Care coordination, consistency and continuity: the case of the key worker role in children's cancer care.

The role is complex and diverse, responding to local needs. Certain conditions, (e.g., high caseload) placed limits on enacting the three pillars, diminishing the positive experience of families. When they worked well, key workers reduced the fragmented nature of services and families placed great value on keeping the same key worker from diagnosis into long-term care. Retaining these roles, where already in place, or including, if not, we would recommend, factoring into budgets to sustain and expand such roles.
