The Impact

Abstract Background The impact of formalized, interdisciplinary antimicrobial stewardship program (ASP) rounds in the intensive care unit (ICU) setting has not been well described. Methods We performed a two-arm, cluster-randomized, crossover quality improvement study over 8 months to compare the impact of weekly ICU rounds with an ASP team vs. usual care. The primary outcome was antibiotic use (AU) in days of therapy (DOT) per 1,000 days present during and following ICU exposure. Our cohort consisted of ICU patients in 5 ICUs in Duke University Hospital. The unit of randomization was rounding team, which corresponded to half of the ICU beds in each unit. Each team was randomized to the intervention for 4 months followed by usual care for 4 months (or vice versa). The intervention involved multidisciplinary review of eligible patients to discuss antibiotic optimization. Patients not on antibiotics, followed by infectious diseases, post-transplant, on ECMO, or with a ventricular assist device were excluded from review. Intervention impact was assessed with multivariable negative binomial regression rate ratios (RR). AU was assessed over time before and after the study period to assess global and unit-level trends. Results We had 4,683 ICU-exposed patients. Intervention effect was not significant for the primary outcome (table). The intervention order was not significant in the model. Eligible patients were lower in the cardiothoracic ICU (CTICU) compared with other units (table); the intervention led to a significant decrease in AU when the CTICU was removed (RR = 0.93 [0.89–0.98], P = 0.0025). Intervention impact was differential among ICUs, with the greatest effect in surgical and least in CTICU (table). nit-level AU decreased in all ICUs, driven by 4 of the 5 ICUs (table, figure). Conclusion The effect of ASP rounds on AU was mixed for different types of ICUs. The direct effect on AU (intervention vs. control) was small because the analysis addressed the whole ICU population and thus was subject to biases from exposures after an ICU stay, ineligible patients, and lack of blinding. However, we observed an overall decline in AU during the study period, which we believe represents indirect effects of increased ASP activity and awareness. Additional ASP resources to round more than weekly may result in greater effect. Disclosures All Authors: No reported Disclosures.

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 < .001) post-intervention, and median time to IPT was reduced by 21.2 hours (P < .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 < .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.

The effectiveness of antimicrobial stewardship programs (ASP) in reducing antimicrobial use (AU) in children has been proved. Many interventions have been described suitable for different institution sizes, priorities, and patients, with surgical wards being one of the areas that may benefit the most. We aimed to describe the results on AU and length of stay (LOS) in a pre-post study during the three years before (2014–2016) and the three years after (2017–2019) implementation of an ASP based on postprescription review with feedback in children and adolescents admitted for appendix-related intraabdominal infections (AR-IAI) in a European Referral Paediatric University Hospital. In the postintervention period, the quality of prescriptions (QP) was also evaluated. Overall, 2021 AR-IAIs admissions were included. Global AU, measured both as days of therapy/100 patient days (DOT/100PD) and length of therapy (LOT), and global LOS remained unchanged in the postintervention period. Phlegmonous appendicitis LOS (p = 0.003) and LOT (p < 0.001) significantly decreased, but not those of other AR-IAI diagnoses. The use of piperacillin–tazobactam decreased by 96% (p = 0.044), with no rebound in the use of other Gram-negative broad-spectrum antimicrobials. A quasisignificant (p = 0.052) increase in QP was observed upon ASP implementation. Readmission and case fatality rates remained stable. ASP interventions were safe, and they reduced LOS and LOT of phlegmonous appendicitis and the use of selected broad-spectrum antimicrobials, while increasing QP in children with AR-IAI.

Abstract Objectives To assess the effects of BWCs on prosecutorial and court-related charge outcomes across multiple crime types, including domestic violence charges, crimes committed against police officers, and drug/alcohol charges. Methods A cluster-randomized controlled trial with 22 spatiotemporal police units assigned to BWCs and 17 assigned to control conditions. Data from the State Attorney’s Office were used to track convictions, adjudication withheld dispositions, and declined prosecutions for both experimental and control charges. A series of multilevel logistic and negative binomial regression models were used to estimate the effect of BWC footage on charge outcomes. Outcomes BWCs led to a significantly higher proportion of crimes against police officers resulting in convictions or adjudication withheld outcomes, and a significantly higher proportion of domestic violence charges resulting in convictions alone, compared to control charges. However, after the clustering effect was taken into account, only the effect of BWCs on crimes against police officers remained statistically significant. Conclusion These early results suggest that BWCs have significant evidentiary value that varies by crime type. BWCs may be best suited to capture evidence of crimes committed against police officers and potentially in domestic violence offenses as well.

Abstract Background In an effort to minimize complications associated with over-utilization of antibiotics, many antimicrobial stewardship programs have incorporated an antibiotic time out (ATO). Despite the increasing adoption of the ATO, limited data are available to support its effectiveness. This study was designed to assess the impact of an automated ATO integrated into the electronic medical record (EMR) on the rate of antibiotic modification in patients receiving broad-spectrum antibiotic(s) for Gram-negative bacteremia (GNB). Methods This was a single-center retrospective cohort study of inpatients from January 2017 to June 2018 conducted at a large academic medical center. ATO was implemented on October 31, 2017. Adult patients with GNB who received at least 72 hours of a systemic antibiotic were included. Patients with neutropenia or polymicrobial infections were excluded. The primary outcome was the proportion of patients who received a modification of therapy within 24 hours of final culture results. Secondary outcomes included modification at any point in therapy, time to modification of therapy, time to de-escalation, and days of therapy of broad-spectrum antibiotics. Results There was a total of 88 patients who met inclusion criteria, 37 patients pre-ATO and 51 patients post-ATO. The primary outcome of modification of therapy within 24 hours of final culture results was not significantly different for patients in the pre-ATO and post-ATO groups (19% vs. 20%, P = 0.94, respectively). The secondary outcome of modification of therapy at any point in therapy was not significantly different between the two groups (62% vs. 66%, P = 0.67). Of the 47 patients who received a modification of therapy, the mean time to modification was significantly shorter in the post-ATO group (52.8 hours vs. 45.26 hours, P < 0.05,). All other secondary outcomes were not significantly different between study groups. Conclusion The ATO alert was not associated with a higher rate of antibiotic modification within 24 hours of culture results in patients with GNB, although there was a significant reduction in the time to antibiotic modification. Further efforts are needed to improve the time to modification and optimize antibiotic prescribing practices. Disclosures All authors: No reported disclosures.

ABSTRACT Interventions to optimize blood culture (BCx) practices in adult inpatients are limited. We conducted a before-after study evaluating the impact of a diagnostic stewardship program that aimed to optimize BCx use in a medical intensive care unit (MICU) and five medicine units at a large academic center. The program included implementation of an evidence-based algorithm detailing indications for BCx use and education and feedback to providers about BCx rates and indication inappropriateness. Neutropenic patients were excluded. BCx rates from contemporary control units were obtained for comparison. The primary outcome was the change in BCxs ordered with the intervention. Secondary outcomes included proportion of inappropriate BCx, solitary BCx, and positive BCx. Balancing metrics included compliance with the Centers for Medicare and Medicaid Services (CMS) SEP-1 BCx component, 30-day readmission, and all-cause in-hospital and 30-day mortality. After the intervention, BCx rates decreased from 27.7 to 22.8 BCx/100 patient-days (PDs) in the MICU (P = 0.001) and from 10.9 to 7.7 BCx/100 PD for the 5 medicine units combined (P < 0.001). BCx rates in the control units did not decrease significantly (surgical intensive care unit [ICU], P = 0.06; surgical units, P = 0.15). The proportion of inappropriate BCxs did not significantly change with the intervention (30% in the MICU and 50% in medicine units). BCx positivity increased in the MICU (from 8% to 11%, P < 0.001). Solitary BCxs decreased by 21% in the medicine units (P < 0.001). Balancing metrics were similar before and after the intervention. BCx use can be optimized with clinician education and practice guidance without affecting sepsis quality metrics or mortality.

Objective: Evaluate the relation of nursing workload, evaluated by the Nursing Activities Score (NAS), with the occurrence of Ventilator-associated Pneumonia (VAP) in an Intensive Care Unit (ICU) and the impact of VAP on hospitalization costs.Methods: Retrospective cohort study in Adult ICU of a high complexity Brazilian university hospital. The profile, outcomes, costs, and daily NAS from patients were collected. We also proposed some workload indicators based on NAS daily evaluation.Results: The study included 195 patients, 27.17% diagnosed with VAP. VAP was more prevalent in patients diagnosed with trauma on admission. The total costs of care were higher for VAP patients. In all multivariate models tested were predictive for VAP: the patient's intubation that occurs in days prior of the ICU admission day (higher risk if occurs in days prior the ICU admission day) and ventilation time prior ICU (higher risk if higher time). We found others predictors, but these were dependent on the model tested. Additional risk predictors were tracheostomy, propofol use, neuromuscular blocker use and the higher NAS from admission. The protective factors found were the percentage of adequacy of the assignment based in NAS that measure if the workload measured by the NAS was offered and the increment in NAS during the ventilation time.Conclusions: The offering of an adequate nursing work scale (adequate number of professionals for the care), as a function of the nursing workload measured by the NAS, could be effective in the reduction of VAP, hospital stay time and hospital costs.

Abstract Background Antibiotic stewardship program (ASP) implementation is paramount across the healthcare spectrum. Nursing homes represent a challenge due to limited resources, complexity of medical conditions, and less controlled environments. National statistics on ASP for long-term care facilities (LTCF) are sparse. Methods A pilot ASP was launched in August 2016 at a 270-bed nursing home with a 50-bed chronic ventilator-dependent unit. The program entailed a bundle of interventions including leadership engagement, a tracking and reporting system for intravenous antibiotics, education for caregivers, Infectious Disease (ID) consultant availability, and implementation of nursing protocols. Data were collected from pharmacy and medical records between January 2016 and March 2017, establishing pre-intervention and post-intervention periods. Collected data included days of therapy (DOT), antibiotic costs, resident-days, hospital transfers, and Clostridium difficile infection (CDI) rates. Variables were adjusted to 1,000 resident-days (RD) and findings between periods were compared by Mann–Whitney U test. Results A total of 47,423 resident-days and 1,959 DOT were analyzed for this study. Antibiotic use decreased from 54.5 DOT/1000 RD pre-intervention to 27.6 DOT/1000 RD post-intervention (P = 0.017). Antibiotic costs were reduced from a monthly median of US $17,113 to US $7,073 but was not statistically significant (P = 0.39). Analysis stratified by individual antibiotic was done for the five most commonly used antibiotics and found statistically significant reduction in vancomycin use (14.4 vs. 6.5; P = 0.023). Reduction was also found for cefepime/ceftazidime (6.9 vs. 1.3; P = 0.07), ertapenem (6.8 vs. 3.6; P = 0.45), and piperacillin/tazobactam (1.8 vs. 0.6; P = 0.38). Meropenem use increased (1.3 vs. 3.2; P = 0.042). Hospital transfers slightly trended up (6.73 vs. 7.77; P = 0.065), and there was no change in CDI (1.1 s 0.94; P = 0.32). Conclusion A bundle of standardized interventions tailored for LTCF can achieve successful reduction of antibiotic utilization and costs. Subsequent studies are needed to further determine the impact on clinical outcomes such as transfers to hospitals and CDI in these settings. Disclosures All authors: No reported disclosures.

Objective: To evaluate the impact of a pharmacist-driven initiative to optimize aldosterone antagonist use in patients with heart failure with reduced ejection fraction (HFrEF) at a large community hospital. Methods: This single-center, retrospective cohort study compared patients with heart failure before and after the implementation of the initiative. Data for pre- and postinitiative patients were retrospectively collected to assess patient characteristics and aldosterone antagonist use. The primary outcome was a composite of eligible patients with heart failure discharged on aldosterone antagonist therapy or with a documented reason for ineligibility before and after commencement of pharmacist-driven aldosterone antagonist initiative. Results: The preinitiative cohort included 96 patients and the postinitiative cohort contained 92 patients. When the 3 month pre- and postinitiative groups were assessed, the primary outcome was noted in 60 (63%) of 96 patients in the preinitiative group and 87 (95%) of 92 patients in the postinitiative group ( P < .0001). Conclusion: In patients with HFrEF, a pharmacist-driven aldosterone antagonist optimization initiative significantly increased appropriate prescribing and documentation for aldosterone antagonist therapy.

BACKGROUND Transitions in care are vulnerable periods in health care that can expose patients to preventable errors due to incomplete or delayed communication between health care providers. Transitioning critically ill patients from intensive care units (ICUs) to other patient care units (PCUs) is particularly risky, due to the high acuity of the patients and the diversity of health care providers involved in their care. Instituting structured documentation to standardize written communication between health care providers during transitions has been identified as a promising means to reduce communication breakdowns. We developed an evidence-informed, computer-enabled, ICU-specific structured tool—an electronic transfer (e-transfer) tool—to facilitate and standardize the composition of written transfer summaries in the ICUs of one Canadian city. The tool consisted of 10 primary sections with a user interface combination of structured, automated, and free-text fields. OBJECTIVE Our overarching goal is to evaluate whether implementation of our e-transfer tool will improve the completeness and timeliness of transfer summaries and streamline communications between health care providers during high-risk transitions. METHODS This study is a cluster-specific pre-post trial, with randomized and staggered implementation of the e-transfer tool in four hospitals in Calgary, Alberta. Hospitals (ie, clusters) were allocated randomly to cross over every 2 months from control (ie, dictation only) to intervention (ie, e-transfer tool). Implementation at each site was facilitated with user education, point-of-care support, and audit and feedback. We will compare transfer summaries randomly sampled over 6 months postimplementation to summaries randomly sampled over 6 months preimplementation. The primary outcome will be a binary composite measure of the timeliness and completeness of transfer summaries. Secondary measures will include overall completeness, timeliness, and provider ratings of transfer summaries; hospital and ICU lengths of stay; and post-ICU patient outcomes, including ICU readmission, adverse events, cardiac arrest, rapid response team activation, and mortality. We will use descriptive statistics (ie, medians and means) to describe demographic characteristics. The primary outcome will be compared within each hospital pre- and postimplementation using separate logistic regression models for each hospital, with adjustment for patient characteristics. RESULTS Participating hospitals were cluster randomized to the intervention between July 2018 and January 2019. Preliminary extraction of ICU patient admission lists was completed in September 2019. We anticipate that evaluation data collection will be completed by early 2021, with first results ready for publication in spring or summer 2021. CONCLUSIONS This study will report the impact of implementing an evidence-informed, computer-enabled, ICU-specific structured transfer tool on communication and preventable medical errors among patients transferred from the ICU to other hospital care units.
