Abstract
BACKGROUND Reducing rehospitalization has been a primary focus of hospitals and payors. Recurrence of Clostridioides difficile infection (CDI) is common and often results in rehospitalization. Factors that influence rehospitalization for CDI are not well understood. OBJECTIVE To determine the risk factors that influence rehospitalization caused by CDI. DESIGN A retrospective cohort study from January 1, 2018, to December 31, 2018, of patients aged ≥18 who tested positive for C. difficile while hospitalized. SETTING Academic hospital. METHODS The risk of rehospitalization was assessed across exposures during and after the index hospitalization using a Cox proportional hazards model. The primary outcome of this study was 60-day CDI-related rehospitalization. RESULTS There were 559 hospitalized patients with a positive CD test during the study period, and 408 patients were included for analysis. All-cause rehospitalization was 46.1% within 60 days of the index hospital discharge. Within 60 days of discharge, 68 patients developed CDI, of which 72.5% (49 of 68) were rehospitalized specifically for the management of CDI. The risk of rehospitalization in patients with CDI was higher among patients who were exposed to systemic antibiotics ([adjusted hazard ratio] aHR: 2.78; 95% CI, 1.36-5.64) and lower among patients who had post-discharge follow-up addressing C. difficile (aHR: 0.53; 95% CI, 0.28-0.98). CONCLUSIONS Exposure to systemic antibiotics increased the risk of rehospitalization due to CDI, while post-discharge follow-up decreased the risk of rehospitalization due to CDI. Comprehensive transitions of care for hospitalized patients with C. difficile may reduce the risk of CDI-related rehospitalization.

Abstract
The evaluation and workup of fever and the use of antibiotics to treat infections is part of daily practice in the surgical intensive care unit (ICU). Fever can be infectious or non-infectious; it is important to distinguish between the two entities wherever possible. The evidence is growing for shortening the duration of antibiotic treatment of common infections. The purpose of this clinical consensus document, created by the American Association for the Surgery of Trauma Critical Care Committee, is to synthesize the available evidence, and to provide practical recommendations. We discuss the evaluation of fever, the indications to obtain cultures including urine, blood, and respiratory specimens for diagnosis of infections, the use of procalcitonin, and the decision to initiate empiric antibiotics. We then describe the treatment of common infections, specifically ventilator-associated pneumonia, catheter-associated urinary infection, catheter-related bloodstream infection, bacteremia, surgical site infection, intra-abdominal infection, ventriculitis, and necrotizing soft tissue infection.

Evaluation of methicillin-resistant Staphylococcus aureus (MRSA) bacteremia: Epidemiology, clinical characteristics, and outcomes in the older patients in a tertiary teaching hospital in Malaysia. BMC Infect Dis 2023; 23:241. [PMID: 37072768 PMCID: PMC10111773 DOI: 10.1186/s12879-023-08206-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2022] [Accepted: 03/30/2023] [Indexed: 04/20/2023] Open
Abstract
BACKGROUND Methicillin-resistant Staphylococcus aureus (MRSA) bacteremia is a major concern in the global healthcare system. However, data from Asian regions dealing with the singularity of this infection in older persons is lacking. We aimed to identify the differences in the clinical characteristics and outcomes of MRSA bacteremia between adults aged 18-64 and ≥ 65 years. METHODS A retrospective study cohort was conducted at the University Malaya Medical Centre (UMMC) on cases of MRSA bacteremia from 2012 to 2016. Patient demographic and clinical data were collected for risk factors analyses. RESULTS New cases of MRSA bacteremia showed a trend of increase from 0.12 to 100 admissions in 2012 to 0.17 per 100 admissions in 2016 but a drop was observed in 2014 (0.07 per 100 admissions). Out of the 275 patients with MRSA bacteremia, 139 (50.5%) patients were aged ≥ 65 years old. Co-morbidities and severity at presentation were significantly higher among older adults, including diabetes mellitus (p = 0.035), hypertension (p = 0.001), and ischemic heart disease (p < 0.001), as well as higher Charlson Comorbidity Index (p < 0.001) and Pitt bacteremia scores (p = 0.016). Central line-associated bloodstream infections were more common among younger patients (37.5% vs. 17.3% in older patients, p < 0.001), while skin and soft tissue infections are more frequent among older adults (20.9% vs. 10.3% in younger patients, p = 0.016). All-cause mortality and in-hospital mortality were significantly higher in older patients (82.7% and 56.1% vs. 63.2% and 28.7% in younger patients, p < 0.001). Multivariate analysis revealed age ≥ 65 years (adjusted odds ratio: 3.36; 95% confidence interval: 1.24-9.13), Pitt score ≥ 3 (2.15; 1.54-3.01), hospital (6.12; 1.81-20.72) and healthcare (3.19; 1.30-7.81) acquisition of MRSA, indwelling urinary catheters (5.43; 1.39-21.23), inappropriate targeted treatment (8.08; 1.15-56.86), lack of infectious disease team consultation (2.90; 1.04-8.11) and hypoalbuminemia (3.31; 1.25-8.79), were significant risk factors for 30-day mortality. CONCLUSION Older patients' risk of mortality from MRSA bacteremia was three times higher than younger patients. Our data will contribute to developing and validating a robust scoring system for risk-stratifying patients to achieve better management and improved clinical outcomes.

Abstract
Methicillin-resistant Staphylococcus aureus (MRSA) is a devastating pathogen responsible for a variety of life-threatening infections. A distinctive characteristic of this pathogen is its ability to persist in the bloodstream for several days despite seemingly appropriate antibiotics. Persistent MRSA bacteremia is common and is associated with poor clinical outcomes. The etiology of persistent MRSA bacteremia is a result of the complex interplay between the host, the pathogen, and the antibiotic used to treat the infection. In this review, we explore the factors related to each component of the host-pathogen interaction and discuss the clinical relevance of each element. Next, we discuss the treatment options and diagnostic approaches for the management of persistent MRSA bacteremia.

Abstract
INTRODUCTION Vancomycin is commonly used during outpatient parenteral antimicrobial therapy (OPAT). Therapeutic drug monitoring (TDM) of vancomycin is recommended to ensure effective and safe therapy, as use has been associated with acute kidney injury (AKI). METHODS The MarketScan® Commercial Database was queried from 2010 to 2016 to identify patients aged 18-64 years discharged from an inpatient hospitalization on vancomycin OPAT. The primary endpoint was hospital readmission with AKI within 6 weeks of index hospital discharge. TDM was defined as at least one vancomycin level obtained during outpatient therapy. Bivariate analysis was used to examine associations with outcomes; significant factors were incorporated into a multivariable logistic regression model. RESULTS A total of 14,196 patients were included in the study; median age was 54 years and 53.8% were male. Readmission with AKI occurred in 385 (2.7%) and was independently associated with chronic kidney disease (aOR 2.63 [95%CI 1.96-3.52]), congestive heart failure (1.81 [1.34-2.44]), chronic liver disease (1.74 [1.17-2.59]), hypertension (1.73 [1.39-2.17]), septicemia (1.61 [1.30-2.00]), and concomitant OPAT with IV penicillins (1.73 [1.21-2.49]) while skin and soft tissue infection (0.67 [0.54-0.83]) and surgical site infection (0.74 [0.59-0.93]) were associated with lower risk of readmission with AKI. TDM was not associated with lower risk of readmission with AKI. CONCLUSION Chronic kidney disease, congestive heart failure, hypertension, chronic liver disease, septicemia, and concomitant OPAT with IV penicillins were significantly associated with higher risk of readmission with AKI during vancomycin OPAT.

Abstract
OBJECTIVES To evaluate the antibacterial activity of plumbagin (PGN) against multidrug resistance (MDR) clinical isolates. METHODS This study was carried out at the Department of Clinical Lab Sciences, King Khalid University from October 6, 2021 to December 14, 2021. We investigated the antibacterial and anti-virulence activity of PGN against MDR Gram-negative (Escherichia coli, Klebsiella pneumoniae, Salmonella Typhi, and Pseudomonas aeruginosa) and Gram-positive (Staphylococcus aureus [S. aureus], Staphylococcus saprophyticus [S. saprophyticus], Streptococcus pyogenes, and Enterococcus faecalis) clinical bacterial isolates. Agar well diffusion, microdilution assay, colony count method, biofilm formation, and time-kill kinetics were employed to probe the MIC, MBC, and anti-virulence activity of PGN. RESULTS Plumbagin inhibited the growth of all tested isolates, with S. saprophyticus exhibiting the highest sensitivity. MIC values ranged from 0.029 to 0.117 µg/mL whereas MBC ranged from 0.235 to 0.94 µg/mL, with 79% to 99% growth inhibition. Moreover, all tested isolates showed a marked decrease in biofilm formation, with S. saprophyticus and S. aureus being the most sensitive. CONCLUSION Plumbagin is a stand-alone, broad spectrum antibacterial with promising potential against the rising threat of antimicrobial resistance.

Abstract
IMPORTANCE Staphylococcus aureus bacteremia is associated with a significant burden of mortality, morbidity, and health care costs. Infectious disease consultation may be associated with reduced mortality and bacteremia recurrence rates. OBJECTIVE To evaluate the cost-effectiveness of infectious disease consultation for Staphylococcus aureus bacteremia. DESIGN, SETTING, AND PARTICIPANTS In this economic evaluation, a decision-analytic model was constructed comparing infectious disease consult with no consult. The population was adult hospital inpatients with Staphylococcus aureus bacteremia diagnosed with at least 1 positive blood culture. Cost-effectiveness was calculated as deaths averted and incremental cost-effectiveness ratios. Uncertainty was addressed by plotting cost-effectiveness planes and acceptability curves for various willingness-to-pay thresholds. Costs and outcomes were calculated for a time horizon of 6 months. The analysis was performed from a societal perspective and included studies that had been published by January 2022. INTERVENTIONS Patients received or did not receive formal bedside consultation after positive blood cultures for Staphylococcus aureus bacteremia. MAIN OUTCOMES AND MEASURES The main outcomes were incremental difference in effectiveness (survival probabilities), incremental difference in cost (US dollars) and incremental cost-effectiveness ratios (US dollars/deaths averted). RESULTS This model included 1708 patients who received consultation and 1273 patients who did not. In the base-case analysis, the cost associated with the infectious disease consult strategy was $54 137.4 and the associated probability of survival was 0.77. For the no consult strategy, the cost was $57 051.2, and the probability of survival was 0.72. The incremental difference in cost between strategies was $2913.8, and the incremental difference in effectiveness was 0.05. Overall, consultation was associated with estimated savings of $55 613.4/death averted (incremental cost-effectiveness ratio, -$55613.4/death averted). In the probabilistic analysis, at a willingness-to-pay threshold of $50 000, infectious disease consult was cost-effective compared with no consult in 54% of 10 000 simulations. In cost-effectiveness acceptability curves, the consult strategy was cost-effective in 58% to 73%) of simulations compared with no consult for a willingness-to-pay threshold ranging from $0 to $150 000. CONCLUSIONS AND RELEVANCE These findings suggest that infectious disease consultation may be a cost-effective strategy for management of Staphylococcus aureus bacteremia and that it is associated with health care cost-savings.

Abstract
Background:Staphylococcus aureus bloodstream infection (SA-BSI) causes morbidity and mortality. We established a management protocol for patients with SA-BSI aimed at improving quality of care and patient outcomes. Methods: A retrospective pre−post intervention study was conducted at Maharaj Nakorn Chiang Mai Hospital from 1 October 2019 to 30 September 2020 in the pre-intervention period and from 1 November 2020 to 31 October 2021 in the post-intervention period. Results: Of the 169 patients enrolled, 88 were in the pre-intervention and 81 were in the post-intervention periods. There were similar demographic characteristics between the two periods. In the post-intervention period, evaluations for metastatic infections were performed more frequently, e.g., echocardiography (70.5% vs. 91.4%, p = 0.001). The appropriateness of antibiotic prescription was higher in the post-intervention period (42% vs. 81.5%, p < 0.001). The factors associated with the appropriateness of antibiotic prescription were ID consultation (OR 15.5; 95% CI = 5.9−40.8, p < 0.001), being in the post-intervention period (OR 9.4; 95% CI: 3.5−25.1, p < 0.001), and thorough investigations for metastatic infection foci (OR 7.2; 95% CI 2.1−25.2, p = 0.002). However, the 90-day mortality was not different (34.1% and 27.2% in the pre- and post-intervention periods, respectively). The factors associated with mortality from the multivariate analysis were the presence of alteration of consciousness (OR 11.24; 95% CI: 3.96−31.92, p < 0.001), having a malignancy (OR 6.64; 95% CI: 1.83−24.00, p = 0.004), hypoalbuminemia (OR 5.23; 95% CI: 1.71−16.02, p = 0.004), and having a respiratory tract infection (OR 5.07; 95% CI: 1.53−16.84, p = 0.008). Source control was the only factor that reduced the risk of death (OR 0.08; 95% CI: 0.01−0.53, p = 0.009). Conclusion: One-third of patients died. Hospital-wide protocol implementation significantly improved the quality of care. However, the mortality rate did not decrease.

Abstract
Introduction Staphylococcus aureus bacteremia (SAB) in children is associated with significant mortality and morbidity, including recurrent bacteremia. Infectious disease consultation (IDC) improves SAB outcomes in adult patients. However, increasing IDC and impact for pediatric patients with SAB is not well described. Methods This quality improvement project aimed to increase IDC for SAB events at a quaternary pediatric medical center. First, we evaluated the local practices regarding pediatric SAB and engaged stakeholders (July 2018-August 2020). We added an advisory comment supporting IDC for SAB to all blood culture results in September 2020. Using statistical process control charts, we monitored the number of SAB events with IDC before a SAB event without IDC. Finally, we evaluated SAB recurrences before and after initiating the advisory comment. Results In the baseline period, 30 of 49 (61%) SAB events received an IDC with a mean of 1.4 SAB events with IDC before a SAB event without IDC. Postintervention, 22 of 23 (96%) SAB events received IDC with a mean of 14 events with IDC before 1 event without IDC. The SAB recurrence rate was 8%, with 6 events in 4 children; none of the index cases resulting in recurrence received an IDC (P = 0.0002), and all occurred before any intervention. Conclusions An electronic advisory comment supporting IDC for SAB significantly increased the rate of pediatric IDC with no further SAB recurrence episodes following intervention. This low-resource intervention may be considered in other pediatric centers to optimize SAB management.

Abstract
Abstract
Background
Enterococcal bacteremia carries significant mortality. While multiple studies have evaluated the impact of infectious disease consultation (IDC) on this condition, these studies were limited by the low numbers of patients enrolled. This systemic literature review and meta-analysis were conducted to determine whether IDC was associated with a mortality benefit among patients with enterococcal bacteremia.
Methods
We performed a systematic literature search using 5 databases for studies evaluating IDC among patients with enterococcal bacteremia. We conducted a meta-analysis to assess whether IDC was associated with reduced mortality. Random-effect models were used to calculated pooled odds ratios (pORs). Heterogeneity was evaluated using I2 estimation and the Cochrane Q statistic test.
Results
The systemic literature review revealed 6496 reports, from which 18 studies were evaluated in the systemic literature review and 16 studies in the meta-analysis. When all studies were pooled, the association between IDC and mortality was not statistically significant with a pOR of 0.81 (95% CI, 0.61-1.08) and there was substantial heterogeneity (I2=58%). When the studies were limited to those reporting multivariate analysis including IDC, there was a significant protective effect of IDC (pOR=0.40; 95% CI, 0.24-0.68) without heterogeneity (I2=0%). Some studies also showed additional benefits to IDC, including appropriate antibiotic therapy, and improved diagnostic use.
Conclusions
IDC was associated with 60% lower odds of mortality when patients were well-matched, potentially through improvement in the care for patients with enterococcal bacteremia. IDC should be considered a part of routine care for patients with enterococcal bacteremia.

Abstract
Background Commensal coagulase negative Staphylococcus lugdunensis may cause severe bacteremia (SLB) and complications. Treatment of SLB is not fully established and we wanted to evaluate if infectious diseases specialist consultation (IDSC) would improve management and prognosis. Methods Multicenter retrospective study of SLB patients followed for 1 year. Patients were stratified according to bedside (formal), telephone (informal) or lack of IDSC within 7 days of SLB diagnosis. Results Altogether, 104 SLB patients were identified: 24% received formal bedside and 52% informal telephone IDSC whereas 24% were managed without any IDSC. No differences in demographics, underlying conditions or severity of illness were observed between the groups. Patients with bedside IDSC, compared to telephone IDSC or lack of IDSC, had transthoracic echocardiography more often performed (odds ratio [OR] 4.00; 95% confidence interval [CI] 1.31–12.2; p = 0.012) and (OR 16.0; 95% CI, 4.00–63.9; P<0.001). Bedside IDSC was associated with more deep infections diagnosed compared to telephone IDSC (OR, 7.44; 95% CI, 2.58–21.4; p<0.001) or lack of IDSC (OR, 9.56; 95% CI, 2.43–37.7; p = 0.001). The overall mortality was 7%, 10% and 17% at 28 days, 90 days and 1 year, respectively. Considering all prognostic parameters, patients with IDSC, compared to lack of IDSC, had lower 90 days and 1 year mortality (OR, 0.11; 95% CI, 0.02–0.51; p = 0.005) and (OR, 0.22; 95% CI, 0.07–0.67; p = 0.007). Conclusion IDSC may improve management and outcome of Staphylococcus lugdunensis bacteremia.

Abstract
BACKGROUND Persistent Staphylococcus aureus bacteremia (SAB) is defined based on varying duration in literature. The primary objective was to determine the risk of poor outcomes in relation to bacteremia duration. METHODS Multicenter, prospective, observational study of adult hospitalized patients with SAB. Medical records were reviewed for pertinent data. Patients were grouped by bacteremia duration: short (1-2 days), intermediate (3-6 days), and prolonged (≥7 days) and compared for risk factors and outcomes. RESULTS Of 884 patients, 63% had short, 28% intermediate, and 9% prolonged bacteremia. Overall mean age was 57 years, and 70% were male. The prolonged group had the highest proportion of methicillin-resistant SAB (P < .0001). Choice of antibiotic therapy did not significantly affect bacteremia duration; however, time to source-control procedure was delayed in the prolonged and intermediate groups compared with the short group (3.5 vs 3 vs 1 day, P < .0001). Metastatic complications, length of stay, and 30-day mortality were progressively worse as bacteremia duration increased (P < .0001). Every continued day of bacteremia was associated with a relative risk of death of 1.16 (95% confidence interval, 1.10-1.22; P < .0001), with a significant increase in risk starting at 3 days as determined by receiver operating characteristic analysis. CONCLUSIONS Optimal management of SAB should target bacterial clearance as soon as possible to minimize incremental risk of mortality with each day of positive blood culture. Delay in source control but not type of antistaphylococcal therapy was significantly associated with prolonged bacteremia and worse outcomes.

Abstract
Background Sepsis is an important cause of morbidity and mortality in the pregnant patient. Injection drug use in pregnant populations has led to increased cases of bacteremia and infective endocarditis (IE) due to Staphylococcus aureus. We describe all cases of S. aureus bacteremia and IE among admitted pregnant patients at our hospital over a 6-year period. Methods This was a retrospective review of pregnant patients hospitalized with S. aureus bacteremia between April 2013 and November 2019. Maternal in-hospital mortality and fetal in-hospital mortality were the primary outcomes measured; the secondary outcome was the rate of 6-month maternal readmission. Results Twenty-seven patients were included; 15 (56%) had IE. The median (interquartile range [IQR]) age was 29 (25-33) years; 22 (82%) patients had methicillin-resistant S. aureus. Infection onset occurred at a median (IQR) of 29 (23-34) weeks' gestation. Twenty-three (85%) mothers reported active injection drug use, and 21 (78%) were hepatitis C seropositive. Fifteen (56%) mothers required intensive care unit (ICU) care. Twenty-two (81%) patients delivered 23 babies; of the remaining 5 mothers, 3 (11%) were lost to follow-up and 2 (7%) terminated pregnancy. Sixteen (73%) babies required neonatal ICU care, and 4/25 (16%) infants/fetuses died during hospitalization. One (4%) mother died during hospitalization, and 7/26 (27%) mothers were readmitted to the hospital within 6 months for infectious complications. Conclusions Injection drug use is a modifiable risk factor for S. aureus bacteremia in pregnancy. Fetal outcomes were poor, and mothers were frequently readmitted secondary to infection. Future targeted interventions are needed to curtail injection drug use in this population.

Abstract
IMPORTANCE Staphylococcus aureus bacteremia (SAB) is common and associated with poor long-term outcomes. Previous studies have demonstrated an association between infectious diseases (ID) consultation and improved short-term (ie, within 90 days) outcomes for patients with SAB, but associations with long-term outcomes are unknown. OBJECTIVE To investigate the association of ID consultation with long-term (ie, 5 years) postdischarge outcomes among patients with SAB. DESIGN, SETTING, AND PARTICIPANTS This cohort study included all patients (N = 31 002) with a first episode of SAB who were discharged alive from 116 acute care units of the nationwide Veterans Health Administration where ID consultation was offered. Data were collected from January 2003 to December 2014, with follow-up through September 30, 2018. Data analysis was conducted from February to December 2019. EXPOSURES Infectious diseases consultation during the index hospital stay. MAIN OUTCOMES AND MEASURES The primary outcome was time to development of a composite event of all-cause mortality or recurrence of SAB within 5 years of discharge. As secondary outcomes, SAB recurrence and all-cause mortality with and without recurrence were analyzed while accounting for semicompeting risks. RESULTS The cohort included 31 002 patients (30 265 [97.6%] men; median [interquartile range] age at SAB onset, 64.0 [57.0-75.0] years). Among 31 002 patients, there were 18 794 (60.6%) deaths, 4772 (15.4%) SAB recurrences, and 20 414 (65.8%) composite events during 5 years of follow-up; 12 773 deaths (68.0%) and 2268 recurrences (47.5%) occurred more than 90 days after discharge. Approximately half of patients (15 360 [49.5%]) received ID consultation during the index hospital stay; ID consultation was associated with prolonged improvement in the composite outcome (adjusted hazard ratio at 5 years, 0.71; 95% CI, 0.68-0.74; P < .001). Infectious diseases consultation was also associated with improved outcomes when all-cause mortality without recurrence and SAB recurrence were analyzed separately (all-cause mortality without recurrence: adjusted hazard ratio at 5 years, 0.77; 95% CI, 0.74-0.81; P < .001; SAB recurrence: adjusted hazard ratio at 5 years, 0.68; 95% CI, 0.64-0.72; P < .001). CONCLUSIONS AND RELEVANCE Having an ID consultation during the index hospital stay among patients with SAB was associated with improved postdischarge outcomes for at least 5 years, suggesting that contributions of ID specialists to management during acute infection may have a substantial influence on long-term outcomes. Further investigations of the association of ID consultation with outcomes after S aureus should include long-term follow-up.

Abstract
Background Formal infectious diseases specialist (IDS) consultation has been shown to improve short-term outcomes in Staphylococcus aureus bacteremia (SAB), but its effect on long-term outcomes lacks evaluation. Methods This retrospective study followed 367 methicillin-sensitive (MS) SAB patients for 10 years. The impact of formal IDS consultation on risk for new bacteremia and outcome during long-term follow-up was evaluated. Patients who died within 90 days were excluded to avoid interference from early deceased patients. Results Three hundred four (83%) patients had formal IDS consultation, whereas 63 (17%) received informal or no IDS consultation. Formal consultation, compared with informal or lack of consultation, was associated with a reduced risk of new bacteremia caused by any pathogen within 1 year (odds ratio [OR], 0.39; 95% confidence interval [CI], 0.18–0.84; P = .014; 8% vs 17%) and within 3 years (OR, 0.39; 95% CI, 0.19–0.80; P = .010; 9% vs 21%), whereas a trend toward lower risk was observed within 10 years (OR, 0.56; 95% CI, 0.29–1.08; P = .079; 16% vs 25%). Formal consultation, compared with informal or lack of consultation, improved outcomes at 1 year (OR, 0.16; 95% CI, 0.06–0.44; P < .001; 3% vs 14%), at 3 years (OR, 0.19; 95% CI, 0.09–0.42; P < .001; 5% vs 22%), and at 10 years (OR, 0.43; 95% CI, 0.24–0.74; P = .002; 27% vs 46%). Considering all prognostic parameters, formal consultation improved outcomes (HR, 0.42; 95% CI, 0.27–0.65; P < .001) and lowered risk for any new bacteremia (OR, 0.45; 95% CI, 0.23–0.88; P = .02) during 10 years of follow-up. Conclusions MS-SAB management by formal IDS consultation, compared with informal or lack of IDS consultation, reduces risk for new bacteremia episodes and improves long-term prognosis up to 10 years.

Abstract
BACKGROUND Staphylococcus aureus bacteremia (SAB) is associated with significant morbidity and mortality. We sought to identify factors associated with infectious diseases consultation (IDC) and understand how IDC associates with SAB patient management and outcomes. METHODS A multicentre retrospective study was performed between 2012 and 2014 in a large Canadian Health Zone in order to determine factors associated with IDC and performance of key quality of care determinants in SAB management and clinical outcomes. Factors subject to quality of care determinants were established a priori and studied for associations with IDC and 30-day all-cause mortality using multivariable analysis. RESULTS Of 961 SAB episodes experienced by 892 adult patients, 605 episodes received an IDC. Patients receiving IDC were more likely to have prosthetic valves and joints and to have community-acquired and known sources of SAB, but increasing age decreased IDC occurrence. IDC was the strongest independent predictor for quality of care performance metrics, including repeat blood cultures and echocardiography. Mortality at 30 days was 20% in the cohort, and protective factors included IDC, achievement of source control, targeted therapy within 48 hours, and follow-up blood cultures but not the performance of echocardiography. CONCLUSIONS There were significant gaps between the treatments and investigations that patients actually received for SAB and what is considered the optimal management of their condition. IDC is associated with improved attainment of targeted SAB quality of care determinants and reduced mortality rates. Based on our findings, we propose a policy of mandatory IDC for all cases of SAB to improve patient management and outcomes.

J Community Hosp Intern Med Perspect 2018; 8:321-325. [PMID: 30559938 PMCID: PMC6292366 DOI: 10.1080/20009666.2018.1537462] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2018] [Accepted: 10/15/2018] [Indexed: 11/08/2022] Open
Abstract
Objective: The objective of this study was to review the impact of an automatic email notification to infectious disease consultants. Design: Cases were identified from a community hospital system microbiology database by at least one positive blood culture. Records were reviewed both before (2013 and 2014) and after (2015 and 2016) the implementation of the automated email system (intervention). Prior to this policy, consultation with the infectious disease (ID) specialist was at the discretion of the primary team. Results: There were no significant differences in 30-day mortality between the two groups (18 vs 20%, p = 0.10). However, a trend of shorter hospital stays (12.2 vs 9.5 days, p = 0.03) and reduced 30 day readmissions (40% vs 19%, p = 0.03) was observed and antibiotics prescribed for complicated cases was more appropriate (57% vs 85%, p = 0.004). Conclusions: In this study population, the implementation of an automatic email generator to ID specialists was associated with a shorter hospital length of stay, less 30-day readmissions and more appropriate length of antibiotics prescribed in complicated cases of SAB. The authors recommend future studies replicating the methodology employed here with larger sample sizes before consideration of employing a similar automatic email ID consult generation at other health systems.

Abstract
Background Infectious specialist consultations (ISC) provide ever more evidence for improved outcome in Staphylococcus aureus bacteremia (SAB). Most ISC are formal (bedside). However, the impact of ISC on clinical management and prognosis lacks evaluation in aged patients with SAB. Methods Multicenter retrospective analysis of methicillin-sensitive (MS) SAB. Patients were stratified according to age ≥ 60 years (sub-analyses for ≥ 75 years and females) and formal (bedside) ISC given within 7 days of SAB diagnosis. The impact on management and outcome of formal ISC was explored. Statistics were performed with univariate analysis, Cox proportional hazards regression model analysis, including propensity-score adjustment, and graphic Kaplan–Meier interpretation. Results Altogether 617 patients were identified and 520 (84%) had formal ISC. Presence of formal ISC resulted in equivalent clinical management regardless of age over or under 60 years: localization and eradication of infection foci (80 vs. 82% and 34 vs. 36%) and use of anti-staphylococcal antibiotics (65 vs. 61%). Patients aged ≥ 60 years managed without formal ISC, compared to those with formal ISC, had less infection foci diagnosed (53 vs. 80%, p < 0.001). Lack of formal ISC in patients aged ≥ 60 years resulted in no infection eradication and absence of first-line anti-staphylococcal antibiotics. Formal ISC, compared to absence of formal ISC, lowered mortality at 90 days in patients aged ≥ 60 years (24 vs. 47%, p = 0.004). In Cox proportional regression, before and after propensity-score adjustment, formal ISC was a strong positive prognostic parameter in patients aged ≥ 60 years (HR 0.45; p = 0.004 and HR 0.44; p = 0.021), in patients aged ≥ 75 years (HR 0.18; p = 0.001 and HR 0.11; p = 0.003) and in female patients aged ≥ 75 years (HR 0.13; p = 0.005). Conclusion Formal ISC ensures proper active clinical management irrespective of age and improve prognosis in aged patients with MS-SAB.

Abstract
The impact of consultation by infectious diseases (ID) physicians on management and outcomes of patients has not been determined in China. We assembled a retrospective cohort of 995 consecutive adult cases with bloodstream infections (BSI) in a major teaching hospital in China. Survival analysis was performed with Cox regression and the Kaplan-Meier curves. Among the 995 patients with BSI, 421 (42.3%) received consultation by ID physicians and 574 (57.7%) did not. ID consultation led to a significant lower hazard of death (hazard ratio [HR], 0.575; P < 0.05) and more appropriate antimicrobial use (95.0% vs 67.6%, P < 0.05). ID consultation was a protective factor among patients with BSI due to Gram-positive (HR, 0.551; P < 0.05) or Gram-negative (HR, 0.331; P < 0.05) bacteria. Multiple ID consultation was a protective factor (HR, 0.51; P < 0.05), while single consultation was not. In conclusion, ID consultation led to significant lower risk for patients with BSI and improved management. Multiple rather than single ID consultations reduced the hazard of death.

Abstract
Infectious complications following treatment of acute myeloid leukemia (AML) are important causes of morbidity and mortality. The spectrum and complexity of these infections is reflected by the severe net state of immunosuppression of AML patients, that is dynamic and continuously changing, the polypharmacy, including the widespread use of anti-infectives and the complex epidemiology of severe and frequently resistant pathogens afflicting these patients. Infectious diseases (ID) consultants having a critical mass of expertise and intimate knowledge of the intricacies of leukemia care, add considerable value in improving outcomes of patients with AML who develop infections. Furthermore, pharmaco-economic considerations such as length of stay, choice of cost-effective anti-infective program, infection control and antibiotic stewardship strategies create a delicate interplay of the ID consultant and the ecosystem of care of AML patients. This is an increasingly recognized area of cross collaboration and a productive direction for future collaborative practice models and research.

Abstract
BACKGROUND Transplant Infectious Diseases (TID) is a rapidly growing subspecialty, which has contributed significantly to improving patient outcomes after transplantation. Obtaining institutional support to implement programs that promote excellence in patient care remains a challenge for many non-surgical transplant-related specialties. METHOD We surveyed the membership of the American Society of Transplantation Infectious Diseases Community of Practice to assess characteristics of individual transplant programs and delineate current patterns of institutional support of TID, with a goal of facilitating the exchange of innovative funding ideas between transplant programs. RESULTS Of 53 questionnaires returned, 36 programs reported the existence of a dedicated TID service for adults. Of these, the ratio of dedicated TID providers to the number of solid organ transplant patients transplanted annually ranged from 15:1 to 259:1. A total of 21% of responding programs indicated that they received no support from their institution. Respondents from larger programs were more likely to receive some type of programmatic support. CONCLUSION Given that the presence of expert TID input into patient care can improve outcomes through direct patient management and transplant team education, we suggest that continued support of the unbillable time contributed by TID practitioners is a critical part of ensuring excellent outcomes after transplantation.

Abstract
OBJECTIVE Previous studies have shown infectious diseases consultation (IDC) for Staphylococcus aureus bacteremia (SAB) improves management and outcomes. The influence of IDC on outcomes for SAB in addition to an antimicrobial stewardship program (ASP) review for adult inpatients with SAB has not been evaluated. The purpose of this study was to investigate the effect of IDC on SAB management with concomitant ASP review and resulting outcomes. METHODS Adult inpatients with SAB admitted December 2012-October 2014 were included. The primary end point compared adherence to Infectious Disease Society of America guideline recommendations between patients receiving an IDC versus those not receiving an IDC. We also evaluated adherence to the individual components of the primary end point and clinical outcomes, including time to microbiologic clearance, recurrence of bacteremia, mortality, and length of stay. RESULTS This study included 154 patients (115 IDC and 39 non-IDC). Guideline adherence was significantly greater in the IDC group 78% versus 46% in the non-IDC group (P < .001). Significantly more patients in the IDC group had echocardiography (91% vs 67%; P < .001) and follow-up blood cultures (92% vs 64%; P > .001). Mortality was also greater in the non-IDC group (23%) versus 5% for the IDC group (P = .001). CONCLUSIONS Patients with SAB receiving an IDC were more likely to receive guideline-congruent management and had significantly reduced mortality. No improvements in antibiotic choice or dosing were observed, likely a result of ASP review.

Abstract
INTRODUCTION Staphylococcus aureus bacteraemia (SAB) is a frequent infection with high mortality rates. It requires specific diagnostic and therapeutic management such as prolonged intravenous administration of antibiotics and aggressive search for and control of infectious sources. Underestimation of disease severity frequently results in delayed or inappropriate management of patients with SAB leading to increased mortality rates. According to observational studies, patient counselling by infectious disease consultants (IDC) improves survival and reduces the length of hospital stay as well as complication rates. In many countries, IDC are available only in some tertiary hospitals. In this trial, we aim to demonstrate that the outcome of patients with SAB in small and medium size hospitals that do not employ IDC can be improved by unsolicited ID phone counselling. The SUPPORT trial will be the first cluster-randomised controlled multicentre trial addressing this question. METHODS AND ANALYSIS SUPPORT is a single-blinded, multicentre interventional, cluster-randomised, controlled crossover trial with a minimum of 15 centres that will include 250 patients with SAB who will receive unsolicited IDC counselling and 250 who will receive standard of care. Reporting of SAB will be conducted by an electronic real-time blood culture registry established for the German Federal state of Thuringia (ALERTSNet) or directly by participating centres in order to minimise time delay before counselling. Mortality, disease course and complications will be monitored for 90 days with 30-day all-cause mortality rates as the primary outcome. Generalised linear mixed modelling will be used to detect the difference between the intervention sequences. We expect improved outcome of patients with SAB after IDC. ETHICS AND DISSEMINATION We obtained ethics approval from the Ethics committee of the Jena University Hospital and from the Ethics committee of the State Chamber of Physicians of Thuringia. Results will be published in a peer-reviewed journal and additionally disseminated through public media. TRIAL REGISTRATION NUMBER DRKS00010135.

Abstract
Previous reports have associated hyperglycemia to poor outcome among aged and comorbid Staphylococcus aureus bacteraemia (SAB) patients. However, the prognostic impact of hyperglycemia in SAB irrespective of age and underlying conditions including a diagnosis of diabetes has received little attention. The objective here was to evaluate the prognostic relevance of hyperglycemia at onset of methicillin-sensitive SAB (MS-SAB). It was a retrospective study of MS-SAB patients. Blood glucose was measured within 24 h of positive blood cultures. The patient cohort was analyzed en bloc and by categorization according to age, underlying conditions and a diagnosis of diabetes. Altogether 161 patients were identified. High initial blood glucose levels were observed among diabetics (p < 0.001), patients with deep infections (p < 0.05) and poor outcome at 28- or 90-days (p < 0.05). Receiver operating characteristics presented the glucose cut-off level of 7.2 mmol/L as a significant predictor of mortality with an area under the curve of 0.63 (95% CI 0.52-0.75, p < 0.05). Blood glucose ≥7.2 mmol/L connected to higher 28- (9 vs. 20%, p < 0.05) and 90-day (14 vs. 29%, p < 0.01) mortality. In Cox proportional hazard regression the blood glucose cut-off value of 7.2 mmol/L significantly predicted 90-day mortality (HR, 2.12; 95% CI, 1.01-4.46; p < 0.05). Among young and healthy non-diabetics the negative prognostic impact of high glucose was further accentuated (HR 7.46, p < 0.05). High glucose levels had no prognostic impact among diabetics. Hyperglycemia at SAB onset may associate to poor outcome. The negative prognostic impact is accentuated among young and healthy non-diabetics.

Abstract
BACKGROUND Echocardiography is fundamental for diagnosing infective endocarditis (IE) in patients with Staphylococcus aureus bacteremia (SAB), but whether all such patients require transesophageal echocardiography (TEE) is controversial. METHODS We identified SAB cases between February 2008 and April 2012. We compared sensitivity and specificity of transthoracic echocardiography (TTE) and TEE for evidence of IE, and we determined impacts of IE risk factors and TTE image quality on comparative sensitivities of TTE and TEE and their impact on clinical decision making. RESULTS Of 215 evaluable SAB cases, 193 (90%) had TTE and 130 (60%) had TEE. In 119 cases with both tests, IE was diagnosed in 29 (24%), for whom endocardial involvement was evident in 25 (86%) by TEE, vs only 6 (21%) by TTE (P < .001). Transesophageal echocardiography was more sensitive than TTE regardless of risk factors. Even among the 66 cases with adequate or better quality TTE images, sensitivity was only 4 of 17 (24%) for TTE, vs 16 of 17 (94%) for TEE (P < .001). Among 130 patients with TEE, the TEE results, alone or with TTE results, influenced treatment duration in 56 (43%) cases and led to valve surgery in at least 4 (6%). It is notable that, despite vigorous efforts to obtain both tests routinely, TEE was not done in 86 cases (40%) for various reasons, including pathophysiological contraindications (14%), patient refusal or other patient-related factors (16%), and provider declination or system issues (10%). CONCLUSIONS Patients with SAB should undergo TEE when possible to detect evidence for IE, especially if the results might affect management.

Abstract
The prognostic impact of thrombocytopaenia in Staphylococcus aureus bacteraemia (SAB) has previously been determined at bacteraemia onset only and relevant pre-bacteraemic thrombocytopaenia predisposing parameters have not been accounted for. We evaluated the prognostic impact of low thrombocyte count in SAB excluding pre-bacteraemic factors potentially causing thrombocytopaenia. This was a multicentre retrospective analysis of methicillin-sensitive SAB (MS-SAB) patients. Thrombocyte count was determined at blood culture collection and at days 3 and 7. Thrombocytopaenia was defined as a thrombocyte count less than 150 ×109/L. Patients with chronic alcoholism, liver diseases and haematologic malignancies were excluded. Altogether, 495 patients were identified. Thrombocytopaenia at blood culture and at day 3 associated to endocarditis (p < 0.05 and p < 0.01) and defervescence (p < 0.001 and p < 0.01). Mortality at 90 days was higher for patients with thrombocytopaenia at blood culture collection (26 vs. 16%, p < 0.05), at day 3 (32 vs. 13%, p < 0.01) and at day 7 (50 vs. 14%, p < 0.001). In receiver operating characteristic analyses, thrombocytopaenia predicted a poor outcome at blood culture collection (p < 0.05), at day 3 (p < 0.001) and at day 7 (p < 0.001). When accounting for all prognostic parameters, thrombocytopaenia at day 3 [hazard ratio (HR), 1.83; p = 0.05] demonstrated a trend towards poor outcome, whereas thrombocytopaenia at day 7 (HR, 3.64; p < 0.001) associated to poor outcome. Thrombocytopaenia at blood culture collection was not a prognostic parameter when all prognostic factors were taken into account. However, thrombocytopaenia at day 3 indicated a poor outcome and thrombocytopaenia at day 7 was a significant independent negative prognostic marker that has not been previously reported in SAB.

Abstract
Staphylococcus aureus is a common cause of severe bloodstream infection. We performed a systematic review to assess whether consultation with infectious disease specialists decreased all-cause mortality or rate of complications of S aureus bloodstream infections. The review also assessed parameters associated with the quality of management of the infection. We searched for eligible studies in PubMed, Embase, Scopus, and clinical trials.gov as well as the references of included studies. We identified 22 observational studies and 1 study protocol for a randomized trial. A meta-analysis was not performed because of the high risk of bias in the included studies. The outcomes are reported in a narrative review. Most included studies reported survival benefit, in the adjusted analysis. Recommended management strategies were carried out significantly more often among patients seen by an infectious disease specialist. Trials, such as cluster-randomized controlled trials, can more validly assess the studies at low risk of bias.

Eur J Clin Microbiol Infect Dis 2016; 35:471-9. [PMID: 26768583 DOI: 10.1007/s10096-015-2563-y] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2015] [Accepted: 12/16/2015] [Indexed: 12/21/2022]
Abstract
The purpose of this study was to examine the prognostic impact of corticosteroids in hemodynamically stabile Staphylococcus aureus bacteremia (SAB). There were 361 hemodynamically stabile methicillin-sensitive SAB patients with prospective follow-up and grouping according to time-point, dose and indication for corticosteroid therapy. To enable analyses without external interfering corticosteroid therapy all patients with corticosteroid therapy equivalent to prednisone >10 mg/day for ≥1 month prior to positive blood culture results were excluded. Twenty-five percent (92) of patients received corticosteroid therapy of which 11 % (40) had therapy initiated within 1 week (early initiation) and 9 % (31) had therapy initiated 2-4 weeks after (delayed initiation) positive blood culture. Twenty-one patients (6 %) had corticosteroid initiated after 4 weeks and were not included in the analyses. A total of 55 % (51/92) received a weekly prednisone dose >100 mg. Patients with early initiated corticosteroid therapy had higher mortality compared to patients treated without corticosteroid therapy at 28 days (20 % vs. 7 %) (OR, 3.11; 95%CI, 1.27-7.65; p < 0.05) and at 90 days (30 % vs. 10 %) (OR, 4.01; 95%CI, 1.82-8.81; p < 0.001). Considering all prognostic markers, early initiated corticosteroid therapy predicted 28-day (HR, 3.75; 95%CI, 1.60-8.79; p = 0.002) and 90-day (HR, 3.10; 95%CI, 1.50-6.39; p = 0.002) mortality in Cox proportional hazards regression analysis. When including only patients receiving early initiated corticosteroid therapy with prednisone ≥100 mg/week the negative prognostic impact on 28-day mortality was accentuated (HR 4.8, p = 0.001). Corticosteroid therapy initiation after 1 week of positive blood cultures had no independent prognostic impact. Early initiation of corticosteroid therapy may be associate to increased mortality in hemodynamically stabile SAB.

Abstract
BACKGROUND Staphylococcus aureus bacteremia (SAB) is associated with significant morbidity and mortality in hospitalized adults. OBJECTIVE We aimed to identify current practice patterns in the management of SAB, and to evaluate their association with clinical outcomes. DESIGN Retrospective cohort study. SETTING A 1558-bed tertiary care teaching hospital. PATIENTS Adult patients hospitalized between January 1, 2012 through April 30, 2013, who had at least 1 positive blood culture with S aureus. INTERVENTION None MEASUREMENTS Electronic medical records were reviewed and the processes of care in the management of SAB were identified. The main outcome was clinical failure, defined as a composite endpoint of in-hospital mortality and persistent bacteremia. RESULTS Two hundred fifty episodes of SAB occurred in 241 patients, and 78 (32.4%) had clinical failure. Processes of care that impacted the risk of clinical failure included: timing of follow-up blood cultures (delays of >4 days had a relative risk [RR] of 6.6; 95% confidence interval [CI]: 2.1-20.5; P = 0.001), consultation with infectious diseases specialist within 6 days from diagnosis of SAB (RR: 0.3; 95% CI: 0.1-0.9; P = 0.03), and use of β-lactams in patients with methicillin-susceptible S aureus bacteremia (RR: 0.1; 95% CI: 0.04-0.5; P = 0.002). CONCLUSIONS The processes of care identified in our study could serve as quality and patient safety indicators for the management of SAB.

Management and outcomes in patients with Staphylococcus aureus bacteremia after implementation of mandatory infectious diseases consult: a before/after study. BMC Infect Dis 2015; 15:568. [PMID: 26666459 PMCID: PMC4678701 DOI: 10.1186/s12879-015-1296-y] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2015] [Accepted: 11/26/2015] [Indexed: 11/30/2022] Open
Abstract
Background Infectious disease (ID) consultations have been shown to increase adherence to guidelines and decrease mortality for patients with Staphylococcus aureus bacteremia (SAB). Here, we assessed the impact of a mandatory ID consultation policy for SAB. Methods We retrospectively reviewed all consecutive adult patients with SAB at two tertiary care teaching hospitals in Hamilton, ON, Canada. Mandatory ID consults for SAB were implemented on January 1st 2012. We compared SAB cases in 2011 (control group) with those in 2012 (intervention group). Outcomes included adherence to the Infectious Diseases Society of America guidelines and patient outcomes. Results We reviewed 128 SAB cases in 2011 and 124 in 2012. The majority of S. aureus were methicillin-susceptible (97/128, 75.8 % in 2011 and 100/124, 80.6 % in 2012). ID involvement increased significantly from 93/128 (72.7 %) in 2011, to 103/124 (83.1 %) in 2012 (odds ratio [OR] 1.9, 95 % confidence interval [CI] 1.1–3.3, p = 0.047). There was also a significant decrease in the median time to ID involvement from 2 days to 1 (p = 0.001). In patients who survived the minimum treatment course (greater than 13 days), there was a significant improvement in adherence to IDSA guidelines in 2012 (65/102, 63.7 % vs. 77/96, 80.2 %; OR 2.3, 95 % CI 1.2–4.4, p = 0.01). Mortality and SAB relapse rates were similar in both groups. Conclusions Creating an automated ID consultation for SAB led to an increase in involvement of ID, a significant decrease in time to ID involvement, and better adherence to IDSA guidelines. The study was not sufficiently powered to detect significant changes in mortality and SAB relapse rates.

Abstract
OBJECTIVE Mortality and morbidity of Staphylococcus aureus bacteremia (SAB) still remains considerably high. We aimed to evaluate the impact of infectious disease consultation (IDC) on the management and outcomes of patients with SAB. METHODS We systematically searched 3 publication databases from inception to 31st May 2015 and reference lists of identified primary studies. RESULTS Our search returned 2874 reports, of which 18 fulfilled the inclusion criteria, accounting for 5337 patients. Overall 30-day mortality was 19.95% [95% CI 14.37-27.02] with a significant difference in favour of the IDC group (12.39% vs 26.07%) with a relative risk (RR) of 0.53 [95% CI 0.43-0.65]. 90-day mortality and relapse risk for SAB were also reduced significantly with RRs of 0.77 [95% CI 0.64-0.92] and 0.62 [95% CI 0.39-0.99], respectively. Both, the appropriateness of antistaphylococcal agent and treatment duration was improved by IDC (RR 1.14 [95% CI 1.08-1.20] and 1.85 [95% CI 1.39-2.46], respectively). Follow-up blood cultures and echocardiography were performed more frequently following IDC (RR 1.35 [95% CI 1.25-1.46] and 1.98 [95% CI 1.66-2.37], respectively). CONCLUSIONS Evidence-based clinical management enforced by IDC may improve outcome of patients with SAB. Well-designed cluster-randomized controlled trials are needed to confirm this finding from observational studies.

Abstract
Staphylococcus aureus is a major human pathogen that causes a wide range of clinical infections. It is a leading cause of bacteremia and infective endocarditis as well as osteoarticular, skin and soft tissue, pleuropulmonary, and device-related infections. This review comprehensively covers the epidemiology, pathophysiology, clinical manifestations, and management of each of these clinical entities. The past 2 decades have witnessed two clear shifts in the epidemiology of S. aureus infections: first, a growing number of health care-associated infections, particularly seen in infective endocarditis and prosthetic device infections, and second, an epidemic of community-associated skin and soft tissue infections driven by strains with certain virulence factors and resistance to β-lactam antibiotics. In reviewing the literature to support management strategies for these clinical manifestations, we also highlight the paucity of high-quality evidence for many key clinical questions.

Abstract
IMPORTANCE Several management strategies may improve outcomes in patients with Staphylococcus aureus bacteremia. OBJECTIVES To review evidence of management strategies for S. aureus bacteremia to determine whether transesophageal echocardiography is necessary in all adult cases and what is the optimal antibiotic therapy for methicillin-resistant S. aureus (MRSA) bacteremia. EVIDENCE REVIEW A PubMed search from inception through May 2014 was performed to identify studies addressing the role of transesophageal echocardiography in S. aureus bacteremia. A second search of PubMed, EMBASE, and the Cochrane Library from January 1990 through May 2014 was performed to find studies addressing antibiotic treatment for MRSA bacteremia. Studies reporting outcomes from antibiotic therapy for MRSA bacteremia were included. All searches, which were limited to English and focused on adults, were augmented by review of bibliographic references from included studies. The quality of evidence was assessed using the Grades of Recommendation, Assessment, Development and Evaluation system with consensus of independent evaluations by at least 2 of the authors. FINDINGS In 9 studies with a total of 4050 patients, use of transesophageal echocardiography was associated with higher rates of a diagnosis of endocarditis (14%-28%) compared with transthoracic echocardiography (2%-15%). In 4 studies, clinical or transthoracic echocardiography findings did not predict subsequent transesophageal echocardiography findings of endocarditis. Five studies identified clinical or transthoracic echocardiography characteristics associated with low risk of endocarditis (negative predictive values from 93% to 100%). Characteristics associated with a low risk of endocarditis include absence of a permanent intracardiac device, sterile follow-up blood cultures within 4 days after the initial set, no hemodialysis dependence, nosocomial acquisition of S. aureus bacteremia, absence of secondary foci of infection, and no clinical signs of infective endocarditis. Of 81 studies of antibiotic therapy for MRSA bacteremia, only 1 high-quality trial was identified. In that study of 246 patients with S. aureus bacteremia, daptomycin was not inferior to vancomycin or an antistaphylococcal penicillin, each in combination with low-dose, short-course gentamicin (clinical success rate, 44.2% [53/120] vs 41.7% [48/115]; absolute difference, 2.4% [95% CI, -10.2% to 15.1%]). CONCLUSIONS AND RELEVANCE All adult patients with S. aureus bacteremia should undergo echocardiography. Characteristics of low-risk patients with S. aureus bacteremia for whom transesophageal echocardiography can be safely avoided have been identified. Vancomycin and daptomycin are the first-line antibiotic choices for MRSA bacteremia. Well-designed studies to address the management of S. aureus bacteremia are needed.

Abstract
BACKGROUND There has been a paucity of data on the healthcare resource utilization of infectious disease-related complications in solid organ transplant recipients. The aims of this study were to report the clinical and economic burden of infectious disease-related complications, along with the impact of infectious disease consultation. METHODS This cohort study evaluated patients requiring admission to a tertiary-care center during 2007, 2008, and 2011. Propensity score matching was used to estimate the effects of patient demographics, comorbidities, and transplant- and infection-related factors on 28-day hospital survival, length of stay (LOS), and medical costs. RESULTS Infectious disease-related complications occurred in 603 of 1414 (43%) admissions in 306 of 531 (58%) patients. Unadjusted 28-day mortality did not differ between those who received infectious disease consultations vs those who did not (2.9% vs 3.6%, P = .820), however, after propensity score matching, infectious disease consultation resulted in significantly greater 28-day survival estimates (hazard ratio = 0.33; log-rank P = .026), and reduced 30-day rehospitalization rates (16.9% vs 23.9%, P = .036). The median LOS and hospitalization costs were significantly increased for patients receiving an infectious disease consultation than in those managed by the attending team alone (7.0 vs 5.0 days, P = .002, and $9652 vs $6192, P = .003). However, the median LOS (5.5 vs 5.1 days, P = .31) and hospitalization costs ($8106 vs $6912, P = .63) did not differ significantly among those receiving an early infectious disease consultation (<48 hours) vs no consultation, respectively. CONCLUSIONS Infectious disease consultation in recipients of solid organ transplant is associated with increased LOS and hospitalization costs but decreased mortality and reduced rehospitalization rates. Early consultation with infectious disease specialists decreases healthcare resource utilization compared with delayed referrals.

Abstract
PURPOSE OF REVIEW Traditional utilization of infectious diseases consultants by oncologists ranges from inpatient management of a variety of acute infectious syndromes to management of ambulatory patients with acute or chronic infections; however, there is a paucity of data to evaluate in which circumstances the impact of infectious diseases input may be most valuable. RECENT FINDINGS Data derived from the general population of patients emphasize the value of infectious diseases consultation in specific infections, such as Staphylococcus aureus bacteremia, candidemia, and hepatitis C virus infection. In addition, infectious diseases involvement has been associated with greater adherence to guidelines (up to 34% increase), more appropriate antibiotic utilization (up to 52% increase in appropriate duration), decreased cost and complications of care, and lower mortality (up to 17% decrease). Recent studies suggest that bedside, formal infectious diseases consultation is more optimal than informal interactions (e.g., e-mail, telephone, other). Furthermore, infectious diseases consultants play central roles in antibiotic stewardship, infection control, and quality improvement, particularly in oncology centers. SUMMARY Infectious diseases consultants contribute value in various inpatient and outpatient infections, decreasing mortality, cost, and complications.
