RecruitingBehavioural interventionM2VA Pain Care PathwayThe goal of this 2-cohort, cluster randomized, type 2 hybrid trial is to test the effectiveness, cost-effectiveness and patient-level effects of an implementation facilitation strategy in helping M2VA case managers adopt a Military2VA Pain Care Pathway (M2VAPCP) intervention. The main questions it aims to answer are: Will adding implementation facilitation to training-as-usual for M2VAPCP result in a higher proportion of Veterans who receive M2VAPCP compared to training-as-usual alone? Will adding implementation facilitation to training-as-usual for M2VAPCP result in better adherence to the M2VAPCP protocol compared to training-as-usual alone? Will implementation facilitation improve Veterans' clinical outcomes (pain, risky substance use) and increase the number of non-pharmacological pain treatments used compared to training-as-usual alone?
