The C S T framework (Consultation model, Shared Care model, Takeover model) can be used to describe, understand, assess, and monitor models of care being used by specialist palliative care clinicians and teams in their interactions with primary care providers and other specialist services.
Five domains, help differentiate one model from the other. They are (1) Scope (what aspects of care are addressed by the palliative care clinician?); (2) Prescriber (who prescribes the treatments?); (3) Communication (what communication occurs between the palliative care clinician and the patient's attending clinician?); (4) Follow-up (who provides the follow-up visits and what is their frequency?); and (5) Most responsible practitioner.

Domains displays strengths, limitations, uses, and roles of each model.
This is important because the modes of practice that specialist palliative care teams adopt has many implications for patients, the referrers, the health care system in general, and the palliative care clinicians themselves. Understanding and monitoring the roles of teams and clinicians can support the development of strategies for the long-term sustainability of a service, its impact at community and individual patient levels.
