Every hospice patient has access to a hospice physician, registered nurse, social worker, nursing aide, hospice volunteer, and chaplain (also known as the interdisciplinary team). For each patient and family, the interdisciplinary team writes a care plan with the patient/family that is used to make sure the patient and family receive the care they need from the team. Typically, full-time registered nurses provide care to about a dozen different families. Social workers usually work with about twice the number of patients/families as nurses. If needed, nursing aides, who provide personal care to the patient, will visit more frequently. All visits, however, are based on the patient and family needs as described in the care plan and the condition of the patient during the course of illness. The frequency of volunteers and spiritual care is often dependent upon the family request and the availability of these services. Travel requirements and other factors may cause some variation in how many patients each hospice staff serves.
