspected infectious diarrhea, comparing those who received GI PCR to those who received usual testing. ED patients with signs of dehydration, inflammation, or persistent symptoms were randomized to either the experimental arm (GI PCR) or the control arm (usual testing or no testing). RESULTS A total of 74 patients met study criteria and were randomized to either the experimental GI PCR arm (n = 38) or to the control arm (n = 36). Participants in the GI PCR arm received antibiotics in 87% of bacterial or protozoal diarrheal infections (13/15) whereas those in the control arm received antibiotics in 46% of bacterial or protozoal infections (6/13) (P value 0.042) with 2-proportion difference 0.41 (95% confidence interval 0.07 and 0.68). CONCLUSIONS ED use of multiplex GI PCR led to an increase in antibiotic use for bacterial and protozoal causes of infectious diarrhea compared to usual testing. This increase in antibiotics appears to be appropriate given patients' moderate to severe symptoms and a definitive identification of a likely bacterial or protozoal cause of symptoms. Results should be interpreted with caution because of the small sample size.

Abstract
INTRODUCTION Ecuador is a lower-to-middle income country (LMIC) not yet adherent to World Health Organization Antibiotic Stewardship Strategies (WHO-ASI) and we still lack data regarding basic metrics. METHODS We conducted a retrospective study of an ASI consisting of a restrictive measure to carbapenems dispensation pending on required preauthorization and expert audit. We evaluated antibiotic consumption and its relationship to carbapenems resistance at a 610-bed, tertiary level hospital in Quito, Ecuador. We used prescription data from 2010 to 2017 and converted into Defined Daily Doses (DDD). We them correlated these findings with the nature of service provided and antibiotic resistance from microbiologic lab. We used descriptive statistics and interrupted time-series analysis. RESULTS Throughout the study period, we analyzed 16,984,355 prescriptions of 8,191,418.57 grams of antibiotics (5,760,479.37 DDD). The in-hospital mean (SD) antibiotic prescription was 148.8 (14.8) DDD/100 occupied bed-dayss and 293.5 (65.3) DDD/100 occupied bed-dayss in the ICU. First, second and third line antibiotics consumption were 38%, 52% and 10% respectively. Our hospital data showed a high rate of antibiotic prescription in all hospital areas, mainly broad-spectrum antibiotics. Regarding the ASI introduced in 2016, the interrupted time-series analysis showed a change in the outcome level immediately following the introduction for imipenem (-3.97; 95% CI -5.31 -2.61) but not for meropenem (0.66; 95%CI -0.37 1.71). CONCLUSION Even though our institution's ASI was successful in reducing imipenen consumption, a more embracing plan is required for further interventions to avoid unexpected effects.

Abstract
The neonatal population is at high risk for infections secondary to a unique, developing immune system. While a multitude of factors direct the development of the immune system, the role of environmental exposures on the microbiota may play a critical and potentially modifiable role. Recent evidence suggests that the disruption of the microbiota through the use of antibiotics not only leads to an immediately increased risk for neonatal complications but also long-term health issues related to autoimmune and inflammatory diseases. The exact cellular and molecular mechanisms behind these associations between the microbiota and neonatal outcomes are still under investigation. This review will examine the mechanistic interactions between the microbiota and the immune system, particularly in early life, along with how antibiotic mediated aberrations of the microbiome potentially lead to disease.

Abstract
BACKGROUND Inappropriate use of antibiotics can lead to the development of resistant pathogens. Ensuring proper use of these important drugs in all healthcare facilities is essential. Unfortunately, however, very little is known about how antibiotics are used in LMIC clinical settings, nor to what degree antibiotic stewardship programmes are in place and effective. OBJECTIVE We aimed to record all Antibiotic Stewardship policies and structures in place in 16 Kenyan hospitals. We also wanted to examine the context of antibiotic-related practices in these hospitals. METHODS We generated a set of questions intended to assess the knowledge and application of antibiotic stewardship policies and practices in Kenya. Using a set of 17 indicators grouped into four categories, we surveyed 16 public hospitals across the country. Additionally, we conducted 31semi-structured interviews with frontline healthcare workers and hospital managers to explore the context of, and reasons for, the results. RESULTS Only one hospital had a resourced ABS policy in place. In all other hospitals, our survey teams commonly identified structures, resources and processes that in some way demonstrated partial or full control of antibiotic usage. This was verified by the qualitative interviews that identified common underlying issues. Most positively, we find evidence discipline-specific clinical guidelines have been well accepted and have conditioned and restricted antibiotic use. CONCLUSION Only one hospital had an official ABS programme, but many facilities had existing structures and resources that could be used to improve antibiotic use. Thus, ABS Strategies should be built upon existing practices with national ABS policies taking maximum advantage of existing structures to manage the supply and prescription of antimicrobials. We conclude that ABS interventions that build on established responsibilities, methods and practices would be more efficient than interventions that presume a need to establish new ABS apparatus.

Abstract
Antibiotic stewardship (ABS) comprises a bundle of different interventions to improve anti-infective treatment in a hospital setting. An important component of ABS interventions is the interdisciplinary approach to infection management. Besides improving infrastructural aspects on a hospital level, including surveillance of the use of anti-infective agents and nosocomial infections, collation and interpretation of statistics on resistance and formulation of local treatment guidelines, ABS teams go to the wards and advise treating physicians on antibiotic therapy. Frequent approaches for optimization are selection of substances, administration route, dosing of medication and duration of treatment. An important overall objective of ABS is the reduction of resistance induction in order to preserve the therapeutic efficiency of antibiotics. A number of studies have shown that this goal can be achieved in different clinical settings without negatively affecting patient outcome. The strategies of ABS can also be applied with no problems to critically ill patients on the intensive care unit.

Abstract
INTRODUCTION Compared with younger populations, adults 65 years and older are more likely to suffer infection-related morbidity and mortality, experience antibiotic-related adverse events, and acquire multidrug-resistant organisms. We developed a series of case-based discussions that stressed antibiotic stewardship while addressing management of common infections in older adults. METHODS Five 1-hour case-based discussions address recognition, diagnosis, and management of infections common in older adults, including those living in long-term care settings: urinary tract infections, upper respiratory tract infections, lower respiratory tract infections, skin and soft tissue infections, and Clostridium difficile infection. The education was implemented at the skilled nursing centers at 15 Veterans Affairs medical centers. Participants from an array of disciplines completed an educational evaluation for each session as well as a pre- and postcourse knowledge assessment. RESULTS The number of respondents to the educational evaluation administered following each session ranged from 68 to 108. Learners agreed that each session met its learning objectives (4.80-4.89 on a 5-point Likert scale, 5 = strongly agree) and that they were likely to make changes (2.50-2.89 on a 3-point scale, 3 = highly likely to make changes). The average score on the five-question knowledge assessment increased from 3.6 (72%) to 3.9 (78%, p = .06). DISCUSSION By stressing recognition of atypical signs and symptoms of infection in older adults, diagnostic tests, and antibiotic stewardship, this series of five case-based discussions enhanced clinical training of learners from several disciplines.

Introduction Given the increasing importance of antibiotic stewardship, an understanding of the basic tenets of antibiotic prescribing is critical for all medical students. This engaged learning module focuses on terminology and foundational concepts in antibiotic stewardship while assisting learners with application in their early clinical practice. Methods This module was developed for third-year internal medicine clerkship students at the University of South Dakota, Sanford School of Medicine. The students participated in an introductory discussion of the harms of antibiotic overuse in a large-group format, followed by small-group work to develop a miniature antibiotic stewardship program. Upon completion of the small-group portion, the large group reconvened to share antibiotic stewardship strategies and to complete the session with additional training regarding individual provider and system-level antibiotic stewardship strategies. Results Approximately 150 students have participated in this module. Through use of the module, students have been highly engaged in identifying antibiotic stewardship interventions in their early practice and creating potential solutions. Themes identified during analysis of one-minute paper responses demonstrated student learning around the rationale for antibiotic stewardship programs, implementation strategies, and patient education. Discussion This module was primarily developed for medical students, but it could easily be adapted for use with learners of varying levels. Additionally, it could be implemented as an interprofessional exercise to leverage the expertise of trainees in pharmacy and nursing.

Can rapid negative exclusion of blood cultures by a molecular method, enzyme template generation and amplification technique (Cognitor ® Minus), aid antimicrobial stewardship? INTERNATIONAL JOURNAL OF PHARMACY PRACTICE 2017; 26:267-272. [PMID: 28833759 PMCID: PMC5969237 DOI: 10.1111/ijpp.12393] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2016] [Accepted: 07/04/2017] [Indexed: 11/29/2022]
Abstract
OBJECTIVES Antimicrobial review is an important part of antimicrobial stewardship. A novel enzyme template generation and amplification technique (ETGA), the Cognitor® Minus (Momentum Bioscience, Long Hanborough, UK) test, has a 99.5% negative predictive value for bacteraemia and fungaemia. This observational study asked two questions: (1) Does a negative ETGA, indicating no bacteraemia or fungaemia, aid antimicrobial review within 48 h of admission; (2) In this real-life clinical setting, does a negative ETGA mean no bacteraemia or fungaemia? METHODS Consecutive blood cultures in patients with clinical infection were tested by ETGA. Negative results indicating an absence of bacteraemia or fungaemia were reviewed by the clinical infection team. Antibiotics were reviewed in these patients, and the role of the ETGA result in antibiotic change was recorded. Patients were followed up for a week. KEY FINDINGS A total of 197 of 246 samples gave a negative result by ETGA. This led to a positive stewardship outcome (antimicrobials changed) in 145 (73.6%) and negative stewardship outcome (empirical antimicrobials continued) in 47 (23.9%). Of the positive stewardship outcomes, the ETGA result supported the decision not to start antimicrobials in 21 (10.7%) patients, to stop antimicrobials in 21 (10.7%), to switch from IV to oral antimicrobials in 103 (52.2%) or to discharge or leave the patient at home in 58 cases (29.4%). CONCLUSIONS Enzyme template generation and amplification supports antimicrobial stewardship decisions and may have cost advantages in reducing unnecessary empirical antibiotics and antifungal agents and in discharging patients from hospital earlier. ETGA result was consistent with blood culture findings and gave an earlier negative result.

A Systematic Review of Quality Indicators for Appropriate Antibiotic Use in Hospitalized Adult Patients. Infect Dis Rep 2017; 9:6821. [PMID: 28458795 PMCID: PMC5391534 DOI: 10.4081/idr.2017.6821] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/04/2016] [Revised: 10/17/2016] [Accepted: 12/20/2016] [Indexed: 12/04/2022] Open
Abstract
Many quality indicators for appropriate antibiotic use have been developed. We aimed to make a systematic inventory, including the development methodology and validation procedures, of currently available quality indicators (QIs) for appropriate antibiotic use in hospitalized adult patients. We performed a literature search in the Pubmed interface. From the included articles we abstracted i) the indicators developed ii) the type of infection the QIs applied to iii) study design used for the development of the QIs iv) relation of the QIs to outcome measures v) whether the QIs were validated and vi) the characteristics of the validation cohort. Fourteen studies were included, in which 200 QIs were developed. The most frequently mentioned indicators concerned empirical antibiotic therapy according to the guideline (71% of studies), followed by switch from IV to oral therapy (64% of studies), followed by drawing at least two sets of blood cultures and change to pathogen-directed therapy based on culture results (57% of studies). Most QIs were specifically developed for lower respiratory tract infection, urinary tract infection or sepsis. A RAND-modified Delphi procedure was used in the majority of studies (57%). Six studies took outcome measures into consideration during the procedure. Five out of fourteen studies (36%) tested the clinimetric properties of the QIs and 65% of the tested QIs were considered valid. Many studies report the development of quality indicators for appropriate antibiotic use in hospitalized adult patients. However, only a small number of studies validated the developed QIs. Future validation of QIs is needed if we want to implement them in daily practice.

Abstract
International and national campaigns draw attention worldwide to the rational use of the available antibiotics. This has been stimulated by the high prevalence rates of drug-resistant pathogens, such as methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE), a threatening spread of development of resistance in Gram-negative rod-shaped bacteria and the selection of Clostridium difficile with a simultaneous clear reduction in the development of new antibiotics. The implementation of antibiotic stewardship programs aims to maintain their effectiveness by a rational use of the available antibiotics. The essential target of therapy with antibiotics is successful treatment of individual patients with bacterial infections. The optimal clinical treatment results can only be achieved when the toxicity, selection of pathogens and development of resistance are minimized. This article presents the principles of a rational antibiotic therapy.

A disruptive Big data approach to leverage the efficiency in management and clinical decision support in a Hospital. Porto Biomed J 2016; 1:40-42. [PMID: 32258546 DOI: 10.1016/j.pbj.2015.12.001] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2015] [Accepted: 12/10/2015] [Indexed: 10/21/2022] Open
Abstract
There is an urgent need to potentiate evidence-based clinical-decision-making with a holistic, patient-centered approach to value, one that focuses both on health-care spending and treatment outcomes.1 On the other hand, in the era of self-driven vehicles, computer systems in healthcare need also to become proactive and to identify relevant clinical patterns in a much faster and automated way than currently used solutions enable. Although this is the state-of-the-art paradigm, in fact, technical constraints block further developments in these areas as hospitals lack the skills to really manage and take value from the big amount of Data about their patients that is stored in dozens of heterogeneous information systems, from lab results to imaging studies, from pharmacy to the Electronic Medical Record (EMR). At São João Hospital Center (São João), a novel analytics platform was conceived, a new approach that is able to leverage all the Big Data that is stored about hospital patients in seconds and to apply some of the most advanced and lightening speed analytics on top of this information in order to empower clinicians and to give them a new decision support tool. This sets the road towards a data-driven hospital of the future, where Data Analytics and Data Science can become as important as the most recent Harrison's edition. With this analytics platform, São João was able to be the first Non-Us institution to ever win the Microsoft U.S Worldwide Innovation Award (HIMSS - Florida, 2014) and the European Big Data & Analytics solution of the year (IT EUROPA - London, 2014). This solution is called HVITAL (Hospital surVeiIlance, moniToring and ALert) and is working 24/7 at São João Hospital since 2012.

Abstract
INTRODUCTION One of the core strategies to optimize antiinfective therapy is to review antibiotic prescriptions. Therefore, Antibiotic Stewardship (ABS) team members either attend ward rounds or perform a chart review to provide feedback to and discuss with the attending physician. Acceptance and effectiveness of both options are discussed in this article. METHODS Attending physicians were asked to complete a questionnaire evaluating ABS activities. The modality of the reviewing process and its effectiveness, as well as the feasibility of recommendations was assessed. As the degree of implementation of ABS recommendations decreased on a trauma ward, the reviewing process was changed from chart review to attending the daily ward rounds. In this setting, the duration of the reviewing process and the consumption of antiinfectives in recommended daily doses/100 patient days (RDD/100PT) were assessed, comparing the two intervention modalities. RESULTS Attending physicians predominantly appreciated the modality and extent of ABS currently offered to them by the ABS team, rating it relevant and effective. Implementation of ABS recommendations was increased on the trauma ward by academic detailing during the daily ward round; the consumption of broad spectrum antibiotics was reduced. DISCUSSION ABS team members with formal authority and dedicated time for antibiotic stewardship activities effectively optimize antiinfective therapies by reviewing antibiotic prescriptions. The interaction of ABS experts and attending physicians contributes fundamentally to the effectiveness and degree of implementation of ABS interventions.

Abstract
These guidelines, written for clinicians, contains evidence-based recommendations for the prevention of hospital acquired infections Hospital acquired infections are a major cause of mortality and morbidity and provide challenge to clinicians. Measures of infection control include identifying patients at risk of nosocomial infections, observing hand hygiene, following standard precautions to reduce transmission and strategies to reduce VAP, CR-BSI, CAUTI. Environmental factors and architectural lay out also need to be emphasized upon. Infection prevention in special subsets of patients - burns patients, include identifying sources of organism, identification of organisms, isolation if required, antibiotic prophylaxis to be used selectively, early removal of necrotic tissue, prevention of tetanus, early nutrition and surveillance. Immunodeficient and Transplant recipients are at a higher risk of opportunistic infections. The post tranplant timetable is divided into three time periods for determining risk of infections. Room ventilation, cleaning and decontamination, protective clothing with care regarding food requires special consideration. Monitoring and Surveillance are prioritized depending upon the needs. Designated infection control teams should supervise the process and help in collection and compilation of data. Antibiotic Stewardship Recommendations include constituting a team, close coordination between teams, audit, formulary restriction, de-escalation, optimizing dosing, active use of information technology among other measure. The recommendations in these guidelines are intended to support, and not replace, good clinical judgment. The recommendations are rated by a letter that indicates the strength of the recommendation and a Roman numeral that indicates the quality of evidence supporting the recommendation, so that readers can ascertain how best to apply the recommendations in their practice environments.
