Infectious diseases specialist consultation in Staphylococcus lugdunensis 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.

The Impact of Infectious Disease Specialist Consultation for Staphylococcus aureus Bloodstream Infections: A Systematic Review.

Project description: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.

Impact of infectious diseases consultation on the management of Staphylococcus aureus bacteraemia in children.

Project description:ObjectivesInfectious diseases consultation (IDC) in adults with Staphylococcus aureus bacteraemia (SAB) has been shown to improve management and outcome. The aim of this study was to evaluate the impact of IDC on the management of SAB in children.Study designObservational cohort study of children with SAB.SettingCambridge University Hospitals National Health Service (NHS) Foundation Trust, a large acute NHS Trust in the UK.ParticipantsAll children with SAB admitted to the Cambridge University Hospitals NHS Foundation Trust between 16 July 2006 and 31 December 2012.MethodsChildren with SAB between 2006 and 31 October 2009 were managed by routine clinical care (pre-IDC group) and data were collected retrospectively by case notes review. An IDC service for SAB was introduced in November 2009. All children with SAB were reviewed regularly and data were collected prospectively (IDC group) until 31 December 2012. Baseline characteristics, quality metrics and outcome were compared between the pre-IDC group and IDC group.ResultsThere were 66 episodes of SAB in 63 children-28 patients (30 episodes) in the pre-IDC group, and 35 patients (36 episodes) in the IDC group. The median age was 3.4 years (IQR 0.2-10.7 years). Patients in the IDC group were more likely to have echocardiography performed, a removable focus of infection identified and to receive a longer course of intravenous antimicrobial therapy. There were no differences in total duration of antibiotic therapy, duration of hospital admission or outcome at 30 or 90 days following onset of SAB.ConclusionsIDC resulted in improvements in the investigation and management of SAB in children.

Impact of Infectious Diseases Consultation on the Outcome of Patients With Enterococcal Bacteremia: A Systematic Literature Review and Meta-analysis.

Project description:BackgroundEnterococcal 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 was conducted to determine whether IDC is associated with a mortality benefit among patients with enterococcal bacteremia.MethodsWe 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-effects models were used to calculate pooled odds ratios (pORs). Heterogeneity was evaluated using I 2 estimation and the Cochran's Q statistic test.ResultsThe systematic literature review revealed 6496 reports, from which 18 studies were evaluated in the 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 substantial heterogeneity (I 2 = 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 (I 2 = 0%). Some studies also showed additional benefits to IDC, including appropriate antibiotic therapy and improved diagnostic use.ConclusionsIDC was associated with 60% lower odds of mortality when patients were well-matched, potentially through improvement in the care of patients with enterococcal bacteremia. IDC should be considered part of routine care for patients with enterococcal bacteremia.

Clinical Reasoning of Infectious Diseases Physicians Behind the Use or Nonuse of Transesophageal Echocardiography in <i>Staphylococcus aureus</i> Bacteremia.

Project description:In this prospective cohort with Staphylococcus aureus bacteremia, transesophageal echocardiography (TEE) was performed in 24% of cases. Consulting Infectious Diseases physicians most frequently cited low suspicion for endocarditis due to rapid clearance of blood cultures and the presence of a secondary focus requiring an extended treatment duration as reasons for foregoing TEE.

Non-infectious diseases in infectious disease consultation: A descriptive study in a tertiary care teaching hospital.

Project description:In this retrospective study, we aimed to investigate the frequency, trend, and nature of non-infectious diseases (non-IDs) as the final diagnosis for patients during an infectious disease (ID) consultation in an acute care hospital in Japan. This study included adult inpatients who underwent ID consultations between October 2016 and March 2018. The demographic data, clinical manifestations, and final non-ID diagnoses of cases were explored. Among the 502 patients who underwent ID consultations, 45 (9.0%) were diagnosed with non-IDs. The most common diagnoses were tumors (22.2%, n = 10), connective tissue and collagen vascular diseases (13.3%, n = 6), other inflammatory diseases (8.9%, n = 4), and drug-induced fever (8.9%, n = 4). Multiple logistic regression analysis showed that the presence of consultations for diagnosis (odds ratio [OR], 22.0; 95% confidence interval [CI], 10.1-48.2; p<0.01), consultations from the internal medicine department (OR, 2.5; 95% CI, 1.2-5.2; p = 0.02), and non-bacteremia cases (OR, 5.2; 95% CI, 1.4-19.3; p = 0.01) were independently associated with diagnosed non-IDs. Non-IDs after ID consultations were mainly tumor-related, inflammatory diseases, and drug fever. The presence of consultations for diagnosis, consultations from the internal medicine department and non-bacteremia cases were related to non-IDs among ID consultations. Further research is needed to explore the frequency and pattern of non-IDs to improve the quality of ID consultations in daily practice.

Mouse models for infectious diseases caused by Staphylococcus aureus.

Project description:Staphylococcus aureus - a commensal of the human skin, nares and gastrointestinal tract - is also a leading cause of bacterial skin and soft tissue infection (SSTIs), bacteremia, sepsis, peritonitis, pneumonia and endocarditis. Antibiotic-resistant strains, designated MRSA (methicillin-resistant S. aureus), are common and represent a therapeutic challenge. Current research and development efforts seek to address the challenge of MRSA infections through vaccines and immune therapeutics. Mice have been used as experimental models for S. aureus SSTI, bacteremia, sepsis, peritonitis and endocarditis. This work led to the identification of key virulence factors, candidate vaccine antigens or immune-therapeutics that still require human clinical testing to establish efficacy. Past failures of human clinical trials raised skepticism whether the mouse is an appropriate model for S. aureus disease in humans. S. aureus causes chronic-persistent infections that, even with antibiotic or surgical intervention, reoccur in humans and in mice. Determinants of S. aureus evasion from human innate and adaptive immune responses have been identified, however only some of these are relevant in mice. Future research must integrate these insights and refine the experimental mouse models for specific S. aureus diseases to accurately predict the failure or success for candidate vaccines and immune-therapeutics.

Black Box Warning: Large Language Models and the Future of Infectious Diseases Consultation.

Project description:Large language models (LLMs) are artificial intelligence systems trained by deep learning algorithms to process natural language and generate text responses to user prompts. Some approach physician performance on a range of medical challenges, leading some proponents to advocate for their potential use in clinical consultation and prompting some consternation about the future of cognitive specialties. However, LLMs currently have limitations that preclude safe clinical deployment in performing specialist consultations, including frequent confabulations, lack of contextual awareness crucial for nuanced diagnostic and treatment plans, inscrutable and unexplainable training data and methods, and propensity to recapitulate biases. Nonetheless, considering the rapid improvement in this technology, growing calls for clinical integration, and healthcare systems that chronically undervalue cognitive specialties, it is critical that infectious diseases clinicians engage with LLMs to enable informed advocacy for how they should-and shouldn't-be used to augment specialist care.

Impact of Infectious Diseases Consultation on Mortality of Cryptococcal infection in Patients without HIV.

Project description:Background:An infectious disease (ID) consultation is often obtained to treat patients with cryptococcosis due to the complex nature of the disease, but has never been demonstrated to impact outcomes. Methods:We assembled a retrospective cohort of 147 consecutive cases of cryptococcosis in patients without HIV. Patients who were diagnosed less than 24 hours prior to death were excluded. Survival analysis was performed with Cox regression with survival censored past 90 days. Results:The patients with an ID consult had a higher fungal burden but a lower 90-day mortality compared to patients without ID involvement (27% vs 45%, p<0.001), with an adjusted hazard ratio of not receiving an ID consult of 4.1 (95% CI: 2.2, 7.6). The ID consult group was more likely to receive an indicated lumbar puncture (86% vs 32%, p<0.001), and more likely to be treated with amphotericin B (AmB) (87% vs 24%, p<0.001) and flucytosine (5-FC) (57% vs 16%, p<0.001) when indicated. The duration of therapy with AmB (14 vs 11 days, p=0.05) and 5-FC (7.5 vs 1 days, p<0.001) was longer in the ID consult group. Conclusions:Patients that received an ID consult were significantly less likely to die in the 90 days following diagnosis. Patients seen by ID physicians were more likely to be managed according to evidence based practice established by randomized controlled trials and published in IDSA guidelines. These data suggest that an ID consult should be an integral part of clinical care of patients with cryptococcosis.

An Implementation Roadmap for Establishing Remote Infectious Disease Specialist Support for Consultation and Antibiotic Stewardship in Resource-Limited Settings.

Project description:Infectious Disease (ID)-trained specialists, defined as ID pharmacists and ID physicians, improve hospital care by providing consultations to patients with complicated infections and by leading programs that monitor and improve antibiotic prescribing. However, many hospitals and nursing homes lack access to ID specialists. Telehealth is an effective tool to deliver ID specialist expertise to resource-limited settings. Telehealth services are most useful when they are adapted to meet the needs and resources of the local setting. In this step-by-step guide, we describe how a tailored telehealth program can be implemented to provide remote ID specialist support for direct patient consultation and to support local antibiotic stewardship activities. We outline 3 major phases of putting a telehealth program into effect: pre-implementation, implementation, and sustainment. To increase the likelihood of success, we recommend actively involving local leadership and other stakeholders in all aspects of developing, implementing, measuring, and refining programmatic activities.
