Intervention/Methods: Participants who agree to this study of a free literature service will be randomly allocated to Push + Pull versus Pull evidence support. Push + Pull is evidence on pain that is extracted from medical, nursing and rehabilitation journals and appraised for quality and relevance and sent out to clinicians (derived from the successful MacPLUS/Evidence Updates), delivered by e-mail alerts or available for searches of the accumulated database). Pull will be an intervention with a similar front-face but requires clinicians to go to the site and extract evidence from an electronic database. The trial will begin with a 3-month (repeated) baseline, during which average participant use of the standard PULL resource will be monitored. Participants will then be randomly allocated to receive PUSH + PULL or continue to use the PULL resource. After six months, participants will cross over to the alternate intervention for an additional six months. To complete the trial, both groups will finish with three months of PUSH + PULL access.
