Note: UpToDate is an excellent clinical resource, it uses a high level of evidence to support clinical decision making. This resource can give an excellent overview of the best practices in care and while it will refer to primary resources in the article reference lists, no articles in the database are original research. So if you professor has indicated that you need a nursing research article (or primary literature) the articles found here will not be that source (although you could still use UpToDate in other sections of your paper.)
Continued access: UpToDate requires that users create a secondary login and then UpToDate may be used from off-campus (directly through their website, or through the app) using only that authentication. Periodically, you will need to log-in using the link above to show that you are a current SPU student or faculty member in good standing.
Citing an UpToDate reference, APA 6th & 7th edition:
(although not required for most APA references, UpToDate references must provide a retrieval date because the content will change over time)

The above is only a select list of SPU databases most frequently used when reviewing the nursing literature. There could be times when other databases would be helpful - for example if you were looking for information about nursing malpractice, you might want to search the database 'Legal Collection.'
