The Impact

OBJECTIVETo describe the impact of rapid diagnostic microarray technology and antimicrobial stewardship for patients with Gram-positive blood cultures.DESIGNRetrospective pre-intervention/post-intervention study.SETTINGA 1,200-bed academic medical center.PATIENTSInpatients with blood cultures positive for Staphylococcus aureus, Enterococcus faecalis, E. faecium, Streptococcus pneumoniae, S. pyogenes, S. agalactiae, S. anginosus, Streptococcus spp., and Listeria monocytogenes during the 6 months before and after implementation of Verigene Gram-positive blood culture microarray (BC-GP) with an antimicrobial stewardship intervention.METHODSBefore the intervention, no rapid diagnostic technology was used or antimicrobial stewardship intervention was undertaken, except for the use of peptide nucleic acid fluorescent in situ hybridization and MRSA agar to identify staphylococcal isolates. After the intervention, all Gram-positive blood cultures underwent BC-GP microarray and the antimicrobial stewardship intervention consisting of real-time notification and pharmacist review.RESULTSIn total, 513 patients with bacteremia were included in this study: 280 patients with S. aureus, 150 patients with enterococci, 82 patients with stretococci, and 1 patient with L. monocytogenes. The number of antimicrobial switches was similar in the pre–BC-GP (52%; 155 of 300) and post–BC-GP (50%; 107 of 213) periods. The time to antimicrobial switch was significantly shorter in the post–BC-GP group than in the pre–BC-GP group: 48±41 hours versus 75±46 hours, respectively (P<.001). The most common antimicrobial switch was de-escalation and time to de-escalation, was significantly shorter in the post-BC-GP group than in the pre–BC-GP group: 53±41 hours versus 82±48 hours, respectively (P<.001). There was no difference in mortality or hospital length of stay as a result of the intervention.CONCLUSIONSThe combination of a rapid microarray diagnostic test with an antimicrobial stewardship intervention improved time to antimicrobial switch, especially time to de-escalation to optimal therapy, in patients with Gram-positive blood cultures.Infect Control Hosp Epidemiol 2016;1–6

The Impact

Background: Data are limited addressing anticoagulant reversal in obese patients using activated prothrombin complex concentrate (aPCC). Objective: Assess the impact of obesity on INR reversal with fixed aPCC dosing. Methods: Institutional review board–approved, retrospective cohort conducted in a large academic medical center. Patients 18 years or older who received fixed-dose aPCC for warfarin-associated hemorrhage were included. Patients who received aPCC for any other indications or who had no follow-up INR after aPCC administration were excluded. Patients with an INR of 5 or greater received 1000 units aPCC, whereas those with INR less than 5 received 500 units aPCC, per institutional protocol. Patients were stratified into obese and nonobese based on body mass index. Primary end point was INR reversal, defined as repeat INR of 1.4 or less within 4 hours following aPCC treatment, without a repeated dose. Secondary end points included percentage change in INR, proportion of patients requiring an additional dose of aPCC, bleeding complications, thrombotic complications, hospital length of stay, and in-hospital mortality. Results: 259 patients were included, of whom 83 were obese (32%). A significantly higher proportion of nonobese patients achieved an INR of 1.4 or less within 4 hours of treatment (169 [96.02%] vs 69 [83.13%]; P = 0.0004). There were no differences in any secondary end points. Conclusion and Relevance: When fixed-dose aPCC is used for warfarin reversal, obesity is associated with a significantly lower rate of INR reversal, without increased bleeding. This study adds to the limited amount of literature on aPCC dosing in obesity.

Abstract Background A candidemia treatment bundle (CTB) may increase adherence to guideline recommended candidemia management and improve patient outcomes. The purpose of this study was to evaluate the impact of a best practice alert (BPA) and order-set on optimizing compliance with all CTB components and patient outcomes. Methods A single center, pre-/post-intervention study was completed at Grady Health System from August 2015 to August 2017. Post-CTB intervention began August 2016. The CTB included a BPA that fires for blood cultures positive for any Candida species to treatment clinicians upon opening the patient’s electronic health record. The BPA included a linked order-set based on treatment recommendations including: infectious diseases (ID) and ophthalmology consultation, repeat blood cultures, empiric echinocandin therapy, early source control, antifungal de-escalation, intravenous to oral (IV to PO) switch, and duration of therapy. The primary outcome of the study was total adherence to the CTB. The secondary outcomes include adherence with the individual components of the CTB, 30-day mortality, and infection-related length of stay (LOS). Results Forty-five patients in the pre-group and 24 patients in the CTB group with candidemia were identified. Twenty-seven patients in the pre-group and 19 patients in the CTB group met inclusion criteria. Total adherence with the CTB occurred in one patient in the pre-group and threepatients in the CTB group (4% vs. 16%, P = 0.29). ID was consulted in 15 patients in the pre-group and 17 patients in the CTB group (56% vs. 89%, P = 0.02). Source control occurred in three and 11 patients, respectively (11% vs. 58% P &lt; 0.01). The bundle components of empiric echinocandin use (81% vs. 100%, P = 0.07), ophthalmology consultation (81% vs. 95%, P = 0.37), and IV to PO switch (22% vs. 32%, P = 0.5) also improved in the CTB group. Repeat cultures and antifungal de-escalation were similar among groups. Thirty-day mortality decreased in the CTB group by 10% (26% vs. 16%, P = 0.48). Median iLOS decreased from 30 days in the pre-group to 17 days in the CTB group (P = 0.05). Conclusion The CTB, with a BPA and linked order-set, improved guideline recommended management of candidemia specifically increasing the rates of ID consultation and early source control. There were quantitative improvements in mortality and iLOS. Disclosures All authors: No reported disclosures.

Abstract Background Recent data has shown a transition to oral (PO) antibiotics (ABX) for definitive treatment of uncomplicated bacteremia has similar efficacy compared to continuation of intravenous (IV) ABX, and reduces hospital length of stay (LOS). The purpose of this study was to evaluate the safety and efficacy of an antimicrobial stewardship pharmacist-driven, IV to PO ABX transition in clinically stable patients with uncomplicated bacteremia, and to determine the impact on hospital LOS. Methods This was a prospective, interventional study with concurrent controls, conducted at Cedars-Sinai Medical Center between November 2019 and April 2020. For patient recruitment, a report of all positive inpatient blood cultures was reviewed daily. For patients meeting study criteria, the treating provider was contacted to recommend an IV to PO ABX transition. The treating provider was responsible for making the final determination on ABX therapy. Patients continuing IV ABX served as the comparator group to those transitioning to PO. The primary outcome of interest was a composite of: 30-day, all-cause mortality, 30-day readmission due to infectious- or ABX-related complications, or 30-day recurrent infection with the same organism recovered. The second outcome of interest was overall hospital LOS and hospital LOS after the definitive ABX regimen was established. Results A total of 117 patients were evaluated; 69 patients met criteria for inclusion in the study (46 PO ABX / 23 IV ABX). Overall, baseline characteristics were similar between the groups. No difference was observed in the 30-day composite outcome (1 in each group), but the median, overall hospital LOS was three days shorter in the PO group. Furthermore, hospital LOS after the definitive ABX regimen was established was four days shorter in the PO group. Based on the differences in hospital LOS observed, the intervention was estimated to have resulted in approximately $819,200 cost-avoidance during the study period. Conclusion Similar to prior studies, our findings support the safety and effectiveness of an IV to PO ABX transition in clinically stable patients with uncomplicated bacteremia. Antimicrobial stewardship pharmacists can be leveraged to facilitate such a transition. Disclosures All Authors: No reported disclosures

Abstract Background High regulatory burden on hospital-onset (HO) infections has increased performance pressure on infection prevention programs. Despite the availability of comprehensive prevention guidelines, a major challenge has been communication with frontline staff to integrate appropriate prevention measures into practice. The objective of our study was to evaluate the impact of educational intervention on HO CAUTI rates and urinary catheter days. Methods At the University of Mississippi Medical Center, Infection prevention (IP) reports unit-based monthly HO infections via email to respective unit managers and ordering physician providers. Starting May 2018, IP assessed compliance to CAUTI prevention strategies per SHEA/IDSA practice recommendations (2014). HO CAUTI cases with noncompliance were labeled as “preventable” infections and educational justification was provided in the email report. No other interventions were introduced during the study period. CAUTI data were collected using ongoing surveillance per NHSN and used to calculate rates per 1,000 catheter days. One-way analysis of variance (ANOVA) was used to compare pre- and post-intervention data. Results Prior to intervention (July 2017–March 2018), HO CAUTI rate was 1.43 per 1,000 catheter days. In the post-intervention period (July 2018–March 2019), HO CAUTI rate decreased to 0.62 per 1,000 catheter days. Comparison of pre- and post-intervention rates showed a statistically significant reduction in HO CAUTIs (P = 0.04). The total number of catheter days reduced, but the difference was not statistically significant (8,604 vs. 7,583; P = 0.06). Of the 14 HO CAUTIs in post-intervention period, 64% (8/14) were reported preventable. The preventable causes included inappropriate urine culturing practice in asymptomatic patients (5) or as part of pan-culture without urinalysis (2), and lack of daily catheter assessment for necessity (1). Conclusion At our institute, regular educational feedback by IP to frontline staff resulted in a reduction of HO CAUTIs. Feedback measure improved accountability, awareness and engagement of frontline staff in practicing appropriate CAUTI prevention strategies. Disclosures All authors: No reported disclosures.

The Relationship

With emphasis on value-based health care, empiric models are used to estimate expected read-mission rates for individual institutions. The aim of this study was to determine the relationship between distance traveled to seek surgical care and likelihood of readmission in adult patients undergoing cardiac operations at a single medical center. All adults undergoing major cardiac surgeries from 2008 to 2015 were included. Patients were stratified by travel distance into regional and distant travel groups. Multivariable logistic regression models were developed to assess the impact of distance traveled on odds of readmission. Of the 4232 patients analyzed, 29 per cent were in the regional group and 71 per cent in the distant. Baseline characteristics between the two groups were comparable except mean age (62 vs 61 years, P < 0.01) and Caucasian race (59 vs 73%, P < 0.01). Distant travel was associated with a significantly longer hospital length of stay (11.8 vs 10.5 days, P < 0.01) and lower risk of readmission (9.5 vs 13.4%, P < 0.01). Odds of readmission was inversely associated with logarithm of distance traveled (odds ratio 0.75). Travel distance in patients undergoing major cardiac surgeries was inversely associated with odds of readmission.

Daily Sedation Interruption

Background: A multidisciplinary team updated an institution-specific pain, agitation, and delirium (PAD) guideline based on the recommendations from the Society of Critical Care Medicine (SCCM) PAD guidelines. This institution-specific guideline emphasized protocolized sedation with increased as needed boluses, and nonbenzodiazepine infusions, daily sedation interruption, and pairing of spontaneous awakening (SAT) and breathing trials (SBT). Objective: The purpose of this study was to evaluate the impact of implementation of a PAD guideline on clinical outcomes and medication utilization in an academic medical center intensive care unit (ICU). It was hypothesized that implementation of an updated guideline would improve clinical outcomes and decrease usage of benzodiazepine infusions. Methods: Pre-post retrospective chart review of 2417 (1147 pre, 1270 post) critically ill, mechanically ventilated adults in a medical/surgical ICU over a 2-year period (1 year pre and post guideline implementation). Results: After guideline implementation, average ventilation days was reduced (3.98 vs 3.43 days, P = .0021), as well as ICU and hospital length of stay (LOS) (4.79 vs 4.34 days, P = .048 and 13.96 vs 12.97 days, P = .045, respectively). Hospital mortality (19 vs 19%, P = .96) and acute physiology and chronic health evaluation (APACHE) IV scores (77.28 vs 78.75, P = .27) were similar. After guideline implementation, the percentage of patients receiving midazolam infusions decreased (422/1147 [37%] vs 363/1270 patients [29%], P = .0001). The percentage of patients receiving continuous infusion propofol (679/1147 [59%] vs 896/1270 [70%], P = .0001) and dexmedetomidine (78/1147 [7%] vs 147/1270 [12%], P = .0001) increased. Conclusions: Implementing a multidisciplinary PAD guideline utilizing protocolized sedation and daily sedation interruption decreased ventilation days and ICU and hospital LOS while decreasing midazolam drip usage.

Patient safety indicators (PSI), developed by the Agency for Healthcare Research and Quality, use administrative billing data to measure and compare patient safety events at medical centers. We retrospectively examined whether PSIs accurately reflect patients’ risk of mortality, hospital length of stay, and intensive care unit (ICU) requirements at an academic medical center. Surgical patient records with PSIs were reviewed between October 2011 and September 2012 at our urban academic medical center. Primary outcomes studied included mortality, hospital length of stay, and ICU requirements. Subset analysis was performed for each PSI and its association with the outcome measures. PSIs were more common among surgical patients who died as compared with those alive at discharge (35.3 vs 2.7 PSIs/100 patients, P < 0.01). Although patients who died with PSIs had shorter hospital courses, they had a significantly greater ICU requirement than those without a PSI (96.0 vs 61.1%, P < 0.01) and patients who were alive at discharge (96.0 vs 48.0%, P < 0.01). The most frequently associated PSIs with mortality were postoperative metabolic derangements (41.7%), postoperative sepsis (38.5%), and pressure ulcers (33.3%). PSIs occur at a higher frequency in surgical patients who die and are associated with increased ICU requirements.

Background: Numerous interventions have been used to reduce medication errors related to antiretroviral (ARV) therapy for hospitalized patients with HIV. Objective: This study assessed the impact of an antimicrobial stewardship (ASP) team intervention on reducing the rate of ARV therapy errors in patients admitted to an academic medical center. Methods: This observational, retrospective study included patients who received ARV therapy from June 2016 to December 2017. The primary outcome was evaluation of ASP team performance in detecting ARV medication errors in the inpatient setting. Errors were further categorized by type (interaction, dosing, regimen). The Mann-Whitney U test and χ2 tests were utilized to analyze continuous and categorical data, respectively. Results: Medication errors occurred in 51% of patients in the preintervention group (n = 152) and 48% of patients in the postintervention group (n = 203; P = 0.43). The most frequent medication error type was drug interactions in both groups, involving integrase strand transfer inhibitors and polyvalent cations (64% vs 67%). There was a significant difference between preintervention and postintervention groups regarding number of errors detected (13 vs 106, P < 0.001), corrected (12 vs 86, P < 0.001), and persisting at discharge (106 vs 18, P < 0.001). Conclusion and Relevance: Review of ARV regimens by an ASP team significantly decreased medication errors. Drug interactions are the most common medication error found in HIV-positive patients admitted to our academic center.

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 Guidelines for antimicrobial prophylaxis in surgery recommend cefazolin dose be adjusted based on patient weight. Adults weighing ≥120 kg should receive a 3 g dose, all other adult patients should receive a 2 g dose pre-operatively. To promote guideline adherence, an antimicrobial stewardship pharmacist-driven dose optimization intervention was implemented. Methods Retrospective, pre (February 1, 2017–March 31, 2017)/post (February 1, 2018–March 31, 2018) study evaluating the impact of a pharmacist-driven cefazolin dose optimization intervention at a large health system. An alert within the electronic health record notified pharmacists during order verification when cefazolin dose from a surgical prophylaxis order set did not match weight-based recommendations. All patients with cefazolin orders for surgical prophylaxis were included; pediatric and pregnant patients were excluded. Results Pre-group included 9,830 patients, post-group 10,025 patients. In both groups, the mean age was 58 years, mean weight 87 kg, and 8% of patients weighed ≥120 kg. Approximately 21% of patients were seen at the academic medical center, 8% at ambulatory surgery centers, and the remainder amongst 10 community hospitals. Most common surgical procedure types were orthopedic (26%), general surgery (21%) and urologic (10%). Primary cefazolin dose was 2 g in 89.8% vs. 88.7%, followed by 3 g 6.6% vs. 6.9% and 1 g in 3.9% vs. 4.4%, pre- and post-intervention, respectively. Overall adherence to weight-based cefazolin dosing was 92.2% pre-group and 92.4% post-group. In patients weighing ≥120 kg, adherence improved from 62% (514/827) to 71% (582/817) post-intervention, P < 0.001. Adherence was better both pre- and post-intervention when an order set was used (pre: order set 95.0% vs. no order set 85.9%, P < 0.001; post: order set 96.4% vs. no order set 84.8%, P < 0.001). There were no differences between surgical services or hospital locations. Investigation of guideline nonadherent cases found order sets without updated dosing recommendations and allowed for targeted education efforts. Conclusion Overall adherence to cefazolin weight-based dosing recommendations for surgical prophylaxis was high, especially with the use of order sets. Pharmacist-driven dose optimization intervention improved guideline adherence in patients weighing ≥120 kg. Disclosures All authors: No reported disclosures.
