Dr. Damian Roland, a Consultant in Paediatric Emergency Medicine at the University of Leicester NHS Trust, shares his expertise in managing pediatric sepsis. He discusses the critical need for early detection and effective interventions. The conversation dives into the complexities of diagnosing sepsis, questioning the effectiveness of current screening methods and lab tests. Roland critiques the misuse of 'sepsis screening' terminology, arguing it's more about clinical judgment and timing than standard tests. He highlights the challenges of pediatric fever assessments in emergency settings.
Sepsis diagnosis in pediatric patients is complex due to varied symptoms and the absence of definitive pathogens, necessitating careful clinical assessment.
Current sepsis screening practices are criticized for their lack of specificity, often leading to false positives and unnecessary interventions in pediatric care.
Deep dives
The Complexity of Sepsis Diagnosis in Pediatrics
Sepsis presents unique challenges in pediatric care primarily due to the complexities in its diagnosis. The definition of sepsis often encompasses various physiological responses, making it difficult to pinpoint when a child's condition transitions from simple infection to sepsis. Many children exhibit a spectrum of symptoms ranging from mild illness to severe sepsis, which complicates early recognition. This means that healthcare providers must navigate various stages of illness and understand that a definitive pathogen may not be present even when a child is highly symptomatic.
Critique of Current Sepsis Screening Practices
Current sepsis screening practices face criticism for their lack of specificity and poor predictive value. Many commonly employed scoring systems, such as vital sign abnormalities, generate numerous false positives, leading to unnecessary interventions. Studies have shown that a significant percentage of children who trigger sepsis alerts do not have invasive bacterial infections, indicating a gap between screening and actual clinical need. Consequently, reliance on these automated systems might lead to confusion and diminished trust among clinicians regarding their effectiveness.
Challenges in Sepsis Treatment Protocols
Debates surrounding the administration of fluids, inotropes, and antibiotics underline the challenges in sepsis treatment protocols. Recent guidance suggests that the urgency of administering antibiotics might not be as crucial as once thought, particularly in cases without clear organ dysfunction. Moreover, the appropriate volume and type of fluid to administer have been subjects of conflicting studies and opinions, leaving clinicians uncertain. Enhancing treatment requires balancing prompt intervention while avoiding fluid overload, emphasizing the necessity for more robust research in this domain.
The Role of Clinician Experience in Assessing Sepsis
Clinician experience plays a pivotal role in assessing pediatric patients for sepsis, particularly in overwhelmed healthcare settings. Decision-making often hinges on observing a child's trajectory of illness alongside parental concerns rather than solely relying on objective screening tools. There is a pressing need for clinicians to prioritize thorough assessments, even in high-pressure environments, to ensure that sick children receive appropriate care. Effective intervention requires both clinical judgment informed by experience and adequate time to evaluate each patient's unique circumstances.

Guest Skeptic: Dr. Damian Roland is a Consultant at the University of Leicester NHS Trust and Honorary Professor for the University of Leicester’s SAPPHIRE group. He specializes in Paediatric Emergency Medicine and is a passionate believer and advocate of FOAMed. Damian is also part of the Don’t Forget the Bubbles Team.
Dr. Damian Roland
Background: For anyone who has ever taken care of a decompensating child with septic shock, it’s unlikely you’ve forgotten the experience. So we have a lot of respect for sepsis and the importance of early recognition to prevent morbidity and mortality.
Despite the medical community’s experience with sepsis over the years, there is still much that is unclear about the diagnosis and management of sepsis:
How is sepsis diagnosed? What is the optimal fluid to give? How much fluid should be given? When should pressors be started? What pressors should be used? What is the optimal timing of antibiotic therapy?
We have covered the topic of sepsis a few times on the SGEM

Damian and Dr. Alasdair Munro make the bold claim in an opinion article in the BMJ titled, Time for paediatrics to screen out sepsis “screening.” Despite us being very careful in trying to identify children with sepsis, there is a lot of uncertainty. So, we're diving into some of those controversies and gray areas.
Some key topics are highlighted below, but tune into the podcast to listen to all the great conversation and pearls of wisdom from Dr. Roland.
Why Sepsis is a Challenge in Children’s Acute/Emergency Care?
The definition of "sepsis" is not clear.
Sepsis may be more due to the body's response to infection than the infection itself.
It's possible to have a pathogen in the bloodstream, but not have sepsis because there is not cardiac dysfunction or capillary leakage
Children with sepsis may not have a pathogen isolated, and children with a pathogen isolated may not be "septic."
What has been the Approach to Sepsis Recognition and Treatment?
Sepsis occurs along a spectrum. Recognizing severe sepsis is not difficult in the child that appears acutely ill. Distinguishing the children in the middle of that spectrum is a challenge.
There is variation in screening tools and scoring systems for sepsis across healthcare systems. The principle of evaluating for deranged physiology (abnormal vital signs) in combination with fever and infection risk is more ubiquitous. There are differences in application.
Screening tools are imperfect. There are many false positives and false negatives. There is no "holy grail" of screening tools.
We spoke about the utility of the following in detecting and ruling out sepsis:
lactate
inflammatory markers (CRP, ESR, procalcitonin)
viral PCR testing
height of fever
We also spoke some of the evidence behind management strategies for sepsis that included:
IV fluids
Inotropes
Antibiotics
Recent Controversies and Evidence
Many of us are familiar with the Surviving Sepsis campaign/International guidance.
After release a group of doctors expressed some concerns due to:
conflicts of interest
making strong recommendations based on weak evidence
criticism regarding the bundling of care that does not c...
