Introduction People living with complex regional pain syndrome (CRPS), a rare chronic pain disorder, must become experts in their own self-management. Listening to the voice of the patient is often advocated in the pain literature. However, the patient’s option is rarely asked for or considered by clinicians, even when they live with a condition th...

Peripheral intravascular cannula/catheter (PIVC) insertion is a common invasive procedure, but PIVC failure before the end of therapy is unacceptably high. As PIVC failure disrupts treatment and reinsertion can be distressing for the patient, prevention of PIVC failure is an important patient outcome. Consumer participation in PIVC care to prevent...
