Last fall, PubMed eliminated the beloved Nursing Journals subset / filter, among others. Read the announcement from the NLM Technical Bulletin.
For those of us who frequently search the nursing literature, this was a handy filter that is sorely missed in PubMed. NLM did offer a workaround, by recommending that individuals save the following search strategy in MyNCBI and pull it up when needed.
Let us know if you've found something that works better ...
Note: I tried to set this up as a custom filter in MyNCBI (hoping it would show up with my other frequently used filters) and be a 1-click solution, but the strategy is too long to work that way and is therefore ignored. Better as a saved search strategy.
