No Pain+, No Gain!

McMaster University is conducting a study of a new FREE information service for evidence-based pain management.  Pain+ will make keeping up to date and applying the latest research in clinical practice easier for clinicians. To save you time, these articles will be pre-assessed for quality by research staff, and for clinical relevance and interest by practicing clinicians. A wide range of publications from multiple disciplines are surveyed.  As a “one-stop” access to current best evidence from research on pain management, Pain+  offers a searchable database, email alerting system and links to selected resources.  Pain+ was developed as part of a research study comparing two different types of access to pain research evidence. Study participants will be randomly assigned to one of 2 ways of sharing research evidence.  For more information:  Pain PLUS  ~  Contact person:  Margaret Lomotan at or 905-525-9140 ext. 27328
