Information sources:
Five electronic databases were systematically searched (MEDLINE,
Cumulative Index to Nursing and Allied Health Literature (CINAHL),
Scopus, Embase, and International Pharmaceutical Abstracts (IPA)). The
search strategy was based on Medical Subject Headings (MeSH) and free
text keywords in each database. Search terms included: pregnancy
prevent*, risk manag*, teratogen*, risk perception and perceive*. No
limits were applied to publication dates. Papers not written in English
and conference abstracts were excluded. Reference lists of included
articles were manually screened to identify additional papers for
inclusion in the review. The full search strategy is available in
Appendix 1.
