Things that go wrong in the NICU
The short answer
The NICU is one of the highest-risk environments in medicine. Very small patients, weight-based dosing, many devices, and constant handovers. Most NICU care is excellent and errors still happen. 1
This page sets out the recurring categories, what monitoring standards exist, and how to ask about them. It is written to help you be an effective advocate, not to make you suspicious of the people caring for your baby.
The numbers, up front
- Levels of care are defined
- Neonatal care is formally organized into levels, with defined capabilities at each, and babies are expected to be cared for at a level matched to their needs 1
- Transfer before birth is safer
- Where a very preterm birth is expected, transferring the mother before delivery is generally safer than transferring the baby afterward 1
- Weight-based dosing
- Newborn medicines are dosed per kilogram, so a small error in weight or decimal place produces a large error in dose 2
- Bilirubin has a published standard
- Treatment thresholds are set by hour of age, gestational age and risk factors, with defined follow-up after discharge 3
- Glucose has a published standard
- Which babies to screen and when is set out in guidance, and screening is by risk factor rather than by symptoms 4
- Discharge is a defined process
- Discharge of a high-risk newborn involves specific criteria and a follow-up plan, not simply reaching a weight 5
What is it?
A NICU manages babies who cannot yet manage themselves. That means lines, tubes, monitors, ventilators, infusions and constant adjustment, in patients who weigh a few hundred grams to a few kilograms.
The recurring categories of error are these.
Medication and dosing. Weight-based, small volumes, high-risk drugs. See medication errors. 2
Infection. Central lines and prolonged hospital stays are the main routes to late-onset infection. Prevention rests on hand hygiene and line care. 6
Feeding and nutrition. Advancing feeds, recognizing feeding intolerance, and identifying necrotizing enterocolitis early. 7
Airway and breathing. Tube position, unplanned extubation, ventilator settings, and oxygen targeting. 8
Monitoring and alarms. Alarms that are silenced, thresholds set too wide, or trends not acted on.
Screening not done on schedule. Head ultrasounds, eye screening, hearing screening, bilirubin and glucose all have schedules. 3 4 9
Handover. Information lost between shifts or between teams.
Discharge. Leaving without a follow-up plan, without hearing results, or without the right equipment and training. 5
What does standard care look like?
Care at the right level. Levels of neonatal care are formally defined, and a baby should be cared for at a level matched to their needs, with transfer before birth where possible. 1
Weight-based dosing with double-checking. 2
Screening on schedule. Head ultrasounds in very preterm babies, eye screening for retinopathy, newborn hearing screening, glucose screening by risk factor, and bilirubin by hour of age. 10 9 4 3
Infection prevention, including hand hygiene and central line care. 6
Targeted oxygen, since both too little and too much cause harm. 11
Human milk prioritized, including donor milk where available, given the association with lower rates of necrotizing enterocolitis. 7
A structured discharge process with criteria and a written follow-up plan. 5
What can go wrong?
A medication or dosing error. 2
A line infection, or infection not recognized early. 6
Feeding intolerance not acted on, so necrotizing enterocolitis advanced. 7
A breathing tube in the wrong position, or an unplanned extubation not managed quickly.
Oxygen not targeted, contributing to eye or lung injury. 11
Screening missed. A head ultrasound not done, eye screening not done, hearing screening not done or the referral not followed up, glucose not checked in an at-risk baby, or bilirubin not measured against the thresholds. 9 4 3
Enlarging ventricles not tracked after a brain bleed. 12
Care at a level that did not match the baby's needs, or transfer delayed. 1
Discharge without a follow-up plan, or without hearing results, or without developmental follow-up arranged. 5
Whether any of this amounts to a departure from the standard takes a physician expert reading the whole record.
Which injuries can follow?
The injury follows the error.
- Neonatal sepsis and meningitis from infection. 6
- Necrotizing enterocolitis. 7
- Kernicterus from untreated jaundice. 3
- Low blood sugar brain injury. 4
- Hydrocephalus where enlarging ventricles were not tracked. 12
- Retinopathy of prematurity, from oxygen and from missed screening. 8
- Hearing loss identified late. 9
- HIE from a period of low oxygen. 13
What does this look like in the records?
Ask for the complete NICU record, which is large. Specify:
- Daily progress notes.
- The medication administration record, including the weight used for dosing. 2
- Nursing flow sheets, including vital signs and oxygen settings.
- Ventilator settings and blood gas results.
- Every imaging report with its date: head ultrasounds, MRI, X-rays. 10
- Every laboratory result with times, particularly bilirubin and glucose. 3 4
- Screening results: hearing, eyes, newborn screen. 9
- The discharge summary and the written follow-up plan. 5
While you are still there
Keep your own log. Date, time, what was said, who said it. The NICU binder pack prints out with daily log sheets, a questions log and a medication log.
How to ask without becoming the difficult parent
Ask specific, answerable questions. "What is the plan for today?" "What are we watching for?" "What number would change the plan?" Those are the questions that get real answers and that help the team as much as you.
What can you do this week?
- Request the complete labor and delivery record for you and your baby. The records request builder writes the letters for you.
- Write down what you remember while it is fresh, using the delivery timeline builder.
- Read how to read your labor and delivery records before the records arrive.
- Check the deadline to file in your state with the statute of limitations lookup.
Questions parents ask
How do I raise a concern without making things worse?
Ask specific questions rather than general ones, and ask them of the person who can answer. "What is the plan for feeds today, and what would make you pause them?" gets a better answer than "is everything okay?" If you remain concerned, ask to speak to the attending physician or the charge nurse, and ask for the answer in the notes.
Can I ask for a second opinion in the NICU?
Yes. It is a normal request and a reasonable one. Ask how to arrange it, and ask for the request to be documented. It does not mean you distrust the team; it means you want another set of eyes on a serious decision.
What should I make sure happens before discharge?
Hearing screening results and any follow-up appointment. 9 Eye screening arrangements if your baby needs them. A written follow-up plan including developmental follow-up. 5 Any equipment, with training. A medicine list with doses. A written plan for what to do if you are worried at home. See going home from the NICU.
Should my baby be at a different hospital?
Levels of neonatal care are formally defined, and a baby should be cared for at a level matched to their needs. 1 It is a fair question to ask directly: "Is this the right level of unit for my baby, and at what point would you transfer?"
Words on this page, in plain English
- bilirubin
- A yellow substance made when the body breaks down old red blood cells. High levels turn the skin and eyes yellow.
