Background:Clostridioides difficile is a gram-positive bacteria that is the most common cause of hospital-associated infectious diarrhea among traditional and nontraditional high-risk populations. Excess healthcare costs associate with C. difficile infection (CDI) prevalence, morbidity, and mortality is shown to economically impact the US healthcare system with at least an additional $1 billion in annual cost. Exposure to antimicrobial agents resulted in increased risk for hospital-onset CDI (HO-CDI) at an inner-city hospital during 2010 and 2011. Methods: A retrospective case-control study of all persons with HO-CDI in the MICU was conducted at an inner-city hospital between January 1, 2010, and December 31, 2011. A patient was considered to have developed HO-CDI if diarrhea developed after 72 hours of admission into the MICU and a confirmed laboratory stool specimen for Clostridioides difficile infection (CDI) was obtained. A non–HO-CDI person was randomly selected using “risk set sampling.” After the application of inclusion and exclusion criteria, 88 cases were eligible for the study. Of these cases, 29 met the definition for HO-CDI, and 59 met the definition for non–HO-CDI. The relationship between antimicrobial use and the development of HO-CDI in patients in the MICU at an inner-city hospital was investigated using a logistic regression model in which the variable of total antibiotics was used as a possible predictor for predicting a positive HO-CDI. Results: Logistic regression was utilized to determine the relationships between selected study variables and presence or absence of HO-CDI. Total antibiotics was significantly related to HO-CDI. The results of this analysis showed that total antibiotics was a significant predictor for HO-CDI. The total value of the coefficient B for this predictor was 0.47, and the exponentiated value (exp[B]) of this coefficient was 1.60 (95% CI, 1.08–2.35). In this sample, patients who had 1 or more antibiotics were at a 60% greater risk of having a positive HO-CDI culture. There was a significant association between the use of metronidazole and HO-CDI (p < .001). Conclusions: Antimicrobial stewardship is an integral part of patient safety. The findings from this study were instrumental in the implementation of a fledging antimicrobial stewardship program and the use of evidence-based practices at this inner-city hospital.Funding: NoDisclosures: None

Abstract Background Long-term care facilities (LTCF) often struggle with implementation of antimicrobial stewardship programs (ASP) that meet all CDC core elements (CE). The CDC recommends partnership with infectious diseases (ID)/ASP experts to guide ASP implementation. The Nebraska Antimicrobial Stewardship Assessment and Promotion Program (ASAP) is an initiative funded by NE DHHS via a CDC grant to assist healthcare facilities with ASP implementation. Methods ASAP performed on-site baseline evaluation of ASP in 5 LTCF (42–293 beds) in the spring of 2017 using a 64-item questionnaire based on CDC CE. After interviewing ASP members, ASAP provided prioritized facility-specific recommendations for ASP implementation. LTCF were periodically contacted in the next 12 months to provide implementation support and evaluate progress. The number of CE met, recommendations implemented, antibiotic starts (AS) and days of therapy (DOT)/1000 resident-days (RD), and incidence of facility-onset Clostridioides difficile infections (FO-CDI) were compared 6 to 12 months before and after on-site visits. Paired t-test and Wilcoxon signed rank test were used for statistical analyses. Results Multidisciplinary ASP existed in all 5 facilities at baseline with medical directors (n = 2) or directors of nursing (n = 3) designated as team leads. Median CE implemented increased from 3 at baseline to 6 at the end of follow-up (P = 0.06). No LTCF had all 7 CE at baseline. By the end of one year, 2 facilities implemented all 7 CE with the remaining implementing 6 CE. LTCF not meeting all CE were only deficient in reporting ASP metrics to providers and staff. Among the 38 recommendations provided by ASAP, 82% were partially or fully implemented. Mean AS/1000 RD reduced by 19% from 10.1 at baseline to 8.2 post-intervention (P = 0.37) and DOT/1000 RD decreased by 21% from 91.7 to 72.5 (P = 0.20). The average incidence of FO-CDI decreased by 75% from 0.53 to 0.13 cases/10,000 RD (P = 0.25). Conclusion Assessment of LTCF ASP along with feedback for improvement by ID/ASP experts resulted in more programs meeting all 7 CE. Favorable reductions in antimicrobial use and CDI rates were also observed. Moving forward, the availability of these services should be expanded to all LTCFs struggling with ASP implementation.

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.

The Impact

Clostridioides difficile is the most common cause of healthcare-associated infection and gastroenteritis-associated death in the USA. Adherence to guideline recommendations for treatment of severe C. difficile infection (CDI) is associated with improved clinical success and reduced mortality. The purpose of this study was to determine whether implementation of a pharmacist-led antimicrobial stewardship program (ASP) CDI initiative improved adherence to CDI treatment guidelines and clinical outcomes. This was a single-center, retrospective, quasi-experimental study evaluating patients with CDI before and after implementation of an ASP initiative involving prospective audit and feedback in which guideline-driven treatment recommendations were communicated to treatment teams and documented in the electronic health record via pharmacy progress notes for all patients diagnosed with CDI. The primary endpoint was the proportion of patients treated with guideline adherent definitive regimens within 72 hours of CDI diagnosis. Secondary objectives were to evaluate the impact on clinical outcomes, including length of stay (LOS), infection-related LOS, 30-day readmission rates, and all-cause, in-hospital mortality. A total of 233 patients were evaluated. The proportion of patients on guideline adherent definitive CDI treatment regimen within 72 hours of diagnosis was significantly higher in the post-interventional group (pre: 42% vs post: 58%, p=0.02). No differences were observed in clinical outcomes or proportions of patients receiving laxatives, promotility agents, or proton pump inhibitors within 72 hours of diagnosis. Our findings demonstrate that a pharmacist-led stewardship initiative improved adherence to evidence-based practice guidelines for CDI treatment.

Abstract Background In light of recently published clinical and pharmacokinetic data regarding the use of daptomycin in obese patients, the Charleston Area Medical Center (CAMC) Antimicrobial Stewardship Program implemented an adjusted body weight dosing strategy for obese patients. Along with this new dosing strategy, an effort to reduce drug waste was also implemented by restricting the timing of routinely scheduled daptomycin doses for inpatients. This study aims to determine the clinical outcomes for patients receiving daptomycin both before and after this policy change. Secondary objectives include assessing creatinine phosphokinase (CK) levels in the study participants, defining the risk of CK elevation with the coadministration of HMG Co-A reductase inhibitors and daptomycin, and assessing any reduction in drug waste for the pharmacy department. Methods This study is a single-center, one-group pretest-posttest, quasi-experimental study evaluating the implementation of a two-part daptomycin dosing policy. The pretest group included all patients meeting inclusion and exclusion criteria that received daptomycin at CAMC from September 1 - November 30, 2017. The new daptomycin dosing policy was implemented on September 1, 2018. The posttest group included all patients meeting the stated criteria that received daptomycin from September 1 - November 30, 2018. Results A total of 118 patients were included in this study. There were 5 (7.7%) treatment failures in the pretest group and 3 (5.7%) in the posttest group (P = 0.7). Of the patients with CK levels monitored, 6 (33%) were found to have significant elevations in the pretest group and 4 (40%) were found in the posttest group (P = 0.6). There was no difference observed in the risk of CK elevation with daptomycin administration in the presence of an HMG-CoA reductase inhibitor. For the two time periods reviewed, the pharmacy department purchased fewer vials of daptomycin in the posttest group. Conclusion Patients at CAMC receiving daptomycin after implementation of a new dosing policy did not experience an increased risk of treatment failure. The Antimicrobial Stewardship Program will continue to monitor patients receiving daptomycin therapy at CAMC. Disclosures All authors: No reported disclosures.

Background: Antimicrobial stewardship is a standard practice in health facilities to reduce both the misuse of antimicrobials and the risk of resistance. Objective: To determine the profile of antimicrobial use in the pediatric population of a university hospital centre from 2015/16 to 2018/19. Methods: In this retrospective, descriptive, cross-sectional study, the pharmacy information system was used to determine the number of days of therapy (DOTs) and the defined daily dose (DDD) per 1000 patient-days (PDs) for each antimicrobial and for specified care units in each year of the study period. For each measure, the ratio of 2018/19 to 2015/16 values was also calculated (and expressed as a proportion); where the value of this proportion was ≤ 0.8 or ≥ 1.2 (indicating a substantial change over the study period), an explanatory rating was assigned by consensus. Results: Over the study period, 94 antimicrobial agents were available at the study hospital: 70 antibiotics (including antiparasitics and antituberculosis drugs), 14 antivirals, and 10 antifungals. The total number of DOTs per 1000 PDs declined from 904 in 2015/16 to 867 in 2018/19. The 5 most commonly used antimicrobials over the years, expressed as minimum/maximum DOTs per 1000 PDs, were piperacillin-tazobactam (78/105), trimethoprim-sulfamethoxazole (74/84), ampicillin (51/69), vancomycin (53/68), and cefotaxime (55/58). In the same period, the care units with the most antimicrobial use (expressed as minimum/ maximum DOTs per 1000 PDs) were hematology-oncology (2529/2723), pediatrics (1006/1408), and pediatric intensive care (1328/1717). Conclusions: This study showed generally stable consumption of antimicrobials from 2015/16 to 2018/19 in a Canadian mother-and-child university hospital centre. Although consumption was also stable within drug groups (antibiotics, antivirals, and antifungals), there were important changes over time for some individual drugs. Several factors may explain these variations, including disruptions in supply, changes in practice, and changes in the prevalence of infections. Surveillance of antimicrobial use is an essential component of an antimicrobial stewardship program. RÉSUMÉ Contexte : La gestion des antimicrobiens est une pratique courante dans les centres hospitaliers afin de réduire l’utilisation inappropriée des antimicrobiens et le risque de résistance. Objectif : Décrire l’évolution de l’utilisation des antimicrobiens dans un centre hospitalier universitaire de 2015-16 à 2018-19. Méthodes : Dans cette étude rétrospective, descriptive et transversale, les dossiers pharmacologiques ont servi à déterminer le nombre de jours de traitement (NJT) et la dose définie journalière (DDD) par 1000 jours-présence (JP) pour chaque antimicrobien et pour chaque unité de soins par année de l’étude. Pour chaque mesure, on a également comparé le ratio de 2018-19 à celui de 2015-16, qui est exprimé en proportion; lorsque la valeur de cette proportion était ≤ 0,8 ou ≥ 1,2, ce qui indiquait un changement important durant la période de l’étude, une note explicative a été attribuée par consensus. Résultats : Durant la période à l’étude, 94 antimicrobiens ont été disponibles dans notre centre : 70 antibiotiques (dont les antiparasitaires et les antituberculeux), 14 antiviraux et 10 antifongiques. Le nombre total de NJT par 1000 JP a diminué de 904 en 2015-16 à 867 en 2018-19. Les cinq antimicrobiens utilisés le plus fréquemment et présentés en minimum / maximum de NJT par 1000 JP étaient les suivants : piperacilline-tazobactam (78/105), trimethoprim-sulfamethoxazole (74/84), ampicilline (51/69), vancomycine (53/68) et cefotaxime (55/58). Pendant la même période, les unités de soins qui faisaient la plus grande utilisation d’antimirobiens (exprimée en minimum / maximum de NJT par 1000 JP) étaient hématologie-oncologie (2529/2723), pédiatrie (1006/1408) et soins intensifs pédiatriques (1328/1717). Conclusions : Cette étude démontre une consommation stable d’antimicrobiens entre 2015-16 et 2018-19 dans un centre hospitalier universitaire mère-enfant canadien. Malgré le fait que la consommation entre les groupes d’antimicrobiens (antibiotiques, antiviraux, antifongiques) était stable, on a constaté d’importantes variations concernant certains médicaments individuels. Plusieurs facteurs peuvent expliquer cette variation, notamment des ruptures d’approvisionnement, des changements de pratique et des changements dans la prévalence d’infections. La surveillance de la consommation des antimicrobiens est une partie essentielle de tout programme d’antibiogouvernance.

Abstract Background Documenting the actions and effects of an antimicrobial stewardship program (ASP) is essential for quality improvement and support by hospital leadership. Thus, our ASP tallies the number of charts reviewed, types of recommendations, how and to whom they were communicated, whether they were followed, and any effects on antimicrobial days of therapy. Here we describe how we customized the electronic medical record at our institution to facilitate our workflow and data analysis, while highlighting principles that should be adaptable to other ASPs. Methods The documentation system involves the creation of a novel and intuitive ASP form in each chart reviewed and 2 mutually exclusive tracking systems: 1 for active forms to facilitate the daily ASP workflow and 1 for finalized forms to generate cumulative reports. The ASP form is created by the ASP pharmacist, edited by the ASP physician, reopened by the pharmacist to assess whether the recommendation was followed and to quantify any antimicrobial days avoided or added, then reviewed and finalized by the ASP physician. Active forms are visible on a real-time “MPage,” whereas all finalized forms are compiled nightly into 65 informative tables and associated graphs. Results and Conclusions This system and its underlying principles have automated much of the documentation, facilitated follow-up of interventions, improved the completeness and validity of recorded data and analysis, enabled our ASP to expand its activities, and been associated with decreased antimicrobial usage, drug resistance, and Clostridioides difficile infections.

Positive outcomes of antimicrobial stewardship programs in the inpatient setting are well documented, but the benefits for patients not admitted to the hospital remain less clear. This report describes a retrospective case–control study of patients discharged from the emergency department (ED) with subsequent positive cultures conducted to determine whether integrating antimicrobial stewardship responsibilities into practice of the emergency medicine clinical pharmacist (EPh) decreased times to positive culture follow-up, patient or primary care provider (PCP) notification, and appropriateness of antimicrobial therapy. Pre- and post-implementation groups of an EPh-managed antimicrobial stewardship program were compared. Positive cultures were identified in 177 patients, 104 and 73 in pre- and post-implementation groups, respectively. Median time to culture review in the pre-implementation group was 3 days (range 1-15) and 2 days (range 0-4) in the post-implementation group ( P = .0001). There were 74 (71.2%) and 36 (49.3%) positive cultures that required notification in the pre- and post-implementation groups, respectively, and the median time to patient or PCP notification was 3 days (range 1-9) and 2 days (range 0-4) in the 2 groups ( P = .01). No difference was seen in the appropriateness of therapy. In conclusion, EPh involvement reduced time to positive culture review and time to patient or PCP notification when indicated.

Abstract Introduction/Purpose An acute drop in highly dialyzable antihypertensive drug levels is considered to be one of the pathophysiological mechanisms of blood pressure rise during hemodialysis (HD). The study aimed to assess the prevalence of intradialytic hypertension (ID-HTN) and identify the most significant risk factors of its development. Methods We performed a retrospective case-control single-center study of HD patients from January 1st, 2014 to December 30th, 2016. Baseline evaluation included recording of antihypertensive medications with a focus on dialyzability of drugs. ID-HTN was defined as an increase in systolic blood pressure more than 10 mmHg after HD session. Results We enrolled 131 HD patients (52% males, median age 55.7 [53.5; 58.0] years, dialysis vintage 59.3 [51.8; 66.8] months). 79 patients suffered from ID-HTN. Highly dialyzable drugs were used in 61% of patients, most often – in 68% of cases – in the group of beta-blockers, less often among inhibitors of angiotensin-converting enzyme (32%). ID-HTN was associated with use of beta-blockers (Spearman's rank correlation coefficient (r)=0.212; p=0.015), moxonidine (r=0.313; p=0.001) and highly dialyzable drugs (r=0.440; p&lt;0.0001). Using the identified risk factors, a prediction model for ID-HTN based on logistic regression was constructed: y = −1.015 + 1.720 × highly dialyzed drugs + 0.993 × moxonidine; p = exp (y) / (1 + exp (y)). Table 1 displays actual and predicted values on the sample of HD patients. Conclusion In present study 60% of dialysis patients suffered from ID-HTN. Drugs with high dialysis clearance were widely used (61%) in dialysis population. Highly dialyzable drugs were associated with increased risk of ID-HTN (OR 5.585; 95% CI 2.49–12.54; p&lt;0.0001). The low specificity (65.4%) of the prediction model limits its use in clinical practice. Figure 1 shows the covariate-adjusted ROC curve by logistic regression model.

Abstract Background Antimicrobial stewardship program (ASP) interventions have been reported to reduce unnecessary antimicrobial use (AMU). In this study, we investigated the difference in the use of carbapenems by ASP intervention in Japanese healthcare facilities. Methods Data on two components of AMU and ASP registered in Japan Surveillance for Infection Prevention and Healthcare Epidemiology (J-SIPHE) from January to December 2019, were used. Facilities with an infection control team in addition to an antimicrobial stewardship team responsible for the proper use of antimicrobial agents were included in the study. AMU data (such as DOT [Days of Therapy / 100 patient days]) are entered semi-automatically from medical fee statement (receipt) file at each facility. ASP intervention is divided into four categories 1) pre-authorization, 2) prospective audit and feedback (PAF), 3) PAF and required notification (RN), 4) RN. The Kruskal-Wallis test is performed to see overall difference and the Dunn test with the Bonferroni correction is done for each pair of categories. Results A total of 114 hospitals were included in the analysis. The median number of beds at participating facilities were 430 [IQR: 281–602], the median average hospital stay was 13.0 days [IQR: 11.4–15.2] and total number of inpatients per month was 10087 [6247–14536]. PAF and RN were the most common ASP interventions for carbapenems (62.5%), followed by RN (33.6%). The median DOT [IQR] of participating facilities were 2.1 [1.2–3.1] and 1) 0.7 [0.2–1.1], 2) 2.7 [2.1–3.4], 3) 2.1 [1.4–3.1] and 4) 2.0 [1.2–3.5] by ASP categories. There are significant differences between 1) and 2), 1) and 3), and 1) and 4) (p=0.014, p&lt; 0.01 and p&lt; 0.01, respectively) while the differences between 2) and 3), 2) and 4), and 3) and 4) are not significant (p=1.00). Table 1. Summary statistics of healthcare facilities by ASP Interventions Figure 1. DOT by ASP Interventions Conclusion Only 3.5% of ASP interventions belong to 1) pre-authorization category and this might be due to the complexity of registration process. This category was found to have the lowest DOT among all ASP interventions in Japanese healthcare facilities. The variances of DOT were especially large in categories 3) and 4), and more detailed analyses would be necessary to evaluate their efficacies accurately.
