Abstract Background Timely effective therapy in multi-drug resistant (MDR) Pseudomonas (PsA) infections has a direct impact on patient survival. We aimed to determine the impact of diagnostic and antimicrobial stewardship (AMS) on time-to-appropriate therapy (TAP) and clinical outcomes of patients with MDR PsA infections utilizing novel beta-lactam/beta-lactamase inhibitors (BL/BLIs). Methods Retrospective cohort study of adult patients with MDR PsA infections at a 1,500-bed University-affiliated public hospital in Miami, Florida who received ≥72 hours of ceftazidime-avibactam (C/A) or ceftolozane-tazobactam (C/T). During the pre-intervention period (12/2017-12/2018), additional susceptibilities for C/A and C/T were performed upon providers’ request. In the post intervention period (01/2019 – 12/2019), we implemented automatic reflex algorithms (Figure 1) for faster identification and susceptibilities for MDR PsA, including carbapenemase producers. Results were communicated in real-time to the AMS team. Figure 1. Reflex Testing Algorithm for MDR Pseudomonas Isolates from Any Source Results Seventy-six patients were included; median age was 56 years (IQR 37.5–67.0), 40 (52.6%) were in an intensive care unit at time of culture collection; median APACHE II score was 20 (IQR 15.0 – 26.0). Three isolates were carbapenemase producers (VIM = 2; KPC = 1). The most common infections were pneumonia (56.6%) and bacteremia (18.4%). We found a significant decrease in median TAP (120.1 [IQR 82.5–164.6] vs 75.9 [IQR 51.3–101.7] hours, p = 0.003). Median time from culture collection to final susceptibility results was shorter in the post-intervention group (122.2 vs 90.5 hours; p < 0.001). Median length-of-stay after culture collection was numerically lower in the post-intervention group (26.0 [11.6–59.4] vs 19.7 [12.9–37.8] days; p = 0.33). Controlling for ICU admission, our intervention was not associated with decreased 30-day inpatient mortality (OR = 1.62, 95% CI 0.45–5.79). Conclusion Our study identified an improvement in TAP in MDR PsA infections with implementation of diagnostic and AMS initiatives. In an adequately powered study, our intervention could potentially impact patient survival through timely initiation of effective therapy with novel BL/BLIs.

Background: Limited sample size and disparate outcome measures can hinder the ability of antimicrobial stewardship programs to assess the utility of their quality improvement interventions. Desirability of outcome ranking (DOOR) is a novel methodology that incorporates multiple outcomes into a single value to more comprehensively compare therapeutic strategies. The objective of this study was to apply DOOR to a single center antibiotic stewardship intervention. Methods: A pre- and post-interventional study was conducted evaluating the impact of prospective pharmacist review of rapid molecular diagnostic testing (RDT) of blood cultures on antibiotic optimization. Outcomes included the percentage of patients who were switched to appropriate therapy, the time to appropriate therapy, and the percentage of patients who had missed de-escalation opportunities. Results: A total of 19 and 29 patients were included in the final analysis. The percentage of patients reaching appropriate therapy was 84% (16/19) and 97% ([28/29], p = 0.16) in the pre-intervention and post-intervention groups respectively. Median time to appropriate therapy was 26 hours and 36 minutes (IQR 13:05-50:45) and 22:40 (IQR 3:42-48:23, p = 0.32), respectively. One missed de-escalation opportunity was identified in the post-intervention group (0% vs 3%, p = 1.00). DOOR analysis indicated that the probability of a better outcome for the post-intervention group than the pre-intervention group was 58% (95% CI 54-62). Conclusion: In this analysis, DOOR revealed a benefit that would not have been apparent with traditional outcomes assessments. Antimicrobial stewardship programs conducting quality improvement studies should consider incorporating DOOR into their methodology.

SummaryObjective: Based on US. Centers for Disease Control and Prevention recommendations, New York State enacted legislation in 2010 requiring healthcare providers to offer non-targeted human immunodeficiency virus (HIV) testing to all patients aged 13–64. Three New York City adult emergency departments implemented an electronic alert that required clinicians to document whether an HIV test was offered before discharging a patient. The purpose of this study was to assess the impact of the electronic alert on HIV testing rates and diagnosis of HIV positive individuals.Methods: During the pre-intervention period (2.5–4 months), an electronic “HIV Testing” order set was available for clinicians to order a test or document a reason for not offering the test (e.g., patient is not conscious). An electronic alert was then added to enforce completion of the order set, effectively preventing ED discharge until an HIV test was offered to the patient. We analyzed data from 79,786 visits, measuring HIV testing and detection rates during the pre-intervention period and during the six months following the implementation of the alert.Results: The percentage of visits where an HIV test was performed increased from 5.4% in the pre-intervention period to 8.7% (p<0.001) after the electronic alert. After the implementation of the electronic alert, there was a 61% increase in HIV tests performed per visit. However, the percentage of patients testing positive per total patients-tested was slightly lower in the post-intervention group than the pre-intervention group (0.48% vs. 0.55%), but this was not significant. The number of patients-testing positive per total-patient visit was higher in the post-intervention group (0.04% vs. 0.03%).Conclusions: An electronic alert which enforced non-targeted screening was effective at increasing HIV testing rates but did not significantly increase the detection of persons living with HIV. The impact of this electronic alert on healthcare costs and quality of care merits further examination.Citation: Schnall R, Liu N, Sperling J, Green R, Clark S, Vawdrey D.

Background: Inpatient HIV-related medication errors occur in up to 86% of patients. Objective: To evaluate the number of antiretroviral therapy (ART)- and opportunistic infection (OI)-related medication errors following the implementation of pharmacist-directed interventions. Methods: This quasi-experiment assessed adult patients with HIV who received ART, OI prophylaxis, or both from December 1, 2014, to February 28, 2017 (pre-intervention) or December 1, 2017, to February 28, 2018 (post-intervention). Pre-intervention patients were assessed retrospectively; verbal and written education were provided (intervention); prospective audit and feedback was conducted for post-intervention patients. The primary outcome was rate of ART errors between groups. Secondary outcomes included rate of OI errors, time to resolution of ART and OI errors, types of errors, and rate of recommendation acceptance. Results: Sixty-seven patients were included in each group. ART errors occurred in 44.8% and 32.8% ( P = .156), respectively. OI prophylaxis errors occurred in 11.9% versus 9% ( P = .572), respectively. Medication omission decreased significantly in the post-intervention group (31.3% vs 11.9%; P = .006). Pharmacist-based interventions increased in the post-intervention group (6.3% vs 52.9%; P = .001). No statistical difference was found in time to error resolution (72 vs 48 hours; P = .123), but errors resolved during admission significantly increased (50% vs 86.8%; P < .001). No difference was found in rate of intervention acceptance (100% vs 97%). Conclusion and Relevance: ART and OI prophylaxis errors resolved a day faster in the pharmacist-led, post-intervention period, and there was a trend toward error reduction. Future interventions should target prescribing errors on admission using follow-up education and evaluation of medication reconciliation practices in HIV-infected patients.

Background and Purpose: There is growing interest in methods for early rehabilitation in patients with acute neurologic conditions. The purpose of this study was to identify whether increased coordination between the physical therapist and an attending cerebrovascular neurosurgeon through daily multidisciplinary rounds would correlate with positive changes in overall care. Hypothesis: We evaluated the hypothesis that a physical therapist participating in cerebrovascular neuroscience rounds would decrease the time to initial physical therapy (PT) consult, decrease hospital length of stay (LOS), decrease Intensive Care Unit (ICU) LOS, and decrease ventilator days. Methods: A retrospective review was performed of 235 patients who were admitted to the neuroscience service under a single cerebrovascular neurosurgeon over a 16-month period (April 2014 through July 2015) in a level-I trauma hospital. The study consisted of an eight-month pre-intervention period (n=117) where the physical therapist did not attend physician rounds and an eight-month post-intervention period (n=118). Results: In the post-intervention group the PT assessment occurred on average 1.57 days sooner than before the physical therapist participated in neuroscience physician rounds (p<0.001). Hospital LOS decreased by an average of 3.46 days (p=0.04) and ICU LOS decreased on average by 1.83 days (p=0.05) in the post-intervention group. Ventilator days decreased on average by 0.55 days, which was not statistically significant (p=0.26). Conclusions: In conclusion, daily coordination with multidisciplinary rounds between the physician and the physical therapist was associated with decreased time to initial PT assessment, decreased hospital LOS, and decreased ICU LOS in the neuroscience population.

Abstract Background In India, Candida bloodstream infections have a reported incidence of 1–12 per 1,000 admissions and a mortality rate of up to 60%. Antimicrobial stewardship programs (ASP) can improve quality of care and clinical outcomes. This study evaluates the impact of a comprehensive candidemia ASP bundle in a hospital in southern India with an established stewardship program. Methods A single-center, pre-post quasi-experimental study was conducted at a tertiary-care center in southern India to analyze the impact of an ASP care bundle for the management of adults with candidemia. During the intervention period (October 2017–December 2018), the ASP provided recommendations to providers in accordance with the 2016 IDSA Guidelines for the Management of Candidemia, which included the following bundle: (1) appropriate selection and dosing of antifungal therapy; (2) repeat blood cultures every 48 hours until clearance; (3) removal of central venous catheters and other potential removable foci of infection; (4) echocardiogram; (5) ophthalmologic evaluation; and (6) appropriate duration of therapy. The primary outcome was initiation of appropriate antifungal therapy. Additional clinical outcomes were also compared with a historical cohort. Results One hundred and four patients with candidemia were included: 52 in the pre-intervention and 52 in the post-intervention group. Overall, baseline demographics were similar between the two groups (Table 1). Candida tropicalis (26.9%) and Candida parapsilosis (29.8%) were the most common causes of candidemia in the cohort. Following intervention, administration of appropriate antifungal therapy improved by 40.4% (28.8% pre vs. 69.2% post, P < 0.01). Average time to effective treatment initiation following culture positivity decreased from 57.6 hours to 12 hours in the post-intervention group (P < 0.01). Thirty-day all-cause mortality was similar between the two groups (34.6% 38.4%, P = 0.84). Conclusion Implementation of a comprehensive candidemia care bundle by the ASP significantly improved the use and timing of initiation of appropriate antifungal therapy.

Abstract Background Empiric antibiotics for community acquired bacterial pneumonia (CABP) are often prescribed to patients with COVID-19, despite a low reported incidence of co-infections. Stewardship interventions targeted at facilitating appropriate antibiotic prescribing for CABP among COVID-19 patients are needed. We developed a guideline for antibiotic initiation and discontinuation for CABP in COVID-19 patients. The purpose of this study was to assess the impact of this intervention on the duration of empiric CABP antibiotic therapy among patients with COVID-19. Methods This was a single-center, retrospective, quasi-experimental study of adult patients admitted between 3/1/2020 to 4/25/2020 with COVID-19 pneumonia, who were initiated on empiric CABP antibiotics. Patients were excluded if they were initiated on antibiotics > 48 h following admission or if another source of infection was identified. The primary outcome was the duration of antibiotic therapy (DOT) prior to the guideline (March 1 to March27, 2020) and after guideline implementation (March 28 to April 25, 2020). We also evaluated the clinical outcomes (mortality, readmissions, length of stay) among those initiated on empiric CABP antibiotics. Results A total of 506 patients with COVID-19 were evaluated, 102 pre-intervention and 404 post-intervention. Prior to the intervention, 74.5% (n = 76) of patients with COVID-19 received empiric antibiotics compared to only 42% of patients post-intervention (n = 170), p < 0.001. The median DOT in the post-intervention group was 1.3 days shorter (p < 0.001) than the pre-intervention group, and antibiotics directed at atypical bacteria DOT was reduced by 2.8 days (p < 0.001). More patients in the post-intervention group were initiated on antibiotics based on criteria consistent with our guideline (68% versus 87%, p = 0.001). There were no differences between groups in terms of clinical outcomes. Conclusion Following the implementation of a guideline outlining recommendations for initiating and discontinuing antibiotics for CABP among COVID-19 inpatients, we observed a reduction in antibiotic prescribing and DOT. The guideline also resulted in a significant increase in the rate of guideline-congruent empiric antibiotic initiation.

Abstract Background Strategies to ensure optimal use of multiplex polymerase chain reaction (mPCR) testing results for antimicrobial stewardship in acute respiratory infections remain to be elucidated. This study sought to assess the impact of pharmacist intervention (by means of prospective feedback to prescribers) on overall antibiotic exposure in patients with viral-positive mPCR Respiratory Viral Panel (RVP) laboratory test results. Methods This retrospective cohort study included patients ≥18 years of age admitted to an acute care hospital with a viral-positive nasopharyngeal FilmArray Respiratory Panel test result receiving antibiotics for a suspected respiratory tract infection. Immunocompromised patients, patients with RVP samples from bronchiolar lavage, patients in the intensive care unit when samples were obtained, and patients receiving antibiotics for non-respiratory infections were excluded. Antibiotic exposure days, antibiotic discontinuation at 72 hours, and culture-positive bacterial superinfection were compared in two cohorts of patients, before and after the rollout of an educational pharmacist RVP stewardship initiative. Results Median antibiotic exposure days did not differ between the pre- and post-intervention groups (6 days vs. 7 days, P = 0.20). Antibiotic discontinuation at 72 hours was significantly lower in the post-intervention group (38% vs. 25%, P = 0.02). More patients in the post-intervention group had positive bacterial respiratory cultures (2.7% vs. 10%, P = 0.007) and chest radiographs suggestive of pneumonia (34.7% vs. 46%, P = 0.05). Patients with peak serum procalcitonin levels &lt;0.25 ng/mL were more likely to have antibiotics discontinued at 72 hours than those with peak levels ≥0.25 ng/mL (36% vs. 0%, P = 0.02). Conclusion An antimicrobial stewardship initiative by pharmacists among patients with viral-positive RVP results did not appear to impact antibiotic exposure days. Serum procalcitonin levels appeared to influence antibiotic discontinuation decisions. Alternative strategies for maximizing the antimicrobial stewardship impact of RVP testing should be explored.

Abstract Background C. difficile infection (CDI) is a common healthcare-associated infection and quality measure for hospitals. Diagnosis of CDI is challenging as testing modalities, i.e., nucleic acid amplification test (NAAT), are highly sensitive but cannot differentiate between colonization and infection. Therefore, judicious use of testing is critical to avoid unnecessary diagnosis and treatments. Methods This single-center, retrospective chart review evaluated the impact of a two-step diagnostic stewardship intervention on C. difficile diagnosis and use of oral vancomycin in the inpatient setting. For the first step of the intervention, providers were educated on appropriate diagnosis and treatment, and given access to an optional electronic CDI clinical decision support system (CDSS). For the second step of the intervention, the CDI NAAT stand-alone testing option was removed from the lab ordering menu and providers were required to use the CDSS to order testing. Clinical data including bed-days of care (BDOC), total number tests ordered, number of positive tests and use of oral vancomycin was collected for the pre-intervention period (1/1/16 – 3/31/17), post intervention period 1 (April 1, 2017–October 31/18) and post-intervention period 2 (November 1, 2018–March 31, 2019). Results Compared with the pre-intervention group, there were no significant differences in the number of total CDI NAATs ordered, positive CDI NAATs or vancomycin DOT/10,000 BDOC in post-intervention group 1. There was a reduction in the number of total CDI NAATs ordered (341 vs. 42 [87.7%]) and the number of positive CDI NAATs (56 vs. 7 [87.5%]) in post-intervention group 2, respectively. When this data were normalized based on bed days of care (BDOC), there were still significant reductions in NAATs ordered and number of positive CDI NAATs (64 vs. 27 [57.8%]; 11 vs. 5, respectively, [54.5%]) and with vancomycin oral DOT/10,000 BDOC (72 vs. 7 [90.3%]) (Table 1). Conclusion Provider education and an optional CDSS did not significantly impact CDI NAAT ordering or use of oral vancomycin for CDI. However, implementation of a mandatory CDSS for CDI testing was shown to significantly decrease the number of tests ordered, the number of positive tests, and the use of oral vancomycin.
