European Society of Clinical Microbiology and Infectious Diseases (ESCMID) guidelines for Antimicrobial Stewardship in Emergency Departments (endorsed by European Association of Hospital Pharmacists)

ScopeThis ESCMID guideline provides evidence-based recommendations to support a selection of appropriate antibiotic use practices for patients seen in the emergency department (ED) and guidance for their implementation.The topics addressed in this guideline are: 1) Do biomarkers or rapid pathogen tests improve antibiotic prescribing and/or clinical outcomes? 2) Does taking blood cultures in common infectious syndromes improve antibiotic prescribing and/or clinical outcomes? 3) Does watchful waiting without antibacterial therapy or with delayed antibiotic prescribing reduce antibiotic prescribing without worsening clinical outcomes in patients with specific infectious syndromes? 4) Do structured culture follow-up programs in patients discharged from the ED with cultures pending improve antibiotic prescribing? MethodsAn expert panel was convened by ESCMID and the guideline chair. The panel selected in consensus the four most relevant AMS topics according to pre-defined relevance criteria. For each main question for the four topics, a systematic review was performed, including randomized controlled trials and observational studies. Both clinical outcomes as well as stewardship process outcomes related to antibiotic use were deemed relevant. The literature searches were conducted between May 2021 and March 2022. In April 2022, the panel members were formally asked to suggest additional studies that were not identified in the initial searches. Data were summarized in a meta-analysis if possible or otherwise summarized narratively. The certainty of the evidence was classified according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria. The guideline panel reviewed the evidence per topic critically appraising the evidence and formulated recommendations through a consensus-based process. The strength of the recommendations was classified as strong or weak. To substantiate the implementation process, implementation trials or observational studies describing facilitators/barriers for implementation were identified from the same searches and were summarized narratively. RecommendationsThe recommendations on the use of biomarkers and rapid pathogen diagnostic tests focus on the initiation of antibiotics in patients admitted through the ED. Their effect on the discontinuation or de-escalation of antibiotics during hospital stay was not reported, neither was their effect on hospital infection prevention and control practices. The recommendations on watchful waiting (i.e., withholding antibiotics with some form of follow-up) focus on specific infectious syndromes for which the primary care literature was also included. The recommendations on blood cultures focus on the indication in three common infectious syndromes in the ED explicitly excluding patients with sepsis or septic shock.Most recommendations are based on very-low- and low-certainty of evidence, leading to weak recommendations or, when no evidence was available, to best practice statements. Implementation of these recommendations needs to be adapted to the specific settings and circumstances of the ED. The scarcity of high-quality studies in the area of antimicrobial stewardship in the ED highlights the need for future research in this field.

Burden and frequency of viral testing of kidney and non-kidney transplant recipients.

Transplant patients are at risk of infections due to long-term immunosuppression contributing to morbidity and mortality in this population. Post-transplant testing guidelines were established to monitor and guide therapeutic interventions in transplant recipients. We hypothesize that there are gaps in adherence to the recommended frequency of laboratory testing in post-transplant patients. We analyzed national reference laboratory data to compare viral post-transplant infection (PTI) testing frequency with their respective published guidelines to understand patient uptake and compliance. We evaluated the ordering patterns, positivity rates, and frequency of molecular infectious disease tests (MIDTs). We included 345 patients with International Classification of Diseases (ICD)-10 codes for transplant (Z940-Z942, Z944, Z9481, Z9483, Z9484) with at least two tests (within 7 days) in January 2019 and at least one test in December 2020 to find patients in the post-transplant period. We analyzed two cohorts: kidney transplant recipients (KTRs; 40%) and non-KTR (60%) then followed them longitudinally for the study period. In KTR cohort, high-to-low proportion of ordered MIDT was blood BK virus (bBKV) followed by cytomegalovirus (CMV); in non-KTR cohort, CMV was followed by Epstein-Barr virus (EBV). KTR cohort positivity was highest for urine BK virus (uBKV; 58%) followed by EBV (46%), bBKV (40%), and CMV (31%). Non-KTR cohort positivity was highest for uBKV (64%), EBV (51%), CMV (30%), bBKV (8%), and adenovirus (7%). All patients were tested at progressively longer intervals from the date of the first post-transplant ICD-10-coded test. More than 40% of the KTR cohort were tested less frequently for EBV and bBKV, and more than 20% of the non-KTR cohort were tested for EBV less frequently than published guidelines 4 months after transplant. Despite regular testing, the results of MIDT testing for KTR and non-KTR patients in the post-transplant period are not aligned with published guidelines.IMPORTANCEGuidance for post-transplant infectious disease testing is established, however, for certain infections it allows for clinician discretion. This leads to transplant center policies developing their own testing/surveillance strategies based on their specific transplant patient population (kidney, stem cell, etc.). The Organ Procurement and Transplant Network (OPTN) has developed a strategic plan to improve and standardize the transplant process in the US to improve outcomes of living donors and recipients. Publishing national reference lab data on the testing frequency and its alignment with the recommended guidelines for post-transplant infectious diseases can inform patient uptake and compliance for these strategic OPTN efforts.

Screening and treatment of latent tuberculosis in patients with solid tumors and systemic cancer therapy.

Tuberculosis is one of the infectious diseases with greater morbidity and mortality worldwide. Cancer causes an important immunosuppression with increased risk of infections. There is an enlarged bidirectional incidence between tuberculosis and cancer, mainly due to latent tuberculosis. There is great discrepancy between recommendations for screening and prophylaxis of latent tuberculosis in patients with solid tumors and systemic cancer therapy among different medical societies and guidelines. Most infectious diseases guidelines recommend it, while most oncology guidelines do not. Patients with solid tumours generally have a limited life expectancy and a state of intermittent immunosuppression, resulting in a lower risk of tuberculosis reactivation than other riskypopulations. There is a lack of prospective and retrospective studies analysing the benefit of screening and prophylaxis in this population. The first step is to study the incidence of active tuberculosis in this population to estimate the real magnitude of the problem.

The history of the Japanese Society for Neuro-infectious Diseases: Foundation, objectives, and legacy.

The Japanese Research Group for Neuro-infectious Diseases was founded in August 1996, and by 2004 it had evolved into the Japanese Society for Neuro-infectious Diseases. The Society focuses on neuroinfectious conditions (e.g., encephalitis/encephalopathy, myelitis, and meningitis), providing a venue for academic presentations and exchanges. Clinical guidelines for major neurological infectious diseases are also published by the Society, in order to meet the social demands of each era. Although the threat of herpes simplex encephalitis has declined due to acyclovir's introduction, the frequency of encephalitis or peripheral neuropathy caused by varicella-zoster virus is increasing. In Japan, prion disease, human T-cell leukemia virus-1 (HTLV-1)-associated myelopathy (HAM), subacute sclerosing panencephalitis (SSPE), and progressive multifocal leukoencephalopathy (PML) are designated as intractable diseases. The incidence of prion disease is 1.8/1,000,000 individuals, with the sporadic type accounting for 80%. Prion disease is fatal, and effective medications are awaited. HAM's prevalence is ~3/100,000 individuals, with a male-to-female ratio of 1:2-3. HAM is common in western Japan, including Kyushu and Okinawa. The prevalence of PML is rising with the spread of both immunosuppressive therapy for transplantation and treatment for multiple sclerosis. From late 2019 through 2020, the world faced a global outbreak of coronavirus disease 2019 (COVID-19) due to virus mutations, and the threat of new mutations persists. Close attention should be paid to the emergence of new neurological infections that could arise from abnormal weather patterns and/or a decline in immune function due to aging.

Impact of Irrational Use of Antibiotics Among Patients in the Intensive Care Unit on Clinical Outcomes in Sudan.

Intensive Care Unit (ICU) is a specialized ward where critically ill patients are admitted to provide intensive health care Inappropriate antimicrobial therapy (AMT) and high mortality rates were documented in the ICU. The influence of irrational use of empiric antibiotics on clinical outcomes in ICU patients is not well studied in Sudan. This study aims to determine the rational use of antibiotics and its impact on clinical outcomes among ICU patients. Using data collection form, a retrospective longitudinal study was conducted among ICU patients at Omdurman Military Hospital, Khartoum State. Patients admitted from January 2019 to December 2019 were included in the study. Patients who stayed in ICU < 48 hr were excluded. Appropriateness of AMT is assessed using culture sensitivity test (CST) and the American Society of Infectious Diseases (IDSA) guideline. Among 102 patients, 54.9% male, one-third of patients developed nosocomial infections, 80.4% received empiric therapy with broad-spectrum antibiotics. The CST is done in 19%, and 43% patients are prescribed inappropriate AMT. Inappropriate AMT is associated with recurrent infections 38.4% (p=0.028) and high mortality 33.8% (p=0.014). Overall mortality rate 63.7% ICU patients. Elevated mortality in nosocomial 57.8%, decreased with inappropriate AMT in 21.6% patients. Significantly higher mortality rates 90.7% among uncontrolled infections (p<0.001), 80.6% nosocomial infections (p=0.001), and 76.7% renal compromised (p=0.002). Empirical AMT reduces the frequency of nosocomial infections, which has an impact on mortality. Inappropriate AMT is significantly associated with uncontrolled infections and lower mortality. Implementing a restrictive infectious control system and effective stewardship programs in hospital ICU wards is recommended.

Management of nonfermenting gram-negative infections: a critique of the guidelines.

In the present narrative review, we discuss the characteristics and differences between the Infectious Diseases Society of America (IDSA) and European Society of Clinical Microbiology and Infectious Diseases (ESCMID) guidelines in terms on their recommendations/suggestions for the treatment of Pseudomonas aeruginosa and Acinetobacter baumannii infections. Treatment of severe infections caused by nonfermenting gram-negative bacteria (NF-GNB) is posing both novel hopes and novel challenges to physicians worldwide, and both the IDSA and the ESCMID have recently updated/released their guidelines or guidance documents, based on different philosophies and providing recommendations for the treatment of NF-GNB infections. In order to correctly exploit recent advances in the treatment of such infections, IDSA and ESCMID approaches should be viewed as complementary and evolving, and should not preclude further revision based on accumulating evidence on the use of novel β-lactams and β-lactam/β-lactamase inhibitor combinations. A joint consideration of both philosophies should leave the door opened for the wise use of novel agents, ultimately building precious experience on their use that could favorably influence future guidelines revisions.

European society of Clinical Microbiology and Infectious Diseases guidelines on diagnosis and treatment of brain abscess in children and adults

ScopeThese European Society of Clinical Microbiology and Infectious Diseases guidelines are intended for clinicians involved in diagnosis and treatment of brain abscess in children and adults. MethodsKey questions were developed, and a systematic review was carried out of all studies published since 1 January 1996, using the search terms ‘brain abscess’ OR ‘cerebral abscess’ as Mesh terms or text in electronic databases of PubMed, Embase, and the Cochrane registry. The search was updated on 29 September 2022. Exclusion criteria were a sample size <10 patients or publication in non-English language. Extracted data was summarized as narrative reviews and tables. Meta-analysis was carried out using a random effects model and heterogeneity was examined by I2 tests as well as funnel and Galbraith plots. Risk of bias was assessed using Risk Of Bias in Non-randomised Studies - of Interventions (ROBINS-I) (observational studies) and Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2) (diagnostic studies). The Grading of Recommendations Assessment, Development and Evaluation approach was applied to classify strength of recommendations (strong or conditional) and quality of evidence (high, moderate, low, or very low). Questions addressed by the guidelines and recommendationsMagnetic resonance imaging is recommended for diagnosis of brain abscess (strong and high). Antimicrobials may be withheld until aspiration or excision of brain abscess in patients without severe disease if neurosurgery can be carried out within reasonable time, preferably within 24 hours (conditional and low). Molecular-based diagnostics are recommended, if available, in patients with negative cultures (conditional and moderate). Aspiration or excision of brain abscess is recommended whenever feasible, except for cases with toxoplasmosis (strong and low). Recommended empirical antimicrobial treatment for community-acquired brain abscess in immuno-competent individuals is a 3rd-generation cephalosporin and metronidazole (strong and moderate) with the addition of trimethoprim-sulfamethoxazole and voriconazole in patients with severe immuno-compromise (conditional and low). Recommended empirical treatment of post-neurosurgical brain abscess is a carbapenem combined with vancomycin or linezolid (conditional and low). The recommended duration of antimicrobial treatment is 6–8 weeks (conditional and low). No recommendation is offered for early transition to oral antimicrobials because of a lack of data, and oral consolidation treatment after ≥6 weeks of intravenous antimicrobials is not routinely recommended (conditional and very low). Adjunctive glucocorticoid treatment is recommended for treatment of severe symptoms because of perifocal oedema or impending herniation (strong and low). Primary prophylaxis with antiepileptics is not recommended (conditional and very low). Research needs are addressed.

South Asian Transplant Infectious Disease Guidelines for Solid Organ Transplant Candidates, Recipients, and Donors.

These guidelines discuss the epidemiology, screening, diagnosis, posttransplant prophylaxis, monitoring, and management of endemic infections in solid organ transplant (SOT) candidates, recipients, and donors in South Asia. The guidelines also provide recommendations for SOT recipients traveling to this region. These guidelines are based on literature review and expert opinion by transplant physicians, surgeons, and infectious diseases specialists, mostly from South Asian countries (India, Pakistan, Bangladesh, Nepal, and Sri Lanka) as well as transplant experts from other countries. These guidelines cover relevant endemic bacterial infections (tuberculosis, leptospirosis, melioidosis, typhoid, scrub typhus), viral infections (hepatitis A, B, C, D, and E; rabies; and the arboviruses including dengue, chikungunya, Zika, Japanese encephalitis), endemic fungal infections (mucormycosis, histoplasmosis, talaromycosis, sporotrichosis), and endemic parasitic infections (malaria, leishmaniasis, toxoplasmosis, cryptosporidiosis, strongyloidiasis, and filariasis) as well as travelers' diarrhea and vaccination for SOT candidates and recipients including travelers visiting this region. These guidelines are intended to be an overview of each topic; more detailed reviews are being published as a special supplement in the Indian Journal of Transplantation .

A cost-utility analysis of two Clostridioides difficile infection guideline treatment pathways

ObjectivesTreatment guidelines are key drivers of prescribing practice in the management of Clostridioides difficile infection (CDI), but recommendations on best practice can vary. We conducted a cost-utility analysis to compare the treatment pathway recommended by the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) guideline with the pathway proposed by the National Institute for Health and Care Excellence (NICE) guideline, from the perspective of the UK National Health Service. MethodsA decision tree modelling approach was adopted to reflect the treatment pathway for CDI as outlined in ESCMID and NICE guidelines. Patients experiencing a CDI infection received up to three treatments per infection to achieve a response and could subsequently experience up to two recurrences. Data on patient demographics, treatment response, recurrence, utilities, CDI-related mortality, and costs were taken from published literature. ResultsThe ESCMID treatment pathway was cost-effective versus the NICE treatment pathway at a threshold of £20 000 per quality-adjusted life year gained, with an incremental cost-effectiveness ratio of £4931. Cost-effectiveness was driven by differences in index infection recommendations (ESCMID recommends fidaxomicin as first-line treatment whereas NICE recommends vancomycin). The model results were robust to variations in inputs investigated in scenarios and sensitivity analyses, and probabilistic sensitivity analysis demonstrated that the ESCMID guideline treatment strategy had a 100% likelihood of being cost-effective versus the NICE treatment strategy. DiscussionCompared with the NICE guideline, the ESCMID guideline recommendations for treating an index CDI represent the most cost-effective use of healthcare resources from the perspective of the UK National Health Service.

Investigation of Upper Respiratory Carriage of Bacterial Pathogens among University Students in Kampar, Malaysia.

The carriage of bacterial pathogens in the human upper respiratory tract (URT) is associated with a risk of invasive respiratory tract infections, but the related epidemiological information on this at the population level is scarce in Malaysia. This study aimed to investigate the URT carriage of Streptococcus pneumoniae, Haemophilus influenzae, Neisseria meningitidis, Staphylococcus aureus, Klebsiella pneumoniae and Pseudomonas aeruginosa among 100 university students by nasal and oropharyngeal swabbing. The presence of S. aureus, K. pneumoniae and P. aeruginosa was assessed via swab culture on selective media and PCR on the resulting isolates. For S. pneumoniae, H. influenzae and N. meningitidis, their presence was assessed via multiplex PCR on the total DNA extracts from chocolate agar cultures. The carriage prevalence of H. influenzae, S. aureus, S. pneumoniae, K. pneumoniae, N. meningitidis and P. aeruginosa among the subjects was 36%, 27%, 15%, 11%, 5% and 1%, respectively, by these approaches. Their carriage was significantly higher in males compared to females overall. The S. aureus, K. pneumoniae and P. aeruginosa isolates were also screened by the Kirby-Bauer assay, in which 51.6% of S. aureus were penicillin-resistant. The outcomes from carriage studies are expected to contribute to informing infectious disease control policies and guidelines.

The relationship between depression, anxiety, e-health literacy, and health-promoting behavior in nursing students during COVID-19.

The purpose of this study was to identify the correlation between depression, anxiety, e-health literacy (eHL), and health-promoting behaviors among nursing students during the coronavirus disease 2019 (COVID-19) pandemic, and to identify the factors affecting health-promoting behaviors. A cross-sectional study was conducted online, recruiting 301 nursing students recruited from 4 universities in the Chungcheng Province and Daejeon Metropolitan City in South Korea between May 28 and June 30, 2021. Data were analyzed using SPSS WIN 27.0. The general characteristics of the study participants were analyzed by frequency and percentage, and the degree of depression, anxiety, eHL, and health-promoting behaviors were calculated as averages and standard deviations. Differences in health-promoting behaviors according to general characteristics were analyzed using independent t tests and analysis of variance, and a post hoc Scheffe test was conducted. Correlations between depression, anxiety, eHL, and health-promoting behaviors were measured using Pearson correlation matrices. Stepwise multiple regression was performed to identify factors affecting health-promoting behaviors. During the COVID-19 pandemic, the average level of depression and anxiety was reported to be 3.93 (4.71) and 3.40 (4.30), respectively; 33.2% of nursing students experienced more than mild depression and 29.2% experienced anxiety. The average eHL level was 3.91 (0.56), and the average of health-promoting behaviors was 2.43 (0.45). Depression was positively correlated with anxiety (R = 0.734, P < .001) and negatively correlated with health-promoting behaviors (r = -0.198, P = .001), whereas eHL had a positive correlation with health-promoting behaviors (R = 0.347, P < .001). The factors affecting health-promoting behaviors were religion (β = -0.160, standard error [SE] = 0.048), current health status (β = -0.097, SE = 0.032), frequency of searching the Internet for health-related information in a week (β = -0.070, SE = 0.026), interest in health (β = -0.191, SE = 0.039), and critical eHL (β = 0.243, SE = 0.040); the explanatory power was 27.4%. Results demonstrate that during the COVID-19 pandemic, higher depression and anxiety among nursing students decreased health-promoting behaviors, while higher eHL increased health-promoting behaviors, and eHL was a major factor affecting health-promoting behaviors. These results contribute to the provision of basic data for the development of nursing intervention programs and educational strategies that can establish correct health-promoting behaviors by managing depression and anxiety among nursing students and improving eHL.

Aetiologies of Central Nervous System Infections: A Study at Tertiary Care Hospital in Northern Punjab

Objective: To identify demographic patterns and etiologies of CNS infections and to identify the clinical presentations, diagnostic accuracy, and clinical outcomes of various CNS infections in hospitalized patients in a tertiary care hospital.&#x0D; Study Design: Cross sectional study.&#x0D; Place and Duration of Study: Pak Emirates Military Hospital, Rawalpindi Pakistan, from Oct 2019 to Jun 2020.&#x0D; Methodology: A total of 97 adult patients presenting with clinical features of Central Nervous System (CNS) infection were enrolled for this in-hospital study. Cerebrospinal fluid (CSF) was collected for a routine examination, bacterial culture, and viral Polymerase Chain Reaction (PCR) test. Human Immunodeficiency Virus (HIV) serology and neuroimaging were done in all cases. The diagnosis was established based on World Health Organization guidelines for infectious diseases. Infections were classified into four major categories for analysis purposes.&#x0D; Results: Of 97 enrolled patients, the mean age was 38.8±18.5 years. CNS tuberculosis was the most common infection seen in 46(47.4%) cases, 25(25.7%) patients had viral encephalitis, and 17(17.5%) had bacterial meningitis. The rest of the patients (n=9) had fungal (3%) or parasitic infections (4%). In contrast, two patients were found to have focal cerebritis, one due to Brucella and the other due to Salmonella typhi.&#x0D; Conclusion: Tuberculosis is the most common (CNS infection in this region. First, patients with CNS infections, especially chronic ones, present very late in our setting, leading to increased morbidity and mortality. Secondly, Molecular diagnosis is obtainable in only a small percentage of cases for various reasons.

1802. Off-label Use of Antimicrobial Agents at the University Hospital for Infectious Diseases, Zagreb, Croatia

Abstract Background Antimicrobial agents' (AMAs) off-label use can be associated with the prescriber's education. Little is known about the AMAs' off-label use by infectious disease (ID) specialists. We have conducted research at the University Hospital for Infectious Diseases (UHID), Zagreb, Croatia, a 230-bed tertiary center where ID specialists primarily prescribe AMAs. Methods A retrospective cross-sectional analysis was conducted on the day with the highest hospitalization number, January 17, 2019. Any use of AMA not complying with the SmPC was considered off-label and evaluated regarding modality (indication, dose, regimen, route of administration, and age) and justification by institutional or/and the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) guidelines. Results The study included 155 patients, 63 (40.6%) adults and 92 (59.4%) children. 61 (96.8%) adult patients had at least one AMA. There were 134 AMA prescriptions in adults, 42 (31.3%) off-label. AMAs were most frequently prescribed off-label regarding regimen (21), dose (17), and indication (14). Institutional guidelines justified off-label in 5 cases regarding dose, 4 regarding indication, and 2 regarding regimen. ESCMID guidelines justified off-label prescriptions in 5 cases regarding indication. The rest of the off-label was not supported by the existing guidelines. 60 (65.2%) pediatric patients had at least one AMA. There were 73 prescriptions, 31 (42.5%) off-label. AMAs were most frequently prescribed off-label regarding indication (19), dose (12), and age (2). Institutional guidelines justified 3 off-label cases regarding indication and 1 regarding dose. ESCMID guidelines justified no off-label in children. The lack of guidelines was the leading cause of the off-label AMAs use in children. Conclusion One-third of AMAs are prescribed off-label regarding SmPC by ID specialists. However, institutional and international guidelines can justify part of this use. Disclosures All Authors: No reported disclosures.

Investigating antibiotic use in Gaza Strip hospitals: A retrospective cross-sectional analysis.

Rates of antimicrobial resistance in the Gaza Strip are rising while regulations on antibiotics use are weakly implemented. This study aimed to investigate antibiotic use in hospitals utilizing World Health Organization (WHO) hospital, prescribing, and patient care indicators. A retrospective study was conducted at Al Shifa medical complex (SMC), Nasser Medical Complex (NMC), and European Gaza Hospital (EGH). Data for hospital indicators were collected from drug inventory records and by interviewing hospital pharmacy managers, while data for prescribing and patient care indicators were collected from medical records from all departments. WHO standard data collection forms and formulas to calculate quantitative indicators were used. Standard treatment guidelines for infectious diseases were unavailable. The availability of key antibiotics on the day of the investigation was 58.62%, 90.9%, and 44.82%, and antibiotics were out of stock for 120.5, 63.3, and 119.8 days/year in SMC, NMC, and EGH, respectively. A total of 1400 patients' records were screened; 68.2% of patients were prescribed antibiotics with an average duration of 3 days. The number of antibiotics prescribed was 1.26/hospitalization, 55% were prescribed by generic name, 98% were consistent with the essential medicine list, and 94.7% were given parenterally. Ceftriaxone was the most commonly used antibiotic (47.5%). Adherence rates to STGs for Caesarean section antibiotic prophylaxis and for pneumonia were 43% and 6.3%, respectively. About 97% of doses of prescribed antibiotics were administered and patients on antibiotics stayed in the hospital for 4.1 days. Antibiotic utilization patterns are less than optimal. Strategies to improve antibiotic use in the investigated hospitals are needed.

Safe prevention of Clostridium difficile using infectious disease guidelines at an urban hospital in North Carolina

"They Just Assume That We're All Going to Do the Wrong Thing With It. It's Just Not True": Stakeholder Perspectives About Peripherally Inserted Central Catheters in People Who Inject Drugs.

BackgroundIn the absence of adequate harm reduction opportunities, people who inject drugs (PWID) are at increased risk for serious infections. Infectious diseases guidelines recommend extended periods of intravenous antibiotic treatment through peripherally inserted central catheters (PICCs), but PWID are often deemed unsuitable for this treatment. We conducted semi-structured interviews and focus groups to understand the perspectives and opinions of patients and clinicians on the use of PICCs for PWID.MethodsWe approached patients and clinicians (doctors, nurses, PICC nurses, social workers, and case workers) involved in patient care at Tufts Medical Center (Boston, Massachusetts) between August 2019 and April 2020 for semi-structured interviews and focus groups.ResultsEleven of 14 (79%) patients agreed to participate in an in-depth interview, and 5 role-specific clinician focus groups (1 group consisting of infectious diseases, internal medicine, and addiction psychiatry doctors, 2 separate groups of floor nurses, 1 group of PICC nurses, and 1 group of social workers) were completed. Emergent themes included the overall agreement that PICCs improve healthcare, patients’ feelings that their stage of recovery from addiction was not taken into consideration, and clinicians’ anecdotal negative experiences driving decisions on PICCs.ConclusionsWhen analyzed together, the experiences of PWID and clinicians shed light on ways the healthcare system can improve the quality of care for PWID hospitalized for infections. Further research is needed to develop a system of person-centered care for PWID that meets the specific needs of patients and improves the relationship between them and the healthcare system.

European society of clinical microbiology and infectious diseases guidelines for coronavirus disease 2019: an update on treatment of patients with mild/moderate disease

ScopeDespite the large availability of vaccines, coronavirus disease 2019 (COVID-19), induced by severe acute respiratory syndrome coronavirus 2, continues to be a major threat for health-care providers and fragile people. A number of options are now available for outpatients with mild-to-moderate COVID-19 at the risk of disease progression for the prevention of deaths or hospitalization. MethodsA European Society of Clinical Microbiology and Infectious Diseases COVID-19 guidelines task force was established by the European Society of Clinical Microbiology and Infectious Diseases Executive Committee. A small group was established, half appointed by the chair and the remaining selected based on an open call. Each panel met virtually once a week. For all decisions, a simple majority vote was used. A long list of clinical questions using the population, intervention, comparison, outcome format was developed at the beginning of the process. For each population, intervention, comparison, outcome, two panel members performed a literature search, with a third panelist involved in case of inconsistent results. Voting was based on the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. RecommendationsIn this update, we focus on anti-viral agents, monoclonal antibodies (mAbs) and other treatment options proposed for patients with mild or moderate COVID-19 who are at the risk of hospitalization or death. Although the use of anti-virals is recommended, especially nirmatrelvir/ritonavir and remdesivir or, alternatively, molnupirarvir, the administration of mAbs against the spike protein strictly depends on circulating variants or the ability to test timely for variants and sub-variants. At the time of writing (April–June 2022), the only active mAb was tixagevimab/cilgavimab given the predominance of the Omicron BA.2, BA.3, BA.4 and BA.5 sub-lineages in Europe. However, considering that the epidemiological scenario is extremely dynamic, constant monitoring of variants of concern is mandatory.

Veterinary antimicrobial prescribing practices for treatment of presumptive sporadic urinary tract infections in dogs examined at primary care practices in the United States (2010-2019).

To describe patterns of antimicrobial prescriptions for sporadic urinary tract infections (UTIs) in dogs in the United States from 2010 through 2019, including times before and after publication of International Society for Companion Animal Infectious Disease (ISCAID) guidelines. 461,244 qualifying visits for sporadic UTIs. Veterinary electronic medical records of a private corporation consisting of > 1,000 clinics across the United States were examined to identify canine visits for potential sporadic UTI between January 1, 2010, and December 31, 2019. Proportions of antimicrobial prescriptions were graphed by month and year to identify changes in prescription patterns over time. Interrupted time series analysis was performed for the aminopenicillins. A total of 461,244 qualifying visits were examined, with 389,949 (85%) of these resulting in at least 1 antimicrobial prescription. Over the 10-year period, the proportion of visits resulting in no antimicrobial prescription increased (14% in 2010 to 19.7% in 2019). Proportions of prescriptions for amoxicillin (38% to 48%) and amoxicillin-clavulanic acid (2.5% to 10%) also increased. Log-linear regression supported that changes in proportions of amoxicillin and amoxicillin-clavulanic acid prescriptions occurred following the 2011 ISCAID guidelines publication, with the proportion of amoxicillin prescriptions increasing by 13% per year (95% CI, 12% to 14%; P < 0.01) and the proportion of amoxicillin-clavulanic acid prescriptions increasing by 0.5% per year (95% CI, 0.2% to 0.8%; P < 0.01). Use of fluoroquinolones and third-generation cephalosporins remained constant. Results suggest that efforts to guide antimicrobial use in veterinary clinical practice are having positive effects in this private veterinary company, though continued efforts are warranted.
