Import Data Structure Export R Export Print Export version Hide definitions SQL version

This is a variable to test import file integrity. It contains the name of the currently used datastructure for import

Standard SwissNeoNet ID number

• 1 = SwissNeoNet informed consent or Hospital GC with UNENCRYPTED data transfer: date of birth can be collected
• 2 = Patient informed but IC not received: if there is no informed consent available but parents have been informed that data will be collected for research and they did not object, the hospital can send data with its own patient or case number as identifier.
• 3 = Anonymized data transfer (request for IC not possible due to early death): if parents neither signed the informed consent form nor were previously informed, or if they reject data collection (veto), data must be entered completely anonymized. Please make sure that this option is not used due to lack of administrative effort because such data cannot be corrected, changed or tested for duplicate entries at a later date because there is no means of identification and data cannot be used for research if it would have been possible to obtain consent!
• 4 = Hospital General Consent with ENCRYPTED data transfer. In such a case, patient data can be sent to SwissNeoNet encrypted using patient or case number.
• 5 = Child born prior to Human Research Act, i.e. < 2015 (prospective data collection stopped)
• 6 = Informed consent status unknown at follow-up (stalled option - status must be known at data entry) See Forms for more details on informed consent

day / month / year
(Year of birth) If parents do not sign informed consent, this item will not be collected. Record Year of birth and use patient number as identifier.

Year in which child was born

• Enter a unique patient identifier for your hospital.
• Mandatory, if parents informed but neither return informed consent nor veto data collection.
• Leave blank if complete anonymity required (will be deleted by system)

female or male or non-determinable at birth

Hospital where infant is born, not place where parents live

admission of child (not mother) to hospital (not clinic / unit)

• If informed consent received: day / month / year
• Else: day of life (date of admission – date of birth + 1)
• (Electronic import: use day of life)

inborn/outborn

• Answer "Inborn" if the infant was delivered at your center.
• Answer "Outborn" if the infant was delivered outside your center. Infants transferred between delivery room of one clinic to intensive care unit of a neighboring clinic do not count as outborn. When completing the Network data forms for outborn infants, use all information available from the hospital that transferred the infant to your center as well as from your own hospital.

Record the best estimate of gestational age at birth in weeks and days using the following hierarchy:

• Obstetrical measures based on last menstrual period, obstetrical parameters, and prenatal ultrasound as recorded in the maternal chart.
• Neonatologist’s estimate based on physical criteria, neurologic examination, combined physical and gestational age exam (Ballard or Dubowitz), or examination of the lens.

The best estimate should be recorded in weeks and days. In instances when the best estimate of gestational age is an exact number of weeks, enter the number of weeks in the space provided for weeks and enter “0” in the space provided for days. Do not leave the number of days blank.

See gestational age in weeks (P_GA_weeks)

first weight measured after birth (weight of tubes, metallic clamps etc. have to be subtracted)

includes stillborns and lifeborns

A=delivered first, B=delivered second, ....

Currently not in use. Individual identifier of mother in Minimal Obstetrcial Dataset (MODS) for future research collaboration.

SES is calculated according to Largo et al. (1990, Dev. Med. Child Neur., 32:30-45) by means of a six-point score of both maternal education and paternal occupation. The lowest possible SES score for either the mother or the father is 1, the highest 6. The overall SES score is a simple addition of the 2 individual scores resulting in a value between 2 and 12.

In 2018, coding was standardized to synchronize areas of profession with years of education. Please consult the SES Scoring Table.

Answer "1" if a clinical or “2” if a histological diagnosis of chorioamnionitis was recorded in the maternal or infant medical record. Answer “3” if both diagnoses were recorded.

• Answer "1" if maternal hypertension, chronic or pregnancy-induced, without edema and/or and proteinuria, was recorded in the maternal or infant medical record, or if a maternal blood pressure above 140 systolic or 90 diastolic was recorded prior to or during the present pregnancy
• Answer "2" if above condition was in combination with edema and/or proteinuria or HELLP was diagnosed

• complete = appropriate dose was given: at least 2 doses, with 24h in between, last dose >24 h before birth, or an equivalent method.
• incomplete = only one dose was given or last dose was less than 24h before birth.

Answer "Yes" if mode of delivery was caesarean section (induced or elective)

Longest occipito-frontal circumf. in cm and mm (e.g. 26.5 cm)

Body length at birth in cm and mm (e.g. 36.5 cm)

Infant’s core body temperature that was measured and recorded within the first hour after admission to your NICU (°C). Core body temperature may be measured by taking a rectal, esophageal, tympanic or axillary temperature.

• minor malformations include: malformations that do not need specific treatment during neonatal period.
• major malformations include: malformations that are lethal or need specific diagnostic or therapeutic interventions during the neonatal period.

See VON Congenital Anomalies list

see congenital malformation

Please indicate if child died in delivery room and continue with item 94 (Date of Death)

Hypoglycemia requiring intravenous glucose Def. Blood sugar < 2.6 mmol/l between 3 - 24h of life

If hypoglycemic, was blood sugar < 2 mmol/l between 3 - 24h of life?

Infant had extrapleural air diagnosed by chest radiograph or needle aspiration (thoracentesis).
For infants who had thoracic surgery and a chest tube was placed at the time of surgery OR if free air was only present on a Chest Radiograph taken immediately after thoracic surgery and was not treated with a chest tube, check NO.
For infants who had thoracic surgery and then later developed extrapleural air diagnosed by Chest Radiograph or needle thoracentesis, check YES.

Antibiotica within first 24h of life?

• culture negative: at least one period of antibiotica during 5 or more consecutive calendar days (regardless of start and end time)
• proven: Clear clinical, radiological, or histological evidence of infection as well as at least one microbiologically relevant positive blood / liquor culture OR at least one microbiologically relevant positive confirmation of pathogen by PCR (new 2020) (if by PCR, add statement "(by PCR") to pathogen)

• Select given if one or several doses, any product
• Specify how many hours and minutes after birth first dose was given
• Specify how many courses were administered (if a course was split up into doses to administer surfactant, count the courses not the doses)

• Count days on which child received O2 for at least 12 hours per day, FiO2 > 21% (21% oxygen is considered room air and does not count as day of O2), prior to reaching 36 0/7 weeks gestational age or discharge home (whichever comes first).
• Saturation levels: lower level 85% up to week 34, 88% thereafter – target level 90%-95%.
• Enter 0 if O2 never required after leaving the delivery room.
• Select Home O2 (item 102) if child discharged on O2.

Any form of mechanical ventilation including high frequency oscillation. Fractions of days (minimum 12 hours) shall be rounded up to one full day. The first day of ventilation does not require 12 hours to be counted as full day.

Continuous airway pressure applied by one nasal tube or double nasal prongs or face mask. Fractions of days (minimum 12 hours) shall be rounded up to one full day.

High Flow Nasal Cannula after Initial Resuscitation – answer number of days at which the infant received air or oxygen (any FiO2) at a flow rate of 2 liters per minute or more via nasal cannula at any time after leaving the delivery room / initial resuscitation area for at least 12 hours per day. Note: Previous definition included all infants with high flow as of 1 l / min in order to match Vermont Oxford definition. This had to be changed to 2 l / min because 1 l / min was not considered clinically relevant in Switzerland and thus led to considerable errors in data collection which were revealed in MNDS audit.

Please render severest finding ever detected on either side. As our definitions follow Papile et al.* , possibly available worse results from other, more sensitive imaging procedures such as CT, MRI or PET should NOT be included.
Indicate if no cerebral ultrasonography was done.
