Impact of early-onset sepsis guidelines on breastfeeding

Neonatal bacterial sepsis

Neonatal sepsis remains one of the key challenges of neonatal medicine, and together with preterm birth, causes almost 50% of all deaths globally for children younger than 5 years. Compared with advances achieved for other serious neonatal and early childhood conditions globally, progress in reducing neonatal sepsis has been much slower, especially in low-resource settings that have the highest burden of neonatal sepsis morbidity and mortality. By contrast to sepsis in older patients, there is no universally accepted neonatal sepsis definition. This poses substantial challenges in clinical practice, research, and health-care management, and has direct practical implications, such as diagnostic inconsistency, heterogeneous data collection and surveillance, and inappropriate treatment, health-resource allocation, and education. As the clinical manifestation of neonatal sepsis is frequently non-specific and the current diagnostic standard blood culture has performance limitations, new improved diagnostic techniques are required to guide appropriate and warranted antimicrobial treatment. Although antimicrobial therapy and supportive care continue as principal components of neonatal sepsis therapy, refining basic neonatal care to prevent sepsis through education and quality improvement initiatives remains paramount.

Quality Improvement Through Nurse-initiated Kaiser Sepsis Calculator at a County Hospital

BACKGROUND AND OBJECTIVES

Suspected early onset sepsis drives most antibiotic use in the newborn nursery. The Kaiser Sepsis Calculator (KSC) is a validated tool that safely decreases laboratory evaluation and antibiotic administration in infants aged ≥34 weeks. Our quality improvement aim was a nurse-initiated, KSC-based program to decrease blood cultures (BCx) and complete blood counts (CBC) by 10% from March 2021 to October 2021 among chorioamnionitis-exposed infants born ≥35 weeks' gestation. A secondary aim was to decrease antibiotic administration by 10%.

METHODS

The KSC was implemented for infants at University Health, a county hospital affiliate of the University of Texas Health Science Center San Antonio, with a level I nursery and level IV NICU. The multidisciplinary project included pediatric hospitalists, neonatologists, family practitioners, maternal-fetal medicine physicians, fellows, residents, and nurses. All infants born 6 months before (August 2020-January 2021) and 7 months after protocol implementation (March 2021-September 2021) were analyzed.

RESULTS

A total of 53 chorioamnionitis-exposed infants were included from the preintervention period and 51 from the postintervention period. CBC utilization decreased from 96% to 27%, BCx utilization decreased from 98% to 37%, and antibiotic utilization fell from 25% to 16%. In no cases were antibiotics prescribed against the KSC, and to our knowledge, no early onset sepsis diagnoses or infection-related hospital readmissions were missed.

CONCLUSIONS

The multidisciplinary implementation of the KSC led to a reduction in testing, exceeding our initial goal. A nurse-initiated protocol reduced BCx, CBC, and antibiotic utilization among chorioamnionitis-exposed infants.

Results of a strategy based on clinical observation of newborns at risk of early-onset neonatal sepsis

BACKGROUND

Serial clinical observation of asymptomatic newborns at risk of early-onset sepsis is an alternative option for which there is limited scientific evidence.

AIMS

To evaluate the rate of protocol compliance, the impact on blood tests, percentage of hospitalizations and subsequent procedures, and course of diagnosed early-onset sepsis cases of a protocol based on serial clinical observation.

METHODS

Retrospective observational study comparing an 18-month period under this protocol against a previous protocol based on laboratory tests.

SUBJECTS

6895 asymptomatic newborns with over 35 weeks of gestation.

OUTCOME MEASURES

number of evaluations performed on each subject at risk, percentage of patients undergoing blood draws and hospitalization rates.

RESULTS

Some of the evaluations included in the protocol were omitted in 51.6 % of the newborns undergoing the physical examinations. The implementation of this new approach was associated with a decrease in the percentage of patients undergoing blood draws from 16.8 % to 0.7 % (p < 0.001) with no differences in the progression of the five cases of sepsis studied in each period. The serial clinical observation protocol was associated with a significant increase in hospitalizations for suspected infection, although with no difference in the rate of lumbar punctures performed or antibiotic treatments administered.

CONCLUSION

Compliance with the serial clinical observation protocol can be difficult. This approach often detects newborns with abnormal clinical data that are not explained by early-onset sepsis. Clinical observation is a safe option that minimizes the rate of blood draws.
