This chapter presents a checklist of elements which if a therapist misses may severely compromise his/her ability to successfully implement and demonstrate the impact of his/her patient self-referral service. The list includes: being clear about what kind of patient self-referral service best meets the needs of the therapist's population, the local geography and the capabilities of his/her service; being clear what the service will be called; worked out how patients will refer themselves to the service; possessing a publicity strategy; identified all organisational, clinical and service key objectives that are relevant to his/her service; produced an impact plan; and developed an agreed dataset.
