The Detection of Vancomycin in Sweat: A Next-Generation Digital Surrogate Marker for Antibiotic Tissue Penetration: A Pilot Study. Digit Biomark 2021; 5:24-28. [PMID: 33615119 PMCID: PMC7879282 DOI: 10.1159/000512947] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2020] [Accepted: 11/09/2020] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Assuring adequate antibiotic tissue concentrations at the point of infection, especially in skin and soft tissue infections, is pivotal for an effective treatment and cure. Despite the global issue, a reliable AB monitoring test is missing. Inadequate antibiotic treatment leads to the development of antimicrobial resistances and toxic side effects. β-lactam antibiotics were already detected in sweat of patients treated with the respective antibiotics intravenously before. With the emergence of smartphone-based biosensors to analyse sweat on the spot of need, next-generation molecular digital biomarkers will be increasingly available for a non-invasive pharmacotherapy monitoring. OBJECTIVE Here, we investigated if the glycopeptide antibiotic vancomycin is detectable in sweat samples of in-patients treated with intravenous vancomycin. METHODS Eccrine sweat samples were collected using the Macroduct Sweat Collector®. Along every sweat sample, a blood sample was taken. Bio-fluid analysis was performed by Ultra-high Pressure Liquid Chromatograph-Tandem Quadrupole Mass Spectrometry coupled with tandem mass spectrometry. RESULTS A total of 5 patients were included. Results demonstrate that vancomycin was detected in 5 out of 5 sweat samples. Specifically, vancomycin concentrations ranged from 0.011 to 0.118 mg/L in sweat and from 4.7 to 8.5 mg/L in blood. CONCLUSION Our results serve as proof-of-concept that vancomycin is detectable in eccrine sweat and may serve as a surrogate marker for antibiotic tissue penetration. A targeted vancomycin treatment is crucial in patients with repetitive need for antibiotics and a variable antibiotic distribution such as in peripheral artery disease to optimize treatment effectiveness. If combined with on-skin smartphone-based biosensors and smartphone applications, the detection of antibiotic concentrations in sweat might enable a first digital, on-spot, lab-independent and non-invasive therapeutic drug monitoring in skin and soft tissue infections.

Abstract
Antibiotic-resistant infections cause over 20 thousand deaths and $20 billion annually in the United States. Antibiotic prescribing decision making can be described as a "tragedy of the commons" behavioral economics problem, for which individual best interests affecting human decision-making lead to suboptimal societal antibiotic overuse. In 2015, the U.S. federal government announced a $1.2 billion National Action Plan to combat resistance and reduce antibiotic use by 20% in inpatient settings and 50% in outpatient settings by 2020. We develop and apply a behavioral economics model based on game theory and "tragedy of the commons" concepts to help illustrate why rational individuals may not practice ideal stewardship and how to potentially structure three specific alternate approaches to accomplish these objectives (collective cooperative management, usage taxes, resistance penalties), based on Ostrom's economic governance principles. Importantly, while each approach can effectively incentivize ideal stewardship, the latter two do so with 10-30% lower utility to all providers. Encouraging local or state-level self-managed cooperative stewardship programs thus is preferred to national taxes and penalties, in contrast with current trends and with similar implications in other countries.

[PMID: 33290816 DOI: 10.1016/j.jhin.2020.12.001] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2020] [Revised: 12/01/2020] [Accepted: 12/01/2020] [Indexed: 11/25/2022]
Abstract
BACKGROUND Carbapenem resistance in Gram-negative bacteria is associated with severe infections in the hospital setting. No uniform screening policy or agreed set of criteria exists within the EU to inform treatment decisions for infections caused by carbapenem-resistant Gram-negative bacteria. AIM To develop a range of consensus statements to survey experts in carbapenem resistance, to identify potential similarities and differences across the EU and across specialties. METHODS The survey contained 43 statements, covering six key topics relating to carbapenem-resistant organisms: microbiological screening; diagnosis; infection control implementation; antibiotic stewardship; use of resources; and influencing policy. FINDINGS In total, 136 survey responses were received (66% infectious disease specialists, 18% microbiologists, 11% intensive care specialists, 4% other/unknown) from France, Germany, Greece, Italy, Spain, and the UK. High, or very high, levels of agreement were seen for all 43 consensus statements, indicating good alignment concerning early identification and optimal management of infection due to carbapenem-resistant organisms. CONCLUSION We offer the following recommendations: (1) screening is required when a patient may have been exposed to the healthcare system in countries/hospitals where carbapenem-resistant organisms are endemic; (2) rapid diagnostic tools should be available in every institution; (3) all institutions should have a specific policy for the control of carbapenem-resistant organisms, which is routinely audited; (4) clear strategies are required to define both appropriate and inappropriate use of carbapenems; (5) priority funding should be allocated to the management of infections due to carbapenem-resistant organisms; and (6) international co-operation is required to reduce country-to-country transmission of carbapenem-resistant organisms.

Abstract
OBJECTIVES Vancomycin-resistant E. faecium (VRE) is a common cause of healthcare-associated infections. The emergence of VRE with tigecycline resistance (TVRE) is increasing but its impact on patient outcome is still not well defined. This study aimed to assess risk factors for the acquisition of TVRE and of patient outcomes associated with TVRE carriage/infection. METHODS At the University Hospital Frankfurt, we conducted a matched pair TVRE-VRE analysis to identify risk factors for TVRE carriage. Bed-to-bed contacts and potential transmission routes were reconstructed. TVRE were whole-genome sequenced to confirm suspected transmission events and to identify tigecycline resistance mechanisms. RESULTS 76 TVRE cases were identified between 02/2014-04/2017 and compared to VRE colonized or infected controls. TVRE carriage was associated with exposure to tigecycline, an increased rate of bloodstream infections (BSI) with VRE or Candida spp., and higher mortality. Whole-genome sequencing-based analysis of 24 TVRE provided evidence for transmissions of TVRE, also across different wards. CONCLUSIONS Tigecycline exposure is the main risk factor for TVRE carriage. VRE/TVRE- and Candida-BSI are associated with worse clinical outcome. Hospital transmission of TVRE may occur despite strict contact precautions, whereas both antimicrobial stewardship and infection control interventions are of high importance to prevent emergence and spread of TVRE.

Abstract
BACKGROUND Nurses are key in implementing antibiotic stewardship; however, standardized processes are lacking. METHODS This feasibility study tested implementation of a nurse-driven antibiotic engagement tool (AET) that addressed antibiotic indication, duration, discontinuation, and intravenous to oral conversion. An investigator-developed survey measured nurse satisfaction, confidence, and understanding of antibiotic plan of care among 4 clinical units. Mann-Whitney U was used to compare differences between time periods. Nonparametric summary distributions assessed AET use. RESULTS Results from 121 surveys were available; 71 (36%) presurvey, 50 (24%) postsurvey. Thirteen registered nurses reported satisfaction or agreement with AET use: (1) ease (median: 4 [2.25, 4]); (2) time (median: 4 [3.5, 4.5]); (3) helped facilitate asking questions (median: 4 [3, 4]); (4) helped find antibiotic information (median: 4 [2.5, 4]); and (5) increased confidence in antibiotic discussions (median 4 [3, 4]). Planned duration of antibiotic therapy was unclear to nurses 13.9% of the time with nurses identifying duration discrepancies in 22.8% of submitted AETs. CONCLUSIONS The AET promoted interprofessional conversation. Use was higher in settings where leaders and nurse influencers were involved in stewardship promotion. Clarifying antibiotic duration is a prime area for future nursing antibiotic stewardship efforts.

Abstract
BACKGROUND Concern regarding bacterial co-infection complicating SARS-CoV-2 has created a challenge for antimicrobial stewardship. Following introduction of national antibiotic recommendations for suspected bacterial respiratory tract infection complicating COVID-19, a point prevalence survey of prescribing was conducted across acute hospitals in Scotland. METHODS Patients in designated COVID-19 units were included and demographic, clinical and antimicrobial data were collected from 15 hospitals on a single day between 20th and 30th April 2020. Comparisons were made between SARS-CoV-2 positive and negative patients and patients on non-critical care and critical care units. Factors associated with antibiotic prescribing in SARS-CoV-2 positive patients were examined using Univariable and multivariable regression analyses. FINDINGS There were 820 patients were included, 64.8% were SARS-CoV-2 positive and 14.9% were managed in critical care, and 22.1% of SARS-CoV-2 infections were considered probable or definite nosocomial infections. On the survey day, antibiotic prevalence was 45.0% and 73.9% were prescribed for suspected respiratory tract infection. Amoxicillin, doxycycline and co-amoxiclav accounted for over half of all antibiotics in non-critical care wards and meropenem, piperacillin-tazobactam and co-amoxiclav accounted for approximately half prescribed in critical care. Of all SARS-CoV-2 patients, 38.3% were prescribed antibiotics. In a multivariable logistic regression analysis, COPD/chronic lung disease and CRP ≥ 100 mg/l were associated with higher odds and probable or confirmed nosocomial COVID-19, diabetes and management on an elderly care ward had lower odds of an antibiotic prescription. Systemic antifungals were prescribed in 9.8% of critical care patients and commenced a median of 18 days after critical care admission. INTERPRETATION A relatively low prevalence of antibiotic prescribing in SARS-CoV-2 hospitalised patients and low proportion of broad spectrum antibiotics in non-critical care settings was observed potentially reflecting national antimicrobial stewardship initiatives. Broad spectrum antibiotic and antifungal prescribing in critical care units was observed indicating the importance of infection prevention and control and stewardship initiatives in this setting. FUNDING The Scottish Antibiotic Prescribing Group is funded by Scottish Government.

Abstract
Given the large number of patients seen in the emergency department (ED) and concerns with antibiotic overprescribing, the ED is an important setting to target for antimicrobial stewardship (AS) initiatives. The ED is positioned between ambulatory and inpatient settings, making AS collaboration with clinicians and other health care providers in the hospital, long-term care facilities, and ambulatory settings critical to success. This article details ED-focused AS strategies on empiric antimicrobial selection, prompt administration, preventing ED return and readmissions, suggested collaborations between ED AS leadership and other key partners, and potential future strategies for expansion.

Abstract
Antimicrobial stewardship efforts that include surgeons rely on healthy and open communications between surgeons, infectious diseases specialists, and pharmacists. These efforts most frequently are related to surgical prophylaxis, the management of surgical infections, and surgical critical care. Policy should be based on best evidence and timely interactions to develop consensus on how to develop appropriate guidelines and protocols. Flexibility on all sides leads to increasingly strong relationships over time.

Abstract
BACKGROUND A majority of patients with community-acquired pneumonia (CAP) receive antibiotics. According to the evidence, 5-7 days of treatment should be sufficient for most patients. Many, however, are treated longer than recommended. We have previously conducted a quality improvement study to ensure guideline-conform treatment for CAP. However, the impact of the interventions on antibiotic use has not been investigated. OBJECTIVE To estimate the impact of an eight-month stewardship program on antibiotic use. METHODS We conducted a before-after study comparing a four-month baseline period with data from a corresponding follow-up period. We performed univariable and multivariable logistic regression to compare odds for ≤7 days of total antibiotic treatment, ≤3 days of intravenous treatment and the proportion of correct empiric antibiotics. As sensitivity analysis, we repeated the univariable logistic regression on a propensity score-matched cohort by using the same variables we used for adjustments in the multivariable analysis. We also performed subgroup analyses for patients stable ≤72 h of admission. RESULTS In total, 771 patients were included. Compared to preintervention, the unadjusted odds ratio (OR) for ≤7 days of total antibiotic treatment were 1.84 (95% CI 1.34-2.54) for the whole population and 2.08 (1.41-3.10) for the stable patients. The OR for ≤3 days of intravenous antibiotics were 1.16 (0.87-1.54) and 1.38 (0.87-2.22), respectively. The OR for correct empiric antibiotics were 1.96 (1.45-2.68) and 1.82 (1.23-2.69). Comparable results regarding all outcomes were derived from the other analyses. CONCLUSION The program resulted in a significantly lower overall antibiotic exposure and a higher proportion of patients treated with the recommended antibiotics without a the reduction of exposure to intravenous antibiotics significantly.

Abstract
BACKGROUND Early-onset sepsis (EOS) is a potentially life-threatening complication of birth. Clinical symptoms are often unspecific and biomarkers have low predictive values for EOS. Therefore, clinical suspicion often leads to antibiotic therapy in neonates with a negative blood culture. In the study we evaluated if a quality improvement initiative could reduce unwarranted antibiotic use in a safe way in term neonates with culture-negative sepsis. METHODS The quality improvement initiative included new treatment guidelines and were introduced on 11 June 2018. The guidelines included C-reactive protein- and clinical symptoms-guided decision-making and shorter intravenous antibiotic therapy. All term neonates treated for EOS at Ryhov Hospital, Jönköping, Sweden were studied before (period 1: 2016-2017) and after the introduction of the new guidelines (period 2: 11 June 2018 to 30 Sept 2019). Laboratory and clinical data were analysed. RESULTS There were 7618 term neonates in period 1 and 5005 term neonates in period 2. We identified 140 (1.8%) EOS in period 1 and 97 (1.9%) EOS in period 2. During period 1 and 2, there were 61 (61/140, 44%) and 59 (59/97, 61%) EOS neonates, respectively, who met the criteria for shorter antibiotic treatment. The number of positive blood cultures were seven (0.92/1000 live births) and five (1.0/1000 live births) in period 1 and 2. The median C-reactive protein were 52 mg/L (37-62) in period 1 and 42 mg/L (31-56) in period 2 in the group who met the criteria of the guidelines. The duration of antibiotic therapy (Median: seven vs. five days, p < 0.001) and hospital stay (Median: seven vs. five days, p < 0.001) as well as healthcare costs (decreased by €122,000/year) was reduced in the group who met the criteria after the introduction of the guidelines. CONCLUSION C-reactive protein- and clinical symptoms-guided decision-making for EOS significantly decreased the duration of antibiotic therapy and hospital stay, and hence reduced healthcare costs, with no reinfection in a cohort of term infants. TRIAL REGISTRATION Trial registration number: ISRCTN29535824 . Date of registration: 28 May 2020. Retrospectively registered.

Abstract
INTRODUCTION We assessed the knowledge of, attitude toward antimicrobial resistance (AMR) and practice of antimicrobial stewardship (AMS) among physicians in Nigeria to provide future guidance to the Nigerian National Action Plan for AMR. METHODS A descriptive cross-sectional questionnaire-based study explored the physicians' self-reported practice of antibiotic prescribing, knowledge, attitude, and practice of AMR and components of ASPs. RESULTS The majority (217; 67.2%) of respondents prescribed antibiotics daily in their clinical practice AMR was recognized as a global and local problem by 308 (95.4%) and 262 (81.1%) respondents, respectively. Only 91 (28.2%) of respondents have ever heard of antibiotic stewardship. The median AMR knowledge score was 40 (19-45)out of 45while that for ASP was 46.0(32-57) out of 60. There was significant statistical difference between the ASP median scores among the medical specialties category (P value <0.0001) More respondents had good knowledge of AMR than ASPs (82.7% versus 36.5%; p < 0.0001). CONCLUSION Respondents in this study were more knowledgeable about AMR than AMS and its core components.

Abstract
Improving the practices of antimicrobial use in hospitals, especially in developing countries, is a challenging duty. OBJECTIVES The aim of the study was to determine the effect of certain stewardship actions on the use of antibiotics for device-associated infections in the emergency intensive care unit in Egypt. MEHODS The intervention included establishment of AS team, design an antibiogram and preparation of antibiotic use guidelines, education, and infection prevention and control measures. Pre- and postinterventions surveys tookplace including: antibiotic prescription compliance, antibiotic cost, bacterial profile and antibiotic resistance rates. RESULTS Antibiotic prescription compliance improved, especially for prophylactic antibiotics prescription; in preintervention phase, 27.4% of cases received unindicated antibiotic prophylaxis vs 5.8% after intervention. A statistically significant decrease in cost after the intervention was reported (p = 0.04). Acinetobacter baumannii and Klebsiella pneumonia were the most frequently isolated pathogens (25.6%) and (21.8%) in pre and post-intervention phases respectively. A statistically significant decrease in the prevalence of MDR (X² = 11.9, p = 0.009) was observed. The most prevalent XDR is K-pneumonia (45% vs 17%) in phase 1&3. No pan drug-resistant isolates were detected. CONCLUSION Sound antibiotic guidelines coupled with effective infection control precautions and education would be a good intervention, particularly with a leadership commitment. The use of microbiology tests to direct prescribing decisions should be a underscored. Sustained research initiatives may support the proper implementation of AS programmes in limited resource settings.

Abstract
BACKGROUND Hospital antibiotic use is rising. We aimed to evaluate the antibiotic-use prevalence and length of stay. METHODS We conducted a single-center retrospective study of patients < 18-years-old admitted to general pediatric services who received ≥ 1 antibiotic over six months. Demographics, culture results and antibiotic details were collected. The primary outcome was to identify the total number and classes of antibiotics prescribed during the admission. Secondary outcomes included length of stay (LOS), culture results, and the most commonly used antibiotics. RESULTS Forty-eight percent of patients received monotherapy (single class antibiotic). Cephalosporins (55%), vancomycin (35%), and clindamycin (22%) were prescribed more commonly than other antibiotic classes. Children were exposed up to 4 classes of antibiotics (range 1-4). A moderate correlation existed between the length of stay and the number of antibiotic classes used (R2 = 0.38). Two or more classes of antibiotic use prolonged the length of stay. Cephalosporin use was associated with 35% reduced LOS (95 CI, 21%-57%), and penicillin use correlated with 38% more prolonged LOS (95 CI, 22%-66%). CONCLUSIONS Antibiotic use in pediatric hospitals was high, and children received multiple classes of antibiotics. Inappropriate antibiotic use and culture results may have an untoward effect on hospital length of stay.

Abstract
Background and Aims: The study was undertaken to assess the empirical antibiotic prescription in uncomplicated urinary tract infection (UTI) cases and compare them with the Indian council of medical research (ICMR) 2017 guidelines on antimicrobial use. The objective of this study was to study the compliance of prescriptions for uncomplicated UTI with respect to the guidelines recommended by ICMR and assess the success rates in terms of mean days taken to achieve symptomatic relief. Methodology: This study was conducted on patients (of age >16 years) presenting to the Urology, Medicine and Gynecology OPD with complaints of uncomplicated UTI over two months. Descriptive statistics were used to assess the results. Results: A total of 115 UTI patients were enrolled and followed up for symptomatic relief. 67 (58.26%) patients were prescribed antibiotics, the preferred ones were levofloxacin 500 mg O.D. in 24 (35.82%), nitrofurantoin 100 mg B.D. in 21 (31.34%) and levofloxacin 750 mg O.D. in 6 (8.95%) patients for a mean duration of 7.83 ± 2.37, 7.52 ± 2.68 and 4.33 ± 1.03 days respectively. Symptomatic relief was seen in 6 (25%), 15 (71.42%) and 4 (66.67%) cases within 5 ± 0.63 days, 4.2 ± 2.11 days and 4.5 ± 1 days, respectively. Discussion: 23 (34.32%) prescriptions based on choice of empirical antibiotic and 17 (25.37%) prescriptions based on both choice of antibiotic and duration of therapy were found to be compliant with the (ICMR) -2017 guidelines. Results show decreased efficacy of co-trimoxazole and ciprofloxacin as empirical therapy for acute uncomplicated UTI.

Antibiotic appropriateness and adherence to local guidelines in perioperative prophylaxis: results from an antimicrobial stewardship intervention. Antimicrob Resist Infect Control 2020; 9:164. [PMID: 33106190 PMCID: PMC7586646 DOI: 10.1186/s13756-020-00814-6] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2020] [Accepted: 09/04/2020] [Indexed: 02/07/2023] Open
Abstract
Objectives Surgical antibiotic prophylaxis (SAP) represents a major indication of antibiotic consumption worldwide. The present study aims to report the results of an enabling, long-term AMS intervention conducted between 2013 and 2019 on an Italian University Hospital performing more than 40.000 surgical interventions per year. Methods SAP inappropriateness was defined according to the ASHP guidelines and divided in four main categories: indication, selection and dosing, duration, timing. Between 2013 and 2019, we conducted a continuative AMS intervention over 14 surgical departments that included enablement, review of selected clinical records and feedback. Results We collected a total of 789 SAP prescribed to 735 patients (mean age 56.7 ± 17.8y). Overall, guideline adherence improved from 36.6% (n = 149) at baseline to 57.9% (n = 221) post-intervention (P < 0.0001). A significant improvement (P < 0.001) was also detected for each category: indication (from 58.5 to 93.2%), selection and dosing (from 58.5 to 80.6%), timing (from 92.4 to 97.6%), duration (from 71 to 80.1%). Conclusions Though results cannot be generalized to all hospital populations, enabling AMS interventions may be effective in establishing a sustained improvement in SAP appropriateness rates. Once identified the main causes of SAP inappropriateness, tailored AMS interventions for each department may be beneficial. Further studies are needed to evaluate specific outcomes as incidence of surgical site infections and antimicrobial resistance.

Time and personnel requirements for antimicrobial stewardship in small hospitals in a rural area in Germany. J Infect Public Health 2020; 13:1946-1950. [PMID: 33121907 DOI: 10.1016/j.jiph.2020.10.001] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2020] [Revised: 09/02/2020] [Accepted: 10/05/2020] [Indexed: 10/23/2022] Open
Abstract
BACKGROUND In order to control their anti-infectives consumption, hospitals are required to provide multidisciplinary teams comprising among others an infectiologist, a microbiologist and a pharmacist. Small hospitals though often do not dispose of the defaulted personnel. This study illustrates a solution for an antimicrobial stewardship program (ASP) in small community hospitals in a rural area in Germany. METHODS Four hospitals of ca. 200 beds each, jointly hired an antimicrobial stewardship expert to start a common ASP. This expert did rounds on every ward once a week, mostly as chard reviews with the physician in charge. Outside the rounds, he could be consulted by mail. Working time and number of visited patients were documented. Anti-infectives consumption, incidence of Clostridioides difficile infections (CDI) and mortality rates were retrieved from routinely collected data. The intervention period (01/2018-12/2018) was compared to the preintervention period (01/2017-12/2017). RESULTS 3321 patients were visited in the intervention period. In average, 20 patients were seen per day and 20 min were needed per patient/ chard. About 65% of the expert's working time was needed for rounds, 15% for driving between the hospitals. The anti-infectives consumption of the 4 hospitals in the preintervention period amounted to 50 defined daily doses per 100 occupied bed days. The total consumption was reduced by 10% and of quinolones by 36%. The incidence of hospital-acquired CDI receded from 0.14 to 0.07 cases per 100 patient days (-50%, p = 0.001). The overall in-hospital mortality did not change. CONCLUSIONS A single expert was able to implement a successfull ASP in 4 hospitals. While multidisciplinary antimicrobial stewardship teams are ideal for tertiary care hospitals, small hospitals need a more practical solution. This survey shows that one expert can be sufficient for several small hospitals even with the distances in a rural setting.

Abstract
OBJECTIVE Assess the effectiveness of a multifaceted stewardship intervention to reduce frequency and duration of inappropriate antibiotic use for emergency department (ED) patients with skin and soft tissue infections (SSTI). We hypothesized the antibiotic stewardship program would reduce antibiotic duration and improve guideline adherence in discharged SSTI patients. DESIGN Nonrandomized controlled trial. SETTING Academic EDs (intervention site and control site). PATIENTS OR PARTICIPANTS Attending physicians and nurse practitioners at participating EDs. INTERVENTION(S) Education regarding guideline-based treatment of SSTI, tests of antimicrobial treatment of SSTI, implementation of a clinical treatment algorithm and order set in the electronic health record, and ED clinicians' audit and feedback. RESULTS We examined 583 SSTIs. At the intervention site, clinician adherence to guidelines improved from 41% to 51% (aOR = 2.13 [95% CI: 1.20-3.79]). At the control site, there were no changes in adherence during the "intervention" period (aOR = 1.17 [0.65-2.12]). The between-site comparison of these during vs. pre-intervention odds ratios was not different (aOR = 1.82 [0.79-4.21]). Antibiotic duration decreased by 26% at the intervention site during the intervention compared to pre-intervention (Adjusted Geometric Mean Ratio [95% CI] = 0.74 [0.66-0.84]). Adherence was inversely associated with SSTI severity (severe vs mild; adjusted OR 0.42 [0.20-0.89]) and purulence (0.32 [0.21-0.47]). Mean antibiotic prescription duration was 1.95 days shorter (95% CI: 1.54-2.33) in the time period following the intervention than pre-intervention period. CONCLUSIONS A multifaceted intervention resulted in modest improvement in adherence to guidelines compared to a control site, driven by treatment duration reductions.

A pharmacist-led prospective antibiotic stewardship intervention improves compliance to community-acquired pneumonia guidelines in 39 public and private hospitals across South Africa. Int J Antimicrob Agents 2020; 56:106189.

Abstract
INTRODUCTION Pharmacists in low-middle-income countries (LMIC) are few and lack antibiotic stewardship (AS) training. The ability was assessed of non-specialised pharmacists to implement stewardship interventions and improve adherence to the South African community-acquired pneumonia (CAP) guideline in public and private hospitals. METHODS This was a multicentre, prospective cohort study of adult CAP patients hospitalised between July 2017 and July 2018. A CAP bundle was developed of seven process measures (diagnostic and AS) that pharmacists used to audit compliance and provide feedback. CAP bundle compliance rates and change in outcome measures [mortality, length of stay (LOS) and infection-related (IR)-LOS] during pre- and post-implementation periods were compared. RESULTS In total, 2464 patients in 39 hospitals were included in the final analysis. Post-implementation, overall CAP bundle compliance improved from 47·8% to 53·6% (confidence interval [CI] 4·1-7·5, p<0·0001), diagnostic stewardship compliance improved from 49·1% to 54·6% (CI 3·3-7·7, p<0·0001) and compliance with AS process measures from 45·3% to 51·6% (CI 4·0-8·6, p<0·0001). Improved compliance with process measures was significant for five (2 diagnostic, 3 AS) of seven components: radiology, laboratory, antibiotic choice, duration and intravenous to oral switch. There was no difference in mortality between the two phases, [4·4%(55/1247) vs. 3·9%(47/1217); p=0·54], median LOS or IR LOS 6·0 vs. 6·0 days (p=0·20) and 5·0 vs. 5·0 days (p=0·40). CONCLUSION Non-specialised pharmacists in public and private hospitals implemented stewardship interventions and improved compliance to SA CAP guidelines. The methodology of upskilling and a shared learning stewardship model may benefit LMIC countries.

Abstract
Background The etiology of community-acquired pneumonia (CAP) has evolved since the beginning of the antibiotic era. Recent guidelines encourage immediate empiric antibiotic treatment once a diagnosis of CAP is made. Concerns about treatment recommendations, on the one hand, and antibiotic stewardship, on the other, motivated this review of the medical literature on the etiology of CAP. Methods We conducted a systematic review of English-language literature on the etiology of CAP using methods defined by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We searched PubMed using a combination of the keywords ‘pneumonia’, ‘CAP’, ‘etiology’, ‘microbiology’, ‘bacteriology’, and ‘pathogen’. We examined articles on antibiotics that were develop to treat pneumonia. We reviewed all ‘related articles’ as well as studies referenced by those that came up in the search. After we excluded articles that did not give sufficient microbiological data or failed to meet other predetermined criteria, 146 studies remained. Data were stratified into diagnostic categories according to the microbiologic studies that were done; results are presented as the percentage in each category of all cases in which an etiology was established. Results Streptococcus pneumoniae remains the most common cause of CAP although declining in incidence; this decline has been greater in the US than elsewhere. Haemophilus influenzae is the second most common cause of CAP, followed by Staphylococcus aureus and Gram negative bacilli. The incidence of all bacteria as causes of CAP has declined because, with routine use of PCR for viruses, the denominator, cases with an established etiology, has increased. Viruses were reported on average in about 10% of cases, but recent PCR-based studies identified a respiratory virus in about 30% of cases of CAP, with substantial rates of viral/bacterial coinfection. Conclusion The results of this study justify current guidelines for initial empiric treatment of CAP. With pneumococcus and Haemophilus continuing to predominate, efforts at antibiotic stewardship might be enhanced by greater attention to the routine use of sputum Gram stain and culture. Because viral/bacterial coinfection is relatively common, the identification of a virus by PCR does not, by itself, allow for discontinuation of the antibiotic therapy.

Antibiotic prescribing and non-prescribing in nursing home residents with signs and symptoms ascribed to urinary tract infection (ANNA): study protocol for a cluster randomized controlled trial. BMC Geriatr 2020; 20:341. [PMID: 32912192 PMCID: PMC7488520 DOI: 10.1186/s12877-020-01662-0] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2019] [Accepted: 07/22/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Antibiotic overprescribing for suspected urinary tract infection (UTI) in nursing homes (NHs) is common. Typical clinical scenarios in which antibiotics are inappropriately prescribed include response to nonspecific signs and symptoms and/or a positive urine test in the absence of symptoms referable to the urinary tract. These and other scenarios for inappropriate antibiotic prescribing were addressed in a recent international Delphi study which resulted in the development of a decision tool for the empiric treatment of UTI in frail older adults. The aim of the current study is to implement this decision tool, by integrating it into the electronic health record (EHR) and providing education on its content and use, and to evaluate its effect on appropriate antibiotic prescribing. An additional aim is to evaluate the quality of the intervention and the implementation process. METHODS A cluster Randomized Controlled Trial (cRCT) is conducted in sixteen NHs and aims to include 897 residents diagnosed with suspected UTI. NHs in the intervention group use the EHR-integrated decision tool, and receive education for physicians and nursing staff; in the control group care as usual is provided. Data is collected through case report forms within the EHR at the day of diagnosis and at 3, 7, and 21 days thereafter. The primary outcome is appropriate antibiotic prescribing for suspected UTI at the day of diagnosis. Secondary outcomes include the course of symptoms, alternative diagnoses, treatment changes, complications, hospitalization, and mortality. Data on total antibiotic prescribing are additionally collected in the participating NHs 12 months before and during the study. Finally, the process evaluation combines cRCT data with questionnaires and qualitative interviews with NH professionals. DISCUSSION This is the first cRCT to evaluate the recently developed, international decision tool for empiric treatment of suspected UTI in NH residents. Study findings will elucidate the effect of the intervention on appropriate antibiotic prescribing for suspected UTI, and provide insight into the applicability of the decision tool in NHs in general and in specific subgroups of NH residents. With this study we aim to contribute to antibiotic stewardship efforts in long-term care. TRIAL REGISTRATION The ANNA study was registered at the Netherlands Trial Register on 26 February 2019, with identification number NTR NL7555 .

Abstract
Background Antimicrobial resistance (AMR) is one of the most urgent global health threats with low-resource countries being disproportionately affected. Targeted interventions require insight in antibiotic prescription practices. A point prevalence survey (PPS) is a well-known tool to get insight in antibiotic dispensing practices in hospitals and identify areas for improvement. Here, we describe the results of a PPS performed in a tertiary, regional and district hospital in Kilimanjaro region in Tanzania. Methods A PPS was performed in the Kilimanjaro Christian Medical Centre (KCMC; tertiary hospital), Mawenzi (regional) and St. Joseph (district) hospital in November and December 2016. Antibiotic use in all patients admitted more than 24 h and those undergoing surgery was recorded. All clinical wards were included except the pediatrics. Data from a single ward were collected on the same day. Results A total of 399 patients were included in the PPS: 232 patients from KCMC, 94 from Mawenzi hospital and 73 patients from St. Joseph hospital. Overall prevalence of antibiotic use was 44.0%: 38% in KCMC, 59% in Mawenzi and 63% in St. Joseph. Ceftriaxone (n = 94, 29.8%), metronidazole (n = 79, 23.9%) and other antibiotics belonging to the penicillin class (n = 89, 28.3%) were most commonly prescribed. Antibiotics prescribed for surgical prophylaxis were continued for more than 3 days in 57% of cases. Conclusion Our study shows a rate of broad-spectrum antibiotic use in Tanzanian hospitals and prolonged surgical antibiotic prophylaxis being a common practice. PPS is an important tool to improve future antibiotic use in Tanzania hospitals.

Abstract
BACKGROUND Inappropriate antibiotics use and antimicrobial resistance (AMR) are increasingly becoming global health issues of great concern. Despite the established antibiotic stewardship programmes (ASPs) in many countries, limited efforts have been made to engage nurses and clearly define their roles in ASPs. AIM An exploratory qualitative study was conducted to understand the facilitators and barriers that impact nurses' involvement and empowerment in antibiotic stewardship. METHODS Focus group discussions (FGDs) were conducted with purposively sampled nurses from three major public hospitals in Singapore. FGDs were audio-recorded and transcribed verbatim. Data were analysed using Applied Thematic Analysis and interpreted using the Social Ecological Model. FINDINGS At the intrapersonal level, nurses felt empowered in carrying out their roles in antibiotic administration. They saw themselves as gatekeepers to ensure that the prescribed antibiotics were administered appropriately. However, nurses felt they lacked the knowledge and expertise in antibiotic use and AMR prevention. At the interpersonal level, this deficit in knowledge and expertise in antibiotic use impacted how they were perceived by patients and caregivers as well as their interactions with the primary care team when voicing outpatient safety concerns and antibiotic administration suggestions. At the organizational level, nurses relied on drug administration guidelines to ensure appropriate antibiotic administration and as a safety net when physicians questioned their clinical practice. At the community level, nurses felt there was a lack of awareness and knowledge on antibiotic use among the general population. CONCLUSION These findings provide important insights to harness the contributions of nurses, and to formally acknowledge and enlarge their roles in ASPs.
