Given these concerns, further analyses of known cases of https://www.beaxy.com/ is required to determine what proportion would be initially missed or GMT result in delayed treatment. No method for predicting EOS is perfect, and there is no substitute for clinical monitoring, since there will almost inevitably be some babies without risk factors for infection who nevertheless go onto to become septic. Effective evaluation will need approximately 100 cases of EOS to have occurred, a threshold not yet reached in the available literature. Difference in microbiology and in healthcare practices between the UK and the USA are significant in this context. When the EOS calculation is low risk, the calculator recommends “routine vitals”.
When blood culture results are known, i.e. in retrospective studies, it is possible that the clinical condition of the baby at birth may be recorded differently in the light of this, introducing bias. This is a potential issue for Joshi 2019, Shakib 2015, Money 2017 and Carola 2018 which evaluated the calculator retrospectively . Kuzniewicz 2017, Dhudasia 2018, Strunk 2018, Sharma 2019 and Arora 2019 had retrospective comparison groups which could also have been affected.

The interpretation of such findings is not clearly described and may be a source of potential bias. Determining which babies should receive antibiotics for potential early onset sepsis is challenging. We performed a meta-analysis quantifying how many EOS cases might be ‘missed’ using the Kaiser Permanente electronic calculator, compared with National Institute for Health and Care Excellence guidelines. Potential benefit from the implementation of the Kaiser Permanente neonatal early-onset sepsis calculator on clinical management of neonates with presumed sepsis.
“Approximately six months after standardizing antibiotic treatment course durations, we knew if we adopted the SRC it would continue to improve consistency of practice within the pediatric groups. The absolute eosinophil count is a test similar to the total blood count, where the target is the number of eosinophil cells in a given blood sample. The state of eosinophil count elevation over 0.45 × 10³ cells/μL is called eosinophilia and is linked to allergic reactions and parasitic infections. Therefore, we do not have data related to out-of-system hospital readmissions.

We used the CDC national incidence of EOS (0.5 per 1,000 live births). The quality improvement team was composed of physicians in charge of the newborn nursery, NICU attendings, a pharmacist, NICU nursing leadership, and a medical student. Treat patients with pre-existing helminth infections before initiating therapy with NUCALA. If patients become infected while receiving NUCALA and do not respond to anti-helminth treatment, discontinue NUCALA until infection resolves.
The case of the eos calc states that it was manufactured in Switzerland so at least some of it was made there. The EOS calculator was made by the EOS-Genossenschaft für Fabrikation und Vertrieb von Rechenmaschinen, based in Zürich at Albisstraße 2. The EOS was virtually identical to the Hannovera CK, except that the case has an EOS logo. As with the CK, two carriage shifting mechanisms were available, a simple crank or a more complicated mechanism with a knob.
If continued despite a negative culture, treatment was continued for 7 days. Safety is of critical importance and risk of missing cases of EOS is a major concern in the evaluation of management strategies for newborns at risk for or with suspected EOS. Risk management strategies for EOS need to balance the risk of a missed case of EOS against the harm of unnecessary antibiotics on a population level.5,15 Even well-appearing newborns with no risk factors can develop EOS. In contrast, the EOS calculator provides an individual EOS risk estimate for each newborn, and our review summarizes the current real-world evidence on this outcome in clinical practice.
When empiric antibiotics are recommended by the SRC, draw a blood culture, and utilize ampicillin and gentamicin. This was a single-center retrospective study from 1st January 2018 to 31st December 2018 conducted in the Division of Neonatology at Santa Chiara Hospital . The parents of all subjects signed a written consent form and the study was approved by the ethics committee of the Meyer Children’s Hospital of Florence. Based on our local guidelines, neonates born at ≥34 weeks’ GA are divided into three categories as shown in Table2, and managed as shown in Table3.
- Pediatric residents, neonatal fellows, and attendings received education on the use of the EOS calculator.
- Berardi et al. showed that the universal SPE approach could produce a sharp reduction in laboratory exams and antibiotic treatments without a consequent increase in EOS .
- 1 case in each epoch, both were clinically unwell requiring admission to the neonatal unit.
- In contrast, only 37% of infants requiring NICU admission for sepsis evaluation and treatment were breastfeeding at discharge.
Total white blood cell count with its subcomponents and platelet count have also shown a poor predictive accuracy, and the specificity and selectivity of genetic biomarkers are yet to be fully evaluated . Protein biomarkers demonstrate high specificity and sensitivity and include C-reactive protein and Procalcitonin , which are the most commonly used protein biomarkers for the diagnosis of sepsis and monitoring of antibiotic therapy . Both CRP and PCT have a physiologic increase over the first 24–48 h of life; baseline concentrations of both markers are mainly affected by birth weight and gestational age . On these basis, different attempts have been done to establish the appropriate cut-off values of both PCT and CRP . Umbilical blood PCT and CRP have also been tested for EOS diagnosis; cut-off values were different among studies (0.5–2 ng/ml for PCT and 1–10 mg/l for CRP) .
How do I calculate the absolute eosinophil count?
The overall risk of bias was judged as high for 9 studies, low for 2 studies, and unclear for 2 studies . We graded the overall quality of evidence for the primary outcome of reduction in use of empirical antibiotics as moderate, owing to the inclusion of very large observational studies that had large effect sizes and the consistency of results. We graded the quality of evidence regarding safety of use of the EOS calculator as very low, mainly owing to the small number of events across all studies. There was a minimum of 14 , and a maximum of 22 , cases of EOS where the calculator did not recommend empirical antibiotics, i.e. they would have been/were initially ‘missed’ compared to BNB NICE guidelines, see supplementary table S3.

Getting started with EOS calculator
Proportion of cases missed by the calculator , all studies − worst case scenario. Proportion of cases missed by the calculator , all studies − best case scenario. See and Supplementary Table S1 – data extracted from articles, excluding contaminants. For completion, we performed two meta-analyses, a ‘worst case’ scenario where uncertain cases were recorded as a ‘miss’, and a ‘best case’ scenario where the uncertain cases were treated as if they were not missed. 187 infants were excluded because their treatment was decided by NICU clinicians who had not received the quality improvement training.
The next set of AAP guidelines on EOS should be out before Christmas. Currently it’s not included. If anything I’m predicting the guidelines may recommend less evaluations in general. A lot of people are getting on board with ‘sepsis risk calculators’ (Kaiser calc).

Our findings of reduced economic costs in term newborns align with a recent theoretical study by Gong et al., predicting significant costs reductions due to EOS calculator implementation . For acute medical care, the model by Gong et al. predicted estimated cost savings of 1930$, equaling a relative reduction of 52%. Mean cost reduction for term newborns in our study was significantly smaller, at 207€ or a relative reduction of 9%. First, Gong et al. used a fictitious relative reduction of 67% in empiric antibiotic treatment by implementation of the EOS calculator, which is significantly above real-world evidence in the literature .
CM, TC, SE, MM and CA analyzed and interpreted the patient data and critically revised the manuscript. As our rate of EOS workup and antibiotic treatment was higher than the data reported in the literature, we decided to revise our protocol according to recent guidelines. Risk factors for early-onset neonatal sepsis include maternal, perinatal, and neonatal factors . Well-known organisms causing early-onset neonatal sepsis are typically colonizers of the maternal genitourinary tract. These can include Group B Streptococcus and Escherichia coli, which play a major role in the etiology of this disease .

Development and implementation of an early-onset sepsis calculator to guide antibiotic management in late preterm and term neonates. EOS calculator has been proven to be an effective tool for treatment decision-making of neonatal EOS, however we have shown a further decrease in antibiotics administration through a continuous evidence-based update of local guidelines. In P1, according to the in-use protocol, we performed laboratory tests and administered antibiotic therapy to the newborns subsequently diagnosed with EOS because of risk factors such as prematurity and PROM. The primary outcome measure was the monthly rate of NICU admissions for sepsis evaluation/treatment in infants older than 35 weeks gestation born to mothers with chorioamnionitis. Secondary outcomes included monthly rates of sepsis amongst at-risk infants and breastfeeding rates at discharge for infants admitted to the NICU as compared with those who remained in the newborn nursery. A combined strategy, including the neonatal EOS calculator and the universal SPE approach, allowed our institution to overcome the limitations of the two single approaches.
The drastic decrease in the treatment rate was likely mainly due to the introduction of the EOS calculator, but the extensive use of the SPE form in the entire population has resulted in a further reduction. In particular, when applying the serial physical examination, great importance was placed on skin discoloration and circulatory signs, whereas an attitude of prudent clinical waiting for early mild respiratory symptoms was allowed. One of the primary practice changes that were implemented as a result of this quality improvement initiative was the delay in newborn bathing until 24 hours of life in the newborn nursery. Before this study, nursing staff bathed newborns around 4 hours of life upon admission to the postpartum floor.
Pediatric residents, neonatal fellows, and attendings received education on the use of the EOS calculator. These caregivers were responsible for using the online calculator following the delivery of an identified at-risk infant and examining the neonate to determine the need for laboratory work and/or antibiotics. The guidelines were posted in the nursery and made into laminated cards for clinicians’ badges. Infants deemed ill at birth were immediately transferred to the NICU for laboratory evaluation and antibiotic administration. Historically, at MacDonald Women’s and Rainbow Babies and Children’s Hospital, infants 35 weeks and older’ gestation born to mothers diagnosed clinically with chorioamnionitis were admitted to the NICU regardless of clinical appearance. In 2013 and 2014, approximately 5% of women delivering at 35 weeks and older’ gestation had a diagnosis of chorioamnionitis.
This study evaluates the sensitivity of the calculator compared to NICE guidelines. We have not made any assessment of its specificity, or its safety when implemented with a whole-nursery system of newborn care. This study does not make a comprehensive assessment of the overall performance of the calculator, rather we have assessed its immediate ability to accurately detect babies who go on to have positive blood cultures. According to most early-onset sepsis management guidelines, approximately 10% of the total neonatal population are exposed to antibiotics in the first postnatal days with subsequent increase of neonatal and pediatric comorbidities. A review of literature demonstrates the effectiveness of EOS calculator in reducing antibiotic overtreatment and NICU admission among neonates ≥34 weeks’ gestational age ; however, some missed cases of culture-positive EOS have also been described.
