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

[ ] 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

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
