Table 2. Terms used in systematic database literature search.

Category	PubMed, Medline, Web of Science, Cochrane, CINAHL, Scopus	ERIC*
A: School Nurse	school-nurs* (only in title)	“school nurse”
B: Method	review*OR meta-analysis	Review OR reviews
C: Excluded terms	Barrier* OR role*OR framework	NOT barrier NOT barriers NOT framework NOT frameworks NOT role NOT roles

Notes. Categories were combined into a search string as follows: A and B NOT C.

*The database ERIC did not recognize the word “meta-analysis”. Therefor this search term was removed. ERIC does not have the option to use “*” to show all endings to a word. The hyphen between “school” and “nurse” showed no results. To avoid search results with only “school” or only “nurse” ERIC gives the option of enclosing a term in quotation marks. For this reason, our search string had to be adapted.
