Distress screening and supportive care referrals used by telephone-based health services: a systematic review.

People affected by chronic diseases such as cancer report high levels of distress and a need for psychosocial support. It is unclear whether telephone-based services for people affected by chronic disease are a practical setting for implementing distress screening, referral protocols and rescreening to direct supportive care where it is needed. This systematic review aimed to describe the published literature regarding distress screening and supportive care referral practices in telephone-based services for people affected by chronic diseases such as cancer.
