Detecting and Treating Sepsis in the Emergency Department

Association of IL-6 -174G > C Polymorphism with Susceptibility to Childhood Sepsis: A Systematic Review and Meta-Analysis

BackgroundThis meta-analysis evaluates the correlation between the IL-6 -174 G > C polymorphism and susceptibility of childhood sepsis. Methods: We searched PubMed, ISI Web of Knowledge, Scopus, CNKI, SID, SciELO databases until December 30, 2019 to identify all eligible studies. Results: A total of 17 studies with 1,287 cases and 2,482 controls were identified. Pooled data revealed that there was no significant association between the IL-6 -174 G > C polymorphism and risk childhood sepsis in the overall population. When stratified analysis was carried out by age group of cases, no associations were found in neonates and pediatrics. However, in ethnicity-based subgroups, a significant association was found in Caucasians and Africans. Conclusions: There was no significant association of the IL-6 -174G > C polymorphism with susceptibility to sepsis in childhood overall, but there was an association with the Caucasian and African ethnic subgroups.

Epidemiologic features and risk factors of sepsis in ischemic stroke patients admitted to intensive care: A prospective cohort study

BACKGROUND/OBJECTIVE

Stroke is the second leading cause of death globally that predisposed to sepsis. Therefore, this study was aimed to assess the risk factors and epidemiologic features of sepsis in ischemic stroke patients admitted to ICUs.

METHODS

Throughout this prospective study, we investigated all severe ischemic stroke patients admitted to ICUs of Namazi and Ali-Ashghar Hospitals in Shiraz. After ICU admission and diagnosing stroke by a neurologist according to NIHSS (National Institute of Health Stroke Scale) criteria, sepsis work-up was performed in all patients suspected to have sepsis. Then the incidence of sepsis and its risk factors in ICU admitted stroke patients were determined.

RESULTS

A total of 149 patients were screened in this study. The mean age of the participants was 65.37 ± 15.40 years old and 57.4% of them were male. Hypertension was the most common coexistent disease (74.6%) in stroke patients. Seventy-six patients (62.3%) were diagnosed with sepsis and pneumonia was the most common infection leading to sepsis in stroke patients. Our data showed significant differences between two groups in terms of APACHE-IV score (P < 0.001), NIHSS and APS (P < 0.001) before ICU admission (P < 0.001) and NIHSS at admission (P < 0.001); however, age (P = 0.07) and sex (P = 0.17) were not significantly different between the groups. Logistic regression analysis displayed that severe stroke (NIHSS = 21-42, OR = 49.09) and severe loss of consciousness (GCS < 8, OR = 27.95) at admission were the most essential predictive factors for sepsis after ischemic stroke.

CONCLUSIONS

This study showed that ICU patients with severe ischemic stroke were more susceptible to sepsis during the hospital course.

Utility of diagnostic blood tests in clinical podiatric medicine

Clinical podiatric medical practice encompasses a wide spectrum of podiatric medical and surgical problems. Technological advances such as imaging have greatly improved diagnostic acumen; however, physical diagnosis and blood testing remain extremely important factors in reinforcing diagnostic hypotheses as a part of differential diagnosis. There are certain blood tests of importance that the podiatric medical practitioner should be familiar with in everyday medical and surgical practice. The purpose of this article is to identify and highlight which blood tests are truly essential and practical in terms of diagnosis. This article encompasses blood tests pertinent to the clinical areas of hematology, hemostasis, electrolytes, endocrine, cardiac, rheumatology, nephrology, and gastroenterology. Careful selection of these tests and proper interpretation of their results will help reinforce diagnostic hypotheses.

Impact of nurse-initiated ED sepsis protocol on compliance with sepsis bundles, time to initial antibiotic administration, and in-hospital mortality

INTRODUCTION

Emergency nurses play a key role in the initial triage and care of patients with potentially life-threatening illnesses. The aims of this study were to (1) evaluate the impact of a nurse-initiated ED sepsis protocol on time to initial antibiotic administration, (2) ascertain compliance with 3-hour Surviving Sepsis Campaign (SSC) targets, and (3) identify predictors of in-hospital sepsis mortality.

METHODS

A retrospective chart review investigated all adult patients-admitted through either of 2 academic tertiary medical center emergency departments-who were discharged with a diagnosis of severe sepsis or septic shock (N = 195). Pre- and post-protocol implementation data examined both compliance with 3-hour SSC bundle targets and patient outcomes. Multivariate logistic regression analysis identified predictors of in-hospital mortality.

RESULTS

Serum lactate measurement (83.9% vs 98.7%, P = .003) and median time to initial antibiotic administration (135 minutes vs 108 minutes, P = .021) improved significantly after protocol implementation. However, one quarter of antibiotic administration times still exceeded the 3-hour target. Significant predictors of in-hospital mortality were respiratory dysfunction, central nervous system dysfunction, urinary tract infection, vasopressor administration, and patient body weight (P < .05). There were no in-hospital mortality rate differences between the pre- and post-protocol implementation groups.

DISCUSSION

Compliance with serum lactate measurement and blood culture collection goals approached 100% in the post-protocol group. However, compliance with medical interventions requiring multiple health care-provider involvement (ie, antibiotic and fluid administration) remained suboptimal. Efforts focused on multidisciplinary bundle elements are necessary to achieve full compliance with SSC targets.

Suspicion and treatment of severe sepsis. An overview of the prehospital chain of care

BACKGROUND

Sepsis is a life-threatening condition where the risk of death has been reported to be even higher than that associated with the major complications of atherosclerosis, i.e. myocardial infarction and stroke. In all three conditions, early treatment could limit organ dysfunction and thereby improve the prognosis.

AIM

To describe what has been published in the literature a/ with regard to the association between delay until start of treatment and outcome in sepsis with the emphasis on the pre-hospital phase and b/ to present published data and the opportunity to improve various links in the pre-hospital chain of care in sepsis.

METHODS

A literature search was performed on the PubMed, Embase (Ovid SP) and Cochrane Library databases.

RESULTS

In overall terms, we found a small number of articles (n = 12 of 1,162 unique hits) which addressed the prehospital phase. For each hour of delay until the start of antibiotics, the prognosis appeared to become worse. However, there was no evidence that prehospital treatment improved the prognosis.Studies indicated that about half of the patients with severe sepsis used the emergency medical service (EMS) for transport to hospital. Patients who used the EMS experienced a shorter delay to treatment with antibiotics and the start of early goal-directed therapy (EGDT). Among EMS-transported patients, those in whom the EMS staff already suspected sepsis at the scene had a shorter delay to treatment with antibiotics and the start of EGDT.There are insufficient data on other links in the prehospital chain of care, i.e. patients, bystanders and dispatchers.

CONCLUSION

Severe sepsis is a life-threatening condition. Previous studies suggest that, with every hour of delay until the start of antibiotics, the prognosis deteriorates. About half of the patients use the EMS. We need to know more about the present situation with regard to the different links in the prehospital chain of care in sepsis.

Early detection and treatment of severe sepsis in the emergency department: identifying barriers to implementation of a protocol-based approach

INTRODUCTION

Despite evidence to support efficacy of early goal-directed therapy for resuscitation of patients with severe sepsis and septic shock in the emergency department, implementation remains incomplete. To identify and address specific barriers at our institution and maximize benefits of a planned sepsis treatment initiative, a baseline assessment of knowledge, attitudes, and behaviors regarding detection and treatment of severe sepsis was performed.

METHODS

An online survey was offered to nurses and physicians in the emergency department of a major urban academic medical center. The questionnaire was designed to assess (1) baseline knowledge and self-reported confidence in identification of systemic inflammatory response syndrome and sepsis; (2) current practices in treatment; (3) difficulties encountered in managing sepsis cases; (4) perceived barriers to implementation of a clinical pathway based on early quantitative resuscitation goals; and (5) to elicit suggestions for improvement of sepsis treatment within the department.

RESULTS

Respondents (n = 101) identified barriers to a quantitative resuscitation protocol for sepsis. These barriers included the inability to perform central venous pressure/central venous oxygen saturation monitoring, limited physical space in the emergency department, and lack of sufficient nursing staff. Among nurses, the greatest perceived contributor to delays in treatment was a delay in diagnosis by physicians; among physicians, a delay in availability of ICU beds and nursing delays were the greatest barriers. Despite these issues, respondents indicated that a written protocol would be helpful to them.

DISCUSSION

Knowledge gaps and procedural hurdles identified by the survey will inform both educational and process components of an initiative to improve sepsis care in the emergency department.

Implementation of early goal-directed therapy for septic patients in the emergency department: a review of the literature

INTRODUCTION

The Surviving Sepsis Campaign outlines the elements of early goal-directed therapy when treating patients with sepsis in the emergency department. The success of these guidelines relies on their implementation in order to attain optimal patient outcomes. The purpose of this article is to review the literature regarding the implementation of the sepsis guidelines in emergency departments.

METHODS

Using the search terms systemic inflammatory response syndrome, emergency service, and sepsis, the Cumulative Index of Nursing and Allied Health, MEDLINE, and Cochrane database were searched for information pertaining to implementing early goal-directed therapy for sepsis in the emergency department.

RESULTS

Studies that discussed collaboration, preplanning, and education were able to implement monitoring of central venous pressure, mean arterial pressure, and central venous oxygen saturation. However, nursing interventions recommended by the Surviving Sepsis Campaign such as measuring urine output and obtaining blood cultures were less often considered.

DISCUSSION

This review provides some factors important for the successful implementation of the Surviving Sepsis Campaign guidelines. Operational and system issues significantly influenced the success of implementing sepsis protocols or bundles. More research is needed to overcome barriers to implementing early goal-directed therapy and to uncover which elements of the guidelines are most important and feasible to achieve optimal patient outcomes.
