lev-os Managing Newborn Assessments
Structures the systematic evaluation of a newborn using APGAR scoring, Ballard gestational-age assessment, initial physical examination, and mandated metabolic/hearing screening. Produces a complete birth assessment record suitable for nursery documentation and discharge planning.
Why This Skill Exists
Newborn assessments follow a time-critical sequence: APGAR at 1 and 5 minutes, gestational age within the first hours of life, comprehensive physical exam within 24 hours, and state-mandated screening before discharge. Missed findings at birth — cardiac murmurs, hip instability, undescended testes, metabolic disease — cascade into delayed diagnoses. This skill enforces the AAP-recommended framework so every newborn receives a standardized, auditable evaluation.
Checkpoint A — Intake Verification
Before beginning the assessment, confirm the following are available and complete:
Required Intake Questions
- What is the maternal obstetric history (G/P, GBS status, maternal labs, prenatal complications)?
- What was the mode of delivery (SVD, operative vaginal, cesarean) and any intrapartum events?
- What resuscitation steps, if any, were performed in the delivery room?
- What is the infant's birth weight, length, and head circumference?
- Has cord blood been collected for blood type and direct Coombs if indicated?
- Are maternal hepatitis B, HIV, RPR/VDRL, rubella, and blood type results available?
Required Documents
- Maternal prenatal record with lab results
- Labor and delivery summary including intrapartum fetal monitoring
- Delivery room resuscitation record (NRP documentation if applicable)
- Birth weight, length, and head circumference measurements
- Cord blood lab results (if obtained)
If any maternal lab results are unavailable, flag with [VERIFY] and escalate to attending before discharge planning proceeds.
Step 1 — APGAR Scoring (1 and 5 Minutes)
Score each of the five APGAR components at 1 minute and 5 minutes of life:
| Component | 0 | 1 | 2 |
|---|---|---|---|
| Appearance (color) | Blue/pale all over | Acrocyanosis (blue extremities, pink body) | Completely pink |
| Pulse (heart rate) | Absent | < 100 bpm | >= 100 bpm |
| Grimace (reflex irritability) | No response | Grimace only | Cry, cough, or sneeze |
| Activity (muscle tone) | Limp | Some flexion | Active motion |
| Respiration | Absent | Slow, irregular, weak cry | Good cry |
Scoring rules
- Record 1-minute score to assess transition status.
- Record 5-minute score to evaluate response to any intervention.
- If 5-minute score is < 7, continue scoring at 10, 15, and 20 minutes per NRP guidelines.
- APGAR does not guide resuscitation decisions — resuscitation follows NRP algorithm independently.
- Document who assigned the score and their role.
Step 2 — Gestational Age Assessment (New Ballard Score)
Perform the New Ballard Score within the first 12-24 hours of life:
Neuromuscular Maturity (6 criteria)
- Posture, square window (wrist), arm recoil, popliteal angle, scarf sign, heel to ear
Physical Maturity (7 criteria)
- Skin, lanugo, plantar surface, breast, eye/ear, genitalia (male or female)
Interpretation
- Total score range: -10 to 50, corresponding to 20-44 weeks gestation
- Compare Ballard-estimated GA to obstetric dating (LMP, early ultrasound)
- Discrepancy > 2 weeks between Ballard and obstetric dates warrants documentation and attending review
- Classify: SGA (< 10th percentile), AGA (10th-90th), LGA (> 90th) using Fenton or Olsen growth curves for preterm, WHO for term
Step 3 — Comprehensive Newborn Physical Examination
Perform the systematic head-to-toe exam within 24 hours of birth. Document each system:
Head/Fontanelles
- Anterior fontanelle size (normal: 1-4 cm diamond), posterior fontanelle (normal: < 1 cm, may be closed)
- Molding, caput succedaneum vs. cephalohematoma (crosses vs. does not cross suture lines)
- Subgaleal hemorrhage screen: boggy diffuse swelling crossing sutures — emergent if present
Eyes
- Red reflex bilaterally (absent = refer ophthalmology urgently for retinoblastoma, cataract rule-out)
- Conjunctival discharge, pupil symmetry
Cardiac
- Precordial activity, heart rate, rhythm
- Murmur present? If yes: timing, grade, location, radiation
- Pre- and post-ductal pulse oximetry per CCHD screening protocol (see Step 5)
- Four-extremity blood pressures if coarctation suspected
Hips
- Ortolani maneuver (reduction of a dislocated hip) and Barlow maneuver (provocation of dislocation)
- Document: stable, clicky (benign ligamentous), subluxable, dislocatable, or irreducible
- Risk factors for DDH: breech presentation, family history, female sex, oligohydramnios
Genitalia
- Male: testicular descent (bilateral? unilateral?), hypospadias, hydrocele
- Female: normal labia, vaginal patency, clitoral size
- Ambiguous genitalia: do NOT assign sex; emergent endocrine consult
Neurological
- Tone: resting posture, pull-to-sit head lag
- Primitive reflexes: Moro, palmar/plantar grasp, rooting, sucking, stepping
- Alertness and cry quality
Step 4 — Weight Classification and Growth Plotting
- Plot birth weight, length, and head circumference on appropriate growth chart:
- WHO growth standards for term infants (≥ 37 weeks)
- Fenton preterm growth chart for < 37 weeks
- Calculate weight-for-gestational-age percentile
- SGA < 10th percentile — screen for hypoglycemia per AAP protocol (glucose < 25 mg/dL in first 4 hours, < 35 mg/dL at 4-24 hours triggers intervention)
- LGA > 90th percentile — screen for hypoglycemia, assess for infant of diabetic mother (IDM) complications
- Macrosomia (> 4000g term): evaluate for birth trauma (clavicle fracture, brachial plexus injury)
Step 5 — Mandated Newborn Screening
Critical Congenital Heart Disease (CCHD) Screening
- Pulse oximetry on right hand (preductal) AND either foot (postductal) after 24 hours of age or before discharge
- Pass: both readings ≥ 95% AND difference ≤ 3%
- Fail: any reading < 90% — immediate echocardiogram
- Repeat: any reading 90-94% OR difference > 3% — rescreen in 1 hour, up to 3 attempts
Metabolic Newborn Screen (state-specific panel)
- Collect after 24 hours of age and adequate protein feeding
- Core conditions (ACMG-recommended): PKU, congenital hypothyroidism, galactosemia, sickle cell disease, CF, CAH, biotinidase deficiency, MCAD, and others per state mandate
- Document specimen collection time, feeding status, and any transfusions (which can affect results)
Hearing Screen
- OAE (otoacoustic emissions) or ABR (auditory brainstem response) before discharge
- Refer failures for diagnostic ABR by 3 months of age per JCIH guidelines
- Risk factors for hearing loss: NICU stay > 5 days, family history, ototoxic medications, hyperbilirubinemia requiring exchange transfusion, CMV
Step 6 — Risk Factor Documentation and Discharge Readiness
Document the following risk assessments before discharge:
- Hyperbilirubinemia risk: pre-discharge bilirubin level plotted on Bhutani nomogram; assign risk zone (low, low-intermediate, high-intermediate, high)
- Feeding adequacy: documented latch assessment (if breastfeeding), stool and urine output, percent weight loss from birth (> 7% by day 3 triggers lactation evaluation)
- Infection risk: GBS status, duration of rupture of membranes, maternal fever, and antibiotic administration per neonatal early-onset sepsis calculator
- Social risk: safe sleep environment confirmed, car seat available, follow-up appointment within 48 hours of discharge per AAP guidelines
Checkpoint B — Assessment Review
Before finalizing the newborn assessment record:
- APGAR scores recorded at 1 and 5 minutes (and extended intervals if < 7 at 5 minutes)
- Gestational age assessment completed with SGA/AGA/LGA classification
- Complete physical exam documented with all systems addressed
- Growth parameters plotted on appropriate charts
- CCHD pulse oximetry screening result documented with pass/fail/refer
- Metabolic newborn screen specimen collected with time and feeding status noted

- Pre-discharge bilirubin plotted on Bhutani nomogram with risk zone assigned
- Feeding assessment documented with weight loss percentage calculated
- Follow-up appointment scheduled within 48 hours of discharge
- All [VERIFY] flags resolved or escalated to attending

Guidelines
- Follow AAP "Guidelines for Perinatal Care" (8th edition) for examination timing and content
- Use NRP (Neonatal Resuscitation Program) 8th edition for delivery room assessment protocols
- Apply the New Ballard Score per Ballard et al. for gestational age assessment
- Follow AAP 2022 hyperbilirubinemia clinical practice guideline for bilirubin risk stratification
- Apply ACMG Recommended Uniform Screening Panel for metabolic newborn screen
- Follow JCIH (Joint Committee on Infant Hearing) 2019 position statement for hearing screening
- Never assign sex when genitalia are ambiguous — immediate endocrine and genetics consultation
- All findings should be documented using precise anatomical terminology, not shorthand
- Escalate to attending physician for any unexpected finding, abnormal screening, or maternal concern
- This skill produces documentation for clinical use; it does not replace clinical judgment
