Introducing single-session walk-in counselling services in a counselling agency virtually eliminated a lengthy wait list and reduced costly no-shows for scheduled counselling. A pilot study found that client distress decreased significantly following the single session, and a high proportion of clients were "ready for change." The service diverts clients from using hospitals and family doctors/walk-in clinics and toward using community social services. It also enables an earlier return to work and usual activities. The social benefits (reduced hospital use and faster return to work) exceed the cost of the service. This information is helping to make the case for sustaining and expanding these services.
