AbstractObjective:To evaluate the impact of methicillin resistance in Staphylococcus aureus on mortality, length of hospitalization, and hospital charges.Design:A cohort study of patients admitted to the hospital between July 1, 1997, and June 1, 2000, who had clinically significant S. aureus bloodstream infections.Setting:A 630-bed, urban, tertiary-care teaching hospital in Boston, Massachusetts.Patients:Three hundred forty-eight patients with S. aureus bacteremia were studied; 96 patients had methicillin-resistant S. aureus (MRSA). Patients with methicillin-susceptible S. aureus (MSSA) and MRSA were similar regarding gender, percentage of nosocomial acquisition, length of hospitalization, ICU admission, and surgery before S. aureus bacteremia. They differed regarding age, comorbidities, and illness severity score.Results:Similar numbers of MRSA and MSSA patients died (22.9% vs 19.8%; P = .53). Both the median length of hospitalization after S. aureus bacteremia for patients who survived and the median hospital charges after S. aureus bacteremia were significantly increased in MRSA patients (7 vs 9 days, P = .045; $19,212 vs $26,424, P = .008). After multivariable analysis, compared with MSSA bacteremia, MRSA bacteremia remained associated with increased length of hospitalization (1.29 fold; P = .016) and hospital charges (1.36 fold; P = .017). MRSA bacteremia had a median attributable length of stay of 2 days and a median attributable hospital charge of $6,916.Conclusion:Methicillin resistance in S. aureus bacteremia is associated with significant increases in length of hospitalization and hospital charges.

AbstractObjectives:To describe a longitudinal profile of resistance to beta-lactam antimicrobials among isolates of Staphylococcus aureus at a large university teaching hospital and to evaluate the impact of the methicillin resistance phenotype on resistance trends for non-beta-lactam antimicrobials.Design:Retrospective evaluation of antimicrobial susceptibility data for all 17,287 S. aureus isolates obtained from January 1986 through December 2000.Setting:The University of Chicago Hospitals, a family of tertiary-care, university-affiliated hospitals in Chicago, Illinois, consisting of 547 adult and pediatric beds.Results:The annual rate of resistance to methicillin increased from 13% in 1986 to 28% in 2000 (P < .001) and has not plateaued. For each non-beta-lactam antimicrobial tested, the annual rates of resistance were far higher among methicillinresistant S. aureus (MRSA) isolates than among methicillin-susceptible S. aureus (MSSA) isolates. The annual rates of resistance to the macrolide, lincosamide, and streptogramin (MLS) antimicrobials erythromycin and clindamycin increased among MSSA isolates (P < .01), but remained lower than 20%. Resistance to the MLS antimicrobials was higher among MRSA isolates (higher than 60%), but the annual rate decreased significantly during the study (P < .01).Conclusion:The prevalence of methicillin resistance among S. aureus isolates has continued to increase; resistance to non-beta-lactam antimicrobials is far more common among MRSA isolates. Recent decreases in the proportion of MRSA isolates resistant to non-beta-lactam antimicrobials suggest important changes in the epidemiology of this pathogen.

ABSTRACT Methicillin-susceptible Staphylococcus aureus (MSSA) bloodstream infections (BSIs) often lead to severe complications despite the availability of effective antibiotics. It remains unclear whether elevated vancomycin MICs are associated with worse outcomes. We conducted a 2-year retrospective cohort study (n = 252) of patients with MSSA BSIs at a tertiary care hospital. We defined reduced vancomycin susceptibility (RVS) as a Microscan MIC of 2 mg/liter. All strains were genotyped (spa) and assessed for agr functionality. Multivariable logistic regression models were used to examine the impact of RVS phenotype and strain genotype on 30-day all-cause mortality and complicated bacteremia (metastatic spread, endovascular infection, or duration ≥3 days). One-third of patients (84/252) were infected with RVS isolates. RVS Infections were more frequently associated with metastatic or embolic sites of infection (36% versus 17%, P < 0.001), and endovascular infection (26% versus 12%, P = 0.004). These infections occurred more often in patients with fewer underlying comorbidities (Charlson comorbidity index of ≥3 [73% versus 88%, P = 0.002]). Genotyping identified 127 spa-types and 14 Spa-clonal complexes (Spa-CCs). Spa-CC002 and Spa-CC008 were more likely to exhibit the RVS phenotype versus other Spa-CCs (OR = 2.2, P < 0.01). The RVS phenotype was not significantly associated with 30-day mortality; however, it was associated with complicated bacteremia (adjusted odds ratio of 2.35 [range, 1.26 to 4.37]; P = 0.007) in adjusted analyses. The association of RVS strains with complicated infection and fewer underlying comorbidities suggests the phenotype as a potential marker of strain virulence in MSSA BSIs. The RVS phenotype itself was not a significant predictor of mortality in this patient cohort. Further studies are necessary to explore this host-pathogen relationship.

Length Of Hospitalization

Background and Purpose: The duration of hospitalization and associated factors are not well studied in national cohorts. We identified the proportion and determinants of prolonged hospitalization and determined the impact on hospital charges using nationally representative data. Methods: National estimates of length of stay, mortality, and hospital charges incurred in patients admitted with primary diagnosis of ischemic stroke (ICD-9 CM diagnosis-related code 433.01, 433.11, 433.21, 433.31, 433.81, 433.91, 434.01, 434.11, 434.91, and 436) using Nationwide Inpatient Sample data from 2010 to 2015. Nationwide Inpatient Sample is the largest all-payer inpatient care database in the United States. Patient who were transferred from another acute hospital or had mortality within 2 days of admission were excluded from the analysis. All the variables pertaining to hospitalization were compared in four quartiles based on distribution data for length of hospital stay (≤2, 3 to 4, 5 to 6 and ≥7 days). Results: A total of 2,490,136 patients were admitted with the diagnosis of ischemic attack during the study period. The median length of stay for hospitalization was 4 days. The length of hospitalization was ≤2, 3 to 4, 5 to 6 and ≥7 days in 706,550 (28.4%), 842,872 (33.8%), 417,592 (16.8%) and 523,122 (21.0%) patients, respectively. The mean hospitalization charges were $22,819, $32,593, $ 45,486 and $97,868 for patients hospitalized in four quartiles, respectively. In the multivariate analysis, the following patient factors and in hospital complications were associated with above median length of hospitalization of ≥4 days: age >65 years (odds ratio [OR], 1.06), women (OR, 1.07), history of alcohol use (OR, 1.29), deep venous thrombosis (OR, 2.67), urinary tract infection (OR, 1.68), pneumonia (OR, 1.53), sepsis (OR, 1.85), pulmonary embolism (OR, 1.48), admission to urban teaching hospitals (OR, 1.07), Medicaid insurance (OR, 1.53), and hospital location in Northeast US region (OR, 1.86; all P values <0.0001). Conclusions: The hospital stay in more than half of patients admitted with ischemic stroke is 4 days or greater. Strategies that focus on modifiable factors associated with prolonged hospital stay may reduce the hospitalization charges in United States.

Background: Discontinuation of contact precautions for methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococci (VRE) have failed to show an increase in associated transmission or infections in adult healthcare settings. Pediatric experience is limited. Objective: We evaluated the impact of discontinuing contact precautions for MRSA, VRE, and extended-spectrum β-lactamase–producing gram-negative bacilli (ESBLs) on device-associated healthcare-associated infections (HAIs). Methods: In October 2018, contact precautions were discontinued for children with MRSA, VRE, and ESBLs in a large, tertiary-care pediatric healthcare system comprising 2 hospitals and 620 beds. Coincident interventions that potentially reduced HAIs included blood culture diagnostic stewardship (June 2018), a hand hygiene education initiative (July 2018), a handshake antibiotic stewardship program (December 2018) and multidisciplinary infection prevention rounding in the intensive care units (November 2018). Compliance with hand hygiene and HAI prevention bundles were monitored. Device-associated HAIs were identified using standard definitions. Annotated run charts were used to track the impact of interventions on changes in device-associated HAIs over time. Results: Average hand hygiene compliance was 91%. Compliance with HAI prevention bundles was 81% for ventilator-associated pneumonias, 90% for catheter-associated urinary tract infections, and 97% for central-line–associated bloodstream infections. Overall, device-associated HAIs decreased from 6.04 per 10,000 patient days to 3.25 per 10,000 patient days after October 2018 (Fig. 1). Prior to October 2018, MRSA, VRE and ESBLs accounted for 10% of device-associated HAIs. This rate decreased to 5% after October 2018. The decrease in HAIs was likely related to interventions such as infection prevention rounds and handshake stewardship. Conclusions: Discontinuation of contact precautions for children with MRSA, VRE, and ESBLs were not associated with increased device-associated HAIs, and such discontinuation is likely safe in the setting of robust infection prevention and antibiotic stewardship programs.Funding: NoneDisclosures: None

Abstract Background Coronavirus disease 19 (COVID-19) leading to acute respiratory distress syndrome is associated with need for intensive care (IC), mechanical ventilation (MV), and prolonged recovery. These patients are thus predisposed to blood stream infections which can worsen outcomes. This risk may be aggravated by adjunctive therapies. Methods We reviewed the medical records of all adults admitted to Stony Brook University Hospital, NY, from March 1 to April 15, 2020 with severe COVID-19 pneumonia (requiring high-flow O2). Patients who received MV or died within 24h were excluded. Patients were followed until death or hospital discharge. We reviewed positive blood cultures (PBC) for pathogenic microorganisms, and calculated the incidence of bacteremia, rates of infective endocarditis (IE), and impact on mortality. Microbes isolated only once and belonging to groups defined as commensal skin microbiota were labelled as contaminants. We also examined the impact of adjunctive therapies with immunosuppressive potential (steroids and tocilizumab), on bacteremia. Results A total of 469 patients with severe COVID-19 pneumonia were included (Table 1). Of these, 199 (42.4%) required IC and 172 (36.7%) MV. Median length of stay was 13 days (8–22) and 94 (20.0%) had PBC. Of these, 43 were considered true pathogens (bacteremia), with predominance of E. faecalis and S. epidermidis, and 51 were considered contaminants (Table 2). The incidence of bacteremia (43/469, 9.2%) was 5.1 per 1000 patient-days (95%CI 3.8–6.4). An echocardiogram was performed in 21 patients, 1 had an aortic valve vegetation (IE) by methicillin sensitive S. aureus. Bacteremia rates were nonsignificantly higher with steroids (5.9 vs 3.7 per 1000 patient-days; P=0.057). Use of tocilizumab was not associated with bacteremia (5.8 vs 4.8 per 1000 patient-days; P=0.28). Mortality was nonsignificantly higher in patients with (15/43, 34.9%) vs. without (108/426, 25.4%) bacteremia (P=0.20). Length of stay was the strongest predictor of bacteremia, with risk increasing by 7% (95%CI 6%-9%, P&lt; 0.001) per additional day. Cohort Characteristics of Patients with Severe COVID-19 Pneumonia on High-Flow O2 (N= 469) All Microorganisms Isolated from Blood Cultures Conclusion The incidence of bacteremia was relatively low and IE was uncommon in this study of severe COVID-19 patients. Risk of bacteremia increased with longer hospital stay and with steroids use, but not with tocilizumab. Disclosures All Authors: No reported disclosures

Objective: To evaluate the impact of antimicrobial stewardship (AMS) on antibiotic prescribing patterns and certain clinical outcomes, the length of stay (LOS) and the re-admission rate (RR) of the patients treated within the medical ward of a tertiary care hospital in Malaysia. Methods: This quasi-experimental study was conducted retrospectively. The prescriptions of the AMS included alert antibiotics (AA) such as cefepime, ceftazidime, colistin (polymyxin E), imipenem-cilastatin, meropenem, piperacillin-tazobactam and vancomycin were reviewed for the period of 24 mo before (May, 2012–April, 2014) and after (May, 2014–April, 2016) the AMS implementation for the patients who were treated within the medical ward of a Malaysian tertiary care hospital. Patterns of antibiotics prescribed were determined descriptively. The impact of the AMS on the length of stay (LOS) and readmission rate (RR) was determined by the interrupted time series (ITS) comparative analysis of the pre-and post-AMS segments segregated by the point of onset (May, 2014) of the AMS program. Data analysis was performed through autoregressive integrated moving average (ARIMA) Winter Additive model and the Games-Howell non-parametric post hoc test by using IBM Statistical Package for Social Sciences version 25.0 for Windows (SPSS Inc., Chicago, IL, USA). Results: A total of 1716 prescriptions of the AA included for the AMS program showed that cefepime (623, 36.3%) and piperacillin-tazobactam (424, 24.7%) were the most prescribed antibiotics from May 2012 to April 2016. A 23.6% drop in the number of the AA prescriptions was observed during the 24-month post-AMS period. The LOS of the patients using any of the AA showed a post-AMS decline by 3.5 d. The patients’ LOS showed an average reduction of 0.12 (95% CI, 0.05–0.19, P=0.001) with the level and slope change of 0.18 (95% CI, 0.04–0.32, P=0.02) and 0.074 (95% CI, 0.02–0.12, P=0.002), respectively. Similarly, the percent RR reduced from 20.0 to 9.85 during the 24-month post-AMS period. The observed post-AMS mean monthly reduction of the RR for the patients using any AA was 0.38 (95% CI, 0.23–0.53, P<0.001) with the level and slope change of 0.33 (95% CI, 0.14–0.51, P=0.02) and 0.37 (95% CI, 0.16–0.58, P=0.001), respectively. Conclusion: The AMS program of a Malaysian tertiary care hospital was a coordinated set of interventions implemented by the AMS team of the hospital that comprised of the infectious diseases (ID) physician, clinical pharmacists and microbiologist. The successful implementation of the AMS program from May, 2014 to April, 2016 within the medical ward resulted in the drop of the number of AA prescriptions that sequentially resulted in the significant (P<0.05) post-AMS reduction of the LOS and the RR.

Introduction: Methicillin-Resistant Staphylococcus aureus(MRSA) infection is a major global healthcare problem, the prevalence of which varies from 25-50% in India. It is known to cause Skin and Soft tissue Infections (SSI), endovascular infections, endocarditis, pneumonia, septic arthritis, osteomyelitis, and sepsis. Vancomycin is the drug of choice for treating severe MRSA infections. Ceftaroline, a fifth-generation cephalosporin has been approved by the United States Food and Drug Administration (US FDA) for treating acute bacterial SSI caused by susceptible micro-organisms including MRSA, Community acquired respiratory tract infection, MRSA bacteremia and endocarditis. Aim: To assess the susceptibility of clinical isolates of S. aureusto ceftaroline, in a Tertiary Care Hospital. Materials and Methods: This prospective study was conducted in the Department of Microbiology of a Tertiary Care Hospital over a period of two months from June 2019 to July 2019. S.aureus isolates from various clinical samples were screened for methicillin resistance by disc diffusion method using cefoxitin disc and ceftaroline susceptibility of these isolates was assessed by E-strip method. The isolates were classified as ceftaroline susceptible, Susceptibility Dose Dependent (SDD) and ceftaroline resistant respectively as per CLSI guidelines. A descriptive analysis of the data was done and the results were presented as frequencies and percentages. Results: All the S.aureus isolates were found to be susceptible to ceftaroline. Methicillin Sensitive Staphylococcus aureus(MSSA) isolates had lower Minimum Inhibitory Concentration (MIC) when compared to MRSA. The highest MIC among MRSA was 0.5 μg/mL. Conclusion: Ceftaroline can be considered as an effective alternative for treatment of infections caused by MRSA.

Introduction: We assessed outcomes and costs of open prostatectomy (OP) versus robotic-assisted prostatectomy (RAP) at a single tertiary care university hospital.Methods: We retrospectively analyzed 200 consecutive OP by 1 experienced open surgeon (MG) and 200 consecutive RAP by an experienced open surgeon (SLG), after allowing for a short learning curve of 70 cases.Results: The 2 groups had similar demographics, including mean age (64.7 vs. 64.2) and mean body mass index (27.2 vs. 27.2). The OP group had a higher proportion of higher risk cancers compared to the RAP group (32.5% vs. 8.5%). Mean skin-to-skin operative room time was less for the OP (114.2 vs. 234.1 minutes). Transfusion rates were similar at 1.5% with OP compared to 3.5% with RAP. The mean length of stay was 1.78 days for OP compared to 1.76 days for RAP, for the last 100 patients in each group. The OP group had more high-grade disease in the prostatectomy specimen, with Gleason ≥8 in 23.5% compared to 3.5% in the RAP group. Positive surgical margin rates were comparable at 31% for OP and 24.6% for RAP, and remained similar after stratification for pT2 and pT3 disease. The grade I and II perioperative complication rate (Clavien-Dindo classification) was lower in the OP group (8.5% vs. 20%). Postoperative stress urinary incontinence rates (4.8% for OP and 4.6% for RAP) and biochemical-free status (91.8% for OP and 96% for RAP) did not differ at 12 months post-surgery. The additional cost of RAP was calculated as $5629 per case. The main limitations of this study are its retrospective nature and lack of validated questionnaires for evaluation of postoperative functional outcomes.Conclusion: While hospital length of stay, transfusion rates, positive surgical margin rates and postoperative urinary incontinence were similar, OP had a shorter operative time and a lower cost compared to the very early experience of RAP. Future parallel prospective analysis will address the impact of the learning curve on these outcomes.
