The Impact

Abstract Background Antimicrobial stewardship program (ASP) surveillance at our hospital is supplemented by an internally developed surveillance database. In 2013, the database incorporated a validated, internally developed, prediction rule for patient mortality within 30 days of hospital admission. This study describes the impact of an expanded ASP review in patients at the highest risk for mortality. Methods This retrospective, quasi-experimental study analyzed adults who received antimicrobials with the highest mortality risk score. Study periods were defined as 2011 – Q3 2013 (historical group) and Q4 2013 – 2018 (intervention group). Primary and secondary outcomes were assessed for confounders and analyzed using both unadjusted and propensity score weighted analyses. Interrupted time-series analyses also analyzed key outcomes. Results A total of 3,282 and 5,456 patients were included in the historical and intervention groups, respectively. There were significant reductions in median antimicrobial duration (5 vs. 4 days; p < 0.001), antimicrobial DOTs (8 vs. 7; p < 0.001), antimicrobial cost ($96 vs. $85; p = 0.003), length of stay (LOS) (6 vs. 5 days; p < 0.001), intensive care unit (ICU) LOS (3 vs. 2 days; p < 0.001), total hospital cost ($10,946 vs. $9,119; p < 0.001), healthcare facility-onset vancomycin-resistant Enterococcus (HO-VRE) spp. (1.3% vs. 0.3%; p = < 0.001) and HO-VRE infections (0.6% vs. 0.2%; p = 0.018) in the intervention cohort. Conclusion Reductions in antimicrobial use, hospital and ICU LOS, HO-VRE, HO-VRE infections, and costs were associated with incorporation of a novel mortality prediction rule to guide ASP surveillance and intervention.

Abstract Background Antimicrobial stewardship team (AST) surveillance at our hospital is facilitated by an internally-developed database. In 2013, the database was expanded to incorporate a validated internally-developed prediction rule for patient mortality within 30 days of hospital admission. AST prospective audit and feedback expanded to include all antimicrobials prescribed in patients with the highest risk for mortality determined by risk score. This study describes the impact of an expanded AST review in patients at the highest risk for mortality. Methods This retrospective, observational study analyzed all adult patients with the highest mortality risk score who received antimicrobials not historically captured via AST review. Patients were identified through administrative and AST databases. Study periods were defined as 2011 – Q3 2013 (historical group) and Q4 2013 – 2018 (intervention group). Primary and secondary outcomes were assessed for confounders including demographic data and infection-related diagnoses. Outcomes were assessed using both unweighted and propensity score weighted versions of the t-test or Wilcoxon rank-sum test for continuous variables and the chi-squared test or Fisher’s Exact test for discrete variables. Results A total of 2,852 and 5,460 patients were included in the historical and intervention groups, respectively. After adjusting for demographic and clinical characteristics, there were significant reductions in median antimicrobial duration (5 vs. 4, P = 0.002), antimicrobial days of therapy (7 vs. 7, P = 0.001), length of stay (LOS) (6 vs. 5 days, P = 0.001), intensive care unit (ICU) LOS (3 vs. 2 days, P < 0.001), and total hospital cost ($11,017 vs. $9,134, P < 0.001) in the intervention cohort. There were no significant differences observed in 30-day mortality or 30-day readmissions. Secondary analyses showed significant decreases in fluroquinolone and intravenous vancomycin utilization between cohorts. Conclusion Reductions in antimicrobial use, inpatient and ICU length of stay, and total hospital costs were observed in a cohort of patients following incorporation of a novel mortality prediction rule to guide AST surveillance.

Objective The primary objectives were to evaluate the prescriber acceptance rate of Antimicrobial Stewardship Program (ASP) pharmacist recommendation to de-escalate/discontinue meropenem, and estimate the difference in duration of meropenem therapy. The secondary objective was to determine incidence of adverse events in the two groups. Methods It was a retrospective study. All patients admitted to Gwinnett Medical Center and receiving meropenem from January–November 2015 were included in the study. Exclusion criteria were: patients admitted to intensive care unit, one-time dose, infectious disease consultation, and age <18 years. Electronic medical records were reviewed for data collection. The control group consisted of patients from January–July 2015 when there was no ASP pharmacist. The intervention group consisted of patients from August–November 2015 during which period the ASP pharmacist recommended de-escalation/discontinuation of meropenem based on culture and sensitivity results. Results A total of 41 patients were studied, 21 in the control group and 20 in the intervention group. There was no significant difference in baseline characteristics in the two groups and in terms of prior hospitalization or antibiotic use (within 90 days) and documented or suspected MDRO infection at the time of admission. De-escalation/discontinuation was suggested in 16/20 patients in the intervention group (80%), and intervention was accepted in 68%. The mean duration of therapy was significantly decreased in the intervention group (5.6 days vs. 8.1 days, p =0.0175). Two patients had thrombocytopenia (unrelated to meropenem), and none of the patients had seizure. Conclusion Targeted antibiotic review is an effective ASP strategy, which significantly decreases the duration of meropenem therapy.

Abstract Background Antimicrobial stewardship programs allow a reduction in antibiotic prescription and, consequently, in the incidence of multidrug-resistance infections. However, the impact on nosocomial candidemia is still unclear. Methods The present study is an interrupted time-series (ITS) before-after study, based on an ecological time-trend analysis. Since 2014, an antimicrobial stewardship program (ASP) has been implemented at an Italian tertiary-care hospital. The first objective of the program was to reduce carbapenem consumption, through an active and computerized surveillance of all carbapenem prescriptions, each of which was checked and validated by ID specialists always after audit of the cases with treating physicians. We retrospectively evaluated the changing in the consumption of antimicrobials, carbapenems, and in the incidence of candidemia, during two study periods: before (2007–2013) and after (2014–2018) the implementation of the ASP. Results The implementation of ASP was followed by a significant decrease in antibiotic consumption, which was consistent through the following 5 years. At the end of the study, total antibiotic consumption has decreased by 38.476 DDDs per 100 patient-days (PDs) per quarter (95% CI: −21.784 to −55.168; P < 0.001) and carbapenems decreased by 4.452 DDD per 100 PDs per quarter (95% CI: −3.658 to −5.246; P = 0.001). After 5 years of ASP, incidence of candidemia decreased by 2.034 episodes per 1,000 PDs per quarter (95% CI: −0.738 to −3.330; P = 0.003), decreasing, at the end of 2018, by 53% compared with the expected value if the program had not been implemented. Conclusion At our Institution, the ASP had a positive impact on the consumption of carbapenems, and antimicrobials. The incidence of candidemia was also favorably affected by the program, reversing the trend after 2014. The ASP, even if not directly targeted to fungal infections, indirectly caused a reduction in the incidence of candidemia, probably reducing the number of patients colonized by Candida spp. Disclosures All authors: No reported disclosures.

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.

Abstract Purpose The development of an inpatient antimicrobial stewardship program (ASP) in an integrated healthcare system is described. Summary With increasing national focus on reducing inappropriate antimicrobial use, state and national regulatory mandates require hospitals to develop ASPs. In 2015, BJC HealthCare, a multihospital health system, developed a system-level, multidisciplinary ASP team to assist member hospitals with ASP implementation. A comprehensive gap analysis was performed to assess current stewardship resources, activities and compliance with CDC core elements at each facility. BJC system clinical leads facilitated the development of hospital-specific leadership support statements, identification of hospital pharmacy and medical leaders, and led development of staff and patient educational components. An antimicrobial-use data dashboard was created for reporting and tracking the impact of improvement activities. Hospital-level interventions were individualized based on the needs and resources at each facility. Hospital learnings were shared at bimonthly system ASP meetings to disseminate best practices. The initial gap analysis revealed that BJC hospitals were compliant in a median of 6 ASP elements (range, 4–8) required by regulatory mandates. By leveraging system resources, all hospitals were fully compliant with regulatory requirements by January 2017. Conclusion BJC’s ASP model facilitated the development of broad-based stewardship activities, including education modules for patients and providers and clinical decision support, while allowing hospitals to implement activities based on local needs and resource availability.

AbstractBackgroundAntimicrobial stewardship programs are effective in optimizing antimicrobial prescribing patterns and decreasing the negative outcomes of antimicrobial exposure, including the emergence of multidrug-resistant organisms. In dialysis facilities, 30%–35% of antimicrobials are either not indicated or the type of antimicrobial is not optimal. Although antimicrobial stewardship programs are now implemented nationwide in hospital settings, programs specific to the maintenance dialysis facilities have not been developed.ObjectiveTo quantify the effect of an antimicrobial stewardship program in reducing antimicrobial prescribing.Study design and settingAn interrupted time-series study in 6 outpatient hemodialysis facilities was conducted in which mean monthly antimicrobial doses per 100 patient months during the 12 months prior to the program were compared to those in the 12-month intervention period.ResultsImplementation of the antimicrobial stewardship program was associated with a 6% monthly reduction in antimicrobial doses per 100 patient months during the intervention period (P=.02). The initial mean of 22.6 antimicrobial doses per 100 patient months decreased to a mean of 10.5 antimicrobial doses per 100 patient months at the end of the intervention. There were no significant changes in antimicrobial use by type, including vancomycin. Antimicrobial adjustments were recommended for 30 of 145 antimicrobial courses (20.6%) for which there were sufficient clinical data. The most frequent reasons for adjustment included de-escalation from vancomycin to cefazolin for methicillin-susceptible Staphylococcus aureus infections and discontinuation of antimicrobials when criteria for presumed infection were not met.ConclusionsWithin 6 hemodialysis facilities, implementation of an antimicrobial stewardship was associated with a decline in antimicrobial prescribing with no negative effects.
