  • 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.

18 mndsb34 SES_Education_mother sesEducationMother Highest education mother text / choice_select unknown 2000 3000 no
 

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.
