Hospital Infections in Kids: Which Surveillance Method Wins?
"Uncover the most effective ways to track and prevent healthcare-associated infections (HAIs) in children's hospitals, ensuring a safer environment for our youngest patients."
Healthcare-associated infections (HAIs) are a significant concern in hospitals worldwide, leading to adverse outcomes and increased costs. Children, with their developing immune systems, are particularly vulnerable. Effective surveillance is crucial for identifying and controlling these infections, but the best approach can vary depending on available resources and the specific healthcare setting.
In 2012, South Africa mandated HAI surveillance but didn't specify the methods. This study, conducted at Tygerberg Children's Hospital, compares three surveillance methods – point prevalence surveys (PPSs), laboratory surveillance, and antimicrobial prescription tracking – against a prospective clinical surveillance method to determine which performs best in a resource-limited setting.
The goal is to guide healthcare facilities in selecting the most suitable HAI surveillance strategy, balancing accuracy with feasibility to improve patient safety and reduce the burden of infection.
Measuring the Burden
CDC FastStats reports that 1.9% of U.S. children ages 5–11 were in fair or poor health in 2024, while 5.9% missed 11 or more school days because of illness, injury, or disability. CDC publishes healthcare-associated infection reports to track progress and identify areas needing assistance. CMS hospital infection measures, developed by CDC and collected through the National Healthcare Safety Network, provide information on infections occurring during hospitalization.
Standard Prevention Practices
Standard infection-prevention approaches include measures that healthcare workers are expected to know, support, and apply, according to a narrative review. WHO identifies insufficient application of standard precautions, inadequate supplies, prolonged or incorrect invasive-device use, high-risk procedures, poor infrastructure, and overcrowding as contributors to healthcare-associated infections. In neonatal intensive care, checklists and protocols offer a structured way to ensure required steps are followed, and the cited report describes reduced infection rates when checklists were used during central-line insertion.
From Pediatric Medicine to Infection Control
The history of pediatric infectious diseases closely parallels the history of pediatrics because infections historically represented major causes of illness and death. The U.S. Maternal and Child Health Bureau timeline traces developments in maternal and child health, while the MCH Library describes nearly a century of accomplishments in the field. A separate history of hospital infection control follows its evolution from the 18th century to the present and highlights figures such as Florence Nightingale.
Decoding HAI Surveillance Methods: Which One Works Best?
The study evaluated three main HAI surveillance methods and they are described below:
- Point Prevalence Surveys (PPSs): Conducting surveys at specific points in time to determine the proportion of patients with HAIs.
- Laboratory Surveillance: Tracking infections based on laboratory results, such as blood cultures and urine tests.
- Antimicrobial Prescription Tracking: Monitoring the use of antibiotics to identify potential HAIs.
An Evolving Evidence Base
Recent work on hospital infections in children continues to examine how surveillance methods identify infections, risk factors, and preventable events. The evidence may vary by age group, clinical setting, infection type, and the quality of available reporting. Comparisons between methods therefore require attention to what each approach measures and what it may miss.
Where Surveillance Can Fall Short
Healthcare-associated infections remain part of a broader global problem of poor-quality care that also includes medical errors and surgical complications, contributing to patient morbidity and mortality. Healthcare-associated respiratory viral infections are described as a significant but under-reported threat for hospitalized children and may lead to prolonged admissions and worse outcomes. Research on children hospitalized with SARS-CoV-2 has also focused on identifying those at higher risk of severe disease and death, underscoring the need for surveillance that captures clinically important differences among patients.
Comparing Hospitals and Populations
California's public reporting system provides a detailed two-page healthcare-associated infection summary for each hospital and allows users to compare two or more hospitals side by side. A European survey analyzed pediatric data to estimate the prevalence and types of healthcare-associated infections among children and adolescents and to identify risk factors. These approaches serve different purposes: hospital profiles support facility-level comparison, while surveys can describe infection patterns and risk factors across pediatric populations.
Takeaways: Customizing Your HAI Surveillance Strategy
The research highlights that no single HAI surveillance method is universally superior. Healthcare facilities must consider their unique resources, patient populations, and infection control priorities.
Linking Detection to Consequences
A systematic review and meta-analysis was designed to estimate attributable mortality, length of stay, and healthcare costs associated with healthcare-acquired bloodstream infections in children and neonates. A 2025 study examined the epidemiological and clinical characteristics of infections in children hospitalized during the first quarters of 2021–2024, reflecting how the COVID-19 pandemic transformed the childhood-infection landscape. A 2026 scoping review maps prevention strategies, evidence, and research gaps for hospital-acquired infections in pediatric patients.
Toward More Adaptive Surveillance
Future surveillance may need to combine routine reporting with approaches that better capture under-reported infections and differences among pediatric patients. Research priorities are likely to include clearer comparisons across hospitals, age groups, and infection types. Any new method should be evaluated not only for detection, but also for whether it supports timely prevention and improves outcomes.
Inequity and Infection Risk
A 2025 review reports that infectious diseases remained the leading cause of death among children ages 1–59 months in 2023, when UNICEF reported 4.8 million deaths globally among children younger than five. APIC created a task force in 2021 to examine health inequity and disparities in infection prevention and control. Infection-prevention professionals can use this work to identify differences in infection outcomes, assess how health-related social needs affect infection risks, and advocate for policies addressing inequities.
Why Measurement Matters
For children and families, hospital infection surveillance matters because missed or delayed recognition can affect the course of care. The most useful approach is likely one that translates reliable detection into prevention, clearer communication, and safer treatment. Its real-world value should therefore be judged by whether it helps reduce avoidable harm while accounting for the different needs of pediatric patients.
For resource-limited settings, combining laboratory surveillance with antimicrobial prescription tracking offers a practical and effective approach. Regular PPSs can supplement these methods to provide a broader view of HAI prevalence.
Ultimately, the most successful HAI surveillance strategy is one that is tailored to the specific context of the healthcare facility, continuously monitored and adapted to improve its effectiveness over time, ultimately protecting the most vulnerable patient populations.
