Jaundice is extremely common in newborns.

Most cases are temporary and resolve without causing harm. But when bilirubin rises to dangerously high levels and is not recognized or treated appropriately, bilirubin can injure the developing brain.

That neurological injury is known as bilirubin encephalopathy. Permanent bilirubin-related brain injury is commonly called kernicterus.

For Kentucky parents whose baby experienced severe hyperbilirubinemia, hospitalization, exchange transfusion, neurological symptoms, hearing loss, cerebral palsy, or another serious outcome, the questions often become:

• Was my baby’s bilirubin measured before discharge?
• Were known risk factors recognized?
• Was follow-up scheduled soon enough?
• Were rising bilirubin results acted on?
• Should phototherapy have started earlier?
• Should care have been escalated or the baby transferred?
• Was hemolysis or G6PD deficiency considered?
• Could the neurological injury have been prevented?

A serious outcome does not automatically mean that a doctor, pediatrician, nurse, or hospital committed malpractice.

A Kentucky kernicterus claim generally requires detailed review of the baby’s bilirubin levels, age in hours, gestational age, risk factors, feeding and weight history, treatment thresholds, follow-up plan, and the timing of medical decisions.

What Is Newborn Jaundice?

Jaundice is the yellow appearance of a newborn’s skin or eyes caused by an increased level of bilirubin in the blood.

Bilirubin is produced when red blood cells are broken down.

During pregnancy, the placenta helps remove bilirubin. After birth, the newborn’s liver takes over that job.

Because newborn liver function is still developing and newborns naturally turn over large numbers of red blood cells, bilirubin commonly rises during the first several days of life.

The American Academy of Pediatrics states that more than 80% of newborn infants develop some degree of jaundice.

For most babies, this does not cause permanent harm.

The concern is severe unconjugated hyperbilirubinemia, particularly when bilirubin reaches levels associated with neurological toxicity.

What Is Kernicterus?

Kernicterus is permanent neurological injury resulting from bilirubin toxicity in the brain.

The American Academy of Pediatrics describes kernicterus as a permanent disabling neurological condition that may involve:

• Choreoathetoid or dyskinetic cerebral palsy
• Sensorineural hearing loss
• Auditory neuropathy
• Abnormal upward gaze
• Dental enamel abnormalities
• Characteristic brain MRI findings

The exact effects vary from child to child.

Kernicterus is rare, but it is particularly important because severe bilirubin-related neurological injury is often preventable through appropriate screening, monitoring, follow-up, and treatment.

Acute Bilirubin Encephalopathy vs. Kernicterus

These terms are related but are not identical.

Acute Bilirubin Encephalopathy

Acute bilirubin encephalopathy describes neurological dysfunction occurring while bilirubin toxicity is actively affecting the brain.

Potential findings can include:

• Poor feeding or weak sucking
• Marked lethargy
• Abnormal muscle tone
• Irritability
• High-pitched cry
• Arching of the neck or back
• Abnormal movements
• Seizures in severe cases

The AAP’s treatment guideline identifies findings such as hypertonia, arching, retrocollis, opisthotonos, fever, and high-pitched cry as signs associated with intermediate or advanced acute bilirubin encephalopathy.

Kernicterus

Kernicterus generally refers to the chronic, permanent neurological effects of bilirubin toxicity.

A baby can have severe hyperbilirubinemia without developing kernicterus.

That is one reason rapid recognition and treatment matter.

When Should a Newborn’s Bilirubin Be Checked?

The American Academy of Pediatrics significantly updated its hyperbilirubinemia guidance in 2022.

For newborns 35 weeks’ gestation or older, the AAP recommends that every baby have at least one objective bilirubin measurement before discharge.

The measurement should generally be obtained:

• Between 24 and 48 hours after birth, or
• Before discharge, if the baby leaves the birth hospital earlier

The measurement may initially be obtained through:

• Transcutaneous bilirubin (TcB) testing, using a device placed against the skin, or
• Total serum bilirubin (TSB) testing, using a blood sample

The AAP identifies TSB as the definitive test for decisions about:

• Starting phototherapy
• Escalating care
• Exchange transfusion

Visual assessment of skin color alone is not an adequate substitute for objective bilirubin measurement.

The Old “Bilirubin Nomogram” vs. the Current AAP Approach

Parents may hear clinicians, lawyers, or older online resources refer to a bilirubin nomogram.

That terminology can be confusing because the AAP changed its follow-up framework in 2022.

Older guidance commonly used the Bhutani risk-zone nomogram, which divided predischarge bilirubin measurements into percentile-based risk zones.

The current AAP guideline does not use those old risk zones to determine routine post-discharge follow-up.

Instead, clinicians consider the difference between:

1. The baby’s measured bilirubin, and
2. The applicable phototherapy threshold for that baby’s age in hours, gestational age, and neurotoxicity risk factors.

The closer the bilirubin is to the phototherapy threshold, the sooner follow-up testing may be needed.

The AAP still uses age- and gestational-age-specific graphs and thresholds for treatment decisions, so the word “nomogram” may still appear informally. But the old Bhutani risk-zone method should not be confused with the current follow-up framework.

Why the Baby’s Age in Hours Matters

A bilirubin value cannot be interpreted responsibly without knowing when it was measured.

For example, the meaning of a particular bilirubin concentration can be very different at:

• 18 hours
• 36 hours
• 72 hours
• Five days

The AAP treatment thresholds therefore depend on the infant’s postnatal age in hours, along with gestational age and neurotoxicity risk factors.

For a possible kernicterus case, every bilirubin result should be reviewed together with its exact:

• Date
• Time
• Baby’s age in hours
• Gestational age
• Treatment status

What Factors Increase the Risk of Significant Hyperbilirubinemia?

The AAP identifies several factors associated with a greater likelihood of developing significant hyperbilirubinemia.

They include:

• Lower gestational age
• Jaundice during the first 24 hours after birth
• Predischarge bilirubin close to the phototherapy threshold
• Known or suspected hemolysis
• Rapidly increasing bilirubin
• Phototherapy before discharge
• A parent or sibling who previously required phototherapy or exchange transfusion
• Family history or ancestry suggesting an inherited red-blood-cell disorder such as G6PD deficiency
• Exclusive breastfeeding with inadequate intake
• Scalp hematoma or significant bruising
• Down syndrome
• A macrosomic infant of a diabetic mother

These factors do not mean a baby will develop kernicterus.

They can influence how closely the infant should be monitored.

Hyperbilirubinemia Risk Factors vs. Neurotoxicity Risk Factors

The AAP makes an important distinction.

Some factors increase the chance that the baby’s bilirubin will rise.

Other factors increase the chance that a given bilirubin concentration will cause neurological toxicity.

Recognized bilirubin neurotoxicity risk factors include:

• Gestational age under 38 weeks
• Serum albumin below 3.0 g/dL
• Isoimmune hemolytic disease
• G6PD deficiency or another hemolytic condition
• Sepsis
• Significant recent clinical instability

These factors can lower the bilirubin level at which treatment or escalation becomes appropriate.

That distinction can be critical when experts later reconstruct whether treatment decisions were reasonable.

Can a Cephalohematoma Increase the Risk of Severe Jaundice?

Yes.

The AAP specifically lists scalp hematoma or significant bruising as a risk factor for developing significant hyperbilirubinemia.

A cephalohematoma contains blood beneath the periosteum of a skull bone.

As that blood breaks down, additional bilirubin can be produced.

A cephalohematoma does not mean a baby will develop severe jaundice, but it can be one factor supporting closer monitoring.

For families whose child had both a cephalohematoma and severe hyperbilirubinemia, potentially important records include:

• Delivery records
• Documentation of scalp swelling or bruising
• Bilirubin measurements
• Feeding and weight records
• Discharge planning
• Follow-up testing

What Is Hemolytic Jaundice?

Hemolysis means red blood cells are breaking down more rapidly than normal.

Because red-cell breakdown produces bilirubin, hemolysis can cause bilirubin to rise quickly.

Possible causes include:

• ABO blood-group incompatibility
• Rh incompatibility
• Other immune-mediated hemolysis
• G6PD deficiency
• Other red-blood-cell disorders

A medical review may consider:

• Maternal blood type
• Maternal antibody screening
• Infant blood type
• Direct antiglobulin test (DAT/Coombs)
• Complete blood count
• Reticulocyte count
• Bilirubin rate of rise
• G6PD testing when clinically appropriate

A rapid increase in bilirubin can be important evidence of hemolysis.

Why G6PD Deficiency Matters

The AAP identifies glucose-6-phosphate dehydrogenase deficiency, or G6PD deficiency, as one of the most important causes of hazardous hyperbilirubinemia leading to kernicterus in the United States and worldwide.

G6PD deficiency is inherited.

Many affected babies do not have an obvious family history.

Depending on the situation, a potential kernicterus investigation may consider:

• Whether G6PD deficiency was suspected
• Family or genetic ancestry information
• Bilirubin trajectory
• Whether hemolysis appeared to be occurring
• Whether appropriate testing was considered
• Exposure to potential oxidative triggers
• Whether treatment was escalated appropriately

The existence of G6PD deficiency does not itself establish that any provider was negligent.

Feeding, Weight Loss, and Jaundice

Inadequate milk intake during the first days of life can contribute to significant hyperbilirubinemia.

The AAP uses the term “suboptimal intake hyperbilirubinemia” for this pathway.

Potentially important evidence can include:

• Breastfeeding frequency
• Latch assessments
• Lactation consultations
• Supplementation discussions
• Wet and dirty diapers
• Birth weight
• Discharge weight
• Percentage of weight loss
• Follow-up weight measurements
• Feeding instructions given to the family

The presence of breastfeeding does not itself cause malpractice or dangerous jaundice.

The issue is whether feeding adequacy, bilirubin, weight, and other risk factors were appropriately evaluated together.

How Severe Newborn Jaundice Is Treated

Treatment depends on the baby’s:

• Gestational age
• Age in hours
• Total serum bilirubin
• Bilirubin trend
• Neurotoxicity risk factors
• Clinical condition

The major treatment approaches include phototherapy and, in severe cases, exchange transfusion.

Phototherapy

Phototherapy uses specific wavelengths of light to change bilirubin into forms the baby’s body can eliminate more easily.

The AAP’s treatment thresholds are based on:

• Gestational age
• Age in hours
• Presence or absence of neurotoxicity risk factors

Phototherapy should therefore not be started or withheld based on a single universal bilirubin number.

The correct threshold varies from baby to baby.

Does Sunlight Treat Newborn Jaundice?

Parents should not substitute sunlight for prescribed medical treatment.

Current medical resources do not recommend placing a newborn in direct sunlight as a treatment for significant jaundice.

When treatment is medically indicated, phototherapy uses controlled equipment and defined treatment parameters.

What Is “Escalation of Care”?

The 2022 AAP guideline introduced a formal escalation-of-care threshold.

That threshold is 2 mg/dL below the applicable exchange transfusion threshold.

The AAP describes reaching the escalation-of-care threshold as a medical emergency.

For a baby requiring escalation of care, recommendations include:

• Emergent intensive phototherapy
• Intravenous hydration
• STAT laboratory testing
• Frequent total serum bilirubin measurement
• Neonatology involvement
• Transfer to a NICU capable of exchange transfusion when the current facility cannot provide it

The AAP recommends measuring TSB at least every two hours during the escalation-of-care period.

These details can become important in a case involving rapidly rising bilirubin.

When Is Exchange Transfusion Used?

An exchange transfusion removes portions of the baby’s blood and replaces them with compatible blood products to rapidly reduce bilirubin and address certain underlying blood-related problems.

The 2022 AAP guideline recommends urgent exchange transfusion when:

• The baby’s TSB is at or above the applicable exchange transfusion threshold, subject to ongoing reassessment while treatment is being prepared, or
• The infant shows signs of intermediate or advanced acute bilirubin encephalopathy

Exchange transfusion is a major neonatal procedure.

The fact that a baby ultimately required one does not by itself establish that earlier care was negligent.

Experts must review the entire bilirubin trajectory and clinical timeline.

When Severe Jaundice May Raise Questions About Medical Negligence

Not every severe jaundice case supports a malpractice claim.

Potential areas of investigation can include the following.

Failure to Obtain a Predischarge Bilirubin Measurement

The AAP recommends objective predischarge bilirubin measurement for newborns covered by its guideline.

A potential investigation may therefore examine:

• Whether a TcB or TSB measurement was obtained
• The baby’s age when it was obtained
• Whether the result was documented
• Whether appropriate follow-up was based on that result

Relying Only on Visual Assessment

Jaundice can be difficult to assess accurately from appearance alone.

This can be especially important across different skin tones.

The AAP recommends objective bilirubin screening rather than relying solely on visual estimation.

Failure to Recognize a Bilirubin Near the Treatment Threshold

Under current AAP guidance, follow-up after discharge is closely connected to the difference between the baby’s bilirubin and the phototherapy threshold.

A legal and medical review may therefore examine:

• The actual bilirubin result
• Applicable treatment threshold
• Gestational age
• Neurotoxicity risk factors
• How soon repeat testing was needed
• What follow-up was actually arranged

Inadequate Discharge or Follow-Up Planning

The AAP emphasizes having a concrete post-discharge plan.

Current guidance calls for the predischarge bilirubin level and important risk information to be communicated to the clinician responsible for follow-up.

Potential questions include:

• Was a follow-up appointment scheduled?
• When was it scheduled?
• Was repeat bilirubin testing ordered?
• Did the receiving pediatrician have the predischarge bilirubin result?
• Were parents given understandable jaundice instructions?
• Were warning signs explained?

Failure to Respond to a Rising Bilirubin

An investigation may examine:

• When each laboratory result became available
• Who received it
• Whether the result triggered a call or electronic alert
• When treatment was ordered
• When phototherapy actually began
• Whether additional laboratory testing was obtained
• Whether bilirubin continued rising despite treatment

Exact timestamps can be very important.

Failure to Recognize Hemolysis or Other Risk Factors

When the bilirubin rises rapidly or other findings suggest hemolysis, experts may evaluate whether appropriate testing and treatment were considered.

The analysis can include:

• DAT/Coombs testing
• Blood-group information
• Reticulocyte count
• Complete blood count
• G6PD testing
• Albumin
• Sepsis or clinical instability

Not every baby requires every test.

The question is whether the evaluation matched the baby’s actual presentation.

Failure to Escalate Care or Transfer

Once bilirubin reaches the AAP escalation-of-care threshold, the guideline treats the situation as a medical emergency.

A potential case may examine:

• When the threshold was reached
• When intensive phototherapy began
• Whether IV hydration was provided
• Frequency of repeat bilirubin measurements
• When neonatology became involved
• Whether transfer was required
• When transfer was requested and completed
• Whether exchange transfusion was available

What Records Matter in a Kernicterus Case?

A meaningful review requires more than the final hospital discharge summary.

Bilirubin Records

Request every:

• Transcutaneous bilirubin reading
• Total serum bilirubin result
• Direct or conjugated bilirubin result
• Date and time of collection
• Date and time the result became available
• Repeat bilirubin measurement

A chronological table of bilirubin values can become one of the most important tools in the investigation.

Treatment Threshold Documentation

Request any available:

• Phototherapy threshold calculation
• EHR bilirubin decision-support output
• Treatment graph
• Clinical decision note
• Escalation-of-care calculation
• Exchange-transfusion threshold documentation

Because the 2022 guideline bases decisions on gestational age, age in hours, and neurotoxicity risk factors, the threshold used can matter as much as the bilirubin number itself.

Phototherapy Records

Request:

• Phototherapy orders
• Start time
• Stop time
• Nursing flowsheets
• Type of phototherapy
• Interruptions in therapy
• Bilirubin results during treatment
• Rebound bilirubin testing
• Feeding and hydration documentation

Hemolysis and Blood-Group Records

Potentially important evidence includes:

• Maternal blood type
• Maternal antibody screen
• Newborn blood type
• DAT/Coombs result
• CBC
• Hemoglobin
• Hematocrit
• Reticulocyte count
• G6PD testing
• Albumin

Feeding and Weight Records

Save:

• Birth weight
• Daily weights
• Discharge weight
• Percentage weight loss
• Breastfeeding documentation
• Formula or expressed-milk supplementation
• Lactation notes
• Intake and output
• Wet diaper documentation
• Stool records

Delivery-Related Risk Factors

Request records documenting:

• Cephalohematoma
• Significant bruising
• Vacuum delivery
• Forceps delivery
• Other birth trauma

These findings may contribute additional bilirubin load.

Discharge Records

Potentially critical documents include:

• Discharge summary
• Written jaundice instructions
• Predischarge bilirubin result
• Follow-up appointment
• Repeat lab order
• Pediatrician handoff
• Telephone instructions
• Patient portal communications

Emergency Department and Readmission Records

If the baby returned to care, obtain:

• Triage time
• Initial appearance
• Bilirubin level
• Neurological examination
• Phototherapy start time
• IV treatment
• NICU consultation
• Transfer records
• Exchange transfusion records

Neurological Records

When bilirubin encephalopathy or kernicterus is suspected, potentially important records include:

• Neonatology consultations
• Neurology consultations
• EEG
• Brain MRI
• Hearing evaluation
• Auditory brainstem response testing
• Movement-disorder evaluation
• Developmental assessments

Whenever possible, preserve copies of the actual MRI and other imaging, not merely the radiology report.

Long-Term Records

Permanent bilirubin injury may require years of follow-up.

Save:

• Audiology
• Hearing devices or cochlear implant records
• Pediatric neurology
• Physical medicine and rehabilitation
• Physical therapy
• Occupational therapy
• Speech therapy
• Feeding therapy
• Communication devices
• Developmental pediatrics
• School evaluations
• IEPs
• Mobility equipment

What Kentucky Parents Can Do After Severe Newborn Jaundice

1. Get Immediate Medical Help for Concerning Neurological Symptoms

Severe jaundice accompanied by abnormal neurological signs requires prompt professional medical evaluation.

Current medical references identify potentially serious findings such as:

• Extreme lethargy
• Poor feeding
• High-pitched cry
• Stiffness
• Floppiness
• Back or neck arching
• Abnormal eye movements
• Seizures

Parents should not try to determine at home whether a baby’s bilirubin has reached a dangerous level.

2. Ask for the Actual Bilirubin Numbers

Ask:

• What is the TSB?
• What was the previous value?
• How fast is it rising?
• What is the applicable phototherapy threshold?
• Is the baby near the escalation-of-care threshold?
• When will bilirubin be checked again?

The treating medical team should make treatment decisions based on the baby’s individual circumstances.

3. Request Complete Records

Request records from:

• Birth hospital
• Pediatrician
• Emergency department
• Laboratory
• NICU
• Transport service
• Neurologists
• Audiologists
• Rehabilitation providers

4. Build a Bilirubin Timeline

Record each known:

• Bilirubin measurement
• Age in hours
• Phone call
• Follow-up visit
• Treatment
• Admission
• Transfer

A clear timeline helps both medical and legal review.

5. Preserve Communications

Save:

• Patient portal messages
• Telephone notes
• Discharge papers
• Appointment reminders
• Lab notifications
• Emails
• Text communications from healthcare systems when relevant

6. Keep Long-Term Developmental Records

Kernicterus can affect movement, hearing, communication, and other functions.

Save records showing how the condition actually affects the child over time.

7. Have Kentucky Deadlines Evaluated Early

Kentucky malpractice deadlines depend on the claimant, defendant, and legal forum.

Families should not assume that every claim involving an injured newborn automatically remains open until adulthood.

Advanced Newborn Care in Kentucky

A baby with severe hyperbilirubinemia may sometimes need treatment beyond what the birth hospital can provide.

The treating physicians determine whether transfer is medically appropriate and where the baby should go.

Golisano Children’s at UK — Lexington

The former Kentucky Children’s Hospital is now Golisano Children’s at UK.

UK HealthCare operates a Level IV neonatal intensive care unit in Lexington for critically ill newborns.

The hospital also provides follow-up through its NICU Graduate Clinic.

Kentucky Kids Crew

UK HealthCare’s Kentucky Kids Crew provides hospital-to-hospital critical-care transportation for newborn and pediatric patients.

The specialized transport team is available 24 hours a day, seven days a week.

Transport can occur by specially equipped ground ambulance or air depending on the medical circumstances.

Norton Children’s Hospital — Louisville

Norton Children’s Hospital operates a Level IV NICU in downtown Louisville.

Babies from throughout Kentucky and the surrounding region are referred there for advanced neonatal care.

“Just for Kids” Transport Team

Norton Children’s “Just for Kids” Transport Team provides specialized neonatal and pediatric inter-hospital transportation.

The service operates 24/7 by ground and air.

These facilities are listed as Kentucky treatment resources only. Their inclusion does not imply negligence or wrongdoing by either health system or any provider.

Kentucky Law and Kernicterus Birth Injury Claims

Kentucky’s General Medical Malpractice Deadline

Under the current version of KRS 413.140, malpractice actions against covered physicians, surgeons, dentists, and hospitals generally must be commenced within one year after the cause of action accrues.

For covered medical malpractice claims, the statute provides that the claim accrues when the injury is discovered or, through reasonable care, should have been discovered.

KRS 413.140 also contains a five-year outside provision measured from the alleged negligent act or omission.

Deadline issues can be complicated in a kernicterus case because the baby’s serious neurological injury may not be fully understood when jaundice first occurs.

The deadline should be analyzed based on the actual claim and defendants.

Does Kentucky Toll the Deadline for an Injured Newborn?

KRS 413.170 provides tolling protection for certain claims when the person entitled to bring the action was an infant—meaning a minor—when the claim accrued.

Because KRS 413.140 falls within the range of statutes identified by KRS 413.170, minority can materially affect an injured child’s own medical malpractice claim.

But it is too broad to say that every claim associated with kernicterus automatically remains open until the child becomes an adult.

Different rules may apply to:

• A parent’s independent claim
• An estate claim
• Wrongful death
• State agencies or institutions
• State employees
• Claims governed by another statutory process

Each claimant and defendant should be analyzed separately.

Special Rules Can Apply to UK HealthCare and Other State Institutions

This issue is particularly relevant on Kentucky birth-injury pages because the University of Kentucky is a state institution.

Under KRS 49.070, state institutions of higher education are treated as state agencies for purposes of Kentucky’s Board of Claims provisions.

The Board of Claims has primary and exclusive jurisdiction over certain negligence claims involving the Commonwealth, state agencies, and employees acting within the scope of state employment.

KRS 49.120 contains separate filing deadlines for those claims.

For medical malpractice matters before the Board:

• Claims generally must be presented within one year after accrual.
• Medical malpractice uses a discovery rule.
• The statute contains a three-year outside period.
• A guardian, next friend, or other qualified representative must bring a minor’s claim within the Board’s applicable deadline.

Importantly, KRS 49.120 states that its rule for claimants under legal disability applies notwithstanding KRS 413.170.

Families should therefore not assume that ordinary infancy tolling automatically applies to a possible claim involving a state institution.

Whether a particular UK HealthCare provider, entity, employee, or claim actually falls within the Board of Claims system requires individualized legal analysis.

Kentucky’s Certificate-of-Merit Requirement

Kentucky also requires an important filing step in many medical malpractice lawsuits.

Under KRS 411.167, a claimant beginning a covered medical malpractice action generally must file a certificate of merit with the complaint.

The certificate ordinarily states that:

• The facts have been reviewed
• The claimant or attorney consulted with at least one qualified medical expert
• The expert is knowledgeable about the relevant medical issues
• The consultation supports a reasonable basis for filing the action

The statute contains specified exceptions and alternative procedures.

It also addresses circumstances where medical records have been requested but not yet provided.

Promptly obtaining bilirubin, treatment, discharge, and neurological records can therefore be important well before suit is filed.

Did Kentucky Add a New Medical-Malpractice Pre-Suit Notice Requirement in 2026?

No new general medical-malpractice pre-suit notice requirement from 2026 Senate Bill 195 became part of the enacted law.

The bill as originally introduced contained proposals involving:

• Medical-malpractice prelitigation notice
• A written medical opinion
• Changes to KRS 411.167
• Changes to KRS 413.140

Those provisions were removed during the legislative process.

The enacted version of SB 195 concerned other civil-liability issues and did not enact those proposed medical-malpractice provisions.

For current cases, lawyers should rely on the actual statutes in effect rather than summaries of an earlier version of the 2026 bill.

Does Kentucky Require a Medical Review Panel?

No.

Kentucky once enacted a mandatory medical review panel process for many malpractice claims.

The Kentucky Supreme Court held that law unconstitutional in Commonwealth ex rel. Meier v. Claycomb.

Parents therefore do not have to go through the former medical review panel system before filing a covered claim.

That should not be confused with the separate certificate-of-merit requirement under KRS 411.167.

Do Kernicterus Cases Require Medical Experts?

Usually.

A kernicterus case can involve specialized questions about:

• Neonatology
• Newborn pediatrics
• Bilirubin screening
• Hemolysis
• G6PD deficiency
• Feeding and weight loss
• Phototherapy
• Exchange transfusion
• Neurology
• Hearing injury
• Causation
• Long-term prognosis

Potential experts may include:

• Neonatologists
• Pediatricians
• Pediatric neurologists
• Pediatric hematologists
• Audiologists or hearing specialists
• Neuroradiologists
• Rehabilitation specialists
• Life-care planners

Kentucky’s KRE 702, amended effective July 1, 2024, governs the admissibility of expert testimony.

Qualified experts generally must connect the alleged failure in care to the bilirubin injury rather than simply pointing to a severe bilirubin result.

Do AAP Guidelines Automatically Establish Medical Malpractice?

No.

The AAP guideline is an important and widely used clinical framework.

It does not by itself determine the legal standard of care in every case.

Experts must consider:

• Gestational age
• Age in hours
• Clinical condition
• Risk factors
• Information known at the time
• Available resources
• Bilirubin trend
• Feeding and weight
• Treatment response
• Hospital capabilities
• Other medical circumstances

A guideline can provide important context without automatically proving negligence.

Who Could Be Responsible for Preventable Kernicterus?

Depending on the evidence, an investigation may examine care provided by:

• Newborn nursery physicians
• Pediatricians
• Neonatologists
• Family physicians
• Nurses
• Emergency department providers
• Laboratory systems
• Hospital or health system
• Outpatient pediatric practices

Potential institutional issues can involve:

• Screening protocols
• Lab-result communication
• Discharge procedures
• Follow-up systems
• Parent education
• Escalation policies
• Transfer procedures

The involvement of any provider or institution does not by itself establish liability.

Can the Hospital Be Responsible or Only the Pediatrician?

Potentially either, both, or neither.

Questions can include:

• Who was responsible for predischarge screening?
• Who received the bilirubin result?
• Who made the discharge decision?
• Who was responsible for arranging follow-up?
• Was responsibility transferred to an outpatient pediatrician?
• Did the pediatrician receive the necessary information?
• Was treatment delayed after a critical result?
• Did hospital systems contribute to the delay?
• Were the providers employees, contractors, agents, or state employees?

These relationships can affect liability and where a claim must be brought.

What Long-Term Problems Can Kernicterus Cause?

Permanent bilirubin brain injury may affect several areas of development and function.

Potential consequences can include:

• Dyskinetic or athetoid cerebral palsy
• Hearing loss
• Auditory neuropathy
• Abnormal muscle tone
• Movement disorders
• Speech and communication difficulties
• Dental enamel abnormalities
• Visual or gaze abnormalities
• Developmental disabilities in some children

Long-term care may involve:

• Pediatric neurology
• Audiology
• Hearing aids
• Cochlear implants
• Physical therapy
• Occupational therapy
• Speech therapy
• Assistive communication
• Rehabilitation
• Educational support
• Mobility equipment
• Personal care assistance

Potential legal damages depend on the evidence and Kentucky law.

A diagnosis alone is not enough to responsibly estimate the value of a case.

What if Severe Jaundice Results in a Child’s Death?

Kentucky wrongful-death claims are governed in part by KRS 411.130.

The statute provides that a wrongful-death action is brought by the deceased person’s personal representative.

Wrongful-death claims present different deadline and procedural questions from a living child’s personal malpractice claim.

Parents should therefore not rely on infancy tolling applicable to some claims belonging to a living child when evaluating a fatal-injury case.

Frequently Asked Questions About Kernicterus and Severe Jaundice in Kentucky

Is newborn jaundice common?

Yes.

The AAP states that more than 80% of newborn infants develop some degree of jaundice.

Most cases do not cause permanent injury.

What is kernicterus?

Kernicterus is permanent neurological injury caused by severe bilirubin toxicity in the brain.

Potential effects include movement disorders, cerebral palsy, hearing loss, auditory neuropathy, and other neurological problems.

Is kernicterus preventable?

Appropriate identification and treatment of dangerous hyperbilirubinemia can prevent many cases of bilirubin-related brain injury.

However, whether a particular child’s injury could reasonably have been prevented requires individualized medical review.

Should every newborn have a bilirubin test before discharge?

For newborns 35 weeks’ gestation or older, the AAP’s 2022 guideline recommends an objective bilirubin measurement between 24 and 48 hours after birth or before discharge if discharge occurs earlier.

Is looking at the baby’s skin enough to determine the bilirubin level?

No.

Visual jaundice assessment can be useful clinically, but the AAP recommends objective TcB or TSB measurement rather than relying on appearance alone.

What is the difference between TcB and TSB?

TcB is a transcutaneous estimate obtained through the skin.

TSB is a total serum bilirubin measurement obtained from blood.

The AAP identifies TSB as the definitive test for phototherapy, escalation-of-care, and exchange-transfusion decisions.

Do doctors still use the Bhutani bilirubin nomogram?

The 2022 AAP guideline replaced the old Bhutani risk-zone approach for routine post-discharge follow-up.

Current follow-up decisions are based largely on how far the predischarge bilirubin is below the baby’s applicable phototherapy threshold.

Can a cephalohematoma increase jaundice risk?

Yes.

The AAP lists scalp hematoma or significant bruising as a risk factor for developing significant hyperbilirubinemia.

What is the escalation-of-care threshold?

Under the AAP guideline, the escalation-of-care threshold is 2 mg/dL below the baby’s applicable exchange transfusion threshold.

Reaching that level is treated as a medical emergency.

When is exchange transfusion necessary?

The AAP recommends urgent exchange transfusion when the TSB reaches the applicable exchange-transfusion threshold or when the infant has certain signs of intermediate or advanced acute bilirubin encephalopathy.

Treatment decisions belong to the baby’s medical team.

Can poor feeding contribute to jaundice?

Inadequate intake during the first days of life can contribute to significant unconjugated hyperbilirubinemia.

Feeding adequacy, weight loss, bilirubin, and other risk factors should be considered together.

Can kernicterus cause cerebral palsy?

Yes.

Kernicterus can cause a characteristic dyskinetic or athetoid form of cerebral palsy and other neurological impairments.

What records are most important in a kernicterus case?

Commonly important evidence includes:

• Every bilirubin result with date and time
• Predischarge TcB or TSB
• Phototherapy thresholds
• Phototherapy records
• Feeding and weight records
• Blood type and DAT/Coombs testing
• Hemolysis evaluation
• G6PD testing when performed
• Discharge instructions
• Follow-up scheduling
• Readmission records
• Transfer records
• Exchange-transfusion records
• Neurology and audiology records
• MRI and other imaging

Where can severe newborn jaundice be treated in Kentucky?

Treatment location depends on severity and the services available at the baby’s hospital.

For infants needing advanced neonatal care, Kentucky has Level IV NICUs including Golisano Children’s at UK in Lexington and Norton Children’s Hospital in Louisville.

Both health systems also operate specialized neonatal transport services.

What is Kentucky’s deadline for a kernicterus malpractice claim?

KRS 413.140 generally provides a one-year limitation period for covered private medical malpractice claims and includes discovery language.

KRS 413.170 can affect some claims belonging to minors.

Different rules can apply to state institutions, parents’ independent claims, wrongful death, and other proceedings.

There is no single safe deadline that applies to every kernicterus case.

Does Kentucky require a medical review panel?

No.

Kentucky’s former mandatory medical review panel law was held unconstitutional.

Does Kentucky require a certificate of merit?

For many covered medical malpractice lawsuits, yes.

KRS 411.167 generally requires a certificate of merit to accompany the complaint, subject to the statute’s exceptions and alternative procedures.

Do I need medical experts?

Usually.

Determining whether dangerous bilirubin levels should have been identified or treated earlier—and whether the delay caused permanent neurological injury—generally requires qualified medical experts.

How Morrin Law Office Evaluates a Kernicterus Case

A severe jaundice case should begin with the actual bilirubin and treatment records rather than an assumption that malpractice occurred.

Our review may involve:

1. Obtaining every bilirubin result with exact collection and reporting times.
2. Calculating the baby’s age in hours at each measurement.
3. Identifying the appropriate AAP phototherapy and escalation thresholds.
4. Reviewing gestational age and bilirubin neurotoxicity risk factors.
5. Reviewing feeding, weight loss, and lactation documentation.
6. Evaluating cephalohematoma, bruising, hemolysis, G6PD deficiency, sepsis, and other risk factors.
7. Reviewing phototherapy orders, start times, and treatment response.
8. Examining discharge instructions and the post-discharge follow-up plan.
9. Reviewing lab-result communication and notification timestamps.
10. Evaluating emergency-department, readmission, transfer, and exchange-transfusion records.
11. Obtaining neurological, audiology, MRI, and developmental records.
12. Consulting qualified medical experts when appropriate.
13. Evaluating whether delayed care caused or materially contributed to permanent bilirubin brain injury.
14. Identifying potentially responsible providers and healthcare entities.
15. Determining whether ordinary Kentucky court procedures or Board of Claims rules may apply.
16. Evaluating Kentucky’s certificate-of-merit requirement and filing deadlines.
17. Documenting the child’s long-term medical, developmental, communication, hearing, and care needs.

Some severe jaundice investigations support a conclusion that preventable failures in screening, follow-up, or treatment caused permanent injury.

Others show that the medical team acted appropriately or that another medical factor explains the outcome.

The purpose of the investigation is to determine what the records and qualified experts actually support.
