How do you cite articles from a "database?"
The first two sources of information about such questions are 


The publisher of the database may have specified how they want to be cited.
In fact, The Cochrane Collaboration has such guidelines:


Cochrane Policy Manual: How to cite our products
Cochrane Reviews: How to cite Cochrane Collaboration products

The APA style guide may have said something already about this data base.
This is also the case:


How to Cite Cochrane Reviews in APA Style
They explain how a journal article style should be used with year as volume and monthly issue:


  Singh, J., Kour, K., &amp; Jayaram Mahesh, B. (2012). Acetylcholinesterase 
  inhibitors for schizophrenia. Cochrane Database of Systematic 
  Reviews, 2012(1), 1–101. doi:10.1002/14651858.CD007967.pub2
  

If these would not have lead to the required information, a more general idea is:
Following the DOI of your example, I end up at a page of the Cochrane library that also has a tab "Cited by". You could have a look there how other people actually cite the report.
If all this had failed, I'd propably have gone for a technical report style citation.
