Decreasing the Time to Administration of First Dose of Antibiotics in Children With Severe Sepsis

Association between emergency department sepsis order set design and delay to second dose piperacillin-tazobactam administration

BACKGROUND

Delay to first antibiotic dose in patients with sepsis has been associated with increased mortality. Second dose antibiotic delay has also been linked to worsened patient outcomes. Optimal methods to decrease second dose delay are currently unclear. The primary objective of this study was to evaluate the association between updating an emergency department (ED) sepsis order set design from one-time doses to scheduled antibiotic frequencies and delay to administration of second piperacillin-tazobactam dose.

METHODS

This retrospective cohort study was conducted at eleven hospitals in a large, integrated health system and included adult patients treated in the ED with at least one dose of piperacillin-tazobactam ordered through an ED sepsis order set over a two year period. Patients were excluded if they received less than two doses of piperacillin-tazobactam. Midway through the study period, the enterprise-wide ED sepsis order set was updated to include scheduled antibiotic frequencies. Two patient cohorts receiving piperacillin-tazobactam were compared: those in the year before the order set update and those in the year post-update. The primary outcome was major delay, defined as an administration delay >25% of the recommended dosing interval, which was evaluated with multivariable logistic regression and interrupted time series analysis.

RESULTS

3219 patients were included: 1222 in the pre-update group and 1997 in the post-update group. The proportion of patients who experienced major second dose delay was significantly lower in the post-update group (32.7% vs 25.6%, p < 0.01; adjusted OR 0.64, 95% CI 0.52 to 0.78). No between-group difference was detected in the slope of monthly major delay frequency, but there was a significant level change (post-update change -10%, 95% CI -17.9% to -1.9%).

CONCLUSIONS

Including scheduled antibiotic frequencies in ED sepsis order sets is a pragmatic mechanism to decrease delays in second antibiotic doses.

Advances in Shock Management and Fluid Resuscitation in Children

Shock in children is associated with significant mortality and morbidity, particularly in resource-limited settings. The principles of management include early recognition, fluid resuscitation, appropriate inotropes, antibiotic therapy in sepsis, supportive therapy for organ dysfunction, and regular hemodynamic monitoring. During the past decade, each step has undergone several changes and evolved as evidence that has been translated into recommendations and practice. There is a paradigm shift from protocolized-based care to personalized management, from liberal strategies to restrictive strategies in terms of fluids, blood transfusion, ventilation, and antibiotics, and from clinical monitoring to multimodal monitoring using bedside technologies. However, uncertainties are still prevailing in terms of the volume of fluids, use of steroids, and use of extracorporeal and newer therapies while managing shock. These changes have been summarized along with evidence in this article with the aim of adopting an evidence-based approach while managing children with shock.

Development of a Novel Assessment Tool and Code Sepsis Checklist for Neonatal Late-Onset Sepsis

BACKGROUND

Accurate diagnosis and timely management of neonatal late-onset sepsis (nLOS) have been less well-studied than those of early-onset sepsis. We noticed a delay in nLOS detection and management in our neonatal intensive care unit.

PURPOSE

To develop an assessment tool to aid in the recognition and reporting of nLOS and to standardize the management process once sepsis is recognized.

METHODS

The Plan-Do-Study-Act (PDSA) improvement model provided the framework for interventions for our antibiotic stewardship program, including the aims of this project. A literature review was performed to evaluate tools and other literature available to guide the evaluation and management of suspected sepsis. A quality improvement project was initiated to develop tools for the detection and management of nLOS.

RESULTS

An nLOS assessment tool to help identify neonates at risk for nLOS and a Code Sepsis checklist to standardize the process of evaluation and management of nLOS were developed. The guiding principles of this tool development were empowerment of nurses to initiate the assessment process, clarification of team roles, and removal of barriers to appropriate antibiotic administration.

IMPLICATIONS FOR PRACTICE

Useful and practical tools valued by nursing and the multidisciplinary team may facilitate timely identification and treatment of infants with nLOS.

IMPLICATIONS FOR RESEARCH

Future directions include validation of the nLOS assessment tool and the Code Sepsis checklist as well as ensuring the reliability of the tool to improve detection of nLOS and to reduce time to administer antibiotics in cases of nLOS.

Predictor of Early Administration of Antibiotics and a Volume Resuscitation for Young Infants with Septic Shock

(1) Background: It is critical to administer antibiotics and fluid bolus within 1 h of recognizing sepsis in pediatric patients. This study aimed to identify the predictor of the successful completion of a 1-h sepsis bundle for infants with suspected sepsis. (2) Methods: This is an observational study using a prospective registry including febrile young infants (aged < 90 days) who visited a pediatric emergency department with a core body temperature of 38.0 °C or higher and 36.0 °C or lower. Univariate and logistic regression analyses were conducted to determine the predictor (s) of successful sepsis bundle completion. (3) Results: Of the 323 registered patients, 118 patients with suspected sepsis were analyzed, and 38 patients (32.2%) received a bundle-compliant treatment. Among potential variables, such as age, sex, and vital sign parameters, the logistic regression analysis showed that heart rate (odds ratio: OR 1.02; 95% confidence interval: 1.00-1.04) is a significant predictor of the completion of a 1-h sepsis bundle. (4) Conclusions: We found that tachycardia facilitated the sepsis recognition and promoted the successful completion of a 1-h sepsis bundle for young infants with suspected septic shock and a possible indicator for improving the quality of the team-based sepsis management.

Delayed Administration of Antibiotics Beyond the First Hour of Recognition Is Associated with Increased Mortality Rates in Children with Sepsis/Severe Sepsis and Septic Shock

OBJECTIVE

To compare the risk of mortality and other clinical outcomes in children with sepsis, severe sepsis, or septic shock who received antibiotics within the first hour of recognition (early antibiotics group) with those who received antibiotics after the first hour (delayed antibiotics group).

STUDY DESIGN

In this prospective cohort study, we enrolled children <17 years of age presenting to the pediatric emergency and diagnosed with sepsis or septic shock without prior antibiotic therapy. Primary outcome was mortality and the secondary outcomes were day 1 Pediatric Logistic Organ Dysfunction score, ventilator-free days, and hospital-free days. These outcomes were compared between the early and the delayed antibiotic groups. The reference point for defining early and delayed antibiotic groups was time 0, which was measured from the time the patient was diagnosed to have sepsis, severe sepsis, or septic shock to the time of administration of the first dose of antibiotics.

RESULTS

About three-fourths (77%) of the 441 children enrolled had septic shock. A total of 241 (55%) and 200 (45%) children were in the delayed and early antibiotic groups, respectively. Children in the delayed group had significantly higher odds of mortality than those in the early group (29% vs 20%; aOR 1.83; 95% CI, 1.14-2.92; P = .01). The time to shock reversal was significantly shorter, and the ventilator-free days and hospital-free days were significantly greater, in the early antibiotic group. There was no difference between the groups with regard to any of the other clinical outcomes.

CONCLUSIONS

Delayed administration of antibiotics beyond 1 hour of recognition was associated with higher mortality rates in children with sepsis, severe sepsis, and septic shock. Antibiotics should be administered within the first hour, along with other resuscitative measures, in these children.
