Patients Response to Interventional Care for Chronic Pain Study (PRICS): A Cross-Sectional Survey of Community-Based Pain Clinics in Ontario, Canada.

Background: Non-image guided injection treatments ("nerve blocks") are commonly provided in community pain clinics in Ontario for chronic non-cancer pain (CNCP) but remain controversial.

Aim: We explored patients' perspectives of nerve blocks for CNCP.

Methods: We administered a 33-item cross-sectional survey to patients living with CNCP pain attending four community-based pain clinics in Ontario, Canada.
