Introduction Telemedicine technologies are increasingly being incorporated into infectious disease practice. We aimed to demonstrate the impact of antimicrobial stewardship through telemedicine on bacterial resistance rates. Methods We conducted a quasi-experimental study in a 220-bed hospital in southern Brazil. An antimicrobial stewardship program incorporating the use of telemedicine was implemented. Resistance and antimicrobial consumption rates were determined and analysed using a segmented regression model. Results After the intervention, the rate of appropriate antimicrobial prescription increased from 51.4% at baseline to 81.4%. Significant reductions in the consumption of fluoroquinolones (level change, β = −0.80; P < 0.01; trend change, β = −0.01; P = 0.98), first-generation cephalosporins (level change, β = −0.91; P < 0.01; trend change, β = +0.01; P = 0.96), vancomycin (level change, β = −0.47; P = 0.04; trend change, β = +0.17; P = 0.66) and polymyxins (level change, β = −0.15; P = 0.56; trend change, β = −1.75; P < 0.01) were identified. There was an increase in the consumption of amoxicillin + clavulanate (level change, β = +0.84; P < 0.01; trend change, β = +0.14; P = 0.41) and cefuroxime (level change, β = +0.21; P = 0.17; trend change, β = +0.66; P = 0.02). A significant decrease in the rate of carbapenem-resistant Acinetobacter spp. isolation (level change, β = +0.66; P = 0.01; trend change, β = −1.26; P < 0.01) was observed. Conclusions Telemedicine, which provides a tool for decision support and immediate access to experienced specialists, can promote better antibiotic selection and reductions in bacterial resistance.

BackgroundThis study aimed to examine the impact of an intervention carried out in 2011 to combat multi-drug resistance and outbreaks of imipenem-resistant Acinetobacter baumannii (IRAB), and to explore its resistance mechanism.MethodsA total of 2572 isolates of A. baumannii, including 1673 IRAB isolates, were collected between 2007 and 2014. An intervention was implemented to control A. baumannii resistance and outbreaks. Antimicrobial susceptibility was tested by calculating minimal inhibitory concentrations (MICs), and outbreaks were typed using pulsed-field gel electrophoresis (PFGE). Resistance mechanisms were explored by polymerase chain reaction (PCR) and whole genome sequencing (WGS).ResultsFollowing the intervention in 2011, the resistance rates of A. baumannii to almost all tested antibiotics decreased, from 85.3 to 72.6% for imipenem, 100 to 80.8% for ceftriaxone, and 45.0 to 6.9% for tigecycline. The intervention resulted in a decrease in the number (seven to five), duration (8–3 months), and departments (five to three) affected by outbreaks; no outbreaks occurred in 2011. After the intervention, only blaAMPC (76.47 to 100%) and blaTEM–1 (75.74 to 96.92%) increased (P &lt; 0.0001); whereas blaGES–1 (32.35 to 3.07%), blaPER–1 (21.32 to 1.54%), blaOXA–58 (60.29 to 1.54%), carO (37.50 to 7.69%), and adeB (9.56 to 3.08%) decreased (P &lt; 0.0001). Interestingly, the frequency of class B β-lactamase genes decreased from 91.18% (blaSPM–1) and 61.03% (blaIMP–1) to 0%, while that of class D blaOXA–23 increased to 96.92% (P &lt; 0.0001). WGS showed that the major PFGE types causing outbreaks each year (type 01, 11, 18, 23, 26, and 31) carried the same resistance genes (blaKPC–1, blaADC–25, blaOXA–66, and adeABC), AdeR-S mutations (G186V and A136V), and a partially blocked porin channel CarO. Meanwhile, plasmids harboring blaOXA–23 were found after the intervention.ConclusionThe intervention was highly effective in reducing multi-drug resistance of A. baumannii and IRAB outbreaks in the long term. The resistance mechanisms of IRAB may involve genes encoding β-lactamases, efflux pump overexpression, outer membrane porin blockade, and plasmids; in particular, clonal spread of blaOXA–23 was the major cause of outbreaks. Similar interventions may also help reduce bacterial resistance rates and outbreaks in other hospitals.

Abstract Background Despite multiple reports of the benefits of antimicrobial stewardship programs (ASPs) in developed countries, regarding patient safety, decrease in antimicrobial resistance, consumption and spending on antimicrobials, there is very limited evidence of the same benefits in a different economic and social context. The objective of this study was to evaluate the clinical and economic impact of the implementation of an ASP in Colombia. Methods We conducted a multicenter, quasi-experimental cohort study in four Colombian healthcare institutions between 2007 and 2014 including 900 patients (429 patients before and 471 after the implementation of the ASP) to evaluate the impact of these programs. Results Compared to the pre-ASP, the post-ASP group showed a greater adherence to the use of the empirical therapy and de-escalation based on the guidelines (45% vs. 9% and 92% vs. 8%, respectively; p < 0.001), as well as a higher proportion of clinical cure at the end of treatment and lower mortality (93% vs. 74% and 14% vs. 28%, respectively; p < 0.001). In the post-ASP patient group the opportunity for clinical improvement was 10 times greater compared with the pre-ASP group (adjusted OR = 10.40 95% CI 1.21-89.41) and there were less complications following targeted management (adjusted OR = 0.49 95% CI 0.25-0.97). Furthermore, after the implementation of the ASP there was lower average expenditure associated with hospital stay, laboratory tests, infectious diseases consultation, and empirical antimicrobial therapy choice. Conclusion With this study, we were able to show that even in limited income countries, ASPs are feasible to implement.

Abstract Background In a private hospital without restrictions on antibiotic prescription, the success of an Antimicrobial Stewardship Program (ASP) depends mainly on prospective feedback and education. Previously, the ASP of this hospital (PROA-HCB) managed to achieve a positive impact on the antibiotic prophylaxis in cesarean delivery. The purpose of this study is to characterize the impact after implementing the PROA-HCB on the optimal prophylaxis selection of all the procedures included in the clinical guideline for surgical antibiotic prophylaxis in adult patients. Methods A retrospective observational study that compares the selection, duration, antibiotic consumption, bacterial resistance profiles and patient’s safety outcomes regarding antibiotic use for all surgical prophylaxis prescription over six months for the periods before (pre-ASP) and after a five-year intervention of PROA-HCB (post-ASP). Results After a five-year intervention, the percentage of optimal selection of antibiotic prophylaxis in Surgery was 21.0% (N=1598) in the pre-ASP period and 80.0% (N=841) in the post-ASP period (59% absolute improvement, p &lt; 0.001). Percentage of optimal duration was 69,1% (N=1598) in the pre-ASP period and 78.0% (N=841) in the post-ASP period (8.9% absolute improvement, p &lt; 0.001). Mean ceftriaxone utilization was 217.7 defined daily doses (DDD) per 1,000 patient days DDD for the pre-ASP period and 139.8 DDD per 1,000 patient days for the ASP period (35.8% decrease; p = 0.019). Mean cefazolin utilization was 14.9 DDD per 1,000 patient days for the pre-ASP period and 153.3 DDD per 1,000 patient days for the ASP period (928.6% increase; p = 0.021). Regarding percentage of bacterial resistance, there was detected an improvement in some isolates like Escherichia coli with a decrease of ESBL detection (11% decrease; p = 0.007). In addition, no serious adverse reactions or an increase in surgical site infections were detected after the intervention. Conclusion The implementation of an ASP in the surgical ward showed an overall positive impact on selection and duration of antibiotic prophylaxis. Furthermore, this intervention could have had a positive impact on antimicrobial resistance and at the same time had no negative effects on the patients.

Objective. To measure the impact generated by the implementation of the pharmacy-driven antimicrobial stewardship program of the Clínica Bíblica Hospital. Methods. This is a retrospective observational study that evaluates the consumption of antibiotics for the periods before and during implementation of the Clínica Bíblica Hospital antimicrobial stewardship program, calculated by means of defined daily dose per 1 000 patient-days and days of therapy per 1 000 patient-days. In addition, bacterial resistance patterns for the periods 2014–2015 and 2016–2017 were compared. Results. Consumption of most-used antibiotics was calculated, looking for trends that might be associated with the activities implemented by the Clínica Bíblica Hospital antimicrobial stewardship program. Comparing some of the antibiotics with the highest consumption in periods I and II, use of levofloxacin and ceftriaxone showed a decrease of 54.0% (p < 0.001) and 14.6% (p = 0.003), respectively, whereas there was an increase in the use of cefazolin of 4 539.3% (p < 0.001). Regarding percentage of bacterial resistance, in most bacterial isolates no statistically significant changes were observed between the two periods. Conclusions. A reduction in the overall consumption of antibiotics has been achieved over time, most likely attributable to the antimicrobial stewardship program. However, this trend was not observed for all the antibiotics studied. The pattern of resistance among the commonly isolated microorganisms did not vary greatly between the periods studied, which suggests that either the antimicrobial stewardship program may have prevented an increase in bacterial resistance since its implementation, or that it is too soon to see impact on bacterial resistance.

Abstract Objective The The impact of a hospital antimicrobial stewardship was determined on antimicrobial-resistant, Clostridioides difficile rates and the amount of antimicrobial consumed in cancer patients.The intervention effects of antimicrobial stewardship (ASP) plans in 2017–2018 and 2018–2019 were respectively evaluated among hematology/oncology and bone marrow transplant patients in Ayatollah Taleghani University Hospital, Tehran, Iran. In this interventional quasi-experimental study, the ASP repository was utilized to capture four survey questions encompassed in these immunocompromised patients: amount of antibiotics (meropenem and vancomycin) consumption gr-year, the number of positive Clostridioides difficile infection and multidrug-resistant positive cases in blood cultures. Results The number of MDR cases in the periods of 2017–2018 and 2018–2019 were 145 and 75, respectively (p = 0.011). A significant reduction in all positive blood cultures from 2017–2018 to 2018–2019 was found (p = 0.001). 574 patients admitted to our hospital in these periods of 2017- 2018 and 2018- 2019were assessed for MPM and VMN use. The amounts of MPM prescriptions in 2018–2019 was significantly decreased from 22464 to 17262 g (p = 0.043). The significant reduction in antibiotic consumption, MDR organisms, and CDI can highly promote patients’ health and decreasing medical costs and long-term defects for patients.

Abstract Background Implementation of the Accelerate PhenoTM Gram-negative platform (RDT) paired with antimicrobial stewardship program (ASP) intervention projects to improve time to institutional-preferred antimicrobial therapy (IPT) for Gram-negative bacilli (GNB) bloodstream infections (BSIs). However, few data describe the impact of discrepant RDT results from standard of care (SOC) methods on antimicrobial prescribing. Methods A single-center, pre-/post-intervention study of consecutive, nonduplicate blood cultures for adult inpatients with GNB BSI following combined RDT + ASP intervention was performed. The primary outcome was time to IPT. An a priori definition of IPT was utilized to limit bias and to allow for an assessment of the impact of discrepant RDT results with the SOC reference standard. Results Five hundred fourteen patients (PRE 264; POST 250) were included. Median time to antimicrobial susceptibility testing (AST) results decreased 29.4 hours (P &lt; .001) post-intervention, and median time to IPT was reduced by 21.2 hours (P &lt; .001). Utilization (days of therapy [DOTs]/1000 days present) of broad-spectrum agents decreased (PRE 655.2 vs POST 585.8; P = .043) and narrow-spectrum beta-lactams increased (69.1 vs 141.7; P &lt; .001). Discrepant results occurred in 69/250 (28%) post-intervention episodes, resulting in incorrect ASP recommendations in 10/69 (14%). No differences in clinical outcomes were observed. Conclusions While implementation of a phenotypic RDT + ASP can improve time to IPT, close coordination with Clinical Microbiology and continued ASP follow up are needed to optimize therapy. Although uncommon, the potential for erroneous ASP recommendations to de-escalate to inactive therapy following RDT results warrants further investigation.

Background: The rise of antimicrobial resistance has made it critical for clinicians to understand antimicrobial stewardship principles. We sought to determine whether the opportunity to participate in an American Board of Pediatrics Maintenance of Certification Part 4 (MOC4) quality improvement (QI) project would engage pediatricians and improve their knowledge about antimicrobial stewardship. Methods: In August 2019, a new clinical algorithm for acute appendicitis, spearheaded by the antimicrobial stewardship program (ASP), was implemented at UCSF Benioff Children’s Hospital Oakland to standardize care and optimize antimicrobial use. Medical staff were invited to participate in a QI project evaluating the impact of this algorithm. Data were collected for the 2 quarters preceding implementation (baseline), for the quarter of implementation (transition period), and for the quarter after implementation. Participants were offered MOC4 credit for reviewing these 3 cycles of data and associated materials highlighting information about antimicrobial stewardship. An initial survey was given to participants to assess their baseline knowledge via 4 questions about antimicrobial use in surgical patients (Table 1). At the conclusion of the QI project, another survey was conducted to reassess participant knowledge and to evaluate overall satisfaction with the project. Results: In total, 150 clinicians completed the initial survey. Of these, 44% were general pediatricians and 56% were pediatric subspecialists. Based on years out of training, their levels of experience varied: >20 years in 24%, 11–20 years in 32.7%, 0–10 years in 34.7%, and currently in training in 8.7%. Of the 150 initial participants, 133 (89%) completed the QI project and the second survey. Between surveys, there was significant improvement in knowledge about the appropriate timing and duration of surgical antibiotic prophylaxis (Table 1). Moreover, 88% of participants responded that the QI project was extremely effective in helping them learn about antimicrobial stewardship principles and about ASP interventions. Conclusions: Participation in this MOC4 QI project resulted in significant improvement in knowledge about antimicrobial use in surgical patients, and the activity was perceived as a highly effective way to learn about antimicrobial stewardship. QI projects that leverage MOC4 credit can be a powerful tool for engaging pediatricians and disseminating education about antimicrobial stewardship.Funding: NoDisclosures: None

AbstractBackgroundAntimicrobial stewardship has been associated with a reduction in the incidence of health care associated Clostridium difficile infection (HA-CDI). However, CDI remains under-recognized in many low and middle-income countries where clinical and surveillance resources required to identify HA-CDI are often lacking. The rate of toxigenic C. difficile stool positivity in the stool of hospitalized patients may offer an alternative metric for these settings, but its utlity remains largely untested.Aim/ObjectiveTo examine the impact of an antimicrobial stewardship on the rate of toxigenic C. difficile positivity among hospitalized patients presenting with diarrhoeaMethodsA 12-year retrospective review of laboratory data was conducted to compare the rates of toxigenic C. difficile in diarrhoea stool of patients in a hospital in Saudi Arabia, before and after implementation of an antimicrobial stewardship programResultThere was a significant decline in the rate of toxigenic C difficile positivity from 9.8 to 7.4% following the implementation of the antimicrobial stewardship program, and a reversal of a rising trend.DiscussionThe rate of toxigenic C. difficile positivity may be a useful patient outcome metric for evaluating the long term impact of antimicrobial stewardship on CDI, especially in settings with limited surveillance resources. The accuracy of this metric is however dependent on the avoidance of arbitrary repeated testing of a patient for cure, and testing only unformed or diarrhoea stool specimens. Further studies are required within and beyond Saudi Arabia to examine the utility of this metric.
