This manuscript reviews the development and implementation process of the Client Reported Outcome Monitoring Information System in the VA Canada Operational Stress Injury National Network, and reports on outcomes of an evaluation to assess usage, barriers, and facilitators to implementation. The majority of clinicians reported regular use of routine outcomes monitoring, although objective data suggested somewhat lower actual use. In general, clinicians endorsed all barriers and most facilitators as influencing their use of routine outcomes monitoring in a minor way. However, users and non-users differed in their endorsement of facilitators and barriers. Implications for research and implementation efforts are discussed
