Management is medically necessary at the indicated level of care.

Culture-negative infant requiring continued antibiotics
- Infant has negative cultures and requires antibiotics beyond 48 hours>48 hours
- Antibiotics are the only intervention necessitating continued stay
- Outpatient antibiotics are inappropriate or unmanageable
Symptomatic infant
- Infant has signs of neonatal sepsis, such as hypotonia, lethargy, poor oral feeding, tachycardia, bradycardia, grunting, nasal flaring, or cyanosis

Discharge criteria

Discharge, with or without home antibiotics, requires all applicable criteria to be met.

Infant is clinically stable
The home situation is assessed and deemed adequate
Parent or caretaker agrees with the plan of care
Provider follow-up is scheduled within 48 hours of dischargeWithin 48 hours of discharge
Home antibiotics
- A contractual agreement of care is signed with a home infusion company experienced in neonatal IV therapy or short-term intramuscular therapy

Newborn risk assessment and initial treatment

Newborn identification and treatment are based on gestational age, birth circumstances, clinical condition, and risk assessment.

Newborn EOS assessment and treatment

Infants born at ≥35 weeks: Manage according to risk as determined by categorical risk assessment, clinical condition, or multivariate risk assessment≥35 weeks
Higher-risk preterm infants
- Infant is born at ≤34 weeks gestation≤34 weeks
- Birth circumstances associated with highest EOS risk
  - Cervical insufficiency

Treatment discontinuation and transition

Treatment and monitoring should follow the infant's clinical condition and culture results.

General treatment considerations

For a term infant at risk of early-onset sepsis, therapy includes antimicrobial agents active against Group B streptococcus, including IV ampicillin and gentamicin, as well as organisms such as E. coli
When blood cultures are sterile, discontinue antibiotic therapy by 36 to 48 hours of incubation unless there is clear evidence of site-specific infectionBy 36 to 48 hours of incubation
A stable infant at 35 weeks gestational age or older who is treated for sepsis is discharged the same day antibiotics are discontinued≥35 weeks
Consider cerebrospinal fluid analysis in a clinically ill preterm infant with high suspicion for Group B streptococcal early-onset disease unless lumbar puncture would compromise the infant's clinical condition

Discharge Documentation

Document that the infant meets applicable discharge criteria, including clinical stability, an adequate home situation, caregiver agreement with the plan of care, and follow-up scheduled within 48 hours of discharge. When discharge includes home antibiotics, document the required home-treatment arrangements before discharge.

Clinical stability: Record that the member/enrollee is clinically stable.
Home situation: Assess and document that the home situation is adequate.
Caregiver agreement: Document parent or caretaker agreement with the plan of care.
Home antibiotics, if applicable: Document a signed contractual agreement with a home infusion company experienced in neonatal IV therapy or short-term intramuscular therapy; secure IV access if selected; and contact information for the responsible physician and a backup facility, such as a NICU or community hospital, provided to the family and home care agency before discharge.
Follow-up: Schedule provider follow-up within 48 hours after discharge.

Documentation Required

Neonatal Sepsis Context

Neonatal sepsis remains a prevalent cause of neonatal morbidity and mortality. Although increased use of intrapartum antibiotics has reduced the frequency of early-onset neonatal sepsis, Group B streptococcus (GBS) remains the leading cause of early-onset disease and a major cause of late-onset sepsis. More than half of GBS cases occur in infants born to individuals with negative GBS cultures, so vigilance for signs of sepsis is needed in all newborns.

Timely, comprehensive assessment and treatment, including risk-based evaluation, appropriate antimicrobial therapy, nursery-level management, and discharge planning, are essential to reduce neonatal morbidity and mortality.

Contact information for the responsible physician and backup healthcare facility is provided to the family and home care agency before discharge

Premature rupture of membranes

Intraamniotic infection

Acute and otherwise unexplained nonreassuring fetal status

Lower-risk preterm infants

Infant is born at ≤34 weeks gestation≤34 weeks
All lower-risk birth criteria
- Maternal and/or fetal indication for preterm birth, such as maternal preeclampsia or other noninfectious medical illness, placental insufficiency, or fetal growth restriction
- Birth by cesarean delivery
- No labor, no attempts to induce labor, and no rupture of membranes before delivery

The infant is receiving antibiotics pending blood culture results or is being treated for positive blood cultures.

Post-discharge provider follow-up

Follow-up deadlineWithin 48 hours of discharge

Discharge requirementProvider follow-up must be scheduled before discharge.

Discharge contextThe requirement applies to discharge with or without home antibiotics.

Antibiotic discontinuation with sterile cultures

Discontinuation windowBy 36 to 48 hours of incubation

Culture statusBlood cultures are sterile.

ExceptionContinue antibiotics if there is clear evidence of site-specific infection.

Prolonged rupture of membranes

Term ROM thresholdROM ≥18 hours at term

Clinical contextThe threshold is used when screening results are not available at the time of labor and delivery.

Related actionIntrapartum antibiotics should be given when this substantial risk is present.

GBS bacteriuria

GBS bacteriuria threshold>10^5 CFU/mL

MeasurementColony-forming units per milliliter (CFU/mL)

Treatment contextUnless symptomatic GBS UTI is present or GBS bacteriuria exceeds this threshold, antimicrobial agents should not be used before the intrapartum period to eradicate GBS genitorectal colonization.

Level-of-Care Support

Support the requested nursery level with documentation of the infant’s clinical findings, temperature, culture status, and antibiotic treatment status. Once culture and sensitivity results are known and therapy is established, document transition to a lower level of care when the infant is medically stable and no other indication requires the current level; consider transitional care when IV antibiotics cannot be safely managed at home.

Signs of sepsis: Document applicable symptoms, including hypotonia, lethargy, poor oral feeding, tachycardia, bradycardia, grunting, nasal flaring, or cyanosis.
Temperature: Record temperature of ≥ 100.4 °F or ≤ 96.8 °F (≥ 38.0 °C or ≤ 36.0 °C) when supporting level III care.
Culture and antibiotic status: Document whether cultures are pending or positive, whether the infant is receiving 48 hours of antibiotics pending blood culture results, and whether positive cultures are being treated.
Level I/II support: Well-appearing infants receiving 48 hours of antibiotics pending cultures may be supported at level I or II; asymptomatic infants on this regimen for ≤ 2 days are appropriate for level II.
Level III support: Symptomatic infants require documentation of all applicable criteria—sepsis signs, qualifying temperature, and 48 hours of antibiotics pending cultures or treatment of positive cultures.
Subsequent-day care: Infants with negative cultures requiring antibiotics beyond 48 hours may transition to transitional care or level I when antibiotics are the only continued-stay intervention and outpatient treatment is inappropriate or unmanageable. Asymptomatic infants with positive cultures and no other indications are appropriate for transitional care.
Home treatment feasibility: Document whether IV antibiotics can be safely administered at home or with home health care; transitional care should be considered when secure home administration is not feasible.
