Infection 2021; 49:1299-1306. [PMID: 34687426 PMCID: PMC8536912 DOI: 10.1007/s15010-021-01720-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2021] [Accepted: 10/12/2021] [Indexed: 01/08/2023]
Abstract
Purpose Thorough knowledge of the nature and frequency of co-infections is essential to optimize treatment strategies and risk assessment in cases of coronavirus disease 2019 (COVID-19). This study aimed to evaluate the multiplex polymerase chain reaction (PCR) screening approach for community-acquired bacterial pathogens (CABPs) at hospital admission, which could facilitate identification of bacterial co-infections in hospitalized COVID-19 patients. Methods Clinical data and biomaterials from 200 hospitalized COVID-19 patients from the observational cohort of the Competence Network for community-acquired pneumonia (CAPNETZ) prospectively recruited between March 17, 2020, and March 12, 2021 in 12 centers in Germany and Switzerland, were included in this study. Nasopharyngeal swab samples were analyzed on hospital admission using multiplex real-time reverse transcription (RT)-PCR for a broad range of CABPs. Results In total of 200 patients Staphylococcus aureus (27.0%), Haemophilus influenzae (13.5%), Streptococcus pneumoniae (5.5%), Moraxella catarrhalis (2.5%), and Legionella pneumophila (1.5%) were the most frequently detected bacterial pathogens. PCR detection of bacterial pathogens correlated with purulent sputum, and showed no correlation with ICU admission, mortality, and inflammation markers. Although patients who received antimicrobial treatment were more often admitted to the ICU and had a higher mortality rate, PCR pathogen detection was not significantly related to antimicrobial treatment. Conclusion General CABP screening using multiplex PCR with nasopharyngeal swabs may not facilitate prediction or identification of bacterial co-infections in the early phase of COVID-19-related hospitalization. Most patients with positive PCR results appear to be colonized rather than infected at that time, questioning the value of routine antibiotic treatment on admission in COVID-19 patients.

[PMID: 34670500 PMCID: PMC8527685 DOI: 10.1186/s12879-021-06794-1] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2021] [Accepted: 10/12/2021] [Indexed: 11/10/2022] Open
Abstract
Background Penicillin allergy prevalence is internationally reported to be around 10%. However, the majority of patients who report a penicillin allergy do not have a clinically significant hypersensitivity. Few patients undergo evaluation, which leads to overuse of broad-spectrum antibiotics. The objective of this study was to monitor prevalence and implement screening and testing of hospitalized patients. Methods All patients admitted to the medical department in a local hospital in Oslo, Norway, with a self-reported penicillin allergy were screened using an interview algorithm to categorize the reported allergy as high-risk or low-risk. Patients with a history of low-risk allergy underwent a direct graded oral amoxicillin challenge to verify absence of a true IgE-type allergy. Results 257 of 5529 inpatients (4.6%) reported a penicillin allergy. 191 (74%) of these patients underwent screening, of which 86 (45%) had an allergy categorized as low-risk. 54 (63%) of the low-risk patients consented to an oral test. 98% of these did not have an immediate reaction to the amoxicillin challenge, and their penicillin allergy label could thus be removed. 42% of the patients under treatment with antibiotics during inclusion could switch to treatment with penicillins immediately after testing, in line with the national recommendations for antibiotic use. Conclusions The prevalence of self-reported penicillin allergy was lower in this Norwegian population, than reported in other studies. Screening and testing of hospitalized patients with self-reported penicillin allergy is a feasible and easy measure to de-label a large proportion of patients, resulting in immediate clinical and environmental benefit. Our findings suggest that non-allergist physicians can safely undertake clinically impactful allergy evaluations.

Abstract
Purpose Reported antibiotic use in coronavirus disease 2019 (COVID-19) is far higher than the actual rate of reported bacterial co- and superinfection. A better understanding of antibiotic therapy in COVID-19 is necessary. Methods 6457 SARS-CoV-2-infected cases, documented from March 18, 2020, until February 16, 2021, in the LEOSS cohort were analyzed. As primary endpoint, the correlation between any antibiotic treatment and all-cause mortality/progression to the next more advanced phase of disease was calculated for adult patients in the complicated phase of disease and procalcitonin (PCT) ≤ 0.5 ng/ml. The analysis took the confounders gender, age, and comorbidities into account. Results Three thousand, six hundred twenty-seven cases matched all inclusion criteria for analyses. For the primary endpoint, antibiotic treatment was not correlated with lower all-cause mortality or progression to the next more advanced (critical) phase (n = 996) (both p > 0.05). For the secondary endpoints, patients in the uncomplicated phase (n = 1195), regardless of PCT level, had no lower all-cause mortality and did not progress less to the next more advanced (complicated) phase when treated with antibiotics (p > 0.05). Patients in the complicated phase with PCT > 0.5 ng/ml and antibiotic treatment (n = 286) had a significantly increased all-cause mortality (p = 0.029) but no significantly different probability of progression to the critical phase (p > 0.05). Conclusion In this cohort, antibiotics in SARS-CoV-2-infected patients were not associated with positive effects on all-cause mortality or disease progression. Additional studies are needed. Advice of local antibiotic stewardship- (ABS-) teams and local educational campaigns should be sought to improve rational antibiotic use in COVID-19 patients.

Abstract
An internet questionnaire survey for investigating empirical antibiotic usage and bacterial superinfections in patients with coronavirus disease-2019 (COVID-19) in Japan was conducted among the chief physicians of respiratory disease departments of 715 Japanese Respiratory Society-certified hospitals using Google Forms between January 28, 2021 and February 28, 2021. Responses to the questionnaire survey were obtained from 198 of 715 hospitals (27.6%). The survey revealed that the complication incidences of community-acquired pneumonia; hospital-acquired pneumonia, including ventilator-associated pneumonia; and sepsis were 2.86, 5.59, and 0.99%, respectively, among patients with moderate/severe and critical COVID-19. Bacterial co-infection and secondary infection rarely affected patients with COVID-19 in Japan, and the isolated pathogens were not specific to these patients. Moreover, the anti-inflammatory effects of macrolides for COVID-19 were not observed in several studies. These results might be useful in clinical practice for COVID-19.

INHALE: the impact of using FilmArray Pneumonia Panel molecular diagnostics for hospital-acquired and ventilator-associated pneumonia on antimicrobial stewardship and patient outcomes in UK Critical Care-study protocol for a multicentre randomised controlled trial. Trials 2021; 22:680. [PMID: 34620213 PMCID: PMC8496625 DOI: 10.1186/s13063-021-05618-6] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2020] [Accepted: 09/13/2021] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND Hospital-acquired and ventilator-associated pneumonias (HAP and VAP) are common in critical care and can be life-threatening. Rapid microbiological diagnostics, linked to an algorithm to translate their results into antibiotic choices, could simultaneously improve patient outcomes and antimicrobial stewardship. METHODS The INHALE Randomised Controlled Trial is a multi-centre, parallel study exploring the potential of the BioFire FilmArray molecular diagnostic to guide antibiotic treatment of HAP/VAP in intensive care units (ICU); it identifies pathogens and key antibiotic resistance in around 90 min. The comparator is standard care whereby the patient receives empirical antibiotics until microbiological culture results become available, typically after 48-72 h. Adult and paediatric ICU patients are eligible if they are about to receive antibiotics for a suspected lower respiratory infection (including HAP/VAP) for the first time or a change in antibiotic because of a deteriorating clinical condition. Breathing spontaneously or intubated, they must have been hospitalised for 48 h or more. Patients are randomised 1:1 to receive either antibiotics guided by the FilmArray molecular diagnostic and its trial-based prescribing algorithm or standard care, meaning empirical antibiotics based on local policy, adapted subsequently based upon local microbiology culture results. Co-primary outcomes are (i) non-inferiority in clinical cure of pneumonia at 14 days post-randomisation and (ii) superiority in antimicrobial stewardship at 24 h post-randomisation (defined as % of patients on active and proportionate antibiotics). Secondary outcomes include further stewardship reviews; length of ICU stay; co-morbidity indicators, including septic shock, change in sequential organ failure assessment scores, and secondary pneumonias; ventilator-free days; adverse events over 21 days; all-cause mortality; and total antibiotic usage. Both cost-effectiveness of the molecular diagnostic-guided therapy and behavioural aspects determining antibiotic prescribing are being explored. A sample size of 552 will be required to detect clinically significant results with 90% power and 5% significance for the co-primary outcomes. DISCUSSION This trial will test whether the potential merits of rapid molecular diagnostics for pathogen and resistance detection in HAP/VAP are realised in patient outcomes and/or improved antibiotic stewardship.

Abstract
BACKGROUND Point-of-care tests could be essential in differentiating bacterial and viral acute community-acquired lower respiratory tract infections and driving antibiotic stewardship in the community. OBJECTIVES To assess diagnostic test accuracy of point-of-care tests in community settings for acute community-acquired lower respiratory tract infections. DATA SOURCES Multiple databases (MEDLINE, EMBASE, Web of Science, Cochrane Library, Open Gray) from inception to 31 May 2021, without language restrictions. STUDY ELIGIBILITY CRITERIA Diagnostic test accuracy studies involving patients at primary care, outpatient clinic, emergency department and long-term care facilities with a clinical suspicion of acute community-acquired lower respiratory tract infections. The comparator was any test used as a comparison to the index test. In order not to limit the study inclusion, the comparator was not defined a priori. ASSESSMENT OF RISK OF BIAS Four investigators independently extracted data, rated risk of bias, and assessed the quality using QUADAS-2. METHODS OF DATA SYNTHESIS The measures of diagnostic test accuracy were calculated with 95% CI. RESULTS A total of 421 studies addressed at least one point-of-care test. The diagnostic performance of molecular tests was higher compared with that of rapid diagnostic tests for all the pathogens studied. The accuracy of stand-alone signs and symptoms or biomarkers was poor. Lung ultrasound showed high sensitivity and specificity (90% for both) for the diagnosis of bacterial pneumonia. Rapid antigen-based diagnostic tests for influenza, respiratory syncytial virus, human metapneumovirus, and Streptococcus pneumoniae had sub-optimal sensitivity (range 49%-84%) but high specificity (>80%). DISCUSSION Physical examination and host biomarkers are not sufficiently reliable as stand-alone tests to differentiate between bacterial and viral pneumonia. Lung ultrasound shows higher accuracy than chest X-ray for bacterial pneumonia at emergency department. Rapid antigen-based diagnostic tests cannot be considered fully reliable because of high false-negative rates. Overall, molecular tests for all the pathogens considered were found to be the most accurate.

Theodorou CM, Stokes SC, Hegazi MS, Brown EG, Saadai P. Is Pseudomonas infection associated with worse outcomes in pediatric perforated appendicitis? J Pediatr Surg 2021; 56:1826-1830. [PMID: 33223225 PMCID: PMC8096855 DOI: 10.1016/j.jpedsurg.2020.10.031] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/14/2020] [Revised: 10/11/2020] [Accepted: 10/28/2020] [Indexed: 11/18/2022]
Abstract
BACKGROUND There is little information on the effects of Pseudomonas infection on outcomes in perforated appendicitis. As Pseudomonas is not covered by many empiric appendicitis antibiotic regiments, we hypothesized that children with Pseudomonas would have worse outcomes. METHODS Patients <18 years old undergoing appendectomy for perforated appendicitis at a tertiary children's hospital 2015-2019 were included and were stratified by presence of Pseudomonas on intraoperative culture. The primary outcome was post-operative organ-space infection (SSI). RESULTS Intraoperative cultures were collected in 58.4% of patients (n = 149/255) with 22.2% (n = 33) positive for Pseudomonas. SSIs occurred in 21.2% of children with Pseudomonas compared to 20.7% of children without Pseudomonas (p = 0.9). Children with Pseudomonas had longer antibiotic duration (9.1 vs. 6.7 days, p = 0.03) and LOS (6.7 vs. 5.9 days, p = 0.03) than those without, but a similar rate of post-operative interventions (12.2% vs. 19.0%, p = 0.4), hospital costs ($28,860 vs. $23,945, p = 0.3), ED visits (9.1% vs. 19.9%, p = 0.3), and readmissions (9.1% vs. 9.5%, p = 1). CONCLUSION Pseudomonas was identified in 22% children with perforated appendicitis and was associated with longer antibiotic durations and LOS, but similar rates of SSI, post-operative interventions, and readmissions compared to children without Pseudomonas. Empiric coverage of Pseudomonas may not be necessary.

Abstract
BACKGROUND Administration of antibiotics within an hour of incision is a common quality metric for reduction of surgical site infections (SSI). Many pediatric patients who undergo surgery for an acute intraabdominal infection are already receiving treatment antibiotics. For these patients, we hypothesized that additional prophylactic antibiotic coverage would not decrease rates of SSI. METHODS Single institution retrospective review of patients <18 years old undergoing appendectomy or cholecystectomy 7/2014-7/2019. Patients were categorized based on administration of an additional prophylactic antibiotic to cover gram positive bacteria within an hour of incision. The primary outcome was SSI. Secondary outcomes were Clostridium difficile colitis, intraoperative allergic reaction and readmission within 30 days due to infection. RESULTS Of 363 patients, 261 received pre-operative prophylactic antibiotics and 92 received treatment antibiotics only. There was no difference in rates of organ space SSI (4.3% no prophylaxis vs 4.4% prophylaxis, p = 0.97) or superficial SSI (1.1% no prophylaxis vs. 0.7% prophylaxis, p>0.999). One patient who received prophylactic antibiotics was readmitted on post-operative day 29 with C. difficile colitis. There was no difference in rates of intraoperative allergic reaction or readmission. CONCLUSION In pediatric patients receiving treatment antibiotics for acute intraabdominal infection, additional prophylactic antibiotics may not reduce SSIs.

Problems associated with the use of the term "antibiotics". Naunyn Schmiedebergs Arch Pharmacol 2021; 394:2153-2166.

Abstract
The term “antibiotics” is a broadly used misnomer to designate antibacterial drugs. In a recent article, we have proposed to replace, e.g., the term “antibiotics” by “antibacterial drugs”, “antibiosis” by “antibacterial therapy”, “antibiogram” by “antibacteriogram”, and “antibiotic stewardship” by “antibacterial stewardship” (Seifert and Schirmer Trends Microbiol, 2021). In the present article, we show that many traditional terms related to antibiotics are used much more widely in the biomedical literature than the respective scientifically precise terms. This practice should be stopped. Moreover, we provide arguments to end the use of other broadly used terms in the biomedical literature such as “narrow-spectrum antibiotics” and “reserve antibiotics”, “chemotherapeutics”, and “tuberculostatics”. Finally, we provide several examples showing that antibacterial drugs are used for non-antibacterial indications and that some non-antibacterial drugs are used for antibacterial indications now. Thus, the increasing importance of drug repurposing renders it important to drop short designations of drug classes such as “antibiotics”. Rather, the term “drug” should be explicitly used, facilitating the inclusion of newly emerging indications such as antipsychotic and anti-inflammatory. This article is part of an effort to implement a new rational nomenclature of drug classes across the entire field of pharmacology.

Abstract
Patients increasingly receive care from a large spectrum of different settings, placing them at risk for exposure to pathogens by many different sources. Each health care environment has its own specific challenges, and thus infection control programs must be tailored to each specific setting. High-turnover outpatient settings may require additional considerations, such as establishing patient triage and follow-up protocols, and broadened cleaning and disinfection procedures. In nursing homes, infection control programs should focus on surveillance for infections and antimicrobial resistance, outbreak investigation and control plan for epidemics, isolation precautions, hand hygiene, staff education, and employee and resident health programs.

Abstract
BACKGROUND Urine examination has relevance for treatment, and reliability of positive urine culture (UC) is of importance. The technique of urine sampling (US), storage, and transportation is important. The objective of this study was to investigate if detailed patient information for the technique of US and hygiene reduces rates of contaminated UC in screened male patients, as this group was not investigated yet. METHODS All patients independently of complaints were enrolled prospectively and consecutively in an outpatient setting in 2 groups - the first group did not receive detailed information and the second group did. We examined 372 consecutive patients in 2017, 190 not receiving (median age 69 years) and 182 receiving information (median age 70 years), with comparable numbers of patients and age. The result of UC and age was imposed. RESULTS In all,74.2% of preclarification UC showed a contamination (n = 95) and 75.5% after clarification (n = 83), without significant differences (p = 0.827). This study is limited by the fact that adherence could not be checked. CONCLUSIONS Similar to studies with females, no difference occurred in rates of contaminated UC, so detailed information regarding the US technique does not decrease rates of contaminated UC and vice versa does not increase the quality of midstream-sampled UC in male patients.

Abstract
BACKGROUND Consumption of antibiotics active against meticillin-resistant Staphylococcus aureus (MRSA) has been described in numerous European studies. However, the underlying predictors of consumption are still poorly understood. AIM To describe the consumption of anti-MRSA antibiotics (daptomycin, intravenous glycopeptides, linezolid) in Switzerland over time and to identify underlying predictor variables. METHODS A retrospective observational multi-centre study was conducted in 21 Swiss hospitals over a period of 11 years (2009-2019). Multiple linear regression models were built to identify regional and hospital-specific predictor variables affecting the consumption of anti-MRSA antibiotics. FINDINGS Consumption of anti-MRSA antibiotics increased between 2009 and 2019 from 12.7 to 24.5 defined daily doses per 1000 bed-days (+93%). In the first model presented, which includes data of the whole study period, the following variables were associated with higher anti-MRSA antibiotic consumption: number of MRSA cases (P < 0.01), year (P < 0.01), hospital type (tertiary care university hospitals vs others, P < 0.01), hospital department (intensive care unit vs others, P < 0.01) and linguistic region (French vs German and German vs Italian, P < 0.01). In a second model including data from a query on hospital policies in place in 2019, the presence of an antibiotic stewardship group (P < 0.01) and prescription restrictions (P < 0.01) were associated with consumption of anti-MRSA antibiotics. CONCLUSION Our study shows that both the presence of an antibiotic stewardship group and the implementation of prescription restrictions, i.e. factors that can be controlled by the hospital itself, were associated with a lower consumption of anti-MRSA antibiotics.

Abstract
Antimicrobial therapy in terminally ill patients remains controversial as goals of care tend to be focused on optimizing comfort. International guidelines recommend for antibiotic stewardship program (ASP) involvement in antibiotic decisions in palliative patients. The primary objective was to evaluate the clinical impact of ASP interventions made to stop broad-spectrum intravenous antibiotics in terminally ill patients. This was a retrospective chart review of 459 terminally ill patients in Singapore General Hospital audited by ASP between December 2010 and December 2018. Antibiotic duration, time-to-terminal discharge for end-of-life care, time-to-mortality, and mortality rates of patients with antibiotics ceased or continued upon ASP recommendations were compared. A total of 283 and 176 antibiotic courses were ceased and continued post-intervention, respectively. The intervention acceptance rate was 61.7%. The 7-day mortality rate (47.3% vs 61.9%, p = 0.003) was lower in the ceased group, while 30-day mortality rate (76.0% vs 81.2%, p = 0.203) and time-to-mortality post-intervention (3 [0-24] vs 2 [0-27] days, p = 0.066) did not differ between the ceased and continued groups. After excluding the 57 patients who had antibiotics continued until death within 48 h of intervention, only time-to-mortality post-intervention was statistically significantly shorter in the ceased group (3 [0-24] vs 4 [0-27], p < 0.001). Of the 131 terminally discharged patients, antibiotic duration (4 [0-17] vs 6.5 [1-14] days, p = 0.001) and time-to-terminal discharge post-intervention (6 [0-74] vs 10.5 [3-63] days, p = 0.001) were shorter in the ceased group. Antibiotic cessation in terminally ill patients was safe, and was associated with a significantly shorter time-to-terminal discharge.

[PMID: 34412692 PMCID: PMC8377884 DOI: 10.1186/s41256-021-00216-0] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2020] [Accepted: 06/28/2021] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Antibiotic resistance is a major problem in every region of the globe and Sub-Saharan Africa (SSA) is no exception. Several systematic reviews have addressed the prevalence of resistant organisms but few have examined the underlying causes in this region. This systematic review of qualitative literature aims to highlight barriers and facilitators to antimicrobial stewardship in SSA. METHODS A literature search of Embase and MEDLINE(R) was carried out. Studies were included if they were in English, conducted in SSA, and reported qualitative data on the barriers and facilitators of antimicrobial stewardship or on attitudes towards resistance promoting behaviours. Studies were screened with a simple critical appraisal tool. Secondary constructs were extracted and coded into concepts, which were then reviewed and grouped into themes in light of the complete dataset. RESULTS The literature search yielded 169 results, of which 14 studies from 11 countries were included in the final analysis. No studies were excluded as a result of the critical appraisal. Eight concepts emerged from initial coding, which were consolidated into five major themes: ineffective regulation, health system factors, clinical governance, patient factors and lack of resources. The ineffective regulation theme highlighted the balance between tightening drugstore regulation, reducing over-the-counter sale of antibiotics, and maintaining access to medicines for rural communities. Meanwhile, health system factors explored the tension between antimicrobial stewardship and the need of pharmacy workers to maintain profitable businesses. Additionally, a lack of resources, actions by patients and the day-to-day challenges of providing healthcare were shown to directly impede antimicrobial stewardship and exacerbate other factors which promote resistance. CONCLUSION Antibiotic resistance in SSA is a multi-faceted issue and while limited resources contribute to the problem they should be viewed in the context of other factors. We identify several contextual factors that affect resistance and stewardship that should be considered by policy makers when planning interventions. This literature base is also incomplete, with only 11 nations accounted for and many studies being confined to regions within countries, so more research is needed. Specifically, further studies on implementing stewardship interventions, successful or not, would be beneficial to inform future efforts.

Efficacy and safety of discontinuing antibiotic treatment for uncomplicated respiratory tract infections when deemed unnecessary. A multicentre, randomized clinical trial in primary care. Clin Microbiol Infect 2021; 28:241-247. [PMID: 34363942 DOI: 10.1016/j.cmi.2021.07.035] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2021] [Revised: 07/25/2021] [Accepted: 07/26/2021] [Indexed: 12/27/2022]
Abstract
OBJECTIVES To determine the benefits and harms of discontinuing unnecessary antibiotic therapy for uncomplicated respiratory tract infections (RTI) when antibiotics are considered no longer necessary. METHODS Multicentre, open-label, randomized controlled clinical trial in primary care centres from 2017 to 2020 (ClinicalTrials.gov, NCT02900820). Adults with RTIs-acute rhinosinusitis, sore throat, influenza or acute bronchitis-who had previously taken any dose of antibiotic for less than 3 days, which physicians no longer deemed necessary were recruited. The patients were randomly assigned in a 1:1 ratio to discontinuing antibiotic therapy or the usual strategy of continuing antibiotic treatment. The primary outcome was the duration of severe symptoms (number of days scoring 5 or 6 on a six-item Likert scale). Secondary outcomes included days with symptoms, moderate symptoms (scores of 3 or 4), antibiotics taken, adverse events, patient satisfaction and complications within the first 3 months. RESULTS A total of 467 patients were randomized, out of which 409 were considered valid for the analysis. The mean (SD) duration of severe symptoms was 3.0 (1.5) days for the patients assigned to discontinuation and 2.8 (1.3) days for those allocated to the control group (mean difference 0.2 days; 95% CI -0.1 to 0.4 days). Patients randomized to the discontinuation group used fewer antibiotics after the baseline visit (52/207 (25.1%) versus 182/202 (90.1%); p 0.001). Patients assigned to antibiotic continuation presented a relative risk of adverse events of 1.47 (95% CI 0.80-2.71), but the need for further health-care contact in the following 3 months was slightly lower (RR 0.61; 95% CI 0.28-1.37). CONCLUSIONS Discontinuing antibiotic treatment for uncomplicated RTIs when clinicians consider it unnecessary is safe and notably reduces antibiotic consumption.

[PMID: 33524451 DOI: 10.1016/j.ajic.2021.01.018] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2020] [Revised: 01/19/2021] [Accepted: 01/20/2021] [Indexed: 01/21/2023]
Abstract
BACKGROUND Advanced practice providers in the outpatient setting play a key role in antibiotic stewardship, yet little is known about how to engage these providers in stewardship activities and what factors influence their antibiotic prescribing practices. METHODS We used mixed methods to obtain data on practices and perceptions related to antibiotic prescribing by nurse practitioners (NP) and Veteran patients. We interviewed NPs working in the outpatient setting at one Veterans Affairs facility and conducted focus groups with Veterans. Emerging themes were mapped to the Systems Engineering Initiative for Patient Safety framework. We examined NP antibiotic prescribing data from 2017 to 2019. RESULTS We interviewed NPs and conducted Veteran focus groups. Nurse practitioners reported satisfaction with resources, including ready access to pharmacists and infectious disease specialists. Building patient trust was reported as essential to prescribing confidence level. Veterans indicated the need to better understand differences between viral and bacterial infections. NP prescribing patterns revealed a decline in antibiotics prescribed for upper respiratory illnesses over a 3-year period. CONCLUSION Outpatient NPs focus on educating the patient while balancing organizational access challenges. Further research is needed to determine how to include both NPs and patients when implementing outpatient antibiotic stewardship strategies. Further research is also needed to understand factors associated with the decline in nurse practitioner antibiotic prescribing observed in this study.

Impact of a restrictive antibiotic policy on the acquisition of extended-spectrum beta-lactamase-producing Enterobacteriaceae in an endemic region: a before-and-after, propensity-matched cohort study in a Caribbean intensive care unit. CRITICAL CARE : THE OFFICIAL JOURNAL OF THE CRITICAL CARE FORUM 2021; 25:261. [PMID: 34311760 PMCID: PMC8311634 DOI: 10.1186/s13054-021-03660-z] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/30/2021] [Accepted: 06/27/2021] [Indexed: 12/29/2022]
Abstract
BACKGROUND High-level antibiotic consumption plays a critical role in the selection and spread of extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-E) in the ICU. Implementation of a stewardship program including a restrictive antibiotic policy was evaluated with respect to ESBL-E acquisition (carriage and infection). METHODS We implemented a 2-year, before-and-after intervention study including all consecutive adult patients admitted for > 48 h in the medical-surgical 26-bed ICU of Guadeloupe University Hospital (French West Indies). A conventional strategy period (CSP) including a broad-spectrum antibiotic as initial empirical treatment, followed by de-escalation (period before), was compared to a restrictive strategy period (RSP) limiting broad-spectrum antibiotics and shortening their duration. Antibiotic therapy was delayed and initiated only after microbiological identification, except for septic shock, severe acute respiratory distress syndrome and meningitis (period after). A multivariate Cox proportional hazard regression model adjusted on propensity score values was performed. The main outcome was the median time of being ESBL-E-free in the ICU. Secondary outcome included all-cause ICU mortality. RESULTS The study included 1541 patients: 738 in the CSP and 803 in the RSP. During the RSP, less patients were treated with antibiotics (46.8% vs. 57.9%; p < 0.01), treatment duration was shorter (5 vs. 6 days; p < 0.01), and administration of antibiotics targeting anaerobic pathogens significantly decreased (65.3% vs. 33.5%; p < 0.01) compared to the CSP. The incidence of ICU-acquired ESBL-E was lower (12.1% vs. 19%; p < 0.01) during the RSP. The median time of being ESBL-E-free was 22 days (95% CI 16-NA) in the RSP and 18 days (95% CI 16-21) in the CSP. After propensity score weighting and adjusted analysis, the median time of being ESBL-E-free was independently associated with the RSP (hazard ratio, 0.746 [95% CI 0.575-0.968]; p = 0.02, and hazard ratio 0.751 [95% CI 0.578-0.977]; p = 0.03, respectively). All-cause ICU mortality was lower in the RSP than in the CSP (22.5% vs. 28.6%; p < 0.01). CONCLUSIONS Implementation of a program including a restrictive antibiotic strategy is feasible and is associated with less ESBL-E acquisition in the ICU without any worsening of patient outcome.

Abstract
INTRODUCTION This study aims to assess the current epidemiology and microbiology of perforated appendicitis, how antibiotic choice and duration correlate with meaningful clinical outcomes, and whether serial white blood cell (WBC) counts provide clinical value. METHODS Five-year retrospective cohort study, 2015-2019, among 333 consecutive children, ages 0-18 years, treated at St. Louis Children's Hospital for perforated appendicitis. Main outcomes included length of stay (LOS), postoperative abscess formation, and readmission. Statistical analysis was performed with uni- and multi-variate analyses. RESULTS Intra-abdominal cultures most commonly grew Bacteroides fragilis (52%) and Escherichia coli (50%). Patients who initially received broad-spectrum antibiotics (meropenem, piperacillin-tazobactam, fourth-generation cephalosporins) for perforated appendicitis had greater rates of postoperative abscess formation (25% vs. 12%, p < 0.01) and LOS (7.0 vs. 5.7 days, p < 0.01). Similarly, antibiotics at time of discharge were associated with greater postoperative abscess formation (22% vs. 9%, p < 0.01) and LOS (6.4 vs. 5.6 days, p = 0.02). However, discharge with strictly oral antibiotics was not correlated with greater LOS, postoperative abscess formation, or readmission rates compared to discharge without antibiotics. Serial WBC counts had no predictive value for LOS, postoperative abscess formation, or readmission. CONCLUSIONS Bacteroides fragilis and E. coli were the most common intra-abdominal microbes for perforated appendicitis among our cohort. In non-critically ill children, the routine use of broad-spectrum antibiotics or continuation of antibiotics beyond discharge was not correlated with improved clinical outcomes. Additionally, WBC counts were not correlated with meaningful clinical outcomes.

Abstract
BACKGROUND Febrile neutropenia (FN) is an important oncological emergency seen in the emergency department (ED), and the American Society of Clinical Oncology recommends risk stratification of patients with febrile neutropenia using the Multinational Association for Supportive Care in Cancer (MASCC) Index, with ED discharge on oral antibiotics recommended for low-risk patients. OBJECTIVES To determine the prevalence of FN neutropenia and medical system wide ED treatment guideline adherence. METHODS We performed a retrospective chart review of all patients with an ICD-10 confirmed diagnosis of FN from January 2016-2019at 13 affiliated EDs within one medical system. Only cancer/chemotherapy related FN were included. Following the MASCC guidelines, we used post-hoc calculations to classify patients as low/high-risk, and compared key clinical variables (mortality, blood culture positivity, interventions). RESULTS 203 patients were found to have FN. 97.9% (184/203) received broad spectrum antibiotics, including 92% of the low-risk group (60/65). All patients were admitted, and no observed in-hospital mortality was noted in the low-risk group, meanwhile 5.1% (7/138) of the high-risk group died. 14/203 patients had positive blood cultures, none in the low-risk group. CONCLUSION The prevalence of FN is low among 13 EDs that had almost 1.7 million ED visits over a 3-year period. Guideline compliance for low-risk FN was poor. All patients were admitted, and nearly all patients received IV fluids and IV antibiotics. Improving FN management to align with national guidelines represents an opportunity to improved ED care of patients with cancer by reducing unnecessary hospitalizations.

Abstract
Evidence supporting the use of antibiotic stewardship programs (ASP) is growing in a variety of healthcare settings for its association with improved patient outcomes, decreased resistance, and improved healthcare costs. There have been few studies supporting this evidence in long-term care facilities. This project involved a program evaluation of a long-term care facility's ASP for urinary tract infection (UTI) management. Improvement in appropriate diagnosing and antibiotic prescribing for UTI was noted, but no conclusions could be made regarding the effect on patient outcomes. The ASP was considered beneficial in this facility and highlighted areas for improvement, notably the need for sustained commitment by facility leadership and healthcare providers. Nurse practitioners are equipped with the skills necessary to assist facilities with education and implementation of systematic programs for judicious antibiotic prescribing.

A mandatory indication-registration tool in hospital electronic medical records enabling systematic evaluation and benchmarking of the quality of antimicrobial use: a feasibility study. Antimicrob Resist Infect Control 2021; 10:103. [PMID: 34217361 PMCID: PMC8254448 DOI: 10.1186/s13756-021-00973-0] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2021] [Accepted: 06/18/2021] [Indexed: 12/20/2022] Open
Abstract
Objectives Evaluation of the extent and appropriateness of antimicrobial use is a cornerstone of antibiotic stewardship programs, but it is time-consuming. Documentation of the indication at the moment of prescription might be more time-efficient. We investigated the real-life feasibility of mandatory documentation of the indication for all hospital antibiotic prescriptions for quality evaluation purposes. Methods A mandatory prescription-indication format was implemented in the Electronic Medical Record (EMR) of three hospitals using EPIC or ChipSoft HIX software. We evaluated the retrieved data of all antibiotics (J01) prescribed as empiric therapy in adult patients with respiratory tract infections (RTI) or urinary tract infections (UTI), from January through December 2017 in Hospital A, June through October 2019 in Hospital B and May 2019 through June 2020 in Hospital C. Endpoints were the accuracy of the data, defined as agreement between selected indication for the prescription and the documented indication in the EMR, as assessed by manually screening a representative sample of eligible patient records in the EMR of the three hospitals, and appropriateness of the prescriptions, defined as the prescriptions being in accordance with the national guidelines. Results The datasets of hospitals A, B and C contained 9588, 338 and 5816 empiric antibiotic prescriptions indicated for RTI or UTI, respectively. The selected indication was in accordance with the documented indication in 96.7% (error rate: 10/300), 78.2% (error rate: 53/243), and 86.9% (error rate: 39/298), respectively. A considerable variation in guideline adherence was seen between the hospitals for severe community acquired pneumonia (adherence rate ranged from 35.4 to 53.0%), complicated UTI (40.0–67.1%) and cystitis (5.6–45.3%). Conclusions After local validation of the datasets to verify and optimize accuracy of the data, mandatory documentation of the indication for antibiotics enables a reliable and time-efficient method for systematic registration of the extent and appropriateness of empiric antimicrobial use, which might enable benchmarking both in-hospital and between hospitals.

Abstract
Background Procalcitonin, a biomarker to adjudge the duration of antibiotic therapy in patients with sepsis. Materials and methods A prospective, randomized, controlled, interventional, single-center study was conducted in a mixed adult intensive care unit (ICU). In a nonblinded study, 90 adult patients admitted to the ICU with sepsis and septic shock were randomized into group P (group procalcitonin) and group C (group control). The duration of antibiotic therapy was decided based on serum procalcitonin levels for patients in group P versus standard treatment protocols in group C. A procalcitonin value of <0.01 ng/mL or a subsequent decline of >80% from the baseline was cutoff and chosen to stop the antibiotic therapy. The primary aim was to compare the duration of antibiotic therapy (in days) in the two groups. The secondary objective was to compare and assess the length of ICU stay, reinfection, secondary infection rate, readmission rate, and mortality among the groups. Results The mean duration of antibiotic therapy was significantly lesser in patients in group P (4.98 ± 2.56 vs 7.73 ± 3.06 days, p < 0.001). Patients in group C spent more days in ICU (8.80 ± 3.35 vs 5.98 ± 2.73 days, p < 0.001). The secondary infection rate was significantly higher in group C (26.7% vs 4.4%, p = 0.014). Readmission and mortality rates were comparable between the groups. Conclusion Serum procalcitonin-based algorithm in critically ill patients with sepsis could lead to a reduction in the duration of antibiotic therapy, ICU stay, and associated morbidities like secondary infection rates. It further promotes antibiotic stewardship without any adverse effects on the patient's outcome. How to cite this article Vishalashi SMG, Gupta P, Verma PK.

Abstract
BACKGROUND A spurious label of β-lactam allergy compromises antibiotic stewardship. Delabeling protocols based on direct challenges (ie, not preceded by allergy tests) can be applied in low-risk patients. OBJECTIVE This study aims at determining the significance of the characteristics of urticaria in the risk stratification for delabeling. METHODS The characteristics of urticarial eruptions that had occurred during therapeutic courses with a β-lactam, namely the time interval between the exposure and onset, the dose (first or subsequent) after which urticaria appeared, and the duration of the eruption, were correlated to the results of a systematic allergy workup (skin tests, specific IgE measurements, and challenges). Data from 410 patients enrolled in 3 allergy centers (Rome and Troina, Italy, and Antwerp, Belgium) were analyzed. A multivariable logistic regression was performed, which included appearance within 1 hour after the first dose and regression within 1 day: a model that can be summarized as the "1-1-1" urticaria criterion. RESULTS An urticarial eruption that had appeared within 1 hour after the first dose and had regressed within 1 day was more frequently reported in the group with a positive allergy workup, with odds ratios of 17 (95% confidence interval [CI]: 9-31), 11 (95% CI: 6-20), and 48 (95% CI: 14-157), respectively (P < .005). The 1-1-1 criterion displayed a sensitivity and specificity of 85%, and a negative predictive value and a positive predictive value of 80% and 90%, respectively. CONCLUSION Patients with urticaria meeting the 1-1-1 criterion should be considered at high risk and referred for an allergy workup with skin testing and specific IgE measurement before challenging.

Abstract
BACKGROUND Collaborative practice in healthcare has been recommended to improve the quality of antimicrobial stewardship interventions, a behavioral change in antimicrobial use. Insufficient knowledge regarding antibiotic resistance, the fear of complications from infections, and how providers perceive antibiotic use and resistance are likely to influence prescribing behavior. This study's objective was to identify the knowledge and belief healthcare professionals' differences about antibiotic stewardship. METHODS This cross-sectional survey study of three hospitals in the East Java province, Indonesia utilized a 43-item questionnaire to assess antimicrobial stewardship knowledge and belief. There were 12 knowledge questions (total possible score: 12) and 31 belief questions (total possible score: 155). The Kuder Richardson 20 (KR-20) and Cronbach alpha values of the questionnaire were 0.54 and 0.92, respectively. RESULTS Out of the 257 respondents, 19% (48/257) had a low scores of knowledge, and 39% (101/257) had low scores on belief about antibiotic stewardship (101/257). Most midwives had a low scores on knowledge (25/61) and low scores on belief (46/61). Respondents with high scores on belief were 17% (10/59) physicians, 15% (4/27) pharmacists, 8% (5/65) nurses, and 3% (2/61) midwives. CONCLUSION Among healthcare professionals, knowledge and belief differences concerning antibiotic stewardship vary widely. These differences will affect their capability, behavior, and contribution to the healthcare team collaboration and performance. Further studies are needed to evaluate the correlation between the level of inter-professional collaboration and the quality of the antibiotic stewardship implementation.

Abstract
BACKGROUND South Asia is a hotspot for antimicrobial resistance due largely to over-the-counter antibiotic sales for humans and animals and from a lack of policy compliance among healthcare providers. Additionally, there is high population density and high infectious disease burden. This paper describes the development of social and behavioural change communication (SBCC) to increase the appropriate use of antibiotics. METHODS We used formative research to explore contextual drivers of antibiotic sales, purchase, consumption/use and promotion among four groups: 1) households, 2) drug shop staff, 3) registered physicians and 4) pharmaceutical companies/medical sales representatives. We used formative research findings and an intervention design workshop with stakeholders to select target behaviours, prioritise audiences and develop SBCC messages, in consultation with a creative agency, and through pilots and feedback. The behaviour change wheel was used to summarise findings. RESULTS Workshop participants identified behaviours considered amenable to change for all four groups. Household members and drug shop staff were prioritised as target audiences, both of which could be reached at drug shops. Among household members, there were two behaviours to change: suboptimal health seeking and ceasing antibiotic courses early. Thus, SBCC target behaviours included: seek registered physician consultations; ask whether the medicine provided is an antibiotic; ask for instructions on use and timing. Among drug shop staff, important antibiotic dispensing practices needed to change. SBCC target behaviours included: asking customers for prescriptions, referring them to registered physicians and increasing customer awareness by instructing that they were receiving antibiotics to take as a full course. CONCLUSIONS We prioritised drug shops for intervention delivery to all drug shop staff and their customers to improve antibiotic stewardship. Knowledge deficits among these groups were notable and considered amenable to change using a SBCC intervention addressing improved health seeking behaviours, improved health literacy on antibiotic use, and provision of information on policy governing shops. Further intervention refinement should consider using participatory methods and address the impact on profit and livelihoods for drug shop staff for optimal compliance.
