Personnel and Training Required

Personnel should be trained in medical record abstraction.

Equipment Needs



Requirement CategoryRequired
Average time of greater than 15 minutes in an unaffected individualNo
Major equipmentNo
Specialized requirements for biospecimen collectionNo
Specialized trainingNo

Mode of Administration


Life Stage:

Adolescent, Adult, Pregnancy

Specific Instructions:

The fertility clinic and obstetric medical records provide objective information about medical interventions to achieve pregnancy. Information from the medical record complements the information obtained from the Mode of Conception - Interview protocol and ideally, both modes of administration are used.

Research Domain Information

Release Date:

January 31, 2017


Questions about whether medical intervention of any kind was needed to achieve pregnancy.


Information about natural or assisted conception (i.e., infertility treatments or reproductive technologies) is essential to determine fertility status.

Selection Rationale

This information was abstracted from medical records for the Extremely Low Gestational Age Newborns (ELGAN) project, a major study of low gestational age newborns.
